DETAILED DESCRIPTION

[0025] In order to make the person skilled in the art better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0026] The ordinal numbers first, second, etc. used in the present text are used to distinguish different parts with the same name, and do not represent a specific order or primary and secondary relationship, etc.

[0027] The orientation words front, rear, left, right, top and bottom used in the present text are defined with the visual angle of a user sitting in the car as the reference, the direction close to the front of the car is front, the direction close to the rear of the car is rear, the direction close to the roof of the car is top, the direction close to the chassis of the car is bottom, the left hand side of the user facing the front of the car is left, and the right hand side is right. The car width direction is the left-right direction, and the car length direction is the front-rear direction; in addition, the transverse direction is a direction extending substantially along the car width direction, and the longitudinal direction is a direction extending substantially along the car length direction. It can be understood that the use of orientation words is only for the purpose of describing the technical scheme clearly and conveniently, and does not constitute a limitation on the protection scope.

[0028] After research, it is found that the rear quarter structure of the existing vehicle body is composed of multiple stamped plates connected by welding or bolt connection, etc. The number of parts of the rear quarter structure of the vehicle body is large, resulting in a large number of connection points and low integration. At the same time, because the number of parts is large, the correlation between the parts is strong during assembly, and it is extremely easy to cause assembly errors or deviations, thereby affecting the precision and assembly efficiency of the rear quarter structure of the vehicle body, and further affecting the performance of the rear quarter structure of the vehicle body. In view of this problem, the rear quarter structure of the vehicle body is optimized in the embodiments of the present application, and a vehicle body structural member and a rear quarter structure of a vehicle body including the same are provided.

[0029] For ease of understanding and concise description, the following text will explain the vehicle body structural components and the rear side panel structure that includes these components together, and the beneficial effects will not be discussed again.

[0030] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the rear side panel of the vehicle body provided in one embodiment of this application. Figure 2 for Figure 1 The exploded view of the rear side panel structure of the vehicle body is shown.

[0031] In this implementation plan, the rear side panel structure of the vehicle body includes two vehicle body structural components.

[0032] In this embodiment, the vehicle body structural components are integrally molded structures, including the C-pillar 11, D-pillar 12, longitudinal beam 13, rear wheel arch 14, and crossbeam structure. Specifically, the C-pillar 11, D-pillar 12, longitudinal beam 13, rear wheel arch 14, and crossbeam structure are integrally molded. The longitudinal beam 13 connects the top of the C-pillar 11 and the top of the D-pillar 12, and the crossbeam structure is connected to the longitudinal beam 13. It can be understood that the C-pillar 11, D-pillar 12, longitudinal beam 13, and rear wheel arch 14 of the vehicle body structural components are components on the same side of the vehicle.

[0033] For ease of description, the two aforementioned body structural components will be referred to as left body structural component 10A and right body structural component 10B, respectively. Left body structural component 10A and right body structural component 10B are arranged in the vehicle width direction. Figure 1 As shown, the left body structure component 10A is the module closer to the left side of the vehicle, and the right body structure component 10B is the module closer to the right side of the vehicle.

[0034] In the rear side structure of the vehicle body, the crossbeam structure of the left body structural component 10A is connected to the crossbeam structure of the right body structural component 10B.

[0035] By adopting the above solution, the C-pillar 11, D-pillar 12, longitudinal beam 13, rear wheel arch 14, and crossbeam structure located on the same side are integrated together to form a one-piece body structural component. The body structural components on both sides can be connected through their respective crossbeam structures to form the rear side panel structure of the body. In this way, the number of parts in the rear side panel structure is greatly reduced, and the number of connection points is reduced accordingly. The assembly process is simplified, effectively improving the integration of the rear side panel structure and improving manufacturing efficiency. At the same time, because the number of parts and connection points in the rear side panel structure is greatly reduced, the probability of assembly errors and deviations is reduced, which can improve the overall manufacturing precision of the rear side panel structure.

[0036] In an embodiment, the D-pillar 12 comprises a first pillar segment 121 extending substantially in the up-down direction and a second pillar segment 122 extending upward and forward from a top end of the first pillar segment 121, a front end of the second pillar segment 122 being connected to a rear end of a longitudinal beam 13 extending substantially in the vehicle length direction, and a front end of the longitudinal beam 13 being connected to a top end of the C-pillar 11.

[0037] In a specific implementation, the connection between the first pillar segment 121 and the second pillar segment 122 and the connection between the second pillar segment 122 and the longitudinal beam 13 are smoothly transitioned to provide a better streamline design for the rear side wall structure of the vehicle body.

[0038] The rear wheel cover 14 comprises a cover body 142 and a transition connecting plate 141 connected to the cover body 142, a front end of the transition connecting plate 141 extending to the area of the C-pillar 11 and a rear end of the transition connecting plate 141 extending to the area of the D-pillar 12, the transition connecting plate 141, the C-pillar 11, the second pillar segment 122 of the D-pillar 12 and the longitudinal beam 13 together enclosing a substantially triangular window structure.

[0039] In actual applications, the specific structures of the C-pillar 11, the rear wheel cover 14, the transition connecting plate 141, the D-pillar 12 and the longitudinal beam 13 can be set according to the design needs of the vehicle body and are not limited to the examples shown in the drawings.

[0040] In the present embodiment, the beam structure of the rear side wall structure of the vehicle body comprises a rear roof beam 15, the rear roof beam 15 comprising a first rear roof beam segment 151 and a second rear roof beam segment 152 arranged in the vehicle width direction, the beam structure of the left vehicle body structural member 10A comprising the first rear roof beam segment 151, the beam structure of the right vehicle body structural member 10B comprising the second rear roof beam segment 152, and the first rear roof beam segment 151 and the second rear roof beam segment 152 being connected to connect the two vehicle body structural members together.

[0041] In this way, the rear roof beam 15 is divided into two segments in the vehicle width direction, each segment being integrated on the corresponding vehicle body structural member, which can further reduce the number of parts and the number of connection points of the rear side wall structure of the vehicle body.

[0042] In a specific implementation, the connection between the first rear roof beam segment 151 and the second rear roof beam segment 152 of the rear roof beam 15 is located at a middle position of the rear roof beam 15, so that the left vehicle body structural member 10A and the right vehicle body structural member 10B are symmetrically arranged, which is beneficial to the processing of the two vehicle body structural members.

[0043] In this embodiment, the crossbeam structure of the rear side panel of the vehicle body also includes a C-pillar crossbeam 16. The C-pillar crossbeam 16 includes a first C-pillar crossbeam segment 161 and a second C-pillar crossbeam segment 162 arranged along the vehicle width direction. The crossbeam structure of the left body structural component 10A includes the first C-pillar crossbeam segment 161, and the crossbeam structure of the right body structural component 10B includes the second C-pillar crossbeam segment 162. The first C-pillar crossbeam segment 161 and the second C-pillar crossbeam segment 162 are connected.

[0044] In this way, the C-pillar crossbeam 16 is divided into two sections in the vehicle width direction, and each section is integrally formed with the corresponding side body structure component, which can further reduce the number of parts and connection points of the rear side structure of the vehicle body.

[0045] In the specific implementation, the connection between the first C-pillar upper crossbeam segment 161 and the second C-pillar upper crossbeam segment 162 of the C-pillar upper crossbeam 16 is located in the middle of the C-pillar upper crossbeam 16. In this way, the left body structural component 10A and the right body structural component 10B are symmetrically arranged, which is beneficial to the processing of the body structural components.

[0046] In the illustrated example, the end of the rear crossbeam 15 of the roof is connected to the longitudinal beam 13 and the D-pillar 12 at the connection point. The upper crossbeam 16 of the C-pillar is located in front of the rear crossbeam 15 of the roof. The end of the upper crossbeam 16 of the C-pillar is connected to the longitudinal beam 13 and roughly corresponds to the position of the C-pillar 11. That is, one end of the first rear roof crossbeam section 151 is connected to the D-pillar 12 and the longitudinal beam 13 of the left body structural component 10A, and one end of the second rear roof crossbeam section 152 is connected to the D-pillar 12 and the longitudinal beam 13 of the right body structural component 10B, and the other end of the first rear roof crossbeam section 151 is connected to the other end of the second rear roof crossbeam section 152; one end of the first C-pillar upper crossbeam section 161 is connected to the longitudinal beam 13 of the left body structural component 10A and is aligned with the C-pillar 11 of the left body structural component 10A, one end of the second C-pillar upper crossbeam section 162 is connected to the longitudinal beam 13 of the right body structural component 10B and is aligned with the C-pillar 11 of the right body structural component 10B, and the other end of the first C-pillar upper crossbeam section 161 is connected to the other end of the second C-pillar upper crossbeam section 162.

[0047] In the illustrated example, the rear roof crossbeam 15 and the upper C-pillar crossbeam 16 are both divided into two sections, which are integrally formed with the left body structural component 10A and the right body structural component 10B, respectively. With this configuration, the rear side panel structure of the vehicle body is divided into two body structural components, namely, the rear side panel structure of the vehicle body has only two parts. During assembly, it is only necessary to connect the first rear roof crossbeam section 151 and the second rear roof crossbeam section 152, and the first upper C-pillar crossbeam section 161 and the second upper C-pillar crossbeam section 162. Thus, the rear side panel structure of the vehicle body illustrated has only two connection points during assembly. Compared with the traditional rear side panel structure of the vehicle body, which includes dozens of parts, the rear side panel structure of the vehicle body illustrated in the figure has a higher degree of integration, a simpler assembly process, and can further improve manufacturing efficiency.

[0048] Please refer to this as well. Figure 3 and Figure 4 , Figure 3 for Figure 1 A magnified view of a portion of the connection between the first and second sections of the rear crossbeam of the vehicle's roof. Figure 4 for Figure 1 A magnified view of the connection between the first and second crossbeam sections of the C-column.

[0049] like Figure 3 As shown, the first rear crossbeam section 151 and the second rear crossbeam section 152 of the roof can be fixedly connected using SPR (Self-Piercing Rivet) rivets 20, such as... Figure 4 As shown, the first C-pillar upper crossbeam segment 161 and the second C-pillar upper crossbeam segment 162 can also be fixedly connected using SPR rivets 20.

[0050] In other embodiments, the first rear roof beam section 151 and the second rear roof beam section 152 can be fixed by welding, or by using other rivets or bolts to achieve a fixed connection; the first C-pillar upper beam section 161 and the second C-pillar upper beam section 162 can also be fixed by welding, or by using other rivets or bolts to achieve a fixed connection.

[0051] In this implementation plan, the rear crossbeam section of the roof or the upper crossbeam section of the C-pillar of the vehicle body structural component is an integral structure with the vehicle body structural component. Under the same performance requirements, a smaller cavity size can be achieved, which is beneficial to improving space utilization.

[0052] In some other embodiments, the first rear roof crossbeam section 151 may be independent of the left body structure 10A, or the second rear roof crossbeam section 152 may be independent of the right body structure 10B. During assembly, the end of the first rear roof crossbeam section 151 is fixed to the left body structure 10A by welding or fastener connection, and the end of the second rear roof crossbeam section 152 is fixed to the right body structure 10B by welding or fastener connection.

[0053] In some other embodiments, the first C-pillar upper crossbeam segment 161 can be independent of the left vehicle body structure 10A, or the second C-pillar upper crossbeam segment 162 can be independent of the right vehicle body structure 10B. During assembly, the end of the first C-pillar upper crossbeam segment 161 is fixed to the left vehicle body structure 10A by welding or fastener connection, and the end of the second C-pillar upper crossbeam segment 162 is fixed to the right vehicle body structure 10B by welding or fastener connection.

[0054] In this embodiment, both the first rear crossbeam section 151 and the second rear crossbeam section 152 of the roof are provided with tailgate mounting points 17 to facilitate the installation of the vehicle's tailgate, i.e., the tailgate of the trunk.

[0055] In practice, the tailgate mounting point 17 can be a boss that protrudes upward from the surface of the rear crossbeam 15 on the roof. This boss can have pre-drilled mounting holes and other structures for installing the tailgate. The structure of the boss helps to improve the structural strength of the location of the tailgate mounting point 17.

[0056] In this embodiment, the D-pillar 12 of the vehicle body structure is provided with a strut mounting point 18, that is, the D-pillar 12 is provided with a mounting position for mounting a strut. The strut is used to support the tailgate when it is opened. Depending on the actual application requirements, the strut can be a hydraulic strut or an electrically powered strut.

[0057] In practice, the strut mounting point 18 can be a boss protruding outward from the surface of the D-pillar 12. This boss can have pre-drilled mounting holes and other structures for mounting the strut. Here, "outward" refers to the side furthest from the vehicle's interior space. The boss's structure helps improve the structural strength of the location of the strut mounting point 18.

[0058] In this embodiment, the body structural components also include reinforcing ribs 19. At least one of the C-pillar 11, D-pillar 12, longitudinal beam 13, rear wheel arch 14, and crossbeam structure is provided with reinforcing ribs 19. This can improve the structural strength of the body structural components, thereby improving the structural strength of the rear side panel structure of the body, which is beneficial to improving the torsional stiffness of the whole vehicle and also to improving the vehicle's handling performance.

[0059] In practice, the C-pillar 11, D-pillar 12, longitudinal beam 13, rear wheel arch 14, and crossbeam structure are all equipped with reinforcing ribs 19. The crossbeam structure includes the rear crossbeam section of the roof and the upper crossbeam section of the C-pillar.

[0060] In practice, the reinforcing rib 19 is integrally formed with the structure of the corresponding area. Taking the illustrated example, the rear side structure of the vehicle body includes a left body structural component 10A and a right body structural component 10B. Each side of the body structural component is an integrally formed structure, and each side of the body structural component also has an integrally formed reinforcing rib 19.

[0061] In a specific implementation, the reinforcing rib 19 includes a first reinforcing rib 191 and a second reinforcing rib 192. The extension direction of the first reinforcing rib 191 intersects with the extension direction of the second reinforcing rib 192, that is, the first reinforcing rib 191 and the second reinforcing rib 192 are arranged alternately, which is beneficial to improving the structural strength of the rear side panel structure of the vehicle body.

[0062] In one implementation example, combined Figure 1 and Figure 2 The rear wheel arch 14 has a transition connecting plate 141 with a first reinforcing rib 191 extending generally in the front-rear direction and a second reinforcing rib 192 extending generally in the vertical direction. The rear wheel arch 14 has a cover body 142 with a reinforcing rib 19 extending generally in the left-right direction. The D-pillar 12 has a first reinforcing rib 191 extending generally in the left-right direction and a second reinforcing rib 192 extending generally in the front-rear or vertical direction. The first reinforcing rib 191 of the D-pillar 12 can also be integrated with the reinforcing rib 19 on the cover body 142. The longitudinal beam 13 has a first reinforcing rib extending generally in the left-right direction. A reinforcing rib 191 and a second reinforcing rib 192 extending generally in the front-rear direction are provided on the first rear crossbeam section 151 and the second rear crossbeam section 152 of the roof. The first reinforcing rib 191 and the second reinforcing rib 192 extending generally in the left-right direction are provided on the first rear crossbeam section 161 and the second rear crossbeam section 162 of the C-pillar. The first reinforcing rib 191 and the second reinforcing rib 192 extending generally in the front-rear direction are provided on the first upper crossbeam section 161 and the second upper ... are provided on the second rear crossbeam section 162 of the C-pillar.

[0063] Among them, the second reinforcing rib 192 of the D-pillar 12 and the longitudinal beam 13 can also be considered to be set roughly along the force transmission direction of the vehicle body. The first reinforcing rib 191 and the second reinforcing rib 192 are arranged perpendicularly, which is beneficial to improving the stress performance of the vehicle body.

[0064] In the illustrated example, the first reinforcing rib 191 and the second reinforcing rib 192 are basically arranged in a cross shape. In other embodiments, the extension direction of the first reinforcing rib 191 or the extension direction of the second reinforcing rib 192 can be set according to the application requirements.

[0065] In this implementation plan, the vehicle body structural components are integral die-cast parts, meaning that the vehicle body structural components are integrally formed by die casting. The die casting process has a high material utilization rate and production efficiency, which helps to save costs.

[0066] Furthermore, using die casting facilitates control over the thickness of various components, including the thickness of the reinforcing rib 19, and also allows for control over the placement and density of the reinforcing rib 19, meeting higher requirements for collision resistance, rigidity, and NVH (noise, vibration, and harshness), while also reducing redundant parts. For example, the material thickness at the tailgate mounting point 17 and the strut mounting point 18 can be relatively large, while the material thickness at the rear wheel arch cover body 142 can be relatively small. For instance, the maximum material thickness at the tailgate mounting point 17 and the strut mounting point 18 can be 6mm, while the material thickness at other locations of the body structural components, excluding the tailgate mounting point 17 and the strut mounting point 18, can be 2-4mm.

[0067] In this implementation plan, the rear side panel structure of the vehicle body is made of aluminum alloy. This reduces the weight of the rear side panel structure, which is beneficial for the lightweight design of the vehicle body.

[0068] This application also provides a vehicle that includes the rear side panel structure described in the foregoing embodiments, and has the same technical effects as the aforementioned rear side panel structure, which will not be repeated here.

[0069] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
