Automobile front anti-collision beam structure and application thereof to automobiles

Abstract

Disclosed are an automobile front anti-collision beam structure and application thereof to automobiles. The automobile front anti-collision beam structure is composed of a main beam, an inner plate and an energy absorbing device, wherein the inner plate is fixedly connected to the main beam; the energy absorbing device is fixedly connected to the inner plate and at least composed of a bottom plate, a first conical tube, a second conical tube and a third conical tube; the bottom ends of the first conical tube, the second conical tube and the third conical tube are fixedly mounted onto the bottom plate, and the first conical tube, the second conical tube and the third conical tube are gradually nested from inside to outside; the heights of the three conical tubes are gradually reduced from inside to outside, the diameters of the bottom ends of the three conical tubes are gradually increased from inside to outside, the thicknesses of the three conical tubes are gradually increased from inside to outside, and the tapers of the three conical tubes are gradually increased from inside to outside. According to the automobile front anti-collision beam, when collision deformation occurs, crumple of a single stage gradually develops into simultaneous crumple of two stages and then into simultaneous crumple of three stages, plastic deformation can be gradually increased, a regular and stable deformation mode and significant buffer effects can be achieved, and energy absorption can be gradually increased. Therefore, the automobile front anti-collision beam can enhance structural stability and crashworthiness and meanwhile improve the collision angle adaptability.

Description

technical field [0001] The invention relates to the structure of the front anti-collision beam of the automobile and the application on the automobile. Background technique [0002] With the improvement of people's living standards, in order to meet the convenience of daily travel, the number of cars is increasing day by day. At the same time, the number of automobile collision accidents is also rising sharply, and the safety performance and maintenance cost of automobiles have attracted more and more people's attention and the attention of automobile engineers. The front anti-collision beam and the energy-absorbing box of the car are the primary devices to reduce the impact load of the vehicle collision and absorb the collision energy. The hazards of accidents play an extremely important role in protecting the lives and property of passengers. Therefore, it is very important for automobiles to be equipped with front anti-collision beams and energy-absorbing devices with h...

AI Technical Summary

Problems solved by technology

However, many anti-collision beams currently on the market have insufficient crashworthiness. The structure of the energy-absorbing box is simple and the energy-absorbing effect is poor. impact energy, causing the longitudinal beam and the passenger compartment to bear a large amount of impact energy, posing a threat to the safety of the occupants, and easily causing damage to the main body structure and increasing maintenance costs
