The invention relates to the technical field of automobiles, and discloses a longitudinal beam structure and an automobile. The longitudinal beam structure comprises a longitudinal beam body, a reinforcing plate and an inclined supporting plate, the reinforcing plate is arranged in an inner cavity of the longitudinal beam body; two ends of the reinforcing plate are respectively connected with a transition section and a rear section, two sides of the reinforcing plate are respectively connected with two side walls of the inner cavity, a bent area between the transition section and the rear section is structurally reinforced through the reinforcing plate, and the rigidity and the strength of the area are improved. The reinforcing plate is directly connected to the two side walls of the innercavity, so compared with like structures in the prior art, the longitudinal beam structure of the invention has the following advantages: the size of the reinforcing plate is reduced, and light weight and low cost of the longitudinal beam structure are achieved; and meanwhile, the inclined supporting plate, the transition section and the rear section are arranged to form a triangular supporting structure, and the bending resistance of the longitudinal beam body in the collision process of the transition section and the rear section is effectively enhanced, so a passenger compartment can be prevented from deforming, and the safety of passengers is protected.

    本发明涉及汽车的技术领域,公开了一种纵梁结构和汽车,包括纵梁本体、加强板和斜撑板,加强板设置在纵梁本体的内腔中,加强板的两端分别连接过渡段与后段,加强板的两侧分别连接在内腔的两侧壁,通过加强板对过渡段与后段之间的弯折区域进行结构加强,提高该区域的刚度和强度,而且,由于加强板直接连接在内腔的两侧壁,相较于现有技术,缩小了加强板的尺寸,实现了纵梁结构的轻量化和低成本,同时,通过设置斜撑板与过渡段以及后段形成三角支撑结构,有效增强纵梁本体在过渡段与后段区域在碰撞时的抗弯能力,从而能保持乘员舱不变形,保护乘员的安全。
