The invention discloses a damping connecting device, a bicycle frame, a bicycle and an electric bicycle. The front support, the rear support and the seat support of the frame are connected through the damping connecting device. The damping connecting device comprises a front connector, a rear connector, a middle connector and a buffering piece. The front connector and the middle connector are rotationally connected through a first pin shaft, the middle connector and the rear connector are rotationally connected through a second pin shaft, and the front connector and the rear connector are rotationally connected through a third pin shaft. The front portion of the middle connector is provided with a front limiting piece with a front limiting face facing backwards, the front connector or the rear connector is provided with a rear limiting piece with a rear limiting face facing forwards, at least one part of the front limiting face and at least one part of the rear limiting face are planes, and the buffering piece is limited between the front limiting face and the rear limiting face. And when the front joint or the rear joint rotates relative to the middle joint, the deformation is realized. On the premise that the frame has good damping and buffering performance, the structure is simplified, meanwhile, the frame has good structural stability, and light weight of the frame is facilitated.

    本发明公开了一种减震连接装置、车架、自行车及电动车。减震连接装置将车架的前支架、后支架及座位支架连接。减震连接装置包括:前接头,后接头,中接头和缓冲件。前接头和中接头通过第一销轴转动连接,中接头和后接头通过第二销轴转动连接,前接头和后接头通过第三销轴转动连接;中接头的前部设有具有朝向后方的前限位面的前限位件,前接头或后接头上设有具有朝向前方的后限位面的后限位件,前限位面和后限位面的至少一部分为平面,缓冲件被限制在前限位面和后限位面之间,以在前接头或后接头相对中接头转动时变形。该车架在具有较好的减震缓冲性能的前提下,简化结构,同时具有较好的结构稳定性,利于车架的轻量化。
