Embodiment Construction

[0024] This embodiment provides a cable retracting device for retracting and retracting cables. Here, the cable is taken as an example of a charging gun cable (that is, a charging cable). Of course, the cable can also be of other types and uses. Cables, such as communication cables. That is to say, the cable retracting device is not limited to the types of cables.

[0025] The cable retracting device includes a cable fixing part for fixing the charging gun wire and a cable lead-out part for the charging gun wire to lead out. There is a cable retracting mechanism between the cable fixing part and the cable lead-out part, and the cable The retractable mechanism includes a track and a support pulley for winding the charging gun wire. The support pulley guides and moves and is assembled on the track. Then, when the support pulley moves on the track, it can support or release the support pulley arranged on the support pulley. charging gun wire, and change the length of the chargin...

Abstract

The invention relates to a cable winding and unwinding device which comprises a cable fixing part for fixing a cable and a cable leading-out part for leading out the cable. A cable winding and unwinding mechanism is arranged between the cable fixing part and the cable leading-out part, and the cable winding and unwinding mechanism comprises a track and a jacking pulley for winding the cable. The jacking pulley is movably arranged on the track in a guiding mode to jack up or release the cable arranged on the jacking pulley when moving to change the length of the cable portion between the cablefixing part and the cable leading-out part. The jacking pulley moves on the track to jack up or release the cable, so that the length of the cable portion between the cable fixing part and the cable leading-out part is adjusted, and winding and unwinding are realized. Therefore, when the cable is not needed, the cable can be wound into the cable winding and unwinding device through the cable winding and unwinding device, the cable is prevented from being exposed, the hidden danger that the cable is damaged by external force is eliminated, the problem that the cable is inconvenient to store issolved, and the service life of the cable can be prolonged.

Description

technical field [0001] The invention relates to a cable retracting device. Background technique [0002] With the popularity of new energy electric vehicles, the market demand for high-current fast charging is becoming more and more urgent. However, the increase of the charging current will inevitably lead to the thickening of the charging gun wire, making it difficult to move during charging, especially when the gun wire is stored, which is extremely inconvenient. [0003] At present, most of the DC charging gun wires are exposed to the outside. They are dragged on the ground at will during charging, and are thrown on the ground after charging, making the gun wires vulnerable to various external stresses, such as people trampling on them, cars running over them, etc. Under such conditions of use Under normal circumstances, the gun wire will have problems such as damaged insulation, bulges, and aging after one year, which poses a greater safety hazard.
