The invention discloses a locking mechanism, a locking assembly, a quick-change support assembly and an electric vehicle. The lock base is provided with an opening and a cavity extending from the opening, and the opening is used for allowing a lock shaft installed on the battery pack to enter the cavity; the lock tongue can rotate relative to the lock base so as to change between an unlocking state and a locking state, the side, facing the lock shaft, of the lock tongue is sequentially provided with a first locking part and a second locking part in the locking direction, the first locking part is used for limiting the lock shaft from falling off from the lock base, and when the lock tongue is in the locking state, the second locking part is used for limiting the lock shaft from falling off from the lock base. The second locking part is used for limiting the lock shaft to move towards the first locking part so as to prevent the lock shaft from leaving the cavity from the opening. According to the locking device, the first locking part is used for roughly limiting the locking shaft, the second locking part is used for finely limiting the locking shaft, the locking shaft can be reliably locked through the cooperation of the first locking part and the second locking part, the locking stability is obviously improved, and then the battery replacement reliability of the electric vehicle is improved.

    本发明公开了一种锁止机构、锁止组件、快换支架组件及电动汽车。锁止机构包括有:锁基座,具有开口以及自开口延伸的空腔,开口用于供安装于电池包的锁轴进入空腔;锁舌,能够相对于锁基座旋转以在解锁状态以及锁止状态之间变化,锁舌用于朝向锁轴的一侧沿锁止方向依次具有第一锁止部和第二锁止部,第一锁止部用于限制锁轴自锁基座上掉落,当锁舌处于锁止状态时,第二锁止部用于限制锁轴朝向第一锁止部运动,以阻止锁轴从开口离开空腔。第一锁止部对锁轴进行粗限位,第二锁止部对锁轴进行精限位,通过第一锁止部和第二锁止部的配合能够较为可靠地对锁轴进行锁止,较为显著地提高了锁止的稳定性,进而有利于提高电动汽车的换电可靠性。
