Figure 3 Show Figure 4 Section III-III.

[0041] like Figure 1 As shown, wiring structure 1 of the embodiment is applied to sunroof 200 of vehicle 100. Vehicle 100 is, for example, an automobile equipped with a power source such as a motor or an engine. Vehicle 100 includes a vehicle body 110. Vehicle body 110 includes a roof 120 covering the vehicle interior. Roof 120 includes an opening 120a that opens upward.

[0042] Vehicle 100 includes a sunroof 200 that opens and closes an opening 120a. Sunroof 200 includes a slider 210, a rail 220, and a wiring structure 1. Slider 210 slides relative to opening 120a in the vehicle front-rear direction X. In this embodiment, slider 210 is a plate-shaped member that closes or opens opening 120a. Slider 210 may also be made of glass that allows light to pass through.

[0043] The sunroof 200 has a mechanism such as a link mechanism that moves the slider 210 along a predetermined path, and a driving 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 The sliding body 210 is shown in the fully closed position. Figure 2 The slider 210 is shown in the fully open position.

[0044] The rail 220 is fixed to the vehicle body 110 and extends in the vehicle longitudinal direction X. The rail 220 supports the mechanism that moves the slider 210 and guides the mechanism in the vehicle longitudinal direction X. The rail 220 also supports the exterior member 30 and forms a first extension portion 31 on the exterior member 30 .

[0045] The sunroof 200 of this embodiment makes the sliding body 210 move along the Figure 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 in FIG. Figure 2 As indicated by a middle arrow AR1 , the slider 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.

[0046] In contrast, 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.

[0047] like Figures 1 to 3 As shown, the wiring structure 1 includes a first fixing portion 10, a second fixing portion 20, an exterior member 30, wires W, and a biasing member 50. The exterior member 30 and the wires W constitute a wiring harness routed between the vehicle body 110 and the slider 210.

[0048] The first fixing portion 10 is a component fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 may also be a protector for protecting the electric wire W. The first fixing portion 10 is molded from, for example, an insulating synthetic resin. The first fixing portion 10 has a space for routing the electric wire W and a retaining structure for retaining the exterior member 30.

[0049] The second fixing portion 20 is fixed to the slider 210 of the sunroof 200. The second fixing portion 20 may also serve as a protector for the electric wires W. The second fixing portion 20 is molded, for example, from an insulating synthetic resin. The second fixing portion 20 provides space for routing the electric wires W and includes a retaining structure for retaining the exterior member 30.

[0050] The exterior member 30 is an elastically deformable cylindrical member. For example, the exterior member 30 is a member called a bellows. For example, the exterior member 30 is molded from an insulating synthetic resin. The exterior member 30 may also have a corrugated shape.

[0051] 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 first fixing portion 10 holds the first end portion 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. In this embodiment, the first fixing portion 10 holds the first end portion 30a so that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0052] 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 slider 210 in the vehicle longitudinal direction X. The second fixing portion 20 of this 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.

[0053] An electrical wire W and a force-applying member 50 are inserted through the exterior member 30. The electrical wire W is, for example, a sheathed wire having twisted wires and a sheath. The electrical wire W may be a flat wiring material, a printed circuit, or another circuit structure. The electrical wire W extending from the first end 30a is connected to a power supply or control device located on the vehicle body 110. The electrical wire W extending from the second end 30b is connected to a load located on the side of the slider 210. The load located on the slider 210 may be, for example, a lighting device, a dimming film on the glass of the slider 210, or another electrical load.

[0054] like Figure 1 and Figure 2 As shown, the exterior member 30 has bent portions 33 and 34 bent in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b . Figure 1The curved portion 33 shown is a curved portion formed on the exterior member 30 when the slider 210 is in the fully closed position. The curved portion 33 has a radius R1. Figure 2 The curved portion 34 shown is formed on the exterior member 30 when the slider 210 is in the fully open position. The curved portion 34 has a radius R2. The wire W formed with the curved portions 33 and 34 has a U-shape or a J-shape.

[0055] like Figure 1 As shown, when the slider 210 is in the fully closed position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is a first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0056] like Figure 2 As shown, when the slider 210 is in the fully open position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is a second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.

[0057] The second end portion 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.

[0058] The urging member 50 of this embodiment has rigidity sufficient to press the exterior member 30 toward the slider 210. The urging member 50 is a rod-shaped or plate-shaped member that is elastically deformable and is formed of metal or resin.

[0059] like Figure 3 and Figure 4 As shown, the exterior member 30 of this embodiment has a rectangular cross-section. The exemplary force-applying member 50 is flat. The force-applying member 50 has a rectangular cross-section perpendicular to its axial direction. The force-applying member 50 extends from one end to the other in the width direction H within the interior space of the exterior member 30. The force-applying member 50 faces each of the plurality of wires W in the vehicle vertical direction Y. In other words, the force-applying member 50 has a width sufficient to support the plurality of wires W.

[0060] Figure 3 The urging member 50 is arranged outside the wire W. Therefore, in the curved portions 33 and 34, the urging member 50 is located outside the wire W in the radial direction. Figure 3 As shown, the urging member 50 is in contact with the exterior member 30 and applies pressing forces F1 and F2 to the exterior member 30 at the contact surface.

[0061] like Figure 4As shown, the exterior member 30 , the wire W, and the urging member 50 are arranged in a state bent into a U-shape or a J-shape. That is, the urging member 50 extends from the first fixing portion 10 to the second fixing portion 20 with a bent portion 54 .

[0062] The biasing member 50, which is bent to have a curved portion 54, applies a pressing force F1 and a pressing force F2 to the exterior member 30. The pressing force F1 is a force in the vehicle vertical direction Y, pressing the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle vertical direction Y, pressing the exterior member 30 toward the slider 210. The pressing forces F1 and F2 are restoring forces generated by the bent biasing member 50.

[0063] The pressing force F1 forms a first extension portion 31 on the exterior member 30. The pressing force F2 forms a second extension portion 32 on the exterior member 30. Figure 2 As shown in FIG. 1 , the second extension portion 32 extends along the vehicle cabin-side surface 210a of the slider 210. The vehicle cabin-side surface 210a faces the lower side Y2. If the vehicle cabin-side surface 210a is flat, the second extension portion 32 is formed in a straight line. If the vehicle cabin-side surface 210a is curved, the second extension portion 32 has a curved shape that follows the vehicle cabin-side surface 210a.

[0064] The biasing member 50 of this embodiment is configured to press the exterior member 30 toward the slider 210 when the slider 210 is in the fully closed position and when the slider 210 is in the fully open position. In other words, the biasing member 50 has sufficient rigidity to constantly press the exterior member 30 toward the slider 210, ensuring contact therewith. Therefore, the wiring structure 1 of this embodiment stabilizes the shape of the exterior member 30. The biasing member 50 can maintain contact between the exterior member 30 and the slider 210, overcoming external forces such as vibrations generated during driving, for example.

[0065] Alternatively, the biasing member 50 may be arranged at a position radially inward of the wire W in the curved portion. Figure 5 , the urging member 50 is shown disposed on the inner side of the wire W. The urging member 50 located on the first extension portion 31 of the exterior member 30 applies a pressing force F1 to the exterior member 30 and the wire W. That is, the pressing force F1 of the urging member 50 is applied to the exterior member 30 via the wire W. The urging member 50 located on the second extension portion 32 of the exterior member 30 applies a pressing force F2 to the exterior member 30 and the wire W. That is, the pressing force F2 of the urging member 50 is applied to the exterior member 30 via the wire W.

[0066] When the urging member 50 is arranged on the inner side with respect to the electric wire W, as described below, an appropriate curvature radius R is formed on the urging member 50. Figure 65 shows the biasing member 50 and the wire W viewed from the width direction H. Figure 6 In the figure, the dot-dash line of the force applying member 50 represents the curved shape of the force applying member 50 when bent alone. If the force applying member 50 has high rigidity, the radius of curvature R of the force applying member 50 decreases when it bends within the narrow space Sp. In other words, the curved portion of the force applying member 50 tends to have a tapering shape.

[0067] When the wire W is arranged outside the urging member 50, the wire W supports the bent portion of the urging member 50. Compared to when the urging member 50 is bent alone, the wire W can increase the curvature radius R of the urging member 50. Therefore, the bending durability of the urging member 50 is improved.

[0068] The urging member 50 may be arranged on both the inner side and the outer side of the wire W. Figure 7 The biasing members 50 arranged on both sides of the electric wire W are shown in FIG. Figure 7 The wiring structure 1 shown includes a first biasing member 50A and a second biasing member 50B. The first biasing member 50A is positioned inside the wire W. The second biasing member 50B is positioned outside the wire W. Specifically, the wire W is held within the exterior member 30 by the first biasing member 50A and the second biasing member 50B.

[0069] When the biasing members 50A and 50B are arranged on both sides of the electric wire W, the curvature radius R of the electric wire W is stabilized as described below. Figure 8 FIG. 5 shows the shape of the wire W when one biasing member 50 is arranged outside the wire W. Figure 8 As shown, when the electric wire W is arranged inside the urging member 50 , the electric wire W may be separated from the urging member 50 due to its own weight or the like.

[0070] exist Figure 9 FIG. 5 shows the shape of the wire W when one biasing member 50 is arranged inside the wire W. Figure 9 As shown, when the wire W is arranged outside the urging member 50, the wire W may be separated from the urging member 50 due to tolerance. When the wire W is separated from the urging member 50, the curvature radius R of the wire W is likely to deviate from the target size.

[0071] By placing the wire W between the two urging members 50A, 50B, the curvature radius R of the wire W can be controlled to a target value. In addition, by generating a bending reaction force using the two urging members 50A, 50B, the urging members 50A, 50B can be made thinner.

[0072] As described above, the wiring structure 1 of this embodiment includes a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a force-applying 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 slider 210. The slider 210 moves in the vehicle front-rear direction X relative to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 includes 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 force-applying member 50 are inserted through the exterior member 30.

[0073] The urging member 50 forms curved portions 33 and 34 between the first end portion 30a and the second end portion 30b of the exterior member 30 , which are curved in the vehicle longitudinal direction X. The wiring structure 1 of this embodiment can stabilize the shapes of the curved portions 33 and 34 by the urging member 50 .

[0074] In the curved portions 33 and 34 of the exterior member 30 , the urging member 50 may be located radially inward of the wire W. In this case, the wire W supports the curved portion of the urging member 50 , and an appropriate curvature radius R can be formed on the urging member 50 .

[0075] The wiring structure 1 may also include two biasing members 50A and 50B. In the curved portions 33 and 34 of the exterior member 30, the first biasing member 50A is positioned radially inward relative to the wire W, while the second biasing member 50B is positioned radially outward. With this configuration, the curvature radius R of the wire W is controlled to a target value.

[0076] In the curved portions 33 and 34 of the exterior member 30 , the urging member 50 may be located radially outward from the wires W. In this case, the pressing forces F1 and F2 are transmitted from the urging member 50 to the exterior member 30 without passing through the wires W.

[0077] [Modification of the embodiment]

[0078] Modifications of the embodiment will be described. Figure 10 is a plan view of a biasing member according to a modification of the embodiment. Figure 11 is a cross-sectional view of a biasing member according to a modified example of the embodiment, Figure 12 : is a diagram illustrating the curvature radius R of the urging member. In the modification of the embodiment, the difference from the above embodiment is that, for example, the urging member 50 has a curved cross-sectional shape. Figure 11 Shown in Figure 10 XI-XI section.

[0079] like Figure 10As shown in FIG. 1 , the force applying member 50 is a plate-shaped member having an axial direction Ax. The axial direction Ax is the longitudinal direction of the force applying member 50. The force applying member 50 is, for example, a metal plate. Figure 11 As shown, the cross section 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 section, the size of the curvature radius R is determined by the cross section radius r.

[0080] like Figure 12 As shown, when the force-applying member 50 is bent as a single unit, a curved portion 53 is formed on the force-applying member 50. The radius R0 of the curved portion 53 corresponds to the radius r of the cross section. When the cross section radius r is small, the force-applying member 50 forms a curved portion 53 with a small radius R0. When the cross section radius r is large, the force-applying member 50 forms a curved portion 53 with a large radius R0. In other words, the radius R0 of the curved portion 53 can be controlled by the radius r.

[0081] The cross-sectional radius r is determined, for example, by the distance between the first end portion 30a and the second end portion 30b of the exterior member 30 in the vehicle vertical direction Y. The cross-sectional radius r may also be determined by Figure 2 The second distance L2 at the fully open position shown is determined accordingly. Figure 12 FIG. 5 shows a biasing member 50 that is bent 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 biasing member 50 is Figure 12 When folded back in this manner, the urging member 50 forms a curved shape having 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).

[0082] R0=R2=L2 / 2 (1)

[0083] When the radius r of the cross section is determined as described above, Figure 2 As shown, when the outer cover member 30 is fully opened, a curved portion 34 having a radius R2 is formed. The size of the radius R2 at this time is determined by the radius r of the cross section of the urging member 50 .

[0084] When the sliding body 210 is in the fully closed position, Figure 1As shown, a curved portion 33 is formed in the exterior member 30. The radius R1 of the curved portion 33 is smaller than the size determined by 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 portion 30a and the second end portion 30b is smaller than the second distance L2, the force-applying member 50 forms a curvature radius R corresponding to the distance L. In this way, the force-applying member 50 can set the curvature radius R of the exterior member 30 to the maximum size corresponding to the distance L when the sunroof 200 is fully closed, fully opened, and opened and closed. In addition, the sunroof 200 of the modified example is the same as the sunroof 200 of the above-mentioned embodiment, and moves the sliding body 210 in a manner such that the second distance L2 is larger than the first distance L1.

[0085] The radius r of the cross section can also be, for example, Figure 1 The first distance L1 at the fully closed position shown in FIG. Figure 12 When folded back in this manner, the urging member 50 forms a curved shape having the first distance L1 as a diameter. In other words, the design value of the cross-sectional radius r is determined so as to realize the following formula (2).

[0086] R0=R1=L1 / 2 (2)

[0087] When the radius r of the cross section is determined as described above, Figure 13 As shown, when fully open, the exterior member 30 forms a curved portion 34 having a radius R1. The radius R1 of the curved portion 34 is determined by the radius r of the cross section of the force-applying member 50. When the slider 210 is in the fully open position, the exterior member 30 forms an inclined portion 35. The inclined portion 35 extends from the curved portion 34 to the second fixing portion 20 and is inclined relative to the vehicle longitudinal direction X.

[0088] In addition, when the sliding body 210 is in the fully closed position, as shown in FIG. Figure 1 As shown, a curved portion 33 having a radius R1 is formed in the exterior member 30. The size of the radius R1 of the curved portion 33 is determined by the radius r of the cross section.

[0089] When the cross-sectional radius r is determined so as to realize the formula (2), the wire harness can be shortened to the minimum. In other words, the wires W, the exterior member 30, and the urging member 50 can be shortened to the minimum.

[0090] Furthermore, the actual value of the cross-sectional radius r may not always match the theoretical value required to implement equations (1) and (2). For example, in the force-applying member 50, the cross-sectional radius r may slightly deviate from the theoretical value due to manufacturing tolerances. In this case, the radius of the resulting curved portions 33 and 34 may deviate from the target radii R1 and R2. In other words, the diameters of the curved portions 33 and 34 may sometimes deviate from the first distance L1 and the second distance L2.

[0091] Even if the actual cross-sectional radius r matches the theoretical value, the radius of the formed curved portions 33 and 34 may differ from the target radius R1 and R2. In other words, when the urging member 50 is bent back, the radius of the actually formed curved portions 33 and 34 may deviate from the target value.

[0092] Furthermore, the cross-sectional radius r of the force-applying member 50 may be different at different positions in the axial direction Ax. For example, the force-applying member 50 may include 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 implements equation (2). The cross-sectional radius r of the second portion may be a value that implements equation (1).

[0093] As described above, the slider 210 of this embodiment moves in the vehicle vertical direction Y in addition to the vehicle longitudinal direction X between the fully closed position, which closes the opening 120a, and the fully open position, which opens the opening 120a. In the fully closed position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the first distance L1. In the fully open position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the second distance L2, which is different from the first distance L1.

[0094] The urging member 50 is configured to form a curved portion having a first distance L1 as a diameter, or a curved portion having a second distance L2 as a diameter. The urging member 50 may also be configured to form both the curved portion 33 having the first distance L1 as a diameter and the curved portion 34 having the second distance L2 as a diameter.

[0095] The exemplary force applying member 50 is a plate-shaped member. A cross-section of the force applying member 50 perpendicular to the axial direction Ax of the force applying member 50 is an arc. The radius r of the arc is determined so that when the force applying member 50 is folded back, the force applying member 50 forms a curved shape with a first distance L1 as its diameter, or so that when the force applying member 50 is folded back, the force applying member 50 forms a curved shape with a second distance L2 as its diameter.

[0096] When the radius r is such that the biasing member 50 forms a curved shape with a diameter of the first distance L1, the exterior member 30 and the wire W can be minimized. When the radius r is such that the biasing member 50 forms a curved shape with a diameter of the second distance L2, the curvature radius R of the exterior member 30 can be set to the maximum value corresponding to the distance L.

[0097] Furthermore, the method for forming a curved portion of a predetermined radius in the force-applying member 50 is not limited to the value of the cross-sectional radius r. For example, the force-applying member 50 may include a main body and a limiting portion that limits the shape of the curved portion formed in the main body. As an example, the limiting portion of the force-applying member 50 may also be formed from a superelastic alloy. In this case, the limiting portion that imparts a curved shape of radius R1 may be disposed in the portion of the main body of the force-applying member 50 that forms the curved portion 33. The limiting portion that imparts a curved shape of radius R2 may also be disposed in the portion of the main body of the force-applying member 50 that forms the curved portion 34. The main body of the force-applying member 50 is capable of generating a reaction force in the vehicle vertical direction Y while the curved shape is limited by the limiting portion.

[0098] The contents disclosed in the above-mentioned embodiments and modifications can be implemented in combination as appropriate.
