Abstract

The invention discloses an automobile anti-collision device. The anti-collision device comprises an automobile front bumper composed of an external plate, a buffer material and a cross beam; and a plate-shaped crumple device is positioned between the external plate and the buffer material, comprises a plurality of layers of crumple plates, and is connected with the buffer material through a buckle. According to the technical scheme, the collision crumple device is arranged in the automobile front bumper and absorbs most energy through crumple deformation during collision, so that safety of passengers and pedestrians is improved greatly. Simultaneously, the automobile anti-collision device has the advantages of obvious safety effect, low production cost, long service life and the like.

Description

Anti-collision device for automobile
Technical field
The invention belongs to automobile body accessories manufacturing technology field, specifically, belong to anti-collision device for automobile.
Background technology
At present, in automobile body accessories anticollision device field, Federal bumper plays an important role as the requisite important safety parts of vehicle.Federal bumper is the safety device that absorbs the foreign impacts power that relaxes, protection vehicle body front and rear part.Very early, the car front/rear collision bumper is take metallic material as main, is that steel plate stamping more than 3 millimeters is pressed into the U-lag steel with thickness, surface treatment chromium plating, with chassis side rail riveted joint or weld together, with vehicle body one section larger gap is arranged, seem parts that add up.
Along with the development of auto-industry, Federal bumper has also moved towards on the road of innovation as a kind of important safety device.The car front/rear collision bumper of today also will be pursued harmony and unification with the car body moulding, the lightweight of pursuit itself except keeping original defencive function.In order to reach this purpose, the front/rear collision bumper of car has adopted plastics at present, and people are called plastic bumper.
In the prior art, plastic bumper is comprised of outside plate, padded coaming and crossbeam three parts.Wherein outside plate and padded coaming are made of plastic, and the crossbeam cold-rolling thin plate is stamped to form U-lag; Outside plate and padded coaming are attached on the crossbeam, and crossbeam is connected with the chassis side rail screw, can disassemble at any time.
Owing to lack the anti-collision energy absorption device in the bumper/spoiler of the prior art, have following many technical matterss:
1, owing to lack the anti-collision energy absorption device in the prior art, when collision happens, most of Impact energy is passed to chaufeur and passenger by car body, cause casualties.
2, owing to lack the anti-collision energy absorption device in the prior art, when vehicle and pedestrian bump, lack pedestrian protection, make easily the pedestrian seriously injured.
Summary of the invention
Technical matters to be solved by this invention is, owing to lack the anti-collision energy absorption device in the prior art, when collision happens, most of Impact energy passed to chaufeur and passenger by car body, causes casualties; When vehicle and pedestrian bump, lack pedestrian protection, make easily the technical matterss such as the pedestrian is serious injured, and anti-collision device for automobile is provided.
Technical conceive of the present invention is; lack anti-collision energy absorption device and pedestrian protection in the above-mentioned prior art for solving; when bumping; the technical matters such as cause casualties; technical scheme of the present invention is the bump buckling device to be set, the crumple distortion during by bump in the motor insurance front bumper; absorb most of ability, so that passenger and pedestrains safety are greatly enhanced.
Technical scheme provided by the present invention is, anti-collision device for automobile comprises automobile front beam, and described front bumper is comprised of outside plate, padded coaming and crossbeam three parts, is provided with tabular buckling device between described outside plate and padded coaming.
Described tabular buckling device comprises that some layers of crumple plate consist of, and described buckling device is connected with described padded coaming by buckle.
The longitudinal cross-section of described outside plate is " U " shape structure, and described buckling device is arranged on the top of described " U " shape structure.
Described tabular buckling device integral body is " C " shape.
The impact of crumple plate carrying is progressively strengthened from the outer to the inner in the described buckling device.
Be provided with cellular structure in the described crumple plate, this cellular structure is by ruptural deformation, absorbing impact energy.
Adopt technical scheme provided by the present invention, can effectively solve owing to lack the anti-collision energy absorption device in the prior art, when collision happens, most of Impact energy is passed to chaufeur and passenger by car body, cause casualties; When vehicle and pedestrian bump; lack pedestrian protection; make easily the technical matterss such as the pedestrian is serious injured; the technical scheme of invention is; the bump buckling device is set in the motor insurance front bumper; crumple distortion during by bump absorbs most of ability, so that passenger and pedestrains safety are greatly enhanced.Simultaneously, it is remarkable that the present invention also has safe effect, low cost of manufacture, the characteristics such as long service life.
Description of drawings
By reference to the accompanying drawings, the present invention is further illustrated:
Fig. 1 is bumper scheme drawing of the present invention;
Wherein, 1 is bumper/spoiler.
The specific embodiment
As shown in Figure 1, technical scheme provided by the present invention is, anti-collision device for automobile comprises automobile front beam 1, and described front bumper 1 is comprised of outside plate, padded coaming and crossbeam three parts, is provided with tabular buckling device between described outside plate and padded coaming.
Described tabular buckling device comprises that some layers of crumple plate consist of, and described buckling device is connected with described padded coaming by buckle.
The longitudinal cross-section of described outside plate is " U " shape structure, and described buckling device is arranged on the top of described " U " shape structure.
Described tabular buckling device integral body is " C " shape.
The impact of crumple plate carrying is progressively strengthened from the outer to the inner in the described buckling device.
Be provided with cellular structure in the described crumple plate, this cellular structure is by ruptural deformation, absorbing impact energy.
Described outside plate can be selected to be made by the plastics that poly-carbon ester is, infilters alloying component, adopts the injection molding method of alloy, the bumper/spoiler 1 that processes not only has high-intensity rigidity, also have the advantage that can weld, and coating performance is good, the consumption on car is more and more.
The present invention can play buffer action when automobile crashes on safety, car body before and after the protection; From the appearance, can be very natural be combined in one with car body, completely be integral, have well ornamentally, become the vitals of decorating the car external form.
