The invention discloses an aluminum alloy integrally-formed foldable electric vehicle frame. A main frame body is hinged to an auxiliary frame body. The auxiliary frame is provided with a first rear wheel frame connecting hole, and the connecting plate is provided with a shock absorber connecting hole, an auxiliary frame connecting hole and a second rear wheel frame connecting hole. The connecting plate is installed on the connecting plate installation upper arm of the auxiliary frame through the auxiliary frame connecting hole, the second rear wheel frame connecting hole of the connecting plate is connected with the upper end of the rear wheel frame in a pivoted mode, the lower end of the rear wheel frame is connected with the first rear wheel frame connecting hole of the auxiliary frame in a pivoted mode, and the main frame, the auxiliary frame, the connecting plate and the rear wheel frame are made of aluminum alloy in an integrated casting molding mode. The connecting plate is installed on the auxiliary frame, the second rear wheel frame connecting hole of the connecting plate is in pivot joint with the rear wheel frame, and therefore the rear wheel frame is not fixedly connected with the auxiliary frame, and the electric bicycle can have good shock absorption capacity. Aluminum alloy is integrally cast and formed, only simple polishing is needed, a complete frame is formed through screw connection and fastening connection, and time is saved in machining.
本发明公开了铝合金一体成型可折叠电动车车架,其主车架与副车架铰接;副车架设有第一后轮架连接孔,连接板上分别开设有避震器连接孔、副车架连接孔和第二后轮架连接孔;连接板通过副车架连接孔安装在副车架的连接板安装上臂上,连接板的第二后轮架连接孔与后轮架上端枢接,后轮架下端与副车架的第一后轮架连接孔枢接,主车架、副车架、连接板和后轮架采用铝合金一体浇铸成型制造,使用时,连接板安装在副车架上,连接板的第二后轮架连接孔与后轮架枢接,因此后轮架与副车架并不是固定连接的,所以可以让电动自行车具有较好的避震能力;采用铝合金一体浇铸成型,只需简单打磨,再通过螺钉连接紧固连接形成一个完整的车架,加工省时。
