[0009] The cable routing structure according to an embodiment of the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention. Furthermore, the components in the following embodiments include those that are easily conceivable by those skilled in the art or that are substantially identical.

[0010] [Embodiment] Embodiments will be described with reference to Figures 1 to 11. This embodiment relates to a cable routing structure.

Figure 10 shows the XX cross-section of Figure 1.

[0011] The cable routing structure 1 shown in Figure 1 is mounted on a vehicle 100. The illustrated vehicle 100 is an automobile having a power source such as an engine or motor. As shown in Figures 1 to 3, the cable routing structure 1 of this embodiment includes a first protector 2, a holding member 3, an exterior member 4, a regulating member 5, a second protector 6, a rotating member 7, and an electric wire W. The electric wire W is routed between the vehicle body 110 and the sliding door 120 of the vehicle 100. The electric wire W is connected to a power source such as a battery or a control unit in the vehicle body 110. The electric wire W is connected to the device of the sliding door 120 in 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 longitudinal direction of the vehicle 100. The sliding door 120 slides while being guided by, for example, a rail positioned on the vehicle body 110. The sliding door 120 may also slide by the operation of a link mechanism connecting the vehicle body 110 and the sliding door 120.

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

[0014] The first protector 2 is a protector disposed on the vehicle body 110. The second protector 6 is a protector disposed on the slide door 120 and moves in the first direction X together with the slide 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 wire W. The exterior member 4 extends from the first protector 2 to the second protector 6. The exterior member 4 is a flexible cylindrical member and deforms following the movement of the slide 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 the present embodiment is configured such 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, the first end portion 41 of the exterior member 4 is held by the spherical holding member 3. The first protector 2 supports the holding member 3 so that the holding member 3 can rotate.

[0016] When the exterior member 4 is stepped on by a user, the holding member 3 rotates so as to receive a load by the wide surfaces of the exterior member 4 and the restricting member 5. Thereby, the occurrence of stress concentration is suppressed in the restricting member 5.

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

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

[0019] The exterior member 4 is positioned so that its longitudinal direction LD is aligned with the vertical direction of the vehicle. 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 be inclined with respect to the vertical direction of the vehicle. On the other hand, the first protector 2 supports the spherical retaining member 3 so as to allow the longitudinal direction LD to be inclined with respect to the vertical direction of the vehicle.

[0020] When the exterior member 4 is stepped on by a user, an external force FV in the longitudinal direction LD shown in Figure 4 acts on the exterior member 4. Because the cross-sectional shape of the exterior member 4 is elongated, a moment M1 is generated on the exterior member 4 that causes it to tip over. Due to the moment M1, the exterior member 4 and the regulating member 5 housed inside it twist and deform so that the stepped portion falls over. As a result, the exterior member 4 and the regulating member 5 can receive the external force FV over a wide surface, as shown in Figure 11. Therefore, the cable routing structure 1 of this embodiment can suppress the occurrence of stress concentration in the regulating member 5.

[0021] As shown in Figure 5, the regulating member 5 has a flexible plate-shaped body 53 and a plurality of segmented portions 54. The regulating member 5 is molded from, for example, an insulating synthetic resin. The body 53 is the portion that extends along the electric wire W and has a length equivalent to the length of the outer covering member 4. Therefore, the regulating member 5 extends from the first end 41 to the second end 42 of the outer covering member 4. The shape of the body 53 is an elongated rectangle.

[0022] The segmented portion 54 is positioned on the widthwise edge 53a of the main body 53. The illustrated restricting member 5 has multiple segmented portions 54 on both widthwise edges 53a of the main body 53. The segmented portions 54 are erected from the edge 53a of the main body 53 in a direction perpendicular to the main body 53. At each edge 53a, the multiple segmented portions 54 are aligned in the extending direction of the main body 53. The segmented portion 54 has a contact portion 54a and a base portion 54b. The contact portion 54a is a substantially rectangular piece. The contact portion 54a is the part that restricts the curvature of the main body 53 by contacting adjacent contact portions 54a. The base portion 54b is the part that connects the contact portion 54a and the edge 53a of the main body 53. The length of the base portion 54b in the direction of alignment of the segmented portions 54 is shorter than the length of the contact portion 54a.

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

[0024] When a first force F1 in the bending direction is applied to the restricting member 5, the contact portions 54a of adjacent segment portions 54 come into contact with each other, restricting the curvature of the main body 53. The segment portions 54 cause the main body 53 to extend in a substantially straight line against the first force F1. However, the segment portions 54 near the first end portion 51 of the restricting member 5 allow the main body 53 to be slightly curved due to the first force F1. That is, the restricting member 5 is configured to form a gently curving segment 56 near the first end portion 51 when the first force F1 is applied.

[0025] When a second force F2 in the bending direction is applied to the restricting member 5, adjacent segment portions 54 separate. The segment portions 54 do not restrict the deformation of the main body 53, but allow the main body 53 to undergo free bending deformation. 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 portion 51 is provided with a retained portion 55 that is held by the retaining member 3. When viewed from the front, the retained portion 55 has a roughly U-shape. The retained portion 55 has a straight piece 55a that connects to the end of the main body 53 and two straight pieces 55b that connect to the ends of the piece portion 54.

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

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

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

[0030] The first engaging portion 33 and the second engaging portion 34 are configured to engage with each other. The illustrated first engaging portion 33 is a claw provided on the side surfaces of the first member 31 and the second member 32. The illustrated second engaging portion 34 is a frame-shaped piece that is locked by the first engaging portion 33.

[0031] The first member 31 and the second member 32 engage with the exterior member 4 along its longitudinal direction LD. At this time, the first retaining portion 35 of the first member 31 and the first retaining portion 35 of the second member 32 clamp the first end portion 41 of the exterior member 4 and hold the first end portion 41. The two first retaining portions 35 hold the first end portion 41 in such a way that the first end portion 41 cannot rotate relative to the retaining member 3. In other words, the retaining 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] Furthermore, the second holding portion 36 of the first member 31 and the second holding portion 36 of the second member 32 clamp 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 that it does not rotate relative to the held portion 55 by fitting the groove of the second holding portion 36 with the held portion 55. The first member 31 and the second member 32 have an opening 37. The electric wire W is pulled out from the opening 37 to the outside of the holding member 3.

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

[0034] As shown in Figure 7, the support portion 24 is located at the end of the cable routing 23 on the side of the sliding door 120. The support portion 24 has a pair of ribs 25 having arc-shaped support surfaces and a connecting rib 26 having an arc-shaped support surface. The support portion 24 forms a housing chamber for housing the retaining member 3 and is configured to allow the retaining member 3 to rotate inside this housing chamber. The pair of ribs 25 are spaced apart and arranged parallel to each other. The connecting rib 26 is perpendicular to the ribs 25 and is connected to the two ribs 25. The support portion 24 rotatably supports the retaining member 3 by the ribs 25 and the connecting rib 26.

[0035] The cover 22 is a member that engages with the protector body 21 to cover the cable routing 23. As shown in Figure 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 spaced apart and arranged parallel to each other. When combined with the support portion 24 of the protector body 21, the support portion 27 forms a housing chamber for housing the retaining member 3.

[0036] As shown in Figure 9, the rotating member 7 is a cylindrical member. The rotating member 7 is molded from, for example, 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 regulating 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 regulating 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 cylindrical portion 73. The first shaft portion 71 has a cylindrical shape and communicates with the cylindrical portion 73. The electric wire W is drawn out 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 cylindrical portion 73.

[0038] The cylindrical portion 73 holds the exterior member 4 and the regulating member 5 such that the longitudinal direction LD of the exterior member 4 is aligned with the axial direction of the shaft portions 71 and 72. The rotating member 7 is supported by the second protector 6 such that its longitudinal direction LD is aligned with the vehicle's vertical direction Z. The second protector 6 supports the shaft portions 71 and 72 such that their central axes CX are aligned with the vehicle's vertical direction Z. In other words, the rotating member 7 is supported so as to be rotatable about the axis of rotation in the vehicle's vertical direction Z.

[0039] The rotating member 7 holds its second end 42 so that its longitudinal direction LD does not tilt with respect to the vehicle's vertical direction Z. In other words, the rotating member 7 can restore the exterior member 4 and the regulating member 5 to their original positions if they are temporarily twisted and deformed by an external force FV.

[0040] Figure 10 shows the XX cross-section of Figure 1. Note that in Figure 10, the cover 22 is omitted in order to show the internal state of the first protector 2. As shown in Figure 10, the regulating member 5 and the electric wire W are inserted inside the exterior member 4. The regulating member 5 is inserted into the exterior member 4 with its main body 53 aligned with the longitudinal direction LD of the exterior member 4. The segment portions 54 of the regulating member 5 face each other in the longitudinal direction LD.

[0041] The exterior member 4 and the restricting member 5 are positioned between the first protector 2 and the second protector 6 such that their longitudinal direction LD is aligned with the vehicle's vertical direction Z. When the exterior member 4 is stepped on by the user, an external force FV acting on the exterior member 4 is directed downwards in the vehicle's vertical direction Z. This causes a moment M1 to act on the exterior member 4 at the point where it is stepped on. The retaining member 3 rotates inside the first protector 2, thereby allowing deformation of the exterior member 4 and the restricting member 5 due to the moment M1.

[0042] Figure 11 shows the exterior member 4 and the restricting member 5 deformed under a moment M1. The exterior member 4 and the restricting member 5 are deformed so that the longitudinal direction LD at the point where the external force FV is applied is aligned with the horizontal direction. Therefore, the external force FV acts on the restricting member 5 along the thickness direction of the main body 53. As a result, the restricting member 5 is less susceptible to damage compared to the case where the external force FV acts along the longitudinal direction LD. When the restricting member 5 receives an external force FV along the longitudinal direction LD, stress concentration is likely to occur at the edge 53a of the main body 53. In contrast, when the external force FV is applied along the thickness direction of the main body 53, stress concentration at the edge 53a is less likely to occur. Therefore, the cable routing structure 1 of this embodiment can improve the durability of the restricting member 5.

[0043] When the external force FV ceases to act on the exterior member 4, the exterior member 4 and the regulating member 5 return to the positions shown in Figure 10. As explained with reference to Figure 9, the rotating member 7 positioned in the sliding door 120 holds the exterior member 4 and the regulating member 5 so that their longitudinal direction LD is aligned with the vehicle's vertical direction Z. Therefore, the exterior member 4 and the regulating member 5 can return to their original positions due to their respective elastic restoring forces.

[0044] Furthermore, the opening and closing operation of the sliding door 120 can help restore the posture of the exterior member 4 and the regulating member 5. As shown in Figure 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 and 44 are curved in opposite directions to each other. This deformation of the exterior member 4 corrects the posture of the exterior member 4 so that its longitudinal direction LD aligns with the vehicle's vertical direction Z.

[0045] The restricting member 5 is configured to restrict the curved shape of the exterior member 4, thereby correcting the twist of the exterior member 4. The restricting member 5 corrects the twist of the exterior member 4 so that its longitudinal direction LD is aligned with the vehicle's vertical direction Z, by having adjacent piece portions 54 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 resolved by the rigidity of the exterior member 4 and the electric wire W. In addition, the rotating member 7 restricts the posture of the second ends 42 and 52 of the exterior member 4 and the restricting member 5, thereby promoting the resolution of the bending.

[0047] As described above, the wiring structure of this embodiment comprises a wire W, a cylindrical exterior member 4 through which the wire W is inserted, a restricting member 5, a holding member 3, a first protector 2, and a cylindrical rotating member 7. The wire W is routed 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 the end on the vehicle body 110 side and a second end 42 which is the 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 positioned on the vehicle body 110 and rotatably supports the holding member 3. The rotating member 7 is positioned on the sliding door 120 and is rotatably supported about the axis in the vertical direction Z of the vehicle as the center of rotation.

[0048] The restricting member 5 has a plate-shaped main body 53 and a plurality of segmented portions 54. The main body 53 is flexible and extends along the electric wire W. The plurality of segmented portions 54 are arranged on the widthwise edge 53a of the main body 53 and aligned in the direction of extension of the main body 53. The restricting member 5 restricts the curvature of the main body 53 by the contact of adjacent segmented portions 54. The cross-sectional shape of the exterior member 4 has a longitudinal direction LD and a transverse direction SD. The restricting member 5 is inserted into the exterior member 4 so that the widthwise direction of the main body 53 is aligned with the longitudinal direction LD. In this embodiment, the wiring structure 1 can deform the exterior member 4 and the restricting member 5 so that when an external force FV acts on the exterior member 4 along the longitudinal direction LD, the external force FV is received in the transverse direction SD. Therefore, the wiring structure 1 in this embodiment can suppress the occurrence of stress concentration in the restricting member 5.

[0049] The rotating member 7 has a cylindrical portion 73 that holds the second end 42 of the exterior member 4. The regulating member 5 extends from the first end 41 to the second end 42 of the exterior member 4. The cylindrical portion 73 holds the second end 42 such that the longitudinal direction LD of the cross-sectional shape of the exterior member 4 is aligned with the vehicle's vertical direction Z. The rotating member 7 of this embodiment can return the exterior member 4 and the regulating member 5, which 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 oval shape with the direction of the main body 53 of the restricting member 5 as the longitudinal axis. Therefore, when an external force FV in the longitudinal direction LD is applied, a moment M1 is easily applied to the exterior member 4 and the restricting member 5.

[0051] The restricting member 5 in this embodiment has a retained portion 55 provided at the end on the side of the vehicle body 110. The retaining member 3 holds the retained portion 55 so that the retaining member 3 does not rotate relative to the restricting member 5. As a result, relative twisting of the exterior member 4 and the restricting member 5 is less likely to occur.

[0052] Furthermore, the cross-sectional shape of the exterior member 4 is not limited to the oval shape exemplified. If the cross-sectional shape of the exterior member 4 has a longitudinal direction LD, the exterior member 4 and the regulating member 5 will be more likely to receive the external force FV in their wider portions when the external force FV is applied.

[0053] The holding member 3 may hold the regulating member 5 via the outer casing member 4. In this case, the portion 55 of the regulating member 5 that is held may be located inside the outer casing member 4. The shape of the portion 55 that is held may be, for example, an oval shape corresponding to the shape of the outer casing member 4.

[0054] The contents disclosed in the above embodiments can be combined and implemented as appropriate. [Explanation of Symbols]
