Anti-collision beam device of automobile

Abstract

The invention discloses an anti-collision beam device of an automobile. The anti-collision beam comprises a rubber arch plate, a main beam, an energy absorption box and a frame fixing plate; the rubber arch plate is installed at the front end of a shell body of the main beam; the main beam is composed of two baffle plate layers and a reinforcing plate layer, two aluminium alloy reinforcing tubes are installed between each baffle plate layer and the reinforcing plate, and the aluminium alloy reinforcing tubes are fixed by four locating bolts at the bottom; four pairs of symmetric reinforcing rib lines are arranged on the corresponding portions of the locating bolts of the reinforcing tubes of connecting plates of the main beam; the energy absorption box is welded with the main beam, the cross section of the energy absorption box is a regular hexagon, and reinforcing ribs are arranged in the energy absorption box; the frame fixing plate is welded with the energy absorption box and provided with locating pothooks. The anti-collision beam is of a bilaterally symmetrical structure. The device solves the problems that a traditional anti-collision beam of the automobile is instable in energy absorption, low in energy absorption efficiency, and poor in multi-angle impacting adaptability to protect life and property safety of passengers in the automobile, through installment of the locating pothooks, the tedious degree is reduced in the installing and locating processes, and the assembly efficiency is improved.

Description

technical field [0001] The invention provides an automobile anti-collision beam device, which belongs to the technical field of automobiles. Background technique [0002] With the rapid development of the automobile industry, people began to pay more and more attention to the driving safety of the car while pursuing the power and economy of the car, and put forward more and more stringent requirements for the driving safety of the car. Therefore, the safety performance It has become one of the important quality indicators of modern cars. The anti-collision beam of a car is a safety device that deforms when the car is subjected to an external collision, absorbs energy, and provides a buffering effect to achieve the purpose of protecting the safety of people in the car. The anti-collision beam is usually installed in front of the front of the car body and hidden in the front bumper. The anti-collision beam can effectively improve the safety performance of the car, so the perf...

AI Technical Summary

Problems solved by technology

However, in the existing technology, the anti-collision beam currently used lacks a more effective reinforcement structure and does not have stable deformation, which makes its own energy absorption effect unsatisfactory, and the installation process often leads to low assembly efficiency due to the long main beam
