The invention discloses a liquid cooling connecting device convenient to lock, a battery pack and an electric automobile, and the liquid cooling connecting device convenient to lock comprises a mounting seat which is arranged in a containing cavity at the bottom of the electric automobile or on the battery pack; the connecting valve is fixed on the mounting seat, one end of the connecting valve is connected with the liquid supply device, and the other end of the connecting valve is used for being connected with a liquid cooling pipeline; a moving part is arranged on the mounting seat, and drives the connecting valve to synchronously move when the lock shaft of the battery pack horizontally moves along an L-shaped lock groove in the bottom of the electric vehicle; the mounting base comprises a moving plate, and the moving part is arranged on the moving plate so that the connecting valve can be movably connected relative to the moving plate. The problem that the connection valve is unstable in connection due to the movement of the battery pack in the locking process is solved through the follow-up mode of the connection valve, and the safety and stability of the liquid cooling connection device convenient to lock are greatly improved. The connecting valve moves on the moving plate in the set direction through the moving part, the connecting accuracy is guaranteed, and the connecting efficiency is improved.

    本发明公开了一种便于锁止的液冷连接装置、电池包和电动汽车,便于锁止的液冷连接装置包括:安装座,设置在电动汽车底部的容纳腔内或者电池包上;以及连接阀,固定于安装座上,连接阀的一端与供液装置相连接,另一端用于与液冷管路相连接;安装座上设有移动部件,移动部件在电池包的锁轴沿电动汽车底部的L型锁槽水平移动时驱动连接阀同步移动;安装座包括移动板,移动部件设于移动板上以实现连接阀相对移动板的移动连接。通过连接阀随动的方式解决了因锁止过程中电池包移动导致的连接阀连接不稳定等问题,大大提高了便于锁止的液冷连接装置的安全稳定性。通过移动部件使得连接阀在移动板上沿既定的方向移动,保证连接的准确性,提高连接效率。
