The invention relates to an active hood hinge, an engine hood assembly and a vehicle, and relates to the technical field of automobile engine hood assembly.The active hood hinge comprises a hinge fixing hinge used for being arranged on a vehicle body; the hinge movable hinge is connected with the hinge fixed hinge, and the hinge movable hinge is used for being connected with an engine hood; and the electromagnetic device is used for enabling the hinge movable leaf to have magnetism under the normal working condition so as to attract the engine hood, and is also used for enabling the hinge movable leaf to lose magnetism so as to be separated from the engine hood when a collision signal is received. When the collision signal is received, the movable hinge loses magnetism and is separated from the engine hood, the bouncing condition of the engine hood is clearer, only the collision signal needs to be received, the bouncing collision force of the engine hood is only related to the force borne by actual collision, the repairability of the engine hood is higher, and the engine hood is more economical; the problems that in the prior art, an engine hood hinge and an engine hood need to be deeply maintained, and the engine hood hinge and the engine hood are difficult to restore rapidly are solved.

    本申请涉及一种主动式机罩铰链、发动机罩总成及车辆,涉及汽车发动机罩装配技术领域,包括铰链固定页,其用于设置在车体上;铰链活动页,其与铰链固定页连接,铰链活动页用于与发动机罩连接;电磁装置,其用于在正常工作情况下使铰链活动页带有磁性,以吸附发动机罩,还用于当接收碰撞信号时,使铰链活动页失去磁性,与发动机罩分离。由于当接收碰撞信号时,铰链活动页失去磁性,与发动机罩分离,发动机罩弹起条件更明确,只需接收碰撞信号,发动机罩弹起碰撞力只与实际碰撞所受的力相关,发动机罩的可修复性更高,更有经济性,解决了现有技术存在需要对发动机罩铰链与发动机罩进行深度维修,难以快速复原发动机罩铰链与发动机罩的问题。
