  However, in the conventional power feeding device 51 of FIG. 10, there is a problem that the number of parts and the weight increase due to the long guide rail 53 and the links 55 and 56, and a long wire harness 57 is provided along the long links 55 and 56. When the wire harness 57 is bent to a small diameter at the intersection of the slider portion 54 and the links 55 and 56 and the bending stress is increased, or when the sliding door 52 is vigorously opened, the wire harness 57 is mounted on the vehicle. Concerns that the durability of the wire harness 57 may decrease due to interference with the body 58, or that the open / close operability of the slide door 52 may decrease due to an increase in frictional resistance between the guide rail 53 and the slider 54, for example. was there. Further, in the power supply device 62 of FIG. 11 described above, there is a concern that the wire harness 66 may be bent in a complicated (zigzag) manner with the rotation of each link 65 and the durability of the wire harness 66 may be lowered. .

  These problems and concerns can occur in the same way when each power feeding device is applied to a sliding structure such as a sliding door of a train door, a manufacturing device, a detection device, etc. It is. In this case, the vehicle body, the apparatus main body, and the like are collectively referred to as a fixed structure.

  In view of the above points, the present invention eliminates the enlargement and weight of the structure and the length of the wire harness and can be arranged in a space-saving manner at a low cost, and also reduces the bending stress of the wire harness. To provide a power feeding device for a slide structure that can prevent the interference between the wire harness and the vehicle body, increase the durability of the wire harness, and improve the opening / closing operability of the slide structure With the goal.

In order to achieve the above object, in the power supply device for a slide structure according to claim 1 of the present invention, a plurality of links are rotatably connected in series, and a base-side link is vertically connected to the slide structure. biased upward by the elastic member while being rotatably connected to a base member disposed on every other, the harness holding portion is provided on the distal end side of the link, the protection tube of the wire harness in the harness holding portion is fixed while of the wire harness is routed in the sliding structure along the base member from the harness holding portion, the other of the wire harness is routed in the fixed structure from the harness holding portion, the base end side The link on the distal end side is rotated downward and bent with respect to the link, and the harness holding portion is arranged eccentrically outward in the bending direction with respect to the link on the distal end side .

With the above configuration, for example, when the number of links is two, the distal end of the distal link is a free end, and the proximal end of the distal link is rotatably connected to the distal end of the proximal link The base end portion of the base end side link is rotatably connected to the base member. The base member is placed vertically on the slide structure, and when the slide structure is fully closed, each link is pulled backward together with the wire harness toward the harness fixing part on the fixed structure side, and when the slide structure is fully opened, each link is Bending while turning forward toward the harness fixing part on the fixed structure side with each connecting part as a fulcrum (the link on the distal end rotates at a larger angle than the link on the proximal end) The wire harness is led out from the harness holding part to the harness fixing part. The wire harness can be bent with the tip of the harness holding portion as a fulcrum.
In addition, for example, when each link is bent inward from the connecting portion when the slide structure is fully opened, the harness holding portion is positioned outside the bending, so that the bending radius of the wire harness along each link from the harness holding portion is large. The bending stress applied to the wire harness is reduced.

  A power supply device for a slide structure according to a second aspect is the power supply device for the slide structure according to the first aspect, wherein the number of the links is three or more.

  With the above configuration, for example, when the number of links is three, the proximal end of the distal link is pivotally connected to the distal end of the intermediate link, and the proximal end of the intermediate link is connected to the proximal end. It is rotatably connected to the tip of the link. When the slide structure is fully opened, the state-of-the-art link rotates at a larger angle than the intermediate link, and the intermediate link rotates at a larger rotation than the proximal end side link. As the number of links increases, the length of the entire link becomes longer, the position of the harness holding part when the slide structure is fully opened approaches the harness fixing part on the fixed structure side, and the wire from the harness holding part to the fixed structure side The length of the harness is shortened, the harness protection tube (especially the corrugated tube) is shortened, and the rigidity is reduced.

  The power supply device for the slide structure according to claim 3 is the power supply device for the slide structure according to claim 1 or 2, wherein the harness holding portion is disposed at the most distal portion of the link on the distal end side. Features.

  By the said structure, the length of the wire harness (harness protection tube) from a harness holding part to the fixed structure side is further shortened.

  The power supply device for a slide structure according to a fourth aspect is the power supply device for the slide structure according to the first or second aspect, wherein the harness holding part is extended in the harness longitudinal direction from the link on the distal end side. The protective tube is fixed to the extended portion.

  With the above configuration, the position of the harness holding portion when the slide structure is fully opened is further brought closer to the harness fixing portion on the fixed structure side by the extended portion of the harness holding portion, and the length of the wire harness from the harness holding portion to the fixed structure side The harness protection tube (especially the corrugated tube) is further shortened and the rigidity is lowered.

  The power supply device for a slide structure according to a fifth aspect is the power supply device for the slide structure according to any one of the first to fourth aspects, wherein the link on the distal end side is connected to the link on the near side by a ball joint. It is characterized by that.

  With the above configuration, when a force in the link thickness (base member thickness direction) direction acts on the harness holding part due to tension, compression, or twisting of the wire harness when the slide structure is opened or closed, the harness holding part is a ball joint. It rotates (swings) in the thickness direction of the link to absorb the force, reduces the bending stress of the wire harness, and smoothly bends.

According to the first aspect of the present invention, the structure without using the guide rail of the related art not only makes the structure compact, space-saving and lightweight, but also when the slide structure is opened and closed. By turning and bending in the direction, the wire harness is smoothly bent with a large radius in one direction, the bending stress applied to the wire harness is reduced, and the durability of the wire harness is improved.
Further, for example, when each link is bent while the wire harness is pulled when the slide structure is fully opened, the bending radius of the wire harness along each link from the harness holding portion is specified to be large, and the bending stress applied to the wire harness is reduced. Thus, the durability of the wire harness is improved.

  According to the second aspect of the present invention, since three or more links are smoothly rotated and bent in the same direction to bend the wire harness more smoothly and with a small bending stress, the durability of the wire harness is further increased. improves. Also, by using three or more links to increase the length of the entire link, the length of the wire harness from the harness holding portion to the fixed structure, for example, is shortened, and the wire harness and the fixed structure Interference is prevented by increasing the gap between them, and the protective tube of the wire harness from the harness holding part to, for example, the fixed structure is shortened, so that the cost is reduced and the rigidity of the protective tube is reduced. The opening / closing operation force of the slide structure is reduced, and the opening / closing operability is enhanced.

  According to the invention of claim 3, the length of the wire harness from the harness holding part to, for example, the fixed structure is further shortened, the gap between the wire harness and the fixed structure is increased, and interference is further prevented. Since the protective tube is further shortened and has low rigidity, the cost can be further reduced and the opening / closing operability of the slide structure is enhanced.

  According to invention of Claim 4, the length of the wire harness from a harness holding part to a fixed structure is further shortened by the extension part of a harness holding part, for example, and the clearance gap between a wire harness and a fixed structure is made. Further, interference is further prevented, and the protective tube is further shortened and has low rigidity, so that the cost is further reduced and the opening / closing operability of the slide structure is enhanced.

  According to the fifth aspect of the present invention, when a force in the link thickness direction acts on the harness holding portion due to the tension of the wire harness when the slide structure is opened and closed, the ball joint absorbs an excessive bending stress of the wire harness. Thereby, while improving durability of a wire harness, the opening / closing operation | movement of a slide structure can be performed smoothly with low power.

In this case, the protector base 2 is replaced with a slide door panel or the like, and the plate wall (base member) 16 is fixed to the slide door panel.

  In the embodiment of FIG. 1, the wire harness 13 is introduced downward from the harness outlet 13 along the protector base 2, bent backward, and then bent upward, while the first link 4 is substantially S-shaped. It passes through the side of the second link 5 from the front end side substantially in parallel, and is inserted into a synthetic resin corrugated tube 12 on the harness holding portion 7 side of the third link 6. The corrugated tube 12 is an existing bellows-like harness protection tube with good flexibility, in which circumferential grooves and ridges (not shown) are alternately arranged in the longitudinal direction of the tube.

  The embodiment of FIG. 1 is characterized in that the harness holding portion 7 is provided on the link 6 on the tip (free end) side using three links 4 to 6. The harness holding portion 7 is disposed at the most distal end portion of the link 6 on the distal end side. A configuration using two links 4 'and 6 has been previously proposed by the present applicant in Japanese Patent Application No. 2007-233863. The configuration is shown in FIG. 3 for reference. The number of links is not limited to three but can be more. In any case, the harness holding portion 7 is provided at the most distal portion of the most advanced link 6.

  The first link 4 has a base end (front end) portion rotatably connected to the plate wall 16 by the shaft portion 3 and is biased upward by a torsion spring 8 between the first link 4 and the plate wall 16. The winding portion 8a of the spring 8 is located around the shaft portion 3, one end of the spring 8 is supported by the protrusion 18 of the plate wall 16, and the other end of the spring 8 is supported by the upper protrusion 19 of the first link 4. Has been. In the present embodiment, the front / rear and up / down directions are made to coincide with the direction of the vehicle.

  The second link 5 is rotatably connected to the distal end portion of the first link 4 by the second shaft portion 20, and the third link 6 is connected to the distal end portion of the second link 5 by the third shaft portion 21. Are rotatably connected. The first link 4 and the third link 6 are located on the same vertical plane, and the second link 5 is located closer to the surface of the protector base 2 than the first link 4. 6 is rotatable along the substrate portion 9 of the protector base 2.

  In FIG. 1 of the third link 6, the harness holding part 7 is arranged eccentrically (offset) on the upper side of the link 6, that is, outside the link 6 in the bending direction. Bending refers to the bending form of each link 4-6 in FIG. The links 4 to 6 and the harness holding part 7 constitute a link assembly. It can also be considered that the third link 6 is constituted by a plate-like link main body 6 a and a harness holding portion 7.

  The harness holding part 7 is composed of a plate-like base 7a and a cover 7b fixed to each other by a locking means, and the base 7a is slidable along the surface of the protector base 2 or has a slight gap. It is located in parallel and is fixed by sandwiching one end of the corrugated tube 12 of the wire harness 10 between the cover 7b. Ribs that engage with the concave grooves of the corrugated tube 12 protrude from the inner surfaces of the cover 7b and the base 7a. The other end of the corrugated tube 12 is held by a harness support 22 (FIG. 4) on the vehicle body side.

  The electric wire portion 11 led upward from the corrugated tube 12 is fixed to the hole 26 of the base 7a with a band or the like. The electric wire portion 11 is routed to the harness outlet 13 at the front end of the protector while being smoothly bent through the back side or the front side of each link 4 to 6 without being fixed to each link 4 to 6.

  FIG. 2 shows a second embodiment of a power feeding device for a slide structure according to the present invention.

  This power supply device 1 ′ uses the first and second links 4 ′ and 6 to extend the harness holding portion 7 ′ on the tip (free end) side of the second link 6 and project it. It is a feature. Since the other configuration is the same as the proposed configuration in FIG. 3, the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  The harness holding portion 7 ′ in FIG. 2 has an extended portion 24 that protrudes longer in the link longitudinal direction than the power feeding device 1, 1 ″ harness holding portion 7 in FIGS. 1 and 3, and a corrugated inner surface of the extended portion 24. A rib is formed to engage with the concave groove of the tube 12. The length from the proximal end of the first link 4 'to the distal end of the extension portion 24 is from the proximal end of the first link 4 of FIG. It is substantially the same as the length to the front end of the holding part 7, and is set longer than the length from the base end of the first link 4 ′ in FIG. 3 to the front end of the harness holding part 7.

  The first link 4 'shown in FIGS. 2 and 3 has a tip portion 4a bent downward, and a plate-like extension bearing 25 is integrally formed at the tip portion 4a. The extension bearing 25 is a first link. 4 (link body) 4 'is located closer to the protector base 2, and the extension bearing 25 is connected to the second link 6 by the shaft portion 21 on the same vertical plane as the first link 4'. ing.

  4 to 6 show the operation in the embodiments of FIGS. 1 to 3, respectively. In addition, FIG. 7 simply shows the state when the sliding door is fully closed (right side figure), half-opened (middle figure), and fully opened (left side figure) in the power feeding device 1 ″ of FIG. 3 for reference. It is shown.

  In FIG. 7, the code | symbol 22 has shown the harness fixing tool (harness fixing | fixed part) by the side of a vehicle body. 1 to 3 show a state when the sliding door is fully closed, and FIGS. 4 to 6 show a state where the sliding door is fully opened or almost fully opened, respectively. 4-6, the code | symbol 22 has shown the harness fixing tool by the side of a vehicle body, and 15 has shown the harness guide, respectively.

  When the door of FIG. 1 is closed, the corrugated tube portion 12 of the wire harness 10 is pulled rearward toward the harness fixture 22 (FIG. 4) on the vehicle body side against the bias of the torsion spring 8, and each link 4 -6 are located in the shape of "<" or almost straight (not shown). When the sliding door is slid rearward, the wire harness 10 tries to hang down between the vehicle body (crossover part), but is biased upward by the force of the torsion spring 8 to absorb the excess length ( (See the middle diagram in FIG. 7).

  When the door of FIG. 4 is fully opened, the corrugated tube portion 12 of the wire harness 10 is pulled forward toward the harness fixture 22 against the bias of the torsion spring 8 (FIG. 1), and each link 4-6 is stepped. The harness holding portion 7 of the third link 6 is directed in the direction of 90 degrees (obliquely forward) with respect to the downward first link 4. The harness holding part 7 projects outward from the front end lower part 14 of the protector base 2. In FIG. 4, reference numeral 29 is an upper stopper for the first link 4.

  In the embodiment of FIG. 4, the link length is extended by adding the second link 5 as compared to the example of FIG. 6 (FIG. 3) (the position of the harness holding portion 7 is disposed forward). The length of the corrugated tube 12 is shortened. Thereby, the cost of the wire harness 10 is reduced, the rigidity of the corrugated tube 12 is reduced, and the opening / closing operation force of the slide door is reduced.

  Further, since the corrugated tube portion 12 bends by its own weight or the like with the tip 7c of the harness holding portion 7 as a fulcrum, the corrugated tube portion 12 is a vehicle compared to the case where the tip position 7c of the harness holding portion 7 in FIG. It is difficult to bend toward the body, and a large gap 27 is ensured between the vehicle body 28 and the corrugated tube portion 12. Thereby, interference with the vehicle body 28 and the corrugated tube part 12 is prevented.

  Further, by using the three links 4 to 6, the links 4 to 6 when the door is fully opened tend to bend upward largely as compared with the example of FIG. 6, which also causes the vehicle body 28 and the corrugated tube portion 12 to be bent. A large gap 27 is ensured between the vehicle body 28 and the corrugated tube portion 12, which is reliably prevented from interfering with each other. The outline of the vehicle body 28 is shown in plan view. The harness fixture 22 is located in the vicinity of the entrance / exit step (not shown).

  Further, the harness holding portion 7 is arranged eccentrically outward from the shaft portion 21 of the third link 6, and the harness holding portion 7 is positioned below the third link (link main body) 6 in FIG. 4. Thus, since the wire portion 12 of the wire harness 10 is smoothly bent with a large bending radius between the harness holding portion 7 and the harness outlet 13 along the links 4 to 6, the bending stress applied to the wire portion 11 is reduced. As a result, the durability of the electric wire portion 11 is increased.

  In the embodiment of FIG. 5, when the door of FIG. 2 is closed, the corrugated tube portion 12 of the wire harness 10 is rearward toward the harness fixture 22 on the vehicle body side against the bias of the torsion spring 8 (FIG. 2). The links 4 'and 6 are positioned in the shape of a "<" or almost straight slope (not shown). When the sliding door is slid rearward, the wire harness 10 tries to hang down between the vehicle body (crossover part), but is biased upward by the force of the torsion spring 8 to absorb the excess length ( (See the middle diagram in FIG. 7).

  When the door of FIG. 5 is fully opened, the corrugated tube portion 12 of the wire harness 10 is pulled forward toward the harness fixture 22 against the bias of the torsion spring 8, and the first link 4 ′ rotates substantially downward. Then, the second link 6 rotates slightly downward together with the harness holding portion 7 ′, and the harness holding portion 7 ′ and its extended portion 24 protrude slightly diagonally downward from the lower front end of the protector base 2.

  In the embodiment of FIG. 5, compared to the example of FIG. 6 (FIG. 3), the link length is extended by adding the hard extension portion 24 to the harness holding portion 7 ′ (position of the harness holding portion 7 ′). The corrugated tube 12 is reduced in length. Thereby, the cost of the wire harness 10 is reduced, the rigidity of the corrugated tube 12 is reduced, and the opening / closing operation force of the slide door is reduced.

  Further, since the corrugated tube portion 12 is bent by its own weight or the like with the tip 24a of the extension portion 24 of the harness holding portion 7 ′ as a fulcrum, the corrugated portion is compared with the case where the tip position 7c of the harness holding portion 7 in FIG. The tube portion 12 is not easily bent toward the vehicle body 28, and a large gap 27 between the vehicle body 28 and the corrugated tube portion 12 is ensured. Thereby, interference with the vehicle body 28 and the corrugated tube part 12 is prevented. The outline of the vehicle body 28 is shown in plan view.

  Further, in FIG. 5, the harness holding portion 7 ′ is arranged eccentrically outward from the shaft portion 21 of the second link 6, and the harness holding portion 7 ′ is located below the second link (link body) 6. By being positioned, the electric wire portion 11 of the wire harness 10 is smoothly bent with a large bending radius from the harness holding portion 7 ′ to the harness outlet 13 along the links 4 ′ and 6. Such bending stress is reduced and the durability of the electric wire portion 11 is increased. The same applies to the example of FIG.

  In the example of FIG. 7, as the slide door is opened and closed, the second link 6 rotates integrally with the harness holding portion 7 with the shaft portion 21 as a fulcrum at the distal end side of the first link 4. The distance between the harness fixture 22 is always kept to the shortest. Thereby, the length of the wire harness 10 can be set short. Needless to say, this is the same in the embodiment of FIGS.

  FIG. 8 shows one form of the shaft portion 21 that is the connecting portion of the link 6 on the distal end side, and FIG. 9 shows another form of the shaft portion 21 ′ of the link 6 on the distal end side. The tip-side link 6 refers to the third link in the example of FIG. 1 and the second link in the examples of FIGS. The links 5 and 4 'are the front links with respect to the link 6 on the front end side.

  In the example of FIG. 8, a straight pin-shaped shaft portion 21 is used, but in the example of FIG. 9, a ball joint 21 'is used as the shaft portion (connecting portion). The ball joint 21 ′ includes a ball portion 30 and a receiving portion 31 having a circular arc cross section. When force in the link plate thickness direction (vehicle width direction) does not act on the wire harness 10 as shown in FIG. 9A, for example, the second link 5 and the third link 6 including the harness holding portion 7 are Located in parallel.

  As shown in FIGS. 9B and 9C, when a force in the link plate thickness direction acts on the wire harness 10, the third link 6 including the harness holding portion 7 exerts a force on the second link 5. By rotating in the direction, the force applied to the wire harness 10 is absorbed and stress such as bending of the wire harness 10 is reduced. Thereby, the durability of the wire harness 10 is enhanced and the opening / closing operation force of the sliding door is reduced.

  The configuration using the ball joint 21 'has been previously proposed by the present applicant in Japanese Patent Application No. 2007-27710. 8 and 9, the corrugated tube 1 having an oval cross section (flat type) is used, but a corrugated tube (not shown) having a circular cross section can also be used.

  In the embodiment of FIG. 2, the extended portion 24 of the harness holding portion 7 ′ is provided on the second link 6, but the harness holding portion 7 of the third link 6 of the embodiment of FIG. It is also possible to provide the extension part 24 of FIG. 2 in the harness holding part 7 of the four links.

  In each of the above embodiments, the torsion spring 8 is used as the elastic member. However, a plate spring or a compression coil spring can be used instead of the torsion spring 8. It is also possible to eliminate the elastic member 8 and absorb the harness surplus length when the door is half-opened by utilizing the rigidity of the corrugated tube 12.

  Moreover, in each said embodiment, although harness holding | maintenance part 7 and 7 'were eccentrically arrange | positioned on the bending outer side in the link 6 of the front end side, when there is no necessity for the effect of reducing the harness bending stress by this eccentricity, front end side It is also possible to arrange the harness holding portions 7 and 7 ′ coaxially with the link 6.

  Further, in each of the above embodiments, the power feeding devices 1 to 1 ″ are arranged vertically (vertically) on the slide door (slide structure). For example, as shown in FIG. 1 as a plan view, the thickness of the slide door If there is a margin, it is also possible to place the power feeding devices 1 to 1 ″ horizontally on the slide door.

  Moreover, it is also possible to arrange the power feeding devices 1 to 1 ″ horizontally (horizontal) on the vehicle body (fixed structure) instead of the slide door, and arrange the harness fixture 22 on the slide door side instead of the vehicle body side. It is.

  In each of the above embodiments, the corrugated tube 12 is used as the harness protective tube. However, other than the corrugated tube, a resin tube having no irregularities (bellows) or a flexible net-like tube (not shown), or a protective tube is used. It is also possible to bind a plurality of electric wires 11 by tape winding or the like without using. In these cases, these wire harnesses are held and fixed to the harness holding portions 7 and 7 'by bands or the like, or the wire harness is clamped and fixed by the holder base 7a and the holder cover 7b.

  In the above-described embodiment, an example in which the present invention is applied to a slide door of an automobile has been described. However, the present invention is not limited to a slide door of a train, a slide door of a manufacturing apparatus, a detection apparatus, or the like. It is also possible to apply the power feeding devices 1 to 1 ″. The vehicle body and the like are collectively referred to as a fixed structure.
