Protective device and protective method for vehicle frame grounding

Abstract

The invention discloses a grounding protection device and a protection method for a vehicle frame, which is characterized in that it includes a mounting hole arranged at the position of the grounding point on the vehicle frame, and a bolt is inserted in the mounting hole during electrophoresis, and the A cap nut covering the protruding end is connected to the protruding end, and a flat washer placed between the cap nut and the vehicle frame is arranged on the bolt. The vehicle frame ground iron protection device and protection method of the present invention have simple structure and simple operation, can not damage the matrix material, and at the same time help to realize the conductive function of the ground iron point, and have strong practicability and good application prospects.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a vehicle frame grounding protection device and a protection method. Background technique [0002] The car forms the current loop of the whole vehicle through the grounding point. For a car with a frame, the grounding point of the chassis circuit is usually set on the frame. The frame needs electrophoretic paint to meet the surface protection requirements. Generally, the conductivity of electrophoretic paint cannot meet the requirements. Protect the ground point to avoid the immersion of electrophoretic paint; similar technologies usually remove the paint film on the ground point or weld the ground parts to the substrate to meet the conductive requirements. This method not only increases the cost but also affects the frame. Substrate damage. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior...
