The invention discloses a pedestrian protection cross beam welding assembly, which comprises two supporting side plate, wherein the two supporting side plates are installed on the two sides of a vehicle body respectively; an anti-collision cross beam is welded between the two supporting side plates; the anti-collision cross beam is located in front of a cooling fin of an automobile water tank; through holes are formed in the ends, which are away from the automobile water tank, of the supporting side plates in a penetrating mode; energy absorption beams are slidably installed in the two throughholes and used for being deformed by collision to absorb energy; an elastic buffer rod is installed on the front side surface of the anti-collision cross beam; and the telescopic end of the elastic buffer rod is away from the anti-collision cross beam and connected with the energy absorption beams. The pedestrian protection cross beam welding assembly has the beneficial effects that the double buffering effect is achieved through deformation of the energy absorption beams and buffering and energy absorption of the elastic buffer rod, the buffering effect is good, and the anti-collision beam can be prevented from hurting legs of pedestrians; and meanwhile, the anti-collision cross beam and the supporting side plates are used for absorbing energy, so that the water tank and the engine are protected, and the protection effect is good.
本发明公开了一种行人保护横梁焊接总成,包括支撑侧板,所述支撑侧板共有两块且分别安装在车身两侧,两块所述支撑侧板之间焊接有防撞横梁,所述防撞横梁位于汽车水箱散热片的前方,所述支撑侧板远离汽车水箱的端部贯穿设置有通孔,两个所述通孔内部滑动安装有吸能梁,用于碰撞发生形变进行吸能,所述防撞横梁前侧面安装有弹性缓冲杆,所述弹性缓冲杆的伸缩端远离所述防撞横梁且与所述吸能梁相连接。有益效果在于:通过吸能梁的形变和弹性缓冲杆的缓冲吸能,起到双重缓冲效果,缓冲效果好,能够防止防撞横梁对行人腿部造成伤害;同时利用防撞横梁和支撑侧板进行吸能,从而对水箱和发动机进行保护,保护效果好。
