Description

[Technical Field]

[0001] This invention relates to the field of baby product technology, and more particularly to a foldable child carrier. [Previous Technology]

[0002] Strollers are almost essential items for babies. Strollers generally consist of a frame and a seat on the frame. In the current technology, the baby seat is basically fixedly connected to the frame and cannot be disassembled, which is inconvenient for cleaning and reusing the seat. Although there are some baby seat parts that can be detached from the frame, they need to be disassembled and folded separately when carried out, which brings certain inconvenience to travel. [Summary of the Invention]

[0003] The object of the present invention is to provide a foldable child vehicle in which the folded seat section can be rotated relative to the frame.

[0004] To achieve the above objective, the present invention provides a foldable child vehicle, including a seat portion pivotally connected to a frame and a backrest portion folded down relative to the seat portion. A locking mechanism is provided between the seat portion and the frame to lock the relative position between the seat portion and the frame. A movable drive member is provided between the seat portion and the backrest portion. When the backrest portion is in the unfolded position, the drive member cannot release the locking mechanism. When the backrest portion is in the folded position, the movement of the drive member causes the locking mechanism to release the seat portion from the frame, so that the seat portion can rotate relative to the frame.

[0005] Compared with the prior art, the foldable child vehicle of the present invention includes a frame, a seat, and a backrest folded onto the seat. The seat is pivotally connected to the frame, and the backrest can be folded relative to the seat. A locking mechanism is provided between the seat and the frame, and a drive member for driving the locking mechanism is provided between the backrest and the seat. When the backrest is in the unfolded position, the drive member cannot release the locking mechanism. When the backrest is in the folded position, the movement of the drive member can release the locking mechanism from the seat, allowing the seat to rotate relative to the frame. In the foldable child vehicle of the present invention, the drive member for driving the locking mechanism can only act on the locking mechanism when the backrest is folded, effectively preventing misuse of the child vehicle during use and making it safer and more reliable. The foldable child carrier of the present invention, after the backrest is folded relative to the seat, releases the locking mechanism via the movement of the drive component, allowing the seat to rotate relative to the frame and adjust its relative position. This results in a smaller overall size, making it easier to carry and store. The foldable child carrier of the present invention features a novel structure, convenient operation, safety, reliability, and ease of carrying and storage.

Implementation Method

[0042] In order to explain the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0043] Referring to Figures 1 to 5, the present invention provides a foldable child vehicle 100, including a seat portion 50 pivotally connected to a frame and a backrest portion 40 folded down relative to the seat portion 50. A locking mechanism 10 is provided between the seat portion 50 and the frame to lock the relative position between them. The seat portion 50 is pivotally connected to the frame via a second fixing seat 51 and locked by the locking mechanism 10, thus fixing the seat portion 50 to the frame. When the locking mechanism 10 is released, the seat portion 50 can rotate along the pivot point between the seat portion 50 and the frame. Specifically, a movable drive member 20 is also provided between the seat portion 50 and the backrest portion 40. During the folding process, the first fixing seat 41 rotates relative to the second fixing seat 51, and at this time, the drive member 20 rotates with the rotation of the first fixing seat 41, that is, the drive member 20 rotates relative to the second fixing seat 51. Understandably, when the backrest 40 is unfolded relative to the seat 50, or during the folding process of the backrest 40, the drive member 20 cannot release the locking mechanism 10. When the backrest 40 is folded into the seat 50, the drive member 20 can act on the locking mechanism 10. The movement of the drive member 20 causes the locking mechanism 10 to release the seat 50 from the frame, allowing the seat 50 to rotate relative to the frame. The foldable child carrier 100 of the present invention is easy to operate and safer to use.

[0044] By adopting the above technical solution, the foldable child vehicle 100 of the present invention includes a frame, a seat 50, and a backrest 40 folded onto the seat 50. The seat 50 is pivotally connected to the frame, and the backrest 40 can be folded relative to the seat 50. A locking mechanism 10 is provided between the seat 50 and the frame, and a driving member 20 for driving the locking mechanism 10 is provided between the backrest 40 and the seat 50. When the backrest 40 is unfolded relative to the seat 50, the driving member 20 cannot release the locking mechanism 10, and the seat 50 cannot rotate relative to the frame. When the backrest 40 is folded relative to the seat 50, the driving member 20 can act on the locking mechanism 10, and the movement of the driving member 20 can release the locking mechanism 10, thereby allowing the seat 50 to rotate relative to the frame. The foldable child carrier 100 of the present invention allows the driving member 20 to release the locking mechanism 10 only when the backrest 40 is folded, effectively preventing misuse of the child carrier during use and making it safer and more reliable. When the backrest 40 is folded relative to the seat 50, the movement of the driving member 20 releases the locking mechanism 10, allowing the seat 50 to rotate relative to the frame and adjust its relative position. This results in a smaller overall size, making it easier to carry and store. The foldable child carrier 100 of the present invention features a novel structure, convenient operation, safety, reliability, and ease of carrying and storage.

[0045] Please refer to Figures 6 to 13. In some optional embodiments, a first fixed seat 41 is connected to the backrest 40, and a second fixed seat 51 is connected to the seat 50. When the backrest 40 is folded, the first fixed seat 41 rotates relative to the second fixed seat 51. A drive member 20 is mounted on the first fixed seat 41. When the backrest 40 is folded relative to the seat 50, the drive member 20 can rotate with the rotation of the first fixed seat 41, meaning that the drive member 20 remains stationary relative to the first fixed seat 41 during the folding process. Specifically, the drive member 20 is also connected to an operating member 30 for driving the drive member 20. The operating member 30 is connected to the connecting portion 22 of the drive member 20 and is located outside the first fixed seat 41 to facilitate user operation. The operating member 30 has a flexible structure, which makes operation more comfortable and convenient, and the flexible structure of the operating member 30 does not affect the use of the child carrier when not in operation. In this embodiment, when the backrest 40 is folded into the seat 50, the drive member 20 rotates with the first fixed base 41 to a position where it can act on the locking mechanism 10. At this time, pulling the operating member 30 located outside the first fixed base 41 causes the drive member 20 to rotate relative to the first fixed base 41, thereby enabling the drive member 20 to release the locking mechanism 10.

[0046] Referring to Figures 6 to 13, in some optional embodiments, the foldable child vehicle 100 further includes a positioning member 12 that can be detachably engaged with the frame. The positioning member 12 engages with both the second mounting base 51 and the frame, allowing the seat portion 50 and the backrest portion 40 on the seat portion 50 to be detachably mounted on the frame. The locking mechanism 10 includes a locking member 11 movably disposed on the second mounting base 51. The locking member 11 engages with the positioning member 12 to lock the relative position between the seat portion 50 and the positioning member 12. When the movement of the drive member 20 acts on the locking member 11, the movement of the drive member 20 causes the locking member 11 to disengage from the positioning member 12 to release the lock, thereby allowing the seat portion 50 to rotate relative to the frame or the positioning member 12.

[0047] Please refer to Figures 6, 7, and 13. In this embodiment, the locking member 11 has a locking part 111 extending out of the second fixed seat 51 at the end away from the transmission member 13, and the positioning member 12 has a positioning part 121 that cooperates with the locking part 111. When the locking part 111 protrudes out of the second fixed seat 51 and cooperates with the positioning part 121, the seat part 50 is locked to the frame. When the driving member 20 contacts and moves with the transmission member 13, the transmission member 13 can drive the locking part 111 to retract into the second fixed seat 51, thereby disengaging the locking part 111 from the positioning part 121 to release the lock, and thus allowing the seat part 50 to rotate relative to the frame or the positioning member 12.

[0048] Please refer to Figures 6 to 13. In some optional embodiments, a transmission member 13 is also provided between the driving member 20 and the locking member 11, and the driving member 20 acts on the locking member 11 through the transmission member 13. The driving member 20 is rotatably mounted on the first fixed base 41, and the locking member 11 is telescopically mounted on the second fixed base 51. An arc-shaped groove 411 for the locking member 11 to pass through is provided on the first fixed base 41. When the first fixed base 41 rotates relative to the second fixed base 51, the locking member 11 is located at different positions in the arc-shaped groove 411. It can be understood that during the folding process of the backrest 40, the driving member 20 rotates with the first fixed base 41, while the locking member 11 remains stationary with the second fixed base 51. At this time, the driving member 20 rotates relative to the locking member 11. By providing the through arc-shaped groove 411, interference of the locking member 11 with the rotation of the first fixed base 41 and the driving member 20 can be avoided. Specifically, the transmission member 13 is connected to the locking member 11 and is provided on the movement path of the driving member 20. When the driving member 20 rotates to contact the transmission member 13, the operation of the operating member 30 causes the driving member 20 to rotate relative to the first fixed base 41 and act on the transmission member 13, so that the transmission member 13 drives the locking member 11 to move. The transmission member 13 is movably disposed between the first fixed base 41 and the driving member 20. The transmission member 13 can move along the thickness direction of the first fixed base 41 and the driving member 20, thereby driving the locking member 11 to extend and retract.

[0049] Please refer to Figures 8 to 14. In some optional embodiments, the driving member 20 is provided with a driving part that cooperates with the transmission member 13. The transmission member 13 is disposed on the movement path of the driving part. Specifically, the driving part is a driving ramp 21. The driving member 20 moves to make the driving ramp 21 push the transmission member 13, thereby causing the transmission member 13 to drive the locking member 11 to move to disengage from the locked position. Among them, a straight part 211 is provided at one end of the driving ramp 21 for the transmission member to stop. When the transmission member 13 is pushed to the straight part 211 by the driving ramp 21, the displacement of the locking member 11 is sufficient to disengage from the locked position to release the lock. Since the driving ramp 21 is inclined, the transmission member 13 will have a downward tendency on the driving ramp 21. The straight part 211 is provided at the highest point of the driving ramp 21, so that the transmission member 13 can be positioned more stably on the driving ramp 21, thereby better driving the locking member 11 to disengage from the positioning member 12.

[0050] Referring to Figures 8 to 12, in some optional embodiments, a first limiting member 412 for restricting the rotation of the driving member 20 in a first direction is provided on the first fixed base 41, and a first limiting part 23 cooperating with the first limiting member 412 is provided on the driving member 20. A second limiting member 413 for restricting the rotation of the driving member 20 in a second direction is also provided on the first fixed base 41, and a second limiting part 24 cooperating with the second limiting member 413 is provided on the driving member 20. The first direction is the direction in which the driving member 20 rotates counterclockwise relative to the first fixed base 41. The second direction is the direction in which the driving member 20 rotates clockwise relative to the first fixed base 41. It can be understood that the operating member 30 pulls the driving member 20 to rotate between the first limiting member 412 and the second limiting member 413. When the first limiting part 23 abuts against the first limiting member 412, the locking mechanism 10 is in a locked state. When the second limiting part 24 abuts against the second limiting member 413, the locking mechanism 10 is in the unlocked state.

[0051] Please refer to Figures 8 to 13. One end of the locking member 11 is telescopically mounted on the second fixed base 51, and the other end of the locking member 11 protrudes out of the arc-shaped groove 411 and is provided with a mounting part 112 that cooperates with the transmission member 13. Specifically, the mounting part 112 is a through mounting hole, and the transmission member 13 passes through the mounting hole. The mounting part 112 can also be a locking part that engages and fixes with the transmission member 13, as long as the locking member 11 and the transmission member 13 can be connected together and the transmission member 13 drives the locking member 11 to move. The present invention does not impose any specific limitations on this. On the other hand, a second reset member 15 is provided on the locking member 11 to make the locking member 11 always have a tendency to reset. When the driving member 20 rotates and resets, in order to prevent the transmission member 13 from being stuck between the fixed base 41 and the driving inclined surface 21, a second reset member 15 is provided on the locking member 11 to drive the locking member 11 to reset, so that the locking member 11 always has a tendency to lock with the positioning member 12. Specifically, the second reset member 15 is a spring structure, or it may be other elastic structures that can be compressed and released.

[0052] Please refer to Figures 8 to 14. In some optional embodiments, a first reset member 14 is provided on the first fixed base 41 to ensure that the driving member 20 always has a reset tendency. Specifically, the first reset member 14 is a tension spring. When the driving member 20 rotates along the first fixed base 41, it will cause the tension spring to deform under force. When the force acting on the driving member 20 is removed, the tension spring will cause the driving member 20 to reset. In this embodiment, the outer periphery of the driving member 20 is a circular structure so that it can rotate and cooperate with the first fixed base 41. The driving member 20 is connected to the first fixed base 41 on the backrest 40. When the backrest 40 is unfolded relative to the seat 50, or when the backrest 40 is folded relative to the seat 50, the driving ramp 21 on the driving member 20 is in a position away from the transmission member 13. At this time, operating the operating member 30 will not make the driving ramp 21 act on the transmission member 13. When the backrest 40 is folded relative to the seat 50, the drive member 20 rotates with the first fixed base 41 to a position where the drive ramp 21 can drive the transmission member 13. At this time, operating the operating member 30 allows the drive member 20 to rotate relative to the first fixed base 41. The rotation of the drive member 20 causes the drive ramp 21 to act on the transmission member 13, thereby disengaging the locking member 11 from the positioning member 12. This allows the seat 50 with the backrest 40 folded to rotate relative to the frame, and the positions of the seat 50 and the backrest 40 relative to the frame can be adjusted, making the overall size of the child vehicle smaller after folding, and easier to carry and store.

[0053] As shown in Figures 1 to 14, the foldable child vehicle 100 of the present invention includes a frame, a seat 50, and a backrest 40 folded onto the seat 50. The seat 50 is pivotally connected to the frame, and the backrest 40 can be folded relative to the seat 50. A locking mechanism 10 is provided between the seat 50 and the frame, which locks the seat 50 to the frame. When the locking mechanism 10 is released, the seat 50 can rotate relative to the frame. A drive member 20 for driving the locking mechanism 10 is connected between the backrest 40 and the seat 50. When the backrest 40 is unfolded relative to the seat 50, or during the folding process, the drive member 20 cannot release the locking mechanism 10, the locking mechanism 10 is locked, and the seat 50 cannot rotate relative to the frame. When the backrest 40 is folded relative to the seat 50, the drive member 20 rotates with the first fixed seat 41 to approach the transmission member 13. At this time, the movement of the drive member 20 can release the locking mechanism 10, thereby allowing the seat 50 to rotate relative to the frame. In the foldable child carrier 100 of the present invention, the drive member 20, which drives the locking mechanism 10, can only act on the locking mechanism 10 when the backrest 40 is folded, effectively preventing misuse of the child carrier during use and making it safer and more reliable. After the backrest 40 is folded relative to the seat 50, the movement of the drive member 20 releases the locking mechanism 10, allowing the seat 50 to unlock from the frame, thus enabling the seat 50 to rotate relative to the frame to adjust the relative position between the seat 50 and the frame, resulting in a smaller overall size and easier carrying and storage. The foldable child carrier 100 of the present invention has a novel structure, is easy to operate, safe and reliable, and is easy to carry and store.

Therefore, any equivalent variations made in accordance with the scope of the patent application of the present invention shall fall within the scope of the present invention.
