The embodiment of the invention provides a vehicle front cabin, a vehicle and a vehicle front cabin design method. The vehicle front cabin comprises a front wall plate assembly, two front longitudinal beams and a reinforcing structure. The front wall plate assembly is of an integrated cast aluminum forming structure and comprises a front wall plate body and two connecting beams, and the two connecting beams are arranged on the front side of the front wall plate body at intervals in the left-right direction of the vehicle. The front longitudinal beams extend in the front-back direction of the vehicle, the front longitudinal beams and the front wall plate assembly are of a split structure, the rear end of one front longitudinal beam is connected to one connecting beam, and the rear end of the other front longitudinal beam is connected to the other connecting beam. The ratio of the length of the connecting beam in the front-back direction of the vehicle to the length of the front longitudinal beam in the front-back direction of the vehicle is 1/3-1/2; the reinforcing structure is arranged on the front wall plate assembly and/or the front longitudinal beam and used for structurally reinforcing at least one part of the front wall plate assembly and the front longitudinal beam. The front longitudinal beam and the front wall plate assembly are of a split structure, so that the design freedom degree of the front longitudinal beam is higher.
本申请实施例提供一种车辆前机舱、车辆及车辆前机舱设计方法。车辆前机舱包括前壁板总成、两个前纵梁和加强结构。前壁板总成为一体铸铝成型结构,前壁板总成包括前壁板本体和两个连接梁,两个连接梁沿车辆的左右方向间隔设于前壁板本体的前侧;前纵梁沿车辆的前后方向延伸,前纵梁与前壁板总成为分体式结构,且其中一个前纵梁的后端连接于其中一个连接梁,另一个前纵梁的后端连接于另一个连接梁;连接梁沿车辆前后方向的长度与前纵梁沿车辆前后方向的长度的比值为1/3~1/2;加强结构设置于前壁板总成和/或前纵梁,用于对前壁板总成、前纵梁中的至少一者的局部进行结构加强。前纵梁与前壁板总成为分体式结构,使得前纵梁的设计自由度更高。
