High impact force resistance gas-bag armor

Abstract

The invention relates to a high impact force resistance gas-bag armor, in particular to a high impact force resistance gas-bag armor (or named as a novel bumper) used on an electric automobile. The high impact force resistance gas-bag armor is composed of high resistance foamed plastics, elastoplastics, a charging connector, a high pressure gas and a bumper beam. The invention is characterized in that the higher-thickness high resistance foamed plastics on the outer layer and the elastomer plastics on the inner layer encloses inwards to form a cavity, the gas-bag armor is also provided with the charging connector, the high pressure gas is filled into the cavity through the charging connector and used for absorbing impact energy, and the gas-bag armor is connected with the automobile body through the bumper beam to form an integral body for safety protection. The fuel automobile engine needs a gas inlet fence, but the pure electric automobile does not need the gas inlet fence, thereby leaving space for the installation of the gas-bag armor; therefore, the gas-bag armor is more suitable to be installed on a pure electric automobile. The invention uses the high resistance foamed plastics to enhance the strength of the gas bag, and the impact wave propagated by the high pressure gas in the gas bag can be effectively weakened, thereby satisfying the strength of the impact resistance and achieving the good effects of shock absorption and shock weakening.

Description

technical field [0001] The invention relates to a high-impact airbag armor, in particular to an anti-high-impact airbag armor (or called a new bumper) for electric vehicles. Background technique [0002] At present, most of the bumpers of cars are made of plastic, and the structure of the bumper is made of plastic with sandwich foam structure between the face plastic and the bumper beam, which is used to absorb impact energy, so as to meet the technical standards of aesthetics and safety regulations. The airbag technology installed in the car can effectively protect the drivers and passengers and reduce the casualty rate of accidents. [0003] The impact speed of a woodpecker pecking a tree is 2080 km / h, and when the woodpecker's head bounces off the tree, the impact energy to decelerate it is surprisingly large - about 1000 gravitational constants. You know, if a car hits a brick wall at a speed of 56 kilometers per hour, its force is only 10 gravitational constants. Stra...

Problems solved by technology

[0005] The design and safety performance of traditional bumpers are not enough to compare with the shock absorption performance of woodpeckers and swordfish. The reason is that the fuel engine needs to be equipped with a heat dissipation fence. Therefore, the installation space of the bumper is relatively small, and it is also limited by aesthetic factors. , while pure electric vehicles are powered by batteries, no need to reserve heat dissipation fences, which obviously creates more space for the installation of new bumpers and meets the conditions of aesthetics

[0006] The airbag has strong deformation and shock absorption performance, but its impact resistance strength is weak. The high resistance foam plastic with porous structure has strong impact resistance strength, but the deformation space is small, that is, the shock absorption performance is relatively weak. If the outer layer is made of high-thickness high-resistance foam plastics and the inner layer of elastomer plastic is closed inwardly to form a cavity, and an inflation nozzle is provided, high-pressure gas is filled into the cavity through the nozzle to absorb impact energy
