The invention relates to the technical field of automobile parts, in particular to a front longitudinal beam avoiding and reinforcing combined structure. The structure comprises a front longitudinal beam body formed by extruding aluminum alloy, the front longitudinal beam body is of a hollow cavity structure with a plurality of longitudinal beam cavities distributed longitudinally, an avoidance assembly for avoiding a transmission shaft is arranged on the front longitudinal beam body, a receding area is dug in the front longitudinal beam body, a receding assembly is fixedly installed at the receding area in a welded mode and is an extrusion profile mechanism, a crushing characteristic rib is arranged at the front end of the top of the front longitudinal beam body, side face reinforcing ribs are arranged on the two sides of the front longitudinal beam body, and the side face reinforcing ribs are vertically arranged. The crushing characteristic rib and the side reinforcing ribs are beneficial for improving the strength of the front longitudinal beam body and the buffering capacity for resisting collision, so that the collision impact energy transmitted from the front end to a vehicle cab is reduced, and the safety of a driver is protected.

    本发明涉及汽车零部件技术领域,具体是涉及一种前纵梁避让加强组合结构,包括铝合金挤压成型的前纵梁本体,前纵梁本体为具有多个纵向分布的纵梁型腔的中空型腔结构,前纵梁本体上设置有避让传动轴的避让组件,前纵梁本体上挖空有避让区,避让区处通过焊接固定安装避让组件,避让组件为挤出型材机构,前纵梁本体的顶部前端设置有压溃特征筋,前纵梁本体的两侧设置有侧面加强筋,侧面加强筋竖直设置,通过压溃特征筋和侧面加强筋有利于提高前纵梁本体的强度与抵抗碰撞的缓冲能力,进而降低从前端传递到车辆驾驶舱的碰撞冲击能量,保护乘车驾驶员安全。
