The invention provides an automobile rear anti-collision beam. The automobile rear anti-collision beam comprises a beam body. The two energy absorption devices are installed at the two ends of the beam body in the first direction respectively, each energy absorption device is of a hollow structure and extends in the second direction, each energy absorption device is provided with an energy absorption induction groove extending in the first direction, and each energy absorption induction groove is a recess formed by inwards protruding and bending the corresponding energy absorption device; wherein the first direction is crossed with the second direction. By means of the arrangement, when the rear portion of the automobile is collided in the second direction, the bent and sunken energy absorption induction groove can guide the energy absorption device to be folded and deformed in the second direction, and therefore collision energy from a rear automobile is effectively absorbed.

    本申请提供一种汽车后防撞横梁,包括:横梁本体;两个吸能装置,分别安装于所述横梁本体在第一方向上的两端,所述吸能装置为中空结构且沿第二方向延伸,所述吸能装置设置有沿所述第一方向延伸的吸能诱导凹槽,所述吸能诱导凹槽为所述吸能装置向内凸出弯折形成的凹陷;其中,所述第一方向与所述第二方向交叉。通过该设置,在汽车后方沿第二方向遭受碰撞时,弯折凹陷的吸能诱导凹槽能够引导吸能装置沿第二方向产生折叠变形,从而有效地吸收来自后车的碰撞能量。
