Description

Door hinge mounting stucture utilization square pin for position fixing

The present invention relates to a door hinge coupling structure using a square pin for fixing a position to prevent assembly scattering when the vehicle body door is mounted. More specifically, the present invention relates to a door hinge coupling structure formed on a first door hinge attached to an outer side panel side of a vehicle body. The present invention relates to a door hinge coupling structure using a position fixing square pin that inserts a position fixing square pin that performs a jig role between the through holes, thereby solving a problem in that assembly scattering occurs due to a clearance gap when assembling the body door.

In general, a plurality of doors are installed in a vehicle so as to be opened and closed by using a door hinge.

The door adjusts a gap with the vehicle body in a state in which the door is mounted on the vehicle body before inputting the design line, and transfers the vehicle body in which the door is mounted to the design process.

When the vehicle body equipped with the door is transferred to the design line through the painting line, after the door is separated again, the door performs separate design work, and the body completes the design work without the door, and then the door Will be attached to the

1 is a view showing a position in which a door hinge for opening and closing a door in a typical vehicle is mounted, Figure 2 is a front view showing a conventional door hinge, Figure 3 is a cross-sectional view of the AA portion in Figure 2 It is a cross section.

As shown in the drawing, the door hinge 1 supporting the door to be opened and closed is a first door hinge fixed to the outer side panel 2 side (part A) of the vehicle body via a fixing bolt 3. 4) and the second door hinge 5 which is rotatably coupled to the first door hinge 4 and the rotation shaft 6 and fixed to the door (not shown).

As shown in FIG. 3, two through holes 7 are formed on the first door hinge 4, and the first door hinge 4 is coupled to the outer side panel 2. It is composed of a fixing bolt (3) inserted into the through hole (7) for bolting the outer side panel (2) and the first door hinge (4).

When the outer side panel 2 and the first door hinge 4 are coupled between the fixing bolt 3 and the through hole 7, a predetermined size (about 1.5 mm) is provided for smooth assembly of the fixing bolt 3. The clearance G is formed in the up-down, left-right direction.

That is, when the size of the through hole 7 is set equal to the size of the fixing bolt 3, a problem occurs in that the door cannot be mounted, so there is a play between the through hole 7 and the fixing bolt 7. It is to put.

However, the existing door hinge having the above configuration is parted due to the clearance between the fixing bolt and the through hole formed on the first door hinge when the first door hinge is mounted to the outer side panel via the fixing bolt. There are problems such as unevenness of the gap and change of the sealing gap.

An object of the present invention devised to solve the problems as described above is the occurrence of assembly scattering, such as the variation of the sealing gap and the variation of the sealing gap caused by the gap formed between the door hinge and the fixing bolt during assembly of the door To restrain it.

In order to achieve the object of the present invention as described above, the second pin is formed between the two through-holes formed on the door hinge, and the pins for fixing the position of the pins are inserted into the pins to fix the jig. It provides a door hinge coupling structure.

Hereinafter, a door hinge coupling structure using a square pin for position fixing according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a perspective view showing a door hinge is mounted with a square pin for position fixing according to an embodiment of the present invention, Figure 5 is a front view showing the front view of Figure 4, Figure 6 is a BB portion of Figure 5 It is sectional drawing which shows a cross section figure, and FIG. 7 is a perspective view which shows the square pin for position fixing.

As shown in the figure, the door hinge 10 supporting the door (not shown) to be opened and closed includes a first door hinge 110 fixed to the outer side panel side of the vehicle body via a fixing bolt 150. The second door hinge 120 is rotatably coupled to the first door hinge 110 and the rotation shaft 130 and fixed to the door side.

The structure of coupling the first door hinge 110 on the outer side panel, as shown in Figure 6, the high of the first door hinge 110 is attached to the outer side panel via a fixing bolt 150 Two first through holes 112 into which the fixing bolt 150 is inserted are formed on the government part 116, and a square pin 140 is inserted between the first through holes 112 to serve as a jig. The second through hole 114 to be fixed is formed.

As shown in FIG. 7, the square pin 140 has a cylindrical fastening portion 142 formed at one side of the square pin 140 formed in a square pillar shape and inserted into and fixed to the second through hole 114. At the end of the fastening portion 142 is formed a disc-shaped release prevention jaw 144 to prevent the separation, the other side is formed with an inclined portion 146.

The door hinge coupling structure using the square pin for position fixing according to the embodiment of the present invention having the configuration as described above maintains the size of the first through hole 112 formed in the first door hinge 110 as it is. While securing the assembly margin, it is possible to suppress assembly scattering such as unevenness of the parting gap and change of the sealing gap due to the gap formed between the fixing bolt 150 and the first through hole 112.

The present invention having the configuration described above can improve the assembly quality of the vehicle door by preventing the assembly scattering due to the gap formed between the fixing bolt and the first through hole, and by the uniformity of the sealing gap noise caused by the running wind Blocking the flow into the room has the effect of improving the quietness of the room.
