Figure 3 Show Figure 4 III-III section.

[0046] 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.

[0047] 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.

[0048] The sunroof 200 has a mechanism such as a link mechanism that moves the slide 210 along a predetermined path and a drive 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.

[0049] The rail 220 is fixed to the vehicle body 110 . The rail 220 extends in the vehicle longitudinal direction X. The rail 220 supports a mechanism for moving the slider 210 and guides the mechanism in the vehicle longitudinal direction X. The rail 220 also supports the exterior member 30 and forms a linear first extension portion 31 on the exterior member 30 .

[0050] 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.

[0051] In contrast, when the slider 210 moves from the fully open position to the fully closed position, the slider 210 moves toward the front side X1 in the vehicle front-rear direction X and toward the lower side Y2 in the vehicle up-down direction Y.

[0052] 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.

[0053] The first fixing portion 10 is a component fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 of the present embodiment is fixed to the rail 220. The first fixing portion 10 may be a protector for protecting the electric wire W. The first fixing portion 10 is molded, for example, from 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 component 30.

[0054] 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 component 30.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] A plurality of electric wires W and a force-applying member 50 are inserted through the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating layer. The electric wire W drawn 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 drawn 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 electric loads.

[0059] like Figure 1 and Figure 2 As shown, the exterior member 30 has curved portions 33 and 34 curved in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b. The curved portions 33 and 34 are formed by, for example, 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.

[0060] 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.

[0061] 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.

[0062] In the sunroof 200 of the present 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. 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 the smallest.

[0063] 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.

[0064] 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 plate-shaped member that is elastically deformable. The urging member 50 is formed of metal or resin.

[0065] like Figure 3As shown, the cross-sectional shape of the exterior member 30 of the present embodiment is a rectangle. The shape of the force member 50 of the example is a flat plate. In the force member 50, the cross-sectional shape orthogonal to the axial direction of the force member 50 is a rectangle. The force 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 force member 50 is respectively opposite to the plurality of wires W in the vehicle vertical direction Y. In other words, the force member 50 has a width capable of supporting the plurality of wires W.

[0066] Figure 3 The urging member 50 is arranged on the inner side relative to the wire W. Therefore, in the curved portions 33 and 34, the urging member 50 is located on the inner side relative to 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 .

[0067] 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 .

[0068] The force applying member 50 bent to have the curved 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.

[0069] 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 2 As 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.

[0070] 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 can always press the outer member 30 toward the sliding body 210 so that the outer 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 outer member 30. The force applying member 50 can, for example, overcome external forces such as vibration generated during driving and make the outer member 30 and the sliding body 210 contact.

[0071] As described below, in the wiring structure 1 of the present embodiment, the plurality of electric wires W have a twisted wire portion Wt extending inside the exterior member 30. Figure 5 , the force-applying member 50 and the plurality of electric wires W are shown before being inserted into the exterior member 30. The plurality of electric wires W have a twisted wire portion Wt. In the twisted wire portion Wt, the plurality of electric wires W are twisted together. In the wiring structure 1 of the present embodiment, two electric wires W are arranged between the first fixing portion 10 and the second fixing portion 20. Therefore, the illustrated twisted wire portion Wt is formed by twisting the two electric wires W together. The plurality of electric wires W, for example, have a twisted wire portion Wt extending from the first fixing portion 10 to the second fixing portion 20.

[0072] The two electric wires W of this embodiment are electric wires for supplying electric power to the device arranged in the sliding body 210. In this case, the two electric wires W are connected to the power supply of the vehicle 100 on the vehicle body 110 side. The two electric wires W may be connected to the power supply via an electric junction box or the like.

[0073] The plurality of electric wires W are arranged on the urging member 50 in such a manner that the twisted wire portion Wt extends along the urging member 50. The urging member 50 and the plurality of electric wires W are inserted into the exterior member 30. Thus, the twisted wire portion Wt extends inside the exterior member 30. The ends of the exterior member 30 and the urging member 50 are held by the two fixing portions 10 and 20. The two fixing portions 10 and 20 hold the exterior member 30 in such a manner that a curved portion is formed between the first end portion 30a and the second end portion 30b of the exterior member 30.

[0074] The stranded wire portion Wt of this embodiment can be Figure 5 The first shape shown is Figure 6 Deform between the second shapes shown. Figure 5 The first shape of the stranded wire portion Wt shown has a pitch P1. The pitch P1 is the length in the extension direction Ex of the stranded wire portion Wt, and is the length of one wire W around another wire W. In other words, the pitch P1 is twice the length of the distance between the intersections Wx when viewed from a direction orthogonal to the extension direction Ex of the stranded wire portion Wt.

[0075] The example stranded wire portion Wt is configured to have a first shape when no external force in the extension direction Ex acts on the stranded wire portion Wt. The stranded wire portion Wt in the first shape has an appropriate gap Gp between the two wires W. The gap Gp is ​​determined so that the stranded wire portion Wt can be extended when a tensile force acts on the stranded wire portion Wt.

[0076] like Figure 6 As shown, the second shape of the stranded wire portion Wt has a pitch P2. The pitch P2 of the second shape is longer than the pitch P1 of the first shape. That is, the second shape of the stranded wire portion Wt is elongated in the extension direction Ex relative to the first shape of the stranded wire portion Wt. If a tensile force F3 is applied to the stranded wire portion Wt, the stranded wire portion Wt changes from the first shape to the second shape.

[0077] like Figure 3 As shown, in the wiring structure 1 of the present embodiment, the electric wire W is arranged outside the force-applying member 50 inside the exterior member 30. In this case, when the exterior member 30 and the force-applying member 50 are bent in a U-shape, the tensile force F3 acts on the electric wire W. That is, the tensile force F3 acts on the twisted wire portion Wt inside the bent portion of the exterior member 30. In the twisted wire portion Wt, the portion to which the tensile force F3 acts is stretched by the tensile force F3, thereby forming the second shape.

[0078] The tensile force F3 does not act inside the first extension portion 31 and the second extension portion 32 in the exterior component 30, or the tensile force F3 is small. Therefore, the stranded wire portion Wt becomes the first shape inside the first extension portion 31 and the second extension portion 32. When the position of the curved portion in the exterior component 30 moves due to the movement of the sliding body 210, the position of the stranded wire portion Wt that becomes the second shape also moves. In this way, the stranded wire portion Wt can expand and contract according to the presence or absence of the tensile force F3 and the magnitude of the tensile force F3. The stranded wire portion Wt can absorb the force in the extension direction Ex generated by the deformation of the exterior component 30, thereby reducing the external force acting on each wire W. Therefore, the wiring structure 1 of the present embodiment can alleviate the stress generated in the wire W and suppress the reduction in the durability of the wire W.

[0079] In addition, in the twisted wire portion Wt, the plurality of electric wires W are integrated by intersecting in a spiral shape. Therefore, compared with the case where each electric wire W is independently laid inside the exterior member 30, the electric wire W is less likely to enter the gap between the force-applying member 50 and the exterior member 30. Therefore, the wiring structure 1 of the present embodiment can suppress the reduction in durability of the electric wire W caused by damage to the electric wire W.

[0080] Furthermore, among the plurality of electric wires W, portions protruding from the exterior member 30 may be laid out without being twisted. Figure 7 A wire W is shown having an untwisted portion. Figure 7In the embodiment, the plurality of electric wires W have a twisted wire portion Wt, a first protruding portion W1, and a second protruding portion W2. In the first protruding portion W1 and the second protruding portion W2, the plurality of electric wires W are not twisted with each other. That is, in the first protruding portion W1 and the second protruding portion W2, each electric wire W is independent of each other.

[0081] The twisted wire portion Wt is arranged along the urging member 50 . Figure 7 The stranded wire portion Wt extends from the first end 50a to the second end 50b of the urging member 50. The first end 50a of the urging member 50 corresponds to the first end 30a of the exterior member 30. The second end 50b of the urging member 50 corresponds to the second end 30b of the exterior member 30.

[0082] The stranded wire portion Wt is fixed to the urging member 50 by, for example, a fixing member 40. The fixing member 40 is, for example, disposed at both ends of the urging member 50 and the stranded wire portion Wt. The fixing member 40 is, for example, an adhesive tape or a binding band.

[0083] The first protrusion W1 and the second protrusion W2 are portions of the electric wire W that are closer to the end side than the twisted wire portion Wt. In other words, the portions between the first protrusion W1 and the second protrusion W2 of the electric wire W are twisted together to form the twisted wire portion Wt. The plurality of electric wires W are arranged such that the first protrusion W1 protrudes from the first end portion 50a of the urging member 50 and the second protrusion W2 protrudes from the second end portion 50b of the urging member 50.

[0084] When the urging member 50 and the wire W are inserted into the exterior member 30, the first protrusion W1 protrudes from the first end 30a of the exterior member 30. In addition, the second protrusion W2 protrudes from the second end 30b of the exterior member 30. The first protrusion W1 is connected to the power supply of the vehicle 100. The second protrusion W2 is connected to the device of the slider 210.

[0085] Among the plurality of electric wires W, the first protrusions W1 are arranged in a manner not to be twisted. Figure 8 1 shows a wire W connected to the device 130 on the power supply side of the vehicle 100. Figure 8 As shown, the first protrusion W1 is led outward from the first fixing portion 10. In the first protrusion W1, the portion protruding from the first fixing portion 10 is arranged in a non-twisted manner. It should be noted that the multiple wires W of the first protrusion W1 can also be gathered into one by a belt or the like. The end of the first protrusion W1 is connected to the device 130 on the power supply side. The device 130 on the power supply side is, for example, an electrical junction box.

[0086] Among the plurality of electric wires W, the second protrusions W2 are arranged in a manner not to be twisted. Fig. 9 2 shows a wire W connected to the device 230 disposed on the sliding body 210. Fig. 9As shown, the second protrusion W2 is led outward from the second fixing portion 20. In the second protrusion W2, the portion protruding from the second fixing portion 20 is arranged in a non-twisted manner. It should be noted that the multiple wires W of the second protrusion W2 can also be gathered into one by a belt or the like. The end of the second protrusion W2 is connected to the device 230.

[0087] In addition, the stranded wire portion Wt may also be configured to be able to contract when receiving a compressive force in the extension direction Ex. Fig.10 3 shows the twisted wire portion Wt of the third shape. Fig.10 The stranded wire portion Wt is configured to have a third shape when no external force in the extension direction Ex acts on the stranded wire portion Wt. The stranded wire portion Wt of the third shape has a pitch P3. The pitch P3 is, for example, longer than the pitch P1 of the stranded wire portion Wt of the first shape. The pitch P3 may also be the same length as the pitch P2 of the stranded wire portion Wt of the second shape. Fig.11 As shown, Fig.10 The twisted wire portion Wt is arranged on the inner side relative to the urging member 50.

[0088] When the twisted wire portion Wt is arranged inside the urging member 50, when the exterior member 30 and the urging member 50 are bent in a U-shape, a compressive force F4 acts on the wire W. The twisted wire portion Wt is compressed by the compressive force F4 and deformed into Fig.12 The fourth shape is shown. The stranded wire portion Wt of the fourth shape has a pitch P4. The pitch P4 of the fourth shape is shorter than the pitch P3 of the third shape. By deforming the stranded wire portion Wt so as to reduce the pitch, the stress generated in the wire W is relieved, and the durability of the wire W is suppressed from decreasing.

[0089] In addition, the wiring structure 1 may not have the force applying member 50. In this case, the exterior member 30 is pressed toward the slider 210 by the resilience of the exterior member 30 and the plurality of wires W. In the case where the wiring structure 1 does not have the force applying member 50, the plurality of wires W may have a twisted wire portion Wt of the fifth shape. The twisted wire portion Wt of the fifth shape can be extended in a manner that increases the pitch when the tensile force F3 acts, and can be contracted in a manner that decreases the pitch when the compressive force F4 acts.

[0090] 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, and a plurality of electric wires W inserted into the exterior member 3. 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 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.

[0091] The first fixing portion 10 and the second fixing portion 20 hold the exterior member 30 in such a manner that the exterior member 30 forms a curved portion between the first end portion 30a and the second end portion 30b that is curved toward the vehicle front-rear direction X. The plurality of electric wires W have a twisted wire portion Wt extending inside the exterior member 30. In the twisted wire portion Wt, the plurality of electric wires W are twisted with each other. According to the wiring structure 1 of the present embodiment, when the exterior member 30 forms a curved portion, the twisted wire portion Wt can expand and contract in a manner of increasing and decreasing the pitch to follow the deformation of the exterior member 30. Therefore, the wiring structure 1 of the present embodiment can suppress the reduction in the durability of the electric wires W caused by bending.

[0092] The stranded wire portion Wt may have gaps Gp between the plurality of electric wires W so that the stranded wire portion Wt can extend when receiving the tensile force F3. The stranded wire portion Wt having the gaps Gp between the electric wires W can absorb the tensile force F3 by extending.

[0093] Among the plurality of electric wires W, the portion protruding from the exterior member 30 may be arranged without being twisted. For example, the first protrusion W1 protruding from the first end 30a of the exterior member 30 may be arranged without being twisted. For example, the second protrusion W2 protruding from the second end 30b of the exterior member 30 may be arranged without being twisted. Such a structure can achieve both suppression of a decrease in the durability of the electric wires W caused by bending and a reduction in the total length of the electric wires W.

[0094] The wiring structure 1 may include a biasing member 50 inserted through the exterior member 30 and a fixing member 40 fixing the stranded wire portion Wt to ​​the biasing member 50. The fixing member 40 can control the position of the stranded wire portion Wt to ​​a target position and the pitch of the stranded wire portion Wt to ​​a target size.

[0095] In addition, the exterior member 30 is not limited to a so-called corrugated tube, and the exterior member 30 may be a braided tube or another member used as an exterior member.

[0096] When the wiring structure 1 has the urging member 50, the shape of the urging member 50 is not limited to a plate shape. The urging member 50 may have a rod shape such as a round rod. The ends of the stranded wire portion Wt may be fixed to the first fixing portion 10 and the second fixing portion 20 instead of the urging member 50.

[0097] The pitch of the stranded wire portion Wt may also be different depending on the position in the extension direction Ex. For example, in the exterior member 30, a greater expansion and contraction of the stranded wire portion Wt may be allowed at a portion where a curved portion with a smaller radius R is formed than at a portion where a curved portion with a larger radius R is formed. Figure 3In the arrangement of the stranded wires Wt shown, the tensile force F3 acts on the stranded wires Wt due to the bending of the exterior member 30. In this case, by reducing the pitch of the stranded wires Wt in the first shape, the allowable elongation when the tensile force F3 acts can be increased.

[0098] exist Fig.11 In the arrangement of the stranded wires Wt shown, the compressive force F4 acts on the stranded wires Wt due to the bending of the exterior member 30. In this case, by increasing the pitch of the stranded wires Wt in the third shape, the allowable amount of contraction when the compressive force F4 acts can be increased.

[0099] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
