[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] The following is for reference. Figures 1-4 The present application describes a tailgate assembly 10 for a vehicle, which includes a tailgate sheet metal part 11 and an exterior trim panel 12.

[0031] The tailgate sheet metal 11 is rotatably connected to the vehicle body. At least a portion of the exterior trim panel 12 is spaced apart from the tailgate sheet metal 11 to form a cavity 13. One end of the exterior trim panel 12 is connected to the tailgate sheet metal 11, and the other end of the exterior trim panel 12 forms an extension segment 123 extending toward the tailgate sheet metal 11. The free end of the extension segment 123 forms a first end face 1231, and a protrusion 124 extending toward and spaced apart from the tailgate sheet metal 11 is formed on the first end face 1231. The protrusion 124 is disposed adjacent to the cavity 13.

[0032] Currently, tailgate exterior panels are widely used in SUV models. Painted in the same color as the vehicle body, they are located in the center of the tailgate and primarily serve a decorative and aesthetic purpose, while also providing functionality for opening and closing the trunk and illuminating the license plate. They are used frequently. However, existing tailgates experience vibrations during opening and closing, causing the exterior panel to repeatedly impact the sheet metal and paint surface, resulting in paint damage and peeling, affecting the aesthetics.

[0033] In response, this application proposes a tailgate assembly 10 for a vehicle, which can prevent paint damage and peeling of the tailgate sheet metal 11, thereby improving the aesthetics of the tailgate sheet metal 11. Figure 1 As shown, specifically, the tailgate assembly 10 may include a tailgate sheet metal part 11 and an exterior trim panel 12. The tailgate sheet metal part 11 can be rotatably connected to the vehicle body. The tailgate sheet metal part 11 can be used to install parts such as a tailgate lock and a tailgate license plate. At least a portion of the exterior trim panel 12 can be spaced apart from the tailgate sheet metal part 11 to form a cavity 13. One end of the exterior trim panel 12 can be connected to the tailgate sheet metal part 11. Optionally, the exterior trim panel 12 and the tailgate sheet metal part 11 can be connected by a universal snap-fit ​​structure. The snap-fit ​​structure can be fixed to the tailgate sheet metal part 11. The exterior trim panel 12 can be connected between the snap-fit ​​structure and the tailgate window to fix one end of the exterior trim panel 12.

[0034] like Figure 2 and Figure 3As shown, the other end of the exterior panel 12 may have an extension section 123, which extends toward the tailgate sheet metal 11. The extension section 123 can prevent rainwater from entering the cavity 13 and affecting the internal electrical components. The free end of the extension section 123 may have a first end face 1231, on which a protrusion 124 extending toward the tailgate sheet metal 11 may be formed. The end of the protrusion 124 may be spaced apart from the tailgate sheet metal 11 to avoid the protrusion 124 directly abutting against the tailgate sheet metal 11 and causing it to deform.

[0035] Furthermore, such as Figure 4 As shown, the protrusion 124 can be disposed adjacent to the cavity 13. It is understood that when the user frequently closes the tailgate assembly 10, the protrusion 124 will come into contact with the tailgate sheet metal 11 under the influence of vibration. Since the protrusion 124 is disposed adjacent to the cavity 13, the exposed part of the tailgate sheet metal 11 is painted, while the part of the tailgate sheet metal 11 located inside the cavity 13 is not painted. Therefore, when the protrusion 124 comes into contact with the tailgate sheet metal 11, it will not come into contact with the painted part of the tailgate sheet metal 11, thereby avoiding damage and peeling of the paint film on the tailgate sheet metal 11 and improving the aesthetics of the tailgate sheet metal 11.

[0036] In short, the tailgate assembly 10 of this application embodiment has a tailgate sheet metal part 11 and an outer trim panel 12. One end of the outer trim panel 12 is connected to the tailgate sheet metal part 11, and the other end of the outer trim panel 12 forms an extension section 123. The extension section 123 extends toward the tailgate sheet metal part 11, and a protrusion 124 is formed at the end of the extension section 123. A cavity 13 is formed between a portion of the outer trim panel 12 and the tailgate sheet metal part 11. The protrusion 124 can be disposed adjacent to the cavity 13. Therefore, when the user frequently closes the tailgate assembly 10, the protrusion 124 will contact the unpainted part of the tailgate sheet metal part 11 under the influence of vibration, effectively preventing the paint film of the tailgate sheet metal part 11 from being damaged and peeling off, and improving the aesthetics of the tailgate sheet metal part 11.

[0037] like Figure 2As shown, in some embodiments of this application, the tailgate sheet metal 11 may include an inner panel 111 and an outer panel 112. The inner panel 111 may be rotatably connected to the vehicle body. Optionally, the inner panel 111 and the vehicle body may be linked by a pivot. The outer panel 112 may be disposed on the inner panel 111, and at least a portion of the outer panel 112 may be spaced apart from the inner panel 111. Further, one end of the outer trim panel 12 may be connected to the side of the outer panel 112 away from the inner panel 111. Optionally, the outer trim panel 12 and the outer panel 112 may be interchangeable. A snap-fit ​​structure enables connection and can be fixed to the outer panel 112. The outer trim panel 12 can be connected between the snap-fit ​​structure and the tailgate window to fix one end of the outer trim panel 12. The protrusion 124 can be spaced apart from the outer panel 112. The side of the outer panel 112 away from the inner panel 111 has a painted part and an unpainted part. When the user frequently closes the tailgate assembly 10, the protrusion 124 will contact the unpainted part on the outer panel 112 under the influence of vibration, effectively avoiding the problem of paint film damage and peeling of the tailgate sheet metal 11.

[0038] like Figure 3 As shown, in some embodiments of this application, the outer panel 12 may further include a first panel 121 and a second panel 122. One end of the first panel 121 can be connected to the outer panel 112, and one end of the second panel 122 can be connected to the other end of the first panel 121. The other end of the second panel 122 extends toward the outer panel 112, and an extension segment 123 is formed at the other end of the second panel 122. A protrusion 124 is formed at the end of the extension segment 123 toward the outer panel 112. The end of the protrusion 124 toward the outer panel 112 is defined as a second end face 1241. The second end face 1241 is at least partially parallel to the outer panel 112. This arrangement can increase the contact area between the protrusion 124 and the outer panel 112, thereby avoiding deformation of the outer panel 112 after collision with the protrusion 124 and improving the aesthetics of the outer panel 112.

[0039] like Figure 3 As shown, in some embodiments of this application, the rear door assembly 10 may further include a buffer 14. At least a portion of the buffer 14 may be located between the protrusion 124 and the outer panel 112, and at least a portion of the buffer 14 may cover the second end face 1241. The buffer 14 can be connected to the second end face 1241. Optionally, the buffer 14 and the second end face 1241 may be bonded and fixed by the contact surface. The buffer 14 can absorb the collision force between the protrusion 124 and the outer panel 112, reduce the deformation of the outer panel 112, and ensure the aesthetics of the outer panel 112. In some embodiments, the buffer 14 may be constructed as a sponge strip.

[0040] Furthermore, such as Figure 4As shown, the buffer 14 may include a first segment 141 and a second segment 142. The first segment 141 may extend along a first direction, and one end of the first segment along a second direction may be connected to the extension segment 123. The second segment 142 may be connected to the end of the first segment 141 facing the outer plate 112, and the second segment 142 may extend in the second direction. The second segment 142 may cover the second end face 1241, and the second segment 142 may be connected to the second end face 1241. The first direction and the second direction are orthogonal. It should be noted that the first segment 141 may be connected to the extension segment 123. Optionally, the first segment 141 and the extension segment 123 may be directly bonded and fixed through the contact surface, which increases the contact area and makes the connection of the buffer 14 more secure.

[0041] like Figure 4 As shown, in some embodiments of this application, the distance between the second end face 1241 and the first end face 1231 along the first direction is L1, satisfying the relationship: 0.5mm≤L1≤1mm. It can be understood that the distance between the second end face 1241 and the first end face 1231 along the first direction can be any value between 0.5mm and 1mm. For example, the distance between the second end face 1241 and the first end face 1231 along the first direction can be, but is not limited to, 0.5mm, 0.7mm, 0.9mm, 1mm, etc. This arrangement allows the protrusion 124 to effectively contact the outer panel 112, avoiding the problem of paint film damage and peeling off of the back door sheet metal 11.

[0042] like Figure 4 As shown, in some embodiments of this application, the size of the protrusion 124 in the second direction is L2, satisfying the relationship: 1.8mm≤L2≤2.2mm. It can be understood that the size of the protrusion 124 in the second direction can be any value between 1.8mm and 2.2mm. For example, the size of the protrusion 124 in the second direction can be, but is not limited to, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, etc. This setting can make the contact area between the protrusion 124 and the outer plate 112 reasonable, avoid deformation after the outer plate 112 collides with the protrusion 124, and improve the aesthetics of the outer plate 112.

[0043] like Figure 4As shown, in some embodiments of this application, the minimum distance between the second end face 1241 and the outer plate 112 along the first direction is L3, satisfying the relationship: 0.2mm≤L3≤0.8mm. It can be understood that the minimum distance between the second end face 1241 and the outer plate 112 along the first direction can be any value between 0.2mm and 0.8mm. For example, the minimum distance between the second end face 1241 and the outer plate 112 along the first direction can be, but is not limited to, 0.2mm, 0.4mm, 0.6mm, 0.8mm, etc. This setting can reduce the gap between the protrusion 124 and the outer plate 112, prevent rainwater from entering the cavity 13 and affecting the internal electrical components, and improve the overall aesthetics.

[0044] The vehicle of the embodiment of this application is briefly described below.

[0045] The vehicle according to the present application embodiment is provided with the tailgate assembly 10 of the above embodiment.

[0046] Therefore, the tailgate assembly 10 of the vehicle has a tailgate sheet metal part 11 and an exterior trim panel 12. One end of the exterior trim panel 12 is connected to the tailgate sheet metal part 11, and the other end of the exterior trim panel 12 forms an extension section 123. The extension section 123 extends toward the tailgate sheet metal part 11, and a protrusion 124 is formed at the end of the extension section 123. A cavity 13 is formed between a portion of the exterior trim panel 12 and the tailgate sheet metal part 11. The protrusion 124 can be arranged adjacent to the cavity 13. Therefore, when the user frequently closes the tailgate assembly 10, the protrusion 124 will contact the unpainted part of the tailgate sheet metal part 11 under the influence of vibration, effectively preventing the paint film of the tailgate sheet metal part 11 from being damaged and peeling off, and improving the aesthetics of the vehicle.
