[0002] Charging piles are important basic supporting charging facilities for electric vehicles. With the rapid development of new energy vehicle charging, charging piles have gradually developed from floor-standing charging piles to wall-mounted or ceiling-mounted charging cabinets. During the operation of electric vehicle charging, people need to remove the charging gun head from the charging cabinet, extend the charging cable, and connect the charging gun head to the charging port of the electric vehicle. After charging, the operator needs to tidy up the charging cable and then put the charging gun head back into the charging cabinet.

[0003] Due to the special installation location, the existing suspended charging cabinets are not convenient to store by manual winding. The charging cable is thick and heavy. If the charging cable is exposed to the outside for a long time, it will be dragged on the ground.
