[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-151906 Summary of the Invention [Problem to be solved by the invention]

[0004] When the wiring structure between the car body and the sliding body has an exterior member, it is desirable that the shape of the exterior member is stable. The exterior member is held by the sliding body and the car body, for example, with a curved portion that curves toward the sliding direction of the sliding body. When the width of the space in which the exterior member is housed is narrow, the radius of the curved portion of the exterior member becomes small. If the shape of the curved portion is not stable, it may affect the bending durability of the electric wires routed inside the exterior member.

[0005] An object of the present invention is to provide a wiring structure that can stabilize the shape of an exterior member. [Means for solving the problem]

[Effects of the Invention]

[0007] In the wiring structure according to the present invention, the exterior member is configured so that the angle at which two adjacent tubular members rotate relative to each other is equal to or less than a predetermined angle, and the predetermined angle is an angle at which the exterior member forms a curved shape with a diameter equal to the first distance. According to the wiring structure according to the present invention, a stable curved shape is formed when the bending radius R of the exterior member becomes small. Therefore, the wiring structure according to the present invention has the effect of stabilizing the shape of the exterior member. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a wiring structure according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Figs. 1 to 7. This embodiment relates to a wiring structure. Figs. 1 and 2 are side views of the wiring structure according to the embodiment, Fig. 3 is a side view of an exterior member according to the embodiment, Fig. 4 is a view of a tubular member according to the embodiment, Fig. 5 is a view explaining the maximum angle when two tubular members rotate relative to each other, Fig. 6 is a cross-sectional view of the wiring structure according to the embodiment, and Fig. 7 is a side view of the wiring structure according to the embodiment. Fig. 6 shows a cross section taken along line VI-VI in Fig. 7.

[0011] As shown in FIG. 1, the 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 slider 210, a rail 220, and a wiring structure 1. The slider 210 is a member that slides relative to the opening 120a along the vehicle longitudinal direction X. In this embodiment, the slider 210 is a plate-like member that closes or opens the opening 120a. The slider 210 may be glass that is configured to allow light to pass through.

[0013] The sunroof 200 has a mechanism such as a link mechanism that moves the slider 210 along a predetermined path, and a drive source such as a motor that operates the mechanism. The sunroof 200 moves the slider 210 between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. Figure 1 shows the slider 210 in the fully closed position. Figure 2 shows the slider 210 in the fully open position.

[0014] 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 that moves the slider 210 and guides this mechanism in the vehicle longitudinal direction X. The rail 220 further supports the exterior member 30 and forms a first extending portion 31 in the exterior member 30.

[0015] The sunroof 200 of this embodiment moves the slider 210 along a path AR0 shown in Fig. 2. The movement of the slider 210 along the path AR0 includes movement along the vehicle longitudinal direction X and movement along the vehicle vertical direction Y. When the slider 210 moves from the fully closed position to the fully open position, as shown by arrow AR1 in Fig. 2, the slider 210 moves toward an upper side Y1 in the vehicle longitudinal direction Y and toward a rear side X2 in the vehicle longitudinal direction X.

[0016] Conversely, 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 longitudinal direction X and toward the lower side Y2 in the vehicle vertical direction Y.

[0017] The wiring structure 1 of this 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 constitute 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 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 from, for example, 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 portion 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing portion 20 may be a protector that protects the electric wires W. The second fixing portion 20 is molded from, for example, an insulating synthetic resin. The second fixing portion 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 formed 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. A passage 6a is provided inside the cylindrical members 6, into which the electric wires W and the biasing member 50 can be inserted.

[0021] As shown in FIG. 4, the tubular 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 cylindrical shape. The main body 60 is provided with a passage 6a that penetrates 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 tubular member 6 has a pair of shaft portions 61. The pair of shaft portions 61 protrude in opposite directions from the main body 60. 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 cylindrical member 6 has a pair of through holes 62. The two cylindrical members 6 are connected by inserting the shaft portion 61 of one cylindrical member 6 into the through hole 62 of the other cylindrical member 6. The through holes 62 penetrate through wall portions 60b that face each other 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 near 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 portion 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 cylindrical members 6 rotate relative to each other. The maximum angle θ is the angle at which the abutment portion 64 of one cylindrical member 6 abuts against the end face of the notch 63 of the other cylindrical member 6. The two cylindrical members 6 are capable of relative rotation within a range in which the angle formed between the axial direction Ax1 of one cylindrical member 6 and the axial direction Ax2 of the other cylindrical member 6 does not exceed the maximum angle θ.

[0026] The exterior member 30 has a first end 30a held by the first fixing portion 10 and a second end 30b held by the second fixing portion 20. The first fixing portion 10 holds the first end 30a so 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 30a so that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0027] 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 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 so 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 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 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 Figures 1 and 2, the wiring structure 1 of this embodiment forms curved portions 33, 34 that curve in the vehicle longitudinal direction X between the first end 30a and the second end 30b of the exterior member 30. The curved portion 33 shown in Figure 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 Figure 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 having the curved portions 33, 34 formed thereon has a U-shape or a J-shape.

[0030] 1, when the slider 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 slider 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 tubular member 6. The illustrated urging member 50 has a flat plate shape. The cross-sectional shape of the urging member 50, 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 that can support the multiple electric wires W.

[0034] 7, the exterior member 30, the electric wires W, and the biasing member 50 are arranged in a U-shaped or J-shaped curve. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 in a state where it 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's up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle's up-down direction Y, and presses the exterior member 30 toward the slider 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 flat, 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 this embodiment, as will be described below, the exterior member 30 forms the curved portion 33 in the fully closed position, and the biasing member 50 forms the 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 multiple 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 smallest radius formed by the exterior member 30 within the range allowed by the restriction structure 65 formed by the abutment portions 64 and the notches 63. That is, in the curved portion 33 of radius R1, two adjacent tubular members 6 abut the abutment portions 64 against the notches 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 tubular members 6 is locked by the restriction structure 65. Therefore, when the sliding body 210 is in the fully closed position, each tubular 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] The 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 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 biasing member 50 forms the curved portion 34 with a radius R2 in the exterior member 30. As shown in FIG. 7, the biasing member 50 of this embodiment has sufficient rigidity to form the arc-shaped curved portion 54 in the fully open state. In the fully open state, the biasing member 50 has an extending portion 52 extending along the sliding body 210 on the second end 30b side of the curved portion 54. In other words, the biasing member 50 applies a pressing force F2 to the exterior member 30 by the extending portion 52 located on the second end 30b side of the curved portion 54. As a result, the second extending portion 32 extending along the sliding 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 with the pressing force F2, and 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. Furthermore, the biasing member 50 can maximize the radius of the curved shape formed in the exterior member 30 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 wires W when the exterior member 30 slides relative to the sliding body 210 and the rail 220.

[0042] Furthermore, the biasing member 50 presses the exterior member 30 against the sliding body 210 with 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 prevent the occurrence of abnormal noise due to vibration of the exterior member 30.

[0043] As described above, the wiring structure 1 of this embodiment includes the first fixed portion 10, the second fixed portion 20, the exterior member 30, the electric wire W, and the biasing member 50. The first fixed portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixed portion 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle longitudinal direction X with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 is formed by connecting multiple tubular members 6 that are rotatable relative to each other. The exterior member 30 has a first end portion 30a held by the first fixed portion 10 and a second end portion 30b held by the second fixed portion 20. The electric wire W and the biasing member 50 are inserted through the exterior member 30. The biasing member 50 presses the exterior member 30 toward the sliding body 210.

[0044] The slider 210 moves in the vehicle vertical direction Y as well as in the vehicle fore-and-aft direction X between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is open. The distance between the first end 30a and the second end 30b in the vehicle vertical direction Y at the fully closed position is a first distance L1. The distance between the first end 30a and the second end 30b in the vehicle vertical direction Y at the fully open position is a second distance L2 that is greater 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 whose diameter is the first distance L1. The biasing member 50 causes the exterior member 30 to form a curved shape whose diameter is the second distance L2 when the sliding body 210 is in the fully open position.

[0046] In the wiring structure 1 of this embodiment, the tubular member 6 forms the curved shape of the exterior member 30 when the sunroof 200 is fully closed, when the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is small. The tubular member 6 can stabilize the shape of the curved portion 33 when the exterior member 30 is fully closed, when the bending radius R of the exterior member 30 is small. When the sunroof 200 is fully open, the biasing member 50 forms the curved portion 34 of the exterior member 30, stabilizing 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 extension portion 32 extending along the sliding body 210 in the exterior member 30. This prevents the exterior member 30 from separating from the sliding body 210, and suppresses the generation of abnormal noise due to vibration of the exterior member 30.

[0048] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
