The invention provides a rear shock-proof frame structure of a bicycle. The rear shock-proof frame structure comprises a frame body, a rear upper fork, a rear lower fork and a shock-proof connecting rod. And one end of the rear upper fork is rotationally connected with the frame body. One end of the rear lower fork and the other end of the rear upper fork are used for being in transmission fit with a first rotating shaft of a rear wheel. The shock-proof connecting rod is located below the rear upper fork and rotationally connected with the frame body, and one end of the shock-proof connecting rod is movably connected with the other end of the rear lower fork. One end of the shock absorber is rotationally connected with the frame body, and the other end of the shock absorber is rotationally connected with the other end of the shock absorption connecting rod. When the bicycle is ridden, a person steps on the pedals, the chain drives the rear wheel to descend, the rear wheel drives the shock-proof connecting rod to rotate through the cooperation of the rear upper fork and the rear lower fork, the shock-proof connecting rod pushes the shock absorber to rebound, the bicycle frame body ascends upwards and counteracts one above the other, it is guaranteed that the bicycle frame body keeps stable in the riding process, and the riding quality of the bicycle is improved. The moving range of the frame body is reduced, the unloading force is reduced, and the riding efficiency is improved.
本发明提供一种自行车后避震车架结构,包括车架本体、后上叉、后下叉及避震连杆。后上叉的一端与车架本体转动连接。后下叉的一端及后上叉的另一端均用于与后轮的第一转轴传动配合。避震连杆位于后上叉的下方,并与车架本体转动连接,避震连杆的一端与后下叉的另一端活动连接。避震器的一端与车架本体转动连接,避震器的另一端与避震连杆的另一端转动连接。本申请中的自行车后避震车架结构在骑行的时候,人踩动脚踏,链条带动后轮往下降,后轮通过后上叉及后下叉配合带动避震连杆转动,避震连杆推动避震器回弹,使得车架本体往上升,一上一下互相抵消,保证骑行过程中车架本体保持平稳,车架本体的移动幅度减小,卸力减少,骑行效率提高。
