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

[0035] The vehicle body assembly 100 and the vehicle according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] like Figures 1-3 As shown, a vehicle body assembly 100 according to a first aspect 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 arch 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, and 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, such as Figure 1 and Figure 2 As shown, longitudinal beams 3 are fixedly connected to both sides of the rear floor 2. The fixing methods include, but are not limited to, welding and bolting. Furthermore, the body assembly 100 also includes two rear wheel arches 1, each of which is fixedly connected to a corresponding longitudinal beam 3. Specifically, the left rear wheel arch 1 is fixedly connected to the left longitudinal beam 3, and the right rear wheel arch 1 is fixedly connected to the right longitudinal beam 3.

[0038] Furthermore, each rear wheel arch 1 has a first reinforcing plate 4 and a third reinforcing plate 7 on its inner surface. This arrangement improves the strength of the rear wheel arch 1. It should be noted that the first reinforcing plate 4 is basically parallel to the height direction of the vehicle body, while 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 than the third reinforcing plate 7. Setting the width of the first reinforcing plate 4 to be greater than the width of the third reinforcing plate 7 is beneficial to improving the ability of the first reinforcing plate 4 to withstand impact loads, thereby further improving the strength of the rear wheel arch 1.

[0039] Furthermore, the rear floor 2 of the vehicle body is also provided with a second reinforcing plate 6, which improves the strength of the rear floor 2 itself. The body component 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. The fixing and installation methods include, but are not limited to, welding, bolt connection, etc. At the same time, the first connecting plates 5 are also connected between the corresponding first reinforcing plates 4 and second reinforcing plates 6. That is, the first connecting plate 5 on the left side is connected between the first reinforcing plate 4 and second reinforcing plate 6 on the left side, and the first connecting plate 5 on the right side is connected between the first reinforcing plate 4 and second reinforcing plate 6 on the right side. In this way, the first reinforcing plate 4 on the left side, the first connecting plate 5 on the left side, the second reinforcing plate 6, the first connecting plate 5 on the right side, and the first reinforcing plate 4 on the right side can be connected in series, which is beneficial to improving the connection strength between the rear wheel arch 1 and the rear floor 2, thereby improving the overall rigidity and strength of the rear of the vehicle body and meeting the strength and rigidity requirements of the rear of the large SUV body.

[0040] According to the embodiment of the present invention, the body assembly 100 improves the strength of the rear wheel arch 1 by providing a first reinforcing plate 4 and a third reinforcing plate 7 on the inner surface of the rear wheel arch 1. At the same time, a second reinforcing plate 6 is provided on the rear floor 2 and a first connecting plate 5 is provided on the longitudinal beam 3, so that the first connecting plate 5 connects the corresponding first reinforcing plate 4 and the second reinforcing plate 6, thereby connecting the first reinforcing plate 4 on the rear wheel arch 1 and the second reinforcing plate 6 on the rear floor 2 in series. While strengthening the strength of the rear wheel arch 1 and the rear floor 2, the connection strength between the rear wheel arch 1 and the rear floor 2 is improved, thereby improving the overall rigidity and strength of the rear of the vehicle body and meeting the strength and rigidity requirements after the vehicle is enlarged.

[0041] According to one embodiment of the present invention, such as Figures 1-3 As shown, the first reinforcing plate 4 has a first plate body 41 and a second plate body 42 connected together. 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 can be an integrally formed part composed of the first plate body 41 and the second plate body 42, or it can 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 described as an integrally formed part composed of the first plate body 41 and the second plate body 42. Specifically, as follows... Figure 3 As shown, both the first plate 41 and the second plate 42 are provided with a cavity structure. This configuration can improve the strength of the first reinforcing plate 4. Furthermore, both the first plate 41 and the second plate 42 are provided with flanges. The first plate 41 and the second plate 42 are fixedly connected to the inner surface of the rear wheel cover 1 through the flanges. The fixed connection methods include, but are not limited to, spot welding, bolt connection, etc.

[0043] Furthermore, the first plate 41 and the second plate 42 are located on different planes. The first plate 41 is curved to fit the rear wheel arch 1, and the second plate 42 extends along the height direction of the vehicle. This arrangement reduces the space occupied by the first plate 41, the second plate 42, and the rear wheel arch 1 during assembly, which helps to improve the interior space of the vehicle body. At the same time, the different planes of the first plate 41 and the second plate 42 can also enhance the strength of the first reinforcing plate 4, thereby further improving the strength of the rear wheel arch. Furthermore, the second plate 42 is connected between the first plate 41 and the corresponding first connecting plate 5, thereby connecting the rear wheel arch 1 and the first connecting plate 5 together through the first reinforcing plate 4. In turn, the first reinforcing plate 4 on the rear wheel arch 1 and the second reinforcing plate 6 on the rear floor 2 are connected in series through the first connecting plate 5, which helps to improve the connection strength between the rear wheel arch 1 and the rear floor 2. It should be noted that, referring to Figure 2 and Figure 3 As shown, the end of the first plate 41 away from the second plate 42 is also connected to the upper body of the vehicle body, which can optimize the force transmission route and effectively transfer the impact load of the upper support of the rear shock absorber spring and the longitudinal beam 3 of the rear floor 2 to the upper body. This helps to solve the problem of cracking of the lap weld points caused by excessive concentration of impact load and improves the rigidity of the whole vehicle.

[0044] According to one embodiment of the present invention, such as Figure 3 As shown, the first plate 41 and the second plate 42 form an angle, and along the height direction of the vehicle, the height of the angle is higher than the height of the corresponding rear seat of the vehicle. Specifically, as... 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. There is no specific limitation 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 seat of the vehicle. This setting can provide installation space for the rear seat and avoid interference between the first plate 41 and the second plate 42 and the rear seat.

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

[0046] Specifically, such as Figure 3As shown, the third reinforcing plate 7 has a cavity structure, which improves its own strength. Furthermore, the third reinforcing plate 7 has a flange, and the third reinforcing plate 7 is connected to the corresponding first reinforcing plate 4 through the flange. That is, 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. By setting the third reinforcing plate 7 in the rear wheel cover 1 and fixing it to the first reinforcing plate 4, the rigidity and strength of the rear wheel cover 1 are further improved. Moreover, the third reinforcing plate 7 is also indirectly connected to the second reinforcing plate 6 through the first reinforcing plate 4, which is conducive to further improving the overall rigidity and strength of the rear of the vehicle body. Furthermore, when the third reinforcing plate 7 is connected to the first reinforcing plate 4, a certain angle is formed. The angle can be in the range of 45°-75°. Optionally, the angle when the third reinforcing plate 7 is connected to the first reinforcing plate 4 can be set to 60°. This setting makes the force transmission between the third reinforcing plate 7 and the first reinforcing plate 4 more uniform, and avoids the third reinforcing plate 7 or the first reinforcing plate 4 from cracking due to deformation caused by force concentration because of excessive force transmission difference, thereby avoiding the failure of the rear wheel cover reinforcement.

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

[0048] Specifically, refer to Figures 1-3 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 of the vehicle. 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. Furthermore, the front end of the third reinforcing plate 7 is set at a lower height than the rear end of the third reinforcing plate 7. This arrangement allows the first reinforcing plate 4 and the third reinforcing plate 7 to form an inverted V-shape on the rear wheel arch 1. This not only helps to improve the overall rigidity and strength of the rear of the vehicle, but also increases the force transmission path through the third reinforcing plate 7. The impact loads of the upper support of the damping spring and the longitudinal beam 3 of the rear floor 2 can be transmitted to the upper body through the first reinforcing plate 4 and the second reinforcing plate 6, respectively. This further optimizes the force transmission path and helps to solve the problem of cracking of the lap weld points 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 integral molded part. For example, the third reinforcing plate 7 and the first reinforcing plate 4 can be set as an integral stamping or integral casting. No specific restrictions are made here. Therefore, setting the third reinforcing plate 7 and the first reinforcing plate 4 as an integral molded 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, such as Figure 1 and Figure 2 As shown, the second reinforcing plate 6 has a first side flange, which is connected to the rear floor 2; the first connecting plate 5 has a second side flange, which is located on the side of the first side flange away from the rear floor 2 and spaced apart from the first side flange.

[0051] Specifically, such as Figure 1 As shown, the second reinforcing plate 6 is fixedly connected to the rear floor 2 via the first side flange, and further, as... Figure 2 As shown, the first connecting plate 5 overlaps 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 spaced apart from the first side flange. That is to say, 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. This setting can reserve assembly space for the connection between the first connecting plate 5 and the longitudinal beam 3, so as to avoid interference when the first connecting plate 5 and the longitudinal beam 3 are assembled together.

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

[0053] Specifically, the body assembly 100 also includes a seat mounting crossbeam 8 and a second connecting plate 9. The seat mounting crossbeam 8 is fixedly mounted on the rear floor 2 and 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. The second connecting plates 9 are fixedly connected between the seat mounting crossbeam 8 and the corresponding rear wheel arch 1. For example, the second connecting plate 9 on the left is fixedly connected between the seat mounting crossbeam 8 and the left rear wheel arch 1, and the second connecting plate 9 on the right is fixedly connected between the seat mounting crossbeam 8 and the right rear wheel arch 1. This arrangement can connect the left rear wheel arch 1, the left second connecting plate 9, the seat mounting crossbeam 8, the right second connecting plate 9, and the right rear wheel arch 1 in series. This not only helps to improve the strength of the rear wheel arch 1 and the rear floor 2 themselves, but also helps to improve the connection strength between the rear wheel arch 1 and the rear floor 2, thereby improving the overall rigidity and strength of the rear of the vehicle body.

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

[0055] Specifically, the seat mounting beam 8 and the second reinforcing plate 6 are positioned opposite each other and spaced apart, with the seat mounting beam 8 located behind the second reinforcing plate 6. Furthermore, the second connecting plate 9 and the first connecting plate 5 are positioned opposite each other and spaced apart, with the second connecting plate 9 located behind the first connecting plate 5. In essence, the rear seats are assembled with the seat mounting beam 8 and the second reinforcing plate 6, allowing the rear seats to be mounted on the upper surfaces of the seat mounting beam 8 and the second reinforcing plate 6. Simultaneously, the seat mounting beam 8 and the second reinforcing plate 6 are fixedly connected to the rear wheel arch 1 via the first connecting plate 5 and the second connecting plate 9, respectively. This arrangement improves the installation strength of the rear seats, thus enhancing vehicle safety. It should be noted that when the vehicle is a 6-seater SUV, the third row of seats (the last row) and the second row of seats are arranged in a stepped configuration, ensuring a seat height difference and improving the visual experience for rear passengers.

[0056] According to one embodiment of the present invention, such as Figure 3 As shown, a groove 11 is formed on the inner surface of the rear wheel arch 1, which is recessed towards the interior of the rear wheel arch 1. The groove 11 is adapted to avoid obstructing the corresponding rear seats of the vehicle. Specifically, a groove 11 is also formed on the inner surface of the rear wheel arch 1, which is recessed towards the interior of the rear wheel arch 1. The partially recessed groove 11 has the function of reinforcing ribs, which can improve the local strength of the rear wheel arch 1. At the same time, the groove 11 is adapted to avoid obstructing the corresponding rear seats of the vehicle. For example, when the vehicle is a large SUV, the groove 11 is used to avoid obstructing the second-row seats to prevent interference during the installation of the second-row seats.

[0057] The vehicle according to a second aspect of the present invention includes the body assembly 100 of the vehicle in the first aspect.

[0058] According to an embodiment of the present invention, the vehicle is equipped with the aforementioned body assembly 100. By providing a first reinforcing plate 4 and a third reinforcing plate 7 on the inner surface of the rear wheel arch 1, the strength of the rear wheel arch 1 is improved. At the same time, a second reinforcing plate 6 is provided on the rear floor 2 and a first connecting plate 5 is provided on the longitudinal beam 3, such that the first connecting plate 5 connects the corresponding first reinforcing plate 4 and second reinforcing plate 6. This allows the first connecting plate 5 to connect the first reinforcing plate 4 on the rear wheel arch 1 and the second reinforcing plate 6 on the rear floor 2 in series. While strengthening the strength of the rear wheel arch 1 and the rear floor 2, the connection strength between the rear wheel arch 1 and the rear floor 2 is also improved, thereby improving the overall rigidity and strength of the rear of the vehicle body and meeting the strength and rigidity requirements after the vehicle is enlarged.
