=== Extensible arm ===
Hereinafter, an example of the telescopic arm according to the present embodiment will be described with reference to FIGS. 1 to 4.
FIG. 3 is a diagram illustrating the charging device in which the arm 2 is contracted as viewed in the + Y direction in FIG. 1. FIG. 4 is a view showing the internal structure of the telescopic arm 292.

  Since the structure in which the telescopic arm 291 expands and contracts along the X axis is the same as the structure in which the telescopic arm 292 expands and contracts along the X axis, the structure in which the telescopic arm 292 expands and contracts along the X axis will be described. A description of the structure in which 291 expands and contracts along the X axis is omitted.

  The telescopic arm 292 is an arm that expands and contracts along the X axis in a state where the charging cable 4 is supported, for example, on the lower side (−Z side) of the telescopic arm 292. The telescopic arm 292 is expanded and contracted by adjusting the length of the inner tube member 32 inserted into the outer tube member 31.

  The telescopic arm 292 includes a shaft member 301, a guide member 302, and a stopper member 303 (regulation mechanism) inside the telescopic arm 292. The shaft member 301 and the guide member 302 are members that guide the movement of the inner tube member 32 along the X axis in a state where the inner tube member 32 is inserted into the outer tube member 31. The shaft member 301 has, for example, a substantially cylindrical shape, and is attached to the end member 24 inside the outer tube member 31 in a state along which the central axis of the diameter is substantially parallel to the central axis of the diameter of the outer tube member 31. . The shaft member 301 has a diameter shorter than the inner diameter of the inner tube member 32, and the length in the longitudinal direction is, for example, the same length as the length of the outer tube member 31 in the longitudinal direction. The shaft member 301 is in a state where the central axis of the diameter is substantially parallel to the central axis of the diameter of the outer tube member 31, and the −X side end of the shaft member 301 is the −X side of the outer tube member 31. Is attached to the surface of the end member 24 on the + X side at the approximate center of the opening. The guide member 302 is, for example, a cylindrical member attached to, for example, the inside of the opening on the −X side of the inner tube member 32. The outer diameter of the guide member 302 is shorter than the inner diameter of the opening on the −X side of the inner tube member 32, and the outer peripheral surface of the guide member 302 is the inner tube member 32 in a state where the central axis of the guide member 302 is along the X axis. For example, it is bonded to the inside of the opening on the −X side. The shaft member 301 is inserted through the opening of the guide member 302. The stopper member 303 is a member for preventing the shaft member 301 inserted through the opening of the guide member 302 from coming off the guide member 302. The stopper member 303 is, for example, a cylindrical member attached to the + X side end of the shaft member 301. The outer diameter of the stopper member 303 is longer than the inner diameter of the guide member 302 and shorter than the inner diameter of the inner tube member 32. The inner diameter of the stopper member 303 is longer than the outer diameter of the shaft member 301 and is bonded to, for example, the + X side end of the shaft member 301.

  Therefore, for example, when the inner tube member 32 is moved to the + X side in a state where the inner tube member 32 is inserted into the outer tube member 31, the telescopic arm 292 extends. On the other hand, for example, when the inner tube member 32 is moved to the −X side in a state where the inner tube member 32 is inserted into the outer tube member 31, the telescopic arm 292 contracts.

=== Connected body ===
Hereinafter, with reference to FIG.1 and FIG.7, an example of the coupling body which concerns on this embodiment is demonstrated.
FIG. 7 is a diagram illustrating the charging device in which the arm 2 is rotated in the height direction when FIG. 1 is viewed in the + Y direction.

The connecting body 20 is a member that supports the −X side end of the arm 2 so that the arm 2 expands and contracts along the X axis. The connecting body 20 is a member that rotates the arm 2 in, for example, the height direction (Z-axis direction) and the horizontal direction (XY plane direction).
The connecting body 20 includes an arm support member 21, a connecting member 22 (second rotating mechanism), and a rotating member 23 (first rotating mechanism).

  The rotating member 23 is a member that rotates the arm 2 in the horizontal direction about the shaft 231. The rotating member 23 has, for example, a substantially cylindrical shape, and is attached to the −X side surface of the end member 24 with a shaft 231 provided at the center of the diameter facing the height direction. Here, the surface on the −X side of the end member 24 is assumed to have a shape along the outer peripheral surface of the rotating member 23 so that the rotating member 23 is attached. The arm support member 21 and the connecting member 22 are members that rotate the arm 2 in the height direction about the shaft 219. The arm support member 21 is supported by the elevating member 191 inside the housing 1 with the end on the −X side protruding in the + X direction from the hole 12 of the housing 1. Details of the elevating member 191 will be described later. The arm support member 21 has a shape in which the end on the + X side is fitted with the connecting member 22. The connecting member 22 is a member for connecting the arm support member 21 and the rotating member 23. The connecting member 22 has an end on the + X side attached to the rotating member 23, and an end on the −X side attached to the end on the + X side of the arm support member 21. The + X side end of the connecting member 22 has a shape along the outer peripheral surface of the rotating member 23 so that the rotating member 23 is attached. The end on the −X side of the connecting member 22 is fitted to the end on the + X side of the arm support member 21 so that the end on the + X side of the connecting member 22 is directed upward (+ Z direction). It is assumed that the shape rotates around the shaft 219.

  Here, in order to restrict the rotation of the connecting member 22 so that the + X side end of the connecting member 22 is directed downward (−Z direction), the horizontal stopper 390 is below the arm support member 21. It shall be attached to the side (-Z side). The horizontal stopper 390 includes a horizontal stopper main body 310 and a male screw 311.

  The horizontal stopper main body 310 is, for example, a metal fitting along the lower side of the arm support member 21 and the connecting member 22 when the + X side end of the connecting member 22 is directed in the + X direction, for example. The male screw 311 is a screw for fixing the horizontal stopper main body 310 to the lower side of the arm support member 21. It is assumed that a female screw (not shown) that fits the male screw 311 is provided on the lower surface of the arm support member 21.

  Therefore, for example, when the rotation member 23 is rotated clockwise about the shaft 231 when viewed from above, the arm 2 rotates so that the tip of the arm 2 is directed in the −Y direction. On the other hand, for example, when the rotation member 23 is rotated counterclockwise around the shaft 231 as viewed from above, the arm 2 rotates so that the tip of the arm 2 is directed in the + Y direction.

  Further, for example, when the connecting member 22 is rotated about the shaft 219 so that the + X side end of the connecting member 22 faces upward, the arm 2 is arranged so that the tip of the arm 2 is directed upward. Rotate.

=== Stopper ===
Hereinafter, an example of the stopper according to the present embodiment will be described with reference to FIG.
The stopper 290 is a member for holding a state in which the tip of the arm 2 is directed upward, for example (+ Z direction). The stopper 290 includes a stopper main body 210 and male screws 211 and 212.

  The stopper main body 210 is, for example, an L-shaped metal fitting along the lower side (−Z side) of the arm support member 21 and the + X side of the connecting member 22 when the tip of the arm 2 is directed upward, for example. Each of the male screws 211 and 212 is a stopper main body with the stopper main body 210 being along the lower side of the arm support member 21 and the + X side of the connecting member 22 when the tip of the arm 2 is directed upward, for example. A screw for fixing 210 to the lower side of the arm support member 21 and the connecting member 22 + X side. It is assumed that a female screw (not shown) that fits the male screw 211 is provided on the lower surface of the arm support member 21. Assume that a female screw (not shown) that fits the male screw 212 is provided on the surface of the connecting member 22 on the + X side when the tip of the arm 2 is directed upward.

  Therefore, for example, when the distal end of the arm 2 is directed upward, for example, the stopper body 210 is fixed to the arm support member 21 and the connecting member 22 so that the distal end of the arm 2 is directed upward, for example. State is maintained. When the stopper main body 210 is attached to the arm support member 21 and the connecting member 22, the horizontal stopper main body 310 is assumed to be detached from the arm support member 21. On the other hand, for example, by removing the stopper main body 210 from the arm support member 21 and the connecting member 22, the arm 2 can be rotated in the height direction about the shaft 219.

=== Elevating member ===
Hereinafter, an example of the elevating member according to the present embodiment will be described with reference to FIGS. 1, 5, and 6.

FIG. 6 is a view showing the internal structure of the elevating member 191.
The elevating member 191 is a member that supports the connecting body 20 on the upper side (+ Z side) of the elevating member 191, and moves the connecting body 20 up and down in the height direction (Z-axis direction), for example. The elevating member 191 is disposed inside the housing 1.
The elevating member 191 includes an outer tube member 101, an inner tube member 102, a motor 104, a shaft member 105, stopper members 106 and 108 (regulation mechanism), and a guide member 107.

  The outer tube member 101 has, for example, a substantially cylindrical shape, and the lower (−Z side) end is attached to the lower surface of the housing 1 with the central axis of the diameter along the height direction. The inner tube member 102 has, for example, a substantially cylindrical shape, and the lower end portion is inserted into the upper opening of the outer tube member 101 in a state where the central axis of the diameter is along the height direction. The outer diameter of the inner tube member 102 is shorter than the inner diameter of the outer tube member 101 so that the inner tube member 102 is inserted into the outer tube member 101. An arm support member 21 is attached to the upper end portion of the inner tube member 102.

  The motor 104, the shaft member 105, and the guide member 107 (elevating mechanism) are configured to elevate and lower the inner tube member 102 in the height direction, for example, with the inner tube member 102 inserted into the outer tube member 101. is there.

  The motor 104 is a motor for rotating the shaft member 105 and is attached to the lower surface of the housing 1 inside the outer tube member 101. For example, the rotation of the motor 104 is controlled by a lift button displayed on the control panel 11 of the housing 1. The shaft member 105 has, for example, a substantially cylindrical shape, and is attached to the motor 104 inside the outer tube member 101 in a state where the center axis of the diameter is along the center axis of the outer tube member 101. The shaft member 105 is attached to the motor 104 at the lower end of the shaft member 105. The shaft member 105 has a diameter shorter than the inner diameter of the inner tube member 102, and the length in the longitudinal direction is, for example, the same length as the length of the outer tube member 101 in the longitudinal direction. A thread 105a is provided on the outer peripheral surface of the shaft member 105. It is assumed that the shaft member 105 is rotated by the motor 104, for example, clockwise or counterclockwise as viewed from above. The guide member 107 is, for example, a cylindrical member attached to, for example, the inside of the lower opening of the inner tube member 102. The guide member 107 has an outer diameter shorter than the inner diameter of the lower opening of the inner tube member 102, and the outer peripheral surface of the guide member 107 is in a state where the central axis of the guide member 107 is along the longitudinal direction of the inner tube member 102. For example, it is bonded to the inside of the lower opening of the inner tube member 102. The shaft member 105 is inserted through an opening having a diameter of the guide member 107. It is assumed that a screw groove (not shown) that fits the screw thread 105a of the shaft member 105 is provided in the opening of the guide member 107. When the shaft member 105 rotates clockwise, for example, when viewed from above, the guide member 107 moves upward, and the shaft member 105 rotates, for example, counterclockwise when viewed from above. In this case, the guide member 107 is provided so as to move downward. The stopper members 106 and 108 are members that limit the range in which the guide member 107 moves in the height direction along the shaft member 105. The stopper member 108 limits the range in which the guide member 107 moves upward, and the stopper member 106 limits the range in which the guide member 107 moves downward. The stopper members 106 and 108 are, for example, cylindrical members attached to the shaft member 105. The outer diameters of the stopper members 106 and 108 are longer than the inner diameter of the guide member 107 and shorter than the inner diameter of the inner tube member 102. The inner diameters of the stopper members 106 and 108 are shorter than the outer diameter of the shaft member 105. The stopper member 106 is bonded, for example, between the lower end portion of the shaft member 105 and the guide member 107, for example. For example, the stopper member 108 is bonded to, for example, an upper end portion of the shaft member 105. Here, for example, when the up button of the control panel 11 is pressed, the shaft member 105 is rotated by the motor 104, for example, clockwise as viewed from above. On the other hand, for example, when the down button of the control panel 11 is pressed, the shaft member 105 is rotated by the motor 104 counterclockwise, for example, as viewed from above.

  Therefore, for example, when the up button of the control panel 11 is pressed, the shaft member 105 is rotated, for example, clockwise by the motor 104 as viewed from above. The guide member 107 fixed to the inner tube member 102 moves upward. Therefore, the arm 2 supported by the elevating member 191 via the connecting body 20 is moved upward. On the other hand, for example, when the down button of the control panel 11 is pressed, the shaft member 105 is rotated by the motor 104, for example, counterclockwise as viewed from above. The guide member 107 fixed to the inner tube member 102 moves downward. Therefore, the arm 2 supported by the elevating member 191 via the coupling body 20 is moved downward.

When the arm 2 is extended, the distance between the support members 35 and 36 and the distance between the support members 36 and 37 are extended. Therefore, the charging cable 4 supported by the support members 35, 36, and 37 is It will be in the state along the direction which extends. According to the parking position of the electric vehicle to be charged and the position of the power receiving port on the body of the electric vehicle, for example, the arm 2 is horizontally mounted so that the plug 5 is attached to the power receiving port by rotating the rotating members 23 and 26. It is rotated in the direction (XY plane direction). Further, the arm 2 is moved up and down so that the plug 5 is attached to the power receiving port according to the height of the power receiving port in the body of the electric vehicle. For example, when the height of the power receiving port in the body of the electric vehicle is high, the up button on the control panel 11 of the housing 1 is pressed. In this case, the shaft member 105 of the elevating member 191 disposed in the housing 1 is rotated, for example, clockwise by the motor 104 when viewed from the upper side (+ Z side). Since the guide member 107 moves upward, the inner tube member 102 bonded to the guide member 107 moves upward. Since the arm 2 is supported on the upper side of the inner tube member 102, the arm 2 moves upward. Accordingly, the plug 5 attached to the charging cable 4 supported by the arm 2 moves upward. On the other hand, for example, when the height of the power receiving port in the body of the electric vehicle is low, the down button on the control panel 11 of the housing 1 is pressed. In this case, the shaft member 105 of the elevating member 191 disposed in the housing 1 is rotated, for example, counterclockwise by the motor 104 as viewed from above. Since the guide member 107 moves downward (−Z side), the inner tube member 102 bonded to the guide member 107 moves downward. Since the arm 2 is supported on the upper side of the inner tube member 1, it moves downward. Accordingly, the plug 5 attached to the charging cable 4 supported by the arm 2 moves downward. The plug 5 is attached to the power receiving port of the electric vehicle, and the battery 200 of the electric vehicle is charged by connecting the charger 200 of the housing 1 and the battery of the electric vehicle.

<When charging a battery of an electric vehicle parked near the housing 1>
For example, when the electric vehicle is parked at a position close to the housing 1, the arm 2 is retracted, for example. When the arm 2 is contracted, the distance between the support members 35 and 36 and the distance between the support members 36 and 37 are shortened, so that the charging cable 4 supported by the support members 35, 36 and 37 is bent. Droop. For example, the arm 2 is moved upward so that the charging cable 4 that is bent and drooped is not rubbed and damaged by the ground. Since the operation of moving the arm 2 upward is the same as described above, the description thereof is omitted. The arm 2 is rotated in the horizontal direction so that the plug 5 is attached to the power receiving port of the electric vehicle. Since the operation of rotating the arm 2 in the horizontal direction is the same as described above, the description thereof is omitted. Further, the arm 2 is raised and lowered so that the plug 5 is attached to the power receiving port of the electric vehicle. In addition, since the operation | movement to which the arm 2 is raised / lowered is the same as the above-mentioned, the description is abbreviate | omitted. The plug 5 is attached to the power receiving port of the electric vehicle, and the battery 200 of the electric vehicle is charged by connecting the charger 200 of the housing 1 and the battery of the electric vehicle.

<When storing the arm 2>
For example, in a state where the arm 2 is contracted, the arm 2 is manually rotated, for example, about the shaft 219 so that the tip of the arm 2 faces upward, for example. The stopper main body 210 is fixed to the arm support member 21 and the connecting member 22 by male screws 211 and 212, respectively.

  As described above, the arm 2 expands and contracts along the X-axis direction. The housing 1 accommodates a charger 200 that charges a battery of an electric vehicle. The charging cable 4 connects the charger 200 and the battery. The support members 35, 36, and 37 support the charging cable 4. When the arm 2 is extended, the distance between the support members 35 and 36 and the distance between the support members 36 and 37 are extended, and the charging cable 4 is in a state along the longitudinal direction of the arm 2. When the arm 2 is contracted, the distance between the support members 35 and 36 and the distance between the support members 36 and 37 are contracted, and the charging cable 4 is bent and droops. Therefore, the battery 2 of the electric vehicle parked around the housing 1 for charging the battery and the charger 200 are connected by the charging cable 4 so that the arm 2 is expanded and contracted to connect the plug 5 to the periphery of the electric vehicle. Can be moved to. That is, it is possible to improve the parking position and parking direction for parking the electric vehicle when charging the battery. Further, since the charging cable 4 is supported by the support members 35, 36, and 37, the battery can be charged without the operator supporting the charging cable 4, for example. Further, when the arm 2 is extended, the charging cable 4 is along the longitudinal direction of the arm 2, so that the charging cable 4 is not rubbed on the ground by extending the arm 2 so that the charging cable 4 does not touch the ground. The battery can be charged. Further, when the battery is charged with the charging cable 4 along the arm 2, for example, an operator can be prevented from going to the charging cable 4 during charging, so that a highly safe charging device can be provided.

  The arm 2 is supported by an elevating member 191 disposed inside the housing 1. The arm 2 expands and contracts along the X axis with the tip of the arm 2 protruding in the + X direction from the inside of the housing 1. Therefore, since the arm 2 is integrated with the housing 1, when the charging device 100 is installed in a service station, for example, only the installation space of the housing 1 needs to be secured. Accordingly, a charging device that is compact and easy to install can be provided.

  The support members 35, 36, and 37 are attached to, for example, the lower side (−Z side) of the arm 2. Therefore, since the member etc. for attaching the supporting members 35, 36, and 37 are not required, the number of parts and cost of the charging device can be suppressed.

  Further, the arm 2 and the elevating member 191 are connected by a connecting body 20. The arm 2 is rotated in the horizontal direction (XY plane direction) by the rotating member 23 of the connecting body 20. Therefore, the plug 5 of the charging cable 4 can be accurately moved to the periphery of the electric vehicle. Therefore, the degree of freedom in the parking position and the parking direction for parking the electric vehicle when charging the battery can be improved.

  The arm 2 is rotated by the arm support member 21 and the connecting member 22 so that the tip of the arm 2 faces upward (+ Z side). Therefore, for example, when not charging, the arm 2 is rotated so that the tip of the arm 2 faces upward. Therefore, it is possible to provide a charging device with good storability.

  The elevating member 191 that supports the arm 2 elevates and lowers the arm 2. Therefore, the arm 2 can be moved up and down according to the position of the power receiving port of the electric vehicle, and the plug 5 can be moved to the vicinity of the power receiving port of the electric vehicle. Further, the arm 2 can be moved upward so that the charging cable 4 that is bent and droops does not touch the ground. Therefore, an easy-to-use charging device that can charge the battery without rubbing the charging cable 4 on the ground can be provided.

  A stopper member 303 is attached to the shaft member 301. When the arm 2 is extended in the + X direction, the inner tube members 32 and 34 may fall out of the outer tube members 31 and 33, respectively. Therefore, the inner pipe members 32 and 34 can be prevented from falling off from the outer pipe members 31 and 33, respectively, and a charging device that can be used safely can be provided.

  Further, the stopper members 106 and 108 are attached to the shaft member 105. If the motor 104 of the elevating member 191 continues to rotate, for example, the guide member 107 may fall off the shaft member 105 and the inner tube member 102 may fall off the outer tube member 101. Therefore, the inner pipe member 102 can be prevented from falling off the outer pipe member 101, and a charging device that can be used safely can be provided.

In this embodiment, the arm 2 expands and contracts along the X axis, and the direction in which the arm 2 contracts is defined as the −X direction, and the direction in which the arm 2 extends is defined as the + X direction. The Y axis is an axis orthogonal to both side surfaces of the housing 1, and a direction toward one side surface is defined as a −Y direction, and a direction toward the other side surface is defined as a + Y direction. The Z axis is an axis along the vertical direction with respect to the housing 1, and the downward direction is defined as −Z direction, and the upward direction is defined as + Z direction.

  The arm 2 a is an arm that supports the charging cable 4. The arm 2a is an arm that expands and contracts along the X-axis direction, for example, in a state where the tip is supported from the lower side (−Z side) by the arm auxiliary support portion 6, for example. The arm 2a includes a rotating member 26 and telescopic arms 291a and 292.

  The telescopic arm 291a includes end members 27 and 28a, an outer tube member 33, an inner tube member 34, and a support member 35a. The end member 28a is, for example, a rectangular column-shaped member for attaching the support member 35a and the support leg 61 to the + X side end of the extendable arm 291a. The end member 28 a has a −X side surface attached to the + X side end of the inner tube member 34. Details of the support leg 61 will be described later. The support member 35a is a member that supports the charging cable 4 while being attached to the lower side of the telescopic arm 291a. The support member 35a supports the charging cable 4 while being attached to the lower side of the end member 28a.

  The support member 35a is provided with a hole through which the charging cable 4 is inserted, for example. The charging cable 4 is inserted into the hole of the support member 35 a and fixed by the cable fixing member 49.

The carriage 62 includes a carriage main body 621, for example, four wheels 622. In FIG. 8, only two wheels 622 are shown, but the two wheels on the + Y side overlap the carriage main body 621 and cannot be seen. For example, four wheels 622 for allowing the carriage 62 to travel on the ground, for example, are attached to the lower side of the carriage main body 621.

=== Operation of Charging Device ===
For example, when the arm 2a is extended, the arm auxiliary support portion 6 moves in the + X direction to support the tip of the arm 2a from below. On the other hand, for example, when the arm 2a is contracted, the arm auxiliary support portion 6 moves in the −X direction to support the tip of the arm 2a from below. For example, when the arm 2a is rotated so that the tip of the arm 2a is directed in the + Y direction, the arm auxiliary support portion 6 moves in the + Y direction to support the tip of the arm 2a from below. On the other hand, for example, when the arm 2a is rotated so that the tip of the arm 2a is directed in the −Y direction, the arm auxiliary support portion 6 moves in the −Y direction to support the tip of the arm 2a from below.

  As described above, the tip of the arm 2a is supported by the arm auxiliary support portion 6 so that the arm 2a is along the X direction. Therefore, since the burden of the connection body 20 that connects the arm 2a and the elevating member 191 can be reduced, a charging device having excellent durability can be provided. In addition, for example, an operator can extend and retract the arm 2a by moving the arm auxiliary support portion 6 along, for example, the X-axis direction. Therefore, it is possible to provide a charging device with good operability.

The rail 7 includes, for example, three rail members 711, 712, 713, rail stoppers 714, 715, for example, three support members 75, 76, 77, for example, three attachment members 35b, 37b, 39b.

  The rail members 711, 712, and 713 are members that are connected to each other in a state in which the longitudinal direction is along the X-axis to form, for example, one long connection rail (rail body). The rail members 711, 712, and 713 are long rails whose longitudinal direction is along the X axis. The rail member 711 has a hollow shape so that the end portion on the −X side of the rail member 712 is inserted from the end portion on the + X side. The rail member 712 has a hollow shape so that the end portion on the −X side of the rail member 713 is inserted from the end portion on the + X side. Under the rail members 711, 712, and 713, rail grooves in which the support members 75, 76, and 77 move are provided along the longitudinal direction. Details of the support members 75, 76, and 77 will be described later. The rail grooves of the rail members 711, 712, and 713 are aligned with the X axis when the rail member 713 is inserted into the rail member 712 and the rail member 712 is inserted into the rail member 711 to form one rail. It shall be one rail groove. The rail members 711, 712, and 713 are provided with mounting members 35b, 37b, and 39b below the arm 2b so that the rail groove of the connecting rail to which the rail members 711, 712, and 713 are connected is substantially parallel to the arm 2b. Attached through. The attachment members 35b, 37b, and 39b are, for example, spacers that are attached between the arm 2b and the connection rail so that the rail groove of the connection rail is substantially parallel to the arm 2b. For example, the lower side of the end member 28 and the upper side (+ Z side) of the rail member 713 are bonded via the attachment member 35b. For example, the lower side of the end member 27 and the upper side of the rail member 712 are bonded via an attachment member 37b. For example, the lower side of the end member 24 and the upper side of the rail member 711 are bonded via the attachment member 39b. The support members 75, 76, and 77 are members that move along the rail groove of the connecting rail to which the rail members 711, 712, and 713 are connected in a state where the charging cable 4b is supported. The support member 75 has, for example, a shape in which the upper side is fitted in the rail groove of the connecting rail and moves along the rail groove. The support member 75 supports the charging cable 4b while being fitted in the rail groove of the connecting rail. The support member 75 is provided with a hole through which, for example, the charging cable 4b is inserted. The charging cable 4 b is inserted through the hole of the support member 75 and fixed by the cable fixing member 49. The support member 76 has the same shape as the support member 75, and is fitted, for example, on the −X side from the position where the support member 75 is fitted in the rail groove of the connecting rail. The support member 77 has the same shape as the support member 75, and is fitted, for example, on the −X side from the position where the support member 76 is fitted in the rail groove of the connecting rail. The rail stoppers 714 and 715 are members that block the rail grooves in order to prevent the support members 75, 76, and 77 from falling off the rail grooves of the connecting rail. The rail stopper 714 is attached to the end of the rail member 711 on the −X side, for example. The rail stopper 715 is attached to the end of the rail member 713 on the + X side, for example.

=== Operation of Charging Device ===
For example, when the arm 2b is extended, the rail members 712 and 713 inserted in the rail members 711 and 712 are pulled out, and the connecting rail is extended. On the other hand, for example, when the arm 2b is contracted, the rail members 712 and 713 are inserted into the rail members 711 and 712, respectively, and the connecting rail is contracted. Further, for example, the support members 75, 76, and 77 are connected to the −X side end of the connecting arm along the rail groove, an intermediate position between the −X side end and the + X side end, and the + X side end, respectively. The distance between the support members 75 and 76 and the distance between the support members 76 and 77 are increased. Therefore, the charging cable 4b supported by the support members 75, 76, 77 is in a state along the rail. On the other hand, for example, when the support members 75, 76, 77 are moved along the rail groove to the −X side end of the connecting arm, the distance between the support members 75, 76 and the distance between the support members 76, 77 are Shrink. Therefore, the charging cable 4b supported by the support members 75, 76, 77 is bent and droops.

  As described above, the rail 7 is attached to, for example, the lower side of the arm 2b so that the rail groove of the connecting rail is substantially parallel to the arm 2b. The support members 75, 76, and 77 move along the rail groove of the rail 7 while supporting the charging cable 4b. Therefore, the plug 5b can be quickly moved to the periphery of the electric vehicle by moving the support members 75, 76 and 77 along the rail groove of the rail 7 without expanding and contracting the arm 2b. Further, since the positions of the support members 75, 76, 77 on the rail 7 can be adjusted without extending or retracting the arm 2b, for example, charging is performed near the housing 1 so that workers do not reach the charging cable 4 during charging, for example. The cable 4b can be bent to allow the charging cable 4b to follow the rail 7 near the tip of the arm 2b. Therefore, a user-friendly charging device can be provided.

[Fourth embodiment]
=== Charging device ===
FIG. 10 is a perspective view showing the charging apparatus according to the present embodiment. Note that the same components as those shown in FIG. 1 are only given the same reference numerals, and the description thereof is omitted. FIG. 11 is a diagram illustrating the arm and the charging cable when FIG. 10 is viewed in the −X direction.

  The charging device 100c includes a housing 1, an arm 2c, and a charging cable 4c. In this embodiment, the arm 2 expands and contracts along the X axis, and the direction in which the arm 2 contracts is defined as the −X direction, and the direction in which the arm 2 extends is defined as the + X direction. The Y axis is an axis orthogonal to both side surfaces of the housing 1, and a direction toward one side surface is defined as a −Y direction, and a direction toward the other side surface is defined as a + Y direction. The Z axis is an axis along the vertical direction with respect to the housing 1, and the downward direction is defined as −Z direction, and the upward direction is defined as + Z direction.

The charging cable 4c is a power cable that connects the charger 200 accommodated in the housing 1 and a battery provided in the electric vehicle.
The arm 2c is an arm that supports the charging cable 4c. The arm 2c is an arm that expands and contracts along the X axis in a state where the tip projects from the front of the housing 1 toward the + X direction, for example. The end of the arm 2c on the −X side is attached to the + X side of the connector 20. The arm 2c includes an end member 24c, an outer tube member 31c, an inner tube member 32c, and a support member 35c.

  The end member 24 c is a member for attaching the arm 2 c to the + X side of the coupling body 20. The outer tube member 31c is, for example, C-shaped steel in which the groove is directed downward (−Z side) and the longitudinal direction is along the X axis. The inner tube member 32c is, for example, C-shaped steel in a state where the groove is directed downward and the longitudinal direction is along the X axis, like the outer tube member 31c. In addition, the outer peripheral surface of the inner tube member 32c has a shape along the inner surface of the outer tube member 31c so that the inner tube member 32c is inserted into the outer tube member 31c from the + X side end of the outer tube member. Shall. The inner pipe member 32c is moved along the X-axis while being inserted into the outer pipe member 31c. The end member 24c has a shape along the outer peripheral surface of the rotating member 23 so that the −X side surface is attached to the rotating member 23, and the + X side surface has, for example, a planar shape. The support member 35c is a member that supports the charging cable 4c while being attached to the inside of the inner tube member 35c. The support member 35c is attached to the end portion on the + X side of the inner tube member 35c. The support member 35c is provided with a hole through which the charging cable 4c is inserted, for example. The charging cable 4 c is inserted through the hole of the support member 35 c and fixed by the cable fixing member 49. A support member (not shown) having the same shape as the support member 35c is attached to the lower surface of the end member 24c, inside the outer tube member 31c. The end member 24 c has a −X side surface attached to the rotating member 23. In the outer tube member 31c, the end portion on the −X side of the outer tube member 31c is attached to the surface on the + X side of the end member 24c. The inner tube member 32c is inserted into the outer tube member 31c at the −X side end of the inner tube member 32c from the + X side end of the outer tube member 31c.

=== Operation of Charging Device ===
For example, when the inner tube member 32c is moved to the + X side in a state where the inner tube member 32c is inserted into the outer tube member 31c, the arm 2c extends. Therefore, the distance between the support member 35c and the support member attached to the inside of the outer tube member 31c, the support member attached to the inside of the outer tube member 31c and the support attached to the lower surface of the end member 24c. Since the distance between the members increases, the charging cable 4c is in a state along the arm 2c inside the arm 2c. On the other hand, for example, when the inner tube member 32 moves to the −X side in a state where the inner tube member 32c is inserted into the outer tube member 31c, the arm 2c contracts. Therefore, the distance between the support member 35c and the support member attached to the inside of the outer tube member 31c, the support member attached to the inside of the outer tube member 31c and the support attached to the lower surface of the end member 24c. Since the distance between the members shrinks, the charging cable 4c bends and hangs down from the groove of the arm 2c.

  As described above, as the outer tube member 31c and the inner tube member 32c, for example, C-shaped steel in which the groove is directed downward (−Z side) and the longitudinal direction is along the X axis is used. The support member 35c is attached inside the inner tube member 32c. Therefore, for example, when the arm 2c is extended, the charging cable 4c is in a state along the arm 2c inside the arm 2c, so that the magnetic field due to the energizing current of the charging cable 4c is suppressed from being applied to the periphery of the charging device. it can.

  The first to fourth embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.

For example, the elevating member 191 may be installed outside the casing 1 adjacent to the casing 1 so that the arm 2 supports the charging cable 4 along the longitudinal direction in which the arm 2 expands and contracts. In this case, the charging cable 4 is detachably attached to the lower side of the arm 2 by, for example, the support members 35, 36, and 37. Further, the lower side of the elevating member 191 installed outside the housing 1 may be placed on, for example, a carriage so that the elevating member 191 can travel on the ground. In this case, the arm 2 can be easily accommodated by running the elevating member 191 with the charging cable 4 removed from the arm 2, for example.
