[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0038] As shown in Figures 1 to 4 The embodiments of the present application provide a rear wheel housing 100, which is used for a vehicle.

[0039] The rear wheel housing 100 is provided with a first recess 110, a second recess 120 and a reinforcing structure 130. The rear wheel housing 100 is a cover-shaped structure with an opening, used for accommodating a wheel, Figure 1 The outer surface of the rear wheel housing 100, that is, the side surface away from the wheel, Figure 3 The inner surface of the rear wheel housing 100, that is, the side surface facing the wheel, the first recess 110 and the second recess 120 can be recesses formed by stamping. The first recess 110 and the second recess 120 also have openings, and the openings of the first recess 110 and the second recess 120 can be oriented in the same direction as the opening of the rear wheel housing 100.

[0040] The first recess 110 is used for connecting a C-pillar, the second recess 120 is used for connecting a D-pillar, and the reinforcing structure 130 is located between the first recess 110 and the second recess 120, and the two ends are connected with the first recess 110 and the second recess 120, respectively.

[0041] In an alternative embodiment, as Figure 1 and Figure 2As shown, the reinforcing structure 130 may include a third recess, which may be formed by stamping. The opening direction of the third recess may be the same as the opening direction of the rear wheel arch 100, that is, the recess direction of the third recess is consistent with the recess direction of the first recess 110 and the second recess 120. Of course, the opening direction of the third recess may also be opposite to the opening direction of the rear wheel arch 100, that is, the recess direction of the third recess is opposite to the recess direction of the first recess 110 and the second recess 120.

[0042] It should be noted that, in order to more clearly show the positional relationship of the outlines of the first recess 110, the second recess 120, and the third recess, Figure 2 The outline of each recess is marked by a thicker dashed line; the thicker dashed line is not the physical outline of the structure itself, but a schematic line added on the basis of the actual outline of the structure to highlight and clarify the spatial distribution and relative positional relationship of the first recess 110, the second recess 120 and the third recess.

[0043] In other alternative embodiments, the reinforcing structure 130 may also be a rib-like structure similar to the first reinforcing rib 150, wherein the rib-like structure is disposed laterally (i.e., along the direction from the first recess 110 to the second recess 120) in the region between the first recess 110 and the second recess 120, and the two ends of the rib-like structure are respectively connected to the first recess 110 and the second recess 120; or, the reinforcing structure 130 may also include a reinforcing plate and reinforcing ribs disposed on the reinforcing plate, wherein the two ends of the reinforcing plate are respectively connected to the first recess 110 and the second recess 120.

[0044] Providing a first recess 110 and a second recess 120 on the rear wheel arch 100 can improve the structural strength and torsional stiffness of the rear wheel arch 100.

[0045] The reinforcement structure 130 on the rear wheel arch 100 can further improve the structural strength of the rear wheel arch 100. The first recess 110 and the second recess 120 are connected by the reinforcement structure 130 to form a cross force transmission structure (such as "H" shape or "I" shape). This structure can more effectively resist torsional moment, so that the rear wheel arch 100 can better maintain structural stability when subjected to torsional force, reduce the deformation range, and thus improve the torsional stiffness of the rear wheel arch 100.

[0046] For example, after connecting the C-pillar and D-pillar to the rear floor frame, without the reinforcement structure 130, the first recess 110 and the second recess 120 are independent of each other. The force between them needs to be indirectly transmitted through the rear wheel arch body. Since the rear wheel arch body is usually a thin plate structure, when the C-pillar is under force, the force is transmitted from the C-pillar to the first recess 110, the rear wheel arch body, the second recess 120, and finally to the D-pillar. Since there is no direct connection structure between the first recess 110 and the second recess 120, the force between the first recess 110 and the second recess 120 needs to be transmitted through the rear wheel arch body. However, the rear wheel arch body is a thin sheet metal plate, which is more prone to local bending or shear deformation. Especially when subjected to torsional torque, the force transmission efficiency is low and torsional deformation is more likely to occur.

[0047] After the first recess 110 and the second recess 120 are connected by the reinforcing structure 130, the force between the first recess 110 and the second recess 120 can be transmitted through the reinforcing structure 130. For example, when the C-pillar is under stress, the force can be transmitted from the C-pillar to the first recess 110, the reinforcing structure 130, the second recess 120 and finally to the D-pillar. This force transmission method helps to alleviate the problem of excessive stress at a single point, reduces the generation of local high stress areas, and makes the stress distribution more uniform, thereby effectively improving the deformation of the rear wheel arch 100 under stress and further improving the torsional stiffness of the rear wheel arch 100.

[0048] In this embodiment, adding a first recess 110 for connecting the C-pillar and a second recess 120 for connecting the D-pillar to the rear wheel arch 100 improves the structural strength and torsional stiffness of the rear wheel arch 100. Adding a reinforcing structure 130 to the rear wheel arch 100 and connecting it with the first recess 110 and the second recess 120 to form a cross-force transmission structure (such as an "H" shape or an "I" shape) more effectively resists torsional moments, allowing the rear wheel arch 100 to better maintain structural stability and reduce deformation when subjected to torsional forces, thereby improving the torsional stiffness of the rear wheel arch 100. Therefore, the rear wheel arch provided in this embodiment solves the problem of insufficient torsional stiffness in the area of ​​the rear wheel arch connecting the C-pillar and D-pillar in the prior art, which affects vehicle safety.

[0049] Furthermore, the first recess 110, the second recess 120, and the reinforcing structure 130 form a cross-force transmission structure. When the rear wheel arch of this embodiment is assembled into the vehicle, this structure can effectively promote the mutual transmission and dispersion of loads between the C-pillar and the D-pillar, making the force path clearer and more continuous, thereby improving the torsional stiffness of the vehicle and enhancing the structural stability and safety of the vehicle under complex working conditions.

[0050] The top of the rear wheel cover 100 can be provided with a flange 140 extending outward along the height direction of the rear wheel cover 100. The first recessed portion 110 and the second recessed portion 120 can both extend along the height direction, and the top of the first recessed portion 110 and the top of the second recessed portion 120 can be shaped on the flange 140, so that the top of the first recessed portion 110 forms a C-pillar connecting surface 111 and the top of the second recessed portion 120 forms a D-pillar connecting surface 121. The C-pillar connecting surface 111 is used for abutting connection with the C-pillar, and the D-pillar connecting surface 121 is used for abutting connection with the D-pillar.

[0051] In the case where the top of the rear wheel cover 100 is not provided with the flange 140, the contact between the C-pillar and the first recessed portion 110 and the contact between the D-pillar and the second recessed portion 120 are line contacts. The addition of the flange 140 causes the top of the first recessed portion 110 to form the C-pillar connecting surface 111 on the flange 140 and causes the top of the second recessed portion 120 to form the D-pillar connecting surface 121 on the flange 140, so that the contact between the C-pillar and the C-pillar connecting surface 111 and the contact between the D-pillar and the D-pillar connecting surface 121 are surface contacts, thereby improving the connection strength and the connection stability of the C-pillar and the rear wheel cover 100 and the connection strength and the connection stability of the D-pillar and the rear wheel cover 100.

[0052] Optionally, the C-pillar and the C-pillar connecting surface 111 and the D-pillar and the D-pillar connecting surface 121 can be connected by bolt connection or welding.

[0053] In order to further improve the structural strength and the torsional stiffness of the rear wheel cover 100, the rear wheel cover 100 can be further provided with a first reinforcing rib 150, a second reinforcing rib 160, and a third reinforcing rib 170.

[0054] The boundary position of the first recessed portion 110 (i.e., the edge of the first recessed portion 110) and the boundary position of the second recessed portion 120 (i.e., the edge of the second recessed portion 120) can both be provided with the first reinforcing rib 150. The number of the first reinforcing ribs 150 is multiple, and at least part of the first reinforcing ribs 150 can extend along the height direction of the rear wheel cover 100. This structure helps to improve the local structural strength of the first recessed portion 110 and the second recessed portion 120, thereby improving the overall structural strength of the rear wheel cover 100.

[0055] Specifically, along the direction from the first recessed portion 110 to the second recessed portion 120, both sides of the first recessed portion 110 and both sides of the second recessed portion 120 can be provided with the first reinforcing rib 150 extending along the height direction. Of course, part of the multiple first reinforcing ribs 150 can also extend along a direction perpendicular to the height direction.

[0056] The interior of the first recess 110 and the second recess 120 can be provided with a second reinforcing rib 160, a first end of the second reinforcing rib 160 can be close to the reinforcing structure 130, or can be directly connected with the reinforcing structure 130, and a second end of the second reinforcing rib 160 can extend away from the reinforcing structure 130. In this case, on the one hand, the local structural strength of the first recess 110 and the second recess 120 can be improved, and on the other hand, the second reinforcing rib 160 can also guide the load from the reinforcing structure 130 to diffuse outward, thereby reducing stress concentration and improving the structural stability of the entire rear wheel cover 100.

[0057] Specifically, the second reinforcing rib 160 can include a first sub-rib 161 and a second sub-rib 162.

[0058] The first recess 110 can be provided with one or more first sub-ribs 161, and both ends of the first sub-rib 161 can be connected to two first reinforcing ribs 150 located at the two side edges (the two sides in the direction from the first recess 110 to the second recess 120) of the first recess 110 and extending in the height direction. Of course, the second recess 120 can also be provided with a first sub-rib 161, and both ends of the first sub-rib 161 in the second recess 120 can also be connected to two first reinforcing ribs 150 located at the two side edges (the two sides in the direction from the first recess 110 to the second recess 120) of the second recess 120 and extending in the height direction.

[0059] The first recess 110 and / or the second recess 120 can be provided with a second sub-rib 162, a first end of the second sub-rib 162 provided in the first recess 110 can be connected to one of the two first reinforcing ribs 150 located at the two side edges (the two sides in the direction from the first recess 110 to the second recess 120) of the first recess 110 and extending in the height direction, and a second end can be connected to the rear floor longitudinal beam 200 (see below). A first end of the second sub-rib 162 provided in the second recess 120 can be connected to one of the two first reinforcing ribs 150 located at the two side edges (the two sides in the direction from the first recess 110 to the second recess 120) of the second recess 120 and extending in the height direction, and a second end can be connected to the rear floor longitudinal beam 200.

[0060] In order to further improve the structural strength and torsional stiffness of the rear floor skeleton, the rear wheelhouse 100 can further be provided with a third reinforcing rib 170. The first recess 110 and the second recess 120 and the region therebetween form a first region in the direction from the first recess 110 to the second recess 120. The third reinforcing rib 170 can be located outside the first region. The first end of the third reinforcing rib 170 can be adjacent to the first region or can be directly connected to the first recess 110 or the second recess 120 (or the first reinforcing rib 150 located at the boundary of the two). The second end can extend away from the first region. In this case, on the one hand, the structural strength of the local region of the rear wheelhouse 100 where the third reinforcing rib 170 is located can be improved. On the other hand, the third reinforcing rib 170 can also guide the load from the first recess 110 or the second recess 120 to diffuse outward, reduce stress concentration, and improve the structural stability of the entire rear wheelhouse 100.

[0061] Of course, other reinforcing ribs extending in the height direction of the rear wheelhouse 100 or extending in a direction inclined to the height direction can also be provided in the first recess 110, the second recess 120 and the third recess, so as to improve the local structural strength of the first recess 110, the second recess 120 and the third recess, and help to disperse and transmit forces, thereby improving the torsional stiffness of the rear wheelhouse 100.

[0062] In the embodiments of the present application, the rear wheelhouse 100 can further include a shock absorber mounting area 180 for mounting a shock absorber by means of bolt connection or the like. The shock absorber mounting area 180 can be located in the region surrounded by the first recess 110, the second recess 120 and the reinforcing structure 130, and below the reinforcing structure 130 in the height direction of the rear floor skeleton.

[0063] In this case, after the rear wheelhouse 100 is connected to the shock absorber, the force received by the shock absorber can be transmitted upward to the reinforcing structure 130, and then be dispersed in two ways. One way is to pass through the reinforcing structure 130 and be transmitted to the C pillar mounted on the first recess 110 in sequence. The other way is to pass through the reinforcing structure 130 and be transmitted to the D pillar mounted on the second recess 120 in sequence. In this way, it is helpful to more evenly and fully distribute the force transmitted by the shock absorber.

[0064] As shown in FIG. 1, the rear wheelhouse 100 can further include a third reinforcing rib 170. The third reinforcing rib 170 can be located outside the first region formed by the first recess 110 and the second recess 120 and the region therebetween. The first end of the third reinforcing rib 170 can be adjacent to the first region or can be directly connected to the first recess 110 or the second recess 120 (or the first reinforcing rib 150 located at the boundary of the two). The second end of the third reinforcing rib 170 can extend away from the first region. Figures 5 to 6As shown, based on the rear wheel cover 100 described above, the embodiment of the present application further provides a rear floor framework, which comprises the rear floor longitudinal beams 200, the rear floor cross beams 300 and the rear floor framework described above, the rear floor cross beams 300 and the rear floor longitudinal beams 200 are connected to form a frame, and the rear wheel cover 100 is connected to the frame. Since the rear floor framework has the rear wheel cover 100 described above, the beneficial effects of the rear floor framework brought by the rear wheel cover 100 are described above and will not be repeated here.

[0065] Optionally, the number of the rear floor longitudinal beams 200 can be two, and the number of the rear floor cross beams 300 can be two or more than two. The two rear floor longitudinal beams 200 are arranged at intervals, and the two ends of each rear floor cross beam are respectively connected to the two rear floor longitudinal beams 200, so that the rear floor cross beams and the rear floor longitudinal beams 200 are connected to form a frame.

[0066] The rear floor framework can be an integrated structure. Optionally, the rear floor framework can be processed into an integrated structure by an integrated casting forming process. The rear floor framework can be made of aluminum material. The rear floor framework of this structure has high integration and is helpful to the lightweight design of the rear floor framework.

[0067] Of course, in other optional embodiments, the rear wheel cover 100 and the frame can be connected by bolt connection or welding. Alternatively, the rear wheel cover 100 can be integrally formed with the rear floor longitudinal beams 200, and the rear floor cross beams 300 and the rear floor longitudinal beams 200 are connected by bolt connection or welding.

[0068] The height direction of the rear wheel cover 100 can satisfy the vertical condition with the frame. The first recessed part 110 and the second recessed part 120 can extend along the height direction of the rear wheel cover 100, and the bottoms of the first recessed part 110 and the second recessed part 120 are adjacent to the frame, that is, the bottoms extend towards the direction close to the frame. In this case, the first recessed part 110 and the second recessed part 120 can serve as a force transmission path to effectively transmit the force (for example, the force from the C-pillar and the D-pillar) borne by the first recessed part 110 and the second recessed part 120 to the frame, thereby achieving further dispersion and transmission of the force and improving the overall torsional stiffness and structural stability of the rear floor framework.

[0069] It should be noted that the height direction of the rear wheel cover 100 satisfying the vertical condition with the frame means that the height direction of the rear wheel cover 100 is perpendicular to the frame. Alternatively, the height direction of the rear wheel cover 100 is substantially perpendicular to the frame, for example, the included angle between the height direction of the rear wheel cover 100 and the frame is less than 15 degrees.

[0070] The connection position of the rear wheel cover 100 and the frame has multiple options. In an alternative embodiment, the rear wheel cover 100 can be connected to the area of the rear floor longitudinal beam 200 that is not connected to the rear floor cross beam 300, so that the force borne by the first recess 110 and the second recess 120 can be transmitted to the rear floor longitudinal beam 200 and then to the rear floor cross beam 300.

[0071] In another alternative embodiment, the rear wheel cover 100 can be connected to the intersection area of the rear floor cross beam 300 and the rear floor longitudinal beam 200, that is, the area where the connection position of the rear floor cross beam and the rear floor longitudinal beam 200 is located, and the bottom of the first recess 110 and the second recess 120 can be adjacent to the rear floor cross beam 300. Compared with the technical solution in which the rear wheel cover 100 is connected to the area of the rear floor longitudinal beam 200 that is not connected to the rear floor cross beam 300, this structure enables the force borne by the first recess 110 and the second recess 120 to be transmitted more quickly to the rear floor longitudinal beam 200 and the rear floor cross beam 300, which helps to improve the torsional stiffness of the rear floor framework.

[0072] The number of the rear floor cross beams 300 can be at least two. Optionally, the bottom of the first recess 110 and the bottom of the second recess 120 can be adjacent to the same rear floor cross beam 300; or the bottom of the first recess 110 can be adjacent to one of the rear floor cross beams 300, and the bottom of the second recess 120 can be adjacent to another rear floor cross beam 300. This structure enables the load from the C-pillar and the D-pillar to be more evenly distributed on different rear floor cross beams, avoids overloading of a single component, and further improves the stability and torsional performance of the rear floor framework.

[0073] It should be noted that the height direction of the rear floor framework is consistent with the height direction of the rear wheel cover 100. When the rear floor framework is assembled on the vehicle, the height direction of the rear floor framework is consistent with the height direction of the vehicle.

[0074] As described above, the rear wheel cover 100 is also provided with the first reinforcing rib 150, the second reinforcing rib 160, and the third reinforcing rib 170. The first reinforcing rib 150 extends along the height direction, and the bottom of the first reinforcing rib 150 can be located on the rear floor longitudinal beam 200 and can penetrate through the rear floor longitudinal beam 200. The second end of at least part of the second reinforcing rib 160 can be connected to the rear floor longitudinal beam 200, so that the second reinforcing rib 160 connected to the rear floor longitudinal beam 200 can also guide the load from the reinforcing structure 130 to spread to the rear floor longitudinal beam 200; the second end of at least part of the third reinforcing rib 170 is connected to the rear floor longitudinal beam 200, thereby guiding the load to spread to the rear floor longitudinal beam 200.

[0075] In the embodiments of the present application, the local thickness of the rear wheel cover 100 and the height and thickness of various reinforcing ribs can be adjusted according to the CAE (Computer-Aided Engineering, which refers to a technology of modeling, simulating and analyzing engineering problems by using computer software) analysis result, so as to improve the overall performance of the rear wheel cover 100.

[0076] Based on the rear floor framework, the embodiments of the present application further provide a rear floor assembly, which comprises the rear floor framework and can further comprise a rear floor panel installed on the rear floor framework. Since the rear floor assembly has the rear floor framework, the beneficial effects of the rear floor assembly brought by the rear floor framework are described above and will not be repeated here.
