Vehicle body part maintenance method

Abstract

The invention discloses a vehicle body part maintenance method. The method comprises the following steps: a damage state including deformation damage and breakage damage of a damage area is judged; a dead angle deformation area with an included angle of smaller than 90 degrees is judged to form on the damage area of a vehicle body part; if the dead angle deformation area exists, the dead angle deformation area is firstly heated and locally shaped to eliminate the dead angle deformation area; if no dead angle deformation area is on the damage area, or the dead angle is eliminated, the damage area is heated and overally shaped, and the overall shape of the damage area is recovered to an initial shape; if the damage area is breakage damage, the spot welding is performed for the breakage place, then, a reinforcing net covers the breakage place of the damage area, and the reinforcing net is buried in the damage area through buried welding; if the damage state is deformation damage or the reinforcing net is buried, the damage area is heated and leveled to recover to an original plane and / or a curved surface; and the outer surface of the damage area is polished and painted.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a maintenance method for body parts. Background technique [0002] With the development of modern automobile design concepts, in order to reduce the weight of vehicles and strengthen the protection of pedestrians in traffic accidents, many exterior decorative parts of automobiles are made of plastic materials. Especially the front and rear bumper exterior trim panels (being commonly called as bumper skin) of automobile are usually made of plastic materials. When a motor vehicle collides, the external parts of the body can play a good buffer role. But correspondingly, these external accessories are also prone to physical deformation and damage. [0003] For the damage of such structural accessories, the traditional vehicle maintenance industry usually directly adopts the replacement method to complete the maintenance. Because the damage of structural accessories is...

AI Technical Summary

Problems solved by technology

First of all, waste structural parts are difficult to degrade, and recycling will cause environmental pollution due to smelting and recycling

Second, discarding structural accessories when the damage is not serious results in material waste

Third, the structural parts of the vehicle are often of high value, and the replacement of new structural parts will result in higher costs

However, the maintenance method of directly replacing structural parts has caused a serious waste of resources and costs.
