Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and in particular to a vehicle body side panel. Furthermore, this invention also relates to a vehicle having the aforementioned side panel. Background Technology

[0002] The side panel is a crucial component of a car's body structure, typically comprising an outer side panel, a reinforcing side panel, and an inner side panel. During stamping, these components are manufactured separately and then welded together to form the side panel. However, due to the limitations of existing side panel structures, the various parts, especially the outer side panel, are quite complex, leading to high development costs for stamping dies. Furthermore, existing side panels are generally heavy, hindering lightweight vehicle design. Summary of the Invention

[0003] In view of this, the present invention aims to provide a vehicle body side panel that simplifies the structure of the side panel outer panel and reduces the weight of the vehicle body side panel.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A vehicle body side panel includes an inner side panel unit and an outer side panel unit, as well as a decorative element extending along the front-rear direction of the vehicle; the inner side panel unit is composed of an inner side panel; the outer side panel unit has a side panel reinforcement plate and a side panel outer panel spliced ​​together, and the side panel outer panel is connected to the rear lower part of the side panel reinforcement plate, and the decorative element is disposed at the top of the side panel reinforcement plate.

[0006] Furthermore, the side reinforcement plate includes a front section of the upper beam reinforcement plate, a sill beam reinforcement plate, a column reinforcement unit connecting the front section of the upper beam reinforcement plate and the sill beam reinforcement plate, and a rear corner window reinforcement plate connected to the rear end of the front section of the upper beam reinforcement plate.

[0007] The column reinforcement unit includes at least an A-column reinforcement plate and a B-column reinforcement plate.

[0008] Furthermore, the outer side panel is located below the rear corner window reinforcing plate;

[0009] The front end of the side panel extends toward the decorative element and is connected to the rear end of the sill beam reinforcement plate. The top end of the side panel is connected to the rear corner window reinforcement plate.

[0010] Furthermore, the top of the rear corner window reinforcing plate has a rear section of an upper side beam reinforcing plate, which is connected to the front section of the upper side beam reinforcing plate.

[0011] Furthermore, the decorative element is connected to the outer side of the front section and the rear section of the upper beam reinforcing plate.

[0012] Furthermore, the decorative element is made of plastic or carbon fiber material.

[0013] Furthermore, the side panel includes a main body, a connecting portion located at the front end of the main body, and a mounting portion located at the rear end of the main body;

[0014] The connecting portion extends forward and downward and is connected to the rear end of the sill beam reinforcement plate. The mounting portion is provided with a rear bumper bracket mounting part.

[0015] Furthermore, the rear end of the threshold beam reinforcing plate is connected to a rearwardly extending connecting plate, which overlaps with and is connected to the front end of the connecting portion.

[0016] Furthermore, the A-pillar reinforcement plate, the B-pillar reinforcement plate, and the sill beam reinforcement plate are integrally formed.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The vehicle side panel of the present invention, by having the outer side panel and the side panel reinforcement plate together form an outer panel unit, and by connecting the outer side panel to the rear lower part of the side panel reinforcement plate, allows the side panel reinforcement plate to replace the non-appearance area of ​​the existing outer side panel, which simplifies the structure of the outer side panel, reduces the development and manufacturing cost of the outer side panel stamping die, and at the same time helps to reduce the weight of the vehicle side panel, making it easier to achieve lightweight vehicle design. Furthermore, by providing a decorative part at the top of the side panel reinforcement plate, the aesthetics of the vehicle side panel are enhanced.

[0019] Furthermore, by including the front section of the upper beam reinforcement plate, the sill beam reinforcement plate, the column reinforcement unit, and the rear corner window reinforcement plate in the side wall reinforcement plate, it is beneficial to improve the structural strength of the upper beam, sill beam, rear corner window, and A-column and B-column positions, and it is also convenient to realize that the side wall reinforcement plate and the side wall outer plate together form the outer panel unit.

[0020] In addition, by connecting the front end of the side panel to the rear end of the sill beam reinforcement plate and the top end of the side panel to the rear corner window reinforcement plate, it is beneficial to make the side panel and the side reinforcement plate together form an outer panel unit, while making the structure of the side panel simpler.

[0021] Secondly, by setting the rear section of the upper beam reinforcement plate on the rear corner window reinforcement plate, the front and rear sections of the upper beam reinforcement plate can be manufactured separately, resulting in a simple structure that is easy to stamp and form. At the same time, setting the rear section of the upper beam reinforcement plate on the rear corner window reinforcement plate also facilitates the connection between the upper beam reinforcement plate and the corner window reinforcement plate.

[0022] Furthermore, by making the trim pieces from carbon fiber or plastic, it is easier to make them lighter, which facilitates the lightweight design of the vehicle.

[0023] Furthermore, by including both connecting and mounting portions in the side panel, the connection between the sill beam reinforcement plate and the rear bumper bracket and the side panel is facilitated. Additionally, the presence of a connecting plate on the sill beam reinforcement plate that connects to the connecting portion enhances the connection strength between the sill beam reinforcement plate and the side panel.

[0024] In addition, by molding the A-pillar reinforcement plate, B-pillar reinforcement plate, and sill beam reinforcement plate into a single piece, the production process can be simplified, and it is also beneficial to give it better structural strength.

[0025] Another object of the present invention is to provide a vehicle having a body side panel as described above.

[0026] The vehicle described in this invention, by having the side panels as described above, helps to reduce vehicle production costs and facilitates lightweight vehicle design. Attached Figure Description

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] This embodiment relates to a vehicle side panel. In terms of overall structure, the side panel includes an inner panel unit and an outer panel unit, as well as a decorative element 4 extending along the front-rear direction of the vehicle. The inner panel unit is composed of an inner side panel 1, and the outer panel unit has a side panel reinforcing plate 2 and an outer side panel 3 spliced ​​together. The outer side panel 3 is connected to the lower rear of the side panel reinforcing plate 2, and the decorative element 4 is located at the top of the side panel reinforcing plate 2.

[0043] It is understood that in this embodiment, by having the outer side panel 3 and the side reinforcement plate 2 together form an outer side panel unit, and by connecting the outer side panel 3 to the rear lower part of the side reinforcement plate 2, the side reinforcement plate 2 can replace the non-appearance area of ​​the existing outer side panel, which simplifies the structure of the outer side panel 3, reduces its development and manufacturing costs, and at the same time helps to reduce the weight of the vehicle side panel, making it easier to achieve lightweight vehicle design. Furthermore, by providing a decorative piece 4 at the top of the side reinforcement plate 2, the aesthetics of the vehicle side panel are improved.

[0044] It should be noted that the structure of the inner side panel 1 in this embodiment can be designed with reference to the structure of the inner side panel on existing vehicles, and will not be described in detail here.

[0045] Based on the above overall description, an exemplary structure of this embodiment is as follows: Figures 1 to 7 As shown in the figure. Furthermore, as a preferred embodiment, as... Figure 1 and Figure 2 As shown in the illustration, in this embodiment, the side reinforcement plate 2 includes a front section 201 of the upper beam reinforcement plate, a sill beam reinforcement plate 202, a column reinforcement unit connecting the front section 201 of the upper beam reinforcement plate and the sill beam reinforcement plate 202, and a rear corner window reinforcement plate 203 connected to the rear end of the front section 201 of the upper beam reinforcement plate. The column reinforcement unit includes an A-pillar reinforcement plate 204 and a B-pillar reinforcement plate 205.

[0046] By including the front section 201 of the upper beam reinforcement plate, the sill beam reinforcement plate 202, the column reinforcement unit, and the rear corner window reinforcement plate 203 in the side wall reinforcement plate 2, and by including the A-pillar reinforcement plate 204 and the B-pillar reinforcement plate 205 in the column reinforcement unit, it is beneficial to improve the structural strength of the upper beam, sill beam, rear corner window, and the A-pillar and B-pillar positions, and it is also convenient to realize that the side wall reinforcement plate 2 and the aforementioned side wall outer plate 3 together constitute the outer panel unit.

[0047] Furthermore, since the side wall outer panel 3 is no longer provided on the outside of the side wall reinforcement panel 2, the dimensions of the aforementioned upper beam reinforcement panel front section 201, sill beam reinforcement panel 202, column reinforcement unit, and rear corner window reinforcement panel 203 can be appropriately increased within the allowable range. Especially for the upper beam area with a smaller cross section, after removing the side wall outer panel 3 located on its outside, the upper beam reinforcement panel can occupy the space originally occupied by the side wall outer panel, thereby appropriately increasing the cross-sectional dimensions of the upper beam reinforcement panel to improve its structural strength.

[0048] Of course, this is not limited to the upper beam area. In specific implementations, the cross-sectional dimensions of other reinforcing plates can also be appropriately increased. In addition, while appropriately increasing the cross-sectional dimensions of each reinforcing plate constituting the side reinforcement plate 2, the thickness of each reinforcing plate can be appropriately reduced to facilitate the lightweight design of the vehicle.

[0049] It should be noted that in this embodiment, the pillar reinforcement unit only includes the A-pillar reinforcement plate 204 and the B-pillar reinforcement plate 205 as a preferred implementation. Furthermore, when the vehicle with this side panel has a C-pillar, or has both a C-pillar and a D-pillar, the pillar reinforcement unit can correspondingly include the A-pillar reinforcement plate 204, the B-pillar reinforcement plate 205, and the C-pillar reinforcement plate, or it can include the A-pillar reinforcement plate 204, the B-pillar reinforcement plate 205, the C-pillar reinforcement plate, and the D-pillar reinforcement plate. Additionally, the pillar reinforcement unit and the front section 201 of the upper beam reinforcement plate can be connected using methods commonly used in the prior art, such as spot welding or arc welding.

[0050] In specific implementation, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the cross-sections of the A-pillar reinforcement plate 204, the B-pillar reinforcement plate 205, and the sill beam reinforcement plate 202 can all be arched outwards, and the cross-section of the sill beam reinforcement plate 202 can also be arched upwards. In this way, a cavity can be formed between the side reinforcement plate 2 and the inner side panel 1, so as to further improve the structural strength of the vehicle side panel.

[0051] As a superior arrangement method, such as Figure 2 As shown in the figure, in this embodiment, the side outer panel 3 is located below the rear corner window reinforcement plate 203, and the front end of the side outer panel 3 extends towards the decorative piece 4 and is connected to the rear end of the sill beam reinforcement plate 202. The top end of the side outer panel 3 is connected to the rear corner window reinforcement plate 203.

[0052] Understandably, by connecting the front end of the side panel 3 to the rear end of the sill beam reinforcement plate 202, and connecting the top end of the side panel 3 to the rear corner window reinforcement plate 203, it is beneficial for the side panel 3 and the side reinforcement plate 2 to jointly form an outer panel unit, while also simplifying the structure of the side panel 3. In specific implementation, the side panel 3 and the sill beam reinforcement plate 202, as well as the side panel 3 and the rear corner window reinforcement plate 203, can be connected by electric welding or arc welding.

[0053] In addition, as Figure 2 As shown, the rear corner window reinforcing plate 203 has a rear section 2031 of the upper side beam reinforcing plate at its top, which is connected to the front section 201 of the upper side beam reinforcing plate. In specific implementations, the front section 201 and the rear section 2031 of the upper side beam reinforcing plate can also be connected by spot welding or arc welding, which are commonly used in the prior art.

[0054] In addition, by setting the rear section 2031 of the upper beam reinforcing plate on the rear corner window reinforcing plate 203, the upper beam reinforcing plate is made into a front section and a rear section separately, which facilitates stamping and forming. At the same time, the rear section 2031 of the upper beam reinforcing plate set on the rear corner window reinforcing plate 203 can also facilitate the connection between the upper beam reinforcing plate and the rear corner window reinforcing plate 203.

[0055] As a further preferred embodiment, the decorative element 4 is connected to the outer side of the front section 201 and the rear section 2031 of the upper beam reinforcing plate. In specific implementation, such as... Figure 2 and Figure 4 As shown, the decorative piece 4 is attached above the front section 201 and the rear section 2031 of the upper beam reinforcing plate. With this arrangement, the decorative piece 4 can cover the connection position between the front section 201 and the rear section 2031 of the upper beam reinforcing plate, so that only the reliability of the connection position needs to be ensured, without having to ensure the exquisiteness of the connection position, which facilitates the connection operation between the front section 201 and the rear section 2031 of the upper beam reinforcing plate.

[0056] As a preferred embodiment, the decorative element 4 in this embodiment can be made of carbon fiber material, so that the decorative element 4 has good strength and corrosion resistance while being lightweight. Of course, making the decorative element 4 of carbon fiber material is only a preferred embodiment; in addition, the decorative element 4 can also be made of plastic.

[0057] In addition, such as Figure 2 As shown in the figure, in this embodiment, the side panel 3 includes a main body portion 301, a connecting portion 302 located at the front end of the main body portion 301, and a mounting portion 303 located at the rear end of the main body portion 301. The connecting portion 302 extends forward and downward and is connected to the rear end of the sill beam reinforcement plate 202. The mounting portion 303 is provided with a rear bumper bracket mounting part.

[0058] It is understood that the connection portion 302 facilitates the connection between the sill beam reinforcement plate 202 and the side outer panel 3, and the mounting portion 303 facilitates the connection between the rear bumper bracket and the side outer panel 3. In specific implementations, the rear bumper bracket mounting portion can be set with reference to the existing connection structure between the rear bumper bracket and the vehicle body, and will not be described in detail here. In addition, the side outer panel 3 in this embodiment can preferably be made of aluminum alloy by stamping, which is convenient for pressing and has a lower cost.

[0059] In addition, as a preferred option, such as Figure 1 and Figure 7As shown in the illustration, in this embodiment, a rearwardly extending connecting plate 5 is connected to the rear end of the sill beam reinforcing plate 202. The connecting plate 5 overlaps with and is connected to the front end of the connecting portion 302. It can be understood that by providing the connecting plate 5, the connection strength between the sill beam reinforcing plate 202 and the side panel 3 is improved.

[0060] As a preferred implementation, in this embodiment, the A-pillar reinforcing plate 204, the B-pillar reinforcing plate 205, and the sill beam reinforcing plate 202 are integrally formed. Thus, after the A-pillar reinforcing plate 204, the B-pillar reinforcing plate 205, and the sill beam reinforcing plate 202 are stamped, there is no need to connect the parts, which simplifies the production process and also gives it better structural strength.

[0061] In this embodiment, the vehicle side panel, by having the outer side panel 3 and the side panel reinforcing plate 2 together form an outer panel unit, and by connecting the outer side panel 3 to the lower rear of the side panel reinforcing plate 2, simplifies the structure of the outer side panel 3, reduces its development and manufacturing costs, and also reduces the weight of the vehicle side panel, facilitating lightweight vehicle design. Furthermore, by including a main body portion 301, a connecting portion 302, and a mounting portion 303 in the outer side panel 3, the structure is simple, facilitating connection with the side panel reinforcing plate 2 and simplifying the installation of the rear bumper bracket.

[0064] The vehicle in this embodiment, by having the body side panel of Embodiment 1, helps to reduce the production cost of the vehicle and facilitates the lightweight design of the vehicle.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
