Abstract

The invention relates to a frame-type car body rear compartment structure and a welding method. The structure comprises a first side assembly at the rear portion of a car body, a second side assemblyat the rear portion of the car body, a first cross beam assembly at the rear portion, a second cross beam assembly at the rear portion, a battery box frame fixing assisting beam, a storage battery cross beam and a process beam, wherein the process beam is mounted between the bottom of the first side assembly at the rear portion of the car body and the bottom of the second side assembly at the rearportion of the car body. According to the structure and the welding method, the welding quality of a rear compartment of the car body and a welding process for welding deformation can be effectivelycontrolled, the repair quantity and size adjustment of welding seams are reduced, the welding seam quality and structural size of the rear compartment of the car body are ensured, the production efficiency is improved, and the qualification rate of products is increased.

Description

technical field [0001] The invention relates to the technical field of automobile processing, in particular to a frame-type vehicle body rear compartment structure and a welding method. Background technique [0002] The world's automobile industry pays more and more attention to energy saving and environmental protection. Reducing the weight of automobiles to reduce energy consumption has become an important direction for major automobile companies to improve their competitiveness. Based on this, body weight reduction technology is gradually being used by the automobile industry, which is also one of the main weight reduction methods adopted by various automobile manufacturers. [0003] At present, the lightweight technology of the body is mainly reflected in the use of aluminum alloy materials with lighter weight, better corrosion resistance and better mechanical properties in large areas of the body. Through the optimization of body materials, the weight of the entire body...
