Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of automobile buffer beam with multiple shock-absorbing function, including support plate 1, the top of support plate 1
Equipped with bearing plate 2, the lower end of bearing plate 2 is equipped with energy-absorbing chamber 3, and the inside of energy-absorbing chamber 3 is equipped with several rubber anti-collision balls 4, and rubber is anti-
The outside of billiards 4 is equipped with caoutchouc elasticity arches 5, and the upper end of bearing plate 2 is equipped with energy-absorbing buffering layer 6, the lower end two sides of energy-absorbing chamber 3 with
It is equipped with the spring 1 of multiple inclination arrangements between support plate 1, guide rod 8, branch are equipped between the middle part and support plate 1 of energy-absorbing chamber 3
The middle part of fagging 1 is equipped with the through-hole passed through for guide rod 8, and is cased with spring on the guide rod 8 between energy-absorbing chamber 3 and support plate 1
2 10, the diameter of spring 2 10 is greater than the diameter of through-hole, and multiple anti-collision air bags 11 are additionally provided between energy-absorbing chamber 3 and support plate 1, prevents
It hits and air feed pump is connected with by appendix 12 on air bag 11, and anti-collision air bag 11 is between spring 1 and guide rod 8, support plate 1
Lower section be equipped with mounting plate 13, and between support plate 1 and mounting plate 13 be equipped with several buffer units.
The buffer unit includes the support rod 14 that 1 lower end of support plate is arranged in and the damping that 13 upper end of mounting plate is arranged in
The inner horizontal of cylinder 15, damping cylinder 15 is equipped with piston 16, and the lower end of support rod 14 extend into the inside of damping cylinder 15 simultaneously
