The movement of pipe, when the power suffered by the energy absorbing members disappears, the pressure mouth pipe makes volume by natural resiliency to the pipe crimping reaction
Pipe is restored to original state.The pipe crimping 9 is mono-layer tube when 3 normal condition of energy absorbing members, when upper bearing plate 5 and lower bearing plate 6
When stress, 9 lateral ends of pipe crimping generally move from lower to upper under the effect of contraction of pressure mouth pipe 10, to make pipe crimping 9 by list
Layer is tubular to become bimetallic tube.When upper bearing plate 5 and lower bearing plate 6 do not have active force, due to pressing the reaction of mouth pipe 10, pipe crimping 9
Lateral ends generally move from top to bottom, and pipe crimping 9 is formed as mono-layer tube by bimetallic tube, and so cycle reaches the work of buffering energy-absorbing
With.
The Ith grade of safeguard structure includes V-type plate 1, by impact caused by land mine or the explosion of other explosives
When wave, make energy-bias, reduces damage of the shock wave energy to car bottom.The V-type plate 1 is detachably connected with vehicle floor 4
And it is longitudinally disposed along vehicle floor 4.
Energy absorbing members are located in V-type plate 1, and the energy absorbing members 3 are detachably connected with vehicle floor 4.
The Ith grade of safeguard structure, the IIth grade of safeguard structure and the IIIth grade of safeguard structure are along 1 longitudinal centre line two of V-type plate
Side is symmetrical, and in order to improve the protective capacities of entire vehicle bottom, the IIth grade of safeguard structure and the IIIth grade of safeguard structure are along vehicle bottom
The setting of 4 longitudinal centre line of plate is multiple.
The IIth grade of protection is metal circular tube 2, and the metal circular tube 2 is arranged in multilayer, round metal between layers
Pipe 2 is arranged in a manner of tangent.Metal circular tube 2 is high duty metal pipe, and after V-type plate 1 disperses some energy or the Ith grade anti-
After shield is damaged by shock wave, energy reaches the metal circular tube 2 of high intensity, and 2 structure of metal circular tube is by being crushed, deforming absorbable punching
Hit the energy of wave generation.
One tablet is set between the energy absorbing members 3 and metal circular tube 2, on the upper bearing plate 5 and the lower bearing plate 6
