Description

Technical Field

[0001] This utility model relates to an electric bicycle, specifically to a shock-absorbing linkage structure for an electric bicycle. Background Technology

[0002] In the design of electric bicycles, the performance of the shock absorption system directly affects riding comfort and safety. Many electric bicycles use shock absorbers that fail to effectively absorb and cushion vibrations and impacts from the road surface, causing vibrations to be transmitted to the frame and body during riding, affecting rider comfort. This is particularly noticeable on uneven roads, easily causing rider fatigue and discomfort. Furthermore, many shock absorbers have a protruding structure and lack aesthetically pleasing design, affecting the overall visual appeal of the electric bicycle and potentially reducing consumer acceptance of the product.

One end of the shock absorber body is rotatably mounted on the frame body through a torsion spring structure, and the other end of the shock absorber body is rotatably connected to the linkage structure through a torsion spring structure. Through the cooperation between the shock absorber body and the linkage structure, the shock absorption effect is achieved.

[0009] As a preferred technical solution, the electric vehicle frame is provided with a shock absorber mounting position, and the shock absorber mounting position is between the first rotation position and the second rotation position;

[0010] One end of the shock absorber body is rotatably mounted on the shock absorber mounting position via a torsion spring structure, and the other end of the shock absorber body is rotatably mounted on the rotating seat of the connecting rod structure via a torsion spring structure.

[0011] As a preferred technical solution, the torsion spring structure includes torsion spring mounting grooves disposed at both ends of the shock absorber body and a torsion spring body, wherein the outer ring of the torsion spring body is fixed in the torsion spring mounting groove;

[0012] Both the shock absorber mounting position and the rotating seat are equipped with connecting pins, and the inner ring of the torsion spring body is connected to the connecting pins, thereby achieving the effect of shock absorber body rotation buffering, which increases the buffering effect when the rear fork is subjected to vibration.

[0013] As a preferred technical solution, the rotating ends of the rotating seat, connecting rod, and fixed rod all achieve rotation through bearings.
