[0009] <Embodiment> Hereinafter, a power supply device according to an embodiment of the present invention will be described with reference to the drawings. The power supply device 1 according to this embodiment is provided between a vehicle body BD and a sliding door DR of a vehicle. With this arrangement, the power supply device 1 can supply power from the vehicle body BD side to the sliding door DR side.

[0010] (Configuration of power supply device) 1, a power supply device 1 of this embodiment includes a first protector 2, a second protector 3, and a wiring member 4. The second protector 3 is provided rotatably about a rotation axis AX relative to the first protector 2. The wiring member 4 extends to pass through the first protector 2 and the second protector 3. In this embodiment, the wiring member 4 is a harness including electric wires for supplying power from a power source.

[0011] The first protector 2 and the second protector 3 are provided, for example, on the vehicle body BD side of the vehicle body BD and the sliding door DR. The first protector 2 is fixed to the vehicle body BD. The wiring member 4 extends from the vehicle body BD to the sliding door DR via the first protector 2 and the second protector 3.

[0012] Hereinafter, the direction in which the rotation axis AX extends is referred to as the Z direction, and the directions intersecting each other in a plane facing the Z direction are referred to as the X direction and the Y direction. For example, the X direction, the Y direction, and the Z direction may be perpendicular to each other. Hereinafter, the X direction is also referred to as the "first direction," and the Y direction is also referred to as the "second direction." Hereinafter, the +X direction of the X direction is also referred to as the "one side of the first direction," and the -X direction of the X direction is also referred to as the "other side of the first direction." Hereinafter, the +Y direction of the Y direction is also referred to as the "one side of the second direction," and the -Y direction of the Y direction is also referred to as the "other side of the second direction."

[0013] The second protector 3 is supported by the first protector 2. The second protector 3 can rotate between an extended position P1 and a bent position P2. The extended position P1 is a position where the wiring member 4 extends within the second protector 3 as shown by a solid line in FIG. 1. For example, the extended position P1 is a position when the sliding door DR is closed relative to the vehicle body BD. On the other hand, the bent position P2 is a position where the wiring member 4 is bent within the second protector 3 as shown by a two-dot chain line in FIG. 1. For example, the bent position P2 is a position when the sliding door DR is opened relative to the vehicle body BD. The first protector 2 and the second protector 3 protect the outer periphery of the wiring member 4 passing through the first protector 2 and the second protector 3 from the extended position P1 to the bent position P2.

[0014] (Configuration of the First Protector) The first protector 2 has a first opening 2a and a second opening 2b. The first opening 2a is provided at an end of the first protector 2 on the +X direction side. The first opening 2a opens on the +X direction side. On the other hand, the second opening 2b is provided at an end of the first protector 2 on the -X direction side. The second opening 2b opens from the -X direction side to the +Y direction side. In this embodiment, the first opening 2a faces a portion of the second opening 2b that opens on the -X direction side, and opens on the +X direction side on the +X direction side. The wiring member 4 passes through the first protector 2 via the first opening 2a and the second opening 2b.

[0015] As shown in FIG. 2, the first protector 2 includes a first base 21 and a first lid 22.

[0016] The first base 21 has a bottom 211 and a pair of first side walls 212. The bottom 211 is a wall extending in the X and Y directions. The bottom 211 has a first bearing 21c recessed about the rotation axis AX. The pair of first side walls 212 extend from both ends of the bottom 211 to the first lid 22 so as to face each other, sandwiching both sides of the passage space of the routing member 4. For example, the rotation axis AX may be shifted in the +Y direction from the center of the Y direction of the first protector 2 with respect to the position in the X direction where the rotation axis AX exists.

[0017] The first lid 22 closes a portion of the first base 21 that is open in the Z direction. The first lid 22, together with the first base 21, defines a passage space for the routing member 4. The routing member 4 passes through the passage space defined by combining the first base 21 and the first lid 22. The first lid 22 has a second bearing portion 22c that is recessed opposite the first bearing portion 21c around the rotation axis AX.

[0018] (Configuration of the second protector) 3, the second protector 3 has a base end opening 3a and a tip end opening 3b. The base end opening 3a and the tip end opening 3b are open to face each other in the direction in which the wiring member 4 passes through the second protector 3. The wiring member 4 passes through the second protector 3 via the base end opening 3a and the tip end opening 3b.

[0019] In this embodiment, the tip opening 3b is open in the extension direction of the routing member 4. On the other hand, the base end opening 3a is open in a plurality of directions so that the routing member 4 passes through at the extension position P1 and also passes through at the bent position P2. For example, the base end opening 3a is open over an angle range of 60° or more (even more, an angle range of 90° or more) around the rotation axis AX.

[0020] The second protector 3 includes a second base 31 and a second lid 32. The second base 31 closes a portion of the second lid 32 that opens in the Z direction. The second base 31, together with the second lid 32, defines a passage space for the wiring member 4. An end portion of the second base 31 adjacent to the base end opening 3a (an end portion defining the base end opening 3a) is formed in an arc shape over the angle range in which the base end opening 3a is provided. The wiring member 4 passes through the passage space defined by combining the second base 31 and the second lid 32.

[0021] The second base portion 31 has a first shaft portion 31a. The first shaft portion 31a is a protruding portion centered on the rotation axis line AX. The first shaft portion 31a protrudes toward the outside of the second protector 3, that is, in the Z direction.

[0022] The second cover 32 has a top surface portion 321 and a pair of second side walls 322. The top surface portion 321 has a second shaft portion 32a. The second shaft portion 32a is a protruding portion centered on the rotation axis line AX. The second shaft portion 32a protrudes toward the outside of the second protector 3, in the opposite direction to the first shaft portion 31a. The first shaft portion 31a is rotatably fitted into the first bearing portion 21c. The second shaft portion 32a is rotatably fitted into the second bearing portion 22c. Due to this support structure, the second protector 3 is rotatable around the rotation axis line AX relative to the first protector 2.

[0023] The pair of second side wall portions 322 extend from both ends of the top surface portion 321 to the second base portion 31 so as to face each other, sandwiching both sides of the passage of the wiring member 4 therebetween.

[0024] As shown in FIG. 1, the second protector 3 is provided in the first protector 2 so that a part of the second protector 3 protrudes to the outside of the first protector 2 through the second opening 2b at the extended position P1 and the bent position P2. For example, the second protector 3 is provided in the first protector 2 so that the tip opening 3b protrudes to the -X direction side of the second opening 2b at the extended position P1. On the other hand, the second protector 3 is provided in the first protector 2 so that the tip opening 3b protrudes to the +Y direction side of the second opening 2b at the bent position P2. Here, the tip opening 3b faces the -X direction at the extended position P1. The direction in which the tip opening 3b faces rotates from the -X direction through the +Y direction to a direction slightly inclined toward the +X direction from the +Y direction as the second protector 3 rotates from the extended position P1 to the bent position P2. In this embodiment, the rotation range of the second protector 3 exceeds 90°.

[0025] 4 and 5, the second protector 3 has an outer surface 3s on the -Y direction side at the extending position P1 of the second protector 3. The outer surface 3s faces outward with its back to the rotation axis AX. The outer surface 3s is connected to the base end opening 3a. The outer surface 3s is formed, for example, between the base end opening 3a and a distal end tube portion 3t described later.

[0026] In this embodiment, the outer surface 3s has a shape that conforms to the routing member 4 passing through the second protector 3 at the stretched position P1. The "shape that conforms to the routing member" includes not only the case where the shape is completely the same as the routing member 4, but also the case where the shape is slightly curved or inclined with respect to the shape of the routing member 4. The "case where the shape is slightly curved or inclined" means that, when viewed at the stretched position P1, in the region where the outer surface 3s exists in the second protector 3, the variation in the distance in the Y direction between the outer surface 3s and the routing member 4 is less than half the width of the routing member 4. Here, the width of the routing member 4 is the width in the Y direction at the stretched position P1.

[0027] In this embodiment, the outer surface 3s is flat and parallel to the rotation axis AX. The term "flat" refers not only to a completely flat surface, but also to a surface with a slight curvature or step. The term "a surface with a slight curvature or step" means that, when viewed from the extended position P1, in a region of the second protector 3 where the outer surface 3s exists, the positional variation of the outer surface 3s in the Y direction is equal to or less than the plate thickness of the second side wall portion 322 in the Y direction.

[0028] Here, the plane formed by the outer side surface 3s is a plane extending in the X direction when the second protector 3 is at the extended position P1. The plane formed by the outer side surface 3s refers to the plane formed closest to the -Y direction among the side surfaces on the -Y direction side of the second protector 3 at the extended position P1. For example, the width in the X direction of the plane formed by the outer side surface 3s may be half or more of the shortest distance between the rotation axis AX and the outer side surface 3s.

[0029] When the second protector 3 is in the extended position P1, the outer surface 3s is provided on the second side wall portion 322 located on the -Y direction side of the pair of second side wall portions 322. In this arrangement, the outer surface 3s is provided facing the -Y direction at a position aligned in the -Y direction of the rotation axis AX with the routing member 4 in between. Note that the inner surface exposed to the passage space inside the second protector 3 located on the back side of the outer surface 3s has a plane parallel to the outer surface 3s.

[0030] The second protector 3 has a cylindrical tip tube portion 3t. When the second protector 3 is in the extended position P1, the tip tube portion 3t extends in the X direction. A tip opening 3b is formed in the tip tube portion 3t. As shown in FIG. 4, when the second protector 3 is in the extended position P1, the central axis AC of the tip tube portion 3t is located on the -Y direction side of the rotation axis AX. On the other hand, the central axis AC of the tip tube portion 3t is shifted on the -Y direction side from the rotation axis AX to such an extent that it does not contact the first side wall portion 212 of the first protector 2 even when the second protector 3 rotates. For example, the central axis AC of the tip tube portion 3t may coincide with the central axis of the wiring member 4 in the tip tube portion 3t.

[0031] 6 and 7, the second protector 3 has an inner surface 3q on the +X direction side at the bending position P2 of the second protector 3. The inner surface 3q is connected to the base end opening 3a. The inner surface 3q is formed, for example, between the base end opening 3a and the tip tube portion 3t.

[0032] In this embodiment, the inner surface 3q faces the rotation axis AX across the wiring member 4. The inner surface 3q has a curved shape that follows the bending posture of the wiring member 4 passing through the second protector 3 at the bending position P2. The shape that follows the bending posture of the wiring member 4 includes not only the case where the shape completely matches the shape of the wiring member 4 in the bending posture, but also the case where the curvature is slightly different from the shape of the wiring member 4. "The case where the curvature is slightly different from the shape of the wiring member" means that, when viewed at the bending position P2, in the region where the inner surface 3q exists in the second protector 3, the variation in the distance between the inner surface 3q and the wiring member 4 is less than half the width of the wiring member 4. Here, the width of the wiring member 4 is the width in the Y direction at the extension position P1.

[0033] In this embodiment, the inner surface 3q is curved toward the +Y direction as it moves toward the -X direction when the second protector 3 is at the bending position P2. Here, the curved surface formed by the inner surface 3q refers to the curved surface formed closest to the rotation axis AX among the side surfaces of the second protector 3 on the -Y direction side at the bending position P2. The outer surface exposed to the outside of the second protector 3 located on the back side of the inner surface 3q of the second side wall portion 322 has a curved shape with the same curvature as the inner surface 3q, or a curved shape with a slightly different curvature. The "cross-sectional shape with a slightly different curvature" means that in the region where the inner surface 3q exists in the second protector 3, the variation in the distance between the inner surface 3q and the outer surface located on the back side of the inner surface 3q is equal to or less than the plate thickness of the second side wall portion 322. Here, the plate thickness of the second side wall portion 322 is the plate thickness in the Y direction at the extension position P1.

[0034] When the second protector 3 is in the bent position P2, the inner surface 3q is provided on the second side wall portion 322 located on the +X direction side of the pair of second side wall portions 322. The inner surface 3q is provided at a position aligned with the rotation axis AX in a direction between the +X direction and the +Y direction across the routing member 4.

[0035] (operation) As shown in FIG. 4, when the sliding door DR is closed, the second protector 3 is rotated to the extended position P1 in accordance with the wiring member 4 in the extended position. As the sliding door DR slides in the opening direction, the wiring member 4 is gradually bent. According to the bending movement of the wiring member 4, the second protector 3 gradually rotates toward the bent position P2. When the sliding door DR is completely opened, as shown in FIG. 6, the second protector 3 rotates to the bent position P2 in accordance with the wiring member 4 in the bent position. After that, when the sliding door DR moves in the closing direction, the second protector 3 gradually rotates toward the extended position P1 in accordance with the extending movement of the wiring member 4. When the sliding door DR is completely closed, as shown in FIG. 4, the second protector 3 rotates again to the extended position P1 in accordance with the wiring member 4 in the extended position.

[0036] (Action and Effects) According to the power supply device 1 of the present embodiment, the outer surface 3s of the second protector 3 is shaped to conform to the routing member 4 passing through the second protector 3 at the extended position P1. With such a shape, the second protector 3 can be shaped to conform to the movement of the routing member 4. Therefore, the power supply device 1 can be made compact.

[0037] As a comparative example, as shown in FIG. 8, when the shape around the rotation axis of the second protector is cylindrical and the outer surface has a shape along a circular arc, an unused portion Sd is created in the circular arc portion. On the other hand, the first protector that houses the second protector needs to house the portion Sd, and therefore the outer diameter of the first protector becomes large. In contrast to this comparative example, according to the power supply device 1 of the present embodiment, the portion Sd can be omitted, and therefore the dimension of the first protector 2 in the Y direction can be reduced. Therefore, as described above, the power supply device 1 can be made smaller.

[0038] According to the power supply device 1 of the present embodiment, since the outer surface 3s of the second protector 3 is flat, the second protector 3 has a shape that is easy to process and also has a shape that fits the wiring member 4 passing through the second protector 3 at the extension position P1. Therefore, the power supply device 1 can be made small and has a shape that is easy to process.

[0039] According to the power supply device 1 of the present embodiment, the inner surface 3q of the second protector 3 has a curved shape that follows the bending posture of the wiring member 4 passing through the second protector 3 at the bending position P2. Due to this curved shape, the power supply device 1 can maintain a smooth bending of the wiring member 4.

[0040] According to the power supply device 1 of this embodiment, the inner surface 3q of the second protector 3 is connected to the base end opening 3a, and is curved toward the +Y direction as it moves toward the -X direction when the second protector 3 is in the bending position P2. Due to this curvature, the power supply device 1 can maintain a smooth bending of the wiring member 4 from the base end opening 3a toward the tip end opening 3b.

[0041] According to the power supply device 1 of this embodiment, since the central axis AC of the tip tube portion 3t of the second protector 3 is located on the -Y side of the rotation axis AX, the rotation axis AX of the second protector 3 can be shifted to the +Y side with respect to the wiring member 4 in the extended position. Therefore, the structure on the -Y side of the power supply device 1 can be reduced in size.

[0042] (Modification) In this embodiment, the outer surface 3s is flat. On the other hand, the outer surface 3s may have any shape as long as it is a shape that conforms to the routing member 4 passing through the second protector 3 at the extension position P1. As a modified example, the outer surface 3s may be a curved surface that conforms to the routing member 4 passing through the second protector 3 at the extension position P1.

[0043] In this embodiment, the rotation range of the second protector 3 is a range slightly larger than 90°. On the other hand, the rotation range of the second protector 3 may be any rotation range as long as it does not exceed the allowable bending range of the routing member 4. As a modified example, when the allowable bending range of the routing member 4 is small, the rotation range of the second protector 3 may be 90°. As another modified example, when the allowable bending range of the routing member 4 is even smaller, the rotation range of the second protector 3 may be a range less than 90°.

[0044] In this embodiment, the first protector 2 and the second protector 3 are provided on the vehicle body BD side. On the other hand, as long as the power supply device 1 is provided between the vehicle body BD and the sliding door DR, the first protector 2 and the second protector 3 may be configured in any manner. As a first modified example, the first protector 2 and the second protector 3 may be provided on the sliding door DR side. As a second modified example, the power supply device 1 may include two pairs of the first protector 2 and the second protector 3. In the second modified example, one pair of the first protector 2 and the second protector 3 may be provided on the vehicle body BD side. Furthermore, in the second modified example, the other pair of the first protector 2 and the second protector 3 may be provided on the sliding door DR side.

[0045] In this embodiment, the power supply device 1 is provided between a vehicle body BD and a sliding door DR of a vehicle. On the other hand, the power supply device 1 may be provided in any structure as long as it is provided between two structures. As a modified example, the power supply device 1 may be provided between a vehicle body and a hinged door of a vehicle. As another modified example, the power supply device 1 may be provided between the body and a door of an aircraft, a ship, or the like.

[0046] In this embodiment, the inner surface 3q of the second protector 3 has a curved shape. However, the inner surface 3q may have any shape as long as the smooth bending of the routing member 4 can be maintained. For example, the radius of curvature of the inner surface 3q of the second protector 3 may be configured to be larger than the radius of curvature allowed for the routing member 4.

[0047] In this embodiment, the first opening 2a opens to the +X direction side on the +X direction side of the first protector 2. On the other hand, the first opening 2a may open to any direction on the +X direction side. As a modified example, the first protector 2 may be configured as a first protector 502 shown in Fig. 9. The first protector 502 is bent and extends in the Z direction on the +X direction side, and a first opening 502a is open on the Z direction side.

[0048] In this embodiment, the wiring member 4 is a harness. On the other hand, the wiring member 4 may be any wiring member as long as it includes an electric wire for supplying power. As a modified example, the wiring member 4 may be an FPC (Flexible Printed Circuit). As another modified example, the wiring member 4 may be an FFC (Flexible Flat Cable).

[0049] Although the embodiment of the present disclosure has been described above, this embodiment is shown as an example and is not intended to limit the scope of the present disclosure. This embodiment can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the present disclosure.
