At.Energy-absorption box is securing member important in bumper system for vehicles, and when low speed collision occurs for automobile, bumper beam will be touched
The energy Transmit evenly of middle generation is hit to energy-absorption box, important component of the energy-absorption box as automobile front longitudinal beam front end, master
It acts on and interior energy is exactly converted for the energy generated in collision by crumple, absorb the collision energy that crossbeam transmitting comes, and
The collision energy not fully absorbed is transmitted to chassis runner, so that chassis runner and vehicle safety are protected, current big portion absolutely
Point vehicle has been respectively mounted energy-absorption box.Existing Automobile energy absorption box structure is simple, and weight is big, and structural strength and rigidity are lower, crumple
Effect and energy-absorbing effect are to be improved.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of double-deck three-dimensional polynary origami structure vehicle energy absorption box,
To greatly improve energy-absorbing effect.
A kind of the technical scheme in the invention for solving the above technical problem are as follows: three-dimensional origami structure automobile energy-absorbing
Box comprising energy-absorbing body and ring flange, the energy-absorbing body form the double-deck three-dimensional folding using the static flat-folded double-deck three-dimensional origami structure
Folded cylinder, including the outer energy-absorbing body and interior energy-absorbing body being made of folding unit, the folding unit is isosceles triangle, wherein three
Two angular waists are peak broken line, and bottom edge is paddy broken line, and the cross section of the outer energy-absorbing body is regualr decagon, the interior energy-absorbing body
Cross section is regular hexagon, and interior energy-absorbing body is in outer energy-absorbing body inside center, to form the double-deck three dimensional fold cylinder energy-absorption box.
Further, along six links of axial folding, the triangle base is for the outer energy-absorbing body and interior energy-absorbing body
Connecting line between link.
Further, the bottom edge of the triangle is the side parallel with plane on ring flange.
Further, the outer energy-absorbing body and interior energy-absorbing body are made using aldray material.
Further, the ring flange and double-deck three dimensional fold cylinder one end are affixed, and are consolidated energy-absorption box by bolt
It is scheduled on Chinese herbaceous peony stringer.
Compared with prior art, the advantages of the utility model has are as follows: the utility model is a kind of novel automobile energy-absorbing
Box structure, the three-dimensional cylinder of bilayer that the energy-absorption box of the utility model is formed using origami structure, folds in each isosceles triangle
It is crosslinked locking under the supporting role of unit, makes energy-absorption box that there is good static strength and rigidity using triangle stability principle,
Structure is set to be difficult to be twisted or be bent in normal conditions；Using energy-absorbing body made from aldray material there is energy-absorption box
Higher crumple intensity；And when axially bearing low speed collision, the folding line of structure plays the work of good crumple induction
With so that reaching induction energy-absorption box occurs ideal Folding Deformation, absorption collision energy, as much as possible reduction impact force pair
The damage of chassis runner, and then guarantee the safety of occupant.
Detailed description of the invention
Fig. 1 is the utility model schematic perspective view；
Fig. 2 is the utility model section figure.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.A kind of three-dimensional origami structure as shown in Figure 1, 2
