Note that the present invention is not limited to the embodiment. In addition, the components in the following embodiment include those that a person skilled in the art can easily imagine or that are substantially the same.

Fig. 3 shows a cross section taken along line III-III in Fig. 4.

[0011] As shown in Fig. 1, a 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 sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a member that slides along the vehicle front-rear direction X with respect to the opening 120a. The sliding body 210 of this embodiment is a plate-like member that closes or opens the opening 120a. The sliding body 210 may be glass that is configured to be able to transmit light.

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

[0014] The rail 220 is fixed to the vehicle body 110. The rail 220 extends in the vehicle front-rear direction X. The rail 220 supports a mechanism that moves the slide body 210, and guides this mechanism in the vehicle front-rear direction X. The rail 220 further supports the exterior member 30 to form a first extension portion 31 in the exterior member 30.

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

[0016] Conversely, when the slide body 210 moves from the fully open position to the fully closed position, the slide body 210 moves toward the front side X1 in the vehicle longitudinal direction X and moves 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 configure a wire harness that is wired between the vehicle body 110 and the slide body 210.

[0018] The first fixing part 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixing part 10 may be a protector that protects the electric wires W. The first fixing part 10 is molded, for example, from 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 part 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may be a protector that protects the electric wires W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 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 a cylindrical member that is elastically deformable. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded, for example, from 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 part 10 and a second end 30b held by the second fixing part 20. The first fixing part 10 holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 along the rail 220 in the vehicle front-rear direction X. The first fixing part 10 of the present embodiment holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b such 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 such 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 into 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 portion 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 portion 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 are curved in the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b. 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 sliding body 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 sliding body 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] 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.

[0028] The biasing member 50 of the present embodiment has a rigidity capable of pressing the exterior member 30 toward the sliding body 210. The biasing member 50 is a rod-shaped or plate-shaped member, and is elastically deformable. The biasing member 50 is made of metal or resin.

[0029] As shown in Fig. 3 and Fig. 4, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The shape of the urging member 50 illustrated is a flat plate shape. In the urging member 50, the cross-sectional shape perpendicular to the axial direction of the urging member 50 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 capable of supporting the multiple electric wires W.

[0030] The urging member 50 in Fig. 3 is disposed on the outer side with respect to the electric wire W. Therefore, at the curved portions 33, 34, the urging member 50 is located on the radially outer side with respect to the electric wire W. As shown in Fig. 3, the urging member 50 contacts the exterior member 30 and applies pressing forces F1, F2 to the exterior member 30 at the contact surface.

[0031] 4, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a curved U-shape or J-shape. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 in a state in which the biasing member 50 has a curved portion 54.

[0032] The biasing member 50 bent to have the curved portion 54 applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the slide body 210. The pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.

[0033] 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 etc., 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 facing the lower side Y2. When the cabin side surface 210a is a flat surface, the second extension portion 32 is formed in a straight line. 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.

[0034] 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 a rigidity that can constantly press the exterior member 30 toward the sliding body 210 and keep it in contact with it. Therefore, the wiring structure 1 of this embodiment can stabilize the shape of the exterior member 30. For example, the biasing member 50 can keep the exterior member 30 in contact with the sliding body 210 against an external force such as vibration generated during driving.

[0035] The urging member 50 may be disposed so as to be located radially inward of the electric wire W at the curved portion. FIG. 5 shows the urging member 50 disposed radially inward of the electric wire W. The urging member 50 located at the first extension portion 31 of the exterior member 30 applies a pressing force F1 to the exterior member 30 and the electric wire W. That is, the pressing force F1 of the urging member 50 is applied to the exterior member 30 via the electric wire W. The urging member 50 located at the second extension portion 32 of the exterior member 30 applies a pressing force F2 to the exterior member 30 and the electric wire W. That is, the pressing force F2 of the urging member 50 is applied to the exterior member 30 via the electric wire W.

[0036] When the urging member 50 is disposed on the inside relative to the electric wire W, an appropriate bend R is formed in the urging member 50, as described below. FIG. 6 shows the urging member 50 and the electric wire W as viewed from the width direction H. In FIG. 6, the urging member 50 shown by the dashed dotted line indicates the curved shape when the urging member 50 is bent alone. When the urging member 50 has high rigidity, the bend R of the urging member 50 becomes small when the urging member 50 is bent inside the narrow space Sp. In other words, the curved portion of the urging member 50 is likely to have a tapered shape.

[0037] When the electric wire W is disposed on the outside of the urging member 50, the electric wire W supports the curved portion of the urging member 50. The electric wire W can increase the bending R of the urging member 50 compared to when the urging member 50 is bent by itself. Therefore, the bending durability of the urging member 50 is improved.

[0038] The urging members 50 may be disposed both inside and outside the electric wire W. FIG. 7 shows urging members 50 disposed on both sides of the electric wire W. The wiring structure 1 shown in FIG. 7 has a first urging member 50A and a second urging member 50B. The first urging member 50A is disposed inside the electric wire W. The second urging member 50B is disposed outside the electric wire W. In other words, the electric wire W is sandwiched between the first urging member 50A and the second urging member 50B inside the exterior member 30.

[0039] When the urging members 50A, 50B are arranged on both sides of the electric wire W, the bend R of the electric wire W is stabilized as described below. Fig. 8 shows the shape of the electric wire W when one urging member 50 is arranged on the outer side of the electric wire W. As shown in Fig. 8, when the electric wire W is arranged on the inner side of the urging member 50, the electric wire W may be separated from the urging member 50 due to its own weight or the like.

[0040] Fig. 9 shows the shape of the electric wire W when one urging member 50 is arranged on the inside relative to the electric wire W. As shown in Fig. 9, when the electric wire W is arranged on the outside relative to the urging member 50, the electric wire W may become separated from the urging member 50 due to tolerance. When the electric wire W becomes separated from the urging member 50, the bend R of the electric wire W is likely to deviate from the target size.

[0041] By disposing the electric wire W between the two biasing members 50A, 50B, the bending R of the electric wire W is controlled to a target size. In addition, by generating a bending reaction force by the two biasing members 50A, 50B, it is possible to reduce the thickness of the biasing members 50A, 50B.

[0042] As described above, the wiring structure 1 of the present embodiment has the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, and the biasing member 50. The first fixing portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixing portion 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle front-rear direction X with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 has a first end portion 30a held by the first fixing portion 10 and a second end portion 30b held by the second fixing portion 20. The electric wire W and the biasing member 50 are inserted into the exterior member 30.

[0043] The biasing member 50 forms curved portions 33, 34 that are curved toward the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b of the exterior member 30. In the wiring structure 1 of the present embodiment, the biasing member 50 can stabilize the shapes of the curved portions 33, 34.

[0044] At the curved portions 33, 34 of the exterior member 30, the urging member 50 may be located radially inward with respect to the electric wire W. In this case, the electric wire W supports the curved portions of the urging member 50, and an appropriate bend R can be formed in the urging member 50.

[0045] The wiring structure 1 may have two urging members 50A and 50B. In the curved portions 33 and 34 of the exterior member 30, the first urging member 50A is located radially inward with respect to the electric wire W, and the second urging member 50B is located radially outward with respect to the electric wire W. With this configuration, the bending R of the electric wire W is controlled to a target value.

[0046] At the curved portions 33, 34 of the exterior member 30, the urging member 50 may be located radially outward with respect to the electric wire W. In this case, the pressing forces F1, F2 are transmitted from the urging member 50 to the exterior member 30 without passing through the electric wire W.

[0047] [Modifications of the embodiment] A modified example of the embodiment will be described. Fig. 10 is a plan view of a biasing member according to the modified example of the embodiment, Fig. 11 is a cross-sectional view of the biasing member according to the modified example of the embodiment, and Fig. 12 is a diagram for explaining the bend R of the biasing member. The modified example of the embodiment differs from the above embodiment in that, for example, the biasing member 50 has a curved cross-sectional shape. Fig. 11 shows a cross section taken along line XI-XI of Fig. 10.

[0048] As shown in Fig. 10, the urging member 50 is a plate-shaped member having an axial direction Ax. The axial direction Ax is the longitudinal direction of the urging member 50. The urging member 50 is, for example, a metal plate. As shown in Fig. 11, the cross-sectional shape of the urging member 50 perpendicular to the axial direction Ax is an arc shape. The cross section of the urging member 50 has an arc shape with a radius r. In the urging member 50 having a curved cross-sectional shape, the magnitude of the bend R is determined according to the radius r of the cross section.

[0049] 12, when the urging member 50 is bent by itself, a curved portion 53 is formed in the urging member 50. The radius R0 of the curved portion 53 corresponds to the cross-sectional radius r. When the cross-sectional radius r is small, the curved portion 53 having a small value of radius R0 is formed in the urging member 50, and when the cross-sectional radius r is large, the curved portion 53 having a large value of radius R0 is formed in the urging member 50. In other words, the value of radius R0 of the curved portion 53 can be controlled by the radius r.

[0050] The cross-sectional radius r is determined, for example, according to the distance in the vehicle vertical direction Y between the first end 30a and the second end 30b of the exterior member 30. The cross-sectional radius r may be determined corresponding to the second distance L2 at the fully open position shown in FIG. 2. FIG. 12 shows the urging member 50 folded back to form an arc-shaped curved portion 53. The value of the cross-sectional radius r is set, for example, so that when the urging member 50 is folded back as shown in FIG. 12, the urging member 50 forms a curved shape with the second distance L2 as a diameter. In other words, the design value of the cross-sectional radius r is determined so as to realize the following formula (1). R0=R2=L2 / 2 (1)

[0051] When the cross-sectional radius r is determined as described above, a curved portion 34 having a radius R2 is formed in the exterior member 30 when fully opened, as shown in Fig. 2. The size of the radius R2 at this time is determined by the radius r of the cross-section of the biasing member 50.

[0052] When the sliding body 210 is in the fully closed position, a curved portion 33 is formed in the exterior member 30 as shown in FIG. 1. The radius R1 of the curved portion 33 is smaller than the radius r of the cross section. The radius R1 of the curved portion 33 is determined by the first distance L1. That is, when the distance L between the first end 30a and the second end 30b is smaller than the second distance L2, the biasing member 50 forms a bend R according to the distance L. In this way, the biasing member 50 can make the bend R of the exterior member 30 the maximum size according to the distance L when the sunroof 200 is fully closed, fully opened, and opened / closed. Note that, in the sunroof 200 of the modified example, the sliding body 210 is moved so that the second distance L2 is larger than the first distance L1, similar to the sunroof 200 of the above embodiment.

[0053] The cross-sectional radius r may be determined, for example, in correspondence with the first distance L1 in the fully closed position shown in Fig. 1. In this case, the value of the cross-sectional radius r is set, for example, so that the biasing member 50 forms a curved shape having the first distance L1 as a diameter when the biasing member 50 is folded back as shown in Fig. 12. In other words, the design value of the cross-sectional radius r is determined so as to realize the following formula (2). R0=R1=L1 / 2 (2)

[0054] When the cross-sectional radius r is determined as described above, a curved portion 34 of radius R1 is formed in the exterior member 30 when fully open, as shown in Fig. 13. The size of the radius R1 of the curved portion 34 is determined by the cross-sectional radius r of the biasing member 50. When the sliding body 210 is in the fully open position, an inclined portion 35 is formed in the exterior member 30. The inclined portion 35 is a portion that extends from the curved portion 34 to the second fixing portion 20, and is inclined with respect to the vehicle front-rear direction X.

[0055] Furthermore, when the sliding body 210 is in the fully closed position, a curved portion 33 with a radius R1 is formed in the exterior member 30 as shown in Fig. 1. The size of the radius R1 of the curved portion 33 is determined by the radius r of the cross section.

[0056] When the cross-sectional radius r is determined so as to realize the formula (2), the wire harness can be minimized. That is, the electric wires W, the exterior member 30, and the biasing member 50 can be minimized.

[0057] Note that the actual value of the cross-sectional radius r may not coincide with the theoretical value that realizes the above formula (1) or formula (2). For example, in the biasing member 50, the cross-sectional radius r may deviate slightly from the theoretical value due to manufacturing tolerances, etc. In this case, the radii of the curved portions 33, 34 formed may deviate from the target radii R1, R2. In other words, the diameters of the curved portions 33, 34 may deviate from the first distance L1 and the second distance L2.

[0058] Even if the actual cross-sectional radius r coincides with the theoretical value, the radii of the curved portions 33, 34 that are formed may differ from the target radii R1, R2. That is, when the biasing member 50 is folded back, the radii of the curved portions 33, 34 that are actually formed may deviate from the target size.

[0059] In addition, the urging member 50 may have different cross-sectional radii r at different positions in the axial direction Ax. For example, the urging member 50 may be provided with a first portion that forms the curved portion 33 when fully closed and a second portion that forms the curved portion 34 when fully open. In this case, the cross-sectional radius r of the first portion may be a value that realizes formula (2). The cross-sectional radius r of the second portion may be a value that realizes formula (1).

[0060] As described above, the sliding body 210 of this embodiment moves in the vehicle vertical direction Y in addition to the vehicle front-rear direction X between the fully closed position where the opening 120a is closed and the fully open position where the opening 120a is opened. The distance in the vehicle vertical direction Y of the second end 30b relative to the first end 30a at the fully closed position is a first distance L1. The distance in the vehicle vertical direction Y of the second end 30b relative to the first end 30a at the fully open position is a second distance L2 different from the first distance L1.

[0061] The biasing member 50 is configured to form a curved portion having a curved shape with a diameter of the first distance L1, or is configured to form a curved portion having a curved shape with a diameter of the second distance L2. The biasing member 50 may be configured to be able to form both the curved portion 33 having a diameter of the first distance L1 and the curved portion 34 having a diameter of the second distance L2.

[0062] The exemplified biasing member 50 is a plate-shaped member. The cross-sectional shape of the biasing member 50 perpendicular to the axial direction Ax of the biasing member 50 is an arc shape. The value of the radius r of the arc shape is determined so that when the biasing member 50 is folded back, the biasing member 50 forms a curved shape with a diameter of the first distance L1, or is determined so that when the biasing member 50 is folded back, the biasing member 50 forms a curved shape with a diameter of the second distance L2.

[0063] When a value of the radius r that causes the urging member 50 to form a curved shape having a diameter equal to the first distance L1 is used, it is possible to minimize the exterior member 30 and the electric wire W. When a value of the radius r that causes the urging member 50 to form a curved shape having a diameter equal to the second distance L2 is used, it is possible to maximize the bend R of the exterior member 30 according to the distance L.

[0064] The means for forming the curved portion of a predetermined radius in the biasing member 50 is not limited to the value of the radius r of the cross section. For example, the biasing member 50 may have a main body and a restricting portion that restricts the shape of the curved portion formed in the main body. As an example, the restricting portion of the biasing member 50 may be formed of a superelastic alloy. In this case, a restricting portion that gives a curved shape of radius R1 may be arranged in a portion of the main body of the biasing member 50 that forms the curved portion 33. A restricting portion that gives a curved shape of radius R2 may be arranged in a portion of the main body of the biasing member 50 that forms the curved portion 34. The main body of the biasing member 50 can generate a repulsive force in the vehicle vertical direction Y while the curved shape is restricted by the restricting portion.

[0065] The contents disclosed in the above-mentioned embodiments and modifications can be implemented in appropriate combinations. [Explanation of symbols]
