[0002] With the development of technology and the improvement of living standards, people have put forward higher and higher requirements for vehicle performance and appearance. Among them, the tailgate assembly structure, which allows the tailgate to open and close relative to the vehicle body, plays a relatively important role.

[0003] In existing technologies, an opening is typically provided at the rear end of the vehicle's side panel as a tailgate seam, allowing the tailgate to close at the seam. However, traditional processes make it difficult to place the tailgate seam on the side panel, resulting in a larger tailgate size to meet styling requirements. Furthermore, mismatches at the seams of tailgate components can easily occur, affecting the vehicle's appearance (DTS). It also makes the internal structure of the tailgate and side panel easily visible, impacting the overall aesthetics. Summary of the Invention

[0034] Reference Figures 1 to 4The diagram shows a schematic of a tailgate assembly structure according to an embodiment of this application. The tailgate assembly structure may specifically include: a side panel 10, a water channel trim panel 20, and a tailgate trim panel 30; the side panel 10 has a tailgate seam 11 on its side, and the water channel trim panel 20 is connected to the side panel 10 along the width direction of the vehicle; the tailgate trim panel 30 is movably connected to the side panel 10 near the tailgate seam 11, and there is a gap between the tailgate trim panel 30 and the tailgate seam 11; at least one of the water channel trim panel 20 and the tailgate trim panel 30 is provided with a shielding structure to shield the interior of the tailgate assembly structure exposed at the gap.

[0035] In this embodiment, the tailgate seam 11 of the side panel 10 is located on the side, allowing the tailgate to have a larger dimension along the width direction of the vehicle, providing a wider opening and closing range and meeting the tailgate's styling requirements. The water channel trim panel 20 is connected to the side panel 10 along the width direction of the vehicle, and a gap is provided between the tailgate trim panel 30 and the tailgate seam 11, resulting in a better edge seam matching effect when the tailgate is closed on the side panel 10, thus achieving a better DTS (Design for Transformers) matching effect for the vehicle's appearance. Furthermore, at least one of the water channel trim panel 20 and the tailgate trim panel 30 is provided with a shielding structure to conceal the internal structure of the tailgate assembly, preventing the internal structure of the tailgate and side panel 10 from being easily seen, further improving the vehicle's appearance and enhancing the user experience.

[0036] Specifically, in this embodiment, the tailgate seam 11 refers to an opening on the side panel 10 serving as a seam line, used to close the tailgate at the opening, thus enabling the tailgate to have an opening and closing function. The tailgate seam 11 is provided on the side of the side panel 10, meaning that the tailgate seam 11 is visible in the side view of the vehicle (view towards the door), unlike related technologies where the tailgate seam line is usually provided at the rear end of the side panel 10, meaning that the tailgate seam line is visible in the rear view of the vehicle (view towards the tailgate), but not in the side view of the vehicle.

[0037] Traditional manufacturing processes for side panels 10 and tailgates make it difficult to ensure that the tailgate seam 11 on the side of the side panel 10 meets the vehicle's appearance DTS (Dimension Technical Specifications) matching requirements. This results in poor gap matching at the seams, making the internal structure of the tailgate and side panel 10 easily visible and affecting the vehicle's appearance. Furthermore, the compact internal structure of the tailgate assembly leads to insufficient clearance during opening and closing, causing wear and reducing the vehicle's lifespan. In this embodiment, the water channel trim panel 20 is connected to the side panel 10 along the width direction of the vehicle. A gap exists between the tailgate trim panel 30 and the tailgate seam 11. By providing a shielding structure in at least one of the water channel trim panel 20 and the tailgate trim panel 30, the internal structure of the tailgate assembly is shielded, preventing the internal structure of the tailgate and side panel 10 from being easily visible, thus achieving a better appearance DTS matching effect for the vehicle.

[0038] Optionally, in this embodiment, the shielding structure includes a first skirt 21, which is disposed on the water channel trim panel 20. The back door assembly structure includes a water channel plate 40, the end of which is connected to the side panel 10 to form a connecting portion 12. For example, the water channel trim panel 20 is connected to the side panel 10 and covers the water channel plate 40, with the first skirt 21 shielding the connecting portion 12. In this way, the first skirt 21 of the water channel trim panel 20 shields the connecting portion 12 between the water channel plate 40 and the side panel 10. For example, the connecting portion 12 can be a welding point where the end of the water channel plate 40 is welded to the side panel 10, which can easily be exposed through the gap between the back door trim panel 30 and the back door seam 11, affecting the appearance of the back door assembly structure. Therefore, by using the first skirt 21 to cover the connecting part 12, the connecting part 12 is prevented from being exposed and easily seen, thus covering the internal structure of the side panel 10 and improving the appearance of the outer structure of the side panel 10.

[0039] In some optional embodiments of this application, the back door assembly structure includes a snap-fit ​​structure, through which the water channel trim panel 20 is connected to the water channel plate 40. The structure is simple, easy to implement, widely applicable, and easy to operate. For example, the snap-fit ​​structure can be a buckle or a slot, etc., and the specific type of snap-fit ​​structure is not limited in the embodiments of this application.

[0040] Optionally, in this embodiment, the edge of the tailgate trim panel 30 is provided with a folded edge 31 that folds inward toward the vehicle interior, and the folded edge 31 is arranged parallel to the first skirt edge 21. In this way, interference between the edge of the tailgate trim panel 30 and the first skirt edge 21 of the water channel trim panel 20 is avoided, so that there is a sufficient gap between the tailgate trim panel 30 and the side panel 10, so as to achieve a smoother opening and closing of the tailgate.

[0041] For example, the structural arrangement of this application embodiment reduces the gap between the rear door trim panel 30 and the side panel 10 to 4mm. In related technologies, a larger gap, typically 5mm, is usually required between the rear door trim panel 30 and the side panel 10 to enable smooth opening and closing of the rear door. This application embodiment, however, reduces the gap between the rear door trim panel 30 and the side panel 10 without increasing it, thus providing the rear door with sufficient clearance for smooth opening and closing.

[0042] Optionally, in this embodiment, the shielding structure further includes a second skirt 32, which is disposed on the rear door trim panel 30. The rear door assembly structure includes a rear door panel 50, which is connected to the inner side of the rear door trim panel 30. The rear door panel 50 has a seam 51, and the second skirt 32 shields the seam 51. For example, the rear door panel 50 may include an outer rear door panel 52 and an inner rear door panel 53, with the seam 51 formed at the edge where the outer rear door panel 52 and the inner rear door panel 53 connect. By shielding the seam 51 of the rear door panel 50 with the second skirt 32 disposed on the rear door trim panel 30, the seam 51 of the rear door panel 50 is prevented from being exposed and easily seen, thus shielding the internal structure of the rear door panel 50 and improving the appearance of the rear door structure.

[0043] In the embodiments of this application, optionally, as shown... Figure 3 As shown, the shielding structure includes a sealing member 54. The tailgate panel 50 includes an inner tailgate panel 53. The sealing member 54 is disposed on the inner tailgate panel 53, which has an opening. The sealing member 54 seals the opening to shield it. For example, the inner tailgate panel 53 is at least partially spaced from the outer tailgate panel 52. During assembly, an installation tool needs to be passed through the opening in the inner tailgate panel 53 to install the fastener 33 onto the outer tailgate panel 52 and the tailgate trim panel 30. After the outer tailgate panel 52 and the tailgate trim panel 30 are fastened, the opening through which the installation tool passed will remain, potentially exposing the internal structure of the tailgate assembly. Therefore, the sealing member 54 shields the opening, preventing exposure of the internal structure of the tailgate assembly and resulting in a better appearance for the tailgate assembly.

[0044] In this embodiment, optionally, the tailgate panel 50 includes an outer tailgate panel 52, and the tailgate assembly structure includes a fastener 33. The fastener 33 is sequentially inserted through the outer tailgate panel 52 and the tailgate trim panel 30 to fix the outer tailgate panel 52 to the tailgate trim panel 30. An opening on the inner tailgate panel 53 is positioned opposite the fastener 33, thereby allowing the sealing member 54 covering the opening to effectively conceal the fastener 33 and the outer tailgate panel 52, which are easily exposed at the opening. Furthermore, the fastener 33 provides a more stable and reliable connection between the tailgate trim panel 30 and the outer tailgate panel 52, improving the structural strength of the tailgate trim panel 30 and the tailgate panel 50. For example, the fastener 33 can be a bolt, stud, screw, nut, or rivet, etc. This embodiment does not limit the specific type of the fastener 33.

[0045] Furthermore, the number of fasteners 33 can be one, two, three, five, eight, etc., and can be set according to actual needs. Multiple fasteners 33 can be evenly spaced, symmetrically distributed, or spaced according to force requirements, etc. The specific distribution method of fasteners 33 in this application embodiment is not limited.

[0046] Optionally, in this embodiment, the tailgate trim panel 30 includes an outer surface 34 and a mounting surface 35 that are disposed opposite to each other. The mounting surface 35 is connected to the tailgate panel 50, and the included angle between the outer surface 34 and the mounting surface 35 is less than or equal to 20°. This allows for better adjustment of the gap and surface difference between the outer surface 34 of the tailgate trim panel 30 and the side panel 10 structure during subsequent assembly, resulting in better fit between the tailgate trim panel 30 and the side panel 10 and better meeting the vehicle's appearance DTS matching requirements.

[0047] For example, in the embodiments of this application, the included angle between the outer surface 34 and the mounting surface 35 can be 18°, 15°, 10°, 8°, etc., and can be set according to actual needs and process requirements. The specific value of the included angle between the outer surface 34 and the mounting surface 35 in the embodiments of this application is not limited.

[0048] In this embodiment, optionally, the back door assembly structure includes adhesive members that are connected to the side panel 10 and the drainage channel plate 40, respectively, and the side panel 10 is welded to the drainage channel plate 40. For example, the adhesive members can be installed using an adhesive application process. This provides a more stable connection between the side panel 10 and the drainage channel plate 40, resulting in better welding reliability and stability, and improving the structural strength of the side panel 10.
