Self-winding device for charging pile

Abstract

The invention discloses a self-winding device for a charging pile, and relates to the technical field of charging piles. The self-winding device comprises a cabinet, two cables are electrically connected with an inner circuit board of the cabinet, the cables penetrate through the side surface of the cabinet and are electrically connected with a charging gun, a winding device is mounted on the inner wall of the side surface of the cabinet, a cable box is mounted on the inner wall of the bottom surface of the cabinet, the cable box is located below the winding device, and the winding device comprises a connecting shaft, a driving sleeve, a sliding sleeve and a rotating sleeve. According to the self-winding device, the driving sleeve is driven to rotate through a driving mechanism, and the sliding sleeve is driven by a sliding mechanism to slide on the circumferential side face of the driving sleeve, according to the different displacement amounts of the sliding sleeve, so that a clampingblock is in clamped connection with a first clamping groove or second clamping groove, or the first clamping groove and a second annular groove in the rotating sleeve, finally, the fact that one or two rotating sleeves drive the cables to conduct the single-way rotating winding is achieved, automatic single-way winding of the cables can be achieved through the process, the wear of the cables is avoided, and the service life of the charging pile is prolonged.

Description

technical field [0001] The invention belongs to the technical field of charging piles, in particular to a self-winding device for charging piles. Background technique [0002] Electric vehicles have always been regarded as the development trend of the next generation of vehicles. As a "gas station" for electric vehicles, the full development of charging pile construction will undoubtedly provide a huge market. In the three major cities of Beijing, Shanghai and Guangzhou, due to traffic congestion, restrictions on car purchases have been imposed through license plates. [0003] With the popularization of electric vehicles, some existing parking lots will be equipped with charging piles. In order to save resources, most of the charging piles will be equipped with two charging guns; and the cables connected to the charging guns are usually placed in the car after being used by the car owner. The ground, but it is inevitable that there will be water and corrosive substances on...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-winding device for charging piles, which drives the transmission sleeve to rotate through the transmission mechanism, so that the transmission sleeve drives the sliding sleeve to rotate; and the sliding mechanism drives the sliding sleeve to rotate on the side of the transmission sleeve. Sliding up; according to the displacement of the sliding sleeve, the block on the sliding sleeve engages with the first slot or the second annular slot on a rotating sleeve or with the first slots on two rotating sleeves It is snapped together with the second annular groove at the same time, and finally realizes one or two rotating sleeves to drive the cable to rotate and wind in one direction, which solves the problem that the existing charging gun cable cannot be wound and collected, resulting in cable wear and reduced service life of the charging pile.
