[0003] [Patent Document 1] JP 2010-195189 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the electric wire is inserted into the exterior member and one end of the exterior member moves together with the sliding body, it is preferable that the exterior member can deform appropriately. For example, when the sliding body moves not only in the sliding direction but also in a direction intersecting the sliding direction, the radius of the curved portion formed in the exterior member changes. If the exterior member cannot deform appropriately in response to the change in the radius of the curved portion, there is a possibility that the exterior member will hinder the movement of the sliding body.

[0005] An object of the present invention is to provide a wiring structure capable of smoothly moving a slider. [Means for solving the problem]

[0006] The wiring structure of the present invention includes an exterior member having a first fixed portion fixed to a vehicle body, a second fixed portion fixed to a sliding body that moves along the vehicle fore-and-aft direction relative to an opening provided in a roof of the vehicle body, a first end portion held by the first fixed portion and a second end portion held by the second fixed portion, an electric wire inserted into the exterior member, and a biasing member that is inserted into the exterior member and forms a curved portion that curves toward the vehicle fore-and-aft direction between the first end portion and the second end portion of the exterior member, wherein the sliding body moves in the vehicle up-and-down direction in addition to the vehicle fore-and-aft direction between a fully closed position that closes the opening and a fully open position that opens the opening, and the exterior member is configured to deform while following a change in the radius of the curved portion due to the movement of the sliding body in the vehicle up-and-down direction. Effect of the Invention

[0007] The wiring structure according to the present invention includes an exterior member and a biasing member that is inserted into the exterior member and forms a curved portion that curves in the vehicle front-rear direction between a first end and a second end of the exterior member. The exterior member is configured to deform while following a change in the radius of the curved portion caused by the movement of the slider in the vehicle up-down direction.

[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 can be elastically deformed. The exterior member 30 is, for example, a braided tube. The braided tube is formed by weaving fibers into a mesh shape. The fibers that make up the braided tube are preferably elastic. As described later, the exterior member 30 is elastic and configured to deform while following the change in radius of the curved portion.

[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, the cross-sectional shape of the biasing member 50 of this embodiment is rectangular. The illustrated biasing member 50 has a flat plate shape, for example, a metal plate or a resin plate. The exterior member 30 can be deformed into a shape corresponding to the shape of the biasing member 50. The cross-sectional shape of the exterior member 30 in a state in which the biasing member 50 and the electric wires W are housed therein is, for example, rectangular. The biasing member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the biasing 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. As shown in FIG. 1, the first extension portion 31 is a portion extending along the rail 220. 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 extending 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] Here, the sunroof 200 of this embodiment is configured to move the sliding body 210 in the vehicle up-down direction Y when opening or closing. As the sliding body 210 moves in the vehicle up-down direction Y, the value of the radius R2 of the curved portion 34 in the fully open position differs from the value of the radius R1 of the curved portion 33 in the fully closed position. When the radii of the curved portions 33, 34 change in this manner, it is preferable that the exterior member 30 can flexibly follow the change in radius.

[0036] For example, when the slider 210 moves from the fully open position to the fully closed position, the radius of the curved portion decreases from radius R2 in Fig. 2 to radius R1 in Fig. 1. In this case, the inner peripheral side portion of the curved portion is compressed in the circumferential direction.

[0037] Since a braided tube is used as the exterior member 30, the inner peripheral portion of the curved portion can deform in response to the compression in the circumferential direction. FIG. 5 shows the inner peripheral surface of the curved portion 33 of the exterior member 30. In other words, FIG. 5 is a view of the curved portion 33 in FIG. 1 as seen from the rear side X2. When the radius of the curved portion decreases, the inner peripheral surface of the exterior member 30 is deformed so as to be compressed in the circumferential direction and expanded in the width direction. As shown by the arrow AR2, each mesh of the exterior member 30 shrinks in the circumferential direction. Also, as shown by the arrow AR3, each mesh of the exterior member 30 expands in the width direction.

[0038] When the radius of the curved portion decreases, the outer peripheral surface of the curved portion 33 deforms so as to expand in the circumferential direction and contract in the width direction. That is, the exterior member 30 can offset the expansion in the width direction of the inner peripheral surface by the contraction in the width direction of the outer peripheral surface. Therefore, the exterior member 30 can follow the decrease in the radius of the curved portion.

[0039] As a comparative example, in the case of an exterior member that cannot deform in response to the reduction in radius, wrinkles may be formed in the exterior member. The wrinkles formed in the exterior member generate resistance to the movement of the slide body 210. As a result, the motor becomes larger and the biasing member 50 becomes larger. In contrast, the exterior member 30 of this embodiment can flexibly deform in response to the reduction in radius. Therefore, the exterior member 30 of this embodiment can realize the miniaturization of the sunroof 200.

[0040] When the radius of the curved portion increases, the exterior member 30 undergoes deformation opposite to that when the radius decreases. In the exterior member 30, the inner peripheral surface of the curved portion expands in the circumferential direction, and the outer peripheral surface contracts in the circumferential direction. Therefore, the exterior member 30 can follow the increase in the radius of the curved portion by deforming the inner peripheral surface and the outer peripheral surface in the opposite directions. In this way, the exterior member 30 of this embodiment is configured to deform while following the change in the radius of the curved portion due to the movement of the sliding body 210.

[0041] The exterior member 30 may be a flexible tube such as a corrugated tube. FIG. 6 shows a corrugated tube as the exterior member 30. The exterior member 30 is a cylindrical member and is flexible. The exterior member 30 has a slit 35. The slit 35 is provided over the entire length of the exterior member 30 from the first end 30a to the second end 30b. In other words, the exterior member 30 has a C-shaped cross section.

[0042] 6 has a first edge 36 and a second edge 37 that face each other with a slit 35 therebetween. The first edge 36 and the second edge 37 are end portions along the slit 35 and extend in the axial direction of the exterior member 30. The first edge 36 is located radially inward of the second edge 37 at the curved portions 33 and 34.

[0043] The exterior member 30 has a first semi-cylindrical portion 38 including a first edge portion 36, and a second semi-cylindrical portion 39 including a second edge portion 37. The semi-cylindrical portions 38, 39 have a semicircular cross-sectional shape. The first semi-cylindrical portion 38 is located on the inner periphery side of the curved portions 33, 34. The second semi-cylindrical portion 39 is a portion located on the outer periphery side of the curved portions 33, 34, and contacts the slide body 210 and the rail 220. The exterior member 30 in FIG. 6 has the slits 35, and thus can deform while following the change in radius of the curved portion.

[0044] 6 is disposed with the slits 35 facing the vehicle width direction WD. In this case, in a cross section perpendicular to the vehicle front-rear direction X, the slits 35 face a direction perpendicular to the vehicle up-down direction Y. As described below, the exterior member 30 can follow the change in radius of the curved portion by deforming so as to shift the first edge portion 36 relative to the second edge portion 37.

[0045] Fig. 7 shows a cross section of the first end 30a when the sliding body 210 is in the fully open position. In this case, as shown in Fig. 2, a curved portion 34 having a relatively large diameter is formed in the exterior member 30. As shown in Fig. 7, at the first end 30a, an end face 36a of the first edge portion 36 and an end face 37a of the second edge portion 37 are at the same position in the vehicle front-rear direction X.

[0046] FIG. 8 shows a cross section of the first end 30a when the sliding body 210 is in the fully closed position. In this case, as shown in FIG. 1, the exterior member 30 is formed with a curved portion 33 having a relatively small diameter. As shown in FIG. 8, the exterior member 30 is deformed so as to shift the first edge portion 36 relative to the second edge portion 37 along the extending direction of the slit 35. More specifically, the exterior member 30 is deformed so as to shift the first edge portion 36 relatively to the second edge portion 37 toward the rear side X2. In the exterior member 30 after the deformation, the end face 36a of the first edge portion 36 is shifted toward the rear side X2 relative to the end face 37a of the second edge portion 37. Due to such deformation, the exterior member 30 follows the reduction in the radius of the curved portion while mitigating the degree of compression on the inner peripheral side of the curved portion 33.

[0047] When the sliding body 210 moves from the fully closed position to the fully open position, the exterior member 30 deforms so as to shift the first edge 36 toward the front side X1 relative to the second edge 37. Due to such deformation, the exterior member 30 follows the increase in the radius of the curved portion. In this manner, the corrugated tube as the exterior member 30 is configured to deform while following the change in the radius of the curved portion caused by the movement of the sliding body 210.

[0048] As will be described with reference to Fig. 9, the second fixing portion 20 allows deformation of the exterior member 30 such that the first edge portion 36 is shifted relative to the second edge portion 37. As shown in Fig. 9, the second fixing portion 20 has a holding structure 21 that holds the second end portion 30b of the exterior member 30. The holding structure 21 has a first holding portion 22 and a second holding portion 23. The first holding portion 22 holds the first semi-cylindrical portion 38 of the exterior member 30.

[0049] The second holding portion 23 holds the second semi-cylindrical portion 39 of the exterior member 30. The second holding portion 23 has a protrusion 23a. The protrusion 23a engages with a groove portion of the corrugated tube serving as the exterior member 30 to lock the second semi-cylindrical portion 39. The second holding portion 23 restricts movement of the second semi-cylindrical portion 39 in the vehicle front-rear direction X.

[0050] The first retaining portion 22 allows the first semi-cylindrical portion 38 to move in the vehicle fore-and-aft direction X. The retaining surface of the first retaining portion 22 allows the first semi-cylindrical portion 38 to slide along the vehicle fore-and-aft direction X. The retaining surface of the first retaining portion 22 is, for example, a smooth surface without any irregularities. Therefore, the second fixing portion 20 allows the exterior member 30 to deform as shown in FIG. 8.

[0051] The retaining structure 21 may be configured to restrict the movement of the first semi-cylindrical portion 38 and to allow the second semi-cylindrical portion 39 to slide in the vehicle front-rear direction X. Even with this configuration, it is possible to allow the deformation of the exterior member 30 as shown in FIG.

[0052] In the present embodiment, the exterior member 30 can also deform at the first end 30a in the same manner as the second end 30b. When the radius of the curved portion changes, the exterior member 30 deforms so as to shift the first edge 36 relative to the second edge 37 at the first end 30a. The first fixing portion 10 holds the first end 30a so as to allow such deformation of the exterior member 30.

[0053] The orientation of the slits 35 is not limited to the vehicle width direction WD shown in Fig. 6. Fig. 10 shows an example of the arrangement of the exterior member 30. The exterior member 30 in Fig. 10 is arranged so that the slits 35 face the vehicle up-down direction Z. More specifically, the exterior member 30 is arranged so that the slits 35 face radially outward at the curved portion. In this case, the slits 35 face the slide body 210 and the rail 220.

[0054] The exterior member 30 thus arranged can deform while following the change in radius of the curved portion caused by the movement of the sliding body 210. FIG. 11 shows the shape of the second end 30b when the sliding body 210 is in the fully closed position. The exterior member 30 is deformed so as to incline the end face 30c of the second end 30b. The end face 30c is inclined toward the rear side X2 as it moves away from the sliding body 210 along the vehicle up-down direction Y. By such deformation, the exterior member 30 follows the decrease in radius of the curved portion while mitigating the degree of compression on the inner peripheral side of the curved portion 33. The exterior member 30 having the slit 35 has a high degree of freedom of deformation compared to the case without the slit 35. Therefore, the exterior member 30 can follow the change in radius of the curved portion by deforming so as to change the degree of inclination of the end face 30c.

[0055] 10, the first end 30a can be deformed in the same manner as the second end 30b. That is, the exterior member 30 can be deformed so that the end face of the second end 30b is inclined in the same manner as the end face of the first end 30a. The end face of the first end 30a is inclined toward the rear side X2 as it moves away from the rail 220 along the vehicle up-down direction Y.

[0056] The arrangement of the urging member 50 inside the exterior member 30 is not limited to the arrangements shown in Fig. 3, Fig. 6, and Fig. 10. For example, the urging member 50 may be arranged so as to be located radially inward of the electric wire W in the curved portions 33 and 34.

[0057] 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 slides 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.

[0058] The biasing member 50 forms curved portions 33, 34 that curve toward the vehicle longitudinal direction X between the first end 30a and the second end 30b of the exterior member 30. The sliding body 210 moves in the vehicle vertical direction Y in addition to the vehicle longitudinal direction X between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. The exterior member 30 is configured to deform while following a change in the radius of the curved portion due to the movement of the sliding body 210 in the vehicle vertical direction Y. In the wiring structure 1 of this embodiment, the exterior member 30 deforms while following a change in the radius of the curved portion, thereby allowing the sliding body 210 to move smoothly.

[0059] The exterior member 30 is, for example, a braided tube that expands and contracts in response to changes in the radius of the curved portion. The braided tube can expand and contract in the circumferential and width directions of the curved portion to accommodate changes in the radius.

[0060] The exterior member 30 is, for example, a flexible tube having a slit 35 extending over the entire length from the first end 30a to the second end 30b. A tube having a slit 35 extending over the entire length has a high degree of freedom in deformation and can deform in accordance with changes in the radius of the curved portion.

[0061] The flexible tube can have a first edge 36 and a second edge 37 that face each other across the slit 35. The flexible tube can follow the change in radius of the curved portion by deforming so as to shift the first edge 36 relative to the second edge 37 along the extension direction of the slit 35.

[0062] The flexible tube is disposed, for example, with the slits 35 facing the vehicle width direction WD. Such an arrangement is suitable for deformation such that the first edge portion 36 is shifted relative to the second edge portion 37.

[0063] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
