[0041] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the usual meanings 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 include 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 position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0043] To facilitate understanding of the side panel assembly provided in the embodiment of the present application, its application scenario is first explained. The side panel assembly provided in the embodiment of the present application can be applied to vehicles, and in particular to automobiles. The side panel assembly is an important component of the vehicle body structure, and usually includes parts such as the A-pillar, B-pillar, C-pillar, and door sills. Some models include a D-pillar. The side panel assembly usually also includes the front part of the side panel located inside the front fender, the rear part of the side panel inside the rear fender, and the like. The traditional production method of the side panel assembly is to divide the side panel assembly into several parts during the design stage, and then produce each part separately by stamping steel, stamping aluminum, and a mixture of steel and aluminum, and then weld and assemble the parts to form an overall side panel assembly.

[0044] However, existing stamping and welding solutions have certain drawbacks. For example, the design process must not only meet the structural strength requirements of each component, but also consider the final assembly fit and the structural strength of the overall side panel assembly after assembly, resulting in a complex design process. Furthermore, since each component must be stamped separately during production, the production process involves multiple steps and molds, which inevitably lengthens the entire process. Furthermore, for an assembly, a greater number of parts means greater difficulty in controlling overall dimensional accuracy, which undoubtedly increases costs.

[0045] To this end, the present application provides a side panel assembly that integrates multiple components into an integrated design. Each component is designed with a different structure to meet structural strength requirements. This is intended to address the issues of lengthy process flows and a large number of parts in existing side panel assemblies. The following, in conjunction with the accompanying drawings, details the side panel assembly provided by the present application.

[0046] For reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the side panel assembly in an embodiment of the present application as viewed from the outside of the vehicle body. Figure 2 This is a schematic diagram of the side panel assembly in the embodiment of the present application viewed from the inside of the vehicle body. Figure 1 as well as Figure 2 As shown, the side panel assembly provided in the embodiment of the present application is an integrally formed structure, specifically comprising an integrally formed side panel front portion 1, an A-pillar portion 2, a B-pillar portion 3, a C-pillar portion 4, a side panel rear portion 5, and a side sill portion 6. The side panel front portion 1 is located within the front fender of the vehicle, and the side panel rear portion 5 is located within the rear fender of the vehicle. The A-pillar portion 2 primarily constitutes the vehicle's A-pillar and is located in front of and to the side of the driver and front passenger seats. The B-pillar portion 3 primarily constitutes the vehicle's B-pillar and is located between the front and rear doors. The C-pillar portion 4 primarily constitutes the vehicle's C-pillar and is located behind the rear door. The side sill portion 6 is integrally located at the lower end of the side panel assembly along the vehicle body height direction and extends to connect the side panel front portion 1, the B-pillar portion 3, and the side panel rear portion 5. Furthermore, a roof rail is provided at the upper end of the side panel assembly along the vehicle body height direction, connecting the top ends of the B-pillar portion 3 and the C-pillar portion 4 along the vehicle body length direction.

[0047] For reference Figure 1 and Figure 3 , Figure 3 This is a partial view of the A-pillar portion 2 in the embodiment of the present application. Figure 3 As shown in , the A-pillar portion 2 has an A-pillar groove structure, and the A-pillar portion 2 is also provided with an A-pillar reinforcement rib, and the A-pillar reinforcement rib 22 is integrally formed with the A-pillar reinforcement rib 21. Specifically, the A-pillar reinforcement rib 21 is constructed as a groove structure with an opening on one side. Optionally, the opening of the groove can be toward the outside of the vehicle body or the inside of the vehicle body, which can be determined by the design of the stamping die. The A-pillar reinforcement rib 22 is integrally formed in the A-pillar reinforcement rib 21 to improve the structural strength of the A-pillar portion 2. The structural strength of the automobile A-pillar is of vital importance to the safety performance of the entire vehicle. In the embodiment of the present application, the structural strength requirements of the automobile A-pillar can be met by the integrally formed A-pillar reinforcement rib 21 and by providing the A-pillar reinforcement rib 22. Compared with the traditional structure of preparing the A-pillar separately and then welding it to the side assembly, this integrally formed structure saves a lot of process steps and is conducive to improving production efficiency.

[0048] For reference Figure 4 and Figure 5 , Figure 4 This is a partial schematic diagram of the B-pillar portion 3 in the embodiment of the present application. Figure 5 This is a schematic cross-sectional view of the B-pillar in the embodiment of this application. Figure 4 and Figure 5 As shown, the B-pillar portion 3 in the embodiment of the present application is an entire plate-like structure 31, and is provided with B-pillar reinforcement ribs 32. The B-pillar reinforcement ribs 32 are integrally formed and arranged on both sides of the B-pillar portion 3 along the width direction of the vehicle body. Specifically, the plate-like structure 31 that constitutes the entire B-pillar is arranged parallel to the side of the vehicle body, and the B-pillar reinforcement ribs 32 extend from the upper end of the B-pillar portion 3 to the lower end along the height direction of the vehicle body.

[0049] Similar to the setting principle of the one-piece A-pillar portion 2, the B-pillar portion 3, through the one-piece plate-shaped body structure and the one-piece B-pillar reinforcement rib 32, can meet the structural strength requirements of the automobile B-pillar while saving a large number of process steps, which is conducive to improving production efficiency.

[0050] For reference Figure 6 and Figure 7 , Figure 6 This is a partial schematic diagram of the threshold portion 6 in the embodiment of the present application. Figure 7 Schematic diagram of the cross section of the threshold portion 6 in the embodiment of the present application. Figure 6 as well as Figure 7 As shown, the rocker section 6 has a continuous, wavy shape, forming a cylindrical rocker. This continuous bend occurs along the vehicle height. Specifically, from top to bottom, the rocker material bends in a continuous "W" shape along the vehicle width, toward the vehicle interior and the door exterior. Along the vehicle length, the rocker section 6 maintains a continuous curved cross-section, extending from the front side panel 1 to the rear side panel 5.

[0051] The continuously folded structure of the rocker 6 meets the vehicle's bending resistance and overall strength requirements. Compared to the traditional method of stamping the rocker separately and then welding it to the side panel assembly, the integrated rocker 6 reduces welding operations, helps control assembly errors within the side panel assembly, improves production efficiency, and reduces the number of parts in the side panel assembly.

[0052] In general, the side panel assembly provided in the embodiments of the present application can be manufactured using an integrated die-casting process, with aluminum being the material used for the integrated die-casting. By arranging the various components of the side panel assembly as one piece, and by arranging the A-pillar 2, B-pillar 3, and door sill 6 as separate, integrated forms, and combining them with an integrated reinforcement rib structure, the side panel assembly is manufactured as an integrated piece while meeting the structural strength requirements of the various components. This improves the existing side panel assembly process, which suffers from a long production process and a large number of parts.

[0053] As an optional embodiment, when the side panel assembly provided in the embodiment of the present application is specifically implemented, the side panel assembly further includes an integrally formed A-pillar lower portion 8, which is referred to as Figure 1 and Figure 2 The lower portion of the A-pillar 8 is located at the intersection of the side panel front portion 1, the A-pillar portion 2 and the door sill portion 6. The lower portion of the A-pillar 8 is provided with a front door hinge mounting portion and is used to mount and fix the front door hinge. Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the side panel front reinforcement rib 11 in the embodiment of the present application. Figure 9 This is a schematic diagram of the A-pillar lower portion 8 reinforcement rib 81 in an embodiment of the present application. The A-pillar lower portion 8 is integrally connected to the side panel front portion 1, and is provided with an integrally formed A-pillar lower portion 8 reinforcement rib 81. The side panel front reinforcement rib 11 and the A-pillar lower portion 8 reinforcement rib 81 are separated by the connecting line between the side panel front portion 1 and the A-pillar lower portion 8. Along the length of the vehicle body, the side panel front reinforcement rib 11 extends forward from the connecting line between the side panel front portion 1 and the A-pillar lower portion 8, while the A-pillar lower portion 8 reinforcement rib 81 extends rearward from the connecting line between the side panel front portion 1 and the A-pillar lower portion 8.

[0054] like Figure 8 As shown, the overall layout of the side panel front reinforcement ribs 11 is a cross honeycomb pattern. From front to back along the length of the vehicle body, the side panel front reinforcement ribs 11 are densely arranged along two routes: one route runs from the side panel front 1 to the A-pillar 2, and the other route runs from the side panel front 1 to the side sill 6. This arrangement facilitates the front side panel reinforcement ribs 11 to transfer more impact force to the A-pillar 2 and side sill 6, which have greater structural strength, during a collision, thereby protecting the cockpit located between the A-pillar 2 and side sill 6.

[0055] For reference Figure 9 The reinforcement plate of the lower part 8 of the A-pillar is arranged horizontally and vertically along the length direction and height direction of the vehicle body. This arrangement can make the overall rigidity of the lower part 8 of the A-pillar stronger. When the vehicle collides, the lower part 8 of the A-pillar serves as a rigidity retention area, which can better limit the deformation of the vehicle from invading the cockpit, thereby better protecting the occupants.

[0056] Along the width of the vehicle body, the front side panel reinforcement rib 11 is integrally formed on the outward-facing side of the front side panel 1. This allows for more space on the inward-facing side of the front side panel 1 during vehicle assembly for mounting the vehicle's shock absorber mechanism. The reinforcement rib 81 on the lower A-pillar 8 is located on the inward-facing side of the lower A-pillar 8. Adjustments to the reinforcement structure of the lower A-pillar 8 will not affect the installation of the door hinges.

[0057] As an optional implementation, please refer to Figure 1 and Figure 3 The A-pillar reinforcement ribs 22 include A-pillar longitudinal partition ribs 221 and A-pillar cross ribs 222; wherein, a plurality of A-pillar longitudinal partition ribs 221 are arranged perpendicular to the extension direction of the A-pillar portion 2 and are arranged at intervals, dividing the A-pillar reinforcement ribs 21 into a plurality of A-pillar sub-groove structures arranged along the extension direction of the A-pillar portion 2. By providing the A-pillar longitudinal partition ribs 221, the groove shape retention capability of the A-pillar reinforcement ribs 21 can be improved. Within each A-pillar sub-groove structure, the A-pillar cross ribs 222 are arranged in an X-shaped cross. By providing a continuous cross-arrangement of the A-pillar cross ribs 222, the overall bending resistance of the A-pillar portion 2 can be improved, and when the vehicle collides, the rigidity retention capability of the A-pillar portion 2 can be further improved, thereby protecting the occupants.

[0058] As an optional implementation, please refer to Figure 4 and Figure 5 , multiple B-pillar reinforcement ribs 32 are arranged at intervals along the length direction of the vehicle body on both sides of the B-pillar portion 3 along the width direction of the vehicle body. And along the width direction of the vehicle body, the height of the B-pillar reinforcement rib 32 located on the outer side of the vehicle body is smaller than the height of the B-pillar reinforcement rib 32 located on the inner side of the vehicle body. Figure 5 As shown, B-pillar reinforcement ribs 32 are provided on both sides of the vehicle body in the width direction, which can effectively improve the bending strength of the B-pillar portion 3. The height of the B-pillar reinforcement rib 32 on the exterior side is smaller than that on the interior side. This facilitates the installation of glass or other exterior body panels outside the B-pillar portion 3, allowing the position of the glass or other exterior body panels to better match the thickness of the vehicle door, thereby improving the overall aesthetics of the vehicle.

[0059] Further optional, such as Figure 5As shown, on the interior side of the vehicle along the vehicle's width, the B-pillar reinforcement ribs 32 located on either side of the vehicle's length have a greater height along the vehicle's width than the B-pillar reinforcement ribs 32 located in the middle of the vehicle's length. In other words, on the interior side of the vehicle, along the vehicle's length, the multiple B-pillar reinforcement ribs 32 are arranged with higher ribs on the sides and lower ribs in the middle. This arrangement not only meets the styling and functional requirements of the B-pillar interior panel, but also requires high structural strength, particularly a large moment of inertia, to maintain the shape of the passenger compartment during a collision. For the B-pillar 3, increasing the height of the B-pillar reinforcement ribs 32 on either side of the vehicle's length further improves the overall bending strength of the B-pillar 3. Therefore, by providing taller ribs on both sides, the structural strength of the B-pillar 3 can be significantly improved with less material, resulting in better economics.

[0060] In an optional embodiment, reference is made to Figure 6 and Figure 7 The rocker 6 is located at the lower end of the side panel assembly along the vehicle body height direction. The rocker 6 includes a first bent portion 61 and a second bent portion 62, which are formed integrally and spaced apart along the vehicle body height direction. Both the first bent portion 61 and the second bent portion 62 have a convex shape formed by bending the side panel body toward the vehicle body interior. Rockers in traditional side panel assemblies are generally sheet metal box-shaped structures or extruded profile structures. However, these two types of rockers require separate production and welding, and cannot be integrally molded with other side panel assembly components. In contrast, the rocker 6 in the embodiment of the present application, through its integrally molded bent structure, meets structural strength requirements, thereby enabling the rocker 6 to be integrally molded with other components of the side panel assembly.

[0061] Continue to refer Figure 7 , between the first bend portion 61 and the second bend portion 62, the threshold portion 6 is further provided with an integrally formed threshold reinforcement plate 63. The door panel reinforcement plate is provided to play a similar role as the bend portion, and is used to strengthen the overall structural strength of the threshold portion 6. The threshold reinforcement plate 63 can be equivalent to another bend portion provided between the first bend portion 61 and the second bend portion 62, but if another bend portion is provided between the first bend portion 61 and the second bend portion 62, the continuous and dense bend structure will increase the risk of the mold producing a thin steel effect. By providing the threshold reinforcement plate 63, while the threshold reinforcement plate 63 improves the structural strength of the threshold portion 6, it can also reduce the risk of the mold producing a thin steel effect, thereby increasing the service life of the mold.

[0062] Further optional, continue to refer to Figure 7When designing the first and second bends 61 and 62, the first bend 61 is positioned above the second bend 62 along the vehicle body height direction, and the width of the first bend 61 protruding toward the vehicle body is greater than the width of the second bend 62 protruding toward the vehicle body. During vehicle assembly, the area where the second bend 62 will be located provides more space for the battery pack without moving the rocker 6 outward. This ensures easier installation while meeting the required strength of the rocker 6.

[0063] As an optional implementation, refer to Figure 10 , Figure 10 Schematic diagram of the C-pillar reinforcement rib 41 in the embodiment of the present application. Figure 10 As shown, a first C-pillar reinforcement rib 41 is provided on the side of the C-pillar portion 4 facing the interior of the vehicle body. Specifically, the C-pillar reinforcement rib 41 extends upward from the lower end of the C-pillar portion 4 to the connection between the side panel assembly and the rear roof crossbar of the vehicle along the height direction of the vehicle body. The provision of the C-pillar reinforcement rib 41 not only enhances the structural strength of the C-pillar portion 4 itself, but also effectively maintains the shape of the passenger compartment in the event of a collision, thereby protecting the occupants. Furthermore, by extending the C-pillar reinforcement rib 41 from the lower end along the height direction of the vehicle body to the connection between the side panel assembly and the rear roof crossbar of the vehicle, after the vehicle is assembled, the C-pillar reinforcement rib 41 can help transfer the impact force from the lower part of the vehicle body upward to the roof crossbar, thereby facilitating the overall vehicle body frame to share the impact, thereby improving the overall structural stability of the vehicle body.

[0064] Continue to refer Figure 10 In the specific implementation of the side assembly, some larger models, such as some SUV (Sport Utility Vehicle) models, in addition to the A-pillar, B-pillar, and C-pillar, also have a D-pillar, which is generally located behind the C-pillar. Figure 11 and 11 The side panel assembly shown in FIG further includes a D-pillar portion 9. When the side panel assembly includes the D-pillar portion 9, the D-pillar portion 9 is integrally formed with other parts of the side panel assembly, and a D-pillar reinforcement rib is provided on the D-pillar portion 9. Figure 11 The D-pillar reinforcement ribs extend downward and upward along the vehicle body height direction. This arrangement, similar to the C-pillar portion 4, also provides good structural strength for the D-pillar portion 9. Furthermore, the D-pillar reinforcement ribs effectively transfer impact forces to the roof rails, allowing the entire vehicle body frame to share the impact, thereby improving the overall structural stability of the vehicle body.

[0065] In order to further improve the stability of the vehicle body structure, optionally, refer to Figure 11 , Figure 11 This is a schematic diagram of the box-shaped platform 51 in the embodiment of the present application. A box-shaped platform 51 is also provided at the connection between the D-pillar portion 9 and the side panel rear portion 5. The box-shaped platform 51 is located on the side of the side panel rear portion 5 facing the interior of the vehicle body, and the box-shaped platform 51 is located at the lower end of the C-pillar portion 4 along the vehicle body height direction. Specifically, the box-shaped platform 51 is also integrally formed with the side panel rear portion 5, and is constructed as a box-shaped platform 51 that protrudes outward along the vehicle body width direction toward the exterior side of the vehicle body. The upper end of the box-shaped platform 51. During vehicle assembly, the box-shaped platform 51 is used to connect to the rear suspension. By providing the box-shaped platform 51, the impact force of the rear suspension on the side panel rear portion 5 can be evenly transmitted upward to the D-pillar portion 9 with stronger structural strength through the box-shaped platform 51, thereby improving the stability of the connection between the side panel assembly and the suspension.

[0066] The present application also provides an automobile, wherein the automobile body includes any of the above-described side panel assemblies. It should be understood that the automobile body typically includes two sets of side panel assemblies, one located on either side of the width of the automobile body. When specifically arranging the side panel assemblies, the two side panel assemblies located on either side of the width of the automobile body should be arranged in mirror-symmetric fashion.

[0067] The automobile body includes a side panel assembly, which is formed in one piece by arranging the various parts of the side panel assembly, and by arranging the A-pillar part, the B-pillar part and the door sill part to be formed in different forms respectively, and then combined with an integrally formed reinforcing rib structure, while the various parts of the side panel assembly can meet the structural strength requirements, the side panel assembly is produced in one piece, thereby improving the problems of the existing technology of the side panel assembly having a long process flow and a large number of parts.

[0068] The one or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.

[0069] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
