The invention discloses an engine hood structure, an engine assembly and a vehicle, the engine hood structure comprises an engine hood outer plate, an engine hood inner plate and inner plate reinforcing ribs, the inner plate reinforcing ribs are assembled on the engine hood inner plate, and the engine hood outer plate is arranged on the outer sides of the engine hood inner plate and the inner plate reinforcing ribs; the engine hood inner plate and the inner plate reinforcing ribs are connected through detachable connecting structures. The engine hood structure further comprises a pedestrian collision sensor and a controller. The controller controls connection or separation of the detachable connection structure according to a detection signal of the pedestrian collision sensor. When the pedestrian collision sensor senses that a pedestrian collides with a vehicle, the controller controls the detachable connecting structure to be separated according to a detection signal, so that the inner plate reinforcing ribs are separated from the engine hood inner plate, the overall rigidity of the engine hood structure is rapidly reduced, and the engine hood structure is prone to collapse deformation under the impact of external force; the injury to the head of the pedestrian is reduced.

    本发明公开了一种发动机罩结构、发动机总成和车辆,包括发动机罩外板、发动机罩内板和内板加强筋,内板加强筋装配在发动机罩内板上,发动机罩外板设置在发动机罩内板和内板加强筋的外侧;发动机罩内板和内板加强筋之间通过可拆卸连接结构相连;发动机罩结构还包括行人碰撞传感器和控制器;控制器根据行人碰撞传感器的检测信号,控制可拆卸连接结构的连接或分离。当行人碰撞传感器感应到人车碰撞时,控制器根据该检测信号控制可拆卸连接结构分离,使得内板加强筋与发动机罩内板分离,从而使得发动机罩结构的整体刚度迅速减小,发动机罩结构在外力冲击下,易于溃缩变形,降低行人头部受到的伤害。
