The invention discloses a locking mechanism, a battery pack, an electric vehicle, a locking method and an unlocking method.The locking mechanism is used for locking the battery pack on the electric vehicle, the locking mechanism comprises a locking assembly and a traction assembly, the locking assembly is in transmission connection with the traction assembly, the locking assembly comprises a rotating buckle, a clamping groove is formed in the rotating buckle, and the rotating buckle is connected with the traction assembly; the traction assembly is used for driving the rotating buckle to be switched from the closed state to the open state while the external equipment lifts the battery pack, so that the battery pack is unlocked relative to the electric vehicle. The locking mechanism drives the rotating buckle of the locking assembly to rotate through the traction assembly when external equipment is lifted or a battery pack is placed, so that a corresponding structure, matched with the rotating buckle, on the electric vehicle leaves or enters a clamping groove of the rotating buckle, and the battery pack is unlocked or locked relative to the electric vehicle. An extra driving source does not need to be arranged at the vehicle end, the structure is light and handy, cost is low, and popularization and use of rapid battery replacement of the electric vehicle are facilitated under the condition that use of the electric vehicle is met.
本发明公开了一种锁止机构、电池包、电动车辆、锁止方法和解锁方法,其用于将电池包锁止于电动车辆上,锁止机构包括锁止组件和牵引组件,锁止组件与牵引组件传动连接,锁止组件包括旋转卡扣,旋转卡扣上设有卡槽,牵引组件用于在外部设备抬升电池包的同时带动旋转卡扣由封闭状态切换至开启状态,以使电池包相对于电动车辆解锁。锁止机构通过牵引组件在外部设备抬升或放置电池包时带动锁止组件的旋转卡扣旋转,以使得与旋转卡扣配合的电动车辆上的对应结构离开或进入旋转卡扣的卡槽,使电池包相对电动车辆进行解锁或锁止,无需在车端设置额外的驱动源,在满足电动车辆使用的情况下,结构轻巧,成本低廉,有利于电动车辆快速换电的推广使用。
