DETAILED DESCRIPTION

[0028] The preferred embodiments of the present application will be described in more detail below. Although the preferred embodiments of the present application are described below, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application is more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0029] As shown in Figures 1 to 4 The present application provides a side wall outer plate lower extension plate structure for connecting to the lower rear part of the side wall outer plate 12 of an automobile, comprising:

[0030] The plate body 1 has a pressure relief valve mounting hole 2 in the middle thereof, and a first connecting portion 3 and a second connecting portion 4 are respectively provided on the side of the upper end of the plate body 1 close to the front of the car and the side close to the rear of the car. The first connecting portion 3 and the second connecting portion 4 are respectively used to connect the lower rear portion of the side outer panel 12 and the taillight mounting plate 13 of the car, and the front end of the plate body 1 close to the front of the car and the rear end close to the rear of the car are respectively provided with a third connecting portion 5 and a fourth connecting portion 6. The third connecting portion 5 and the fourth connecting portion 6 are respectively used to connect the rear wheel cover panel 14 and the rear outer panel of the car.

[0031] Specifically, in order to solve the problems existing in the prior art, such as the unreasonable design of the lower extension plate structure of the side outer panel, which leads to the difficulty in designing and processing the side outer panel 12; the lower extension plate structure of the side outer panel provided by the utility model can connect the side outer panel 12, the rear wheel cover plate 14, the taillight mounting plate 13 and the rear outer panel of the automobile, play the role of connecting the side assembly and the rear assembly, and at the same time can provide an installation position for the pressure relief valve on the vehicle body, and the pressure relief valve can be installed in the pressure relief valve mounting hole 2 by directly embedding; at the upper end of its plate body 1, both the first connecting portion 3 and the second connecting portion 4 are provided, and the first connecting portion The second connecting portion 3 is arranged closer to the front and can be overlapped with the rear lower portion of the side panel outer panel 12 at the front upper portion of the panel body 1, so that the rear structure of the side panel outer panel 12 does not need to extend too much backward and downward, simplifying the structure of the side panel outer panel 12 and facilitating the molding and cost control of the side panel outer panel 12. The second connecting portion 4 is arranged closer to the rear and can be overlapped with the taillight mounting plate 13 at the rear upper portion of the panel body 1 through the second connecting portion 4, connecting both the side panel outer panel 12 and the taillight mounting plate 13 to the lower extension plate structure of the side panel outer panel, further simplifying the structure of the side panel outer panel 12 and the taillight mounting plate 13 and reducing the design difficulty of the side panel outer panel 12 and the taillight mounting plate 13.

[0032] Furthermore, the design of the first connection portion 3 and the second connection portion 4 at the upper end of the plate body 1 is more reasonable than the existing technology. The lower rear part of the side panel outer panel 12 is laterally overlapped with the first connection portion 3 of the front upper part of the plate body 1, reducing the sheet metal length and weight of the side panel outer panel 12 on the rear side, so that the overall stress state of the side panel structure is better; at the same time, the second connection portion 4 at the rear upper part of the plate body 1 is overlapped with the taillight mounting plate 13. Compared with the integrated side panel outer panel 12 and the taillight mounting plate 13, the plate body 1 that connects the two separately is not only simple in structure and easier to form, but also because the plate body 1 is an independent part and connects the side panel outer panel 12 and the taillight mounting plate 13 at the same time, the structural stability is also better, and it provides greater freedom for the forming of the taillight mounting plate 13; considering that the rear part of the side panel assembly is usually composed of the side panel outer panel 12, the taillight mounting plate 13 and the wheel arch outer panel and the structural distribution points are similar, the side panel outer panel lower extension plate structure is easy to use in a variety of vehicle models, easy to achieve universalization, and greatly reduce the cost of vehicle development.

[0033] In this embodiment, the first connection portion 3 , the second connection portion 4 , the third connection portion 5 and the fourth connection portion 6 are all overlapping edge structures.

[0034] Optionally, a stamping boss 7 is provided in the middle of the plate body 1 , and the pressure relief valve mounting hole 2 is opened on the stamping boss 7 .

[0035] Specifically, the arrangement of the stamping boss 7 can strengthen the structure of the plate body 1 and provide a flow space for the installation of the pressure relief valve.

[0036] Optionally, the pressure relief valve mounting hole 2 is rectangular, and the long side direction of the pressure relief valve mounting hole 2 is the direction from the front to the rear of the car.

[0037] Specifically, the pressure relief valve mounting hole 2 is in the shape of a long strip along the front-rear direction of the automobile, and the pressure relief valve is embedded in the mounting hole 2, forming a transverse mounting layout of the pressure relief valve.

[0038] Optionally, the stamped boss 7 protrudes toward the interior of the vehicle.

[0039] Specifically, when the side outer panel lower extension plate structure is installed on the body of the car, the stamped boss 7 protrudes toward the interior of the car and appears concave when viewed from outside the car.

[0040] Optionally, the first connection portion 3 is inclined downward from the back to the front, and the first connection portion 3 and the second connection portion 4 form a pointed structure.

[0041] Specifically, the first connecting part 3 and the second connecting part 4 are located at the edge of the plate body 1 and are both in the shape of long strips. The rear end of the first connecting part 3 is connected to the front end of the second connecting part 4, and the two form an upward pointed structure as a whole, so that the upper part of the plate body 1 forms a triangular structure with the pointed corner facing upward.

[0042] In this embodiment, the first connecting portion 3 and the second connecting portion 4 are formed by stamping, and a stamping portion with an S-shaped cross section is formed at the root position thereof, which can improve the overall structural strength of the plate body 1.

[0043] Optionally, the plate body 1 is provided with a positioning hole 8 .

[0044] Specifically, the positioning holes 8 are used to fix the plate body 1 when the plate body 1 is subjected to sheet metal stamping.

[0045] In this embodiment, one positioning hole 8 is provided.

[0046] Optionally, the third connecting portion 5 is inclined downward from front to back.

[0047] Specifically, the third connecting portion 5 is obliquely arranged at the front lower portion of the plate body 1 for overlapping with the rear wheel housing panel 14 of the automobile.

[0048] In this embodiment, the front end of the third connecting portion 5 is close to the front end of the first connecting portion 3, forming a triangular structure at the front end of the plate body 1 with the tip facing the vehicle head; Figure 5 As shown, the front end of the third connecting portion 5 is integrally connected to the front end of the first connecting portion 3 via an arc-shaped transition structure 9, which is easier to stamp and form.

[0049] Furthermore, the positioning hole 8 is arranged on the outside of the stamping boss 7 and is closer to the front of the vehicle than the stamping boss 7. The stamping boss 7 is located in a triangular structure formed at the front end of the plate body 1 with the tip facing the front of the vehicle. The positioning hole 8 is formed on the circular boss. The setting of the circular boss can further improve the structural strength here.

[0050] Optionally, the fourth connecting portion 6 is a flange provided at the rear end of the plate body 1 , and the flange is bent toward the interior of the car.

[0051] Specifically, the fourth connecting portion 6 is formed by a bent flange at the rear end of the plate body 1. When the lower extension plate structure of the side outer panel is installed on the vehicle body, the flange is bent toward the inside of the vehicle, leaving space for the overlap of the rear outer panel, thereby improving the structural strength of the plate body 1 and facilitating connection with the rear outer panel.

[0052] In this embodiment, the fourth connecting portion 6 is in the shape of a vertically extending long strip.

[0053] In this embodiment, a first bending portion 10 bent toward the interior of the vehicle is provided at the lower end of the plate body 1, and the fourth connecting portion 6 is formed at an end of the first bending portion 10 close to the front of the vehicle; a second bending portion 11 is provided below the first bending portion 10 in a bending direction opposite to the first bending portion 10, and the second bending portion 11 includes a plurality of profiles arranged in a folded line from front to back.

[0054] Optionally, the lower extension plate structure of the side outer panel is an integrally formed structure, and its material is DC04 steel.

[0055] Specifically, the lower extension plate structure of the side outer panel uses DC04 steel as raw material. Through the above-mentioned structural design of the plate body 1, it can meet the standard requirements even if it uses DC04 steel with a not very high yield strength, and can also meet the rigidity requirements of the vehicle structure. In addition, the space utilization rate of the above-mentioned structural design is also high, and the pressure relief valve can be fully lowered to leave sufficient space for the wheel arch inner panel.

[0056] In this embodiment, the thickness of the plate body 1 is 0.7mm, and the overall weight is only 0.763Kg. Compared with the side outer panel lower extension plate of other models, which usually weighs 0.8Kg-1Kg and is 0.8mm thick, the side outer panel lower extension plate structure reduces weight by nearly 20%. At the same time, the above-mentioned structural design enables it to use fewer stamping times in molding to control costs.

[0057] like Figure 6 and Figure 7 As shown, the present invention also provides an automobile, comprising the above-mentioned side outer panel lower extension plate structure;

[0058] The first connection portion 3 and the second connection portion 4 of the lower extension plate structure of the side outer panel are respectively connected in an overlapping manner to the lower rear edge of the side outer panel 12 and the lower side edge of the taillight mounting plate 13, and the third connection portion 5 and the fourth connection portion 6 of the lower extension plate structure of the side outer panel are respectively connected in an overlapping manner to the rear edge of the rear wheel cover plate 14 and the end of the rear outer panel.

[0059] Specifically, the above-mentioned side outer panel lower extension plate structure connects the side outer panel 12, rear wheel cover panel 14, taillight mounting plate 13 and rear outer panel of the car, plays the role of connecting the side assembly and the rear assembly, and at the same time provides an installation position for the pressure relief valve on the car body. The pressure relief valve can be installed in the pressure relief valve mounting hole 2 by direct embedding.

[0060] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
