Detailed Description

(1) Examples of the embodiments

(1.1) overview

As shown in fig. 1, the power supply device 1 according to the present embodiment includes a body 2 attachable to a predetermined mounting surface 71, a plug 3, a power cable 4 interconnecting the body 2 and the plug 3, and a holder 54. The body 2 outputs electric power for charging a battery 82 serving as a power source of the movable object 8 (see fig. 2). The plug 3 is configured to be connectable to a charging port of the secondary battery 82. When the plug 3 is connected to the charging port of the storage battery 82, the body outputs electric power for charging so that electric power can be supplied to the storage battery 82 via the plug 3. The holder 54 holds the plug 3 when the plug 3 is not in use.

The movable object 8 includes a storage battery 82, and moves using electric energy charged in the storage battery 82. In the present embodiment, the movable object 8 is an electric vehicle, but in the present disclosure, it may be, for example, a plug-in hybrid vehicle, an electric cart, an electric two-wheeled vehicle, an electric three-wheeled vehicle, a four-wheeled cart (buggy), or the like that operates by combining the output of an engine and the output of an electric motor. The "electric two-wheeled vehicle" herein includes a motorcycle, an electric motorcycle, and an electric motorcycle. The electric tricycle comprises an electric motorcycle and an electric auxiliary tricycle. The movable object 8 also includes flying objects such as drones and airplanes.

As shown in fig. 1, the body 2 is attached to the mounting surface 71. The "mounting surface 71" referred to in the present disclosure means a surface to which the body 2 of the power supply device 1 is attached, and examples thereof may include a wall surface of a building, a surface of a column, and an attachment surface of a dedicated bracket. Examples of buildings with mounting surfaces 71 include residences, parking lots, offices, hospitals, welfare facilities, art museums, factories, warehouses, sports facilities, shops, schools, lobbies, studios, hotels, transportation facilities, and agricultural facilities. The mounting surface 71 may be along a vertical plane or may be inclined from a vertical plane. The mounting surface 71 is not limited to a flat surface, and may be a rough surface.

As shown in fig. 3, the plug 3 includes: a plug body 31 having a handle 32; and a power supply terminal 38 connectable to the charging port. As described above, when the plug 3 is not in use, the plug 3 is held by the holder 54. In a state where the plug 3 is held by the holder 54, a straight line passing through the tip end of the power supply terminal 38 and the end of the handle 32 opposite to the power supply terminal 38 is inclined with respect to the mounting surface 71, as shown in fig. 6. In the present disclosure, "the straight line is inclined with respect to the mounting surface 71" includes not only the intersection of the straight line with the mounting surface 71 but also the intersection of the straight line with an imaginary plane including the mounting surface 71.

Therefore, in a state where the plug 3 is held by the holder 54, the handle 32 and the mounting surface 71 are separated from each other. As a result, according to the present embodiment, when the user grips the handle 32 with his/her hand and causes the holder 54 to hold the plug 3, interference between the hand and the mounting surface 71 can be reduced. Whereby usability can be improved.

(1.2) details

(1.2.1) general Structure

Hereinafter, the power supply device 1 according to the present embodiment will be described in detail. In the following description, unless otherwise specified, the mounting surface 71 is described as a vertical plane, and a direction in which the mounting surface 71 faces (a direction orthogonal to the mounting surface 71 and away from the mounting surface 71) is defined as a forward direction. The opposite of the forward direction is referred to as the backward direction. The forward direction and the backward direction may be collectively referred to as a "front-back direction". Two opposite directions orthogonal to the front-rear direction and extending along the horizontal plane are defined as "left-right directions".

However, the definition of these directions is not intended to limit the use of the power supply apparatus 1. In addition, arrows indicating respective directions in the drawings are shown for explanatory purposes only and are intangible.

The power supply device 1 according to the present embodiment is a device configured to output electric power so as to supply electric power to a storage battery 82 (see fig. 2) of the movable object 8. In the present embodiment, the power supply device 1 is a charger dedicated to an electric vehicle as the movable object 8. The charger is a normal charger in the present embodiment, but may be a quick charger in the present disclosure.

As described above, the "movable object 8" according to the present disclosure includes the storage battery 82 and travels by using the electric power charged in the storage battery 82. As shown in fig. 2, the movable object 8 includes a storage battery 82 and a charging circuit 81. The battery 82 is mounted on the movable object 8 and serves as a driving source of the movable object 8. The charging circuit 81 is a circuit configured to receive electric power from the power supply device 1 and perform charging of the storage battery 82.

As shown in fig. 1, the power supply device 1 is mounted along a mounting surface 71. The power supply device 1 according to the present embodiment is attached to the mounting surface 71 by a plurality of fasteners (here, screws) and the body 2 is fixed to the mounting surface 71.

As shown in fig. 2, the power supply device 1 according to the present embodiment is controlled by a control device 9. The control device 9 is a device different from the power supply device 1, and is a device for controlling various devices (including facilities) to be controlled. The control device 9 is installed inside a house, for example, and the power supply device 1 is installed outside the house, but the control device 9 and the power supply device 1 may be installed at the same location. The control device 9 outputs a "charging command" for instructing the start of charging and a "stop command" for instructing the stop of charging to at least the power supply device 1 according to the present embodiment, thereby controlling the power supply device 1 and controlling the charging of the storage battery 82 by the power supply device 1.

The control device 9 and the power supply device 1 are configured to be communicable with each other. The term "communicable" used herein means that information can be exchanged directly or indirectly via a network, a repeater, or the like through an appropriate communication scheme (e.g., a wired communication scheme and a wireless communication scheme). That is, the control device 9 and the power supply device 1 can exchange information with each other. In the present embodiment, the control device 9 and the power supply device 1 can bidirectionally communicate with each other, and both the transmission of information from the control device 9 to the power supply device 1 and the transmission of information from the power supply device 1 to the control device 9 are possible.

The control device 9 according to the present embodiment is configured to be communicable with, for example, an information terminal 91 (e.g., a tablet computer, a smartphone, or the like) owned by a user, and can control the power supply device 1 based on an electric signal from the information terminal 91.

As shown in fig. 1, the power supply device 1 according to the present embodiment includes a body 2, a plug 3, a power cable 4, a plug holder 5, an extraction portion 61, and a cable support 62.

(1.2.2) bulk

The body 2 is a part of the storage battery 82 for outputting chargeable power to the movable object 8. In the present embodiment, the body 2 is connected to a power supply (e.g., a commercial AC power supply) via a power connector (not shown) and receives power. The body 2 includes a charging unit 21 (see fig. 2) and a case 22 accommodating the charging unit 21.

The charging unit 21 outputs chargeable power to the storage battery 82 of the movable object 8. As shown in fig. 2, the charging unit 21 includes a communication unit 211, a power supply control unit 212, a relay 213, a protection circuit 214, and a vehicle communication unit 215.

The communication unit 211 is configured to communicate with the control device 9 directly or indirectly via a network, a repeater, or the like. As a communication scheme between the communication unit 211 and the control device 9 (more specifically, a communication unit of the control device 9), an appropriate communication scheme such as a wireless communication scheme or a wired communication scheme is employed. In the present embodiment, the communication party between the communication unit 211 and the control device 9 is, for example, a wired communication scheme based on a communication standard such as a wired LAN (local area network). The communication protocol in the communication between the communication unit 211 and the control device 9 is, for example, ethernet (registered trademark), ECHONET Lite (registered trademark), or the like.

The power supply control unit 212 is configured to control the supply of power from the power supply device 1 to the movable object 8. Here, the power supply control unit 212 controls the supply of power to the movable object 8 by driving the relay 213 in accordance with the charging command and the stop command from the control device 9. Basically, when the communication unit 211 receives a charging command from the control device 9, the power supply control unit 212 turns on the relay 213 (on state) and allows power supply from the power supply device 1 to the movable object 8 to charge the storage battery 82. On the other hand, when the communication unit 211 receives a stop command from the control device 9, the power supply control unit 212 turns off the relay 213 (off state) and stops the supply of power from the power supply device 1 to the movable object 8, thereby stopping the charging of the storage battery 82.

However, the control device 9 controls only the charging of the battery 82. For example, in a state where the battery 82 cannot be charged (for example, the battery 82 is in a fully charged state), the battery 82 is not charged of course. Similarly, even in the case where the plug 3 is not connected to the movable object 8 and the power supply device 1 and the movable object 8 are not electrically connected, the storage battery 82 is naturally not charged. Therefore, in the case where the storage battery 82 cannot be charged in this way, even if a charging command is received from the control device 9, the power supply control unit 212 does not turn on the relay 213 and does not allow the power supply from the power supply device 1 to the movable object 8.

In the present embodiment, the power supply control unit 212 mainly includes a computer system including a memory and a processor. That is, the function of the power supply control unit 212 is realized by the processor executing a program recorded in the memory of the computer system. The program may be recorded in advance in the memory, may be provided through a telecommunication line such as the internet, or may be provided by being recorded in a non-transitory recording medium such as a memory card.

The relay 213 is provided in a supply path of electric power to the battery 82. More specifically, the relay 213 is provided between the power input side connection terminal of the power supply device 1 and the connection terminal of the power cable 4. As a result, when the relay 213 is turned on (in its on state), it is possible to supply electric power from a power source (e.g., an electric power system or a photovoltaic power generation facility) to the storage battery 82 of the movable object 8. On the other hand, when the relay 213 is turned off (in its off state), electric power is not supplied from the power source to the storage battery 82 of the movable object 8. The relay 213 may be controllable by the power supply control unit 212 and may be a mechanical relay with mechanical contacts or a semiconductor relay without mechanical contacts. In the present embodiment, the relay 213 is implemented by a mechanical relay as an example.

The protection circuit 214 is, for example, a circuit for protecting the power supply device 1 and the movable object 8 by opening the relay 213 when an abnormality such as a leakage current or an overcurrent is detected. In addition to the relay 213, the protection circuit 214 may include an element for cutting off the supply of electric power to the movable object 8.

The vehicle communication unit 215 is configured to communicate with the movable object 8 directly or indirectly via a network, a repeater, or the like. As the communication scheme between the vehicle communication unit 215 and the movable object 8, an appropriate communication scheme such as a wireless communication scheme or a wired communication scheme is employed. In the present embodiment, the vehicle communication unit 215 can perform communication for checking the connection between the electric power supply device 1 and the movable object 8, the state of the movable object 8, and the like based on at least a CPLT (control pilot) signal.

In the power supply device 1, as described above, the body 2 is electrically connected to the plug 3 via the power cable 4. In the power supply device 1, when the plug 3 is connected to the movable object 8, the body 2 is electrically connected to the movable object 8 via the power cable 4. As a result, the body 2 can supply electric power to the movable object 8 (the storage battery 82) via the power cable 4, and can communicate with the movable object 8.

The case 22 is a box that houses the charging unit 21. As shown in fig. 1, in the present embodiment, the housing 22 includes a housing body 23 having an opening surface in a front surface, and a cover 24 closing the opening surface of the housing body 23. The housing body 23 includes a top plate 231, a bottom plate 232 (see fig. 5A), a pair of side plates 233, and a rear plate 234 (see fig. 5A). The rear plate 234 (see fig. 5A) is disposed along the mounting surface 71, and in the present embodiment, is attached and fixed to the mounting surface 71 with screws. The top plate 231, the pair of side plates 233, and the bottom plate 232 intersect the mounting surface 71 in a state where the rear plate 234 is attached to the mounting surface 71, and in the present embodiment, they are orthogonal to the mounting surface 71. The width dimension of each side plate 233 in the front-rear direction is shorter than the width dimension of the cover 24 in the left-right direction. Similar to the side plates 233, the width dimensions of the top plate 231 and the bottom plate 232 in the front-rear direction are shorter than the width dimensions of the cover 24 in the left-right direction.

Here, the body 2 includes an outer circumferential surface 25. The outer peripheral surface 25 is a surface forming an outer surface of the body 2, and includes a top surface 26, a bottom surface 27 (see fig. 5A), and an outer side surface 28. The top surface 26 is an upward facing surface, and in the present embodiment, is a surface on the upper side of the top plate 231. The bottom surface 27 is a downwardly facing surface and, in this embodiment, is a surface on the underside of the bottom plate 232. Lateral side surface 28 includes a right side surface 281, a left side surface 282 (see fig. 6), a front surface 283, and a rear surface 284. In the present embodiment, the right side surface 281 is the right side surface of the right side plate 233. In the present embodiment, the left side surface 282 is a left side surface of the left side plate 233. In the present embodiment, the front surface 283 is the front surface of the cover 24. In the present embodiment, the rear surface 284 is a rear surface of the rear plate 234.

As shown in fig. 1, the extraction portion 61 is provided in the bottom plate 232 of the housing 22. The extraction portion 61 is a portion for extracting the power cable 4 connected to the charging unit 21 in the housing 22 to the outside of the housing 22. The plug 3 is connected to an end portion of the power cable 4 which is drawn out through the drawing-out portion 61. The extraction portion 61 will be described later in "(1.2.6) extraction portion and cable support".

(1.2.3) plug

The plug 3 is designed to be connectable to a charging port of the accumulator 82 of the movable object 8. When electric power is output from the body 2 in a state where the plug 3 is connected to the charging port, the electric power may be supplied to the storage battery 82. In addition, in a state where the plug 3 is connected to the charging port, the electric signal output from the movable object 8 may be transmitted to the body 2 via the plug 3 and the power cable 4. As shown in fig. 3A, the plug 3 includes a plug body 31 and a terminal portion 37.

The plug body 31 supports the terminal portion 37 and is connected to the power cable 4. The power cable 4 and the terminal portion 37 are connected to each other via the plug body 31. The plug body 31 includes a handle 32 and a distal end portion 33. In the plug body 31 according to the present embodiment, the power cable 4 is connected to one end of the handle 32.

The handle 32 is a portion that is gripped by the user when the user uses the plug 3. The handle 32 constitutes one end portion on the length axis of the plug body 31. In the present embodiment, as shown in fig. 3A, the handle 32 extends along a straight line (which may be referred to as a first straight line S1).

The term "extending along a straight line" as used in this disclosure means a shape that extends along the straight line without deviating too much from the straight line, and may not be parallel to the straight line, and the entire shape may be approximately elongated along the straight line. Examples of the shape extending along a straight line include a straight line shape, an arc shape, a wave shape, and the like. The handle 32 according to the present embodiment is formed in an arc shape and a bar shape.

The distal end portion 33 is provided integrally with the handle 32. The distal end portion 33 protrudes from one end portion of the length axis of the handle 32 in a direction intersecting the first straight line S1. In short, the protruding direction D1 of the distal end portion 33 intersects a direction parallel to the first straight line S1. In the present embodiment, the angle θ 1 between the direction parallel to the first straight line S1 and the projecting direction D1 is, for example, 0 ° or more and 90 ° or less. The terminal portion 37 is provided inside the distal end portion 33.

The plug body 31 further includes a hook portion 34, an operating portion 35, and a guided portion 36. The hook 34 is a portion to be hooked with respect to the plug holder 5. In the present embodiment, the hook 34 is movable between a hooking position (a position indicated by a solid line in fig. 3A) and a releasing position (a position indicated by a broken line in fig. 3A). The hook portion 34 is interlocked with the operating portion 35, and the hook portion 34 can be switched between the hook position and the release position according to the operation of the operating portion 35 by the user. Here, the "operation" includes, for example, a "pushing operation" in which the operation portion 35 is pushed in, or a "sliding operation" in which the operation portion 35 slides along the surface of the plug body 31.

In the present embodiment, since the hook 34 continuously receives the force toward the hooking position, the hook 34 can be hooked in the hook hole 581 (refer to fig. 5B) of the plug holder 5 by inserting the plug 3 into the plug holder 5. Then, by the "pushing operation" of the operating portion 35, the hook 34 can be switched to the release position, and the plug 3 can be removed from the plug holder 5.

The guided portion 36 is a portion that is guided by the guide portion 57 of the plug holder 5 (see fig. 5B), which will be described later. In the present embodiment, the guided portion 36 includes an elongated protrusion 361 provided on the distal end portion 33. The guided portion 36 may have a shape corresponding to the guide portion 57, and may be, for example, a hole, a rail, a wall, or the like. The elongated protrusion 361 protrudes outward from the lower surface of the distal end portion 33 in a direction (radial direction) perpendicular to the protruding direction D1. The length axis of the elongated protrusion 361 extends along the protruding direction D1.

The terminal portion 37 is connected to a terminal of a charging port of the storage battery 82 of the movable object 8. In the present embodiment, as shown in fig. 3B, the terminal portion 37 includes the power supply terminal 38, the ground terminal 370, and the signal transmission terminal 39. The power supply terminal 38 is a terminal for outputting the power transmitted through the power cable 4 to a charging port of the storage battery 82. In the present embodiment, the power supply terminal 38 includes a plurality of (here, two)

terminals

38a and 38 b. Each of the

terminals

38a and 38b of the power supply terminal 38 extends along the projecting direction D1. The plurality of

terminals

38a and 38b of the power supply terminal 38 all have the same length and have distal end surfaces positioned on the same plane. The power supply terminal 38 includes a plurality of

terminals

38a and 38b in the present embodiment, but may be constituted by one terminal in the present disclosure.

The signal transmission terminal 39 is a terminal to which an electric signal output from the movable object 8 through the charging port is input. In the present embodiment, the signal transmission terminal 39 includes a plurality of (here, two) terminals 39a and 39 b. Each of the terminals 39a and 39b of the signal transmission terminal 39 extends along the protruding direction D1. The plurality of terminals 39a and 39b of the signal transmission terminal 39 all have the same length and have distal end surfaces positioned on the same plane. Each of the terminals 39a and 39b of the signal transmission terminal 39 has a smaller cross-sectional area than each of the

terminals

38a and 38b of the power supply terminal 38. In the present embodiment, the signal transmission terminal 39 includes a plurality of terminals 39a and 39b, but may be constituted by one terminal in the present disclosure. Each of the

terminals

38a, 38b, 39a, and 39b of the power supply terminal 38 and the signal transmission terminal 39 is shorter than the ground terminal 370.

The ground terminal 370 is a terminal for grounding. The ground terminal 370 extends along the protruding direction D1. In this embodiment, there is only one ground terminal 370. However, the ground terminal 370 may be constituted by a plurality of terminals.

(1.2.4) Power Cable

The power cable 4 electrically interconnects the body 2 and the plug 3. The power cable 4 transmits at least the electric power output from the body 2 to the plug 3. In the present embodiment, the power cable 4 also has a function of transmitting an electric signal output from the storage battery 82 of the movable object 8 to the body 2. The power cable 4 is flexible and may be changed in shape, e.g. straightened or wound. In the present embodiment, the power cable 4 includes a plurality of (here, two) power supply lines (not shown), a ground line (not shown), a signal line (not shown), and a sheath 41 covering these. The power supply lines are connected to the

terminals

38a and 38b of the power supply terminal 38, respectively. The signal lines are connected to the terminals 39a and 39b of the signal transmission terminal 39, respectively. The ground line is connected to the ground terminal 370.

(1.2.5) plug holder

As shown in fig. 1, the plug holder 5 is a member having a holder 54, the holder 54 being designed to hold the plug 3 when the plug 3 is not in use. The plug holder 5 is attached to a predetermined position. In the present embodiment, the plug holder 5 is attached to the right side plate 233 of the housing 22, that is, to the right side surface 281 of the body 2. In other words, in the present embodiment, the predetermined position is the right side surface 281 of the body 2. However, in the present disclosure, the predetermined position to which the plug holder 5 is attached may be the left side surface 282. In short, the predetermined position may be any one of the surfaces 29 (here, the right side surface 281 and the left side surface 282) included in the outer peripheral surface 25, intersecting the mounting surface 71, and extending along a vertical plane. In addition, the predetermined position may be selected from the top surface 26, the bottom surface 27, and the front surface 283, or may be the rear surface 284 as long as the rear surface 284 includes a region that is not in contact with the mounting surface 71. In short, the predetermined position may be any one of the outer circumferential surfaces 25 of the body 2.

Here, it has been described that the "predetermined position" according to the present embodiment is any one of the outer circumferential surfaces 25 of the body 2, but in the present disclosure, the "predetermined position" may be the inner side of the body 2. Further, the "predetermined position" according to the present disclosure is not required in the body 2, and may be the mounting surface 71, a bracket dedicated to the plug holder 5, a lever, a wall provided together with the mounting surface 71, or the like, and is not particularly limited as long as it can hold the plug 3.

In the present embodiment, the plug holder 5 is attached below the center of the body 2. In the present embodiment, the plug holder 5 is attached to the body 2 such that the holder 54 is located below the center of the body 2 in the vertical direction. More particularly, the plug holder 5 is attached to the lower end of the surface 29 of the body 2.

In the present disclosure, "the retainer 54 is attached below the center of the body 2" means that at least a part of the retainer 54 is located below the center of the body 2 when the plug holder 5 is attached to the predetermined position. Thus, the plug holder 5 may be attached to a substantially central portion of the body 2 in the vertical direction as long as at least part of the holder 54 is positioned below the center of the body 2 in the vertical direction. As a result, the user can easily cause the holder 54 to hold the plug 3.

As shown in fig. 4, the plug holder 5 includes an attaching portion 51 and a holder 54.

The attachment portion 51 is a portion that is attachable to the attachment surface 72. In the present embodiment, the attaching portion 51 is provided between the holder 54 and the attaching surface 72, and the holder 54 is attached to the attaching portion 51. In the present embodiment, the holder 54 is fixed to the attachment portion 51.

Here, the "attachment surface 72" in the present disclosure means a surface to which the plug holder 5 is attached and a surface at a predetermined position. In the present embodiment, the attachment surface 72 is the surface 29 of the body 2, and is a vertical plane, but may be an inclined surface inclined with respect to the vertical plane, or may be a horizontal plane. The attachment surface 72 is not limited to a flat surface, and may be, for example, an uneven surface, a stepped surface, a wavy surface, or the like. In the present embodiment, the attachment surface 72 is perpendicular to the mounting surface 71 and extends along a vertical plane.

As shown in fig. 4, the attachment portion 51 includes a frame 52 and a housing 53. The frame 52 is a member forming a skeleton of the attaching portion 51. The frame 52 includes a facing surface 521 that faces the attachment surface 72, and a holder fixing surface 522 that is inclined with respect to the facing surface 521. The facing surface 521 and the holder fixing surface 522 are both flat surfaces. With the facing surface 521 facing the attachment surface 72 and in contact with the attachment surface 72, the frame 52 is attached to the attachment surface 72. In this embodiment, the frame 52 is screwed to the attachment surface 72.

In the present embodiment, the holder fixing surface 522 is inclined with respect to the facing surface 521 as viewed in the vertical direction. In particular, the holder fixing surfaces 522 are inclined such that the distance between the holder fixing surfaces 522 and the facing surface 521 becomes larger toward their rear ends. Further, the holder fixing surface 522 is inclined with respect to the facing surface 521 when viewed in the front-rear direction. In particular, the holder fixing surfaces 522 are inclined such that the distance between the holder fixing surfaces 522 and the facing surface 521 becomes smaller toward their lower ends.

The housing 53 covers the frame 52. In the present embodiment, the housing 53 is attached to the frame 52, but may be directly attached to the attachment surface 72. The housing 53 is formed in a hollow prism shape.

The holder 54 is a portion for holding the plug 3 when the plug 3 is not in use. In the present embodiment, the holder 54 is attached to the holder fixing surface 522 of the frame 52 and fixed to the holder fixing surface 522. The holder 54 includes a fixing plate 55, a holding cylinder 56 integrally provided to the fixing plate 55, a guide portion 57, and an engaging member 58 including a hook hole 581.

The fixture plate 55 is fixed to the holder fixing surface 522. In the present embodiment, the fixing plate 55 is formed in a rectangular plate shape. A plurality of through holes 551 are formed in four corners of the fixing plate 55, and the fixing plate 55 is fixed to the frame 52 by screwing screws into the holder fixing surfaces 522 through the through holes 551.

The holding cylinder 56 is a portion into which the plug 3 is inserted. A central axis 561 (see fig. 5B) of the holding cylinder 56 is orthogonal to the fixture plate 55. One end of the holding cylinder 56 near the fixing plate 55 is closed by the fixing plate 55, and thus is formed in a bottomed hollow cylindrical shape. In the present embodiment, the holding cylinder 56 is a circular hollow cylinder. A central axis 561 (see fig. 5B) of the holder cylinder 56 is orthogonal to the holder fixing surface 522.

The guide portion 57 is a portion for guiding the insertion of the plug 3 into the holder 54 in one direction. The guide portion 57 contacts a portion of the plug 3 to restrict movement of the plug 3 in a direction other than one direction (a direction intersecting the one direction). In the present embodiment, the guide direction of the guide portion 57 is inclined with respect to the attachment surface 72. Therefore, in the present embodiment, the guiding direction of the guide portion 57 is also inclined with respect to the mounting surface 71.

In the present embodiment, the guide portion 57 is a groove formed in a portion of the holding cylinder 56, and the groove is parallel to the center axis 561 of the holding cylinder 56. Therefore, in the present embodiment, the "one direction" is parallel to the center axis 561 of the holding cylinder 56, and is inclined with respect to the mounting surface 71 so as to extend downward and forward as extending outward in the left-right direction with respect to the body 2. However, the "one direction" referred to in the present disclosure need not be in a direction extending downward and forward as it extends outward in the left-right direction with respect to the body 2, and may extend in a predetermined direction. Here, the "predetermined direction" means a direction from an arbitrary position toward a position where the plug 3 is appropriately held with respect to the holder 54. In the present embodiment, "one direction" is along a straight line, but in the present disclosure, "one direction" may be along a portion such as a spiral, an arc, or the like.

Here, although the guide portion 57 is formed in a portion of the holding cylinder 56 in the present embodiment, for example, a guide rail parallel to the central axis 561 of the holding cylinder 56 may be provided at a position different from that of the holding cylinder 56, or a guide pin may be provided. Further, the inner peripheral surface of the holding cylinder 56 may serve as the guide portion 57, and the holding cylinder 56 may also serve as the guide portion 57.

The engagement member 58 is a member having a hook hole 581, and the hook portion 34 of the header 3 is hooked in the hook hole 581. In the present embodiment, the engagement member 58 is provided on the holding cylinder 56 and screwed to the fixing plate 55. As a result, the engaging member 58 is fixed to the holding cylinder 56.

In the present disclosure, the position at which the engagement member 58 is provided may be any position corresponding to the hook 34 when the plug 3 is inserted into the holding cylinder 56, and the engagement member 58 may be provided in front of, behind, or below the holding cylinder 56. Further, in the present embodiment, the hook hole 581 is a concave portion having the bottom surface 27, but may be a through hole.

As shown in fig. 5A, the plug 3 is held by the plug holder 5. The user extends the guided portion 36 (elongated projection 361) of the plug 3 along the guide portion 57 and moves the plug 3 toward the plug holder 54. Then, the plug 3 is guided by the guide portion 57 to move in one direction, and the hook 34 is hooked in the hook hole 581. As a result, the plug 3 is held by the holder 54.

In the present embodiment, the guide portion 57 guides the one direction of the plug 3 to be inclined with respect to the mounting surface 71. Therefore, as shown in fig. 6, a straight line S2 (sometimes referred to as a second straight line S2) passing through the center 38c (see fig. 3B) of the distal end of the power supply terminal 38 and the center 321 of the handle 32 on the length axis, which is opposite to the end (hereinafter referred to as the rear end) of the terminal 38, is inclined with respect to the mounting surface 71. Therefore, even if the user grips the handle 32 and puts the plug 3 into the holder 54, it is possible to reduce interference between the hand gripping the handle 32 and the mounting surface 71. In fig. 6, θ 2 represents the angle of the straight line S2 with respect to the mounting surface 71. θ 2 is, for example, greater than 0 ° and less than 90 °. Specifically, θ 2 may be greater than or equal to 5 ° and less than or equal to 45 °. Further, θ 2 may be greater than or equal to 10 ° and less than or equal to 20 °.

In the present disclosure, "the center 38c of the distal end of the power supply terminal 38" means the centroid of the distal end surface of the power supply terminal 38. Therefore, in the present embodiment, as shown in fig. 3B, the center of the distal end of the power supply terminal 38 is the center between the distal end surfaces of the two terminals 38a and 38B of the power supply terminal 38. If the power supply terminal 38 has three terminals, the center of the distal end of the power supply terminal 38 is the centroid of the figure (triangle) formed by connecting the centers of the distal end surfaces of the respective terminals. When the plurality of terminals are arranged in a straight line, the center of the distal end of the power supply terminal 38 is the center of a line segment formed by connecting the centers of the distal end surfaces of the respective terminals. In the present disclosure, "the center 321 of the rear end of the handle 32" means the centroid of the outer shape of the rear end surface of the handle 32.

When the header 3 is held by the holder 54, as shown in fig. 6, the header 3 is located between the first imaginary plane H1 and the second imaginary plane H2. The first imaginary plane H1 is an imaginary plane including an opposite surface (i.e., the front surface 283) of the body 2 from the mounting surface 71. The second imaginary plane H2 is an imaginary plane including the mounting surface 71. In the present embodiment, the second imaginary plane H2 is the mounting surface 71 and is tangible. In the present embodiment, the first imaginary plane H1 and the second imaginary plane H2 are parallel, but may not be parallel. When the header 3 is located between the first imaginary plane H1 and the second imaginary plane H2, storability when the header 3 is held by the holder 54 can be improved.

Here, the term "located between" in the present disclosure includes a case where the first imaginary plane H1 (or the second imaginary plane H2) is located in the same plane as the surface of the header 3. However, in the present embodiment, the header 3 is close to the first imaginary plane H1 and is distant from the second imaginary plane H2.

Further, in the present embodiment, as shown in fig. 7, the guide portion 57 guides the one direction of the plug 3 to be inclined so as to extend upward as it extends in the left-right direction from the plug holder 5 toward the body 2. Therefore, when the user grips the handle 32 and moves the plug 3 toward the plug holder 54, the distal end portion 33 of the plug 3 can be moved while it is located above the handle 32. As a result, the plug 3 can be moved without lifting up the power cable 4 as much as necessary, and thus usability can be improved.

At this time, in a state where the plug 3 is held by the holder 54, the second straight line S2 is inclined to extend upward as it extends from the plug holder 5 toward the body 2. Therefore, the power cable 4 can be hung down along the handle 32 of the plug 3, and storability of the power cable 4 can be improved. The power cable 4 is supported by a cable support 62 provided on the bottom plate 232 of the body 2.

(1.2.6) drawer and Cable support

As shown in fig. 1, the extraction portion 61 is a portion for extracting the power cable 4 connected to the charging unit 21 in the housing 22 to the outside of the housing 22. As shown in fig. 5B, the extraction portion 61 is provided on the bottom plate 232 of the housing 22. As shown in fig. 5B, the withdrawing part 61 is formed in a cylindrical shape protruding downward from the bottom plate 232. However, the withdrawing part 61 may be a through hole formed in the bottom plate 232. The power cable 4 is made to pass through the withdrawing part 61, and the power cable 4 is withdrawn from the bottom surface 27 of the body 2.

The center of the extraction portion 61 is located behind the center of the main body 2 in the front-rear direction. However, the extraction portion 61 may be provided at any position with respect to the bottom surface 27 of the body 2 in the front-rear direction.

The cable support 62 supports a portion of the power cable 4. In the present embodiment, the cable support 62 is positioned on the opposite side of the center of the withdrawing portion 61 from the mounting surface 71 in the direction orthogonal to the mounting surface 71. That is, the cable support 62 is disposed forward of the center of the withdrawing portion 61. In the present disclosure, "the cable support 62 is positioned on the opposite side of the center of the withdrawing portion 61 from the mounting surface 71 in the direction orthogonal to the mounting surface 71" means that the boundary between the connecting portion 621 of the cable support 62 and the bottom plate 232 is located on the opposite side of the center of the withdrawing portion 61 from the mounting surface 71. In the present embodiment, the connection part 621 is linear along the vertical direction, but in the present disclosure, it may be inclined with respect to the vertical plane or formed in a stepped shape. Even in this case, it is sufficient that the upper end of the connecting portion 621 is positioned forward of the center of the extracting portion 61.

The cable support 62 includes a connection portion 621, a support portion 622, and a restriction portion 623. The connection portion 621 is a portion interconnecting the support portion 622 and the bottom plate 232. In the present embodiment, the connecting portion 621 is constituted by a pair of rods extending downward from the bottom plate 232, but may be inclined with respect to the vertical plane as described above. The support 622 is a portion that supports a portion of the power cable 4. In the present embodiment, the support portion 622 extends forward from the lower end of the connection portion 621. The restricting portion 623 restricts movement of the power cable 4 supported by the support portion 622. The restriction portion 623 protrudes upward from the front end of the support portion 622. As shown in fig. 5B, the front ends of the restricting portions 623 are positioned on the same plane as the front surface 283 of the body 2. In short, the front ends of the restricting portions 623 are positioned on the same plane as the first imaginary plane H1.

Here, it is preferable that the front end of the regulating portion 623 is positioned at the same position as the first imaginary plane H1 or behind the first imaginary plane H1 in the front-rear direction. As a result, it is possible to reduce interference of the cable support 62. Further, the cable support 62 is placed in front of the withdrawing part 61, and thus putting the electric power cable 4 on the support 622 (for example, winding the electric power cable 4 around the support 622) may become easier and usability may be improved.

(2) Variants

The above embodiments are only one of various embodiments of the present disclosure. The embodiments may be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Hereinafter, modifications will be described. The following modifications may be applied in combination in an appropriate manner.

(2.1) variation 1

In the power supply device 1 according to the above embodiment, the direction in which the guide portion 57 guides the plug 3 is inclined with respect to the mounting surface 71, but in modification 1, as shown in fig. 8, the direction D2 is along the mounting surface 71. However, in the present modification 1, in a state where the header 3 is rotated about the axis S3 in the projecting direction D1 of the above embodiment, the header 3 is held by the holder 54. The first line S1 (which is the direction in which the handle extends) is inclined with respect to the mounting surface 71. Assuming that the first straight line S1 passes through the first position P1 and the second position P2, the distance a2 between the mounting surface 71 and the second position P2 is longer than the distance a1 between the mounting surface 71 and the first position P1. In the present embodiment, the first position P1 is located at the center of the end of the handle 32 on the length axis near the distal end portion 33. In the present embodiment, the second position is located at the center 321 of the rear end of the handle 32 in the length axis.

According to the present modification, the first straight line S1 is inclined with respect to the mounting surface 71. Therefore, when the plug 3 is held by the holder 54, a straight line S2 passing through the center 38c of the distal end of the power supply terminal 38 and the center 321 of the rear end of the handle 32 is inclined with respect to the mounting surface 71. Therefore, according to the present modification, when the user places the plug 3 on the holder 54, even when the guide portion 57 has a structure that guides the plug 3 to the holder 54 along the mounting surface 71, it is possible to reduce interference between the hand holding the handle 32 and the mounting surface 71.

In the present disclosure, "guide along the mounting surface 71" may not mean guide parallel to the mounting surface 71, but may mean guide along a direction slightly inclined with respect to the mounting surface 71.

(2.2) variation 2

Fig. 9 to 11 show a power supply device 1A of modification 2. The power supply device 1A differs from the power supply device 1 according to the above embodiment in that the plug holder 5A is provided on the left side surface 282 of the housing 22, the left side surface 282 being the left side surface of the body 2. The plug holder 5A includes an attaching portion 51 and a holder 54 having the same structure as the attaching portion 51 and the holder 54 of the plug holder 5. That is, in the power supply device 1 according to the above embodiment, the plug holder 5 is attached to the right side surface 281 of the housing 22, which right side surface 281 is the right side surface of the body 2, but in the power supply device 1A according to the present modification, the plug holder 5A is attached to the left side surface 282 through the use of the attaching portion 51 and the holder 54 having the same structure as the attaching portion 51 and the holder 54 of the plug holder 5. In short, the

plug holder

5, 5A may be attached to a selected one of one surface and the other surface which are opposite surfaces in the direction of the body 2. Thus, for example, the same attachment portion 51 and the same holder 54 can be used to attach the plug holder 5 to the right side surface 281 and the plug holder 5A to the left side surface 282 and thus inventory control and manufacturing expenses can be saved.

As shown in fig. 10 to 12, the plug holder 5A includes an attaching portion 51, a holder 54, and an adjusting member 59. The attaching portion 51 and the holder 54 have the same structure as the above embodiment.

As shown in fig. 11, the adjusting member 59 is a member for adjusting the second straight line S2 so as to be inclined with respect to the mounting surface 71 when the holder 54 holds the plug 3. Similar to the power supply device 1, the regulating member 59 inclines the second straight line S2 at an angle θ 2 with respect to the mounting surface 71. The adjustment member 59 is provided between the attachment portion 51 and the holder 54. More specifically, the adjustment member 59 is provided between the housing 53 and the holder 54.

As shown in fig. 12 and 13, the adjusting member 59 includes a first member 591 and a second member 593.

First member 591 includes a first surface 592. The first surface 592 is a surface facing at least part of a surface of the attachment portion 51. The first surface 592 is a surface (outer surface) on the thickness axis of the first member 591. The first face 592 is flat and faces the space inside the housing 53. The first member 591 is secured to the frame 52 through the use of fasteners F2. More specifically, the first member 591 includes a first flat plate portion 5911 and a pair of first side plate portions 5912. The first flat plate portion 5911 has a rectangular shape. A surface of the first flat plate portion 5911 facing the attachment portion 51 serves as a first surface 592. The pair of first side plate portions 5912 protrude from both end portions in a first direction orthogonal to the thickness axis of the first flat plate portion 5911 toward the second member 593 (the opposite side of the first flat plate portion 5911 from the attachment portion 51). Each first side plate portion 5912 has a triangular shape. Each first side plate portion 5912 protrudes from the first flat plate portion 5911 more and more as it extends from the first end to the second end in the second direction orthogonal to the thickness axis and the first direction of the first flat plate portion 5911. Each of the pair of first side plate portions 5912 includes a pair of through holes 5913, and the fasteners 595 each pass through the pair of through holes 5913. The first flat plate portion 5911 includes a pair of through

holes

5914 and 5914 through which the fasteners F2 pass at both ends in the second direction through the pair of through

holes

5914 and 5914, respectively. The first member 591 is attached to the attachment portion 51 by using the fastener F2 and the through hole 5914.

The second member 593 has a second surface 594. The second surface 594 is a surface facing at least part of the surface of the holder 54. The second surface 594 is a surface (outer surface) on the thickness axis of the second member 593. The second surface 594 is flat and faces the fixing plate 55 of the holder 54. The second member 593 is secured to the retainer 54 using fastener F1. More specifically, the second member 593 includes a second flat plate portion 5931 and a pair of second side plate portions 5932. The second flat plate portion 5931 has a rectangular shape. A surface of the second flat plate portion 5931 facing the holder 54 serves as a second surface 594. The pair of second side plate portions 5932 protrude from both end portions in a first direction orthogonal to the thickness axis of the second flat plate portion 5931 toward the first member 591 (the opposite side of the second flat plate portion 5931 from the holder 54). Here, the first flat plate portion 5911 and the second flat plate portion 5931 are sized such that the pair of second side plate portions 5932 can be disposed between the pair of first side plate portions 5912. Each of the second side plate portions 5932 has a triangular shape. Each second side plate portion 5932 protrudes more and more from the second flat plate portion 5931 as it extends from the first end portion to the second end portion in a second direction orthogonal to the thickness axis of the second flat plate portion 5931 and the first direction. Each of the pair of second side plate portions 5932 includes a pair of threaded holes 5933 corresponding to the fasteners 595. The second flat plate portion 5931 includes a pair of threaded

holes

5934 and 5934 corresponding to the fasteners F1 at both ends in the second direction, respectively. The retainer 54 is attached to the second member 593 using the fastener F1 and the threaded hole 5934.

In this variation, fasteners 595, F1 and F2 are screws. The fasteners F1 and F2 may not be limited to screws, but may be, for example, pins, rivets or the like. However, the attachment of the adjustment member 59 to the attachment portion 51 and the attachment of the holder 54 to the adjustment member 59 may be achieved not only by such fasteners, but also, for example, by bonding, welding, fitting, hook structure, snap-fit structure, or the like.

First and

second members

591, 593 are coupled to each other such that second surface 594 is inclined with respect to first surface 592. More specifically, the first member 591 and the second member 593 are arranged such that the first end and the second end of the first member 591 in the second direction face the first end and the second end of the second member 593 in the second direction, respectively, and such that the pair of second

side plate portions

5932 and 5932 are located between the pair of first

side plate portions

5912 and 5912. The first and

second members

591, 593 are coupled to each other by coupling fasteners 595 through the through holes 5913 to the threaded holes 5933. Thereby obtaining the adjustment member 59 shown in fig. 13.

In the adjusting member 59, the second face 594 is inclined with respect to the first face 592. The angle θ 3 between the second face 594 and the first face 592 satisfies, for example, the relationship 0 ° < θ 3 < 90 °. In particular, in this variant, θ 3 is equal to 2 × θ 2.

The adjusting member 59 (the first member 591 and the second member 593) is made of the same material as the frame 52. Therefore, the rigidity of the regulation member 59 (the first member 591 and the second member 593) is higher than that of the housing 22. The strength of the regulation member 59 (the first member 591 and the second member 593) is higher than that of the housing 22. The first member 591 and the second member 593 of the adjusting member 59 are each formed by bending a metal plate. Examples of the metal plate referred to herein may include a steel plate, a stainless steel plate, and an aluminum plate. However, the regulation member 59 may be made of synthetic resin. The regulation member 59 may not be formed of a plate-like material, and may be formed of, for example, a wedge-like rubber material, a synthetic resin, or the like. The adjusting member 59 may be formed by joining the first flat plate portion 5911 with the second flat plate portion 5931 by welding.

(2.3) other modifications

Other variations of the embodiments are listed below.

In the above embodiment, the mounting surface 71 is larger than the body 2 in the front-rear direction. However, in the present disclosure, the mounting surface 71 may have the same size as the body 2 in the front-rear direction, like a dedicated bracket or the like. Even in this case, when the mounting surface 71 is set adjacent to the surface (vertical surface) along a vertical plane (e.g., a wall surface, a fence surface, a surface or fence spaced by a fence, and a surface spaced by a net or mesh), the interference between the hand and the vertical surface can be reduced similarly to the above embodiment. As a result, usability can be improved even in this modification.

The above embodiment includes the plug holder 5 including the holder 54. However, the holder 54 may be realized by forming a recess having a shape corresponding to the outer shape of the plug 3 in the top plate 231. In this case, the plug 3 is mounted on the holder 54. However, in the present disclosure, "mounting" is also included in the meaning of "holding".

In the above embodiment, the plug 3 is held by being inserted into the holder 54 in one direction, but in the present disclosure, the structure in which the holder 54 holds the plug 3 is not limited to the structure in which insertion is achieved. For example, a hook structure or the like may be used in addition to the above-described mounting structure.

In the above embodiment, the guide portion 57 is included in the holder 54, but in the present disclosure, the holder 54 and the guide portion 57 may be separate members.

The

plug holders

5 and 5A according to the present disclosure may be directly attached to the side plate 233 of the housing 22, or may be attached to the side plate 233 of the housing 22 through another member therebetween. For example, the power supply device 1 or 1A may include an attachment member having a substantially L-shaped cross section. The attachment member includes, for example, a plate portion attached to the mounting surface and a plate portion to which the

plug holder

5 or 5A is attached, and is formed to have a substantially L-shaped horizontal cross section.

Also, in the present disclosure, the expression ". multidot.end" and the expression ". multidot.end" (such as "lower end" and "lower end") have different meanings. For example, "lower end" means a portion having a specific region including the "lower end". The same applies to other expressions of ". multidot.end".

(3) Aspect(s)

As described above, the power supply device 1, 1A according to the first aspect includes the body 2, the plug 3, the power cable 4, and the holder 54. The body 2 is configured to output electric power for charging a storage battery 82 serving as a drive source of the movable object 8, and is attachable to a predetermined mounting surface 71. The plug 3 is connectable to a charging port of the movable object 8. The power cable 4 interconnects the body 2 and the plug 3 and transmits power output from the body 2 to the plug 3. The retainer 54 serves to retain the plug 3 when the plug 3 is not in use. The plug 3 includes a plug body 31 including a handle 32, and a power supply terminal 38 provided to the plug body 31 and connectable to the charging port. A straight line S2 passing through the distal end of the power supply terminal 38 and the opposite end of the handle 32 from the power supply terminal 38 is inclined with respect to the mounting surface 71 while the plug 3 is held by the holder 54.

According to this aspect, when the plug 3 is held by the holder 54, the handle 32 and the mounting surface 71 are separated from each other. Therefore, when the user grips the handle 32 with his/her hand and causes the holder 54 to hold the plug 3, interference between the hand and the mounting surface 71 can be reduced. Whereby usability can be improved.

According to the power supply device 1, 1A of the second aspect to be realized in combination with the first aspect, the connector 3 further includes a guide portion 57 for guiding insertion of the connector 3 into the holder 54 in a predetermined direction.
