Technical field
It the utility model is related to auto parts and components processing technique field, more particularly to a kind of honeycomb ramp structure energy-absorption box.
Background technology
With the raising of economic level, automobile increasingly becomes universal family's walking-replacing tool, and security performance is automobile crowd
Soul in more performances, and in terms of security performance, the anticollision of automobile, it is the most important thing again.Before vehicle energy absorption box is vehicle body
One of most important power-absorbing in portion, its front end is connected with bumper, can pass through the plasticity of material during head-on crash
Deform endoergic collision kinetic energy.The energy absorption characteristics and deformation pattern of energy-absorption box determine that vehicle deceleration during head-on crash is rung
Should and power pipeline, the energy-absorbing performance during head-on crash can have important influence to Frontal Crash Safety of HF.
Energy-absorption box one end is bolt-connected on chassis runner, the other end and anticollision girder（Bumper）It is connected, it is every kind of
Energy-absorption box has the impact License Value of itself.When impact is less than License Value, remaining body portion will not in addition to energy-absorption box
Damage；When impact is more than License Value, energy-absorption box also can at utmost absorb energy, reduce the damage of rear portion parts.Inhale
The energy of the longer absorption of length of energy box is more, but length of wagon is restricted, therefore the energy absorption of unit length is very crucial.Separately
Outside, the design of crumple guiding rib and connecting plate also largely influences energy absorption capability.Have at present and much use honeycomb
Come the energy-absorption box that the is improved but only replacement of material can not strengthen energy-absorbing effect in solid, and simply on face, so
Structure still to be optimized.
Utility model content
Purpose of utility model：In order to strengthen the impact resistance security performance of energy-absorption box, it is oblique that the utility model provides a kind of honeycomb
Face structure energy-absorption box, to solve problems of the prior art.
Utility model content：A kind of honeycomb ramp structure energy-absorption box, including cross section are in the energy-absorption box of hollow regular hexagon
Body, energy-absorbing box body connection anticollision girder one end is leading section, connection chassis runner one end is rearward end, energy-absorption box sheet
Body gradually increases along from leading section to rearward end direction thickness, and energy-absorbing box body on the inside of, per two faces facing each other it
Between distance it is equal everywhere；The material for surrounding energy-absorbing box body is substrate, and the substrate material is honeycomb aluminum plate, the energy-absorption box
One group of conquassation groove is distributed with each lateral surface compartment of terrain of body, and two groups of conquassation grooves of any two adjacent exterior sides are dislocatedly distributed.
Preferably, in the substrate face where cellular hexagon bearing of trend, the front and back end with energy-absorbing box body
Portion line direction is parallel.Honeycomb energy-absorbing is collapsed upon the length direction of Cellular Spread, can just play relatively good superposition energy-absorbing effect.
Preferably, the leading section thickness of the energy-absorbing box body is the 65 ~ 87.5% of rearward end thickness.After leading section is arrived
Impact size is born in end gradually to be increased, but should not be excessively greatly different, in order to avoid fracture failure.
Preferably, the mode that the substrate forms energy-absorbing box body is integrated punch forming or welding fabrication.One punching
The intensity that pressure or welding obtain is proper, beneficial to energy-absorbing.
Preferably, two groups of conquassation grooves of the energy-absorbing box body each pair adjacent exterior sides, misplace and are equally spaced.Simultaneously
Conquassation groove location be located exactly at another side conquassation groove middle part so that each several part conquassation probability equal, beneficial to fully absorbing
Impact energy.
Preferably, the conquassation groove is 2 ~ 5 in the quantity of each outside EDS maps of energy-absorbing box body.Conquassation groove should be protected
The structural strength and can guiding crumple of energy-absorption box in itself is demonstrate,proved, it is suitable according to general vehicle situation, quantity 2 ~ 5.
The beneficial effects of the utility model are：The utility model is simple in construction, ingenious in design, guiding crumple efficiency high.
The cross-sectional structure and honeycomb aluminum sheet material of regular hexagon, double regular hexagon Stability Analysis of Structures, intensity is suitable, crumple better performances；Close
Suitable thickness as outside change makes to be oriented to during energy-absorption box crumple accurate, and to rear before energy-absorbing, from inside to outside, and more past inner side energy-absorbing is more
It is more；The substrate intensity and heat dispersion of aluminum alloy material are suitable.The utility model structure design is exquisite, and intensity and crumple performance are excellent
Different, energy absorption curve is good, and unit length impact resistant capability is been significantly enhanced.
