[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] An embodiment will be described with reference to Figures 1 to 5. This embodiment relates to a cable routing structure. Figure 1 is a plan view of the cable routing structure according to the embodiment, Figure 2 is a cross-sectional view of the cable routing structure according to the embodiment, Figure 3 is a plan view of the protector according to the embodiment, Figure 4 is a plan view of the cable routing structure according to the embodiment, and Figure 5 is a cross-sectional view of the cable routing structure according to the embodiment. Figure 2 shows the II-II cross-section of Figure 1. Figure 5 shows the VV cross-section of Figure 4.

[0011] As shown in Figure 1, the wiring structure 1 of this embodiment is mounted on a vehicle 100 such as an automobile. The wiring structure 1 includes a protector 2, a rotating member 3, an exterior member 5, and electric wires W. The wiring structure 1 connects the vehicle body 110 and the sliding door 120 of the vehicle 100. The sliding door 120 moves relative to the vehicle body 110 along a first direction X. The first direction X is, for example, the longitudinal direction of the vehicle 100. The sliding door 120 may slide by the operation of a link mechanism connecting the vehicle body 110 and the sliding door 120. The sliding door 120 may slide while being guided by rails arranged on the vehicle body 110.

[0012] The protector 2 is positioned on the sliding door 120 and is held in place by the sliding door 120. The protector 2 is molded from, for example, an insulating synthetic resin. The protector 2 rotatably supports the rotating member 3. The rotating member 3 has a cylindrical portion 31 that holds the end of the exterior member 5. The tip of the cylindrical portion 31 protrudes outward from the protector 2.

[0013] A body protector 130 corresponding to the protector 2 is positioned on the vehicle body 110. The body protector 130 is molded from, for example, an insulating synthetic resin. The body protector 130 rotatably supports a rotating member 140. The rotating member 140 has a cylindrical portion 141 that holds the end of the exterior member 5. The cylindrical portion 141 protrudes outward from the body protector 130. When the sliding door 120 opens and closes, the protector 2 and the exterior member 5 move in a first direction X. The cylindrical portion 141 rotates while following the movement of the protector 2 and the exterior member 5.

[0014] The sliding door 120 faces the vehicle body 110 in a second direction Y. The second direction Y is, for example, the width direction of the vehicle 100. In the following description, in the second direction Y, the side of the vehicle body 110 relative to the sliding door 120 will be referred to as the vehicle body side Y1, and the side of the sliding door 120 relative to the vehicle body 110 will be referred to as the door side Y2.

[0015] The electric wire W is routed from the vehicle body 110 to the sliding door 120. More specifically, the electric wire W is inserted from the body protector 130 through the rotating member 140, the exterior member 5, the rotating member 3, and the protector 2, and then pulled out toward the sliding door 120. The exterior member 5 is a flexible cylindrical protective member, such as a corrugated tube. The exterior member 5 extends from the rotating member 140 of the vehicle body 110 to the rotating member 3 of the sliding door 120.

[0016] The sliding door 120 moves between a fully closed position P1 and a fully open position P3. In Figure 1, protector 2A shows protector 2 when the sliding door 120 is in the fully closed position P1, protector 2C shows protector 2 when the sliding door 120 is in the fully open position P3, and protector 2B shows protector 2 when the sliding door 120 is in the half-open position P2. Rotating members 3A, 3B, and 3C show rotating members 3 when the sliding door 120 is in each of the positions P1, P2, and P3.

[0017] The fully closed position P1 is the front end X1 within the moving range of the sliding door 120 along the first direction X. The fully open position P3 is the rear end X2 within the moving range of the sliding door 120 along the first direction X. The fully closed position P1 is the position of the sliding door 120 when the sliding door 120 closes the opening of the vehicle 100. The fully open position P3 is the position of the sliding door 120 when the sliding door 120 opens the opening.

[0018] The sliding door 120 moves from the fully closed position P1 via the half-open position P2 to the fully open position P3. When the sliding door 120 is in the fully closed position P1, the electric wire W and the exterior member 5 extend from the protector 2A along the first direction X toward the rear side X2. The cylindrical portion 31 of the rotating member 3A protrudes from the protector 2A toward the rear side X2.

[0019] When the sliding door 120 is in the fully closed position P1, the exterior member 5 and the electric wire W curve toward the door side Y2. That is, the wiring structure 1 of the present embodiment is configured to curve the electric wire W and the exterior member 5 toward the door side Y2 when the sliding door 120 is in the fully closed position P1. For example, when the sliding door 120 is in the fully closed position P1, the rotating member 140 of the vehicle body 110 is inclined with respect to the first direction X so as to move toward the door side Y2 as it goes toward the tip of the cylindrical portion 141. Thereby, the exterior member 5 and the electric wire W curve toward the door side Y2 between the vehicle body 110 and the rotating member 3. The curved exterior member 5 and electric wire W press the rotating member 3A toward the protector 2A by the force F1. Note that the rotating member 140 may be locked by the body protector 130 so as to be inclined obliquely forward when the sliding door 120 is in the fully closed position P1.

[0020] As will be described below, the wiring structure 1 of the present embodiment has a regulating structure 10 (see FIG. 5) that regulates the vibration of the rotating member 3 with respect to the protector 2 when the sliding door 120 is in the fully closed position P1. Thereby, the generation of knocking sound between the protector 2 and the rotating member 3 is suppressed.

[0021] As shown in FIG. 2, the protector 2 has a main body 6 and a cover 7. The main body 6 and the cover 7 are molded, for example, from an insulating synthetic resin. The main body 6 and the cover 7 face each other in the vehicle up-and-down direction Z. By assembling the cover 7 to the main body 6, a space for accommodating the rotating member 3 and the electric wire W is formed.

[0022] The rotating member 3 has a main body 8 and a cover 9. The main body 8 and the cover 9 are molded, for example, from an insulating synthetic resin. The main body 8 and the cover 9 face each other in the vehicle up-and-down direction Z. By assembling the cover 9 to the main body 8, a passage through which the electric wire W is inserted is formed.

[0023] The main body 8 has a bottom wall 83 that supports the electric wire W and a rotating shaft 84 that protrudes from the bottom wall 83. The rotating shaft 84 protrudes toward the side opposite to the cover 9 side. The cover 9 has a top wall 93 and a rotating shaft 94 that protrudes from the top wall 93. The top wall 93 faces the bottom wall 83 in the vehicle up-and-down direction Z. The rotating shaft 94 protrudes toward the side opposite to the main body 8 side. The rotating member 3 rotates relative to the protector 2 about the rotating shafts 84 and 94 as rotation centers.

[0024] The rotating member 3 has a side wall 32. The side wall 32 extends between the bottom wall 83 and the top wall 93 and is, for example, orthogonal to the bottom wall 83 and the top wall 93. The side wall 32 is located on the door side Y2 with respect to the electric wire W when the sliding door 120 is in the fully closed position P1. The side wall 32 is a wall portion that extends in the vehicle up-and-down direction Z and is, for example, erected from the bottom wall 83. However, the side wall 32 may be a part of the cover 9. In this case, the side wall 32 may be erected from the top wall 93 toward the vehicle up-and-down direction Z.

[0025] As shown in FIG. 3, the main body 6 of the protector 2 has a groove-shaped wiring path 60 in which the electric wire W is routed. The wiring path 60 has an inlet portion 60a and an outlet portion 60b. The inlet portion 60a is an end portion on the vehicle body 110 side in the wiring path 60 and is open toward the vehicle body side Y1 and the rear side X2. The rotating member 3 is disposed at the inlet portion 60a.

[0026] The outlet section 60b is the end through which the electric wire W is pulled out toward the sliding door 120. The outlet section 60b opens toward the upper side in the vehicle's vertical direction Z.

[0027] The cable routing 60 has a first side wall 61, a second side wall 62, and a bottom wall 63. The bottom wall 63 is a wall that supports the electric wire W from below. The two side walls 61 and 62 are erected from the widthwise ends of the bottom wall 63. The two side walls 61 and 62 face each other in the widthwise direction of the bottom wall 63.

[0028] The bottom wall 63 is provided with a support hole 63a that rotatably supports the rotating member 3. The support hole 63a is a recess that is recessed toward the lower side in the vertical direction Z of the vehicle, or a through hole that penetrates the bottom wall 63. The support hole 63a is located at the entrance portion 60a. The rotation shaft 84 of the rotating member 3 is inserted into the support hole 63a and is rotatably supported by the support hole 63a.

[0029] The main body 6 has a fixing portion 64 that is fixed to the sliding door 120. The fixing portion 64 has a through hole 64a into which a fastening member can be inserted. The fixing portion 64 is connected to the rear end X2 of the second side wall 62. The protector 2 is fixed to the sliding door 120 by a fastening member such as a bolt inserted into the through hole 64a. In the protector 2 fixed to the sliding door 120, the cable routing 60 extends along the first direction X. The entrance portion 60a of the cable routing 60 is located on the rear side X2, and the exit portion 60b is located on the front side X1. When the protector 2 is fixed to the sliding door 120, the second side wall 62 extends in the first direction X and is located on the door side Y2 relative to the bottom wall 63.

[0030] The main body 6 has an opposing surface 65. The opposing surface 65 faces the side surface 33 of the rotating member 3 when the sliding door 120 is in the fully closed position P1. The illustrated opposing surface 65 is the surface of the second side wall 62 facing the vehicle body side Y1. The opposing surface 65 is located on the door side Y2 with respect to the support hole 63a and extends in the first direction X.

[0031] As shown in Figure 2, the cover 7 has a top wall 73. The top wall 73 faces the bottom wall 63 of the main body 6 in the vehicle's vertical direction Z. The top wall 73 has a support hole 73a facing the support hole 63a. The support hole 73a is a recess that is recessed toward the upper side in the vehicle's vertical direction Z, or a through hole that penetrates the top wall 73. The support hole 73a rotatably supports the rotation axis 94 of the rotating member 3.

[0032] Figure 4 shows the protector 2A and the rotating member 3A when the sliding door 120 is in the fully closed position P1. In Figure 4, the cover 7 of the protector 2 and the cover 9 of the rotating member 3 are omitted in order to show the internal structure. When the sliding door 120 is in the fully closed position P1, the side surface 33 of the rotating member 3A faces the opposing surface 65 of the protector 2. The side surface 33 is the outer surface of the side wall 32 and faces the door side Y2.

[0033] As shown in Figure 5, the rotating member 3 of this embodiment is provided with a projection 34. The projection 34 protrudes from the side surface 33. The projection 34 is positioned to move closer to or away from the opposing surface 65 in accordance with the rotational movement of the rotating member 3. For example, the projection 34 is positioned on the side surface 33 of the cylindrical portion 31. The projection 34 is positioned to move closer to the opposing surface 65 when the sliding door 120 moves toward the fully closed position P1.

[0034] The shape of the projection 34 is tapered, with the width in the vehicle's vertical direction Z narrowing towards the tip in the projection direction. That is, in a cross section perpendicular to the axial direction of the rotating member 3, the shape of the projection 34 is tapered, with the width in the vehicle's vertical direction Z narrowing towards the door side Y2. The cross-sectional shape of the illustrated projection 34 is triangular, for example, an isosceles triangle. The projection 34 has two inclined surfaces 35. The inclined surfaces 35 are inclined surfaces that are tilted with respect to the vehicle's vertical direction Z. The illustrated inclined surfaces 35 are planes. The two inclined surfaces 35 are aligned in the vehicle's vertical direction Z. One of the two inclined surfaces 35, the one located relatively above, points diagonally upward. The other of the two inclined surfaces 35, the one located relatively below, points diagonally downward. In the cross section of Figure 5, the vertex formed by the two inclined surfaces 35 has an interior angle θ.

[0035] Figure 5 shows the rotating member 3 when the sliding door 120 is in the fully closed position P1. At this time, the side surface 33 of the rotating member 3 faces the opposing surface 65 of the protector 2. The opposing surface 65 has a recess 66. The recess 66 is configured to receive and lock the projection 34 of the rotating member 3. The restricting structure 10 of this embodiment includes the projection 34 and the recess 66.

[0036] When the sliding door 120 is in the fully closed position P1, the projection 34 of the rotating member 3 is positioned in the recess 66. That is, as the sliding door 120 moves toward the fully closed position P1, the rotating member 3 rotates so that the projection 34 moves toward the door side Y2, and the projection 34 is housed in the recess 66.

[0037] The shape of the recess 66 is such that its width in the vehicle's vertical direction Z narrows towards the bottom of the recess 66. That is, in a cross section perpendicular to the first direction X, the shape of the recess 66 is a tapered shape in which its width in the vehicle's vertical direction Z narrows towards the door side Y2. The exemplified cross-sectional shape of the recess 66 is triangular, for example, an isosceles triangle. The recess 66 may also be a groove extending in the first direction X.

[0038] The recess 66 has two support surfaces 67. The support surfaces 67 are inclined surfaces that are tilted with respect to the vehicle's vertical direction Z. The illustrated support surfaces 67 are planar. The two support surfaces 67 face each other in the vehicle's vertical direction Z. One of the two support surfaces 67, the one located relatively lower, faces diagonally upward. The other of the two support surfaces 67, the one located relatively upper, faces diagonally downward. The angle between the two support surfaces 67 is equal to, for example, the interior angle θ of the projection 34. In this case, the recess 66 can bring the two support surfaces 67 into surface contact with the two inclined surfaces 35 of the rotating member 3.

[0039] As shown in Figure 1, when the sliding door 120 is in the fully closed position P1, the rotating member 3A receives a force F1 from the exterior member 5 and the electric wire W. The curved exterior member 5 and the electric wire W exert a force F1 toward the door side Y2 on the cylindrical portion 31 of the rotating member 3A.

[0040] As shown in Figure 5, this force F1 presses the projection 34 toward the recess 66. In other words, the exterior member 5 and the electric wire W curve to press the projection 34 toward the recess 66. As a result, the projection 34 is locked by the recess 66, and the movement of the rotating member 3 along the vehicle's vertical direction Z is restricted. Consequently, vibration of the rotating member 3 is reduced, and the generation of knocking noises between the rotating member 3 and the protector 2 is suppressed.

[0041] In the cable routing structure 1 of this embodiment, since the projection 34 of the rotating member 3 has a tapered shape, the projection 34 is pushed to the back of the recess 66 by the force F1. For example, the projection 34 is pushed into the recess 66 to the furthest possible position it can be inserted into. As a result, the range of motion of the rotating member 3 in the vertical direction Z of the vehicle is narrowed, and vibration of the rotating member 3 is suppressed.

[0042] Furthermore, since the projection 34 is inserted all the way into the recess 66, the recess 66 can contact each of the pair of inclined surfaces 35 and lock the projection 34 in place. In other words, the recess 66 can lock the projection 34 from both sides in the vertical direction Z of the vehicle, effectively suppressing vibrations of the rotating member 3.

[0043] The recess 66 in this embodiment has a tapered shape corresponding to the shape of the projection 34. As a result, the projection 34 is sandwiched between the recess 66 from both sides in the vehicle's vertical direction Z. In other words, the recess 66 sandwiches the projection 34 between a pair of support surfaces 67. The two support surfaces 67 abut against the two inclined surfaces 35 of the rotating member 3, locking the projection 34 from both sides in the vehicle's vertical direction Z. Therefore, the movement of the projection 34 in the vehicle's vertical direction Z is restricted. This effectively suppresses vibrations of the rotating member 3.

[0044] The shape of the projection 34 and the shape of the recess 66 are not limited to those shown in the figures. For example, the shape of the projection 34 in the cross-section of Figure 5 may be trapezoidal. In other words, the cross-sectional shape of the projection 34 may be a triangular shape with the tip cut off.

[0045] The rotating member 3 may have multiple protrusions 34. For example, the rotating member 3 may have two protrusions 34 aligned in the vehicle's vertical direction Z. In this case, the shape of the two protrusions 34 may be a shape obtained by dividing the protrusion 34 in Figure 5 into two.

[0046] The restricting structure 10 may have a plurality of protrusions 34 and a plurality of recesses 66. In this case, one recess 66 engages with at least one protrusion 34 and restricts the movement of the protrusion 34 in the vehicle vertical direction Z. One recess 66 may restrict the upward movement of the protrusion 34, and another recess 66 may restrict the downward movement of the protrusion 34.

[0047] As described above, the wiring structure 1 of this embodiment includes an electric wire W routed between the vehicle body 110 and the sliding door 120 of the vehicle 100, a protector 2, a rotating member 3, and a restricting structure 10. The protector 2 is positioned on the sliding door 120 and has a wiring path 60 through which the electric wire W is routed. The rotating member 3 is a cylindrical member through which the electric wire W is inserted and is rotatably supported by the protector 2. The restricting structure 10 restricts the vibration of the rotating member 3 in the vehicle vertical direction Z when the sliding door 120 is in the fully closed position P1.

[0048] The protector 2 has an opposing surface 65 that faces the side surface 33 of the rotating member 3 when the sliding door 120 is in the fully closed position P1. The regulating structure 10 has a recess 66 in the opposing surface 65 and a tapered projection 34 that protrudes from the side surface 33 of the rotating member 3. The projection 34 is positioned in the recess 66 when the sliding door 120 is in the fully closed position P1. The electric wire W curves between the vehicle body 110 and the rotating member 3 so as to press the projection 34 toward the recess 66 when the sliding door 120 is in the fully closed position P1. The wiring structure 1 of this embodiment can suppress vibration of the rotating member 3 by pressing the projection 34 toward the recess 66 with the curved electric wire W.

[0049] The projection 34 of this embodiment has a pair of inclined surfaces 35 that are tilted with respect to the vehicle's vertical direction Z. One of the pair of inclined surfaces 35 faces upward in the vehicle's vertical direction Z, and the other faces downward in the vehicle's vertical direction Z. The recess 66 abuts against each of the pair of inclined surfaces 35 and locks the projection 34 in place. With this configuration, vibration of the rotating member 3 is effectively suppressed.

[0050] The recess 66 in this embodiment has a pair of support surfaces 67 that are inclined with respect to the vehicle's vertical direction Z. One of the pair of support surfaces 67 faces upward in the vehicle's vertical direction Z, and the other faces downward in the vehicle's vertical direction Z. The recess 66 sandwiches the projection 34 between the pair of support surfaces 67, restricting the movement of the projection 34 in the vehicle's vertical direction Z. With this configuration, vibration of the rotating member 3 is effectively suppressed.

[0051] The contents disclosed in the above embodiments can be combined and implemented as appropriate. [Explanation of Symbols]
