[0019] [Description of Embodiments of the Present Disclosure]

[0020] First, embodiments of the present disclosure will be described below.

[0021] (1) A wire harness routing device disclosed herein comprises: a guide rail having an insertion hole formed therein for inserting a wire harness; and a slider that slides relative to the guide rail together with the wire harness, the wire harness routing device comprising a wire harness restriction portion that is arranged along the wire harness in the insertion hole, restricts movement of the wire harness in a direction different from the direction of sliding movement, and moves in the insertion hole in association with the sliding movement of the slider.

[0022] According to the above structure, the wiring path of the harness in the guide rail can be restricted by the harness restricting portion. In addition, the harness restricting portion moves in the insertion hole along with the movement of the slider, so it is possible to prevent the harness restricting portion from becoming an obstacle to the movement of the slider.

[0023] (2) The harness restricting portion is elastically deformable in accordance with the movement of the slider, and an end portion of the harness restricting portion is fixed to the slider side.

[0024] In this case, the wiring path of the wire harness can be restricted with a simplified structure, and the wire harness restricting portion can be restricted from becoming an obstacle to the movement of the slider by elastic deformation.

[0025] (3) A winding portion for winding up the harness restricting portion is provided on the outer side of the guide rail.

[0026] In this case, the harness restricting portion can be stored outside the guide rail with a simplified structure.

[0027] (4) An excess length storage portion is provided, the excess length storage portion storing the excess length of the wire harness led out to the outside of the guide rail, the wire harness being wound into a spiral shape of two or more turns in the excess length storage portion.

[0028] In this case, since the wire harness is stored in a spiral shape in the excess length storage portion, the length of the excess length storage portion can be shortened compared to a structure in which the wire harness is stored in a U-shape in a long storage box.

[0029] (5) The wire harness includes a plurality of electric wires and an outer casing that accommodates the plurality of electric wires, the outer casing is inserted into the guide rail in a direction in which a vertical direction is longer than a width direction, and the wire harness restricting portion suppresses a distortion of the wire harness.

[0030] When the wire harness is inserted into the guide rail in a direction in which the vertical direction is longer than the width direction, the outer diameter of the curved portion of the wire harness can be reduced and miniaturization can be achieved compared to a structure in which the vertical direction is shorter than the width direction. On the other hand, there is a problem that the wire harness becomes a longitudinally long shape and is easily skewed. According to this structure, even if the structure is easy to be skewed due to the direction of the wire harness for miniaturization, the skewness of the wire harness can be suppressed by the wire harness restriction portion.

[0031] [Details of the embodiments of the present disclosure]

[0032] The following is a reference to the attached Figure 1 Specific examples of the substrate, component mounting substrate, and electrical junction box of the present disclosure will be described. The present disclosure is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0033] <Implementation Method>

[0034] One side reference Figure 1 to Figure 7 The following describes an embodiment of the invention.

[0035] The wire harness routing device 10 of this embodiment is fixed to a floor under a seat 60 in a vehicle such as an automobile (not shown), and routes a wire harness 11 connected to an electrical component of the seat 60. Figure 1 The description will be given with the X direction as the front, the Y direction as the left, and the Z direction as the top.

[0036] like Figure 1As shown in FIG. 1 , the seat 60 can slide in the front-rear direction relative to the guide rail 20, and the guide rail 20 is fixed to the floor of the passenger compartment of the vehicle body (not shown) by bolts or the like. The seat 60 is equipped with various electrical components such as an electric automatic adjustment device, a seat heater, a sensor for detecting whether a passenger is seated, and a sensor for detecting whether the seat belt is fastened. The lower part of the seat 60 is fixed to the slide member 26 (at the bottom of the guide rail 20) in the guide rail 20. Figure 1 Only the sliding member 26 of one guide rail 20 is shown in the figure, and the sliding member of the other guide rail 20 is omitted).

[0037] (Harness 11)

[0038] The wire harness 11 is laid on the floor of the vehicle body (under a mat, panel, etc.) or under the floor, and is connected to an ECU (Electronic Control Unit) or other equipment on the vehicle body side. The wire harness 11 is used to supply power and send and receive signals between the equipment on the vehicle body side and the electrical components of the seat 60.

[0039] The wire harness 11 routed between the seat 60 and the vehicle body is inserted (routed) through the guide rail 20 under the seat 60. Figure 3 As shown, the wire harness 11 includes a plurality of (nine in this embodiment) electric wires 12 and an outer casing 14 that collectively houses the plurality of electric wires 12. Each electric wire 12 is a covered electric wire having a metal conductor covered with an insulating layer, and is connected to various electric components of the seat 60.

[0040] The outer casing 14 is made of, for example, an insulating synthetic resin and extends in a strip-like shape in the front-rear direction in a state of surrounding the plurality of wires 12 arranged vertically. The outer casing 14 includes a strip-like outer casing body 15 extending along the plurality of wires 12 and a strip-like outer casing cover 16. A plurality of slit-like cutouts 15A (see FIG. 1 ) are formed in the outer casing body 15. Figure 6 ), so that the outer body 14 is bent only to one side (the excess length storage portion 40 side) in the left-right direction. In addition, the wire harness 11 laid outside the guide rail 20 and the excess length storage portion 40 is laid in a state of multiple wires 12 not covered by the outer body 14.

[0041] (Wire harness routing device 10)

[0042] like Figure 2 , Figure 4 As shown, the wire harness routing device 10 includes a guide rail 20 , a slider 26 slidably disposed in the guide rail 20 , a harness restricting portion 30 restricting a routing path of the wire harness 11 , and an excess length storage portion 40 storing an excess length portion 11A of the wire harness 11 .

[0043] (Guide rail 20)

[0044] The guide rail 20 is made of metal, such as Figure 1As shown, a pair of seats 60 are provided for each seat 60, extending linearly in the front-rear direction. Figure 3 As shown, each guide rail 20 is formed with an insertion hole 21 in the front-to-back direction through which the slide member 26 is inserted. The insertion hole 21 is a rectangular shape that is long in the left-right direction, and a bottom groove 22 whose width dimension decreases at the lower side extends in the front-to-back direction. Above the insertion hole 21, a through groove 24 that communicates with the outside extends in the front-to-back direction in a groove shape.

[0045] (Slider 26)

[0046] The slider 26 is made of, for example, synthetic resin or metal, and can slide in the front-rear direction relative to the guide rail 20. It has a slider body 27 disposed in the insertion hole 21, and an assembly portion 28 protruding upward in a plate shape from the upper surface of the slider body 27. The width dimension of the slider body 27 is larger than the interval of the through groove 24. The assembly portion 28 slides between the cutouts formed in a mat or the like on the floor, and is fastened to the assembly portion (not shown) of the seat 60 by a fastening member (not shown) such as a bolt. In addition, as shown in FIG. Figure 5 As shown in FIG. 1 , a cylindrical guide member 17 through which a plurality of electric wires 12 are inserted is provided in front of the slider 26, and a pair of extended fitting portions 17C extending from the rear of the guide member 17 are fixed to the fitting portion 28. A through hole 17D is formed through each of the extended fitting portions 17C, and a shaft portion of a bolt as a fastening member is inserted through a fastening hole (not shown) formed through the fitting portion 28 and the through hole 17D and fastened with a nut. The guide member 17 is made of synthetic resin, and includes an outer body fixing portion 17A connected to the rear end of the outer body 14 and positioning the outer body 14, a lead-out port 17B for leading the plurality of electric wires 12 upward, an insertion groove 18A into which a metal fixing plate 31 at the rear end of the harness restricting portion 30 is inserted, and a pair of fixing member storage chambers 18B for storing the fixing member 19. Behind the outer body fixing portion 17A inside the guide member 17, the plurality of electric wires 12 extend rearward from the rear end of the outer body 14.

[0047] The fixing member 19 is cylindrical, and is made of metal such as aluminum, aluminum alloy, copper, copper alloy, iron, or synthetic resin, and is formed into the same outer peripheral shape as the fixing hole 31A, and is pressed into the fixing hole 31A of the metal fixing plate 31 to fix the position of the metal fixing plate 31 (the rear end of the harness restriction portion 30). In addition, the fixing member 19 is not limited to this, and for example, it can also be a fixing member composed of a bolt having a head larger than the fixing hole 31A and a nut having an outer diameter larger than the fixing hole 31A, and the shaft of the bolt is inserted into the fixing hole 31A of the metal fixing plate 31. The shaft is tightened with the nut. The insertion groove 18A has a gap of a predetermined size. The fixing member storage chamber 18B is provided in the middle of the insertion groove 18A in the front-to-back direction, forming a space in which the fixing member 19 can be inserted, and the front-to-back movement of the fixing member 19 stored in the fixing member storage chamber 18B is restricted.

[0048] (Harness Restriction Section 30)

[0049] The harness restraining portion 30 is a thin-walled elastically deformable leaf spring made of a strip of metal such as copper, copper alloy, aluminum, or aluminum alloy, and extends in the front-to-back direction along the harness 11 inserted into the through hole 21. The leaf spring is naturally curved with a certain curvature, and the restoring force (load) generated when stretched into a straight line becomes constant. Figure 5 As shown, at the rear end (one end side) of the harness restricting portion 30, a metal fixing plate 31 made of a metal thicker than the leaf spring overlaps the leaf spring, and the metal fixing plate 31 is fixed to the leaf spring by welding or other fixing means. A circular fixing hole 31A is formed through the metal fixing plate 31, and the fixing member 19 pressed into the fixing hole 31A is locked with the guide member 17, so that the harness restricting portion 30 moves in the insertion hole 21 along with the sliding movement of the slider 26.

[0050] like Figure 6 As shown, the front end side (other end side) of the harness restricting portion 30 is wound around the winding portion 32 disposed outside the guide rail 20. The harness restricting portion 30 extends along the harness 11 near the harness 11, thereby restricting the movement (displacement) of the harness 11 in the guide rail 20 in the vertical direction and the horizontal direction.

[0051] The winding portion 32 includes a cylindrical barrel portion 33 around which the harness restriction portion 30 is wound, and a pair of protruding portions 34 protruding in a flange shape from the edge of the barrel portion 33. The harness restriction portion 30 is elastically deformed and wound around the outer periphery of the barrel portion 33 between the pair of protruding portions 34. A support shaft portion 36 is inserted through the inner side of the barrel portion 33, and the support shaft portion 36 is fixed to, for example, the floor of the vehicle or the excess length storage portion 40. The support shaft portion 36 is cylindrical and has an outer diameter smaller than the inner diameter of the barrel portion 33. A head portion 36A having an outer diameter larger than the inner diameter of the barrel portion 33 is formed at the top end of the support shaft portion 36, and the winding portion 32 is restricted from being detached by the head portion 36A. The take-up portion 32 is rotatable relative to the support shaft portion 36. When the wire harness 11 and the wire harness restriction portion 30 slide and move in the same direction as the seat 60 as the seat 60 slides, the take-up portion 32 rotates toward the moving direction of the wire harness 11 and the wire harness restriction portion 30, and the wire harness restriction portion 30 is taken up by the take-up portion 32 by the moving distance of the wire harness restriction portion 30. In the present embodiment, since the wire harness restriction portion 30 is in a wound state in a natural state, it is maintained in a state of being wound around the outer peripheral surface of the barrel portion 33 even without using a fixing method. In addition, the relationship between the wire harness restriction portion 30 and the take-up portion 32 is not limited to this. For example, the end of the wire harness restriction portion 30 may be fixed to the barrel portion 33 by a fixing method such as welding or bonding.

[0052] The excess length storage portion 40 stores the excess length portion 11A of the wire harness 11 that is not stored in the guide rail 20. Figure 7 As shown in FIG. 5 , the housing body 41 and the cover 55 are provided. The housing body 41 includes a flat bottom 42, a housing wall 46 for housing the wire harness 11 in a spiral shape, and a guide wall 48 for guiding the wire harness 11 into the housing wall 46. A lead-out portion 43 is formed in the middle of the bottom 42, and the lead-out portion 43 is used to lead the wire harness 11 onto the floor of the vehicle, under the floor, etc. The lead-out portion 43 is formed from a through hole 42A (see FIG. 5 ) formed in the bottom 42. Figure 2 ) with a raised edge, such as Figure 7 As shown, an insertion groove 44 is formed to insert the wire harness 11. A storage wall 46 rises from the bottom surface 42 in a circular ring shape, and a storage space for the wire harness 11 is formed between the lead-out portion 43 and the storage wall 46. The guide wall 48 guides the traveling direction of the wire harness 11 in front of the guide rail 20 in a direction bent toward the storage space side in the storage wall 46 relative to the front-rear direction. A plurality of (three in this embodiment) stopper portions 50 are formed at positions adjacent to the outer side of the storage wall 46, which can stop the cover portion 55 with screws. A threaded hole is formed in each stopper portion 50.

[0053] A recessed wall 52 is provided on the side of the storage wall 46 in the guide wall 48, and the winding portion 32 can be rotatably stored in the recessed wall 52. The recessed wall 52 ensures a space for storing the winding portion 32 by cutting the wall of the guide wall 48 into an arc shape. A guide rail fixing portion 54 is arranged at the rear of the guide wall 48 and below the bottom portion 42. The guide rail fixing portion 54 is an inverted U-shape, and a fastening hole 54A is formed through the upper surface portion, and the end of the guide rail 20 can be fastened to the fastening hole 54A by a bolt. When the guide rail 20 is fixed to the guide rail fixing portion 54, the inner wall (hole wall) of the insertion hole 21 of the guide rail 20 is connected to the inner surface of the guide wall 48 and the upper surface of the bottom portion 42.

[0054] The cover 55 is formed in a flat plate shape corresponding to the shape of the storage section body 41. A protrusion 56 protruding upward in a circular shape is formed at a position corresponding to the winding section 32 in the cover 55, and a circular recess (not shown) is formed on the lower surface side of the protrusion 56 to fit the upper end of the winding section 32. A plurality of threaded holes 57 are formed through the cover 55, and the shafts of the screws used to screw the stopper 50 to the storage section body 41 can be inserted through the plurality of threaded holes 57. A peripheral wall 58 covering the outer side of the upper end of the storage section body 41 is formed at the peripheral edge of the cover 55.

[0055] Next, the operation of the seat 60 when sliding will be described.

[0056] When the seat 60 is located on the rear side of the guide rail 20 ( Figure 2 The belt-shaped harness restriction portion 30 is in a state of extending linearly in the guide rail 20. Figure 3 As shown, the harness restraint 30 in this state is arranged between the inner wall of the guide rail 20 and the harness restraint 30, so the displacement of the wiring path of the harness 11 and the skewness of the harness 11 can be restricted by the harness restraint 30. In addition, the harness restraint 30 in this state is deformed from the natural state, so that a rebound force (toward the side of the hole wall 21A of the insertion hole 21) is generated. When the harness 11 is bent or the wiring path is bent, the harness restraint 30 abuts against the harness 11, and the harness 11 can be held between the hole wall 21A of the insertion hole 21 and the harness restraint 30.

[0057] Next, when the user slides the seat 60 forward, the slider 26 and the harness 11 slide forward, and the harness restricting portion 30 in the guide rail 20 slides forward ( Figure 4 At this time, the harness restriction portion 30 led out in front of the guide rail 20 is wound up by the rotating winding portion 32, and is wound up while elastically restoring (refer to Figure 6 ).

[0058] Next, when the user slides the seat 60 to the rear side from this state, the slider 26 and the harness 11 slide to the rear, and the harness restricting portion 30 in the guide rail 20 slides to the rear ( Figure 2 At this time, the harness restriction portion 30 on the front side of the guide rail 20 is rewound by the winding portion 32 rotating to the opposite side while being elastically deformed, and becomes a state of extending linearly.

[0059] According to this embodiment, the following actions and effects are achieved.

[0060] According to the present embodiment, a wire harness routing device 10 is provided, comprising: a guide rail 20 having an insertion hole 21 through which a wire harness 11 is inserted; and a slider 26 that slides relative to the guide rail 20 together with the wire harness 11. The wire harness routing device 10 comprises a wire harness restricting portion 30 that is arranged along the wire harness 11 in the insertion hole 21, restricts movement of the wire harness 11 in a direction different from the front-rear direction (direction of sliding movement), and moves in the insertion hole 21 in association with the sliding movement of the slider 26.

[0061] According to the present embodiment, the harness restricting portion 30 restricts the routing path of the harness 11 in the guide rail 20. In addition, the harness restricting portion 30 moves in the insertion hole 21 as the slider 26 moves, so that the harness restricting portion 30 can be prevented from becoming an obstacle to the movement of the slider 26.

[0062] In addition, the harness restricting portion 30 is elastically deformable in accordance with the movement of the slider 26 , and an end portion of the harness restricting portion 30 is fixed to the slider 26 side.

[0063] In this case, the routing path of the wire harness 11 can be restricted with a simplified structure, and the wire harness restriction portion 30 can be prevented from becoming an obstacle to the movement of the slider 26 by elastic deformation.

[0064] Furthermore, a winding portion 32 for winding the wire harness restricting portion 30 is provided on the outer side of the guide rail 20 .

[0065] In this way, the harness restricting portion 30 can be stored outside the guide rail 20 with a simplified structure.

[0066] Furthermore, an excess length storage portion 40 is provided. The excess length storage portion 40 stores the excess length portion 11A of the wire harness 11 led out to the outside of the guide rail 20 . The wire harness 11 is wound into a spiral shape with two or more turns in the excess length storage portion 40 .

[0067] In this way, since the wire harness 11 is spirally stored in the excess length storage portion 40, the length of the excess length storage portion 40 can be shortened compared to a structure in which the wire harness 11 is folded back in a U shape and stored in a long storage box.

[0068] The wire harness 11 includes the plurality of electric wires 12 and the outer casing 14 that accommodates the plurality of electric wires 12 . The outer casing 14 is inserted into the guide rail 20 in a direction in which the vertical direction is longer than the width direction. The wire harness restricting portion 30 suppresses the wire harness 11 from being distorted.

[0069] When the wire harness 11 is inserted into the guide rail 20 in a direction in which the vertical direction is longer than the width direction, the outer diameter of the curved portion of the wire harness 11 can be reduced and miniaturization can be achieved compared to a structure in which the vertical direction is shorter than the width direction. On the other hand, there is a problem that the wire harness 11 becomes a longitudinally long shape and is easily skewed. According to the present embodiment, even in a structure in which the wire harness 11 is easily skewed due to the orientation of the wire harness for miniaturization, the skewness of the wire harness 11 can be suppressed by the wire harness restriction portion 30.

[0070] <Other Implementation Methods>

[0071] The technology described in this specification is not limited to the embodiments described in the above description and drawings, and for example, the following embodiments are also included in the technical scope of the technology described in this specification.

[0072] (1) The number of turns of the wire harness 11 in the excess length storage portion 40 is not limited to the number of turns in the above-mentioned embodiment, and can be set to a different number of turns. In addition, the number of turns in the excess length storage portion 40 before and after the sliding member 26 is not limited to the structure in which the number of turns is changed according to the position of the seat 60 and the slider 26 (the position in the sliding direction), and can be set to a structure in which the number of turns is not changed according to the position of the seat 60 and the slider 26 (a structure in which only the intervals between adjacent wire harnesses 11 in the spiral wire harness 11 are changed).

[0073] (2) The harness restraining portion 30 is an elastic body, but the present invention is not limited thereto. For example, the harness restraining portion may be formed of a resin or a fiber.

[0074] (3) The take-up portion 32 may be arranged at a different position. For example, the front end side of the harness restricting portion may be fixed to the guide rail 20, and the rotatable take-up portion 32 may be fixed to the rear end side (slider 26 side) of the harness restricting portion.

[0075] (4) The number of wires 12 constituting the wiring harness 11 is not limited to the number in the above embodiment, and can be changed to various numbers. For example, the wiring harness 11 can be constituted by a single wire 12. In addition, the outer casing 14 for protecting the wires 12 is also not limited to the shape in the above embodiment, and can be changed in various ways. In addition, for example, the wiring harness 11 can be constituted by only the wires 12 without using the outer casing 14.

[0076] (5) The slider 26 is fixed to the seat 60 as the sliding object, but the present invention is not limited to this. For example, a sliding door may be used as the sliding object, and the slider 26 may be fixed to the sliding door.
