Reinforcement structure of rear upper inner panel of automobile side panel and vehicle

Abstract

The invention discloses a side panel rear upper inner panel and a reinforced structure and a vehicle, comprising a rear wheel bulge outer panel, a side panel rear lower inner panel reinforcement, a side panel rear upper inner panel, a middle section of a D-pillar outer panel, and a top cover Rear beam support plate reinforcement plate, rear wheel bulge inner plate, rear wheel bulge inner plate reinforcement, D-pillar inner panel middle section, roof rear beam support plate, side panel rear upper inner panel upper reinforcement and side panel rear upper inner panel Rear section; the inner plate of the rear wheel bulge is connected with the reinforcement of the inner plate of the rear wheel bulge and the outer plate of the rear wheel bulge to form the rear wheel bulge assembly; the rear beam support plate of the top cover, the reinforcement plate of the rear beam support plate of the top cover, and the inner plate of the D-pillar The middle section and the middle section of the D-pillar outer panel are connected to form a complete D-pillar cavity structure; the upper reinforcement of the side panel rear upper inner panel is connected to the D-pillar cavity structure; the side panel rear upper inner panel is respectively reinforced with the side panel rear upper inner panel upper part Parts, D-pillar cavity structure and rear wheel drum assembly. The invention can improve the torsional rigidity of the vehicle body and the rigidity of the rear upper inner panel of the side wall.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a reinforcement structure of a rear upper inner panel of a side wall of an automobile and a vehicle. Background technique [0002] With the development of automobile technology and the more and more abundant new technology configuration of automobiles, the requirements for car body-related performance are getting higher and higher. In the two-box models represented by SUVs, since there is no structure such as a storage panel, compared with sedans, the rear doors of SUVs are larger and heavier, so higher rigidity requirements are imposed on the rear area of ​​the side walls. Especially with the widespread application of electric back door technology, it is required that the electric back door can be opened and closed normally and automatically on special torsion roads, and the torsional rigidity of the body and the rigidity of the back door frame are required to be highe...

AI Technical Summary

Problems solved by technology

[0004] 1. Considering the cost and process forming, the rear upper inner panel 3 of the side wall is often made of thinner and lower-strength materials. Therefore, after welding with peripheral parts, the overall structure is weak, which is not conducive to the improvement of body rigidity;

[0005] 2. If figure 1 and figure 2 As shown, there is only one layer of thin plate structure in the top area of ​​the rear upper inner panel 3 of the side wall, and there is no reinforcement structure to connect the lower rear inner panel reinforcement 2 of the side wall with the reinforcement plate 5 of the rear cross member support plate of the top cover, and the structure of the reinforcement cavity is incoherent , the force transmission channel is not smooth; the rigidity of the top area of ​​the rear upper inner panel 3 of the side wall is weak, and it is not conducive to the improvement of the torsional rigidity of the vehicle body;

[0006] 3. If figure 1 and image 3 As shown, the rear upper inner panel 3 of the side wall has only one layer of thin plate structure in the rear area, and there is no reinforcement structure to connect the lower rear inner panel reinforcement 2 of the side wall with the middle section 4 of the outer panel of the D-pillar, and the structure of the reinforced cavity is incoherent. The force transmission channel is not smooth; the rigidity of the rear upper inner panel 1 area of ​​the side wall is weak, and the reinforcement support for the D-pillar cavity structure is insufficient, which is not conducive to the improvement of the torsional rigidity of the vehicle body; it may especially cause insufficient rigidity of the rear door frame of the vehicle body. The serious deformation of the back door frame of the car body under the road condition makes it impossible or difficult to close the back door;

[0007] 4. This structural design leads to the side rear upper inner panel 3 and the side rear lower inner panel reinforcement 2 parts are relatively irregular, and the material utilization rate is low
