Description

Technical Field

[0001] The utility model relates to the technical field of charging pile protection boxes, in particular to a wire synchronous operation protection structure for a charging pile protection box. Background Art

[0002] A charging pile is a device that provides power replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in parking lots of public buildings and residential communities. It can charge various types of electric vehicles according to the adjusted voltage and current. The wire synchronous operation protection structure is a structure that protects the cables in the charging pile. The setting of the protection structure can increase the service life of the cables inside the charging pile.

[0003] Prior art includes a utility model with publication number CN220009509U, which discloses a wire synchronous operation protection structure for a charging pile protection box. The patent adopts a mounting plate for mounting a charging pile control system; a movable box for mounting a charging gun electrically connected to the control system via a wire; a wire synchronous operation structure for supporting the wire, and the wire synchronous operation mechanism includes at least two wire supporting arms, one end of the two wire supporting arms is movably connected by a bolt, and the other end is movably mounted on the mounting plate and the movable box respectively. When the movable box is pulled down, the movable box drives the two wire supporting arms to rotate and unfold the folded wire; by providing a wire synchronous operation structure, the wire is protected by the wire supporting arms, and the folding and unfolding movement trajectory of the wire can be controlled at the same time, the movement is more orderly, wear is reduced, and scratches, entanglement and jamming are avoided, the service life of the wire is effectively increased, and user needs are met. The problem that the charging pile stretches and contracts the wire when it is raised and lowered is solved. Due to the lack of a structure to protect the wire, the wire will be severely worn after a period of time, and may also be entangled or hooked on other parts of the charging pile, causing jamming, resulting in unsatisfactory use effect.

Therefore, after long-term use, the rubber insulation layer on the cable surface will be damaged. Utility Model Content
