[0025] Example

[0026] like Figure 1 and Figure 2 As shown, this utility model proposes a shock-absorbing support assembly for a folding electric bicycle, including a top cover 1 and a limiting mechanism at the bottom of the top cover 1. The limiting mechanism includes a limiting seat 14 fixedly connected to the bottom of the top cover 1. A rotating ring 15 is rotatably limited on the outer wall of the limiting seat 14. Multiple telescopic rods 16 are fixedly connected to the bottom of the rotating ring 15, and each of the telescopic rods 16 has a fixed ring 17 passing through its bottom end. By setting the limiting seat 14 fixedly connected to the bottom of the top cover 1, and providing a rotating groove on its outer wall, the rotating ring 15 can be limited to rotate. The telescopic rods 16 are evenly distributed at the bottom of the rotating ring 15. 6. The position of the rotating ring 15 is limited, and the extension and retraction of the telescopic rod 16 in the corresponding hole of the fixed ring 17 can be flexibly adjusted according to the vehicle's riding status to prevent the components from separating from the frame due to excessive bumps. When riding on a flat road, the telescopic rod 16 maintains a relatively stable length, keeps the structure compact, and ensures the vehicle rides smoothly. When encountering complex road conditions such as speed bumps and potholes, the vehicle tilts or vibrates more, and the telescopic rod 16 can extend or shorten in time, automatically adjusting the support angle and force to ensure the stability of the vehicle's center of gravity and prevent dangerous situations such as tipping over, thus providing comprehensive protection for riding safety.

[0027] In addition, such as Figure 2 and Figure 4 As shown, a shock-absorbing mechanism is provided at the bottom end of the fixed ring 17. The shock-absorbing mechanism includes a piston rod 19 fixed to the bottom end of the fixed ring 17, a shock-absorbing spring 18 sleeved on the outer wall of the piston rod 19, the top end of the shock-absorbing spring 18 fixedly connected to the bottom end of the fixed ring 17, a bottom fixed ring 20 fixedly connected to the bottom end of the piston rod 19, a shock-absorbing spring 18 fixedly connected to the outer ring of the top end of the bottom fixed ring 20, and a connecting bearing 21 fixedly connected to the bottom end of the bottom fixed ring 20. The piston rod 19 and the shock-absorbing spring 18 sleeved on its outer wall... This allows the shock absorber to quickly move up and down within the fixed ring 17 when the vehicle encounters road bumps. The shock absorber 18 then effectively buffers the vibration energy through compression and rebound. The bottom fixed ring 20 further enhances the stability of the shock absorber 18 installation, while the connecting bearing 21 connected to its bottom end allows the component to quickly adjust its direction, enabling the shock absorber 18 to buffer vibration from the optimal angle, greatly improving the shock absorption effect and riding comfort, and effectively reducing the fatigue of the rider caused by vibration.

[0028] And, as Figure 1 and Figure 3As shown, a connecting mechanism is provided at the top of the top cover 1. The connecting mechanism includes a top fixing port 2 fixed to the top of the top cover 1. A through rod 3 is rotatably connected to the inner wall of the top fixing port 2. Multiple limiting blocks 4 are sleeved on both ends of the outer wall of the through rod 3. Two connecting bracket plates 5 are sleeved on the outer wall of the through rod 3, and the two connecting bracket plates 5 are located between the limiting blocks 4. A through port 6 is fixedly connected to the end of the two connecting bracket plates 5 away from the through rod 3. A fixing arm 7 is fixedly connected to one side of the outer wall of the top cover 1. A fixing port 8 is fixedly connected to the end of the fixing arm 7 away from the top cover 1. A rotating ball 9 is fixedly connected to the bottom end of the fixing port 8. A sleeve 10 is sleeved on the outer wall of the rotating ball 9. A fixing plate 11 is fixedly connected to the bottom end of the sleeve 10. The bottom end of the fixing plate 11 is fixed. A rotating joint 12 is connected, and a connecting arm 13 is rotatably connected to the inner wall of the rotating joint 12. By setting a top fixing port 2 at the top of the top cover 1, a flexible rotation space is provided for the through rod 3. Multiple limiting blocks 4 are sleeved on both ends of the outer wall of the through rod 3, which act as precise positioning devices to accurately limit the position of components such as the connecting frame plate 5. The outer hub passes through the through port 6 through bolts and other connecting parts, which can tightly connect the shock absorption support component with the bicycle frame and hub, ensuring that all components work together during vehicle operation, making it more stable and reliable. A fixing arm 7 on one side of the outer wall of the top cover 1 is connected to the top cover 1 at one end and connected to the rotating ball 9 through a fixing port 8 at the other end. The rotating ball 9 is rotatably connected inside the sleeve 10, allowing the fixing arm 7 to rotate flexibly relative to the sleeve 10. The fixing plate 11 at the bottom of the sleeve 10 is connected to the rotating joint 12. The connecting arm 13 rotatably connected inside the rotating joint 12 is used to connect with the frame. When the bicycle is folded, the connecting arm 13 is rotated by the rotating joint 12. With the flexible rotation of the rotating ball 9 and the sleeve 10, the shock absorption support component and the frame can be easily folded, which greatly improves the portability of the bicycle.

[0029] In this embodiment, when the electric bicycle is in motion, the limiting seat 14 is fixed to the bottom of the top cover 1, providing a base for the rotation of the rotating ring 15. On a flat road, the vehicle moves smoothly, the rotating ring 15 remains relatively stationary, and the telescopic rod 16 maintains a stable length, supporting the upper components to ensure a compact vehicle structure and smooth driving. Once encountering complex road conditions, the vehicle tilts or the vibration amplitude increases, the rotating ring 15 will rotate around the limiting seat 14. At the same time, the telescopic rod 16 senses the vibration and angle change. Based on its telescopic characteristics, the telescopic rod 16 extends or shortens in time within the corresponding hole of the fixing ring 17, thereby automatically adjusting the support angle and force, dynamically adjusting the vehicle's center of gravity, and preventing dangerous situations such as rollover. When the vehicle encounters road bumps during driving, the vibration is transmitted to the shock-absorbing support assembly through the frame. Under the action of vibration, the fixing ring 17 drives the piston rod 19 to move up and down. The shock-absorbing spring 18 sleeved on the outer wall of the piston rod 19 is compressed or rebounds accordingly, using its elastic potential energy to buffer the vibration. The bottom fixing ring 20 strengthens the shock absorption. The shock absorber spring 18 provides stable installation, while the connecting bearing 21 enables the entire assembly to rotate flexibly when in contact with the ground. The connecting bearing 21 allows the assembly to quickly adjust its direction, ensuring that the shock absorber spring 18 always buffers vibrations from the optimal angle. The shock absorber support assembly is tightly connected to the bicycle frame through the through-hole 6 at the end of the connecting frame plate 5 away from the through rod 3, via the connecting piece between the frame and the hub. The fixing arm 7 on one side of the outer wall of the top cover 1 is connected to the top cover 1 at one end and to the rotating ball 9 at the other end via the fixing port 8. The rotating ball 9 is nested inside the sleeve 10, allowing the fixing arm 7 to rotate flexibly relative to the sleeve 10. When the bicycle needs to be folded, the user operates the rotating joint 12 to rotate the connecting arm 13, and the fixing arm 7 then drives the top cover 1 and the entire shock absorber support assembly to fold relative to the frame. The cooperation between the rotating ball 9 and the sleeve 10 ensures that the fixing arm 7 rotates flexibly, realizing convenient folding of the bicycle and improving the portability of the vehicle in different scenarios, making it convenient for users to carry the bicycle on buses, subways, or put it in the trunk of a car.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
