[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0034] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs. The "first", "second" and similar words used in one or more embodiments of this specification do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] To facilitate understanding of the side panel rear section assembly provided in the embodiment of the present application, its application scenario is first described. The side panel rear section assembly provided in the embodiment of the present application can be applied to vehicles, in particular to automobiles, and specifically can be used as a component of the automobile body. The side panel rear section assembly is an important component of the vehicle body structure, and usually includes the C-pillar, D-pillar, rear roof crossbeam, wheel arches and other parts. The traditional production method of the side panel rear section assembly is to divide the side panel rear section assembly into several parts and manufacture them separately during the design stage, and then produce each part separately by stamping steel, stamping aluminum, and steel-aluminum mixed methods, and then weld and assemble the parts to form an overall side panel rear section assembly.

[0036] However, the stamping-welding solution in the prior art has certain disadvantages. For example, during the design process, not only the structural strength requirements of each part itself must be met, but also the final assembly and coordination of each part and the structural strength of the overall side panel rear section assembly after assembly must be considered, which makes the design process of the side panel rear section assembly complicated. Another example is that during the production process, since each part needs to be stamped and produced separately, the production process has many steps and molds, which will inevitably lengthen the entire process. And for the assembly, the more parts there are, the more difficult it is to control the overall dimensional accuracy, which undoubtedly requires a greater investment cost.

[0037] To this end, the present application provides a side panel rear section assembly, which is designed to be integrally formed with multiple parts of the side panel rear section assembly, and each part is designed with a different structure to meet the structural strength requirements, so as to improve the problems of the long process flow and large number of parts of the side panel rear section assembly in the prior art. The side panel rear section assembly provided by the embodiment of the present application is specifically described below in conjunction with the accompanying drawings.

[0038] refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the overall side panel rear section assembly in the embodiment of the present application. Figure 1 A coordinate system is established in the subsequent figures, in which the X-axis direction is the width direction of the vehicle body, the Y-axis direction is the length direction of the vehicle body, and the Z-axis direction is the height direction of the vehicle body. It is worth noting that in the following description, in the length direction of the vehicle body, the side where the front of the vehicle is located is the front, and the side where the rear of the vehicle is located is the rear.

[0039] The side rear section assembly provided in the present application includes an integrally formed C-pillar portion 1, a D-pillar portion 2, a rear top cross beam portion 3 and a wheel housing portion 4. The C-pillar portion 1 and the D-pillar portion 2 are both used to be arranged on the side of the vehicle body in the width direction of the vehicle body. The C-pillar portion 1 is located at the side and rear of the rear seats of the vehicle and serves as the main supporting structure of the C-pillar of the vehicle; along the length direction of the vehicle body, the D-pillar portion 2 is located behind the C-pillar portion 1, and the D-pillar portion 2 mainly forms the D-pillar of the vehicle. Generally speaking, there is a space between the C-pillar portion 1 and the D-pillar portion 2 to form a rear triangular window of the vehicle. The rear top cross beam portion 3 is extended along the width direction of the vehicle body, and is specifically arranged at the rear end of the side rear section assembly along the height direction of the vehicle body; as a component of the rear top cross beam of the vehicle, the rear top cross beam portion 3 extends from the side of the vehicle body to the middle of the vehicle body along the width direction of the vehicle body. When the whole vehicle is specifically assembled, the rear top cross beam of the side rear section assembly located on one side can be combined with the rear top cross beam of the side rear section assembly located on the other side to form the rear top cross beam of the vehicle body.

[0040] The wheel cover portion 4 is also located at a position set on the side of the vehicle body, and the wheel cover portion 4 can specifically serve as the main supporting part of the vehicle wheel cover. The wheel cover is a key part in the vehicle body, and its main function is to protect the wheel hub and tire. In the side rear section assembly of the embodiment of the present application, the wheel cover portion 4 is mainly used to constitute the rear wheel cover of the vehicle body. Specifically, the wheel cover portion 4 is located below the D-pillar portion 2 in the height direction of the vehicle body, and the wheel cover portion 4 is integrally connected to the D-pillar portion 2.

[0041] At least two connecting reinforcement ribs 5 are arranged at the connection between the wheel arch portion 4 and the D-pillar portion 2. These connecting reinforcement ribs 5 are arranged at intervals along the length direction of the vehicle body, and each reinforcement rib extends along the height direction of the vehicle body. Specifically, for any one of the connecting reinforcement ribs 5, each reinforcement rib extends from the D-pillar portion 2 to the wheel arch portion 4 along the height direction of the vehicle body. That is, each connecting reinforcement rib 5 is fixed to the D-pillar portion 2 and the wheel arch portion 4 at the same time, and each connecting reinforcement rib 5 can improve the connection strength between the wheel arch portion 4 and the D-pillar portion 2, especially the connection strength between the wheel arch portion 4 and the D-pillar portion 2 when subjected to force along the width direction of the vehicle body. When the connecting reinforcement ribs 5 are specifically arranged, the number of connecting reinforcement ribs can be two, three, four, etc. The specific number of connecting reinforcement ribs 5 can be determined by the connection strength requirements between the wheel arch portion 4 and the pillar portion, such as Figure 1 The side panel rear section assembly shown in FIG. 1 is provided with three connecting reinforcement ribs 5 .

[0042] In this embodiment, the connection reinforcement rib 5 can be integrally formed with the D-pillar and the wheel cover portion 4. Compared with the prior art which requires the use of additional stamping parts to simultaneously connect the wheel cover portion 4 and the D-pillar portion 2, the connection reinforcement rib 5 of this embodiment not only improves the connection strength between the wheel cover portion 4 and the D-pillar portion 2, but also reduces the number of parts, thereby improving the production efficiency of the rear section assembly of the side panel.

[0043] In general, the side panel rear section assembly provided in the embodiment of the present application can be made by an integrated die-casting process, and the material used for the integrated die-casting can be aluminum. The various parts of the side panel rear section assembly can be produced in one piece, and by setting the C-pillar portion 1, the D-pillar portion 2, the wheel cover portion 4 and the rear top cross beam portion 3 to be respectively in different forms of integrated molding, and then with an integrated reinforcement rib structure, the various parts of the side panel rear section assembly can meet the structural strength requirements, and the side panel rear section assembly can be produced in one piece, thereby improving the problems of the long process flow and large number of parts of the side panel rear section assembly in the prior art.

[0044] For reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a top view of the rear top cross beam portion in the embodiment of the present application. Figure 3 It is a bottom view schematic diagram of the rear top cross beam portion in the embodiment of the present application, and the figure is a cross-sectional schematic diagram of the rear top cross beam portion 3 in the embodiment of the present application.

[0045] As an optional embodiment, when the rear top cross beam 3 is specifically provided, the rear top cross beam 3 includes a rear top main beam. The rear top main beam is provided along the width direction of the vehicle body, and one end of the rear top main beam close to the side of the vehicle body is fixedly connected to the top end of the C-pillar portion 1 along the height direction of the vehicle body; the opposite end of the rear top main beam extends to the middle of the vehicle body and is used to connect with the rear top main beam on the other side of the vehicle body to form a cage-type structure of the rear section of the vehicle body.

[0046] Specifically, the rear top main beam includes an integrally formed first sub-beam 31, a second sub-beam 32 and a third sub-beam 33. The first sub-beam 31 is parallel to the height direction of the vehicle body, and the second sub-beam 32 and the third sub-beam 33 are parallel to the length direction of the vehicle body. It should be understood that the first sub-beam 31 is parallel to the height direction of the vehicle body, which means that the width direction of the first sub-beam 31 is parallel to the height direction of the vehicle body; the second sub-beam 32 and the third sub-beam 33 are parallel to the length direction of the vehicle body, which means that the width direction of the second sub-beam 32 and the third sub-beam 33 are parallel to the length direction of the vehicle body; and the length directions of the first sub-beam 31, the second sub-beam 32 and the third sub-beam 33 are all parallel to the width direction of the vehicle body.

[0047] When the rear top main beam is formed together, along the length direction of the vehicle body, the second sub-beam 32 is located at the front side of the first sub-beam 31, and the third sub-beam 33 is located at the rear side of the second sub-beam 32; along the height direction of the vehicle body, the second sub-beam 32 is fixedly connected to the upper end of the first sub-beam 31, and the third sub-beam 33 is fixedly connected to the lower end of the first sub-beam 31. The first sub-beam 31, the second sub-beam 32 and the third sub-beam 33 together constitute a rear top main beam with a bent shape, and the cross-section of the rear top main beam is approximately "Z"-shaped. By arranging the first sub-beam 31, the second sub-beam 32 and the third sub-beam 33 to form a rear top main beam with an approximately "Z"-shaped bend, it is beneficial to obtain a larger sectional inertia moment, thereby improving the bending resistance of the rear top main beam and improving the structural strength of the rear top cross beam portion 3.

[0048] In order to further improve the structural strength of the rear top cross beam portion 3, the rear top cross beam portion 3 further includes a first rear top cross beam reinforcement rib 34 and a second rear top cross beam reinforcement rib 35. The first rear top cross beam reinforcement rib 34 is fixedly connected to both the first sub-beam 31 and the second sub-beam 32; the second rear top cross beam reinforcement rib 35 is fixedly connected to both the first sub-beam 31 and the third sub-beam 33.

[0049] The rear top cross beam 3 in the embodiment of the present application is provided with a bent rear top main beam and a first rear top cross beam reinforcement rib 34 and a second rear top cross beam reinforcement rib 35, so that the integrally formed rear top cross beam 3 has a comparable structural strength to the traditional cylindrical rear top cross beam. In contrast, the cylindrical rear top cross beam needs to be assembled from two or more stamping parts. The rear top cross beam 3 in the embodiment of the present application can be integrally formed with other parts of the side panel rear section assembly, which can reduce the number of parts of the rear top cross beam 3 and improve production efficiency.

[0050] Optional, reference Figure 4When the first rear top cross beam and the second rear top cross beam are specifically arranged, the width L1 of the first rear top cross beam reinforcement rib 34 can be arranged to be greater than the width L2 of the second rear top cross beam reinforcement rib 35 along the length direction of the vehicle body. By arranging the first rear top cross beam reinforcement rib 34 to have a wider width, the structural strength of the rear top cross beam portion 3 can be greatly improved, and by arranging the width of the second rear top cross beam rib to be smaller, more space can be reserved for installing the tailgate hinge and the tailgate support rod.

[0051] In order to improve the stability of the overall structure after the tailgate hinge is installed and the tailgate is connected, some reinforcement structures may be provided on the rear top cross beam portion 3 .

[0052] As an optional implementation, continue to refer to Figure 2 The rear top cross beam portion 3 also includes a hinge mounting platform 36, which is used to fix the hinge of the back door. The hinge mounting platform 36 is integrally formed with the third sub-beam 33 and protrudes outwardly on the upper side of the third sub-beam 33 along the vehicle body height direction. Specifically, the hinge mounting platform 36 can be integrally die-cast with the third sub-beam 33 and the first sub-beam 31, and the hinge mounting platform 36 can be formed by a portion of the third sub-beam 33 protruding upward in the vehicle body height direction. The side edge of the hinge mounting platform 36 close to the first sub-beam 31 is fixedly connected to the first sub-beam 31, and the two side edges of the hinge mounting platform 36 along the vehicle body width direction and the edge of the hinge mounting platform 36 away from the first sub-beam 31 along the vehicle body length direction are connected to the third sub-beam 33 through an integrally formed connecting plate, and the integrally formed connecting plate supports the hinge mounting platform 36 in the vehicle body height direction.

[0053] A spoke reinforcement rib 37 is provided between the hinge mounting platform 36 and the third sub-beam 33, and the spoke reinforcement rib 37 extends from the edge of the hinge mounting platform 36 to the second rear top cross beam reinforcement rib 35 adjacent to the hinge mounting platform 36. Specifically, the spoke reinforcement rib 37 can be fixedly connected to the third sub-beam 33 and the connecting plate at the same time to improve the structural strength of the hinge mounting platform 36.

[0054] When the spoke reinforcement ribs 37 are specifically arranged, multiple spoke reinforcement ribs 37 can be arranged along the edge of the hinge mounting platform 36. Specifically, multiple spoke reinforcement ribs 37 are arranged at intervals along the two side edges of the hinge mounting platform 36 in the width direction of the vehicle body and the rear side edge in the length direction of the vehicle body, and each spoke reinforcement rib 37 extends to the second rear top cross beam reinforcement rib 35 and is fixedly connected to the second rear top cross beam reinforcement rib 35. Multiple spoke reinforcement ribs 37 are arranged at intervals around the hinge mounting platform 36, and cooperate with the connecting plate to jointly support the hinge mounting platform 36, so that the hinge mounting platform 36 has better structural strength. In addition, the hinge mounting platform 36 can be integrally formed with the third sub-beam 33, which can reduce the number of parts of the side panel rear section assembly, shorten the process flow of the side panel rear section assembly, and improve production efficiency.

[0055] As an optional implementation, refer to Figure 3 , along the vehicle body height direction, a support reinforcement rib 38 is provided below the hinge mounting platform 36, and the support reinforcement rib 38 is fixedly connected to the hinge mounting platform 36 and the third sub-beam 33. Specifically, when the hinge mounting platform 36, the third sub-beam 33 and the first sub-beam 31 are integrally die-cast, a groove is formed below the third sub-beam 33 along the vehicle body height direction corresponding to the protruding third sub-beam 33, and the support reinforcement rib 38 is provided in the groove, and is specifically fixedly connected to the connecting plate and the third sub-beam 33. By providing the support reinforcement rib 38, the structural stability of the hinge mounting platform 36 can be further improved, thereby improving the stability of the overall structure when the tailgate hinge and the tailgate are assembled to the rear top cross beam 3.

[0056] Optional, continue to refer to Figure 2 In the embodiment of the present application, the rear top cross beam 3 may also have a back door support connection portion, which is located at one end of the rear top cross beam 3 close to the C-pillar 1. The back door support connection portion can be used to connect a back door support member used to support the back door when the back door is opened, such as a common telescopic support rod. Similar to the hinge mounting platform 36, the back door support connection portion is integrally formed with the third sub-beam 33, and reinforcing ribs similar to the spoke reinforcing ribs 37 are also provided along the edge of the back door support connection portion. These reinforcing ribs can improve the structural strength of the back door support connection portion, and the back door support connection portion can be integrally formed with the third sub-beam 33 to reduce the number of parts of the side panel rear section assembly and improve production efficiency.

[0057] Some implementations of the C-pillar portion 1 and the D-pillar portion 2 are described in detail below.

[0058] As an optional implementation, refer to Figure 1 and Figure 5 , Figure 5 1 is a partial schematic diagram of the C-pillar portion in the embodiment of the present application, wherein the C-pillar portion 1 is provided with a C-pillar reinforcement rib. Specifically, the C-pillar reinforcement rib includes a C-pillar cross rib 11 and a C-pillar longitudinal rib 12, wherein the C-pillar longitudinal rib 12 is arranged at intervals along the height direction of the vehicle body, and the C-pillar cross rib 11 is arranged crosswise between two adjacent C-pillar longitudinal ribs. Figure 5In the example in, when the C-pillar 1 is specifically set, in order to take into account the stability and aesthetics of the vehicle body, the C-pillar 1 can be set to extend generally along the height direction of the vehicle body and can be set at a certain angle to the height direction of the vehicle body. The C-pillar longitudinal ribs 12 will be arranged at intervals along the height direction of the vehicle body, that is, they will be arranged at intervals along the length extension direction of the C-pillar 1, and the C-pillar 1 will be divided into multiple small sections in the height direction of the vehicle body. Between two adjacent C-pillar longitudinal ribs 12, that is, at each small section, there are C-pillar cross ribs 11, and the C-pillar cross ribs 11 are arranged in an "X" shape between two adjacent C-pillar longitudinal ribs 12. By setting the C-pillar longitudinal ribs 12 and the C-pillar cross ribs 11, the one-piece C-pillar 1 has a strong structural strength; and compared with the traditional method of requiring additional stamping parts to reinforce the C-pillar of the vehicle body, it saves additional reinforcement stamping parts, reduces the number of parts, and improves the production efficiency of the rear section assembly of the side panel.

[0059] As an optional implementation, refer to Figure 1 and Figure 6 , Figure 6 This is a partial schematic diagram of the D-pillar portion in the embodiment of the present application. The D-pillar portion 2 is provided with a D-pillar reinforcement rib. Specifically, the D-pillar reinforcement rib includes a D-pillar extension rib 21 and a D-pillar longitudinal rib 22. The D-pillar extension rib 21 and the D-pillar longitudinal rib 22 are both fixed to the side of the D-pillar portion 2 facing the outside of the vehicle body along the vehicle body width direction, and the D-pillar longitudinal rib 22 and the D-pillar extension rib 21 are arranged crosswise.

[0060] When the D-pillar extension ribs 21 are specifically set, along the vehicle body length direction, the D-pillar extension ribs 21 are spaced from the front end of the D-pillar portion 2 to the rear end of the D-pillar portion 2. And in the vehicle body height direction, each D-pillar extension rib 21 extends from the upper end of the D-pillar portion 2 to the lower end of the D-pillar portion 2, and part of the D-pillar extension ribs 21 can be connected to the connecting reinforcement ribs 5 at the connection between the wheel cover portion 4 and the D-pillar portion 2. When the D-pillar longitudinal partition ribs 22 are specifically set, along the vehicle body height direction, the D-pillar longitudinal partition ribs 22 are spaced from the upper end of the D-pillar portion 2 to the lower end of the D-pillar portion 2. And along the vehicle body length direction, each D-pillar longitudinal partition rib 22 extends from the front end of the D-pillar portion 2 to the rear end of the D-pillar portion 2. By providing the D-pillar extension rib 21 and the D-pillar longitudinal partition rib 22, the one-piece D-pillar portion 2 has a stronger structural strength; and compared with the traditional method of requiring additional stamping parts to reinforce the D-pillar of the vehicle body, additional reinforcing stamping parts are saved, the number of parts is reduced, and the production efficiency of the rear section of the side panel assembly is improved.

[0061] It is worth noting that the fact that the D-pillar extension rib 21 extends from the upper end of the D-pillar portion 2 to the lower end of the D-pillar portion 2 does not mean that the D-pillar extension rib 21 is necessarily parallel to the height direction of the vehicle body, and the fact that the D-pillar longitudinal partition rib 22 extends from the front end of the D-pillar portion 2 to the rear end of the D-pillar portion 2 does not mean that the D-pillar longitudinal partition rib 22 is necessarily parallel to the length direction of the vehicle body. Figure 6As shown in the example, the D-pillar portion 2 is arranged along the vehicle body height direction as a whole, but in order to match the overall spatial structure design requirements of the vehicle body, the D-pillar portion 2 itself has a bent shape. As a specific example, starting from the top end of the D-pillar portion 2 in the opposite direction of the vehicle body height and extending downward gradually toward the front side in the length direction of the vehicle body, after a distance, the D-pillar portion 2 begins to bend and extends to the wheel housing portion 4 in a path parallel to the vehicle body height direction and is integrally connected to the wheel housing portion 4. In order to match the bending shape of the D-pillar portion 2, the D-pillar extension rib 21 also has a D-pillar extension rib 21 with the same bending extension shape as the D-pillar portion 2. And when setting the D-pillar longitudinal partition rib 22, each D-pillar longitudinal partition rib 22 can be set to remain perpendicular to the D-pillar extension rib 21 at its setting position; that is, as shown in FIG. Figure 6 The D-pillar longitudinal ribs 22 are arranged in the middle, when the D-pillar extension ribs 21 form a certain angle with the height direction of the vehicle body, the D-pillar longitudinal ribs 22 also form a certain angle with the length direction of the vehicle body. This arrangement can improve the uniformity of the overall distribution of the D-pillar extension ribs 21 and the D-pillar longitudinal ribs 22 in the D-pillar portion 2, which is conducive to improving the uniformity of the overall structural strength of the D-pillar portion 2.

[0062] As an optional implementation, continue to refer to Figure 1 The wheel cover portion 4 is provided with a wheel cover flange 41 at the rear side of the D-pillar portion 2 along the length direction of the vehicle body. Specifically, the wheel cover flange 41 can be located at the outer edge of the wheel cover portion 4 and turned out toward the outside of the vehicle body along the width direction of the vehicle body. A flange reinforcement rib 42 is also fixed between the wheel cover portion 4 and the wheel cover flange 41. The flange reinforcement rib 42 is arranged at intervals along the edge of the wheel cover portion 4. Specifically, the flange reinforcement rib 42 can be located on the inner side of the folding angle between the wheel cover portion 4 and the wheel cover flange 41. The wheel cover flange 41 can be used to cooperate with the outer covering of the vehicle body and to enhance the structural strength of the edge of the wheel cover portion 4. Secondly, the structural strength of the edge of the wheel cover portion 4 can be further enhanced by arranging the flange reinforcement rib 42. In addition, the wheel cover flange 41 and the flange reinforcement rib 42 can be integrally formed with the wheel cover portion 4, which can reduce the number of parts of the rear section assembly of the side enclosure and improve production efficiency.

[0063] As an optional implementation, the side panel rear section assembly provided in the embodiment of the present application further includes a rear longitudinal beam portion 6. Figure 1 and Figure 6 The rear longitudinal beam portion 6 is integrally formed with the C-pillar portion 1, the D-pillar portion 2, the rear roof cross beam portion 3 and the wheel housing portion 4. The rear longitudinal beam portion 6 can be used as a part of the roof longitudinal beam, extending backward from the top of the C-pillar portion 1 in the vehicle body height direction to the top of the D-pillar portion 2 in the vehicle body height direction.

[0064] Specifically, the rear longitudinal beam portion 6 includes a rear longitudinal beam main beam and a rear longitudinal beam reinforcement rib 62. The rear longitudinal beam 61 is located between the C-pillar portion 1 and the D-pillar portion 2, and the two opposite ends of the rear longitudinal beam 61 are integrally connected to the upper end of the C-pillar portion along the vehicle body height direction and the upper end of the D-pillar portion 2 along the vehicle body height direction. The rear longitudinal beam 61, as the main structural component of the rear longitudinal beam portion 6, plays the role of connecting the C-pillar portion 1 and the D-pillar portion 2, and forms a rear triangular window of the vehicle body with the C-pillar portion 1 and the D-pillar portion 2. By arranging the rear longitudinal beam main beam to be integrally connected with the C-pillar portion 1 and the D-pillar portion 2, the connection strength at the connection between the rear longitudinal beam 61 and the C-pillar portion 1 and the D-pillar portion 2 is relatively high, and the number of parts of the rear section assembly of the side panel can be reduced during the production process, thereby improving production efficiency.

[0065] In order to improve the structural strength of the rear longitudinal beam 61 itself, the rear longitudinal beam portion 6 also includes a rear longitudinal beam reinforcement rib 62. Specifically, the cross section of the rear longitudinal beam 61 is an inverted "L" shape, and the rear longitudinal beam reinforcement rib 62 is arranged inside the corner of the "L"-shaped rear longitudinal beam 61. When the rear longitudinal beam reinforcement rib 62 is specifically arranged, the reinforcement ribs of the rear longitudinal beam 61 are arranged at intervals inside the corner of the rear longitudinal beam 61 along the direction in which the rear longitudinal beam 61 extends from the C-pillar portion 1 to the D-pillar portion 2, and the specific spacing distance of the reinforcement ribs of the rear longitudinal beam 61 can be determined by the required structural strength of the rear longitudinal beam portion 6.

[0066] By providing an "L"-shaped rear longitudinal main beam 61 and a rear longitudinal beam reinforcement rib 62, the rear longitudinal beam portion 6 can have a structural strength equivalent to that of a cylindrical rear longitudinal beam assembled from two pieces of stamping materials in the prior art through an integrated manufacturing form, and can reduce the number of parts of the side panel rear section assembly during the production process, thereby improving the production efficiency of the side panel rear section assembly.

[0067] The embodiment of the present application also provides a car, the body of the car includes any one of the side panel rear section assemblies as described above. Specifically, the number of the side panel rear section assemblies included in the body can be two, the two side panel rear section assemblies are both located at the rear end of the body along the body length direction, and the two side panel rear section assemblies are respectively located on both sides of the body along the body width direction. The two side panel rear section assemblies are symmetrically arranged, the two rear top cross beams are relatively arranged and both extend toward the middle of the body along the body width direction, and one end of the rear top cross beam near the middle of the body along the body width direction is fixedly connected to one end of the other rear top cross beam near the middle of the body along the body width direction.

[0068] In the automobile in the above scheme, various parts of the side panel rear section assembly are formed in one piece, and by arranging the C-pillar portion, the D-pillar portion, the wheel cover portion and the rear roof cross beam portion to be formed in different forms respectively, and then cooperating with the one-piece formed reinforcing rib structure, while the various parts of the side panel rear section assembly can meet the structural strength requirements, the one-piece molding production of the side panel rear section assembly is realized, thereby improving the problems of the long process flow and large number of parts of the side panel rear section assembly in the prior art.
