The invention relates to the technical field of automobile parts, in particular to a rear wall longitudinal beam structure and an automobile. The structure comprises a first longitudinal beam, a second longitudinal beam and a reinforcing plate assembly, wherein at least part of the second longitudinal beam is overlapped with the first longitudinal beam, the second longitudinal beam is connected with the first longitudinal beam to form a U-shaped longitudinal beam groove, and the U-shaped longitudinal beam groove comprises a first section and a second reinforcing section. The reinforcing plate assembly is arranged on the second reinforcing subsection of the U-shaped longitudinal beam groove in a covering mode. By adopting the longitudinal beam structure that the first longitudinal beam and the second longitudinal beam are separately arranged, the width of the section of the beam cavity is not changed, but the material thickness of the beam is doubled. Meanwhile, according to the manufacturing process, an original beam is divided into two split beams, the middle overlapped plane part is divided into two layers, and the two layers can be independently arranged and formed. Due to the fact that the forming difficulty caused by the forming depth of the cross section of the whole beam is avoided, the problems that in the related technology, the requirement for the longitudinal beam stamping process is too high, and batch production and manufacturing are not facilitated are solved.

    本申请涉及汽车部件技术领域,具体涉及一种后围纵梁结构及汽车。该结构包括第一纵梁、第二纵梁和加强板组件;其中,第二纵梁,其至少部分与所述第一纵梁叠置,并与所述第一纵梁相连以形成一个U型纵梁槽,所述U型纵梁槽包括第一分段和第二加强分段。加强板组件,其盖设于所述U型纵梁槽的第二加强分段上。本申请通过采用第一纵梁和第二纵梁分件设置的纵梁结构,梁腔的截面宽度没有变化,但是梁的料厚变为原来的两倍。同时,制造工艺由原来的一根梁,分成两根分件梁,中间重叠平面的部分是两层,可单独设置成型。由于不会因为整体梁截面成型深度导致成型困难,解决了相关技术中,纵梁冲压工艺上的要求过高,不利于批量化生产制造的问题。
