With the lightweight of automobile, automobile buffer beam gradually adopts plastic material, and collision prevention girders are by outside plate, cushion and horizontal stroke
Beam forms, and outside plate and cushion are adopted made of plastic, and crossbeam use U-type groove plate, and it has the cold rolling that thickness is 1.5mm or so
Sheet stamping is formed, and outside plate and cushion are attached on crossbeam, together with crossbeam is bolted with longitudinal beam.Work as generation
During collision accident, the plastic buffer layer of automobile buffer beam possesses certain energy-absorbing buffering ability, but energy-absorbing buffering effect is limited,
It equally can not effectively protect automobile and personal security.
Further, also have some automobile buffer beams to employ hollow double-layer steel plate structure, or in hollow double-layer plate
Between potting resin, although this collision prevention girders also possess certain energy-absorbing buffering ability, energy-absorbing buffering effect is equally limited,
Automobile and personal security can not effectively be protected.
Therefore, Patent No. ZL201620121549.0 Chinese patent discloses a kind of foamed aluminium automobile buffer beam, should
Automobile buffer beam is while automotive light weight technology is ensured and energy-absorbing buffering ability is strong, once crash, the automobile collision preventing
Beam can fully absorb impact energy, farthest ensure automobile and personal security.
But when the automobile buffer beam is using single foamed aluminium material manufacture, find in powerful impact effect
Under, the easily chipping phenomenon of single foamed aluminium material, while come off with fragment, once duplicate shock, it is impossible to
The performance energy-absorbing buffering effect remained valid, causes automobile and personal security can not obtain continuing to protect when duplicating shock
Card.
Utility model content
The problem of existing for prior art, the utility model, which provides a kind of foamed aluminium/fiber weaving cloth compound vehicle, to be prevented
Beam is hit, under powerful impact effect, foamed aluminium is not likely to produce fragmentation, even if there is fragmentation, fragment also will not fall off, and can have
Effect is retained in the original location by fiber weaving cloth, even if duplicating shock, remains to the performance energy-absorbing buffering effect remained valid, makes automobile
And personal security continues to be guaranteed.
To achieve these goals, the utility model adopts the following technical scheme that：A kind of foamed aluminium/fiber weaving cloth is compound
Automobile buffer beam, including backboard and energy-absorbing buffering layer, the energy-absorbing buffering layer are fixedly bonded to the preceding surface of backboard, backboard and vehicle frame
Longeron is riveted or welded together, and is characterized in：The energy-absorbing buffering layer is combined by foamed aluminium and fiber weaving cloth, foamed aluminium
Using single layer structure or sandwich construction；When the foamed aluminium uses single layer structure, the fiber weaving cloth is coated on single layer foam aluminium
Outer surface；When the foamed aluminium uses sandwich construction, fiber weaving cloth interlayer is provided between foamed aluminium layer, and in outermost layer foam
The outer surface of aluminium is coated with fiber weaving cloth.
The foamed aluminium is connected with fiber weaving cloth using bonding way.
The thickness range of the energy-absorbing buffering layer is 50mm~200mm, the width range on vertical direction for 100mm~
300mm。
The backboard is made up of steel plate, aluminium sheet or carbon fiber board, and the thickness range of backboard is 3mm~5mm.
The fiber weaving cloth is weaved cotton cloth using fiberglass woven cloth, PE fiber weaving cloths, carbon-fiber cloth or aramid fiber.
The beneficial effects of the utility model：
The utility model compared with prior art, first by foamed aluminium and fiber weaving cloth Application of composite in automobile buffer beam
In, the original energy-absorbing buffering ability of foamed aluminium is not only remained, after foamed aluminium and fiber weaving cloth composite joint, is also significantly improved
The anti-cross direction tear strength of collision prevention girders, even if collision prevention girders, by strong shock, foamed aluminium is not easy to produce fragmentation, even if bubble
There is fragmentation in foam aluminium, and the fragment of foamed aluminium also will not fall off, and can effectively be retained in the original location by fiber weaving cloth, be hit even if duplicating
Hit, the performance energy-absorbing buffering effect remained valid is remained to, so that automobile and personal security continue to be guaranteed.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of foamed aluminium/fiber weaving cloth compound vehicle collision prevention girders, including backboard 1 and energy-absorbing buffering
Layer, the energy-absorbing buffering layer are fixedly bonded to 1 preceding surface of backboard, and backboard 1 is riveted or welded together with longitudinal beam 2, described
Energy-absorbing buffering layer is combined by foamed aluminium 3 and fiber weaving cloth 4, and foamed aluminium 3 uses single layer structure or sandwich construction；The foam
When aluminium 3 is using single layer structure, the fiber weaving cloth 4 is coated on the outer surface of single layer foam aluminium；The foamed aluminium 3 uses multilayer knot
During structure, the interlayer of fiber weaving cloth 4 is provided with the interlayer of foamed aluminium 3, and fiber weaving cloth 4 is coated with the outer surface of outermost layer foamed aluminium 3.
The foamed aluminium 3 is connected with fiber weaving cloth 4 using bonding way.
The thickness range of the energy-absorbing buffering layer is 50mm~200mm, the width range on vertical direction for 100mm~
300mm。
The backboard 1 is made up of steel plate, aluminium sheet or carbon fiber board, and the thickness range of backboard 1 is 3mm~5mm.
The fiber weaving cloth 4 is weaved cotton cloth using fiberglass woven cloth, PE fiber weaving cloths, carbon-fiber cloth or aramid fiber.
The protection philosophy of foamed aluminium of the present utility model/fiber weaving cloth compound vehicle collision prevention girders is as follows：
Because the energy absorption of foamed aluminium is up to 10000KJ/m3~20000KJ/m3, its compression intensity up to 5MPa~
10MPa, and be bonded in silicone adhesive on backboard 1.By conduct oneself with dignity be 2000kg automobiles exemplified by, collision speed per hour is 50km/h, this practicality
New automobile buffer beam front energy absorption will be greater than automobile frontal impact kinetic energy, therefore can fully absorb punching by collision prevention girders
Hit energy.Because foamed aluminium deformation intensity is up to 5MPa~10MPa, it is far below the intensity of longitudinal beam 2, so as to ensure foamed aluminium
Deform and longitudinal beam 2 is indeformable, therefore could effectively protect automobile and personal security.Above-mentioned collision prevention girders are applied to vehicle frame
The less high automobile of the intensity of longeron 2.
Because the tensile strength of fiber weaving cloth 4 is higher than 1000MPa, when foamed aluminium 3 is together with the compound sticking of fiber weaving cloth 4
Afterwards, the anti-cross direction tear strength of collision prevention girders can be made to be higher than 300MPa, even if by strong shock, foamed aluminium 3 is not easy to produce
Fragmentation, even if fragmentation occurs in foamed aluminium 3, the fragment of foamed aluminium 3 also will not fall off, and effectively can be retained in the original location by fiber weaving cloth 4,
Even if duplicating shock, the performance energy-absorbing buffering effect remained valid is remained to, so that automobile and personal security continue to obtain
Ensure.
Scheme in embodiment simultaneously is not used to limit scope of patent protection of the present utility model, all without departing from the utility model
Carried out by equivalence enforcement or change, be both contained in the scope of the claims of this case.
