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

Car is with front anti-collision beam energy-absorbing box

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.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:

Car as shown in Figure 1 is with front anti-collision beam energy-absorbing box; Comprise tubular energy-absorbing box body 1; Said energy-absorbing box body 1 is end section behind the front end section ratio little truncated cone-shaped or taper type (tubular energy-absorbing box body 1 is a front end with the end that crashproof crossbeam is weldingly connected, and an end that is weldingly connected with adapter plate is the rear end).

As shown in Figure 2, the two sides of energy-absorbing box body 1 are equipped with a plurality of being arranged in parallel and interlaced energy-absorbing groove 2.Energy-absorbing box body 1 is U-shaped by cross-sectional plane upper plate 1.1 fastens be welded (structure such as Fig. 3 and shown in Figure 4 of upper plate 1.1 and lower plate 1.2) with lower plate 1.2; Between two adjacent energy-absorbing grooves 2 is faying surface 4, and upper plate 1.1 is weldingly connected through faying surface 4 with lower plate 1.2.The upper surface of the upper plate 1.1 of energy-absorbing box body 1 is provided with knock hole 3, when being used to assemble and the framing member location and installation of car.

When the utility model uses; As shown in Figure 5, the front portion of energy-absorbing box body 1 and crashproof cross-beam body 5 are welded to connect, and the rear portion of energy-absorbing box body 1 and crashproof crossbeam adapter plate 6 are welded to connect; Constitute car and use collision prevention girders; Absorbing impact energy in the vehicle collision process the inclination failure phenomenon can not occur simultaneously in deformation process, possess anti-preferably roll capability.
