The invention belongs to the technical field of automobile front longitudinal beams, and relates to a front longitudinal beam and an automobile. The front longitudinal beam comprises a front longitudinal beam body with the cross section shaped like a Chinese character 'mu', wherein the front longitudinal beam body comprises a rectangular frame, a first reinforcing plate and a second reinforcing plate, the rectangular frame comprises an upper transverse plate, an inner longitudinal plate, a lower transverse plate and an outer longitudinal plate which are connected in sequence, the upper transverse plate is located above the lower transverse plate, the inner longitudinal plate is connected between the inner side of the upper transverse plate and the inner side of the lower transverse plate,the outer longitudinal plate is connected between the outer side of the upper transverse plate and the outer side of the lower transverse plate, the first reinforcing plate and the second reinforcingplate are arranged in an inner space of the rectangular frame, the first reinforcing plate is located above the second reinforcing plate, and the first reinforcing plate and the second reinforcing plate are connected between the inner longitudinal plate and the outer longitudinal plate so as to divide the inner space of the rectangular frame into three sub-cavities which are stacked up and down. On the premise of absorbing the same collision energy, the front longitudinal beam can provide a smaller section size and a more stable crushing form.

    本发明属于汽车前纵梁技术领域,涉及一种前纵梁及汽车,该前纵梁包括截面呈“目”字型的前纵梁本体,所述前纵梁本体包括矩形框架、第一加强板及第二加强板,所述矩形框架包括顺次相连的上横板、内纵板、下横板以及外纵板,所述上横板位于下横板的上方,所述内纵板连接在上横板的内侧与下横板的内侧之间,所述外纵板连接在上横板的外侧与下横板的外侧之间,所述第一加强板及第二加强板设置在矩形框架的内部空间中,所述第一加强板位于第二加强板的上方,所述第一加强板及第二加强板连接在内纵板与外纵板之间,以将矩形框架的内部空间分割成三个上下层叠的子腔。该前纵梁在吸收同样碰撞能量前提下,可提供更小的截面尺寸及更稳定的压溃形式。
