Cross car front door anti-collision bar

Abstract

The invention discloses a crossed automobile front door bumper bar. The scheme is that the crossed automobile front door bumper bar comprises bumper bars and a connecting block, wherein two through holes are formed in the connecting block; the two through holes are crossed in an X shape; four bumper bars are arranged; the four bumper bars extend into the through holes in an X shape; parts, extending into the through holes, of the four bumper bars are one parts of four horizontal equally-divided parts of a cylinder; and parts, positioned outside the through holes, of the bumper bars are of arc shapes. The invention aims at providing the crossed automobile front door bumper bar so that the protective strengths of the bumper bars are the sum of the strength of the connecting block and the strengths of the combined bumper bars.

Description

technical field [0001] The invention relates to a cross type automobile front door anti-collision bar. Background technique [0002] With the popularization of automobiles, the safety of automobiles is increasingly concerned. Automobile door anti-collision bars are designed and developed to strengthen the strength and rigidity of automobile doors, as well as the safety performance of automobile collisions and the anti-tilting ability of automobile doors when they are collided. At present, the car door anti-collision bar has the following problems: (1) the current rear door adopts a high-strength steel plate structure. However, due to the large cross-sectional area of ​​the steel plate, the cost of mold development and the weight of the door are increased. (2) When the front and rear doors adopt a single anti-collision bar arrangement, the section of the anti-collision bar is small, and the ability to resist collisions is limited. Moreover, the existing car door anti-collis...

AI Technical Summary

Problems solved by technology

At present, the car door anti-collision bar has the following problems: (1) the current rear door adopts a high-strength steel plate structure. Due to the large cross-sectional area of ​​the steel plate, it can effectively absorb the collision force and inflict damage on the passengers when they are hit by the side. However, due to the large cross-sectional area of ​​the steel plate, the cost of mold development and the weight of the door are increased

(2) When the front and rear doors adopt a single anti-collision bar arrangement, the section of the anti-collision bar is small, and the ability to resist collisions is limited

[0004] In the technical solution of the above-mentioned patent document, one end of the four anti-collision bars is respectively connected to the four forks of the four-pronged tube, so that the protective strength of the anti-collision bar depends on the connection strength between the anti-collision bar and the four-pronged tube, and there is no The reinforcement effect when the anti-collision bar itself is combined together
