[0015] It should be noted that the first decorative component 1 and the second decorative component 2 are not limited to the appearance structures shown in the figure, but also include other various appearance structures designed according to styling requirements.

[0016] Specifically, in this embodiment, the above-mentioned snap-on tongue piece 3 is made of metal and is set to a circular arc fold structure. One end of the circular arc fold is fixed by the snap-on tongue piece 21, and the other end of the circular arc fold is inserted into the first slot 11 to achieve the bridge connection between the first decorative piece 1 and the second decorative piece 2. The flatness of the first decorative piece 1 and the second decorative piece 2 is ensured based on the fold structure of the snap-on tongue piece 3. In order to better illustrate the technical solution of this embodiment, the snap-on tongue piece 3 is further described, as shown in FIG. Figure 5As shown, the side view structure of the snap-in tongue 3 is an arc shape, and the middle position of the arc shape is set as a fold 31. In addition, the arc edge of the above-mentioned snap-in tongue 3 is a tongue cutting edge, and a cutout 32 for cooperating with the tongue buckle 21 to limit the position is provided on the tongue cutting edge of the snap-in tongue 3. The snap-in tongue 3 is snapped at the cutout 32 by the tongue buckle 21 for limit. The snap-in tongue 3 is limited at the cutout 32; the tongue cutting edge of the snap-in tongue 3 extends vertically outward to set a limiting piece 33, and the limiting piece 33 is close to the cutout 32 and is located on the side of the snap-in tongue 3 that cooperates with the first slot 11.

[0017] It should be noted that the tongue inner buckle 21 is any fixed buckle in the prior art that can be engaged with the cutout 32. In addition, the arrangement of the snap tongue 3 on the second decorative piece 2 is not limited to the above-mentioned one, and includes any other forms that can be engaged with the fixed buckle. In addition, in order to facilitate bridging, the two ends of the tongue cut edge of the snap tongue 3 are respectively provided with cut corners 34, and the cut corners 34 are convenient for insertion during the installation process of the first decorative piece 1 and the second decorative piece 2.

[0018] According to the above contents, during the assembly process, the tongue piece inner buckle 21 is used to bridge the snap-fit ​​tongue piece 3 and the second decorative piece 2 to form a combined body, such as Figure 6 As shown, usually, during the assembly process, the arched side of the latching tongue piece 3 corresponds to the outer sides of the first decorative piece 1 and the second decorative piece 2 .

[0019] In this embodiment, the first decorative part 1 is provided with three layers, which are respectively a metal shell 12 , an internal rubber 13 , and an internal metal 14 from the outside to the inside. The first slot 11 is formed by the cavity of the internal metal 14 , and its shape matches the shape of the snap-on tongue piece 3 .

[0020] During assembly, the first trim 1 is assembled with the above-mentioned combination (the snap-on tongue 3 is bridged with the second trim 2). In this process, the cut edge of the second trim 2 is the reference for the assembly of the first trim 1 in the F / A direction (or other directions, determined by the actual direction of the vehicle body where the docking structure is located, not limited to a certain direction). Usually, the first trim 1 and the second trim 2 are fitted in the F / A direction by manually pushing and tightening. Relying on the elasticity of the height of the multiple folds on the snap-on tongue 3, the first trim 1 and the second trim 2 can be adaptively balanced to ensure the flatness in the CC direction after assembly. By adjusting the cut edge size of the snap-on tongue 3 inserted in the first slot 11, the flatness in the U / D direction (i.e., the up-down direction or another direction perpendicular to the F / A direction and the CC direction) can be accurately controlled. This process is achieved by adjusting the cut edge of the snap-on tongue 3 in multiple rounds by wire cutting until it is confirmed that the flatness in the U / D direction meets the design requirements.

[0021] Through the above-mentioned assembly, the first trim 1 and the second trim 2 are ensured to be docked with high precision. In the actual vehicle manufacturing process, 95% of the matching accuracy has been achieved within 0.05mm, basically achieving the goal of visual seamless connection.

[0022] In addition, in this embodiment, the base 4 is installed on the outer side of the second decorative part 2, and the base 4 is provided with a hook slot 41. The inner side edge of the second decorative part 2 is provided with a hook 22 for matching the hook slot 41. The hook 22 is hung at the hook slot 41 to fix the base 4 and the second decorative part 2. The inner side of the second decorative part 2 is fixed to the mounting surface of the vehicle sheet metal A through a buckle 5. The back of the second decorative part 2 is provided with a buckle base 23. One end of the buckle 5 matches the mounting hole 51 of the mounting surface of the vehicle sheet metal A. The other end of the buckle 5 is inserted into the buckle base 23, and a waterproof gasket 6 is provided between the buckle 5 and the buckle base 23. Figure 8 shown.
