Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle door mounting structure in which a door is mounted on a vehicle body so as to be openable and closable.

[Conventional technology]

Some conventional door hinges for attaching a door to a vehicle body so as to be openable and closable have been proposed. For example, as shown in FIG. 4, it is disclosed in Japanese Utility Model Laid-Open No. 62-182369. The configuration includes a door side hinge bracket 1 attached to the door and a vehicle body side hinge bracket 2 attached to the vehicle body. In this configuration, the connecting portions 1a, 1b of the door side hinge bracket 1 are inserted between the connecting portions 2a, 2b of the vehicle body side hinge bracket 2, and the insertion portions provided in the respective connecting portions 1a, 1b, 2a, 2b are inserted. Hole 1c / 1d / 2c
The door side hinge bracket 1 and the vehicle body side hinge bracket 2 are rotatably coupled to each other by inserting the hinge pin 3 into 2d.

Generally, the door is attached using the door hinge as described above by assembling a pair of the door side hinge bracket 1 and the vehicle body side hinge bracket 2 up and down on the door and the vehicle body in advance, respectively. It is performed by connecting the connecting portions 1a and 1b and the connecting portions 2a and 2b with the hinge pin 3 in a state where the connecting portions 1a and 1b of the door side hinge bracket 1 are inserted between the two connecting portions 2a and 2b. There is.

[Problems to be solved by the device]

However, in the above-mentioned conventional door hinge, since the joining portions 1a and 1b of the door side hinge bracket 1 are inserted and joined between the joining portions 2a and 2b of the vehicle body side hinge bracket 2, it is difficult to position the insertion position. It becomes difficult to align the insertion holes 1c, 1d, 2c, 2d when inserting the hinge pin,
It took time to assemble both hinge brackets.

Further, generally, since the door hinges are provided at two upper and lower positions in the opening / closing portion of the door, if the intervals between the door side hinge brackets 1 and between the vehicle body side hinge brackets 2 are uneven, it is difficult to attach the door. Also, if there is a variation in the pitch between the joints 1a and 1b and between the joints 2a and 2b, it will be difficult to attach the door. Therefore, in order to eliminate the above variations, there has been a problem that dimensional control of parts and positional control of assembly must be strictly performed.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, a vehicle door mounting structure according to the present invention is mounted on a door and is vertically opposed.
And a door-side hinge bracket having a second coupling portion,
A vehicle body-side hinge bracket that is attached to a vehicle body and has third and fourth coupling portions that face each other vertically
The coupling portion, the third coupling portion, the second coupling portion, and the fourth coupling portion are arranged in this order, and are rotatably coupled around a coupling shaft that vertically penetrates through holes provided in these coupling portions. The door is attached to the vehicle body at two positions vertically separated from each other via the upper door hinge and the lower door hinge, and the upper door hinge is provided with a third and a third holes around the through holes in the lower end surfaces of the first and second coupling portions. A first tubular member is fixed which is inserted into the through hole of the fourth coupling portion and penetrates the coupling shaft therein.
A head provided at one end of the coupling shaft is locked to the lower end surface of the fourth coupling portion, and a screw portion provided at the other end of the coupling shaft is screwed into the through hole of the first coupling portion. The lower door hinge is inserted into the through holes of the first and second coupling parts around the through holes in the upper end surfaces of the third and fourth coupling parts, and the second tubular member that allows the coupling shaft to penetrate therethrough is fixed therein. And the head portion of the coupling shaft is locked to the upper end surface of the first coupling portion, and
The threaded portion of the coupling shaft is screwed into the through hole of the coupling portion.

[Action]

In the above configuration, when the door is attached to the vehicle body, the vehicle body-side hinge bracket and the door-side hinge bracket, which are in a separated state from each other before the attachment, are attached to the upper door hinge and the lower door hinge from the first connecting portion, the third connecting portion from the top. The joining portion, the second joining portion, and the fourth joining portion are arranged in this order.
Then, the door is lowered from above to insert the first tubular member into the through holes of the third and fourth coupling portions, and the second tubular member to the through holes of the first and second coupling portions. Insert it.

Then, in the upper door hinge, the coupling shaft is penetrated from the lower side through the through holes of the fourth coupling section, the second coupling section, the third coupling section, and the first coupling section via the first tubular member. Further, since the head portion of the coupling shaft is locked to the lower end surface of the fourth coupling portion and the screw portion of the coupling shaft is screwed into the through hole of the first coupling portion, the vehicle body side hinge bracket and the door side The hinge bracket is vertically constrained by the connecting shaft.

On the other hand, in the lower door hinge, the coupling shaft is penetrated from the upper side through the through holes of the first coupling portion, the third coupling portion, the second coupling portion, and the fourth coupling portion via the second tubular member. Further, since the head portion of the coupling shaft is locked to the upper end surface of the first coupling portion and the screw portion of the coupling shaft is screwed into the through hole of the fourth coupling portion, the vehicle body side hinge bracket and the door side The hinge bracket is vertically constrained by the connecting shaft.

In this way, the vehicle body side hinge bracket and the door side hinge bracket are constrained by the connecting shaft, so that the upper door hinge and the lower door hinge rotate about the connecting shaft.

Therefore, if the structure as described above is adopted, the vehicle body side hinge bracket and the door side hinge bracket are connected by one connecting shaft, and the number of parts and the number of working steps can be reduced. Moreover, since the heads of the connecting shafts are respectively locked to the lower end surface of the fourth connecting portion by the upper door hinges and the upper end surface of the first connecting portion by the lower door hinges, they are arranged at positions closest to each other. Will be done. Therefore,
The moving distance of the tool for tightening the coupling shaft can be minimized.

Further, since the threaded portion of the coupling shaft is screwed into the through hole of the first coupling portion at the upper door hinge and is screwed into the through hole of the fourth coupling portion at the lower door hinge, the first and second coupling portions are connected. Even if there is a variation in the spacing, the spacing between the third and fourth coupling portions, or the spacing between the door hinges, it is possible to reduce the influence of the variation by adjusting the tightening of the screw portion.

Furthermore, when the door-side hinge bracket is assembled to the vehicle-body-side hinge bracket, by inserting the tubular member into the through hole, it is possible to easily align the through holes in the first to fourth coupling portions, The assembling work can be facilitated. Moreover, since the first and second tubular members penetrate the coupling shaft in the through hole, they can also serve as bearings.
