The invention relates to a protection device for collision of the head of a pedestrian with a column A. The protection device comprises a pop-up mechanism and a rotating mechanism, when the risk that the head collides with the column A of a vehicle is monitored, the pop-up mechanism pops up from the surface of the column A, deformation energy absorption is achieved, and damage to the head of the pedestrian is reduced; when the head collides with the pop-up mechanism and the stress of the pop-up mechanism exceeds a design threshold value, the rotating mechanism drives the pop-up mechanism to rotate and drives the head to rotate together, the head is pushed to a set area of the front windshield, and the head is prevented from directly colliding with the A column. A pop-up structural design is adopted, the head of a pedestrian is effectively supported and energy is absorbed, and the injury degree of the head is reduced; when the stress of the pop-up structure exceeds a design threshold value, the rotating function is started, the whole protection device rotates, the head is driven to rotate together, the head is pushed to a default area of the front windshield, and the degree of damage to the head can also be reduced. In addition, the pop-up mechanism can be folded to an original state after an accident, so that the maintenance cost is reduced.

    本发明涉及一种行人头部碰撞A柱保护装置,该保护装置,包括弹出机构和旋转机构,监测到头部有撞击车辆A柱的风险时,弹出机构从A柱表面弹出,变形吸能,减小行人头部伤害;头部撞击所述弹出机构,超出弹出结构受力超出设计阈值时,旋转机构驱动弹出机构旋转,带动头部一起旋转,将头部推向前风挡玻璃设定区域,避免头部直接与A柱碰撞。采取弹出式结构设计,对行人头部有效支撑和吸能,降低头部受伤害程度;当弹出结构受力超出设计阈值时,开启旋转功能,使保护装置整体产生旋转,带动头部一起旋转,将头部推向前风挡玻璃默认区域,同样可以降低头部受伤害的程度。此外,事故后弹出机构可以折叠至原始状态,降低了维修成本。
