Compared with traditional fuel vehicles, new energy buses have the advantages of low operating costs and low pollution. For existing new energy buses with fast battery swapping, the operation of replacing the battery pack is rather cumbersome, requiring multiple steps to unlock the connection device. Moreover, due to the large weight of the battery pack, the battery swapping efficiency of new energy buses is relatively low. Summary of the Invention
