JP 2003-25850 A

  In the above-described conventional sliding door feeding structure, considering the case where the crossover part (crossover harness guide) is routed above the step at the vehicle entrance / exit, the crossover part interferes with the above step when the slide door is opened and closed. It is necessary to provide clearance so as not to

  The clearance between the step and the crossing portion needs to be ensured even during the opening / closing operation of the sliding door, but the clearance is narrow due to a sag phenomenon caused by the crossing portion becoming substantially U-shaped during the intermediate state in the opening / closing operation. Therefore, there is a problem that the possibility that the crossing part interferes with the step becomes high.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a sliding door power feeding structure having a structure in which the hanging portion does not easily drop even during the opening / closing operation of the sliding door.

  The sliding door feeding structure according to claim 1 of the present invention is a sliding door feeding structure for electrically connecting a vehicle body side electrical component and a sliding door side electrical component, and is disposed in the sliding door.

  In the first aspect of the present invention, since the rotating substrate at the moving end coincides with the rotation axis of the rotating end and has a closed planar opening having no open area in plan view, a load is applied to the rotating end. However, the rotating end does not tilt with respect to the rotating substrate.

  As a result, it is possible to obtain a sliding door power feeding structure having a structure in which the hanging portion conductive path mechanism portion is unlikely to hang down even during the opening / closing operation of the sliding door.

  In the present invention of claim 2, the rotating substrate includes first and second opening peripheral portions having upper and bottom surfaces that are recessed from other regions around the opening portion, so that each other along the first direction. By using only two molds that are opposite male and female molds, it is possible to relatively easily obtain a moving end in which an opening that does not have an open area in plan view is formed on the rotating substrate.

It is supported by.

  More specifically, the slide door 14 is movable between the closed position P1 on the front side of the vehicle and the open position P2 on the rear side of the vehicle by moving mainly in the vehicle front-rear direction. When the slide door 14 moves from the closed position P1 to the open position P2, the slide door 14 also moves outward in the vehicle width direction in order to avoid interference with the vehicle body 12. At this time, the movement amount of the lower end portion of the slide door 14 in the vehicle width direction is set to be larger than the movement amount of the upper end portion of the slide door 14. Thereby, when the lower end part of the slide door 14 moves to the open position P2 from the closed position P1, it moves also upwards (for example, about 10-40 mm).

<Overall configuration of sliding door feeding structure>
Next, the overall configuration of the sliding door power feeding structure of the present embodiment will be described. 4 is a schematic perspective view showing the overall configuration of the sliding door feeding structure, FIG. 5 is a schematic side view showing the entire configuration of the sliding door feeding structure, and FIG. 6 is a schematic plan view showing the entire configuration of the sliding door feeding structure.

  FIG. 7 is a fragmentary perspective view showing the harness guide rail member 42 and the moving end 46. As shown in FIGS. 4 to 7, the harness guide rail member 42 is a member that is attached and fixed to the slide door 14 along the vehicle front-rear direction, and the moving end 46 moves along the harness guide rail member 42. It is a member arranged in a possible manner.

  More specifically, the harness guide rail member 42 has a pair of guide side plate portions 43 and a spacer member 44. The guide side plate portion 43 is formed in a substantially rectangular plate shape. The spacer member 44 is a member that connects and supports the pair of guide side plate portions 43 in a substantially parallel posture with a gap therebetween. Here, the spacer member 44 is formed in a substantially bar-like member, and the guide side plate portion 43 and the spacer member 44 are in a state where the spacer member 44 is interposed between both ends of the pair of guide side plate portions 43. The pair of guide side plate portions 43 are connected and supported in a substantially parallel posture by fixing them with screws.

  In addition, a pair of elongated protrusion-like rail portions 43 a are formed along the longitudinal direction of the guide side plate portion 43 at the intermediate portion in the width direction of one main surface of the guide side plate portion 43. The pair of guide side plate portions 43 are arranged and supported so as to protrude inward of the pair of guide side plate portions 43 in a state where the pair of guide side plate portions 43 are connected and supported in a substantially parallel posture as described above. Yes. In this way, a configuration in which the moving end 46 is linearly guided is realized with a configuration in which the pair of rail portions 43a face each other with a gap therebetween.

  The guide side plate portion 43 is formed as a member having substantially the same cross-sectional shape along the longitudinal direction.

  And as shown in FIG.5 and FIG.6, the attachment piece 42P is attached and fixed to the outer surface of one guide side board part 43 via the screw | thread etc. As shown in FIG. The harness guide rail member 42 is attached and fixed to the lower end portion of the slide door 14 and the like in a posture along the vehicle front-rear direction via the attachment piece 42P and the like.

  Furthermore, a harness guide fixing member 48 is attached to the upper part of the intermediate portion in the longitudinal direction of the harness guide rail member 42. The harness guide fixing member 48 is formed as a plate-like member protruding above the harness guide rail member 42, and at a fixed position above the harness guide rail member 42, the wire harness 32 in the sliding door and the bending in the sliding door are formed. The other end portion of the operation guide member 36 is fixedly supported. The harness guide fixing member 48 is formed with a space communicating with the space between the pair of guide side plate portions 43, and a slide door bending operation guide member 36, which will be described later, is arranged so as to be able to be bent in the space. It is installed.

  Further, the moving end 46, which is a slide material, can be disposed between the pair of guide side plate portions 43, and can be disposed between the pair of rail portions 43a on each of both side portions. A groove 46g is formed along the vehicle longitudinal direction. In addition, the moving end 46 is disposed between the pair of guide side plate portions 43 while the protruding portions 46a are disposed between the pair of rail portions 43a (and a part of the rail portion 43a is in the groove portion 46g). Thus, the moving end 46 is supported by the harness guide rail member 42 so as to be movable along the longitudinal direction thereof.

  Further, a slide door side connecting portion 47A capable of connecting the slide door in-bending operation guide member 36 is formed at the upper end portion of the moving end 46, and a vehicle body side connecting portion 47B is provided at the lower end portion of the moving end 46. A rotating end 49 is rotatably disposed on a rotating board 47r that forms the bottom surface of the vehicle body side connecting portion 47B (see FIG. 7), and the sliding door interbody bending operation guide member is provided via the rotating end 49. 60 are connected.

  Then, the slide door internal bending motion guide member 36 is connected to the slide door side connecting portion 47 </ b> A, whereby the slide door internal wire harness 32 is connected to the moving end 46.

  The wire harness 32 in the sliding door is configured by bundling a plurality of electric wires in a linear shape, and is itself a linear material that can be freely bent.

  In addition, the sliding door inner wire harness 32 is provided with an inner sliding door bending operation guide member 36, whereby the sliding door inner wire harness 32 is bent in one plane (a plane substantially parallel to the side of the vehicle body). Be guided to do.

  More specifically, the sliding door bending motion guide member 36 includes a plurality of link members 37 having a pair of side pieces supported at intervals, and each link member 37 is arranged around a predetermined axis. By being connected so as to be rotatable, a linear member that can be bent in one plane as a whole is formed. Further, in the sliding door bending operation guide member 36, a harness housing space is formed along the longitudinal direction of the sliding door wire harness 32, so that the sliding door wire harness 32 can be inserted into the sliding door bending motion guide member 36. It is inserted into the harness housing space. Thereby, the wire harness 32 in the slide door is guided so as to be able to bend in one plane.

  One end portion of the sliding door bending operation guide member 36 is coupled between the pair of guide side plate portions 43 to the moving end 46 via a sliding door side coupling portion 47A. The other end portion of the sliding door bending operation guide member 36 is fixedly attached to the upper end portion of the harness guide fixing member 48 through a fitting structure, a screwing structure, or the like. One end portion of the wire harness 32 in the slide door is electrically connected to the other end portion of the wire harness 52 between the slide door bodies to be described later via the slide door side connecting portion 47A through the moving end 46, and slides. The other end portion of the in-door wire harness 32 is electrically connected to the electrical component on the slide door side from the fixed portion via another wire harness, electric wire, and the like.

  The transition part conductive path mechanism part 50 is provided between the vehicle body 12 and the slide door 14, and includes a slide door inter-vehicle wire harness 52 and a slide door inter-vehicle bending operation guide member 60. As described above, the crossover conductive path mechanism 50 provided between the vehicle body 12 and the slide door 14 may be simply referred to as a “crossover”.

  5 is configured by bundling a plurality of electric wires in a linear shape, and is itself a linear material that can be bent freely like the wire harness 32 in the sliding door. Has been.

  The sliding vehicle body bending motion guide member 60 is externally mounted on the sliding door vehicle body wire harness 52 and is configured to guide the bending operation of the sliding door vehicle body wire harness 52. The sliding door body bending motion guide member 60 is formed of, for example, a bellows-like corrugated tube into which the sliding door body wiring harness 52 can be inserted.

  Further, as the sliding door interbody bending operation guide member 60, as in the sliding door bending operation guide member 36, a plurality of link members 37 are linearly connected mainly so as to be capable of bending operation within a predetermined plane. It may be.

  A vehicle body side mounting member 66 is connected to one end of the sliding door interbody bending operation guide member 60. Then, the vehicle body side attachment member 66 is attached to the vehicle body by a screwing structure or an engagement structure, so that one end of the sliding door interbody bending operation guide member 60 is attached to the vehicle body. The other end of the sliding door interbody bending operation guide member 60 is rotatably connected to a rotating end 49 provided on the rotating substrate 47r in the vehicle body side connecting portion 47B of the moving end 46.

  One end of the sliding door inter-vehicle wire harness 52 inserted into the sliding door inter-vehicle bending operation guide member 60 is connected to the vehicle body side electrical equipment from the vehicle body side mounting member 66 via another wire harness or electric wire. The other end of the wire harness 52 between the slide doors is electrically connected to the other end of the wire harness 32 in the slide door via the vehicle body side connecting portion 47B and the moving end 46. Connected.

  But the wire harness 52 between sliding door vehicle bodies and the wire harness 32 in slide door may be one continuous wire harness.

  The sliding door power feeding structure 20 follows the opening and closing of the sliding door 14 and bends and deforms the sliding door wire harness 32 and the sliding door inter-vehicle wire harness 52 while moving the moving end 46 to the harness guide rail member 42. It is set as the structure arrange | positioned so that a reciprocating movement is possible.

  In other words, in a state where the slide door 14 is in the closed position P <b> 1, one end of the slide door inter-vehicle wire harness 52 on the vehicle body side is on the vehicle rear side with respect to the harness guide rail member 42. For this reason, the moving end 46 is pulled to the vehicle rear side by the sliding door inter-vehicle wire harness 52 and is positioned on the vehicle rear side of the harness guide rail member 42. In this state, the in-slide door wire harness 32 is bent in a substantially J shape in which the linear portion on one end side (lower side) is shorter than the linear portion on the other end side (upper side) ( 4 and 5). Moreover, the wire harness 52 between the sliding doors is in a state extending along the vehicle front-rear direction while slightly curving between the moving end 46 on the sliding door 14 side and the vehicle body side mounting member 66 on the vehicle body 12 side. (See FIGS. 4 to 6).

  When the sliding door 14 is opened from the above state, the sliding door 14 moves mainly in the vehicle longitudinal direction and the vehicle width direction. As a result, one end of the sliding door inter-vehicle wire harness 52 on the vehicle body side moves relative to the harness guide rail member 42 toward the vehicle front side. Then, the moving end 46 is pulled toward the vehicle front side by the sliding door inter-vehicle wire harness 52 and moves to the vehicle front side of the harness guide rail member 42. Accordingly, the sliding door inner wire harness 32 bends along a plane substantially parallel to the side surface of the vehicle body under the guide state by the sliding door inner bending operation guide member 36, passes through a substantially U-shaped shape, and reaches its one end side (lower The straight line portion on the side) is longer than the straight line portion on the other end side (upper side), and is bent in a substantially J shape (see FIGS. 4 and 5).

  On the other hand, under the guide state by the sliding door interbody bending operation guide member 60, the sliding door interbody wire harness 52 bends mainly in a plane along the floor surface, and slides through a substantially S shape and a substantially U shape. It will be in the state extended while slightly curving between the moving end 46 by the side of the door 14, and the vehicle body side attachment member 66 by the side of the vehicle body 12 (refer FIGS. 4-6). That is, the crossing portion conductive path mechanism portion 50 is bent into a substantially S shape, a substantially U shape, or the like in an intermediate state in the opening / closing operation of the slide door 14, so that a drooping phenomenon occurs. There is a high possibility that the clearance with the conductive path mechanism unit 50 becomes narrow.

<Moving end and rotating end>
(Consideration of problems)
FIG. 13 is a perspective view showing a general structure of a moving end and a rotating end, and FIG. 14 is a perspective view showing a combined structure of a moving end and a fixed end.

  As shown in FIG. 13 (a), the moving end 46 can be disposed between a pair of rail portions 43a (see FIG. 7) provided between the pair of guide side plate portions 43 so as to be disposed between the protruding portion 46a and the groove portion. Since it is necessary to provide 46g, it is common to form the moving end 46 by a set of molds including a first mold directed in the direction D1 and a second mold directed in the direction D2 during molding. .

  Therefore, in the rotating substrate 47r of the vehicle body side connecting portion 47B which is the lower end portion of the moving end 46, a third mold having a sliding structure is further required to provide an opening having a closed shape in plan view, and an extra cost is required. Therefore, it is common to use the slot 47s having a long hole structure having an open area in plan view as a bearing portion of the rotating shaft of the rotating end 49 shown in FIG. 13 (b). As shown in FIG. 13 (a), the main body portion of the moving end 46 has a structure in which the moving end portions 46X and 46Y are formed separately and then connected to each other. There is no such problem.

  FIG. 15 is a sectional view schematically showing the sectional structure of the rotating end 49. As shown in FIG. 4A, the rotating end 49 is rotatably mounted in the moving end 46. At this time, the rotating shaft 49j below the rotating end 49 is rotatably inserted into a part of the space 47s, and normally stands upright. And as above-mentioned, the transfer part conductive path mechanism part 50 is attached to this rotation end 49 so that rotation is possible.

  However, as shown in FIG. 15 (b), when the load L1 is applied from the upper side to the lower side, the space portion 47s cannot restrict the tilting movement of the rotating shaft 49j. The direction of connection with the conductive path mechanism 50 may be slightly inclined downward.

  Therefore, by the above tilt. Since the sliding door interbody bending operation guide member 60 constituting the crossing portion conductive path mechanism portion 50 hangs downward from the other end portion to the one end portion, the clearance becomes narrow and the step of the entrance 13 is performed when the sliding door 14 is opened and closed. The problem of interference has not been completely avoided.

(Moving end after improvement)
FIG. 8 is a sectional view schematically showing the sectional structure of the moving end and the rotating end used in the present embodiment. FIG. 9 is a cross-sectional view schematically showing a situation when the load L1 is applied to the rotating end 49. As shown in FIG. FIG. 10 shows a top view of the rotating substrate 7r shown in FIG. For convenience of explanation, the moving end 46 having a general structure is described in FIGS. 5 to 7, but the present embodiment is not limited to the moving end 46 (vehicle body side connecting portion shown in FIGS. 5 to 7. 47B), the moving end 6 (vehicle body side connecting portion 7B) having the structure shown in FIGS. 8 to 10 is used.

  As shown in these drawings, the moving end 6 used in the present embodiment is provided at the central portion of the rotating substrate 7r by providing a restriction wall portion 7c at a location corresponding to the space 47s portion of the conventional moving end 46. The structure which has the bearing part 7j (opening part) of the substantially circular shape in planar view is exhibited. In other words, the rotating substrate 7r has a closed planar bearing portion 7j that matches the cross-sectional shape of the rotating shaft 49j of the rotating end 49 and has no open portion in plan view.

  For this reason, as shown in FIG. 9, even if the load L1 is applied from the upper side to the lower side, the rotation end 49 does not tilt forward and downward due to the deflection due to the presence of the regulating wall portion 7c. Therefore, there is an effect that it is possible to surely avoid the possibility of interfering with the step of the entrance 13 when the slide door 14 is opened and closed.

(Molding with mold)
11 and 12 are explanatory views schematically showing a method of forming the bearing portion 7j portion of the rotating substrate 7r of the moving end 6 (vehicle body side connecting portion 7B) by a mold, FIG. 11 is a side view, and FIG. It is a top view. In FIGS. 11 and 12, for convenience of explanation, the forming method of the bearing portion 7j is schematically shown in an easily understandable content.

  As shown in FIGS. 11 (a) and 12 (a), the pair of molds 1 and 2 have bearing part forming parts 1j and 2j at positions facing each other in plan view, and the bearing part forming part 1j is formed. The height h1 is arranged to be higher by the thickness t2 of the bearing portion forming portion 2j (h1 = t2), and the thickness t21 of the tip portion 2j1 of the bearing portion forming portion 2j is made lower by about half the thickness t2. Has a step structure.

  Then, as shown in FIGS. 11 (a) and 12 (a), the mold 1 and the mold 2 are moved in the direction D1 and the direction D2, respectively, in the state shown in FIGS. 11 (b) and 12 (b). The rotating substrate 7r is molded by fixing and injection molding of a resin material.

  As shown in FIGS. 11 (b) and 12 (b), in molding, the mold 1 is such that all of the bearing portion forming portion 1j and a portion of the bearing portion forming portion 2j of the die 2 intersect in plan view. In only the portion where the bearing portion 7j is formed, the bearing portion forming portion 1j is arranged on the bearing portion forming portion 2j so as to be stacked without being transparent.

  As a result, by using a pair of the mold 1 and the mold 2 that are a male mold and a female mold that face each other without using a mold having a slide structure, the planar view open area such as the space 47s can be rotated. Without causing the substrate 7r, a substantially circular bearing 7j (opening) in a plan view can be formed in the center of the rotating substrate 7r.

  At this time, the first direction bearing peripheral portion 7r1 and the second direction bearing peripheral portion 7r2 formed around the bearing portion 7j reflecting the bearing portion forming portions 1j and 2j have the following characteristics. The first direction bearing peripheral portion 7r1 corresponds to the regulation wall portion 7c, and is formed with a thickness (t2-t21) extending from the bearing portion 7j to the end portion in the direction D2 and having an upper surface recessed from the other region. The second direction bearing peripheral portion 7r2 is formed to extend from the bearing portion 7j to the end portion in the direction D1 and has a bottom surface recessed from other regions. The regions of the rotating substrate 7r other than the first and second direction bearing peripheral portions 7r1 and 7r2 are recessed on the top surface and the bottom surface with the thickness of the first direction bearing peripheral portion 7r1 and the thickness of the second direction bearing peripheral portion 7r2. Formed without.

(effect)
Thus, in the sliding door power feeding structure 20 of the present embodiment, the rotating board 7r in the vehicle body side connecting portion 7B of the moving end 6 can be inserted in conformity with the cross-sectional shape of the rotating shaft 49j of the rotating end 49. It has a bearing portion 7j which is a substantially circular opening. That is, the bearing portion 7j provided on the rotating substrate 7r is a closed planar opening portion that does not have an open area in plan view, matching the cross-sectional shape of the rotating shaft 49j of the rotating end 49. For this reason, as shown in FIG. 9, even if a load L1 is applied to the rotation end 49 from above, the rotation end 49 is inclined with respect to the rotation substrate 7r due to the presence of the regulating wall portion 7c (the first direction bearing peripheral portion 7r1). There is nothing.

  As a result, it is possible to obtain a sliding door power feeding structure having a structure in which the hanging portion (crossing portion conductive path mechanism portion 50) does not easily drop even during the opening / closing operation of the sliding door 14.

  In addition, the rotating end 49 is not inclined with respect to the rotating substrate 7r by the rotating substrate 7r having the bearing portion 7j, so that the rotating end 49 can be easily moved away from the moving end 6 even if an external force is applied to the rotating end 49 due to being stepped on. It can also be expected to improve the detachment strength.

  Further, the rotating substrate 7r at the lower end of the moving end 6 has a first direction bearing peripheral portion 7r1 formed in the first direction (direction D2) with respect to the bearing portion 7j, and has an upper surface recessed from other regions. The second direction bearing peripheral portion 7r2 formed in the second direction (the direction along the direction D1, opposite to the first direction) with respect to the bearing portion 7j has a bottom surface that is recessed from other regions. .

  Therefore, as described with reference to FIGS. 11 and 12, by using only the two molds 1 and 2 that are the male mold and the female mold facing each other along the first direction, the rotation can be performed. The moving end 6 having a structure in which the bearing portion 7j is formed at the center of the substrate 7r can be obtained relatively easily.
