The reset structure can be set near the movable rotating shaft 52, and connected to the movable support arm 51 and the proximity switch 56 respectively. When the proximity switch 56 detects that there is no external force and the movable support arm 51 is not in a horizontal support state, the reset structure is controlled to restore the movable support arm 51 to a horizontal support state.

[0080] Optionally, when the preset angle between the movable supporting arm 51 and the horizontal direction is less than 45 degrees, gravity can be used to enable the movable supporting arm 51 to automatically restore to a horizontal supporting state when no external force is applied.

[0081] The present application provides a specific embodiment. After the battery swap tool disassembles the exhausted battery pack, it stops under the battery rack. The exhausted battery can be lifted by the lifting function of the battery swap tool itself or by a palletizer. When the exhausted battery pack contacts the movable support arm 51, the movable support arm 51 flips upward around the movable shaft 52, the exhausted battery pack continues to rise, the support arm naturally falls, and returns to a horizontal state. The exhausted battery pack falls and is placed on the movable support arm 51 to complete the placement action. In this process, the buffer 55 plays a buffering role, the limit structure 57 plays a limit role, and the proximity switch 56 is used to detect whether the movable support arm 51 is in a horizontal support state.

[0082] The battery replacement tool can obtain a new fully charged battery pack through a palletizer, a conveyor line and other devices to complete the subsequent battery installation process. At the same time, the depleted battery pack placed on the movable support arm 51 is moved off the support arm by the palletizer and placed on the upper fixed load-bearing structure 3 or other battery bracket for battery charging.
