[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 is disposed on a lower side Y2 of the sliding body 210 and extends in the vehicle front-rear direction X. The rail 220 supports a mechanism that moves the sliding body 210 and guides this mechanism in the vehicle front-rear direction X. The rail 220 further supports the exterior member 30 and forms 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 fixed part 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixed part 10 of the present embodiment is fixed to a rail 220. The first fixed part 10 may be a protector that protects the electric wire W. The first fixed part 10 is molded, for example, from an insulating synthetic resin. The first fixed part 10 has a space in which the electric wire W is 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 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 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] In the sunroof 200 of this embodiment, the second distance L2 in the fully open position is greater than the first distance L1 in 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. Also, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed in the exterior member 30 when the sliding body 210 is in another position. In other words, the radius of the curved shape formed in the exterior member 30 is smallest when the sliding body 210 is in the fully closed position.
[0028] The second end 30b of the exterior member 30 moves together with the slider 210. At this time, the exterior member 30 follows the movement of the second fixing portion 20 while gradually changing the position where the curved shape is formed.
[0029] The biasing member 50 of the present embodiment is a member that presses the exterior member 30 toward the sliding body 210. The biasing member 50 of the present embodiment is a plate-shaped member that is elastically deformable. The biasing member 50 is made of metal or resin.
[0030] 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The urging member 50 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The urging member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the urging member 50 has a width capable of supporting the multiple electric wires W.
[0031] 3 is disposed on the inner side with respect to the electric wire W. Therefore, at the curved portions 33, 34, the urging member 50 is located on the radially inner side with respect to the electric wire W. As shown in FIG. 3, the urging member 50 applies pressing forces F1, F2 to the exterior member 30.
[0032] 4, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a 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.
[0033] The biasing member 50 bent to have the curved portion 54 forms curved portions 33, 34 in the exterior member 30, and applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle 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.
[0034] The pressing force F1 forms a first extension portion 31 in the exterior member 30. The pressing force F2 forms a second extension portion 32 in the exterior member 30. As shown in FIG. 2 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.
[0035] The biasing member 50 of this embodiment is configured to press the exterior member 30 toward the sliding body 210 when the sliding body 210 is in the fully closed position and when the sliding body 210 is in the fully open position. In other words, the biasing member 50 has 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.
[0036] As described below, the wiring structure 1 of this embodiment is configured to suppress the tapered shape of the urging member 50. First, the tapered shape formed on the urging member will be described.
[0037] 5 shows a tapered shape formed on the biasing member 150 of the comparative example. The biasing member 150 of the comparative example has a flat plate shape. The biasing member 150 is formed with a curved portion 151 and a straight portion 152. The straight portion 152 is a portion that extends linearly, and is formed along each of the slide body 210 and the rail 220.
[0038] The curved portion 151 has a tip portion 151a and two end portions 151b. The tip portion 151a is a central portion of the curved portion 151, and has a convex shape facing the vehicle front-rear direction X. The end portions 151b are end portions of the curved portion 151 in the vehicle up-down 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 from the end portions 151b toward the tip portion 151a.
[0039] 5 shows an imaginary circle IC. The imaginary circle IC is a circle whose diameter is the distance L0 from the rail 220 to the 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 end end 151b. When the distance L0 from the rail 220 to the sliding body 210 is small, such a tapered shape is easily formed in the curved portion 151.
[0040] As described below, the urging member 50 of this embodiment has a wavy portion 53. The wavy portion 53 is provided in a portion that forms a curved portion with respect to the exterior member 30. Fig. 6 shows a side view of the urging member 50 as viewed from the width direction of the urging member 50. The wiring structure 1 is disposed such that, for example, the width direction H of the exterior member 30 and the urging member 50 coincides with the vehicle width direction of the vehicle 100.
[0041] In the biasing member 50 of Fig. 6, a wavy portion 53 is provided over the entire range from the first end 50a to the second end 50b. The first end 50a is an end corresponding to the first end 30a of the exterior member 30. The second end 50b is an end corresponding to the second end 30b of the exterior member 30. The wavy portion 53 has a wave shape formed at a predetermined pitch. In the biasing member 50 arranged along the electric wire W, the unevenness of the wavy portion 53 is repeated along the extending direction Ex of the electric wire W.
[0042] The biasing member 50 arranged along the electric wire W has an orthogonal direction Ot perpendicular to the extending direction Ex of the electric wire W. The orthogonal direction Ot is perpendicular to both the longitudinal direction and the width direction of the biasing member 50. The wavy portion 53 has a plurality of first peaks 53a and a plurality of second peaks 53b. In the wavy portion 53, the first peaks 53a and the second peaks 53b are alternately arranged. The first peaks 53a have a convex shape toward a first side S1 perpendicular to the extending direction Ex. The second peaks 53b have a convex shape toward a second side S2 perpendicular to the extending direction Ex.
[0043] The shape of the first peak 53a when viewed in the width direction of the urging member 50 is a tapered shape that narrows toward the tip of the first side S1. The shape of the second peak 53b when viewed in the width direction of the urging member 50 is a tapered shape that narrows toward the tip of the second side S2. The shapes of the first peak 53a and the second peak 53b shown in FIG. 6 are substantially triangular. That is, the illustrated wavy portion 53 has a shape like a triangular wave when viewed in the width direction of the urging member 50. The first peak 53a and the second peak 53b are arranged, for example, at equal pitches.
[0044] 7 shows the wavy portion 53 forming the curved portion 54. When a bending moment M1 acts on the wavy portion 53, the wavy portion 53 deforms to form an arc shape. At this time, the wavy portion 53 deforms to increase the pitch p1 of the first peak portion 53a and decrease the pitch p2 of the second peak portion 53b. This deformation allows the wavy portion 53 to flexibly deform with respect to the moment M1. More specifically, in the wavy portion 53, the distribution of the reaction force with respect to the moment M1 is less likely to vary.
[0045] For example, in the biasing member 150 of the comparative example, one of the causes of the curved portion 151 being tapered is thought to be an increase in the reaction force against the moment M1 at the end portion 151b. In the biasing member 50 of this embodiment, the reaction force at the end portion 54b of the curved portion 54 is suppressed, thereby suppressing the tapered shape at the curved portion 54. Also, in the curved portion 54, a large difference is unlikely to occur between the reaction force at the tip portion 54a against the moment M1 and the reaction force at the end portion 54b against the moment M1. Therefore, the biasing member 50 of this embodiment can suppress the tapered shape at the curved portion 54.
[0046] The pitch of the first peaks 53a and the second peaks 53b in the wavy portion 53 is determined so as to appropriately suppress a tapered shape in the curved portion 54. The wavy portion 53 is formed, for example, so that the curved portion 54 has a plurality of first peaks 53a and a plurality of second peaks 53b.
[0047] In addition, the range in which the wavy portion 53 is provided in the urging member 50 is not limited to the entire range from the first end 50a to the second end 50b. In the urging member 50 shown in Fig. 8, the wavy portion 53 is provided in a portion of the urging member 50. More specifically, the wavy portion 53 is provided in a range 50c that forms the curved portion 33 when fully closed. In the urging member 50 in Fig. 8, the portion other than the range 50c that forms the curved portion 33 has a flat plate shape.
[0048] 9 shows a state in which the biasing member 50 of FIG. 8 forms a curved portion 33 in the exterior member 30. When the sliding body 210 is in the fully closed position, the distance from the sliding body 210 to the rail 220 in the vehicle up-down direction Y is the shortest. At this time, the tapered shape of the curved portion 54 of the biasing member 50 is suppressed, and thus the deterioration of the bending durability of the electric wire W is suppressed.
[0049] The urging member 50 may have a plurality of wavy portions 53. Fig. 10 shows the urging member 50 having a plurality of wavy portions 53. The urging member 50 of Fig. 10 has a main plate member 50M and an additional plate member 50X. The main plate member 50M is provided with wavy portions 53 over the entire area, similar to the urging member 50 of Fig. 6. The main plate member 50M has a range 50d that forms the curved portion 34 when fully open.
[0050] The additional plate-shaped member 50X has a wavy portion 53. The wavy portion 53 of the additional plate-shaped member 50X has a plurality of first peaks 53a and a plurality of second peaks 53b. The first peaks 53a and the second peaks 53b are alternately arranged. The additional plate-shaped member 50X is overlapped on a part of the main plate-shaped member 50M. The additional plate-shaped member 50X is overlapped, for example, in the range 50d that forms the curved portion 34. That is, the urging member 50 in FIG. 10 forms the curved portion 34 by the two wavy portions 53.
[0051] Fig. 11 shows a state in which the urging member 50 of Fig. 10 forms the curved portion 34. When the sliding body 210 is in the fully open position, the distance from the sliding body 210 to the rail 220 is greater than when the sliding body 210 is in the fully closed position. Since the curved portion 54 at this time is formed by two wavy portions 53, a sufficient pressing force F2 is ensured.
[0052] The shape of the first peak 53a and the second peak 53b in the wavy portion 53 is not limited to the shape illustrated in Fig. 6. The peaks 53a and 53b may be triangular shapes with rounded apexes in Fig. 6. The wavy portion 53 may have curved peaks 53a and 53b as illustrated in Fig. 12. The peaks 53a and 53b have curved shapes with rounded apexes of triangular waves. The shape of the wavy portion 53 when viewed in the width direction of the urging member 50 may be a sine wave shape.
[0053] As described above, the wiring structure 1 of the present embodiment includes the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, and the plate-shaped 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 longitudinal 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. The biasing member 50 forms a curved portion curved toward the vehicle longitudinal direction X between the first end portion 30a and the second end portion 30b of the exterior member 30.
[0054] The urging member 50 has a wavy portion 53 provided in a portion forming a curved portion. The wavy portion 53 has a plurality of first peaks 53a and a plurality of second peaks 53b. The first peaks 53a and the second peaks 53b are alternately arranged along the extending direction Ex of the electric wire W. When viewed from the width direction of the urging member 50, the shape of the first peaks 53a is a convex shape toward the first side S1 perpendicular to the extending direction Ex. When viewed from the width direction of the urging member 50, the shape of the second peaks 53b is a convex shape toward the second side S2 opposite to the first side S1. According to the wiring structure 1 of this embodiment, the flexible wavy portion 53 forms a curved portion in the exterior member 30, thereby suppressing the tapered shape of the urging member 50.
[0055] The shape of the first peak 53a when viewed in the width direction of the urging member 50 is a tapered shape that narrows toward the tip of the first side S1. The shape of the second peak 53b when viewed in the width direction of the urging member 50 is a tapered shape that narrows toward the tip of the second side S2. The wavy portion 53 having such a shape can be easily deformed to change the pitch p1 and the pitch p2.
[0056] The exterior member 30 is not limited to a so-called corrugated tube, and may be a braided tube or other member used as an exterior member.
[0057] The urging member 50 may be disposed on the outer side with respect to the electric wire W. That is, the urging member 50 may be disposed on the outer side of the electric wire W in the curved portions 33 and 34 in the radial direction.
[0058] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
