Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air guide operating device for an automobile hood, wherein an air guide (9) is rotatably mounted to a bracket (8) on a bottom surface of a hood (7), and is fixed to a front lower end of the air guide (9). (10) is fitted into the guide groove (6a) of the second pivot lever (6), the second pivot lever (6) to the collision detection lever (2) rotated by the deformation of the bumper cover (1) in the event of a collision It consists of a structure that is rotated by the interlocking action of the first rod (3), the first pivot lever (4), the second rod (5) to be interlocked.

Therefore, when the collision detection lever 2 is rotated at the same time as the collision, the second pivot lever 6 is rotated counterclockwise through a series of interlocking actions, wherein the pin 10 is guide groove 6a. By moving downward along the air guide 9 is rotated downward to protrude the protruding part.

Therefore, at the same time as the collision, the air guide 9 is leaned on the same plane as the hood 7, so that there is no protruding portion on the upper portion of the hood 7, so that the body of the pedestrian injured by the collision There is no part to be caught when passing through the upper surface has the effect of solving the secondary injury problem caused by the air guide.

Description

An air guide operating device of hood in a vehicle}

The present invention relates to an air guide of a car hood, and more particularly to an air guide operating device of the car hood that can prevent the secondary injury of the pedestrian caused by the air guide during the pedestrian collision.

In general, the hood of the vehicle consists of a flat panel, but in the vehicle equipped with an intercooler, an air guide is formed for smooth air inflow to the intercooler.

FIG. 1 is a cross-sectional view of a hood in which the air guide is formed, and the air guide 120 is formed in a shape in which a portion of the hood 110 above the intercooler 100 protrudes upward and the front side is opened.

Therefore, since a large amount of air is easily introduced through the air guide 120 while driving, the air suction efficiency to the intercooler 100 is improved.

However, the air guide 120 has a safety problem in the case of a pedestrian collision accident of the vehicle.

That is, when a car and a pedestrian collide in front, if the path of the pedestrian's body passes through the upper part of the hood after the collision, the pedestrian's body collides with the air guide 120 to be injured in addition to the injury caused by the first collision. There is a problem that can be increased because the degree of injury.

Therefore, the present invention has been invented to solve the above problems, when a collision accident occurs, the installation state of the air guide is changed, even if the body of the pedestrian proceeds on the top surface of the hood after the collision by the collision with the air guide It is an object of the present invention to provide an air guide actuator of a car hood that is not injured.

The present invention for achieving the above object, the collision detection lever rotated by receiving the impact force by the deformation of the bumper cover, a first rod hinged to the upper end of the collision detection lever, and the other end of the first rod A first pivot lever hinged and rotatably mounted about the central axis, a second rod hinged to the first pivot lever, hinged to the second rod, the intermediate portion pivotably fixed, and an air guide when rotating The guide groove is formed to guide the pin fixed downward at the bottom of the second rotation lever and the locking jaw formed on the locking jaw formed on the lower surface of the hood at the front of the upper portion, and mounted on the lower surface of the hood behind the air guide installation Bracket, an air guide hinged to the bracket so as to be rotatable, a pin and an upper portion mounted to the front lower end of the air guide and inserted into the guide groove of the second pivoting lever. It includes a spring that pulls the air guide.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

2 is a configuration diagram of an air guide operating device according to the present invention, wherein the collision detection lever 2 is rotatably mounted about a fixed part in a state where the lower end is in contact with the inner surface of the bumper cover 1. A first rod 3 is hinged to an upper end of the collision detection lever 2, and a rear end of the first rod 3 is an upper end of the first pivot lever 4 rotatably installed around a central fixing part. The second rod 5 is hingedly connected to the lower end of the first pivot lever 4, and the rear end of the second rod 5 is connected to the lower end 6b of the second pivot lever 6. The hinge is connected.

The second pivotal lever 6 is rotatable in the center of the second pivoting lever 6 through a fixing means such as a pin, and a guide groove 6a is formed along a curved end of the upper portion, and a latching jaw bent backward at the front upper end ( 6c) is formed, and in the mounted state, the catching jaw 6c is caught by the catching jaw 7a formed at the rear end lower surface of the front hood 7 at the air guide installation position.

On the other hand, a bracket 8 is mounted on the front lower surface of the rear hood 7 at the air guide installation position, and the rear end of the air guide 9 is rotatably fixed to the upper portion of the bracket 8. A pin 10 is provided at the front lower end of the pin 9, and the pin 10 is inserted into the guide groove 6a of the second pivoting lever 6, and the middle lower surface of the air guide 9 and the bracket Between the front ends of the (8) is provided a spring 11 for pulling the air guide 9 downward.

The operation of the present invention will be described below.

In the normal state in which the collision does not occur, the second pivoting lever 6 is in a state in which the engaging jaw 6c is caught by the engaging jaw 7a of the hood 7, and in this state, the pin of the air guide 9 Since the 10) is located at the upper portion of the guide groove 6a, the air guide 9 protrudes upward of the hood 7 to perform this function of inflowing outside air through the front opening.

However, when a collision with a pedestrian occurs while driving a vehicle, the bumper cover 1 is pushed backward or deformed so that the collision detection lever 2 which is in contact with the lower end thereof is rotated counterclockwise, and the collision detection lever 2 is rotated. As it is rotated, the first rod 3 is pulled to rotate the first pivot lever 4 counterclockwise, and the lower end of the first pivot lever 4 pushes the second rod 5 backward. Push the lower end 6b of the two-turn lever 6 backward.

Accordingly, the second pivot lever 6 is rotated counterclockwise, and the locking jaw 6c of the second pivot lever 6 is separated from the locking jaw 7a of the hood 7.

As described above, the second rotation lever 6 is rotated counterclockwise and the spring 11 is pulled by the air guide 9 so that the pin 10 of the air guide 9 is formed in the guide groove 6a. It moves to the inner bottom, whereby the air guide 9 is located on the same plane as the hood 7 by lowering the protruding front upper part by rotating downward about the fixing point of the bracket 8.

That is, in the event of a collision, the air guide 9 is leaned toward the hood 7 at the same time as the collision, so that no part protrudes upward on the upper surface of the hood 7, so that the body of the pedestrian after the collision lifts the upper surface of the hood 7. There is no jam when moving along the path, so the air guide is not injured further.

As described above, according to the present invention, when the collision with the pedestrian, the lower end of the air guide is moved downward along the guide groove of the second pivoting rod so that the air guide can be pulled to the inside of the hood at the same time as the collision. Even if the body of the injured pedestrian moves to the upper portion of the hood, there is no part to be collided or caught again when moving, thereby eliminating the phenomenon of secondary injury caused by the conventional air guide.
