[0006] Technical problem that the invention aims to solve

[0007] The inventor of the present application has studied that in the case where the wiring structure between the vehicle body and the sliding body has an exterior component, a rigid force-applying component is arranged inside the exterior component. Here, from the viewpoint of ensuring the durability of the force-applying component against bending, it is preferable to reduce the rigidity of the force-applying component. On the other hand, in the case where a curved portion is formed between the exterior component and the force-applying component, if the rigidity of the force-applying component is low, a tapered shape is easily formed in the curved portion. When the shape of the curved portion is tapered, the curvature 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 comprises: a first fixing portion fixed to a vehicle body; a second fixing portion fixed to a sliding body, the sliding body moving in the front-rear direction of the vehicle relative to an opening provided in a roof of the vehicle body; an exterior member having a first end portion held by the first fixing portion and a second end portion held by the second fixing portion; an electric wire inserted through the exterior member; and a rod-shaped or plate-shaped urging member inserted through the exterior member, the urging member forming a curved portion curved in the front-rear direction of the vehicle between the first end portion and the second end portion of the exterior member, the urging member having an arc portion, the arc portion being a portion forming the curved portion when the sliding body is located at an end portion of a sliding range, the arc portion being formed in an arc shape having a predetermined radius in a state where no external force is applied to the urging member, the predetermined radius being larger than half of a distance in the vehicle vertical direction between the second end portion and the first end portion when the sliding body is located at the end portion of the sliding range.

[0011] Effects of the Invention

[0012] The force-applying member of the wiring structure of the present invention has a portion that forms the curved portion when the sliding body is located at the end of the sliding range, that is, an arc portion. The arc portion is formed into an arc shape with a predetermined radius when no external force acts on the force-applying member. 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

[0041] like Figure 1 As shown, the wiring structure 1 of the embodiment is 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.

[0042] 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 structure that allows light to pass through.

[0043] 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.

[0044] 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 .

[0045] The sunroof 200 of this embodiment allows the sliding body 210 to move along the Figure 2The 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The outer member 30 has an electric wire W and a force-applying member 50 inserted therethrough. 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 of a glass disposed on the sliding body 210, or other electrical loads.

[0054] like Figure 1 and Figure 2 As shown, the exterior member 30 has bent portions 33 and 34 that are bent in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b . The bent portions 33 and 34 are formed by the urging member 50 . Figure 1 The 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.

[0055] 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.

[0056] 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.

[0057] 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, the size of the radius of the curved shape formed on the force applying member 50 is the smallest when the sliding body 210 is in the fully closed position.

[0058] 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.

[0059] The urging member 50 of the present embodiment is a member that presses the exterior member 30 toward the slider 210. The urging member 50 of the present embodiment is a rod-shaped or plate-shaped member that is elastically deformable. The urging member 50 is formed of, for example, metal or resin.

[0060] like Figure 3 As shown in FIG. 1 , the cross-sectional shape of the exterior member 30 of the present embodiment is a rectangle. The cross-sectional shape of the urging member 50 of the example is a rectangle. That is, the urging member 50 of the example is a plate-shaped member. Figure 3 The force applying member 50 is arranged outside the wire W. Therefore, in the curved portions 33 and 34, the force applying member 50 is located outside the wire W in the radial direction. Figure 3 As shown, the urging member 50 applies pressing forces F1 and F2 to the exterior member 30 .

[0061] 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 .

[0062] The force applying member 50 bent so as to have the bent portion 54 forms the bent portions 33 and 34 on the exterior member 30, and 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.

[0063] 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.

[0064] The force applying member 50 of the present 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 opened position. In other words, the force applying member 50 has a rigidity capable of always pressing the exterior member 30 toward the sliding body 210 so that the exterior member 30 and the sliding body 210 are in contact. Therefore, the wiring structure 1 of the present embodiment can stabilize the shape of the exterior member 30. The force applying member 50 can, for example, overcome external forces such as vibration generated during driving and make the exterior member 30 and the sliding body 210 in contact.

[0065] As described below, the wiring structure 1 of the present embodiment can suppress the tapering of the biasing member 50 in the bent portions 33 and 34. Figure 5 2 shows the tapered shape of the force applying member 150 formed in the comparative example. The force applying member 150 of the comparative example is a rod-shaped or flat-plate-shaped member. The force applying member 150 is a straight-line member bent and arranged between the sliding body 210 and the rail 220. The force applying member 150 is sandwiched by the sliding body 210 and the rail 220 to form 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.

[0066] 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 radius of curvature decreases as it approaches the front end portion 151a from the terminal portion 151b.

[0067] 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 up-down direction Y. The radius of curvature 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 radius of curvature of the front end portion 151a is smaller than the radius of curvature of the terminal portion 151b. When the linear force-applying member 150 is folded back 180 degrees, a deviation in the radius of curvature occurs in the greatly deformed curved portion 151, which easily leads to such a tapered shape.

[0068] like Figure 6 As shown, the force applying member 50 of this embodiment has an arc portion 53. The arc portion 53 is a portion forming the curved portions 33 and 34 of the exterior member 30. The force applying member 50 of the example 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 forming the curved portion 33 when the sliding body 210 is in the fully closed position. The second arc portion 53B is a portion forming the curved portion 34 when the sliding body 210 is in the fully open position.

[0069] The urging 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 arranged on the second end 50b side relative to the second arc portion 53B.

[0070] The arc portion 53 is formed in an arc shape having a predetermined radius when no external force acts on the urging member 50. The state in which no external force acts on the urging member 50 is, for example, a state in which no bending moment acts on the urging member 50.

[0071] When the urging member 50 is formed of metal, the arc portion 53 is formed, for example, by bending a metal rod or a metal plate, etc. When the urging member 50 is formed of resin, the arc portion 53 is formed, for example, by injection molding.

[0072] In the urging member 50, the portion other than the arc portion 53 is formed into a straight line, for example. The first arc portion 53A is formed into an arc shape having a radius R11 when not subjected to external force. The second arc portion 53B is formed into an arc shape having a radius R12 when not subjected to external force.

[0073] The radius R11 of the first arc portion 53A is greater than the radius R1 of the curved portion 33, and the radius R12 of the second arc portion 53B is greater than the radius R2 of the curved portion 34. That is, the radius R11 of the first arc portion 53A is greater than half of the first distance L1, and the radius R12 of the second arc portion 53B is greater than half of the second distance L2.

[0074] As described below, the arc portion 53 is deformed so that the curvature radius decreases when forming the curved portions 33 and 34. For example, as described below, the curvature radius of the first arc portion 53A decreases when forming the curved portion 33.

[0075] exist Figure 7 , the force applying member 50 is shown when the sliding body 210 is in a half-open position. Figure 7This is a diagram for explaining the shape of the urging member 50, and the exterior member 30 is omitted. As indicated by arrow AR3, the slider 210 moves toward the front side X1 in the vehicle front-rear direction X toward the fully closed position. Figure 7 In the illustrated urging member 50 , the first arc portion 53A projects toward the front side X1 in the front-rear direction X of the vehicle.

[0076] The force applying member 50 is pressed by the sliding body 210 and the rail 220 in the vehicle vertical direction Y. In other words, a bending moment generated by the force received from the sliding body 210 and the rail 220 acts on the force applying member 50. The radius R13 of the first arc portion 53A at this time is smaller than the radius R11 when no external force acts, and is larger than the radius R1 of the curved portion 33 when fully closed. The force applying member 50 is formed with curved portions 55 and 56 adjacent to the first arc portion 53A. The curved portion 55 is formed between one end of the first arc 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 portion 53A and a straight portion 58 along the sliding body 210.

[0077] Figure 8 FIG. 5 shows the force applying member 50 when the sliding body 210 reaches the fully closed position. Figure 7 The distance in the state of being closed is small. The curvature 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 force-applying member 50 forms the curved portion 33 on the outer member 30 through the first arc portion 53A. The curvature radius R1 of the first arc portion 53A is smaller than the radius R11 in the no-load state where no bending moment acts. Therefore, the force-applying member 50 can apply pressing forces F1 and F2 to the outer member 30.

[0078] In the wiring structure 1 of the present embodiment, the first arc portion 53A forming the curved portion 33 is pre-formed into an arc shape. The amount of deformation of the first arc portion 53A when deformed into a curved shape of radius R1 is smaller than the amount of deformation when a straight-line component is deformed into a curved shape of radius R1. That is, the stress of the first arc portion 53A when the first arc portion 53A has a curved shape of radius R1 is smaller than the stress when a straight-line component is deformed into a curved shape of radius R1. By suppressing the amount of deformation of the first arc portion 53A from a no-load state where no bending moment is applied, it is less likely that a tapered shape will be generated in the first arc portion 53A. In addition, by suppressing the stress generated in the first arc portion 53A when the curved portion 33 is formed, it is less likely that a tapered shape will be generated in the first arc portion 53A.

[0079] Figure 6The arc length AL1 of the first arc portion 53A shown is determined based on, for example, the radius R1 of the curved portion 33 when fully closed. The length of the circumference of the circle having the radius R1 is set to C1. In this case, the size of the arc length AL1 is determined, for example, by formula (1). In other words, the arc length AL1 is greater than the length of the semicircle of the circle having the radius R1. As a result, stress concentration is not easily generated in the portion of the force-applying member 50 where the curved portion 33 is formed, so that the tapered shape can be suppressed.

[0080] AL1≥C1 / 2 (1)

[0081] In the wiring structure 1 of the present embodiment, the second arc portion 53B forming the bent portion 34 is pre-formed in an arc shape. The amount of deformation when the second arc portion 53B is deformed into a curved shape with a radius R2 is smaller than the amount of deformation when a straight member is deformed into a curved shape with a radius R2. By suppressing the amount of deformation of the second arc portion 53B from a no-load state where a bending moment is not applied, it is not easy to form a tapered shape in the second arc portion 53B. In addition, by suppressing the stress generated in the second arc portion 53B when the bent portion 34 is formed, it is not easy to form a tapered shape in the second arc portion 53B.

[0082] Figure 6 The arc length AL2 of the second arc portion 53B shown is determined, for example, based on the radius R2 of the curved portion 34 when fully opened. The length of the circumference of the circle having the radius R2 is set to C2. In this case, the size of the arc length AL2 is determined, for example, by formula (2). In other words, the arc length AL2 is greater than the length of the semicircle of the circle having the radius R2. As a result, it is difficult for stress concentration to occur in the portion of the force-applying member 50 where the curved portion 34 is formed, so that the tapering shape can be suppressed.

[0083] AL2≥C2 / 2 (2)

[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 rod-shaped or plate-shaped 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 portion 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 curved portions 33 and 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. The urging member 50 has an arc portion 53. The arc portion 53 is a portion that forms the curved portions 33 and 34 when the sliding body 210 is located at the end of the sliding range. In the present embodiment, the fully closed position and the fully open position of the sliding body 210 are the ends of the sliding range.

[0086] The arc portion 53 is formed into an arc shape having a predetermined radius R11, R12 when no external force is applied to the force applying member 50. The predetermined radius R11, R12 is larger than half of the distance L1, L2 of the second end portion 30b relative to the first end portion 30a along the vehicle vertical direction Y 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 larger than half of the first distance L1 when the sliding body 210 is in the fully closed position. The wiring structure 1 of the present embodiment suppresses the tapered shape of the force applying member 50 in the curved portions 33, 34 by pre-forming the arc portion 53 into an arc shape.

[0087] In the sliding range of the sliding body 210 of the present 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 sliding body 210 closes the opening 120a, and the fully open position is a position where the sliding body 210 opens the opening 120a. The force applying member 50 has a first arc portion 53A and a second arc portion 53B as the arc portion 53.

[0088] The first arc portion 53A forms the curved portion 33 when the slider 210 is in the fully closed position. The second arc portion 53B forms the curved portion 34 when the slider 210 is in the fully open position. The wiring structure 1 of this embodiment can suppress the tapered shape of the urging member 50 when the slider 210 is in the fully closed position and when the slider 210 is in the fully open position.

[0089] The shape of the arc portion 53 in the unloaded state is not limited to Figure 6 For example, Fig. 9 As shown, the central angle of the arc portion 53 may also be less than 180 degrees. The central angle of the arc portion 53 may be, for example, 90 degrees, 120 degrees, 150 degrees, or other angles.

[0090] In the force applying member 50, the shape of the arc portion 53 may include portions with different curvature radii. For example, in the first arc portion 53A, the curvature radius of the central portion 53c of the first arc portion 53A may be larger than the curvature radii of the two end portions 53e of the first arc portion 53A. In this case, the central portion 53c becomes relatively flat compared to the two end portions 53e.

[0091] like Fig.10 As shown in FIG. 1 , in the arc portion 53, a curved shape may be provided in the connecting portion 53j connected to the straight portion. The curvature direction of the connecting portion 53j is opposite to the curvature direction of the arc portion 53. Fig.10 In the arc portion 53 shown, the connecting portion 53 j is bent to form an inflection point.

[0092] In addition, the force-applying member 50 may also be a rod-shaped member with a circular cross-sectional shape. The force-applying member 50 may also be a rod-shaped member with a polygonal cross-sectional shape. The outer casing 30 is not limited to the so-called corrugated tube. The outer casing 30 may be a braided tube or other member used as an outer casing. The force-applying member 50 may also be arranged on the inner side relative to the wire W. That is, the force-applying member 50 may also be arranged on the inner side of the wire W in the radial direction in the curved portions 33 and 34.

[0093] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
