[0002] In vehicle styling design, the fastback styling of the rear door is favored by the market because of its outstanding visual beauty and compliance with aerodynamic design. The design of integrating a high-mounted brake light and a taillight on the rear door of models such as SUVs also has excellent lighting effects. In the related prior art, the high-mounted brake light is integrated on the spoiler and installed on the outer top area of the rear door through the spoiler, while the taillight is installed at the lower position of the rear windshield. Among them, the setting of integrating the high-mounted brake light on the spoiler will affect the fastback styling design, such as affecting the through-transition design between the rear door and the roof panel. For the taillight, the inner panel of the rear door needs to be formed with corresponding installation structures. Due to the large size of the fastback-designed rear door along the longitudinal direction of the vehicle body, it is difficult to further form the taillight installation structure on the inner panel, and it is easy to affect the support strength of the rear windshield. Therefore, it is necessary to redesign an installation scheme for the high-mounted brake light and the taillight for the fastback rear door. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. To this end, in a first aspect, the utility model provides a rear door, which can install a high-mounted brake light without setting a spoiler and reduce the forming difficulty of the taillight installation base, and is applicable to the fastback styling.

[0007] The rear door according to the embodiment of the present utility model has at least the following beneficial effects: In the rear door of this embodiment, a tail light mounting plate is spliced on the inner panel, and the tail light mounting plate is used to provide a basis for mounting the tail light. Compared with the method of directly stamping and forming the tail light mounting on the inner panel, it can effectively reduce the stamping depth, thereby improving the forming quality and ensuring the structural strength of the rear door, and further ensuring the support strength of the rear windshield, and can solve the problems of large stamping depth and difficult forming in the fastback styling; at the same time, the hinge reinforcing plate extends to the installation window of the rear windshield to provide a mounting position for the high-mounted brake light, and the high-mounted brake light can be integrated inside the rear windshield, without the need to set up a spoiler for mounting the high-mounted brake light. Therefore, this embodiment can effectively solve the problems of mounting the high-mounted brake light and the tail light in the fastback styling, and while realizing the mounting of the high-mounted brake light and the tail light, it can ensure the forming quality and structural strength, and further ensure the support strength of the rear windshield.

[0008] It can be understood that, compared with the large-sized inner panel, the size of the tail light mounting plate is smaller, which is beneficial to forming various complex shapes or curved surfaces, so there are more design possibilities, more design schemes can be realized, and the mounting hole positions of the tail light mounting plate are no longer restricted by the forming of the inner panel during forming, and the direction and position of the mounting hole positions can be flexibly designed according to needs, so as to improve the convenience of vehicle assembly and the disassembly and replacement efficiency of later maintenance and repair.

[0009] According to some embodiments of the present utility model, the hinge reinforcing plate is provided with reinforcing ribs along at least two directions, and the reinforcing ribs in different directions intersect with each other. Thus, it is beneficial to improve the torsional stiffness and mode of the hinge reinforcing plate.

[0010] According to some embodiments of the present utility model, at least one of the reinforcing ribs extends downward from a position close to the hinge to a position close to the extension part. Thus, it is beneficial to improve the structural strength of the extension part, and further ensure the mounting stability of the high-mounted brake light.

[0012] According to some embodiments of the present utility model, the hinge reinforcing plate extends from above the installation window to the left and / or right side of the installation window. Thus, the structural strength of the upper and side areas of the installation window can be strengthened through the hinge reinforcing plate, improving the structural strength of the rear door, and further ensuring the support strength for the rear windshield.

[0013] According to some embodiments of the present utility model, the rear door further includes a strut reinforcement plate, and the strut reinforcement plate is disposed in the installation space and connected to the taillight mounting plate. Thus, the strut reinforcement plate can be used to improve the structural strength of the taillight mounting plate.

[0014] According to some embodiments of the present utility model, the strut reinforcement plate extends out of the installation space from the edge of the first window and is connected to the left and right ends of the taillight mounting plate. The strut reinforcement plate is provided with a lapping edge between the edge of the first window and the edge of the taillight mounting plate, and the lapping edge is connected to the edge of the second window for cooperating with the inner plate, the taillight mounting plate and the outer plate to define the installation window. Thus, on one hand, the strut reinforcement plate is used to reduce the stamping depth of the inner plate, improve the forming quality and structural strength of the inner plate, and on the other hand, the structural strength and support strength of the taillight mounting plate can be improved.

[0015] According to some embodiments of the present utility model, the strut reinforcement plate extends upward on the side of the installation window to connect to the hinge reinforcement plate. Thus, the strut reinforcement plate and the hinge reinforcement plate are used to improve the structural strength on both sides of the installation window, and further ensure the support strength for the rear windshield.

[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0036] In the description of the present utility model, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, etc., it is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

If there is a description of the first and the second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0038] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0039] In vehicle styling design, the fastback styling of the rear door is favored by the market because of its outstanding visual beauty and compliance with aerodynamic design. The design of integrating a high-mounted brake light and a taillight on the rear door of models such as SUVs also has excellent lighting effects. In the relevant prior art, the high-mounted brake light is integrated on the spoiler and installed on the outer top area of the rear door through the spoiler, while the taillight is installed at the lower position of the rear windshield. Among them, the setting of integrating the high-mounted brake light on the spoiler will affect the design of the fastback styling, such as affecting the through-transition design between the rear door and the roof panel. For the taillight, the inner panel of the rear door needs to be formed with a corresponding installation structure. Since the rear door with a fastback design has a relatively large size along the longitudinal direction of the vehicle body, it is difficult to further form the taillight installation structure on the inner panel, and it is easy to affect the support strength of the rear windshield. Therefore, it is necessary to redesign an installation scheme for the high-mounted brake light and the taillight for the fastback rear door.

[0040] The present utility model provides a rear door that can install a high-mounted brake light without setting a spoiler and reduce the forming difficulty of taillight installation, and is applicable to the fastback styling.

[0041] Refer to Figures 1 to 5, the rear door of an embodiment of the present utility model includes an inner panel 100, a tail light mounting plate 400, an outer panel 200, and a hinge reinforcement plate 300. The inner panel 100 is provided with a first window 101. The tail light mounting plate 400 overlaps the lower edge of the first window 101 and is fixedly connected to the inner panel 100. The tail light mounting plate 400 is formed with a mounting structure matching the tail light for mounting the tail light. The first window 101 forms a first overlapping area through the edge of the tail light mounting plate 400. It can be understood that the first overlapping area is an annular edge area formed by connecting the edge of the first window 101 not connected to the tail light mounting plate 400 and the edge of the tail light mounting plate 400. A second window 201 is provided on the outer panel 200. The edge of the second window 201 overlaps and is fixedly connected to the first overlapping area, thereby jointly defining an installation window for the rear windshield with the inner panel 100 and the tail light mounting plate 400. The outer panel 200 is fixedly connected to the outer peripheral side of the inner panel 100, and the outer panel 200 and the inner panel 100 maintain a distance at least in part, thereby forming an installation space therebetween. The hinge reinforcement plate 300 is disposed in the installation space, and the hinge reinforcement plate 300 has an extension 301 extending to the installation window. The extension 301 is provided with a mounting structure matching the high-mounted brake light for mounting the high-mounted brake light.

[0042] It can be understood that the tail light mounting plate 400 in this embodiment is connected to the lower edge of the first window 101. Therefore, when installing the tail light, the tail light is in the bottom area of the installation window, while the hinge reinforcement plate 300 is disposed in the upper area of the rear door for structurally strengthening the hinge installation area of the rear door. Therefore, there is no interference between the two, and the installation of the high-mounted brake light and the tail light can be achieved simultaneously. Moreover, the edge of the tail light mounting plate 400 is directly connected to the edge of the outer panel 200 to jointly define the installation window for the rear windshield. That is, the tail light mounting plate 400 is equivalent to a part disassembled from the traditional inner panel 100. When connecting the lower edge of the first window 101, it can be regarded as an independently formed extended side wall on the inner panel 100.

[0043] Therefore, in the rear door of this embodiment, the tail light mounting plate 400 is spliced on the inner panel 100, and the tail light mounting plate 400 is used to provide a basis for tail light installation. Compared with the method of directly stamping and forming the tail light installation on the inner panel 100, it can effectively reduce the stamping depth of the inner panel 100, improve the forming quality of the inner panel 100 and the tail light installation part, ensure the structural strength of the rear door, and further ensure the support strength of the rear windshield. It can solve the problems of large stamping depth and difficult forming in the fastback styling when applied to the fastback styling.

[0044] Meanwhile, in this embodiment, the hinge reinforcement plate 300 extends to the installation window of the rear windshield to provide an installation position for the high-mounted brake light. The high-mounted brake light can be integrated inside the rear windshield, eliminating the need to set up a spoiler for installing the high-mounted brake light, and thus not affecting the design of the fastback rear door.

[0045] Therefore, this embodiment can effectively solve the installation problems of the high-mounted brake light and taillight for the fastback styling. While achieving the installation of the high-mounted brake light and taillight, it can ensure the molding quality and structural strength, and further ensure the support strength of the rear windshield.

[0046] Furthermore, it can be understood that compared with the large inner panel 100, the taillight mounting plate 400 is smaller in size, which is beneficial for forming various complex shapes or curved surfaces. Therefore, it has more design possibilities, can implement more design schemes, and the mounting hole positions of the taillight mounting plate 400 are no longer restricted by the molding of the inner panel 100 during molding. The direction and position of the mounting hole positions can be flexibly designed according to needs, so as to improve the convenience of vehicle assembly and the disassembly efficiency of later maintenance and repair.

[0047] Refer to Figure 7 , in some embodiments of the present invention, the hinge reinforcement plate 300 intersects with a first reinforcing rib 302 and a second reinforcing rib 303. The first reinforcing rib 302 and the second reinforcing rib 303. And the first reinforcing rib 302 and the second reinforcing rib 303 penetrate through the hinge reinforcement plate 300 along their own length directions. The penetration in this embodiment means that the reinforcing ribs extend to the ends of the hinge reinforcement plate 300 along their own length directions, rather than penetrating through the hinge reinforcement plate 300 in the thickness direction of the hinge reinforcement plate 300. By cross-setting the first reinforcing rib 302 and the second reinforcing rib 303 in this embodiment, the torsional stiffness and mode of the hinge reinforcement plate 300 can be effectively improved.

[0048] It can be understood that the number of the first reinforcing rib 302 and the second reinforcing rib 303 can be flexibly set according to needs, and the directions of the two can be flexibly set according to factors such as the shape of the hinge reinforcement plate 300 and the distribution area of the hinge reinforcement plate 300 in the installation space.

[0049] Considering that the hinge of the rear door is provided at the top position, and in the application of adjusting the opening and closing of the rear door using the hinge, the force applied to the hinge area is relatively large. Therefore, in some embodiments of the present invention, the hinge reinforcement plate 300 extends downward from a position close to the hinge to a position close to the extension portion 301 and is provided with at least one reinforcing rib. The reinforcing rib arranged from top to bottom in this embodiment can effectively improve the strength of the top area of the rear door during the operation of the hinge. Moreover, when installing the high-mounted brake light on the extension portion 301, during the installation and after the assembly is completed, the extension portion 301 will be subjected to a force perpendicular to its own plate surface direction. Therefore, the hinge reinforcement plate 300 will be subjected to the torsion force brought by the extension portion 301. The arrangement of the reinforcing rib in this embodiment can also effectively overcome the torsion force in this direction, which is beneficial to improving the structural strength of the extension portion 301 and further ensuring the installation stability of the high-mounted brake light.

[0050] In some embodiments of the present invention, the extension portion 301 is located in the two side areas at the upper end of the installation window to support and fix the two ends of the high-mounted brake light.

[0051] Specifically, referring to Figures 2 to 5 , the rear door of this embodiment is provided with two hinge reinforcement plates 300, and the two hinge reinforcement plates 300 are respectively arranged in the two side areas at the upper end of the installation window. Each hinge reinforcement plate 300 extends an extension portion 301 at a vertex position of the installation window, so as to install the high-mounted brake light through the two extension portions 301. The arrangement form of the extension portion 301 in this embodiment is located at the two vertex positions of the installation window, which is convenient for designing a through-type high-mounted brake light. Referring to Figure 5 , an assembly gap is reserved between the outer plate 200 and the inner plate 100 corresponding to the two vertex positions at the upper end of the installation window, and this assembly gap satisfies that the extension portion 301 passes out from the installation space into the installation window. And this assembly gap is larger than the thickness of the penetrating part of the hinge reinforcement plate 300, so as to avoid interference and internal stress generation between them after the three are assembled and fixed. For the convenience of installing the high-mounted brake light, an 8*16mm guide hole is provided on the extension portion 301 to facilitate the quick positioning of the high-mounted brake light, and at the same time, an installation hole is provided for connection and fixation.

[0052] It can be understood that it is also possible to extend one hinge reinforcement plate 300 from the installation space to the two vertex positions of the installation window and then extend out to form two extension portions 301. It is also possible to only provide one extension portion 301 in the middle area at the top of the installation window, or provide more extension portions 301, or make the extension portion 301 extend from one side to the other side of the top of the installation window.

[0053] Referring to Figures 2 to 5, in some embodiments of the present utility model, both hinge reinforcement plates 300 extend from the upper region of the installation window to the side region of the installation window (one hinge reinforcement plate 300 is hidden in the figure). In this way, the upper and side regions of the installation window can be structurally strengthened by the hinge reinforcement plates 300, improving the structural strength of the rear door, thereby ensuring the support strength for the rear windshield, and also improving the force-bearing strength under the action of the hinge.

[0054] Based on the structure of the above embodiments, referring to Figure 7 , the hinge reinforcement plate 300 is provided with a first reinforcing rib 302 and a second reinforcing rib 303. The first reinforcing rib 302 extends downward from the upper end of the hinge reinforcement plate 300 to a position close to the extension portion 301, and the second reinforcing rib 303 extends upward from the bottom end of the hinge reinforcement plate 300 to intersect with the first reinforcing rib 302 and extends to the facing ends of the two hinge reinforcement plates 300. In this embodiment, the first reinforcing rib 302 and the second reinforcing rib 303 can radiate the entire plate surface of the hinge reinforcement plate 300, ensuring the structural strength of the hinge reinforcement plate 300 while controlling the number of reinforcing ribs.

[0055] Referring to Figure 1 , in some embodiments of the present utility model, the rear door further includes a strut reinforcement plate 500, and the strut reinforcement plate 500 is disposed in the installation space and connected to the taillight mounting plate 400. It can be understood that generally, the material grade and strength grade of the reinforcement plate are relatively high. In order to control the production cost, the material grade and strength grade of the inner panel 100, the outer panel 200, and the taillight mounting plate 400 are appropriately controlled. Since the taillight mounting plate 400 is connected between the edges of the inner panel 100 and the outer panel 200, its structural strength is limited. In this embodiment, the strut reinforcement plate 500 is used to connect the taillight mounting plate 400, which can effectively improve the structural strength of the taillight mounting plate 400 and avoid the problem of increased cost caused by overall increasing the material grade and strength grade of the inner panel 100, the outer panel 200, and the taillight mounting plate 400.

[0056] Referring to Figure 2 and Figure 4 , in some embodiments of the present utility model, the rear door is provided with two strut reinforcement plates 500, and the two strut reinforcement plates 500 are located on the left and right sides of the taillight mounting plate 400. Each strut reinforcement plate 500 extends out of the installation space from the edge of the first window 101 and is connected to the left end or the right end of the taillight mounting plate 400. Since the taillight mounting plate 400 is connected to the edge of the inner panel 100, with the structural arrangement of this embodiment, extending the strut reinforcement plate 500 out of the installation space to connect the taillight mounting plate 400 can effectively ensure the structural reinforcement of the taillight mounting plate 400.

[0057] Furthermore, referring to Figure 6, the part of the strut reinforcing plate 500 extending out of the installation space is provided with a lapping edge 501 between the edge of the first window 101 and the edge of the tail lamp mounting plate 400. The lapping edge 501 is connected to the edge of the second window 201 and is used to cooperate with the inner plate 100, the tail lamp mounting plate 400 and the outer plate 200 to jointly define an installation window. It can be understood that the strut reinforcing plate 500 of this embodiment extends from the installation space to the outside of the inner plate 100. Therefore, the first window 101 is formed by enclosing the edge of the strut reinforcing plate 500 (i.e., the lapping edge 501) and the edge of the tail lamp mounting plate 400 to form an annular first lapping area, and then connecting the edge of the second window 201 to define the installation window. Furthermore, it can be understood that the strut reinforcing plate 500 also constitutes an extended side wall of the inner plate 100. Thus, the strut reinforcing plate 500 can be used to further reduce the stamping depth of the inner plate 100, improve the forming quality and structural strength of the inner plate 100. At the same time, the strut reinforcing plate 500 can be used to effectively improve the structural strength and support strength of the tail lamp mounting plate 400 and is beneficial to controlling the production cost.

[0058] In practical applications, the part with a larger depth can be divided onto the tail lamp mounting plate 400 and the strut reinforcing plate 500 to ensure the forming quality of the overall back door.

[0059] In some embodiments of the present utility model, the two strut reinforcing plates 500 extend upward on the side of the installation window to connect to the hinge reinforcing plate 300. Thus, the strut reinforcing plate 500 and the hinge reinforcing plate 300 can be used to improve the structural strength on both sides of the installation window and ensure the support strength for the rear windshield.

[0060] In some embodiments of the present utility model, the tail lamp mounting plate 400 is provided with a plurality of weight-reducing holes 401 for realizing a lightweight design.

[0061] To better understand the back door in the present utility model, this embodiment proposes a back door. Refer to Figures 1 to 7, including an inner panel 100, an outer panel 200, two hinge reinforcement plates 300, two strut reinforcement plates 500, and a taillight mounting plate 400. Among them, the outer peripheral sides of the inner panel 100 and the outer panel 200 are welded and fixed to each other, and there is a sandwich space between the two, and an installation space is formed through this sandwich space. A first window 101 is opened on the inner panel 100, and a second window 201 is opened on the outer panel 200. The taillight mounting plate 400 is welded to the lower edge position of the first window 101. An installation structure matching the taillight is formed on the taillight mounting plate 400, and at the same time, a weight reduction hole 401 is also provided on the taillight mounting plate 400. The two strut reinforcement plates 500 are located on the left and right sides of the taillight mounting plate 400. Part of the plate surface of the strut reinforcement plate 500 is located in the installation space to structurally strengthen the area where the strut of the rear door is installed. Part of the plate surface of the strut reinforcement plate 500 extends from the edge of the first window 101 and extends along the side edge of the taillight mounting plate 400 to the end edge position of the taillight mounting plate 400. And the extended part of the plate surface extends to the side edge of the first window 101 at the end away from the taillight mounting plate 400, so as to form a lapping edge 501 between the end edge of the taillight mounting plate 400 and the side edge of the first window 101. The upper edge, two side edges of the first window 101, the lapping edge 501 of the strut reinforcement plate 500 and the end edge of the taillight mounting plate 400 together form a first lapping area. The material grade and strength grade of the hinge reinforcement plate 300 are higher than those of the taillight mounting plate 400. The edge of the second window 201 on the outer panel 200 matches the first lapping area and is welded and fixed to the first lapping area, so as to define an installation window for the rear windshield on the rear door. The two hinge reinforcement plates 300 are both arranged in the installation space and are located in the two side areas at the upper end of the installation window. Each hinge reinforcement plate 300 extends from the upper area of the installation window to the side area of the installation window. The hinge reinforcement plate 300 penetrates an extension part 301 between the inner panel 100 and the outer panel 200 at the top corner position of the installation window, and an installation structure matching the high-mounted brake light is provided on the extension part 301.

[0062] Adopting the structural arrangement of this embodiment has the following advantages:

[0063] 1. Using the strut reinforcement plate 500 and the taillight mounting plate 400 as the extended side walls of the inner panel 100 to connect with the outer panel 200 is beneficial to reducing the stamping depth of the inner panel 100, improving the forming quality and structural strength of the inner panel 100; and the taillight mounting plate 400 is formed separately, which can design a complex-shaped surface and can arrange mounting holes in different directions to meet different mounting requirements;

[0064] 2. The strut reinforcement plate 500 extends from the inner side of the inner panel 100 (i.e., the side of the inner panel 100 facing the outer panel 200) to connect the taillight mounting plate 400 and the outer panel 200, which can improve the support strength of the taillight mounting plate 400 and the outer panel 200, and is also conducive to controlling the production cost.

[0065] 3. The hinge reinforcement plate 300 extends from the upper end of the installation window to provide a mounting position for the high-mounted brake light, which can realize the built-in installation of the high-mounted brake light, optimize the design of the rear wing, and is conducive to the design of the fastback styling.

[0066] 4. The hinge reinforcement plate 300 is connected to the strut reinforcement plate 500 and is distributed on the periphery of the installation window, which can effectively improve the support strength of the rear windshield and the overall structural strength of the rear door.

[0067] 5. Based on the above settings, the rear door solves the problems of large stamping depth and difficult forming existing in the fastback styling design, and also solves the installation problems of the high-mounted brake light and the taillight.
