[0049] In order to more clearly understand the above purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein; Obviously, the examples in the specification are only some of the embodiments of the utility model, not all the embodiments.

[0051] At present, in the vehicle structure, the front extension plate of the rear wheel cover outer plate of the side wall assembly and the rear suspension longitudinal arm mounting plate are connected through lap joint. When the vehicle is stationary or driving on flat road, the rear suspension longitudinal arm mounting plate is subjected to upward force transmitted by the rear wheel suspension longitudinal arm, and part of the force is transmitted to the front extension plate of the rear wheel cover outer plate, at this time, the stress at the connection position of the front extension plate of the rear wheel cover outer plate and the rear suspension longitudinal arm mounting plate is relatively stable.

[0052] However, when a vehicle travels on bumpy roads, the suspension's shock absorbers and springs need to respond quickly to frequent road undulations, causing a significant increase in the amplitude and frequency of the suspension trailing arms' sway. This results in the rear suspension trailing arm mounting plate and the front extension plate of the rear wheel arch outer panel bearing considerable impact forces. Due to the relatively low strength at this connection point, it is prone to deformation under repeated impacts, leading to problems such as weld cracking and abnormal noises.

[0053] To address the aforementioned technical problems, this utility model provides a rear wheel arch outer panel assembly, a side panel assembly, and a vehicle. The following detailed description of the rear wheel arch outer panel assembly, side panel assembly, and vehicle provided by this utility model is based on the accompanying drawings.

[0054] Reference Figure 1 and Figure 2 The first aspect of this utility model provides a rear wheel arch outer panel assembly 1000, including: a rear wheel arch outer panel 10, a rear wheel arch outer panel front extension plate 11, and a rear wheel arch outer panel front section 12.

[0055] Among them, the rear wheel arch outer plate 10 has an inverted U-shaped structure, and an inverted U-shaped avoidance area is formed on its inner side. This provides ample installation and movement space for the rear wheel, wheel suspension trailing arm and other components (such as shock absorbers, springs, etc.). At the same time, the inverted U-shaped structure can maximize the use of the vehicle width and height in a limited space, making the layout of the rear wheel arch area more compact, without affecting the functionality of the suspension system.

[0056] The front extension plate 11 of the rear wheel cover outer panel is disposed inside the rear wheel cover outer panel 10 and extends along a first direction, wherein the first direction is the Y-Y1 or Y1-Y direction, and the extension length of the front extension plate 11 of the rear wheel cover outer panel can be set according to the actual situation.

[0057] The front section 12 of the rear wheel cover outer plate is located inside the rear wheel cover outer plate 10 and extends along the first direction. The front section 12 of the rear wheel cover outer plate at least partially overlaps the front extension plate 11 of the rear wheel cover outer plate. It is understood that the overlap can be a connection in the form of welding, bolting, riveting, etc. Welding is preferred. Compared with bolting and riveting, welding performs better in terms of bearing tensile and shear forces and can better meet the design requirements.

[0058] The tensile strength and yield strength of the front section 12 of the rear wheel arch outer plate are greater than those of the front extension plate 11 of the rear wheel arch outer plate. Tensile strength refers to the maximum stress that a material can withstand under tension, while yield strength is the stress value at which the material begins to undergo plastic deformation. Both tensile strength and yield strength can be determined by tensile testing.

[0059] Exemplarily, the rear wheel housing outer plate front extension plate 11 can adopt the material HC260YD+ZM, and the rear wheel housing outer plate front section 12 can adopt the high-strength material HC420DPD+Z or HC780DPD+Z, and it is only required to ensure that the tensile strength and yield strength of the rear wheel housing outer plate front section 12 are greater than those of the rear wheel housing outer plate front extension plate 11, and the material selected here can be selected according to the actual situation.

[0060] The side of the rear wheel housing outer plate front section 12 away from the rear wheel housing outer plate front extension plate 11 is in lap joint with the rear suspension trailing arm mounting plate 24, that is, it is known from the above description that the rear wheel housing outer plate front extension plate 11 is indirectly connected with the rear suspension trailing arm mounting plate 24 through the rear wheel housing outer plate front section 12, and the tensile strength and yield strength of the rear wheel housing outer plate front section 12 are greater than those of the rear wheel housing outer plate front extension plate 11, that is, the high-strength steel structure (rear wheel housing outer plate front section 12) is added to the weak stress point area of the connection position of the rear wheel housing outer plate front extension plate 11 and the rear suspension trailing arm mounting plate 24 in the prior art, so as to enhance the anti-deformation ability of the weak stress area, thereby improving the service life of the rear wheel housing outer plate assembly 1000.

[0061] Meanwhile, the rear wheel housing outer plate front section 12 is provided, which can increase the tensile strength and yield strength of the rear wheel housing outer plate assembly 1000 without changing the structure of other lap joint parts, thereby reducing the risk of damage of the rear wheel housing outer plate assembly 1000 during driving on a bumpy road section, and further reducing the risk of secondary injury, so as to improve the safety factor of the vehicle.

[0062] In addition, the rear wheel housing outer plate front section 12 is designed separately from the rear wheel housing outer plate front extension plate 11, which gives the rear wheel housing outer plate front section 12 greater modeling flexibility. This means that the thickness and plate model of the modeling structure of the rear wheel housing outer plate front section 12 can be flexibly adjusted according to the requirements of different collision levels, thereby improving the adaptability and resilience of the vehicle model to diversified safety standards.

[0063] Further, the rear wheel housing outer plate 10, the rear wheel housing outer plate front extension plate 11 and the rear wheel housing outer plate front section 12 in the above embodiment are all formed by stamping.

[0064] Compared with the prior art, the material of the rear wheel cover outer plate front extension plate 11 is changed to high-strength steel as a whole to enhance the stress strength, thereby improving the deformation resistance of the connection between the rear wheel cover outer plate front extension plate 11 and the rear suspension longitudinal arm mounting plate 24. However, since the rear wheel cover outer plate front extension plate 11 needs to be hemmed between the side outer plate 20, the hemming surface precision of the rear wheel cover outer plate front extension plate 11 is required to be high. Therefore, if the material of the rear wheel cover outer plate front extension plate 11 is changed to high-strength steel as a whole, a drawing process scheme needs to be used. However, since the size of the rear wheel cover outer plate front extension plate 11 is small, and the drawing performance of high-strength steel is poor, the production stability and precision stability of the rear wheel cover outer plate front extension plate 11 cannot be guaranteed, thereby affecting the later installation and use.

[0065] The rear wheel cover outer plate front section 12 made of high-strength steel is arranged at the weak stress point region, without changing the material of the original rear wheel cover outer plate front extension plate 11, so that the rear wheel cover outer plate front extension plate 11 can normally use a stamping process. Since the rear wheel cover outer plate front section 12 does not need to be hemmed, the stamping process can also be used, without using the drawing process. Therefore, the problem that the production stability and precision stability cannot be guaranteed due to the change of the strength of the rear wheel cover outer plate front extension plate 11 in the prior art is solved, thereby improving the deformation resistance of the rear wheel cover assembly 1000 when impacted.

[0066] In addition, the increase in the strength of the single-piece region (the rear wheel cover outer plate front section 12) can effectively reduce the cost compared with the increase in the strength of the whole rear wheel cover outer plate front extension plate 11. Since the rear wheel cover outer plate front section 12, the rear wheel cover outer plate 10, the rear wheel cover outer plate front extension plate 11, and the rear wheel cover outer plate front section 12 are all formed by stamping, the impact resistance is guaranteed, the development difficulty is reduced, the production cycle is shortened, and the development cost is reduced.

[0067] Further, referring to Figure 1 The rear wheel cover outer plate 10 is provided with a first hem 100 folded inwardly, and the first hem 100 extends along the bending direction of the rear wheel cover outer plate 10. The rear wheel cover outer plate front extension plate 11 is provided with a second hem 112 folded inwardly, and the second hem 112 extends along the first direction and is connected to the first hem 100 at one end. The first hem 100 and the second hem 112 can be formed by stamping together with the rear wheel cover outer plate 10 and the rear wheel cover outer plate front extension plate 11, thereby reducing the development cost and shortening the construction period.

[0068] In the above scheme, the first flanging 100 and the second flanging 112 jointly form the flanging surface of the rear wheel cover outer plate assembly 1000, which facilitates the subsequent covering and flanging of the relevant components in the side wall assembly 2000, details of which can be seen from the following textual description of the side wall assembly 2000, so as to improve the connection stability between the side wall assembly 2000 and the rear wheel cover outer plate assembly 1000, and at the same time, the flanging surface of the rear wheel cover outer plate assembly 1000 is subjected to the flanging treatment, which can also improve the aesthetic appearance of the rear wheel cover outer plate assembly 1000.

[0069] With reference to the foregoing Figure 2 and Figure 3 In some embodiments of the present application, the rear wheel cover outer plate front extension plate 11 is provided with a first protruding portion 110, and the back of the rear wheel cover outer plate front section 12 is provided with a first recessed portion 120. It can be understood that the back of the rear wheel cover outer plate front section 12 refers to the side of the rear wheel cover outer plate front section 12 close to the rear wheel cover outer plate 10.

[0070] The first protruding portion 110 is lapped in the first recessed portion 120, wherein the first protruding portion 110 and the first recessed portion 120 are matched in shape.

[0071] In the above technical solution, the first protruding portion 110 and the first recessed portion 120 can be formed by stamping, and by providing the first protruding portion 110 and the first recessed portion 120, the physical limit is formed by the fitting of the protrusion and the recess, which can effectively resist the risk of transverse displacement or misplacement caused by vibration or impact during assembly or use, and ensure the long-term stability of the connection between the rear wheel cover outer plate front extension plate 11 and the rear wheel cover outer plate front section 12.

[0072] Secondly, the first recessed portion 120 provides a precise guide reference for the first protruding portion 110, significantly reducing the adjustment difficulty during assembly, improving the installation efficiency and position accuracy, and avoiding errors caused by repeated manual calibration.

[0073] For reference Figure 4 In some embodiments of the present application, the first protruding portion 110 is formed with a second recessed portion 111 at the back, wherein it can be understood that the second recessed portion 111 is a recessed area formed after the first protruding portion 110 is stamped inwardly to the rear wheel cover outer plate 10, and the second recessed portion 111 reserves an ideal lapping area for subsequent lapping with the relevant components in the side wall assembly 2000, and simultaneously serves as a guide positioning function, which can be further referred to the detailed description of the side wall assembly 2000 below.

[0074] For reference Figure 2 , Figure 3 and Figure 5In some embodiments of the utility model, first lap joint part 113 is equipped on rear wheel cover outer plate front extension plate 11, second lap joint part 121 is arranged on the edge of rear wheel cover outer plate front section 12 and is located at the top of first recessed part 120, and second lap joint part 121 is lapped on first lap joint part 113.

[0075] In the above technical solution, the setting of first lap joint part 113 and second lap joint part 121 makes the connection between rear wheel cover outer plate front section 12 and rear wheel cover outer plate front extension plate 11, in addition to the embedding of first protruding part 110 and first recessed part 120, also increases the additional lap joint area, which helps to further enhance the connection firmness between the two, and ensures that the connection can remain stable in complex and changeable driving environment.

[0076] Meanwhile, second lap joint part 121 is located directly above first recessed part 120, which provides a clear positioning reference for the assembly process. Workers can easily identify the corresponding relationship between second lap joint part 121 and first protruding part 110 / second recessed part 111 during assembly, thereby ensuring the accuracy and precision of assembly. Moreover, second lap joint part 121 is located directly above first recessed part 120, forming a vertical mechanical transmission path, which can uniformly transmit external impact load to adjacent components (for example, rear wheel cover outer plate 10) through the synergistic action of second lap joint part 121 and first recessed part 120, avoiding local stress concentration and improving structural strength.

[0077] In some embodiments of the utility model, third flanging 122 is folded inwardly from rear wheel cover outer plate front section 12 to rear wheel cover outer plate 10 and extends in the first direction. Third flanging 122 can be formed synchronously with rear wheel cover outer plate front section 12 through a single stamping process without additional processing steps, which is highly compatible with the overall manufacturing process and reduces process complexity.

[0078] In the above technical solution, third flanging 122 provides a clear lap joint interface for related components in side wall assembly 2000, which can be specifically described in the following text for side wall assembly 2000. Without additional processing or adjustment, it can be quickly assembled, significantly improving production efficiency.

[0079] In addition, the flanging structure of third flanging 122 increases the contact area with related components in side wall assembly 2000, effectively inhibiting the relative displacement of the lap joint area and improving the vibration resistance and impact resistance of the connection part.

[0080] The following Figures 6 to 13 The specific structure of side wall assembly 2000 is introduced in detail.

[0081] Referring to Figures 6 to 9The utility model discloses a second aspect provides a kind of side wall assembly 2000 including side wall outer plate 20, sill beam 21, rear floor longitudinal beam front section 22, rear suspension arm mounting reinforcement plate 23, rear suspension arm mounting plate 24 and the rear wheel cover outer plate assembly 1000 described in any of the above first aspect.

[0082] Wherein, side wall outer plate 20 is installed on the outside of rear wheel cover outer plate assembly 1000, in other words, rear wheel cover outer plate assembly 1000 is embedded on the inside area of side wall outer plate 20, that is, side wall outer plate 20 provides installation area for rear wheel cover outer plate assembly 1000, and the installation area, rear wheel cover outer plate assembly 1000 and the shape of rear wheel are matched, wherein, side wall outer plate 20 is also provided with two door frame mounting openings shaped with door, for providing installation basis for door. It can be understood that the outside of rear wheel cover outer plate assembly 1000 refers to the upper side of rear wheel cover outer plate assembly 1000, which can also be understood with reference to the direction of Y1-Y in the figure. Figure 6

[0083] It should be noted that, with reference to Figure 10 , the area of side wall outer plate 20 close to rear wheel cover outer plate assembly 1000 is folded in the direction of rear wheel cover outer plate assembly 1000 with edge 200 to cover first edge 100 and second edge 112, enough to support and stabilize rear wheel cover outer plate assembly 1000 upward, prevent rear wheel cover outer plate assembly 1000 from sinking or displacement due to vibration or impact, improve the stability when connecting rear wheel cover outer plate assembly 1000, while edge 200 covers first edge 100 and second edge 112, avoids the joint exposed, makes the transition of rear wheel cover outer plate assembly 1000 and side wall outer plate 20 more smooth and natural, significantly improves the appearance of the vehicle.

[0084] With reference to Figure 8 and Figure 9 , sill beam 21 is arranged on side wall outer plate 20, and sill beam 21 overlaps with rear wheel cover outer plate front extension plate 11 and rear wheel cover outer plate front section 12, wherein, sill beam 21 is arranged on the side of side wall outer plate 20 close to seat, and sill beam 21 is used to reinforce rear wheel cover outer plate front extension plate 11, rear wheel cover outer plate front section 12 and rear suspension arm mounting plate 24, and provide installation basis for rear floor longitudinal beam front section 22.
