Pre-adjusting method of new energy automobile charging pile wire automatic winding device

Abstract

The invention discloses a pre-adjusting method of a new energy automobile charging pile wire automatic winding device. The new energy automobile charging pile wire automatic winding device comprises awire winding outer barrel for spirally winding or unwinding a charging wire, an automatic wiring device for limiting the charging wire to be distributed on the winding outer barrel along a spiral track, an automatic wire clamping device for clamping and fixing the charging wire wound on the wire winding outer barrel, and a pre-adjusting device. The pre-adjusting method comprises the steps that: the part, exposed out of the upper portion of a machine head shell body, of a driving screw is rotated; the driving screw rotates to drive a square nut to move along a direction longitudinal hole; themovement of the square nut causes the compression amount of a range adjusting pressure spring in a normal state; and an elastic force of the range adjusting pressure spring applied to a range adjusting longitudinal rod and extrusion stress of the range adjusting longitudinal rod applied to the right side of the inclined end surface are adjusted, the tight contact between an adjusting disc and theleft end of a swing block assembly is ensured, and certain pressing force and friction force are kept.

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
