Abstract
The utility model relates to a front anti-collision beam energy absorption box for a car, which is mounted on an anti-collision beam at the front part of the car. The front anti-collision beam energy absorption box comprises a cylindrical energy absorption box body, wherein the energy absorption box body is of a round table or a frustum with small section at the front end and large section at the back end, and a plurality of energy absorption grooves which are arranged in parallel are arranged on the two side surfaces of the energy absorption box body. The front anti-collision beam energy absorption box disclosed by the utility model has good anti-side tipping capability during the collision process of the car and can effectively absorb collision energy and ensure the safety in traveling, and the front anti-collision beam energy absorption box has the advantages of simple integral structure, good manufacturability, low cost and high performance-price ratio.
Description
Technical field
The utility model belongs to car parts technical field, is specifically related to a kind ofly be installed in car on the anterior collision prevention girders of car with front anti-collision beam energy-absorbing box.
Background technology
For improving the safety of car front shock, car generally all is equipped with front anti-collision beam, and its main body is made up of crashproof crossbeam, energy-absorbing box and adapter plate.When vehicle generation high-speed crash, significantly axially crumple distortion can take place in the energy-absorbing box, relies on distortion absorbing impact kinetic energy, reduces the speed of a motor vehicle, thereby reaches the purpose of improving safety.
Existing energy-absorbing box is prone to the inclination phenomenon in the high-speed crash process, the inclination of energy-absorbing box has destroyed normal energy-absorbing function, has influenced vehicle safety.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned defective, provides a kind of and has the energy-absorbing box inclination that prevents in the collision process, car simple in structure with front anti-collision beam energy-absorbing box.
To achieve these goals, the utility model design-calculated car comprises tubular energy-absorbing box body with front anti-collision beam energy-absorbing box, and said energy-absorbing box body is big truncated cone-shaped or the taper type of front end section ratio little back end section.
The two sides of above-mentioned energy-absorbing box body are equipped with a plurality of energy-absorbing grooves that are arranged in parallel.
Above-mentioned energy-absorbing box body is welded by upper plate and the lower plate fastening that cross-sectional plane is U-shaped, is faying surface between said two adjacent energy-absorbing grooves, and said upper plate and lower plate are weldingly connected through faying surface.
The upper surface of above-mentioned upper plate is provided with knock hole.
The steel design part make-up that it is U-shaped that the utility model the adopts two cross-sectional planes energy-absorbing box body that is welded, its front end and crashproof crossbeam are weldingly connected, and rear end and adapter plate are weldingly connected; The front end cross-sectional plane is littler than rear end cross-sectional plane, and integral body is truncated cone-shaped or taper type, energy-absorbing box body both sides alternative arrangement energy-absorbing groove; Constitute the crumple muscle of alternative arrangement, in the car collision process, possess well anti-roll capability; Effectively the absorbing impact energy has guaranteed traveling security, and integral structure is simple; Anufacturability is good, and cost is low, and cost performance is high.
