The present invention relates to a door hinge, and more particularly, to a door hinge having a function as a hinge for supporting the door to be opened and closed and a function as a checker to keep the door open at a predetermined angle so as not to open the door over a predetermined range. It is about.

(Prior art)

The door of a vehicle provided for entry and exit of passengers and cargoes has a structure in which two steel plates, which have been press-processed, are welded in a box shape, and the door is provided to be opened and closed to the vehicle body by a door hinge. Since the door includes not only the weight of the inner and outer panels, but also the door opening and closing device for opening and closing the door, the door locking device, the window glass and the window glass opening and closing device, the door trim and various switches, etc., the door itself has a considerable weight. Since such heavy door is entirely supported by the frame of the vehicle body, i.e., the hinge which keeps the door open and close to the pillar panel, the hinge receives a considerable load.

On the other hand, between the door and the body of the door to keep the door open by a predetermined angle while preventing the door to open more than a predetermined limit to facilitate opening and closing of the door and a door checker that bears a part of the load that the door hinge receives between the door hinge It is installed.

In general, one door hinge is provided at the upper and lower parts of the door, and a door checker is provided between the doors. That is, the door hinge and the door checker are conventionally formed separately.

3 is a perspective view of a conventional general door hinge, and FIG. 4 is a perspective view of a conventional general door checker. As shown in FIG. 3, the conventional door hinge 51 has a female hinge 53 bolted to a filler panel and a mail hinge 55 bolted to a door panel by a hinge shaft 57. It consists of a structure that is rotatably coupled.

In addition, the conventional door checker 61 includes a door checker housing 63 and a checker 65 inserted into the passage, the door checker housing 63 being formed so as to penetrate through the door checker passage formed at a door checker insertion hole formed in the door panel. It consists of a checker fixture 67 connected by the checker 65 and the checker pin 69 and attached to the filler panel.

Thus, since the conventional door hinge and the door check are separately configured, the assembly and disassembly process is cumbersome and the required parts are excessively expensive, and the manufacturing cost is excessive. In particular, the door check is checked every time the door is opened or closed. ) Has a problem that significant noise occurs because it enters and exits the passage of the checker housing 63.

Accordingly, an object of the present invention is to solve the problem of the conventional structure in which the door hinge and the door checker are formed independently, and by constructing the door hinge and the door check into one integrated structure, improving the assemblability and noise To reduce the occurrence and to reduce the cost.

The object of the present invention is to attach a bent spring to the female hinge at the door hinge is coupled to the female hinge (male hinge) and the male hinge (male hinge) by the hinge axis, It is achieved by a door hinge with a checker function that forms a checker plate that contacts the round part of the leaf spring and limits the opening and closing of the door.

Specifically, an object of the present invention is a door hinge in which a female hinge and a female hinge are rotatably coupled by a hinge shaft, wherein the female hinge has a rounded portion that is bent toward a hinge shaft between the hinge shaft and the hinge shaft. The leaf spring is formed in the transverse direction, the mail hinge is formed with a rounded portion bent toward the leaf spring, and a checker plate facing the leaf spring is formed, and the mail hinge rotates about the hinge axis. The rotation of the mail hinge is limited in a certain range by the interaction of the round portion of the checker plate with the round portion of the leaf spring, and is achieved by a door hinge with a checker function.

Hereinafter, a door hinge having a checker function according to the present invention will be described in detail with reference to the accompanying drawings. The following specific examples merely illustrate the door hinge with a checker function according to the present invention, but do not limit the scope of the present invention.

1 is a perspective view showing a door hinge with a checker function according to the present invention, Figure 2 is an exploded perspective view of a door hinge with a checker function according to the present invention. As shown, the door hinge 1 with the checker function according to the present invention, like the conventional hinge, allows the female hinge 3 and the mail hinge 5 to be rotatable by the hinge shaft 7. Has a basic configuration combined.

The female hinge 3 protrudes on both ends of the base 9 and the base 9 on which the bolt hole 11 for fastening it to the filler panel is formed, and is connected to the mail hinge by the hinge shaft 7. 5) includes a hinge shaft support 13 for engaging.

The mail hinge 5 is a fastening portion 17 in which a hinge 15 is rotatably supported by the hinge shaft 7 in the hinge shaft support 13 and a bolt hole 19 for fastening to the door panel is formed. It consists of).

According to a feature of the invention, the female hinge 3 is provided with a leaf spring 21 in the transverse direction between the hinge shaft 7. The leaf spring 21 has one end 23 fixed to the hinge shaft support 13 side of the female hinge 3, and the other end 25 extends into the base 9. The other end 25 is a free end that is not fixed to the base 9.

The leaf spring 21 is formed with a rounded portion 27 that is bent toward the hinge shaft 7. Therefore, when a predetermined force is applied to the round portion 27 of the leaf spring 21, the round portion is elastically deformed according to the magnitude or direction of the force by the elasticity of the leaf spring 21 to receive the force or repel the force. do. The leaf spring 21 may be formed of a steel having a separate elasticity and attached to the female hinge 3 by welding or screwing, or may be integrally formed when the female hinge 3 is formed. .

The checker plate 31 is integrally formed in the base 15 with the leaf hinge 5 facing the leaf spring 21. The checker plate 31 is positioned in the horizontal direction with a length and a width corresponding to the position corresponding to the leaf spring 21, and the round portion 33 is bent toward the leaf spring 21 is formed. The checker plate 31 is made of a strong material that is not easily deformed.

Therefore, when the mail hinge 5 rotates the hinge shaft 7 to the axis, the checker plate 31 also rotates together so that the round part 33 of the checker plate 31 rounds the plate spring 21. The part 27 is pressed. As a result, the interaction of the round part 33 of the checker plate 31 and the round part 27 of the leaf spring 21 allows the rotation of the mail hinge 5 to be free or limited in a certain angle range.

That is, by appropriately forming the bends of the round portion 33 of the checker plate 31 and the round portion 27 of the leaf spring 21, the plate spring 21 is the checker plate 31 until the door is opened to some extent. Without limiting the rotation of), the leaf spring 21 elastically restricts the rotation of the checker plate 31 so that the door is no longer opened. In addition, the door may maintain the opening angle at the most preferable door opening angle according to the shape of the round parts 27 and 33.

The checker plate 31 may also be formed of a separate steel like the plate spring 21 and attached to the mail hinge 5 by welding or screwing, or may be integrally formed when the mail hinge 5 is formed. have.

Here, the leaf spring 21 should be such that it does not lose its elasticity or deform even when the door is repeated by using a steel spring having a strong elasticity.

According to the door hinge with a checker function according to the present invention described above, a bent spring spring is attached to the female hinge, the checker for limiting the opening and closing of the door while contacting the round portion of the leaf spring According to the door hinge structure with the plated checker function, since the door hinge and the door checker are composed of one integrated structure, the door hinge and the door checker can be assembled in a single process, and the noise caused by the check-in and out of the checker There is no fear of occurrence, and the cost is reduced.
