Abstract

The invention relates to a side body rear supporting column inner plate dividing structure, and belongs to the technical field of a side body of a passenger car. The side body rear supporting column inner plate dividing structure comprises a rear supporting column inner plate, wherein the rear supporting column inner plate is divided into a rear supporting column inner plate body and a rear supporting column inner plate angle plate, and the rear supporting column inner plate body is provided with a reinforcing plate. The side body rear supporting column inner plate dividing structure is simple and reasonable, the process is easy to carry out, the portion, almost parallel with a back door seam allowance, of the rear supporting column inner plate is divided into two pieces, the two pieces are made of different materials, and accordingly punching forming performance of the rear supporting column inner plate is guaranteed, rigidity of the periphery of a rear back door can be improved, and torsional rigidity of a vehicle body is improved. Meanwhile, the inner side of the rear supporting column inner plate is provided with the reinforcing plate, and the connection strength of the front portion and the rear portion of the rear supporting column inner plate is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of side walls of passenger cars, and in particular relates to a block structure of a rear pillar inner panel of a side wall. Background technique [0002] The inner plate of the rear pillar is located in the rear half of the side wall, the inner side of the side wall assembly. The inner plate of the rear pillar is often a large and complicated part with a large drawing depth and a negative stamping angle, which makes it difficult to achieve overall stamping Forming is prone to cracking in the stamping process. Therefore, it is very beneficial to design a block structure that can not only ensure that the process is feasible, but also save mold costs and welding costs, and achieve higher manufacturing accuracy. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a block structure of the inner panel of the rear pillar of the side wall. [0004] ...
