Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vehicle body components, and in particular to a tailgate outer panel; at the same time, this utility model also relates to a tailgate and a vehicle having the tailgate outer panel. Background Technology
[0002] As a crucial automotive component, the tailgate outer panel is available in two types: one-piece and two-piece. Both types are primarily formed using cold stamping. The choice between one-piece and two-piece designs depends on product characteristics and overall production costs. Generally, if the angle between the upper part of the taillight and the stamping angle is obtuse, without negative angles, and the transition is smooth, a one-piece tailgate outer panel can be used. Besides one-piece tailgate outer panels, two-piece tailgate outer panels are also widely used in the industry.
[0003] However, the traditional split tailgate outer panel has an unreasonable structure, resulting in poor styling and refinement. In addition, the taillights are also installed on the tailgate outer panel, and the installation and matching effect between the taillights and the tailgate outer panel is unreasonable, which further highlights the problem of poor refinement of the tailgate outer panel. Utility Model Content
[0004] In view of this, the present invention aims to propose a rear door outer panel to enhance its sense of refinement.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A tailgate outer panel includes an upper outer panel and a lower outer panel connected together; the bottom of the upper outer panel has a lower edge portion located below the rear windshield mounting opening, and a bent portion connected to the lower edge portion, wherein the bent portion and the lower edge portion form an included angle α, and the included angle α is an acute angle.
[0007] The top of the lower outer panel has an extension portion extending toward the interior of the vehicle. The extension portion and the bent portion together form a taillight mounting groove, which is provided through the width of the outer rear door panel.
[0008] Furthermore, the bent portion forms the top and side walls of the mounting groove, and the extended portion forms the bottom wall of the taillight mounting groove.
[0009] Furthermore, the edge of the extended portion is provided with a flange, which is folded upward along the vertical direction of the vehicle, and the flange is connected to the bent portion.
[0010] Furthermore, the edge of the flange has an upwardly protruding portion, and the protruding portion is a plurality of portions spaced apart along the length direction of the flange.
[0011] Furthermore, the height H of the bent portion in the vertical direction of the vehicle is between 53mm and 57mm; and / or, the distance L between the flange and the extended portion in the vertical direction of the vehicle is between 23mm and 27mm.
[0012] Furthermore, the outer upper plate and the outer lower plate are welded together, and a welding positioning part is provided between the outer upper plate and the outer lower plate; the welding positioning part is used to position the relative position between the outer upper plate and the outer lower plate during welding.
[0013] Furthermore, the welding positioning part includes positioning holes respectively provided on the upper plate of the outer plate and the lower plate of the outer plate, and the positioning holes on the upper plate of the outer plate and the lower plate of the outer plate can be aligned so that the positioning fixture can pass through.
[0014] Furthermore, the outer plate upper and / or the outer plate lower plate are cold-stamped; and / or, the included angle α is between 50° and 55°.
[0015] Compared with the prior art, this utility model has the following advantages:
[0016] The tailgate outer panel of this utility model forms an angle α between the bent portion and the lower edge portion, and the angle α is an acute angle, which can provide more variation and a sense of layering for the rear shape of the vehicle, making the vehicle's appearance more unique and dynamic, and improving the refinement of the tailgate outer panel. Furthermore, the extended portion and the bent portion together form a through-type taillight mounting groove, which is conducive to the arrangement of through-type taillights and further enhances the refinement of the tailgate outer panel.
[0017] Furthermore, the top and side walls of the mounting slot are formed by the bent portion, and the bottom wall of the taillight mounting slot is formed by the extended portion. This makes the structure of the tailgate outer panel more compact and reasonable, facilitating the arrangement of the taillights and improving the overall strength and aesthetics of the tailgate outer panel. The extended portion is connected to the bent portion by a flange, facilitating the connection between the upper and lower outer panels. The flange also increases the strength of the extended portion, making the lower outer panel more stable under external pressure and impact. The multiple protrusions on the flange increase the connection area between the flange and the bent portion, thereby improving the connection strength between the upper and lower outer panels. The height H of the bent portion in the vertical direction of the vehicle ensures the specifications of the taillight mounting slot and the connection strength between the bent portion and the flange. The distance L between the flange and the extended portion in the vertical direction of the vehicle ensures sufficient support and fixing space for the taillights within the taillight mounting slot, and also ensures the connection strength between the bent portion and the flange.
[0018] Furthermore, the outer upper panel and the lower outer panel are welded together, which helps ensure the strength of the tailgate outer panel. The welding positioning part allows for faster and more accurate welding operations, reducing adjustment and alignment time and thus improving production efficiency. The positioning holes in the welding positioning part have a simple structure, are easy to manufacture, and provide good positioning. The outer upper and lower outer panels are cold-stamped, which facilitates processing and reduces production costs. The included angle α, between 50° and 55°, not only enhances the shape and refinement of the tailgate outer panel but also facilitates the formation of a stable taillight mounting slot structure.
[0019] In addition, another objective of this utility model is to provide a tailgate having the tailgate outer panel as described above.
[0020] The rear door of this utility model, by setting the rear door outer panel as described above, helps to improve the exquisite appearance.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] Example 1
[0039] This embodiment relates to a tailgate outer panel that optimizes its structure to facilitate taillight arrangement and also addresses the problem of poor refinement in existing tailgate outer panels.
[0040] In terms of overall structure, this embodiment includes a connected outer upper panel 1 and an outer lower panel 2. The bottom of the outer upper panel 1 has a lower edge portion 101 located below the rear windshield mounting opening 103, and a bent portion 102 connected to the lower edge portion 101. An angle α is formed between the bent portion 102 and the lower edge portion 101, and the angle α is an acute angle. The top of the outer lower panel 2 has an extension portion 201 extending towards the interior of the vehicle. The extension portion 201 and the bent portion 102 form a taillight mounting groove 100, and the taillight mounting groove 100 is provided through the width direction of the tailgate outer panel.
[0041] The tailgate outer panel described in this embodiment forms an angle α between the bent portion 102 and the lower edge portion 101, and the angle α is an acute angle, which can provide more variation and layering for the styling of the rear of the vehicle, making the appearance of the vehicle more unique and dynamic, and improving the refinement of the tailgate outer panel. Furthermore, the extended portion 201 and the bent portion 102 together form a through-type taillight mounting groove 100, which is conducive to the arrangement of through-type taillights and further enhances the refinement of the tailgate outer panel.
[0042] Based on the above overview, an exemplary structure of the rear door outer panel described in this embodiment is as follows: Figures 1 to 4 As shown. And, still combined Figure 1 As shown, the taillight mounting groove 100 is provided through the width direction of the outer panel of the rear tailgate, that is, the taillight mounting groove 100 extends from one side of the outer panel of the rear tailgate width direction to the other side of the outer panel of the rear tailgate width direction.
[0043] In this embodiment, the lower edge portion 101 is inclined downward along the extension direction of the outer upper plate 1, and the bent portion 102 is bent from the bottom of the outer upper plate 1 toward the inner panel of the tailgate, and the bent portion 102 extends along the width direction of the outer panel of the tailgate. The lower edge portion 101 is folded inward relative to the lower outer plate 2 and extends along the width direction of the outer panel of the tailgate. This facilitates the formation of a through-type taillight mounting groove 100 between the bent portion 102 and the extended portion 201, thereby facilitating the installation of a through-type taillight.
[0044] As a preferred implementation method, such as Figure 4 As shown, the bent portion 102 forms the top wall 104 and side wall 105 of the mounting groove, and the extended portion 201 forms the bottom wall 106 of the taillight mounting groove 100. This arrangement makes the structure of the tailgate outer panel more compact and reasonable, facilitates the arrangement of taillights, and also helps to improve the overall strength and aesthetics of the tailgate outer panel.
[0045] Specifically, such as Figure 5As shown, the bent portion 102 in this embodiment has a first segment 1021 connected to the lower edge portion 101 and extending along the longitudinal direction of the vehicle, and a second segment 1022 connected to the first segment 1021 and extending downward along the vertical direction of the vehicle. The first segment 1021 forms the top wall 104 of the taillight mounting groove 100, and the second segment 1022 forms the side wall 105 of the taillight mounting groove 100. The first segment 1021 and the lower edge portion 101 form the aforementioned included angle α, and the second segment 1022 is connected to the extended portion 201.
[0046] To facilitate the connection between the extension portion 201 and the bending portion 102, such as Figure 4 and Figure 6 As shown, the edge of the extension portion 201 is provided with a flange 202, which folds upward along the vertical direction of the vehicle and connects to the bent portion 102. Here, the extension portion 201 is connected to the bent portion 102 through the flange 202, which facilitates the connection between the outer upper plate 1 and the outer lower plate 2. At the same time, the flange 202 also helps to increase the strength of the extension portion 201, making the outer lower plate 2 more stable when subjected to external pressure and impact.
[0047] In terms of specific structure, such as Figure 4 As shown, the flange 202 and the extension 201 are stacked together in the front-rear direction of the vehicle, which increases the contact area between the two, thereby improving the connection strength between the flange 202 and the extension 201, as well as the stability of the taillight mounting slot 100. In a preferred embodiment, the edge of the flange 202 has an upwardly protruding portion 2021, and multiple protruding portions 2021 are spaced apart along the length of the flange 202. By providing multiple protruding portions 2021, the connection area between the flange 202 and the bent portion 102 is increased, thereby improving the connection strength between the outer upper plate 1 and the outer lower plate 2.
[0048] As a preferred connection method, the outer upper plate 1 and the outer lower plate 2 are welded together, and a welding positioning part is provided between the outer upper plate 1 and the outer lower plate 2. The welding positioning part is used to position the relative position between the outer upper plate 1 and the outer lower plate 2 during welding. Here, the outer upper plate 1 and the outer lower plate 2 are welded together, which helps to ensure the strength of the rear door outer panel. By setting up the welding positioning part, the welding operation can be faster and more accurate, reducing the adjustment and alignment time, thereby improving production efficiency.
[0049] In practice, the protruding portion 2021 on the flange 202 is connected to the second segment 1022 of the bent portion 102 by spot welding. Compared with other welding methods, spot welding is very fast, which helps to improve production efficiency. In addition, spot welding can provide more stable welding quality, thereby ensuring the connection strength between the flange 202 and the bent portion 102, as well as the structural stability of the taillight mounting groove 100. At the same time, during the spot welding process, the protruding portion on the flange 202 and the second segment 1022 of the bent portion 102 will not deform, thus eliminating the problem of non-compliance with precision caused by welding deformation.
[0050] As one feasible implementation, the welding positioning part includes positioning holes respectively provided on the outer plate 1 and the outer plate 2, and the positioning holes on the outer plate 1 and the outer plate 2 can be aligned to allow the positioning fixture to pass through. Here, the positioning hole has a simple structure, is easy to process and manufacture, and has a good positioning effect. For ease of description, the positioning hole provided on the outer plate 1 is referred to as the first positioning hole 1025, and the positioning hole provided on the outer plate 2 is referred to as the second positioning hole 2022.
[0051] like Figure 5 and Figure 6 As shown, the first positioning holes 1025 are respectively disposed at both ends of the second segment 1022 of the bent portion 102, and the second positioning holes 2022 are disposed in a one-to-one correspondence with the first positioning holes 1025 at each of the protruding portions 2021 at both ends of the flange 202. By aligning the first positioning holes 1025 and the corresponding second positioning holes 2022, the alignment of the outer plate 1 and the outer plate 2 can be achieved, thereby improving the welding efficiency between the protruding portions 2021 and the second segment 1022.
[0052] As a preferred implementation method, such as Figure 4 As shown, the height H of the bent portion 102 in the vertical direction of the vehicle is between 53mm and 57mm. This not only ensures the specifications of the taillight mounting slot 100 but also ensures the connection strength between the bent portion 102 and the flange 202. Here, the height H specifically refers to the height of the second segment 1022. In practice, the height H can be, for example, 53mm, 54mm, 55mm, 56mm, or 57mm. When the height H is less than 53mm, the contact area between the second segment 1022 and the flange 202 is small, which is detrimental to ensuring the connection strength between the bent portion 102 and the flange 202. When the height H is greater than 57mm, the height of the taillight mounting slot 100 becomes larger, requiring the installation of a wider taillight, which is detrimental to improving the taillight's aesthetic appeal.
[0053] In addition, still refer to Figure 4As shown, the distance L between the flange 202 and the extension 201 in the vertical direction of the vehicle is between 23mm and 27mm. This arrangement helps ensure that the taillight has sufficient support and fixing space within the taillight mounting slot 100, and also helps ensure the connection strength between the bent portion 102 and the flange 202. In specific implementations, the distance L can be, for example, 23mm, 24mm, 25mm, 26mm, or 27mm. When the distance L is less than 23mm, the contact area between the second segment 1022 and the flange 202 is small, which is not conducive to ensuring the connection strength between the bent portion 102 and the flange 202. When the height H is greater than 27mm, the height of the taillight mounting slot 100 becomes larger, and a wider taillight needs to be installed, which is not conducive to improving the refinement of the taillight.
[0054] When the height H of the bent portion 102 in the vertical direction of the vehicle is between 53mm and 57mm, and the distance L between the flange 202 and the extension portion 201 in the vertical direction of the vehicle is between 23mm and 27mm, both conditions are met simultaneously. This not only helps to further improve the connection strength between the flange 202 and the bent portion 102, but also makes the height of the taillight mounting slot 100 more reasonable, which is conducive to the exquisite shape of the taillight, thus making the appearance of the vehicle more unique and dynamic.
[0055] To facilitate the installation of the taillights in the taillight mounting slot 100, such as Figure 5 As shown, the second section 1022 of the bent portion 102 is provided with connecting holes 1023 spaced apart along its own length. The structure of the connecting holes 1023 is easy to process and shape, which is beneficial for the installation of taillights. To further improve the structural strength of the taillight connection, multiple protrusions 1024 spaced apart along the width direction of the rear tailgate outer panel can be provided on the second section 1022, and the connecting holes 1023 are respectively provided on the protrusions 1024.
[0056] In specific implementation, a portion of the protrusions 1024 protrudes backward along the front-rear direction of the vehicle, while another portion of the protrusions 1024 protrudes forward along the front-rear direction of the vehicle. The flange 202 is set in accordance with the shape of each protrusion 1024. The fact that each protrusion 1024 and the flange 202 are set in accordance with the shape of the protrusions 1024 helps to improve the structural strength at the connecting hole 1023. Moreover, the structure of the protrusions 1024 is simple and easy to process and form.
[0057] In this embodiment, as Figure 4As shown, the included angle α is between 50° and 55°. This range of angle α not only improves the shape and refinement of the tailgate outer panel but also facilitates the formation of a stable taillight mounting slot 100 structure. In practice, the included angle α can be, for example, 50°, 51°, 52°, 53°, 54°, or 55°. When the included angle α is less than 50°, there are difficulties in processing and forming; while when the included angle α is greater than 55°, it is detrimental to the shaping effect of the tailgate outer panel.
[0058] To ensure the included angle α is between 50° and 55°, and to prevent cracking and failure to form the bent portion 102 due to direct drawing, the initial angle α needs to be set relatively large during the forming process. For example, the initial angle α can be set to 70° (this angle can be adjusted according to the final forming angle of α). By adding a side-shaping process, the included angle α can be shaped to between 50° and 55°. During the side-shaping of the bent portion 102, considering the relatively large lateral force in the local area, the bent portion 102 can be rotated. The rotation angle is determined according to the usage requirements, as long as the included angle α is shaped to between 50° and 55° after shaping.
[0059] As a preferred forming method, both the outer upper plate 1 and the outer lower plate 2 in this embodiment are formed by cold stamping. Compared with the prior art solution of partially adding plastic parts, this method has a higher production cycle and lower production cost. Furthermore, during the stamping process, the metal sheet undergoes plastic deformation, which helps to improve the strength and hardness of the outer upper plate 1 and the outer lower plate 2. Of course, it is also feasible to use only one of the outer upper plate 1 and the outer lower plate 2 for cold stamping, while the other uses another forming method.
[0060] The tailgate outer panel described in this embodiment achieves a better styling and layering effect by optimizing the included angle α between the bent portion 102 and the lower edge portion 101 to an acute angle. The flange 202 with protruding portions 2021 on the first and second sections 1021 of the bent portion 102, and on the extended portion 201, facilitates the connection between the outer upper panel 1 and the outer lower panel 2. This tailgate outer panel not only enhances its own aesthetic refinement but also facilitates the arrangement of a continuous taillight, thereby improving the dynamics and layering of the vehicle's rear. Furthermore, both the outer upper panel 1 and the outer lower panel 2 are cold-stamped, which, while meeting the requirements of rapid production, also helps reduce overall vehicle production costs.
