DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a door hinge of an automobile, and more particularly, to the improvement of the positional relationship between a fulcrum position of a hinge between a door and a vehicle body, a mounting position of a weather strip, and a wiring position of a wire harness. It is intended to simplify waterproofing measures.

[0002]

2. Description of the Related Art In a door hinge portion which connects a vehicle body side and a door side of an automobile so as to be freely opened and closed, a door harness is routed from the door side to the vehicle body side, and an instrument panel harness (hereinafter referred to as an instrument panel) is provided on the vehicle body side. Harness), or the instrument panel harness is routed from the vehicle body side to the door side, and is connected to the door harness on the door side. Conventionally, the wire harness routed to this door hinge portion is routed at a position substantially the same as the hinge fulcrum position and changed in the vertical direction, and only twisting occurs in the wire harness with opening and closing of the door. Thus, the wire harness does not need to expand and contract, and the twist is absorbed by twisting the wire harness.

When the wire harness is routed at the hinge fulcrum position as described above, as shown in FIGS.
The hinge H between the vehicle body side C and the door D is the end face 1a of the door panel 1.
Door harness W / H
Needs to be taken out of the door through the inside of the door panel 1 and through the through hole 1b formed in the end face 1a, and it takes time and effort to route the wire harness inside the door panel 1 and pass through the through hole 1b. there were.

[0004] A weather strip 2 is attached to the door D for waterproofing. Since the weather strip 2 is attached to the indoor side of the hinge H, the wire harness W / H is also attached to the weather strip. 2
It is more outdoor. Therefore, the location where the wire harness W / H is routed cannot be waterproofed by the weather strip 2, so that a waterproof structure is required. Therefore, conventionally, it is necessary to attach the waterproof grommet G to the penetrating position on the door side and the vehicle body side, and also to provide a waterproof measure for the wire harness W / H, which increases the cost and increases the trouble. Was.

[0005] For example, FIG. 5 (A) and FIG.
In the structure for taking out and fixing the end portion of the door wire harness proposed in Japanese Patent Application Publication No. 2-54849, a work hole is provided from the door inner plate to the door end surface in order to eliminate the wiring harness routing work through a through hole provided in the door end surface. 5, a substantially L-shaped fitting 6 to be fitted into the work hole is provided, and a wire harness W / H is passed through a through hole 6a of the fitting 6 to form a through hole 6a.
Is stopped by a grommet 7 attached to a wire harness.

[0006]

With the above structure,
Although the workability is improved by passing the wire harness through the work hole 5 rather than passing the wire harness through the through hole provided in the door end surface, if the adhesion between the fixture 6 and the door is not sufficient, the weather strip 2 Because it is located more outdoor,
Inundation can occur. In addition, there are problems that a large number of parts such as the mounting fixture 6, screws 7 for fixing the mounting fixture 6 to the door, the cover 8, the grommet 7, and the like are required, and that assembling is troublesome.

[0007] It is an object of the present invention to solve the above-mentioned problems, and to achieve waterproofing even when the wire harness insertion portions on the door side and the vehicle body side have a non-waterproof structure.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a door hinge portion of an automobile, wherein the door is located outside a mounting position of a hinge connecting the vehicle body and the door. A weather strip is attached to the inner surface on the distal end side of the door, and a curved inward extending portion where the weather strip slides when the door is opened and closed is provided on a fender panel facing the front end side of the door. There is provided a structure of a door hinge portion of an automobile, wherein a wire harness is routed in a vertically phased position near a hinge position.

No grommet is attached to the wire harness routed between the door and the vehicle body. In addition, the wire harness is routed along the inner plate of the door, and the wire harness is routed from the door side to the vehicle body through an opening cut out from an end surface of the door inner plate.

[0010] As described above, since the weather strip is attached to the outdoor side of the hinge fulcrum and the wiring harness wiring position and is always in contact with the fender panel including opening and closing, the water strip is flooded at the wiring harness wiring position. Does not occur, so that the wiring harness wiring location can be made to have a simple waterproof or non-waterproof structure. In addition, even if an opening for inserting a wire harness with a large area is provided from the door inner plate to the end surface in order to enhance the wiring workability of the wiring harness, it is not essential to provide a waterproof closing means in the opening. No.

Furthermore, since the weather strip is conventionally attached to the door end surface closer to the room than the wire harness, even if the door harness is routed along the inner surface of the panel inner plate, the weather strip is arranged from the inner surface to the center of the end surface. The weather strip is located at the position where the cable is to be searched. Therefore, in order to avoid a weather strip, it is necessary to take out the door harness through the inside of the door, take it out from substantially the center of the door end face, and route it to the vehicle body. On the other hand, in the present invention, since the weather strip is located outside the wiring harness, the door harness can be routed along the inner surface of the door panel, and can be routed to the door end surface side. The wiring work of the harness becomes easy.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, a bracket 11 is provided on a surface of the door D facing the vehicle body C from an end surface 10a of the door inner panel panel 10 on the vehicle body side. An arm 13 is protruded, and the tip of the arm 13 is rotatably attached to the bracket 11 with a pin 14.
The hinge H is formed. The door D opens and closes by rotating with the pin 14 as a fulcrum.

The weather strip 15 is attached along the inner surface of the door tip outside the hinge fulcrum, which is the attachment position of the pin 14 of the hinge H. That is, as shown in FIG. 2, a weather strip receiving portion 16a is provided in which the front end of the door outer panel 16 is bent toward the interior side of the room and curved into a dish shape, and the receiving portion 16a has the shape shown in the drawing. The weather strip 15 is fitted inside.

The weather strip 15 is made of rubber as in the prior art, and has a hollow portion 15a provided therein so as to be easily bent, and is attached to the receiving portion 16a.
b protrudes forward from the front end of the door.

In front of the door D, a fender panel 17 is located outside the door facing the door panel panel 16, while the pillar 12 is located inside the room. The fender panel 17 is extended to the pillar 12 side than before. The extending portion 17a is opposed to the rotation trajectory of the door so that the distal end portion 15b of the weather strip 15 is in pressure contact with the extending portion 17a, and is also in sliding contact with the door D when the door D is opened and closed. It is curved in an arc shape.

On the other hand, the door harness D · W / H that is routed from the door side to the vehicle body side is provided on the inner surface 10 of the door inner panel panel 10.
b along the inner surface 10b from the front end to the end surface 10a.
Through the opening 10c which is notched to the side, it is drawn toward the vehicle body C from a vertically phased position on a substantially same vertical line as the hinge fulcrum H. On the vehicle body side, the cable is routed inside the vehicle body through a through hole 20a provided in the door side end surface 20.

[0018] The door harness D ·
The W / H is located closer to the indoor side than the weather strip 15, and the weather strip 15 is always in pressure contact with the fender panel 17 even during opening and closing operations to achieve waterproofing. No waterproof measures are taken. That is, although the grommet is conventionally attached to the door harness, the grommet is not attached in the present invention, and the opening 10c for harness insertion on the door side is not provided with water sealing means. In order to further attach a trim (not shown) to the door inner panel 10, an opening 10 is provided.
c is closed.

In the door hinge portion having the above-described structure, the weather strip 15 is attached to the outside of the wiring harness in a position outside the wiring harness, and the weather strip 15 is attached to the extending portion 17a of the fender panel 17 during opening and closing operations. Because it is always in pressure contact with the weatherstrip, even if rainwater from the outside tries to flood into the room, the weather strip 15
Is shut off by Therefore, since it is difficult for rainwater to enter into the opening 10c for inserting the wire harness of the door D and the through hole 20a on the vehicle body C side from outside, it is not necessary to attach a grommet to the wire harness to take waterproof measures.

[0020]

As is apparent from the above description, in the present invention, the position of the weather strip is changed to the outdoor side, and the wire harness is positioned on the indoor side of the weather strip. There is no need to take waterproof measures for the insertion part.

Further, after the wire harness is routed along the inner surface of the door inner plate, the wire harness can be pulled out from substantially the center of the door end surface toward the vehicle body without being interfered by the weather strip. As a result, it is not necessary to pass the wire harness through the through hole in the door end face, which is the most troublesome work, since it is not necessary to pass the wire harness through the center of the door end face once.
