Detailed Description

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

The embodiment of the present application proposes an infant carrier 1000, and the infant carrier 1000 may be, for example, an infant carrier or an infant seat. In particular, in the present application, the infant carrier 1000 is described below as an infant carrier.

Fig. 1 and 2 schematically show perspective views of an infant carrier (i.e., infant carrier 1000) provided according to a first embodiment of the application, the infant carrier including a seat portion 100, a backrest portion 200, a pivot structure 400 (see fig. 6 and 7), and an adjustment mechanism 500 (see fig. 11 and 12).

Referring to fig. 1-3, in some examples, the seat portion 100 is disposed at an angle to the back portion 200 to form a seating space 300. Wherein the backrest part 200 is used to support the upper body (e.g., head and back) of an infant, and the seat part 100 is used to support the lower body (e.g., buttocks and legs) of an infant. The seat portion 100 may include a housing 110 and a leg rest 150. The backrest 200 is pivotally connected to the housing 110 to form a seating space 300 for carrying an infant. In the present first embodiment, the leg rest 150 is an integrally formed structure with the housing 110. In other embodiments, the leg rest 150 and the housing 110 may be fixedly coupled by screwing, riveting, or welding. The backrest 200 has at least two angular positions relative to the housing 110 to accommodate different seating requirements of infants, such as different angular sitting and lying postures. For example, the first use state of the backrest 200 and the housing 110 in fig. 1 and 3 is suitable for a state in which an infant lies down, and the second use state of the backrest 200 and the housing 110 in fig. 4 and 5 is suitable for a state in which an infant sits down. It should be understood that the angular positions of the backrest 200 and the housing 110 may be more or less than two as desired, and the present application is not limited thereto. Further, it should be understood that the correspondence between the first usage state and the second usage state of the backrest 200 and the housing 110 and the posture of the infant on the infant carrier 1000 is merely exemplary, and does not necessarily correspond to the lying state of the infant and the sitting state of the infant, respectively, for example, the first usage state may be a sitting state suitable for the infant, the second usage state may be a lying state suitable for the infant, and the like, which is not limited by the present application.

In some embodiments, when the backrest 200 of the infant carrier 1000 is adjusted to a lying posture suitable for an infant relative to the housing 110, the angle between the backrest and the horizontal direction is larger than the angle between the leg rest and the horizontal direction, so that the legs of the infant cannot be higher than the head when lying flat, and the comfort of lying flat of the infant is improved.

The seat portion 100 is provided with a locking member 800 at a side facing away from the seating space 300, and the locking member 800 is mainly used for locking with a carrier base on the car seat, so that the infant carrier can be stably fixed on the car seat. Specifically, the engaging member 800 is a rod-shaped structure that is fixedly connected to the bottom of the seat portion 100 by a fastener (screw, bolt, or the like) or is directly integrally formed to the bottom of the seat portion 100.

To facilitate handling of the infant carrier by the user, in some examples, as shown in fig. 1 and 3, the infant carrier further includes a handle 7000, the handle 7000 being connected to the seat portion 100 or the back portion 200. Alternatively, the handle 7000 may be detachably or non-detachably mounted to the seat portion 100 or the backrest portion 200. In the first embodiment, the housing 110 is provided with a handle coupling portion 102 (see fig. 6), and the handle 7000 is detachably pivoted to the handle coupling portion 102 of the seat portion 100. Thus, when the infant carrier is to be carried, the carrying handle 7000 is turned away from the seat portion 100 or the backrest portion 200, so that the user can hold the infant carrier conveniently; when the infant carrier is not required to be carried, the handle 7000 is rotated to be close to the seat part 100 or the backrest part 200, so that the handle 7000 is prevented from blocking the view of the infant, and meanwhile, a user can conveniently put the infant into the infant carrier or hold the infant out of the infant carrier.

In this first embodiment, the seat portion 100 may also be pivotally connected to the backrest portion 200. In other embodiments, the seat portion 100 and the backrest portion 200 may be fixedly connected, i.e., the seat portion 100 and the backrest portion 200 cannot move relative to each other. Specifically, in the 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 is adjustable, so that the infant carrier can have at least two use states. Such as a first use condition as shown in fig. 1 and 3 (in which the infant is in a lying position in the infant carrier), or a second use condition as shown in fig. 4 and 5 (in which the infant is in a sitting position in the infant carrier), etc. Of course, at least one transition state may be provided between the first and second use states. In this way, the user can adaptively adjust the angle between the seat portion 100 and the backrest portion 200 according to the state (e.g., sleep state, awake state) of the infant, so that the comfort of the infant sitting in the infant carrier can be improved.

Referring to fig. 4-7, in some examples, both the backrest portion 200 and the seat portion 100 are pivotally connected by the pivot structure 400. Specifically, the front end of the backrest portion 200 is pivotally connected to the rear end of the seat portion 100 by a pivot structure 400. More specifically, the pivot structure 400 includes a first pivot mating portion, a second pivot mating 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 by a first pivot fitting portion and a second pivot fitting portion. The mating connector pivotally connects the first and second pivotal mating portions.

Specifically, the first pivot fitting portion includes a pivot member 420, the second pivot fitting portion includes a pivot base 430, the pivot base 430 is provided with a first engagement groove 431, the fitting connection member includes a pivot cover 440, the pivot cover 440 is provided with a second engagement groove 441, the first engagement groove 431 and the second engagement groove 441 enclose to form a pivot groove 410, and at least part of the pivot member 420 is inserted into the pivot groove 410 and can rotate in the pivot groove 410, so that the infant carrier 1000 can be switched between a first use state and a second use state. In the present first embodiment, as shown in fig. 6 and 7, the pivot seat 430 is provided at the backrest portion 200, and the pivot member 420 is provided at the seat portion 100.

The "front end" as used herein refers to an end of the seat portion 100 away from the backrest portion 200, and the "rear end" refers to an end of the backrest portion 200 away from the seat portion 100. More specifically, "front end" refers to the end of the infant carrier closer to the infant's feet and "rear end" refers to the end closer to the infant's head. Further, unless specifically stated and limited otherwise, the orientations of the various embodiments of the present application, such as "front", "back", "left", "right", etc., with respect to the infant carrier (i.e., infant carrier 1000) may be represented by arrows F, B, L, R in the figures. These directional terms are used only to make the description of the embodiments of the present application clearer and are not used to unduly limit the scope of the present application.

Referring to fig. 6 to 10, in particular, the pivot cover 440 is detachably mounted on the pivot base 430, for example, the pivot cover 440 is mounted on the pivot base 430 by means of a snap-fit connection; or the pivoting cover 440 is mounted to the pivoting base 430 by means of a screw connection. Specifically, in the first embodiment, as shown in fig. 6 and 8, the pivot base 430 is provided with a first connection hole 432, the pivot cover 440 is provided with a second connection hole 442, and the pivot cover 440 and the pivot base 430 sequentially pass through the second connection hole 442 and the first connection hole 432 by fastening members such as a connection screw or a connection screw.

Referring to fig. 6 to 9, in some examples, the first and second engaging grooves 431 and 441 are arc-shaped grooves. As shown in fig. 6 and 10, the pivoting member 420 has an arc surface 421, and the arc of the arc surface 421 is adapted to the arc of the groove wall of the pivoting groove 410. In this way, the smoothness of the rotation of the pivoting member 420 within the pivoting groove 410 can be improved. Specifically, in the first embodiment, the first engaging groove 431 and the second engaging groove 441 are both semicircular grooves, so that when they are enclosed, a circular pivoting groove 410 can be formed. Of course, in other alternative embodiments, the first engaging groove 431 and the second engaging groove 441 may be other arc grooves, and only the first engaging groove 431 and the second engaging groove 441 may be required to enclose to form the complete circular pivoting groove 410. For example, when the first engaging groove 431 is a 2/3 circular groove, the second engaging groove 441 is a 1/3 circular groove.

In some examples, one of the pivot mount 430 and the pivot member 420 is integrally formed with the seat portion 100 and the other is integrally formed with the backrest portion 200. In other words, when the pivot base 430 is integrally formed on the seat portion 100, the pivot member 420 is integrally formed on the backrest portion 200; when the pivot base 430 is integrally formed on the backrest portion 200, the pivot member 420 is integrally formed on the seat portion 100. Specifically, according to the foregoing, in the present first embodiment, as shown in fig. 8 and 10, the pivot mount 430 is integrally formed to the backrest portion 200, and the pivot member 420 is integrally formed to the seat portion 100. In this way, the structural strength of the pivot structure 400 is improved, thereby improving the reliability of the pivot. Of course, in other alternative embodiments, one of the pivot mount 430 and the pivot member 420 may be removably connected to the seat portion 100 and the other may be removably connected to the back portion 200. Through setting pivot structure 400 and seat portion 100 and back portion 200 integrated into one piece, realized so that the pivot connection between back and the seat need not to set up independent pivot axle and pivot hole to reduce the quantity of spare part, not only simplified the function of lying down, make to adjust more stable, reliable, and the holistic weight of baby carrier lighter.

In the present first embodiment, the pivot mount 430 is located at an end of the back rest portion 200 near the seat portion 100, i.e., a front end of the back rest portion 200. The pivot member 420 is located at an end of the seat portion 100 near the backrest portion 200, i.e., a rear end of the seat portion 100.

Specifically, the pivot seat 430 includes two through-connection portions 433 formed at two sides of the first engaging groove 431, and two of the aforementioned first connecting holes 432 are respectively disposed on the two through-connection portions 433. In the first embodiment, the seat portion 100 is formed with a bracket 120. 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 with the bracket bottom wall 122 at an angle, and the two bracket side walls 123 are connected to the two sides of the bracket body 121 and the bracket bottom wall 122 and are oppositely arranged. The pivot 420 is connected between the two bracket side walls 123. The pivot 420, bracket body 121, bracket bottom wall 122 and two bracket side walls 123 define a through-hole 130 therebetween. The cross-over portion 433 is adapted to be received in the cross-over hole 130 for forming a connection of the backrest portion 200 and the seat portion 100.

Referring to fig. 8 and 10, in the present first embodiment, the infant carrier is provided with two sets of the above-described pivot structures 400, and the two sets of pivot structures 400 are disposed at intervals in the left-right direction of the infant carrier. In this way, the stability of the backrest portion 200 with respect to the seat portion 100 can be improved. Of course, one or more of the above-described pivot structures 400 may be provided as desired, and the present application is not limited thereto.

Referring to fig. 11 to 14, an adjusting mechanism 500 is provided between the seat portion 100 and the backrest portion 200 for adjusting an angle between the seat portion 100 and the backrest portion 200 and enabling the angle therebetween to be kept unchanged. Specifically, the adjustment mechanism 500 includes a locking member 510, a locking member 520, and a first operating member 530. The locking piece 510 is mounted on one of the seat portion 100 and the backrest portion 200, and a locking recess 511 is provided on the locking piece 510. In the first embodiment, the locking member 520 is a lock pin. The locking member 520 is mounted on the other of the seat portion 100 and the backrest portion 200. The locking member 520 is capable of engaging and disengaging with the locking recess 511 to lock and unlock the backrest portion 200 with the seat portion 100. In the present first embodiment, the moving direction of the locking piece 520 is perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200, and the locking piece 520 moves in the direction perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200 to perform locking and unlocking of the seat portion 100 and the backrest portion 200, so that the moving stroke and the path setting of the locking piece 520 can be more flexible. Specifically, the locking member 510 is in a sheet-like structure, and the plane of the locking member 510 is perpendicular to the transverse width direction of the seat portion 100 or the backrest portion 200, and the locking recess 511 and the sliding recess 512 are both provided on the sheet-like locking member, so that the plane of the locking recess 511 and the sliding recess 512 is also perpendicular to the transverse width direction 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 in its path of movement. The first operating member 530 is operatively coupled 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 locking position, the locking member 520 is located in the locking recess 511, and the backrest portion 200 is fixed relative to the seat portion 100, that is, the backrest portion 200 cannot rotate relative to the seat portion 100, so that the infant carrier can be maintained in a specific use state, such as a first use state or a second use state. When the first operating member 530 is in the unlocked position, the locking member 520 is retracted away from the locking recess 511, and the backrest portion 200 is pivotable relative to the seat portion 100, i.e., the angle between the backrest portion 200 and the seat portion 100 can be adjusted. Meanwhile, the locking member 510 is disposed on the seat portion 100 to effectively strengthen the strength of the adjusting mechanism 500. Since the force is greater at the adjustment mechanism 500 of the backrest portion 200 and the seat portion 100 in the event of a collision, the reinforcement of the strength of the adjustment mechanism 500 by the locking member 510 can help to prevent the infant carrier from being deformed in the event of a collision. In the first embodiment, the locking member 510 is attached to the seat portion 100, but the locking member 510 may be integrally formed with the seat portion 100 as long as the function of reinforcing the structural strength thereof is achieved. In addition, the locking member 510 is provided at the upper edge of the seat part 100 or the backrest part 200 to be as far away from the pivot structure 400 as possible; the arrangement makes the integral stress points of the infant carrier disperse, the stress is more uniform, the condition of stress concentration is avoided, and the impact performance of the infant carrier when impacted is ensured.

The structure and the working principle of the adjusting mechanism 500 are simple, and the locking member 520 can enter or withdraw from the locking concave portion 511 only by controlling the position of the first operating member 530, so that the included angle between the seat portion 100 and the backrest portion 200 can be adjusted, and the process is convenient and fast, and the situation such as jamming is not easy to occur, so that the stability of angle adjustment can be effectively improved.

Referring to fig. 13-15, 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, the sliding recess 512 communicates with each locking groove 5111, and the groove wall of the sliding recess 512 and the groove wall of each locking groove 5111 enclose a closed structure. The locking member 520 is movably disposed in the sliding recess 512 and each locking groove 5111. When the first operating member 530 is in the locked position (see fig. 11 and 13), the locking member 520 is positioned in one of the locking grooves 5111, and the backrest portion 200 is fixed with respect to the seat portion 100. When the locking members 520 are located in each locking groove 5111 one by one, the angle between the backrest portion 200 and the seat portion 100 is different, i.e. corresponds to the baby carrier presenting different backrest angle states. When the first operating member 530 is in the unlocked position (see fig. 14), the locking member 520 is located in the sliding recess 512 and the backrest portion 200 can pivot relative to the seat portion 100.

Specifically, in the present first embodiment, as shown in fig. 15, 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 communicates with the first locking groove 5111A and the second locking groove 5111B. Thus, the lock 520 is considered to be movably inserted in the slide recess 512, the first locking groove 5111A, and the second locking groove 5111B. Specifically, when the first operating member 530 is in the locking position, the locking member 520 may be located in the first locking groove 5111A or the second locking groove 5111B. More specifically, when the locking member 520 is positioned in the first locking groove 5111A, the seat portion 100 and the backrest portion 200 are at the first included angle, and the infant carrier 1000 is in the first use state. When the locking member 520 is located in the second locking groove 5111B, the seat portion 100 and the backrest portion 200 are located at a second included angle, the first included angle is greater than the second included angle, and the infant carrier 1000 is in the second use state. In the present first embodiment, as shown in fig. 11 and 13, when the locking piece 520 is located in the first locking groove 5111A, the infant carrier is in the first use state, and at this time, the angle between the backrest portion 200 and the seat portion 100 is referred to as a first angle; when the locking member 520 is located in the second locking groove 5111B, the infant carrier is in the first use state, and at this time, the angle between the backrest portion 200 and the seat portion 100 is referred to as a second angle; wherein, the first contained angle is greater than the second contained angle.

Referring to fig. 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 and second locking grooves a and B may be regarded as transition grooves 5111C. Such a transition groove 5111C is located between the first locking groove 5111A and the second locking groove 5111B and communicates with both of the slide concave portions 512. For example, in the present first embodiment, the locking grooves 5111 are three, including a first locking groove 5111A, a second locking groove 5111B, and a transition groove 5111C, respectively, the transition groove 5111C being located between the first locking groove 5111A and the second locking groove 5111B. In other embodiments, the locking grooves 5111 may also be, for example, four, including a first locking groove 5111A, a second locking groove 5111B, and two transition grooves 5111C, respectively. Both transition grooves 5111C are located between the first locking groove 5111A and the second locking groove 5111B. When the locking member 520 is located in such a transition groove 5111C, a third included angle is formed between the seat portion 100 and the backrest portion 200, and the third included angle is greater than the second included angle and less than the first included angle. The infant carrier is in a transition state between the first use state and the second use state, that is, when the infant carrier is in the transition state, the included angle between the backrest portion 200 and the seat portion 100 is between the first included angle and the second included angle. Specifically, the more the number of transition grooves 5111C is, the smaller the adjustment interval of the included angle between the backrest portion 200 and the seat portion 100 is, the more precisely the user can adjust the included angle between the backrest portion 200 and the seat portion 100, so that the state of the infant carrier meets the riding requirement of the infant more and the comfort is higher.

Referring to fig. 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, i.e., the locking recess 511 is closer to the pivot structure 400 (or the rotation axis X1-X1 between the seat portion 100 and the backrest portion 200) than the sliding recess 512. When it is desired to adjust the angle between the seat portion 100 and the backrest portion 200, it is desired to move the locking member 520 up the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C into the locking recess 511. When it is desired to lock the angle between the seat portion 100 and the backrest portion 200, it is desired to move the locking member 520 downward from the locking concave portion 511 into the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C.

In some examples, the respective locking grooves 5111 (i.e., the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C) are disposed at intervals about the circumferential direction of the rotational axis X1-X1 between the seat portion 100 and the back portion 200. It should be noted that the rotation axes X1-X1 are rotation axes of the pivoting member 420 pivoting in the pivoting slot 410. The sliding recess 512 has a circular arc structure, and the arc center of the sliding recess 512 is located on the rotation axis X1-X1. In this way, when the locking piece 520 is withdrawn from the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C to the sliding recess 512, the locking piece 520 can be moved within the sliding recess 512 by rotating the backrest 200.

In the present first embodiment, as shown in fig. 15, since the circular arc of the slide concave portion 512 is short, the slide concave portion 512 is approximately linear. In other embodiments, the sliding recess 512 may be provided in a linear shape, so long as the sliding of the locking member 520 in the sliding recess 512 is not blocked by the respective locking grooves 5111A, 5111C, 5111B.

In some examples, the first operating member 530 can be operatively connected directly to the locking member 520. Of course, in other alternative embodiments, the first operating member 530 may be indirectly operatively coupled to the locking member 520. For example, as shown in fig. 13 and 14, the adjustment mechanism 500 may further include a slide transmission member 540, and the first operating member 530 is operatively connected to the locking member 520 through the slide transmission member 540. Specifically, the slide transmission 540 is provided with a connection portion 541 and a transmission portion 542. The lock 520 is provided in the connection portion 541, and the transmission portion 542 is provided with a guide groove 543, and the guide groove 543 extends obliquely with respect to the moving direction (first direction F1) of the first operation member 530. More specifically, in the present first embodiment, as shown in fig. 11 to 14, a lock 510 is mounted to the seat portion 100. The first operating member 530 is movably mounted on the back portion 200 and has a driving portion 531, and 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 along the second direction F2 relative to the locking member 510, so that the locking member 520 is switched between the sliding recess 512 and the locking recess 511. In the first embodiment, the moving direction (i.e., the first direction F1) of the first operation member 530 is the same as the extending direction of the backrest portion 200 in the front-rear direction, and the first direction F1 is perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200. The moving direction (i.e., the second direction F2) of the slide transmission member 540 and the locking member 520 is perpendicular to both the first direction F1 and the lateral width direction of the seat portion 100 or the backrest portion 200. The locking piece 520 in the conventional infant carrier is mostly moved in the lateral width direction of the seat part 100 or the backrest part 200 to perform locking and unlocking of the seat part 100 and the backrest part 200, whereas the locking piece 520 in the first embodiment is moved in a direction perpendicular to the lateral width direction of the seat part 100 or the backrest part 200 to perform locking and unlocking of the seat part 100 and the backrest part 200, so that the movement stroke and path of the locking piece 520 can be set more flexibly.

Referring to fig. 11 and 16, in some examples, the driving portion 531 includes a latch 5311 and a pulling block 5312. The pulling block 5312 has a U-shaped structure and a first clamping cavity 5313, the first clamping cavity 5313 is used for clamping the transmission portion 542 of the sliding transmission member 540, and the bolt 5311 sequentially passes through one side wall of the first clamping cavity 5313 and the guide groove 543 and then is connected with the other side wall of the first clamping cavity 5313. In this way, the latch 5311 is not easy to disengage from the guide groove 543 when sliding in the guide groove 543, and the stability of the driving connection between the first operating member 530 and the sliding transmission member 540 is improved.

Referring to fig. 2, 13 and 14, in some examples, the first operating member 530 also has an operating portion 532. The operation portion 532 is located at a side of the backrest portion 200 facing away from the seating space 300 and at a rear end of the backrest portion 200. The operation portion 532 is exposed through the operation hole 201 of the backrest portion 200 so as to be operated and connected to the driving portion 531. In this way, the user can directly control the first operation piece 530 to switch between the lock position and the unlock position by the operation portion 532, and further control the sliding of the driving portion 531 in the guide groove 543.

Referring to fig. 13, 14, and 17, in some examples, the guide slot 543 has oppositely disposed first and second slot ends 5431 and 5432. Specifically, the first slot end 5431 is closer to the locking member 510 than the second slot end 5432, and the second slot end 5432 is closer to the operating portion 532 than the first slot end 5431 in the moving direction (first direction F1) of the first operating member 530. More specifically, when the first operating member 530 is in the locked position (see fig. 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 fig. 14), the driving portion 531 is located at the second slot end 5432. Specifically, when the user pulls the operation portion 532 to move the driving portion 531 from the first slot end 5431 to the second slot end 5432, the driving portion 531 may drive the sliding transmission member 540 to move upward along the guiding direction of the locking slot 5111 (the first locking slot 5111A or the second locking slot 5111B or the transition slot 5111C) relative to the locking member 510, and may further drive the locking member 520 to move from the locking slot 5111 to the sliding recess 512, so that the locking member 520 is not limited by the locking slot 5111, and the locking member 520 may move in the circumferential direction of the rotation axis X1-X1 within the sliding recess 512, so that when the first operation member 530 is in the unlocking position, i.e., when the locking member 520 moves to the sliding recess 512, the user may adjust the state of the infant carrier by pushing the backrest 200 to rotate about the rotation axis X1-X1.

Referring to fig. 11, in some examples, the locking member 510, when mounted on the inner wall of the seat portion 100, leaves a gap with the inner wall. The connecting portion 541 of the sliding transmission member 540 has a U-shaped structure and has a second holding cavity 544, where the second holding cavity 544 is used to hold the locking member 510, and the locking member 520 sequentially passes through one side wall of the second holding cavity 544, the locking recess 511 or the sliding recess 512 of the locking member 510, and then is connected to the other side wall of the second holding cavity 544. In this way, the locking member 520 is prevented from being separated from the locking recess 511 or the sliding recess 512 during the movement, and the stability of the angle adjustment of the infant carrier is improved.

In the present first embodiment, as shown in fig. 11 and 12, the locking member 520 is connected with the connection portion 541 of the slide transmission member 540 through the latch 570. Specifically, the locking member 520 is connected to the latch 570 after passing through the through hole 5441 (see fig. 17) on the side wall of the second holding cavity 544, and the size (specifically, the length L1) of the latch 570 is larger than the diameter of the through hole 5441, so that the latch 570 can abut against the edge of the through hole 5441 to prevent the locking member 520 from being separated from the connecting portion 541 from the through hole 5441.

Referring to fig. 11 and 12, in some examples, the adjustment mechanism 500 may also include a mounting bracket 550. Alternatively, the mounting bracket 550 is fixedly mounted to the backrest portion 200, or the mounting bracket 550 is detachably mounted to the backrest portion 200. As shown in fig. 12 and 18, the mounting bracket 550 is provided with a bar-shaped slide groove 551, and the bar-shaped slide groove 551 extends from the locking recess 511 toward the slide recess 512. As shown in fig. 12 and 13, the locking piece 520 passes through the bar-shaped slide groove 551, the connecting portion 541, and is movably inserted in the slide recess 512 or the locking recess 511. Further, the size (specifically, the length L1) of the latch 570 is greater than the width L2 of the bar-shaped sliding groove 551, so that the locking member 520 is prevented from being separated from the bar-shaped sliding groove 551 during the moving process. When the locking member 520 moves to the sliding recess 512, the user pushes the backrest 200 to rotate the mounting frame 500 along with the backrest 200 around the rotation axis X1-X1, and at the same time, the mounting frame 500 pushes the locking member 520 to rotate in the locking recess 511 around the rotation axis X1-X1, so as to change the included angle between the backrest 200 and the seat 100.

Referring again to fig. 11 and 12, in some examples, the adjustment mechanism 500 may also include a reset member 560. The return member 560 abuts between the mounting bracket 550 and the slide transmission member 540, and the return member 560 is configured to drive the slide transmission member 540 to return so that the lock member 520 moves from the slide recess 512 to the lock recess 511 (the first lock groove 5111A or the second lock groove 5111B or the transition groove 5111C). In particular, return member 560 may be a spring or other type of resilient member. In the present first embodiment, the return member 560 is a spring. As shown in fig. 17, a third catching cavity 545 is formed on the sliding transmission member 540. As shown in fig. 12 and 13, the spring is accommodated in the third clamping cavity 545, one end of the spring is abutted against the bottom wall of the third clamping cavity 545, and the other end is abutted against the mounting frame 550, so that the spring can be prevented from being offset in the compression or resetting process. More specifically, the third clamping cavity 545 further includes a limiting boss 546, and the spring is sleeved on the limiting boss 546, so that the spring can be further prevented from being biased.

The operation of the adjustment of the infant carrier condition (angle between the backrest portion 200 and the seat portion 100) will be described below with reference to fig. 6, 7 and 12 to 14.

As shown in fig. 13, when the locking piece 520 is located in the first locking groove 5111A, the groove wall of the first locking groove 5111A can restrict the locking piece 520 from moving into the other locking groove 5111, and thus the backrest part 200 can be restricted from pivoting relative to the seat part 100, thereby allowing the infant carrier to be maintained in a lying state.

As shown in fig. 14, when the user needs to adjust the state of the infant carrier, that is, needs to switch the infant carrier from the lying state to the transitional state or from the sitting state, the user may pull the operation portion 532 upward along the first direction F1, so that the operation portion 532 drives the driving portion 531 to move upward along the first direction F1. When the operation portion 532 moves upward along the first direction F1, the driving portion 531 drives the sliding transmission member 540 and the locking member 520 to move upward along the second direction F2 relative to the locking member 510 under the action of the guiding groove 543, so that the locking member 520 is retracted from the first locking groove 5111A into the sliding recess 512, and the resetting member 560 is compressed. When the locking member 520 moves into the sliding recess 512, the backrest portion 200 is pushed to rotate the backrest portion 200 around the rotation axis X1-X1 relative to the seat portion 100, and at the same time, the mounting bracket 550 rotates with the backrest portion 200 and pushes the locking member 520 to move around the rotation axis X1-X1 in the sliding recess 512. When the locking member 520 moves directly above the transition groove 5111C or the second locking groove 5111B, the user can release the operating portion 532, and at this time, the return member 560 returns, and the return member 560 pushes the slide transmission member 540 downward in the opposite direction of the second direction F2, so that the locking member 520 can enter the transition groove 5111C or the second locking groove 5111B from the slide concave portion 512. Specifically, during the downward movement of the sliding transmission member 540 in the opposite direction of the second direction F2, the driving portion 531 may be moved downward in the opposite direction of the first direction F1 by the guide groove 543, so that the operating portion 532 is reset, and the first operating member 530 is located at the locking position.

In some examples, the adjustment mechanism 500 may be provided with one or more. Specifically, in the present first embodiment, two adjustment mechanisms 500 are provided, and the two adjustment mechanisms 500 are disposed at intervals in the left-right direction of the infant carrier. In some examples, the first operating members 530 of each adjusting mechanism 500 are arranged in parallel, and the operating portions 532 of each first operating member 530 are independent of each other, so that when the state of the infant carrier needs to be adjusted, two operating portions 532 can be simultaneously operated. In the first embodiment, as shown in fig. 16, each of the first operation members 530 shares one operation portion 532, that is, the driving portion 531 corresponding to each of the first operation members 530 is manipulated by the same operation portion 532. Thus, the two driving portions 531 and thus the two slide drivers 540 and the two stoppers 520 can be simultaneously controlled by the operating portion 532.

The infant carrier and the adjustment mechanism 500 thereof according to the first embodiment of the present application have at least the following technical effects:

The above-mentioned adjusting mechanism 500 is disposed between the seat portion 100 and the backrest portion 200 for adjusting an included angle therebetween, wherein 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. Since the locking member 520 is movably disposed on the locking member 510, the first operating member 530 is operatively coupled to the locking member 520, and thus, 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 the moving path thereof, when the first operating member 530 is located at the locking position, the locking member 520 is retained in the locking recess 511 of the locking member 510, so that the backrest portion 200 can be fixed relative to the seat portion 100 such that the angle therebetween remains unchanged; when the first operating member 530 moves to the unlocking position, the first operating member 530 drives the locking member 520 to retract from the locking recess 511, so that the backrest portion 200 can pivot relative to the seat portion 100 to adjust the angle therebetween. The structure and the working principle of the adjusting mechanism 500 are simple, and the locking member 520 can enter or withdraw from the locking concave portion 511 only by controlling the position of the first operating member 530, so that the included angle between the seat portion 100 and the backrest portion 200 can be adjusted, and the process is convenient and fast, and the situation such as jamming is not easy to occur, so that the stability of angle adjustment can be effectively improved.

As shown in fig. 19 to 21, a second embodiment of the present application provides an infant carrier 1000. Similar to the infant carrier of the first embodiment, the infant carrier of the second embodiment of the application also includes a seat portion 100 and a backrest portion 200. Unlike the first embodiment, in the infant carrier of the second embodiment, the backrest portion 200 and the seat portion 100 are pivotally connected to the fixed first pivot point 101, and the infant carrier of the second embodiment further includes an adjustment mechanism disposed between the backrest portion 200 and the seat portion 100 to enable the backrest portion 200 to be switched between at least two angular positions relative to the seat portion 100. In this second embodiment, for the purpose of description different from the first embodiment, the adjusting mechanism is referred to as an adjusting device 600. In other words, the adjustment device 600 is a modification of the adjustment mechanism 500.

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

The backrest 200 has at least two angular positions relative to the housing 110 to accommodate different seating requirements of an infant. For example, the first angular position of the backrest 200 and the housing 110 in fig. 19 is suitable for a sitting posture of an infant, the third angular position of the backrest 200 and the housing 110 in fig. 20 is suitable for a reclining posture of an infant, the second angular position of the backrest 200 and the housing 110 in fig. 21 is suitable for a lying posture of an infant, and so on. It should be understood that the angular positions of the backrest 200 and the housing 110 may be set to more than three or less than three as desired, and the present application is not limited thereto. Furthermore, it should be understood that the correspondence between the first angular position, the second angular position, and the third angular position of the backrest 200 and the housing 110 and the posture of the infant on the infant carrier 1000 is merely exemplary, and does not necessarily correspond to the sitting posture of the infant, the lying posture of the infant, and the reclining posture of the infant, respectively, and the first angular position may be a lying posture suitable for the infant, the second angular position may be a reclining posture suitable for the infant, the third angular position may be a sitting posture suitable for the infant, and the like, which is not limited in the present application.

As shown in fig. 22 to 24, the housing 110 is provided with a handle coupling portion 102, and the handle coupling portion 102 is used to couple with the handle 7000 of the infant carrier 1000. The direction in which the infant is seated on the infant carrier 1000 is the front direction, and the direction from the bottom edge of the case 110 to the handle coupling portion 102 is the upper direction. The first pivot point 101 is located in front of the handle joint 102, which is beneficial to the crash stress performance of the infant carrier 1000. Further, the first pivot point 101 is located near the lower position, which is beneficial to lowering the center of gravity of the infant riding on the infant carrier 1000 and improving the safety of the infant riding. Fig. 19 to 24 and the subsequent drawings still show the front side by arrow "F", the rear side by arrow "B", the upper side by arrow "U", and the lower side by arrow "D". The arrow "F" indicates a direction in which the infant is seated on the infant carrier 1000.

Fig. 25 and 26 show a schematic perspective view of the infant carrier 1000 in the present embodiment. The first angular position of the backrest 200 and the housing 110 of the infant carrier 1000 shown in fig. 25 is suitable for sitting postures of infants, and the second angular position of the backrest 200 and the housing 110 of the infant carrier 1000 shown in fig. 26 is suitable for lying postures of infants. Specifically, referring to fig. 27 together, the backrest portion 200 includes a backrest body 210, backrest side plates 220 connected to both sides of the backrest body 210, and a backrest extension 230 connected to the underside of the backrest body 210. When the backrest 200 is pivoted to the housing 110, the backrest extension 230 is located on the side of the housing 110 facing the seating space. The side of the backrest body 210 far away from the backrest extension 230 is provided with a headrest 280 for supporting the head of an infant, and the headrest 280 is slidably connected with the backrest body 210, so that the installation position of the headrest 280 relative to the backrest body 210 can be adjusted according to the body shape of the infant. Referring to fig. 28, the housing 110 is an integrally formed structure, and generally includes a housing body 112 and housing side plates 113 connected to two sides of the housing body 112. The leg rest 150 is fixed to a side of the case body 112 remote from the backrest extension 230 for supporting the legs of the infant. In this embodiment, the leg rest 150 and the housing body 112 are integrally formed.

As shown in fig. 29, two backrest side plates 220 of the backrest 200 are respectively pivoted to two shell side plates 113 of the shell 110. Fig. 30 is an enlarged view at a of fig. 29, showing a specific pivot structure of one of the back side plates 220 and the corresponding shell side plate 113. At least the lower end portion of the backrest side plate 220 is located inside the corresponding case side plate 113. The lower end of the backrest side plate 220 is provided with a pivoting hole 221, the inner side of the shell side plate 113 is provided with a pivoting protrusion 1210, the pivoting protrusion 1210 is provided with a pivoting groove (not shown in the drawing), and a pivoting shaft (not shown in the drawing) passes through the pivoting hole 221 and the pivoting groove on the pivoting protrusion 1210 to realize the pivoting of the backrest side plate 220 and the corresponding shell side plate 113. In other embodiments, the positions of the pivot hole 221 and the pivot protrusion 1210 may be interchanged. Or the back side plate 220 and the corresponding shell side plate 113 may be pivotally connected by other structures.

As shown in fig. 31, the adjustment device 600 includes a locking mechanism 610 and an operating mechanism 620.

The locking mechanism 610 is provided between the housing 110 and the backrest 200, and the locking mechanism 610 has a locked state in which the backrest 200 is fixed at one of at least two angular positions (e.g., a first angular position or a second angular position) and a released state in which the backrest 200 is allowed to be switched between at least two angular positions (e.g., the first angular position and the second angular position).

In this embodiment, as shown in fig. 31, the back side plate 220 and the shell side plate 113 on both sides of the infant carrier 1000 are provided with a locking mechanism 610 so as to achieve smooth adjustment of the angular position of the back portion 200. Fig. 32 is an enlarged view at B of fig. 31, showing a specific structure of the locking mechanism 610 on one side thereof. At the upper edge of the side of the housing 110 facing the seating space, there are provided mounting portions 710 described below, and the mounting portions 710 are 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 arrangement direction of at least two engagement grooves 711 is staggered with the front-rear direction. Referring to fig. 32 to 35, the locking mechanism 610 includes an actuating member 611 and a locking pin 612. The actuating member 611 includes an actuating body 6111 and a positioning protrusion 6112 protruding from one side of the actuating body 6111. In this embodiment, the actuating member 611 is an integrally formed structure. In other embodiments, the actuating member 611 may be connected by welding or riveting the actuating body 6111 and the positioning tab 6112. The actuation body 6111 is generally rectangular in configuration, with the actuation body 6111 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 actuation body 6111 is provided with a mounting hole 6111d, and one end of the locking pin 612 is inserted into the mounting hole 6111 d. The second side 6111b of the actuation body 6111 is provided with a generally rectangular mounting slot 6111e, with the mounting slot 6111e communicating with the mounting hole 6111 d. In this embodiment, the mounting groove 6111e is a rectangular groove, and one side groove wall of the rectangular groove is connected with an elastic finger 6111f. One of the locking pin 612 and the elastic finger 6111f is provided with a convex portion (not shown in the drawing), and the other is provided with a concave portion (not shown in the drawing). When the locking pin 612 is inserted into the mounting hole 6111d, the protruding portion and the recessed portion are inserted and matched, and the locking pin 612 is pressed and fixed in the mounting hole 6111d by the elastic force of the elastic finger 6111f. In this embodiment, the elastic finger 6111f is provided with a convex portion, and the locking pin 612 is provided with a concave portion. The positioning protrusion 6112 protrudes from the third side 6111c of the actuation body 6111. The extending direction of the mounting hole 6111d is staggered 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 portion 200 at an angular position (e.g., the first angular position or the second angular position).

Further, the mounting portion 710 is located rearward of the handle coupling portion 102. In the above, the first pivot point 101 is located at the front lower side of the handle joint 102, that is, the first pivot point 101 and the mounting portion 710 are located at two sides of the handle joint 102. In this way, a better stress structure is formed, and when the vehicle collides, the impact force is favorably dispersed on the infant carrier 1000, so that the infant carrier 1000 is less prone to damage.

As shown in fig. 33 and 34, the operating mechanism 620 includes a second operating member 621, a traction member 622, a linkage member 623, and an operation resetting member 624.

In this embodiment, the second operating element 621 is a handle, and is operatively disposed on a side of the backrest body 210 away from the backrest extension 230.

There are two linkages 623 that are each drivingly connected to the actuation members 611 of the locking mechanism 610 on either side. There are two traction members 622, and both ends of each traction member 622 are connected to the second operation member 621 and the corresponding side linkage member 623, respectively. Both the link members 623 are movably provided on a side of the backrest portion 200 facing away from the seating space. The linkage 623 includes a mounting bracket 6231 and a linkage portion 6232 connected to each other.

The mounting bracket 6231 has a substantially 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 6232. The mounting bracket 6231 has a receiving space 6231a formed therein, and the operation resetting member 624 is received in the receiving space 6231a. In this embodiment, the operation restoring member 624 is a spring. One end of the operation resetting piece 624 is connected or abutted with the linkage piece 623, and the other end of the operation resetting piece 624 is connected or abutted with the stop piece 240 on the backrest part 200, and the operation resetting piece 624 is suitable for enabling the linkage piece 623 to drive the second operation piece 621 to reset. In one embodiment, the stopper 240 is also disposed within the accommodation space 6231a. The mounting bracket 6231 is provided with a mounting base portion 6231b on a side close to the linkage portion 6232 (or close to the lock mechanism 610), and the operation resetting piece 624 is fixed at one end to the mounting base portion 6231b and at the other end to the stopper 240. Further, a guide 241 is further provided on the mounting bracket 6231 or the stopper 240, and the operation resetting piece 624 is sleeved on the guide 241 to prevent the operation resetting piece 624 from being displaced during the biasing process. The mounting bracket 6231 includes a first side portion 6231d and a second side portion 6231e disposed opposite to each other, and a stopper 6231c is attached to substantially the middle of the first side portion 6231d and substantially the middle of the second side portion 6231e to prevent the operation resetting piece 624 from coming out of the accommodation space 6231a.

As shown in fig. 34, the linkage portion 6232 is also substantially rectangular, and the extending direction of the linkage portion 6232 and the extending direction of the mounting bracket 6231 are staggered, for example, the extending direction of the linkage portion 6232 and the extending direction of the mounting bracket 6231 may be disposed at an angle of 45 degrees. The linkage portion 6232 is provided with a chute 6233 extending in the extending direction thereof. In other embodiments, the extending direction of the linkage portion 6232 may not be staggered with the extending direction of the mounting bracket 6231, so long as the setting direction of the sliding groove 6233 is staggered with the extending direction of the mounting bracket 6231. The positioning protrusion 6112 of the actuating element 611 forms a first sliding fit portion, the sliding groove 6233 of the linkage element 623 forms a second sliding fit portion, and the positioning protrusion 6112 is inserted into the sliding groove 6233 and can move along the sliding groove 6233, thereby realizing the sliding fit of the actuating element 611 and the linkage element 623.

Further, with reference to fig. 32 and 34, the locking portion 6122 can be moved in a direction approaching or moving away from the mounting portion 710, i.e., in a direction approaching or moving away from a certain engagement groove 711 (e.g., the third engagement groove 711 or the fourth engagement groove 711). The direction of the sliding groove 6233 is inclined with respect to the moving direction of the locking portion 6122. Specifically, the sliding groove 6233 is inclined upward in a direction approaching the mounting portion 710, that is, the sliding groove 6233 is inclined upward in a direction from the inside to the outside in this embodiment.

Specifically, the backrest body 210 includes a backrest plate 211 and a cover 212 covering a surface of the backrest plate 211 facing away from the seating space. The back plate 211 and the cover enclose an installation space. The actuating member 611 and at least part of the locking pin 612 in the locking mechanism 610, the traction member 622 and the linkage member 623 in the operating mechanism 620 are all mounted in the mounting space, thereby making the appearance of the infant carrier more neat and protecting the relevant components of the locking mechanism 610 and the operating mechanism 620 from being easily damaged.

When the second operating member 621 is pulled, the second operating member 621 can move in a direction approaching the second operating member 621 by pulling the linking member 623 by the pulling member 622, i.e., pulling the linking member 623 upward, and the linking member 623 drives the actuating member 611 to drive the locking pin 612 to move in a direction away from the mounting portion 710 by the sliding engagement between the sliding groove 6233 and the positioning protrusion 6112, i.e., in a direction away from the corresponding engaging groove 711 (e.g., the third engaging groove 711), until the locking portion 6122 of the locking pin 612 is disengaged from the corresponding engaging groove 711 (e.g., the third engaging groove 711), and the locking mechanism 610 is in the unlocking state. At this time, the backrest 200 can be rotated relative to the housing 110, when the backrest 200 is rotated to a desired angle relative to the housing 110, the locking portion 6122 is opposite to the other engaging groove 711 (e.g., 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 be moved away from the second operating member 621, i.e., moved downward, under the elastic force of the operating reset member 624, such that the locking pin 612 is moved in a direction approaching the mounting portion 710 or the other engaging groove 711 (e.g., the fourth engaging groove 711), until the locking portion 6122 of the locking pin 612 is inserted into the other engaging groove 711 (e.g., the fourth engaging groove 711). Thus, the backrest 200 is adjusted in angular position.

In one example, as shown in fig. 36 to 38, the infant carrier 1000 further includes a mounting plate 700 having a substantially rectangular plate-like structure, the mounting plate 700 is fixedly connected to the housing 110, and both sides of the mounting plate 700 are provided with a mounting portion 710 and a limiting rib 720, respectively. The mounting portion 710 and the stopper rib 720 each protrude toward the seating space. In this embodiment, the mounting plate 700 has two and is fixedly connected to the inner sides of the two shell side plates 113 of the shell 110, respectively. The edges of the two back side plates 220 that are adjacent to the back extension 230, i.e., the lower side edges of the two back side plates 220, form the stop surfaces 222. The backrest 200 can pivot relative to the housing 110 until the stop surface 222 abuts the stop rib 720 to limit the pivot angle between the backrest 200 and the housing 110. In this embodiment, the stop surface 222 abuts against the stop rib 720 when the backrest 200 is pivoted relative to the housing 110 to a sitting position suitable for infants. In this way, excessive pivoting of the backrest 200 relative to the housing 110 can be prevented, which may create a safety hazard or uncomfortable riding experience for the seated infant.

Further, as shown in fig. 32, the mounting portion 710 protrudes toward the back portion 200, and the back portion 200 is provided with a relief recess 250 corresponding to the mounting portion 710 to allow the back portion 200 to pivot with respect to the housing 110.

Further, as shown in fig. 26 to 28, the backrest extension 230 is provided with a sliding hole 231, a portion of the case body 112 relatively far from the leg rest 150, that is, a portion of the case body 112 overlapped with the backrest extension 230 is provided with a connection hole 111, one of the sliding hole 231 and the connection hole 111 is a bar-shaped hole and the sliding hole 231 and the connection hole 111 are at least partially overlapped, and a sliding pin (not shown in the drawings) passes through the sliding hole 231 and the connection hole 111 to guide the movement of the backrest 200 in the front-rear direction with respect to the case 110. When the backrest 200 rotates relative to the housing 110, the backrest extension 230 or the backrest 200 is driven to move relative to the housing body 112 in the front-rear direction of the infant carrier 1000, and the movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231 and the connecting hole 111.

According to the infant carrier 1000 of the second embodiment of the present application, the purpose of adjusting to adapt to the sitting posture of the infant can be achieved only by rotating the backrest portion 200, and the linkage between other components (such as the backrest portion and the leg rest portion) is not involved, so that the adjustment is convenient and the structure is simple.

Furthermore, it should be appreciated that the backrest assembly 200 shown in the second embodiment is also applicable to the infant carrier of the first embodiment. Accordingly, the backrest extension 230 is provided with a sliding hole 231, and a portion of the housing 110 corresponding to the backrest extension is also provided with a connection hole. A sliding pin (not shown in the drawings) passes through the sliding hole 231 and the connection hole to guide the backrest 200 to move in the front-rear direction with respect to the housing 110. When the backrest 200 rotates relative to the housing 110, the backrest extension 230 or the backrest 200 is driven to move relative to the housing 110 in the front-rear direction of the infant carrier 1000, and the movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231 and the connecting hole.

As shown in fig. 39 and 40, the structure of the infant carrier 1000 according to the third embodiment of the present application is substantially the same as that of the second embodiment, except that the backrest 200 and the leg rest 150 of the infant carrier 1000 are connected to the front and rear sides of the housing 110, and the leg rest 150 is fixedly connected to the housing 110. In this embodiment, the leg rest 150 is fixedly coupled to the housing 110 by fasteners such as screws. The backrest 200 is pivotally connected to the housing 110 at a fixed first pivot point 101. One of the backrest 200 and the housing 110 may further be provided with a limit protrusion 260, the other one is provided with a limit groove 1300, the limit protrusion 260 is inserted into the limit groove 1300, and when the backrest 200 pivots relative to the housing 110, the limit protrusion 260 slides in the limit groove 1300, thereby guiding the rotation stroke of the backrest 200, and making the rotation smoother. Specifically, the limiting slot 1300 is disposed in an arcuate slot in the rear edge of the illustrated shell side plate, the arcuate slot having a first end 131 and a second end 132. When the pivot angle between the backrest 200 and the housing 110 is minimized, i.e. the infant carrier 1000 is suitable for the sitting posture of the infant, the limit protrusion 260 moves to the first end 131 of the limit slot 1300, as shown in fig. 39. When the pivot angle between the backrest 200 and the housing 110 is the largest, i.e. the infant carrier 1000 is suitable for the infant sitting and lying state, the limit protrusion 260 moves to the second end 132 of the limit slot 1300, as shown in fig. 40. In this embodiment, the first end 131 is located above and in front of the second end 132. The two back side plates 220 of the back portion 200 are respectively provided with a limit protrusion 260, and the two shell side plates 113 of the shell 110 are correspondingly provided with limit grooves 1300 which can be respectively in sliding fit with the two limit protrusions 260.
