[0003] [Patent Document 1] JP 2011-151906 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the wiring structure between the vehicle body and the slide body has an exterior member, the inventors of the present application have considered disposing a biasing member having rigidity inside the exterior member. Here, from the viewpoint of ensuring durability against bending in the biasing member, 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, a tapered shape is likely to occur in the curved portion. If the curved portion has a tapered shape, this leads to a decrease in the bending radius of the electric wire.

[0005] An object of the present invention is to provide a wiring structure that can suppress the tapered shape of a biasing member. [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 body of a vehicle, a second fixed portion fixed to a sliding body that moves along the fore-and-aft direction of the vehicle 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 between the first end portion and the second end portion of the exterior member that curves toward the fore-and-aft direction of the vehicle, and is characterized in that the biasing member has a rod-shaped first member and a plate-shaped second member that supports the electric wire and the first member. Effect of the Invention

[0007] The biasing member of the wiring structure according to the present invention has a rod-shaped first member and a plate-shaped second member that supports the electric wire and the first member. The rod-shaped first member has higher durability against bending for the same bending rigidity compared to a plate-shaped member. In other words, the rod-shaped first member can have high bending rigidity while ensuring durability. The wiring structure according to the present invention has the effect of suppressing the tapered shape of the biasing member. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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. In addition, the components in the following embodiment include those that a person skilled in the art can easily imagine or that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 6. This embodiment relates to a wiring structure. Fig. 1 and Fig. 2 are side views of the wiring structure according to the embodiment, Fig. 3 is a cross-sectional view of the wiring structure according to the embodiment, Fig. 4 is a side view of the wiring structure according to the embodiment, Fig. 5 is a diagram for explaining the tapered shape, and Fig. 6 is a side view of the wiring structure according to the embodiment. Fig. 3 shows a cross section taken along line III-III in Fig. 4.

[0011] As shown in Fig. 1, a wiring structure 1 of the embodiment is applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, an automobile equipped with a power source such as a motor or an engine. The vehicle 100 has a vehicle body 110. The vehicle body 110 has a roof 120 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.

[0012] The vehicle 100 has a sunroof 200 that opens and closes the opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a member that slides along the vehicle front-rear direction X with respect to the opening 120a. The sliding body 210 of this embodiment is a plate-like member that closes or opens the opening 120a. The sliding body 210 may be glass that is configured to be able to transmit light.

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

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

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

[0016] Conversely, when the slide body 210 moves from the fully open position to the fully closed position, the slide body 210 moves toward the front side X1 in the vehicle longitudinal direction X and moves toward the lower side Y2 in the vehicle vertical direction Y.

[0017] 1 to 3, the wiring structure 1 has a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a biasing member 50. The exterior member 30 and the electric wire W configure a wire harness that is wired between the vehicle body 110 and the slide body 210.

[0018] The first fixing part 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixing part 10 may be a protector that protects the electric wires W. The first fixing part 10 is molded, for example, from an insulating synthetic resin. The first fixing part 10 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0019] The second fixing part 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may be a protector that protects the electric wires W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 20 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0020] The exterior member 30 is a cylindrical member that is elastically deformable. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded, for example, from an insulating synthetic resin. The exterior member 30 may have a bellows shape.

[0021] The exterior member 30 has a first end 30a held by the first fixing part 10 and a second end 30b held by the second fixing part 20. The first fixing part 10 holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 along the rail 220 in the vehicle front-rear direction X. The first fixing part 10 of the present embodiment holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 along the slide body 210 in the vehicle front-rear direction X. The second fixing portion 20 of the present embodiment holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.

[0023] An electric wire W and a biasing member 50 are inserted into the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit body. The electric wire W drawn out from the first end portion 30a is connected to a power source or a control device arranged in the vehicle body 110. The electric wire W drawn out from the second end portion 30b is connected to a load arranged on the side of the sliding body 210. The load arranged on the sliding body 210 may be, for example, a lighting device, a light control film arranged on the glass of the sliding body 210, or other electric load.

[0024] As shown in Figs. 1 and 2, the exterior member 30 has curved portions 33, 34 that are curved in the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b. The curved 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 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 minimum 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 slide body 210. As shown in Fig. 1 and Fig. 2, the biasing member 50 forms curved portions 33, 34 that are curved toward the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b of the exterior member 30.

[0030] 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The biasing member 50 has a rod-shaped first member 51 and a plate-shaped second member 52. The first member 51 and the second member 52 are elastically deformable members and are formed of, for example, metal or resin.

[0031] The first member 51 is a rod-shaped member and extends along the electric wire W. The first member 51 is disposed over the entire length of the exterior member 30, for example, from the first end 30a to the second end 30b. The illustrated first member 51 is a round bar having a circular cross-sectional shape.

[0032] The second member 52 is a plate-like member and supports the electric wires W and the first member 51. The second member 52 is disposed over the entire length of the exterior member 30, for example, from the first end 30a to the second end 30b. The illustrated shape of the second member 52 is a flat plate shape with a rectangular cross section. The second member 52 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The second member 52 faces each of the multiple electric wires W and the first member 51 in the vehicle up-down direction Y. In other words, the second member 52 has a width capable of supporting the first member 51 and the multiple electric wires W.

[0033] 3 is disposed on the inner side with respect to the first member 51 and the electric wire W. Therefore, in the curved portions 33 and 34, the second member 52 is located on the inner side with respect to the first member 51 and the electric wire W in the radial direction.

[0034] 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.

[0035] 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.

[0036] The pressing forces F1 and F2 include the restoring force of the first member 51 and the restoring force of the second member 52. That is, in the wiring structure 1 of the present embodiment, the exterior member 30 is pressed toward the sliding body 210 and the rail 220 by the combined force of the restoring forces of the two members 51 and 52.

[0037] 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.

[0038] 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.

[0039] As described below, the wiring structure 1 of this embodiment can suppress the tapered shape of the urging member 50 at the curved portion. The tapered shape will be described with reference to FIG. 5. FIG. 5 shows a tapered shape formed in the urging member 150 of the comparative example. The urging member 150 of the comparative example has a plate shape similar to the second member 52. The urging member 150 of the comparative example does not include a rod-shaped member such as the first member 51. 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 slide body 210 and the rail 220.

[0040] 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.

[0041] 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 slide 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 rigidity of the biasing member 150 is low, such a tapered shape is easily formed in the curved portion 151.

[0042] As a means for suppressing the occurrence of the tapered shape, it is conceivable to increase the thickness of the plate-shaped urging member 150 to increase the rigidity of the urging member 150. On the other hand, increasing the thickness of the urging member 150 may lead to a decrease in durability of the urging member 150 against bending.

[0043] In the wiring structure 1 of this embodiment, the urging member 50 includes a rod-shaped first member 51. When the rod-shaped member and the plate-shaped member have similar bending rigidity, the rod-shaped member has higher durability against bending than the plate-shaped member. In other words, the rod-shaped member can have higher rigidity while ensuring the same durability against bending compared to the plate-shaped member. Therefore, the wiring structure 1 of this embodiment can suppress the tapered shape of the urging member 50 at the curved portion.

[0044] Moreover, the wiring structure 1 of the present embodiment has a plate-shaped second member 52 that supports the electric wire W and the first member 51. The second member 52 can suppress misalignment of the first member 51 and twisting between the first member 51 and the electric wire W. When the slide body 210 moves, the first member 51 slides against the exterior member 30 and the electric wire W. Furthermore, due to vibrations caused when the vehicle 100 is traveling, the first member 51 slides against the exterior member 30 and the electric wire W. If misalignment of the first member 51 or twisting between the first member 51 and the electric wire W occurs due to the above-mentioned sliding, there is a possibility that the biasing member 50 will not be able to generate sufficient pressing forces F1, F2.

[0045] In the biasing member 50 of this embodiment, the second member 52 supports the first member 51, and the posture and shape of the first member 51 can be stabilized. In addition, since the second member 52 supports both the electric wire W and the first member 51, twisting is unlikely to occur between the first member 51 and the electric wire W. Therefore, the wiring structure 1 of this embodiment can suppress variation in the spring performance of the biasing member 50 and suppress the tapered shape of the biasing member 50 at the curved portion.

[0046] In the biasing member 50, the rigidity of the first member 51 against bending may be greater than the rigidity of the second member 52 against bending. In this case, the first member 51 can regulate the tapered shape of the second member 52. As shown in FIG. 6, in the curved portions 33 and 34, the first member 51 is located radially outward of the second member 52.

[0047] A curved portion 51c is formed in the first member 51, and a curved portion 52c is formed in the second member 52. The first member 51, which has a relatively high rigidity, can suppress the tapering shape of the curved portion 52c in the second member 52. In FIG. 6, the curved portion 52d shown by the dashed line is a curved portion that would be formed in the second member 52 in the absence of the first member 51. The curved portion 52d has a tapered shape. The first member 51 supports the second member 52 from the outside in the radial direction to suppress the tapered shape. By suppressing the tapered shape of the second member 52, a decrease in the bending radius of the electric wire W is suppressed.

[0048] As described above, the wiring structure 1 of the present embodiment has the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, and the biasing member 50. The first fixing portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixing portion 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle front-rear direction X with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 has a first end portion 30a held by the first fixing portion 10 and a second end portion 30b held by the second fixing portion 20. The electric wire W and the biasing member 50 are inserted into the exterior member 30.

[0049] The biasing member 50 forms a curved portion that curves toward the vehicle front-rear direction X between the first end 30a and the second end 30b of the exterior member 30. The biasing member 50 has a rod-shaped first member 51 and a plate-shaped second member 52 that supports the electric wire W and the first member 51. The rod-shaped first member 51 has higher durability against bending for the same bending rigidity compared to a plate-shaped member. Therefore, the wiring structure 1 of this embodiment can suppress the tapered shape of the biasing member 50 at the curved portion.

[0050] The bending rigidity of the first member 51 may be greater than the bending rigidity of the second member 52. In this case, the first member 51 may be disposed radially outward from the second member 52 in the curved portion. The first member 51 disposed on the outer side can suppress the tapered shape of the second member 52 in the curved portion.

[0051] The electric wire W and the first member 51 may be disposed radially inward relative to the second member 52. The exterior member 30 is not limited to a so-called corrugated tube. The exterior member 30 may be a braided tube or any other member used as an exterior member.

[0052] The cross-sectional shape of the rod-shaped first member 51 is not limited to a circle. The cross-sectional shape of the first member 51 may be a polygon or another shape. The biasing member 50 may have a plurality of rod-shaped first members 51.

[0053] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
