The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] Reference below Figure 1-Figure 16 A reinforcement structure 3 according to an embodiment of the present invention is described.

[0053] like Figure 1-Figure 16 As shown, the reinforcement structure 3 according to the embodiment of the present invention includes: a first reinforcement 31, the first reinforcement 31 extends along the height direction of the vehicle; a second reinforcement 32 and a third reinforcement 33, the second reinforcement 32 and the third reinforcement 33 both extend obliquely along the length direction of the vehicle, the second reinforcement 32 and the third reinforcement 33 are located on the same side of the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33 are fixedly connected, and an angle is formed between the second reinforcement 32 and the third reinforcement 33, and the third reinforcement 33 is fixedly connected to the first reinforcement 31.

[0054] The vehicle may include a vehicle body 1 and a rear wheel housing 2, wherein the rear wheel housing 2 and the vehicle body 1 are fixedly connected, a reinforcement structure 3 is fixedly arranged on the inner surface of the rear wheel housing 2, and the reinforcement structure 3 is fixedly connected to the vehicle body 1. A mounting seat 4 is fixedly arranged on the outer surface of the rear wheel housing 2, and the mounting seat 4 is used to install parts. The vehicle body 1 includes a C-pillar 15, a D-pillar 16, a rear longitudinal beam 12, and a corner window lower cross beam 11. Along the length direction of the vehicle, the D-pillar 16 is arranged on the side of the C-pillar 15 away from the front of the vehicle, and the corner window lower cross beam 11 is arranged between the C-pillar 15 and the D-pillar 16, and the corner window lower cross beam 11 and the C-pillar 15 and the D-pillar 16 can be connected by welding, but not limited to, and the rear longitudinal beam 12 and the C-pillar 15 and the D-pillar 16 can also be connected by welding, but not limited to. Along the height direction of the vehicle, the rear longitudinal beam 12 is arranged on the lower side of the corner window lower cross beam 11. Along the length direction of the vehicle, at least a portion of the rear wheel cover 2 is arranged between the C-pillar 15 and the D-pillar 16, and along the height direction of the vehicle, the rear wheel cover 2 is arranged between the lower cross beam 11 of the corner window and the rear longitudinal beam 12, and can be connected to the lower cross beam 11 of the corner window by but not limited to welding, so that the rear wheel cover 2 and the vehicle body 1 are fixedly connected.

[0055] The reinforcing structure 3 is fixed to the inner surface of the rear wheel cover 2, that is, the reinforcing structure 3 is fixed to the side surface of the rear wheel cover 2 facing the passenger compartment, and the reinforcing structure 3 is fixedly connected to the vehicle body 1. For example, the reinforcing structure 3 and the vehicle body 1 can be connected by welding, or by riveting. The present application takes the reinforcing structure 3 and the vehicle body 1 connected by welding as an example. The welding connection can improve the connection reliability between the reinforcing structure 3 and the vehicle body 1 and reduce the risk of separation between the reinforcing structure 3 and the vehicle body 1.

[0056] The reinforcing structure 3 includes a first reinforcement 31, a second reinforcement 32 and a third reinforcement 33. The first reinforcement 31 extends along the height direction of the vehicle, and along the height direction of the vehicle, the upper end of the first reinforcement 31 can be welded to the lower cross beam 11 of the corner window, and the lower end of the first reinforcement 31 can be welded to the rear longitudinal beam 12, so that the first reinforcement 31 can be reliably fixed to the inner surface of the rear wheel cover 2.

[0057] The second reinforcement 32 and the third reinforcement 33 are located on the same side of the first reinforcement 31, for example, along the length direction of the vehicle, the second reinforcement 32 and the third reinforcement 33 are both located on the front side of the first reinforcement 31, or the second reinforcement 32 and the third reinforcement 33 are both located on the rear side of the first reinforcement 31. The second reinforcement 32 and the third reinforcement 33 are fixedly connected, for example, the second reinforcement 32 and the third reinforcement 33 are welded, and the second reinforcement 32 and the third reinforcement 33 can also be connected by bolts to improve the connection reliability of the second reinforcement 32 and the third reinforcement 33.

[0058] The second reinforcement 32 and the third reinforcement 33 both extend obliquely along the length direction of the vehicle, for example: from the rear of the vehicle to the head of the vehicle, the second reinforcement 32 and the third reinforcement 33 extend obliquely in directions away from each other, so that an angle is formed between the second reinforcement 32 and the third reinforcement 33, and the third reinforcement 33 is fixedly connected to the first reinforcement 31, so that a continuous force transmission path can be formed between the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, that is, a first force transmission path is formed between the lower cross beam 11 of the corner window-the second reinforcement 32-the third reinforcement 33-the rear seat cross beam 13, thereby improving the torsional stiffness of the rear wheel cover 2, and a second force transmission path is formed between the lower cross beam 11 of the corner window-the first reinforcement 31-the rear longitudinal beam 12, thereby improving the stiffness of the rear wheel cover 2, thereby effectively improving the torsional stiffness and strength of the rear wheel cover 2 area of ​​the vehicle, reducing the risk of deformation or even cracking in the rear wheel cover 2 area, thereby improving the reliability and safety of the vehicle.

[0059] By fixing the reinforcing structure 3 on the inner surface of the rear wheel cover 2 and fixedly connecting the reinforcing structure 3 to the vehicle body 1, the stress on the rear wheel cover 2 can be transferred to the vehicle body 1 through the reinforcing structure 3, which is beneficial to reducing the risk of stress concentration in the rear wheel cover 2, thereby reducing the risk of deformation or even cracking in the rear wheel cover 2 area, and improving the fatigue durability and reliability of the rear wheel cover 2 area.

[0060] The mounting seat 4 is fixed on the outer surface of the rear wheel housing 2, that is, the mounting seat 4 is fixed on the side surface of the rear wheel housing 2 away from the passenger compartment. Along the height direction of the vehicle, the lower end of the mounting seat 4 can extend to the rear longitudinal beam 12, and can be connected to the rear longitudinal beam 12 by, but not limited to, welding, riveting, etc. The mounting seat 4 is used to install parts, for example: the mounting seat 4 can be used to install parts such as shock absorber supports. This application uses the mounting seat 4 for installing shock absorber supports as an example for explanation. The shock absorber supports are installed on the mounting seat 4. The mounting seat 4 can transfer the stress to the rear longitudinal beam 12, and can also be transferred to the reinforcement structure 3 through the rear wheel housing 2, so that the stress on the mounting seat 4 can be dispersed and transferred to the vehicle body 1 through the rear longitudinal beam 12 and the reinforcement structure 3, respectively, thereby improving the rigidity, strength and durability of the mounting seat 4 area, and also helping to improve the stability of the shock absorber support.

[0061] Specifically, the rear wheel cover 2 is welded to the vehicle body 1, and a reinforcement structure 3 is welded to the side surface of the rear wheel cover 2 facing the passenger compartment. Along the height direction of the vehicle, the upper end of the first reinforcement 31 is welded to the lower cross beam 11 of the corner window, and the lower end of the first reinforcement 31 is welded to the rear longitudinal beam 12. A mounting seat 4 is welded to the side surface of the rear wheel cover 2 away from the passenger compartment, and along the height direction of the vehicle, the lower end of the mounting seat 4 is welded to the rear longitudinal beam 12. The mounting seat 4 is used to install the shock absorber support. By providing the mounting seat 4 and installing the shock absorber support on the rear wheel cover 2 through the mounting seat 4, the risk of poor stiffness and strength of the shock absorber support installation point can be reduced, thereby optimizing the vehicle NVH (noise, vibration and harshness) performance and dynamic handling performance.

[0062] Along the length direction of the vehicle, the second reinforcement 32 and the third reinforcement 33 are located in front of the first reinforcement 31, and the second reinforcement 32 and the third reinforcement 33 are welded and connected, and the third reinforcement 33 and the first reinforcement 31 are welded and connected. From the rear of the vehicle to the head of the vehicle, the second reinforcement 32 and the third reinforcement 33 extend obliquely in a direction away from each other, so that an angle is formed between the second reinforcement 32 and the third reinforcement 33. Such a configuration can make the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, and the second reinforcement 32 and the third reinforcement 33 arranged reasonably, which is conducive to forming a continuous force transmission path between the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, thereby effectively improving the torsional rigidity and strength of the rear wheel cover 2 area of ​​the vehicle, and reducing the risk of deformation or even cracking of the rear wheel cover 2 area.

[0063] Therefore, by setting the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, the second reinforcement 32 and the third reinforcement 33 are fixedly connected, the third reinforcement 33 and the first reinforcement 31 are fixedly connected, and an angle is formed between the second reinforcement 32 and the third reinforcement 33, a continuous force transmission path can be formed between the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, thereby effectively improving the torsional stiffness and strength of the rear wheel cover 2 area of ​​the vehicle, reducing the risk of deformation or even cracking in the rear wheel cover 2 area, thereby improving the reliability and safety of the vehicle.

[0064] In some embodiments of the present invention, Figure 1 As shown, the second reinforcement 32 extends obliquely upward along the length direction of the vehicle, and the third reinforcement 33 extends obliquely downward along the length direction of the vehicle.

[0065] Among them, along the length direction of the vehicle, the second reinforcement member 32 can extend obliquely upward to the corner window lower cross beam 11, and the second reinforcement member 32 and the corner window lower cross beam 11 can be fixedly connected by, but not limited to, welding or riveting. Along the extension direction of the second reinforcement member 32, one end of the second reinforcement member 32 away from the corner window lower cross beam 11 can be fixedly connected to the third reinforcement member 33 by, but not limited to, welding or riveting. Along the length direction of the vehicle, the third reinforcement 33 can extend obliquely downward to the rear seat cross beam 13, and the third reinforcement 33 and the rear seat cross beam 13 can be fixedly connected by but not limited to welding or riveting. Along the extension direction of the third reinforcement 33, the end of the third reinforcement 33 away from the rear seat cross beam 13 can be fixedly connected to the first reinforcement 31 by but not limited to welding or riveting, so that a first force transmission path is formed between the lower cross beam 11 of the corner window-the second reinforcement 32-the third reinforcement 33-the rear seat cross beam 13, which can improve the torsional stiffness of the rear wheel cover 2, and a second force transmission path is formed between the lower cross beam 11 of the corner window-the first reinforcement 31-the rear longitudinal beam 12, which can improve the stiffness of the rear wheel cover 2, thereby effectively improving the torsional stiffness and strength of the rear wheel cover 2 area of ​​the vehicle, reducing the risk of deformation or even cracking in the rear wheel cover 2 area, thereby improving the reliability and safety of the vehicle.

[0066] In some embodiments of the present invention, Figure 1 and Fig.12 As shown, the third reinforcement 33 includes: a first sub-reinforcement 331 and a second sub-reinforcement 332 , the first sub-reinforcement 331 is connected between the first reinforcement 31 and the second sub-reinforcement 332 , and an angle is formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 .

[0067] Wherein, as some embodiments of the present application, the first sub-reinforcement 331 and the second sub-reinforcement 332 are integrally formed. As some embodiments of the present application, the first sub-reinforcement 331 and the second sub-reinforcement 332 are welded and connected, so that the first sub-reinforcement 331 is connected to the second sub-reinforcement 332. The first sub-reinforcement 331 is connected to the first reinforcement 31, for example: the first sub-reinforcement 331 and the first reinforcement 31 can be welded and connected, and the first sub-reinforcement 331 and the first reinforcement 31 can also be riveted and connected, so that the first sub-reinforcement 331 is connected between the first reinforcement 31 and the second sub-reinforcement 332.

[0068] The second sub-reinforcement 332 is connected to the rear seat cross beam 13. For example, the second sub-reinforcement 332 is directly connected to the rear seat cross beam 13. The second sub-reinforcement 332 and the rear seat cross beam 13 can also be indirectly connected through the C ring 14. Such an arrangement can make the structural arrangement of the third reinforcement 33 reasonable. By connecting the third reinforcement 33 with the first reinforcement 31 and the second reinforcement 32, the integrity of the reinforcement structure 3 can be improved. The first reinforcement 31, the second reinforcement 32 and the third reinforcement 33 can also be connected, thereby forming a force transmission channel between each other, which is beneficial to improving the stiffness and strength of the reinforcement structure 3, thereby improving the torsional stiffness of the rear wheel cover 2 area.

[0069] An angle β1 is formed between the first sub-reinforcement 331 and the second sub-reinforcement 332, and β1 can satisfy the relationship: 0°≤β1≤180°, that is, the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 is greater than or equal to 0° and less than or equal to 180°. For example, the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 can be 0°, 120° or 180°, so that the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 can be flexibly adjusted according to different vehicle models, so that the reinforcement structure 3 can adapt to different vehicle models, which is conducive to improving the layout flexibility and versatility of the reinforcement structure 3.

[0070] In some embodiments of the present invention, Figure 1 and Fig.12 As shown, the first sub-reinforcement 331 extends along the length direction of the vehicle, and the second sub-reinforcement 332 extends obliquely downward along the length direction of the vehicle.

[0071] Among them, along the length direction of the vehicle, the first sub-reinforcement 331 is extended, and the second sub-reinforcement 332 is inclined and extended downward, so that the structural design of the third reinforcement 33 is reasonable, so that the third reinforcement 33 can be smoothly connected between the first reinforcement 31 and the rear seat cross beam 13, further improving the reliability of the reinforcement structure 3. The second reinforcement 32 is connected to the connection between the first sub-reinforcement 331 and the second sub-reinforcement 332, so that the third reinforcement 33 can be connected to both the first reinforcement 31 and the second reinforcement 32, thereby forming a mutual force transmission channel, which is conducive to improving the rigidity and strength of the reinforcement structure 3, thereby improving the torsional rigidity of the rear wheel housing 2 area.

[0072] According to the rear wheel cover assembly 200 of the embodiment of the present invention, Figure 1 As shown, the rear wheel cover assembly 200 includes: a rear wheel cover 2; a reinforcing structure 3, which is the reinforcing structure 3 of the above-mentioned embodiment, and is fixedly arranged on the inner surface of the rear wheel cover 2.

[0073] Among them, the rear wheel cover 2 is welded to the vehicle body 1, and the reinforcement structure 3 is fixed to the inner surface of the rear wheel cover 2, that is, the reinforcement structure 3 is fixed to the surface of the rear wheel cover 2 facing the passenger compartment. For example, the reinforcement structure 3 and the rear wheel cover 2 can be connected by welding, or by riveting. This application takes the reinforcement structure 3 and the rear wheel cover 2 as an example for explanation. The welding connection can improve the connection reliability of the reinforcement structure 3 and the rear wheel cover 2 and reduce the risk of separation of the reinforcement structure 3 and the vehicle body 1. Along the height direction of the vehicle, the upper end of the reinforcement structure 3 is welded to the lower cross beam 11 of the corner window, and the lower end of the reinforcement structure 3 is welded to the rear longitudinal beam 12.

[0074] Therefore, by making the reinforcing structure 3 securely fixed to the inner surface of the rear wheel cover 2, the torsional stiffness and strength of the rear wheel cover 2 can be effectively improved, reducing the risk of deformation or even cracking in the rear wheel cover 2 area, thereby improving the reliability and safety of the vehicle.

[0075] In some embodiments of the present invention, Figure 1 As shown, the vehicle includes a corner window lower cross beam 11 and a rear longitudinal beam 12, the corner window lower cross beam 11 is located above the rear longitudinal beam 12, the rear wheel cover 2 is used to be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12, the first reinforcement 31 is used to be connected to the corner window lower cross beam 11 and the rear longitudinal beam 12, and the second reinforcement 32 is used to be connected to the corner window lower cross beam 11.

[0076] The vehicle includes a corner window lower cross beam 11 and a rear longitudinal beam 12. Further, the vehicle body 1 includes a corner window lower cross beam 11 and a rear longitudinal beam 12. Along the height direction of the vehicle, the corner window lower cross beam 11 is located above the rear longitudinal beam 12. The rear wheel cover 2 is fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12. For example, the rear wheel cover 2 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by welding, and the rear wheel cover 2 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by rivets. The first reinforcement 31 is fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12. For example, the first reinforcement 31 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by welding, and the first reinforcement 31 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by rivets. The second reinforcement 32 is connected to the corner window lower cross beam 11 . For example, the second reinforcement 32 and the corner window lower cross beam 11 may be connected by, but not limited to, welding or riveting, so that the reinforcement structure 3 is reliably connected between the corner window lower cross beam 11 and the rear longitudinal beam 12 .

[0077] Specifically, along the height direction of the vehicle, the upper end of the first reinforcement 31 is welded to the lower cross beam 11 of the corner window, and the lower end of the first reinforcement 31 is welded to the rear longitudinal beam 12, so that the first reinforcement 31 is reliably fixed to the inner surface of the rear wheel housing 2. One end of the second reinforcement 32 is welded to the lower cross beam 11 of the corner window, and the other end of the second reinforcement 32 is welded to the third reinforcement 33, so that a first force transmission path is formed between the lower cross beam 11 of the corner window-the second reinforcement 32-the third reinforcement 33-the rear seat cross beam 13 to improve the torsional rigidity of the rear wheel housing 2, and a second force transmission path is formed between the lower cross beam 11 of the corner window-the first reinforcement 31-the rear longitudinal beam 12 to improve the rigidity of the rear wheel housing 2, thereby effectively improving the torsional rigidity and strength of the rear wheel housing 2 area of ​​the vehicle, reducing the risk of deformation or even cracking of the rear wheel housing 2 area, thereby improving the reliability and safety of the vehicle.

[0078] By forming a force transmission path between the lower cross beam 11 of the corner window, the reinforcing structure 3 and the rear longitudinal beam 12, the stress in the rear wheel cover 2 area can be transferred to the lower cross beam 11 of the corner window and the rear longitudinal beam 12 through the reinforcing structure 3, and then to the vehicle body 1, thereby reliably reducing the risk of stress concentration in the rear wheel cover 2, thereby reducing the risk of deformation or even cracking in the rear wheel cover 2 area, and improving the fatigue durability and reliability of the rear wheel cover 2 area.

[0079] In some embodiments of the present invention, Figure 1 As shown, the vehicle further includes a rear seat cross beam 13 , which is connected to the rear longitudinal beam 12 , and the third reinforcement 33 is used to be connected to the rear seat cross beam 13 .

[0080] The vehicle further includes a rear seat cross beam 13. Further, the vehicle body 1 may also include a rear seat cross beam 13, which extends in the width direction of the vehicle. The rear seat cross beam 13 and the rear longitudinal beam 12 may be connected by, but not limited to, welding, clamping, etc. As some embodiments of the present application, the reinforcing structure 3 and the rear seat cross beam 13 may be directly connected. As some embodiments of the present application, the reinforcing structure 3 and the rear seat cross beam 13 may be indirectly connected via a C ring 14. Such an arrangement may form a continuous force transmission structure between the C-pillar 15, the lower cross beam 11 of the corner window, the second reinforcement 32, the third reinforcement 33, the C ring 14 and the rear seat cross beam 13, which is beneficial for the stress in the rear wheel cover 2 area to be transmitted through the continuous structure, thereby reducing the risk of stress concentration in the rear wheel cover 2 and improving the reliability of the rear wheel cover 2 area.

[0081] In some embodiments of the present invention, Figure 4-Figure 6 As shown, a first cavity 35 is formed between the reinforcing structure 3 and the rear wheel housing 2 .

[0082] Among them, a first cavity 35 is formed between the reinforcing structure 3 and the rear wheel cover 2. For example, the reinforcing structure 3 can form the first cavity 35, the rear wheel cover 2 can form the first cavity 35, or the reinforcing structure 3 and the rear wheel cover 2 jointly define the first cavity 35. By forming the first cavity 35 between the reinforcing structure 3 and the rear wheel cover 2, the structural strength, rigidity and body torsional rigidity of the rear wheel cover 2 area can be improved, thereby improving the dynamic handling performance of the rear wheel cover assembly 200. The first cavity 35 can also block the force transmission path of the noise, reduce the noise transmitted to the passenger compartment during vehicle driving, and thus improve the NVH performance of the vehicle.

[0083] In some embodiments of the present invention, Figure 2 and Figure 6 As shown, the rear wheel cover assembly 200 may also include: a mounting seat 4, which is fixed to the outer surface of the rear wheel cover 2, and is used to install components. A second cavity 41 is formed between the mounting seat 4 and the rear wheel cover 2, and the first cavity 35 and the second cavity 41 have an overlapping area along the width direction of the vehicle.

[0084] Among them, the mounting seat 4 is fixed on the outer surface of the rear wheel cover 2, that is, the mounting seat 4 is fixed on the side surface of the rear wheel cover 2 away from the passenger compartment. Along the height direction of the vehicle, the lower end of the mounting seat 4 can extend to the rear longitudinal beam 12, and can be connected to the rear longitudinal beam 12 by, but not limited to, welding, riveting, etc. The mounting seat 4 is used to install parts, for example: the mounting seat 4 can be used to install parts such as shock absorber supports. This application uses the mounting seat 4 for installing shock absorber supports as an example for explanation. The shock absorber support is installed on the mounting seat 4. The mounting seat 4 can transfer the stress to the rear longitudinal beam 12, and can also be transferred to the reinforcement structure 3 through the rear wheel cover 2, so that the stress on the mounting seat 4 can be dispersed and transferred to the vehicle body 1 through the rear longitudinal beam 12 and the reinforcement structure 3, respectively, thereby improving the rigidity, strength and durability of the mounting seat 4 area, and also helping to improve the stability of the shock absorber support.

[0085] A second cavity 41 is formed between the mounting seat 4 and the rear wheel cover 2. For example, the mounting seat 4 can form the second cavity 41, the rear wheel cover 2 can form the second cavity 41, or the mounting seat 4 and the rear wheel cover 2 jointly define the second cavity 41. By forming the second cavity 41 between the mounting seat 4 and the rear wheel cover 2, the stiffness, strength and durability of the mounting seat 4 area can be improved, which is also beneficial to improving the stability of the shock absorber support.

[0086] The first cavity 35 and the second cavity 41 have an overlapping area along the width direction of the vehicle, for example: a first sub-cavity 351 and a second sub-cavity 411 are correspondingly arranged along the width direction of the vehicle, or part of the first sub-cavity 351 and part of the second sub-cavity 411 overlap along the width direction of the vehicle, so that the first cavity 35 and the second cavity 41 echo each other on both sides of the rear wheel cover 2, which is equivalent to enlarging the cross-sectional area of ​​the C-ring 14 on the force transmission path of the torsional C-pillar 15, the lower cross beam 11 of the corner window, the reinforcement structure 3, the C-ring 14 and the rear seat cross beam 13. The enlargement of the cross-sectional area of ​​the C-ring 14 can increase the sectional moment of inertia, thereby increasing the torsional stiffness of the rear wheel cover 2 area.

[0087] In some embodiments of the present invention, Figure 6 and Fig.14 As shown, the mounting seat 4 is connected to the reinforcement structure 3 .

[0088] The cross-sectional shape of the mounting seat 4 may be a double "J" shape, and the mounting seat 4 structure may include a fourth top welding edge 42, a fourth bottom welding edge 43, a fourth front welding edge 44, a fourth rear welding edge 45, a fourth middle welding edge 46, a convex peak 47 and a side wall 48. In the length direction of the vehicle, the fourth front welding edge 44 is arranged on the side of the fourth rear welding edge 45 close to the front of the vehicle, and the fourth middle welding edge 46 is arranged between the fourth top welding edge 42 and the fourth rear welding edge 45. In the height direction of the vehicle, the fourth top welding edge 42 is arranged on the upper side of the fourth bottom welding edge 43, and the fourth middle welding edge 46 is arranged between the fourth top welding edge 42 and the fourth bottom welding edge 43. The number of the side walls 48 is set to four. In the length direction of the vehicle, the two side walls 48 close to the front of the vehicle are connected to form a convex peak 47, and the two side walls 48 close to the rear of the vehicle are connected to form a convex peak 47. A groove is formed between the two convex peaks 47. Such a setting can make the structure of the mounting seat 4 reasonable and facilitate the installation of the shock absorber support.

[0089] The fourth top welding edge 42 and the fourth rear welding edge 45 are both welded to the reinforcement structure 3 and the rear wheel cover 2, so that the mounting seat 4 is connected to the reinforcement structure 3, for example: the fourth top welding edge 42 and the fourth rear welding edge 45 are both connected to the reinforcement structure 3 and the rear wheel cover 2 by three-layer spot welding. The mounting seat 4 and the reinforcement structure 3 can also be connected by bolts, and the bolts are penetrated through the mounting seat 4, the rear wheel cover 2 and the reinforcement structure 3. When the shock absorber support is installed on the mounting seat 4, the mounting seat 4 can transfer the stress to the rear wheel cover 2 and the reinforcement structure 3, so that the stress of the mounting seat 4 can be dispersed and transferred to the vehicle body 1, thereby improving the rigidity, strength and durability of the mounting seat 4 area, and also helping to improve the stability of the shock absorber support.

[0091] The vehicle body 1 includes a corner window lower cross beam 11 and a rear longitudinal beam 12. Along the height direction of the vehicle, the corner window lower cross beam 11 is located above the rear longitudinal beam 12. The rear wheel cover 2 is fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12. For example, the rear wheel cover 2 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by welding, and the rear wheel cover 2 can be fixedly connected to the corner window lower cross beam 11 and the rear longitudinal beam 12 by rivets.

[0099] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the reinforcement structure 3 may further include: a third reinforcement 33 , the third reinforcement 33 is connected to both the first reinforcement 31 and the rear seat cross beam 13 , and the second reinforcement 32 is connected to the third reinforcement 33 to be connected to the rear seat cross beam 13 through the third reinforcement 33 .

[0100] In some embodiments of the present application, the third reinforcement 33 is directly connected to the first reinforcement 31 and the rear seat cross beam 13 by welding. In some embodiments of the present application, the third reinforcement 33 is directly connected to the first reinforcement 31 by welding, and the third reinforcement 33 is indirectly connected to the rear seat cross beam 13 by a C ring 14. When the vehicle is subjected to external torque, the C ring 14 can resist the deformation of the torque together with the third reinforcement 33, thereby maintaining the stability and safety of the vehicle.

[0101] The second reinforcement 32 is connected to the third reinforcement 33, for example, the second reinforcement 32 is connected to the third reinforcement 33 by welding, or the second reinforcement 32 is connected to the third reinforcement 33 by riveting, so that the second reinforcement 32 is connected to the rear seat cross beam 13 through the third reinforcement 33, so that a continuous structure is formed among the C-pillar 15, the corner window lower cross beam 11, the second reinforcement 32, the third reinforcement 33, the C-ring 14 and the rear seat cross beam 13, so that the C-pillar 15, the corner window lower cross beam 11, the second reinforcement 32, the third reinforcement 33, the C-ring 14 and the rear seat cross beam 13 form a force transmission path, when the vehicle is twisted, the load of the C-pillar 15 and the corner window lower cross beam 11 can be transmitted to the rear seat cross beam 13 through the second reinforcement 32 and the third reinforcement 33, so as to improve the torsional stiffness of the rear wheel cover 2 area, reduce the risk of stress concentration in the rear wheel cover 2 area, and thus improve the fatigue durability of the rear wheel cover 2 area.

[0102] In some embodiments of the present invention, Figure 1 and Fig.12 As shown, the third reinforcement 33 may include: a first sub-reinforcement 331 and a second sub-reinforcement 332, the first sub-reinforcement 331 is connected to the first reinforcement 31, the second sub-reinforcement 332 is connected to the rear seat cross beam 13, the first sub-reinforcement 331 and the second sub-reinforcement 332 are connected, and an angle β1 is formed between the first sub-reinforcement 331 and the second sub-reinforcement 332, satisfying the relationship: 0°≤β1≤180°.

[0103] Wherein, as some embodiments of the present application, the first sub-reinforcement 331 and the second sub-reinforcement 332 are integrally formed. As some embodiments of the present application, the first sub-reinforcement 331 and the second sub-reinforcement 332 are welded to connect the first sub-reinforcement 331 and the second sub-reinforcement 332. The first sub-reinforcement 331 is connected to the first reinforcement 31, for example: the first sub-reinforcement 331 and the first reinforcement 31 can be welded, or the first sub-reinforcement 331 and the first reinforcement 31 can be riveted.

[0104] The second sub-reinforcement 332 is connected to the rear seat cross beam 13. For example, the second sub-reinforcement 332 is directly connected to the rear seat cross beam 13. The second sub-reinforcement 332 and the rear seat cross beam 13 can also be indirectly connected through the C ring 14. Such an arrangement can make the structural arrangement of the third reinforcement 33 reasonable. By connecting the third reinforcement 33 with the first reinforcement 31 and the second reinforcement 32, the integrity of the reinforcement structure 3 can be improved. The first reinforcement 31, the second reinforcement 32 and the third reinforcement 33 can also be connected, thereby forming a force transmission channel between each other, which is beneficial to improving the stiffness and strength of the reinforcement structure 3, thereby improving the torsional stiffness of the rear wheel cover 2 area.

[0105] The angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 satisfies the relationship: 0°≤β1≤180°, that is, the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 is greater than or equal to 0° and less than or equal to 180°. For example, the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 can be 0°, 120° or 180°, so that the angle β1 formed between the first sub-reinforcement 331 and the second sub-reinforcement 332 can be flexibly adjusted according to different vehicle models, so that the reinforcement structure 3 can adapt to different vehicle models, which is conducive to improving the layout flexibility and versatility of the reinforcement structure 3.

[0106] In some embodiments of the present invention, Figure 1 As shown, an angle β2 is formed between the second reinforcement member 32 and the second sub-reinforcement member 332 , satisfying the relationship: 0°≤β2≤90°.

For example, the angle β2 formed between the second reinforcement 32 and the second sub-reinforcement 332 can be 0°, 45° or 90°, and preferably β2=0°, β2=90°.

[0108] Specifically, when β2=90°, the second reinforcement 32 and the second sub-reinforcement 332 are arranged vertically. At this time, the third reinforcement 33 and the second reinforcement 32 form a "human" shape. Such an arrangement can make the structural arrangement of the third reinforcement 33 and the second reinforcement 32 reasonable, which is beneficial to the transfer of loads between the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, thereby further improving the torsional stiffness of the rear wheel cover 2 area.

[0109] When β2 = 0°, the first reinforcing member 31 and the third reinforcing member 33 are arranged to extend along the height direction of the vehicle. The first reinforcing member 31 is connected between the lower cross member 11 of the corner window and the rear longitudinal beam 12, and the third reinforcing member 33 is connected between the lower cross member 11 of the corner window and the C-ring 14, so that the third reinforcing member 33 and the rear longitudinal beam 12 are indirectly connected through the C-ring 14. The second reinforcing member 32 is arranged to extend along the length direction of the vehicle. One end of the second reinforcing member 32 is welded to the first reinforcing member 31, and the other end of the second reinforcing member 32 is welded to the C-ring 14, so that the first reinforcing member 31, the second reinforcing member 32, the third reinforcing member 33 and the C-ring 14 together form an "H" - shaped structure, thereby strengthening the structure 3 and the rear longitudinal beam 12, the lower cross member 11 of the corner window are connected to form a "day" - shaped reinforcing structure 3. Such an arrangement facilitates the layout of the reinforcing structure 3, is beneficial to reducing the assembly difficulty between the reinforcing structure 3 and the rear wheel housing 2, and further improves the assembly efficiency of the vehicle.

[0110] In some embodiments of the present invention, such as Figure 1 and Figure 3 shown, both the second reinforcing member 32 and the third reinforcing member 33 are located on the front side of the first reinforcing member 31. From the upper to the lower direction of the vehicle, the second reinforcing member 32 extends obliquely downward towards the first reinforcing member 31, and at least a part of the third reinforcing member 33 extends obliquely downward towards the front side of the first reinforcing member 31.

[0111] Among them, along the length direction of the vehicle, the second reinforcing member 32 is located on the front side of the first reinforcing member 31, and the third reinforcing member 33 is located on the front side of the first reinforcing member 31. Along the height direction of the vehicle, and from the upper to the lower direction of the vehicle, the second reinforcing member 32 extends obliquely downward towards the first reinforcing member 31, that is to say, the second reinforcing member 32 gradually extends towards the first reinforcing member 31 and gradually extends downward. Along the height direction of the vehicle, and from the upper to the lower direction of the vehicle, at least a part of the third reinforcing member 33 extends obliquely downward towards the front side of the first reinforcing member 31. As an example, a part of the third reinforcing member 33 extends obliquely downward towards the front side of the first reinforcing member 31. As another example, the whole of the third reinforcing member 33 extends obliquely downward towards the front side of the first reinforcing member 31. This application takes the first sub - reinforcing member 331 extending along the front - rear direction of the vehicle and the second sub - reinforcing member 332 extending obliquely downward towards the front side of the first reinforcing member 31 as an example for illustration. Such an arrangement can make the setting forms of the second reinforcing member 32 and the third reinforcing member 33 reasonable, is beneficial to improving the structural strength of the rear wheel housing 2, reducing the risk of the rear wheel housing 2 deforming under force, and improving the use reliability of the rear wheel housing 2.

In some embodiments of the present application, the third reinforcing member 33 and the rear seat cross member 13 can be indirectly connected through the C-ring 14. The present application takes the indirect connection between the third reinforcing member 33 and the rear seat cross member 13 through the C-ring 14 as an example for illustration. When the vehicle is subjected to an external torque, the C-ring 14 can resist the deformation of the torque together with the third reinforcing member 33, thereby maintaining the stability and safety of the vehicle.

[0114] By connecting the third reinforcing member 33 to the rear seat cross member 13 through the C-ring 14, a continuous structure can be formed among the C-pillar 15, the lower corner window cross member 11, the second reinforcing member 32, the third reinforcing member 33, the C-ring 14, and the rear seat cross member 13, so that a force transmission path is formed among the C-pillar 15, the lower corner window cross member 11, the second reinforcing member 32, the third reinforcing member 33, the C-ring 14, and the rear seat cross member 13. When the vehicle is twisted, the loads of the C-pillar 15 and the lower corner window cross member 11 can be transmitted to the rear seat cross member 13 through the second reinforcing member 32 and the third reinforcing member 33, so as to improve the torsional stiffness of the rear wheel housing 2 area, reduce the risk of stress concentration in the rear wheel housing 2 area, and thus improve the fatigue durability of the rear wheel housing 2 area.

The third reinforcing member 33 extends in the front-rear direction of the vehicle. One end of the second reinforcing member 32 is welded to the first reinforcing member 31, and the other end of the second reinforcing member 32 is welded to the C-ring 14, so that the first reinforcing member 31, the second reinforcing member 32, the third reinforcing member 33, and the C-ring 14 jointly form an "H" - shaped structure, thereby strengthening the "day" - shaped reinforcing structure 3 formed after the structure 3 is connected to the rear longitudinal beam 12 and the lower corner window cross member 11. Such a setting facilitates the arrangement of the reinforcing structure 3, is beneficial to reducing the assembly difficulty between the reinforcing structure 3 and the rear wheel housing 2, and further improves the assembly efficiency of the vehicle.

[0122] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the reinforcement structure 3 and the rear wheel housing 2 jointly define a first cavity 35 .

[0123] The reinforcing structure 3 and the rear wheel cover 2 may define a first cavity 35 together. For example, the reinforcing structure 3 may be formed with a groove structure, and the rear wheel cover 2 covers the open end of the groove structure, so that the reinforcing structure 3 and the rear wheel cover 2 define a first cavity 35 together. By defining the first cavity 35 together with the reinforcing structure 3 and the rear wheel cover 2, it is easy to form the first cavity 35, avoiding the reinforcing structure 3 or the rear wheel cover 2 forming a large first cavity 35 alone, thereby helping to reduce the manufacturing difficulty of the rear wheel cover assembly 200. It is also helpful to further improve the dynamic handling performance of the rear wheel cover assembly 200, and to further reduce the transmission of the noise of the vehicle to the passenger compartment, thereby improving the NVH performance of the vehicle.

[0124] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the first cavity 35 includes a plurality of first sub-cavities 351 , and any two adjacent first sub-cavities 351 are connected.

[0125] The first cavity 35 includes a plurality of first sub-cavities 351, for example, the first cavity 35 includes but is not limited to three or four first sub-cavities 351. As some embodiments of the present application, the first cavity 35 includes three first sub-cavities 351, and any two adjacent first sub-cavities 351 among the three first sub-cavities 351 are connected, which is beneficial to improve the force transmission efficiency of the load in the rear wheel cover 2 area. Specifically, the first reinforcement 31 and the rear wheel cover 2 jointly define a first sub-cavity 351, the second reinforcement 32 and the rear wheel cover 2 jointly define a first sub-cavity 351, and the third reinforcement 33 and the rear wheel cover 2 jointly define a first sub-cavity 351. Such an arrangement can make the number and position of the first sub-cavities 351 reasonably arranged, and multiple first sub-cavities 351 can be formed at any height of the rear wheel cover 2 area along the height direction of the vehicle, so that the rear wheel cover 2 area has no weak points along the height direction of the vehicle, thereby uniformly improving the torsional stiffness of the rear wheel cover 2 area.

[0126] In some embodiments of the present invention, Figure 6 As shown, the mounting seat 4 and the rear wheel cover 2 jointly define a second cavity 41 .

[0127] The mounting seat 4 and the rear wheel cover 2 may define a second cavity 41 together. For example, the mounting seat 4 may be formed with a groove structure, and the rear wheel cover 2 covers the open end of the groove structure, so that the mounting seat 4 and the rear wheel cover 2 define a second cavity 41 together. By defining the second cavity 41 together with the mounting seat 4 and the rear wheel cover 2, it is easy to form the second cavity 41, avoiding the mounting seat 4 or the rear wheel cover 2 forming a second cavity 41 with a large size alone, thereby reducing the manufacturing difficulty of the rear wheel cover assembly 200. It is also beneficial to further improve the rigidity, strength and durability of the mounting seat 4 area, and to improve the stability of the shock absorber support.

[0129] The second cavity 41 includes a plurality of second sub-cavities 411, for example, the second cavity 41 includes but is not limited to two, three or more second sub-cavities 411. As some embodiments of the present application, the second cavity 41 includes two second sub-cavities 411, and such a setting can make the number of second sub-cavities 411 reasonably set, and can further improve the rigidity, strength and durability of the mounting seat 4 area, which is beneficial to improving the stability of the shock absorber support, and is also beneficial to reducing the risk of increased production cost and assembly cost of the mounting seat 4 due to too many second sub-cavities 411.

[0130] In some embodiments of the present invention, Figure 6 As shown, the first cavity 35 and the second cavity 41 are partially offset along the width direction of the vehicle.

[0131] Among them, the first cavity 35 and the second cavity 41 are partially staggered along the width direction of the vehicle. For example, the second sub-cavity 411 can be arranged between two first sub-cavities 351 along the length direction of the vehicle, so that multiple first sub-cavities 351 and multiple second sub-cavities 411 are arranged along the length direction of the vehicle, thereby reducing the risk of sudden change in the structural stiffness of the rear wheel cover 2 area due to the disconnection of the first sub-cavity 351 along the length direction of the vehicle, which is beneficial to uniformly increase the torsional stiffness of the rear wheel cover 2 area along the length direction of the vehicle, thereby reducing the risk of deformation or even cracking of the rear wheel cover 2 area due to local stress concentration in the rear wheel cover 2 area along the length direction of the vehicle, which is beneficial to improving the reliability and service life of the vehicle.

[0142] The vehicle according to the embodiment of the present invention includes the rear wheel cover assembly 200 of the vehicle of the above embodiment. The rear wheel cover 2 and the C-ring 14 are the key load-bearing areas for vehicle torsion. Since the torsional stiffness level of the rear wheel cover assembly 200 is low, it will deteriorate the NVH comfort, dynamic handling stability and durability reliability of the vehicle. By designing the reinforcement structure 3, the risk of insufficient torsional stiffness of the vehicle body can be reduced, thereby improving the NVH and handling stability performance. When the vehicle is subjected to the ROC abuse condition (Reversing Over Curbside Impact Test), the insufficient stiffness and strength of the rear wheel cover 2 area are prone to strength damage failure, which is harmful to product reliability. The reinforcement structure 3 can reduce the risk of vehicle ROC condition fracture failure caused by insufficient stiffness and strength of the shock absorber support mounting point, thereby greatly improving the dynamic handling stability performance.

[0143] The reinforcement structure 3 of the rear wheel cover 2 can form multiple force transmission paths: the C-pillar 15, the lower cross beam 11 of the corner window, the second reinforcement 32, the third reinforcement 33, the C-ring 14 and the rear cross beam of the seat are connected to each other to form the first continuous force transmission path at the rear side of the vehicle, which plays a role in improving the torsional rigidity; the upper end of the first reinforcement 31 is connected to the lower cross beam 11 of the corner window, and the lower end is connected to the rear longitudinal beam 12. The lower cross beam 11 of the corner window, the first reinforcement 31 and the rear longitudinal beam 12 constitute the second continuous force transmission path at the rear side of the vehicle, which plays a role in strengthening the rigidity of the rear wheel cover 2; the inner plate 161 of the D-pillar joint and the inner plate 164 of the D-pillar constitute the third key force transmission path. The three force transmission paths can disperse the stress of the rear wheel cover 2, reduce the stress concentration level of the rear wheel cover 2, solve the problem of insufficient fatigue durability and easy cracking of the sheet metal structure and spot welding connection in the rear wheel cover 2 and the C-ring 14 area, and improve the fatigue durability and reliability of the vehicle.

[0144] Therefore, by setting the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, the second reinforcement 32 and the third reinforcement 33 are fixedly connected, the third reinforcement 33 and the first reinforcement 31 are fixedly connected, and an angle is formed between the second reinforcement 32 and the third reinforcement 33, a continuous force transmission path can be formed between the first reinforcement 31, the second reinforcement 32 and the third reinforcement 33, thereby effectively improving the torsional stiffness and strength of the rear wheel cover 2 area of ​​the vehicle, reducing the risk of deformation or even cracking in the rear wheel cover 2 area, thereby improving the reliability and safety of the vehicle.
