DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door mounting structure. More particularly, the present invention relates to a door hinge for mounting a back door of a vehicle.

[0002]

2. Description of the Related Art Generally, an automobile having a back door is of the type shown in FIG. In the figure, a is a door hinge connecting the back door b and the side body c.
FIG. 7 is a cross-sectional view taken along line VII-VII.

[0003] A side body c having a closed cross section is disposed on the side of the vehicle, and a back door b having a closed cross section formed by joining an inner panel d and an outer panel e is disposed at the rear of the vehicle. The door hinge a connects the side body c and the back door b to open and close the back door b. The door hinge a is bolted to the side f of the vehicle body inside the side body c and the side g of the back door b respectively.
It is concluded using. FIG. 8 shows an enlarged perspective view of the door hinge a. Two plate members j and k each having a substantially V-shaped cross section and having three bolt insertion holes i are opposed to each other, and one end thereof is connected to the other end, and the opening / closing is performed based on the connection l. I'm free.

A method for attaching the door hinge a to the vehicle body will be described with reference to FIG. First, door hinge a
Is fastened to the side surface g of the back door b using a bolt h. Next, the back door b is fully opened and the operator holds the back door b, and in this state, as shown in the drawing, the bolt h is pulled in the vehicle width direction using the tightening tool m to the side f of the side body c. To be fastened. At this time, as shown in FIG. 10, referred to as parting width, such that a gap L ₁ between the end portion o of the end n and side body c of the back door b is uniform over the entire circumference of the back door b In some cases, a spacer p may be interposed between the door hinge a and the side body c.

[0005]

However, the above-mentioned conventional vehicle door mounting structure has the following problems. (1) When the door hinge a is attached to the side body c, the back door b has to be fully opened. For this reason, since the worker holds the back door b, the man-hours for the mounting operation are large. (2) When the back door b is fully opened, the door hinge mounting portion on the side body side is exposed, so that a special cover must be attached. (3) Since the direction in which the door hinge a is bolted to the vehicle body side is substantially from the vehicle width direction, a spacer p is required when adjusting the width of the door only in the left-right direction.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a door mounting structure for an automobile which requires a small number of mounting steps, does not require a cover dedicated to a door hinge, and does not use a spacer for adjusting the width of a cut. .

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned object, and the gist of the invention is to make two convex plate-shaped members bent in a substantially rectangular shape in the same direction so that they have the same direction. A door hinge having a closed cross-sectional shape formed by joining the door inner and the door outer, and a side body disposed on the side of the vehicle. Is fixed to the door panel, the other plate is fixed to the rear end face of the side body from the rear of the vehicle, and the door hinge attachment portion is covered with a tail lamp or a rear bumper.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a door mounting structure for an automobile according to the present invention. FIG. 1 shows an automobile having a door mounting structure according to the present invention. FIG. 1 is a perspective view of the automobile 1 as viewed from the rear. The vehicle 1 has a side body 2 on a side of the vehicle, a tail lamp 3 provided on an upper portion of a rear end of the vehicle, and a rear bumper 4 provided on a lower portion. I have. A door hinge 5 is provided on the side of the tail lamp 3 and the rear bumper 4.

FIG. 2 is a cross-sectional view taken along the line II-II of FIG. One plate member 8 of the door hinge 5 is fixed to the side surface 7 of the back door 6 disposed at the rear of the vehicle. Further, the other plate member 10 of the door hinge 5 is fixed to the vehicle rear end surface 9 of the side body portion 2 disposed on the side of the vehicle, and the tail lamp 3 is attached from outside the door hinge 5. FIG. 3 is an enlarged perspective view of the door hinge 5. The two substantially plate-shaped plates 8 and 10 each have a bolt insertion hole 11, and an end of one plate 8 is connected to an end of the other plate 10. It has the structure of The door hinges 5 are connected to each other in a state where the convex sides of the plate members 8 and 10 are in the same direction. A method of attaching the door hinge 5 to the vehicle body will be described with reference to FIG.

With one plate member 8 of the door hinge 5 attached to the side surface 7 of the back door 6, the other plate member 10 is pressed against the rear end surface 9 of the side body 2. Next, the bolt 14 is fastened to the rear end face 9 with the fastening tool 13 facing the front of the vehicle. This fastening direction is orthogonal to the conventional fastening direction to the side body portion 2. For this reason, the back door 6
The back door 6 can be assembled to the vehicle body in a state where is closed. The tail lamp 3 is mounted on the vehicle body side using four to six screws at the upper part of the rear end of the vehicle, and the rear bumper is mounted on the vehicle body side using eight to ten screws at the lower part of the rear end of the vehicle. Normally, the door hinge 5 is attached to one door at two upper and lower positions. Since the upper door hinge is covered with the tail lamp 3 and the lower door hinge is covered with the rear bumper 4, a special cover for hiding the conventional hinge is not required. Then, after attaching the back door 6 to the side body portion 2 in a sheet metal process before painting the vehicle body, the tail lamp 3 and the rear bumper 4 are installed on the vehicle body in an outfitting process after painting the vehicle body.

Further, the bolt insertion hole 11 of the door hinge 5
Is slightly larger than the diameter of the bolt 14, and there is play. For this reason, as shown in FIG. 5, the back door 6 is slightly moved in the vehicle width direction, and the fixing position of the other plate member 10 of the door hinge 5 is shifted, so that the back door 6 and the tail lamp 3 or the vehicle body have a cut-off width L. ₂ can be easily adjusted. Also,
The back door 6 can be slightly moved in the front-rear direction and the up-down direction of the vehicle to adjust the clearance between the back door 6 and the vehicle body.

Other Embodiments The shape of the door hinge 5 is not limited to the above-described substantially V-shape. For example, approximately L, which is obtained by bending the plate members 8 and 10 at right angles,
It may be in the shape of a letter.

[0013]

As described above, according to the vehicle door mounting structure of the present invention, (1) the work of assembling the back door to the vehicle body and adjusting the width of the cut-out can be performed with the back door closed. .
For this reason, the number of work steps can be reduced, and the labor for holding the back door can be omitted. (2) A spacer is not required when adjusting the width of the back door and the vehicle body. (3) The exclusive cover for hiding the door hinge can be eliminated.
