The invention discloses an active hinge device, an engine hood and an automobile. The active hinge device comprises a hinge automobile body connecting base, a hinge jacking arm, a hinge rotating arm, an engine hood mounting bracket and a jacking arm limiting arm, one end of the hinge jacking arm is rotationally connected with one end of the hinge rotating arm, and the other end of the hinge jacking arm is in limiting sliding connection with the hinge vehicle body connecting base through a limiting protruding column. The other end of the hinge rotating arm is rotatably connected with the engine hood mounting bracket; the jacking arm limiting arm is connected to the plane of the hinge vehicle body connecting base through a shaft, and the end of the jacking arm limiting arm can make contact with the side wall of the limiting protruding column in a limiting mode. When collision occurs, the rear end of the engine hood can be lifted by a certain height and moves backwards by a certain distance in cooperation with the jacking device, when the head of a pedestrian collides with a front windshield, due to the fact that the engine hood moves backwards by a certain amount, a part of the front windshield is shielded, the head of the pedestrian is blocked by the engine hood to deform and absorb energy, and the safety of the pedestrian is improved. Therefore, pedestrians can be well protected.

    本发明公开了一种主动铰链装置、发动机罩及汽车,包括铰链车身连接底座、铰链顶升臂、铰链旋转臂、发动机罩安装支架以及顶升臂限位臂;铰链顶升臂一端与铰链旋转臂的一端转动连接,铰链顶升臂另一端通过限位突柱与铰链车身连接底座限位滑动连接;铰链旋转臂的另一端与发动机罩安装支架可转动连接;顶升臂限位臂轴连接于铰链车身连接底座平面上,且顶升臂限位臂端部可限位触接于限位突柱侧壁上;本发明可在碰撞发生时配合顶升器将发动机罩后端抬起一定高度并向后进行一定距离的位移,当行人头部碰撞向前挡风玻璃时,由于发动机罩向后进行了一定量的位移,遮挡了一部分前挡风玻璃,使行人头部被发动机罩阻挡形变吸能,从而较好的保护行人。
