[0025] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 and Figure 2 As shown, this application provides a foldable baby seat, including a push handle 10, a bottom bracket 20, a backrest bracket 30, a seat bracket 40, an armrest assembly 50, and a canopy rod 60. The backrest bracket 30 is fixed to the seat bracket 40. The seat bracket 40 is mounted to the bottom bracket 20.

[0028] The push handle 10 includes an upper push handle 11 and a lower push handle 12. The two ends of the lower push handle 12 are rotatably connected to the bottom bracket 20 and the upper push handle 11, respectively. A first locking mechanism (not shown) is connected between the upper push handle 11 and the lower push handle 12, and a second locking mechanism (not shown) is connected between the lower push handle 12 and the bottom bracket 20.

[0029] The elastic member (not shown) is connected between the upper push handle 11 and the lower push handle 12, so that the elastic member can drive the upper push handle 11 to rotate relative to the lower push handle 12 when the first locking mechanism is in the unlocked state. The elastic member can be a torsion spring.

[0030] The bottom support 20 includes a front support 21 and a rear support 22 rotatably connected. The lower push handle 12 is rotatably connected to the rear support 22, and the second locking mechanism is connected between the lower push handle 12 and the rear support 22. The armrest assembly 50 includes an armrest 51 and an assembly rod 52. The armrest 51 is connected to the lower push handle 12. The assembly rod 52 connects the armrest 51 and the rear support 22, so that the lower push handle 12 can drive the rear support 22 to move relative to the front support 21 during rotation.

[0031] The back support 30 includes a backrest 31 fixed to the seat support 40, a mounting rod 32 fixed to the backrest 31, and a linkage rod 300. The two ends of the linkage rod 300 are rotatably connected to the backrest 31 and the rear support 22, respectively, so that the rear support 22 can drive the backrest 31 and the mounting rod 32 to rotate.

[0032] In some embodiments, the linkage rod 300 can be directly rotatably connected to the rear support 22, which is simple in structure and easy to manufacture. In other embodiments, the linkage rod 300 can be indirectly rotatably connected to the rear support 22, as long as the two can rotate relative to each other.

[0033] The upper push handle 11 is U-shaped, and the lower push handle 12 is provided in a pair, each being assembled to one end of the upper push handle 11. The upper push handle 11 and the lower push handle 12 are hollow. The torsion spring and the first locking mechanism are installed in the mounting box 13 connected between the upper push handle 11 and the lower push handle 12. One end of the lower push handle 12 is provided with a hollow support connecting portion 121, and the second locking mechanism is installed in the support connecting portion 121.

[0034] The upper push handle 11 is provided with an unlocking switch 111. The unlocking switch 111 and the first locking mechanism are connected by a pull cable structure. When the user presses the unlocking switch 111, the pull cable structure drives the first locking mechanism to be unlocked, and the elastic force of the torsion spring is released, driving the upper push handle 11 to rotate. After the upper push handle 11 rotates by a certain angle, the pull cable connected to the upper push handle 11 pulls the second locking mechanism to be unlocked, and the lower push handle 12 is rotated by gravity, so that the foldable baby seat is automatically folded.

[0035] Since the torsion spring can drive the upper push handle 11 to rotate relative to the lower push handle 12, and the upper push handle 11 can unlock the second locking mechanism during rotation, the bottom support 20 and the back support 30 can be folded by the linkage rod during the folding of the push handle 10, without relying entirely on manual operation of the user, thereby improving the folding efficiency of the foldable baby seat. At the same time, since the first locking mechanism and the second locking mechanism are provided, the push handle 10 can be supported by using multiple locking mechanisms, thereby improving the strength of the foldable baby seat, eliminating the need for additional reinforcing rods, reducing the cost of the foldable baby seat, and improving the aesthetic appearance of the foldable baby seat.

By providing the support frame 42 to connect the seat mounting frame 41 and the bottom support 20, the structural strength of the seat mounting frame 41 is improved. In other embodiments, the specific structural form of the seat support 40 is not limited.

[0043] Specifically, as shown in Figure 4 , the seat mounting frame 41 includes a pair of first rod members 411 and a pair of second rod members 412. The first rod member 411 is in the shape of a long tube. The second rod member 412 is in the shape of a long plate. The pair of first rod members 411 are symmetrically arranged on the left and right sides of the foldable baby seat, and the second rod member 412 connects the pair of first rod members 411 and is arranged in intervals along the front-to-back direction of the foldable baby seat to improve the structural strength of the seat mounting frame 41.

[0044] In the embodiment in which the bottom support 20 comprises the front support 21 and the rear support 22, the support frame 42 is rotatably connected with the front support 21 and the assembly rod 52, respectively. In the folding process, the support frame 42 can be folded together with the front support 21 and the rear support 22, thereby improving the folding efficiency of the foldable baby seat.

[0045] In an embodiment, as shown in Figure 3 and Figure 4 the support frame 42 can comprise a first support frame 421 and a second support frame 422 rotatably connected with each other. The first support frame 421 is connected with the seat mounting frame 41, and the second support frame 422 is mounted to the bottom support 20. By setting the first support frame 421 and the second support frame 422 to be rotatably connected with each other, the support frame 42 can be folded, so that the volume of the foldable baby seat after folding is reduced. In other embodiments, the specific structure of the support frame 42 is not limited.

[0046] In an embodiment, the support frame 42 can further comprise a connecting block 423, the first support frame 421 is fixedly connected with the connecting block 423, and the second support frame 422 is rotatably mounted with the connecting block 423. By setting the connecting block 423 to rotatably mount the first support frame 421 and the second support frame 422, the structural strength of the foldable baby seat is improved. In other embodiments, the manner in which the first support frame 421 and the second support frame 422 are rotatably connected is not limited.

[0047] Specifically, the first support frame 421 is in the shape of a tubular U and is rotatably connected with the first rod member 411. The upper half of the connecting block 423 is fixedly connected with the first support frame 421 by riveting or the like. The lower half of the connecting block 423 is provided with a hole structure, and the second support frame 422 extends into the hole structure to achieve rotatable connection.

[0048] The second support frame 422 comprises a vertical portion 4221 and a horizontal portion 4222. The vertical portion 4221 is in the shape of an inverted U. The vertical portion 4221 is rotatably connected with the connecting block 423. The horizontal portion 4222 is also in the shape of a U and is rotatably connected with the assembly rod 52. The horizontal portion 4222 extends from both ends of the vertical portion 4221.

[0049] The front end of the seat mounting frame 41 is provided with a pair of extension rods 43. When the length of the seat mounting frame 41 is not enough, the extension rods 43 can be rotated to be flush with the seat mounting frame 41, thereby extending the overall length of the seat support 40, and the baby can put his feet on the extension rods 43. When the length of the seat mounting frame 41 is enough, the extension rods 43 can be lowered to maintain the appearance of the foldable baby seat.

[0050] In one embodiment, the rear support 22 further includes a slider (not shown), and the rear support 22 is provided with a groove 227. The slider is slidably mounted with the groove 227. By providing the groove 227 and the slider, the smoothness of the movement of the rear support 22 is improved, and the folding efficiency of the foldable baby seat is improved.

[0051] In an embodiment where the linkage rod 300 is indirectly connected to the rear support 22, the linkage rod 300 can be rotatably connected to the assembly rod 52. Since the assembly rod 52 is slidably connected to the rear support 22, by rotatably connecting the linkage rod 300 to the assembly rod 52, there is relative rotational movement between the linkage rod 300, the rear support 22, and the assembly rod 52. The movements of the rear support 22 and the assembly rod 52 can be superimposed at the linkage rod 300, improving the folding efficiency of the foldable baby seat.

[0052] like Figures 2 to 7 As shown below, the specific folding process of the foldable baby seat is described.

[0053] First, the user presses the unlock switch 111. The cable structure connected to the unlock switch unlocks the first locking mechanism, releasing the elastic force of the elastic element and driving the upper push handle 11 to rotate relative to the lower push handle 12. After the upper push handle 11 rotates to a certain angle, the cable connected to the upper push handle 11 unlocks the second locking mechanism, causing the lower push handle 12 to rotate relative to the support rod 221 under the action of gravity.

[0054] The above describes the process of folding down the handle 10 of the foldable baby seat. Figure 6 In the view shown, the upper push handle 11 rotates counterclockwise relative to the lower push handle 12, and the lower push handle 12 rotates clockwise relative to the support rod 221. The mounting rod 32 rotates clockwise relative to the lower push handle 12.

[0055] During the rotation of the push handle 12, the assembly rod 52 moves, causing the slider and the slide groove 227 to move relative to each other. Since the slider is located on the rear support 22, the relative movement of the slider and the slide groove 227 can drive the rear support 22 and the front support 21 to move relative to each other, thus folding them together. Since the second support frame 422 is rotatably connected to the assembly rod 52, during the movement of the rear support 22, the second support frame 422 rotates relative to the first support frame 421, causing the support frame 42 to fold. At the same time, since the linkage rod 300 is rotatably connected to the rear support 22, during the rotation of the rear support 22, the linkage rod 300 moves, causing the backrest 31 to rotate, thereby causing the mounting rod 32 fixed to the backrest 31 to fold together.

[0056] The above describes the process of folding up the remaining parts of the foldable baby seat. Figure 6 and Figure 7From the perspective of the front support 21, the support rod 221 rotates counterclockwise. The first support frame 421 rotates counterclockwise relative to the seat mounting frame 41. The second support frame 422 rotates clockwise relative to the first support frame 421.

[0057] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structure described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
