Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a vehicle side wall, a body-in-white and a vehicle. BACKGROUND

[0002] The vehicle side wall assembly is an important part of the vehicle body-in-white, and has a key influence on the results of the vehicle precision, stiffness, efficiency, lightweight, collision and other indicators.

[0003] Traditionally, when preparing the side wall assembly, the side wall assembly needs to be divided into different structural parts, and each small structural part needs to be prepared by stamping process, etc. first, and then each structural part is assembled together by welding, etc.

[0004] The traditional method has the following problems:

[0005] Firstly, the assembly process is complex and involves stamping, welding, painting, and overall assembly.

[0006] Secondly, the stamping plate is an equal thickness plate, which cannot structureally reinforce the structure with a deep stamping depth; if the overall stiffness needs to be improved, only the plate thickness can be increased, which will increase the overall weight of the vehicle; or, a reinforcing part can be added, which will increase the process complexity, reduce the overall precision of the vehicle, and also reduce the manufacturing efficiency.

[0007] Therefore, there is an urgent need in the prior art for a vehicle side wall assembly with fewer and simpler process steps and better manufacturing efficiency and weight reduction. SUMMARY

[0008] One of the purposes of the present application is to provide a vehicle side wall to solve the technical problem of the complex process of the prior art side wall preparation; the second purpose of the present application is to provide a body-in-white; and the third purpose of the present application is to provide a vehicle.

[0009] In order to achieve the above purposes, the technical solution adopted by the present application is as follows:

[0010] A vehicle side wall, comprising a side wall main body and a rear side wall, the side wall main body and the rear side wall are prepared by one-piece die casting.

[0011] According to the above technical solution, the vehicle side panel is manufactured using an integrated die-casting process to form the main body and rear side panel. The manufactured main body and rear side panel are a single integrated structure, formed in a single step. Compared to the existing technology that separately manufactures the main body and rear side panel components and then assembles them by welding, this method eliminates the assembly process and time. Furthermore, it avoids the need for multiple separate steps and processes to manufacture individual components, saving equipment, processes, and time. In addition, because the main body and rear side panel are an integrated structure, there are no assembly errors caused by the connection and fixing of individual components. This allows for better assembly precision when assembling the vehicle side panel with other structural components of the vehicle. For the vehicle, the integrated structure of the main body and rear side panel provides better collision and torsional performance. Furthermore, the side panel body and rear side panel are manufactured using a one-piece die-casting method, typically using aluminum or aluminum alloys. Aluminum and aluminum alloys possess excellent corrosion and rust resistance; therefore, the overall structure of the side panel body and rear side panel does not require a surface coating for corrosion and rust prevention, eliminating the need for electrophoresis or spraying processes. Moreover, using aluminum for the entire vehicle side panel significantly reduces its weight compared to the ordinary steel used in existing technologies, thus contributing to a reduction in the overall vehicle weight. In addition, from a manufacturing process perspective, the production of the side panel body and rear side panel involves only a one-piece die-casting process, which can be performed on a single die-casting machine. The entire manufacturing process of the vehicle side panel eliminates the need for stamping and welding processes. For vehicle manufacturers, this reduces the need for stamping and welding equipment, allowing for a reduction in the size of stamping and welding workshops, thereby reducing manufacturing equipment and workshop space and ultimately significantly lowering costs.

[0012] Furthermore, the side panel body includes a sill, an upper beam, and a plurality of first pillars arranged along the front-rear direction of the vehicle; the plurality of first pillars are located on the front and rear sides adjacent to the vehicle doors.

[0013] According to the above technical solution, in the vertical direction, the side panel includes a sill located on the lower side and an upper side beam located on the upper side. In the front-rear direction, the side panel includes multiple first pillars, which are distributed on the front and rear sides of the vehicle door. That is, the side panel 1 encloses the vehicle door and roughly corresponds to the passenger compartment of the vehicle (except for two-door four-seat models and three-row SUVs, in which the passenger compartment is larger than the area enclosed by the side panel). The side panel serves to protect the door and the passenger compartment.

[0014] Furthermore, the plurality of first pillars includes pillar A; pillar A includes a column area; the column area of ​​pillar A is provided with a first reinforcing rib group and a second reinforcing rib group; the first reinforcing rib group includes a plurality of first reinforcing ribs, each first reinforcing rib is arranged along the front-back direction, and the plurality of first reinforcing ribs are spaced apart in the vertical direction; the second reinforcing rib group includes one or more second reinforcing ribs, the second reinforcing ribs are arranged along the vertical direction and intersect with the plurality of first reinforcing ribs.

[0015] According to the above technical solution, the pillar area of ​​the A-pillar is the lower part of the A-pillar. The first reinforcing ribs arranged along the front-rear direction on the pillar area of ​​the A-pillar can resist the impact force from the front of the vehicle; the second reinforcing ribs arranged vertically can connect multiple first reinforcing ribs to form a mesh structure, which can improve the stability of the force and the upper limit of the impact force resistance, thereby better protecting the A-pillar, as well as the vehicle and passengers.

[0016] Furthermore, the column area of ​​the A-pillar is also provided with a third reinforcing rib group, which includes multiple third reinforcing ribs. The third reinforcing ribs are formed at the junction of the first reinforcing rib and the second reinforcing rib. The dimension of the third reinforcing rib in the front-back direction is greater than the thickness of the second reinforcing rib, and the dimension in the vertical direction is greater than the thickness of the first reinforcing rib.

[0017] According to the above technical solution, a third reinforcing rib is provided at the junction of the first reinforcing rib and the second reinforcing rib. The third reinforcing rib has a larger radial dimension, that is, it is thicker and thicker than the first and second reinforcing ribs. It can withstand greater impact forces, thereby effectively ensuring the transmission of forces in different directions and enhancing the performance of the first and second reinforcing rib groups in resisting external impact forces.

[0018] Furthermore, the plurality of first pillars includes an A-pillar; the A-pillar includes an upper enclosure area; the upper enclosure area of ​​the A-pillar is provided with a fourth reinforcing rib group, a fifth reinforcing rib group, and a sixth reinforcing rib group; the fourth reinforcing rib group includes one or more fourth reinforcing ribs, which are arranged along the front-back direction and match the shape of the upper enclosure area of ​​the A-pillar; the fifth reinforcing rib group includes a plurality of fifth reinforcing ribs, each of which extends along the left-right direction and is spaced apart in the front-back direction; the sixth reinforcing rib group includes a sixth reinforcing rib, which is arranged along the front-back direction and is serrated or wavy, and each sixth reinforcing rib connects between the fourth and fifth reinforcing ribs and forms a triangular structure with the fourth and fifth reinforcing ribs.

[0019] According to the above technical solution, in this embodiment, the upper side enclosure of the A-pillar is the upper region of area A, which roughly corresponds to the window glass of the vehicle door. The shape of the upper side enclosure of the A-pillar is generally a columnar structure with the upper end sloping backward. A fourth reinforcing rib is provided on the upper side enclosure of the A-pillar, extending along the frontal direction and the shape of the upper side enclosure, which can resist the impact force from the front of the vehicle. A fifth reinforcing rib is provided on the upper side enclosure of the A-pillar, extending along the left-right direction, which can resist the impact force from the side of the vehicle. A sixth reinforcing rib is provided on the upper side enclosure of the A-pillar in a sawtooth or wavy shape, which connects with the fourth and fifth reinforcing ribs to form a triangular structure, which can enhance the stability of the reinforcing rib structure in the upper side enclosure, ensure that the shape of the upper side enclosure does not deform, and thus effectively protect the vehicle door and passenger compartment during a vehicle collision.

[0020] Furthermore, the plurality of first pillars shown includes a B pillar; the B pillar is provided with a seventh reinforcing rib group and an eighth reinforcing rib group; the seventh reinforcing rib group includes a plurality of seventh reinforcing ribs, each of the seventh reinforcing ribs is arranged in the front-back direction, and the plurality of seventh reinforcing ribs are spaced apart in the vertical direction; the eighth reinforcing rib group includes one or more eighth reinforcing ribs, the eighth reinforcing ribs are arranged in the vertical direction and intersect with the plurality of seventh reinforcing ribs.

[0021] According to the above technical solution, the seventh reinforcing rib set along the front-rear direction on the B-pillar can resist the impact force from the side of the vehicle; the eighth reinforcing rib set along the vertical direction can connect multiple seventh reinforcing ribs to form a mesh structure, which improves the stability of the force and the upper limit of the impact force resistance. In the event of a collision, the force is distributed as a whole, avoiding local force concentration that could lead to local breakage of the B-pillar, thus better protecting the B-pillar and the vehicle and its occupants.

[0022] Furthermore, the threshold is provided with a ninth reinforcing rib group, a tenth reinforcing rib group, and an eleventh reinforcing rib group; the ninth reinforcing rib group includes one or more ninth reinforcing ribs, each of which is arranged along the front-to-back direction, and the plurality of ninth reinforcing ribs are spaced apart in the vertical direction; the tenth reinforcing rib group includes a plurality of tenth reinforcing ribs, each of which is arranged obliquely downward in the front-to-back direction, and the plurality of tenth reinforcing ribs are spaced apart in the front-to-back direction; the eleventh reinforcing rib group includes a plurality of eleventh reinforcing ribs, each of which is arranged obliquely upward in the front-to-back direction, and the plurality of eleventh reinforcing ribs are spaced apart in the front-to-back direction; the ninth, tenth, and eleventh reinforcing ribs intersect to form a triangular mesh structure.

[0023] According to the above technical solution, the ninth reinforcing rib, which is set in the front-rear direction inside the door sill, can resist the impact force from the front of the vehicle. The tenth and eleventh reinforcing ribs, which are set in the diagonal direction inside the door sill, can intersect with the ninth reinforcing rib to form a triangular mesh structure. This mesh structure can improve the strength and stability of the reinforcing rib structure, enhance the resistance to frontal collision force of the vehicle, and also resist the collision force from the side, thereby effectively protecting the vehicle door and passenger compartment when the vehicle is involved in a collision.

[0024] Furthermore, the fourth reinforcing rib group extends rearward to the rear end of the upper beam; the upper beam is provided with a twelfth reinforcing rib group and a thirteenth reinforcing rib group; the twelfth reinforcing rib group includes multiple twelfth reinforcing ribs, each of which extends in the left-right direction, and the multiple twelfth reinforcing ribs are spaced apart in the front-back direction; the thirteenth reinforcing rib group includes a thirteenth reinforcing rib, which is arranged in the front-back direction and is serrated or wavy, and each thirteenth reinforcing rib connects between the fourth and twelfth reinforcing ribs and forms a triangular structure with the fourth and twelfth reinforcing ribs.

[0025] According to the above technical solution, the fourth reinforcing rib, located on the upper side of the A-pillar, extends rearward to the rear end of the upper side beam. This fourth reinforcing rib, extending into the upper side beam, can also resist the frontal impact force of the vehicle. Furthermore, a twelfth reinforcing rib, extending laterally, is provided on the upper side beam to resist impact forces from the side of the vehicle. A thirteenth reinforcing rib, shaped like a sawtooth or wave, is provided on the upper side beam. This thirteenth rib, connected to the fourth and twelfth reinforcing ribs, forms a triangular structure, enhancing the stability of the reinforcing rib structure in the upper side beam and ensuring that the shape of the upper side beam does not deform. This effectively protects the vehicle doors and passenger compartment during a collision.

[0026] Furthermore, the rear side panel includes a rear wheel arch; or, the rear side panel includes a rear wheel arch and a second pillar; the second pillar is located on the rear side of the vehicle door and away from the door.

[0027] According to the above technical solution, the rear side panel includes a rear wheel cover and a second pillar, or includes a rear wheel cover, that is, the rear wheel cover and the second pillar are formed together, or the rear wheel cover is formed synchronously with the aforementioned side panel body in a one-time die-casting process, and are an integral structure.

[0028] Furthermore, the rear wheel arch is provided with a fourteenth reinforcing rib group; the fourteenth reinforcing rib group is located on the inner side of the rear side panel, and the fourteenth reinforcing rib group includes multiple fourteenth reinforcing ribs, which surround the rear wheel hub of the vehicle and are spaced apart.

[0029] According to the above technical solution, multiple fourteenth reinforcing ribs are provided on the rear wheel cover, and these multiple fourteenth reinforcing ribs are arranged around the rear wheel hub of the vehicle on the inner side of the rear side cover, that is, they are arranged in a roughly radial pattern with the rear wheel hub of the vehicle as the axis. This arrangement can improve the structural strength of the rear wheel cover area and resist the centripetal excitation from the wheel cover area.

[0030] Furthermore, the rear wheel arch is also provided with a fifteenth reinforcing rib group; the fifteenth reinforcing rib group is located on the outer side of the rear side panel, and the fifteenth reinforcing rib group includes multiple fifteenth reinforcing ribs, which surround the vehicle wheel arch and are spaced apart.

[0031] According to the above technical solution, multiple fifteenth reinforcing ribs are provided on the rear wheel arch, and these multiple fifteenth reinforcing ribs are arranged around the vehicle wheel arch on the outer side of the rear side panel, that is, arranged in a roughly radial pattern with the vehicle wheel arch as the center. This arrangement can improve the structural strength of the rear wheel arch area and improve the torsional performance of the rear area of ​​the vehicle.

[0032] Furthermore, the rear side panel also includes a side rear window, which is located on the rear side of the door; the second pillar is located on the rear side of the side rear window and adjacent to it, and the second pillar includes a C-pillar or a D-pillar; a sixteenth reinforcing rib group is provided on the C-pillar or D-pillar, the sixteenth reinforcing rib group is located on the outer side of the rear side panel, the sixteenth reinforcing rib group includes multiple sixteenth reinforcing ribs, the multiple sixteenth reinforcing ribs surround the side rear window and are spaced apart; and / or, a seventeenth reinforcing rib group is provided on the upper structure of the side rear window, the seventeenth reinforcing rib group is located on the outer side of the rear side panel, the seventeenth reinforcing rib group includes multiple seventeenth reinforcing ribs, the multiple seventeenth reinforcing ribs surround the side rear window and are spaced apart.

[0033] According to the above technical solution, the sixteenth and seventeenth reinforcing ribs are respectively set on the rear and upper sides of the side rear window. There are multiple sixteenth and seventeenth reinforcing ribs, which are arranged radially around the side rear window or in an array (single row). This can improve the structural strength of the side rear window area and enhance the torsional performance of the rear area of ​​the vehicle.

[0034] Furthermore, the rear side panel also includes an eighteenth reinforcing rib group and / or a nineteenth reinforcing rib group; the eighteenth reinforcing rib group is disposed on the outer side of the rear side panel, the eighteenth reinforcing rib group includes one or more eighteenth reinforcing ribs, the eighteenth reinforcing ribs are disposed on the C-pillar or D-pillar in the vertical direction, and intersect with multiple sixteenth reinforcing ribs; the nineteenth reinforcing rib group is disposed on the outer side of the rear side panel, the nineteenth reinforcing rib group includes one or more nineteenth reinforcing ribs, the nineteenth reinforcing ribs are disposed on the upper side of the side rear window in the front-rear direction, and intersect with multiple seventeenth reinforcing ribs.

[0035] According to the above technical solution, an eighteenth reinforcing rib and a nineteenth reinforcing rib are respectively provided on the rear and upper sides of the side rear window area. The eighteenth reinforcing rib intersects with multiple sixteenth reinforcing ribs and connects the multiple sixteenth reinforcing ribs into a whole. Similarly, the nineteenth reinforcing rib intersects with multiple seventeenth reinforcing ribs and connects the multiple seventeenth reinforcing ribs into a whole. This arrangement enables the vehicle to bear force as a whole among the multiple sixteenth reinforcing ribs and among the multiple seventeenth reinforcing ribs, improving the stability of the load-bearing structure. When the vehicle is traveling on bumpy roads, it can ensure the stability of the rear body in both the lateral and longitudinal directions.

[0036] Furthermore, the rear side enclosure also includes a tailgate mounting area, which is provided with a first mounting plate and a second mounting plate, which are spaced apart in the vertical direction; a vertically arranged support beam is provided between the first mounting plate and the second mounting plate.

[0037] According to the above technical solution, setting a first mounting plate and a second mounting plate on the tailgate mounting area facilitates the installation of the tailgate hinges. Furthermore, setting a support beam between the first and second mounting plates increases the bending and torsional stiffness of the tailgate mounting area, enabling it to better withstand the impact of forces during tailgate opening and closing.

[0038] Furthermore, the side panel body and the rear side panel are provided with multiple screw fastening parts.

[0039] According to the above technical solution, multiple screw-on fasteners can be installed, for example, in the A-pillar pillar area (for the installation of the A-pillar door hinge), the upper side panel area, the upper side beam, the B-pillar (for the installation of the B-pillar door hinge), and the tailgate mounting area (for the installation of the tailgate hinge). These multiple screw-on fasteners are formed simultaneously during the one-piece die-casting process of forming the vehicle side panel. By setting multiple screw-on fasteners, the rigidity of the mounting points of the final assembly parts can be improved. At the same time, assembly efficiency and accuracy can be improved, eliminating the need for additional reinforcing parts and inner panels, achieving lightweighting, and reducing weight and cost.

[0042] The beneficial effects of this invention are:

[0043] The vehicle side panel, body-in-white, and vehicle provided by this invention are manufactured using an integrated die-casting process to form the side panel body and rear side panel. The manufactured side panel body and rear side panel are a single, integral structure, formed in a single, single-step process. Compared to existing technologies that separately manufacture the side panel body and rear side panel components and then assemble them using welding or other methods, this invention eliminates the assembly and fixing process and time. Furthermore, it avoids the need for multiple separate steps and processes to manufacture individual components, saving equipment, processes, and time. Additionally, because the side panel body and rear side panel are an integral structure, there are no assembly errors caused by the connection and fixing of individual components. This allows for better assembly precision when assembling the vehicle side panel with other structural components of the vehicle. For the vehicle, the integrated structure of the side panel body and rear side panel enables better collision and torsional performance. Furthermore, the side panel body and rear side panel are manufactured using a one-piece die-casting method, typically using aluminum or aluminum alloys. Aluminum and aluminum alloys possess excellent corrosion and rust resistance; therefore, the overall structure of the side panel body and rear side panel does not require a surface coating for corrosion and rust prevention, eliminating the need for electrophoresis or spraying processes. Moreover, using aluminum for the entire vehicle side panel significantly reduces its weight compared to the ordinary steel used in existing technologies, thus contributing to a reduction in the overall vehicle weight. In addition, from a manufacturing process perspective, the production of the side panel body and rear side panel involves only a one-piece die-casting process, which can be performed on a single die-casting machine. The entire manufacturing process of the vehicle side panel eliminates the need for stamping and welding processes. For vehicle manufacturers, this reduces the need for stamping and welding equipment, allowing for a reduction in the size of stamping and welding workshops, thereby reducing manufacturing equipment and workshop space and ultimately significantly lowering costs.

Detailed Implementation

[0073] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0074] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0075] In one embodiment of the vehicle side panel provided by the present invention, such as Figures 1 to 3 and Figures 1 to 4 As shown, the vehicle side panel includes a side panel body 1 and a rear side panel 2, which are formed by integral die casting.

[0076] Specifically, the side panel body 1 refers to the entire side panel that roughly corresponds to the passenger compartment of the vehicle, excluding the parts corresponding to the engine compartment, front trunk, and rear trunk. Taking a typical four-door sedan as an example, the side panel body 1 includes all the pillars spaced apart along the front-rear direction, namely the A-pillar, B-pillar, and C-pillar, as well as the lower door sill and the upper side beam. Taking a typical four-door SUV as an example, the side panel body 1 includes the A-pillar, B-pillar, C-pillar, the lower door sill, and the upper side beam, but excludes the D-pillar.

[0077] Correspondingly, the rear side panel 2 refers to the portion of the entire side panel located behind the main body 1. Taking a typical four-door sedan as an example, the rear side panel 2 mainly includes the rear wheel arches. For a typical four-door SUV, the rear side panel 2, in addition to the rear wheel arches, also includes structures such as the D-pillar, and may also include the tailgate mounting structure.

[0078] It should be noted that, unless otherwise specified, the directions mentioned in this embodiment, such as front, back, up, and down, as well as the directions mentioned in the following description, such as left and right, are all based on the corresponding directions of the vehicle.

[0079] In this embodiment, the side panel body 1 and rear side panel 2 are formed by an integrated die-casting process. The prepared side panel body 1 and rear side panel 2 are an integral, one-piece structure; that is, including the A-pillar, B-pillar, C-pillar, as well as the door sill, upper side beam, and rear wheel arch, these components are a single integrated structure, which is formed in a single step. Compared with the prior art, which separately prepares each component of the side panel body 1 and rear side panel 2 and then assembles and fixes them by welding or other methods, this method saves the assembly and fixing process and time; moreover, it eliminates the need to prepare each component through multiple separate steps and processes, saving equipment, processes, and time.

[0080] In this embodiment, since the side panel body 1 and the rear side panel 2 are an integral structure, there are no assembly errors caused by the connection and fixation of various components. This allows for better assembly precision when assembling the vehicle side panel with other structural components of the vehicle. Furthermore, the integral structure of the side panel body 1 and the rear side panel 2 enables better torsional rigidity in a collision for the vehicle.

[0081] Furthermore, in this embodiment, the side panel body 1 and rear side panel 2 are formed by integral die casting, and the material used is generally aluminum or aluminum alloy. Aluminum and aluminum alloy have excellent corrosion and rust resistance; therefore, for the overall structure of the side panel body 1 and rear side panel 2, there is no need to cover the surface with a paint layer for corrosion and rust prevention, thus eliminating the need for electrophoresis or spraying processes. Moreover, the use of aluminum for the entire vehicle side panel, compared to the ordinary steel used in the prior art, can significantly reduce the weight of the vehicle side panel, thereby contributing to a reduction in the overall vehicle weight.

[0082] Furthermore, in terms of manufacturing processes, in this embodiment, the preparation of the side panel body 1 and the rear side panel 2 only involves an integrated die-casting process, which can be carried out on an integrated die-casting machine. Throughout the entire preparation process of the vehicle side panel, no stamping or welding processes are required. For vehicle manufacturers, adopting this embodiment reduces the need for stamping and welding equipment, thereby reducing the size of stamping and welding workshops, ultimately leading to a significant reduction in costs.

[0083] Furthermore, in existing methods for manufacturing vehicle side panels, the main body 1 and the rear side panel 2 are manufactured separately, and then assembled onto the vehicle body after each is completed. Whether using the traditional stamping process to manufacture individual parts or the newly emerging one-piece casting method (casting only a portion of the parts), the above path is followed. This is because, although both the main body 1 and the rear side panel 2 belong to the vehicle side panel category, they are located in different front and rear sections of the vehicle. Based on these differences, their functions within the overall vehicle and their ability to withstand external collision forces differ significantly. For the main body 1 and the rear side panel 2, the differences in their front-rear positions outweigh their shared characteristic as vehicle side panels. Therefore, existing technologies generally do not use a one-piece die-casting method to manufacture the main body 1 and the rear side panel 2 into a single unit.

[0084] This embodiment differs from the conventional approach and practice in the prior art. Based on and emphasizing the consistency of the side panel body 1 and the rear side panel 2 as vehicle side panels, they are manufactured into a single integral die-casting process. This allows for assembly onto the vehicle body as a whole, eliminating the need for separate assembly. Furthermore, reinforcing ribs can be strategically placed on the side panel body 1 and the rear side panel 2. These ribs are formed during the integral die-casting process, ensuring that the structural strength of the side panel body 1 and the rear side panel 2 meets the requirements.

[0085] In one embodiment of the vehicle side panel, the side panel body 1 includes a sill 11, an upper beam 12, and a plurality of first pillars 13 arranged along the front-rear direction of the vehicle; the plurality of first pillars 13 are located on the front and rear sides adjacent to the vehicle doors.

[0086] Specifically, in the vertical direction, the side panel 1 includes a sill 11 on the lower side and an upper beam 12 on the upper side. In the front-rear direction, the side panel 1 includes multiple first pillars 13, which are distributed on the front and rear sides of the vehicle door. That is, the side panel 1 encloses the vehicle door and roughly corresponds to the passenger compartment of the vehicle (except for two-door four-seat models and three-row SUVs, in which the passenger compartment is larger than the area enclosed by the side panel). The side panel 1 serves to protect the door and the passenger compartment.

[0087] In this embodiment, the multiple first pillars 13 may specifically include A-pillars, B-pillars, and, depending on the vehicle type, may also include C-pillars, etc. Taking ordinary four-door sedans and four-door SUVs as examples, the number of first pillars 13 is three, namely A-pillars, B-pillars, and C-pillars.

[0088] In one embodiment of the vehicle side panel, such as Figure 5 As shown, the plurality of first pillars 13 include an A-pillar 131; the A-pillar 131 includes a pillar area 1311; the pillar area 1311 of the A-pillar 131 is provided with a first reinforcing rib group and a second reinforcing rib group; the first reinforcing rib group includes a plurality of first reinforcing ribs J1, each first reinforcing rib J1 is arranged along the front-back direction, and the plurality of first reinforcing ribs J1 are spaced apart in the vertical direction; the second reinforcing rib group includes one or more second reinforcing ribs J2, the second reinforcing ribs J2 are arranged along the vertical direction and intersect with the plurality of first reinforcing ribs J1.

[0089] In this embodiment, the pillar area 1311 of the A-pillar 131 is the lower region of the A-pillar 131. A first reinforcing rib J1, arranged along the front-rear direction on the pillar area 1311 of the A-pillar 131, can resist impact forces from the front of the vehicle. A second reinforcing rib J2, arranged vertically, can connect multiple first reinforcing ribs J1 to form a mesh structure, improving the stability under stress and the upper limit of impact resistance, thereby better protecting the A-pillar 131, as well as the vehicle and its occupants.

[0090] In one embodiment of the vehicle side panel, the pillar area 1311 of the A-pillar 131 is further provided with a third reinforcing rib group, the third reinforcing rib group including a plurality of third reinforcing ribs J3, the third reinforcing ribs J3 being formed at the junction of the first reinforcing rib J1 and the second reinforcing rib J2; the dimension of the third reinforcing rib J3 in the front-rear direction is greater than the thickness of the second reinforcing rib J2, and the dimension in the vertical direction is greater than the thickness of the first reinforcing rib J1.

[0091] Within the column area 1311 of column A 131, the junction of the first reinforcing rib J1 and the second reinforcing rib J2 is a stress concentration area, which is prone to deformation and may lead to structural failure.

[0092] In this embodiment, a third reinforcing rib J3 is provided at the junction of the first reinforcing rib J1 and the second reinforcing rib J2. The third reinforcing rib J3 has a larger radial dimension, that is, it is thicker and thicker than the first reinforcing rib J1 and the second reinforcing rib J2. It can withstand greater impact forces, thereby effectively ensuring the transmission of forces in different directions and enhancing the performance of the first reinforcing rib group and the second reinforcing rib group in resisting external impact forces.

[0093] Specifically, the third reinforcing rib J3 can be a cylindrical structure with a diameter greater than the thickness of the first reinforcing rib J1 and the second reinforcing rib J2.

[0094] In one embodiment of the vehicle side panel, such as Figures 6 to 8 , Figure 9 As shown, the plurality of first pillars 13 include an A-pillar 131; the A-pillar 131 includes an upper enclosure 1312; the upper enclosure 1312 of the A-pillar 131 is provided with a fourth reinforcing rib group, a fifth reinforcing rib group, and a sixth reinforcing rib group; the fourth reinforcing rib group includes one or more fourth reinforcing ribs J4, which are arranged along the front-back direction and match the shape of the upper enclosure 1312 of the A-pillar; the fifth reinforcing rib group includes a plurality of fifth reinforcing ribs J5, each of which extends along the left-right direction and is spaced apart in the front-back direction; the sixth reinforcing rib group includes a sixth reinforcing rib J6, which is arranged along the front-back direction and is serrated or wavy, and each sixth reinforcing rib J6 connects between the fourth reinforcing ribs J4 and the fifth reinforcing ribs J5 and forms a triangular structure with the fourth reinforcing ribs J4 and the fifth reinforcing ribs J5.

[0095] In this embodiment, the upper surrounding area 1312 of the A-pillar 131 is the upper region of the A-area 131, which roughly corresponds to the window glass of the vehicle door. The upper surrounding area 1312 of the A-pillar 131 is generally a columnar structure with the upper end sloping backward. A fourth reinforcing rib J4 is provided on the upper surrounding area 1312 of the A-pillar 131. The fourth reinforcing rib J4 extends along the frontal direction and follows the shape of the upper surrounding area 1312, and can resist the impact force from the front of the vehicle. A fifth reinforcing rib J5 is provided on the upper surrounding area 1312 of the A-pillar 131, extending along the left-right direction, and can resist the impact force from the side of the vehicle. A sixth reinforcing rib J6, which is serrated or wavy, is provided on the upper side enclosure 1312 of the A-pillar 131. It connects with the fourth reinforcing rib J4 and the fifth reinforcing rib J5 to form a triangular structure, which can enhance the stability of the reinforcing rib structure in the upper side enclosure 1312 and ensure that the shape of the upper side enclosure 1312 does not deform, thereby effectively protecting the vehicle doors and passenger compartment during a vehicle collision.

[0096] In one embodiment of the vehicle side panel, such as Figure 10 As shown, the plurality of first pillars 13 include a B pillar 132; the B pillar 132 is provided with a seventh reinforcing rib group and an eighth reinforcing rib group; the seventh reinforcing rib group includes a plurality of seventh reinforcing ribs J7, each of the seventh reinforcing ribs J7 is arranged along the front-back direction, and the plurality of seventh reinforcing ribs J7 are spaced apart in the vertical direction; the eighth reinforcing rib group includes one or more eighth reinforcing ribs J8, the eighth reinforcing ribs J8 are arranged along the vertical direction and intersect with the plurality of seventh reinforcing ribs J7.

[0097] In this embodiment, the seventh reinforcing rib J7 arranged along the front-rear direction on the B-pillar 132 can resist the impact force from the side of the vehicle; the eighth reinforcing rib J8 arranged along the vertical direction can connect multiple seventh reinforcing ribs J7 to form a mesh structure, which improves the stability of the force and the upper limit of the impact force resistance. In the event of a collision, the force is distributed as a whole, avoiding local force concentration that may cause local breakage of the B-pillar 132, thereby better protecting the B-pillar 132, as well as the vehicle and its occupants.

[0098] In one embodiment of the vehicle side panel, such as Figure 4 and Figure 1As shown, the threshold 11 is provided with a ninth reinforcing rib group, a tenth reinforcing rib group, and an eleventh reinforcing rib group; the ninth reinforcing rib group includes one or more ninth reinforcing ribs J9, each ninth reinforcing rib J9 is arranged along the front-to-back direction, and the plurality of ninth reinforcing ribs J9 are spaced apart in the vertical direction; the tenth reinforcing rib group includes a plurality of tenth reinforcing ribs J10, each tenth reinforcing rib J10 is arranged obliquely downward in the front-to-back direction, and the plurality of tenth reinforcing ribs J10 are spaced apart in the front-to-back direction; the eleventh reinforcing rib group includes a plurality of eleventh reinforcing ribs J11, each eleventh reinforcing rib J11 is arranged obliquely upward in the front-to-back direction, and the plurality of eleventh reinforcing ribs J11 are spaced apart in the front-to-back direction; the ninth reinforcing ribs J9, tenth reinforcing ribs J10, and eleventh reinforcing ribs J11 intersect to form a triangular mesh structure.

[0099] In this embodiment, the ninth reinforcing rib J9, which is arranged in the front-rear direction within the sill 11, can resist the impact force from the front of the vehicle. The tenth and eleventh reinforcing ribs J10 and J11, which are arranged diagonally within the sill 11, can intersect with the ninth reinforcing rib J9 to form a triangular mesh structure. This mesh structure can improve the strength and stability of the reinforcing rib structure, enhance the resistance to frontal collision forces of the vehicle, and also resist collision forces from the side, thereby effectively protecting the vehicle doors and passenger compartment when a collision occurs.

[0100] In one embodiment of the vehicle side panel, such as Figure 2 As shown, the fourth reinforcing rib group extends rearward to the rear end of the upper beam 12; the upper beam 12 is provided with a twelfth reinforcing rib group and a thirteenth reinforcing rib group; the twelfth reinforcing rib group includes multiple twelfth reinforcing ribs J12, each of which extends in the left-right direction, and the multiple twelfth reinforcing ribs J12 are spaced apart in the front-back direction; the thirteenth reinforcing rib group includes a thirteenth reinforcing rib J13, which is arranged in the front-back direction and is serrated or wavy, and each thirteenth reinforcing rib J13 is connected between the fourth reinforcing rib J4 and the twelfth reinforcing rib J12 and forms a triangular structure with the fourth reinforcing rib J4 and the twelfth reinforcing rib J12.

[0101] In this embodiment, the fourth reinforcing rib J4, located on the upper side enclosure 1312 of the A-pillar 131, extends rearward to the rear end of the upper side beam 12. This fourth reinforcing rib J4, extending into the upper side beam 12, can also resist frontal impact forces. Furthermore, a twelfth reinforcing rib J12, extending laterally on the upper side beam 12, can resist side impact forces. A thirteenth reinforcing rib J13, shaped like a sawtooth or wave, is also located on the upper side beam 12. This thirteenth rib, connected to the fourth reinforcing rib J4 and the twelfth reinforcing rib J12, forms a triangular structure, enhancing the stability of the reinforcing rib structure in the upper side beam 12 and ensuring that the shape of the upper side beam 12 does not deform. This effectively protects the vehicle doors and passenger compartment during a collision.

[0102] In one embodiment of the vehicle side panel, see Figure 11 , Figure 11 as well as Figure 13 The rear side enclosure 2 includes a rear wheel arch 21 and a second pillar 22; the second pillar 22 is located on the rear side of the vehicle door and away from the door.

[0103] In this embodiment, the second pillar 22 differs from the aforementioned first pillar 13 in that it is not adjacent to the vehicle door. Generally, the second pillar 22 is located approximately at the rear of the vehicle, serving to bear loads and protect the vehicle's structure at the rear. A glass window, i.e., a side rear window, is also provided between the second pillar 22 and the door (i.e., between it and the last first pillar 13). The second pillar 22 is typically found on SUVs, MPVs, and station wagons, and is generally referred to as the D-pillar (the A, B, and C pillars are the first pillars 13).

[0104] In this embodiment, the rear side panel 2 includes a rear wheel cover 21 and a second pillar 22. That is, the rear wheel cover 21 and the second pillar 22 are formed synchronously with the aforementioned side panel body 1 in a single die-casting process and are an integral structure.

[0105] In other embodiments of the vehicle side panel, the rear side panel 2 may not include the second pillar 22, but retain the rear wheel arch 21. This is because some vehicle models do not inherently include the second pillar 22 in their structure. For example, in a typical four-door sedan, the A-pillar, B-pillar, and C-pillar are all part of the first pillar 13, not the second pillar 22. For vehicles with this structure, in actual implementation, the rear wheel arch 21 in the vehicle side panel can be implemented according to the arrangement of the rear wheel arch 21 in the above embodiments.

[0106] In one embodiment of the vehicle side panel, such as Figure 11As shown, the rear wheel arch 21 is provided with a fourteenth reinforcing rib group; the fourteenth reinforcing rib group is located on the inner side of the rear side enclosure 2, and the fourteenth reinforcing rib group includes a plurality of fourteenth reinforcing ribs J14, which surround the rear wheel hub of the vehicle and are spaced apart.

[0107] In this embodiment, a plurality of fourteenth reinforcing ribs J14 are provided on the rear wheel cover 21, and the plurality of fourteenth reinforcing ribs J14 are arranged around the rear wheel hub of the vehicle on the inner side of the rear side cover 2, that is, arranged in a roughly radial pattern with the rear wheel hub of the vehicle as the axis. This arrangement can improve the structural strength of the rear wheel cover 21 area and resist the centripetal excitation from the wheel cover area.

[0108] In one embodiment of the vehicle side panel, such as Figure 13 As shown, the rear wheel arch 21 is also provided with a fifteenth reinforcing rib group; the fifteenth reinforcing rib group is provided on the outside of the rear side enclosure 2, and the fifteenth reinforcing rib group includes a plurality of fifteenth reinforcing ribs J15, which surround the vehicle wheel arch and are spaced apart.

[0109] In this embodiment, a plurality of fifteenth reinforcing ribs J15 are provided on the rear wheel arch 21, and the plurality of fifteenth reinforcing ribs J15 are arranged around the vehicle wheel arch on the outer side of the rear side enclosure 2, that is, arranged in a roughly radial pattern with the vehicle wheel arch as the center. This arrangement can improve the structural strength of the rear wheel arch 21 area and improve the torsional performance of the rear area of ​​the vehicle.

[0110] In one embodiment of the vehicle side panel, such as Figure 13 and Figure 14 As shown, the rear side panel 2 also includes a side rear window 23, which is located on the rear side of the door; the second pillar 22 is located on the rear side of the side rear window 23 and adjacent to the side rear window 23, and the second pillar 22 includes a C-pillar or a D-pillar; a sixteenth reinforcing rib group is provided on the C-pillar or D-pillar, which is located on the outer side of the rear side panel 2, and includes multiple sixteenth reinforcing ribs J16, which surround the side rear window 23 and are spaced apart; a seventeenth reinforcing rib group is provided on the upper structure of the side rear window 23, which is located on the outer side of the rear side panel 2, and includes multiple seventeenth reinforcing ribs J17, which surround the side rear window 23 and are spaced apart.

[0111] In this embodiment, the vehicle side panel is specifically applied to models such as SUVs, MPVs, and station wagons, which generally have a side rear window 23 and a second pillar 22. In the common four-door vehicles of these models, the second pillar 22 is generally the D-pillar; while for the less common two-door vehicles, the second pillar 22 is generally the C-pillar.

[0112] In this embodiment, a sixteenth reinforcing rib J16 and a seventeenth reinforcing rib J17 are respectively provided on the rear and upper sides of the side rear window 23. There are multiple sixteenth reinforcing ribs J16 and seventeenth reinforcing ribs J17, which are arranged radially around the side rear window 23 or in an array (single row). This can improve the structural strength of the side rear window 23 area and enhance the torsional performance of the rear area of ​​the vehicle.

[0113] In other embodiments of the vehicle side panel, only the sixteenth reinforcing rib group or only the seventeenth reinforcing rib group can be provided. This arrangement can also improve the torsional performance of the rear area of ​​the vehicle and improve the structural strength of the side rear window 23 area, but it will be inferior to the aforementioned embodiment in which both the sixteenth and seventeenth reinforcing rib groups are provided.

[0114] In one embodiment of the vehicle side panel, such as Figure 15 As shown, the rear side panel 2 further includes an eighteenth reinforcing rib group and / or a nineteenth reinforcing rib group. The eighteenth reinforcing rib group is located on the outer side of the rear side panel 2, and includes one or more eighteenth reinforcing ribs J18. The eighteenth reinforcing ribs J18 are positioned vertically on the C-pillar or D-pillar and intersect with multiple sixteenth reinforcing ribs J16. The nineteenth reinforcing rib group is located on the outer side of the rear side panel 2, and includes one or more nineteenth reinforcing ribs J19. The nineteenth reinforcing ribs J19 are positioned longitudinally on the upper side of the rear side window 23 and intersect with multiple seventeenth reinforcing ribs J17.

[0115] In this embodiment, an eighteenth reinforcing rib J18 and a nineteenth reinforcing rib J19 are respectively provided on the rear and upper sides of the side rear window 23 area. The eighteenth reinforcing rib J18 intersects with multiple sixteenth reinforcing ribs J16, connecting the multiple sixteenth reinforcing ribs J16 into a whole. Similarly, the nineteenth reinforcing rib J19 intersects with multiple seventeenth reinforcing ribs J17, connecting the multiple seventeenth reinforcing ribs J17 into a whole. This arrangement enables the vehicle to bear force as a whole among the multiple sixteenth reinforcing ribs J16 and among the multiple seventeenth reinforcing ribs J17, improving the stability of the load-bearing structure. When the vehicle is traveling on bumpy roads, it can ensure the stability of the rear body in both the lateral and longitudinal directions.

[0116] In other embodiments of the vehicle side panel, only the eighteenth reinforcing rib group or only the nineteenth reinforcing rib group can be provided. This arrangement can also improve the stress stability of the rear body of the vehicle, but it will be inferior to the aforementioned embodiment in which both the eighteenth and nineteenth reinforcing rib groups are provided.

[0117] In the above embodiments of the vehicle side panel of the present invention, the first reinforcing rib J1 to the nineteenth reinforcing rib J19 are formed simultaneously by die casting during the integral die casting process of forming the vehicle side panel.

[0118] In one embodiment of the vehicle side panel, such as Figure 12 and Figure 14 As shown, the rear side enclosure 2 also includes a tailgate mounting area 24, which is provided with a first mounting plate 241 and a second mounting plate 242. The first mounting plate 241 and the second mounting plate 242 are spaced apart in the vertical direction. A vertically arranged support beam 243 is provided between the first mounting plate 241 and the second mounting plate 242.

[0119] In this embodiment, a first mounting plate 241 and a second mounting plate 242 are provided on the tailgate mounting area 24 to facilitate the installation of the tailgate hinge. A support beam 243 is provided between the first mounting plate 241 and the second mounting plate 242 to increase the bending and torsional stiffness of the tailgate mounting area 24, enabling it to better withstand the impact of forces during tailgate opening and closing.

[0120] In this embodiment, the first mounting plate 241, the second mounting plate 242, and the support beam 243 are die-cast simultaneously during the process of integrally die-casting to form the vehicle side panel.

[0121] In one embodiment of the vehicle side panel, such as Figure 15 and ​ , ​ As shown, the side body 1 and the rear side body 2 are provided with multiple screw fastening parts LJ.

[0122] Specifically, multiple threaded fasteners LJ can be provided, for example, in the pillar area 1311 of the A-pillar 131 (for the installation of the A-pillar door hinge), the upper side panel area 1312, the upper side beam 12, the B-pillar 132 (for the installation of the B-pillar door hinge), and the tailgate mounting area 24 (for the installation of the tailgate hinge), etc. These multiple threaded fasteners LJ are formed simultaneously during the integral die-casting process of forming the vehicle side panel.

[0123] In this embodiment, by setting multiple screw fasteners LJ, the rigidity of the mounting points of the final assembly parts can be improved. At the same time, the assembly efficiency and accuracy can be improved. There is no need to add reinforcing parts and inner plates, thus achieving lightweighting and reducing weight and cost.

[0124] In summary, the vehicle side panel provided in the above embodiments of the present invention is manufactured by an integrated die-casting process to form the side panel body 1 and the rear side panel 2. The manufactured side panel body 1 and the rear side panel 2 are an integral structure, and are manufactured in a single step. Compared with the prior art, which separately manufactures each component of the side panel body 1 and the rear side panel 2 and then assembles and fixes them by welding or other methods, this method saves the assembly and fixing process and time. Furthermore, it eliminates the need for multiple separate steps and processes to manufacture each component, saving equipment, processes, and time. In addition, since the side panel body 1 and the rear side panel 2 are an integral structure, there are no assembly errors caused by the connection and fixing of individual components. When assembling the vehicle side panel with other structural components of the vehicle, better assembly accuracy can be achieved. For the vehicle, the integral structure of the side panel body 1 and the rear side panel 2 can achieve better collision torsional performance. Furthermore, the side panel body 1 and rear side panel 2 are manufactured using a one-piece die casting method, typically using aluminum or aluminum alloys. Aluminum and aluminum alloys possess excellent corrosion and rust resistance; therefore, the overall structure of the side panel body 1 and rear side panel 2 does not require a surface coating for corrosion and rust prevention, eliminating the need for electrophoresis or spraying processes. Moreover, the use of aluminum for the entire vehicle side panel, compared to the ordinary steel used in existing technologies, significantly reduces the weight of the vehicle side panel, thus contributing to a reduction in overall vehicle weight. In addition, from a manufacturing process perspective, the production of the side panel body 1 and rear side panel 2 involves only a one-piece die casting process, which can be performed on a single die casting machine. The entire manufacturing process of the vehicle side panel eliminates the need for stamping and welding processes. For vehicle manufacturers, this reduces the need for stamping and welding equipment, allowing for a reduction in the size of stamping and welding workshops, thereby reducing manufacturing equipment and workshop space and ultimately significantly lowering costs.
