The longitudinal beam connecting structure comprises a longitudinal beam, a connecting beam, a first supporting beam, a second supporting beam, a threshold beam and a column A. The two ends of the first supporting beam are provided with a first connecting end and a second connecting end respectively, the first connecting end is connected with the side face of the rear portion of the longitudinal beam, and the second connecting end is connected with the column A. The second supporting beam is arranged between the connecting beam and the doorsill beam, a third connecting end and a fourth connecting end are arranged at the two ends of the second supporting beam respectively, the third connecting end is connected with the side face of the connecting beam, and the fourth connecting end is connected with the front side face of the doorsill beam; in the vertical direction, the projection of the first supporting beam and the projection of the second supporting beam are of a crossed structure. By arranging the first supporting beam and the second supporting beam, the force transmission path between the longitudinal beam and the doorsill beam is increased, the force transmission effect is optimized, force transmission is smoother, damage of external impact force to the whole vehicle is reduced, and the torsion performance of the whole vehicle is effectively improved through the first supporting beam and the second supporting beam which are arranged in a crossed mode.
本发明公开一种纵梁连接结构和具有其的车辆,包括纵梁、连接梁、第一支撑梁、第二支撑梁、门槛梁和A柱,第一支撑梁的两端分别设置有第一连接端和第二连接端,第一连接端与纵梁的后部侧面相连,第二连接端与A柱相连,第二支撑梁设置在连接梁与门槛梁之间,第二支撑梁的两端分别设置有第三连接端和第四连接端,第三连接端与连接梁的侧面相连,第四连接端与门槛梁的前部侧面相连;在上下方向上,第一支撑梁与第二支撑梁的投影呈交叉结构。通过设置第一支撑梁和第二支撑梁,增加了纵梁和门槛梁之间的传力路径,优化了传力效果,使得力的传递更加顺畅,从而减小外部冲击力对整车的伤害,交叉设置的第一支撑梁和第二支撑梁有效提升了整车的扭转性能。
