DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an open effort assist hood hinge will be described in detail with reference to the accompanying drawings.

The present invention is formed of a metallic material, and a mounting frame (1) is formed to serve as a supporting member so that the present invention can be mounted on a vehicle and the structure of the present invention can be installed.

The mounting frame 1 can be bolted by forming coupling holes on both sides of the lower surface so that the lower surface of the mounting frame 1 can be tightly attached to the vehicle body and can be bolted to one side, So that the components can secure space for joining.

A mounting portion 2 is formed at a side rear end of the mounting frame 1 and has a shape bent and protruded inward of the mounting frame 1. When the hood is closed, 2 ') so that the lower portion of the first link 11 can be stably supported.

A driven link portion 10 for hinging the hood coupling means 3 to be engaged with the rear end of the hood 30 is provided on a side surface of the mounting frame 1.

The first link 11 is composed of a first link 11 and a second link 12. The first link 11, which is elongated in the longitudinal direction and formed in the form of a bar having a small width and a small thickness, Is rivetted with the side surface of the mounting frame 1 in such a manner that the center portion is located at the upper side of the front side of the seating portion 2 so as to be completely in close contact with the damper 2 'provided at the upper portion of the seating portion 2 To be rotatable with a small radius,

The second link 12, which is formed in the shape of a long and thin rod like the first link 11, is riveted to the upper side of the side surface of the mounting frame 1 so as to be rotatable with a large radius.

One end of the first link 11 and the other end of the second link 12 are coupled to the rear end of the hood coupling 3 so that the hood coupling 3 can hinge.

The driven link portion 10 and the hood coupling means 3 combined as described above are configured such that when the hood 30 coupled with the hood coupling means 3 is lifted, the first link 11 The hood 30 is opened by rotating the first link 12 and the second link 12. The stopper 4 is formed at the lower end of the rear end of the hood coupling 3 so as to bend inward Do not allow the hood to open over a certain angle.

The other end of the first link 11 coupled to the hood coupling 3 rotates through opening and closing of the hood. The other end of the first link 11 is connected to the driving link 20 ).

The driving link portion 20 is riveted and rotatable in a state where one side of the third link 21 formed in a short and thin rod shape and one side of the fourth link 22 are spaced apart from each other by a predetermined distance, The spring 23 is connected to the third link 21 and the fourth link 22 so that the spring 23 can generate an elastic force when the angle between the third link 21 and the fourth link 22 becomes less than 180 degrees.

One end of the third link 21 constituting the driving link 20 is riveted to one end of the first link 11 and one end of the fourth link 22 is connected to the end of the mounting frame 1 So that an angle between the third link 21 and the fourth link 22 is opened when the hood is opened, and the angle of closing the hood can be narrowed.

Hereinafter, the operation of the present invention will be described.

First, when the user lifts the hood 30 of the vehicle, the first link 11 is rotated in the counterclockwise direction with respect to the center by rotating the hood engagement opening 3, and the second link 12 is rotated So that the hood 30 is opened.

Since the first link 11 rotates with a small radius and the second link 12 rotates with respect to the end, the first link 11 rotates with a large radius, so that even if the hood 30 is slightly opened, The link 11 is rotated at a large angle.

The driving link portion 20 coupled to one end of the first link 11 maintains a state in which the driving link portion 20 is opened by an elastic force of the spring 23 when the angle is less than 180 degrees, And the other end of the third link 21 is connected to the lower end of the front end of the mounting frame 1 so as to be rotatable in a state where it is fixed to the side face of the mounting frame 1, The direction of the force transmitting the elastic force to the first link 11 is changed according to the angle of the first link 11. [

In detail, when the hood 30 is closed, the first link 11 is completely separated. At this time, the driving link portion 20 lifts the end of the first link 11 upward, The force is generated in the form of rotating. The first link 11 is completely in close contact with the damper 2 'installed on the upper portion of the seat portion 2. Since the first link 11 is no longer rotated by the damper 2', the hood 30 is firmly closed .

When the hood 30 is slightly lifted by the user, the first link 11 rotates a large number of angles. At this time, when the first link 11 is rotated by a predetermined angle or more, The elastic force of the spring 23 is transmitted to the hood 30 through the hood 30 so that the hood 30 can be easily opened. So that the user can open the hood 30 even with a small force.

When the hood 30 is completely opened, the stopper 4 formed at the rear end of the hood coupling 3 abuts against the surface of the second link 12, so that the hood coupling 3 is not completely rotated So that it is possible to keep the hood 30 fully open by the elasticity of the spring 23 without any other mounting means.

In addition, when the hood 30 is closed, the hood 30 can be prevented from suddenly closing due to the elasticity of the spring 23, so that a safety accident can be prevented. It is possible to absorb the shock generated at the rear end of the hood 30 by the damper 2 'when the hood 30 is closed, thereby preventing the link joint of the hood hinge of the present invention from being damaged by a sudden impact.

The unexplained reference numeral 40 in the drawing denotes a vehicle.
