[0002] With the popularity of electric vehicles, the demand for automatic battery swap stations is increasing. The existing battery swap trolley (also known as transfer trolley) usually adopts a fixed structure platform, and since the battery is generally a cuboid structure, therefore, when the battery swap trolley takes the battery, the length direction of the carrying platform needs to be consistent with the loading direction of the battery in the vehicle chassis, so that the entire battery can be safely placed on the carrying platform of the battery swap trolley. During the placement and transfer process, the battery falls due to the small bearing surface and unstable center of gravity, accordingly, this design has the following shortcomings:
