Vehicle door anti-collision rod and vehicle door using the same

Abstract

The invention relates to an automobile side door beam and an automobile door using the beam. Two parallel side door beams with higher front and lower back are adopted on automobile front doors, while single side door beams with lower front and higher back are adopted on back doors. Arranged in the way, on one hand, the arrangement is conducive to frontal collision force transfer: the side door beams can share the transfer force of a reinforcing plate at a BELT-LINE, effectively transfer force from frontal collision of the automobile body to the rear part of the automobile body, so that rigidity of the passenger compartment of the automobile body is strengthened and security of the passenger compartment is consequently improved; on the other hand, in case of a lateral collision, the back of the front side door beams is lower, while the front of the back side door beams is lower and is at the lower end of a B column where the B column features large section and high strength, thus improving capacity to resist lateral collision. A front row seat R is arranged between the two parallel side door beams of the front doors, so that the side door beams can effectively prevent the lateral invasion to lateral doors and protect body parts of passengers below the crotch. The front door parallel side door beams and back door single side door beams are arranged in the middle of the gibbous collision surface of a collision device, so that the side door beams can achieve rapid effect in case of lateral collision and prevent invasion of lateral doors, thus giving the passengers the largest living space.

Description

technical field [0001] The invention relates to an automobile door anti-collision bar and an automobile door using the anti-collision bar, in particular to an automobile door anti-collision bar for the side door of M1 type automobiles and an automobile door using the anti-collision bar. Background technique [0002] With the development of technology, consumers have higher and higher requirements for the collision safety performance of the vehicle. It is mainly reflected in the increasingly stringent requirements of insurance companies and relevant institutions for new car safety assessments and national and regional laws and regulations. For side impacts, it is already difficult to meet these requirements by using a single anti-collision bar or anti-collision plate that is generally cold-formed, that is, it is difficult to meet the required collision safety requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
