Description of drawings:
Accompanying drawing 1 is a new automobile bumper/spoiler schematic diagram.
Accompanying drawing 2 is that the new automobile bumper/spoiler is assemblied in the scheme drawing on the roadlice.
The specific embodiment:
As shown in Figure 1, the new automobile bumper/spoiler is made of back steel plate 15, front spring 2, piston 8 and piston sleeve 11, connecting rod 6 and piston return spring 4; Between the steel plate of front and back six parallel piston type slip joints are arranged, back steel plate 15 is fixed in automobile chassis frame 14 front ends, the affixed piston sleeve 11 in the front of back steel plate 15, piston 8 is installed in the piston sleeve 11, there is cooresponding connecting rod pivot pin frame 5 front of piston and the back of front spring, and there is pin hole at the two ends of connecting rod 6, and the two ends of connecting rod 6 are inserted in the connecting rod pivot pin frame 5 of piston front and front spring back, plug the connecting rod pivot pin again, piston 8 and front spring 2 are coupled together; When automobile met accident bump, front spring 2 moved backward, promoted piston 8 by connecting rod 6 and moved backward, and the air in the compression piston sleeve 11 makes it to go out from a deflation hole of piston sleeve 11 bottoms, thereby automobile impact force is all assimilated.
Back steel plate 15 has a skirt section 12 forward, and there is a brace panel 13 its back, and this is in order to strengthen the rigidity of back steel plate, and is not yielding when meeting accident bump; There are two engine beds 10 in described skirt section 12, and at affixed two the front spring location hooks 9 up and down of the midway location of all two adjacent piston type slip joints, front spring location hook 9 has the arrow of turning 90 degree, and the arrow of upper skirt is downward, and the arrow of skirt end upwards.
