Fig. 6 shows a cross section taken along line VI-VI in Fig. 7.
[0011] As shown in Fig. 1, a wiring structure 1 of the embodiment is applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, an automobile 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 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.
[0012] The vehicle 100 has a sunroof 200 that opens and closes the opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a member that slides along the vehicle front-rear direction X with respect to the opening 120a. The sliding body 210 of this embodiment is a plate-like member that closes or opens the opening 120a. The sliding body 210 may be glass that is configured to be able to transmit light.
[0013] The sunroof 200 has a mechanism such as a link mechanism that moves the sliding body 210 along a predetermined path, and a drive source such as a motor that operates the mechanism. The sunroof 200 moves the sliding body 210 between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. Figure 1 shows the sliding body 210 in the fully closed position. Figure 2 shows the sliding body 210 in the fully open position.
[0014] 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 that moves the slide body 210, and guides this mechanism in the vehicle front-rear direction X. The rail 220 further supports the exterior member 30 to form a first extension portion 31 in the exterior member 30.
[0015] The sunroof 200 of this embodiment moves the sliding body 210 along a path AR0 shown in Fig. 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 by the arrow AR1 in Fig. 2, the sliding body 210 moves toward the upper side Y1 in the vehicle up-down direction Y and toward the rear side X2 in the vehicle front-rear direction X.
[0016] Conversely, when the slide body 210 moves from the fully open position to the fully closed position, the slide body 210 moves toward the front side X1 in the vehicle longitudinal direction X and moves toward the lower side Y2 in the vehicle vertical direction Y.
[0017] The wiring structure 1 of the present embodiment has a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a biasing member 50. The exterior member 30 and the electric wire W configure a wire harness that is wired between the vehicle body 110 and the sliding body 210.
[0018] The first fixing part 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixing part 10 may be a protector that protects the electric wires W. The first fixing part 10 is molded, for example, from an insulating synthetic resin. The first fixing part 10 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.
[0019] The second fixing part 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may be a protector that protects the electric wires W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 20 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.
[0020] As shown in Fig. 3, the exterior member 30 of this embodiment is configured by connecting a plurality of cylindrical members 6. The cylindrical members 6 are molded, for example, from an insulating synthetic resin. Adjacent cylindrical members 6 are connected so as to be rotatable relative to each other. Inside the cylindrical members 6, a passage 6a is provided into which the electric wire W and the biasing member 50 can be inserted.
[0021] As shown in FIG. 4, the cylindrical member 6 has a main body 60, a shaft portion 61, a through hole 62, a notch 63, and an abutment portion 64. The main body 60 in this embodiment has a rectangular tube shape. The main body 60 is provided with a passage 6a penetrating along the axial direction Ax. The shaft portion 61 is disposed at one end of the main body 60 in the axial direction Ax. The cylindrical member 6 has a pair of shaft portions 61. The pair of shaft portions 61 protrude from the main body 60 in opposite directions. The illustrated shape of the shaft portion 61 is cylindrical.
[0022] 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 portion 61 of one tubular member 6 into the through hole 62 of the other tubular member 6. The through holes 62 penetrate the opposing wall portions 60b with the passage 6a in between.
[0023] The notch 63 and the abutment portion 64 restrict the angle of relative rotation of the two cylindrical members 6 within a predetermined range. The notch 63 is disposed in the vicinity of the shaft portion 61 of the main body 60. More specifically, one end of the main body 60 has an arc-shaped wall portion 60a. The shaft portion 61 is disposed coaxially with the arc-shaped wall portion 60a and protrudes from the wall portion 60a. The notch 63 is formed by cutting out a part of the edge of the wall portion 60a.
[0024] The abutment portion 64 is disposed near the through hole 62 in the main body 60. More specifically, the other end of the main body 60 has an arc-shaped wall portion 60b. The through hole 62 is disposed coaxially with the arc-shaped wall portion 60b. The abutment portion 64 may be a wall portion provided between the two wall portions 60b, a pillar portion, or a protrusion. The abutment portion 64 is disposed so as to be located in the area formed by the notch 63 when the shaft portion 61 is inserted into the through hole 62. When the two cylindrical members 6 rotate relative to each other, if the abutment portion 64 abuts against the end face of the notch 63, further rotation is restricted.
[0025] 5 shows the maximum angle θ when the two tubular members 6 rotate relative to each other. The maximum angle θ is the angle at which the abutment portion 64 of one tubular member 6 abuts against the end face of the notch 63 of the other tubular member 6. The two tubular members 6 are capable of relative rotation within a range in which the angle formed between the axial direction Ax1 of one tubular member 6 and the axial direction Ax2 of the other tubular member 6 does not exceed the maximum angle θ.
[0026] The exterior member 30 has a first end 30a held by the first fixing part 10 and a second end 30b held by the second fixing part 20. The first fixing part 10 holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 along the rail 220 in the vehicle front-rear direction X. The first fixing part 10 of the present embodiment holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 toward the front side X1.
[0027] The second fixing portion 20 holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 along the slide body 210 in the vehicle front-rear direction X. The second fixing portion 20 of the present embodiment holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.
[0028] As shown in FIG. 4, an electric wire W and a biasing member 50 are inserted into the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit body. The electric wire W drawn out from the first end portion 30a is connected to a power source or a control device arranged in the vehicle body 110. The electric wire W drawn out from the second end portion 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 light control film arranged on the glass of the sliding body 210, or other electric load.
[0029] As shown in Fig. 1 and Fig. 2, the wiring structure 1 of this embodiment forms curved portions 33, 34 that are curved in the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b of the exterior member 30. The curved portion 33 shown in Fig. 1 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully closed position. The curved portion 33 has a radius R1. The curved portion 34 shown in Fig. 2 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W on which the curved portions 33, 34 are formed has a U-shape or a J-shape.
[0030] 1, when the sliding body 210 is in the fully closed position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.
[0031] 2, when the sliding body 210 is in the fully open position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.
[0032] The second end 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.
[0033] As shown in Figs. 6 and 7, the electric wires W and the urging member 50 are inserted into the passage 6a of the cylindrical member 6. The urging member 50 shown in the example has a flat plate shape. In the urging member 50, a cross-sectional shape perpendicular to the axial direction of the urging member 50 is rectangular. The urging 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 urging member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the urging member 50 has a width capable of supporting the multiple electric wires W.
[0034] 7, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a curved U-shape or J-shape. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 in a state in which the biasing member 50 has a curved portion 54 that curves in the vehicle front-rear direction X.
[0035] The biasing member 50 bent to have the curved portion 54 applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the slide body 210. The pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.
[0036] The pressing force F1 forms a first extension portion 31 in the exterior member 30. The pressing force F2 forms a second extension portion 32 in the exterior member 30. The second extension portion 32 is a portion that extends along the cabin-side surface 210a of the sliding body 210. The cabin-side surface 210a is a surface that faces the lower side Y2. When the cabin-side surface 210a is a flat surface, the second extension portion 32 is formed in a straight line. When the cabin-side surface 210a has a curved shape, the second extension portion 32 has a curved shape that follows the cabin-side surface 210a.
[0037] In the wiring structure 1 of the present embodiment, as described below, the exterior member 30 forms a curved portion 33 in the fully closed position, and the biasing member 50 forms a curved portion 34 in the fully open position.
[0038] First, a configuration for forming the curved portion 33 in the fully closed position shown in Fig. 1 will be described. In the exterior member 30 of this embodiment, the maximum angle θ of the tubular members 6 is set to a predetermined angle θ1 so that the tubular members 6 connected to each other form the curved portion 33. Two adjacent tubular members 6 rotate relative to each other within a range equal to or less than the predetermined angle θ1. The predetermined angle θ1 is determined so that the curved portion 33 shown in Fig. 1 is formed by the relative rotation of each of the consecutive tubular members 6 at the predetermined angle θ1.
[0039] The radius R1 of the curved portion 33 in the fully closed position is the minimum radius formed by the exterior member 30 within the range permitted by the regulating structure 65 formed by the abutting portion 64 and the notch 63. That is, in the curved portion 33 of radius R1, the abutting portions 64 of two adjacent cylindrical members 6 abut against the notch 63. In this manner, the exterior member 30 of this embodiment forms a curved shape with a diameter of the first distance L1 in a state in which the relative rotation of the cylindrical members 6 is locked by the regulating structure 65. Therefore, when the sliding body 210 is in the fully closed position, each cylindrical member 6 of the exterior member 30 forms the curved portion 33. At this time, the biasing member 50 elastically deforms into a shape corresponding to the shape of the exterior member 30.
[0040] A configuration for forming the curved portion 34 in the fully open position shown in FIG. 2 will be described. In the fully open state shown in FIG. 2, the distance between the first end 30a and the second end 30b in the vehicle up-down 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 biasing member 50 forms the curved portion 34 of radius R2 in the exterior member 30. As shown in FIG. 7, the biasing member 50 of this embodiment has a rigidity capable of forming an arc-shaped curved portion 54 in the fully open state. The biasing member 50 in the fully open state has an extension portion 52 extending along the slide body 210 on the second end 30b side from the curved portion 54. That is, the biasing member 50 applies a pressing force F2 to the exterior member 30 by the extension portion 52 located on the second end 30b side from the curved portion 54. As a result, the second extension portion 32 extending along the slide body 210 is formed in the exterior member 30 as shown in FIG. 2.
[0041] The biasing member 50 presses the exterior member 30 against the sliding body 210 by the pressing force F2, and suppresses the exterior member 30 from being separated from the sliding body 210. Therefore, the biasing member 50 can suppress the generation of abnormal noise due to vibration of the exterior member 30. Furthermore, the biasing member 50 can set the radius of the curved shape formed in the exterior member 30 to a maximum radius according to the position of the sliding body 210 when the sliding body 210 moves. In other words, the biasing member 50 can maximize the bending R of the electric wire W when the exterior member 30 slides against the sliding body 210 and the rail 220.
[0042] Moreover, the biasing member 50 presses the exterior member 30 against the sliding body 210 by a pressing force F2 when the sliding body 210 is fully closed. The pressing force F2 prevents the exterior member 30 from separating from the sliding body 210. Therefore, the biasing member 50 can suppress the generation of abnormal noise due to vibration of the exterior member 30.
[0043] 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 biasing 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 with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 is configured by connecting a plurality of cylindrical members 6 that can rotate relatively. 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 electric wire W and the biasing member 50 are inserted into the exterior member 30. The biasing member 50 presses the exterior member 30 toward the sliding body 210.
[0044] The slide body 210 moves in the vehicle vertical direction Y in addition to the vehicle front-rear direction X between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. The distance in the vehicle vertical direction Y of the second end 30b relative to the first end 30a at the fully closed position is a first distance L1. The distance in the vehicle vertical direction Y of the second end 30b relative to the first end 30a at the fully open position is a second distance L2 that is larger than the first distance L1.
[0045] The exterior member 30 is configured so that the angle at which two adjacent cylindrical members 6 rotate relative to each other is equal to or smaller than a predetermined angle θ1. The predetermined angle θ1 is an angle at which the exterior member 30 forms a curved shape having a diameter equal to the first distance L1. The biasing member 50 forms a curved shape on the exterior member 30 having a diameter equal to the second distance L2 when the sliding body 210 is in the fully open position.
[0046] In the wiring structure 1 of this embodiment, when the exterior member 30 is fully closed and the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y becomes small, the cylindrical member 6 forms a curved shape of the exterior member 30. The cylindrical member 6 can stabilize the shape of the curved portion 33 when the exterior member 30 is fully closed and the bending R of the exterior member 30 becomes small. When the sunroof 200 is fully open, 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 this embodiment can stabilize the shape of the exterior member 30.
[0047] When the sliding body 210 is in the fully open position, the biasing member 50 of the present embodiment presses the exterior member 30 toward the sliding body 210 so as to form a second extending portion 32 extending along the sliding body 210 in the exterior member 30. This prevents the exterior member 30 from being separated from the sliding body 210, and suppresses the generation of abnormal noise due to vibration of the exterior member 30.
