The back door decoration part is installed on the back door, and is mainly used for decorating the back door and protecting the internal structure of the back door. At present, the appearance and function of the back door decoration part are relatively single, and the installation reliability is insufficient. During the opening or closing of the back door, the back door decoration part is easily turned over, loosened or deformed under stress, and the service life is affected.

[0046] Therefore, the present embodiment provides a back door decoration structure of a vehicle.

[0047] A back door decoration structure of a vehicle includes a back door assembly 2 and a back door decoration part assembly 1 arranged at the lower part of the back door assembly 2. The back door assembly 2 includes a back door outer plate 201, and the back door decoration part assembly 1 includes a back door decoration part body 101 and a back door decoration part skeleton 102 connected with each other. The back door decoration part body 101 is arranged at the side of the back door outer plate 201 facing outward, the back door decoration part skeleton 102 is arranged at the side of the back door decoration part body 101 facing the back door outer plate 201, and a plurality of functional components are integrated in the back door decoration part skeleton 102. The back door decoration part skeleton 102 is connected with the back door outer plate 201, and an anti-turning-over structure is arranged between the back door decoration part skeleton 102 and the back door outer plate 201.

[0048] Referring to Figure 1 and Figure 2The back door decoration assembly 1 is installed at the lower part of the back door assembly 2 and is connected with the back door outer plate 201 in a gap fit between the upper and lower edges. The back door decoration assembly 1 adopts a double-layer structure and specifically includes a back door decoration body 101 and a back door decoration skeleton 102 which are connected and fixed with each other. The back door decoration body 101 is located at the outer side, that is, is installed at the side of the back door outer plate 201 facing outward, and mainly plays a role of decorating the back door. The back door decoration skeleton 102 is located at the inner side, that is, is installed at the side of the back door decoration body 101 facing the back door outer plate 201, and serves as a main installation and positioning structure for being installed and fixed with the back door outer plate 201 and functional components. Compared with the single-layer plate structure of the conventional back door decoration, the back door decoration assembly 1 in the embodiment adopts the double-layer structure, reduces the difficulty of complex modeling processing, can meet the diversified and personalized design requirements of modeling, and meanwhile, the double-layer structure improves the structural strength of the back door decoration assembly as a whole and the stress is not easy to be deformed in the process of opening and closing the back door. The back door decoration skeleton 102 is integrally provided with a plurality of functional components, which can be a buzzer, a touch switch, a camera, a license plate lamp and the like, and realizes the high integration of a plurality of electrical appliances and intelligent components and can meet the multi-functional requirements. The back door decoration skeleton 102 and the back door outer plate 201 are provided with an anti-turnover structure, which can avoid the back door decoration assembly 1 from being pressed inward and turned over when the user closes the back door, and ensure the installation stability and reliability of the back door decoration assembly 1.

[0049] Optionally, the anti-turnover structure includes a support piece 102-6 which is arranged at the side of the back door decoration skeleton 102 facing the back door outer plate 201, one end of the support piece 102-6 is fixedly connected with the back door decoration skeleton 102, and the other end of the support piece 102-6 is abutted against the back door outer plate 201.

[0050] Specifically, referring to Figure 7 and Figure 9 , the anti-turnover structure includes the support piece 102-6 which is arranged between the back door decoration skeleton 102 and the back door outer plate 201, one end of the support piece 102-6 is fixedly connected with the back door decoration skeleton 102, and the other end of the support piece 102-6 is abutted against the back door outer plate 201, which can limit the movement of the back door decoration skeleton 102 toward the side of the back door outer plate 201 and prevent the back door decoration assembly 1 from being turned inward when the back door is closed.
