Abstract

A compatible door hinge for vehicles includes a lower plate which has a pin hole and a hinge hole in which a hinge pin and a bushing pin are respectively disposed, an upper plate which is coupled to the lower plate by the hinge pin and can be changed in position relative to the lower plate, and a body plate with which the lower plate and the upper plate are integrated by the bushing pin passing through them. A minimum required setting distance between the door hinge and an upper or lower door skin of a vehicle door can be maintained without changing the design shape of the door skin. Particularly, a door opening trajectory can be formed closer to the door skin and reduced in radius, such that a rotation gap is ensured.

First claim

What is claimed is:

1. A compatible door hinge for vehicles, comprising:
a lower plate having a pin hole in which a hinge pin is disposed, and a hinge hole in which a bushing pin is disposed;
an upper plate having a pin hole in which the hinge pin is disposed so that the upper plate is coupled to the lower plate by the hinge pin, and a hinge hole in which the bushing pin is disposed such that the upper plate can be changed in position relative to the lower plate;
a body plate having an assembly width and allowing coupling portions of the lower and upper plates to be inserted thereinto, the coupling portions being coupled to each other by the hinge pin and having an insert width, the body plate having hinge holes in which the bushing pin is disposed such that the lower plate and the upper plate are integrated with the body plate,
wherein the coupling portions coupled to each other by the hinge pin have an insert coupling structure, and
wherein the insert coupling structure is embodied by a depression shape formed in a bent body of the lower plate and a protrusion shape provided on a bent body of the upper plate.

2. The compatible door hinge of claim 1 , wherein the lower plate comprises: the bent body in which the pin hole and the hinge hole are formed, each of the pin hole and the hinge hole having a circular shape; a position fixing body perpendicularly bent from the bent body, with a bolt hole formed in the position fixing body; and a female boss extending from the bent body and forming the coupling portion to be coupled with the protrusion shape provided on the upper plate, the coupling portion of the female boss having the pin hole and the depression shape formed in the lower plate as an insert slot through which the protrusion shape provided on the upper plate is coupled to the coupling portion of the female boss, and
the upper plate comprises: the bent body in which the pin hole and the hinge hole are formed, each of the pin hole and the hinge hole having a circular shape; an inclined position-fixing body perpendicularly bent from the bent body, with a bolt hole formed in the inclined position-fixing body; and a male boss extending from the bent body and having the pin hole therein, the male boss forming the protrusion shape provided on the upper plate as the coupling portion to be inserted into the insert slot and coupled with the lower plate.

3. The compatible door hinge of claim 2 , wherein the inclined position-fixing body is inclined in one direction with respect to the bent body.

4. The compatible door hinge of claim 1 , wherein the lower plate comprises: the bent body in which the pin hole and the hinge hole are formed, the pin hole being an elongated hole while the hinge hole has a circular shape; a position fixing body perpendicularly bent from the bent body, with a bolt hole formed in the position fixing body; and a female boss extending from the bent body and forming the coupling portion to be coupled with the protrusion shape provided on the upper plate, the coupling portion of the female boss having the pin hole and the depression shape formed in the lower plate as an insert slot through which the protrusion shape provided on the upper plate is coupled to the coupling portion of the female boss, and
the upper plate comprises: the bent body in which the pin hole and the hinge hole are formed, each of the pin hole and the hinge hole being an elongated hole; an inclined position-fixing body perpendicularly bent from the bent body, with a bolt hole formed in the inclined position-fixing body; and a male boss extending from the bent body and having the pin hole therein, the male boss forming the protrusion shape provided on the upper plate as the coupling portion to be inserted into the insert slot and coupled with the lower plate.

5. The compatible door hinge of claim 4 , wherein the elongated holes allow the change in relative position of the upper plate to be performed in a linear section.

6. The compatible door hinge of claim 4 , wherein the inclined position-fixing body is inclined in one direction with respect to the bent body.

7. The compatible door hinge of claim 1 , wherein the assembly width of the body plate is greater than the insert width.

8. The compatible door hinge of claim 7 , wherein the body plate comprises: the bent body which is bent at a right angle; and an insert opening formed in a portion of the bent body and receiving the coupling portions coupled to each other by the hinge pin, wherein the insert opening provides a space for allowing the change in position of the upper plate relative to the lower plate.

9. The compatible door hinge of claim 8 , wherein the bent body comprises upper and lower side extension parts extending along an entire length of the bent body and perpendicularly bent from the bent body, the upper and lower side extension parts forming the assembly width therebetween.

10. The compatible door hinge of claim 1 , wherein the lower plate comprises: the bent body in which the pin hole and the hinge hole are formed, the pin hole being an elongated hole while the hinge hole has a circular shape; a position fixing body perpendicularly bent from the bent body, with a bolt hole formed in the position fixing body; and a female boss extending from the bent body and forming the coupling portion to be coupled with the protrusion shape provided on the upper plate, the coupling portion of the female boss having the pin hole and the depression shape formed in the lower plate as an insert slot through which the protrusion shape provided on the upper plate is coupled to the coupling portion of the female boss, and
the upper plate comprises: the bent body in which the pin hole and the hinge hole are formed, the pin hole being an elongated hole while the hinge hole is an inclined elongated hole; a position-fixing body perpendicularly bent from the bent body, with a bolt hole formed in the position-fixing body; and a male boss extending from the bent body and having the pin hole therein, the male boss forming the protrusion shape provided on the upper plate as the coupling portion to be inserted into the insert slot and coupled with the lower plate,
wherein the assembly width of the body plate is an assembly width increased by a movement clearance.

11. The compatible door hinge of claim 10 , wherein the elongated hole allows the change in relative position of the upper plate to be embodied by angular motion.

12. The compatible door hinge of claim 10 , wherein each of the pin hole of the lower plate and the pin hole of the upper plate is an inclined elongated hole.

13. The compatible door hinge of claim 10 , wherein the inclined position-fixing body is inclined in one direction with respect to the bent body.
