[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] A specific embodiment of this utility model provides a child seat folding mechanism for electric bicycles, as shown in the attached figure. Figure 1 - Appendix Figure 9As shown, it mainly includes a connecting seat 1, a support rod 2, a sleeve 3, and a limiting frame 4. One end of the support rod 2 is connected to the connecting seat 1, and the other end is provided with a limiting groove 5. The connecting seat 1 is used to connect with the electric bicycle. Specifically, the connecting seat 1 is located at the foot pedal position of the electric bicycle, that is, the platform between the two pedals. The opening direction of the limiting groove 5 is opposite to that of the connecting seat 1, that is, the opening direction of the limiting groove 5 is upward. The sleeve 3 is slidably sleeved on the support rod 2 and can slide up and down along the support rod 2. One end of the limiting frame 4 is rotatably connected to the sleeve 3. The limiting post 6 of the limiting frame 4 is located inside the sleeve 3 and can extend into the limiting groove 5. The limiting frame 4 is used to achieve the limiting connection with the support rod 2 and to connect the seat part.

[0029] The folding mechanism for electric bicycle child seats includes a folded state and an unfolded state;

[0030] In the folded state, the limiting post 6 is located outside the limiting groove 5 and the limiting frame 4 can rotate relative to the support rod 2. The limiting frame 4 is folded to a position close to the support rod 2, thus realizing the folding of the seat.

[0031] When unfolded, the limiting post 6 is located within the limiting groove 5 and restricts the relative rotation of the limiting frame 4 and the support rod 2. The limiting effect between the limiting post 6 and the limiting groove 5 restricts the relative rotation of the limiting frame 4 and the support rod 2, thus ensuring that the seat is stable and does not wobble when unfolded, providing a stable support for the child.

[0032] This application uses this folding structure to realize the folding function of the child seat. When not carrying a child, it can be folded to reduce the space occupied by the child seat, thereby ensuring the user's riding experience. When it is necessary to carry a child, it can be unfolded to achieve the purpose of carrying the child.

[0033] In a specific embodiment of this application, a locking button 7 and a locking spring 8 are also included, in conjunction with the attached... Figure 3 and attached Figure 7 As shown, the locking button 7 and the universal locking spring 8 are slidably mounted on the support rod 2. The sleeve 3 has a locking hole 9 on its wall. The locking button 7 can extend into the locking hole 9. In this way, the locking button 7 is located in the locking hole 9 and plays a locking role. At this time, the sleeve 3 cannot slide relative to the support rod 2. When the locking button 7 is pressed, it can be unlocked and the sleeve 3 can slide relative to the support rod 2.

[0034] Specific appendix Figure 1 , 3 As shown in Figures 6 and 7, there are two locking holes 9, corresponding to the folded state and the unfolded state, respectively.

[0035] In a specific embodiment of this application, there are two support rods 2 and two sleeves 3. The two support rods 2 are symmetrically arranged on the connecting seat 1. This arrangement of two support rods 2 can provide a more stable connection and support. Thus, the limiting frame 4 can be "T" shaped. The two opposite ends of the limiting frame 4 are rotatably connected to the two sleeves 3 respectively. The connection is achieved from both sides of one end of the limiting frame 4, ensuring sufficient support strength so that it can be stable and not shake when carrying a child, ensuring that it has sufficient stability.

[0036] In specific embodiments of this application, as shown in the appendix Figure 2 As shown, the connecting seat 1 is provided with a binding groove 10, which is used to accommodate binding ropes. The binding ropes are used to connect the connecting seat 1 to the foot pedal of the electric bicycle. In practice, at least two binding ropes may be used for connection. Therefore, at least two binding grooves 10 can be provided on the connecting seat 1 to ensure a better connection effect, so that the electric bicycle child seat has sufficient stability after being installed on the electric bicycle and is not easy to shake.

[0037] Specifically, this application also includes a seat cover 11, which is detachably connected to the connecting seat 1. The seat cover 11 can cover the binding groove 10, so that the binding groove 10, i.e. the binding rope, is not visible from the outside, which makes it more aesthetically pleasing.

[0038] As attached Figure 9 As shown, a snap-fit ​​protrusion 14 can be provided at the bottom position of the seat cover 11 facing the connecting seat 1, and a corresponding snap-fit ​​groove 15 can be provided on the connecting seat 1. The seat cover 11 and the connecting seat 1 are detachably connected through the snap-fit ​​of the snap-fit ​​protrusion 14 and the snap-fit ​​groove 15. The number of snap-fit ​​protrusions 14 and snap-fit ​​grooves 15 are multiple and they are set one-to-one to ensure a good snap-fit ​​effect.

[0039] In a specific embodiment of this application, the limiting post 6 is a square post and the limiting groove 5 is a U-shaped groove. This structure can ensure that the limiting post 6 will not rotate at a large angle after it extends into the limiting groove 5, thereby ensuring the stability of the seat.

[0040] In specific embodiments of this application, in conjunction with the appendix Figure 8 As shown, the limiting frame 4 includes a connecting body 12, a limiting post 6, and a connecting rod 13. The connecting body 12 can be a cylindrical structure. Limiting posts 6 are provided at both ends of the connecting body 12. The limiting posts 6 are located inside the sleeve 3. At the end of the limiting post 6 away from the connecting body 12, there is an arc-shaped end cap. This arc-shaped end cap is located outside the sleeve 3 and can close the port of the sleeve 3. The connecting rod 13 is provided on the connecting body 12. The rotation of the connecting body 12 can drive the connecting rod 13 to swing. The connecting rod 13 is used to connect the seat part.
