Abstract

An active hood apparatus for a vehicle includes a hood configured to cover an engine compartment of vehicle, and at least one hinge device configured to rotatably connect a rear end portion of the hood to a vehicle body. The hinge device includes a fixing bracket fixed to the vehicle body. A rotation bracket is provided such that a rear end thereof is rotatably connected to a rear end portion of the fixing bracket. A hood bracket is fixed to an inner surface of the hood and fixed to the rotation bracket by a first breaking pin. A connecting link provided such that opposite ends thereof are rotatably connected to a rear end portion of the hood bracket and a middle portion of the rotation bracket respectively. An actuator is configured to push up the connecting link in the event that a collision occurs.

Dependent claims

An active hood apparatus for a vehicle, the active hood apparatus comprising:

a hood configured to cover an engine compartment of vehicle;
and
a hinge device configured to rotatably connect a rear end portion of the hood to a vehicle body, wherein the hinge device comprises:
a fixing bracket to be fixed to the vehicle body;
a rotation bracket provided such that a rear end of the rotation bracket is rotatably connected to a rear end portion of the fixing bracket;
a hood bracket fixed to an inner surface of the hood and fixed to the rotation bracket by a first breaking pin;
a connecting link provided such that opposite ends of the connecting link are rotatably connected to a rear end portion of the hood bracket and a middle portion of the rotation bracket, respectively;
an actuator configured to, in response to a collision, push up the connecting link with a force that is sufficient to break the first breaking pin and to raise the hood bracket to a rear upper side by separating the hood bracket from the rotation bracket;
and
a second breaking pin configured to fix the connecting link to the rotation bracket, wherein the active hood apparatus is configured so that when a collision occurs, the actuator pushes up the connecting link with a force that is sufficient to break the first breaking pin and the second breaking pin.

a hood configured to cover an engine compartment of the vehicle;
and
a hinge device configured to rotatably connect a rear end portion of the hood to a vehicle body, wherein the hinge device comprises:
a fixing bracket to be fixed to the vehicle body;
a hood bracket fixed to an inner surface of the hood;
a rear link portion provided such that opposite ends of the rear link portion are rotatably connected to the fixing bracket and the hood bracket, respectively, the rear link portion being configured to be maintained in a folded state since a joint connecting portion provided in the middle of the rear link portion is normally moved to a front side;
a front link portion installed in a more front side than the rear link portion, the front link portion provided such that opposite ends of the front link portion are rotatably connected to the fixing bracket and the hood bracket, respectively, and configured to be maintained in a folded state since a joint connecting portion provided in the middle of the front link portion is normally moved to the front side;
a middle link portion provided such that opposite ends of the middle link portion are rotatably connected to the joint connecting portion of the rear link portion and the joint connecting portion of the front link portion, respectively;
and
an actuator configured to raise the hood bracket to a rear upper side by allowing the rear link portion and the front link portion to be unfolded by pushing up the lower side the front link portion in response to a collision.
