Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Figure is referred to, in the utility model embodiment, a kind of automotive bumper, including buffer board 1, the and of side protective plate 2
Leaf spring 3；The left and right two ends of the protective plate 2 are provided with side protective plate 2, and side protective plate 2 is arcuate structure, and buffer board 1 is prevented with side
Backplate 2 is structure as a whole, and leaf spring 3 is fixedly connected on the inner side of buffer board 1, and the inside lateral bend of leaf spring 3 is (interior described in specification
Side is the top shown in accompanying drawing), the ultimate range between leaf spring 3 and buffer board 1 is 80~120mm, and the inner side of leaf spring 3 is set
There is the supporting plate 5 parallel with buffer board 1, supporting plate 5 is U-shaped steel, and two symmetrical reinforcements 15 are provided with supporting plate 5, plus
Strong muscle 15 is horizontally disposed along supporting plate 5, strengthens the intensity of supporting plate 5, and fix bar is fixedly connected between supporting plate 5 and leaf spring 3
13, supporting plate 5 is pressed leaf spring 3, the both sides of the supporting plate 5 are fixedly connected with spring 4, and the other end of spring 4 is fixed and connected
It is connected on leaf spring 3, cushioning effect is played when supporting plate 5 compresses leaf spring 3；Be provided with the inner side of the supporting plate 5 two it is right
The first rotating shaft 6 of title, rotates connection first connecting rod 7 in first rotating shaft 6, second turn is provided with the other end of first connecting rod 7
Axle 8, the second rotating shaft 8 rotates connection second connecting rod 9, and second connecting rod 9 is rotatably connected on car body 16 by hinge 10；In the car
