[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-151906 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors of the present application have considered disposing a rigid biasing member inside an exterior member in a wiring structure between a vehicle body and a slide body. Here, from the viewpoint of ensuring the durability of the biasing member against bending, it is preferable to reduce the rigidity of the biasing member. On the other hand, when a curved portion is formed in the exterior member and the biasing member, if the rigidity of the biasing member is low, the curved portion is likely to have a tapered shape. A tapered shape of the curved portion leads to a reduction in the bending radius of the electric wire.

[0005] An object of the present invention is to provide a wiring structure that can prevent the biasing member from tapering. [Means for solving the problem]

[0006] The wiring structure of the present invention includes an exterior member having a first fixed portion fixed to the body of a vehicle, a second fixed portion fixed to a sliding body that moves in the longitudinal direction of the vehicle relative to an opening provided in the 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 rod-shaped or plate-shaped biasing member that is inserted into the exterior member and forms a curved portion that curves in the longitudinal direction of the vehicle between the first end and the second end of the exterior member, wherein the biasing member has an arc portion that forms the curved portion when the sliding body is positioned at an end of a sliding range, and the arc portion is formed to have an arc shape of a predetermined radius when no external force is acting on the biasing member, and the predetermined radius is greater than half the distance in the vertical direction of the vehicle from the first end to the second end when the sliding body is positioned at the end of the sliding range. [Effects of the Invention]

[0007] The biasing member of the wiring structure according to the present invention has an arc portion that forms the curved portion when the slider is positioned at the end of the sliding range. The arc portion is formed to have an arc shape with a predetermined radius when no external force is acting on the biasing member. The wiring structure according to the present invention has the effect of suppressing the tapered shape of the biasing member. [Brief explanation of the drawings]

[0009] Hereinafter, a wiring structure according to an embodiment of the present invention will be described in detail with reference to the drawings. 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.

[0010] [Embodiment] An embodiment will be described with reference to FIGS. 1 to 10. This embodiment relates to a wiring structure.

FIG. 3 shows a cross section taken along line III-III in 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 extends in the vehicle longitudinal direction X. The rail 220 supports a mechanism that moves the slider 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 in 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 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 biasing member 50 when the sliding body 210 is in another position. In other words, the magnitude of the radius of the curved shape formed in the biasing member 50 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 rod-shaped or plate-shaped member that is elastically deformable. The biasing member 50 is made of, for example, metal or resin.

[0030] As shown in Fig. 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The cross-sectional shape of the illustrated biasing member 50 is rectangular. In other words, the illustrated biasing member 50 is a plate-shaped member. The biasing member 50 in Fig. 3 is disposed on the outer side with respect to the electric wire W. Therefore, at the curved portions 33 and 34, the biasing member 50 is located on the radially outer side with respect to the electric wire W. As shown in Fig. 3, the biasing member 50 applies pressing forces F1 and F2 to the exterior member 30.

[0031] 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.

[0032] 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.

[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 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.

[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 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.

[0035] As will be described below, the wiring structure 1 of this embodiment can suppress the tapered shape of the urging member 50 at the curved portions 33 and 34. FIG. 5 shows the tapered shape formed in the urging member 150 of the comparative example. The urging member 150 of the comparative example is a rod-shaped or flat plate-shaped member. The urging member 150 is disposed between the slider 210 and the rail 220 by bending a linear member. By being sandwiched between the slider 210 and the rail 220, the urging 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.

[0036] 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.

[0037] 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 sliding body 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 terminal end 151b. When the linear biasing member 150 is folded back 180 degrees, a deviation in the bending radius occurs in the curved portion 151, which is greatly deformed, and this type of tapered shape is likely to occur.

[0038] As shown in Fig. 6, the urging member 50 of this embodiment has an arc portion 53. The arc portion 53 is a portion that forms the curved portions 33, 34 in the exterior member 30. The exemplified urging member 50 has a first arc portion 53A and a second arc portion 53B as the arc portion 53. The first arc portion 53A is a portion that forms the curved portion 33 when the sliding body 210 is in the fully closed position. The second arc portion 53B is a portion that forms the curved portion 34 when the sliding body 210 is in the fully open position.

[0039] The biasing member 50 has a first end 50a and a second end 50b. The first end 50a is an end corresponding to the first end 30a of the exterior member 30 and is inserted into the first fixing portion 10. The second end 50b is an end corresponding to the second end 30b of the exterior member 30 and is inserted into the second fixing portion 20. The first arc portion 53A is disposed on the second end 50b side relative to the second arc portion 53B.

[0040] The arc portion 53 is formed to have an arc shape with a predetermined radius when no external force is acting on the urging member 50. The state when no external force is acting on the urging member 50 refers to, for example, a state when no bending moment is acting on the urging member 50.

[0041] When the urging member 50 is made of metal, the arc portion 53 is formed by, for example, bending a metal rod or a metal plate. When the urging member 50 is made of resin, the arc portion 53 is formed by, for example, injection molding.

[0042] The biasing member 50 is formed, for example, linearly, except for the arc portion 53. The first arc portion 53A is formed to have an arc shape with a radius R11 when not subjected to an external force. The second arc portion 53B is formed to have an arc shape with a radius R12 when not subjected to an external force.

[0043] The radius R11 of the first arc-shaped portion 53A is greater than the radius R1 of the curved portion 33, and the radius R12 of the second arc-shaped portion 53B is greater than the radius R2 of the curved portion 34. In other words, the radius R11 of the first arc-shaped portion 53A is greater than half the first distance L1, and the radius R12 of the second arc-shaped portion 53B is greater than half the second distance L2.

[0044] As will be described below, the arc portion 53 is deformed so as to reduce the bending radius when forming the curved portions 33 and 34. For example, the bending radius of the first arc portion 53A is reduced when forming the curved portion 33, as will be described below.

[0045] 7 shows the biasing member 50 when the slider 210 is in the half-open position. Note that FIG. 7 is a diagram for explaining the shape of the biasing member 50, and the exterior member 30 is omitted. The slider 210 is moving toward the front side X1 in the vehicle longitudinal direction X toward the fully closed position, as indicated by the arrow AR3. The biasing member 50 shown in FIG. 7 has a first arc portion 53A protruding toward the front side X1 in the vehicle longitudinal direction X.

[0046] The biasing member 50 is pressed in the vehicle up-down direction Y by the slide body 210 and the rail 220. In other words, a bending moment is applied to the biasing member 50 due to forces received from the slide body 210 and the rail 220. The radius R13 of the first arc-shaped portion 53A at this time is smaller than the radius R11 when no external force is applied and is larger than the radius R1 of the curved portion 33 when fully closed. The biasing member 50 is formed with curved portions 55 and 56 adjacent to the first arc-shaped portion 53A. The curved portion 55 is formed between one end of the first arc-shaped portion 53A and a straight portion 57 along the rail 220. The curved portion 56 is formed between the other end of the first arc-shaped portion 53A and a straight portion 58 along the slide body 210.

[0047] FIG. 8 shows the biasing member 50 when the slider 210 reaches the fully closed position. The distance between the slider 210 and the rail 220 is smaller than the distance in the state shown in FIG. 7. The bending radius of the first arc portion 53A at this time is equal to the radius R1 of the curved portion 33 when fully closed. The biasing member 50 forms the curved portion 33 in the exterior member 30 by means of the first arc portion 53A. The bending radius R1 of the first arc portion 53A is smaller than the radius R11 in an unloaded state where no bending moment is applied. Therefore, the biasing member 50 can apply pressing forces F1 and F2 to the exterior member 30.

[0048] In the wiring structure 1 of this embodiment, the first arc portion 53A forming the curved portion 33 is preliminarily formed into an arc shape. The amount of deformation of the first arc portion 53A when it deforms into a curved shape with a radius R1 is smaller than the amount of deformation of a straight member when it deforms into a curved shape with a radius R1. In other words, the stress of the first arc portion 53A when it has a curved shape with a radius R1 is smaller than the stress when a straight member deforms into a curved shape with a radius R1. By suppressing the amount of deformation of the first arc portion 53A from an unloaded state where no bending moment is applied, the first arc portion 53A is less likely to become tapered. Furthermore, by suppressing the stress generated in the first arc portion 53A when the curved portion 33 is formed, the first arc portion 53A is less likely to become tapered.

[0049] The arc length AL1 of the first arc portion 53A shown in FIG. 6 is determined, for example, based on the radius R1 of the curved portion 33 when fully closed. The circumferential length of the circle having the radius R1 is defined as C1. In this case, the magnitude of the arc length AL1 is determined, for example, to satisfy equation (1). In other words, the arc length AL1 is set to be equal to or greater than the length of a semicircle of the circle having the radius R1. This makes it difficult for stress concentration to occur in the portion of the biasing member 50 that forms the curved portion 33, thereby suppressing a tapered shape. AL1≧C1 / 2 (1)

[0050] In the wiring structure 1 of this embodiment, the second arc portion 53B that forms the curved portion 34 is pre-formed in an arc shape. The amount of deformation when the second arc portion 53B deforms into a curved shape with radius R2 is smaller than the amount of deformation when a straight member deforms into a curved shape with radius R2. By suppressing the amount of deformation of the second arc portion 53B from an unloaded state where no bending moment is applied, the second arc portion 53B is less likely to become tapered. Furthermore, by suppressing the stress generated in the second arc portion 53B when forming the curved portion 34, the second arc portion 53B is less likely to become tapered.

[0051] The arc length AL2 of the second arc portion 53B shown in FIG. 6 is determined, for example, based on the radius R2 of the curved portion 34 when fully open. The circumferential length of the circle having the radius R2 is defined as C2. In this case, the arc length AL2 is determined, for example, to satisfy equation (2). In other words, the arc length AL2 is set to be equal to or greater than the length of a semicircle of the circle having the radius R2. This makes it difficult for stress concentration to occur in the portion of the biasing member 50 that forms the curved portion 34, thereby suppressing a tapered shape. AL2≧C2 / 2 (2)

[0052] As described above, the wiring structure 1 of this embodiment has the first fixed portion 10, the second fixed portion 20, the exterior member 30, the electric wire W, and the rod-shaped or 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 fore-and-aft direction X relative 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 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 into the exterior member 30.

[0053] The biasing member 50 forms curved portions 33, 34 that curve in the vehicle longitudinal direction X between the first end 30a and the second end 30b of the exterior member 30. The biasing member 50 has an arc portion 53. The arc portion 53 is a portion that forms the curved portions 33, 34 when the sliding body 210 is positioned at the end of the sliding range. In this embodiment, the fully closed position and the fully open position of the sliding body 210 are the end of the sliding range.

[0054] The arc portion 53 is formed to have an arc shape with predetermined radii R11, R12 when no external force is acting on the biasing member 50. The predetermined radii R11, R12 are greater than half the distances L1, L2 along the vehicle up-down direction Y from the first end 30a to the second end 30b when the sliding body 210 is located at the end of the sliding range. For example, the radius R11 of the first arc portion 53A is greater than half the first distance L1 when the sliding body 210 is in the fully closed position. In the wiring structure 1 of this embodiment, the arc portion 53 is formed in an arc shape in advance, thereby suppressing the tapering of the biasing member 50 at the curved portions 33, 34.

[0055] In the sliding range of the slider 210 of this embodiment, one end is a fully closed position and the other end is a fully open position. The fully closed position is a position where the slider 210 closes the opening 120a, and the fully open position is a position where the slider 210 opens the opening 120a. The biasing member 50 has, as the arc portion 53, a first arc portion 53A and a second arc portion 53B.

[0056] The first arcuate portion 53A forms the curved portion 33 when the sliding body 210 is in the fully closed position. The second arcuate portion 53B forms the curved portion 34 when the sliding body 210 is in the fully open position. The wiring structure 1 of this embodiment can prevent the biasing member 50 from tapering when the sliding body 210 is in the fully closed position and when the sliding body 210 is in the fully open position.

[0057] The shape of the arc portion 53 in the no-load state is not limited to the shape shown in Fig. 6. For example, as shown in Fig. 9, the central angle of the arc portion 53 may be smaller than 180 degrees. The central angle of the arc portion 53 may be, for example, 90 degrees, 120 degrees, 150 degrees, or another angle.

[0058] In the urging member 50, the shape of the arc portion 53 may include portions with different bending radii. For example, in the first arc portion 53A, the bending radius of the central portion 53c of the first arc portion 53A may be larger than the bending radius of both end portions 53e of the first arc portion 53A. In this case, the central portion 53c has a relatively flat shape compared to both end portions 53e.

[0059] 10, in arc portion 53, connecting portion 53j with the linear portion may be curved. The direction of curvature of connecting portion 53j is opposite to the direction of curvature of arc portion 53. That is, in arc portion 53 shown in FIG. 10, connecting portion 53j is curved so as to form an inflection point.

[0060] The urging member 50 may be a rod-shaped member having a circular cross-sectional shape. The urging member 50 may be a rod-shaped member having a polygonal cross-sectional shape. The exterior member 30 is not limited to a so-called corrugated tube. The exterior member 30 may be a braided tube or other member used as an exterior member. The urging member 50 may be arranged inside the electric wire W. That is, the urging member 50 may be arranged radially inside the electric wire W at the curved portions 33, 34.
