The invention discloses a quick-change power battery mounting system, a locking method, an unlocking method and an electric vehicle. The power battery mounting system comprises a quick-change supportand a power battery pack; the quick-change support is connected with a locking mechanism assembly; the locking mechanism assembly comprises a plurality of locking mechanism bodies arranged on the quick-change support, connecting parts connected with the locking mechanism bodies and a secondary locking mechanism; the secondary locking mechanism comprises a sliding assembly and a limiting assembly,and the sliding assembly is fixedly connected with the connecting part; and when the multiple locking mechanism bodies are all in the locking state, the limiting assembly is in the secondary locking state of locking the sliding assembly. According to the scheme, the quick-change support and the quick-change power battery pack can be detachably connected, the reliability of the locking state is improved, and the replacement operation of the quick-change power battery pack is quick.

    本发明公开了一种快换动力电池安装系统、锁止方法、解锁方法及电动汽车,动力电池安装系统包括:快换支架和动力电池包;快换支架上连接锁止机构总成,锁止机构总成包括设置在所述快换支架上的多个锁止机构本体,与多个锁止机构本体连接的连接部件,以及二次锁止机构;二次锁止机构包括滑动组件和限制组件,滑动组件与连接部件固定连接;在多个锁止机构本体均处于锁止状态时,限制组件处于锁止滑动组件的二次锁止状态。本发明的方案,能够实现快换支架与快换动力电池包可拆卸连接,提高了锁止状态的可靠性,快捷快换动力电池包的更换操作。
