Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure of an automobile, and more particularly to a back door hinge attachment portion structure used for attaching a back door to a vehicle body so that the back door can be freely opened and closed.

[Conventional technology]

A back door that is openably and closably provided on a vehicle body is attached to a vehicle body panel such as a roof panel via a back door hinge. Conventionally, the structure of the back door hinge mounting portion has a structure as shown in FIG. 5 and FIG.
See 201717).

That is, the bolt 3 as a fixing member is fixed to the fixed arm 2a of the back door hinge 2 fixed to the upper end of the back door 1 by means of welding or the like. Then, the bolt 3 is inserted into the mounting hole 5 formed in the roof panel 4, the tool is inserted from the working hole 6 provided in the rear roof rail 4A, and the fixing nut 7 is fastened to the bolt 3 to fix the back door hinge 2. The side arm 2a is attached to the roof panel 4. Here, in order to adjust the construction of the back door 1, the diameter of the mounting hole 5 is made sufficiently larger (about 1 to 3 mm) than the outer diameter of the bolt 3, and when the back door 1 is assembled, the fixing nut 7 is attached. After adjusting the built-up state of the back door 1 in the state of loosening, the fixing nut 7 is completely fastened to the bolt 3.

[Problems to be solved by the invention]

By the way, in recent years, there is an increasing need to actually remove the back door from the vehicle body and drive the vehicle for the purpose of obtaining a feeling of openness or improving ventilation in the vehicle. However, in the conventional structure, a skilled worker adjusts the building in the manufacturing process to mount the back door, and therefore, when the user once removes the back door from the vehicle body, the manufacturing process is performed when the back door is mounted again. There is a structural problem that it is extremely difficult for the user to reproduce the built-up state adjusted by, and it was not possible to meet the above needs.

[Means for solving problems]

In order to solve such a problem, the present invention provides a back door hinge mounting part structure for mounting a back door on a vehicle body panel so that the back door can be opened and closed. On the hinge side bolt for fixing the spacer plate and the body panel side surface, there are provided bolt plates on which the vehicle body side bolts for fixing the spacer plate are respectively projectingly arranged at the adjusted positions of the vehicle body panel, the back door hinge and the body panel. The back door hinge is fixed by interposing between them, and a cap for hiding the bolt plate from the outside of the vehicle body is detachably provided on the hinge side of the bolt plate.

[Action]

According to such means, it is possible to set the bolt diameter on the vehicle body side and the diameter of the mounting hole of the vehicle body in consideration of the assembling error in the conventional manner at the time of adjusting the building, so that the ease of assembling is not impaired at all. . On the other hand, after the construction adjustment, the back door is installed between the bolts on the hinge side and the bolt holes on the back door, which does not significantly affect the molding accuracy of the parts and allows extremely accurate positioning of the parts. Since it can be attached and detached, it is possible to reproduce the same mounting state as when adjusting the building many times.

〔Example〕

Hereinafter, the present invention will be described based on examples. 1 and 2 are diagrams showing an embodiment of the present invention. The same parts as those in FIG. 5 will be described with the same reference numerals.

The fixed side arm 2a of the back door hinge 2 provided at the upper end of the back door 1 is provided with a bolt hole 2b through which the hinge side bolt 8b can pass. On the other hand, the roof panel 4 is reinforced by the roof rain force 10, and the mounting holes 4a and the mounting holes 10a whose central axes coincide with each other so that the vehicle body side bolt 8a can pass through the roof panel 4 and the roof rain force 10 respectively. Provided with Force 10. To fix the fixed arm 2a to the roof panel 4, a bolt plate 8 is used. The bolt plate 8 includes a spacer plate 8c and a hinge side bolt 8b on one surface thereof and a vehicle body side bolt on the other surface thereof.
8a is fixed by means such as welding. In this embodiment, the axis of the hinge side bolt 8b and the axis of the vehicle body side bolt 8a are aligned. Here, in order to achieve the object of the present invention,
The diameter of the bolt hole 2b provided in the fixed side arm 2a is smaller than the outer diameter of the hinge side bolt 8b by the dimensional tolerance (generally 0.1 to 0.3
mounting holes 4a, 10a provided on roof panel 4 and roof reinforcement 10 to adjust the building condition.
Is sufficiently larger than the outer diameter of the bolt 8a (1 mm or more)
Set. A working hole 6 for inserting a tool when tightening the nut 7a is provided on the lower surface of the rear roof rail 4A. Further, a cap 11 for concealing the bolt plate 8 and the like from the outside is mounted above the bolt plate 8.

When the back door 1 is attached to the vehicle body in the manufacturing process with the above configuration, first, the hinge side bolt 8b is inserted into the bolt hole 2b of the fixed side arm 2a and the nut 7b is fastened to fix the bolt plate 8. Attach to the side arm. Next, a synthetic rubber seal rubber 9 having a mounting hole 9a through which the bolt 8b penetrates is attached to the vehicle body side bolt 8a corresponding to the shape of the spacer plate 8c, and the mounting hole 4a of the roof panel 4 and the roof reinforcement 10 are mounted. Insert the bolt 8a into the mounting hole 10a and fasten the nut 7a. When performing this assembly work, the nut
After adjusting the backdoor 1 installation with 7a loosened,
The fixed arm 2a of the back door hinge 2 may be completely fixed to the roof panel 4 by tightening the nut 7a.

When the user removes or attaches the back door 1, the nut 7a on the inside of the vehicle body should not be touched by the user,
After removing 11, remove the nut 7b and backdoor hinge 2
If the bolt plate 8 is disassembled, the back door 1
When installing the hinge side bolt 8b and fixed side arm 2a
Since it is processed with high precision with the bolt hole 2b of
8b plays a role of positioning bolt 8b and fixed arm 2a.
By engaging with the bolt hole 2b, the installed state adjusted in the manufacturing process can be reproduced.

Next, another embodiment will be described with reference to FIGS. 3 and 4. In this embodiment, the bolt plate 8 according to the above-mentioned embodiment is used.
Instead of the above, a bolt plate 18 described below is provided.

That is, for example, two through bolts are used for each of the vehicle body side bolts 18a and the hinge side bolts 18b, which are fixing members, and the threaded portions of each through bolt are inserted into the through holes formed in the spacer plate 18c to insert the bolt heads. The spacer plate 18c is fixed by welding or the like so as to project. At that time, in the present embodiment, unlike the case of the above-described embodiment, the shaft center of the vehicle body side bolt 18a and the hinge side bolt 18b.
While avoiding overlapping of bolt heads by shifting the shaft center of the spacer plate 18c, the spacer plate 18c has a step formed by taking into account the thickness of the bolt head and recessing the portion closely contacting the bolt head. There is. Further, in the present embodiment, the seal rubber 19 is divided into two and used for the vehicle body side bolts 18a, respectively. The procedures for adjusting the building and removing and installing the back door 1 are the same as those in the above-described embodiment.

Further, in the above embodiments, the building adjustment is performed on the vehicle body side bolts, but the building adjustment may be performed on the hinge side bolts.

〔The invention's effect〕

As is clear from the above description, according to the present invention, even if the back door is attached to or detached from the vehicle body, the installed state of the back door adjusted in the manufacturing process can be reproduced, so that the user can easily perform the back door hinge. The effect is that a detachable back door that can be attached to and detached from can be configured.
