The invention provides a collision-resistant front bumper anti-collision cross beam comprising a cross beam shell and multiple layers of energy absorption materials. The multiple layers of energy absorption materials are used for absorbing kinetic energy during collision and fill all cabins inside the cross beam shell, the filling densities of the multiple layers of energy absorption materials aresequentially increased from small to large in the filling direction from the inner ring to the outer ring, five small holes are formed in the middle positions of the two side edges of the cross beamshell, and the five small holes are evenly distributed in the axial direction of the cross beam shell. According to the collision-resistant front bumper anti-collision cross beam, collision energy absorption can be improved during collision, the collision force is dispersed, so that the safety of passengers is protected to the greatest extent; meanwhile, the weight can be remarkably reduced by filling the light energy absorption materials, and the fuel economy can be improved.

    本发明提供了一种耐撞性前保险杠防撞横梁,包括:横梁外壳;多层吸能材料,用于在碰撞时吸收动能,填充在横梁外壳的内部各舱中,其中,多层吸能材料按照从内圈到外圈的填充方向,填充密度依次从小变大,横梁外壳的两侧边的居中位置均设有五个小孔,五个小孔沿着横梁外壳轴向均匀分布。本发明的耐撞性前保险杠防撞横梁能够在发生碰撞时提高碰撞吸能,分散了碰撞力,从而最大程度地保护乘客的安全,同时通过填充轻质的吸能材料能够显著地降低重量,有助于提高燃油经济性。
