Technical Field

The invention relates to the field of children products, in particular to a baby carriage.

Background

The owner of a conventional baby carriage is provided with a baby seat and is pushed by an adult. When a baby is seated in the stroller, the adult is usually positioned behind the stroller seat. Therefore, when the baby carriage is pushed, the front of the baby cannot be seen. In addition, when the baby is on the seat, the safety can be increased if the person can see the baby. In response to the above needs, manufacturers have introduced strollers having a forward and rearward use, which primarily allow the stroller seat to be mounted in both a forward and rearward use position on the frame. When the infant seat is used in the backward direction, it is desirable to adjust the height of the infant seat as high as possible to make the parent more close to the infant, but when the infant seat is used in the forward direction, it is difficult to pass the stability test of the platform if the infant seat is adjusted too high, and therefore the height of the infant seat in the forward direction is limited due to safety considerations. However, the current infant does not limit the height of the infant seat relative to the frame in accordance with its forward use on the frame.

Preferably, the connecting seat 31 is further mounted on the frame 10, the engaging seat 32 is movably mounted on the carrier 20, accordingly, the engaging seat has at least a first adjusting position X and a second adjusting position Y above the first adjusting position X relative to the carrier 20, and the carrier 20 is provided with the first positioning portion 11 for keeping the engaging seat 32 at the second adjusting position Y, so that the carrier 20 can be adjusted in height relative to the frame 10, which is not limited thereto. For example, the releasing operation member 34 releases the fixing of the engaging element 33 to the frame 10 and the carrier 20 during the inward movement to allow the engaging seat 32 to be adjusted between the first adjustment position X and the second adjustment position Y, so as to adjust the height of the carrier 20 on the frame 10, and the releasing operation member 34 engages the carrier 20 during the outward extending of the engaging seat 32 to prohibit the movement of the engaging seat 32 on the frame 10, so that the carrier 20 is kept at a certain position of the frame 10, but not limited thereto. In addition, the vehicle 20 is mainly classified into two types, one type is a vehicle 20 for seating an infant, such as an infant seat shown in fig. 6, but may also be an automobile safety seat used in an automobile, but is not limited thereto; another type is a carrier 20 that provides for an infant to lie, such as, but not limited to, an infant sleeping box. It is understood that the structure of carrier 20 is well known in the art and will not be described in detail herein. More specifically, the following:

as shown in fig. 4, 5, 11 to 14, the frame 10 is further provided with a second step portion 12 for the engaging component 33 to engage with to keep the engaging seat 32 at the first adjustment position X, when the carrier 20 is assembled to the frame 10 for backward use, the engaging component 33 performs a releasing movement under the linkage of the releasing operation component 34 to switch the engaging seat 32 between the first adjustment position X and the second adjustment position Y, i.e. the engaging component 33 can engage with the second step portion 12 when the engaging seat 32 reaches the first adjustment position X, the engaging component 33 can engage with the first step portion 11 when the engaging seat 32 reaches the second adjustment position Y, and the carrier 20 can be firmly and stably mounted with the frame 10 when the carrier 20 is backward used. Specifically, when the vehicle 20 is assembled to the frame 10 in a forward direction, the engaging element 33 engages with the second positioning portion 12 when the engaging seat 32 is located at the first adjustment position X, so that when the vehicle 20 used in a backward direction reaches the second adjustment position Y, the engaging element 33 engages with the second positioning portion 12 to prevent the vehicle 20 from sliding out of the frame 10, and the vehicle 20 is firmly and stably fixed to the frame 10.

As shown in fig. 4 to 14, the engaging assembly 33 includes an engaging member 331, a triggering member 332 and a connecting member 333, the releasing operation member 34 is linked with the engaging member 331, the engaging member 331 is telescopically disposed in the engaging seat 32, the engaging member 331 is selectively engaged with one of the first seat portion 11 and the second seat portion 12, the pushing structure 311 pushes the triggering member 332 to move when the vehicle 20 is assembled to the frame 10 in the forward direction, and the movable triggering member 332 is linked with the engaging member 331 to retract into the engaging seat 32, so that the structure of the engaging assembly 33 is simple and the arrangement and installation are convenient. Specifically, a first end of the connecting member 333 is connected to the card releasing operation member 34, and a second end of the connecting member 333 is connected to the engaging member 331, so that the card releasing operation member 34 and the engaging member 331 move synchronously, and the quick card releasing operation is facilitated. Preferably, the engaging member 331, the triggering member 332 and the connecting member 333 are integrally formed by, but not limited to, sheet metal or casting.

As shown in fig. 7 to 10, the trigger 332 is slidably and telescopically disposed on the engaging seat 32 to enable the trigger 332 to move together with the engaging member 331 more quickly, for example, a guide rail 321 is disposed in the engaging seat 32, and the trigger 332 is slidably mounted on the guide rail 321. Specifically, when the carrier 20 is assembled on the frame 10 in the forward direction, the pushing structure 311 pushes the trigger 332 to slide into the engaging seat 32, the trigger 332 pushes the connecting member 333 to move in the process of sliding into the engaging seat 32, and the moving connecting member 333 drives the engaging member 331 to retract into the engaging seat 32, so that the engaging member 33 smoothly and continuously moves during the card releasing movement, and the pushing of the trigger 332 against the connecting member 333 enables the engaging member 331 to smoothly retract into the engaging seat 32 to release the card. More specifically, the sliding direction of the trigger 332 intersects the moving direction of the connecting member 333, so that no moving interference occurs between the trigger 332 and the connecting member 333, and the engaging member 331 can be effectively and smoothly driven to move. In order to enable the releasing operation member 34 and the triggering member 332 retracted into the engaging seat 32 to automatically withdraw and reset, the engaging assembly 33 further includes a releasing reset member 334 disposed between the releasing operation member 34 and the engaging seat 32 and a triggering reset member 335 disposed between the triggering member 332 and the engaging seat 32, the releasing reset member 334 has a tendency to drive the releasing operation member 34 to extend out of the engaging seat 32, and the triggering reset member 335 has a tendency to drive the triggering member 332 to extend out of the engaging seat 32. For example, the releasing and resetting element 334 and/or the triggering and resetting element 335 are elastic elements, such as but not limited to compression springs or extension springs, but according to actual needs, the releasing and resetting element 334 and the triggering and resetting element 335 may also be magnetic elements, and the purpose of automatically resetting the triggering element 332 and the releasing and resetting operation element 34 is achieved by repulsion between opposite polarities by mounting one magnetic element on the engaging seat 32 and the other magnetic element on the releasing and resetting operation element 34 and/or the triggering element 332, which is not limited thereto.

As shown in fig. 4, 5 and 9 to 14, the slide rail 13 is mounted on the frame 10, the engaging seat 32 is slidably mounted on the slide rail 13, and the first step portion 11 and the second step portion 12 are disposed on the slide rail 13, so as to facilitate the position adjustment of the engaging seat 32 on the frame 10. For example, the sliding rail 13 is convexly installed on the upper handle bar of the frame 10 to facilitate the installation of the sliding rail 13, but not limited thereto. Specifically, the slide rail 13 is further provided with a plurality of fine adjustment positioning portions 14 spaced apart from each other, the fine adjustment positioning portions 14 are located between the first positioning portion 11 and the second positioning portion 12, and when the carrier 20 is assembled to the frame 10, the engaging component 33 can selectively engage with one of the fine adjustment positioning portions 14 in addition to the first positioning portion 11 and the second positioning portion 12, so as to adjust the position of the carrier 20 on the frame 10 more flexibly. For example, 3 fine-adjustment positioning portions 14 are disposed between the first positioning portion 11 and the second positioning portion 12, so that the engaging seat 32 can perform 5-level position adjustment on the frame 10, and the carrier 20 can be used more flexibly. More specifically, the engaging component 33 is also released from the fine adjustment positioning portion 14 adjacent to the first positioning portion 11 when the carrier 20 is assembled on the frame 10 in the forward use state, so as to further limit the height of the carrier 20 when assembled on the frame 10 in the forward use state, thereby ensuring the safety of the stroller 100 in use. For example, the first positioning portion 11, the second positioning portion 12 and the fine adjustment positioning portion 14 are each a slot structure, so that the engaging member 331 can be selectively inserted into the first positioning portion 11, the second positioning portion 12 or a fine adjustment positioning portion 14, and the engaging seat 32 can be conveniently kept at a certain position of the frame 10.

As shown in fig. 7 to 14, the lower sidewall of the first positioning section 11 and the lower sidewall of the fine adjustment positioning section 14 adjacent to the first positioning section 11 respectively have a forward sliding-out slope 15 that is obliquely arranged from top to bottom to outside, the carrier 20 is assembled to the frame 10 in a forward use manner, and when the engaging member 331 extends to the first positioning section 11 or the fine adjustment positioning section 14 adjacent to the first positioning section 11, the pushing structure 311 pushes the trigger member 332, the movable trigger member 332 drives the engaging member 331 to retract into the engaging seat 32, and at this time, the engaging member 333 slides outwards and finally abuts against the forward sliding-out slope 15, so that the engaging member 331 automatically slides downwards and is only engaged with a remaining fine adjustment positioning section 14 or a remaining second positioning section 12, and the purpose of automatically limiting the height of the carrier 20 from the frame 10 according to the installation manner of the carrier 20 is achieved. In order to ensure that the engaging member 331 can be selectively engaged with one of the first positioning section 11, the second positioning section 12 or any one of the fine adjustment positioning sections 14 when the vehicle 20 is assembled to the frame 10 in the backward direction, the forward sliding-out inclined plane 15 does not extend to the bottom of the slot hole where the forward sliding-out inclined plane 15 is located, so that a supporting sidewall 16 is further provided between the forward sliding-out inclined plane 15 and the bottom of the slot hole where the forward sliding-out inclined plane 15 is located, when the vehicle 20 is assembled to the frame 10 in the backward direction, the engaging member 331 located in the first positioning section 11 or the fine adjustment positioning section 14 adjacent to the first positioning section 11 is supported by the supporting sidewall 16, so that the engaging member 331 can be stably engaged with any one of the slot holes, and when the vehicle 20 is assembled to the frame 10 in the backward direction, the engaging seat 32 can achieve the purpose of 5-level position adjustment relative to. Specifically, the upper side wall of at least one of the first positioning section 11, the second positioning section 12 and the fine adjustment positioning section 14 has a backward sliding inclined plane 17 that is inclined inward from top to bottom, and the engaging member 331 has a matching sliding inclined plane 3311 that matches with the backward sliding inclined plane 17, so when the carrier 20 is assembled backward to the frame 10, if the engaging member 331 is adjusted from a slot of a low gear to a slot of a high gear, the engaging member 331 can conveniently separate from the slot of the low gear because the sliding inclined plane 17 matches with the matching sliding inclined plane 3311 to slide, the whole operation process does not need to press the releasing operating member 34, and the carrier 20 can be directly moved upward to realize adjustment, and the operation is simple and fast.

As shown in fig. 7 to 10, the connecting seat 31 has a card insertion cavity 312, the pushing structure 311 is located in the card insertion cavity 312, and the engaging seat 32 is partially inserted into the card insertion cavity 312, preferably, the pushing structure 311 and the triggering member 332 are disposed opposite to each other, so that the triggering member 332 can be pushed to extend into the engaging seat 32 quickly and continuously when the connecting seat 31 and the engaging seat 32 are engaged, it can be understood that the structure of the connecting seat 31 and the engaging seat 32 is well known in the art, and therefore, detailed description thereof is omitted. For example, the pushing structure 311 is a rib plate located in the card insertion cavity 312, so the pushing structure 311 has a simple structure and is easy to install and arrange. Of course, according to actual needs, the pushing structure 311 can also be a protrusion or a stopper located in the card insertion cavity 312, which can achieve the effect of quickly pushing the trigger 332, so the invention is not limited thereto.

Referring to fig. 1 to 14, when the vehicle 20 is assembled to the frame 10 in a backward use mode, the engaging seat 32 is partially inserted into the card-inserting cavity 312 of the connecting seat 31, the pushing structure 311 in the card-inserting cavity 312 is staggered from the trigger 332, and the engaging member 331 can selectively engage with the first positioning section 11, the second positioning section 12, or a fine-tuning positioning section 14.

The control card operating part 34 is operated to move inwards towards the engaging seat 32, the release card operating part 34 doing the inwards-contracting movement links the connecting part 333 to move, the moving connecting part 333 drives the engaging part 331 to move inwards towards the engaging seat 32, so that the engaging part 331 is released from the slot hole where the engaging part is located, at this time, the carrier 20 can be operated to move up and down relative to the frame 10 to adjust the assembling position of the carrier on the frame 10, the engaging seat 32 can do 5-level position adjustment relative to the frame 10 at this time, namely, the engaging part 331 can be selectively engaged with any one of the 5 slot holes. Then, the releasing operation member 34 is released, and under the action of the releasing reset member 334, the engaging member 331 and the releasing reset member 334 extend out of the engaging seat 32 again, and the engaging member 331 is inserted into the aligned slot hole to engage with the slot hole, thereby completing the height adjustment of the carrier 20. Of course, the position of vehicle 20 on frame 10 can also be adjusted by directly carrying vehicle 20 upward.

When the carrier 20 is assembled on the frame 10 in a forward use manner, part of the engaging seat 32 is inserted into the card-inserting cavity 312 of the connecting seat 31, at this time, the pushing structure 311 in the card-inserting cavity 312 is disposed opposite to the trigger 332, the pushing structure 311 pushes the trigger 332 to slide into the engaging seat 32, the trigger 332 pushes the connecting member 333 to move in the process of sliding into the engaging seat 32, the moving connecting member 333 drives the engaging member 331 to retract into the engaging seat 32, so that when the engaging member 331 extends into the first positioning portion 11 or the fine-adjustment positioning portion 14 adjacent to the first positioning portion 11, the engaging member 331 extends outward and abuts against the forward sliding-out inclined surface 15, therefore, the engaging member 331 automatically slides away from the first positioning portion 11 or the fine adjustment positioning portion 14 adjacent to the first positioning portion 11, and can only engage with the remaining fine adjustment positioning portion 14 or the second positioning portion 12, so as to realize the purpose of automatically limiting the height of the vehicle 20 and the frame 10 according to the mounting mode of the vehicle 20.
