[0009] Hereinafter, a wiring structure according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment. In addition, the components in the following embodiment include those that a person skilled in the art can easily imagine or that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 11. This embodiment relates to a wiring structure.

Fig. 10 shows a cross section taken along line XX in Fig. 1.

[0011] The wiring structure 1 shown in FIG. 1 is mounted on a vehicle 100. The illustrated vehicle 100 is an automobile having a power source such as an engine or a motor. As shown in FIGS. 1 to 3, the wiring structure 1 of this embodiment has a first protector 2, a holding member 3, an exterior member 4, a restricting member 5, a second protector 6, a rotating member 7, and an electric wire W. The electric wire W is wired between a vehicle body 110 and a sliding door 120 of the vehicle 100. The electric wire W is connected to a power source such as a battery, a control unit, etc. at the vehicle body 110. The electric wire W is connected to a device of the sliding door 120 at the sliding door 120.

[0012] The sliding door 120 slides along a first direction X relative to the vehicle body 110. The first direction X is, for example, the front-rear direction of the vehicle 100. The sliding door 120 slides while being guided, for example, by a rail arranged in the vehicle body 110. The sliding door 120 may slide by the operation of a link mechanism that connects the vehicle body 110 and the sliding door 120.

[0013] 2, the second protector 6 and the exterior member 4 are drawn by solid lines when the sliding door 120 is in the fully closed position, and the second protector 6 and the exterior member 4 are drawn by dashed lines when the sliding door 120 is in the fully open position.

[0014] The first protector 2 is a protector disposed on the vehicle body 110. The second protector 6 is a protector disposed on the sliding door 120, and moves in the first direction X together with the sliding door 120. The rotating member 7 is rotatably supported by the second protector 6. The exterior member 4 is a member that protects the electric wires W. The exterior member 4 extends from the first protector 2 to the second protector 6. The exterior member 4 is a flexible tubular member that deforms in accordance with the movement of the sliding door 120.

[0015] As shown in FIG. 3, the restricting member 5 is inserted into the exterior member 4. The restricting member 5 is a member that restricts the curved shape of the exterior member 4. The wiring structure 1 of this embodiment is configured so that the restricting member 5 is less likely to be damaged when the exterior member 4 is stepped on by a user. More specifically, as shown in FIG. 3, a first end portion 41 of the exterior member 4 is held by a spherical holding member 3. The first protector 2 supports the holding member 3 so that the holding member 3 is rotatable.

[0016] When the exterior member 4 is stepped on by a user, the holding member 3 rotates so that the load is received by the wide surfaces of the exterior member 4 and the restricting member 5. This prevents stress concentration from occurring in the restricting member 5.

[0017] The exterior member 4 of this embodiment is a member called a corrugated tube. The exterior member 4 has flexibility and can be curved and deformed between the first protector 2 and the second protector 6. The exterior member 4 is molded, for example, from an insulating synthetic resin. As shown in FIG. 3, the exterior member 4 has a first end 41 and a second end 42. The first end 41 is an end on the side of the vehicle body 110. The first end 41 is held by the holding member 3 and supported by the first protector 2. The second end 42 is an end on the side of the sliding door 120. The second end 42 is held by a rotating member 7 arranged on the sliding door 120.

[0018] As shown in Fig. 4, the cross-sectional shape of the exterior member 4 has a longitudinal direction LD and a lateral direction SD. The cross-sectional shape of the exterior member 4 in this embodiment is an ellipse. That is, the cross-sectional shape of the exterior member 4 has arc portions 4a at both ends in the longitudinal direction LD. The cross-sectional shape of the exterior member 4 may have a linear portion 4b between the two arc portions 4a.

[0019] The exterior member 4 is disposed so that the longitudinal direction LD is aligned with the vehicle vertical direction. The rotating member 7 of the second protector 6 holds the second end 42 of the exterior member 4 so as not to allow the longitudinal direction LD to tilt with respect to the vehicle vertical direction. Meanwhile, the first protector 2 supports the spherical holding member 3 so as to allow the longitudinal direction LD to tilt with respect to the vehicle vertical direction.

[0020] When a user steps on the exterior member 4, an external force FV in the longitudinal direction LD shown in FIG. 4 acts on the exterior member 4. Since the cross-sectional shape of the exterior member 4 is vertically elongated, a moment M1 that tends to tip the exterior member 4 sideways is generated in the exterior member 4. The moment M1 causes the exterior member 4 and the restricting member 5 housed therein to undergo twisting deformation so that the stepped portion tips over. As a result, the exterior member 4 and the restricting member 5 can receive the external force FV over a wide surface, as shown in FIG. 11. Therefore, the wiring structure 1 of this embodiment can suppress the occurrence of stress concentration in the restricting member 5.

[0021] As shown in Fig. 5, the restricting member 5 has a flexible plate-like main body 53 and a plurality of piece portions 54. The restricting member 5 is molded, for example, from an insulating synthetic resin. The main body 53 is a portion that extends along the electric wire W and has a length equal to that of the exterior member 4. Thus, the restricting member 5 extends from the first end 41 to the second end 42 of the exterior member 4. The shape of the main body 53 is an elongated rectangle.

[0022] The piece portion 54 is disposed on the edge portion 53a in the width direction of the main body 53. The illustrated restricting member 5 has a plurality of piece portions 54 on both edge portions 53a in the width direction of the main body 53. The piece portions 54 are erected from the edge portion 53a of the main body 53 in a direction perpendicular to the main body 53. In each edge portion 53a, the plurality of piece portions 54 are arranged in the extending direction of the main body 53. The piece portion 54 has an abutment portion 54a and a base portion 54b. The abutment portion 54a is a substantially rectangular piece. The abutment portion 54a is a portion that abuts against the adjacent abutment portion 54a to restrict the curved shape of the main body 53. The base portion 54b is a portion that connects the abutment portion 54a and the edge portion 53a of the main body 53. The length of the base portion 54b in the arrangement direction of the piece portions 54 is shorter than the length of the abutment portion 54a.

[0023] The restricting member 5 has a first end 51 and a second end 52. The first end 51 is one end in the length direction of the restricting member 5 and is disposed on the vehicle body 110 side. The second end 52 is the other end in the length direction of the restricting member 5 and is disposed on the sliding door 120 side.

[0024] When a first force F1 acts on the restricting member 5 in the bending direction, the abutting portions 54a of adjacent piece portions 54 abut against each other, restricting the curved shape of the main body 53. The piece portions 54 cause the main body 53 to extend in a substantially straight line against the first force F1. The piece portions 54 in the vicinity of the first end portion 51 of the restricting member 5 allow the main body 53 to be slightly curved and deformed by the first force F1. In other words, the restricting member 5 is configured to form a curved portion 56 that is gently curved in the vicinity of the first end portion 51 when the first force F1 acts on the restricting member 5.

[0025] When a second force F2 in the bending direction acts on the restricting member 5, adjacent piece portions 54 move away from each other. The piece portions 54 do not restrict the deformation of the main body 53, but allow the main body 53 to freely curve. Therefore, the restricting member 5 is configured to restrict the bending deformation of the exterior member 4 due to the first force F1, and to allow the bending deformation of the exterior member 4 due to the second force F2.

[0026] The first end 51 is provided with a held portion 55 that is held by the holding member 3. When viewed from the front, the shape of the held portion 55 is substantially U-shaped. The held portion 55 has a linear piece 55a connected to the end of the main body 53 and two linear pieces 55b connected to the ends of the piece portion 54.

[0027] The holding member 3 is a member that holds the first end portion 41 of the exterior member 4 and the first end portion 51 of the restricting member 5. The shape of the holding member 3 in this embodiment is substantially spherical. As shown in Fig. 6, the holding member 3 has a first member 31 and a second member 32. The first member 31 and the second member 32 are molded, for example, from an insulating synthetic resin.

[0028] The first member 31 and the second member 32 each have a hemispherical outer peripheral surface. In this embodiment, the first member 31 and the second member 32 are members of the same shape. The first member 31 and the second member 32 have a first engagement portion 33, a second engagement portion 34, a first holding portion 35, and a second holding portion 36. The first holding portion 35 holds a first end portion 41 of the exterior member 4. The first holding portion 35 is a groove portion having a substantially U-shaped cross section. The first holding portion 35 has a plurality of ribs 35a. The ribs 35a engage with an annular recess provided on the outer surface of the exterior member 4 to lock the first end portion 41.

[0029] The second holding portion 36 holds the held portion 55 of the regulating member 5. The held portion 55 is exposed to the outside from the first end portion 41 of the exterior member 4. The second holding portion 36 has a groove that fits with the piece portion 55b of the held portion 55.

[0030] The first engagement portion 33 and the second engagement portion 34 are configured to engage with each other. The illustrated first engagement portion 33 is a claw portion provided on the side surface of the first member 31 and the second member 32. The illustrated second engagement portion 34 is a piece having a frame shape, and is locked by the first engagement portion 33.

[0031] The first member 31 and the second member 32 engage with each other along the longitudinal direction LD of the exterior member 4. At this time, the first holding portion 35 of the first member 31 and the first holding portion 35 of the second member 32 sandwich the first end portion 41 of the exterior member 4 and hold the first end portion 41. The two first holding portions 35 hold the first end portion 41 such that the first end portion 41 cannot rotate relative to the holding member 3. In other words, the holding member 3 holds the first end portion 41 such that the first member 31 and the second member 32 always face each other in the longitudinal direction LD.

[0032] Additionally, the second holding portion 36 of the first member 31 and the second holding portion 36 of the second member 32 sandwich the held portion 55 of the regulating member 5 and hold the held portion 55. The first member 31 and the second member 32 hold the regulating member 5 so as not to rotate relative to the held portion 55 by fitting the groove of the second holding portion 36 into the held portion 55. The first member 31 and the second member 32 have an opening 37. The electric wire W is drawn out of the holding member 3 from the opening 37.

[0033] As shown in Fig. 3, the first protector 2 has a protector body 21 and a cover 22. The protector body 21 and the cover 22 are molded, for example, from an insulating synthetic resin. The protector body 21 has a wiring path 23 and a support portion 24. The wiring path 23 is a passage through which the electric wire W drawn out from the holding member 3 is wired. The support portion 24 supports the holding member 3 rotatably.

[0034] As shown in FIG. 7, the support part 24 is disposed at an end of the wiring passage 23 on the side of the sliding door 120. The support part 24 has a pair of ribs 25 having an arc-shaped support surface, and a connecting rib 26 having an arc-shaped support surface. The support part 24 forms an accommodation chamber for accommodating the holding member 3, and is configured to rotate the holding member 3 inside the accommodation chamber. The pair of ribs 25 are disposed parallel to each other with a gap therebetween. The connecting rib 26 is perpendicular to the ribs 25 and is connected to the two ribs 25. The support part 24 rotatably supports the holding member 3 by the ribs 25 and the connecting ribs 26.

[0035] The cover 22 is a member that engages with the protector body 21 to cover the wiring passage 23. As shown in FIG. 8, the cover 22 has a support portion 27 that corresponds to the support portion 24 of the protector body 21. The support portion 27 has a pair of ribs 28 having an arc-shaped support surface. The pair of ribs 28 are arranged parallel to each other with a gap between them. The support portion 27 is combined with the support portion 24 of the protector body 21 to form an accommodation chamber that accommodates the holding member 3.

[0036] As shown in FIG. 9, the rotating member 7 is a cylindrical member. The rotating member 7 is molded, for example, from an insulating synthetic resin. The rotating member 7 has a first shaft portion 71, a second shaft portion 72, and a cylindrical portion 73. The cylindrical portion 73 has a cylindrical shape and holds the second end portion 42 of the exterior member 4. The second end portion 52 of the restricting member 5 is located inside the second end portion 42. Therefore, the cylindrical portion 73 holds the second end portion 42 of the exterior member 4 and the second end portion 52 of the restricting member 5.

[0037] The first shaft portion 71 and the second shaft portion 72 are rotatably supported by the second protector 6. The first shaft portion 71 and the second shaft portion 72 are arranged coaxially. The first shaft portion 71 protrudes upward from the end of the tube portion 73. The first shaft portion 71 has a cylindrical shape and is connected to the tube portion 73. The electric wire W is drawn from the exterior member 4 through the first shaft portion 71 to the sliding door 120. The second shaft portion 72 protrudes downward from the end of the tube portion 73.

[0038] The tubular portion 73 holds the exterior member 4 and the restricting member 5 such that the longitudinal direction LD of the exterior member 4 is aligned with the axial direction of the shaft portions 71, 72. The rotating member 7 is supported by the second protector 6 such that the longitudinal direction LD is aligned with the vehicle vertical direction Z. The second protector 6 supports the shaft portions 71, 72 such that the central axis CX of the shaft portions 71, 72 is aligned with the vehicle vertical direction Z. In other words, the rotating member 7 is supported rotatably about the axis in the vehicle vertical direction Z.

[0039] The rotating member 7 holds the second end 42 so that the longitudinal direction LD is not inclined with respect to the vehicle up-down direction Z. In other words, the rotating member 7 can restore the orientations of the exterior member 4 and the regulating member 5 to their original orientations when the exterior member 4 and the regulating member 5 are temporarily twisted and deformed by the external force FV.

[0040] Fig. 10 shows a cross section taken along line XX in Fig. 1. In Fig. 10, the cover 22 is omitted in order to show the internal state of the first protector 2. As shown in Fig. 10, the restricting member 5 and the electric wire W are inserted inside the exterior member 4. The restricting member 5 is inserted into the exterior member 4 with the main body 53 oriented along the longitudinal direction LD of the exterior member 4. The piece portions 54 of the restricting member 5 face each other in the longitudinal direction LD.

[0041] The exterior member 4 and the restricting member 5 are disposed between the first protector 2 and the second protector 6 such that the longitudinal direction LD is along the vehicle vertical direction Z. When a user steps on the exterior member 4, an external force FV toward the lower side in the vehicle vertical direction Z acts on the exterior member 4. As a result, a moment M1 acts on the exterior member 4 at the stepped location. The holding member 3 rotates inside the first protector 2, thereby allowing the exterior member 4 and the restricting member 5 to deform due to the moment M1.

[0042] FIG. 11 shows the exterior member 4 and the restricting member 5 deformed by receiving the moment M1. The exterior member 4 and the restricting member 5 are deformed so that the longitudinal direction LD of the portion receiving the external force FV is along the horizontal direction. Therefore, the external force FV acts on the restricting member 5 along the plate thickness direction of the main body 53. As a result, the restricting member 5 is less likely to be damaged compared to the case where the external force FV acts along the longitudinal direction LD. When the restricting member 5 receives the external force FV along the longitudinal direction LD, stress concentration is likely to occur at the edge portion 53a of the main body 53. In contrast, when the external force FV is along the thickness direction of the main body 53, stress concentration is less likely to occur at the edge portion 53a. Therefore, the wiring structure 1 of this embodiment can improve the durability of the restricting member 5.

[0043] When the external force FV is no longer acting on the exterior member 4, the postures of the exterior member 4 and the regulating member 5 return to the posture shown in Fig. 10. As described with reference to Fig. 9, the rotating member 7 arranged on the sliding door 120 holds the exterior member 4 and the regulating member 5 so that the longitudinal direction LD is aligned with the vehicle up-down direction Z. Therefore, the exterior member 4 and the regulating member 5 can return to their original postures by their own elastic restoring forces.

[0044] The opening and closing operation of the sliding door 120 can encourage the exterior member 4 and the restricting member 5 to restore their postures. As shown in FIG. 2, the direction of curvature of the exterior member 4 changes according to the movement of the sliding door 120. When the sliding door 120 is in the fully closed position, a curved portion 43 is formed in the exterior member 4. When the sliding door 120 is in the fully open position, a curved portion 44 is formed in the exterior member 4. The two curved portions 43, 44 are curved in opposite directions. By deforming the exterior member 4 in this way, the posture of the exterior member 4 is corrected so that the longitudinal direction LD is aligned with the vehicle vertical direction Z.

[0045] The regulating member 5 is configured to regulate the curved shape of the exterior member 4, and is therefore capable of correcting any twist of the exterior member 4. The regulating member 5 is capable of correcting any twist of the exterior member 4 so that the longitudinal direction LD is aligned with the vehicle up-down direction Z by causing adjacent piece portions 54 to abut against each other.

[0046] Furthermore, the exterior member 4 and the restricting member 5 may bend downward when stepped on by a user. In this case, the bending is eliminated by the rigidity of the exterior member 4 and the electric wires W. Furthermore, the rotating member 7 restricts the positions of the second ends 42, 52 of the exterior member 4 and the restricting member 5, and promotes the elimination of the bending.

[0047] As described above, the wiring structure of the present embodiment includes the electric wire W, the cylindrical exterior member 4 through which the electric wire W is inserted, the restricting member 5, the holding member 3, the first protector 2, and the cylindrical rotating member 7. The electric wire W is arranged between the vehicle body 110 and the sliding door 120 of the vehicle 100. The exterior member 4 has a first end 41 which is an end on the vehicle body 110 side, and a second end 42 which is an end on the sliding door 120 side. The restricting member 5 is inserted into the exterior member 4 and restricts the curved shape of the exterior member 4. The holding member 3 is a spherical member that holds the first end 41 of the exterior member 4. The first protector 2 is disposed in the vehicle body 110 and rotatably supports the holding member 3. The rotating member 7 is disposed in the sliding door 120 and is supported rotatably around an axis in the vehicle vertical direction Z as a rotation center.

[0048] The restricting member 5 has a plate-shaped main body 53 and a plurality of pieces 54. The main body 53 is flexible and extends along the electric wire W. The plurality of pieces 54 are arranged on the edge 53a in the width direction of the main body 53 and are aligned in the extension direction of the main body 53. The restricting member 5 restricts the curved shape of the main body 53 by abutting the adjacent pieces 54. The cross-sectional shape of the exterior member 4 has a shape having a longitudinal direction LD and a lateral direction SD. The restricting member 5 is inserted into the exterior member 4 so that the width direction of the main body 53 is aligned with the longitudinal direction LD. In the wiring structure 1 of this embodiment, when an external force FV along the longitudinal direction LD acts on the exterior member 4, the exterior member 4 and the restricting member 5 can be deformed so as to receive the external force FV in the lateral direction SD. Therefore, the wiring structure 1 of this embodiment can suppress the occurrence of stress concentration in the restricting member 5.

[0049] The rotating member 7 has a tubular portion 73 that holds the second end 42 of the exterior member 4. The restricting member 5 extends from the first end 41 to the second end 42 of the exterior member 4. The tubular portion 73 holds the second end 42 such that the longitudinal direction LD in the cross-sectional shape of the exterior member 4 at the second end 42 is aligned with the vehicle vertical direction Z. The rotating member 7 of this embodiment can return the exterior member 4 and the restricting member 5 that have been deformed by an external force FV to their original positions.

[0050] The cross-sectional shape of the exterior member 4 in this embodiment is an ellipse with its major axis directed toward the main body 53 of the restricting member 5. Therefore, when an external force FV in the longitudinal direction LD acts, a moment M1 is likely to act on the exterior member 4 and the restricting member 5.

[0051] The regulating member 5 of this embodiment has a held portion 55 provided at the end portion on the vehicle body 110 side. The holding member 3 holds the held portion 55 so that the holding member 3 does not rotate with respect to the regulating member 5. This makes it difficult for relative twisting between the exterior member 4 and the regulating member 5 to occur.

[0052] The cross-sectional shape of the exterior member 4 is not limited to the elliptical shape shown in the example. If the cross-sectional shape of the exterior member 4 has the longitudinal direction LD, when an external force FV acts on the exterior member 4 and the restricting member 5, the exterior member 4 and the restricting member 5 are more likely to receive the external force FV at the wide portion.

[0053] The holding member 3 may hold the regulating member 5 via the exterior member 4. In this case, the held portion 55 of the regulating member 5 may be disposed inside the exterior member 4.
