[0038] In this embodiment, the decorative strip 12 and the lower decorative strip 13 cooperate with each other, and the appearance is decorated by spray painting, chrome plating and other processes to enrich the decorative effect of the air intake grille while satisfying its air intake function.

[0039] In this embodiment, the frame connection structure 2 includes a triangular connecting frame 21, and the triangular connecting frame 21 is provided with a baffle 211, a connecting plate 212 and a supporting base plate 213. The baffle 211 is in contact with the vehicle body, and the side of the connecting plate 212 is connected to the baffle 211, and the bottom of the connecting plate 212 is fixedly connected to the supporting base plate 213. The side of the supporting base plate 213 is fixedly connected to the frame 11. The side baffles 211 can limit the position of the frame 11 from both sides after the positioning and installation of the frame 11 is completed, so that the position of the frame 11 will not be easily cheap. The connecting plate 212 is set to connect the frame 11 and the outer frame 5 to each other. At the same time, the triangular connecting frame 21 is extended outward from the main body of the frame 11, which can achieve the purpose of connecting the frame 11 and the outer frame 5 without increasing the area of ​​the frame 11.

[0040] In this embodiment, a rectangular hole 2121 and a waist-shaped hole 2122 are provided on the connecting plate 212. The rectangular hole 2121 and the waist-shaped hole 2122 are arranged side by side in the horizontal direction. The rectangular hole 2121 is positioned and connected to the positioning column on the outer frame 5, and the waist-shaped hole 2122 is positioned and connected to the screw column on the outer frame 5.

A hook 223 is provided on the outer side wall of the positioning groove 221. The positioning groove 221 is set to be concave from the outside to the inside. Such a shape facilitates the bolt to lock the decorative strip 12 from the inside of the frame 11 to the outside, and at the same time makes the head of the bolt located on the inner side of the frame 11 to prevent affecting the appearance of the decorative strip 12.

[0043] In this embodiment, the positioning clip 222 can fix the frame 11 to an external mounting structure such as a vehicle body, an outer frame 5, etc. through the hook 223. Because the positioning clip 222 and the positioning groove 221 are located close to each other, it is convenient to install the hook 223 and the bolt at the same time during assembly.

[0044] In this embodiment, a hollow hole 215 is provided at the connection between the support base plate 213 and the frame 11, and an inclined support plate 216 is provided above the hollow hole 215. One end of the inclined support plate 216 is against the frame 11, and the other end is against the side of the connecting plate 212. Through the hollow hole 215, the connection strength of the root of the triangular connecting frame 21 can be reduced, making it easier to break from the hollow hole 215. When a collision with a pedestrian occurs, it is convenient to protect the pedestrian by breaking.

[0045] In this embodiment, the inclined support plate 216 is provided to support the side of the triangular connecting frame 21 from the side, so that when the triangular connecting frame 21 is deformed, it is easier to break downward at the hollow hole 215 due to the support of the inclined support plate 216, rather than breaking in a direction other than downward. This can prevent the broken triangular connecting frame 21 from causing secondary injuries to pedestrians.

[0046] In this embodiment, the decorative strip connecting structure 3 includes a double-row buckle 31 and a connecting column arranged on the decorative strip 12. The double-row buckle 31 is respectively arranged on the upper and lower edges of the decorative strip 12. The connecting column is fixedly connected to the frame 11 by bolts. The double-row buckle 31 limits the position of the decorative strip 12 from the upper and lower directions to prevent the decorative strip 12 from loosening due to external environments such as long-term exposure to sunlight and rain, which may affect the decorative effect and may also block the air inlet and affect the air intake function.

[0047] In this embodiment, the decorative strip connection structure 3 also includes a plurality of positioning support blocks 32 arranged on the frame 11, the positioning support blocks 32 protrude from the installation groove of the decorative strip 12, and a safety groove 321 and an abutment column 322 are arranged on the positioning support blocks 32, and the outer end of the abutment column 322 abuts on the decorative strip 12, and the positioning support blocks 32 do not directly contact the decorative strip 12, but contact it through the abutment column 322, while limiting the position of the decorative strip 12, the supporting strength of the decorative strip 12 is reduced, and when a collision occurs, it is easier to deform inward and absorb energy. At the same time, an overly violent collision will also cause the decorative strip 12 to directly contact the positioning support blocks 32, thereby limiting further deformation of the decorative strip 12 and preventing direct breakage, which would cause secondary injury to pedestrians.

[0048] In this embodiment, the lower decorative strip connection structure 4 includes a positioning piece 41, a grooved piece 42 and a fixed connecting piece 43 arranged on the lower decorative strip 13, the positioning piece 41 is arranged on the upper edge of the lower decorative strip 13, the grooved piece 42 is arranged on the lower edge of the lower decorative strip 13, and the fixed connecting piece 42 is arranged at both ends of the lower edge of the lower decorative strip 13, the lower decorative strip connection structure 4 also includes a snap-in piece 44 and a limiting piece 45 arranged on the decorative strip 12, the snap-in piece 44 is snap-fittedly connected with the grooved piece 42, the limiting piece 45 abuts against the lower edge of the lower decorative strip 13, and a push rod 46 is further provided on the decorative strip 12, the push rod 46 abuts against the inner side surface of the lower decorative strip 13, the positioning of the lower decorative strip 13 and the decorative strip 12 can be achieved by connecting the positioning piece 41 with the decorative strip 12, the push rod 46 is arranged in direct contact with the lower decorative strip 13, and can lift the lower decorative strip from the inside to the outside to prevent the lower decorative strip 13 from deforming.
