The present invention relates to a link-type active hinge device for moving the hood of a vehicle backward capable of raising the rear end of a hood quickly and moving the rear end of the hood towards a windshield in case of a collision of a vehicle with a pedestrian in order to relieve impact to the head of the pedestrian and to the hood. The present invention includes: an arm which is combined with a vehicle body fixing bar of a vehicle around a fixing-side hinge axis, wherein a slot hole is formed on a pickup to move the rear end of a hood connected to the pickup towards a windshield and is combined with the guide axis of the arm and a safety pin including a bushing and a combination releasing hole is combined to a combination hole formed on the pickup and the arm to fix the pickup and the arm; and an actuator which operates the combination releasing hole to raise the rear end of the hood quickly and move the rear end of the hood towards the windshield in case of a collision between the vehicle and a pedestrian. According to the present invention, it is possible to simplify the structure of the active hinge device for raising the rear end of the hood, enable firm combination and easy releasing of the arm and the pickup, and improve durability. In particular, when the actuator and the combination releasing hole are operated in case of an accident, by raising the rear end of the hood quickly and moving the rear end of the hood towards the windshield, the present invention is able to reduce possibility of the head of a pedestrian colliding with the edge which is bent for reinforcement and the finish of the rear end of the hood and relieve impact. |
