Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, and more specifically, to an automatic wire-winding auxiliary structure for a charging line of a new energy charging pile. Background Art

[0002] With the vigorous promotion of new energy vehicles, the installation volume of new energy charging piles has also been widely rolled out. In order to extend the service life of the charging cable during use, avoid leakage due to damage to the charging cable during charging, and ensure the safety of charging, the new energy charging pile is usually equipped with an automatic wire-retracting device to promptly recycle the charging cable after charging is completed. For example, the existing Chinese utility model patent with the authorization announcement number CN219856839U, under the interaction of the charging pile cabinet, charging plug, charging cable, fixed cavity, connecting hole, wire-retracting shaft, motor, rotating shaft and protective device, the charging cable can be stored in the fixed cavity of the charging pile cabinet to avoid long-term exposure of the charging cable to the outside world. The motor allows the wire-retracting shaft to store the charging cable in the fixed cavity, which makes it more convenient to store the charging cable without manual work. At the same time, the protective device can protect the outer skin of the charging cable during the storage and movement process. However, in actual use, it was found that due to the lack of corresponding auxiliary structure, the charging cable will inevitably come into contact with the charging pile cabinet during the stretching process. When it is retracted or pulled too quickly, the charging pile cabinet is hard in texture and it is easy to cause scratches on the surface of the charging cable. Due to the lack of a finishing structure for the charging cable, the charging cables are prone to entanglement during the automatic winding process. Utility Model Content
