[0024] like Figure 1 As shown, this utility model proposes a high-strength electric bicycle frame, including a supporting crossbar 1 and a frame structure located on one side of the outer wall of the supporting crossbar 1. The frame structure includes a fixing rod 4 fixed to one end of the supporting crossbar 1, and a head frame 3 is fixedly connected to the end of the supporting crossbar 1 away from the fixing rod 4. A connecting frame rod 2 is fixedly connected to the end of the outer wall of the head frame 3 away from the supporting crossbar 1. A through shaft 5 is fixedly connected to the end of the connecting frame rod 2 away from the head frame 3. The top end of the through shaft 5 is fixedly connected to the fixing rod 4, and bearing sleeves 6 are fitted on both ends of the outer wall of the through shaft 5. Bearing blocks 7 are fixedly connected to one side of the outer wall of the two bearing sleeves 6. Two frame connecting rods 8 are fixedly connected to one side of the bearing blocks 7. A hub connecting frame 9 is fixedly connected to the end of the two frame connecting rods 8 away from the bearing blocks 7. A hub connecting plate 10 is fixedly connected to one side of the hub connecting frame 9. A diagonal brace 11 is fixedly connected to the end of the hub connecting plate 10 away from the hub connecting frame 9. By setting the supporting crossbar 1... One end is welded to the fixing rod 4, providing solid longitudinal support for the frame. The through shaft 5 is seamlessly connected to the fixing rod 4, ensuring efficient and smooth force transmission. The bearing sleeves 6 fitted on both ends of its outer wall make the wheel rotate more flexibly during driving and reduce energy loss. The bearing block 7 connected to one side of the outer wall of the bearing sleeve 6 acts as a force transfer hub, evenly distributing the force from the frame connecting rod 8 to ensure structural stress balance. The wheel hub connecting frame 9 connected to the other end of the two frame connecting rods 8 has a triangular structure design that enhances the connection stability with the wheel hub and can effectively resist the impact from the road surface. The wheel hub connecting plate 10 connected to one side of the wheel hub connecting frame 9 plays a precise positioning role for the wheel hub, ensuring the dynamic balance of the wheel when rotating at high speed. The end of the wheel hub connecting plate 10 away from the wheel hub connecting frame 9 is connected to the diagonal brace 11. The diagonal brace 11 is arranged in an inclined shape and together with other components, it forms a stable triangular support system, which greatly improves the load-bearing capacity of the frame in the vertical and horizontal directions.

[0025] In addition, such as Figure 2 , Figure 3 and Figure 4As shown, a fixed base 12 is fixedly connected to the outer wall of the fixed rod 4. A support mechanism is provided on one side of the fixed base 12. The support mechanism includes a connecting block 13 fixed to one side of the fixed base 12. Multiple rotating joints 14 are fixedly connected to one side of the outer wall of the connecting block 13. A through shaft 15 passes through one side of the multiple rotating joints 14. A connecting arm 16 is rotatably connected to the inner wall of the through shaft 15. A connecting bearing 17 is fixedly connected to one end of the multiple connecting arms 16 away from the through shaft 15. A through shaft 29 passes through one side of the multiple connecting bearings 17. A support arm 20 is rotatably connected to the middle position of the through shaft 29. Fixed plates 18 pass through both ends of the outer wall of the through shaft 29. Diagonal braces are fixedly connected to one end of the two fixed plates 18. A connecting section 21 is rotatably connected to one end of the support arm 20 away from the through shaft 19. Two connecting rods 22 are fixedly connected to one side of the outer wall of the connecting section 21. A fixing section 23 is fixedly connected to one end of the two connecting rods 22 away from the connecting section 21. One side of the fixing section 23 is fixedly connected to the fixing rod 4. A connecting plate 24 is fixedly connected to one side of the outer wall of the support arm 20. A spring buffer rod 25 is rotatably connected to one side of the outer wall of the connecting plate 24. A fixing support 26 is rotatably connected to one end of the spring buffer rod 25 away from the support arm 20. The inner wall of the fixing support 26 is fixedly connected to the outer wall of the fixing rod 4. By setting a fixing seat 12 on the outer wall of the fixing rod 4 as the starting connection point of the support mechanism, the connection firmness with the fixing rod 4 is enhanced. Connecting block 13 Fixed to one side of the fixed base 12, multiple rotating joints 14 are distributed on one side of the outer wall of the connecting block 13. The rotating joints 14 adopt a rotating design to adapt to the force requirements in different directions, making the connecting arm 16 move more freely during movement. One end of the connecting arm 16 is rotatably connected to the inner wall of the through shaft 15, and smooth rotation is achieved through bearing cooperation. When the frame is under stress, the angle can be flexibly adjusted to disperse the impact force. The connecting bearing 17 connected to the other end of the connecting arm 16 further improves the flexibility and stability of rotation. The support arm 20 can effectively share the load of the frame in the vertical direction. The fixing plates 18 penetrating both ends of the outer wall of the through shaft 19 play a role in limiting and reinforcing the support arm 20, and at the same time, transfer the force of the support arm 20 to the diagonal brace 11, enhancing the overall structure. To ensure stability, the end of the support arm 20 away from the through shaft 19 is connected to two connecting rods 22 via a connecting joint 21, allowing for multi-directional rotation. This enables the connecting rods 22 to better adapt to the movement of the support arm 20. The other end of the connecting rod 22 is connected to a fixed joint 23, which is fixed to a fixed rod 4, further strengthening the connection between the support mechanism and the frame body. The connecting plate 24 connected to one side of the outer wall of the support arm 20 serves as the connection base for the spring buffer rod 25. During vehicle operation, it effectively absorbs vibrations caused by road bumps, providing a comfortable riding experience for the rider. The other end of the spring buffer rod 25 is connected to a fixed support 26, which is fixed to the outer wall of the fixed rod 4, providing support and limiting for the spring buffer rod 25, ensuring its stability during operation.

[0026] In this embodiment, when the electric bicycle encounters potholes or uneven road surfaces, the various components of the frame respond rapidly. The spring buffer rod 25 in the support mechanism absorbs the vibration energy first, converting the vibration into elastic potential energy through the compression and rebound of the spring and gradually releasing it, reducing the impact on the frame and the rider. At the same time, components such as the support arm 20 and the connecting arm 16 work together to adjust their angles, evenly distributing the external force to the overall frame structure, ensuring that the frame remains stable under complex road conditions, and providing the rider with a safe and comfortable riding experience.

[0027] 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.
