Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a wire harness retracting and releasing device for a charging pile. Background Art

[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, the number of cars in cities is increasing. Among them, the number of electric vehicles is gradually increasing. The charging power of electric vehicle charging piles is also increasing, and the corresponding gun wire is getting heavier. Moreover, the charging gun wire is too heavy, which makes it very inconvenient to lift the charging gun for charging by manpower. Therefore, it is necessary to use a charging gun wire retracting device to reel the charging gun wire.

[0003] However, in actual use, if the charging cable is too long, it will easily drag on the ground and get stuck with dust, stones and other objects. When the stones are rolled into the retracting device, it may cause the retracting device to malfunction and become unable to be used normally. In severe cases, it may scratch the outer skin of the charging cable and cause a safety accident. Utility Model Content
