The invention relates to a commercial vehicle front wall energy absorption structure, a frame and a vehicle, the commercial vehicle front wall energy absorption structure comprises a front wall body, the front wall body comprises a front wall baffle and a front wall beam installed on the front wall baffle, a front wall reinforcing cavity is defined by the front wall beam and the front wall baffle, and a floor longitudinal beam installation position is arranged on the side, away from the front wall beam, of the front wall baffle; the part of the front wall beam protrudes and extends towards the side away from the front wall baffle, so that a first local protruding cavity is formed in the front wall reinforcing cavity. The first energy absorption mechanism is located in the first local protruding cavity, and the first energy absorption mechanism is fixed between the front enclosing beam and the floor longitudinal beam installation position. The first local protruding cavity is formed in the front wall reinforcing cavity, the first local protruding cavity can be firstly impacted when a vehicle is collided, the first energy absorption mechanism installed in the first local protruding cavity can absorb part of impact energy after the vehicle is collided, then the first energy absorption mechanism can move to make contact with the floor longitudinal beam, force conduction is achieved, and the energy absorption effect is improved. Therefore, the passive safety of the commercial vehicle is improved.

    本申请涉及一种商用车前围吸能结构、车架及车辆,其包括:前围本体,前围本体包括前围挡板和安装于前围挡板的前围梁,前围梁与前围挡板围成前围加强腔,前围挡板远离前围梁的一侧设有地板纵梁安装位;前围梁的局部朝向远离前围挡板的一侧凸伸,使前围加强腔内形成第一局部凸起腔;第一吸能机构,第一吸能机构位于第一局部凸起腔,且第一吸能机构固定于前围梁与地板纵梁安装位之间。通过在前围加强腔内形成第一局部凸起腔,使车辆在发生碰撞时第一局部凸起腔处可以先受到撞击,安装于第一局部凸起腔内的第一吸能机构能在车辆发生碰撞之后吸收部分撞击能量,此后可以移动至与地板纵梁接触,实现力的传导,从而提升了商用车的被动安全性。
