Standardized automobile body-in-white welding assembly structure

Abstract

The invention discloses a standardized automobile body-in-white welding assembly structure. The structure comprises a roof outside plate assembly module (1), a roof rear beam assembly module (2), a roof front beam assembly module (3), a left-side panel assembly module (4), a right-side panel assembly module (5) and an automobile body bottom assemble module (6). The structure is characterized in that the roof outside plate assembly module (1), the roof rear beam assembly module (2), the roof front beam assembly module (3), the left-side enclosurepanel assembly module (4), the right-side panel assembly module (5) and the automobile body bottom assemble module (6) are combined together in a screw joint manner or a rivet joint manner to constitute the standardized automobile body-in-white welding assembly structure. By the aid of the standardized automobile body-in-white welding assembly structure, design cycle can be effectively lowered, design cost is saved, mould designing and manufacturing cost can be reduced to the greatest extent, and a production line is almost not needed to be adjusted.

Description

technical field [0001] The invention belongs to the technical field of automobile engineering, in particular to a novel standardized automobile body-in-white welding assembly structure. Background technique [0002] The traditional car body structure includes the engine compartment, front wall, roof, floor, side wall inner and outer panels, rear wall, longitudinal beams, cross beams and reinforcement plates. Based on this traditional structure: [0003] In the process of developing a new model, it is necessary to redesign the inner panel structure and redevelop the body-in-white mold. The basic development cycle reaches 36 months, which will definitely delay the launch of the new model; [0004] In the development process of new models, due to the change of appearance, the structural characteristics of the body-in-white will inevitably change, so the body-in-white mold needs to be redeveloped, which greatly increases the manufacturing cost, and also causes a huge waste of th...
