Description

Adjusting mechanism, adjusting device for a child carrier, and adjusting device for a child carrier

The present invention relates to the technical field of children's supplies, and more particularly to an adjustment mechanism, an adjustment device for a baby carrier, and a baby carrier.

Infant carriers, such as safety baskets and car seats, typically consist of a seat and a backrest. To enhance comfort, the backrest is typically pivoted relative to the seat, allowing the angle between the two to be adjusted as needed, allowing the child to sit or lie down. However, currently available infant carriers fail to accommodate the diverse seating positions of infants of different ages, such as sitting, reclining, and lying flat. This compromises infant comfort and hinders the promotion of infant carriers. Although some baby carriers on the market (such as safety seats) offer adjustable recline angles between the backrest and seat, the internal angle adjustment mechanisms are complex and prone to getting stuck during adjustment, making them difficult to operate and resulting in poor stability in angle adjustment. Furthermore, the numerous components contribute to excessive weight, impacting the user experience.

According to various embodiments of the present invention, an adjustment mechanism, an adjustment device for a baby carrier, and a baby carrier are provided.

To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided with reference to the accompanying drawings. Numerous specific details are provided in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

An embodiment of the present invention provides a baby carrier 1000, which can be, for example, a baby basket or a baby seat. Specifically, in the present invention, the following description uses the baby carrier 1000 as an example of a baby basket.

Figures 1 and 2 schematically illustrate perspective views of a baby carrier (i.e., a baby carrier 1000) according to a first embodiment of the present invention. The baby carrier includes a seat portion 100, a backrest portion 200, a pivot structure 400 (see Figures 6 and 7), and an adjustment mechanism 500 (see Figures 11 and 12).

Referring to Figures 1 to 3 , in some examples, the seat portion 100 and the backrest portion 200 are arranged at an angle to form a seating space 300. The backrest portion 200 supports the infant's upper body (e.g., head and back), while the seat portion 100 supports the infant's lower body (e.g., hips and legs). The seat portion 100 may include a shell 110 and a legrest portion 150. The backrest portion 200 and the shell 110 are pivotally connected to form the seating space 300 for supporting the infant. In this first embodiment, the legrest portion 150 and the shell 110 are integrally formed. In other embodiments, the legrest portion 150 and the shell 110 may be fixedly connected by screws, riveting, or welding. The backrest 200 has at least two angular positions relative to the shell 110 to accommodate different seating needs of infants, such as different angles for sitting and lying positions. For example, the first usage position of the backrest 200 and the shell 110 shown in Figures 1 and 3 is suitable for a lying infant, while the second usage position of the backrest 200 and the shell 110 shown in Figures 4 and 5 is suitable for a sitting infant. It should be understood that the backrest 200 and the shell 110 can be set to more or less than two angular positions as needed, and the present invention is not limited thereto. Furthermore, it should be understood that the correspondence between the first and second usage states of the backrest portion 200 and the shell 110 and the infant's posture on the infant carrier 1000 is merely exemplary and does not necessarily correspond to the infant's lying position or sitting position, respectively. For example, the first usage state may be applicable to the infant's sitting position, and the second usage state may be applicable to the infant's lying position, and so on. The present invention is not limited to this.

In some embodiments, when the backrest 200 of the baby carrier 1000 is adjusted relative to the shell 110 to a suitable lying position for an infant, the angle between the backrest and the horizontal direction is greater than the angle between the legrest and the horizontal direction. This ensures that the infant's legs are not higher than the head when lying flat, thereby improving the infant's comfort.

A latching member 800 is provided on the side of the seat portion 100 facing away from the passenger space 300. This latching member 800 is primarily used to latch onto the carrier base of a car seat, thereby securely securing the baby carrier to the car seat. Specifically, the latching member 800 is a rod-shaped structure that is fixedly connected to the bottom of the seat portion 100 via a fastener (such as a screw or bolt) or is directly integrally formed with the bottom of the seat portion 100.

To facilitate transporting the baby basket, in some examples, as shown in Figures 1 and 3 , the baby basket further includes a handle 7000 connected to the seat portion 100 or the backrest portion 200. Optionally, the handle 7000 is attached to the seat portion 100 or the backrest portion 200 in a detachable or non-detachable manner. In this first embodiment, the housing 110 is provided with a handle coupling portion 102 (see Figure 6 ), and the handle 7000 is detachably pivoted to the handle coupling portion 102 of the seat portion 100. Thus, when the baby basket needs to be transported, the handle 7000 is rotated away from the seat portion 100 or the backrest portion 200, making it easier for the user to hold the basket. When the baby basket is no longer needed, the handle 7000 is rotated closer to the seat portion 100 or the backrest portion 200 to prevent the handle 7000 from obstructing the baby's view and making it easier for the user to place the baby in or take the baby out of the basket.

In this first embodiment, the seat portion 100 can also be pivotally connected to the backrest portion 200. In other embodiments, the seat portion 100 and the backrest portion 200 can also be fixedly connected, that is, the seat portion 100 and the backrest portion 200 cannot move relative to each other. Specifically, in this first embodiment, one end of the seat portion 100 is pivotally connected to one end of the backrest portion 200, that is, the angle between the two can be adjusted. In this way, the baby basket can have at least two usage states. For example, the first usage state shown in Figures 1 and 3 (when the baby is lying in the baby basket) or the second usage state shown in Figures 4 and 5 (when the baby is sitting in the baby basket), etc. Of course, at least one transition state can be provided between the first and second usage states. This allows the user to adaptively adjust the angle between the seat portion 100 and the backrest portion 200 based on the infant's state (e.g., sleeping, awake), thereby enhancing the infant's comfort while sitting in the baby carrier.

Referring to Figures 4 to 7, in some examples, the backrest portion 200 and the seat portion 100 are pivotally connected via the pivot structure 400. Specifically, the front end of the backrest portion 200 and the rear end of the seat portion 100 are pivotally connected via the pivot structure 400. More specifically, the pivot structure 400 includes a first pivot fitting portion, a second pivot fitting portion, and a mating connector. The first pivot fitting portion is provided on one of the seat portion 100 and the backrest portion 200, and the second pivot fitting portion is provided on the other of the seat portion 100 and the backrest portion 200. The seat portion 100 and the backrest portion 200 are pivotally connected via the first pivot fitting portion and the second pivot fitting portion. The mating connector pivotally connects the first pivotally mating portion and the second pivotally mating portion.

Specifically, the first pivoting portion includes a pivoting member 420, the second pivoting portion includes a pivoting seat 430, the pivoting seat 430 having a first engaging slot 431, and the mating connector includes a pivoting cover 440 having a second engaging slot 441. The first engaging slot 431 and the second engaging slot 441 together form a pivoting slot 410. At least a portion of the pivoting member 420 is inserted into and rotatable within the pivoting slot 410, enabling the baby carrier 1000 to switch between a first usage state and a second usage state. In the first embodiment, as shown in Figures 6 and 7 , the pivot seat 430 is disposed on the backrest portion 200 , and the pivot member 420 is disposed on the seat portion 100 .

It should be noted that the "front end" herein refers to the end of the seat portion 100 distal from the backrest portion 200, and the "rear end" refers to the end of the backrest portion 200 distal from the seat portion 100. More specifically, the "front end" refers to the end of the baby carrier closer to the infant's feet, and the "rear end" refers to the end closer to the infant's head. Furthermore, unless otherwise expressly specified or limited, the "front," "rear," "left," and "right" directions of the baby carrier (i.e., the baby carrier 1000) in the various embodiments of the present invention may be indicated by arrows F, B, L, and R in the figures. These directional terms are used solely to clarify the description of the embodiments of the present invention and are not intended to unduly limit the scope of protection of the present invention.

Referring to Figures 6 to 10 , the pivot cover 440 is specifically detachably mounted on the pivot base 430. For example, the pivot cover 440 is mounted on the pivot base 430 via a snap-fit connection, or alternatively, the pivot cover 440 is mounted on the pivot base 430 via a threaded connection. Specifically, in this first embodiment, as shown in Figures 6 and 8 , the pivot base 430 is provided with a first connecting hole 432, and the pivot cover 440 is provided with a second connecting hole 442. The pivot cover 440 and the pivot base 430 are connected by fasteners such as connecting screws that pass through the second connecting hole 442 and the first connecting hole 432, respectively.

Referring to Figures 6 to 9 , in some examples, the first engagement groove 431 and the second engagement groove 441 are both arcuate grooves. As shown in Figures 6 and 10 , the pivot member 420 has a curved surface 421 whose curvature matches the curvature of the wall of the pivot groove 410. This improves the smooth rotation of the pivot member 420 within the pivot groove 410. Specifically, in this first embodiment, the first engagement groove 431 and the second engagement groove 441 are both semicircular grooves. Thus, when the two are enclosed, they form the circular pivot groove 410. Of course, in other alternative embodiments, the first engaging groove 431 and the second engaging groove 441 may be other arcuate grooves, as long as the first engaging groove 431 and the second engaging groove 441 together form a completely circular pivot groove 410. For example, when the first engaging groove 431 is a 2/3 arcuate groove, the second engaging groove 441 may be a 1/3 arcuate groove.

In some examples, one of the pivot 430 and the pivot member 420 is integrally formed with the seat portion 100, while the other is integrally formed with the backrest portion 200. In other words, when the pivot 430 is integrally formed with the seat portion 100, the pivot member 420 is integrally formed with the backrest portion 200; and when the pivot 430 is integrally formed with the backrest portion 200, the pivot member 420 is integrally formed with the backrest portion 200. Specifically, based on the foregoing, in this first embodiment, as shown in Figures 8 and 10, the pivot 430 is integrally formed with the backrest portion 200, and the pivot member 420 is integrally formed with the seat portion 100. This improves the structural strength of the pivot structure 400, thereby enhancing pivoting reliability. Of course, in other alternative embodiments, one of the pivot base 430 and the pivot member 420 can be detachably connected to the seat portion 100, while the other can be detachably connected to the backrest portion 200. By integrally molding the pivot structure 400 with the seat portion 100 and the backrest portion 200, a pivoting connection between the backrest and the seat is achieved, eliminating the need for separate pivot shafts and pivot holes. This reduces the number of components, simplifies the lie-flat function, and makes adjustment more stable and reliable, while also reducing the overall weight of the baby carrier.

In this first embodiment, the pivot seat 430 is located at the end of the backrest portion 200 close to the seat portion 100, i.e., the front end of the backrest portion 200. The pivot member 420 is located at the end of the seat portion 100 close to the backrest portion 200, i.e., the rear end of the seat portion 100.

Specifically, the pivot base 430 includes a connecting portion 433 formed on both sides of the first engaging groove 431. The two first connecting holes 432 described above are provided, one on each of the connecting portions 433. In this first embodiment, a bracket 120 is formed on the seat portion 100. The bracket 120 includes a bracket body 121, a bracket bottom wall 122, and two bracket side walls 123. The bracket body 121 is connected to the bracket bottom wall 122 at an angle, and the two bracket side walls 123 are connected to both sides of the bracket body 121 and the bracket bottom wall 122 and are disposed opposite each other. The pivot member 420 is connected between the two bracket side walls 123. A through-hole 130 is defined between the pivot 420, the bracket body 121, the bracket bottom wall 122, and the two bracket side walls 123. The through-hole 130 is adapted to be received by the through-hole 433 to form a connection between the backrest portion 200 and the seat portion 100.

Referring to Figures 8 and 10 , in this first embodiment, the baby carrier is equipped with two sets of the aforementioned pivot structures 400, spaced apart along the left and right sides of the baby carrier. This improves the stability of the backrest portion 200 pivoting relative to the seat portion 100. Of course, one or more sets of the aforementioned pivot structures 400 may be provided as needed, and the present invention is not limited thereto.

Referring to Figures 11 to 14 , the adjustment mechanism 500 is disposed between the seat portion 100 and the backrest portion 200 and is used to adjust the angle between the seat portion 100 and the backrest portion 200 while maintaining the angle therebetween. Specifically, the adjustment mechanism 500 includes a locking member 510, a locking member 520, and a first operating member 530. The locking member 510 is mounted on one of the seat portion 100 and the backrest portion 200 and is provided with a locking recess 511. In this first embodiment, the locking member 520 is a locking pin. The locking member 520 is mounted on the other of the seat portion 100 and the backrest portion 200. The locking member 520 can engage and disengage with the locking recess 511 to lock and release the backrest portion 200 and the seat portion 100. In the first embodiment, the movement direction of the locking member 520 is perpendicular to a width direction of the seat portion 100 or the backrest portion 200. The locking member 520 moves in a direction perpendicular to the width direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200, thereby allowing for greater flexibility in the setting of the movement stroke and path of the locking member 520. Specifically, the locking member 510 is a sheet-like structure, and the plane in which the locking member 510 is located is perpendicular to the transverse width of the seat portion 100 or the backrest portion 200. The locking recess 511 and the sliding recess 512 are both provided on the sheet-like locking member. Therefore, the plane in which the locking recess 511 and the sliding recess 512 are located is also perpendicular to the transverse width of the seat portion 100 or the backrest portion 200.

The first operating member 530 is movably mounted on the other of the seat portion 100 and the backrest portion 200 and has a locked position and an unlocked position along its movement path. The first operating member 530 is operably connected to the locking member 520 to drive the locking member 520 to move on the locking member 510. Specifically, when the first operating member 530 is in the locked position, the locking member 520 is located within the locking recess 511, and the backrest portion 200 is fixed relative to the seat portion 100, i.e., the backrest portion 200 cannot rotate relative to the seat portion 100, thereby maintaining the baby basket in a specific usage state, such as the first usage state or the second usage state. When the first operating member 530 is in the unlocked position, the locking member 520 retracts from the locking recess 511, allowing the backrest 200 to pivot relative to the seat 100. This effectively allows for adjustment of the angle between the backrest 200 and the seat 100. Furthermore, the placement of the locking member 510 on the seat 100 effectively strengthens the adjustment mechanism 500. Since the adjustment mechanism 500 between the backrest 200 and the seat 100 is subject to greater forces during a collision, reinforcing the adjustment mechanism 500 with the locking member 510 helps prevent deformation of the infant carrier during such a collision. In this first embodiment, the locking member 510 is mounted on the seat portion 100. However, the locking member 510 may also be integrally formed with the seat portion 100, as long as it serves to enhance the structural strength of that location. Furthermore, the locking member 510 is positioned at the upper edge of the seat portion 100 or the backrest portion 200, as far away from the pivot structure 400 as possible. This arrangement disperses the stress points throughout the baby carrier, ensuring a more even distribution of force, avoiding concentrated stress and ensuring the impact resistance of the baby carrier.

The structure and operating principle of the adjustment mechanism 500 are relatively simple. Simply by controlling the position of the first operating member 530, the locking member 520 can be moved into or out of the locking recess 511, thereby adjusting the angle between the seat portion 100 and the backrest portion 200. This process is convenient and unlikely to cause jamming, effectively improving the stability of angle adjustment.

Referring to Figures 13 to 15 , in some examples, the locking recess 511 includes at least two locking grooves 5111. The locking member 510 is further provided with a sliding recess 512 that communicates with each of the locking grooves 5111, with the walls of the sliding recess 512 and the walls of the locking grooves 5111 enclosing each other to form a closed structure. The locking member 520 is movably disposed within the sliding recess 512 and each of the locking grooves 5111. When the first operating member 530 is in the locked position (see Figures 11 and 13 ), the locking member 520 is located within one of the locking grooves 5111, and the backrest portion 200 is fixed relative to the seat portion 100. When the locking member 520 is positioned within each locking groove 5111, the angle between the backrest 200 and the seat 100 varies, correspondingly presenting different backrest angles. When the first operating member 530 is in the unlocked position (see Figure 14), the locking member 520 is located within the sliding recess 512, allowing the backrest 200 to pivot relative to the seat 100.

Specifically, in this first embodiment, as shown in FIG15 , one of the locking grooves 5111 is referred to as a first locking groove 5111A, and the other locking groove 5111 is referred to as a second locking groove 5111B. The sliding recess 512 connects the first locking groove 5111A and the second locking groove 5111B. Thus, the locking member 520 can be considered to be movably inserted within the sliding recess 512, the first locking groove 5111A, and the second locking groove 5111B. Specifically, when the first operating member 530 is in the locked position, the locking member 520 can be located in either the first locking groove 5111A or the second locking groove 5111B. More specifically, when the locking member 520 is located in the first locking slot 5111A, the seat portion 100 and the backrest portion 200 are at the first angle, and the baby carrier 1000 is in the first usage state. When the locking member 520 is located in the second locking slot 5111B, the seat portion 100 and the backrest portion 200 are at the second angle, the first angle being greater than the second angle, and the baby carrier 1000 is in the second usage state. In this first embodiment, as shown in Figures 11 and 13 , when the locking member 520 is located in the first locking groove 5111A, the baby basket is in the first use state. At this time, the angle between the backrest portion 200 and the seat portion 100 is referred to as the first angle. When the locking member 520 is located in the second locking groove 5111B, the baby basket is in the first use state. At this time, the angle between the backrest portion 200 and the seat portion 100 is referred to as the second angle. The first angle is greater than the second angle.

Referring to Figures 13 to 15 , in some examples, when the number of locking grooves 5111 is greater than three, the locking grooves 5111 other than the first locking groove 5111A and the second locking groove 5111B may be considered transition grooves 5111C. Such transition grooves 5111C are located between the first locking groove 5111A and the second locking groove 5111B and communicate with both sliding recesses 512. For example, in the first embodiment, there are three locking grooves 5111: the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C. The transition groove 5111C is located between the first locking groove 5111A and the second locking groove 5111B. In other embodiments, the locking grooves 5111 may also be four, for example, including the first locking groove 5111A, the second locking groove 5111B, and two transition grooves 5111C. The two transition grooves 5111C are located between the first locking groove 5111A and the second locking groove 5111B. When the locking member 520 is located within these transition grooves 5111C, the seat portion 100 and the backrest portion 200 are at a third angle, which is greater than the second angle and less than the first angle. The baby carrier is in a transition state between the first and second usage states. Specifically, when the baby carrier is in the transition state, the angle between the backrest 200 and the seat 100 is between the first and second angles. Specifically, the greater the number of transition grooves 5111C, the smaller the adjustment interval for the angle between the backrest 200 and the seat 100. This allows the user to more precisely adjust the angle between the backrest 200 and the seat 100, ensuring that the baby carrier's position better meets the infant's seating needs and provides increased comfort.

7 and 13 to 15 , the sliding recess 512 is located above the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C. Specifically, the locking recess 511 is closer to the pivot structure 400 (or a rotation axis X1-X1 between the seat portion 100 and the backrest portion 200) than the sliding recess 512. To adjust the angle between the seat portion 100 and the backrest portion 200, the locking member 520 is moved upward along the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C into the locking recess 511. To lock the angle between the seat portion 100 and the backrest portion 200, the locking member 520 needs to be moved downward from the locking recess 511 to the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C.

In some examples, the locking grooves 5111 (i.e., the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C) are spaced apart circumferentially around the rotation axis X1-X1 between the seat portion 100 and the backrest portion 200. It should be noted that the rotation axis X1-X1 is the rotation axis along which the pivot member 420 pivots within the pivot groove 410. The sliding recess 512 is an arc-shaped structure, with the arc center of the sliding recess 512 located on the rotation axis X1-X1. Thus, when the locking member 520 exits the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C and returns to the sliding recess 512, the locking member 520 can be moved within the sliding recess 512 by rotating the backrest portion 200.

In this first embodiment, as shown in FIG15 , the sliding recess 512 has a relatively short arc, so it is approximately linear. In other embodiments, the sliding recess 512 can also be designed as a linear shape, as long as the locking member 520 is not obstructed by the first locking groove 5111A, the transition groove 5111C, or the second locking groove 5111B while sliding within the sliding recess 512.

In some examples, the first operating member 530 may be directly operably connected to the locking member 520. Of course, in other alternative embodiments, the first operating member 530 may be indirectly operably connected to the locking member 520. For example, as shown in Figures 13 and 14, the adjustment mechanism 500 may further include a sliding transmission member 540, through which the first operating member 530 is operably connected to the locking member 520. Specifically, the sliding transmission member 540 includes a connecting portion 541 and a transmission portion 542. The locking member 520 is disposed on the connecting portion 541, and the transmission portion 542 is provided with a guide groove 543 that extends obliquely relative to the movement direction of the first operating member 530 (the first direction F1). More specifically, in the first embodiment, as shown in Figures 11 to 14 , the locking member 510 is mounted on the seat portion 100. The first operating member 530 is movably mounted on the backrest portion 200 and has a driving portion 531. The driving portion 531 is capable of sliding in the guide groove 543 to drive the sliding transmission member 540 to move the locking member 520 relative to the locking member 510 in a second direction F2, so that the locking member 520 switches between the sliding recess 512 and the locking recess 511. It should be noted that in this first embodiment, the movement direction of the first operating member 530 (i.e., the first direction F1) is the same as the front-to-back extension direction of the backrest portion 200, and the first direction F1 is perpendicular to the transverse width of the seat portion 100 or the backrest portion 200. The movement direction of the sliding transmission member 540 and the locking member 520 (i.e., the second direction F2) is perpendicular to both the first direction F1 and the transverse width of the seat portion 100 or the backrest portion 200. In existing baby carriers, the locking member 520 often moves in the transverse direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200. In contrast, the locking member 520 in the first embodiment moves in a direction perpendicular to the transverse direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200. This allows for greater flexibility in the design of the movement stroke and path of the locking member 520.

Referring to Figures 11 and 16 , in some examples, the driving portion 531 includes a latch 5311 and a pull block 5312 . The pull block 5312 is U-shaped and has a first retaining cavity 5313 , which is used to retain the driving portion 542 of the sliding actuator 540 . The latch 5311 passes through one sidewall of the first retaining cavity 5313 and the guide slot 543 before connecting with the other sidewall of the first retaining cavity 5313 . This prevents the latch 5311 from disengaging from the guide slot 543 while sliding within it, thereby enhancing the stability of the driving connection between the first operating member 530 and the sliding actuator 540 .

Referring to Figures 2, 13, and 14, in some examples, the first operating member 530 has an operating portion 532. The operating portion 532 is located on the side of the backrest 200 facing away from the passenger space 300 and at the rear end of the backrest 200. The operating portion 532 is exposed through the operating hole 201 of the backrest 200 for easy operation and is connected to the driving portion 531. Thus, a user can directly control the first operating member 530 between the locked and unlocked positions through the operating portion 532, thereby controlling the sliding movement of the driving portion 531 within the guide slot 543.

Referring to Figures 13, 14, and 17, in some examples, the guide slot 543 has a first slot end 5431 and a second slot end 5432 disposed opposite each other. Specifically, the first slot end 5431 is closer to the locking member 510 than the second slot end 5432, and along the movement direction of the first operating member 530 (the first direction F1), the second slot end 5432 is closer to the operating portion 532 than the first slot end 5431. More specifically, when the first operating member 530 is in the locked position (see Figure 13), the driving portion 531 is located at the first slot end 5431. When the first operating member 530 is in the unlocked position (see Figure 14), the driving portion 531 is located at the second slot end 5432. Specifically, when the user pulls the operating portion 532 to move the driving portion 531 from the first slot end 5431 to the second slot end 5432, the driving portion 531 can drive the sliding transmission member 540 to move upward relative to the locking member 510 along the guide direction of the locking slot 5111 (the first locking slot 5111A or the second locking slot 5111B or the transition slot 5111C), thereby driving the locking member 520 to move from the locking slot 5111 to the sliding recess. 512. Thus, the locking member 520 is not restricted by the locking groove 5111, allowing the locking member 520 to move circumferentially within the sliding recess 512 along the rotation axis X1-X1. Therefore, when the first operating member 530 is in the unlocked position, i.e., when the locking member 520 moves to the sliding recess 512, the user can adjust the position of the baby basket by pushing the backrest 200 to rotate it about the rotation axis X1-X1.

Referring to Figure 11 , in some examples, when the locking member 510 is mounted on the inner wall of the seat portion 100, a gap is left between it and the inner wall. The connecting portion 541 of the sliding actuator 540 is U-shaped and has a second retaining cavity 544 for retaining the locking member 510. The locking member 520 passes through one side wall of the second retaining cavity 544, the locking recess 511 or the sliding recess 512 of the locking member 510, and then connects with the other side wall of the second retaining cavity 544. This prevents the locking member 520 from disengaging from the locking recess 511 or the sliding recess 512 during movement, thereby improving the stability of the baby basket angle adjustment.

In this first embodiment, as shown in Figures 11 and 12 , the locking member 520 is connected to the connecting portion 541 of the sliding transmission member 540 via a latch 570. Specifically, the locking member 520 passes through a through-hole 5441 (see Figure 17 ) in the sidewall of the second retaining cavity 544 before connecting to the latch 570. The latch 570 is larger (specifically, its length L1) than the diameter of the through-hole 5441. This allows the latch 570 to abut against the edge of the through-hole 5441, preventing the locking member 520 from separating from the connecting portion 541.

Referring to Figures 11 and 12, in some examples, the adjustment mechanism 500 may further include a mounting frame 550. The mounting frame 550 is fixedly mounted on the backrest portion 200. Alternatively, the mounting frame 550 is fixedly mounted on the backrest portion 200, or the mounting frame 550 is detachably mounted on the backrest portion 200. As shown in Figures 12 and 18, the mounting frame 550 is provided with a strip-shaped slide 551, which extends from the locking recess 511 toward the sliding recess 512. As shown in Figures 12 and 13, the locking member 520 passes through the strip-shaped slide 551 and the connecting portion 541 and is movably inserted into the sliding recess 512 or the locking recess 511. Furthermore, the dimensions of the latch 570 (specifically, its length L1) are greater than the width L2 of the strip-shaped groove 551. This prevents the locking member 520 from disengaging from the strip-shaped groove 551 during movement. When the locking member 520 moves to the sliding recess 512, the user pushes the backrest 200, causing the mounting frame 550 to rotate along with the backrest 200 about the rotation axis X1-X1. Simultaneously, the mounting frame 550 pushes the locking member 520 to rotate about the rotation axis X1-X1 within the locking recess 511, thereby changing the angle between the backrest 200 and the seat 100.

Referring again to Figures 11 and 12 , in some examples, the adjustment mechanism 500 may further include a reset member 560. This reset member 560 abuts between the mounting bracket 550 and the sliding actuator 540. This reset member 560 is used to reset the sliding actuator 540, causing the locking member 520 to move from the sliding recess 512 toward the locking recess 511 (the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C). Specifically, the reset member 560 can be a spring or other type of elastic member. In this first embodiment, the reset member 560 is a spring. As shown in Figure 17 , a third retaining cavity 545 is formed in the sliding actuator 540. As shown in Figures 12 and 13, the spring is housed within the third retaining cavity 545, with one end abutting the bottom wall of the cavity 545 and the other end abutting the mounting bracket 550. This prevents the spring from shifting during compression or retraction. More specifically, a retaining post 546 is positioned within the third retaining cavity 545, onto which the spring is fitted, further preventing the spring from shifting.

The following describes the process of adjusting the baby basket position (the angle between the backrest 200 and the seat 100) with reference to Figures 6, 7, and 12 to 14.

As shown in Figure 13, when the locking member 520 is located in the first locking slot 5111A, the slot wall of the first locking slot 5111A prevents the locking member 520 from moving into the other locking slots 5111, thereby limiting the pivoting of the backrest portion 200 relative to the seat portion 100 and maintaining the baby carrier in a reclining position.

As shown in FIG14 , when the user needs to adjust the position of the baby carrier, that is, to switch the baby carrier from the lying position to the transition position or to the sitting position, the user can pull the operating portion 532 upward in the first direction F1, so that the operating portion 532 drives the driving portion 531 to move upward in the first direction F1. When the operating portion 532 moves upward in the first direction F1, the driving portion 531 can drive the sliding transmission member 540 and the locking member 520 to move upward in the second direction F2 relative to the locking member 510 under the action of the guide groove 543, thereby causing the locking member 520 to withdraw from the first locking groove 5111A into the sliding recess 512, and at the same time, the reset member 560 is compressed. When the locking member 520 moves into the sliding recess 512, it pushes the backrest 200, causing it to rotate about the rotation axis X1-X1 relative to the seat portion 100. Simultaneously, the mounting bracket 550, along with the rotation of the backrest 200, pushes the locking member 520 to move about the rotation axis X1-X1 within the sliding recess 512. When the locking member 520 moves to directly above the transition groove 5111C or the second locking groove 5111B, the user can release the operating portion 532. At this point, the reset member 560 resets, pushing the sliding actuator 540 downward in the direction opposite to the second direction F2, allowing the locking member 520 to enter the transition groove 5111C or the second locking groove 5111B from the sliding recess 512. Specifically, during the downward movement of the sliding actuator 540 in the direction opposite to the second direction F2, the guide groove 543 causes the driving portion 531 to move downward in the direction opposite to the first direction F1, thereby resetting the operating portion 532 and placing the first operating member 530 in the locked position.

In some examples, the adjustment mechanism 500 may be provided with one or more. Specifically, in this first embodiment, two adjustment mechanisms 500 are provided, and the two adjustment mechanisms 500 are spaced apart along the left and right directions of the baby basket. In some examples, the first operating members 530 in each adjustment mechanism 500 are arranged in parallel, and the operating portions 532 of each first operating member 530 are independent of each other. When the state of the baby basket needs to be adjusted, both operating portions 532 can be operated simultaneously. In this first embodiment, as shown in Figure 16, each first operating member 530 shares a common operating portion 532, that is, the driving portion 531 of each first operating member 530 is operated by the same operating portion 532. In this way, the operating portion 532 can simultaneously control the two driving portions 531, thereby simultaneously controlling the two sliding transmission members 540 and the two locking members 520.

The baby carrier and its adjustment mechanism 500 according to the first embodiment of the present invention have at least the following technical advantages: The adjustment mechanism 500 is disposed between the seat portion 100 and the backrest portion 200 for adjusting the angle therebetween. The locking member 510 is mounted on the seat portion 100 or the backrest portion 200, and the first operating member 530 is movably mounted on the backrest portion 200 or the seat portion 100. Because the locking member 520 is movably mounted on the locking member 510 and the first operating member 530 is operably connected to the locking member 520, the position of the locking member 520 on the locking member 510 can be controlled directly by controlling the first operating member 530. Specifically, since the first operating member 530 has the locking position and the unlocking position on its moving path, when the first operating member 530 is located at the locking position, the locking member 520 is confined in the locking recess 511 on the locking member 510, so that the backrest portion 200 can be fixed relative to the seat portion 100, so that the angle between the two remains unchanged; and when the first operating member 530 moves to the unlocking position, the first operating member 530 has driven the locking member 520 to retreat from the locking recess 511, so that the backrest portion 200 can be pivoted relative to the seat portion 100 to adjust the angle between the two. The structure and operating principle of the adjustment mechanism 500 are relatively simple. Simply by controlling the position of the first operating member 530, the locking member 520 can be moved into or out of the locking recess 511, thereby adjusting the angle between the seat portion 100 and the backrest portion 200. This process is convenient and unlikely to cause jamming, effectively improving the stability of angle adjustment.

As shown in Figures 19 to 21 , the second embodiment of the present invention provides a baby carrier 1000. Similar to the baby carrier of the first embodiment, the second embodiment of the present invention also includes a seat portion 100 and a backrest portion 200. Unlike the first embodiment, in the second embodiment, the backrest portion 200 and the seat portion 100 are pivotally connected at a fixed first pivot point 101. Furthermore, the second embodiment of the baby carrier includes an adjustment mechanism disposed between the backrest portion 200 and the seat portion 100, enabling the backrest portion 200 to be shifted between at least two angular positions relative to the seat portion 100. In this second embodiment, to distinguish it from the first embodiment, the adjustment mechanism is referred to as an adjustment device 600. In other words, the adjustment device 600 is a modified example of the adjustment mechanism 500.

Specifically, the seat portion 100 may include a shell 110 and a leg rest portion 150. The backrest portion 200 is pivotally connected to the shell 110 to form a seating space 300 for supporting an infant. In this second embodiment, the leg rest portion 150 and the shell 110 are integrally formed.

The backrest 200 has at least two angular positions relative to the shell 110 to accommodate different seating needs of infants. For example, the first angular position of the backrest 200 and the shell 110 shown in FIG19 is suitable for a sitting infant, the third angular position of the backrest 200 and the shell 110 shown in FIG20 is suitable for a reclining infant, and the second angular position of the backrest 200 and the shell 110 shown in FIG21 is suitable for a supine infant, etc. It should be understood that the backrest 200 and the shell 110 can be set to more or less than three angular positions as needed, and the present invention is not limited thereto. Furthermore, it should be understood that the correspondence between the first, second, and third angular positions of the backrest 200 and the housing 110 and the infant's posture in the infant carrier 1000 is merely exemplary and does not necessarily correspond to an infant's sitting position, a lying position, or a reclining position, respectively. For example, the first angular position may be suitable for an infant's lying position, the second angular position may be suitable for an infant's reclining position, and the third angular position may be suitable for an infant's sitting position, etc. The present invention is not limited thereto.

As shown in Figures 22 to 24 , the shell 110 is provided with the handle coupling 102, which is used to couple with the handle 7000 of the baby carrier 1000. The front is the direction facing the baby when riding in the baby carrier 1000, and the direction from the bottom edge of the shell 110 to the handle coupling 102 is considered the top. The first pivot point 101 is located forward of the handle coupling 102, which improves the impact resistance of the baby carrier 1000. Furthermore, the lower position of the first pivot point 101 helps lower the center of gravity of the baby riding in the baby carrier 1000, thereby enhancing the safety of the baby. Figures 19 to 24 and subsequent figures continue to use arrow "F" to indicate the front, arrow "B" to indicate the back, arrow "U" to indicate the top, and arrow "D" to indicate the bottom. The direction indicated by arrow "F" is the direction the infant faces when riding in the infant carrier 1000.

Figures 25 and 26 illustrate a three-dimensional structure of the baby carrier 1000 according to this embodiment. The first angled position of the backrest portion 200 and the shell 110 of the baby carrier 1000 shown in Figure 25 is suitable for a sitting infant, while the second angled position of the backrest portion 200 and the shell 110 shown in Figure 26 is suitable for a lying infant. Specifically, referring to Figure 27 , the backrest portion 200 includes a backrest body 210, backrest side panels 220 connected to both sides of the backrest body 210, and a backrest extension 230 connected to the lower side of the backrest body 210. When the backrest 200 is pivotally connected to the shell 110, the backrest extension 230 is located on the side of the shell 110 facing the passenger compartment. A headrest 280 for supporting an infant's head is provided on the side of the backrest body 210, distal from the backrest extension 230. This headrest 280 is slidably connected to the backrest body 210, allowing its position relative to the backrest body 210 to be adjusted according to the infant's body size. Referring also to FIG. 28 , the shell 110 is a one-piece structure, generally comprising a shell body 112 and a shell side panel 113 connected to both sides of the shell body 112. The leg support portion 150 is fixed to a side of the housing body 112 away from the backrest extension portion 230 and is used to support the legs of an infant. In this embodiment, the leg support portion 150 and the housing body 112 are integrally formed.

As shown in Figure 29 , the two backrest side panels 220 of the backrest portion 200 are pivotally connected to the two shell side panels 113 of the shell 110. Figure 30 is an enlarged view of point A in Figure 29 , showing the specific pivotal structure between one of the backrest side panels 220 and the corresponding shell side panel 113. At least the lower end of the backrest side panel 220 is located on the inner side of the corresponding shell side panel 113. The backrest side panel 220 has a pivot hole 221 at its lower end. The inner side of the housing side panel 113 has a pivot protrusion 1210, which has a pivot slot (not shown). A pivot shaft (not shown) passes through the pivot hole 221 and the pivot slot on the pivot protrusion 1210 to pivot the backrest side panel 220 to the corresponding housing side panel 113. In other embodiments, the positions of the pivot hole 221 and the pivot protrusion 1210 may be interchanged. Alternatively, the backrest side panel 220 and the corresponding housing side panel 113 may be pivoted using other structures.

As shown in FIG31 , the adjustment device 600 includes a locking mechanism 610 and an operating mechanism 620.

The locking mechanism 610 is disposed between the housing 110 and the backrest 200. The locking mechanism 610 has a locked state that secures the backrest 200 at one of at least two angular positions (e.g., the first angular position or the second angular position) and an unlocked state that allows the backrest 200 to switch between the at least two angular positions (e.g., the first angular position and the second angular position).

In this embodiment, as shown in Figure 31 , the backrest side panels 220 and the shell side panels 113 on both sides of the infant carrier 1000 are equipped with locking mechanisms 610 to achieve smooth adjustment of the angular position of the backrest portion 200. Figure 32 is an enlarged view of point B in Figure 31 , illustrating the detailed structure of the locking mechanism 610 on one side. A mounting portion 710, described below, is provided on the upper edge of the shell 110 facing the passenger space. The mounting portion 710 is provided with at least two engagement grooves 711. The at least two engagement grooves 711 include a third engagement groove 711 and a fourth engagement groove 711. The at least two engagement grooves 711 are arranged in a staggered orientation relative to the front-to-back direction. 32 to 35 , the locking mechanism 610 includes an actuator 611 and a locking pin 612. The actuator 611 includes an actuator body 6111 and a positioning protrusion 6112 protruding from one side of the actuator body 6111. In this embodiment, the actuator 611 is a one-piece molded structure. In other embodiments, the actuator 611 may be connected to the actuator body 6111 and the positioning protrusion 6112 by welding or riveting. The actuator body 6111 is generally a rectangular parallelepiped structure, having a first side 6111a, a second side 6111b, and a third side 6111c. The first side 6111a, the second side 6111b, and the third side 6111c are adjacent to each other. The first side 6111a of the actuator body 6111 is provided with a mounting hole 6111d, into which one end of the locking pin 612 is inserted. The second side 6111b of the actuator body 6111 is provided with a generally rectangular mounting groove 6111e, which communicates with the mounting hole 6111d. In this embodiment, the mounting groove 6111e is a rectangular groove, with a flexible finger 6111f connected to one side wall of the rectangular groove. One of the locking pin 612 and the elastic finger 6111f is provided with a raised portion (not shown), and the other is provided with a recessed portion (not shown). When the locking pin 612 is inserted into the mounting hole 6111d, the raised portion and the recessed portion engage and fit together, and the elastic force of the elastic finger 6111f presses and secures the locking pin 612 in the mounting hole 6111d. In this embodiment, the elastic finger 6111f is provided with the raised portion, and the locking pin 612 is provided with the recessed portion. The positioning protrusion 6112 is provided protrudingly from the third side surface 6111c of the actuator body 6111. The extending direction of the mounting hole 6111d intersects with the extending direction of the positioning protrusion 6112. The portion of the locking pin 612 located outside the mounting hole 6111d forms a locking portion 6122. The locking portion 6122 can engage with one of the at least two engagement slots 711 (e.g., the third engagement slot 711 or the fourth engagement slot 711) to secure the backrest 200 at a specific angular position (e.g., the first angular position or the second angular position).

Furthermore, the mounting portion 710 is located behind the handle coupling 102. Combined with the aforementioned location of the first pivot point 101 at the front lower side of the handle coupling 102, the first pivot point 101 and the mounting portion 710 are located on either side of the handle coupling 102. This creates a better load-bearing structure, effectively distributing the impact force across the baby carrier 1000 in the event of a vehicle collision, making it less susceptible to damage.

As shown in Figures 33 and 34, the operating mechanism 620 includes a second operating member 621, a pulling member 622, a linkage member 623, and an operating reset member 624.

In this embodiment, the second operating member 621 is a handle, which is operably disposed on a side of the backrest body 210 away from the backrest extension portion 230.

There are two linkage members 623, each drivingly connected to the actuators 611 of the locking mechanism 610 on either side. There are two corresponding traction members 622, with each traction member 622 having its ends connected to the second operating member 621 and the corresponding linkage member 623. Both linkage members 623 are movably mounted on the side of the backrest 200 facing away from the passenger compartment. The linkage member 623 comprises a mounting bracket 6231 and a linkage member 6232, which are connected to each other.

The mounting bracket 6231 is generally in the form of a rectangular frame structure and extends in the longitudinal direction of the backrest portion 200. One end of the mounting bracket 6231 is connected to the traction member 622, and the other end is connected to the linkage portion 6232. A receiving space 6231a is formed in the mounting bracket 6231, and the operating reset member 624 is accommodated in the receiving space 6231a. In this embodiment, the operating reset member 624 is a spring. One end of the operating reset member 624 is connected to or abuts the linkage member 623, and the other end of the operating reset member 624 is connected to or abuts the stop member 240 on the backrest portion 200. The operating reset member 624 is suitable for causing the linkage member 623 to drive the second operating member 621 to reset. Specifically, the stopper 240 is also disposed within the accommodating space 6231a. A mounting base 6231b is provided on one side of the mounting bracket 6231 near the linkage portion 6232 (or near the locking mechanism 610). One end of the operating reset member 624 is secured to the mounting base 6231b, and the other end is secured to the stopper 240. Furthermore, a guide 241 is provided on the mounting bracket 6231 or the stopper 240. The operating reset member 624 is sleeved on the guide 241 to prevent displacement during the biasing process. The mounting bracket 6231 includes a first side portion 6231d and a second side portion 6231e disposed opposite each other. A block 6231c is connected approximately in the middle of the first side portion 6231d and the second side portion 6231e to prevent the operating reset member 624 from being removed from the accommodating space 6231a.

As shown in Figure 34 , the linkage portion 6232 also has a generally rectangular structure. The linkage portion 6232 extends in a direction that intersects with the mounting bracket 6231. For example, the linkage portion 6232 and the mounting bracket 6231 may be arranged at a 45-degree angle. The linkage portion 6232 is provided with a slide groove 6233 extending along its direction of extension. In other embodiments, the linkage portion 6232 may not extend in a direction that intersects with the mounting bracket 6231, as long as the slide groove 6233 is arranged in a direction that intersects with the mounting bracket 6231. The positioning protrusion 6112 of the actuator 611 forms a first sliding engagement portion, while the sliding groove 6233 of the linkage 623 forms a second sliding engagement portion. The positioning protrusion 6112 is inserted into and movable along the sliding groove 6233, thereby achieving a sliding engagement between the actuator 611 and the linkage 623.

Furthermore, referring to Figures 32 and 34 , the locking portion 6122 can move toward or away from the mounting portion 710, that is, toward or away from a particular engagement slot 711 (e.g., the third engagement slot 711 or the fourth engagement slot 711). The positioning direction of the slide groove 6233 is inclined relative to the movement direction of the locking portion 6122. Specifically, the slide groove 6233 is inclined upward in a direction approaching the mounting portion 710. In this embodiment, the slide groove 6233 is inclined upward from the inside to the outside.

Specifically, the backrest body 210 includes a backrest board 211 and a cover 212 disposed on the side of the backrest board 211 facing away from the passenger compartment. The backrest board 211 and the cover enclose an installation space. The actuator 611 and at least a portion of the locking pin 612 in the locking mechanism 610, as well as the traction member 622 and the linkage member 623 in the operating mechanism 620, are all mounted within the installation space, thereby enhancing the appearance of the infant carrier and protecting the locking mechanism 610 and the related components of the operating mechanism 620 from damage.

When the second operating member 621 is pulled, the second operating member 621 can pull the linkage member 623 toward the second operating member 621 via the pull member 622, i.e., pull the linkage member 623 upward. The linkage member 623, through the sliding engagement between the guide slot 6233 and the positioning protrusion 6112, drives the actuator 611, thereby causing the locking pin 612 to move away from the mounting portion 710, i.e., away from the corresponding engagement slot 711 (e.g., the third engagement slot 711), until the locking portion 6122 of the locking pin 612 disengages from the corresponding engagement slot 711 (e.g., the third engagement slot 711), and the locking mechanism 610 is in the unlocked state. At this time, the backrest portion 200 can be rotated relative to the housing 110. When the backrest portion 200 is rotated to the desired angular position relative to the housing 110, the locking portion 6122 is opposite to the other engaging groove 711 (such as the fourth engaging groove 711), and the force pulling the second operating member 621 can be removed. At this time, the linkage member 623 can move away from the second operating member 621 under the elastic force of the operating reset member 624, that is, move downward, so that the locking pin 612 moves toward the mounting portion 710 or the other engaging groove 711 (such as the fourth engaging groove 711) until the locking portion 6122 of the locking pin 612 is inserted into the other engaging groove 711 (such as the fourth engaging groove 711). In this way, the backrest portion 200 can adjust its angular position.

In one example, as shown in Figures 36 to 38 , the infant carrier 1000 further includes a mounting plate 700, which is a generally rectangular plate-shaped structure. The mounting plate 700 is fixedly connected to the housing 110. A mounting portion 710 and a retaining rib 720 are provided on either side of the mounting plate 700. Both the mounting portion 710 and the retaining rib 720 protrude toward the passenger compartment. In this embodiment, the mounting plate 700 has two sides, each fixedly connected to the inner sides of two housing side panels 113 of the housing 110. The edges of the two backrest side panels 220, adjacent to the extension 230, i.e., the lower edges of the two backrest side panels 220, form a stop surface 222. The backrest 200 can pivot relative to the housing 110 until the stop surface 222 abuts the limiting rib 720, thereby limiting the pivot angle between the backrest 200 and the housing 110. In this embodiment, the stop surface 222 abuts the limiting rib 720 when the backrest 200 pivots relative to the housing 110 to a position suitable for a baby. This prevents excessive pivoting of the backrest 200 relative to the housing 110, which could pose safety risks or create an uncomfortable riding experience for the baby.

Furthermore, as shown in FIG32 , the mounting portion 710 protrudes toward the backrest portion 200 . The backrest portion 200 is provided with a relief recess 250 corresponding to the mounting portion 710 , thereby allowing the backrest portion 200 to pivot relative to the housing 110 .

Furthermore, as shown in Figures 26 to 28, a sliding hole 231 is provided on the backrest extension 230, and a connecting hole 111 is provided on the portion of the shell body 112 relatively far away from the leg rest portion 150, that is, the portion where the shell body 112 overlaps with the backrest extension 230. One of the sliding hole 231 and the connecting hole 111 is a bar hole and the sliding hole 231 and the connecting hole 111 at least partially overlap. A sliding pin (not shown in the figures) passes through the sliding hole 231 and the connecting hole 111 to guide the backrest 200 to move in the front and rear directions relative to the shell 110. When the backrest portion 200 rotates relative to the housing 110, the backrest extension 230 or the backrest portion 200 is driven to move forward and backward relative to the housing 112. The movement of the backrest extension 230 or the backrest portion 200 is guided by the cooperation of the sliding pin, the sliding hole 231, and the connecting hole 111.

According to the second embodiment of the present invention, the infant carrier 1000 can adjust the infant's sitting position simply by rotating the backrest 200, without requiring the linkage between other components (such as the backrest and legrest), resulting in convenient adjustment and a simple structure.

Furthermore, it should be understood that the backrest element 200 shown in the second embodiment can also be used in the infant carrier of the first embodiment. Accordingly, the backrest extension 230 is provided with a sliding hole 231, and the portion of the housing 110 corresponding to the backrest extension is also provided with a connecting hole. A sliding pin (not shown) passes through the sliding hole 231 and the connecting hole to guide the backrest 200 in forward and backward movement relative to the housing 110. When the backrest portion 200 rotates relative to the housing 110, the backrest extension 230 or the backrest portion 200 is driven to move forward and backward relative to the housing 110. The movement of the backrest extension 230 or the backrest portion 200 is guided by the cooperation of the sliding pin, the sliding hole 231, and the connecting hole.

As shown in Figures 39 and 40 , the structure of the baby carrier 1000 proposed in the third embodiment of the present invention is substantially the same as that of the second embodiment, differing in that the backrest 200 and legrest 150 of the baby carrier 1000 are connected to the front and rear sides of the housing 110, and the legrest 150 is fixedly connected to the housing 110. In this embodiment, the legrest 150 is fixedly connected to the housing 110 using fasteners such as screws. The backrest 200 and the housing 110 are pivotally connected at the fixed first pivot point 101. One of the backrest 200 and the housing 110 may also be provided with a limiting protrusion 260, and the other may be provided with a limiting groove 1300. The limiting protrusion 260 is inserted into the limiting groove 1300. When the backrest 200 pivots relative to the housing 110, the limiting protrusion 260 slides within the limiting groove 1300, thereby guiding the rotation of the backrest 200 and making the rotation more stable. Specifically, the limiting groove 1300 is provided in an arcuate groove on the rear edge of the housing side panel shown. The arcuate groove has a first end 131 and a second end 132. When the pivot angle between the backrest 200 and the housing 110 is at its smallest, meaning the baby carrier 1000 is in a sitting position, the limiting protrusion 260 moves to the first end 131 of the limiting slot 1300, as shown in FIG39 . When the pivot angle between the backrest 200 and the housing 110 is at its largest, meaning the baby carrier 1000 is in a sitting or lying position, the limiting protrusion 260 moves to the second end 132 of the limiting slot 1300, as shown in FIG40 . In this embodiment, the first end 131 is located above and in front of the second end 132. The two backrest side panels 220 of the backrest portion 200 are each provided with a limiting protrusion 260, and the two shell side panels 113 of the shell 110 are correspondingly provided with limiting grooves 1300 that can slideably engage with the two limiting protrusions 260 respectively.

In this embodiment, the location of the first pivot point 101 between the backrest 200 and the housing 110, as well as the location of the engagement slot 711, are similar to those of the second embodiment. In this embodiment, the first pivot point 101 is located at the front lower side of the handle coupling 102, while the mounting portion 710 is positioned behind the handle coupling 102 and at the upper edge of the housing 110 facing the passenger compartment. Specifically, the first pivot point 101 is located in the lower middle portion of the housing side panel 113. The retaining protrusion 260 and the retaining slot 1300 are located at the rear of the housing 110. In this embodiment, both housing side panels 113 are provided with a mating hole 1220 located at the first pivot point 101. Both backrest side panels 220 are provided with a corresponding pivot pin 223 that plugs into and engages with the pivot hole 221, thereby achieving a pivot connection between the housing side panels 113 (or the housing 110) and the backrest side panels 220 (or the backrest portion 200). In this embodiment, the position of the first pivot point 101 is relatively fixed, meaning that the pivot pin 223 can only pivot and cannot move up and down or forward and backward.

As shown in Figures 41 and 42 , the structure of the infant carrier 1000 according to the fourth embodiment of the present invention is substantially similar to that of the third embodiment, differing in that the backrest 200 and the legrest 150 are pivoted at a third pivot point 104, while the legrest 150 and the housing 110 are pivoted at a second pivot point 103. The legrest 150 is rotatable relative to the housing 110 about the second pivot point 103. Specifically, one of the legrest 150 and the housing 110 may be provided with a pivot pin (not shown), and the other may be provided with a pivot hole (not shown). The legrest 150 and the housing 110 are pivoted at the second pivot point 103 through the interlocking engagement of the pivot pin and the pivot hole. The third pivot point 104 is slidable along the height of the housing 110. Specifically, the front sides of the two housing side panels 113 are each provided with a mating hole 1220, which is arranged along the height of the housing 110. The rear sides of the two backrest side panels 220 are respectively pivoted to the legrest portion 150 via two pivot pins 223. Each pivot pin 223 is inserted into a corresponding mating hole 1220 and is movable along the mating hole 1220. As a result, when the legrest 150 rotates relative to the housing 110, it causes the pivoted backrest 200 to pivot backward, and the pivot pin 223 slides within the mating hole 1220 along the height of the housing 110. The location of the third pivot point 104 between the backrest 200 and the legrest 150, as well as the mounting portion 710, in this embodiment are similar to those in the second embodiment. In this embodiment, the third pivot point 104 is located at the lower front side of the handle coupling 102, while the mounting portion 710 is positioned behind the handle coupling 102 and at the upper edge of the housing 110 facing the passenger compartment.

Furthermore, the backrest 200 is movable relative to the housing 110. Specifically, a movable protrusion 270 can be provided on one of the backrest 200 and the housing 110, and a movable slot 140 can be provided on the other. The movable protrusion 270 is inserted into the movable slot 140 and can move along the movable slot 140. When the legrest 150 rotates relative to the housing 110 and the third pivot point 104 between the legrest 150 and the backrest 200 moves in the height direction, the backrest 200 moves forward and backward relative to the housing 110. The provision of the movable protrusion 270 and the movable slot 140 guides this relative movement of the backrest 200 and the housing 110.

The aforementioned adjustment device and infant carrier have at least the following technical advantages: The adjustment device 600 of the infant carrier selectively limits the angular position of the backrest 200 relative to the housing 110 via a locking mechanism 610 disposed between the housing 110 and the backrest 200. Simultaneously, the operating mechanism 620 drives the locking mechanism 610 from a locked state to an unlocked state. This allows the user to adjust the angular position of the backrest 200 simply by operating the operating mechanism 620, without requiring any other operations. Furthermore, the adjustment device 600 can accommodate different infant sitting positions simply by adjusting the angular position of the backrest 200 relative to the housing 110, without requiring the interaction of other components. The device has a simple structure and is easily implemented.
