The invention discloses a rear longitudinal beam structure of an automobile, and relates to the technical field of automobile equipment manufacturing, the rear longitudinal beam structure comprises a front section assembly, a middle section assembly and a rear section assembly, and is characterized in that the rear section assembly comprises a rear section assembly body, the tail end of the rear section assembly body is connected with a first connecting structure of a rear anti-collision beam assembly; and a rear section reinforcing plate piece which is arranged on the rear section assembly, the rear section reinforcing plate piece is flush with the tail end of the rear section assembly body, and the shape and the position of the rear section reinforcing plate piece correspond to those of the first connecting structure. The stiffening plate structure corresponding to the position of the connecting structure of the rear anti-collision beam is arranged for the longitudinal beam structure, and higher strength and collision force resistance are provided for the rear longitudinal beam structure on the premise that excessive weight does not need to be increased. The rear longitudinal beam assembly is divided into three sections, the middle section is not changed in the design, the front end and the rear end are adjusted according to the vehicle type bandwidth, and a design platform is provided for the rear longitudinal beam.

    本发明公开了一种汽车的后纵梁结构,涉及汽车装备制造技术领域,该装置包括前段总成、中段总成和后段总成,其特征在于,所述后段总成包括:后段总成本体,其末端与后防撞梁总成的第一连接结构连接;后段补强板件,其设在所述后段总成上,且所述后段补强板件与所述后段总成本体的末端平齐,所述后段补强板件形状和位置与所述第一连接结构对应。本发明通过为纵梁结构设置与后防撞梁的连接结构位置对应的补强板结构,在不需要增加过多的重量前提下为后纵梁结构提供了更高的强度和碰撞力抵抗能力。本申请将后纵梁总成分为三段,其中段在设计中不做改变,前后两端根据车型带宽进行调整,为后总纵梁提供一个设计平台。
