Vehicle body side wall C-column inner plate reinforced structure and vehicle

Abstract

The invention discloses a vehicle body side wall C-column inner plate reinforced structure, and relates to the technical field of vehicle structure design. The vehicle body side wall C-column inner plate reinforced structure includes a rear wheel cover outer plate, a C-column front segment inner plate body, a C-column rear segment inner plate body, a C-column top cover rear beam connecting plate,a C-column rear segment reinforced upper plate, a C-column rear segment reinforced lower plate, and a C-column front segment reinforced plate body, wherein the C-column rear segment reinforced upper plate and the C-column rear segment reinforced lower plate are lap-jointed on the outer sides of the C-column top cover rear beam connecting plate and the C-column rear segment inner plate body to forma first cavity structure of a tail door frame structure; and the periphery of the C-column front segment reinforced plate body is lap-jointed on the outer sides of the rear wheel cover outer plate, the C-column front segment inner plate body, the C-column front segment inner plate body and the tail door frame structure to form a second cavity structure communicating with the first cavity structure. According to the vehicle body side wall C-column inner plate reinforced structure, the C-column front segment reinforced plate body is arranged to be of an integrated structure, and integral rigidity of a C-column upper reinforced zone and torsional rigidity of the door frame structure are improved.

Description

Technical field [0001] The invention relates to the technical field of vehicle structure design, and in particular to a reinforced structure of a C-pillar inner panel of a vehicle body side wall and a vehicle. Background technique [0002] The body-in-white stiffness is one of the important indicators of the body structure performance. The main purpose is to reduce the performance problems of noise, vibration and harshness caused by insufficient body stiffness. This requires the body structure design to increase the body stiffness, the higher the stiffness , The smaller the noise, the smaller the probability of causing abnormal noise. In the body structure design section, the design of the rear of the body is particularly important. The rigidity of the rear is insufficient and the torsional rigidity of the body is insufficient. The design of the C-pillar reinforcement plate is an important part of the rear design, which is of great significance for improving the torsional rigidi...
