Description

  The present invention is applied to a slide structure such as a slide door of an automobile, and relates to a harness routing structure for a slide structure for constantly supplying power to an auxiliary machine or the like of the slide structure and a power supply apparatus including the same. is there.

  FIG. 8 shows an embodiment of a conventional power supply device for a sliding door (see, for example, Patent Document 1).

  This power supply device 50 is disposed on a sliding door 41 of an automobile, and includes a protector 42 made of a synthetic resin that houses the wire harness 43 in a bendable manner, and a metal leaf spring that urges the wire harness 43 upward in the protector. 44.

  The protector 42 is composed of a protector base (substitute with reference numeral 42) and a protector cover (not shown). The protector base and the protector cover each have a vertical base wall 51 and an outer peripheral peripheral wall 52 that are opposed to each other. Is locked to the protector base by locking means, and the protector base is fixed to the panel of the slide door 41 with bolts 56 and locking clips.

  The lower end portion of the leaf spring 44 is fixed together with the wire harness 43 to the harness fixing portion 55 on the lower front end side of the protector 42, and the distal end side of the leaf spring 44 supports the wire harness 43 so as to be slidable. A synthetic resin cap 49 is attached to the tip of the leaf spring 44, and the wire harness 43 is stably supported by the cap 49.

  The wire harness 43 is configured by covering a plurality of electric wires 43a with a corrugated tube 43b made of synthetic resin, and a front end lower portion of the corrugated tube 43b is fixed to the protector 42 by tape winding or the like. The corrugated tube 43b has concave grooves and ridges alternately and exhibits good flexibility.

  One electric wire portion 43a of the wire harness 43 is led out from the front portion of the protector 42 and connected to an auxiliary machine on the slide door side. The other corrugated tube portion 43 b of the wire harness 43 is routed so as to be swingable from the elongated lower opening 45 of the protector 42 to the harness fixture 53 on the step 48 side of the vehicle body 47 through the transition space (crossover portion). The other electric wire portion (not shown) is connected via a harness fixture 53 to a wire harness (not shown) on the vehicle body side. The protector 42 is covered and hidden by a synthetic resin door trim (not shown), and the wire harness 43 is led out to the vehicle body side from the opening at the lower end of the door trim.

  In the transition space, the electric wire 43a in the wire harness 43 is safely protected from interference with the outside, water droplets, dust, and the like by the corrugated tube 43b having relatively high rigidity and high waterproofness. The harness fixture 53 absorbs the twist when the wire harness 43 swings as the slide door 41 opens and closes.

  The wire harness 43 is pulled backward when the sliding door 41 of FIG. 8 is fully closed, and the wire harness 43 is pulled forward when the sliding door 41 is fully open. In particular, the wire harness 43 is downward when the sliding door 41 is half open. Although it is going to loosen, it is biased upward by the leaf spring 44 to absorb the slack (extra length) and prevent pinching due to drooping.

  In addition to the configuration shown in FIG. 8, Patent Document 1 discloses that a separate metal guide rail is horizontally provided at the lower end of the synthetic resin protector on the sliding door side, and the slider is slidably engaged with the guide rail. And a power feeding device (not shown) having a structure in which the wire harness is routed to the vehicle body side through the crossing portion while holding the wire harness in the protector on the upper and lower swing arms of the slider. Yes.

  FIG. 9 shows another embodiment of a conventional power supply device for a sliding door (see Patent Document 2).

  The power supply device 61 for the sliding door includes a horizontally long case 63 provided on the left sliding door 62 of the automobile, a slider 64 slidably engaged with a guide rail (not shown) in the case, and a slider 64. A swinging member 65 that is supported by a shaft portion perpendicular to the shaft so as to be swingable in a horizontal direction, and is bent and arranged in a substantially U shape inside the case 63, and is arranged from the swinging member 65 to a vehicle body (not shown). ) And a caterpillar-shaped harness exterior member 66 arranged so as to be bent freely.

  The exterior member 66 is covered with a tube 67 between the slide door 62 and the vehicle body (crossover portion). A plurality of electric wires (wire harnesses) 68 are inserted inside the exterior member 66 and the slider 64.

By opening the sliding door 62 in the arrow A direction (rear of the vehicle) from the state of FIG. 9, the slider 64 moves relative to the front along the case 63, and the wire harness 68 and the exterior member 66 are approximately Extends in a letter shape. When the sliding door 62 is opened and closed, the wire harness 68 expands and contracts together with the exterior member 66, so that the harness surplus length is absorbed.

  However, in the power feeding device 50 (FIG. 8) described in Patent Document 1, the height of the door is obtained because the extra length of the wire harness is absorbed by the leaf spring in the height direction of the slide door. It tends to occupy space in the direction, and in vehicles with a large sliding door stroke amount, the size of the protector and harness routing structure in the height direction cannot be denied. In addition, since a metal leaf spring is used, there is a problem that the cost is increased.

  Further, in the other power feeding device (not shown) described in Patent Document 1, the structure of the slider portion is complicated, and the guide rail is made of metal that is separate from the protector. In addition, when the sliding resistance between the guide rail and the slider is large, there is a concern that the opening operability of the sliding door is deteriorated. Further, in the power supply device 61 (FIG. 9) described in Patent Document 2, since a caterpillar-shaped exterior member is used even in the horizontally long case 63, the cost is increased, and the wire harness is used in the slider 64. There is a concern that the wire harness 68 is easily damaged because the 68 is bent in a corrective manner.

  These problems may also occur when each of the power supply devices described above is applied to a slide structure such as a slide door of a vehicle other than an automobile, a slide door of a machine tool, or the like instead of the automobile slide door.

In view of the above-described points, the present invention can be used for a slide structure in which a wire harness can be routed in a small space in the height direction of the slide structure, and the structure can be made compact in the height direction. A first object is to provide a harness wiring structure and a power supply device including the same. In addition, the second object is to reduce the cost by reducing the number of parts and to improve the operability when the slide structure is opened.

The power feeding device 1 in the fully closed state of the sliding door is indicated by a chain line on the left side, and the power feeding device 1 in the fully opened state is indicated by a solid line on the right side. 1-3, the sliding door opens and closes in the front-rear direction, the left side in the figure is the rear side of the vehicle, the right side in the figure is the front side of the vehicle, the sliding door in FIG. 4 is closed to the front side in the figure, Open to the other side.

This power supply device 1 includes a rectangular protector 2 made of a synthetic resin that is arranged vertically (vertically placed) on a door inner panel of a sliding door and fixed with bolts or the like, and a wire harness 3 is installed in the protector from the upper rear side. Introduced and routed in an upward curved shape, a guide groove as a guide rail (guide portion) 4 is integrally provided in the lower front half of the protector 2, and a curved portion (curved harness portion) 5 of the wire harness 3 is provided. The front end portion (terminal) 5a is slidably supported on the guide rail 4 via the spherical slider 6, and the wire harness 3 is arranged from the guide rail 4 to the vehicle body (fixed structure) side through the crossing portion (space). It has been searched.

  The protector 2 includes vertical wall portions 7 and 8 on the left and right sides (front side and rear side) in the vehicle width direction, peripheral wall portions 9 to 11 that connect the wall portions 7 and 8 at the front and rear sides, and the upper side, and a lower harness lead-out. And the front wall portion 7 is formed shorter at the lower end side than the rear wall portion 8, the opening 12 is located at the lower end of the front wall portion 7, The lower end of each of the wall portions 7 and 8 on the back side is inclined in the latter half (the inclined side portion is indicated by reference numeral 13 in FIG. 2), and the guide rail 4 is opposed to each of the wall portions 7 and 8 on the front side and the back side. It is formed linearly by integral resin molding.

  The front wall portion 7 is resin-molded separately from the base which is the rear wall portion 8 as a cover, and is joined to each other by locking means and fixing means via the peripheral wall portions 9 to 11. The opening edge 7a of the wall 7 on the front side is curved outward, and the wire harness 3 is bent without difficulty along the opening edge 7a toward the vehicle body.

  The wire harness 3 is introduced obliquely rearward and downward from the hole 14 of the upper wall, which is the horizontal peripheral wall portion 11 on the upper side of the protector 2, and is folded obliquely forward and upward between the upper wall 11 and the middle of the protector 2 in the height direction. As a result, the curved portion 5 continues to the guide rail 4, and continues to the vehicle body side through the opening 12 while being routed downward from the guide rail 4. The diagonally downward harness portion 15 and the folded harness portion 5b are arranged along a substantially J-shaped inclined guide wall 16 and are fixed to the guide wall 16 and the rear side by a fixing means (fixing portion) 17 such as a band. It is fixed to the wall 8. The diagonally downward harness portion 15 follows a harness portion (not shown) led out to the outside of the protector 2, and the led harness portion is connected to an auxiliary device such as an electrical component on the slide door side.

  The upper half of the protector 2 is formed thinner than the lower half, and a guide rail 4 is provided in the lower half, and a spherical slider 6 is slidably engaged with a pair of opposed guide rails 4, The wire harness 3 is routed through the slider 6. A slider 6 is arranged on the outer periphery of the wire harness 3 so as to be fixed or rotatable in the circumferential direction. The slider 6 is formed to be separable by, for example, synthetic resin, and a rib (not shown) that engages with a concave groove (not shown) of the corrugated tube 18 on the outer periphery of the wire harness 3 is formed on the inner peripheral surface of the harness insertion hole 6a. Have.

  The length of the guide rail 4 is set as short as about half of the length from the front end (terminal) 6a of the curved portion 5 of the wire harness 3 to the rear end 5b when the slide door is fully opened. The front end 4 a of the guide rail 4 is positioned near the lower end of the front wall 9 of the protector 2. The rear end 4b of the guide rail 4 is located at substantially the same height as the harness support (harness support part) 19 on the vehicle body side.

  Since the guide rail 4 is disposed obliquely downward from the rear end 4b to the front end 4a, the wire harness 3 has a space in the diagonal direction (from the upper left to the lower right) of the protector 2 when the sliding door of FIGS. The extra length absorption capability (expansion of the extra harness length) of the wire harness 3 is enhanced in a limited space.

  Further, when the slide door is manually opened by the occupant, the slider 6 is lowered by its own weight along the guide rail 4, so that the slider 6 is smoothly slid with a small force, and the slide door opening operability is improved. Since the closing operation of the sliding door is not performed manually by the occupant but by a motor drive, there is no occupant burden.

  The guide rail 4 is formed by bulging the wall portions 7 and 8 on the front side and the back side of the protector 2 outward. A slit 20 (FIG. 2) is provided at the center in the width direction of the guide rail 4. The bulging wall (groove wall) 21 which is the peripheral edge of the slider can be elastically bent in the plate thickness direction, and the sliding property of the slider 6 is enhanced (the slider 6 is smooth in the guide rail with a small sliding resistance). To go to).

  The wire harness portions 5 and 15 in the protector are configured to have a small diameter by roughly winding a plurality of insulation-coated electric wires from the upper wall 11 of the protector 2 to the slider 6 with a binding means such as a vinyl tape or a band. A wire harness portion (represented by reference numeral 18) over the harness fixture 19 on the body side is configured by covering a plurality of insulating coated electric wires with a protective tube 18 such as a flexible corrugated tube made of synthetic resin. By not covering the wire harness 3 with the protective tube in the protector 2, the protector 2 (especially the upper half without the slider 6) is made thin.

  The corrugated tube 18 has a circular cross section in which circumferential grooves and ridges are alternately arranged in the longitudinal direction of the tube. A protective tube such as a mesh tube can be used instead of the corrugated tube.

  A harness fixture 19 on the vehicle body side is a synthetic resin split clamp that holds the corrugated tube 18 immovably, and a rib that engages with a concave groove (not shown) of the corrugated tube 18 on the outer periphery of the wire harness 3. (Not shown) is provided on the inner peripheral surface of the corrugated tube insertion hole. Since the rotation of the corrugated tube 18 in the circumferential direction is received by the slider 6 on the protector 2 side, the harness fixture 19 on the vehicle body side does not need to rotate the corrugated tube 18 in the circumferential direction, and the existing inner clamp (inside the outer clamp) Thus, the inner clamp is rotatably arranged and the conventional structure for fixing the corrugated tube to the inner clamp is not required, and the harness fixture 19 is miniaturized. The plurality of electric wire portions 22 of the wire harness 3 are led out from the harness fixture 19 into the vehicle body.

  As shown in FIGS. 1 and 2, when the sliding door is fully opened (in the protector 2 on the left side in the figure), the wire harness 3 is extended back and forth while curving upward in a low mountain shape with a large radius. The height (for example, the vertical distance from the slider 6 to the curved top 5c) can be kept low. The slider 6 is located at the front end 4 a of the guide rail 4. The length of the imaginary straight line connecting the slider 6 and the fixed portion 17 is several times longer than the height from the imaginary straight line to the curved top 5c, and the curved portion 5 close to a flat shape is formed. The protector 2 is made compact (low profile) in the height direction by arranging the curved portion 5 of the wire harness 3 in a flat shape in the protector.

  In FIG. 2, the harness portion 18 in front of the slider 6 is positioned slightly downward from the horizontal in the crossover portion 23 (FIG. 4) while being pulled forward with the harness support 19 as a fulcrum (see FIG. 4). When the slide door is fully opened, the protector 2 is separated from the vehicle body together with the slide door (see FIGS. 3 to 4), and the harness portion 18 of the crossover 23 is seen in plan view from the protector 2 to the harness fixture 19 as shown in FIG. Pulled diagonally forward.

  Further, when the sliding door is fully closed (in the right protector 2 in FIG. 2), the wire harness 3 is bent (bent) in a shape close to a loop shape with a small radius, and is pulled rearward over the harness fixture 19 to be horizontal. To position. The top portion 5c of the substantially loop-shaped (substantially horizontal U-shaped) curved portion 5 is rotated upward with the lower fixing portion 17 as a fulcrum, and is positioned higher than when the slide door is fully opened (left protector in the figure). . The slider 6 is located at the rear end 4b of the guide rail 4, and the height of the slider 6 and the harness fixture 19 is substantially equal. As shown in FIG. 2, the harness portion 18 from the slider 6 to the harness supporter 19 is horizontal without dropping. Located at the shortest distance.

  Since the harness portion 18 does not hang down, the harness portion 18 is reliably prevented from being caught between the sliding door and the vehicle body, and the harness portion 18 is positioned at the shortest distance so that the harness portion 18 is shortened and reduced. Cost is increased. Within the protector, the wire harness 3 is accommodated in a substantially loop shape and is absorbed by the extra length.

  As shown in FIG. 2, the length of the bending portion 5 in the protector (the length of the harness from the fixing portion 17 to the slider 6) does not change between when the slide door is fully closed and when it is fully open. Similarly, the length of the harness portion 18 from the slider 6 to the harness support 19 does not change.

  By moving the slider 6 along the guide rail 4, the wire harness 3 is pulled out from the lower part of the front end of the protector 2 to the harness support 19 in the vicinity of the front end 4 a of the guide rail 4 when the slide door is fully opened. When fully closed, the wire harness 3 passes through the protector 2 from the rear end 4b of the guide rail 4 in the horizontal direction, and is pulled out from the rear end of the protector 2 to the harness supporter 19.

  The bending portion 5 of the wire harness 3 in the protector changes smoothly from a low mountain shape to a substantially loop shape as the slider 6 moves, so that the sliding door can be opened and closed with the harness support 19 as the center. Can be supported.

  As shown in FIG. 2, when the sliding door is fully closed (in the right protector 2 in the figure), the bending center point of the substantially loop-shaped bending portion (bending portion) 5 of the wire harness 3 in the vicinity of the upper side of the slider 6 in the protector. Is located. The fixing portion 17 of the wire harness 3 is located in the upper half of the protector 2, and the horizontal harness portion 18 toward the slider 6 and the harness fixture 19 is located in the lower half of the protector 2. A gap 24 about the radius of the substantially loop-shaped curved portion 5 is vacated between the fixed portion 17 and the horizontal harness portion 18. The wire harness 3 in the protector is extended in the door opening / closing direction (front-rear direction) when the sliding door is fully closed, and is shortened in the door opening / closing direction when the sliding door is fully opened. As the sliding door is opened and closed, the wire harness 3 expands and contracts in the door opening and closing direction in the protector.

  As shown in FIG. 3, the length of the harness portion 18 led out from the right protector 2 to the harness fixture 19 when the sliding door is fully closed is longer than the length of the left harness portion 18 when the sliding door is fully opened. Short, the harness portion 18 is led out from the protector 2 to the rear almost straight.

  In the half-opened state of the sliding door, the slider 6 is positioned approximately in the center in the longitudinal direction of the guide rail 4 in FIG. 2, and the slider 6 and the harness support 19 are positioned so as to face each other in the left and right direction (vehicle width direction). The bending portion 5 of the wire harness 3 has an intermediate diameter, that is, a diameter approximately in the middle between the bending radius of the bending portion 5 when the left sliding door is fully opened in the drawing and the bending radius of the bending portion 5 when the right sliding door is fully closed in the drawing. It becomes.

  5 to 7 show another embodiment of a harness routing structure for a slide structure according to the present invention and a power feeding apparatus including the harness routing structure.

  As shown in FIG. 5, the harness routing structure and the power feeding device 1 ′ of this embodiment are obtained by changing the slider and the guide portion in the embodiment of FIG. 1, and other configurations are the same as those of the embodiment of FIG. 1. Components similar to those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 6 and 7, the slider 6 ′ of this embodiment is formed of a synthetic resin in a rectangular cylindrical shape, and a pair of short cylindrical shaft portions 26 are horizontally provided on the outer surfaces of the left and right side walls 25. Configured. Each shaft portion 26 is slidably engaged with a long-hole-shaped slit portion 20 ′ serving as a guide portion between a protector base (represented by reference numeral 8) and a protector cover (represented by reference numeral 7) of the protector 2 ′. .

  The left and right side walls 25 of the slider 6 'are formed wide, and the upper and lower wall parts 27 (up and down when the door is closed) are formed narrow. The shaft portion 26 is disposed near the base ends of the side walls 25, and a synthetic resin-made corrugated tube 18 'made of synthetic resin is led out from the base end of the slider 6' to the vehicle body side as a harness protection tube. ing.

  The slider 6 'is formed into a left and right divided type, and a rib (not shown) that engages with a circumferential groove 18a (FIG. 7) of the corrugated tube 18' is formed on the inner circumferential surface of the slider 6 '. Projected. The wire portion 5 of the wire harness 3 ′ is led out into the protector 2 ′ from a rectangular opening (harness insertion hole) 28 at the tip of the slider 6 ′. The electric wire part 5 is covered and converged by tape winding or a net-like flexible protective tube (not shown). In FIG. 6, the left and right divided sliders are fixed to each other by a locking projection 29 as a locking means and a flexible locking frame piece 30 on the upper and lower wall portions 27. A dividing surface of the slider 6 'is denoted by reference numeral 31 in FIG.

  The slit portion 20 'is formed on each vertical substrate portion (the back wall 8 and the front wall 7) of the protector base and the protector cover so as to be inclined downward in the same manner as the guide rail 4 in FIG. The length and position of the slit portion 20 'are substantially equal to the length of the guide rail 4 in FIG. The protector 2 'in FIG. 5 is thinned by the absence of the guide rail 4 bulging outward in FIG.

  The twist of the corrugated tube portion 18 'when the sliding door is opened and closed is absorbed by the rotation of the inner member (not shown) of the harness fixture 19' on the vehicle body side. This point is different from the case of the slider 6 of FIG. 1 (the slider 6 of FIG. 1 rotates freely, so that an inner member is not required for the harness fixture 19 on the vehicle body side). Note that this is not the case when the slider 6 of FIG. 1 is provided with the shaft portion (26) and the shaft portion (26) is slidably engaged with the slit portion 20 of the guide rail 4.

  The slider 6 ′ is slidable along the slit portion 20 ′ by the shaft portion 26, and is rotatable (swinged) in the circumferential direction of the shaft portion. Needless to say, since the slider 6 'has a rectangular shape, the slider 6' cannot rotate in the harness circumferential direction.

  In FIG. 5, when the sliding door is fully opened, the slider 6 ′ is inclined slightly rearward from the vertical on the front end 20a side of the slit portion 20 ′, and the wire harness 3 ′ extends in a low mountain shape, as shown on the left side. When the sliding door is fully closed, the slider 6 'is largely inclined forward on the rear end 20b side of the slit portion 20', and the wire harness 3 'contracts in a substantially loop shape as shown in the drawing on the right side.

  In each of the above embodiments, the wire harnesses 3 and 3 ′ are retractably accommodated by using the protectors 2 and 2 ′. However, for example, the protectors 2 and 2 ′ are eliminated, and the guide portions 4 and 20 ′ are replaced with the slide door. The wire harnesses 3 and 3 'are arranged in a curved shape upward in the same manner as in FIG. 2 along the vertical surface of the door inner panel, and can be slid with a slider to the guide portions 4 and 20'. It is also possible to engage.

  Moreover, it is also possible to make it the long groove which does not penetrate rather than the slit part 20 'which penetrated the guide part of FIG. Further, instead of the door inner panel, guide portions 4 and 20 ′ are provided on the inner surface of the synthetic resin door trim, and the wire harnesses 3 and 3 ′ are arranged in an upward curved shape along the inner surface of the door trim in the same manner as in FIG. It is also possible to search.

  1 and 5 can be formed by press molding on a metal door inner panel, or can be integrally molded with a synthetic resin door trim. Further, a pair of guide portions 4 and 20 'are opposed to the door inner panel and the door trim and formed by press molding or resin molding, and the door inner panel guide portions 4 and 20' and the door trim guide portions 4 and 20 'are formed. A spherical slider 6 may be arranged so as to be slidable in a one-dimensional direction and rotatable in a three-dimensional direction, or a rectangular slider 6 ′ may be arranged so as to be slidable in a one-dimensional direction and rotatable in a two-dimensional direction. Is possible.

  Moreover, in each said embodiment, although the wire harnesses 3 and 3 'were introduced into the protector from the upper direction, depending on arrangement | positioning etc. of the wire harnesses 3 and 3' by the side of a door, the wire harnesses 3 and 3 'are protected. , 2 'can be introduced through holes (not shown) in the rear wall 10 and the back wall 8. Also in these cases, it is preferable that the fixing portions 17 of the wire harnesses 3 and 3 ′ are located in the upper rear half of the protectors 2 and 2 ′.

  In each of the above embodiments, the guide portions 4 and 20 ′ are disposed obliquely upward from the front ends 4a and 20a to the rear ends 4b and 20b. For example, the rear ends 4b and 20b of the guide portions 4 and 20 ′ are fixed to the harness. If the height with the tool 19 is comparable, it is also possible to arrange | position guide part 4,20 'horizontally. Further, it is possible to incline the guide portions 4 and 20 ′ in a downward curved shape instead of linearly inclining.

  In the above embodiments, the guide portions 4 and 20 'are formed on the protector 2 by integral resin molding. However, a separate synthetic resin or metal guide portion may be provided in the protector instead of being integral. is there. In this case, the shape of the guide portions 4 and 20 ′ is not limited to the guide groove shape and the through slit shape, and various shapes such as an L-shaped section and a T-shape can be set as necessary. The number is not limited to a pair opposed to each other, and may be only one.

  In each of the above embodiments, the wire harnesses 3 and 3 ′ are curved upward in the protector. For example, the harness support 19 may be arranged on the upper side of the sliding door instead of the lower side. 2 is configured such that the wire harnesses 3 and 3 ′ are bent downward in the protector as in the case of turning upside down in FIG. 2, and the guide portions 4 and 20 ′ are arranged on the upper side rather than the lower side of the bending portion 5 of the wire harness. It is also possible to do.

  Moreover, although each said embodiment showed the example applied to the slide door of a motor vehicle, it replaced with the slide door of a motor vehicle, slide doors other than a motor vehicle, etc., slides other than a slide door and a slide door of machine tools, and an inspection device. It is also possible to apply the harness wiring structure and the power feeding device to the structure. The sliding door is generically referred to as a sliding structure, and the vehicle body, machine tool main body, inspection apparatus main body, and the like are generically referred to as a fixed structure.
