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 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.

[0049] 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 .

[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 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.

[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 member fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 may 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.

[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] 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.

[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 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 2As 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 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 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 3 As 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 via the wire W.

[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, the wiring structure 1 of the present embodiment is configured such that the electric wire W has a surplus length remaining portion Ws inside the exterior member 30 . Figure 5 The electric wire W and the urging member 50 are shown before being inserted through the exterior member 30. The urging member 50 has a flat plate shape before being inserted through the exterior member 30. The electric wire W is held by the holding portion 2 with an extra length remaining portion Ws. Figure 5 The holding portion 2 holds the electric wire W by fixing the electric wire W to the urging member 50 . The holding portion 2 holds the electric wire W by fixing at least two locations of the electric wire W to the urging member 50 .

[0072] The holding portion 2 is a member such as an adhesive tape or a binding band that can fix the electric wire W to the urging member 50 . Figure 5The two retaining portions 2 fix the electric wire W to the ends on both sides of the force applying member 50. The length of the excess length retaining portion Ws in the electric wire W is longer than the length L between the two retaining portions 2 in the force applying member 50. Therefore, the excess length retaining portion Ws can be bent and extended along the force applying member 50 between the two retaining portions 2. The excess length retaining portion Ws of the present embodiment is a portion having excess length relative to the exterior member 30 and the force applying member 50. That is, the excess length retaining portion Ws is a bendable portion having a length that is as bendable as possible inside the exterior member 30.

[0073] The urging member 50 and the electric wire W fixed to the urging member 50 are inserted through the exterior member 30. The exterior member 30 and the urging member 50 are held by the first fixing portion 10 and the second fixing portion 20. Thus, the urging member 50 is formed with a bent portion 54, and the exterior member 30 is formed with a bent shape corresponding to the bent portion 54.

[0074] Figure 6 The electric wire W is shown at the curved portion 35 of the exterior member 30. The curved portion 35 is a curved portion formed by the curved portion 54 of the force applying member 50. The curved portion 35 may be the curved portion 33 when the slider 210 is in the fully closed position, the curved portion 34 when the slider 210 is in the fully open position, or the curved portion when the slider 210 is in other positions.

[0075] By providing the extra length portion Ws to the electric wire W inside the exterior member 30, excessive stress is less likely to be generated on the electric wire W at the bent portion 35. The electric wire W having the extra length portion Ws extends while being bent inside the exterior member 30. In this case, the electric wire W forms a meandering shape inside the exterior member 30, for example. Figure 6 The wire shown has a meandering portion Wa that meanders along the support surface of the urging member 50 formed inside the exterior member 30. When the bent portion 35 is formed in the exterior member 30, the wire W having the extra length remaining portion Ws is deformed by bending and twisting.

[0076] As a comparative example, when the electric wire W does not have the extra length retention portion Ws, when the outer casing 30 is deformed, the electric wire W mainly undergoes bending deformation corresponding to the bent portion 35. In contrast, in the electric wire W of the present embodiment having the extra length retention portion Ws, not only bending but also twisting deformation occurs. As a result, the stress generated in the electric wire W when following the deformation of the outer casing 30 is relieved, and the bending durability of the electric wire W is improved. In addition, when the electric wire W has the extra length retention portion Ws, it is not easy for an excessive tensile force to act on the electric wire W when the bent portion 35 is formed. Therefore, the durability of the electric wire W is improved.

[0077] Reference Figures 7 to 10 , a wiring method for wiring the electric wires W relative to the urging member 50 will be described. Figure 7The wire assembly 60 manufactured in the jig 300 is shown. The wire assembly 60 includes a biasing member 50, wires W, and a plurality of holding portions 2. Connectors 70 are connected to both ends of the wires W. The wire assembly 60 is inserted into the exterior member 30 and mounted on the vehicle body 110 together with the exterior member 30.

[0078] like Figure 7 and Figure 8 As shown, the jig 300 has a plate-shaped main body 310 and a pair of support parts 320. The main body 310 is, for example, rectangular in shape. The support parts 320 support the force application member 50 in a bent state. The support parts 320 protrude from the support surface 310a of the main body 310 in a direction orthogonal to the support surface 310a.

[0079] The shape of the support portion 320 when viewed from above is generally L-shaped. The pair of support portions 320 are opposed to each other in the width direction D of the main body 310. The support portion 320 has a support wall 321 and an opposing wall 322. The support wall 321 is a portion that supports the end of the force-applying member 50, and extends in a direction orthogonal to the width direction D. The opposing wall 322 protrudes in the width direction D relative to the support wall 321. The opposing wall 322 faces the end surface of the force-applying member 50.

[0080] The wiring method for laying the electric wire W on the force applying member 50 using the jig 300 includes a setting step, a laying step, and a fixing step. The setting step is a step of supporting the force applying member 50 by the jig 300. Fig. 9 As shown, the urging member 50 is provided on the jig 300 in a state where it is elastically deformed to assume a substantially U-shape.

[0081] In the setting process, the operator elastically deforms the force member 50 so as to have an arc-shaped curved portion 55. The operator supports the force member 50 deformed into a shape having the curved portion 55 by the jig 300. Both ends of the force member 50 are supported by a pair of support portions 320. The force member 50 is placed on the support surface 310a so that the ends are along the support wall 321. One end of the force member 50 is supported by one support wall 321. The other end of the force member 50 is supported by another support wall 321. The two support walls 321 support the force member 50 from both sides in the width direction D, and the shape of the force member 50 is maintained in a U shape. The force member 50 supported by the jig 300 has an outer surface 50e. The outer surface 50e is a surface on the outer side of the curved portion 55 in the radial direction. In other words, the outer surface 50e is a surface located on the outer side of the curved portion 55 of the two main surfaces of the force member 50.

[0082] The laying process is a process of laying the electric wire W on the force applying member 50 supported by the jig 300. In the laying process, the operator lays the electric wire W along the force applying member 50 from one end of the force applying member 50 to the other end of the force applying member 50. Fig.10 As shown in FIG. 1 , the electric wire W is arranged along the outer surface 50 e of the urging member 50 . Therefore, the electric wire W is located radially outward with respect to the curved portion 55 .

[0083] The fixing step is a step of fixing the electric wire W to the urging member 50. The operator fixes the electric wire W to at least two locations in the urging member 50 using the holding portion 2. The holding portion 2 is disposed on both sides of the portion of the electric wire W along the curved portion 55. Figure 7 The electric wire assembly 60 includes a holding portion 2g disposed on one side of the curved portion 55 and a holding portion 2h disposed on the other side of the curved portion 55. The holding portions 2g and 2h are disposed near the end of the biasing member 50. The holding portions 2g and 2h are, for example, adhesive tapes, binding bands, and the like.

[0084] When the force applying member 50 is removed from the jig 300, the shape of the force applying member 50 becomes a straight line. Figure 5 As shown, an excess length retention portion Ws is formed on the electric wire W. According to the wiring method using the jig 300, the length of the excess length retention portion Ws can be set to an appropriate length. In addition, when the electric wire W is laid on the force-applying member 50 supported by the jig 300, an excess length may be given to the length of the electric wire W along the force-applying member 50. That is, the electric wire W may be laid in such a manner that the length of the electric wire W along the outer surface 50e is greater than the length of the outer surface 50e.

[0085] It should be noted that the holding portion 2 may hold the electric wire W in such a manner that the extra length remaining portion Ws is positioned at a predetermined position of the exterior member 30 . Fig.11 The wire W shown has a first remaining portion Ws1 and a second remaining portion Ws2 as the extra length remaining portion Ws. The first remaining portion Ws1 is formed as a curved portion 33 when the slider 210 is in the fully closed position. The second remaining portion Ws2 is formed as a curved portion 34 when the slider 210 is in the fully opened position.

[0086] The exterior member 30 includes a first portion 30c that forms a curved portion 33 when fully closed and a second portion 30d that forms a curved portion 34 when fully opened. The first portion 30c is located near the second end portion 30b. The second portion 30d is located near the first end portion 30a. The urging member 50 includes a first portion 50c corresponding to the first portion 30c of the exterior member 30 and a second portion 50d corresponding to the second portion 30d of the exterior member 30.

[0087] The holding portion 2 includes a first holding portion 2a, a second holding portion 2b, a third holding portion 2c, and a fourth holding portion 2d. The first holding portion 2a and the second holding portion 2b form a first retaining portion Ws1 in the first portion 50c. The first holding portion 2a is disposed at one end of the first portion 50c to fix the wire W to the force applying member 50. The second holding portion 2b is disposed at the other end of the first portion 50c to fix the wire W to the force applying member 50.

[0088] The third holding portion 2c and the fourth holding portion 2d form a second retaining portion Ws2 in the second portion 50d. The third holding portion 2c is disposed at one end of the second portion 50d to fix the wire W to the urging member 50. The fourth holding portion 2d is disposed at the other end of the second portion 50d to fix the wire W to the urging member 50.

[0089] The length of the first remaining portion Ws1 is determined based on, for example, the value of the radius R1 of the curved portion 33 and the position of the electric wire W relative to the force applying member 50. The length of the first remaining portion Ws1 may also be determined based on, for example, whether the electric wire W is disposed on the inner side or the outer side in the radial direction relative to the force applying member 50. When the electric wire W is disposed on the outer side relative to the force applying member 50, the length of the first remaining portion Ws1 may be greater than when the electric wire W is disposed on the inner side.

[0090] The length of the second remaining portion Ws2 is determined based on, for example, the value of the radius R2 of the curved portion 34 and the position of the wire W relative to the biasing member 50. When the wire W is arranged outside the biasing member 50, the length of the second remaining portion Ws2 may be greater than when the wire W is arranged inside.

[0091] In the sunroof 200 of the present embodiment, the radius R1 when fully closed is smaller than the radius R2 when fully opened. In this case, the length of the first reserved portion Ws1 may be set to a value greater than the length of the second reserved portion Ws2.

[0092] Fig.11 The electric wire W has a third remaining portion Ws3 as an extra length remaining portion Ws between the first remaining portion Ws1 and the second remaining portion Ws2. That is, the second holding portion 2b and the third holding portion 2c hold the electric wire W in such a manner that the third remaining portion Ws3 is formed between the two holding portions 2b and 2c. When a plurality of extra length remaining portions Ws are formed in this way, uneven distribution of the extra length remaining portions Ws is suppressed.

[0093] In addition, the holding portion 2 is not limited to fixing the electric wire W to the biasing member 50. The holding portion 2 may hold the electric wire W at the fixing portions 10 and 20, for example. Fig.12, a holding portion 2e disposed on the first fixing portion 10 and a holding portion 2f disposed on the second fixing portion 20 are shown. The holding portion 2e may be a clamping member provided integrally with the first fixing portion 10. The holding portion 2f may be a clamping member provided integrally with the second fixing portion 20. These clamping members can hold the electric wire W, and form an excess length retaining portion Ws inside the exterior member 30.

[0094] The holding portion 2e may be a tape, a binding band, or the like that fixes the electric wire W to the first fixing portion 10. The holding portion 2f may be a tape, a binding band, or the like that fixes the electric wire W to the second fixing portion 20.

[0095] The holding parts 2e and 2f hold the wire W so that the wire W has an extra length remaining portion Ws inside the exterior member 30. That is, the holding parts 2e and 2f hold the wire W so that the length of the wire W accommodated inside the exterior member 30 is greater than the length of the exterior member 30.

[0096] When the fixing parts 10 and 20 are provided with the holding parts 2e and 2f, the wiring structure 1 may not include the biasing member 50. In addition, when the wiring structure 1 includes the biasing member 50, the holding parts 2e and 2f may be provided at the fixing parts 10 and 20. In this case, the wire W may not be fixed to the biasing member 50.

[0097] 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 holding portion 2. 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 is inserted through the exterior member 30. The holding portion 2 holds the electric wire W.

[0098] 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 bent portion 35 bent toward the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b. The holding portion 2 holds at least two locations of the electric wire W in such a manner that the electric wire W has an extra length reserved portion Ws inside the exterior member 30. The electric wire W has the extra length reserved portion Ws inside the exterior member 30, so that the stress generated in the electric wire W when the exterior member 30 is deformed is relieved. Therefore, the wiring structure 1 of the present embodiment can improve the durability of the electric wire W against bending.

[0099] The wiring structure 1 may also include a biasing member 50 inserted through the exterior member 30. The holding portion 2 fixes the wire W relative to the biasing member 50, thereby forming an excess length reserved portion Ws along the biasing member 50 in the wire W. With such a structure, the excess length reserved portion Ws can be positioned at a target position inside the exterior member 30.

[0100] The holding portion 2 may be disposed separately in the first fixing portion 10 and the second fixing portion 20. In this case, the holding portion 2e of the first fixing portion 10 and the holding portion 2f of the second fixing portion 20 hold the electric wire W in such a manner that the electric wire W has an extra length remaining portion Ws inside the exterior member 30. With such a structure, the extra length remaining portion Ws can be disposed over the entire length of the exterior member 30.

[0101] The slider 210 of this embodiment moves between a fully closed position closing the opening 120a and a fully open position opening the opening 120a in the vehicle longitudinal direction X. The holder 2 may hold the wire W so that the excess length remaining portion Ws is located at the bent portion 33 when the slider 210 is in the fully closed position. Fig.11 The first holding portion 2a and the second holding portion 2b form a first retaining portion Ws1 located at the curved portion 33. The holding portion 2 may hold the electric wire in such a manner that the excess length retaining portion Ws is located at the curved portion 34 when the slider 210 is at the fully open position. Fig.11 The third retaining portion 2 c and the fourth retaining portion 2 d form a second retaining portion Ws2 located at the bent portion 34 .

[0102] Fig.11 The holding portion 2 shown in the figure forms both the first remaining portion Ws1 and the second remaining portion Ws2 , but the holding portion 2 may form only one of the first remaining portion Ws1 and the second remaining portion Ws2 .

[0103] In the wiring method of the present embodiment, the setting process including the setting process, the laying process and the fixing process is a process of elastically deforming the plate-shaped force member 50 and supporting the force member 50 deformed into a shape having a curved portion 55 by the jig 300. The laying process is a process of laying the wire W on the force member 50 supported by the jig 300. The fixing process is a process of fixing the wire W to at least two locations in the force member 50 by the holding portion 2. In the laying process, the wire W is laid on the surface 50e outside the curved portion 55 in the force member 50. In the fixing process, both sides of the portion of the wire W along the curved portion 55 are fixed to the force member 50 by the holding portion 2. According to the wiring method of the present embodiment, an appropriate excess length retention portion Ws can be formed.

[0104] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
