Technical Field
[0001] The utility model relates to the technical field of bicycle frames, in particular to an electric bicycle frame with good buffering effect. Background Art
[0002] An electric bicycle is a bicycle equipped with a motor and a battery, which can provide additional power to help the rider ride easily. Especially when climbing slopes or riding long distances, the frame of the electric bicycle is the basic structure of the electric bicycle, carrying the motor, battery, wheels and other components.
[0003] When the existing electric bicycle is riding, the body is buffered only through the buffer structure between the wheel and the rear fork. When the road surface is uneven, it is easy to jolt the rider up, and the shock absorption effect is poor.
[0004] Therefore, we propose an electric bicycle frame with good buffering effect to solve the above problems. Content of the Utility Model

[0007] An electric bicycle frame with good buffering effect, including a bracket, two cross bars are arranged above the bracket, and the two cross bars are fixedly connected with the bracket through two support pipes. The right end of the bracket is rotatably connected with a rear fork. A through hole is jointly arranged through the connecting part of the rear fork and the bracket. Baffles are arranged on the left sides of the two support pipes. The upper and lower ends of the baffle are respectively fixedly connected with the cross bar and the bracket. The left ends of the two cross bars are fixedly connected with the same head tube. The head tube and the baffle are fixedly connected through a support rod. A storage groove is arranged between the two cross bars. A seat plate is arranged on the right side of the storage groove. The seat plate is fixedly connected with both cross bars;
[0008] A buffering mechanism is used to buffer the rear fork and the two support pipes. The buffering mechanism includes a telescopic rod. Connecting plates are fixedly connected to the front and rear sides of the outer side of the telescopic rod. A buffer spring is sleeved outside the telescopic rod. The two ends of the buffer spring are respectively fixedly connected with the two connecting plates. The two ends of the telescopic rod are respectively rotatably connected with the two support pipes and the rear fork through rotating blocks.
[0009] Further, a return plate is fixedly connected between the baffle and the two support pipes.

[0012] Further, an installation slot is provided at the rear side of the lower end of the U-shaped part.
[0013] Further, the two cross bars are fixedly connected by a plurality of connecting rods.
[0014] Compared with the prior art, the beneficial effects of the present utility model are at least as follows:
[0015] By providing a buffer mechanism, when the vehicle body is jolted, the tail fork will rotate relative to the bracket. During the rotation process, the tripod will compress the telescopic rod and the buffer spring, and buffer the vibration force received by the vehicle body through the buffer spring and the telescopic rod, greatly reducing the vehicle body vibration and having a good damping effect on the vehicle body.

[0021] The following will describe the present utility model in detail with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 3, an electric bicycle frame with good buffering effect, including a bracket 1. It should be noted that an installation hole 17 runs through the bracket 1. Above the bracket 1, there are two cross bars 2. The two cross bars 2 are fixedly connected to the bracket 1 through two support pipes 3. The right end of the bracket 1 is rotatably connected to a tail fork 4. It should be noted that an installation slot 20 is provided at the rear side of the lower end of the U-shaped part 18. Further, the tail fork 4 includes a U-shaped part 18 and a triangular support 19. The triangular support 19 is fixedly connected to the U-shaped part 18. It should be noted that a support foot mounting bracket telescopic rod 12 is installed at the lower end of the U-shaped part 18 and is rotatably connected to the triangular support 19. The connection part between the tail fork 4 and the bracket 1 is provided with a through hole 5 in common. On the left side of the two support pipes 3, there is a baffle 6. Specifically, a return plate 16 is fixedly connected between the baffle 6 and the two support pipes 3. It should be noted that the battery pack is installed between the baffle 6 and the support pipe 3, and the battery pack is protected by the return plate 16.
[0023] In the present utility model, the upper and lower ends of the baffle 6 are respectively fixedly connected to the cross bar 2 and the bracket 1. The left ends of the two cross bars 2 are fixedly connected to the same head tube 7. It is worth mentioning that the two cross bars 2 are fixedly connected through multiple connecting rods 21. The head tube 7 is fixedly connected to the baffle 6 through a support rod 8. A storage groove 9 is provided between the two cross bars 2. On the right side of the storage groove 9, there is a seat plate 10. The seat plate 10 is fixedly connected to both cross bars 2;
[0024] During the riding process, the damping effect of the existing electric bicycle is poor. Therefore, a buffering mechanism 11 is provided to buffer the tail fork 4 and the two support pipes 3. The buffering mechanism 11 includes a telescopic rod 12. On the front and rear sides of the outside of the telescopic rod 12, there are fixedly connected connecting plates 13. A buffering spring 14 is sleeved outside the telescopic rod 12. The two ends of the buffering spring 14 are respectively fixedly connected to the two connecting plates 13. The two ends of the telescopic rod 12 are respectively rotatably connected to the two support pipes 3 and the tail fork 4 through rotating blocks 15.
[0025] Through the above technical features, when the vehicle body is jolted, the tail fork 4 will rotate relative to the bracket 1. During the rotation process, the tripod 19 will compress the telescopic rod 12 and the buffering spring 14, and buffer the vibration force received by the vehicle body through the buffering spring 14 and the telescopic rod 12, greatly reducing the vehicle body vibration.
