A pre-adjustment method for a new energy vehicle charging pile electric wire automatic winding device

Abstract

This application discloses an automatic rewinding device for charging pile wires of new energy vehicles, which includes: an outer cylinder for winding or releasing the charging wire in a spiral shape, and an automatic device for restricting the distribution of the charging wire along the spiral trajectory on the outer cylinder for reeling. The wiring device, the automatic wire clamping device that clamps and fixes the charging wire that has been wound on the outer cylinder of the reel, and also includes a pre-adjustment device; the pre-adjustment method includes the following steps: rotating the active screw to be exposed above the machine head housing part; the active screw rod rotates to drive the square nut to move along the square longitudinal hole; the movement of the square nut adjusts the compression amount of the adjustment pressure spring under normal conditions; and then adjusts the adjustment pressure spring to the adjustment longitudinal rod The elastic force of the adjustment longitudinal rod and the pressing stress on the inclined end face to the right ensure that the adjustment disc and the left end of the pendulum block assembly are in close contact and maintain a certain pressing force and friction.

Description

technical field [0001] The present application relates to the technical field of new energy vehicle charging piles, in particular to a pre-adjustment method for an automatic winding device for electric wires of new energy vehicle charging piles. Background technique [0002] With the gradual exhaustion of fossil fuels, the demand for new energy in human society is becoming stronger and stronger. As for the cars that are needed for daily travel, there is also an urgent need for replacement. The development of new energy vehicles in my country is in full swing. At present, the two most popular types of new energy vehicles on the market are: [0003] The first type, Blade Electric Vehicles (BEV), is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to drive the motor to run Push the car to go. [0004] The second category, hybrid electr...

Problems solved by technology

[0006] The exposed distance of the charging line is certain. For some large cars or new energy vehicles whose charging port is far away from the charging pile, the exposed charging line is not enough to support the charging port. As far as new energy vehicles are concerned, after the charging gun is inserted into the car charging port, there is still a long distance charging cable hanging outside the charging pile, and the swinging charging cable is easy to hang on pedestrians or passing vehicles, causing accidents
