This solution uses the trim cover mounting bracket 1 as the basic component. During actual assembly, the trim cover mounting bracket 1 is first assembled and fixed on the vehicle body 40, and then the hinge trim cover 2 is assembled to achieve the function of overall covering and shielding.

[0051] It should be noted that the orientation word "outer side" used above and the orientation word "inner side" used below are defined with the vehicle body as the description reference. That is, the side close to the vehicle body center line is the "inner side", and the side far from the vehicle body center line is the "outer side"; it should be understood that the use of the above orientation words is only for clearly explaining the relative position relationship of the components and structures in this solution and does not form a restrictive interpretation of this solution.

[0052] In this article, "vehicle body sheet metal" refers to the vehicle body structure at the corresponding installation position, and the vehicle body structure is formed by sheet metal processing.

[0053] Please refer to Figure 6 , Figure 7 and Figure 8 , among which, Figure 6 and Figure 7 respectively show the structure of the trim cover mounting bracket 1 from different angles, Figure 8 is a structural schematic diagram of the hinge trim cover 2. It can be understood that the assembly relationships of the tailgate hinges on both sides are left-right mirror images, and the structural adaptation principles are the same. Therefore, only the trim cover assembly configured on the left hinge 10 is used as the description main body for detailed description in this article.

[0054] Combined with Figure 6 and Figure 7As shown, the body of the trim cover mounting bracket 1 includes a vertically extending portion 11 and a horizontally extending portion 12. Two positioning pins 13 are provided on the trim cover mounting bracket 1 and are adapted to the pin holes 41 formed on the body sheet metal to form a positioning pin connection structure; at the same time, a buckle 14 is provided on the trim cover mounting bracket 1 and is adapted to the buckle holes 42 formed on the body sheet metal to form a buckle connection structure; and a first through hole 15 is formed on the trim cover mounting bracket 1 and is adapted to the first threaded hole 43 formed on the body sheet metal and the first threaded fastener 61 to form a first threaded connection structure. Here, the positioning pin connection structure, the buckle connection structure and the first threaded connection structure are used to realize the detachable connection between the trim cover mounting bracket 1 and the vehicle body 40.

[0055] Combined with Figure 8 As shown, the body of the hinge trim cover 2 includes a bottom cover 21, an outer cover 22 and an inner cover 23. A first bayonet 24 is provided on the hinge trim cover 2 and is adapted to the first hook 16 provided on the trim cover mounting bracket 1 to form a first snap connection structure; at the same time, a second through hole 25 is formed on the hinge trim cover 2 and is adapted to the second threaded hole 44 formed on the body sheet metal and the second threaded fastener 62 to form a second threaded connection structure. Here, the first snap connection structure and the second threaded connection structure are used to realize the detachable connection between the hinge trim cover 2 and the trim cover mounting bracket 1 and the vehicle body 40.

[0056] In addition, as Figure 6 shown, a second hook 17 is provided on the horizontally extending portion 12 of the trim cover mounting bracket 1 and is adapted to the second bayonet 51 on the rear bumper 50 to form a second snap connection structure.

[0057] Furthermore, a third hook 26 is provided on the bottom cover 21 of the hinge trim cover 2 and is adapted to the third bayonet 52 on the rear bumper 50 to form a third snap connection structure.

[0058] Next, the specific implementation method will be described in detail in combination with the assembly sequence of the trim cover mounting bracket 1 and the hinge trim cover 2.

[0060] First, as Figure 4 shown, two pin holes 41 and two first threaded holes 43 are formed on the body sheet metal; among them, the two pin holes 41 are respectively inserted and adapted to the positioning pins 13 on the trim cover mounting bracket 1 so that the trim cover mounting bracket 1 is positioned with the body sheet metal. After positioning the two, the first through hole 15 on the trim cover mounting bracket 1 is aligned with the first threaded hole 43, and two first threaded fasteners 61 are respectively inserted into the corresponding holes and tightened to complete the assembly between the basic component trim cover mounting bracket 1 and the vehicle body.

[0061] Please refer toFigure 9 , which shows a schematic diagram of the assembled state of the trim cover mounting bracket 1. As shown in the figure, after assembly, the vertical extension 11 of the trim cover mounting bracket 1 covers the vehicle body sheet metal outside the hinge 10, and its horizontal extension 12 covers the vehicle body sheet metal below the hinge 10. In this solution, a positioning pin connection structure, a snap connection structure, and a first threaded connection structure are arranged between the trim cover mounting bracket 1 and the vehicle body 40 to form a detachable fixed connection.

[0062] Specifically, a waterproof foam needs to be fixed at the bottom of the positioning pin 13 to prevent rainwater from flowing into the vehicle body sheet metal through the pin hole 41 during rain, causing rust.

[0063] It can be understood that in other specific implementations, either the positioning pin connection structure or the first threaded connection structure can be selected, and the detachable fixed connection between the two can also be achieved. Comparatively speaking, in this solution, the positioning pin connection structure is first used to achieve the assembly positioning of the trim cover mounting bracket 1, then the snap connection structure is used to form a basic fixation between the two, and finally the first threaded connection structure is used to fix the trim cover mounting bracket 1, which can effectively balance the assembly processability and the reliable fixed connection relationship.

[0064] Preferably, both the positioning pin connection structure and the first threaded connection structure are set to two groups, and are respectively arranged between the vertical extension 11 and the vehicle body sheet metal and between the horizontal extension 12 and the vehicle body sheet metal. Through a smaller number of connection structures, reliable positioning and fixing relationships can be formed on the vertical extension 11 and the horizontal extension 12 respectively.

[0065] II. Assembly of the rear bumper.

[0066] Please refer to Figure 10 and Figure 11 together, where Figure 10 is a schematic diagram of the assembled state of the rear bumper, Figure 11 is Figure 10 an enlarged view of part D of
