The invention discloses a locking mechanism for a battery pack, a quick-change bracket assembly and an electric vehicle. The locking mechanism comprises a lock base provided with an opening and a cavity extending from the opening; the spring bolt can rotate relative to the lock base so as to change between an unlocking state and a locking state, and when the spring bolt is in the locking state, the spring bolt can prevent the lock shaft from leaving the cavity from the opening; the reset component is arranged on the lock base, acts on the spring bolt and is used for enabling the spring bolt to rotate in the locking direction so that the spring bolt can be reset to the locking state from the unlocking state. The reset component is arranged, so that the spring bolt can be conveniently reset from the unlocking state to the locking state, the battery pack is convenient to install and lock, under the action of the reset component, the spring bolt cannot be easily changed into the unlocking state, and locking is more reliable; and the locking mechanism can provide a secondary locking or locking protection function for the battery pack, and is used for preventing the battery pack from falling off when the locking of the existing device fails, so that the safety performance is improved.

    本发明公开了一种用于电池包的锁止机构、快换支架组件以及电动车。锁止机构包括有:锁基座,设有一开口以及自开口延伸的一空腔;锁舌,能够相对于锁基座旋转以在一解锁状态以及一锁止状态之间变化,当锁舌处于锁止状态时,锁舌能够阻止锁轴从开口离开空腔;以及复位部件,设于锁基座且复位部件作用于锁舌,复位部件用于使得锁舌沿一锁止方向旋转以从解锁状态复位到锁止状态。本发明设置复位部件便于锁舌从解锁状态复位到锁止状态,使得电池包安装、锁止均方便,且在复位部件作用下,锁舌不会轻易变化为解锁状态,锁止更加可靠;锁止机构可以为电池包提供二级锁止或锁止保护功能,在现有的装置锁止失效时用于防止电池包掉落,提高安全性能。
