Energy absorption type front lower protective beam device for automobile

Abstract

The invention discloses an energy absorption type front lower protective beam device for an automobile. The energy absorption type front lower protective beam device comprises a metal tubular crossbeam and two supports for connecting a chassis, wherein the metal tubular crossbeam and the supports for connecting the chassis are connected by bolts or welded into a whole through an energy absorption box; a reinforced oblique support beam is arranged between the supports for connecting the chassis and the metal tubular crossbeam; and the energy absorption box is made of a metal plate, and adopts a hollow structure. According to the energy absorption type front lower protective beam device for the automobile disclosed by the invention, the energy absorption box can generate crushing and folding deformation under the action of a collision force to consume a large amount of collision kinetic energy and achieve the purpose of cushioning, so that the safety of the personal automobile and the safety property of the automobile of the opposite side are improved, and the safety of people in the automobiles is guaranteed. Besides, the energy absorption type front lower protective beam device has the characteristics of being light in weight, high in collision compatibility, high in strength and the like.

Description

technical field [0001] The invention relates to the technical field of automobile safety protection, in particular to an energy-absorbing type automobile front lower protective beam device. Background technique [0002] The car's front lower protective beam device is an important part of the car's passive safety protection system to ensure the safety of the car itself and the safety of the other vehicle. Traditional automobile front lower protective beam devices are produced only with carbon steel rectangular tube beams. Due to the poor yield resistance of ordinary carbon steel, in order to meet the requirements of regulations, it is necessary to increase the wall thickness of the material, resulting in the weight of the product , so that the fuel economy of the whole vehicle is poor. At the same time, if the design of the front protective device is too rigid during the head-on collision of a car or a heavy commercial vehicle, the front protective device will not be able to ...

Problems solved by technology

Traditional automobile front lower protective beam devices are produced only with carbon steel rectangular tube beams. Due to the poor yield resistance of ordinary carbon steel, in order to meet the requirements of regulations, it is necessary to increase the wall thickness of the material, resulting in the weight of the product , so that the fuel economy of the whole vehicle is poor. At the same time, if the design of the front protective device is too rigid during the head-on collision of a car or a heavy commercial vehicle, the front protective device will not be able to buffer and absorb energy in the collision. Even if the collision compatibility of the front protective device is not good, the car will still be at a disadvantage
