The invention discloses a locomotive hood structure and a locomotive. The locomotive head cover structure comprises a head cover main body, the head cover main body is divided into a plurality of sections which at least comprise a first section and a second section, the first section and the second section are connected with each other, the head cover main body structures of the first section and the second section are different layered structures, the second section is provided with a reinforcing layer, a first outer layer, a first sandwich layer, a reinforcing layer and a first inner layer are sequentially arranged from outside to inside, the first section is arranged at the two side faces of a cab, the third section is arranged in the view area of a driver, the fourth section is arranged at the front end of the cab, and the second section is provided with the reinforcing layer to improve the safety design; the first section, the third section and the fourth section do not need reinforcing layers and can be designed in a light weight mode, a plurality of connecting points or reinforcing ribs are arranged on the side faces and the top, in this way, the strength of the hood can be improved, meanwhile, the light weight design is achieved, grading failure is achieved during collision, and the maintenance cost can be reduced under the certain collision condition.

    本发明公开了一种机车头罩结构及机车,机车头罩结构包括头罩主体,头罩主体分为多区段,至少包括第一区段与第二区段,第一区段与第二区段相互连接,第一区段与第二区段的头罩主体结构为不同的层状结构,第二区段具有加强层,由外至内依次设置的第一外层、第一夹心层、加强层和第一内层,第一区段设于司机室两侧面,第三区段设于司机视野区,第四区段设置于司机室前端,其中第二个区段通过设置加强层提高安全设计,第一区段、第三区段、第四区段可以不要加强层,可轻量化设计,还在侧面及顶部设置多个连接点或加强筋,这样可满足既提升了头罩强度的同时,实现了轻量化设计,同时在发生碰撞时分级失效,在一定的碰撞情况下可减少维修成本。
