Description

[0001] The present invention relates to an active hinge operation structure for a vehicle,

The present invention relates to an active hinge actuating structure for an automobile, and more particularly, to an active hinge actuating structure for an automobile which is installed between a hood of a vehicle and a vehicle body and moves the hood upward to protect a pedestrian in a frontal collision of the vehicle, When the frontal collision of the vehicle occurs, the actuator hinge link and the active hinge link fixing pin, which have fixed the hood bracket, are moved away from the active hinge link and the hood bracket by the actuator piston to raise the hood end, And more particularly, to an active hinge actuating structure for an automobile which can protect pedestrians colliding with the front.

Active hinges are being installed on the hood of a vehicle to meet pedestrian-related regulations and Euro NCAP-related injuries to the head of a pedestrian.

When the pedestrian collides with the front of the vehicle, the active hinge raises the hood in the front glass direction of the vehicle and reduces the impact of the pedestrian's head against the windshield.

That is, the active hinge recognizes a pedestrian collision through a pedestrian identification sensor attached to the front impact beam, and raises the active hinge by using an actuator (mechanical or simplified) within a short time.

As a result, the hood is separated from the engine room, and the injury value of the head part of the pedestrian is lowered.

However, when the hood is opened for maintenance, the active hinge must be the center of rotation of the hood, and when the head is to be protected during a pedestrian collision, the latch in front of the hood must be the center of rotation.

For this purpose, a part of the link of the active hinge is fixed, and the fixed link is released when the active hinge is deployed due to the forward collision.

At this time, the fixing member for fixing the active hinge link is mainly made of plastic, and the hood rises as the plastic is broken when the vehicle collides in front.

However, such an active hinge actuating structure for a vehicle has the following problems.

That is, plastic, which is a fixing member for fixing the link of the active hinge at normal times, is subjected to a concentrated load, and a fatigue load due to hardening or the like is generated over time and is damaged due to opening of the hood for maintenance or impact during running There was a problem.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an actuator hinge link fixation pin that fixes an active hinge link and a hood bracket while an actuator piston rises when a frontal collision occurs in a vehicle so as to protect a pedestrian colliding with the front of the vehicle, The plastic, which is a fixing member for fixing the link of the active hinge, is subjected to a concentrated load by lifting the hood end while releasing from the active hinge link and the hood bracket, and a fatigue load due to hardening or the like occurs over time Which can effectively solve the problems of opening the hood for maintenance or being damaged due to impact during traveling, and to provide an operating structure for an active hinge for an automobile.

The present invention relates to an active hinge actuating structure for an automobile which is installed between a hood of a car and a vehicle body and moves the hood upward to protect the pedestrian in the event of a frontal collision of the vehicle, wherein a hinge bracket flange, And an active hinge link front end hinge portion formed at one end of the hinge bracket is coupled to the hinge bracket hinge portion of the hinge bracket and the hinge bracket fixing pin so as to be able to flow, An active hinge link provided with a link rear hinge portion and an active hinge link mounting hole adjacent to a rear hinge portion of the active hinge link, and a hood bracket flange formed at an upper portion thereof fixedly coupled to a lower one side of the hood, The active hinge link rear hinge portion and the active hinge link portion A hood bracket movably coupled to the link fixing pin and having a hood bracket mounting hole corresponding to the active hinge link mounting hole of the active hinge link and a hood bracket installed in the active hinge link mounting hole of the active hinge link and a hood bracket mounting hole of the hood bracket, An active hinge link fixing pin having a rear surface fixed to the active hinge link fixing pin mounting hole and a front surface formed with an inclined portion, and an actuator for pushing the active hinge link fixing pin in a forward collision of the vehicle and raising the hood, And an actuator provided so that the piston can move upwards.

And an elastic hinge link fixing pin provided at one side of the active hinge link and having one end fixedly coupled to the active hinge link and the other end supporting the rear surface of the latching jaw of the active hinge link fixing pin, The active hinge link fixing pin can be prevented from being lost when the hinge link is detached from the hood bracket mounting hole of the active hinge link fitting hole and the hood bracket by the rise of the piston, And the other end of the active hinge link fixing pin is formed to have a bending portion in a bending spring supporting the rear surface of the engaging jaw of the active hinge link fixing pin so that the bending spring can be firmly fixed to one side of the active hinge link. It is.

The present invention relates to an active hinge actuating structure for a vehicle which is installed between a hood of an automobile and a vehicle body and which moves the hood upward to protect a pedestrian when the vehicle is in a frontal collision, The active hinge link fixing pin, which has been fixed to the active hinge link and the hood bracket, is lifted from the active hinge link and the hood bracket by the actuator piston to raise the hood end, thereby protecting the pedestrian colliding with the front of the vehicle will be.

Particularly, by not using plastic, which is a fixing member for fixing the link of the active hinge, there is also an effect that the hood is firmly fixed to the vehicle body at normal times.
