The invention discloses a liquid cooling connecting device with a floating function, a battery pack and an electric automobile, and the liquid cooling connecting device 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; the mounting base comprises a mounting plate fixed to the battery pack or in a containing cavity in the bottom of the electric vehicle and a moving mechanism capable of stretching and moving in the circulation direction of the circulation channel relative to the mounting plate, and the connecting valve is fixedly arranged on the moving mechanism. According to the liquid cooling connection device, the movement amount of the connection valve is increased, the connection valve moves more stably, the connection stability of the connection valve is guaranteed, the leakage phenomenon of cooling liquid is effectively avoided, and the installation stability of the liquid cooling connection device is greatly improved. And the problem of unstable connection of the connecting valve caused by factors such as vehicle vibration and the like is solved in a follow-up mode of the connecting valve.

    本发明公开了一种具有浮动功能的液冷连接装置、电池包和电动汽车,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;安装座包括固定于电池包上或者电动汽车底部的容纳腔内的安装板以及相对于安装板可沿流通通道的流通方向伸缩移动的移动机构,连接阀固定设于移动机构上。增大了连接阀的移动量,且连接阀移动更加稳定,保证了连接阀连接的稳定性,有效避免了发生冷却液的渗漏现象,大大提高了液冷连接装置的安装稳定性。通过连接阀随动的方式解决了车辆震动等因素导致的连接阀连接不稳定等问题。
