"And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0037] The body structure is the main load-bearing structure of the vehicle, which is used to install vehicle parts. It may include the part of the body structure located between the vehicle wheel hub and the trunk. On the one hand, the body structure located here is used to install the vehicle wheel hub; on the other hand, the body structure located here is used to install the hinge structure to match the trunk door. Therefore, the body structure located here has higher requirements for structural strength.

[0038] In order to solve the above technical problems, refer to Figures 1 to 3 As shown, the present application provides a vehicle body structure, including a wheel arch plate assembly 10 and a mounting plate assembly 20, the wheel arch plate assembly 10 forms a wheel hub cavity 11, and the side wall of the wheel hub cavity 11 forms a mounting area 12; the mounting plate assembly 20 includes a mounting plate 21, a reinforcing plate 22 and a supporting plate 23, the mounting plate 21 and the reinforcing plate 22 are stacked in sequence from close to the wheel hub cavity 11 to away from the wheel hub cavity 11, the mounting plate 21 and the reinforcing plate 22 are arranged in the mounting area 12 and are arranged at an angle to the wheel arch plate assembly 10, the mounting plate 21 and the reinforcing plate 22 are formed with mounting holes 2101, one side of the supporting plate 23 extends toward a side away from the wheel hub cavity 11 and is connected to the wheel arch plate assembly 10, and at least one flange 24 is formed on the other side of the supporting plate 23, and the flange 24 is welded to at least the reinforcing plate 22 to support the mounting plate 21 and the reinforcing plate 22 located in the mounting area 12.

[0039] By forming a plate stacking structure of at least three layers including a mounting plate 21, a reinforcing plate 22 and a supporting plate 23, the thickness of the mounting plate assembly 20 is increased, and one side of the supporting plate 23 is extended to the side away from the wheel hub cavity 11 and connected to the wheel cover plate assembly 10, and at least one flange 24 is formed on the other side of the supporting plate 23 to form support between the wheel cover plate assembly 10 and the mounting plate assembly 20 through the supporting plate 23. When subjected to force, the supporting plate 23 can further provide supporting force and pulling force for the mounting plate 21 and the reinforcing plate 22 to reduce the risk of the mounting plate 21 and the reinforcing plate 22 collapsing to one side; the flange 24 is at least welded to the reinforcing plate 22 to ensure the connection strength between the supporting plate 23, the reinforcing plate 22 and / or the mounting plate 21; thus, the structural strength of the mounting plate assembly 20 can be increased through the above design.

[0040] In some embodiments, the wheel arch plate assembly 10 and the mounting plate assembly 20 can be formed by a stamping process. Through the above design, the structural strength of the vehicle body structure here can be greatly improved. Experimental verification shows that the structural strength of the vehicle body structure can be increased from 1031N / mm to 1282N / mm. In addition, through the welding process, the dimensional deviation of the vehicle body structure in the vertical direction can be absorbed by the welding tooling, so as to improve the matching accuracy of the vehicle body structure.

[0041] In some embodiments, reference Figure 1 and Figure 2 As shown, the wheel housing plate assembly 10 includes a wheel housing inner plate 13 and a wheel housing outer plate 14, which cooperate with each other to form a wheel hub cavity 11, wherein the wheel housing inner plate 13 and the wheel housing outer plate 14 can be connected by welding, riveting and other processes. The outer plate of the wheel hub cavity 11 is downward in the vertical direction, and the side away from the roller cavity outer plate is the vehicle load-bearing column, which can be a B-pillar, a C-pillar, etc., and the present application is a C-pillar. The body structure at the height of the C-pillar forms an opening of the trunk, so it is necessary to set a hinge on the wheel housing plate assembly 10 to cooperate with the trunk door to open and close.

A hinge mounting hole 2101 can be formed on the first step surface 31 for installing the hinge, and the second step surface 32 can be used to connect the mounting plate assembly 20 and the wheel cover plate assembly 10. The formed first flange 241, second flange 242 and third flange 243 can be welded to the first step surface 31 and the second step surface 32 respectively to increase the welding area of ​​the flange 24, thereby increasing the connection strength between the support member and the reinforcing plate 22 and the mounting plate 21.

Thus, different parts of the reinforcing plate 22 and the mounting plate 21 are welded respectively by the first welding portion 41, the second welding portion 42 and the third welding portion 43, so as to reduce the number of welding positions, thereby saving the process flow and ensuring the structural strength of the mounting plate assembly 20.
