The invention relates to the technical field of electric vehicles, in particular to a frame structure and an electric vehicle. The bicycle frame structure comprises a bicycle frame body, a saddle and a saddle lock assembly, the bicycle frame body comprises a first bicycle frame and an extended bicycle frame, and the first bicycle frame is detachably connected with the extended bicycle frame; the saddles comprise a first saddle and a second saddle, and the length of the first saddle is smaller than that of the second saddle; the saddle lock assembly comprises a locking piece and a lock catch, when the locking piece is installed on the first bicycle frame, the first bicycle frame is separated from the extended bicycle frame, and the lock catch is installed on the first saddle, and when the locking piece is installed on the extended bicycle frame, the first bicycle frame is connected with the extended bicycle frame, and the lock catch is installed on the second saddle. And the locking piece can be locked with or unlocked from the lock catch so as to lock or unlock the extended frame and the second saddle. The length of the frame main body is changed through connection and separation of the first frame and the extended frame, so that the frame can adapt to saddles with different lengths, the universality of the frame main body is improved, the design investment is reduced, and the manufacturing cost is reduced.
本发明涉及电动车技术领域,尤其涉及车架结构及电动车。该车架结构包括车架主体、鞍座和鞍座锁组件,车架主体包括第一车架和延长车架,第一车架与延长车架可拆卸连接;鞍座包括第一鞍座和第二鞍座,第一鞍座的长度小于第二鞍座的长度;鞍座锁组件包括锁紧件和锁扣,当锁紧件安装于第一车架,第一车架与延长车架分离,锁扣安装于第一鞍座,当锁紧件安装于延长车架,第一车架与延长车架连接,锁扣安装于第二鞍座,锁紧件能够与锁扣锁紧或打开用于将延长车架和第二鞍座锁紧或打开。通过第一车架和延长车架的连接和分离改变车架主体的长度,进而适应不同长度的鞍座,提高了车架主体的通用性,减少设计投入,降低制造成本。
