Front anti-collision beam of small car

Abstract

The invention relates to a front anti-collision beam of a small car, which is used for solving the joint problem of a cross beam and skin, and comprises the cross beam and energy absorbing boxes symmetrically arranged at the two sides of the cross beam, wherein the cross beam is in a three-section structure, and each section of the cross beam is of an equivalent radius arc; and the two side sections of the cross beam bend inwards at a bending angle of alpha relative to the middle section of the cross beam, and alpha ranges from 3 degrees to 15 degrees. The invention has the following characteristics that: 1. the cross beam adopts the equivalent radius three-section arc structure, and when the radian of the outer surface of the cross beam is inconsistent with the radian of the outer surface of the skin, the angle of the bending angle between arcs can be changed to meet the requirements of the joint design of the outer arc surface of the cross beam and the outer surface of the skin; 2. a water tank support is arranged on the cross beam so as to replace a plurality of stamping parts for installing a water tank, thereby reducing the weight of a car body, saving material cost and simplifying process; 3. a release assembly is installed on a mounting plate at one side of the water tank support, so that the weight of the car body is further reduced, and the shape of the anti-corrosion beam is attractive.

Description

technical field [0001] The invention relates to an automobile component, in particular to a front anti-collision beam suitable for various small automobiles, and belongs to the technical field of automobiles. Background technique [0002] As a means of transportation and means of transportation, automobiles are becoming more and more popular. The safety, comfort and environmental protection of automobiles have become important quality indicators of modern automobiles. The front anti-collision beam of the automobile is an important part to protect the safety of the occupants to the maximum extent in the event of a collision accident, and the rationality of its structural design has become the direction of efforts of various automobile manufacturers. The main components of the front anti-collision beam of various small cars include a beam and an energy-absorbing box, and the beam is a section of equal-radius arc structure. The outer curved surface of the beam should be design...

AI Technical Summary

Problems solved by technology

This installation method can leave energy-absorbing space for the front anti-collision beam without affecting the deformation of the front anti-collision beam, but this method uses a lot of sheet metal parts, which not only increases the weight of the vehicle but also increases the production cost

In addition, the decoupling should be installed on the beam of the front anti-collision beam. The regulations have stri...
