Description

  The present invention relates to a mounting structure of a wire harness for feeding a sliding door, and more specifically, while preventing the interference with peripheral members by regulating the curved trajectory of the wire harness routed between the sliding door and the vehicle body, The wire harness smoothly follows the opening / closing operation of the sliding door.

2. Description of the Related Art Conventionally, a wire harness routed in a vehicle is protected with various exterior protective materials in order to prevent electric wire damage or disconnection due to interference with peripheral components. For example, in Japanese Patent Application Laid-Open No. 2004-25999 (Patent Document 1), as shown in FIG. 7, a wire harness W / H is inserted through a caterpillar-shaped cable guide 2 in which a plurality of link members 1 are linearly connected. A structure in which this is bridged in an S shape between the slide door 3 and the vehicle body 4 has been proposed.
By passing the wire harness W / H through the caterpillar-shaped cable guide 2, the trajectory of the wire harness W / H that is curved while following the movement of the slide door 3 is controlled, and the wire harness W / H and peripheral members are controlled. It is possible to prevent interference.

However, the caterpillar-shaped cable guide 2 is expensive and has a structure that spans an S-shape. Therefore, a long wire harness and a cable guide are required, resulting in a high cost.
Further, since the wire harness W / H inserted through the cable guide 2 is exposed from the gap between the link members 1, it is necessary to further prevent the exposure by covering the cable guide 2 with the tube body 5 as shown in FIG. There is a problem that the number of parts and work man-hours increase and the cost further increases.
Furthermore, some slide doors 3 operate while changing the angle in the vertical direction. In order to cope with such vertical movement, a vertical movable mechanism as shown in FIG. 9 is further provided. It is necessary [Japanese Patent Laid-Open No. 2004-40862 (Patent Document 2)]. That is, it is necessary to interpose the connecting member 7 pivotally supported in the vertical direction (arrow T direction) between the support member 6 fixed to the vehicle body 4 and one end portion of the cable guide 2. There is a problem that the number of points further increases and the structure becomes complicated.
Further, when the slide door 3 is fully opened, the cable guide 2 sheathed on the wire harness W / H is stretched in an S shape and swells in the vehicle width direction, and the distance between the slide door and the vehicle body when fully opened is In a small vehicle, since the cable guide 2 may interfere with a tire or a tire house, the cable guide 2 may not be used as an exterior protective material.

  On the other hand, when a configuration such as a tube-shaped exterior protective material that does not use the cable guide 2 as described above is used, even if a smooth bending operation is possible, the wire harness or the tube itself may hang down due to the weight of the wire harness or the wire harness. However, there is a problem that the wire harness easily interferes with the peripheral members and is damaged.

JP 2004-25999 A JP 2004-40862 A

  The present invention has been made in view of the problems described above, and has a simple structure and suppresses the drooping of the wire harness routed between the vehicle body and the sliding door and regulates the curved trajectory of the wire harness. An object of the present invention is to make the wire harness smoothly follow the opening / closing operation of the sliding door while preventing interference with the peripheral members.

In order to solve the above-mentioned problem, the cross wiring region in which both sides in the length direction of the wire harness are inserted and supported by support members provided on the vehicle body and the sliding door, respectively, and the bending operation is performed in accordance with the opening / closing operation of the sliding door. It is a mounting structure of a wire harness for feeding power to the sliding door,
The wire harness is externally protected with a tube, and a belt-shaped spring plate for preventing drooping and for controlling a curved locus is provided on one side of the tube from a support member on the vehicle body side to a required position in the crossover region. The slide is arranged along the outer surface, and one end of the spring plate is fixed to the support member, and the other end of the spring plate is slidably attached to the outer surface of the tube at the required position. A mounting structure for a wire harness for feeding a door is provided.

  As described above, by placing a single strip of spring plate on the outer surface of one side of the tube that is sheathed on the wire harness, the bending of the tube in the vertical direction is restricted, and drooping due to the weight of the wire harness or the tube itself Can be suppressed. On the other hand, the strip-shaped spring plate arranged on the outer surface of one side of the tube can bend in the length direction (horizontal direction) that can follow the opening / closing operation of the slide door. It is possible to bend the wire harness in the length direction while following the opening / closing operation of the slide door.

  In addition, as described above, by arranging the spring plate in the section from the support member on the vehicle body side to a predetermined position in the cross-over area, the curved trajectory of the wire harness is regulated by the spring force generated in the bent spring plate. Thus, interference between the peripheral member and the wire harness can be prevented. For example, in the operation from the time when the sliding door is fully closed to the middle position of the sliding door half-opened state, the spring force of the spring plate arranged along the outer surface of one side of the tube and bent from the support member on the vehicle body side toward the vehicle front side is used. Since the cross wiring area of the wire harness is pulled toward the rear side of the vehicle and a curved trajectory that does not pass near the step where the occupant is likely to step on the vehicle can be taken, damage to the wire harness due to stepping or the like can be prevented. Further, in the operation from the intermediate position of the sliding door half-open state to the sliding door full-open position, the wire harness is urged by the spring force of the spring plate deflected from the support member on the vehicle body side to the vehicle rear side along the outer surface of the tube. Since it is possible to take a curved locus that does not bring the crossover area close to the tire house or tire, it is possible to prevent interference with the tire house or the like and prevent damage to the wire harness.

  In addition, as described above, since the region where the spring plate is arranged is a section of a predetermined length from the support member on the vehicle body side, the flexible region where the spring plate is not placed (from the spring plate tip to the slide door side support member) The wire harness can be smoothly bent by the crossover routing area). Therefore, since it is possible to flexibly follow the region where the spring plate is not placed along the vertical movement of the sliding door, it is not necessary to provide a vertically movable mechanism as in the conventional case, and the structure can be simplified. it can.

  In addition, as described above, one end of the spring plate is fixed to the support member, and the other end of the spring plate is slidably attached to the outer surface of the tube at the required position, so that it is externally mounted on the wire harness and bends. The followability of the spring plate to the tube to be improved can be enhanced, and the spring force can be applied to the tube by always keeping the spring plate along the outer surface of the tube regardless of the curved state of the tube.

  As described above, the belt-shaped spring plate for preventing drooping and for controlling the curved trajectory of a predetermined length is provided on the outer surface of one side of the tube sheathed on the wire harness routed between the vehicle body and the sliding door. With a simple structure that is slidably arranged from the side support member, the wire harness can be smoothly curved to follow the opening / closing operation of the slide door while preventing interference with the peripheral member. Therefore, it is not necessary to use an expensive cable guide as in the prior art, and it can be easily applied to a vehicle having a small distance between the sliding door and the vehicle body when fully opened, and a wire is provided between the vehicle body and the sliding door. Since it is possible to bridge the harness in a state close to a straight line, it is possible to reduce the cost by minimizing the length of the crossover area.

  It is preferable that the spring plate is made of a steel plate, and the length of the spring plate is a length that reaches from 1/3 to 1/2 of the entire length of the wire harness crossing region from the support member on the vehicle body side.

  The steel plate used as the spring plate has a spring force that can sufficiently regulate the bending trajectory of the wire harness and also enables smooth bending in the length direction, so that it can be repeatedly bent as the sliding door opens and closes. It also has high strength. Among the steel plates, stainless steel plates are particularly preferably used because they are hard to rust and have high strength. When a stainless steel plate is used as the spring plate, the thickness is preferably about 0.1 to 0.6 mm.

  In addition, as described above, when the length of the spring plate is less than 1/3 of the entire length of the crossover region of the wire harness, the curve trajectory of the wire harness may not be sufficiently restricted. If the length of the wire harness exceeds 1/2 of the entire length of the crossover wiring area of the wire harness, the wire harness may not be smoothly curved.

  The spring plate is preferably disposed on the outer panel side of the slide door of the tube.

  When the wiring harness is routed between the sliding door and the vehicle body and the sliding door is opened and closed, the portion of the outer surface of the tube sheathed on the wiring harness that is located on the inner panel side when the sliding door is fully closed follows. It is a part that requires great elasticity for operation. Therefore, from the viewpoint of followability, without placing the spring plate on the outer surface of the tube that becomes the inner panel side when the slide door is fully closed, as described above, by arranging the spring plate on the opposite outer panel side, Smooth bending operation and regulation of the bending trajectory of the wire harness can both be achieved. In particular, by arranging the spring plate on the outer panel side, in the operation from the middle position of the sliding door half-open state to the sliding door full-open position, the spring plate is positioned on the tire house side so that the wiring wiring area of the wire harness is reduced. It can be surely regulated so as not to interfere with the tire house.

The wire harness is composed of a laminated body of round covered electric wires or a flexible flat cable (FFC), and the tube is a resin tube or a corrugated tube having a circular cross section or an oval cross section,
An annular spring holding material made of a resin molded product is slidably fitted on the tube, and a spring plate locking portion is protruded from a part of the outer peripheral surface of the spring holding material. A pair of pins project from the inner surface of the insertion hole into which the other end of the spring plate is inserted, and the pins are locked in locking grooves provided on both sides in the width direction of the spring plate.

  In addition, the tube is a corrugated tube having a circular cross-section or an oval cross-section, and an annular spring holding material made of a resin molded product is provided on the corrugated tube. A spring plate insertion portion projects from a part of the outer peripheral surface of the spring holding material, and the spring plate is slidably inserted into the spring plate insertion portion of the spring holding material fixed to the corrugated tube. Good.

  As described above, as the wire harness, either a round covered electric wire group or a flexible flat cable (FFC) laminate can be used, but if an FFC laminate excellent in curvature is used, It is not necessary to provide a rotation mechanism (rotation end) for rotatably supporting the wire harness on the support member, and the structure can be further simplified.

Further, as described above, by using a resin tube or a corrugated tube as the tube, smooth bending is possible, and it is particularly preferable to use a corrugated tube from the viewpoint of followability. As a material for the corrugated tube, for example, rubber such as EPDM or various elastomers can be used.
Further, as described above, the tube can be appropriately selected in terms of the cross-sectional shape of the tube depending on the shape of the wire harness to be inserted, such as a circular cross-sectional shape, an elliptical cross-sectional shape, etc. When the tube is sheathed on the wire harness, the cross-sectional shape of the tube is preferably an oval shape.

Further, as a structure for slidably attaching the spring plate to the outer surface of the tube, as described above, an annular spring holding material in which a spring locking portion into which the spring plate is inserted and locked projects from a part of the outer peripheral surface, It is good also as a structure slidably fitted to a tube, or a spring insertion part protrudes from a part of the outer peripheral surface of an annular spring holding material that is fitted and concavo-convexly fitted to a corrugated tube, A structure may be adopted in which a spring plate is slidably inserted into the spring insertion portion.
When the annular spring holding material is slidably fitted onto the tube as in the former case, the inner surface of the spring holding material is R to improve the slidability of the spring holding material. It is preferable that the surface treatment is performed and the dimensions are set so that a slight clearance is formed between the inner peripheral surface of the spring holding member and the outer peripheral surface of the tube.
Also, in the latter case, in the case where the spring plate is slidably inserted into the spring insertion portion of the annular spring holding member, in order to improve the slidability of the spring plate, It is preferable that the dimensions are set so that a slight clearance is formed between the peripheral surface and the outer peripheral surface of the spring plate.

  As described above, the annular spring holding material is preferably made of a resin molded product, and examples of the resin forming the spring holding material include PP and PBT.

  As described above, according to the present invention, a belt-shaped band for preventing drooping and restricting a curved trajectory having a predetermined length is formed on one side outer surface of a tube sheathed on a wire harness routed between a vehicle body and a sliding door. By slidably arranging the spring plate from the support member on the vehicle body side, the wire harness is smoothly bent while controlling the trajectory of the wire harness with a simple structure to prevent interference with peripheral members. Thus, the sliding door can be opened and closed. Therefore, it is not necessary to use an expensive cable guide as in the prior art, and it can be easily applied to a vehicle in which the distance between the sliding door and the vehicle body when fully opened is small, and to respond to the vertical movement of the sliding door. There is no need for a vertically movable mechanism. In addition, since the wire harness can be bridged between the vehicle body and the sliding door in a straight line, the length of the crossover area can be minimized and the cost can be reduced. Can do.

Embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment of the present invention.
As shown in FIG. 1, the wire harness W / H for feeding power to the slide door 20 composed of a group of round-coated wires includes a slide door side support member 22 provided on the slide door 20 on both sides in the length direction, and a vehicle body 21. The wire harness W / H is made to follow the opening / closing operation of the slide door 20 by bending the connecting wiring region between the support members 22 and 23. Yes.

  Specifically, the wire harness W / H is externally protected with a corrugated tube 10 (material: PP), and the long diameter side of the corrugated tube 10 having an elliptical cross section is in the vertical direction, and the short diameter side is in the horizontal direction. One end of the corrugated tube 10 is fixed to the slide door side support member 22 and the other end of the corrugated tube 10 is fixed to the vehicle body side support member 23. Further, the vehicle body side support member 23 is arranged along the one side outer surface 10a of the corrugated tube 10 and, more specifically, along the one side outer surface 10a that becomes the outer panel side of the sliding door 20 when the sliding door is fully closed (P6). One strip-shaped spring plate 11 for preventing drooping and for controlling the curved trajectory is disposed up to a position reaching 1/3 of the entire length of the crossover region of the wire harness W / H. In the present embodiment, the spring plate 11 is formed from a stainless steel plate, the thickness of the spring plate 11 is 0.5 mm, and the vertical width of the spring plate 11 is about ½ of the major axis of the corrugated tube 10. Yes.

  One end of the spring plate 11 is fixed to the vehicle body side support member 23 together with one end of the corrugated tube 10, while the other end of the spring plate 11 is slidably attached to the outer surface of the corrugated tube 10. Specifically, an annular spring holding member 12 made of a resin molded product as shown in FIG. 2 and FIG. 3 is slidably fitted to the corrugated tube 10, and a part of the outer peripheral surface of the spring holding member 12 is provided. The other end of the spring plate 11 is inserted into the insertion hole 12a-1 of the protruding spring plate locking portion 12a, and a pair of pins 12a-2 protruding from the inner surface of the insertion hole 12a-1 of the spring plate locking portion 12a. Is locked to locking grooves 11 a provided on both sides in the width direction of the spring plate 11, so that the other end of the spring plate 11 is fixed to the spring holding member 12. That is, by fitting the slidable spring holding portion 12 to the corrugated tube 10, the other end of the spring plate 11 fixed to the spring holding material 12 can be slidable with respect to the outer surface of the corrugated tube 10. it can. In addition, in order to improve the slidability of the spring holding material 12, an R surface treatment is applied to the inner peripheral surface 12 b of the spring holding material 12, and when the spring holding material 12 is externally fitted to the corrugated tube 10, the spring holding material. The dimensions are set so that a slight clearance is formed between the inner peripheral surface 12 b of the twelve and the outer peripheral surface of the corrugated tube 10. In the present embodiment, the spring holding member 12 is formed from PP.

  The connector connected to the sliding door side support member 22 side terminal of the wire harness W / H covered with the corrugated tube 10 is connected to the terminal connector of the door harness routed in the sliding door 20, and the wire harness W / The connector connected to the vehicle body side support member 23 side terminal of H is connected to the connector of the wire harness terminal wired in the vehicle body 21. In the present embodiment, the slide door side support member 22 is provided with a rotation end 22a so that the wire harness W / H can be rotatably supported.

  P1 to P6 in FIG. 1 and FIGS. 4A to 4C indicate the curved trajectory of the wire harness W / H from the fully open state to the fully closed state of the slide door 20. The fully open state is shown, and P6 shows the fully closed state. P2 to P5 indicate a half-open state, and P4 indicates a curved state at an intermediate position in the half-open state. The wire harness W / H covered with the corrugated tube 10 follows the opening / closing operation of the sliding door 20 while smoothly bending.

  As shown in FIGS. 1 and 4A, in the operation from the sliding door 20 fully closed state (P6) to the intermediate position (P4) of the sliding door 20 half-opened state, the corrugated tube 10 is along the one side outer surface 10a. The transition wiring region of the wire harness W / H is pulled to the rear side of the vehicle by the spring force of the spring plate 11 that is arranged and bent from the vehicle body side support member 23 toward the front side of the vehicle. Take a curved trajectory that does not pass through.

  Further, as shown in FIGS. 1 and 4B, at the intermediate position (P4) of the sliding door 20 half-opened state, the spring plate 11 becomes straight and the spring force does not act, and the spring plate 11 is moved alongside. The crossing area A that is not aligned is bent through the gap between the tip of the spring plate 11 and the slide door 20.

  Further, as shown in FIGS. 1 and 4C, in the operation from the intermediate position (P4) of the sliding door 20 half-opened state to the sliding door 20 fully-opened state (P1), the sliding door-side support member 22 While the rotation end 22a rotates, the routing area is bridged between the slide door 20 and the vehicle body 21 in a state of being close to a straight line, and the vehicle is supported from the vehicle body side support member 23 along the one side outer surface 10a of the corrugated tube 10. A curved trajectory that does not cause the crossover portion of the wire harness to interfere with the tire or the tire house 21A is taken by the spring force of the spring plate 11 bent rearward.

  As described above, by arranging a single strip-shaped spring plate 11 on one side outer surface 10a of the corrugated tube 10 to be sheathed on the wire harness W / H, the bending of the corrugated tube 10 in the vertical direction is restricted, It is possible to suppress sagging due to the weight of the wire harness W / H or the corrugated tube 10 itself. On the other hand, the spring plate 11 disposed on the outer surface 10a on one side of the corrugated tube 10 can cause bending in the length direction (horizontal direction) that can follow the opening / closing operation of the slide door 20. The wire harness W / H sheathed with the tube 10 can be bent in the length direction while following the opening / closing operation of the slide door 20.

  Further, as described above, by arranging the spring plate 11 from the vehicle body side support member 23 to a predetermined position in the crossover region, the curved locus of the wire harness W / H is caused by the spring force generated in the bent spring plate 11. Since it can regulate, damage to wire harness W / H can be prevented.

  Furthermore, as described above, the region where the spring plate 11 is disposed is a section from the vehicle body side support member 23 to a predetermined position (in this embodiment, the position reaching the third of the entire wiring region from the vehicle body side support member 23 to the predetermined position). Therefore, the wire harness W / H can be made smooth by the flexible crossover area A (the crossover area from the front end of the spring plate to the sliding door side support member) where the spring plate 11 is not placed. Can be curved. Accordingly, since it is possible to flexibly follow the vertical movement of the slide door 20 in the region A where the spring plate 11 is not aligned, there is no need to provide a conventional vertically movable mechanism.

  In addition, as described above, one end of the spring plate 11 is fixed to the vehicle body side support member 23, and the other end of the spring plate 11 is slidably attached to the outer surface of the corrugated tube 10 at a required position, thereby enabling the wire harness W. / H improves the followability of the spring plate 11 to the corrugated tube 10 which is bent and operates, and the spring plate 11 is always along the outer surface of the corrugated tube 10 regardless of the curved state of the corrugated tube 10 to corrugate the spring force. It can be made to act on the tube 10.

  That is, according to the configuration of the present embodiment, the wire harness W / H is smoothly curved while controlling the trajectory of the wire harness W / H with a simple structure to prevent interference with peripheral members, and the sliding door 20 is bent smoothly. Therefore, it is not necessary to use an expensive cable guide and can be easily applied to a vehicle having a small distance between the sliding door 20 and the vehicle body 21 when fully opened, and the vehicle body 21 and the sliding door. Since the wire harness W / H can be bridged between the wire 20 and the wire 20 in a state close to a straight line, the length of the crossover area can be minimized and the cost can be reduced.

FIG. 5 shows a second embodiment of the present invention.
In the second embodiment, as shown in FIG. 5, an annular spring holding material 32 provided with unevenness 32 b that fits with the unevenness of the corrugated tube is fixed to the inner peripheral surface, and the spring holding material 32 is partially attached to the outer peripheral surface. The configuration is the same as that of the first embodiment except that the spring plate insertion portion 32a protrudes and the spring plate 31 is slidably inserted into the spring plate insertion portion 32a.
In order to improve the slidability of the spring plate 31, the dimensions are set so that a slight clearance is formed between the inner peripheral surface of the spring plate insertion portion 32 a and the outer peripheral surface of the spring plate 31.

  Also in the second embodiment, similarly to the first embodiment, the wire harness W / H is smoothly curved and slid while controlling the trajectory of the wire harness W / H with a simple structure to prevent interference with peripheral members. The opening / closing operation of the door 20 can be followed.

FIG. 6 shows a third embodiment of the present invention.
