[0037] Embodiment 1:

[0038] Since the existing bumper cannot meet the installation requirements of the decorative part without affecting its appearance, based on this, this embodiment provides an installation structure for the front bumper and the grille decorative part. As shown in Figure 1(a) and Figure 2 shown, it includes a front bumper body 100, a connecting plate 200, and a grille decorative part 300. By adding a connecting plate 200 between the front bumper body 100 and the grille decorative part 300, the limitation of the installation structure on the shape of the front bumper body 100 is reduced, making the shape and the layout of the grille decorative part 300 more flexible.

[0039] Specifically, in combination with Figure 2 and Figure 3As shown in the figure, the front bumper body 100 is provided with a plurality of air intake holes 102. The air intake holes 102 are strip-shaped holes, and their length direction is arranged along the vehicle body height direction (i.e., the Z direction); a fixed flange 101 is arranged along the edge of the air intake hole 102. The fixed flange 101 protrudes from the surface of the front bumper body 100 to form an annular closed structure; and the fixed flange 101 is perpendicular to the appearance surface of the front bumper body 100. When the connecting plate 200 is assembled with the front bumper body 100, the fixed flange 101 provides a limiting function for the connecting plate 200 and the grille decorative part 300 in the left-right direction (i.e., the Y direction).

[0040] In order to cooperate with the fixed flange 101, the connecting plate 200 is provided with a groove 240 corresponding to the air intake hole 102. The arrangement of the groove 240 is as Figure 4 shown. The left and right two mating surfaces inside the groove 240 are provided with first limiting ribs 230. The first limiting ribs 230 are horizontally arranged, and a plurality of first limiting ribs 230 are distributed on the inner wall of the groove 240; when the connecting plate 200 is matched with the front bumper body 100, the fixed flange 101 is inserted into the groove 240, and the first limiting ribs 230 combine with the insertion of the fixed flange 101 and the groove 240, and at the same time limit the connecting plate 200 in the front-rear direction and the left-right direction of the vehicle.

[0041] It should be noted that the front, rear, left, and right in this embodiment are referenced with the vehicle direction.

[0042] A boss 210 is arranged between adjacent grooves 240. Combining Figure 4 and Figure 8 shown, the boss 210 is attached to the front bumper body 100, and the boss 210 is connected to the front bumper body 100 by ultrasonic welding to increase the reliability of this structure. The shape of the boss 210 can be set according to the actual connection strength and layout space. In this embodiment, the cross-section of the boss 210 is rectangular, which can ensure the contact area between the boss 210 and the front bumper body 100.

[0043] A plurality of side cantilever claws 220 are arranged at the edge of the groove 240. Through the cooperation of the plurality of side cantilever claws 220 and the clamping holes 310 on the grille decorative part 300, the connection between the connecting plate 200 and the grille decorative part is realized. Combining Figure 5 and shown in Figure 7, the side cantilever claw 220 includes a claw body, a claw head 221 and a second limiting rib 224. The claw body has a certain height; in order to make the side cantilever claw 220 easy to enter the clamping hole 310, the top of the claw body (referenced by Figure 5 the shown direction) is provided with an inclined surface, which can guide the side cantilever claw 220 to enter the clamping hole 310.

[0044] One side of the jaw body is provided with a jaw head 221, and the jaw head 221 protrudes from the surface of the clamping body; several second limiting ribs 224 are arranged on the other side of the jaw body. The second limiting ribs 224 and the jaw head 221 can jointly limit the connecting plate 200 in both the X direction and the Y direction; wherein, the X direction refers to the front-back direction of the vehicle, and the Y direction refers to the left-right direction of the vehicle.

[0045] Specifically, the top of the jaw head 221 has an inclined surface, which also has a guiding function; the longitudinal section of the jaw head 221 is triangular or trapezoidal. In this embodiment, two second limiting ribs 224 are arranged on the jaw body, and the second limiting ribs 224 are arranged near the end of the jaw body. The two second limiting ribs 224 are symmetrically arranged relative to the jaw head 221. By abutting the side wall of the second limiting rib 224 against the clamping hole 310, the Y-direction limit is achieved.

[0046] As Figure 5 Shown in FIGS. 7(a) and 7(b), the second limiting rib 224 is arranged on the back of the jaw body, and it is a stepped structure. The stepped surface formed by the second limiting rib 224 is the supporting surface 223. The supporting surface 223 and the bottom surface of the jaw head 221 are at different heights. Among them, the bottom surface of the jaw head 221 is located above the supporting surface 223. When the side cantilever jaw 220 is inserted into the clamping hole 310, the bottom surface of the jaw head 221 contacts one side surface of the grille trim 300, and the supporting surface 223 contacts the other side surface of the grille trim 300, thereby forming an effective limit in the X direction and ensuring the connection reliability between the grille trim 300 and the connecting plate 200.

[0047] According to the view directions of FIGS. 7(a) and 7(b), a guiding surface 222 is arranged at the top end of the second limiting rib 224. The guiding surface 222 is an inclined surface, and its inclined direction is opposite to the inclined direction of the top surface of the jaw body; the connecting surface between the guiding surface 222 and the supporting surface 223 is a vertical surface.

[0048] Combined with FIGS. 1(b), 7(a) and 7(b), when the grille trim 300 is assembled with the connecting plate 200, the side cantilever jaw 220 is inserted into the clamping hole 310. The jaw head 221 cooperates with the clamping hole 310 in the front-back direction of the vehicle to limit the grille trim 300 from slipping out towards the rear of the vehicle; the supporting surface 223 of the second limiting rib 224 also cooperates with the clamping hole 310 in the front-back direction of the vehicle to limit the grille trim 300 from moving forward. The vertical surface of the second limiting rib 224 cooperates with the side wall of the clamping hole 310 in the Y direction to limit the grille trim 300 from moving laterally in the vehicle. Therefore, after the side cantilever jaw 220 is inserted into the clamping hole 310, it can ensure the reliable connection between the connecting plate 200 and the grille trim 300.

[0049] In this embodiment, cross positioning posts (not marked in the figure) are provided on the back of the front bumper body 100. The positioning posts can be set at positions corresponding to the front of the front bumper body 100 where there are obstructions such as the vehicle logo position, or at the upper boundary position of the front bumper body 100. Setting the positioning posts at these positions can prevent defects such as shrinkage and deformation on the front of the front bumper body 100 from being exposed. Positioning holes are provided at positions corresponding to the positioning posts on the connecting plate 200. When the positioning posts are inserted and matched with the positioning holes, the positioning posts play a role in limiting the connecting plate 200 in the up-down direction of the vehicle.

[0050] It can be understood that in other embodiments, the positioning posts can also be set on the connecting plate 200, and the positioning holes are set on the grille decorative part 300, which can also achieve the purpose of restricting the grille decorative part 300 from moving in the up-down direction of the vehicle.

[0051] In this embodiment, the connecting plate 200 is matched with the fixed flange 101 of the front bumper body 100 through the groove 240 and the first limiting rib 230. At the same time, the connecting plate 200 is matched with the grille decorative part 300 through the side cantilever claws 220, which ensures the connection stability of the front bumper body 100, the connecting plate 200 and the grille decorative part 300; by adding the connecting plate 200 between the front bumper body 100 and the grille decorative part 300, the limitation of the installation structure on the shape of the front bumper body 100 is reduced, and the connecting plate 200 is welded to the front bumper body 100 at the boss 210 position, increasing the overall strength of the front bumper surface.

[0052] This embodiment not only ensures the installation requirements of the grille decorative part 300, but also can improve the decorative effect of the front bumper and has a reliable structure.
