Summary of the Invention

Problems to be Solved by the Invention

[0004] When the wiring structure between the vehicle body and the slide body has an exterior member, it is desirable that the shape of the exterior member is stable. The exterior member is held by the slide body and the vehicle body, for example, in a state having a curved portion curved in the sliding direction of the slide body. When the bending radius R of the curved portion changes according to the movement of the slide body, the shape of the exterior member may become unstable due to vibration or its own weight.

[0005] An object of the present invention is to provide a wiring structure capable of stabilizing the shape of an exterior member.

Furthermore, the components in the following embodiments include those that are easily conceivable by those skilled in the art or that are substantially identical.

Figure 3 shows the III-III cross-section of Figure 4.

[0011] As shown in Figure 1, the wiring structure 1 of the embodiment is applied to the 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 body 110. The body 110 has a roof 120 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.

[0012] Vehicle 100 has a sunroof 200 that opens and closes an opening 120a. The sunroof 200 has a slide body 210, rails 220, and a cable arrangement structure 1. The slide body 210 is a member that slides along the vehicle longitudinal direction X with respect to the opening 120a. In this embodiment, the slide body 210 is a plate-shaped member that closes the opening 120a or opens the opening 120a. The slide body 210 may be glass configured to allow light to pass through.

[0013] The sunroof 200 has a mechanism such as a link mechanism that moves the slide body 210 along a predetermined path, and a drive source such as a motor that operates the above mechanism. The sunroof 200 moves the slide body 210 between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. In FIG. 1, the slide body 210 in the fully closed position is shown. In FIG. 2, the slide body 210 in the fully open position is shown.

[0014] The rails 220 are fixed to the vehicle body 110. The rails 220 extend in the vehicle longitudinal direction X. The rails 220 support a mechanism that moves the slide body 210 and guides this mechanism in the vehicle longitudinal direction X. The rails 220 further support an exterior member 30 and form a first extending portion 31 on the exterior member 30.

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

[0016] Conversely, when the slide body 210 moves from the fully open position toward 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] As shown in Figures 1 to 3, the wiring structure 1 includes a first fixing part 10, a second fixing part 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 routed between the vehicle body 110 and the sliding body 210.

[0018] The first fixing part 10 is a component fixed to the vehicle body 110 of the vehicle 100. The first fixing part 10 may also be a protector that protects the electric wire W. The first fixing part 10 is molded from, for example, an insulating synthetic resin. The first fixing part 10 has a space through which the electric wire W is routed and a holding structure that holds the exterior member 30.

[0019] The second fixing part 20 is a component fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may also be a protector that protects the electric wires W. The second fixing part 20 is molded from, for example, an insulating synthetic resin. The second fixing part 20 has a space through which the electric wires W are routed and a holding structure that holds the exterior member 30.

[0020] The exterior member 30 is an elastically deformable cylindrical member. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded from, for example, an insulating synthetic resin. The exterior member 30 may have a bellows shape.

[0021] 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 so that the exterior member 30 extends from the first fixing portion 10 along the rail 220 in the vehicle longitudinal direction X. In this embodiment, the first fixing portion 10 holds the first end portion 30a so that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b of the exterior member 30 so that it extends from the second fixing portion 20 along the sliding body 210 in the vehicle longitudinal direction X. In this embodiment, the second fixing portion 20 holds the second end portion 30b of the exterior member 30 so that it extends from the second fixing portion 20 toward the front side X1.

[0023] The exterior member 30 is through which the electric wire W and the biasing member 50 are inserted. The electric wire W is, for example, a coated electric wire having stranded wire and insulation. The electric wire W may be a flat wiring material, a printed circuit board, or any other circuit board. The electric wire W drawn out from the first end 30a is connected to a power supply or control device located on the vehicle body 110. The electric wire W drawn out from the second end 30b is connected to a load located on the side of the slide body 210. The load located on the slide body 210 may be, for example, a lighting device, a dimming film placed on the glass of the slide body 210, or any other electrical load.

[0024] As shown in Figures 1 and 2, the exterior member 30 has curved portions 33 and 34 that curve in the vehicle longitudinal direction X between the first end 30a and the second end 30b. The curved portion 33 shown in Figure 1 is a curved portion formed on the exterior member 30 when the slide 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 on the exterior member 30 when the slide 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 and 34 are formed has a U-shape or a J-shape.

[0025] As shown in Figure 1, when the slide body 210 is in the fully closed position, the distance between the second end 30b and the first end 30a along the vehicle's vertical direction Y is the first distance L1. The radius R1 of the curved portion 33 is half the size of the first distance L1.

[0026] As shown in Figure 2, when the slide body 210 is in the fully open position, the distance between the second end 30b and the first end 30a along the vehicle's 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.

[0027] The second end portion 30b of the exterior member 30 moves together with the sliding body 210. At this time, the exterior member 30 follows the movement of the second fixing portion 20 while gradually changing the position in which the curved shape is formed.

[0028] The biasing member 50 in this embodiment has rigidity that allows it to press the exterior member 30 toward the slide body 210. The biasing member 50 is a rod-shaped or plate-shaped member and is elastically deformable. The biasing member 50 is made of metal or resin.

[0029] As shown in Figures 3 and 4, the cross-sectional shape of the exterior member 30 in this embodiment is rectangular. The illustrated biasing member 50 has a flat plate shape. In the biasing member 50, the cross-sectional shape perpendicular to the axial direction of the biasing member 50 is rectangular. The biasing member 50 extends from one end to the other in the width direction H within the internal space of the exterior member 30. The biasing member 50 faces each of the multiple electric wires W in the vehicle's vertical direction Y. In other words, the biasing member 50 has a width that can support multiple electric wires W.

[0030] The biasing member 50 in Figure 3 is positioned on the outside relative to the electric wire W. Therefore, in the curved sections 33 and 34, the biasing member 50 is located radially outward relative to the electric wire W. As shown in Figure 3, the biasing member 50 contacts the outer casing member 30 and applies pressing forces F1 and F2 to the outer casing member 30 at this contact surface.

[0031] As shown in Figure 4, the exterior member 30, the electric wire W, and the biasing member 50 are routed in a curved U-shape or J-shape. In other words, the biasing member 50 extends from the first fixing part 10 to the second fixing part 20 with a curved portion 54.

[0032] The biasing member 50, which is bent to have a curved portion 54, applies pressing forces F1 and F2 to the exterior member 30. Pressing force F1 is a force in the vehicle's vertical direction Y, which presses the exterior member 30 toward the rail 220. Pressing force F2 is a force in the vehicle's vertical direction Y, which presses the exterior member 30 toward the slide body 210. Pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.

[0033] A pressing force F1 forms a first extension portion 31 on the exterior member 30. A pressing force F2 forms a second extension portion 32 on the exterior member 30. As shown in Figure 2, the second extension portion 32 is the portion that extends along the passenger compartment side surface 210a of the slide body 210. The passenger compartment side surface 210a is the surface facing downward Y2. If the passenger compartment side surface 210a is flat, the second extension portion 32 is formed in a straight line. If the passenger compartment side surface 210a has a curved shape, the second extension portion 32 has a curved shape along the passenger compartment side surface 210a.

[0034] The biasing member 50 of this embodiment is configured to press the exterior member 30 toward the slide body 210 when the slide body 210 is in the fully closed position and when the slide body 210 is in the fully open position. In other words, the biasing member 50 has the rigidity to keep the exterior member 30 pressed toward the slide body 210 at all times. Therefore, the cable routing structure 1 of this embodiment can stabilize the shape of the exterior member 30. The biasing member 50 can keep the exterior member 30 in contact with the slide body 210 against external forces such as vibrations generated during driving.

[0035] The biasing member 50 may be positioned radially inward from the electric wire W in the curved portion. Figure 5 shows a biasing member 50 positioned inward from the electric wire W. The biasing member 50 located at the first extended portion 31 of the outer casing member 30 applies a pressing force F1 to the outer casing member 30 and the electric wire W. In other words, the pressing force F1 of the biasing member 50 is applied to the outer casing member 30 via the electric wire W. The biasing member 50 located at the second extended portion 32 of the outer casing member 30 applies a pressing force F2 to the outer casing member 30 and the electric wire W. In other words, the pressing force F2 of the biasing member 50 is applied to the outer casing member 30 via the electric wire W.

[0036] When the biasing member 50 is positioned inward relative to the electric wire W, a suitable bending radius (R) is formed on the biasing member 50, as described below. Figure 6 shows the biasing member 50 and the electric wire W as viewed from the width direction H. In Figure 6, the dashed line on the biasing member 50 indicates the curved shape when the biasing member 50 is bent on its own. If the biasing member 50 has high rigidity, the bending radius of the biasing member 50 becomes smaller when it is bent inside a narrow space Sp. In other words, the curved portion of the biasing member 50 tends to become tapered.

[0037] When the electric wire W is positioned outside the biasing member 50, the electric wire W supports the curved portion of the biasing member 50. The electric wire W allows the bending radius of the biasing member 50 to be larger compared to when the biasing member 50 bends on its own. Therefore, the bending durability of the biasing member 50 is improved.

[0038] The biasing member 50 may be positioned both inside and outside the electric wire W. Figure 7 shows biasing members 50 positioned on both sides of the electric wire W. The wiring structure 1 shown in Figure 7 has a first biasing member 50A and a second biasing member 50B. The first biasing member 50A is positioned inside the electric wire W. The second biasing member 50B is positioned outside the electric wire W. In other words, the electric wire W is sandwiched between the first biasing member 50A and the second biasing member 50B inside the outer sheathing member 30.

[0039] When the biasing members 50A and 50B are positioned on both sides of the electric wire W, the bending radius of the electric wire W is stabilized, as will be explained below. Figure 8 shows the shape of the electric wire W when one biasing member 50 is positioned on the outside of the electric wire W. As shown in Figure 8, when the electric wire W is positioned on the inside of the biasing member 50, the electric wire W may separate from the biasing member 50 due to its own weight, etc.

[0040] Figure 9 shows the shape of the electric wire W when one biasing member 50 is positioned inside the electric wire W. As shown in Figure 9, when the electric wire W is positioned outside the biasing member 50, tolerances may cause the electric wire W to separate from the biasing member 50. When the electric wire W separates from the biasing member 50, the bending radius of the electric wire W is likely to deviate from the target size.

[0041] By positioning the electric wire W between the two biasing members 50A and 50B, the bending radius of the electric wire W is controlled to the desired size. Furthermore, by generating a bending reaction force with the two biasing members 50A and 50B, it becomes possible to make the biasing members 50A and 50B thinner.

[0042] As described above, the cable routing structure 1 of this embodiment includes a first fixing part 10, a second fixing part 20, an exterior member 30, an electric wire W, and a biasing member 50. The first fixing part 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixing part 20 is fixed to the sliding body 210. The sliding body 210 moves along the vehicle's longitudinal direction X relative to an opening 120a provided in the roof 120 of the vehicle body 110. 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 electric wire W and the biasing member 50 are inserted through the exterior member 30.

[0043] The biasing member 50 forms curved portions 33 and 34 between the first end 30a and the second end 30b of the exterior member 30, which curve in the longitudinal direction X of the vehicle. In this embodiment, the cable routing structure 1 can stabilize the shape of the curved portions 33 and 34 with the biasing member 50.

[0044] In the curved portions 33 and 34 of the exterior member 30, the biasing member 50 may be positioned radially inward with respect to the electric wire W. In this case, the electric wire W supports the curved portion of the biasing member 50, and an appropriate bend radius can be formed in the biasing member 50.

[0045] The wiring structure 1 may have two biasing members 50A and 50B. In the curved portions 33 and 34 of the outer covering member 30, the first biasing member 50A is positioned radially inward with respect to the electric wire W, and the second biasing member 50B is positioned radially outward. With this configuration, the bending radius R of the electric wire W is controlled to the desired size.

[0046] In the curved portions 33 and 34 of the exterior member 30, the biasing member 50 may be positioned radially outward with respect to the electric wire W. In this case, the pressing forces F1 and F2 are transmitted from the biasing member 50 to the exterior member 30 without going through the electric wire W.

[0047] [Modified examples of embodiments] Modified examples of the embodiment will now be described. Figure 10 is a plan view of the biasing member according to the modified example of the embodiment, Figure 11 is a cross-sectional view of the biasing member according to the modified example of the embodiment, and Figure 12 is a diagram illustrating the bending radius of the biasing member. In the modified example of the embodiment, one difference from the above embodiment is that the biasing member 50 has a curved cross-sectional shape. Figure 11 shows the XI-XI cross-section of Figure 10.

[0048] As shown in Figure 10, the biasing member 50 is a plate-shaped member having an axial direction Ax. The axial direction Ax is the longitudinal direction of the biasing member 50. The biasing member 50 is, for example, a metal plate. As shown in Figure 11, the cross-sectional shape of the biasing member 50 perpendicular to the axial direction Ax is an arc shape. The cross-section of the biasing member 50 has an arc shape with radius r. In a biasing member 50 having a curved cross-sectional shape, the size of the bending R is determined according to the radius r of the cross-section.

[0049] As shown in Figure 12, when the biasing member 50 is bent on its own, a curved portion 53 is formed on the biasing member 50. The radius R0 of the curved portion 53 corresponds to the radius r of the cross section. When the radius r of the cross section is small, a curved portion 53 with a small value of radius R0 is formed on the biasing member 50, and when the radius r of the cross section is large, a curved portion 53 with a large value of radius R0 is formed on the biasing member 50. In other words, the value of the radius R0 of the curved portion 53 can be controlled by the radius r.

[0050] The radius r of the cross section is determined, for example, according to the distance Y in the vehicle vertical direction between the first end 30a and the second end 30b of the exterior member 30. The radius r of the cross section may also be determined in accordance with the second distance L2 in the fully open position shown in Figure 2. Figure 12 shows a biasing member 50 folded back to form an arc-shaped curved portion 53. The value of the radius r of the cross section is set, for example, so that when the biasing member 50 is folded back as shown in Figure 12, the biasing member 50 forms a curved shape with the second distance L2 as its diameter. In other words, the design value of the radius r of the cross section is determined so that the following equation (1) is realized. R0 = R2 = L2 / 2 (1)

[0051] As described above, when the radius r of the cross-section is determined, a curved portion 34 with radius R2 is formed in the exterior member 30 when fully open, as shown in Figure 2. The size of radius R2 at this time is determined by the radius r of the cross-section of the biasing member 50.

[0052] When the sliding body 210 is in the fully closed position, a curved portion 33 is formed in the exterior member 30 as shown in Figure 1. The radius R1 of the curved portion 33 is smaller than the size determined by the radius r of the cross-section. The radius R1 of the curved portion 33 is determined by the first distance L1. That is, when the distance L between the first end 30a and the second end 30b is smaller than the second distance L2, the biasing member 50 forms a bend R corresponding to the distance L. In this way, the biasing member 50 can make the bend R of the exterior member 30 the maximum size corresponding to the distance L when the sunroof 200 is fully closed, fully open, and open / closed. In the modified sunroof 200, the sliding body 210 is moved such that the second distance L2 is greater than the first distance L1, similar to the sunroof 200 of the above embodiment.

[0053] The radius r of the cross section may be determined, for example, in correspondence with the first distance L1 in the fully closed position shown in Figure 1. In this case, the value of the radius r of the cross section is set such that, for example, when the biasing member 50 is folded back as shown in Figure 12, the biasing member 50 forms a curved shape with the first distance L1 as its diameter. In other words, the design value of the radius r of the cross section is determined so as to satisfy the following equation (2). R0 = R1 = L1 / 2 (2)

[0054] As described above, when the radius r of the cross-section is determined, a curved portion 34 with radius R1 is formed on the exterior member 30 when fully open, as shown in Figure 13. The size of the radius R1 of the curved portion 34 is determined by the radius r of the cross-section of the biasing member 50. When the slide body 210 is in the fully open position, an inclined portion 35 is formed on the exterior member 30. The inclined portion 35 is the part that extends from the curved portion 34 to the second fixing portion 20 and is inclined with respect to the vehicle's longitudinal direction X.

[0055] Furthermore, when the slide body 210 is in the fully closed position, a curved portion 33 with radius R1 is formed on the exterior member 30, as shown in Figure 1. The size of the radius R1 of the curved portion 33 is determined by the radius r of the cross-section.

[0056] When the radius r of the cross-section is determined to realize equation (2), the wire harness can be made as short as possible. That is, the electric wire W, the outer sheathing member 30, and the biasing member 50 can be made as short as possible.

[0057] It should be noted that the actual value of the cross-sectional radius r may not match the theoretical value that realizes equations (1) and (2) above. For example, in the biasing member 50, the cross-sectional radius r may deviate slightly from the theoretical value due to manufacturing tolerances, etc. In this case, the radii of the formed curved portions 33 and 34 may deviate from the target radii R1 and R2. In other words, the diameters of the curved portions 33 and 34 may deviate from the first distance L1 and the second distance L2.

[0058] Even if the actual cross-sectional radius r matches the theoretical value, the radii of the formed curved portions 33 and 34 may differ from the target radii R1 and R2. In other words, when the biasing member 50 is folded back, the radii of the actually formed curved portions 33 and 34 may deviate from the target size.

[0059] Furthermore, the biasing member 50 may have different cross-sectional radii r at different positions in the axial direction Ax. For example, the biasing member 50 may be provided with a first part that forms the curved portion 33 when fully closed and a second part that forms the curved portion 34 when fully open. In this case, the cross-sectional radius r of the first part may be a value that satisfies equation (2). The cross-sectional radius r of the second part may be a value that satisfies equation (1).

[0060] As described above, the slide body 210 of this embodiment moves in the vehicle vertical direction Y in addition to the vehicle longitudinal direction X between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. The distance of the second end 30b relative to the first end 30a along the vehicle vertical direction Y in the fully closed position is the first distance L1. The distance of the second end 30b relative to the first end 30a along the vehicle vertical direction Y in the fully open position is the second distance L2, which is different from the first distance L1.

[0061] The biasing member 50 is configured to form a curved portion with a first distance L1 as its diameter, or to form a curved portion with a second distance L2 as its diameter. The biasing member 50 may be configured to form both a curved portion 33 with a first distance L1 as its diameter and a curved portion 34 with a second distance L2 as its diameter.

[0062] The biasing member 50 shown in the example is a plate-shaped member. The cross-sectional shape of the biasing member 50 perpendicular to the axial direction Ax of the biasing member 50 is an arc shape. The value of the radius r of the arc shape is determined such that when the biasing member 50 is folded back, the biasing member 50 forms a curved shape with a diameter of a first distance L1, or so that when the biasing member 50 is folded back, the biasing member 50 forms a curved shape with a diameter of a second distance L2.

[0063] When the value of radius r used is such that the biasing member 50 forms a curved shape with a diameter equal to the first distance L1, it is possible to minimize the length of the outer casing member 30 and the electric wire W. When the value of radius r used is such that the biasing member 50 forms a curved shape with a diameter equal to the second distance L2, the bending radius R of the outer casing member 30 can be set to the maximum size corresponding to the distance L.

[0064] The means for forming a curved portion of a predetermined radius in the biasing member 50 is not limited to the value of the radius r of the cross-section. For example, the biasing member 50 may have a main body and a restricting portion that restricts the shape of the curved portion formed in the main body. As an example, the restricting portion of the biasing member 50 may be made of a superelastic alloy. In this case, the main body of the biasing member 50 may have a restricting portion that gives a curved shape of radius R1 to the portion that forms the curved portion 33. The main body of the biasing member 50 may have a restricting portion that gives a curved shape of radius R2 to the portion that forms the curved portion 34. The main body of the biasing member 50 can generate a repulsive force in the vertical direction Y of the vehicle while its curved shape is restricted by the restricting portion.

[0065] The embodiments and modifications disclosed above can be combined and implemented as appropriate. [Explanation of Symbols]
