[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0035] A vehicle body assembly 100 and a vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 3 As shown, the vehicle body assembly 100 according to the first embodiment of the present invention includes: a first reinforcing plate 4, a first connecting plate 5, a second reinforcing plate 6 and a third reinforcing plate 7. The first reinforcing plate 4 and the third reinforcing plate 7 are both fixed to the inner surface of the rear wheel cover 1 of the vehicle, and the width of the first reinforcing plate 4 is greater than the width of the third reinforcing plate 7. The second reinforcing plate 6 is fixed to the rear floor 2 of the vehicle, the first connecting plate 5 is fixed to the longitudinal beam 3 of the vehicle, and the first connecting plate 5 is connected between the corresponding first reinforcing plate 4 and the second reinforcing plate 6.

[0037] Specifically, Figure 1 and Figure 2 As shown, both sides of the rear floor 2 are fixedly connected with longitudinal beams 3, and the fixing connection methods include but are not limited to welding, bolt connection, etc. Further, the body assembly 100 also includes two rear wheel covers 1, each of which is fixedly connected to the corresponding longitudinal beam 3, specifically, the left rear wheel cover 1 is fixedly connected to the left longitudinal beam 3, and the right rear wheel cover 1 is fixedly connected to the right longitudinal beam 3.

[0038] Furthermore, the inner surface of each rear wheel cover 1 is provided with a first reinforcing plate 4 and a third reinforcing plate 7. With such arrangement, the self-strength of the rear wheel cover 1 is improved by means of the first reinforcing plate 4 and the third reinforcing plate 7. It should be noted that the first reinforcing plate 4 is basically parallel to the height direction of the vehicle body, and the third reinforcing plate 7 has a certain angle with the height direction of the vehicle body. Therefore, the first reinforcing plate 4 will bear a greater impact load force than the third reinforcing plate 7. Setting the width of the first reinforcing plate 4 to be larger than the width of the third reinforcing plate 7 is beneficial to improving the ability of the first reinforcing plate 4 to withstand impact load force, thereby helping to further improve the self-strength of the rear wheel cover 1.

[0039] Furthermore, the rear floor 2 of the vehicle body is also provided with a second reinforcing plate 6, which improves the self-strength of the rear floor 2. The vehicle body assembly 100 is also provided with two first connecting plates 5. Specifically, the two first connecting plates 5 are respectively fixedly installed on the longitudinal beams 3 on the left and right sides, and the fixing installation methods include but are not limited to welding, bolt connection, etc. At the same time, the first connecting plate 5 is also connected between the corresponding first reinforcing plate 4 and the second reinforcing plate 6, that is, the first connecting plate 5 on the left is connected between the first reinforcing plate 4 and the second reinforcing plate 6 on the left, and the first connecting plate 5 on the right is connected between the first reinforcing plate 4 and the second reinforcing plate 6 on the right. In this way, the first reinforcing plate 4 on the left, the first connecting plate 5 on the left, the second reinforcing plate 6, the first connecting plate 5 on the right and the first reinforcing plate 4 on the right can be connected in series, which is beneficial to improving the connection strength between the rear wheel cover 1 and the rear floor 2, and then the overall stiffness and strength of the rear part of the vehicle body can be improved, meeting the strength and stiffness requirements of the rear part of the large SUV body.

[0040] According to the vehicle body assembly 100 of the embodiment of the present invention, the self-strength of the rear wheel cover 1 is improved by arranging the first reinforcing plate 4 and the third reinforcing plate 7 on the inner surface of the rear wheel cover 1. At the same time, the second reinforcing plate 6 is arranged on the rear floor 2 and the first connecting plate 5 is arranged on the longitudinal beam 3, so that the first connecting plate 5 is connected between the corresponding first reinforcing plate 4 and the second reinforcing plate 6, so that the first connecting plate 5 connects the first reinforcing plate 4 on the rear wheel cover 1 and the second reinforcing plate 6 on the rear floor 2 in series, and while strengthening the self-strength of the rear wheel cover 1 and the rear floor 2, the connection strength between the rear wheel cover 1 and the rear floor 2 is improved, thereby improving the overall stiffness and strength of the rear part of the vehicle body, and meeting the strength and stiffness requirements of the large-scale vehicle.

[0041] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the first reinforcing plate 4 has a connected first plate body 41 and a second plate body 42, the first plate body 41 and the second plate body 42 are located in different planes, the second plate body 42 is connected between the first plate body 41 and the corresponding first connecting plate 5, and the second plate body 42 extends along the height direction of the vehicle.

[0042] Specifically, the first reinforcing plate 4 is composed of a first plate body 41 and a second plate body 42. Optionally, the first reinforcing plate 4 may be an integrally formed part composed of the first plate body 41 and the second plate body 42, or may be a detachable part composed of the first plate body 41 and the second plate body 42. In some embodiments of the present invention, the first reinforcing plate 4 is taken as an example to be an integrally formed part composed of the first plate body 41 and the second plate body 42. Specifically, Figure 3 As shown, the first plate body 41 and the second plate body 42 are both provided with a cavity structure. Such a configuration can improve the inherent strength of the first reinforcing plate 4. Furthermore, the first plate body 41 and the second plate body 42 are both provided with a flange, and the first plate body 41 and the second plate body 42 are fixedly connected to the inner surface of the rear wheel cover 1 through the flange, and the fixed connection method includes but is not limited to spot welding, bolt connection, etc.

[0043] Furthermore, the first plate body 41 and the second plate body 42 are located in different planes, wherein the first plate body 41 is arranged in a curved shape so as to fit with the rear wheel cover 1, and the second plate body 42 extends along the height direction of the vehicle. Such an arrangement reduces the space occupied by the first plate body 41, the second plate body 42 and the rear wheel cover 1 when assembled, which is beneficial to improving the interior space of the vehicle body. At the same time, the first plate body 41 and the second plate body 42 in different planes can also enhance the self-strength of the first reinforcing plate 4, which is beneficial to further improve the strength of the rear wheel cover. Furthermore, the second plate body 42 is connected between the first plate body 41 and the corresponding first connecting plate 5, so that the rear wheel cover 1 and the first connecting plate 5 are connected together through the first reinforcing plate 4, and then the first reinforcing plate 4 on the rear wheel cover 1 and the second reinforcing plate 6 of the rear floor 2 are connected in series through the first connecting plate 5, which is beneficial to improving the connection strength between the rear wheel cover 1 and the rear floor 2. It should be noted that, referring to Figure 2 and Figure 3 As shown, one end of the first plate 41 away from the second plate 42 is also connected to the upper body of the vehicle body, so as to optimize the force transmission route, so that the impact load of the rear shock absorber spring upper support and the rear floor 2 longitudinal beam 3 is effectively transmitted to the upper body, which is conducive to solving the problem of cracking of the lap welds caused by excessive concentration of impact loads and improves the rigidity of the entire vehicle.

[0044] According to one embodiment of the present invention, Figure 3 As shown, an angle is formed between the first plate 41 and the second plate 42, and along the height direction of the vehicle, the height of the angle is higher than the height of the corresponding rear seats of the vehicle. Figure 3 As shown, there is a certain angle between the first plate 41 and the second plate 42. The size of the angle is set according to the specific shape of the rear wheel cover 1. No specific restriction is made here. It should be noted that along the height direction of the vehicle, the height of the angle position is higher than the height of the corresponding rear seats of the vehicle. Such a setting can provide installation space for the rear seats and avoid interference between the first plate 41 and the second plate 42 and the rear seats.

[0045] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the third reinforcing plate 7 is connected to the corresponding first reinforcing plate 4 and forms an angle.

[0046] Specifically, Figure 3As shown, the third reinforcing plate 7 is provided with a cavity structure, which improves the self strength of the third reinforcing plate 7. Furthermore, the third reinforcing plate 7 is provided with a flange, and the third reinforcing plate 7 is connected to the corresponding first reinforcing plate 4 through the flange. That is to say, the third reinforcing plate 7 in the left rear wheel cover 1 is connected to the corresponding first reinforcing plate 4, and the third reinforcing plate 7 in the right rear wheel cover 1 is connected to the corresponding first reinforcing plate 4. In this way, by arranging the third reinforcing plate 7 in the rear wheel cover 1 and fixing it with the first reinforcing plate 4, the rigidity and strength of the rear wheel cover 1 are further improved, and the third reinforcing plate 7 is also indirectly connected to the second reinforcing plate 6 through the first reinforcing plate 4, which is beneficial to further improve the overall rigidity and strength of the rear part of the vehicle body. Furthermore, a certain angle is formed when the third reinforcing plate 7 is connected to the first reinforcing plate 4, and the range of the angle can be 45°-75°. Optionally, the angle when the third reinforcing plate 7 is connected to the first reinforcing plate 4 can be set to 60°. With this setting, the force transmission between the third reinforcing plate 7 and the first reinforcing plate 4 is more uniform, avoiding the third reinforcing plate 7 or the first reinforcing plate 4 from deforming and cracking due to concentrated force due to a large difference in force transmission, thereby avoiding the failure of reinforcement of the rear wheel cover.

[0047] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the third reinforcing plate 7 extends along the length direction of the vehicle and is located at the rear side of the first reinforcing plate 4 , and the front end of the third reinforcing plate 7 is set at a height lower than the rear end of the third reinforcing plate 7 .

[0048] Specifically, refer to Figure 1-Figure 3 As shown, the third reinforcing plate 7 is fixedly connected to the rear side of the first reinforcing plate 4, and the third reinforcing plate 7 extends along the length direction of the vehicle, wherein the front end of the third reinforcing plate 7 is fixedly connected to the first reinforcing plate 4, and the rear end of the third reinforcing plate 7 is connected to the upper body of the vehicle body. Further, the front end of the third reinforcing plate 7 is set at a height lower than the rear end of the third reinforcing plate 7. With this arrangement, the first reinforcing plate 4 and the third reinforcing plate 7 form an inverted herringbone shape on the rear wheel cover 1, which is not only beneficial to improving the overall rigidity and strength of the rear part of the vehicle body, but also increases the force transmission route through the third reinforcing plate 7, and can transmit the impact load of the upper support of the shock absorbing spring and the longitudinal beam 3 of the rear floor 2 to the upper body through the first reinforcing plate 4 and the second reinforcing plate 6 respectively, further optimizing the force transmission path, which is beneficial to solving the problem of cracking of lap welds caused by excessive concentration of impact loads.

[0049] It should be noted that the third reinforcing plate 7 and the corresponding first reinforcing plate 4 can be set as an integrally formed part. For example, the third reinforcing plate 7 and the first reinforcing plate 4 can be set as an integrally stamped part, or set as an integrally cast part. No specific restrictions are made here. Therefore, setting the third reinforcing plate 7 and the first reinforcing plate 4 as an integrally formed part can reduce the number of parts, which is beneficial to reducing assembly time and production costs.

[0050] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the second reinforcing plate 6 has a first side flange connected to the rear floor 2; the first connecting plate 5 has a second side flange located on a side of the first side flange away from the rear floor 2 and spaced apart from the first side flange.

[0051] Specifically, Figure 1 As shown, the second reinforcing plate 6 is fixedly connected to the rear floor 2 through the first side flange. Figure 2 As shown, the first connecting plate 5 is overlapped on the second reinforcing plate 6, and the second side flange of the first connecting plate 5 is located on the side of the first side flange away from the rear floor 2 and is separated from the first side flange, that is, there is a certain height difference between the second side flange of the first connecting plate 5 and the first side flange of the second reinforcing plate 6, that is, the height of the second side flange of the first connecting plate 5 is higher than the height of the first side flange of the second reinforcing plate 6. In this way, an assembly space can be reserved for the connection between the first connecting plate 5 and the longitudinal beam 3 to avoid interference when the first connecting plate 5 and the longitudinal beam 3 are assembled.

[0052] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, it also includes: a seat mounting cross beam 8 and a second connecting plate 9, the rear floor 2 is provided with a seat mounting cross beam 8, the longitudinal beam 3 is fixed with a second connecting plate 9, and the second connecting plate 9 is connected between the seat mounting cross beam 8 and the corresponding rear wheel cover 1.

[0053] Specifically, the body component 100 also includes a seat mounting beam 8 and a second connecting plate 9, wherein the seat mounting beam 8 is fixedly mounted on the rear floor 2, and the seat mounting beam 8 is used to mount the rear seats. Furthermore, the longitudinal beams 3 on both sides of the rear floor 2 are provided with second connecting plates 9, and the second connecting plates 9 are fixedly connected between the seat mounting beam 8 and the corresponding rear wheel cover 1. For example, the second connecting plate 9 on the left side is fixedly connected between the seat mounting beam 8 and the rear wheel cover 1 on the left side, and the second connecting plate 9 on the right side is fixedly connected between the seat mounting beam 8 and the rear wheel cover 1 on the right side. In this way, the rear wheel cover 1 on the left side, the second connecting plate 9 on the left side, the seat mounting beam 8, the second connecting plate 9 on the right side and the rear wheel cover 1 on the right side can be connected in series, which is not only beneficial to improving the self-strength of the rear wheel cover 1 and the rear floor 2, but also beneficial to improving the connection strength between the rear wheel cover 1 and the rear floor 2, thereby improving the overall stiffness and strength of the rear part of the body.

[0054] According to one embodiment of the present invention, Figure 1 and Figure 2As shown, the seat mounting cross beam 8 is opposite to the second reinforcing plate 6 and is located at the rear side of the second reinforcing plate 6 ; the second connecting plate 9 is opposite to the first connecting plate 5 and is located at the rear side of the first connecting plate 5 .

[0055] Specifically, the seat mounting crossbeam 8 is arranged opposite to and spaced from the second reinforcing plate 6, wherein the seat mounting crossbeam 8 is located at the rear side of the second reinforcing plate 6, further, the second connecting plate 9 is arranged opposite to and spaced from the first connecting plate 5, wherein the second connecting plate 9 is located at the rear side of the first connecting plate 5, specifically, the rear row seats are assembled with the seat mounting crossbeam 8 and the second reinforcing plate 6, so that the rear row seats are mounted on the upper surface of the seat mounting crossbeam 8 and the second reinforcing plate 6, and at the same time, the seat mounting crossbeam 8 and the second reinforcing plate 6 are fixedly connected to the rear wheel cover 1 through the first connecting plate 5 and the second connecting plate 9, respectively, so that the installation strength of the rear row seats is improved, which is conducive to improving the safety performance of the vehicle. It should be noted that when the vehicle is a 6-seat SUV, the third row of seats (the last row of seats) and the second row of seats are arranged in a stepped manner, thereby ensuring the seat height difference and improving the visual experience of the rear passengers.

[0056] According to one embodiment of the present invention, Figure 3 As shown, the inner surface of the rear wheel cover 1 is formed with a groove 11 that is sunken toward the rear wheel cover 1, and the groove 11 is suitable for avoiding the corresponding rear seats of the vehicle. Specifically, the inner surface of the rear wheel cover 1 is also formed with a groove 11 that is sunken toward the rear wheel cover 1, and the partially sunken groove 11 has the function of reinforcing ribs, which can improve the local strength of the rear wheel cover 1. At the same time, the groove 11 is suitable for avoiding the corresponding rear seats of the vehicle. For example, when the vehicle is a large SUV, the groove 11 is used to avoid the second row of seats to avoid interference during the installation of the second row of seats.
