Embodiment 1
[0022] figure 1 The structure of Embodiment 1 of the present invention is shown. The automobile bumper with energy absorption and pedestrian protection device in this embodiment mainly consists of a decorative layer 1, a reinforcing plate 9, N damping units 3, N+1 rhombic mechanisms 4, It is composed of 2N+2 connecting plates 5, and N is a natural number. The rhombus mechanism 4 is connected with the damping unit 3 at intervals in sequence; among the other two vertices of each rhombus mechanism 4, one is installed on the reinforcing plate 9 through the connecting plate 5, and the other is installed on the front end 2 of the automobile bottom axle through the connecting plate 5 superior. Both the rhombic mechanism 4 and the damping unit 3 and the rhombic mechanism 4 and the connecting plate 5 are connected by hinge units 6 . The decorative layer 1 is installed on the reinforcing plate 9 .
[0023] The decorative layer 1 can be made of elastic materials such as plastic or rub...
Embodiment 2
[0026] image 3 The structure of another embodiment of the present invention is shown. In this embodiment, the automobile bumper with energy-absorbing and pedestrian protection device mainly consists of a decorative layer 1, a reinforcing plate 9, N connecting rods 8, and 2N+2 damping units 3. It is composed of N+1 diamond-shaped mechanisms 4 and 2N+2 connecting plates 5, where N is a natural number. The rhombus mechanism 4 is connected with the connecting rod 8 at intervals in sequence; among the other two apexes of each rhombus mechanism 4, one is installed on the reinforcing plate 9 through the connecting plate 5, and the other is installed on the front end 2 of the automobile bottom axle of the automobile through the connecting plate 5. superior. A damping unit 3 is installed between the opposite two vertices of each rhombus mechanism 4, between the rhombus mechanism 4 and the connecting rod 8, between the rhombus mechanism 4 and the damping unit 3 and between the rhombus...
