JP-A-10-181474 (FIGS. 1 and 7) JP 2001-171443 A (FIG. 4) Japanese Patent Laying-Open No. 2005-59745 (FIG. 7) JP 2000-108674 A (FIGS. 1 to 5) Japanese Patent Application Laid-Open No. 10-175483 (FIGS. 5 and 9)

  However, in the prior art shown in FIG. 9, since the wire harness 65 is bent in a substantially V shape in the case 64, there is a concern that the bending durability of the wire harness 65 may be lowered, and the case 64 has a structure. There was a problem of enlargement.

  In the prior art of FIG. 10 described above, although the sliding amount of the sliding door 72 can be accommodated, the wire harness 76 is bent in a substantially J-shape or U-shape. There were concerns that it would decrease, and there was a problem that the structure would be enlarged by the case 73.

  Further, in the prior art shown in FIG. 11, although the sheet 82 can accommodate a long slide amount, the wire harness 83 is bent in a substantially U shape within the case 84. There was a problem that the structure would be enlarged due to the concern that it would decrease or the case 84.

  In the prior art shown in FIG. 12, when a wire harness (not shown) is routed along the link 52 so as to constantly supply power to the roof 56, the wire harness is rotated along with the rotation of the link 52. There is a concern that the extra length is generated and the extra length portion is caught between the links 52 to 54 and damaged.

  In view of the above points, the present invention, for example, arranges a wire harness in a structure such as a rotary door, a structure such as a slide door or a seat, a link structure, and the like. In the structure that absorbs the extra length of the wire harness along with the movement of the wire harness, the structure can be made compact, and in addition, the extra length of the wire harness that can increase the durability accompanying repeated bending of the wire harness The purpose is to provide a structure.

  In order to achieve the above object, a surplus length absorbing structure for a wire harness according to claim 1 of the present invention is provided with harness fixing portions at both ends of a rod-shaped elastic body, and the wire harness extends along the elastic body. In addition, the wire harness is fixed to the harness fixing portions on both ends, and the elastic body is expanded and contracted in the axial direction so that the wire harness can be expanded and contracted.

  With the above configuration, the wire harness portion or both harness fixing portions led out from both harness fixing portions are directly fixed to the movable structure and the fixed structure, and the elastic body becomes the wire as the movable structure rotates and slides. Along with the harness, it extends and contracts in the axial direction (longitudinal direction) to absorb the extra harness length. Examples of the movable structure include a door, a slide door, a slide seat, a link, and the like. Rubber is preferred as the elastic body.

  The surplus length absorption structure of the wire harness according to claim 2 is the surplus length absorption structure of the wire harness according to claim 1, wherein the surplus length is obtained by spirally winding the wire harness around the elastic body. It is characterized by comprising.

  With the above configuration, the spiral winding portion of the wire harness expands and contracts in the axial direction of the elastic body as the elastic body expands and contracts. The number of winding portions may be one, two or more, and the number of windings is set as appropriate according to the length of the elastic body.

  The surplus length absorbing structure for a wire harness according to claim 3 is the surplus length absorbing structure for a wire harness according to claim 1 or 2, wherein an intermediate harness fixing portion is disposed at a middle portion in the longitudinal direction of the elastic body, An intermediate portion of the wire harness is fixed to the harness fixing portion.

  With the above configuration, the elastic body is disposed on both sides of the intermediate harness fixing portion, and each elastic body expands and contracts between the intermediate harness fixing portion and the harness fixing portion on the end side. Accordingly, the expansion / contraction stroke is increased as compared with the case where a single long elastic body is used, and the decrease (sagging) of the elastic force with time is reduced. It goes without saying that the expansion / contraction stroke increases by setting the total length of both elastic bodies longer than that of the elastic bodies according to claims 1 and 2. The winding direction of the wire harness in both elastic bodies may be the same or reverse. The number of intermediate harness fixing parts is not limited to one, but may be two or more.

  According to the first aspect of the present invention, the rod-shaped elastic body expands and contracts in the axial direction together with the wire harness to absorb the extra harness length, so that a conventional case or the like is unnecessary, and the rod-shaped elastic body and the wire harness around the rod-shaped elastic body The space can be saved and the structure can be made compact.

  According to the invention described in claim 2, since the wire harness smoothly expands and contracts in a spirally wound state along the elastic body as the elastic body expands and contracts, excessive stress acts on the winding portion of the wire harness. Without using the wire harness, the durability of the wire harness is improved and the reliability of power supply and the like is improved as compared with the case where the wire harness is bent into a U-shape or the like as in the prior art.

  According to the invention described in claim 3, by setting the elastic body long with the intermediate harness fixing portion as a fulcrum, it is possible to increase the expansion / contraction stroke of the wire harness, and for a long slide stroke such as a slide door or a slide seat. Can respond.

  1 to 3 show an embodiment of a surplus length absorbing structure for a wire harness according to the present invention.

  As shown in FIGS. 1A and 1B, this structure uses a cylindrical (bar-shaped) elastic body 1 in a free state, and a rigid harness fixing portion 2 is provided at one end and the other end of the elastic body 1. The wire harness 3 is spirally wound around the elastic body 1, one end of the wire harness 3 is fixed to the harness fixing portion 2 on one end side, and the other end of the wire harness 3 is fixed to the harness fixing portion 2 on the other end side. It is constituted as follows.

  The elastic body 1, the two harness fixing portions 2, and the member 4 for fixing the wire harness 3 to the fixing portion 2 constitute one harness extra length absorber 5, and the harness extra length absorber 5 and the wire harness 3 Thus, the wire harness assembly 6 is configured.

  The elastic body 1 is preferably made of natural rubber or synthetic rubber, and the maximum elongation rate of the elastic body 1 is about 100% (twice the initial length when the elastic body 1 is pulled) or more. The above is preferable. The initial length, outer diameter, and material of the elastic body 1 are appropriately set according to the stroke, the moving operation force, and the like of a structure (not shown) such as a rotary type, a slide type, and a link type to be applied.

  The harness fixing portions 2 provided at both ends of the elastic body 1 are preferably made of synthetic resin, and are formed in a substantially cylindrical shape with a bottom larger in diameter than the elastic body 1 (the bottom portion is denoted by reference numeral 7). Is fixed by bonding, welding or the like in a state of being fitted into the hole 25 inside the substantially cylindrical peripheral wall 8. The elastic body 1 and the harness fixing portion 2 can be easily formed and fixed by integral molding (two-color molding or the like). It is also possible to integrally form the harness fixing portion 2 with the same elastic member as the elastic body 1.

  As shown in FIG. 3 (a state in which the elastic body 1 is extended), a substantially V-shaped or arc-shaped groove 9 for positioning and routing the wire harness 3 is provided in the longitudinal direction on the outer surface of each harness fixing portion 2. ing. Both groove portions 9 are located on the same straight line. At the base end of the harness fixing part 2 excluding the groove part 9, a hooking hook part 10 is formed. As shown in FIG. 1, the wire harness 3 is routed linearly along the groove portion 9, and the straight portion 11 is fixed to the harness fixing portion 2 with a fixing member such as an adhesive tape 4 or a band (not shown).

  In the example of FIG. 1, the wire harness 3 is wound around the elastic body 1 relatively densely, such as about three turns, and each winding portion 12 is positioned at substantially the same pitch in the longitudinal direction of the elastic body 1, with one end and the other A straight portion 11 continues in the longitudinal direction of the wire harness so as to intersect each winding portion 12 at an angle of approximately 90 °. The number of windings of the winding part 12 of the wire harness 3 is appropriately set according to the amount of expansion / contraction.

  The straight portion 11 of the wire harness 3 is pulled in the longitudinal direction from the compressed state of the wire harness 3 in FIG. 1, or both the harness fixing portions 2 are pulled in the harness longitudinal direction (in this case, an illustration such as a bracket or a hook on the harness fixing portion 2) As shown in FIGS. 2A and 2B, the elastic body 1 gradually decreases in diameter in a taper shape in the longitudinal direction from the harness fixing portions 2 on both sides to the center. While being stretched in the tensile direction. At the same time, the spiral winding portion 12 of the wire harness 3 extends along the elastic body 1, and the pitch of the winding portion 12 increases.

  When the tensile force of the elastic body 1 is released from the extended state of the wire harness 3 in FIG. 2, the wire harness 3 elastically returns to the initial state in FIG. 1 together with the elastic body 1. In FIG. 2, the wire harness 3 is fixed to the harness fixing portion 2, and the starting end portion 13 and the terminal end portion 13 of the winding portion 12 are in contact with the base end surface 14 of the harness fixing portion 2 in a state of being substantially orthogonal to each straight portion 11. Since the start end portion 13 and the end end portion 13 act as stoppers, the length of the winding portion 12 does not fluctuate even when the wire harness 3 is pulled strongly. Further, when the elastic body 1 returns, the wire harness 3 is returned while being spread out, so that slack due to the extra length of the wire harness 3 does not occur. The wire harness 3 may be a cabtyre cable or a single electric wire.

  The extra length absorption structure of the wire harness includes, for example, a rotating door of an automobile (see the conventional example in FIG. 9), a sliding door of the automobile (see the conventional example of FIG. 10), and a slide sheet of the automobile (see FIG. It can be applied to a link mechanism of an automobile (see the conventional example in FIG. 12) and the like.

  When applied to a rotary door, for example, in the example of FIG. 9, the harness surplus absorber 5 (FIG. 1) composed of the elastic body 1 and the harness fixing portion 2 is substantially horizontal on the inner panel 62 of the door 61. The wire harness portion led out from one end side of the harness surplus length absorber 5 is fixed to the door 61 side and wired, and the wire harness portion led out from the other end side is fixed to the vehicle body 63 side. And route it.

  Alternatively, a hook (not shown) of one harness fixing portion 2 (FIG. 1) is hooked and fixed to the inner panel 62 of the door 6, and a hook (not shown) of the other harness fixing portion 2 is fixed to the vehicle body 63. Hook and fix. In this case, it is not necessary to fix the wire harness portion 3 to the door 61 or the vehicle body 63. It is also possible to arrange the harness surplus length absorber 5 on the vehicle body 63 side. Thus, for example, when the door 61 is opened, the elastic body 1 is extended together with the winding portion 12 of the wire harness 3, and when the door 61 is closed, the elastic body 1 is compressed together with the winding portion 12 of the wire harness 3.

  When applied to a sliding door, for example, in the example of FIG. 10, the harness surplus length absorber 5 (FIG. 1) is disposed substantially horizontally on the vehicle body 71 side and is led out from one end side of the harness surplus length absorber 5. The wired wire harness portion is fixed and routed on the vehicle body 71 side, and the wired harness portion led out from the other end side is fixed and routed on the slide door 72 side.

  Alternatively, the hook (not shown) of each harness fixing portion 2 (FIG. 1) is hooked and fixed on the vehicle body 71 or the slide door 72, and the wire harness portion 3 is not fixed to the vehicle body 71 or the slide door 72. To do. It is also possible to dispose the harness surplus length absorber 5 on the slide door 72 side. Thus, for example, the elastic body 1 is compressed together with the winding portion 12 of the wire harness 3 when the slide door 72 is opened, and the elastic body 1 is extended together with the winding portion 12 when the slide door 72 is closed.

  When applied to a slide seat, for example, in the example of FIG. 11, the harness surplus length absorber 5 (FIG. 1) is arranged almost horizontally on the floor 81 of the vehicle body and is led out from one end side of the harness surplus length absorber 5. The wired wire harness portion fixed to the floor 81 is routed, and the wire harness portion led out from the other end side is fixed to the seat 82 and wired.

  Or the hook (not shown) of each harness fixing | fixed part 2 (FIG. 1) is hooked and fixed to the floor 81 or the sheet | seat 82, and fixation of the wire harness part 3 to the floor 81 or the sheet | seat 82 becomes unnecessary. It is also possible to arrange the harness surplus length absorber 5 on the seat 82 side. Accordingly, for example, the elastic body 1 is compressed in a free state together with the winding portion 12 of the wire harness 3 at the forward end position (shown by a solid line) of the slide sheet 82, and the elastic body is moved at the backward end position (shown by a chain line) of the slide sheet 82. 1 is stretched together with the winding part 12.

  When applied to the link mechanism, for example, as shown in the example of the link mechanism of FIGS. 4 to 5, the wire harness 3 is routed and fixed to the movable link 15, and the harness is connected to the fixed link 16 connected to one end side of the movable link 15. The surplus length absorber 5 is disposed, one side of the wire harness 3 is routed from the movable link 52 to the fixed member 17 via the harness surplus length absorber 5, and the other end of the wire harness 3 is connected to the other end side of the movable link 15. It is routed to the link bracket 18 connected to the.

  A movable structure (not shown) such as an automobile roof is fixed to the fixed link 16, and the link bracket 18 is fixed to the vehicle body side. Sub-links 19 are arranged substantially parallel along the movable link 15, and the links 15 and 19 are rotatably supported by the shaft portions 20. The wire harness 3 is preferably fixed to the movable link 15 with an existing fixing member 21 such as a clamp or a band clip.

  In the closed (mounted) state of the roof of FIG. 4, the elastic body 1 is compressed into a free state together with the winding portion 12 of the wire harness 3. Elongate to form the extra length portion (substantially U-shaped bent portion) 22 of the wire harness 3 on the link turning front end side. This surplus length portion 22 is a portion that is bent while the substantially straight portion 23 on the upper end side of the link is extended in FIG.

  FIGS. 6-8 shows other embodiment of the surplus length absorption structure of the wire harness which concerns on this invention.

  This structure is characterized in that an intermediate harness fixing portion 24 is provided between two in-line (coaxial) elastic bodies 1 ′, and the other configuration is substantially the same as that of the embodiment of FIGS. It is the same. The same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 6 (a) and 6 (b), the intermediate harness fixing portion 24 is preferably made of a synthetic resin, and a circular hole portion 25 for inserting and fixing each end portion of the two elastic bodies 1 'is coaxially formed at both ends. And a partition wall (not shown) is provided between the two holes 25. The end of each elastic body 1 ′ is fixed in the hole 25.

  Each elastic body 1 'is formed in a cylindrical shape with natural rubber or synthetic rubber. As shown in FIG. 8 (extension state of the elastic body 1 ′), the intermediate harness fixing portion 24 is substantially the same as the harness fixing portions 2 on both sides (except that there is no tape fixing collar portion 10 and no bottom portion 7). It has an external shape, and has a substantially V-shaped or arcuate groove 9 'for harness positioning and fixing in the axial direction. The groove portions 9 and 9 'of the harness fixing portions 2 and 24 are formed on the same straight line.

  The hole 25 of the intermediate harness fixing part 24 may be penetrated in the axial direction, and the long elastic body (1 ') may be fixed in a state of being inserted through the hole (25). In this case, the appearance is not different from the case where two elastic bodies 1 'are used.

  As shown in FIG. 6, the wire harness 3 ′ is wound around each elastic body 1 ′, and in one elastic body 1 ′, one of the winding portions 12 ′ of the wire harness 3 ′ is a harness fixing portion on the end side. 2 is linearly derived along the groove portion 9 (the straight portion is indicated by reference numeral 11 '), and the other of the winding portions 12' is linearly routed along the groove portion 9 'of the intermediate harness fixing portion 24 ( The straight part is indicated integrally with 26) on one side of the other elastic body side winding 12 '. The other of the winding portions 12 'on the other elastic body side is led out linearly along the groove 9 of the harness fixing portion 2 on the end portion side (the straight portion is indicated by reference numeral 11').

  In one elastic body 1 ′ and the other elastic body 1 ′ in this example, the winding direction of the winding portion 12 ′ of the wire harness 3 ′ is the same. In each elastic body 1 ′, the winding direction of the winding portion 12 ′ can be reversed. In any case, the start end portions 13 and 27 and the end portions 13 and 27 of each winding portion 12 ′ are substantially orthogonal to the straight portions 11 ′ and 26, and the base end face 14 of the harness fixing portion 2 on the end side and the intermediate harness It abuts against the end face 28 of the fixing portion 24 and acts as a stopper when the harness is pulled. The straight portions 11 ′ and 26 ′ are fixed to the harness fixing portions 2 with fixing members such as an adhesive tape 4 and a band.

  As shown in FIGS. 7 and 8, each elastic body 1 ′ is gradually reduced in a taper shape so that the central portion has a minimum diameter with the harness fixing portion 2 and the intermediate harness fixing portion 24 at the end side as fulcrums during pulling. While extending in the axial direction.

  In the pulling operation, the elastic body 1 ′ may be extended integrally with the winding portion 12 ′ by pulling the portions 11 ′ derived from the harness fixing portions 2 on both ends of the wire harness 3 ′, or the harnesses on both ends may be extended. A tension operation part (not shown) such as a hook or a bracket may be provided integrally with the fixed part 2, and each elastic body 1 ′ may be extended integrally with the winding part 12 ′ by pulling the tension operation part.

  According to the embodiment of FIGS. 6 to 8, by using two elastic bodies 1 ′ or one long elastic body (1 ′) supported by the harness fixing portion 24 in the middle, the wire harness 3 ′ The amount of expansion / contraction can be set large. For example, even if a single elastic body 1 is simply elongated in the embodiment of FIG. 1, the central portion in the longitudinal direction of the elastic body 1 is reduced to the minimum during tension and no further elongation occurs. Difficult to get.

  In this respect, the elastic body 1 'is connected in series with two or more via the intermediate harness fixing portion 24, so that the amount of expansion and contraction increases, and a structure such as a slide door or slide seat with a large slide amount. It becomes possible to cope with.

  The embodiment of FIGS. 6 to 8 can be applied to the rotating door of FIG. 9, the slide door of FIG. 10, the slide seat of FIG. 11, the link mechanism of FIGS. These descriptions are substituted by the description of the embodiment of FIG.

  Further, for example, the intermediate harness fixing portion 24 is fixed to a rotating or sliding structure or a structure on the fixed side such as a vehicle body with respect to these structures by a hook portion or a locking clip (not shown). If the elastic bodies 1 ′ on both sides are bent in different directions around the fulcrum 24, the wire harness 3 ′ can be bent and routed.

  In the embodiment of FIG. 6, the length of each elastic body 1 ′ is set to be the same. However, for example, the length of each elastic body 1 ′ is different, and the wire harness 3 ′ wound around each elastic body 1 ′ is used. It is also possible to make the number of windings differ depending on the length of each elastic body 1 ′.

  In each of the above embodiments, the wire harnesses 3 and 3 ′ are spirally wound around the elastic bodies 1 and 1 ′. However, for example, the winding portion 12 is stopped and the wire harnesses 3 and 3 ′ are elastic. It is also possible to route in a curved line along the elastic bodies 1 and 1 ′ with an extra length corresponding to the expansion and contraction length of 1 and 1 ′. However, in this case, there is a concern that the wire harnesses 3 and 3 ′ may be loosened when the elastic bodies 1 and 1 ′ are compressed, and may be caught.
