The invention belongs to the technical field of automobile parts, and particularly relates to an automobile rear longitudinal beam structure, an automobile rear longitudinal beam assembly and an automobile. The automobile rear longitudinal beam structure comprises a rear longitudinal beam body, the front end of the rear longitudinal beam body is bent to form a bent connecting plate used for being connected with an automobile doorsill, and the bent connecting plate comprises a first side plate, a second side plate and a third side plate; wherein the first side plate and the third side plate are located on the two opposite sides of the second side plate; and one end of the second side plate is connected with the first side plate at a first preset angle, and the other end of the second side plate is connected with the third side plate at a second preset angle. According to the rear longitudinal beam structure, the bent connecting plate is tightly connected with the three faces of the automobile threshold, and it is guaranteed that the rear end of the automobile threshold has excellent performance and good rear collision performance; besides, connection between the automobile rear longitudinal beam and the automobile threshold can be realized without additional connecting pieces, so that the weight of the automobile rear longitudinal beam structure is reduced, and the lightweight design of the automobile is facilitated.

    本发明属于汽车零部件技术领域,特别是涉及一种汽车后纵梁结构、总成及汽车。该汽车后纵梁结构包括后纵梁本体,后纵梁本体的前端折弯形成用于连接汽车门槛的折弯连接板,折弯连接板包括第一侧板、第二侧板和第三侧板;第一侧板和第三侧板位于第二侧板的相对两侧;第二侧板的一端与第一侧板与呈第一预设角度连接,第二侧板的另一端与第三侧板呈第二预设角度连接。该后纵梁结构实现了所述折弯连接板与所述汽车门槛三个面的紧密连接,保证了所述汽车门槛后端具有优异性能和良好的后碰性能;且无需另外的连接件即可实现所述汽车后纵梁与所述汽车门槛的连接,进而降低了该汽车后纵梁结构结构的重量,有利于汽车的轻量化设计。
