The invention relates to a rear floor framework longitudinal beam, a rear floor framework, a lower vehicle body assembly and a vehicle. The rear floor framework longitudinal beam comprises a longitudinal beam body and longitudinal beam reinforcing ribs. The longitudinal beam reinforcing ribs comprise first reinforcing ribs and second reinforcing ribs, the first reinforcing ribs extend in the height direction of the longitudinal beam body, and the second reinforcing ribs extend in the length direction of the longitudinal beam body and intersect with the first reinforcing ribs. The longitudinal beam reinforcing ribs are arranged on one side of the longitudinal beam body, so that the structural strength of the rear floor framework longitudinal beam is improved, the first reinforcing ribs extend in the height direction of the longitudinal beam body so as to bear transmission of force in the height direction of a vehicle, and the second reinforcing ribs extend in the length direction of the vehicle so as to bear transmission of force in the length direction of the vehicle. That is, the longitudinal beam reinforcing ribs can be used for reliably transmitting force together with the longitudinal beam body, so that the overall structural strength of the rear floor framework longitudinal beam is remarkably improved.
本公开涉及一种后地板骨架纵梁、后地板骨架、下车体总成以车辆,后地板骨架纵梁包括纵梁本体及纵梁加强筋;纵梁加强筋包括第一加强筋和第二加强筋,第一加强筋沿纵梁本体的高度方向延伸,第二加强筋沿纵梁本体的长度方向延伸且与第一加强筋相交。通过在纵梁本体的一侧设置纵梁加强筋,从而提升后地板骨架纵梁的结构强度,第一加强筋沿纵梁本体的高度方向延伸,以承受车辆的高度方向上的力的传递,第二加强筋沿着车辆的长度方向延伸,以承受车辆的长度方向上的力的传递,即纵梁加强筋可用于与纵梁本体共同实现力的可靠传递,以此实现后地板骨架纵梁的整体结构强度的显著提升。
