[0003] In a routing structure with a rotating element, excessive bending of an electrical cable due to the rotation of the rotating element can adversely affect the durability of the electrical cable.

[0010] As in Fig. 1, a routing structure 1 of the present embodiment is mounted on a vehicle 100, such as an automobile. The routing structure 1 includes a protective device 2, a rotating member 3, an exterior member 4, and an electric cable W. The routing structure 1 couples a vehicle body 110 of the vehicle 100 to a sliding member 120. The sliding member 120 is, for example, a sliding door. The sliding member 120 moves relative to the vehicle body 110 along a first direction X. The first direction X is, for example, the front-rear direction of the vehicle 100. The sliding member 120 can slide due to the operation of a link mechanism that couples the vehicle body 110 to the sliding member 120. The sliding member 120 can slide while being guided by a rail arranged on the vehicle body 110.

[0011] The sliding element 120 moves between a first position P1 and a second position P2. The first position P1 is the first end point in the sliding range of the sliding element 120, and the second position P2 is the second end point in the sliding range of the sliding element 120. The first position P1 is, for example, a fully closed position of the sliding door. The second position P2 is, for example, a fully open position of the sliding door.

[0012] The protective device 2 is arranged on the vehicle body 110 of the vehicle 100. The protective device 2 is a cylindrical member having a routing path 50 along which the electrical cable W is routed. The protective device 2 is formed, for example, from an insulating resin.

[0013] The rotating element 3 is rotatably supported by the protective device 2. The rotating element 3 has a cylindrical portion 31 through which the electric cable W is inserted, and it is arranged within the laying path 50 of the protective device 2. The rotating element 3 rotates between a first rotational position and a second rotational position. Fig. 1 by a solid line represents the first rotational position of the rotary member 3. The first rotational position is a rotational position in which the cylindrical portion 31 is directed toward the sliding member 120 located at the first position P1. Fig. The position of the rotary member 3 indicated by the dashed line in FIG. 1 is the second rotational position. The second rotational position is a rotational position in which the cylindrical portion 31 is directed toward the sliding member 120 located at the second position P2.

[0014] The outer member 4 is a cylindrical protective member that encloses the electrical cable W. The outer member 4 is, for example, a bellows-shaped member known as a corrugated tube. The outer member 4 has one end held by the rotating member 3.

[0015] The outer element 4 has the other end held by a holding element 130 provided on the sliding element 120.

[0016] At least one electrical cable W is located in the installation structure 1. The electrical cable W is routed to the protective device 2, the rotating element 3, the outer element 4, and the holding element 130. The electrical cable W is connected to a device arranged on the sliding element 120. The electrical line W can include, for example, a power supply line and a communication line.

[0017] The holding element 130 is arranged on the sliding element 120 and moves together with the sliding element 120 in the first direction X. The holding element 130 is, for example, a pivotally supported rotor element. In this case, the holding element 130 is capable of allowing the outer element 4 to extend from the rotating element 3 to the holding element 130 in a substantially straight line.

[0018] As in Fig. 2, the protective device 2 has a lower cover 5 and an upper cover 6. The lower cover 5 has the routing path 50 with a groove shape in which the electric wire W is routed. The upper cover 6 engages with the lower cover 5 to cover the routing path 50. The routing path 50 has a first opening 51 and a second opening 52. The first opening 51 is an opening through which the electric wire W is pulled out toward the vehicle body 110. The second opening 52 is an opening through which the electric wire W is pulled out toward the sliding member 120.

[0019] The lower cover 5 has a through-hole 53 that rotatably supports the rotating member 3. The through-hole 53 is located near the second opening 52 in the routing path 50. The through-hole 53 extends through the lower cover 5 along the engagement direction in which the lower cover 5 is engaged with the upper cover 6. As shown in Fig. 3, the upper cover 6 has a recess 61. The recess 61 faces the through hole 53 of the lower cover 5. The upper cover 6 rotatably supports the rotary member 3 through the recess 61. As shown in Fig. As shown in Figure 2, an engagement portion 54 is provided on the outer surface of the lower cover 5. The upper cover 6 has an engagement portion 62 that engages with the engagement portion 54. The lower cover 5 and the upper cover 6 each have fastening portions 55 and 63 that are fastened to the vehicle body 110. The fastening portions 55 and 63 have through holes for inserting a fastening member, such as a bolt.

[0020] As in Fig. As shown in Figure 4, the rotary member 3 includes a first member 7 and a second member 8. The first member 7 and the second member 8 are molded, for example, from an insulating resin. The first member 7 has an opposing wall 70, a first side wall 71, and a second side wall 72. The second member 8 has an opposing wall 80, a first side wall 81, and a second side wall 82. The first member 7 and the second member 8 engage with each other while aligning their opposing walls 70 and 80 to face each other.

[0021] As in Fig. As shown in Figure 5, the first member 7 has a shaft portion 73. The shaft portion 73 is inserted into the through-hole 53 of the protector 2 and is rotatably supported by the through-hole 53. The shaft portion 73 protrudes from the opposite wall 70 toward the side opposite the side walls 71 and 72. The shaft portion 73 is arranged at a first end 70a of the opposite wall 70 in the longitudinal direction. The first end 70a is an end portion from which the electric wire W is drawn out toward the first opening 51 of the protector 2.

[0022] As in Fig. 4, the side walls 71 and 72 of the first member 7 are erected from the edge of the opposite wall 70. The opposite wall 70, the first side wall 71, and the second side wall 72 form a passage with a rectangular cross-section. The first side wall 71 of the present embodiment extends linearly. The second side wall 72 has a curved end portion. More specifically, the second side wall 72 is curved away from the first side wall 71 as it approaches the first end 70a of the opposite wall 70. The width of the opposite wall 70 varies depending on the curved shape of the second side wall 72 and becomes wider as it approaches the first end 70a. The first end 70a has an edge 70b of a substantially arcuate shape. The opposite wall 70 has a second end 70c provided with a rib 74 that locks the end of the outer member 4.The second end 70c is an end portion opposite the opposite wall 70 from the first end 70a.

[0023] The second element 8 has a shaft portion 83. The shaft portion 83 is inserted into the recess 61 of the protective device 2 and is rotatably supported by the recess 61. The shaft portion 83 protrudes from the opposite wall 80 toward the side opposite the side walls 81 and 82. The shaft portion 83 is arranged at a first end 80a of the opposite wall 80 in the longitudinal direction. The first end 80a is an end portion opposite the first end 70a of the first element 7.

[0024] The side walls 81 and 82 of the second element 8 are erected from the edge of the opposite wall 80. The opposite wall 80, the first side wall 81, and the second side wall 82 form a passage with a rectangular cross-section. The first side wall 81 extends linearly. The second side wall 82 has a curved end portion corresponding to the second side wall 72 of the first element 7. More specifically, the second side wall 82 is curved away from the first side wall 81 as it approaches the first end 80a of the opposite wall 80. Thus, the width of the opposite wall 80 becomes wider as it approaches the first end 80a. The first end 80a has an edge 80b with a substantially arcuate shape.

[0025] The first member 7 has an engaging portion 75. The second member 8 has an engaging portion 85 that engages with the engaging portion 75. The combination of the first member 7 and the second member 8 forms a rectangular tubular cylindrical portion 31. The electrical cable W is pulled out from the second end 70c toward the sliding member 120.

[0026] Fig. 6 illustrates the rotary member 3 in the first rotational position. The outer member 4 and the electrical cable W extend from the rotary member 3 toward the sliding member 120 at the first position P1. Fig. 7 illustrates the rotary member 3 in the second rotational position. The outer member 4 and the electric cable W extend from the rotary member 3 toward the sliding member 120 at the second position P2. The rotary member 3 of the present embodiment pivotally rotates about a shaft center CX. As described below, the position of the shaft center CX is determined to form a suitable bending radius R in the electric cable W.

[0027] Fig. 8 illustrates a standalone rotary member 3. The shaft center CX is the center shaft line of the shaft portion 83. The shaft portion 73 is arranged coaxially with the shaft portion 83. Thus, the shaft center CX is also the center shaft line of the shaft portion 73. The position of the shaft center CX is a position shifted from a center shaft line CL of the cylindrical portion 31. The position of the shaft center CX is set so that the length of the laying route of the electric cable W is the same both when the rotary member 3 is at the first rotation position and when the rotary member 3 is at the second rotation position.

[0028] In Fig. 9, a routing route W2 of the electric wire W in the case where the sliding member 120 is located at the second position P2 is indicated by a dashed-dotted line. The bending radius R of the electric wire W within the protector 2 varies depending on the direction in which the electric wire W is pulled out toward the sliding member 120. In the arrangement of the protector 2 of the present embodiment, the bending radius R of the electric wire W in the case where the sliding member 120 is located at the second position P2 is set smaller than in the case where the sliding member 120 is located at the first position P1. The routing route W2 is a target route and is set so that the bending radius R at a base point WB is equal to or larger than a predetermined value.In the case where the sliding element 120 moves, the bending direction of the electric cable W varies with respect to the base point WB.

[0029] Fig. 9 illustrates a wavy line direction WX of the base point WB. In this connection, in the case where a width Wd is shortened to minimize the size of the protective device 2, the deflection angle of the electric wire W relative to the wavy line direction WX tends to become uneven. More specifically, in the case where the sliding member 120 is located at the first position P1, the deflection angle of the electric wire W relative to the wavy line direction WX is a first angle θ1. In the case where the sliding member 120 is located at the second position P2, the deflection angle of the electric wire W relative to the wavy line direction WX is a second angle θ2. In the case of shortening the width Wd, the second angle θ2 becomes larger than the first angle θ1.

[0030] As described above, in the case where the deflection angle of the electric wire W becomes uneven, it is necessary to control the bending radius R of the electric wire W to prevent it from becoming too small in the case where the sliding member 120 is located at the second position P2.

[0031] Fig. 10 illustrates a rotary member 300 according to a comparative example. In the rotary member 300 of the comparative example, the shaft center CX is located on the shaft center line CL of the cylindrical portion 31. In a routing route W3 of the electric wire W formed by the rotary member 300 of the comparative example, the bending radius R of the electric wire W is small. This is because the path length from the first opening 51 to a tip 31a of the cylindrical portion 31 is shortened due to the reduction in the width Wd.

[0032] As in Fig. 11, in the laying structure 1 of the present embodiment, in the case where the rotary member 3 is located at the second rotational position, the shaft center CX is positioned on the side of the first opening 51 with respect to the center shaft line CL of the cylindrical portion 31. In other words, the shaft center CX is located at an eccentric position with respect to the center shaft line CL of the cylindrical portion 31. As shown in Fig. 11, a comparison line CL0 is the central wave line of the cylindrical portion 31 in the case where the rotary member 300 of the Fig. 10 is located at the second rotational position. In other words, the comparison line CL0 is the center shaft line of the cylindrical portion 31 in the case where the shaft center CX is set to the center shaft line CL.

[0033] As in Fig. As shown in Figure 11, when the rotating member 3 is at the second rotational position, the center wave line CL of the present embodiment is located farther away from the first opening 51 with respect to the reference line CL0. Thus, the routing structure 1 of the present embodiment allows for an increase in the bending radius R of the electric cable W within the protective device 2.

[0034] The position of the shaft center CX is preferably set so that, for example, the path length of the electric wire W at the first rotational position is equal to the path length of the electric wire W at the second rotational position. Here, the two path lengths are path lengths from the first opening 51 of the protector 2 to the tip 31a of the cylindrical portion 31. The path length at the second rotational position is set so that the bending radius R of the electric wire W within the protector 2 is equal to or greater than a predetermined value.

[0035] An example of a method for determining the position of the shaft center CX will now be described. Fig. 12 illustrates two designed routing routes W1 and W2. The routing route W1 is the routing route for the electric wire W when the sliding member 120 is located at the first position P1. The routing route W1 is determined based on the relative position of the holding member 130 with respect to the protector 2, the shape of the routing path 50, and the like. In the present embodiment, the holding member 130 is located in an extending direction D1 of the routing path 50 with respect to the protector 2 when the sliding member 120 is located at the first position P1. Thus, the electric wire W extends from the protector 2 along the extending direction D1. Consequently, the routing route W1 is slightly curved in the routing path 50.

[0036] When the sliding member 120 is located at the second position P2, the holding member 130 is positioned relative to the protective device 2 in a direction D2 that intersects with the extension direction D1. Thus, the electric wire W extends from the protective device 2 along the direction D2. In the present embodiment, the direction D2 intersects with the extension direction D1 at an angle close to a right angle. Thus, the routing route W2 is curved to significantly change the direction of the electric wire W in the routing path 50. The routing route W2 is set so that the bending radius R formed in the electric wire W is equal to or greater than a predetermined value R1.

[0037] Based on the routing routes W1 and W2, a target position of the rotary element 3 is set. Fig. 12 shows two positions 3A and 3B of the rotary member 3. Position 3A is the target position of the rotary member 3 when the sliding member 120 is located at the first position P1. In other words, position 3A is a position where the electric cable W is extended along the laying route W1. Position 3A is determined, for example, such that the center line of the laying route W1 and the center wave line CL of the cylindrical portion 31 are aligned with each other.

[0038] The position 3B is the target position of the rotary member 3 when the sliding member 120 is located at the second position P2. In other words, the position 3B is a position where the electric wire W is extended along the routing route W2. For example, the position 3B is determined so that the center line of the routing route W2 and the shaft center line CL of the cylindrical portion 31 are aligned with each other. The two positions 3A and 3B are set so that the length of the electric wire from the first opening 51 to the tip 31a of the cylindrical portion 31 is equal. The position of the shaft center CX is set so that the two positions 3A and 3B are compatible, as described below.

[0039] As in Fig. 13, the cylindrical portion 31 has two angled portions 31b and 31c. Fig. 13 illustrates a line segment L1 connecting the angled portion 31b at position 3A and the angled portion 31b at position 3B, and a perpendicular bisector B1 of the line segment L1. Further, a line segment L2 connecting the angled portion 31c at position 3A and the angled portion 31c at position 3B, and a perpendicular bisector B2 of the line segment L2 are illustrated. The shaft center CX is set at the intersection point of the two perpendicular bisectors B1 and B2. This arrangement causes the rotary member 3 to be positioned at the two target positions 3A and 3B.

[0040] As in Fig. 14, the shaft center CX may be arranged on the projection 32 in the case where the rotary member 3 has a projection 32. The Fig. The rotary member 3 shown in Figure 14 has the protrusion 32 protruding from the cylindrical portion 31. The protrusion 32 protrudes from the cylindrical portion 31 in a direction away from the shaft center line CL. The arrangement of the shaft center CX at the protrusion 32 increases the distance from the shaft center line CL to the shaft center CX.

[0041] As described above, the routing structure 1 of the present embodiment includes the protector 2 and the rotary member 3. The protector 2 is arranged on the vehicle body 110 of the vehicle 100 and has the routing path 50. The electric wire W connecting the vehicle body 110 and the sliding member 120 is routed in the routing path 50. The rotary member 3 is arranged in the routing path 50. The rotary member 3 has the cylindrical portion 31 through which the electric wire W is inserted and is rotatably supported by the protector 2. The routing path 50 has the first opening 51 through which the electric wire W is pulled out toward the vehicle body 110, and the second opening 52 through which the electric wire W is pulled out toward the sliding member 120 as the opposite.

[0042] The rotary member 3 rotates between a first rotational position and a second rotational position. The first rotational position is a rotational position in which the cylindrical portion 31 is directed toward the sliding member 120 when the sliding member 120 is oppositely located at the first position P1 in the sliding direction. The second rotational position is a rotational position in which the cylindrical portion 31 is directed toward the sliding member 120 when the sliding member 120 is oppositely located at the second position P2 in the sliding direction. The electric cable W is bent between the first opening 51 and the rotary member 3 when the rotary member 3 is oppositely located at the second rotational position.The shaft center CX of the rotary shaft that pivotally rotates the rotary member 3 is located on the first opening 51 side with respect to the center shaft line CL of the cylindrical portion 31 when the rotary member 3 is at the second rotation position. According to the routing structure 1 of the present embodiment, the bending radius R of the electric cable W can be adjusted within the protector 2 to prevent it from becoming too small.

[0043] The rotary member 3 may have the projection 32 projecting from the cylindrical portion 31 in a direction away from the shaft center line CL. In this case, the shaft center CX may be located at the projection 32. The projection 32 may be provided so as to form the intersection point of the two perpendicular bisectors B1 and B2 in Fig. 13. In other words, the projection 32 can be provided depending on the position of the desired shaft center CX.

[0044] In addition, the protective device 2 and the rotating element 3 can be arranged on the sliding element 120. Fig. 15 illustrates the routing structure 1, which includes the protection device 2 and the rotating member 3 arranged on the sliding member 120. The protection device 2 is arranged on the sliding member 120 and fixed to the sliding member 120. In this case, the electric wire W is pulled out from the first opening 51 of the routing path 50 toward the sliding member 120. Furthermore, the electric wire W is pulled out from the second opening 52 toward the vehicle body 110, as opposed to the first opening 51.

[0045] The holding member 130 is arranged on the vehicle body 110 and holds the end of the outer member 4. The holding member 130 is, for example, a pivotally supported rotor member. A vehicle body-side protection device 140 may be placed on the vehicle body 110, which rotatably supports the holding member 130. In this case, the electric cable W is drawn out from the vehicle body-side protection device 140 to a power source or the like.

[0046] The rotating element 3 is arranged in the routing path 50 of the protective device 2 and is rotatably supported by the protective device 2. The rotating element 3 rotates such that the outer element 4 is caused to extend toward the holding element 130.

[0047] In Fig. In Figure 15, the position of the rotary member 3 indicated by the solid line is the first rotation position. The first rotation position is a rotation position in which the cylindrical portion 31 is directed toward the vehicle body 110, as opposed to the case where the sliding member 120 is located at the first position P1 in the sliding direction. Specifically, in the first rotation position, the rotary member 3 causes the cylindrical portion 31 to face the holding member 130.

[0048] The position of the rotary member 3 indicated by the dashed line is the second rotational position. The second rotational position is a rotational position in which the cylindrical portion 31 is directed toward the vehicle body 110, as opposed to the case where the sliding member 120 is located at the second position P2 in the sliding direction. Specifically, in the second rotational position, the rotary member 3 causes the cylindrical portion 31 to face the holding member 130.

[0049] The electric cable W is bent between the first opening 51 and the rotary member 3 in the case where the rotary member 3 is at the second rotation position. As with respect to Fig.As described in FIG. 11, the shaft center CX of the rotary shaft for pivotally rotating the rotary member 3 is located on the first opening 51 side with respect to the center shaft line CL of the cylindrical portion 31 in the case where the rotary member 3 is located at the second rotation position. The routing structure 1 of the present embodiment can be set to prevent the bending radius R of the electric wire W inside the protector 2 from becoming too small in the case where the protector 2 and the rotary member 3 are arranged on the slide member 120.

[0050] Furthermore, the shape and arrangement of the protective device 2 are not limited to the illustrated shape and arrangement. Furthermore, the shape and arrangement of the rotating element 3 are not limited to the illustrated shape and arrangement. The sliding element 120 is not limited to a sliding door. The sliding element 120 may be other elements that are movable relative to the vehicle body 110.

[0051] The shaft portions 73 and 83, which rotatably support the rotating element 3, may be provided in the protective device 2. In this case, the rotating element 3 may be provided with a recess or a through hole into which the shaft portions 73 and 83 are inserted.

[0052] The details disclosed in the above embodiments may be implemented in suitable combinations.

[0053] In the routing structure according to an embodiment of the present invention, the shaft center of the rotary shaft that pivotally rotates the rotary member is located on the first opening side with respect to the center shaft line of the cylindrical portion, which is the case when the rotary member is at the second rotational position. According to the routing structure according to an embodiment of the present invention, providing the longer distance between the center shaft line of the cylindrical portion and the first opening at the second rotational position makes it possible to achieve the effects of reducing the degree of curvature of the electric cable.
