Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In this disclosure, unless stated otherwise, the used orientation words such as "up, down, front, and rear" are usually relative to the state of the vehicle's normal driving, and specifically, "upward" refers to the normal driving state of the vehicle. When facing the roof direction of the vehicle, down refers to the direction towards the floor of the vehicle when the vehicle is running normally, forward refers to the forward direction of the vehicle when the vehicle is running normally, and rear refers to the direction away from the vehicle when the vehicle is running normally. "Inner and outer" are relative to the central cross-section in the longitu...

Abstract

The invention relates to a vehicle body side wall structure, a C pillar reinforcing plate and a vehicle. The vehicle body side wall structure comprises a C pillar inner plate, a wheel cover outer plate fixed to the lower edge of the C pillar inner plate and the C pillar reinforcing plate fixed to the C pillar inner plate and the wheel cover outer plate. The upper end of the C pillar reinforcing plate is connected to a connector of the vehicle body side wall structure, the lower end of the C pillar reinforcing plate is connected to the wheel cover outer plate, and the C pillar inner plate, the wheel cover outer plate and the C pillar reinforcing plate jointly define a cavity structure. By fixing the C pillar reinforcing plate between the C pillar inner plate and the wheel cover outer plate, and by arranging the cavity structure extending from the connector to the wheel cover outer plate on the vehicle body side wall structure, the overall rigidity and the strength of the CD pillar are improved greatly, and the modality and the torsional rigidity of the vehicle are improved. In addition, the C pillar reinforcing plate is connected between the connector of the vehicle body side wall structure and the wheel cover outer plate, a force transmission path of a vehicle body framework is increased, the phenomenon that impact force concentration happens on the vehicle body framework is avoided, and prolonging of the service life of the vehicle body framework is facilitated.

Description

technical field [0001] The present disclosure relates to the field of body-in-white parts, in particular, to a body side wall structure, a C-pillar reinforcement plate and a vehicle. Background technique [0002] In the rear CD-pillar structure of the existing body side wall, the D-pillar structure is formed by welding the rear section of the upper reinforcing plate of the side wall, the upper reinforcing plate of the D-pillar, the lower reinforcing plate of the D-pillar and the middle plate of the D-pillar, and then the inner plate of the C-pillar, The wheel house outer panel and the lower panel of the C-pillar inner panel are welded into the C-pillar structure, and then the overall D-pillar structure and C-pillar structure are welded into the CD-pillar structure of the vehicle body. Finally, the C-pillar lock hook nut plate fixing brackets are welded to the wheel house outer panel and the lower panel of the C-pillar inner panel respectively to form a complete CD-pillar str...
