[0011] As shown in Figures 1 to 3, the wiring structure 1 of this embodiment is a wiring structure for a sliding door and includes a protector 2, a rotating member 3, a shielding member 4, and an electric wire W. As shown in Figures 1 and 2, the electric wire W connects the vehicle body 110 and the sliding door 120 of the vehicle 100. The electric wire W is connected to a power source such as a battery and a control unit such as an ECU in the vehicle body 110.
[0012] The sliding door 120 slides along the first direction X with respect to the vehicle body 110. The first direction X is, for example, the longitudinal direction of the vehicle 100. The sliding door 120 opens and closes the opening of the vehicle 100 by moving to the front side X1 and the rear side X2. The sliding door 120 slides while being guided, for example, by rails arranged on the vehicle body 110. The sliding door 120 may slide by the operation of a link mechanism that connects the vehicle body 110 and the sliding door 120.
[0013] FIG. 1 is a diagram showing the wiring structure 1 when the sliding door 120 is in the fully closed position. When the sliding door 120 is in the fully closed position, as shown in FIG. 1, the electric wire W extends from the protector 2 in the first direction X. At this time, the rotating member 3 projects from the protector 2 along the first direction X. FIG. 2 is a diagram showing the wiring structure 1 when the sliding door 120 is in the fully open position. When the sliding door 120 is in the fully open position, as shown in FIG. 2, the electric wire W extends from the protector 2 in the second direction Y. The second direction Y is, for example, the vehicle width direction of the vehicle 100. When the sliding door 120 is in the fully open position, the rotating member 3 projects from the protector 2 toward the space 130 on the vehicle body 110 side. In other words, the rotating member 3 projects from the protector 2 along the second direction Y.
[0014] In the wiring structure 1 of the present embodiment, the rotation angle of the rotating member 3 when the sliding door 120 moves between the fully closed position and the fully open position is larger than 90°. As shown in FIG. 1, when the sliding door 120 is in the fully closed position, the rotating member 3 projects from the protector 2 toward the rear side X2. As shown in FIG. 2, when the sliding door 120 is in the fully open position, the rotating member 3 projects obliquely forward from the protector 2.
[0015] The protector 2 is arranged on the sliding door 120 and held by the sliding door 120. The rotating member 3 is rotatably supported by the protector 2. As shown in FIGS. 1 and 2, the rotating member 3 rotates following the change in the extending direction of the electric wire W due to the movement of the sliding door 120.
[0016] A cylindrical exterior member 5 may be disposed between the rotating member 3 and the vehicle body 110. In this case, the rotating member 3 holds one end portion 5a of the exterior member 5. The other end portion of the exterior member 5 is held by a holding member disposed on the vehicle body 110. The electric wire W is inserted through the exterior member 5 and protected by the exterior member 5. The exterior member 5 is a flexible member, for example, a member called a corrugated tube.
[0017] The shielding member 4 shown in FIG. 3 is a member that shields the electric wire W inside the protector 2 from the space 130 on the vehicle body 110 side. The shielding member 4 is stretchable and configured to stretch and contract while following the rotation of the rotating member 3.
[0018] As shown in FIG. 3, an opening 10 is formed between the protector 2 and the rotating member 3. The opening 10 is formed between the first side wall 61 of the protector 2 and the first side wall 81 of the rotating member 3. The opening 10 is open toward the vehicle body 110. When the shielding member 4 is not provided, the electric wire W routed inside the protector 2 may be visible from the vehicle body 110 side, which may affect the appearance of the wiring structure 1. For example, when fully closed as shown in FIG. 3, the opening width of the opening 10 is maximized, and the internal structure of the protector 2 becomes more visible to the passengers of the vehicle 100.
[0019] In the wiring structure 1 of the present embodiment, the stretchable shielding member 4 closes the opening 10 and covers the electric wire W from the vehicle body 110 side. Thereby, according to the wiring structure 1 of the present embodiment, the appearance when viewed from the vehicle body 110 side can be improved.
[0020] As shown in FIG. 4, the shielding member 4 has an expandable body 40, a first pin 41, and a second pin 42. The first pin 41 is held by the main body 6 of the protector 2. The second pin 42 is held by the main body 8 of the rotating member 3. The second pin 42 moves away from or approaches the first pin 41 in accordance with the rotation of the rotating member 3.
[0021] The telescopic body 40 has a first end 40a and a second end 40b in the direction of expansion and contraction. The telescopic body 40 is configured to expand and contract so that the length from the first end 40a to the second end 40b is changed. The first end 40a is connected to the first pin 41. The second end 40b is connected to the second pin 42. Therefore, the shielding member 4 can expand and contract the telescopic body 40 in accordance with the rotation of the rotating member 3.
[0022] The rotating member 3 rotates around the rotation axes 84 and 94 (see Figure 6) as indicated by the arrow AR1 in Figure 4. The first pin 41 and the second pin 42 are positioned to position the telescopic body 40 on side Y1 of the vehicle body 110 relative to the electric wires W inside the protector 2. The telescopic body 40 is also positioned so as not to interfere with the electric wires W when the rotating member 3 rotates.
[0023] As shown in Figure 5, the protector 2 has a body 6 and a cover 7. The body 6 and cover 7 are molded from, for example, an insulating synthetic resin. The cover 7 engages with the body 6 to form a cylindrical passage through which the electric wire W is routed.
[0024] The main body 6 has a groove-shaped cable routing path 60. The cable routing path 60 has a first side wall 61, a second side wall 62, and a bottom wall 63. The first side wall 61 and the second side wall 62 are erected from the widthwise ends of the bottom wall 63 and face each other in the widthwise direction of the bottom wall 63. The protector 2 is fixed to the sliding door 120 such that the cable routing path 60 extends in the first direction X and the first side wall 61 faces the vehicle body 110. In other words, the first side wall 61 is located on side Y1 of the vehicle body 110 relative to the second side wall 62.
[0025] The cable routing 60 has an inlet 60a and an outlet 60b. The inlet 60a is the end of the cable routing 60 on the side of the vehicle body 110. The inlet 60a opens facing the side Y1 of the vehicle body 110. The inlet 60a also opens toward the rear X2 so that the rotating member 3 can protrude toward the rear X2.
[0026] The exit section 60b is the end from which the electric wire W is pulled out toward the sliding door 120. The exit section 60b is open toward the upper side in the vehicle's vertical direction Z. That is, the electric wire W is routed inside the cable routing 60 in a curved shape. The electric wire W extends horizontally from the inlet section 60a and extends toward the upper side in the vehicle's vertical direction Z from the exit section 60b.
[0027] The bottom wall 63 has support holes 63a and 63b. The support hole 63a rotatably supports the rotating member 3. The support hole 63a is a recess that is recessed toward the lower side in the vehicle's vertical direction Z, or a through hole that penetrates the bottom wall 63. The support hole 63a is located at the entrance portion 60a.
[0028] The support hole 63b rotatably supports the first pin 41 of the shielding member 4. The support hole 63b is a recess that is recessed toward the lower side in the vertical direction Z of the vehicle, or a through hole that penetrates the bottom wall 63. In this embodiment, the support hole 63b is a through hole. The support hole 63b is located near the entrance portion 60a and near the first side wall 61. It is preferable that the support hole 63b is located in a position where it is hidden by the first side wall 61 when viewed from the second direction Y.
[0029] The cover 7 is a component that engages with the main body 6 to cover the cable routing 60 and form a cylindrical passage. The cover 7 has two support holes corresponding to support holes 63a and 63b. The support hole corresponding to support hole 63a rotatably supports the rotating member 3. The support hole corresponding to support hole 63b rotatably supports the first pin 41. In other words, the protector 2 rotatably supports both ends of the first pin 41.
[0030] As shown in Figure 4, the rotating member 3 is positioned at the inlet 60a of the protector 2. As shown in Figure 6, the rotating member 3 has a body 8 and a cover 9. The body 8 and cover 9 are molded from, for example, an insulating synthetic resin. The engagement of the cover 9 with the body 8 forms a cylindrical passage through which the electric wire W is inserted.
[0031] The main body 8 has a groove-shaped cable routing path 80. The cable routing path 80 has a first side wall 81, a second side wall 82, and a bottom wall 83. The first side wall 81 and the second side wall 82 are erected from the widthwise ends of the bottom wall 83 and face each other in the widthwise direction of the bottom wall 83. When the sliding door 120 is in the fully closed position, the first side wall 81 faces the vehicle body 110. That is, when the sliding door 120 is in the fully closed position, the first side wall 81 is located on the side of the vehicle body 110 relative to the second side wall 82.
[0032] The cable routing 80 has an inlet 80a and an outlet 80b. The inlet 80a is the end of the cable routing 80 on the vehicle body 110 side. The inlet 80a is provided with a rib for locking the end 5a of the exterior member 5. The outlet 80b is the end of the protector 2 from which the electric wire W is pulled out toward the cable routing 60. The rotating member 3 rotates relative to the protector 2 with the outlet 80b as its center.
[0033] The main body 8 has a rotating shaft 84. The rotating shaft 84 is inserted into a support hole 63a of the protector 2 and is rotatably supported by the support hole 63a. The rotating shaft 84 protrudes from the bottom wall 83 toward the side opposite the side walls 81 and 82.
[0034] The bottom wall 83 has a support hole 83a. The support hole 83a is a recess that is recessed toward the lower side in the vertical direction of the vehicle, or a through hole that penetrates the bottom wall 83. The support hole 83a rotatably supports the second pin 42 of the shielding member 4. The support hole 83a is located in the exit portion 80b and is situated near the first side wall 81. The support hole 83a may be positioned so as to be hidden by the first side wall 81 when viewed from the second direction Y.
[0035] The cover 9 is a member that engages with the main body 8 to cover the cable routing 80 and form a cylindrical passage. The cover 9 has a top wall 93 and a rotating shaft 94. The top wall 93 is a wall portion that faces the bottom wall 83 in the vehicle's vertical direction. The rotating shaft 94 protrudes from the top wall 93 toward the side opposite to the bottom wall 83. The rotating shaft 94 is rotatably supported by the cover 7 of the protector 2. The top wall 93 has a support hole corresponding to the support hole 83a. The support hole in the top wall 93 rotatably supports the second pin 42. In other words, the rotating member 3 rotatably supports both ends of the second pin 42.
[0036] As shown in Figure 7, the telescopic body 40 has a plurality of rod-shaped or plate-shaped shielding bodies 43 and a plurality of joints 44. The plurality of shielding bodies 43 form a screen that extends in the vertical direction Z of the vehicle. The shielding bodies 43 are made of, for example, synthetic resin or metal. The shielding bodies 43 are linear links and are capable of shielding the electric wires W.
[0037] The shielding body 43 may be made of a light-shielding material. However, the shielding body 43 may also be made of a light-transmitting material. The expandable body 40 formed by multiple shielding bodies 43 has an aesthetic appeal in itself. Therefore, the expandable body 40 that closes the opening 10 can improve the appearance of the cable routing structure 1. Also, having the expandable body 40 in front of the electric wire W makes it less likely for passengers to notice the electric wire W behind it. Therefore, the shielding member 4 can improve the appearance of the cable routing structure 1 compared to the case where there is no shielding member 4 between the electric wire W and the passenger.
[0038] Multiple shielding bodies 43 are connected by joints 44 so as to be rotatable relative to each other. The joints 44 connect the multiple shielding bodies 43 to each other so that the telescopic body 40 can extend and contract along the extension direction Ex. One shielding body 43 is connected to another shielding body 43 at both ends via joints 44.
[0039] The shielding member 4 has a fastener 45 that is fixed to the first pin 41. The fastener 45 is fixed to the tip of the first pin 41, which is inserted into the support hole 63b of the protector 2, and functions as a retainer.
[0040] Figure 8 shows the wiring structure 1 when the sliding door 120 is in a half-open state. In the half-open state, the opening width Wd of the opening 10 is narrower compared to the fully closed state in Figure 3. As shown in Figure 8, the shielding member 4 can close the opening 10 and cover the electric wires W inside the protector 2.
[0041] Figure 9 shows the inside of the protector 2 when the sliding door 120 is in a half-open position. The distance between the two pins 41 and 42 in the half-open position is narrower than the distance between the two pins 41 and 42 in the fully closed position shown in Figure 4. In other words, when the sliding door 120 moves from the fully closed position to the half-open position, the expandable body 40 of the shielding member 4 contracts. Conversely, when the sliding door 120 moves from the half-open position to the fully closed position, the expandable body 40 of the shielding member 4 extends.
[0042] Figure 10 shows the inside of the protector 2 when the sliding door 120 is fully open. The distance between the two pins 41 and 42 is narrowest when the door is fully open. In other words, the position of the second pin 42 on the rotating member 3 is the position where the second pin 42 is closest to the first pin 41 when the sliding door 120 is fully open. Thus, the wiring structure 1 of this embodiment is configured such that the second pin 42 is closest to the first pin 41 when the door is fully open, and the second pin 42 is furthest from the first pin 41 when the door is fully closed.
[0043] In the fully open position, the first side wall 81 of the rotating member 3 is close to the first side wall 61 of the protector 2. The gap between the two first side walls 61 and 81 is narrow, and the opening 10 is not effectively formed. In other words, when the sliding door 120 is in the fully open position, the opening width Wd of the opening 10 is minimized. Furthermore, the opening width Wd of the opening 10 increases as the sliding door 120 moves from the fully open position to the fully closed position.
[0044] Figure 11 shows the wiring structure 1 as seen from the side of the vehicle body 110 when the sliding door 120 is fully open. As shown in Figure 11, the rotating member 3 and the exterior member 5 cover the entrance portion 60a of the protector 2 from the vehicle body 110. In other words, when viewed from the side of the vehicle body 110, the inside of the protector 2 is not visible to the occupant.
[0045] Thus, the wiring structure 1 of this embodiment closes the opening 10 formed between the protector 2 and the rotating member 3 with the shielding member 4, making it difficult to see the electric wires W inside the protector 2. Furthermore, when the sliding door 120 is in the fully open position, the rotating member 3 covers the entrance portion 60a of the protector 2, making it difficult to see the electric wires W inside the protector 2. Therefore, the wiring structure 1 of this embodiment can improve the appearance when viewed from the side of the vehicle body 110.
[0046] As described above, the wiring structure 1 of this embodiment includes an electric wire W routed between the vehicle body 110 and the sliding door 120 of the vehicle 100, a protector 2, a rotating member 3, and a shielding member 4. The protector 2 is positioned on the sliding door 120 and has an entrance portion 60a facing the vehicle body 110 and an exit portion 60b through which the electric wire W is pulled out toward the sliding door 120. The rotating member 3 is a cylindrical member through which the electric wire W is inserted, positioned at the entrance portion 60a, and rotatably supported by the protector 2. The shielding member 4 closes the opening 10 that is created between the protector 2 and the rotating member 3 as the rotating member 3 rotates.
[0047] The shielding member 4 is configured to be expandable and contractible, with a plurality of rod-shaped or plate-shaped shielding bodies 43 connected to each other. The first end 40a in the expansion / contraction direction Ex of the shielding member 4 is held by the protector 2, and the second end 40b in the expansion / contraction direction Ex is held by the rotating member 3. The shielding member 4 expands and contracts in accordance with the rotation of the rotating member 3, closing the opening 10. In this embodiment, the wiring structure 1 makes it difficult to see the electric wires W inside the protector 2 from the vehicle body 110 side by closing the opening 10 with the shielding member 4.
[0048] In the wiring structure 1 of this embodiment, the opening width Wd of the opening 10 increases as the sliding door 120 moves from the fully open position to the fully closed position. The shielding member 4 is held by the rotating member 3 so as to extend when the sliding door 120 moves from the fully open position to the fully closed position. As the shielding member 4 extends in response to the increase in the opening width Wd of the opening 10, the electric wires W inside the protector 2 become less visible from the vehicle body 110 side.
[0049] The wiring structure 1 may be configured such that the opening width Wd increases as the sliding door 120 moves from the fully closed position to the fully open position. In this case, it is preferable that the shielding member 4 is held by the rotating member 3 so as it extends when the sliding door 120 moves from the fully closed position to the fully open position.
[0050] The configuration in which the protector 2 holds the shielding member 4 is not limited to the support hole 63b that holds the first pin 41. For example, the first side wall 61 of the protector 2 may have a configuration that holds the first end 40a of the shielding member 4. In this case, the first side wall 61 holds the first end 40a so that the expandable body 40 can expand and contract.
[0051] The configuration in which the rotating member 3 holds the shielding member 4 is not limited to the support hole 83a that holds the second pin 42. For example, the first side wall 81 of the rotating member 3 may have a configuration that holds the second end 40b of the shielding member 4. In this case, the first side wall 81 holds the second end 40b so that the expandable body 40 can expand and contract.
[0052] The contents disclosed in the above embodiments can be combined and implemented as appropriate. [Explanation of Symbols]
