[0006] Problems to be solved by the invention

[0007] When the wiring structure between the vehicle body and the slider has an exterior component, it is desirable that the shape of the exterior component is stable. For example, the exterior component is held by the slider and the vehicle body in a state where it has a curved portion that is curved in the sliding direction of the slider. When the width of the space for accommodating the exterior component is narrow, the radius of the curved portion of the exterior component becomes smaller. When the shape of the curved portion is unstable, the bending durability of the wires routed inside the exterior component may be affected.

[0008] An object of the present invention is to provide a wiring structure capable of stabilizing the shape of an exterior member.

[0009] Means for solving problems

[0010] The wiring structure of the present invention is characterized in that it comprises: a first fixing portion, which is fixed to the body of a vehicle; a second fixing portion, which 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 vehicle body; an exterior component, which is formed by connecting a plurality of tubular components that can rotate relative to each other, and 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, which is inserted through the exterior component; and a force applying component, which is inserted through the exterior component and presses the exterior component toward the sliding body, and the sliding body is in a fully closed position to close the opening and in a fully closed position to close the opening. In addition to moving in the front-to-rear direction of the vehicle, the fully open position also moves in the up-and-down direction of the vehicle. The distance between the second end portion at the fully closed position and the first end portion along the up-and-down direction of the vehicle is a first distance, and the distance between the second end portion at the fully open position and the first end portion along the up-and-down direction of the vehicle is a second distance larger than the first distance. The exterior component is constructed so that the relative rotation angle of two adjacent cylindrical components is less than a specified angle, and the specified angle is an angle that causes the exterior component to form a curved shape with the first distance as a diameter. When the sliding body is in the fully open position, the force-applying component forms a curved shape with the second distance as a diameter on the exterior component.

[0011] Effects of the Invention

[0012] In the wiring structure of the present invention, the outer casing is configured so that the angle at which two adjacent cylindrical parts rotate relative to each other is less than a predetermined angle, and the predetermined angle is an angle at which the outer casing forms a curved shape with a first distance as a diameter. According to the wiring structure of the present invention, a stable curved shape is formed when the radius of curvature R of the outer casing becomes smaller. Therefore, the wiring structure of the present invention has the effect of stabilizing the shape of the outer casing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] [Implementation Method]

Figure 6 Show Figure 7 VI-VI section.

[0037] 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.

[0038] The vehicle 100 has a sunroof 200 that opens and closes 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 that is configured to allow light to pass through.

[0039] 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.

[0040] 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 .

[0041] 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.

[0042] 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.

[0043] The wiring structure 1 of the present embodiment 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.

[0044] 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, 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 member 30.

[0045] The second fixing part 20 is a part fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may also be a protector for protecting the electric wire W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 20 has a space for laying the electric wire W and has a holding structure for holding the exterior member 30.

[0046] like Figure 3 As shown, the outer casing 30 of the present embodiment is formed by connecting a plurality of tubular components 6. The tubular components 6 are, for example, molded of insulating synthetic resin. Adjacent tubular components 6 are connected in a manner that allows relative rotation. A passage 6a into which the wire W and the force applying component 50 can be inserted is provided inside the tubular component 6.

[0047] like Figure 4 As shown, the cylindrical component 6 has a main body 60, a shaft portion 61, a through hole 62, a notch 63 and abutment portion 64. The main body 60 of this embodiment has a square cylindrical shape. A channel 6a is provided in the main body 60 that passes through along the axial direction Ax. The shaft portion 61 is arranged at one end of the axial direction Ax of the main body 60. The cylindrical component 6 has a pair of shaft portions 61. The pair of shaft portions 61 protrude from the main body 60 in opposite directions. The shape of the shaft portion 61 of the example is a cylindrical shape.

[0048] The through hole 62 is disposed at the other end of the main body 60 in the axial direction Ax. The tubular member 6 has a pair of through holes 62. The two tubular members 6 are connected by inserting the shaft 61 of one tubular member 6 into the through hole 62 of the other tubular member 6. The through hole 62 penetrates the wall portions 60b that face each other across the passage 6a.

[0049] The cutout 63 and the contact portion 64 limit the angle of relative rotation of the two cylindrical members 6 within a predetermined range. The cutout 63 is arranged near the shaft portion 61 in the main body 60. More specifically, one end of the main body 60 has a wall portion 60a in an arc shape. The shaft portion 61 is arranged coaxially with the arc shape of the wall portion 60a and protrudes from the wall portion 60a. The cutout 63 is formed by cutting off a portion of the edge of the wall portion 60a.

[0050] The abutment portion 64 is arranged near the through hole 62 in the main body 60. In more detail, the other end of the main body 60 has a wall portion 60b in an arc shape. The through hole 62 is arranged coaxially with the arc shape of the wall portion 60b. The abutment portion 64 can be a wall portion provided between the two wall portions 60b, or a column portion, or a protrusion. The abutment portion 64 is arranged to be located in the area formed by the cutout 63 when the shaft portion 61 is inserted into the through hole 62. In the case where the two cylindrical parts 6 rotate relative to each other, when the abutment portion 64 abuts against the end surface of the cutout 63, further rotation is restricted.

[0051] exist Figure 5 , the maximum angle θ when the two tubular components 6 rotate relative to each other is shown. The maximum angle θ is the angle at which the abutment portion 64 of one tubular component 6 abuts against the end surface of the cutout 63 of the other tubular component 6. The two tubular components 6 can rotate relative to each other within a range where the angle formed by the axial direction Ax1 of one tubular component 6 and the axial direction Ax2 of the other tubular component 6 does not exceed the maximum angle θ.

[0052] 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.

[0053] 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.

[0054] like Figure 4As shown, the outer component 30 is penetrated by the electric wire W and the force-applying member 50. The electric wire W is, for example, a sheathed electric wire having a twisted wire and a sheath. 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 arranged on the vehicle body 110. The electric wire W led out from the second end 30b is connected to a load arranged on the side of the sliding body 210. The load arranged on the sliding body 210 may be, for example, a lighting device, a dimming film of the glass arranged on the sliding body 210, or other electrical loads.

[0055] like Figure 1 and Figure 2 As shown, in the wiring structure 1 of the present embodiment, bent portions 33 and 34 bent in the vehicle front-rear direction X are formed between the first end portion 30 a and the second end portion 30 b of the exterior member 30 . 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.

[0056] 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.

[0057] 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.

[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] like Figure 6 and Figure 7As shown, the wire W and the force member 50 are inserted into the channel 6a of the cylindrical member 6. The force member 50 of the example is in the shape of a flat plate. In the force member 50, the cross-sectional shape perpendicular to the axial direction of the force member 50 is rectangular. The force member 50 extends from one end to the other end in the width direction H in the internal space of the outer member 30. The force member 50 is respectively opposite to the plurality of wires W in the vehicle up-down direction Y. In other words, the force member 50 has a width capable of supporting the plurality of wires W.

[0060] like Figure 7 As shown, the exterior member 30, the 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 bent in the vehicle front-rear direction X.

[0061] 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.

[0062] The pressing force F1 forms a first extension portion 31 in the exterior component 30. The pressing force F2 forms a second extension portion 32 in the exterior component 30. The second extension portion 32 is a portion extending along the surface 210a on the vehicle cabin side of the sliding body 210. The surface 210a on the vehicle cabin side is a surface facing the lower side Y2. When the surface 210a on the vehicle cabin side is a plane, the second extension portion 32 is formed in a straight line. When the surface 210a on the vehicle cabin side has a curved shape, the second extension portion 32 becomes a curved shape along the surface 210a on the vehicle cabin side.

[0063] In the wiring structure 1 of the present embodiment, as described below, the bent portion 33 in the fully closed position is formed by the exterior member 30 , and the bent portion 34 in the fully open position is formed by the urging member 50 .

[0064] First, the formation Figure 1 The structure of the curved portion 33 in the fully closed position shown in FIG. 1 is described below. In the outer casing 30 of the present embodiment, the maximum angle θ of the cylindrical member 6 is set to a predetermined angle θ1 in such a manner that the cylindrical members 6 connected to each other form the curved portion 33. Two adjacent cylindrical members 6 rotate relative to each other within a range below the predetermined angle θ1. The curved portion 33 is formed by rotating a plurality of consecutive cylindrical members 6 relative to each other at the predetermined angle θ1. Figure 1 The shape of the curved portion 33 shown determines the predetermined angle θ1.

[0065] The radius R1 of the curved portion 33 in the fully closed position is the minimum radius formed by the outer member 30 within the range allowed by the limiting structure 65 composed of the abutment portion 64 and the cutout 63. That is, in the curved portion 33 of the radius R1, the two adjacent cylindrical members 6 make the abutment portion 64 abut against the cutout 63. In this way, the outer member 30 of the present embodiment forms a curved shape with the first distance L1 as the diameter in a state where the relative rotation of the cylindrical member 6 is locked by the limiting structure 65. Therefore, when the sliding body 210 is in the fully closed position, each cylindrical member 6 of the outer member 30 forms a curved portion 33. At this time, the force application member 50 is elastically deformed into a shape corresponding to the shape of the outer member 30.

[0066] To form Figure 2 The structure of the curved portion 34 in the fully open position shown in FIG. Figure 2 In the fully open state shown in FIG. 1 , the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a second distance L2. The second distance L2 is greater than the first distance L1 in the fully closed state. In this case, the force applying member 50 forms a curved portion 34 of a radius R2 on the exterior member 30. Figure 7 As shown in FIG. 1 , the force applying member 50 of this embodiment has rigidity that enables the arc-shaped curved portion 54 to be formed in the fully opened state. The force applying member 50 in the fully opened state has an extension portion 52 extending along the sliding body 210 on the second end portion 30b side relative to the curved portion 54. That is, the force applying member 50 applies a pressing force F2 to the exterior member 30 through the extension portion 52 located on the second end portion 30b side relative to the curved portion 54. As a result, as shown in FIG. Figure 2 As shown, the second extension portion 32 extending along the sliding body 210 is formed on the exterior member 30 .

[0067] The force applying member 50 presses the exterior member 30 against the sliding body 210 by the pressing force F2, thereby suppressing the exterior member 30 from being separated from the sliding body 210. Therefore, the force applying member 50 can suppress the generation of abnormal noise caused by the vibration of the exterior member 30. In addition, when the sliding body 210 moves, the force applying member 50 can set the radius of the curved shape formed in the exterior member 30 to the maximum radius corresponding to the position of the sliding body 210. In other words, the force applying member 50 can maximize the curvature radius R of the wire W when the exterior member 30 slides relative to the sliding body 210 and the rail 220.

[0068] Furthermore, the urging member 50 presses the exterior member 30 against the sliding body 210 by the pressing force F2 when the sliding body 210 is fully closed. The pressing force F2 suppresses the exterior member 30 from separating from the sliding body 210. Therefore, the urging member 50 can suppress the generation of abnormal noise caused by vibration of the exterior member 30.

[0069] As described above, the wiring structure 1 of the present embodiment includes the first fixing portion 10, the second fixing portion 20, the outer member 30, the electric wire W, and the force 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 outer member 30 is formed by connecting a plurality of relatively rotatable cylindrical members 6. The outer 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. The electric wire W and the force member 50 are inserted through the outer member 30. The force member 50 presses the outer member 30 toward the sliding body 210.

[0070] The slider 210 moves in the vehicle vertical direction Y in addition to the vehicle front-rear direction X between the fully closed position in which the opening 120a is closed and the fully open position in which the opening 120a is opened. The distance between the second end 30b at the fully closed position and the first end 30a along the vehicle vertical direction Y is a first distance L1. The distance between the second end 30b at the fully open position and the first end 30a along the vehicle vertical direction Y is a second distance L2 that is larger than the first distance L1.

[0071] The outer casing 30 is configured so that the angle of relative rotation of two adjacent cylindrical members 6 is less than or equal to a predetermined angle θ1. The predetermined angle θ1 is an angle at which the outer casing 30 forms a curved shape with a first distance L1 as a diameter. When the slider 210 is in the fully open position, the biasing member 50 forms a curved shape with a second distance L2 as a diameter on the outer casing 30.

[0072] The wiring structure 1 of the present embodiment forms the curved shape of the exterior member 30 by the cylindrical member 6 when the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y becomes small when the wiring structure 1 of the present embodiment is fully closed. The cylindrical member 6 can stabilize the shape of the curved portion 33 when the curvature radius R of the exterior member 30 becomes small when the wiring structure 1 of the present embodiment is fully closed. When the sunroof 200 is fully opened, the biasing member 50 forms the curved portion 34 of the exterior member 30 and stabilizes the shape of the curved portion 34. Therefore, the wiring structure 1 of the present embodiment can stabilize the shape of the exterior member 30.

[0073] The urging member 50 of this embodiment presses the exterior member 30 toward the sliding body 210 in such a manner that the second extension portion 32 extending along the sliding body 210 is formed on the exterior member 30 when the sliding body 210 is in the fully opened position. Thus, the exterior member 30 is prevented from being separated from the sliding body 210, and the generation of abnormal noise caused by vibration of the exterior member 30 is prevented.

[0074] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
