[0002] An electric vehicle refers to a vehicle driven by an electric motor, which has many advantages: First, it can reduce air pollution and address climate change; Second, the efficiency of an internal combustion engine is lower than that of an electric motor, which can reduce energy consumption and improve energy efficiency; In addition, the fuel cost of an electric vehicle is usually lower than that of a traditional vehicle because electricity is cheaper than gasoline or diesel; Finally, the electric motor provides instantaneous torque, providing brisk acceleration and a smoother driving experience, running quietly, creating a quieter driving environment than an internal combustion engine vehicle. However, the energy stored per unit weight of the battery pack is too little, the cruising range is limited, and the charging speed is slow. In order to improve the use efficiency of electric vehicles, a battery swapping mode is usually adopted to quickly replace the battery pack of the electric vehicle so that the electric vehicle can be put into use again.

[0003] Currently, the battery swapping of electric vehicles generally adopts hoisting the battery pack from above, which has certain limitations on the usage conditions, occupies a large space during the usage process, and, during the hoisting process, the battery pack is prone to shaking, which is likely to damage the battery pack, and at the same time, it is difficult to accurately adjust the position of the battery pack, which is not conducive to the replacement of the battery pack. Summary of the Utility Model

Drive the rotating shaft 11 to rotate through the motor 10, and wind up the steel cables 15 on both sides on the same side of the winding disc 12 so that the battery pack is separated from the vehicle body 1 or the battery pack below. Then, adjust the position of the moving frame 7 in the slide rail 6 so that the battery pack extends above the battery pack installation position of the electric vehicle. Finally, unwind the steel cable 15 again to complete the battery swapping operation of the electric vehicle; during this process, the space occupied by the equipment during operation is small, and it is suitable for various environments; in addition, during use, when the position of the battery pack changes, the positioning block 17 will move in the groove 16 to adapt to the position of the battery pack.
