In this specification, ordinal numbers are used only for distinguishing parts, members, parts, positions, directions, etc., and do not indicate order or priority.

[0010] [Embodiment] FIG. 1 is a perspective view of a power supply device 1 according to an embodiment. The power supply device 1 of the present embodiment shown in FIG. 1 is installed, for example, on the ceiling 101 of a vehicle 100 such as a multi-purpose vehicle, and supplies power to devices used in the vehicle interior. The power supply device 1 of the present embodiment includes, for example, a plurality of conductive wiring materials 10 (see FIG. 2), a power supply case 20 that houses the plurality of wiring materials 10, a slide rail 30 connected to the power supply case 20, and a plurality of slide protectors 40 that slidably support the respective end portions 11a of the plurality of wiring materials 10 drawn out to the outside of the power supply case 20 along the slide rail 30. In addition, the power supply device 1 may further include various components such as fixtures and guide mechanisms. Devices used in the vehicle interior are, for example, electronic devices such as lighting, monitors, smartphones, and notebook computers.

[0011] In the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "extending direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the extending direction X, the width direction Y, and the height direction Z are substantially orthogonal to each other. The extending direction X typically corresponds to the longitudinal direction of the power supply case 20, the longitudinal direction (front-rear direction) of the slide rail 30, etc., and extends along the vehicle front-rear direction. The width direction Y typically corresponds to the lateral direction of the power supply case 20, the width direction (left-right direction) of the slide rail 30, etc., and extends along the vehicle width direction. The height direction Z typically corresponds to the thickness direction (height direction) of the power supply case 20, the height direction (up-down direction) of the slide rail 30, etc., and extends along the vehicle up-down direction. Also, unless otherwise specified, each direction used in the following description will be described as the direction in the state where the power supply device 1 is assembled to the vehicle 100.

[0012] FIG. 2 is a plan view of the state where the slide rail 30 of the power supply device 1 is removed, as viewed from the lower side (inside the vehicle compartment) in the height direction Z, and FIG. 3 is a plan view of the state where the slide rail 30 of the power supply device 1 is removed, as viewed from the upper side in the height direction Z. As shown in FIGS. 2 and 3, the plurality of wiring members 10 are each constituted by a flat wiring member 11 that is thin and flexible. The flat wiring member 11 is, for example, a flat wiring member such as an FFC (Flexible Flat Cable) or an FPC (Flexible Printed Circuits). The flat wiring member 11 is formed in a horizontally long rectangular plate shape as a whole along the extending direction X.

[0013] The flat cable 11 is partially accommodated in the accommodation space 25 provided inside the power supply case 20, and a part of the flat cable 11 is drawn out of the power supply case 20 along with one sliding movement in the sliding direction of the slide protector 40, and is introduced into the power supply case 20 along with the other sliding movement in the sliding direction. One end 11a of each flat cable 11 is electrically connected to the connector 45 provided on the slide protector 40, and the other end 11b of each is electrically connected to a battery or the like mounted on the vehicle 100. The plurality of flat cables 11 constitute individual power systems corresponding to the connectors 45 of the plurality of slide protectors 40 respectively.

[0014] The power supply case 20 includes, for example, a first bottom wall 21, a peripheral wall 22, a cable routing portion 23, a mounting portion 24, and a second bottom wall 28 (see FIG. 1). The first bottom wall 21, the peripheral wall 22, and the second bottom wall 28 are structures for partitioning the above-described accommodation space 25 as the internal space of the power supply case 20. The accommodation space 25 is a space in which a plurality of flat cables 11 are accommodated. The first bottom wall 21 and the second bottom wall 28 are formed, for example, in a flat plate shape and extend horizontally along the extending direction X. The first bottom wall 21 and the second bottom wall 28 are arranged to face each other with a space in the height direction Z. Further, a plurality of beads protruding along the height direction Z are provided on the outer surfaces of the first bottom wall 21 and the second bottom wall 28 respectively. The plurality of beads are for reinforcing the power supply case 20 and are formed, for example, in a lattice shape extending along the extending direction X and the width direction Y.

[0015] The peripheral wall 22 extends, for example, along the height direction Z so as to span between the peripheral edge of the first bottom wall 21 and the peripheral edge of the second bottom wall 28. The peripheral wall 22 includes, for example, a first peripheral wall located on one side in the width direction Y, a second peripheral wall located on the other side in the width direction Y, and a third peripheral wall located on one side in the extending direction X. The first peripheral wall and the second peripheral wall extend linearly along the extending direction X. The third peripheral wall is connected to one end of the first peripheral wall and the second peripheral wall in the extending direction X and is curved in an arc shape (semicircular shape) in a convex state on one side in the extending direction X.

[0016] The cable routing portion 23 is connected to, for example, the other ends of the first peripheral wall and the second peripheral wall in the extending direction X, and is curved in an arc shape (semicircular shape) in a convex state on the other side in the extending direction X. Inside the cable routing portion 23, an insertion space portion 27 (see FIG. 3) through which a plurality of flat cables 11 are inserted in an arc shape is provided. One end portion of the insertion space portion 27 is connected to the accommodation space portion 25 of the power supply case 20, and the other end portion of the insertion space portion 27 is connected to an opening portion 26 that communicates with the outside of the power supply case 20. The opening portion 26 is an opening through which the respective end portions 11a of the plurality of flat cables 11 are drawn out to the outside of the power supply case 20.

[0017] The mounting portion 24 is provided, for example, at one end portion of the power supply case 20 in the extending direction X. The mounting portion 24 protrudes from the above-described third peripheral wall of the peripheral wall 22 to one side in the extending direction X. The mounting portion 24 is provided with a mounting hole 24a penetrating along the height direction Z. In the mounting hole 24a, fastening members such as bolts for fixing the power supply case 20 to the ceiling 101 of the vehicle 100 are fastened.

[0018] The power supply case 20 is constituted by, for example, a combination of a plurality of components including a base, a cover, and the like. The base includes the first bottom wall 21, a part of the peripheral wall 22, the cable routing portion 23, and the mounting portion 24, and the cover includes the second bottom wall 28 (see FIG. 1), a part of the peripheral wall 22, the cable routing portion 23, and the remaining part of the mounting portion 24. Then, the base is assembled in a state of being laminated on the cover in the height direction Z. The base and the cover are formed separately from each other and are integrated with each other by a so-called snap fit such as claw fitting. The power supply case 20 is formed in a substantially rectangular parallelepiped shape as a whole when the base and the cover are assembled to each other. The power supply case 20 is formed of, for example, an insulating synthetic resin or the like.

[0019] The accommodation space portion 25 is an internal space portion formed within the power supply case 20 and communicating with the outside through the above-described opening 26. When the plurality of flat cable materials 11 routed in the accommodation space portion 25 are viewed from the height direction Z (see FIG. 3), linear portions in a linear state are respectively arranged on both sides in the width direction Y, and a folded-back portion 11c that connects the linear portions and is in a folded-back state is arranged on the central side in the width direction Y. The folded-back portion 11c is a portion that is folded back in a U shape from one side to the other side in the extending direction X among the plurality of flat cable materials 11 accommodated in the accommodation space portion 25. One of the linear portions is a portion that is connected to one end portion of the folded-back portion 11c among the plurality of flat cable materials 11 accommodated in the accommodation space portion 25 and extends along the extending direction X so as to face the first peripheral wall of the peripheral wall 22. The other of the linear portions is a portion that is connected to the other end portion of the folded-back portion 11c among the plurality of flat cable materials 11 accommodated in the accommodation space portion 25 and extends along the extending direction X so as to face the second peripheral wall of the peripheral wall 22.

[0020] The folded-back portion 11c moves along the extending direction X, for example, as the slide protector 40 slides. Specifically, the folded-back portion 11c can move along the extending direction X between a first position (see FIG. 3) close to the above-described third peripheral wall (attachment portion 24) of the peripheral wall 22 and a second position close to the cable routing portion 23 when it is taken in and out of the opening 26 as the slide protector 40 slides. The plurality of flat cable materials 11 are taken in and out of the opening 26 as the slide protector 40 slides. For this reason, the power supply case 20 is provided with a slide rail 30 (see FIG. 1) that slidably supports the slide protector 40 adjacent to the opening 26.

[0021] Here, in the present embodiment, the plurality of flat cable members 11 are multi-cabled in a vertical posture in which their respective plate thickness directions intersect the height direction Z of the slide rail 30 along the width direction Y within the slide rail 30 and within the power supply case 20. Specifically, in the present embodiment, two flat cable members 11 are multi-cabled in a vertical posture in one internal space portion 30e (see FIG. 4) of the slide rail 30 to be described later, and one flat cable member 11 is cabled in a vertical posture in the other internal space portion 30e. The three flat cable members 11 are accommodated in the insertion space portion 27 of the cable routing portion 23 and the accommodation space portion 25 of the power supply case 20 while maintaining this vertical posture.

[0022] And in the present embodiment, a total of three slide protectors 40 are provided corresponding to the three flat cable members 11 cabled in the internal space portion 30e of the slide rail 30. The three slide protectors 40 support the respective end portions 11a of the three flat cable members 11, connectors 45 electrically connected to the respective end portions 11a are provided respectively, and they are slidably supported with respect to the slide rail 30. That is, the connectors 45 of the three slide protectors 40 are individually electrically connected to each of the three flat cable members 11.

[0023] FIG. 4 is a cross-sectional view of the other end portion (near the opening 26) in the extending direction X of the slide rail 30 of the power supply device 1, and FIG. 5 is a cross-sectional view of one end portion (near the attachment portion 24) in the extending direction X of the slide rail 30 of the power supply device 1. As shown in FIGS. 4 and 5, the slide rail 30 includes, for example, a bottom wall 30a, a pair of first side walls 30b, a pair of top walls 30c, and a pair of second side walls 30d.

[0024] The bottom wall 30a is a portion that constitutes the lower end portion of the slide rail 30. The bottom wall 30a is configured as a flat plate that extends horizontally along the extending direction X that is the longitudinal direction of the slide rail 30. The bottom wall 30a is located on the upper side (ceiling 101 side) in the height direction Z when the slide rail 30 is attached to the ceiling 101 of the vehicle 100.

[0025] A pair of first side walls 30b constitute the outer end portions (outer rails) of the slide rail 30. The pair of first side walls 30b project along the height direction Z from both end portions in the width direction Y of the bottom wall 30a. The pair of first side walls 30b are configured in a flat plate shape that extends horizontally along the extending direction X which is the longitudinal direction of the slide rail 30.

[0026] A pair of top walls 30c constitute the upper end portions of the slide rail 30. The pair of top walls 30c project toward the center side in the width direction Y from the end portions on the side opposite to the bottom wall 30a of the pair of first side walls 30b. The pair of top walls 30c are configured in a flat plate shape that extends horizontally along the extending direction X which is the longitudinal direction of the slide rail 30. The pair of top walls 30c are positioned on the lower side (inside the vehicle compartment) in the height direction Z in a state where the slide rail 30 is attached to the ceiling 101 of the vehicle 100.

[0027] A pair of second side walls 30d constitute the inner end portions (inner rails) of the slide rail 30. The pair of second side walls 30d project along the height direction Z from the end portions on the side opposite to the pair of first side walls 30b of the pair of top walls 30c. Also, the pair of second side walls 30d are positioned at a distance from the bottom wall 30a in the height direction Z. The pair of second side walls 30d are configured in a flat plate shape that extends horizontally along the extending direction X which is the longitudinal direction of the slide rail 30.

[0028] The slide rail 30 configured as described above is provided with a pair of internal space portions 30e surrounded by the bottom wall 30a, the pair of first side walls 30b, the pair of top walls 30c, and the pair of second side walls 30d. The pair of internal space portions 30e are space portions through which a plurality of flat cable materials 11 are inserted. In the present embodiment, among the pair of internal space portions 30e, two flat cable materials 11 are multi-cabled in a vertical posture on one side on the outer side in the width direction Y, and one flat cable material 11 is cabled in a vertical posture on the other side on the inner side in the width direction Y.

[0029] Further, the slide rail 30 is provided with an external space portion 30f surrounded by a bottom wall 30a and a pair of second side walls 30d. The external space portion 30f is a space portion through which the slide protector 40 is inserted. The external space portion 30f is provided between a pair of internal space portions 30e and communicates with the pair of internal space portions 30e through an opening between the bottom wall 30a and the pair of second side walls 30d. In the present embodiment, the slide protector 40 (see FIG. 5) is accommodated across between the external space portion 30f and one of the pair of internal space portions 30e.

[0030] In the present embodiment, the plurality of flat wire members 11 are configured to have different overall lengths from each other. Specifically, in the present embodiment, among the three flat wire members 11 arranged side by side in the width direction Y, the overall length gradually becomes shorter in the order of the flat wire member 11 arranged on the outer side (outermost periphery) in the width direction Y, the flat wire member 11 arranged in the middle in the width direction Y, and the flat wire member 11 arranged on the inner side (innermost periphery) in the width direction Y.

[0031] FIG. 6 is a perspective view of the slide protector 40 of the power supply device 1. As shown in FIG. 6, the slide protector 40 includes, for example, a base 41, a cover 42, a side cover 43, and a connector 45. The base 41, the cover 42, and the side cover 43 are formed of, for example, an insulating resin material or the like. The base 41, the cover 42, and the side cover 43 are formed separately from each other and are integrated with each other by a so-called snap fit by claw fitting of claw portions 41d and 42d.

[0032] The base 41 is a portion that constitutes a main body portion that is inserted into the external space portion 30f (see FIG. 5) of the slide rail 30 together with the cover 42 among the slide protectors 40. The base 41 includes, for example, a bottom wall 41a, side walls 41b, a pair of end walls 41c, and claw portions 41d. The bottom wall 41a, the side walls 41b, and the pair of end walls 41c are structures for partitioning the internal space portion 44 of the main body portion. The internal space portion 44 is a space portion through which wiring members such as bus bars that electrically connect the end portion 11a of the flat wire member 11 and the connector 45 described above are inserted and routed.

[0033] The bottom wall 41a is formed, for example, in a flat plate shape and is slidably supported on the bottom wall 30a (see FIG. 5) of the slide rail 30 described above. The side wall 41b is formed to project along the height direction Z from one end in the width direction Y of the bottom wall 41a, and the pair of end walls 41c are formed to project along the height direction Z from both ends in the extending direction X of the bottom wall 41a. In the base 41, the space portion surrounded by the bottom wall 41a, the side wall 41b, and the pair of end walls 41c functions as the internal space portion 44 described above. Further, a claw portion 41d for engaging with the cover 42 is provided at the end of the side wall 41b on the side opposite to the bottom wall 41a.

[0034] The cover 42 is assembled to the base 41 and covers (closes) the internal space portion 44 in the base 41. The cover 42 includes, for example, a top wall 42a, a side wall 42b, and a protruding portion 42c. The top wall 42a and the side wall 42b are structures for partitioning the internal space portion 44 of the main body portion described above. The side wall 42b is formed, for example, in a flat plate shape along the side wall 41b of the base 41 and is assembled in a state of covering the internal space portion 44. The top wall 42a is formed to project along the width direction Y from the end of the side wall 42b. A portion to be engaged, which is engaged with the claw portion 41d of the base 41, is provided on the top wall 42a.

[0035] The protruding portion 42c is formed to project from the side wall 42b toward the other side in the width direction Y (the side opposite to the base 41). The protruding portion 42c includes, for example, a bottom wall, a side wall, a pair of end walls, a top wall, etc., and is configured substantially the same as the base 41. The bottom wall, the side wall, the pair of end walls, and the top wall are structures for partitioning the internal space portion 46 of the protruding portion 42c. The internal space portion 46 is, for example, a space portion through which the end portion 11a of the flat cable material 11 described above is inserted and routed. Further, a claw portion 42d for engaging with the side cover 43 is provided on the top wall of the protruding portion 42c.

[0036] The side cover 43 is a part that constitutes a protruding portion inserted into the internal space portion 30e (see FIG. 5) of the slide rail 30 together with the protruding portion 42c of the cover 42 among the slide protectors 40. The side cover 43 includes, for example, a top wall 43a and a side wall 43b. The top wall 43a and the side wall 43b are structures for partitioning the above-described internal space portion 46 of the protruding portion 42c. The side wall 43b is formed, for example, in a flat plate shape along the side wall 42b of the cover 42 and is assembled in a state of covering the internal space portion 46. The top wall 43a is formed to protrude along the width direction Y from the end of the side wall 43b. The top wall 43a is provided with a locked portion that is locked to the claw portion 42d of the protruding portion 42c.

[0037] The connector 45 is a part connected to a device used in the passenger compartment of the vehicle 100. The connector 45 is provided, for example, at an end portion of the base 41 opposite to the bottom wall 41a and is configured as a socket connected to the power plug of the device. The connector 45 may be provided in a state of being exposed with respect to the base 41, or may be provided, for example, in a state of being covered by an openable lid member or the like. The connector 45 is electrically connected to the end portion 11a of the flat cable 11 via a wiring member such as a bus bar routed between the internal space portion 44 of the base 41 and the internal space portion 46 of the protruding portion 42c. Note that the connector 45 is not limited to this example. For example, a connector 45 provided at the end portion 11a of the flat cable 11 may be provided so as to be exposed on the outer surface of the slide protector 40 via the internal space portion 46 of the protruding portion 42c and the internal space portion 44 of the base 41.

[0038] As described above, in the power supply device 1 of the present embodiment, the plurality of flat cable materials 11 are arranged in a vertically stacked posture in which their respective plate thickness directions intersect the height direction Z of the slide rail 30 along the width direction Y within the slide rail 30 and within the power supply case 20, and each connector 45 of the plurality of slide protectors 40 is electrically connected individually to each of the plurality of flat cable materials 11. With this configuration, the power supply device 1 can, for example, arrange (accommodate) more flat cable materials 11 within the slide rail 30 and within the power supply case 20, and thus can provide a plurality of slide protectors 40 corresponding to the flat cable materials 11. As a result, the power supply device 1 can increase the power supply ports (connectors 45) for the devices used in the passenger compartment of the vehicle 100. Further, since the plurality of slide protectors 40 are relatively movable within the slide rail 30, for example, if there are two devices to be powered within the same slide rail 30 and these two devices move relative to each other, power supply can be performed simultaneously.

[0039] Also, in the power supply device 1 of the present embodiment, the plurality of flat cable materials 11 are configured to have different overall lengths from each other. With this configuration, the power supply device 1 can, for example, correspond to a plurality of strokes in the extending direction X of the slide rail 30 for the devices used in the passenger compartment of the vehicle 100.

[0040] Also, in the power supply device 1 of the present embodiment, the number of the plurality of flat cable materials 11 is three or more, and the plurality of slide protectors 40 are provided corresponding to each of the plurality of flat cable materials 11. With this configuration, the power supply device 1 can provide, for example, a power supply device 1 capable of connecting to three or more devices in the passenger compartment of the vehicle 100 by the connectors 45 of the plurality of slide protectors 40.

[0041] In addition, in the power supply device 1 of the present embodiment, the power supply case 20 and the slide rail 30 are installed on the ceiling 101 of the vehicle 100, and the plurality of slide protectors 40 are configured to be manually slidable along the slide rail 30 with respect to the slide rail 30. With this configuration, the power supply device 1 can provide, for example, a power supply device 1 that allows a user to manually move the slide protector 40 along the slide rail 30 to an arbitrary position and connect it to a device in the passenger compartment of the vehicle 100.

[0042] In the present embodiment, the case where three slide protectors 40 and flat cable members 11 are provided on the slide rail 30 has been exemplified, but the present invention is not limited to this example. For example, four or more slide protectors 40 and flat cable members 11 may be provided on the slide rail 30. Further, in the present embodiment, the case where the power supply case 20 and the slide rail 30 are installed on the ceiling 101 of the vehicle 100 has been exemplified, but the present invention is not limited to this example. For example, the power supply case 20 and the slide rail 30 may be installed on the floor panel or the like of the vehicle 100. Further, in the present embodiment, the case where power is supplied to at least devices used in the passenger compartment of the vehicle 100 by the flat cable member 11 and the slide protector 40 has been exemplified, but the present invention is not limited to this example. For example, power may be supplied to devices used outside the passenger compartment of the vehicle 100 (for example, speakers installed on the roof panel).

[0043] Although the embodiments of the present invention have been exemplified above, the above embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Further, the specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) of each configuration, shape, etc. can be appropriately changed and implemented.
