It should be understood that the preferred embodiments are only for the purpose of illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0033] This embodiment provides a decorative cover plate for a car back door hinge, such as Figure 1 and Figure 2As shown, a back door hinge decorative cover structure of the present invention includes a cover body 1, a cover soft glue 2, and foam 3. The cover body 1 and the cover soft glue 2 are connected by a secondary injection molding process.

[0034] like Figure 2 and Figure 3 As shown, the mounting surface of the cover body 1 is provided with pre-installation clips 101 and 102. These clips 101 and 102 serve as pre-installation and pre-positioning for the vehicle in the X-direction, limiting the X-direction freedom of the cover body 1. The cover body 1 is provided with a soft cover adhesive 2. When the cover body 1 is installed on the body sheet metal 4, the soft cover adhesive 2 envelops the body sheet metal 4 and adheres tightly to the body sheet metal 4. In this embodiment, the body sheet metal 4 is the sheet metal on the back door.

[0035] The soft cover rubber 2 is interference-matched with the sheet metal 4. This absorbs any tolerances between the cover body and the sheet metal, ensuring a tight fit between the tailgate hinge cover and the sheet metal, preventing leaks that could affect the appearance. Ribs 110 are provided on the mounting surface of the cover body 1 to strengthen it and prevent severe deformation after injection molding.

[0036] like Figure 2 and Figure 4 As shown, the mounting surface of the cover body 1 is provided with a limit plate 103 and a limit plate 104, which are respectively located on the two side surfaces of the vehicle body sheet metal 4 in the Y direction and are clearance-matched with the vehicle body sheet metal 4 to achieve pre-limitation of the cover body 1 in the Y direction and limit the Y-direction freedom of the cover body 1.

[0037] like Figure 2 and Figure 5 As shown, the cover body 1 is equipped with limit supports 105, 106, and 107. Foam pads 3 with self-adhesive backing are attached to the vehicle body sheet metal 4. Limit supports 105, 106, and 107 serve as auxiliary supports and pre-positioning in the Z direction of the vehicle, limiting the Z-direction freedom of the cover body 1. The interference contact between the foam pads 3 and the vehicle body sheet metal 4 prevents abnormal noise from the cover and also acts as a buffer.

[0038] like Figure 2 and Figure 6 As shown, the back of the cover body 1 is provided with a clamping member 108 and a clamping member 109. The clamping members 108 and 109 respectively engage with corresponding slots 401 arranged on the vehicle body sheet metal 4 to provide a clamping and fastening function. On the back of the cover body 1, outwardly protruding bosses 111 and 112 are provided at corresponding positions of the clamping members 108 and 109, respectively, to remind the operator of the assembly position.

[0039] Assembly principle: Before the tailgate hinge decorative cover is installed on the vehicle, the cover soft rubber 2 and the cover body 1 are first connected into a whole through a secondary injection molding process. Then the foam 3 is respectively adhered to the limit support 105, limit support 106 and limit support 107 using its own adhesive. When the tailgate hinge decorative cover is installed on the vehicle, the pre-installed clips 101 and 102 are first rotated from bottom to top along the clip direction to the structural limit position, and the limit plates 103 and 104 are simultaneously dropped into the two sides of the vehicle body sheet metal 4 in the Y direction. Then, the limit supports 105, 106 and 107 are naturally dropped onto the surface of the matching vehicle body sheet metal 4. Finally, the bosses 111 and 112 are pressed perpendicularly to the surface of the cover so that the clips 108 and 109 fall into the corresponding slots 401, completing the fastening of the tailgate hinge decorative cover.

[0040] The X, Y, and Z directions in this embodiment are all based on the vehicle coordinate system.

[0041] This embodiment also provides a method for installing a car back door hinge decorative cover, specifically:

[0042] S1: Rotate the pre-installed buckle from bottom to top along the buckle direction and push it to the bottom limit position. At the same time, place the limit plates on both sides of the body sheet metal in the Y direction.

[0043] S2: Make the limit support overlap the surface of the body sheet metal;

[0044] S3: Press the protrusion on the soft rubber of the cover in a direction perpendicular to the surface of the cover body. The position of the protrusion corresponds to the position of the clip, so that the clip is clipped into the slot.

[0045] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
