When be connected with;Taper prism energy-absorption bracket is near undaform energy-absorbing baffle plate one end, the circular arc that upper and lower plates have, end face
Both sides are respectively welded rectangular slab, and open bolt hole, for being connected with described fixed plate;Taper prism energy-absorption bracket is near car
Body one end, bending upwards, and are connected with vehicle frame.
Preferably, the inside packing material of described taper prism energy-absorption bracket is being in refer to away from car body direction upper density
Number gradient is successively decreased.
Beneficial effects of the present invention are as follows:
First, undaform energy-absorbing baffle plate, is rectangular box structure, increase making contact area, reduction impact pressure, and effectively
Prevent kart from piercing truck bottom.Undaform energy-absorbing baffle plate front waveform plate when colliding, compared with rectangular tube or
Flat board is more yielding, can effectively reduce initial spike stress when colliding.The absorbable collision of the deformation of waveform plate simultaneously is produced
Raw energy, increases energy absorption characteristics.Be stamped to form using aluminium, steel it is soft mutually and, with good crash-worthiness and energy absorption
Effect.Following on undaform energy-absorbing baffle plate back panel to bend to undaform energy-absorbing baffle interior, there are certain circularity, phase in corner
Inside is folded to below for upper, increases the intensity of corner when collision occurs, be not result in fracture.Undaform energy-absorbing baffle plate is anti-
Panel is stamped with two indent faces of cylinder, is connected with energy-absorbing filling cylinder is supported, two can be made to build even closer being connected to
Together, reach firm connection.
2nd, undaform energy-absorbing baffle interior be filled with density gradient metal foam, and along away from car body direction density gradually
Successively decrease.Density gradient filled and process has the premium properties such as porosity is high, wall intensity is high, specific stiffness is big.When a collision occurs, no
Only so that impulsive force is presented graded in collision process, and filled and process can progressively absorb a large amount of energy that collision is produced
Amount.Additionally, filled and process can reduce the weight of device under conditions of energy-absorbing is increased, density gradient can save metal foam material
Material.Also, as density constantly increases, the Compressive Mechanical Properties and energy absorption capacity of filled and process are significantly improved, impact strength
Also increase therewith, so as to further improve energy absorption capability, form exponential gradient energy-absorbing effect.Undaform energy-absorbing baffle plate with it is interior
Portion's filling is collectively forming low energy-absorbing region.Collision energy during absorbable slight impact, and effectively reduce peak stress.
3rd, together, two sides closed plate can snap in positive and negative plate to undaform energy-absorbing baffle plate positive and negative panel rivet interlacement
It is fixed in the groove on side, realize the assembling of undaform energy-absorbing baffle plate body.It is this to design the assembling for being beneficial to undaform energy-absorbing baffle plate
With dismounting, the part for damaging is caused when can change slight impact in time, use cost is advantageously reduced.
4th, energy-absorbing filling cylinder is supported to be made up of two-phase high intensity cold steel rolling HC340/DP590 materials, two-phase high intensity cold
Between 500MPa to 1500MPa, the high intensity that material has further enhances the stable connection of cylinder to the intensity of steel rolling
Property.Meanwhile, two-phase high intensity cold steel rolling has fine energy absorption capacity, and low-density and high-strength characteristic, the lightweight of equality circuit
Require.Energy-absorbing filling cylinder interior is supported to be filled with polyurethane foam plastics, polyurethane foam plastics has splendid elastic, soft
Soft, percentage elongation and compressive strength.Polyurethane foam plastics is filled in support energy-absorbing filling cylinder, which can not only be improved
Support rigidity, makes whole device be hardly damaged in an impact, and can absorb a large amount of impact energies in cylinder clashes into BENDING PROCESS

Amount of energy is big.Additionally, energy-absorbing filling drum forms play stable connection undaform energy-absorbing baffle plate and support bracket fastened effect.
5th, fixed plate adopts two-phase high intensity cold steel rolling HC400/DP780 materials, and intensity and toughness is larger, makes support energy-absorbing
Connect between filling cylinder and taper prism energy-absorption bracket and more consolidate.Collide it is violent when, can undaform energy-absorbing baffle plate with
Support energy-absorbing filling cylinder impact force to be further transferred on taper prism energy-absorption bracket after conquassation, touch so as to continue absorption
Hit energy.The face of cylinder is stamped out in the middle part of fixed plate, shape is matched with the face of cylinder for supporting energy-absorbing filling cylinder, and is connected to one
Rise, compare with flat board with cylindrical drum connection, improved structure connection is more consolidated.
6th, taper prism energy-absorption bracket is made using carbon fibre material so as to lightweight, the high characteristic of intensity.This
Outward, filled polyolefin elastomer POE materials inside taper prism, and its density is made near the exponentially gradient change of vehicle body direction
Change, when which is subjected to impact so as to which stress changes in gradient so as to which energy-absorbing gradient increases.Also, POE materials have higher
Bending strength and shock resistance, high ratio energy absorption characteristics so as to impact force is dispersed in whole packing material, so as to enter
One step improves its buffering energy-absorbing;POE packing material low cost of manufactures, so as to also reduce the cost of anticollision device, collision-prevention device.Additionally, taper
Prism energy-absorption bracket can also effectively reduce the initial spike of impact force, the in-car member security of protection.Outside packing material and carbon fiber
Shell cooperates, and can absorb the energy that a large amount of collisions are produced, forms high energy-absorbing region.So as to significantly less collision is to kart
Injury, effectively prevent car from piercing bulk production chassis.Fixed support is formed with two half-shell docking, is conducive to assembling and is torn open
Unload, support damaging part is changed with timely, and be easy to fill POE materials to internal stent.
7th, it is different from filling energy absorption capacity according to material, by whole device along away from being divided into three energy-absorbings on car body direction
Region.The low energy-absorbing region of outermost is easier to deform when there is slight impact, absorbs collision energy;When collision more play
In the case of strong, after low energy-absorbing region is by conquassation, waveform energy-absorbing baffle plate back panel intensity is big, is unlikely to deform, will can collide
Power is delivered to middle energy-absorbing region.In middle energy-absorbing region, energy-absorbing filling cylinder and internal packing material is supported laterally to be pressed
Contracting, deforms upon, and can absorb collision energy, and the energy absorption capacity in middle energy-absorbing region is more than low energy-absorbing region energy absorption capacity;If middle
After energy-absorbing filling cylinder is supported by conquassation, impact force can be transmitted to taper prism energy-absorption bracket by fixed plate, used as high suction
Energy region, taper prism energy-absorption bracket and internal packing material are axially compressed, because high energy-absorbing regional structure intensity is big, filling
Material energy absorption is optimal, and after low, middle energy-absorbing region energy absorption is by conquassation, high energy-absorbing region can absorb remaining impact energy
