Integrated impact-resistant front anti-collision beam of automobile

Abstract

The invention discloses an integrated impact-resistant front anti-collision beam of an automobile. The anti-collision beam comprises an arched front beam, buffering energy absorption boxes, inner enhanced anti-collision columns, thickened L-shaped connecting plates, a small folding clamping plate and an upper connecting plate. Arc-shaped thickening curved surfaces are arranged above and below theinner side of the arched front beam. The bottoms of the buffering energy absorption boxes are welded and fixed on the left and right inner sides of the arched front beam. The inner reinforced anti-collision columns are fixed to the bottoms of the inner sides of the buffering energy absorption boxes, and the bottoms of the inner reinforced anti-collision columns and the inner side of the arched front beam are connected into a whole. The thickened L-shaped connecting plates and the upper tops of the buffering energy absorption boxes are welded into a whole. The upper connecting plate and the small folding clamping plate are welded and fixed to the outer sides of the upper side face and the lower side face of the arched front beam. The anti-collision beam is an integrated connecting mechanism, multiple fixed connections by bolts are omitted, it is guaranteed that the inner side of the arch-shaped front beam only sinks inwards and cannot be broken during collision, and it is guaranteed that the overall anti-collision performance is excellent.

Description

technical field [0001] The invention relates to the field of one-piece front anti-collision beams, in particular to an automobile one-piece impact-resistant front anti-collision beam, which belongs to the field of vehicle front beam structural components. Background technique [0002] The front beam of the car tightly connects the relevant structural components on the left and right sides of the car. It is the main force-bearing mechanism component of the front end of the car body in the chassis frame of the car. The inner side of the beam is usually equipped with an air conditioning system, the outer side is equipped with an air intake grille, and the bottom two sides are equipped with mud water guards. When the front end of the car is hit, the front beam of the car is an important force-bearing mechanism, especially the front beam of a family car is the main protection structure for frontal collision. However, there are the following problems in the common front beam stru...

AI Technical Summary

Problems solved by technology

However, there are the following problems in the common front beam structural components: 1. The overall design is unreasonable. During the vehicle crash test, the inner side of the arched front beam is easy to break. Mounting holes are processed on the front of the arched front beam, resulting in a significant drop in the impact resistance of the arched front beam; 2. The energy-absorbing box in the structural components of the front beam is fixedly connected by bolts, and the energy-absorbing box and the chassis of the vehicle The connection plate between the two parts is connected by bolts. When the front beam of the vehicle in this area collides head-on, the bolts are easy to break due to the shear force, so that the buffer energy-absorbing box and the connection plate cannot effectively and reasonably absorb the impact force. 3. The design of the buffer energy-absorbing box in the front beam structural components is unreasonable, and the design of the overall connection area between the buffer energy-absorbing box and the arched front beam is unreasonable, which makes the buffer energy-absorbing The deformation recovery performance of the box is poor, and the ability to offset the impact is poor
