The invention relates to a vehicle and a front cabin longitudinal beam assembly thereof. The front cabin longitudinal beam assembly of the vehicle comprises a mounting base, a front upper longitudinal beam assembly and a front lower longitudinal beam assembly. And the mounting seat is used for mounting the front anti-collision beam. And the front end of the front upper longitudinal beam assembly is connected with the mounting seat. The front end of the front lower longitudinal beam assembly is connected with the mounting base, and the rear end of the front lower longitudinal beam assembly is connected with the rear end of the front upper longitudinal beam assembly. The front cabin longitudinal beam assembly, the front upper longitudinal beam assembly and the front lower longitudinal beam assembly of the vehicle all extend forwards to the mounting base to be in butt joint with the mounting base, after the front anti-collision beam is mounted on the mounting base, direct butt joint with the front anti-collision beam can be achieved, the backward transmission path of the collision force of the front anti-collision beam is increased, that is, the collision force is not transmitted backwards from the front lower longitudinal beam assembly, and the collision force can be transmitted backwards. And the front upper longitudinal beam assembly is used for transmitting backwards. Besides, the front upper longitudinal beam assembly, the front lower longitudinal beam assembly and the mounting seat are matched to form an energy absorption structure of the safety ring frame, so that the stability during collision is better, and the NVH, rigidity performance and collision performance can be improved.

    本申请涉及一种车辆及其前机舱纵梁总成,车辆的前机舱纵梁总成包括:安装座、前上纵梁组件及前下纵梁组件。安装座用于装设前防撞梁。前上纵梁组件的前端与安装座相连。前下纵梁组件的前端与安装座相连,前下纵梁组件的后端与前上纵梁组件的后端相连。上述的车辆的前机舱纵梁总成,前上纵梁组件、前下纵梁组件均前伸至安装座与安装座对接,在前防撞梁安装于安装座上后,能实现与前防撞梁直接对接,增加前防撞梁的碰撞力往后传递的路径,也即不止从前下纵梁组件向后传递,还通过前上纵梁组件向后传递。此外,前上纵梁组件、前下纵梁组件与安装座三者配合形成安全环框架的吸能结构,使碰撞时稳定性更好,从而能够改善NVH、刚度性能及碰撞性能。
