Note that the present invention is not limited to the embodiment. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

FIG. 3 shows a cross section taken along line III-III of FIG. 4.

[0011] As shown in FIG. 1, the wiring structure 1 of the embodiment is applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, an automobile equipped with a power source such as a motor or an engine. The vehicle 100 has a vehicle body 110. The vehicle body 110 has a roof 120 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.

[0012] The vehicle 100 has a sunroof 200 that opens and closes the opening 120a. The sunroof 200 has a slider 210, a rail 220, and a wiring structure 1. The slider 210 is a member that slides relative to the opening 120a along the vehicle longitudinal direction X. In this embodiment, the slider 210 is a plate-like member that closes or opens the opening 120a. The slider 210 may be glass that is configured to allow light to pass through.

[0013] The sunroof 200 has a mechanism such as a link mechanism that moves the slider 210 along a predetermined path, and a drive source such as a motor that operates the mechanism. The sunroof 200 moves the slider 210 between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. Figure 1 shows the slider 210 in the fully closed position. Figure 2 shows the slider 210 in the fully open position.

[0014] The rail 220 is fixed to the vehicle body 110. The rail 220 is disposed below the sliding body 210 on the lower side Y2, and extends in the vehicle longitudinal direction X. The rail 220 supports a mechanism that moves the sliding body 210, and guides this mechanism in the vehicle longitudinal direction X. The rail 220 further supports the exterior member 30, and forms a first extending portion 31 on the exterior member 30.

[0015] The sunroof 200 of this embodiment moves the slider 210 along a path AR0 shown in Fig. 2. The movement of the slider 210 along the path AR0 includes movement along the vehicle longitudinal direction X and movement along the vehicle vertical direction Y. When the slider 210 moves from the fully closed position to the fully open position, as shown by arrow AR1 in Fig. 2, the slider 210 moves toward an upper side Y1 in the vehicle longitudinal direction Y and toward a rear side X2 in the vehicle longitudinal direction X.

[0016] Conversely, when the slider 210 moves from the fully open position to the fully closed position, the slider 210 moves toward the front side X1 in the vehicle longitudinal direction X and toward the lower side Y2 in the vehicle vertical direction Y.

[0017] 1 to 3, the wiring structure 1 has a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a biasing member 50. The exterior member 30 and the electric wire W constitute a wire harness that is wired between the vehicle body 110 and the sliding body 210.

[0018] The first fixing part 10 is a member fixed to the body 110 of the vehicle 100. The first fixing part 10 of this embodiment is fixed to the rail 220. The first fixing part 10 may be a protector that protects the electric wires W. The first fixing part 10 is molded from, for example, an insulating synthetic resin. The first fixing part 10 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0019] The second fixing portion 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing portion 20 may be a protector that protects the electric wires W. The second fixing portion 20 is molded from, for example, an insulating synthetic resin. The second fixing portion 20 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0020] The exterior member 30 is an elastically deformable cylindrical member. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded from, for example, an insulating synthetic resin. The exterior member 30 may have a bellows shape.

[0021] The exterior member 30 has a first end 30a held by the first fixing portion 10 and a second end 30b held by the second fixing portion 20. The first fixing portion 10 holds the first end 30a so that the exterior member 30 extends from the first fixing portion 10 along the rail 220 in the vehicle front-rear direction X. The first fixing portion 10 of the present embodiment holds the first end 30a so that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b so that the exterior member 30 extends from the second fixing portion 20 along the slide body 210 in the vehicle front-rear direction X. The second fixing portion 20 of the present embodiment holds the second end portion 30b so that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.

[0023] An electric wire W and a biasing member 50 are inserted through the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit body. The electric wire W drawn out from the first end 30a is connected to a power source or a control device arranged in the vehicle body 110. The electric wire W drawn out from the second end 30b is connected to a load arranged on the side of the sliding body 210. The load arranged on the sliding body 210 may be, for example, a lighting device, a light control film arranged on the glass of the sliding body 210, or other electric load.

[0024] As shown in FIGS. 1 and 2, the exterior member 30 has curved portions 33, 34 that curve in the vehicle longitudinal direction X between the first end 30a and the second end 30b. The curved portions 33, 34 are formed by a biasing member 50. The curved portion 33 shown in FIG. 1 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully closed position. The curved portion 33 has a radius R1. The curved portion 34 shown in FIG. 2 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W on which the curved portions 33, 34 are formed has a U-shape or a J-shape.

[0025] 1, when the slider 210 is in the fully closed position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0026] 2, when the slider 210 is in the fully open position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.

[0027] In the sunroof 200 of this embodiment, the second distance L2 at the fully open position is greater than the first distance L1 at the fully closed position. Therefore, the radius R1 of the curved portion 33 when the sliding body 210 is in the fully closed position is smaller than the radius R2 of the curved portion 34 when the sliding body 210 is in the fully open position. Furthermore, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed in the exterior member 30 when the sliding body 210 is in another position. In other words, the radius of the curved shape formed in the exterior member 30 is smallest when the sliding body 210 is in the fully closed position.

[0028] The second end 30b of the exterior member 30 moves together with the slider 210. At this time, the exterior member 30 follows the movement of the second fixing portion 20 while gradually changing the position where the curved shape is formed.

[0029] The biasing member 50 of this embodiment is a member that presses the exterior member 30 toward the slider 210. The biasing member 50 of this embodiment is a plate-shaped member that is elastically deformable. The biasing member 50 is made of metal or resin.

[0030] 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The urging member 50 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The urging member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the urging member 50 has a width that can support the multiple electric wires W.

[0031] 3 is disposed on the inner side with respect to the electric wire W. Therefore, at the curved portions 33 and 34, the urging member 50 is located on the inner side in the radial direction with respect to the electric wire W. As shown in FIG. 3, the urging member 50 applies pressing forces F1 and F2 to the exterior member 30.

[0032] 4, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a U-shaped or J-shaped curve. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 with a curved portion 54.

[0033] The biasing member 50 bent to have the curved portion 54 forms curved portions 33, 34 in the exterior member 30, and applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle's up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle's up-down direction Y, and presses the exterior member 30 toward the slider 210. The pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.

[0034] The pressing force F1 forms a first extension portion 31 in the exterior member 30. The pressing force F2 forms a second extension portion 32 in the exterior member 30. As shown in FIG. 2 and other figures, the second extension portion 32 is a portion that extends along the cabin-side surface 210a of the sliding body 210. The cabin-side surface 210a is a surface that faces the lower side Y2. When the cabin-side surface 210a is flat, the second extension portion 32 is formed in a linear shape. When the cabin-side surface 210a has a curved shape, the second extension portion 32 has a curved shape that follows the cabin-side surface 210a.

[0035] The biasing member 50 of this embodiment is configured to press the exterior member 30 toward the sliding body 210 when the sliding body 210 is in the fully closed position and when the sliding body 210 is in the fully open position. In other words, the biasing member 50 has enough rigidity to constantly press the exterior member 30 toward and keep it in contact with the sliding body 210. Therefore, the wiring structure 1 of this embodiment can stabilize the shape of the exterior member 30. The biasing member 50 can keep the exterior member 30 in contact with the sliding body 210 against external forces such as vibrations that occur during driving, for example.

[0036] As will be described below, the wiring structure 1 of this embodiment is configured to suppress the tapered shape of the urging member 50. First, the tapered shape formed on the urging member will be described.

[0037] 5 shows the tapered shape formed on the biasing member 150 of the comparative example. The biasing member 150 of the comparative example has a flat plate shape. The biasing member 150 is formed with a curved portion 151 and a straight portion 152. The straight portion 152 is a portion that extends linearly and is formed along each of the slider 210 and the rail 220.

[0038] The curved portion 151 has a tip portion 151a and two end portions 151b. The tip portion 151a is the center of the curved portion 151 and has a convex shape facing the vehicle longitudinal direction X. The end portions 151b are the ends of the curved portion 151 in the vehicle vertical direction Y and are portions that connect to the straight portion 152. The curved portion 151 has a tapered shape. More specifically, the shape of the curved portion 151 is such that the bending radius becomes smaller as it approaches the tip portion 151a from the end portions 151b.

[0039] 5 shows an imaginary circle IC. The imaginary circle IC is a circle whose diameter is the distance L0 from the rail 220 to the slider 210 in the vehicle up-down direction Y. The bending radius of the tip end 151a is smaller than the radius of the imaginary circle IC. In the curved portion 151 having a tapered shape, the bending radius of the tip end 151a is smaller than the bending radius of the end end 151b. When the distance L0 from the rail 220 to the slider 210 is small, such a tapered shape is likely to be formed in the curved portion 151.

[0040] As will be described below, the urging member 50 of this embodiment has a wavy portion 53. The wavy portion 53 is provided in a portion that forms a curved portion with respect to the exterior member 30. FIG. 6 shows a side view of the urging member 50 as viewed from the width direction of the urging member 50. The wiring structure 1 is arranged, for example, such that the width direction H of the exterior member 30 and the urging member 50 coincides with the vehicle width direction of the vehicle 100.

[0041] 6, a wavy portion 53 is provided over the entire range from the first end 50a to the second end 50b. The first end 50a is an end corresponding to the first end 30a of the exterior member 30. The second end 50b is an end corresponding to the second end 30b of the exterior member 30. The wavy portion 53 has a wave shape formed at a predetermined pitch. In the urging member 50 arranged along the electric wire W, the unevenness of the wavy portion 53 is repeated along the extending direction Ex of the electric wire W.

[0042] The biasing member 50 arranged along the electric wire W has an orthogonal direction Ot perpendicular to the extending direction Ex of the electric wire W. The orthogonal direction Ot is perpendicular to both the longitudinal direction and the width direction of the biasing member 50. The wavy portion 53 has a plurality of first peaks 53a and a plurality of second peaks 53b. In the wavy portion 53, the first peaks 53a and the second peaks 53b are alternately arranged. The first peaks 53a have a convex shape directed toward a first side S1 perpendicular to the extending direction Ex. The second peaks 53b have a convex shape directed toward a second side S2 perpendicular to the extending direction Ex.

[0043] When viewed in the width direction of the urging member 50, the first peak portion 53a has a tapered shape that narrows toward the tip of the first side S1. When viewed in the width direction of the urging member 50, the second peak portion 53b has a tapered shape that narrows toward the tip of the second side S2. The first peak portion 53a and the second peak portion 53b shown in FIG. 6 are substantially triangular. That is, the illustrated wavy portion 53 has a triangular wave-like shape when viewed in the width direction of the urging member 50. The first peak portion 53a and the second peak portion 53b are, for example, arranged at equal intervals.

[0044] FIG. 7 shows a wavy portion 53 that forms a curved portion 54. When a bending moment M1 acts on the wavy portion 53, the wavy portion 53 deforms to form an arc shape. At this time, the wavy portion 53 deforms so that the pitch p1 of the first peaks 53a increases and the pitch p2 of the second peaks 53b decreases. This deformation allows the wavy portion 53 to flexibly deform in response to the moment M1. More specifically, the wavy portion 53 is less likely to experience variations in the distribution of the reaction force against the moment M1.

[0045] For example, in the biasing member 150 of the comparative example, one of the reasons why the curved portion 151 is tapered is thought to be that the reaction force against the moment M1 is large at the distal end 151b. In the biasing member 50 of this embodiment, the reaction force at the distal end 54b of the curved portion 54 is suppressed, thereby suppressing the tapered shape of the curved portion 54. Furthermore, in the curved portion 54, a large difference is unlikely to occur between the reaction force at the tip end 54a against the moment M1 and the reaction force at the distal end 54b against the moment M1. Therefore, the biasing member 50 of this embodiment can suppress the tapered shape of the curved portion 54.

[0046] The pitch of the first peaks 53a and the second peaks 53b in the wavy portion 53 is determined so as to appropriately suppress the tapering shape of the curved portion 54. The wavy portion 53 is formed, for example, so that the curved portion 54 has a plurality of first peaks 53a and a plurality of second peaks 53b.

[0047] It should be noted that the range in which the wavy portion 53 is provided in the urging member 50 is not limited to the entire range from the first end 50a to the second end 50b. In the urging member 50 shown in Fig. 8, the wavy portion 53 is provided in a portion of the urging member 50. More specifically, the wavy portion 53 is provided in a range 50c that forms the curved portion 33 when fully closed. In the urging member 50 in Fig. 8, the portion other than the range 50c that forms the curved portion 33 has a flat plate shape.

[0048] 9 shows a state in which the urging member 50 of FIG. 8 forms a curved portion 33 in the exterior member 30. When the sliding body 210 is in the fully closed position, the distance from the sliding body 210 to the rail 220 in the vehicle up-down direction Y is smallest. At this time, the tapered shape of the curved portion 54 of the urging member 50 is suppressed, thereby suppressing a decrease in the bending durability of the electric wire W.

[0049] The urging member 50 may have a plurality of wave-shaped portions 53. Fig. 10 shows a urging member 50 having a plurality of wave-shaped portions 53. The urging member 50 of Fig. 10 has a main plate-shaped member 50M and an additional plate-shaped member 50X. The main plate-shaped member 50M has wave-shaped portions 53 over the entire area, similar to the urging member 50 of Fig. 6. The main plate-shaped member 50M has a region 50d that forms the curved portion 34 when fully open.

[0050] The additional plate-shaped member 50X has a wavy portion 53. The wavy portion 53 of the additional plate-shaped member 50X has a plurality of first peaks 53a and a plurality of second peaks 53b. The first peaks 53a and the second peaks 53b are alternately arranged. The additional plate-shaped member 50X is overlapped with a portion of the main plate-shaped member 50M. The additional plate-shaped member 50X is overlapped, for example, in the area 50d that forms the curved portion 34. In other words, the urging member 50 in FIG. 10 forms the curved portion 34 by two wavy portions 53.

[0051] 11 shows a state in which the urging member 50 of FIG. 10 forms the curved portion 34. When the sliding body 210 is in the fully open position, the distance from the sliding body 210 to the rail 220 is greater than when the sliding body 210 is in the fully closed position. At this time, the curved portion 54 is formed by two wavy portions 53, thereby ensuring a sufficient pressing force F2.

[0052] The shapes of the first peaks 53a and the second peaks 53b of the wavy portion 53 are not limited to the shapes illustrated in FIG. 6. The peaks 53a and 53b may have a triangular shape with rounded apexes as shown in FIG. 6. The wavy portion 53 may have curved peaks 53a and 53b as shown in FIG. 12, for example. The peaks 53a and 53b have a curved shape with rounded apexes of a triangular wave. The shape of the wavy portion 53 when viewed in the width direction of the urging member 50 may be a sine wave shape.

[0053] As described above, the wiring structure 1 of this embodiment includes the first fixed portion 10, the second fixed portion 20, the exterior member 30, the electric wire W, and the plate-shaped biasing member 50. The first fixed portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixed portion 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle longitudinal direction X relative to an opening 120a provided in a roof 120 of the vehicle body 110. The exterior member 30 has a first end portion 30a held by the first fixed portion 10 and a second end portion 30b held by the second fixed portion 20. The electric wire W and the biasing member 50 are inserted through the exterior member 30. The biasing member 50 forms a curved portion that curves in the vehicle longitudinal direction X between the first end portion 30a and the second end portion 30b of the exterior member 30.

[0054] The urging member 50 has a wavy portion 53 provided in a portion forming a curved portion. The wavy portion 53 has a plurality of first peaks 53a and a plurality of second peaks 53b. The first peaks 53a and the second peaks 53b are alternately arranged along the extending direction Ex of the electric wire W. When viewed in the width direction of the urging member 50, the first peaks 53a have a convex shape extending toward a first side S1 perpendicular to the extending direction Ex. When viewed in the width direction of the urging member 50, the second peaks 53b have a convex shape extending toward a second side S2 opposite the first side S1. According to the wiring structure 1 of this embodiment, the flexible wavy portion 53 forms a curved portion in the exterior member 30, thereby preventing the urging member 50 from tapering.

[0055] When viewed in the width direction of the urging member 50, the first peak 53a has a tapered shape that narrows toward the tip of the first side S1. When viewed in the width direction of the urging member 50, the second peak 53b has a tapered shape that narrows toward the tip of the second side S2. The wavy portion 53 having such a shape can be easily deformed to change the pitch p1 and the pitch p2.

[0056] The exterior member 30 is not limited to a so-called corrugated tube, but may be a braided tube or any other member used as an exterior member.

[0057] The biasing member 50 may be disposed on the outer side relative to the electric wire W. That is, the biasing member 50 may be disposed on the outer side of the electric wire W in the curved portions 33, 34 in the radial direction.

[0058] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
