The invention discloses a rear wheel and chain wheel folding mechanism applied to an electric bicycle, which comprises a hanging bracket, a rear wheel fork frame is arranged below the hanging bracket, one end of the hanging bracket and one end of the rear wheel fork frame are provided with a first rotating shaft, the rear wheel fork frame and the hanging bracket are connected through the first rotating shaft, one end of the rear wheel fork frame is provided with a rear wheel, and the other end of the rear wheel fork frame is provided with a chain wheel. A rear wheel shaft is arranged on one side of the rear wheel; the folding electric bicycle has the beneficial effects that the folding mode is unique and rapid, namely forward rotation and displacement of the rear wheel and upward rotation and displacement of the chain wheel are completed by pressing down one rocker arm rod, the size of the folded bicycle can be effectively reduced, and compared with a traditional folding electric bicycle, the rear wheel can be folded and can be stored in the direction of the bicycle frame main body; the size of the folded vehicle is greatly reduced, and carrying and storage are convenient.

    本发明公开了一种应用于电动自行车的后轮与牙盘折叠机构,包括吊架,所述吊架下方设有后轮叉架,所述吊架与所述后轮叉架一端设有第一转轴,所述后轮叉架与所述吊架通过所述第一转轴连接,所述后轮叉架一端设有后轮,所述后轮一侧设有后轮轴;本发明的有益效果是:折叠方式独特快捷,即通过一个摇臂杆下压,就完成后轮向前,牙盘向上旋转移位,能有效减小车辆折叠后的尺寸,与传统折叠电动自行车相比,可进行后轮折叠,并能使得后轮向车架主体方向进行收纳,极大地减小了车辆折叠后的体积,便于携带与存储。
