Description

  The present invention relates to a wire harness routing structure that is routed from a vehicle body to a slide door.

Conventionally, electrical components such as a power window are mounted on the sliding door of an automobile, and a wire harness is routed between the vehicle body and the sliding door to constantly supply power to the electrical components from the vehicle body side. .
A wiring harness wiring structure of this type is provided in Japanese Patent Laid-Open No. 2000-264136 (Patent Document 1). In the wiring structure of the wire harness provided in Patent Document 1, as shown in FIG. 8, the slide block 3 is slidable on the guide rail 2 that is attached to the lower position of the slide door 1 and extends in the longitudinal direction of the vehicle body. A wire harness that is attached to the slide block 3 and that spans the connecting portion 4a on the distal end side from the fixed position of the wire harness 4 fixed to the slide block 3 to the vehicle body side, and the connector 5 connected to the terminal is routed to the vehicle body side. It is connected to a connector (not shown).

When the slide door 1 is opened and closed, the slide block 3 slides in the front-rear direction along the guide rail 2, and the wire harness 4 follows the opening and closing of the slide door 1.
That is, when the slide door 1 is operated from the fully closed state shown in FIG. 9A to the fully opened state shown in FIG. 9B, the slide block 3 moves forward along the guide rail 2 and slides in the fully open state. The block 3 is disposed at the front end position of the slide door 1. Therefore, when the slide door 1 is in the fully open state, as shown in FIG. 9C, the crossover portion 4a of the wire harness 4 extends from the front end of the slide door 1 to the rear end of the opening portion 6a serving as the entrance / exit of the vehicle body 6. Will be searched.
With the above configuration, since the crossover portion 4a of the wire harness is routed at the lower position, the crossover portion 4a is arranged at the feet of the passengers getting on and off, and the passengers step on the crossover portion 4a, There is a risk of causing damage to the wire harness 4 when dropped.
Moreover, since the transition part 4a of the wire harness 4 is exposed to the lower position where the opening part 6a is easily visible when the slide door 1 is opened, there is a problem that is not preferable in appearance.

JP 2000-264136 A

  The present invention has been made in view of the above problems, and changes the wiring position of a wire harness that is routed between a vehicle body and a sliding door so that the wire harness is generated by a stepping by an occupant or an impact of a fallen object. It is an object to prevent the damage of the wire harness and to improve the appearance by making the wire harness less visible from the outside when the sliding door is opened.

In order to solve the above-mentioned problems, the present invention provides a guide rail mounted on the vehicle body side that supports a support member projecting from a lower end, an upper end of the slide door and a central portion in the vertical direction so that the support member can move freely when the door is opened and closed. The center rail of the upper part or the upper rail on the upper end side is used as a guide member for a wire harness for power feeding that runs from the vehicle body side to the sliding door side,
The wire harness is fixed to the support member protruding from the slide door, and the wire harness is moved in conjunction with the support member that moves the guide rail according to the opening / closing operation of the slide door. The wire harness wiring structure to the sliding door is provided.

According to the wiring structure of the wire harness to the slide door having the above-described configuration, the center rail in the vertical direction supporting the slide door or the upper rail on the upper end side is used as the guide member of the wire harness. The connecting part of the wire harness that runs between the two is routed to the center or the upper end side in the vertical direction and is not exposed to the lower end side of the passenger's doorway. As a result, the wire harness is not exposed at the feet that are easily visible to the occupant, so that the appearance can be improved, and damage to the wire harness due to the stepping by the occupant, dropping of luggage, and the like can be prevented.
In addition, since the guide rail attached to the vehicle body is used as a guide member for the wire harness, and the wire harness is fixed to the support member to follow the operation of the slide door, the wire harness follows the slide door as in the conventional example. It is not necessary to provide a new structure for making it happen.

In particular, after routing the wire harness along one of the upper and lower surfaces of the center rail that slidably fits and holds the roller of the support member, the center rail as a guide member of the wire harness, It is bent in a U shape and placed vertically, and the tip of the bent side is fixed on the vehicle body side,
It is preferable that the vertically placed wire harness is accommodated in a gap between a vehicle body panel having the center rail fixed to the outer surface and a cover panel attached to the outer surface side of the vehicle body panel.

As described above, when the center rail is used as the guide member of the wire harness, when the sliding door is opened, the support member fixed to the sliding door moves rearward along the center rail, and when the center rail is fully opened, Arranged at the rear end position. That is, when the sliding door is fully opened, the support member is disposed at a rear position far away from the passenger's doorway,
The crossover portion of the wire harness fixed to the support member is also moved backward in conjunction with the passenger's doorway. Therefore, the crossover of the wire harness that spans between the sliding door and the vehicle body is not exposed at the lower end of the passenger's entrance and exit, and is placed in a space that cannot be easily seen between the center rail and the sliding door. Can be good.
Furthermore, when the center rail is used as a guide member, the wire harness to be routed can be arranged in the gap between the vehicle body panel and the cover panel on the vehicle body side, and the wire harness is bent vertically and placed vertically. If it arrange | positions, the narrow clearance gap between the said panels can be utilized as a sliding space of a wire harness.

  A harness guide case for inserting the wire harness bent in the U-shape is provided, and the harness guide case is fixed along the entire upper surface of the upper wall of the center rail or the entire lower surface of the lower wall, and the center of the harness guide case A door side portion of the wire harness having an end portion fixed to the support member is disposed along the inner surface of the rail side fixed wall, and the vehicle body side is disposed along the inner surface of the wall facing the center rail side fixed wall vertically. A side portion of the vehicle body of the wire harness having an end portion fixed thereto is disposed.

The center rail is attached to the outer surface of the vehicle body panel for the rear side of the vehicle body from the fully closed slide door and extends horizontally, and the front end side of the slide door is curved inward. Accordingly, the harness guide case fixed to the center rail over its entire length is curved inward on the front end side along the shape of the center rail.
The harness guide case is made of resin and has a U-shaped vertical cross section, and both front and rear ends are open, and a U-shaped bent portion of the wire harness can protrude from the front end opening when the slide door is fully closed.
The harness guide case is relatively large in the vertical direction so that the harness guide case can be placed vertically between the body panel and the cover panel of the vehicle body, and the protruding amount of the upper and lower walls protruding toward the cover panel is reduced. The width of the fixed wall of the harness guide case fixed to one of the upper and lower walls is matched.
The harness guide case may have a box shape without opening the outer surface side, but the outer surface side may be opened because it is closed by the cover panel of the vehicle body.
In this way, when the wire harness is bent in a U shape in advance and inserted into the harness guide case, the wire harness can be protected and the generation of abnormal noise can be prevented without interfering with the vehicle body panel. The workability of attaching the wire harness to the side can be improved.
It is preferable that a tube is sheathed on the wire harness and inserted through the harness guide case.

Without using the harness guide case described above, the wire harness bent in a U shape is slidably held in the gap between the vehicle body panel and the cover panel,
A tube may be externally fitted to the wire harness, and / or a protective sheet may be attached to the contact surface side of the body harness and the wire harness of the cover panel.

That is, if the gap between the vehicle body panel and the cover panel of the vehicle body is narrow and the wire harness routed in the gap can be slidably held between the vehicle body panel and the cover panel, the harness guide case described above is not used. The vehicle body panel and the outer panel can be used as opposing walls of the guide case of the wire harness.
In this case, since the wire harness is slidably contacted with the vehicle body panel or the cover panel, wear is likely to occur. Therefore, the wire harness is covered with a corrugated tube or the like that has wear resistance and has a soft surface that is unlikely to generate abnormal noise when sliding. It is preferable.
Further, a protective material such as sponge may be attached to the sliding surface of the vehicle body panel and the cover panel.
Thus, if the harness guide case is not required, the cost can be reduced by reducing the number of parts.

  The support member projecting from the slide door is a wire harness that fixes the wire harness to a bracket projecting a roller that is fixed to the slide door and slidably fitted and held on the center rail via a clamp. A fixing portion is projected, and a horizontal piece provided on the wire harness fixing portion is slidably placed on the guide rail or the upper or lower surface of the harness guide case fixed to the guide rail. .

According to the above configuration, the horizontal piece of the wire harness fixing portion is placed on either the guide rail or the horizontal upper and lower walls of the harness guide case so as to be placed in a stable state. The movement of the support member accompanying the opening and closing can be surely followed.
The wire harness fixing portion may be provided integrally with the metal bracket, or may be provided separately from metal or resin, and fixed to the bracket and protruded.

Connectors are connected to both ends of the wire harness, and a door-side connector connected to the tip of a sliding door harness fixed inside the sliding door and a connector on the tip side from a fixing portion of the support member of the wire harness are connected. In addition, the connector on the other end side is preferably connected to the vehicle body side connector connected to the front end of the floor harness on the vehicle body side.
As described above, when the wire harness to be routed between the sliding door and the vehicle body is separated from the door side wire harness and the vehicle body side wire harness and is connected to the connector, the wire harness at the transition portion is inserted into the harness guide case. It can be modularized and the wiring workability of the wire harness can be improved.
The vehicle body side wire harness may be extended to the crossover portion and connected to the door side wire harness, or conversely, the door side wire harness may be extended to the crossover portion and connected to the vehicle body side wire harness. Good.

  The wire harness may be formed by converging round electric wires, or may be formed from a flat harness. If it is a flat harness, the accommodation space of the wire harness of a transition part can be made still thinner.

As described above, in the present invention, the guide rail of the slide door attached to the vehicle body side is used as the guide member of the wire harness that is routed between the vehicle body and the slide door, and the slide door moves along the guide rail. Since the wire harness is fixed to the support member protruding from the wire and the wire harness is moved along the guide rail in conjunction with the movement of the support member, the guide member in the crossover portion of the wire harness becomes unnecessary. At the same time, the wire harness can reliably follow the opening / closing operation of the sliding door.
In addition, as a guide rail to be used as a guide member for the wire harness, a wire harness that is routed from the slide door to the vehicle body side as a center rail or an upper rail is arranged at a position above the floor as a guide rail on the floor side. . Therefore, when the sliding door is opened, the wire harness is not exposed on the floor side, and it is possible to reliably prevent the wire harness from being damaged due to the stepping on the occupant or dropping of the luggage. And since it is not exposed to the lower end side of the entrance / exit which is easy to catch a passenger | crew, an external appearance can be made favorable.

  In particular, if a wire harness guide member is routed across a center rail fixed to the vehicle body panel on the side of the vehicle body, the center rail is fixed to the vehicle body panel and covered with a cover panel. The sandwiched gap can be effectively used as a sliding space for the wire harness.
