Rear structure of inner plate for SUV (sports utility vehicle) vehicle model

Abstract

The invention relates to a rear structure of an inner plate for an SUV (sport utility vehicle) vehicle model. The rear structure comprises a C-column inner plate (1), an upper D-column inner plate (2), a lower D-column inner plate (3), a C-column reinforcing plate (4), an upper D-column reinforcing plate (6), a lower D-column reinforcing plate (7), a wheel casing inner plate assembly (9) and a wheel casing outer plate (10); the rear structure of the inner plate is characterized in that a connecting plate (5) is arranged between the C-column reinforcing plate (4) and the lower D-column reinforcing plate (7).

Description

technical field [0001] The invention relates to a rear structure of an inner panel of an SUV vehicle. Background technique [0002] In the prior art, the rear structure of the inner panel of the SUV model includes a C-pillar inner panel, a D-pillar upper inner panel, a D-pillar lower inner panel, a C-pillar reinforcement panel, a D-pillar upper reinforcement panel, a D-pillar lower reinforcement panel, and an inner panel of the wheel house. Plate assembly, wheel house outer plate, wheel house outer reinforcement plate. The connection method is that the lower end of the C-pillar reinforcement plate is connected with the wheel house outer panel and the wheel house outer reinforcement plate, and the upper end is connected with the front end of the upper side beam of the D-pillar reinforcement plate to form a C-pillar reinforcement structure; the upper reinforcement plate of the D-pillar is connected with the D-pillar reinforcement plate The reinforcement plates under the colum...

AI Technical Summary

Problems solved by technology

[0003] 1. The reinforced structure of the C-pillar and the reinforced structure of the D-pillar are only connected at the upper end, and the overall connection is not effective, which is not conducive to the transmission of force;

[0004] 2. The inside and outside of the C-pillar reinforcement plate cannot form an effective ring-shaped cross-sectional structure, which is not conducive to the stiffness mode of the body;

[0005] 3. The outer reinforcement plate of the wheel house cannot be closed-loop with other structural forms, resulting in an increase in the weight of the vehicle body, which does not significantly improve the performance of the vehicle body, and is not conducive to lightweight design;

[0006] 4. The D-pillar upper inner panel, the D-pillar upper reinforcement panel and the C-pillar inner panel are not effectively connected, which affects the performance of the upper joint of the D-pillar closed loop
