The invention provides an engine cabin housing which comprises an inner plate and an outer plate, the peripheries of the inner plate and the outer plate are mutually lapped and fixed into a whole, and a release cavity is formed between parts outside a lapped area of the inner plate and the outer plate; the middle area of the inner plate is hollowed out to form a lightening hole, the boundary of the lightening hole abuts against and is fixed to the outer plate, and a plurality of buffering supporting pieces are distributed on the inner plate around the lightening hole. Reinforcing metal plates are attached to the four corner areas of the inner plate, and each reinforcing metal plate is provided with a lock catch installation point or a hinge installation point. And each lock catch mounting point, each hinge mounting point and each buffer supporting piece form a closed-loop torsion-resistant route along the periphery of the inner plate. According to the engine cabin cover shell, the torsion resistance can be improved, the problems of noise and stability caused by local vibration can be avoided, and achievement of the NVH index of a whole vehicle is promoted.

    本发明提供了一种发动机机舱罩壳,包括周边相互搭接固定为一体的内板和外板,内板和外板两者搭接区域之外的部位之间形成离型腔;内板的中间区域镂空形成减重孔,减重孔的边界与外板抵贴固定,且内板环绕减重孔分布有多个缓冲支撑件;内板的四个边角区域均贴附有加强钣金,各个加强钣金上分别设有锁扣安装点或铰链安装点;其中,各个锁扣安装点、各个铰链安装点以及各个缓冲支撑件沿内板的周边形成闭环抗扭路线。本发明提供的发动机机舱罩壳,不仅能够提升抗扭性能,还能够避免局部振动而产生噪音和稳定性问题,促进整车NVH指标的达成。
