[0006] Technical problem that the invention aims to solve

[0007] The inventor of the present application has studied the case where a rigid force-applying member is arranged inside the outer member when the wiring structure between the vehicle body and the sliding body has an outer member. Here, from the viewpoint of ensuring the durability of the force-applying member against bending, it is preferable to reduce the rigidity of the force-applying member. On the other hand, in the case where the outer member and the force-applying member form a curved portion, if the rigidity of the force-applying member is small, a tapered shape is easily formed in the curved portion. When the shape of the curved portion is tapered, the bending radius of the wire is reduced.

[0008] An object of the present invention is to provide a wiring structure capable of suppressing the tapered shape of a biasing member.

[0009] Technical solutions to the problem

[0010] The wiring structure of the present invention is characterized in that it includes: a first fixing portion, the first fixing portion is fixed to the body of the vehicle; a second fixing portion, the second fixing portion is fixed to a sliding body, and the sliding body moves along the front-rear direction of the vehicle relative to an opening portion provided on the roof of the body; an exterior component, the exterior component has a first end portion held by the first fixing portion and a second end portion held by the second fixing portion; an electric wire, the electric wire is inserted through the exterior component; and a force-applying component, the force-applying component is inserted through the exterior component, and the force-applying component forms a bent portion bent toward the front-rear direction of the vehicle between the first end portion and the second end portion of the exterior component, the force-applying component having a rod-shaped first component and a plate-shaped second component supporting the electric wire and the first component.

[0011] Effects of the Invention

[0012] The force-applying member of the wiring structure involved in the present invention comprises a rod-shaped first member and a plate-shaped second member supporting the electric wire and the first member. Compared with the plate-shaped member, the rod-shaped first member has high durability against bending with the same bending rigidity. That is, the rod-shaped first member can have high bending rigidity while ensuring durability. According to the wiring structure of the present invention, the tapering shape of the force-applying member can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] [Implementation Method]

[0046] Reference Figures 1 to 6 , an embodiment is described. This embodiment relates to a wiring structure. Figure 1 and Figure 2 is a side view of a wiring structure of an embodiment, Figure 3 is a cross-sectional view of a wiring structure according to an embodiment, Figure 4 is a side view of a wiring structure of an embodiment, Figure 5 This is a diagram to explain the tapered shape. Figure 6 It is a side view of the wiring structure of the embodiment. Figure 3 Show Figure 4 III-III section.

[0047] like Figure 1 As shown, the wiring structure 1 of the embodiment can be applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, a car 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 covering a vehicle interior. The roof 120 has an opening 120a that opens upward.

[0048] The vehicle 100 has a sunroof 200 for opening and closing an opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a component that slides relative to the opening 120a along the vehicle front-rear direction X. The sliding body 210 of this embodiment is a plate-shaped component that closes the opening 120a or opens the opening 120a. The sliding body 210 may also be a glass structured to allow light to pass through.

[0049] The sunroof 200 has a mechanism such as a link mechanism that moves the slide 210 along a predetermined path, and a driving source such as a motor that operates the mechanism. The sunroof 200 moves the slide 210 between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. Figure 1 2 shows the sliding body 210 in the fully closed position. Figure 2 The slide body 210 is shown in the fully open position.

[0050] 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 for moving the slider 210 and guides the mechanism in the vehicle front-rear direction X. The rail 220 also supports the exterior member 30 and forms a first extension portion 31 on the exterior member 30 .

[0051] The sunroof 200 of this embodiment allows the sliding body 210 to move along the Figure 2 The movement of the sliding body 210 along the path AR0 includes movement along the vehicle front-rear direction X and movement along the vehicle up-down direction Y. When the sliding body 210 moves from the fully closed position to the fully open position, as shown in FIG. Figure 2 As indicated by the middle arrow AR1 , the slider 210 moves toward the upper side Y1 in the vehicle up-down direction Y, and moves toward the rear side X2 in the vehicle front-rear direction X.

[0052] In contrast, when the slider 210 moves from the fully open position toward the fully closed position, the slider 210 moves toward the front side X1 in the vehicle front-rear direction X and toward the lower side Y2 in the vehicle up-down direction Y.

[0053] like Figures 1 to 3 As shown, the wiring structure 1 includes a first fixing portion 10, a second fixing portion 20, an exterior member 30, electric wires W, and a biasing member 50. The exterior member 30 and the electric wires W constitute a wire harness routed between the vehicle body 110 and the slider 210.

[0054] The first fixing portion 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 may also be a protector for protecting the electric wire W. The first fixing portion 10 is molded of, for example, an insulating synthetic resin. The first fixing portion 10 has a space for laying the electric wire W and has a holding structure for holding the exterior member 30.

[0055] The second fixing portion 20 is a component fixed to the sliding body 210 of the sunroof 200. The second fixing portion 20 may also be a protector for protecting the electric wire W. The second fixing portion 20 is molded of, for example, an insulating synthetic resin. The second fixing portion 20 has a space for laying the electric wire W and has a holding structure for holding the exterior member 30.

[0056] The exterior member 30 is an elastically deformable cylindrical member. The exterior member 30 is, for example, a member called a bellows. The exterior member 30 is molded from, for example, an insulating synthetic resin. The exterior member 30 may also have a bellows shape.

[0057] The exterior member 30 has a first end portion 30a held by the first fixing portion 10 and a second end portion 30b held by the second fixing portion 20. The first fixing portion 10 holds the first end portion 30a in a manner 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 portion 30a in a manner that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0058] The second fixing portion 20 holds the second end portion 30b so that the exterior member 30 extends from the second fixing portion 20 along the slider 210 in the vehicle longitudinal direction X. The second fixing portion 20 of this embodiment holds the second end portion 30b so that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.

[0059] The outer member 30 is provided with an electric wire W and a force-applying member 50. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating layer. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit bodies. The electric wire W led out from the first end 30a is connected to a power source or a control device disposed on the vehicle body 110. The electric wire W led out from the second end 30b is connected to a load disposed on the side of the sliding body 210. The load disposed on the sliding body 210 may be, for example, a lighting device, a dimming film disposed on the glass of the sliding body 210, or other electrical loads.

[0060] like Figure 1 and Figure 2 As shown, the exterior member 30 includes a curved portion 33 and a curved portion 34 that are curved in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b. The curved portion 33 and the curved portion 34 are formed by the urging member 50 . Figure 1The curved portion 33 shown is a curved portion formed on the exterior member 30 when the slider 210 is in the fully closed position. The curved portion 33 has a radius R1. Figure 2 The curved portion 34 shown is a curved portion formed on the exterior member 30 when the slider 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W formed with the curved portions 33 and 34 has a U-shape or a J-shape.

[0061] like Figure 1 As shown, when the slider 210 is in the fully closed position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0062] like Figure 2 As shown, when the slider 210 is in the fully open position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the second distance L2. The radius R2 of the curved portion 34 is half the size of the second distance L2.

[0063] In the sunroof 200 of the present 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. In addition, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed on the force applying member 50 when the sliding body 210 is in other positions. In other words, when the sliding body 210 is in the fully closed position, the radius of the curved shape formed on the force applying member 50 is minimized.

[0064] The second end portion 30b of the exterior member 30 moves together with the slider 210. At this time, the exterior member 30 follows the movement of the second fixing portion 20 while gradually changing the position where the curved shape is formed.

[0065] The biasing member 50 of this embodiment is a member that presses the exterior member 30 toward the sliding body 210. Figure 1 and Figure 2 As shown, the urging member 50 forms a curved portion 33 and a curved portion 34 that are curved in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b of the exterior member 30 .

[0066] like Figure 3 As shown, the cross-sectional shape of the exterior member 30 of the present embodiment is a rectangle. The urging member 50 includes 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.

[0067] The first member 51 is a rod-shaped member extending 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 30 a to the second end 30 b . The first member 51 in the example is a round rod having a circular cross-sectional shape.

[0068] The second component 52 is a plate-shaped component that supports the wires W and the first component 51. The second component 52 is arranged over the entire length of the exterior component 30, for example, from the first end 30a to the second end 30b. The shape of the second component 52 in the example is a flat plate with a rectangular cross-sectional shape. The second component 52 extends from one end to the other end in the width direction H in the internal space of the exterior component 30. The second component 52 is respectively opposite to the plurality of wires W and the first component 51 in the vehicle up-down direction Y. In other words, the second component 52 has a width that can support the first component 51 and the plurality of wires W.

[0069] Figure 3 The second member 52 is arranged on the inner side with respect to the first member 51 and the wire W. Therefore, in the curved portion 33 and the curved portion 34 , the second member 52 is located on the inner side with respect to the first member 51 and the wire W in the radial direction.

[0070] like Figure 4 As shown, the exterior member 30 , the electric wire W, and the urging member 50 are arranged in a state bent in a U-shape or a J-shape. That is, the urging member 50 extends from the first fixing portion 10 to the second fixing portion 20 with a bent portion 54 .

[0071] The force applying member 50 bent to have the bent portion 54 applies a pressing force F1 and a pressing force F2 to the exterior member 30. The pressing force F1 is a force in the vehicle vertical direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle vertical direction Y, and presses the exterior member 30 toward the slider 210. The pressing forces F1 and F2 are restoring forces generated by the bent force applying member 50.

[0072] The pressing force F1 and the pressing force F2 are forces including 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 slider 210 and the rail 220 by the combined force of the restoring forces of the two members 51 and 52.

[0073] The pressing force F1 forms a first extension portion 31 on the exterior member 30. The pressing force F2 forms a second extension portion 32 on the exterior member 30. Figure 2As shown in the figure, the second extension portion 32 is a portion extending along the surface 210a on the vehicle compartment side of the sliding body 210. The surface 210a on the vehicle compartment side is a surface facing the lower side Y2. When the surface 210a on the vehicle compartment side is a plane, the second extension portion 32 is formed in a straight line. When the surface 210a on the vehicle compartment side has a curved shape, the second extension portion 32 has a curved shape along the surface 210a on the vehicle compartment side.

[0074] The force applying member 50 of the present embodiment is configured to press the outer 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 opened position. In other words, the force applying member 50 has a rigidity that enables the outer member 30 to always be pressed toward the sliding body 210 and in contact. Therefore, the wiring structure 1 of the present embodiment can stabilize the shape of the outer member 30. The force applying member 50 can make the outer member 30 contact the sliding body 210 by overcoming external forces such as vibration generated during driving, for example.

[0075] As described below, the wiring structure 1 of the present embodiment can suppress the tapered shape of the biasing member 50 in the bent portion. Figure 5 , the tapering shape is explained. Figure 5 2 shows a tapered shape formed in the force applying member 150 of the comparative example. The force applying member 150 of the comparative example has the same plate shape as the second member 52. The force applying member 150 of the comparative example does not include a rod-shaped member like the first member 51. The force applying member 150 is formed with a curved portion 151 and a straight portion 152. The straight portion 152 is a portion extending in a straight line, and is formed along the sliding body 210 and the rail 220, respectively.

[0076] The curved portion 151 has a front end portion 151a and two terminal portions 151b. The front end portion 151a is the central portion of the curved portion 151 and has a convex shape facing the vehicle front-rear direction X. The terminal portion 151b is the end of the curved portion 151 in the vehicle up-down direction Y and is a portion connected to the straight portion 152. The curved portion 151 has a tapered shape. More specifically, the shape of the curved portion 151 is a shape in which the bending radius decreases as it approaches the front end portion 151a from the terminal portion 151b.

[0077] exist Figure 5 , an imaginary circle IC is shown. The imaginary circle IC is a circle whose diameter is the distance L0 from the rail 220 to the slider 210 in the vehicle vertical direction Y. The bending radius of the front end portion 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 front end portion 151a is smaller than the bending radius of the terminal portion 151b. When the rigidity of the force-applying member 150 is small, such a tapered shape is easily formed in the curved portion 151.

[0078] As a means of 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, if the thickness of the urging member 150 is increased, the durability of the urging member 150 against bending may be reduced.

[0079] In the wiring structure 1 of the present embodiment, the force applying member 50 includes a rod-shaped first member 51. When the rod-shaped member and the plate-shaped member have the same bending rigidity, the rod-shaped member has higher durability against bending than the plate-shaped member. In other words, the rod-shaped member can ensure the same durability against bending and has higher rigidity than the plate-shaped member. Therefore, the wiring structure 1 of the present embodiment can suppress the tapered shape of the force applying member 50 at the bent portion.

[0080] In addition, the wiring structure 1 of the present embodiment includes a plate-shaped second member 52 that supports the electric wire W and the first member 51. The second member 52 can suppress the positional deviation of the first member 51 and the torsion between the first member 51 and the electric wire W. When the slider 210 moves, the first member 51 slides relative to the exterior member 30 and the electric wire W. In addition, due to the vibration of the vehicle 100 during driving, the first member 51 slides relative to the exterior member 30 and the electric wire W. If the positional deviation of the first member 51 and the torsion between the first member 51 and the electric wire W caused by the above-mentioned sliding occur, the force applying member 50 may not be able to generate sufficient pressing force F1 and pressing force F2.

[0081] In the urging member 50 of the present 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, by making the second member 52 support both the wire W and the first member 51, it is difficult to cause torsion between the first member 51 and the wire W. Therefore, the wiring structure 1 of the present embodiment can suppress the deviation of the spring performance of the urging member 50 and suppress the tapered shape of the urging member 50 at the bent portion.

[0082] In the force applying member 50, 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 can restrict the tapering shape of the second member 52. Figure 6 As shown, in the curved portions 33 and 34 , the first member 51 is located radially outward from the second member 52 .

[0083] The first member 51 has a curved portion 51c, and the second member 52 has a curved portion 52c. The first member 51 having relatively high rigidity can suppress the tapering of the curved portion 52c in the second member 52. Figure 6In the figure, the curved portion 52d indicated by the single-dot chain line is a curved portion formed in the second member 52 without the first member 51. The curved portion 52d has a tapered shape. The first member 51 supports the second member 52 from the outer side in the radial direction to suppress the tapered shape. By suppressing the tapered shape of the second member 52, the reduction in the bending radius of the wire W is suppressed.

[0084] 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 force applying member 50. The first fixing portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixing portion 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle front-rear direction X relative to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 includes the first end portion 30a held by the first fixing portion 10 and the second end portion 30b held by the second fixing portion 20. The electric wire W and the force applying member 50 are inserted through the exterior member 30.

[0085] The urging member 50 forms a curved portion that is 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. The urging member 50 includes a rod-shaped first member 51 and a plate-shaped second member 52 that supports the electric wire W and the first member 51. Compared with the plate-shaped member, the rod-shaped first member 51 has higher durability against bending for the same bending rigidity. Therefore, the wiring structure 1 of the present embodiment can suppress the tapered shape of the urging member 50 in the curved portion.

[0086] The bending rigidity of the first member 51 may be greater than that of the second member 52. In this case, the first member 51 may be arranged radially outwardly of the second member 52 at the curved portion. The first member 51 arranged outwardly can suppress the tapering shape of the second member 52 at the curved portion.

[0087] In addition, the wire W and the first member 51 may be arranged radially inwardly 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 a member used as another exterior member.

[0088] 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 other shapes. The urging member 50 may include a plurality of rod-shaped first members 51 .

[0089] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
