Compared with the mode of supplementing electric energy by connecting charging equipment such as a charging pile, the battery replacement can realize the supplementing of electric energy faster, and the electric energy is also supplemented by the mode of battery replacement at present. However, in the mode of replacing the battery, not only the electric energy output end of the battery and the electric energy input end of the vehicle are required to be connected, but also the water-cooling pipeline of the battery and the water-cooling pipeline of the electric equipment are required to be connected, however, the water-cooling pipeline of the battery and the water-cooling pipeline of the electric equipment in the prior art are not easy to align, the connection difficulty is high, and the connection parts of the two water-cooling pipelines are easy to deform, so that the tightness is poor.
