JP 2008-148539 A (FIG. 8C)

  As a thing similar to the said electric power feeder 41, the electric power feeder shown in FIG. 4 is mentioned.

  The power feeding device 51 is provided with a protector made up of a substantially rectangular protector base 52 made of synthetic resin and a protector cover 53, a link arm 54 pivotally supported in the protector, and a link arm 54 facing upward. A torsion coil spring 55 is provided, and a harness holding member 56 is provided rotatably at the tip of the link arm 54.

  A link arm 54 with a harness holding member 56 and a torsion coil spring 55 are assembled to the protector base 52, and one end of a synthetic resin corrugated tube 57a of the wire harness 57 is held and fixed in the harness holding portion 56b of the harness holding member 56. The electric wire portion 57b led out from the corrugated tube 57a is bent and wired in a substantially S shape inside the protector, and is led out to the outside while being fixed at the opening 58 on the front end side of the protector.

  The protector cover 53 is formed with a shorter skirt than the protector base 52 and is locked to the protector base 52. The protector is fixed to the door inner panel of the sliding door of the automobile with a bolt or the like in each hole 61. FIG. 4 shows a state when the sliding door is fully closed.

  The wire harness 57 is led out to the outside through the bottom part of the sliding door trim 29 made of synthetic resin from the long bottom opening 59 between the protector base 52 and the bottom part of the protector cover 53, and the other end of the corrugated tube 57a is The electric wire portion 57c held by the harness fixing portion 26 on the vehicle body side and led out from the other end of the corrugated tube 57a is connected to a wire harness (not shown) on the vehicle body side (power supply side). The operation of the power feeding device 51 of FIG. 4 is substantially the same as that of the power feeding device 41 of FIG.

  However, in the power feeding device 51, as shown in the BB cross section of FIG. 4 in FIG. 5, the skirt 53a of the protector cover 53 is formed to be considerably shorter than the skirt 52a of the protector base 52. In particular, when the sliding door of FIG. 4 is fully closed, the harness holding member 56 and the wire harness portion in the vicinity thereof are greatly exposed to the outside from the skirt 53a of the protector cover 53, and the link arm 54 and the harness holding member 56 are assembled. When the backlash is large, the guide regulation by the protector cover 53 is lost, the shake of the protector increases in the thickness direction (vehicle width direction), and it interferes with the protector base 52 to cause abnormal noise or wear. There was a concern that it could be combined.

  This concern is not limited to the sliding doors of automobiles, and can occur in the same way when power feeding devices are mounted on sliding doors of vehicles other than automobiles, sliding doors of devices other than vehicles, and the like. These slide doors and the like are collectively referred to as a slide structure, and the vehicle body and the like are collectively referred to as a fixed structure.

  In view of the above points, the present invention generates interference with the protector base, abnormal noise associated with the protector base, and the like even when the wire harness and the harness holding member are exposed to the outside from the skirt of the protector cover along the protector base. It is an object of the present invention to provide a power supply device for a slide structure without any problem.

  In order to achieve the above object, a power supply device for a slide structure according to claim 1 of the present invention includes a link arm rotatably provided on a protector base, and the link arm attached in a harness surplus length absorption direction. An elastic member for biasing, a harness holding member provided on the link arm, a protector cover attached to the protector base, covering the link arm and exposing the harness holding member to the hem side, and In a power feeding device for a slide structure including a wire harness held by a harness holding member and routed along the protector base, the harness holding member is provided with a slide engagement portion, and the slide engagement portion is An arcuate guide portion that is slidably engaged and held is provided on the protector base.

  With the above configuration, for example, the protector base is fixed to the slide structure, the harness holding member holds one of the wire harnesses, the fixed structure holds the other wire harness, and the slide structure is opened and closed with respect to the fixed structure. When moved in the direction, the slide engaging portion of the harness holding member rotates along an arcuate locus while sliding along the guide portion of the protector base. The arc shape is a shape including an arc-shaped portion, and the radius of curvature is not limited to a constant value. Since the slide engagement portion is engaged and held by the guide portion, the harness holding member is prevented from flapping (swinging) in the protector base thickness direction.

  The protector base and the protector cover constitute a protector, and the link arm and the elastic member are protected from interference with the outside in the protector. Since the harness holding member is exposed from the protector cover, the harness holding member can be enlarged (reinforced), and the protector can be reduced in weight by the protector cover having a short hem.

  The power supply device for the slide structure according to claim 2 is the power supply device for the slide structure according to claim 1, wherein the harness holding member is rotatably provided on the link arm, and the guide portion is horizontally long. The protector base is formed with a gradually increasing curvature radius in the longitudinal direction.

  With the above configuration, the guide portion is formed in an arc shape with a small radius on the end side in the short direction of the protector base, and is formed in an arc shape with a large radius on the end side in the longitudinal direction of the protector base. In a state where the holding member extends in a shape that is linear or close to a straight line, the harness holding member is positioned on the end side in the short direction, and the link arm and the harness holding member are bent to shorten the overall length, The harness holding member is located on the end side in the longitudinal direction (positioned without projecting greatly from the end side in the longitudinal direction), and the harness holding member smoothly rotates along the shape of the horizontally long protector base. It becomes possible.

  According to the first aspect of the present invention, when the wire harness is rotated (swinged) together with the link arm, the harness holding member is moved along the protector base by the engagement between the slide engaging portion and the guide portion. Because it rotates smoothly while the position is regulated without backlash in the base thickness direction, even if the skirt of the protector cover is short, interference between the harness holding member and the protector base and interference between the wire harness and the protector base are prevented. Occurrence of noise due to the interference, damage to the harness holding member, wear of the wire harness, and the like are prevented, and reliability of constant power supply to the slide structure is increased.

  According to the second aspect of the present invention, the harness holding member can be smoothly rotated (swinged) along with the wire harness along the horizontally long protector base without interference with the outside.

The protector base 2 has a vertical base plate portion 16 that is parallel to the base plate portion 12 and has a shorter skirt than the base plate portion 12, and the peripheral wall formed by the upper wall 15 and the front wall (14) of the protector cover 3 is a protector. It overlaps with the outer side of the surrounding walls 13 and 14 of the base 2 (refer FIG. 2), and is mutually locked by locking means (not shown), such as a locking frame piece and an engaging protrusion.

  The upper wall 15 of the protector cover 3 continues perpendicularly to the narrow portion 16a of the vertical substrate portion 16 at the rear, and the lower end of the narrow portion 16a is parallel (horizontal) to the upper end (upper wall 15). Reference numeral 16 a denotes a length of about ¼ of the substrate portion 16 and extends forward. The wide portion (16) follows the wide portion (represented by reference numeral 16) of the substrate portion 16, and the wide portion (16) has an arc shape in the latter half of the protector base 2. The arcuate end portion 16b of the latter half having a smaller diameter than the end portion 12a and the substantially horizontal straight end portion 16c of the front half shorter than the straight end portion 12b of the front half of the protector base 2 are provided.

  In particular, the rear inner surface of the protector base 2 is greatly exposed from the protector cover 3 by the narrow portion 16a at the rear of the protector cover 3, and the exposed length of the protector base 2 (from the rear end 12a of the protector base 2 to the rear end of the protector cover 3). (Horizontal length up to 16b) gradually decreases from the top to the bottom, and is minimum at the straight lower end 12b of the first half of the protector base 2. The protector 4 may be slightly inclined (slightly inclined) to the sliding door (not shown) in each hole 17 on the rear end side of the narrow portion 16a of the protector cover 3 and the front end side of the wide portion (16). ) It is fixed to the metal sliding door panel by bolting.

  A long, substantially arc-shaped guide hole 10 is formed along the straight end portion 12b of the first half from the arcuate end portion 12a of the second half portion of the substrate portion 12 at the exposed portion, that is, the bottom portion of the substrate portion 12 of the protector base 2. ing. The guide hole 10 is composed of a small arc-shaped portion 10a in the latter half and a large arc-shaped portion 10b in the first half, and a rear upper end (starting end) 10c of the guide hole 10 is slightly below the narrow portion 16a of the protector cover 3. The front lower end (termination) 10 d of the guide hole 10 is positioned rearwardly away from the vertical front end 12 c of the substrate portion 12 of the protector base 2. In the specification, the directions of up, down, front, back, left and right are made to coincide with the direction of the vehicle.

  Inside the protector covered with the protector base 2 and the protector cover 3, the base end of the link arm 5 is rotatably supported by the shaft portion 18 in the upper half of the front half, and the link arm 5 is in a full rotation range of 90 ° or more. The harness holding member 8 is connected to the tip of the link arm 5 via a hinge shaft 19 so as to be rotatable within a range of about 90 ° without being exposed to the outside from the protector cover 3.

  The harness holding member 8 includes a sub arm 6 that follows the hinge shaft 19 and a harness holding portion 7 that is integrally formed on the distal end side of the sub arm 6, and fully closes the slide door (not shown) of the automobile in FIG. At this time, the harness holding portion 7 and the front half of the sub arm 6 are exposed (projected) from the hem portion (the arc-shaped rear end portion 16b) of the protector cover 3, and when the sliding door is fully opened, that is, the wire harness 20 is When swinging forward, the front end side half of the harness holding part 7 is exposed from the skirt part (substantially linear lower end part 16 c) of the protector cover 3.

  Since the wire harness 20 is accommodated in the harness holding portion 7 and protected from interference with the outside, the protector cover 3 is short, and there is no problem even if the harness holding portion 7 is exposed from the protector cover 3. Further, even when the harness holding part 7 protrudes (enlarges) toward the protector cover 3 in the harness radial direction, the bottom part of the protector cover 3 is cut short, so that no interference occurs. The short protector cover 3 reduces the weight of the protector 4 and saves space on the mounting side (inside the sliding door).

  The slide engaging portion 11 is provided in the harness holding portion 7. That is, as shown in FIG. 2, a circular shaft portion 11 a is formed on the wall portion 21 on the back side of the harness holding portion 7 (near the substrate portion 12 of the protector base 2) in the longitudinal intermediate portion (substantially center) of the harness holding portion 7. A large-diameter disk-like head portion 11b is integrally provided at the tip of the shaft portion 11a.

  The harness holding portion 7 is composed of a corrugated tube holding portion 7a having a large diameter at the front end side half (a large diameter in the vertical direction in FIG. 1) and a small-diameter electric wire portion holding portion 7b (shown by a chain line) at the base end side half portion. The wall 21 on the back side is provided linearly and vertically in common with both the holding portions 7a and 7b. The corrugated tube holding portion 7a has a shape corresponding to an oblong corrugated tube 22 (FIG. 2) having a vertically long cross section, and the electric wire portion holding portion 7b has a circular electric wire portion (in a state where a plurality of electric wires are bundled) 23 or It has a shape corresponding to a flexible reticulated tube (substitute with reference numeral 23) covering the electric wire portion.

  A rib (not shown) on the inner peripheral surface of the corrugated tube holding portion 7a is engaged with the circumferential groove 22a of the corrugated tube 22, and the electric wire portion 23 is inserted into the electric wire portion holding portion 7b. When covered with a mesh tube, for example, a sharp barbed projection (not shown) on the inner surface of the electric wire portion holding portion 7b penetrates and engages the mesh tube. When a corrugated tube having a circular cross section is used, the corrugated tube holding portion 7a is also formed in a circular cross section.

  As shown in FIG. 2, a shallow concave groove 24 is provided in a long arc shape on the outer surface of the exposed bottom portion 12 ′ of the base plate portion 12 of the protector base 2 (a low convex wall 25 is long when viewed from the inner surface of the bottom portion 12 ′. The convex wall 25 connects the two support wall portions 25a in parallel with the skirt portion 12 'and the short support wall portion 25a before and after or perpendicular to the skirt portion 12' of the substrate portion 12. The long guide hole 10 is provided through the center of the protruding wall portion 25b in the width direction. The convex wall 25 (concave groove 24) is formed over the entire length of the guide hole 10 in FIG.

  A shaft portion 11a having a circular cross section of the slide engagement portion 11 is slidably engaged with the guide hole 10 with a slight clearance, the head portion 11b is accommodated in the groove 24, and the inner width of the groove 24 Is formed larger than the outer diameter of the head portion 11b, the depth of the concave groove 24 is formed slightly larger than the thickness of the head portion 11b, and the inner surface of the head portion 11b (the surface orthogonal to the shaft portion 11a) is formed in the concave groove 24. The head portion 11b prevents the shaft portion 11a from slipping out of the guide hole 10, and the harness is held on the flat protruding surface of the protruding wall portion 25b of the convex wall 25. The rear surface of the wall portion 21 of the portion 7 is slidably in contact.

  When the slide engaging portion 11 is integrally formed with the harness holding portion 7, a circular hole (not shown) that penetrates the head portion 11b is formed at the end (for example, the front end) 10d of the guide hole 10 of the protector base 2 in FIG. Keep it. When the slide engaging portion 11 is made of metal or the like and fixed to the harness holding portion 7 made of synthetic resin by screwing or the like, such a circular hole is unnecessary.

  The slide engaging portion 11 formed of the shaft portion 11a and the head portion 11b of the harness holding portion 7 is slidably engaged with the guide hole 10 of the exposed bottom portion 12 ′ of the base plate portion 12 of the protector base 2, so that the harness The holding portion 7 is always positioned along the protector base 2 without being separated from the protector base 2 toward the protector cover 3, thereby preventing the wire harness 20 from swinging in the protector thickness direction, and the harness holding portion 7 and the protector base. 2, interference between the sub-arm 6 and the protector base 2 and the protector cover 3, and interference between the wire harness 20 and the protector base 2, and abnormal noise caused by the interference, the harness holding member 8 and the wire harness. 20 wear and damage are reliably prevented.

  1, the wire harness 20 is pulled rearward with a harness fixing portion (rotary clamp) 26 on the vehicle body side as a fulcrum, and the harness holding portion 7 connects the slide engaging portion 11 to the protector. In a state of being engaged with the guide hole 10 of the base 2, the sub arm 6 is positioned slightly below the upper end (starting end) 10 c of the guide hole 10, the sub arm 6 is positioned obliquely rearward and downward, and the link arm 5 is smaller than the sub arm 6. The torsion spring 9 is located on the upper side at an inclination angle and urges the link arm 5 upward in the clockwise direction.

  The coil winding portion 9 a at the center of the torsion winding spring 9 is extrapolated to the shaft portion 18 of the protector base 2 so as to be loosely fitted, and one hook portion (end portion) 9 b of the torsion winding spring 9 is attached to the receiving portion 5 a of the link arm 5. The other flange portion (end portion) 9 c is engaged with the receiving portion 27 of the protector base 2.

  The electric wire portion 23 of the wire harness 20 passes through a gap (long opening) between the protector base 2 and the rear end portion 16b of the protector cover 3 from the opening 7c (FIG. 2) at the upper end of the harness holding portion 7 in the protector 4. Is bent into a substantially S-shape in the protector, is led out through the harness fixing portion 28 at the front end of the protector 4, and is connected to each auxiliary device (not shown) on the slide door side by a connector. .

  The corrugated tube portion 22 of the wire harness 20 is led obliquely downward from an opening 7d (FIG. 2) at the lower end of the harness holding portion 7, and passes through the inside of the bottom portion of the door trim 29 made of synthetic resin of the sliding door to It is routed to the harness fixing part 26 on the body side, and the electric wire portion 28a of the wire harness 20 is led out to the vehicle body side from the harness fixing part 26 and connected to a wire harness (not shown) on the vehicle body side (power supply side). Is done.

  As the slide door is opened rearward from the state of FIG. 1, the wire harness 20 tends to hang down due to its own weight when the slide door is half open, but the link arm 5 is lifted together with the wire harness 20 by the biasing force of the torsion spring 9. And the harness extra length (slack) is absorbed.

  When the sliding door is fully opened, the wire harness 20 swings while being pulled forward with the harness fixing portion 26 on the vehicle body side as a fulcrum, and the harness holding portion 7 engages the slide engaging portion 11 with the guide hole 10. In this state, it slides downward along an arcuate path along the guide hole 10 in a counterclockwise direction, and a large arc portion 10b on the lower end side of the guide hole 10 is slightly rearward from the front end 10d of the guide hole 10. Located away (with a margin).

  As the harness holding portion 7 rotates downward, the sub arm 6 rotates counterclockwise integrally with the harness holding portion 7 with the hinge shaft 19 as a fulcrum. For example, the sub arm 6 is the tip of the link arm 5 (stopper portion). The link arm 5 rotates downward and counterclockwise against the urging force of the torsion spring 9 integrally with the sub arm 6 at the rotation end position in contact with the sub arm 6.

  As the harness holding portion 7 is turned downward, the bending angle of the link arm 5 and the sub arm 6 is reduced to about 90 °, and the distance from the shaft portion 27 at the turning center to the harness holding portion 7 is shortened. The slide engaging portion 11 of the harness holding portion 7 slides smoothly without being caught along the guide hole 10 whose distance from the shaft portion 27 is shortened as it goes downward. The action when the sliding door is fully opened to fully closed is opposite to the sliding door closing process.

  In the above embodiment, the sub arm 6 is rotatably provided on the link arm 5. However, the sub arm 6 is removed, the link arm 5 is extended by that amount, and a harness holding portion is attached to the tip of the link arm (5). It is also possible to provide the (harness holding member) 7 directly (fixed) or rotatably. When the link arm 5 is extended, it is preferable that the link arm 5 be bent in a substantially square shape like the shape including the sub arm 6 of FIG.

  Moreover, in the said embodiment, although the torsion winding spring 9 was used, it can replace with the torsion winding spring 9 as an elastic member, and can also use a leaf | plate spring (not shown). In this case, one end (front end) of the leaf spring is fixed to the protector base 2, and the other end (front end) is engaged with the link arm 5.

  Moreover, in the said embodiment, although the guide hole 10 penetrated to the protector base 2 was provided, it can replace with the guide hole 10 as a guide part, and can also provide a guide groove (not shown). In this case, a part (the convex wall 25) of the substrate portion 12 of the protector base 2 is formed thick, a guide groove is formed in the convex wall 25, and a slide engagement portion similar to FIG. 2 is formed in the guide groove. 11 is engaged. However, the guide hole 10 is more advantageous in reducing the thickness of the protector 4.

  If the door inner panel (not shown) of the sliding door has a recess (not shown) for escape, the convex wall 25 can be projected outside the protector 4 instead of inside the protector 4. It is also possible to provide the guide hole 10 and the guide groove directly on the thick protector base (12) without providing the convex wall 25. However, in this case, the protector base (12) is weighted.

  Further, the shaft portion 11a of the slide engagement portion 11 may be formed as an arc-shaped rib along the arc-shaped guide hole 10 instead of a circular cross section. However, in this case, the guide hole 10 needs to have an arc shape. It is also possible to always regulate the direction of the harness holding portion 7, that is, the direction in which the wire harness 20 is led out along the guide hole 10 by making the shaft portion 11 a have a rectangular cross section or the like. However, in this case, there is a concern that the sliding property is lowered. Further, the head portion 11b of the slide engagement portion 11 is not necessarily limited to a disc shape, and may be rectangular or hook-like, and the cross-sectional shape of the slide engagement portion 11 including the shaft portion 11a and the head portion 11b is T-shaped. It is not limited to a shape, but may be an L shape. In short, the head portion 11b only needs to hold the shaft portion 11a from the guide hole 10 and hold it in the guide hole.

  Moreover, in the said embodiment, although the protector base 2 and the protector cover 3 comprised the protector 4, since the harness holding | maintenance part 7 of the front end side of the link arm 5 is rotatably hold | maintained at the protector base 2, Even if the protector cover 3 is removed, the position of the wire portion 23 of the wire harness 20 is regulated to some extent along the protector base 2, and the protector cover 3 can be replaced by a synthetic resin sliding door trim 29.

  In the above-described embodiment, the slide engaging portion 11 is provided in the harness holding portion 7. However, the slide engaging portion 11 may be provided on the distal end side or the intermediate portion of the sub arm 6 instead of the harness holding portion 7. is there. In this case, the guide hole 10 is disposed above the example of FIG. 1 (above the skirt 12 'of the protector base 2). When the slide engagement portion 11 is provided on the link arm 5, the guide hole 10 is limited to an arc shape having the same radius, and it is difficult to correspond to the horizontally long protector base 2.

  In the above embodiment, the protector 4 is described as being vertically (vertically placed) with respect to the slide door. However, for example, the protector 4 is horizontally (sideways) placed on the slide door, or the vehicle is not a slide door. It is also possible to arrange the protector 4 horizontally (sideways) on the body side and the harness fixing part 26 on the slide door side. In these cases, it is also possible to arrange the protector base 2 on the upper side and the protector cover 3 on the lower side. The wire harness 20 is absorbed in the horizontal direction by the urging force of the torsion spring 9 in the protector.

  Moreover, in the said embodiment, although the corrugated tube 22 was used as a protective tube of the wire harness 20, it replaced with the corrugated tube 22, and other resin tubes were used or the protective tube 22 was excluded and the electric wire part 23 was taped. It can also be used in a state of being bound by a band or the like. In this case, the harness holding portion 7 is shaped like a bowl, and the resin tube and the electric wire portion 23 can be fixed to the harness holding portion (7) by band fastening or the like.

  The present invention is effective not only as a power supply device for a slide structure but also as a wiring structure for a wire harness for a slide structure.

  The power supply device for a slide structure according to the present invention can be used for constantly supplying power to a slide door or a slide portion in an automobile, a vehicle other than an automobile, a device other than a vehicle, or the like.
