The invention discloses a collision energy absorption protection type automobile engine hood, and relates to the technical field of automobile engine hoods, the collision energy absorption protection type automobile engine hood comprises an automobile engine hood main body, a protection device is movably mounted on the left side in the automobile engine hood main body, and lifting devices are fixedly mounted on the front side and the rear side in the automobile engine hood main body; a stabilizing device is fixedly installed in the middle of the interior of the automobile engine hood body. By installing the protection device, if the front portion of the automobile collides with a pedestrian, a collision ring and a pressing column are made to move, the pressing column starts a button, so that two rotating wheels rotate, two bevel gears are driven to rotate, a movable column moves on a threaded rod, a hood is jacked up through the movable column, the collision ring pushes a first piston to move, and the pedestrian is protected. When a pedestrian is collided, internal gas is completely injected into the air bag, and then the air bag is inflated and opened to the outside, so that the pedestrian can be protected after the pedestrian is collided for the first time, and secondary injury is avoided.

    本发明公开了一种碰撞吸能保护式汽车发动机罩,涉及汽车发动机罩技术领域,包括汽车发动机罩主体,所述汽车发动机罩主体的内部左侧活动安装有保护装置,所述汽车发动机罩主体的内部前后两侧均固定安装有抬升装置,所述汽车发动机罩主体的内部中间位置固定安装有稳定装置。本发明通过安装保护装置,若该汽车的前部撞击到行人,就使得碰撞环和按压柱移动,按压柱将按钮启动,从而使得两个转动轮转动,并带动两个锥齿轮转动,使得活动柱在螺纹杆上移动,并通过活动柱将机罩顶起,碰撞环推动第一活塞移动,内部的气体将全部注入气囊内,随即气囊充气打开到外部,能够在行人遭到第一次撞击后给行人保护,避免二次伤害。
