The invention discloses a lower A-pillar reinforcing structure beneficial to front collision performance, which comprises an automobile lower A-pillar inner plate, an automobile lower A-pillar outer plate and a reinforcing plate structure arranged between the automobile lower A-pillar inner plate and the automobile lower A-pillar outer plate, and the reinforcing plate structure comprises a large reinforcing plate and a group of small reinforcing plates, the large reinforcing plate is of an integrated reinforcing plate structure, and the small reinforcing plate is arranged in the large reinforcing plate. The lower A column reinforcing structure beneficial to the front collision performance is reasonable in design, the threshold and the lower A column are in lap joint firmly through the structure, the strength of the A column can be flexibly controlled, and the performance of all working conditions of front collision is obviously improved; and the backward movement amount of the lower A column is reduced, so that structural score penalty in collision and score penalty in dummy scoring are avoided.

    本发明公开了一种有利于前部碰撞性能的下A柱加强结构,包括汽车下A柱内板和汽车下A柱外板以及设置在汽车下A柱内板和汽车下A柱外板之间的加强板结构,所述加强板结构包括大加强板和一组小加强板,所述大加强板为一体式加强板结构,小加强板设在大加强板内。该有利于前部碰撞性能的下A柱加强结构设计合理,此结构使门槛与下A柱搭接牢固,且能灵活控制A柱强度,对前碰各工况性能提升明显;减小下A柱后移量,以避免碰撞中结构罚分及假人评分中的罚分。
