The invention relates to a high-energy-absorption alloy anti-collision beam structure for an automobile. The structure comprises a split main beam made of high-energy-absorption alloy, the main beam is fixed on a longitudinal beam of an automobile body through an energy absorption box on the back surface and a mounting plate, and the main beam is divided into a middle beam and two side beams on two sides. The middle beam and the side beams are connected in an inserted mode through T-shaped key grooves and fixed through flange plates located on the outer sides, the joints of the side beams andthe middle beam are arranged to be in triangular shapes with outward openings, and containing grooves for installing reinforcing ribs are formed in the upper surface, the lower surface and the outer side face of the main beam. The main beam made of the high-energy-absorption alloy has the main performance characteristics of high ductility and high energy absorption of the alloy, so that the the impact force is self-decomposed to a certain extent, and damage to a vehicle body is reduced; meanwhile, the split main beam composed of the middle beam and the side beams on the two sides can be used for protecting the middle beam by abandoning the side beams to deal with the small and medium-sized side impact, so that the maintenance cost is reduced.
本发明涉及一种汽车用的高吸能合金防撞梁结构,包括分体式设计的高吸能合金制作的主梁,该主梁通过背面的吸能盒以及安装板固定在车体的纵梁上,主梁分为中间梁以及两侧的两个侧边梁,中间梁与侧边梁之间通过T形键槽相插接并通过位于外侧的法兰盘相固定,侧边梁与中间梁的衔接处设置为开口向外的三角形状,在主梁的上表面、下表面以及外侧面均开设有安装加强筋的收容槽。通过高吸能合金制作的主梁,具有该种合金的主要性能特点高延性和高吸能性,从而对冲击力进行一定的自身化解,有利于缩减对车体的伤害,同时由中间梁和两侧侧边梁组成的分体式主梁,能够通过舍弃侧边梁保全中间梁的方式,应对中小力度的侧面冲击,缩小了维修的成本。
