Meeting place, addition circular configuration is constituted again.
Compared to the prior art, the beneficial effects of the utility model are:
1. initial stage relies on bending deformation energy-absorbing, initial spike power can be effectively reduced, protects occupant safety.
The energy-absorbing box device of the utility model, it is staggered due to round tube layer by layer so that collision initial stage mainly by
The bending deformation of hexagonal plate structure absorbs energy, can reduce the size of initial spike power in this way, touch to reduce as far as possible
Hit injury of the acceleration to passenger.
2. the setting of hierarchical structure effectively improves uptake, guarantee energy absorbing efficiency, and collisional stabilization is strong.
It is interspersed between the honeycomb and plate of the inside filling of two hexagonal plates up and down involved in the utility model small
Round tube is all made of the setting of level section, can effectively improve collision energy-absorbing effect, while also ensuring the stability of energy-absorbing.
3. various deformation combines, collision energy-absorbing effect is effectively improved.
Energy-absorbing box device involved in the utility model, collision initial stage are bent and deformed energy-absorbing, when the small round tube phase of level
Mutually by collapse-fold energy-absorbing when contact, while the expansion energy-absorbing of connecting inner filling aluminum foam, a variety of energy-absorbing modes combine again.
4. Multi-angle impact adaptability is high
The inside of energy-absorption box involved in the utility model is filled with the aluminum foam of change of gradient, close to the one of collision prevention girders
Section foam density is small, and one section far from collision prevention girders, foam density is big, and the filling of such gradient foam has been effective against angled
Mechanics unstable phenomenon under impact generates, and can effectively improve the whole stability under the oblique impact of multi-angle of structure, more
The utilization rate for playing material well is greatly lowered energy absorbing efficiency due to avoid because of endergonic structure under oblique impact unstability and jeopardizes automobile
The life and its property safety of occupant.

Specific embodiment
Explanation is further described combined with specific embodiments below.It should be noted that: following embodiment is only to illustrate this
Utility model not limits technical solution described in the utility model, all do not depart from the technical solution and its improvement of this range
It should all include in the scope of the claims of the utility model.
The utility model proposes a kind of novel automobile energy-absorbing box device, as shown in Figure 1.Main includes double-deck six sides
Shape thin-wall construction 1, internal special interstitital texture 2 and gradient aluminum foam 3 are constituted.Upper end can be touched by being fixedly welded on automotive front end
Crossbeam is hit, lower end can be first welded on ring flange, then be bolted on automobile longitudinal girder.
Fig. 2 is the three-dimensional figure of the special internal interstitital texture of the double-deck hexagon thin-wall construction.The bilayer hexagon thin-walled knot
The interstitital texture of structure is made of five layers of hexagonal plate and 24 round tubes, can be by being welded and fixed between round tube and hexagonal plate.
One layer and five layers of hexagonal plates inside filling self similarity level hexagonal honeycomb structure, i.e., connect at the angle of traditional hexagonal honeycomb
Meeting place, addition hexagonal cross-section is constituted again, and filled honeycomb section is as shown in Figure 3.Intermediate three layers of hexagonal plate fill tradition
Hexagonal honeycomb, as shown in Figure 4.24 small round tubes are also configured as level Multi cell structure, pass through the friendship in internal floor and inner ring
Meeting place, addition circular configuration is constituted again, and section form is shown in Fig. 5.
Special arrangement is that every layer of small round tube of adjacent level is staggered, such as six round tubes of the first floor are distributed in six
The corner junction of side tee section, two layers of six small round tube are distributed in the midpoint of hexagonal cross-section, three layers of six level roundlet
Pipe is arranged at the angle unit of hexagonal cross-section again, and special arrangement in this way forms staggered form.Start due to
Round tube is staggered and not in contact in addition three layers of hexagonal plate of internal layer are due to filling traditional hexagonal cross-section honeycomb relative to upper
The intensity of lower two layers of hexagonal plate is low, therefore at collision initial stage, energy-absorption box becomes mainly by the bending of three hexagonal plates of internal layer
Shape energy-absorbing.When collision persistently proceeds to the contact of level round tube, energy-absorbing box structure mainly begins through compression level roundlet pipe and comes
Absorb collision energy.Its ideal collision process schematic diagram is as shown in Figure 6.Cleverly special setting in this way, so that energy-absorbing box structure is touched
Initial stage is hit by bending deformation energy-absorbing, to reduce initial spike power, the middle and later periods by the collapse-fold of level pipe deform energy-absorbing come
Ensure integral energy-absorbing amount, energy absorption at this moment significantly improves, to ensure that the lasting high efficiency energy-absorbing of energy-absorption box, so as to the greatest extent
The transmitting of the reduction energy of great dynamics, protects occupant safety.In addition the aluminum foam material that the internal density filled changes in gradient
(shown in Fig. 7) can ensure the Multi-angle impact adaptability of energy absorption device, guarantee structural stability.
The above is only the preferred embodiments of the utility model, but the scope of the utility model is without being limited thereto, the skill of this field
Art personnel are easily envisaged that variation disclosed in the utility model or technical scope.Alternative solution is intended to cover practical at this
In novel range.Therefore, the protection scope of the utility model should be determined by the scope of the claims.
