DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring harness arranging structure in a door hinge portion of an automobile, and more particularly to a wiring harness arranging a wiring harness inside a weather strip on a room side from a hinge fulcrum. This facilitates simplification and simplification of waterproofing measures.

[0002]

2. Description of the Related Art A door hinge is connected to a vehicle body side from the door side to open / close a vehicle body side and a door side of an automobile, 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, the hinge H of the vehicle body side C and the door D is located substantially at the center of the end surface 1a of the door panel 1, as shown in FIGS. 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,
There is a problem that it takes time and effort to route the wire harness inside the door panel 1 and to pass it through the through hole 1b.

[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] The above-mentioned problem can be solved by disposing the wire harness W / H on the indoor side of the weather strip 2, but in this case, the position of the hinge fulcrum and the wiring position of the wire harness W / H are required. Therefore, it is necessary to expand and contract the wire harness W / H when the door is opened and closed. That is,
The wire harness routed to the door hinge is required to have both the function of expanding and contracting and the function of absorbing torsion.

[0006] Japanese Unexamined Patent Publication No. 8-48 discloses a structure in which a wire harness is routed on the indoor side of the weather strip.
No. 146. That is, as shown in FIGS. 18 and 19, a bellows-shaped duct 4 for covering the air-conditioning duct is attached between the side cover 3 of the instrument panel and the door inner surface 1c opposed thereto.
The wire harness W / H is spirally wound inside and is provided with a margin.

[0007]

However, in the above structure, since the bellows-like wire harness W / H is routed inside the bellows-like duct 4, the following problems occur.

FIG. 20A shows a wiring harness W / H.
As shown in (B), when passing through the center position inside the bellows-like duct, both the bellows-like duct 4 and the bellows-like wire harness W / H can expand and contract in a normal state. However, as shown in FIG.
When a portion W of / H enters the concave portion 4a of the bellows portion of the duct 4, the duct 4 cannot be contracted. In this state, FIG.
When the door D is closed as shown in (B), the duct 4 and the wire harness W / H are damaged by the door panel 1 and the side cover 3 and the electric wires may be disconnected.

When the bellows-like wire harness W / H expands and contracts, it does not always restore to a constant shape. If the outer diameter of the wire harness becomes larger than the inner diameter of the bellows-like duct 4, the bellows-like duct becomes It is destroyed and cannot shrink.

Since the bellows-shaped duct 4 is exposed to the indoor side, there is a possibility that the bellows-shaped duct 4 is deformed by an external force.
And the above problem is likely to occur.

When the door is opened and closed, an operation force for expanding and contracting the bellows-shaped duct 4 is required in addition to the force for opening and closing the door, which causes a problem that the occupant feels that the opening and closing of the door is heavy.

The present invention solves the above-mentioned problems, and arranges and arranges a wiring harness having both a twist absorbing function and a telescopic function at a position indoors from a hinge fulcrum and inside a weather strip. It is an object of the present invention to facilitate work and simplify waterproofing measures.

[0013]

In order to solve the above-mentioned problems, according to the present invention, a wire harness routed between a vehicle body and a door is attached to a hinge mounting position connecting the vehicle body and the door. A thin guide frame which is opened at a position apart from the wire harness insertion opening and the outlet, and the wire harness is fixed to the insertion opening of the guide frame. The wire harness inside the guide frame is accommodated so as to be drawn out from the outlet while being diverted inside the guide frame, and the wire harness inside the guide frame is passed through a regulating cylinder having both ends opened. The guide frame is fixed to either the door or the vehicle body, and the tip of the wire harness drawn out from the outlet of the guide frame is fixed to the door. Or a wiring harness in a door hinge portion of an automobile, wherein the wiring harness extends and extends to one of the other sides of the vehicle body, and the wiring harness is adapted to protrude and retract from the guide frame according to the opening and closing operation of the door. Provides routing structure.

When the door is opened, the wire harness can be pulled out from the guide member and made to follow the door frame when the wire harness is accommodated in the guide frame so as to be detoured, not linearly, from the insertion opening to the outlet. When the door is closed, the elongated wire harness is inserted into the guide member from the outlet. Further, the twist at the time of opening and closing the door can be followed by twisting of the wire harness itself pulled out from the guide member. Further, the present invention provides, in claim 2,
A wiring harness routed between the vehicle body and the door is routed indoors from a mounting position of a hinge connecting the vehicle body and the door and a weather strip, and the wire harness insertion port and the outlet port are connected to each other. A thin guide frame is opened at a remote position, a wire harness is fixedly inserted into an insertion opening of the guide frame, and the wire harness is accommodated so that the wire harness is drawn out from the outlet through a detour inside the guide frame. ,
A configuration in which the guide frames are fixed to the door and the vehicle body, respectively, and the wire harnesses drawn out from the outlets of both the guide frames are made continuous, and the wire harness can follow and follow the guide frames in accordance with the opening and closing operation of the door. The present invention provides a wiring harness wiring structure in a door hinge of an automobile.

That is, in the first aspect, the guide frame is attached to either the door side or the vehicle body side.
As described in claim 2, the wire harness is attached to both the door side and the vehicle body side, and when the door is opened, the wire harness is pulled out from both guide frames, while when the door is closed, the wire harness is drawn into both the guide frames. .

The guide frame has a substantially triangular shape, the insertion port is provided at a first vertex and the outlet is provided at a second vertex, and the wire harness is detoured to the third vertex side to be inserted into the guide frame. It is preferable that it is accommodated. (Claim 3) That is, although the shape of the guide frame is not limited, if the shape is substantially triangular as described above, the wire harness is detoured along the inner peripheral surface inside the guide frame with a simple shape. be able to.

The guide frame is vertically accommodated and fixed in a concave portion formed in a door end surface, an inner surface inside a door room, a vehicle body end surface facing the door end surface, or a door end surface of an instrument panel. (Claim 4) When housed in the vertical direction as described above, the housing width can be reduced, and it can be easily attached to a door having a small installation space.
Therefore, when attaching the guide frame to the instrument panel or the vehicle body having a relatively large installation space, the guide frame may be fixed in the horizontal direction. In short, the direction in which the guide frame is installed is not limited, as long as it can be accommodated in the guide frame as much as it is pulled out when the door is opened.

The guide frame is formed in a back opening or a thin box shape, and has a locking claw that is removably locked in a locking groove provided in a door or a vehicle body. Alternatively, while the wire harness is slidably housed between the inner surface of the vehicle body and the box-shaped guide frame, the wire harness is slidably housed therein. (Claim 5) Since the space occupied by the guide frame is preferably as small as possible, the wire harness is slidably sandwiched between the door or the vehicle body and the guide frame. In addition, if the locking claw is provided as described above and locked with the locking claw on the door side or the vehicle body side, the guide frame can be attached with one touch. When the guide frame has a box shape, the width of the hollow portion is set slightly larger than the outer diameter of the wire harness so that the wire harness does not overlap inside the guide frame.

It is preferable that a cylindrical portion protrudes from the insertion opening and the outlet of the guide frame, and the cylindrical portion of the insertion opening and the wire harness be fixed by tape winding. (Claim 6) That is, since the insertion opening and the outlet of the wire harness need to be regulated to a fixed position, the wiring harness is formed into a cylindrical shape through which the wire harness is inserted, and the wire harness is fixed to the cylindrical portion with tape on the insertion opening side. are doing. By protruding the cylindrical portion in this manner, it is easy to fix with a tape.

As described above, according to the present invention, the wire harness is passed through the regulating cylinder having openings at both ends, and the regulating cylinder is slidably disposed inside the guide frame at a position continuous with the outlet. When the wire harness is passed through the regulating cylinder inside the guide frame in this way, when the wire harness is retracted from the outlet into the guide frame when the door is closed, it can be reliably pulled through the regulating cylinder.

A wire harness is tightly fitted into the regulating cylinder so as to interlock with the regulating cylinder, and a spring is stretched between the regulating cylinder and the guide frame to pull the wire harness into the guide frame. Preferably, it is energized. (Claim 7) If the regulating cylinder is urged in the retracting direction by the spring, the wire harness can be retracted faster than the door closing speed when the door is closed.

It is preferable that the wire harness, which is drawn out between the door and the vehicle body through the guide frame, is covered with a rigid tube or the like. Also, a rubber mounting member is attached to the tip of the wire harness that is pulled out from the guide frame and mounted on the vehicle body side or the door side, so that the wire harness is also torsionally absorbed at the rubber mounting member. Is also good.

While the guide frame is fixed to the door side, the wire harness passing through the guide frame may be routed by inserting the distal end of the wire harness through an opening formed in the door-side end surface or the door-side lower surface of the instrument panel. (Claim 8)

As is apparent from the above description, in the wiring harness wiring structure in the door hinge portion of the automobile according to the present invention, the wiring harness is wired not at the same position as the hinge position but at the inside position on the indoor side. Therefore, when the door is opened and closed, the wire harness is required to have both the expansion and contraction function and the twist function. However, since these guide frames are provided and the wire harness is attached to the guide frame, the wire harness is expanded and contracted when the door is opened and closed. In addition, since the wire harness itself pulled out from the guide frame is twisted, it can be smoothly followed while expanding and contracting and twisting in conjunction with the opening and closing operation of the door.

Further, since the guide frame has a thin and small frame shape or a thin box shape enough to insert a wire harness, it can be attached to a small space between a door and / or a vehicle body. Moreover, by installing the trim after the installation, the trim is not exposed to the indoor side, and the appearance is not impaired. Furthermore, since the guide frame is small and lightweight, the mounting force of the door does not increase and the opening and closing of the door does not become heavy by attaching the guide frame.

Further, since the wire harness is routed inside the hinge position and inside the weather strip, it is not necessary to take waterproofing measures for the wire harness, and the conventionally used grommet and the like can be used. Can be eliminated. Further, the wire harness can be routed to the inner side of the door panel, so that the wire harness that is conventionally required inside the door panel is routed, and the work of removing the wire harness from the through hole provided in the front surface of the door panel is eliminated. Therefore, the work of arranging the wire harness on the door panel can be made much easier as compared with the related art.
