Claim Text:
1. An active hood hinge device for vehicles, comprising: an actuator bracket rotatably coupled to a mounting bracket of a vehicle body at one side thereof; a locking lever rotatably coupled to the actuator bracket, wherein the locking lever is driven by an operating force of an actuator; a long link rotatably coupled to the actuator bracket, wherein the long link is unfolded and rotated from the actuator bracket by a rotating force of the locking lever; a hood bracket rotatably coupled with the long link and fixedly coupled to a hood panel at opposite sides thereof; a short link engaged with the locking lever at one side thereof and rotatably coupled to the hood bracket at another side thereof, wherein the short link is configured to restrict a motion of the locking lever to maintain an initial state of the locking lever when the actuator is not operated, and to be disconnected from the locking lever to allow the locking lever to rotate when the actuator is operated; and a stopper bracket rotatably coupled to the actuator bracket, wherein the stopper bracket is configured to restrict a motion of the locking lever to maintain an initial state of the locking lever when the actuator is not operated, and to be disconnected from the locking lever so that the stopper bracket rotates when the locking lever rotates as the actuator is operated, wherein the long link and the actuator bracket respectively have a link fixing shaft and a shaft-engaging protrusion to be engaged with the link fixing shaft, to maintain a lifting motion of the hood bracket when the hood bracket is being lifted up as the long link rotates with the operation of the actuator.
