[0047] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] Embodiment 1

[0049] This embodiment relates to a rear wheel housing inner panel assembly, which comprises a rear wheel housing inner panel 1, a mounting frame 2, and a rear shock absorber support 4 and a shock absorber support plate 3 arranged on the side of the rear wheel housing inner panel 1 facing the outside of the vehicle. In the front-to-back direction of the vehicle, the front end of the mounting frame 2 is connected to the rear wheel housing inner panel 1, the rear end of the mounting frame 2 extends backward and is connected to the D-pillar, and a vehicle-mounted electrical device mounting point is arranged on the mounting frame 2. A cavity 5 is formed between the rear shock absorber support 4 and the rear wheel housing inner panel 1, and the rear shock absorber support plate 3 is arranged in the cavity 5 and connected between the rear wheel housing inner panel 1 and the rear shock absorber support 4.

[0050] It is understandable that by providing a mounting frame 2 for mounting electrical components on the rear wheel housing inner plate 1, it is possible to provide a mounting space for the electrical components on the vehicle, thereby facilitating the arrangement of the electrical components on the vehicle body. Furthermore, by forming a cavity 5 between the rear shock absorber support 4 and the rear wheel housing inner plate 1, and connecting the rear shock absorber support plate 3 between the rear wheel housing inner plate 1 and the rear shock absorber support 4, it is possible to support the rear shock absorber support 4, thereby ensuring the installation strength of the rear shock absorber and also facilitating the improvement of the strength of the rear wheel housing inner plate 1, thereby utilizing the structural strength of the rear wheel housing inner plate 1 to improve the installation stability of the mounting frame 2 and the electrical components.

[0051] It should be noted that the vehicle-mounted electrical component mounting points disposed on the mounting frame 2 may be structures commonly used in the prior art for mounting electrical components, such as mounting holes, mounting grooves, etc. disposed on the mounting frame 2 .

[0052] Based on the above overall introduction, an exemplary structure of this embodiment is as follows Figures 1 to 10 And, as a preferred implementation, as Figure 4 and Figure 6 and Fig.10 As shown in the figure, in this embodiment, the shock absorber support plate 3 has a protruding portion 301 protruding toward the rear shock absorber support 4. A first sub-cavity 6 is formed between the protruding portion 301 and the rear wheel housing inner plate 1 and the mounting frame 2, and the first sub-cavity 6 extends to the top of the rear wheel housing inner plate 1 along the vertical direction of the vehicle.

[0053] It can be understood that by forming a first sub-cavity 6 between the protruding portion 301 and the rear wheel cover inner panel 1 and the mounting frame 2, and extending the first sub-cavity 6 to the top of the rear wheel cover inner panel 1, the high strength of the cavity structure can be utilized to improve the structural strength of the top of the rear wheel cover inner panel 1, and the mounting frame 2 can be supported to improve the structural strength of the connection position between the mounting frame 2 and the rear wheel cover inner panel 1, thereby improving the installation stability of electrical components.

[0054] Of course, the above-mentioned formation of the first sub-cavity 6 between the protruding portion 301 and the rear wheel housing inner panel 1 and the mounting frame 2 is determined according to the structure of the rear wheel housing inner panel 1 and the mounting frame 2. In addition, when the structure of the rear wheel housing inner panel 1 and the mounting frame 2 is changed, the first sub-cavity 6 can also be formed only between the protruding portion 301 and the rear wheel housing inner panel 1, or between the protruding portion 301 and the mounting frame 2.

[0055] As a preferred implementation method, Figure 2 and Figure 3 and Figure 8 As shown in the figure, the rear wheel housing inner panel assembly of this embodiment further includes a support reinforcement plate 7, which is connected between the rear shock absorber support 4 and the rear wheel housing inner panel 1. The support reinforcement plate 7 has a bulging portion 701 bulging toward the rear wheel housing inner panel 1, and a second sub-cavity 8 is formed between the bulging portion 701 and the rear shock absorber support 4. Such an arrangement facilitates the use of the high strength of the cavity structure to improve the overall rigidity of the rear shock absorber mounting point, thereby ensuring the reliability of the rear shock absorber installation.

[0056] And preferably, combined with Figure 5 and Figure 6 As shown in , in this embodiment, the second sub-cavity 8 is located below the first sub-cavity 6, and the second sub-cavity 8 partially overlaps with the first sub-cavity 6 in the left-right direction of the whole vehicle. It should be noted that the above-mentioned second sub-cavity 8 partially overlaps with the first sub-cavity 6 in the left-right direction of the whole vehicle, specifically, it means that there is an overlapping area between the projections of the first sub-cavity 6 and the second sub-cavity 8 in the left-right direction of the whole vehicle.

[0057] By arranging the second sub-cavity 8 below the first sub-cavity 6 and making the first sub-cavity 6 partially overlap with the second sub-cavity 8 in the left-right direction of the vehicle, it is beneficial to improve the structural strength of the rear shock absorber support 4, while also being able to improve the structural strength of the rear wheel cover inner panel assembly in the up-and-down direction of the vehicle, meeting the corresponding performance index requirements, and thereby improving the stability of the mounting frame and electrical components.

[0058] As a preferred implementation method, Figure 7 and Figure 8 As shown in , the bending part of the bulging part 701 is provided with a reinforcing rib 7011, and the edge of the support reinforcing plate 7 is provided with a first flange 702 folded outwardly of the second sub-cavity 8, and the support reinforcing plate 7 is connected to the rear shock absorber support 4 through the first flange 702. It can be understood that by providing the reinforcing rib 7011 at the bending part of the bulging part 701, it is beneficial to improve the structural strength of the bulging part 701, thereby improving the structural strength of the support reinforcing plate 7, and ensuring the installation firmness of the rear shock absorber. In addition, by providing the first flange 702 at the edge of the support reinforcing plate 7, it is convenient to increase the connection area between the support reinforcing plate 7 and the rear shock absorber support 4, thereby ensuring the connection strength between the support reinforcing plate 7 and the rear shock absorber support 4.

[0059] Of course, in this embodiment, both the reinforcing rib 7011 is provided at the bending portion of the bulging portion 701, and the first flange 702 folded outwardly toward the second sub-cavity 8 is provided at the edge of the support reinforcing plate 7. This is only a preferred implementation method. In addition, it is also possible to choose to provide the reinforcing rib 7011 only at the bending portion of the bulging portion 701 without providing the first flange 702, or to provide the first flange 702 folded outwardly toward the second sub-cavity 8 only at the edge of the support reinforcing plate 7 without providing the reinforcing rib 7011.

[0060] As a preferred embodiment, Figure 7 and Fig. 9 As shown in , the rear wheel housing inner plate assembly of this embodiment also includes a reinforcing plate 9 connected to the support reinforcing plate 7. The reinforcing plate 9 is bent and formed with a groove 901, and the bulge 701 is arranged in the groove 901. By providing the reinforcing plate 9, the support reinforcing plate 7 can be structurally reinforced, thereby further improving the structural rigidity of the rear shock absorber installation position. In addition, the reinforcing plate 9 forms a groove 901, and the bulge 701 is located in the groove 901, which facilitates the arrangement of the reinforcing plate 9 and ensures the reinforcing effect of the reinforcing plate 9.

[0061] By providing the reinforcing plate 9, the strength requirement of the rear shock absorber mounting point can be met by increasing the material thickness of the reinforcing plate 9, so that the material thickness of the rear shock absorber support 4 and the support reinforcement plate 7 can be reduced accordingly, which is beneficial to weight reduction of the vehicle body while meeting the strength requirement.

[0062] As a preferred implementation, in this embodiment, the reinforcing plate 9 is connected to the side of the support reinforcement plate 7 facing the rear wheel housing inner plate 1, and the reinforcing plate 9 and the support reinforcement plate 7 are simultaneously connected to the shock absorber support plate 3. It can be understood that by making the reinforcing plate 9 and the support reinforcement plate 7 simultaneously connected to the shock absorber support plate 3, it is convenient for the shock absorber support plate 3 to play a better supporting role on the rear shock absorber mounting point, thereby ensuring the structural rigidity of the rear shock absorber mounting position. In addition, the force at the rear shock absorber mounting point can be transmitted to the shock absorber support plate 3 through the reinforcing plate 9 and the support reinforcement plate 7, which is conducive to improving the force transmission effect.

[0063] In addition, if Figure 1 and Fig.10 As shown in , the mounting frame 2 of this embodiment is a flat plate-like structure extending in the front-rear direction of the vehicle. A notch 10 is formed at the top of the rear wheel housing inner plate 1, the front end of the mounting frame 2 blocks the notch 10, and the top of the rear shock absorber support 4 is connected to the mounting frame 2. Such an arrangement is conducive to reducing the weight of the rear wheel housing inner plate assembly, and can make the mounting frame 2 and the rear wheel housing inner plate 1 have a larger connection area, which is conducive to ensuring the connection strength between the mounting frame 2 and the rear wheel housing inner plate 1, and at the same time, it can also improve the installation stability of the mounting frame 2 and the electrical components by virtue of the structural strength of the rear shock absorber installation position. At this time, the above-mentioned first sub-cavity 6 is formed between the rear shock absorber support plate 3, the mounting frame 2 and the rear wheel housing inner plate 1.

[0064] Of course, the above-mentioned formation of the notch 10 at the top of the rear wheel housing inner panel 1 and the blocking of the notch 10 by the front end of the mounting frame 2 is only a preferred embodiment. In addition, the notch 10 may not be provided at the top of the rear wheel housing inner panel 1. In this case, the front end of the mounting frame 2 may be connected to the top or rear end of the rear wheel housing inner panel 1. In this case, the first sub-cavity 6 may be formed between the rear shock absorber support and the rear wheel housing inner panel 1.

[0065] Preferably, in this embodiment, a reinforcing protrusion 101 is provided on the rear wheel housing inner plate 1, and a second flange 201 folded upward is provided on the edge of the mounting frame 2. Fig.10 As shown in the figure, a reinforcing protrusion 101 is provided at the front end of the rear wheel housing inner panel 1 to enhance the structural strength of the front end of the rear wheel housing inner panel 1. In addition, a second flange 201 is provided on the side of the mounting frame 2 facing the outside of the vehicle, which can enhance the structural strength of the mounting frame 2 and make the top of the side of the rear wheel housing inner panel assembly facing the outside of the vehicle flat and beautiful.

[0066] In addition, in the specific implementation, in order to facilitate the installation of the rear shock absorber, a rear shock absorber mounting hole 11 for mounting the rear shock absorber is provided on the rear shock absorber support 4, and the rear shock absorber mounting hole 11 is provided through the support reinforcement plate 7 and the reinforcement plate 9. Moreover, a front reinforcement part 401 and a rear reinforcement part 402 arched toward the outside of the vehicle are provided below the rear shock absorber support 4, and the front reinforcement part 401 and the rear reinforcement part 402 are arranged at intervals along the front and rear direction of the whole vehicle, and a cavity is formed between the front reinforcement part 401 and the rear reinforcement part 402 and the rear wheel housing inner plate 1.

[0067] It should also be noted that, in this embodiment, all components can be connected by welding methods such as spot welding. In addition, in order to ensure the connection effect, a first through hole 12 can be provided on the rear shock absorber support 4 at a position corresponding to the shock absorber support plate 3, so as to facilitate welding of the rear shock absorber support 4 and the shock absorber support plate 3 at the position of the first through hole 12. In addition, a second through hole 13 can be provided on the support reinforcement plate 7 at a position corresponding to the shock absorber support plate 3, and the second through hole 13 is provided through the reinforcement plate 9, so as to facilitate welding of the support reinforcement plate 7, the reinforcement plate 9 and the shock absorber support plate 3 through the second through hole 13.

[0068] The rear wheel housing inner panel assembly of this embodiment is provided with a mounting frame 2, and a vehicle-mounted electrical device mounting point is provided on the mounting frame 2, so as to provide an installation space for electrical devices, thereby facilitating the arrangement of electrical devices on the vehicle body. In addition, by providing a shock absorber support plate 3 and a support reinforcement plate 7, a first sub-cavity 6 is formed between the shock absorber support plate 3, the rear wheel housing inner panel 1 and the mounting frame 2, a second sub-cavity 8 is formed between the support reinforcement plate 7 and the rear shock absorber support 4, and the first sub-cavity 6 and the second sub-cavity 8 are partially overlapped in the left-right direction of the whole vehicle, which is conducive to ensuring the rigidity of the rear shock absorber installation position, and can improve the structural strength of the rear wheel housing inner panel assembly, and then the structural strength of the rear wheel housing inner panel assembly can be used to improve the installation stability of the mounting frame 2 and the electrical devices.
