Abstract

The invention provides a C-column reinforcing plate connecting structure which is large enough in torsion rigidity and not likely to crack. The structure comprises a C-column reinforcing plate, the upper end of the C-column reinforcing plate extends to a boundary beam of a car body, the lower end of the C-column reinforcing plate is welded to the outer side of a back wheel cover outer plate, the back wheel cover outer plate and a back wheel cover inner plate are welded into a whole, a back wheel cover inner plate reinforcing plate is arranged at the inner side of the back wheel cover inner plate, the upper end of the back wheel cover inner plate reinforcing plate extends convexly to the upper portion of the back wheel cover inner plate to be welded to the back wheel cover outer plate, andthe C-column reinforcing plate and the back wheel cover inner plate reinforcing plate are welded into a whole. According to the scheme, the C-column reinforcing plate and the back wheel cover inner plate reinforcing plate are connected, a precise and effective force transfer path is formed between the C-column reinforcing plate and the back wheel cover inner plate, smooth stress transfer is ensured, local stress concentration is avoided, and energy is effectively absorbed. The whole transfer path forms a complete C ring, so that the torsional rigidity of the whole car body is improved, cracking of the car body is avoided, and jolting of the car body is lowered.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a connection structure of a C-pillar reinforcement plate. Background technique [0002] The C-pillar of the car is the third column that runs through the top cover and the lower body of the car's side wall. If the car's middle door is a revolving door, it plays an important role in carrying the middle door. At the same time, the torsional performance of the car's C-pillar on the body , the stiffness of the top cover, and the stiffness of the rear door lock pin installation point also play an important role, so a C-pillar reinforcement plate is usually installed on the C-pillar to improve the overall strength of the C-pillar. The connection structure of the C-pillar reinforcement plate is the key joint position of the body frame. Its structure directly affects the stiffness and mode of the frame body. Insufficient stiffness will easily lead to large local deformation of the body, stress ...
