Description

  According to the present invention, when a battery that needs to be charged is placed on a charging stand at a predetermined position, such as when the battery is used or the amount of stored power is insufficient, the charging stand is displaced and stored in the casing. The present invention also relates to a magazine-type charging device capable of taking out a newly exposed charged battery from a casing.

  The battery is a clean drive source that does not discharge exhaust gas, etc., and has the advantages that it can be reused if it is charged after the end of discharge, and that it can be easily charged from a commercial power supply. Has been widely used. For example, Patent Literature 1 proposes a battery that can be used as a drive source of an electric scooter (in Patent Literature 1, it is represented as a “portable electric energy storage device”).

  This battery has a cylindrical outer shell having a substantially square cross section and open upper and lower ends, and a cover (top case) and a base (bottom case) located at the upper and lower ends of the outer shell, respectively. Having a housing including: Then, a plurality of individual battery core packs are built in the housing. Further, the cover is provided with a handle. It is said that the user can grip the handle and put the battery in and out of the compartment arranged below the seat of the electric scooter.

  It is preferable that a plurality of charging devices for charging the battery can be charged simultaneously. This is because a large number of charged batteries that can be used when needed can be stored. As this type of charging device, one disclosed in Patent Document 2 is known. This charging device has a plurality of containers that individually store batteries (portable electric energy storage devices), and thus can collect, charge, and distribute batteries.

  A battery or the like used as a drive source of an electric motorcycle or the like is large in size to secure a large capacity, and often has a substantially rectangular parallelepiped shape. When a large battery having such a shape is accommodated in the charging device, it is preferable that the battery be in a vertically long standing posture. This is because setting the battery in the upright position makes it easier to accommodate the battery in the charging device by gravity.

  In this case, the battery-side charging connector is provided on the bottom surface of the battery. Therefore, when the battery is accommodated in the charging device, the user cannot visually recognize the battery-side charging connector. Therefore, if the user accommodates the battery in the charging device in the wrong direction (posture), charging is not performed because the positions of the battery-side charging connector and the device-side charging connector do not correspond to each other. Moreover, in this case, there is a concern that the male device-side charging connector may be damaged.

  The present invention has been made to solve the above-described problem, and is a magazine type capable of preventing a device-side charging connector from being damaged even when a user inserts a battery requiring charging in an incorrect posture. It is an object to provide a charging device.

In order to achieve the above object, the present invention provides a magazine type charging apparatus in which a battery required for charging is stored in a storage position, and a charged battery is transferred to the storage position and can be taken out from the storage position. And
A rotating table,
A driving device for rotating the rotary table,
A charging stand provided on the turntable and on which the battery is mounted,
A device-side charging connector provided on the charging stand and engaged with the battery-side connector of the battery;
With
The charging stand has a charging tray formed with a connector hole through which the device-side charging connector is passed,
A slide mechanism for displacing the charging tray in the front-rear direction,
It is characterized by having.

  Thus, in the present invention, the charging tray can slide in the front-back direction. Therefore, before the battery is placed on the charging tray, the position of the connector hole formed in the charging tray may not correspond to the position of the device-side charging connector. By doing so, even when the user places the battery that needs charging on the charging stand in an incorrect posture, the bottom surface of the battery does not contact the device-side charging connector. Therefore, it is possible to prevent the device-side charging connector from being damaged.

  When charging a battery that requires charging, the user places the battery on the charging tray and then slides the charging tray toward the device-side charging connector so that the position of the connector hole matches the position of the device-side charging connector. Just do it. Thus, the battery can be charged.

  Preferably, the slide mechanism is configured to include a foldable roller that contacts the bottom surface of the charging tray from below. This is because the sliding of the charging tray is assisted by the retractable roller, so that the charging tray can be easily slid. In addition, even if the user accidentally drops the battery on the charging tray, the impact acting on the roller is reduced because the retractable roller falls down. This protects the roller.

  The charging stand has a back plate extending along one side surface of the battery, and the back plate is provided with a judging projection, and the battery has an entrance of the judging projection at a position higher than the upper surface of the battery. Preferably, it is provided.

  With this configuration, it is possible to raise the device-side charging connector after the determination protrusion has entered the entrance formed in the battery. In other words, when the judging projection does not enter the entrance, the device-side charging connector keeps the lowered position. That is, only when the battery is placed on the charging tray with the end face on the side where the entrance is formed facing the projection for determination, the device-side charging connector rises under the action of the elevating mechanism and the battery-side charging is performed. Engage with connector. Then, the battery is charged by this engagement.

  In short, when the user places a battery that needs charging on the charging tray in an incorrect posture, for example, the closing portion may contact the judging projection and slide the charging tray further to the back plate side. become unable. In this situation, the device-side charging connector does not rise. For this reason, it can be avoided that the device side charging connector abuts on the bottom surface of the battery and is damaged.

  Moreover, if the device-side charging connector rises after the judging projection has entered the entrance of the battery in the normal posture, the battery is pressed from below. For this reason, an insertion load reaction force acts on the judging projection, so that the battery is firmly fixed. That is, rattling of the battery is suppressed. For this reason, the concern that the engagement between the device-side charging connector and the battery-side charging connector is released is eliminated.

  Further, it is preferable to provide a lock mechanism for positioning and fixing the charging tray when the charging tray slides and the position of the connector hole corresponds to the position of the device-side charging connector.

  The lock mechanism positions and fixes (locks) the charging tray when the device-side charging connector is raised and passed through the connector hole. This prevents the charging tray from moving during charging of the battery. Further, the state in which the device-side charging connector is raised and engaged with the battery-side charging connector is maintained. That is, the engagement between the device-side charging connector and the battery-side charging connector is prevented from being released during charging.

  According to the present invention, a charging tray provided on a charging stand of a magazine type charging device and on which a battery is placed can be slid in the front-rear direction. Therefore, before the battery is placed on the charging tray, the charging tray can be set to a position where the connector hole formed in the charging tray does not correspond to the position of the device-side charging connector. Therefore, even when the user places the battery on the charging stand in an incorrect posture, the bottom surface of the battery does not come into contact with the device-side charging connector, thereby avoiding damage to the device-side charging connector. be able to.

  When the user charges a battery that needs charging, the user places the battery on the charging tray and then slides the charging tray toward the device-side charging connector so that the position of the connector hole corresponds to the position of the device-side charging connector. Thus, the battery can be easily charged.

  Hereinafter, preferred embodiments of a magazine-type charging device according to the present invention will be described in detail with reference to the accompanying drawings.

  First, the battery 10 shown in FIGS. 1A and 1B will be described. The battery 10 has a vertically long, substantially rectangular parallelepiped shape, and is used, for example, as a driving power supply source for an electric motorcycle EB (see FIG. 21). The upper surface of the battery 10 has an arch portion 12 (second handle portion) that is bent at both ends in the longitudinal direction and continues to the upper surface to form an arch shape, and a tab-shaped protrusion whose upper edge is curved in an arc shape. The portions 14 (projections) are provided so as to face each other. The distance H2 between the upper end of the tab-shaped protrusion 14 and the bottom surface of the battery 10 is set larger than the distance H1 between the lower end of the arch portion 12 and the bottom surface of the battery 10. The protruding height of the tab-shaped protruding portion 14 and the protruding height of the arch portion 12 are substantially equal.

  A gripping bar 16 (first handle) is bridged from the upper end of the arch 12 to the upper end of the tab-shaped protrusion 14. That is, the gripping bar 16 extends in a direction substantially perpendicular to the extending direction of the arch portion 12. Here, since both upper ends of the arch portion 12 and the tab-shaped protrusion 14 protrude from the upper surface of the battery 10, the gripping bar 16 is separated from the upper surface of the battery 10. Therefore, a gripping clearance 18 is formed between the gripping bar 16 and the upper surface of the battery 10. The user can insert the hand (finger) into the gripping clearance 18 to grip the gripping bar 16.

  An entrance 20 opens between the arch 12 and the upper surface of the battery 10. A determination projection 108 (see FIGS. 6 and 7) described below enters the entrance 20. The entrance 20 is connected to the gripping clearance 18. On the other hand, the tab-shaped projection 14 has no opening. That is, the space between the tab-shaped protrusion 14 and the upper surface of the battery 10 is a closed portion.

  As shown in FIGS. 1A, 1B and 2, the battery 10 is provided with a battery-side charging connector 22 on the bottom surface where the arch portion 12 (entrance 20) is provided. The battery-side charging connector 22 is engaged with a device-side charging connector 112 (see FIG. 7) described later, so that the lower charger 52a or the upper charger 52b (see FIG. 4) and the battery 10 are connected to both connectors. The battery is electrically connected through the terminals 22 and 112 to be charged. The battery-side charging connector 22 includes a plurality of plate-shaped terminal entry recesses 24 and two rod entry recesses 26 sandwiching the plate-shaped terminal entry recesses 24 (see FIG. 2).

  When the battery 10 configured as described above is viewed in a plan view, its shape is substantially square or substantially rectangular (particularly, see FIG. 8). In this case, the space on the lower rotary table 54a can be used more effectively than when the shape of the battery 10 in a plan view is another shape.

  Next, the magazine type charging device will be described. FIG. 3 is a schematic overall perspective view of the magazine-type charging device 30. This magazine type charging device 30 has two unit magazines arranged (laminated) in the vertical direction, that is, a first unit magazine 32a and a second unit magazine 32b, and the first unit magazine 32a, the second unit magazine 32b, and the second unit magazine 32b. The unit magazine 32 b is accommodated in one casing 34. Each of the first unit magazine 32a and the second unit magazine 32b can accommodate four batteries 10, and a first accommodation position 36a for accommodating the battery 10 in the first unit magazine 32a, a second unit A first opening / closing shutter 38a and a second opening / closing shutter 38b as opening / closing shutters are provided at a second housing position 36b for housing the magazine 32b. As is understood from FIG. 3, the first accommodation position 36a and the second accommodation position 36b are offset from each other in plan view. The first storage position 36a and the second storage position 36b are also the take-out positions for taking out the battery 10, which will be described later.

  Further, a receiver (communication means) not shown is mounted on the casing 34. The receiver receives a signal transmitted from a smartphone or an RF key owned by the user or an electric motorcycle EB (see FIG. 21). The control device 60 (see FIG. 4) provided in the casing 34 recognizes that the receiver has received this signal, and performs subsequent control.

  FIG. 4 schematically shows the magazine type charging device 30 in which the casing 34 is not shown. The lower base plate 50a constituting the first unit magazine 32a has a lower charger 52a for charging the battery 10 mounted on the first unit magazine 32a, and a lower charger 52 for rotating the lower rotary table 54a. The driving motor 56a is provided so as to be close to each other. On the other hand, on the middle base plate 50b constituting the second unit magazine 32b, an upper-stage drive motor 56b for rotating the upper-stage rotary table 54b is provided. The first unit magazine 32a and the second unit magazine 32b are partitioned by the middle base plate 50b.

  As can be understood from FIGS. 3 and 4, the first unit magazine 32a and the second unit magazine 32b are vertically stacked, and the lower rotary table 54a and the upper rotary table 54b are offset from each other. The lower charger 52a, the lower drive motor 56a, and the upper drive motor 56b are arranged in the space created by this offset arrangement. For this reason, the occupied area per magazine charging device 30 is reduced.

  The lower drive motor 56a is arranged on the side of the lower turntable 54a, and the upper drive motor 56b is arranged on the side of the upper turntable 54b. For this reason, the height positions of the lower rotary table 54a and the upper rotary table 54b are not restricted by the heights of the lower drive motor 56a and the upper drive motor 56b. In other words, the lower rotary table 54a and the upper rotary table 54b can be arranged at a height that facilitates insertion and removal of the battery 10.

  Above the second unit magazine 32b, an upper charger 52b for charging the battery 10 mounted on the second unit magazine 32b, and an upper base plate 50c provided with the control device 60 are provided. .

  Next, the first unit magazine 32a will be described in detail. FIG. 5 is a schematic exploded perspective view of the first unit magazine 32a. In the first unit magazine 32a, as the lower rotary table 54a performs index rotation on the lower base plate 50a, the charging unit 90 on which the battery 10 is mounted is integrally index rotated. The first opening / closing shutter 38a covers a part of the charging unit 90 in a first storage position 36a (see FIG. 3) so as to be exposed. In other words, the charging section 90 located at the first storage position 36a is exposed to the outside of the casing 34 when the first opening / closing shutter 38a is opened.

  The charging unit 90 will be described. FIG. 6 and FIG. 7 are schematic perspective views of a main part of the charging unit 90 constituting the first unit magazine 32a. The charging unit 90 includes a turntable 92 that rotates integrally with the lower rotary table 54a, and four charging stands 100 provided on the turntable 92. The charging stands 100 are partitioned by a back plate 102, and each charging stand 100 is provided with a charging tray 104. A part of the charging stand 100 is passed through a through hole 105 formed in the turntable 92, and rotates integrally with the lower rotary table 54a and the turntable 92 (see FIG. 5).

  A proximity sensor 106 is provided on the back plate 102, and a substantially U-shaped determination projection 108 is formed above the proximity sensor 106. A part of the back plate 102 projects from the lower surface of the turntable 92 and is connected to the lower turntable 54a. That is, the back plate 102 is supported by the lower rotary table 54a in a standing posture. Therefore, the back plate 102 also rotates integrally with the lower rotary table 54a and the rotary disk 92.

  The inner end face of the backboard 102 is arranged at a position offset from the end face of another backboard 102. Therefore, when the four back plates 102 are combined with each other, a square pillar-shaped hollow portion 802 is formed at the center of the combination.

  As shown in FIG. 8, one battery 10 can be placed on one charging stand 100. As shown in FIG. 8, the four batteries 10 are slightly offset from the completely opposed positions in plan view. Here, in order to clearly distinguish the batteries 10, the four batteries 10 in FIG. 8 are referred to as a first battery 10a, a second battery 10b, a third battery 10c, and a fourth battery 10d. The three batteries 10c face each other, and the second battery 10b and the fourth battery 10d face each other.

  When a left virtual line L1 contacting the left corners of the first battery 10a and the third battery 10c facing each other and a right virtual line L2 contacting the right corners are drawn, the left virtual line L1 becomes the second virtual line L1. Crosses the battery 10b. Similarly, the right virtual line L2 crosses the fourth battery 10d.

  Furthermore, the second battery 10b and the third battery 10c adjacent to each other in the horizontal direction have different upper end positions, and the first battery 10a and the second battery 10b adjacent to each other in the vertical direction have different left end positions. Here, the above “left”, “right” and “up” represent directions when the user looks at the charging unit 90 in a plan view, and do not mean rightward, leftward or upward of the battery 10.

  In this way, the batteries 10 facing each other and the batteries 10 adjacent to each other are placed on the charging stand 100 in the casing 34 so that they are offset from each other. Therefore, the space on the lower rotary table 54a can be used more effectively than when the four batteries 10 are arranged at the apexes of a square and completely opposed to each other.

  As can be understood from FIG. 8, the adjacent batteries 10, that is, the first battery 10a and the second battery 10b, the second battery 10b and the third battery 10c, the third battery 10c and the fourth battery 10d, In the four batteries 10d and the first battery 10a, the extending directions of the gripping bars 16 are substantially orthogonal to each other.

  The charging tray 104 shown in FIGS. 6 and 7 is slidable in the direction of arrow A, that is, in the front and rear directions (A1 direction and A2 direction) in front view. Note that the direction of arrow A in the following drawings coincides with the direction of arrow A in FIGS. 6 and 7. Hereinafter, in accordance with the sliding direction of the charging tray 104, the side separated from the device-side charging connector 112 (direction A1) may be referred to as “front”, and the side adjacent thereto (direction A2) may be referred to as “rear”. In the following description, “front end” indicates an end on the A1 side, and “rear end” indicates an end on the A2 side.

  The charging tray 104 is located at the forefront when the battery 10 is not placed at the first storage position 36a. FIG. 6 shows a state where the charging tray 104 is slightly biased forward. Then, after the battery 10 is placed, the charging tray 104 is slid rearward (A2 side). When the position of the connector hole 110 corresponds to the position of the device-side charging connector 112 at the time of sliding backward, the device-side charging connector 112 rises and passes through the connector hole 110 as shown in FIG.

  Here, in the charging stand 100 other than the first accommodating position 36a, the charging tray 104 is located at the rearmost position (A2 side), the device side charging connector 112 is passed through the connector hole 110, and the battery 10 is loaded. Is placed. Therefore, the charging tray 104 other than the first storage position 36a does not slide forward.

  The charging stand 100 includes a support plate 200 that faces the charging tray 104 with the insertion hole 105 interposed therebetween. That is, the support board 200 is disposed below the charging tray 104. The support board 200 is positioned and fixed on the upper surface of the lower rotary table 54a (see FIG. 5).

  As shown in detail in FIG. 9, the device-side charging connector 112 is arranged on the support board 200 so as to be able to move up and down. The device-side charging connector 112 has a plate-like terminal 114 that enters or leaves the plate-like terminal entry recess 24, and two engagement rods 116 that sandwich the plate-like terminal 114. The engagement rod 116 enters or leaves the rod entry recess 26.

  The device-side charging connector 112 includes two guided portions 120 provided outside the engagement rod 116 (see FIG. 13). A guide hole 122 is formed through the guided portion 120 along the vertical direction. A guide rod 526 described later is slidably inserted into the guide hole 122.

  On the support board 200, a slide mechanism 300 that allows the charging tray 104 to slide back and forth, a lock mechanism 400 that positions and fixes the charging tray 104 that slides backward, and an elevating mechanism that moves the device-side charging connector 112 up and down. 500 are provided.

  The sliding mechanism 300 includes a plurality of foldable rollers 302 on which the charging tray 104 slides, a movable plate 304 connected to the lower surface of the charging tray 104, and two moving rollers 304 provided on the lower surface of the charging tray 104. A hook plate 305. The retractable roller 302 is provided at a position sandwiching a plurality of shock absorbing springs 306 erected on the support board 200.

  The slide mechanism 300 further has a spring fixing portion 308 erected on the support board 200. A tray discharge spring 310 (elastic member) is stretched between the spring fixing portion 308 and the hook plate 305. That is, the front end of the tray discharge spring 310 that is separated from the device-side charging connector 112 is engaged with the spring fixing portion 308 that is positioned and fixed. On the other hand, the rear end near the device-side charging connector 112 is hooked on a hooking plate 305 that is displaced together with the charging tray 104.

  As shown in FIG. 10, below the moving plate 304, two columnar legs 312 are provided so as to hang down. An elliptical plate 314 having a substantially elliptical shape is bridged between the legs 312.

  As shown in FIGS. 9 and 10, the lock mechanism 400 has a rack slide 404 that can be displaced along a set of rack guide rails 402 provided on the support board 200, and is attached to the rack slide 404. A claw member 406 supported by the displacement plate 405 and displaced integrally with the rack slide 404 and the displacement plate 405, a cam member 408, and a snatch lock 410 are provided.

  The rack guide rail 402 therein extends along the direction of arrow A, and the rack slide 404, the displacement plate 405, and the claw member 406 are displaced so as to approach or separate from the device-side charging connector 112. (Retreat or move forward). FIG. 9 shows a state in which the rack slide 404, the displacement plate 405, and the claw member 406 are closest to the device-side charging connector 112, that is, a state in which the rack slide 404, the displacement plate 405, and the claw member 406 are located at the rearmost position. At this time, the charging tray 104 is also retracted to the back plate 102 side (A2 direction side) (see FIG. 7). The device-side charging connector 112 is located at the bottom dead center.

  The claw member 406 has a first cam portion 412 protruding so as to be substantially perpendicular to the direction of arrow A. An insertion hole (not shown) is formed at one corner of the rear end of the claw member 406, and the first rotation shaft 414 is fitted into the insertion hole. The claw member 406 is connected to the displacement plate 405 via the first rotation shaft 414, and can rotate around the first rotation shaft 414. Further, one end of the first return spring 416 is hooked at another corner of the claw member 406 facing the one corner.

  One of the rack guide rails 402 is provided with a flat plate-shaped spring retaining portion 418 so as to protrude in a direction orthogonal to the longitudinal direction. The other end of the first return spring 416 is hooked on the spring hook 418. That is, the first return spring 416 urges the claw member 406 toward the spring engaging portion 418 (the front A1 side).

  A set of cam guides extending in a direction substantially perpendicular to the longitudinal direction (the direction of arrow A) of the rack guide rails 402 is provided at the rear end of the rack guide rail 402 near the device-side charging connector 112. The rail 420 is supported. The upper end of the cam member 408 is slidably sandwiched between cam guide rails 420.

  The cam member 408 is substantially orthogonal to the displacement direction of the rack slide 404 while being guided by the cam guide rail 420 as the rack slide 404 is displaced toward or away from the device-side charging connector 112. Displace in the direction. This will be described later.

  The cam member 408 has a second cam portion 424 that cooperates with the first cam portion 412 of the pawl member 406. The second cam portion 424 faces the first cam portion 412.

  The snatch lock 410 includes a link member 430, a hook member 432, and a backup plate 434 that rotatably supports the link member 430 and the hook member 432.

  One end of the cam member 408 is connected to a rear end of the link member 430 via a connection shaft 436. The front end of the link member 430 is rotatably connected to the backup plate 434 via a second rotation shaft 440 (particularly, see FIG. 12). Therefore, when the cam member 408 is displaced along the cam guide rail 420, as shown in FIGS. 11 and 12, the link member 430 changes its posture.

  The link member 430 has a first raised portion 442 protruding toward the hook member 432 at a position intermediate the connection shaft 436 and the second rotation shaft 440.

  The hook member 432 is rotatably supported by the backup plate 434 via a third rotation shaft 444 provided at a substantially central portion thereof.

  The hook member 432 is provided with a second raised portion 446 protruding toward the first raised portion 442 of the link member 430. The first raised portion 442 and the second raised portion 446 can move over each other when the link member 430 and the hook member 432 rotate (see FIGS. 10 to 12).

  At the front end of the hook member 432, a hook portion 450 is formed in which a portion facing the link member 430 is cut out in a U-shape. The leg 312 of the movable plate 304 is restrained by the hook 450 when the link member 430 and the hook member 432 are in a predetermined positional relationship. As will be described later, this constraint positions and fixes the charging tray 104 to the rearmost position. On the other hand, when the rack slide 404 is displaced (retreats) toward the device-side charging connector 112 and the pawl member 406 presses the cam member 408, the hook member 432 rotates as shown in FIGS. . By this rotation, the leg 312 of the movable plate 304 is released from the hook 450.

  A second return spring 452 is stretched between the hook member 432 and the link member 430. One end of the second return spring 452 is locked to the rear end of the hook member 432, and the other end of the second return spring 452 is locked to a portion of the link member 430 between the connection shaft 436 and the first raised portion 442. Is done. The second return spring 452 urges the rear end of the hook member 432 toward the link member 430 to pull it.

  As shown in FIG. 13, the lifting mechanism 500 that raises and lowers the device-side charging connector 112 includes a lifting motor 502, a worm 504, a worm gear 506, a rack-side gear 508 having flat teeth, a rack slide 404, And a link portion 510 for connecting the charging connector 112. The worm 504 is provided on the rotation shaft of the elevating motor 502 and meshes with the worm gear 506. The worm gear 506 and the rack-side gear 508 are connected via a transmission shaft 512, and the rack-side gear 508 meshes with a tooth portion (not shown) provided on the lower surface of the rack slide 404.

  The link portion 510 has a first shaft 514 provided at the rear end of the rack slide 404 and extending in a direction substantially orthogonal to the arrow A direction, and a long hole 516 through which the first shaft 514 is formed at the upper end thereof. A pair of arm members 518 extending below the device-side charging connector 112. The arm member 518 extends to incline from the A2 side to the A1 side, and then bends to extend to incline from the A1 side to the A2 side. The second shaft 520 is passed through a bending point between the pair of arm members 518.

  Further, the rear end of the arm member 518 is connected to a bearing portion 522 provided near the guided portion 120. That is, the bearing portion 522 is formed with the elongated hole 524 extending along the arrow A direction. A third shaft 525 is connected to the rear ends of the arm members 518, and the third shaft 525 passes through the elongated holes 524.

  When the elevating motor 502 is energized, the worm 504, the worm gear 506, the transmission shaft 512, and the rack gear 508 rotate. Therefore, the rack slide 404 is displaced along the direction A1 in FIG. As will be described later, following this displacement, the arm member 518 rotates as shown in FIGS. 14 shows a state in which the device side charging connector 112 is located at the bottom dead center, and FIG. 15 shows a state in which the device side charging connector 112 is located at the top dead center.

  The lifting mechanism 500 further includes a guide rod 526 inserted into the guide hole 122 of the guided portion 120 of the device-side charging connector 112. The guide rod 526 guides the device-side charging connector 112 that moves up or down.

  When the charging tray 104 is not restrained by the snatch lock 410, the tray discharging spring 310 extends and urges the charging tray 104 in the A1 direction.

  Next, the lower rotary table 54a provided below the charging unit 90 will be described.

  As shown in FIG. 17, a phase holding cylinder 600 (positioning mechanism) for holding the position of the lower rotary table 54a is provided on the lower base plate 50a. The phase holding cylinder 600 has an advancing / retracting rod 602, and when the advancing / retracting rod 602 advances, it enters an engaging recess 604 formed on a side peripheral wall of the lower rotary table 54a. As a result, the rotation of the lower rotary table 54a is prevented and maintained at that phase.

  The lower base plate 50a is further provided with a first cam follower 606 receiving a heavy load, a second cam follower 608 receiving a light load, a third cam follower 610 for centering the lower rotary table 54a, and an interlock switch 612. . The lower rotary table 54a is supported by the first cam follower 606, the second cam follower 608, and the third cam follower 610, so that it can be positioned slightly above the lower base plate 50a.

  As shown in FIG. 16, the lower rotary table 54 a is configured such that a ring body 614 having a slightly larger thickness than the disc-shaped body 613 is fitted to a side peripheral wall of the disc-shaped body 613. The first cam follower 606 and the second cam follower 608 are in sliding contact with the lower surface of the disc-shaped body 613. On the other hand, the third cam follower 610 slides in a sliding groove 615 formed in the inner peripheral wall of the ring body 614. A winding groove (not shown) around which the timing belt 616 is wound is formed on the outer peripheral wall of the ring body 614.

  The engagement recess 604 and the latch groove 620 are formed on the outer peripheral wall of the ring body 614. The engagement recess 604 and the latch groove 620 are arranged at every 90 °.

  As shown in FIG. 18, a bearing 622 may be provided on the lower base plate 50a instead of the third cam follower 610. In this case, a bearing receiver 624 is provided on the lower rotary table 54a (the disc-shaped body 613), and the bearing 622 and the bearing receiver 624 can center the lower rotary table 54a. Therefore, there is an advantage that the number of parts is reduced. Therefore, there is no particular need to provide the third cam follower 610.

  The timing belt 616 is stretched over a pulley 630 that is fitted around the rotation shaft of the lower drive motor 56a. Accordingly, the pulley 630 rotates in accordance with the rotation of the rotating shaft of the lower drive motor 56a, the timing belt 616 rotates, and the lower rotary table 54a rotates. The interlock switch 612 detects the latch groove 620 of the lower rotary table 54a that rotates in this way.

  As shown in FIG. 19, the first opening / closing shutter 38a has a shutter body 700. The shutter body 700 rotates under the action of a shutter opening / closing motor 702. The shutter body 700 has a fan-shaped first portion 704 that covers the upper surface side of the battery 10 (the arch portion 12, the tab-shaped protrusion 14, and the gripping bar 16), and a second portion that covers the side surface of the battery 10. 706, and a third portion 708 interposed between the first portion 704 and the second portion 706 and connected to bend. Further, an annular driving force transmitting portion 710 is provided at the center of the first portion 704, and a shutter bearing holder 712 and a shutter bearing 714 are provided in the driving force transmitting portion 710.

  As shown in FIG. 20, the shutter body 700 includes a fourth portion 716 and a fifth portion 718 each having a different radius connecting the center of the shutter bearing 714 and the outer periphery of the second portion 706 in plan view. It further has a sixth part 720 interposed between the fourth part 716 and the fifth part 718.

  The shutter bearing 714 is provided at a position higher than the upper end (arch 12, tab-shaped protrusion 14, and gripping bar 16) of the battery 10 placed on the charging stand 100. This prevents the battery 10 from interfering with the shutter bearing 714.

  The shutter opening / closing motor 702 is provided on the side of the shutter bearing 714 and outside the outer periphery of the lower rotary table 54a (see FIG. 20). That is, the shutter opening / closing motor 702 is not disposed at a position that overlaps below or above the lower rotary table 54a. For this reason, the height of the magazine type charging device 30 can be reduced, and downsizing can be achieved.

  Outside the shutter bearing 714, a large pulley 722 (or large sprocket) as a transmission mechanism is provided. An opening / closing belt 726 (or opening / closing chain) is wound around the large pulley 722 and a small pulley 724 (or small sprocket) provided on the rotation shaft of the shutter opening / closing motor 702. It is preferable that the large pulley 722 be provided with a torque limiter 728.

  A power transmission cable 800 (cable) is electrically connected to the device-side charging connector 112. The power transmission cable 800 is passed through a through hole 801 (see FIGS. 5, 16 and 17) formed at the center of the lower rotary table 54a, and is placed on the charging stand 100 above the center. From a position higher than the upper end of the battery 10, the battery 10 is passed through a square pillar-shaped hollow portion 802 (see FIGS. 6 and 7) formed by combining the back plates 102. In addition, the power transmission cables 800 are bundled together by the convergence band 804, thereby preventing the torsion from propagating to the lower charger 52a.

  The second unit magazine 32b is configured according to the first unit magazine 32a. For this reason, the same components are denoted by the same reference numerals, and detailed description thereof will be omitted. In the second unit magazine 32b, a member corresponding to the lower base plate 50a of the first unit magazine 32a is the middle base plate 50b.

  The magazine-type charging device 30 according to the present embodiment is basically configured as described above. Next, its operation and effect will be described in relation to a method of fixing the battery 10. In the following, a case where two batteries 10 are replaced at the same time is exemplified, but it is needless to say that only one battery 10 may be replaced.

  The battery 10 is used, for example, as a drive source of the electric motorcycle EB shown in FIG. The battery 10 used for traveling of the electric motorcycle EB and having a reduced discharge capacity is charged by the magazine charging device 30 described above.

  The magazine type charging device 30 is installed at a predetermined charging station ST provided outside. The user only needs to approach the magazine-type charging device 30 while riding on the electric motorcycle EB or on foot. At this point, both the first opening / closing shutter 38a and the second opening / closing shutter 38b are in the closed state.

  As described above, the transmitter is provided on the electric motorcycle EB or the smartphone or RF key possessed by the user. The receiver provided on the casing 34 of the magazine type charging device 30 receives a signal transmitted by the transmitter. The control device 60, which recognizes that the receiver has received the signal for a predetermined time, issues a command signal to "open the shutter" to the shutter opening / closing motor 702 (see FIG. 19). The control device 60 keeps the shutters 38a and 38b open when the receiver receives a signal from the transmitter for a predetermined time.

  In some cases, the electric motorcycle EB or the like only passes through the charging station ST. At this time, even if the receiver receives the signal from the transmitter, the receiving period is short. In this case, control is performed so that the shutter body 700 does not rotate.

  The shutter opening / closing motor 702 is energized based on a command signal “open shutter”, and the small pulley 724 rotates and the opening / closing belt 726 rotates. As a result, the large pulley 722 serving as the transmission mechanism rotates, and the shutter body 700 rotates about the driving force transmission unit 710 provided with the large pulley 722 (see FIGS. 19 and 20). Accordingly, the first opening / closing shutter 38a and the second opening / closing shutter 38b are opened. Thereby, each charging part 90 located at the first storage position 36a and the second storage position 36b, and eventually the charging stand 100, is exposed to the outside of the casing 34.

  As described above, according to the present embodiment, since the shutter body 700 automatically rotates, there is no need for the user to rotate the shutter body 700. Therefore, the charged battery 10 can be taken out only by approaching the magazine type charging device 30, and the used battery 10 or the battery 10 having an insufficient charged amount can be set in the magazine type charging device 30.

  As shown in FIG. 20, the shutter body 700 includes a fourth portion 716 and a fifth portion 718 having different radial lengths connecting the center of the shutter bearing 714 and the outer periphery of the second portion 706 in plan view. Having. For this reason, the length in the depth direction required when the shutter body 700 changes from the closed state to the open state is reduced. Accordingly, the installation area per magazine type charging device 30 can be reduced.

  An object such as a user's hand may come into contact with the shutter body 700 while the shutter body 700 is being opened. At this time, torque acts on the shutter body 700. When the large pulley 722 is provided with the torque limiter 728, the control device 60 detects that the torque has been applied via the torque limiter 728, and stops the opening operation of the shutter body 700. Therefore, an excessive load is prevented from acting on the shutter body 700 and the shutter bearing 714, and an object is prevented from being caught in the shutter body 700. Instead of stopping the opening operation, the shutter body 700 may be switched from the opening operation to the closing operation.

  After the first opening / closing shutter 38a and the second opening / closing shutter 38b are opened, the user maintains a state in which the charging stands 100 of the first unit magazine 32a and the second unit magazine 32b are slid forward. The battery 10 that needs to be charged is placed on the charging tray 104 with the entrance 20 facing the back plate 102 (the judging projection 108). That is, the battery 10 requiring charging is inserted into the casing 34 from the first storage position 36a and the second storage position 36b shown in FIG. Since the first storage position 36a and the second storage position 36b are offset from each other, the charged battery 10 is taken out from each of the charging units 100 of the first unit magazine 32a and the second unit magazine 32b, and each of the charging units 100 The insertion of the battery 10 that needs to be charged into the battery becomes extremely easy.

  When placing the battery 10 that needs charging on the charging tray 104, it is assumed that the user accidentally releases his / her hand from the gripping bar 16. In this case, the impact absorbing spring 306 (see FIG. 9) and the first cam follower 606 (see FIGS. 17 and 18) receive the load of the dropped battery 10, and the retractable roller 302 falls down. Therefore, damage to the charging tray 104, the lock mechanism 400, the slide mechanism 300 including the roller main body of the retractable roller 302, and the like can be avoided.

  When the battery 10 requiring charging is placed on the charging tray 104, the device-side charging connector 112 is lowered and positioned below the lower rotary table 54a (see FIG. 6). Therefore, for example, even when the user mistakenly places the battery 10 on the charging tray 104 such that the tab-shaped protrusion 14 faces the back plate 102 (the judging projection 108), the battery-side charging connector 22 is The non-existent bottom surface is effectively prevented from contacting the device-side charging connector 112. Therefore, the device-side charging connector 112 is prevented from being damaged due to this contact.

  After placing the battery 10 on the charging tray 104, the user presses the charging tray 104 toward the back plate 102. In other words, the charging tray 104 is slid together with the battery 10 toward the back plate 102 (the rear direction A2). With this slide, the latch plate 305 is displaced rearward integrally with the charging tray 104, so that the tray discharging spring 310 which has been contracted up to that point is extended. When the user slides the charging tray 104 to the rearmost position, the charging tray 104 is locked at that position by the snatch lock 410. The operation of the snatch lock 410 at this time will be further described below.

  In the state before the charging tray 104 is slid backward, in the snatch lock 410, as shown in FIG. 12, the hook portion 450 of the hook member 432 is separated from the front end of the link member 430. At this time, the second raised portion 446 is located ahead of the first raised portion 442 and is separated from the first raised portion 442.

  When the charging tray 104 is slid rearward, the rear leg 312 presses the inner wall on the rear end side of the hook 450. Due to this pressing, the hook member 432 rotates around the third rotation shaft 444, the hook portion 450 approaches the front end of the link member 430, and the second return spring 452 gradually extends.

  When the amount of rotation of the hook member 432 increases, the second protrusion 446 engages with the first protrusion 442 and presses it.

  Eventually, when the second raised portion 446 gets over the first raised portion 442, the hook member 432 draws the link member 430 via the second return spring 452. As a result, the posture of the link member 430, that is, the direction of inclination of the link member 430 with respect to the direction A changes, and the cam member 408 is displaced toward the claw member 406. Then, the rotation of the hook member 432 and the link member 430 stops.

  When the rotation of the hook member 432 is stopped, the opening of the hook portion 450 faces the link member 430. That is, the hook 450 closes (see FIGS. 9 and 10). In this state, the second raised portion 446 is located behind the first raised portion 442. In this state, even if the charging tray 104 is slid forward, the action of the second ridge 446 pressing the first ridge 442 forces the hook member 432 and the link member 430 to move excessively. The charging tray 104 does not slide. Therefore, the leg 312 is restrained by the hook 450, and the charging tray 104 is locked at a position close to the device-side charging connector 112.

  The judging projection 108 enters the entrance 20 of the battery 10 slid toward the back plate 102. In response to this approach, the proximity sensor 106 provided on the back plate 102 detects the presence of the battery 10. Control device 60 receiving this detection signal recognizes that "battery 10 has moved to the normal charging position."

  On the other hand, when the tab-shaped protrusion 14 faces the back plate 102 because the battery 10 is erroneously inserted, the tab-shaped protrusion 14 comes into contact with the judgment protrusion 108. Since H2> H1 as shown in FIG. 1A, the upper end of the tab-shaped protrusion 14 is higher than the lower end of the arch 12 (the bottom of the entrance 20), and the tab-shaped protrusion 14 is a closing part. That's why. Therefore, the battery 10 stops and the charging tray 104 cannot be slid further backward. In this case, the proximity sensor 106 does not detect the presence of the battery 10 and the control device 60 does not recognize that "the battery 10 has moved to the regular charging position". By visually recognizing this situation, the user can recognize that the direction (posture) of the battery 10 has been erroneously inserted. In this case, the battery 10 may be taken out and put back in a proper posture.

  When recognizing that “the battery 10 has moved to the regular charging position”, the control device 60 energizes the elevating motor 502 (see FIGS. 9 and 13) according to the command signal. Accordingly, the worm 504 rotates, and the worm gear 506, the transmission shaft 512, and the rack-side gear 508 rotate. As a result, the rack slide 404 is displaced away from the device-side charging connector 112. That is, the rack slide 404 advances in the A1 direction.

  As the rack slide 404 advances, the first shaft 514 provided at the rear end of the rack slide 404 also integrally advances in the A1 direction. Therefore, the upper end of the arm member 518 through which the first shaft 514 is passed through the elongated hole 516 is pulled forward (A1 direction). Thereby, the lower end of the arm member 518 rises. As a result, the arm member 518 rotates from the posture shown in FIG. 14 to the posture shown in FIG. Since the guided portion 120 is restrained by the guide rod 526, the device-side charging connector 112 rises vertically upward following the rotation of the arm member 518.

  Here, a description will be given of a case where the cam member 408 holds the position where the cam member 408 is displaced toward the claw member 406 even if the rack slide 404 advances, and the lock of the charging tray 104 described later is not released. When the rack slide 404 advances, the displacement plate 405 and the claw member 406 advance integrally. At this time, as shown in FIG. 22, the tip of the first cam portion 412 of the claw member 406 which advances is interfered with the tip of the second cam portion 424 of the cam member 408.

  When the rack slide 404 further moves forward, the first cam portion 412 is pressed from the second cam portion 424 because the tip thereof interferes with the tip of the second cam portion 424 of the cam member 408. The claw member 406 that has been pressed rotates around the first rotation shaft 414 so that the first cam portion 412 moves backward. At the same time, the first return spring 416 extends.

  By the above rotation, interference of the first cam portion 412 with the second cam portion 424 is avoided. When the first cam portion 412 is located forward of the second cam portion 424 with the advance of the rack slide 404, the first return spring 416 contracts, and urges the claw member 406 to the front side. As a result, the claw member 406 rotates in the opposite direction to the above and returns to the original posture. Further, further rotation of the claw member 406 in the reverse direction is restricted.

  The guided portion 120 of the device-side charging connector 112 is guided by a guide rod 526 passed through the guide hole 122 while ascending. As a result, the device side charging connector 112 rises toward the connector hole 110 side. FIG. 23 shows a state where the rack slide 404, the displacement plate 405, and the claw member 406 have advanced to the maximum.

  The device-side charging connector 112 that has risen as described above passes through the connector hole 110 of the charging tray 104 and is engaged with the battery-side charging connector 22. That is, the plate-shaped terminal 114 enters the plate-shaped terminal entry recess 24 (see FIG. 2), and the two engagement rods 116 enter the rod entry recess 26.

  The battery 10 is firmly supported on the charging stand 100 by the engagement of the device-side charging connector 112 with the battery-side charging connector 22 and the entry of the determination projection 108 into the entrance 20. In particular, the judging projection 108 applies an insertion load reaction force to the bottom of the entrance 20. Therefore, the battery 10 is prevented from being displaced or rattled, or from falling down.

  As described above, according to the present embodiment, when the battery 10 requiring charging is inserted (accommodated) into the casing 34 of the magazine-type charging device 30 from the first accommodation position 36a and the second accommodation position 36b. Only by performing a simple operation of sliding the charging tray 104 on which the battery 10 is placed toward the back plate 102, it is possible to determine whether the battery 10 is inserted in a proper posture. At the same time, damage to the device-side charging connector 112 or the battery-side charging connector 22 can be prevented, and the battery 10 can be firmly held.

  Alternatively, a warning sound may be emitted when the device-side charging connector 112 does not rise even after the user inserts the battery 10 requiring charging for a certain period of time. This allows the user to recognize whether the battery 10 that needs to be charged is inserted in an incorrect posture, or whether the device-side charging connector 112 has been raised for some reason.

  After that, the control device 60 issues a command signal to the shutter opening / closing motor 702 to rotate the small pulley 724, and rotates the opening / closing belt 726 to rotate the large pulley 722. As a result, the shutter main body 700 rotates around the driving force transmission unit 710 (see FIG. 20), and the first opening / closing shutter 38a and the second opening / closing shutter 38b are closed. This prevents the user from putting his hand in the casing 34 and the like.

  As described above, in the present embodiment, the battery 10 and the charging stand 100 are protected by the casing 34, the first opening / closing shutter 38a, and the second opening / closing shutter 38b. Therefore, even when outdoors, the battery 10 and the charging stand 100 are prevented from coming into contact with rainwater or dust. That is, the magazine-type charging device 30 can be suitably used outdoors.

  Next, the control device 60 energizes the lower drive motor 56a and the upper drive motor 56b. Accordingly, as the timing belt 616 rotates, the lower rotary table 54a and the upper rotary table 54b rotate. FIG. 24 shows the flow of the rotation operation at this time, taking the first unit magazine 32a as an example. Note that “empty”, “small”, “medium” and “full” in FIG. 24 respectively indicate the battery 10 that is difficult to discharge any more and needs to be charged, the charging is started, and the discharge capacity is recovered. A battery 10 being charged, a battery 10 being charged after a certain amount of time has elapsed since the start of charging, and a charged battery 10 whose charge capacity has been greatly recovered, and a fully charged battery 10 having a charge capacity fully recovered from the discharge capacity. That is, “empty” does not mean that the battery 10 does not exist.

  When the battery 10 that needs to be charged (“empty”) is inserted into the casing 34 from the first storage position 36a as described above, the lower rotary table 54a rotates 90 ° clockwise (rightward). Rotate. As a result, the charging section 90 including the turntable 92 also rotates integrally with the index, so that the fully charged battery 10 is transferred to the first storage position 36a.

  The phase of the lower rotary table 54a after the index rotation is determined by the interlock switch 612 (see FIGS. 17 and 18) detecting the position of the latch groove 620. Then, after it is determined that the lower rotary table 54a is rotating by 90 ° index, the advance / retreat rod 602 of the phase holding cylinder 600 moves forward and enters the engaging recess 604. This entry (engagement) prevents rotation of the lower rotary table 54a.

  In addition, when the lower rotary table 54a is rotated by the index, the second cam follower 608 prevents the lower rotary table 54a from rattling and the third cam follower 610 maintains the position of the rotation center.

  Of course, the upper rotary table 54b constituting the second unit magazine 32b operates in the same manner as described above.

  The control device 60, which has recognized that the lower rotary table 54a has rotated the index by 90 °, issues a command signal to the charging stand located at the first storage position 36a and the second storage position 36b to which the fully charged battery 10 has been transferred. Only the elevating motor 502 (see FIGS. 9 and 13) provided on the support plate 200 of 100 is energized. That is, the remaining three lifting / lowering motors 502 are not simultaneously energized.

  As the lifting motor 502 is energized, the worm 504 rotates in a direction opposite to the above. As the worm gear 506, the transmission shaft 512, and the rack-side gear 508 rotate following this rotation, the rack slide 404 is displaced so as to approach the device-side charging connector 112. That is, it retreats in the A2 direction.

  As the rack slide 404 retreats, the first shaft 514 integrally retreats in the A2 direction. Accordingly, the upper end of the arm member 518 is pulled rearward (A2 direction), so that the lower end of the arm member 518 is lowered. That is, the arm member 518 rotates from the posture shown in FIG. 15 to the posture shown in FIG. Following this rotation, the device-side charging connector 112 descends and separates from the battery-side charging connector 22, and is located below the lower rotary table 54a through the connector hole 110 of the charging tray 104. During the downward movement, the device-side charging connector 112 is guided by the guide rod 526.

  When the rack slide 404 retreats toward the device-side charging connector 112 as described above, the first cam portion 412 of the claw member 406 that advances integrally with the device-side charging connector 112 becomes the second cam portion 424 of the cam member 408. Press. The cam member 408 that has been pressed is displaced along the cam guide rail 420 in a direction away from the rack guide rail 402.

  Therefore, the link member 430 changes its posture in a direction away from the hook member 432, and the second raised portion 446 rides over the first raised portion 442 and is located forward (in the direction A <b> 1) of the first raised portion 442. Accordingly, the link member 430 draws the hook member 432 via the second return spring 452.

  The hook member 432 rotates around the third rotation shaft 444, and the hook portion 450 separates from the link member 430 (see FIG. 12). That is, the hook portion 450 opens.

  As a result, the leg 312 is released from the hook 450 as shown in FIG. With this release, the tray discharge spring 310 contracts, and the contracted tray discharge spring 310 urges the charging tray 104 to pull forward.

  Therefore, the charging tray 104 slides in the direction opposite to the device-side charging connector 112, that is, in the A1 direction, which is the front, integrally with the hook plate 305. FIG. 25 shows the state of the slide mechanism 300 and the lock mechanism 400 when the charging tray 104 moves forward, together with the support board 200.

  Thus, the charging tray 104 is returned to the forward position at the first storage position 36a. At this time, the charged battery 10 also moves forward integrally and separates from the back plate 102. Therefore, the entrance 20 of the battery 10 is separated from the judging projection 108 of the back plate 102.

  In the present embodiment, after the proximity sensor 106 detects that the charged battery 10 has separated from the back plate 102, a command signal is transmitted from the control device 60 to the shutter opening / closing motor 702. As a result, the small pulley 724 rotates to rotate the opening / closing belt 726, and the large pulley 722 rotates to open the first opening / closing shutter 38a and the second opening / closing shutter 38b. Thereafter, the user may take out the fully charged battery 10 transferred to the first storage position 36a and the second storage position 36b from the casing 34 and mount it on the electric motorcycle EB.

  As shown in FIG. 8, the extending directions of the gripping bars 16 of the adjacent batteries 10 are substantially orthogonal to each other. Therefore, the extending direction of the gripping bar 16 when the user takes out the fully charged battery 10 matches the extending direction of the gripping bar 16 when the battery 10 requiring charging is accommodated. Therefore, it is easy to take out the battery 10.

  As described above, the first opening / closing shutter 38a and the second opening / closing shutter 38b are opened after the charging tray 104 and the battery 10 have been transferred to the first storage position 36a and the second storage position 36b. This prevents the user from putting his / her hand into the casing 34 while the charging unit 90 is rotating the index.

  After the charged battery 10 is removed, a command signal is transmitted from the control device 60 to the shutter opening / closing motor 702, and the first opening / closing shutter 38a and the second opening / closing shutter 38b are closed. This prevents the user from touching the shutter body 700 during the removal of the battery 10. In addition, it is possible to prevent the user from putting his / her hand in the casing 34 after taking out.

  By taking out the charged battery 10 as described above, the battery 10 becomes absent at the first storage position 36a and the second storage position 36b. In this situation, power is supplied from the lower charger 52a and the upper charger 52b to the device-side charging connector 112 via the power transmission cable 800. Therefore, the charging of the three (a total of six) batteries 10 remaining in each of the first unit magazine 32a and the second unit magazine 32b progresses, and the batteries 10 that have been “empty” and need to be charged become “small”. ". Similarly, the battery 10 that was “small” becomes “medium”, and the battery 10 that was “medium” becomes “full”. In the first storage position 36a and the second storage position 36b, the battery 10 remains absent.

  The second user accommodates the battery 10 requiring charging in the casing 34 from the first accommodation position 36a and the second accommodation position 36b in the same manner as described above. Also in this case, similarly to the above, the lower rotary table 54a and the upper rotary table 54b rotate clockwise (rightward) by 90 ° index. Therefore, the lower rotary table 54a and the upper rotary table 54b have been rotated by 180 ° from the initial position.

  After the fully charged battery 10 ("full") that has reached the first storage position 36a and the second storage position 36b is taken out, this state, that is, the first storage position 36a and the second storage position as described above. At 36b, charging is performed with the battery 10 absent. As a result, “sky”, “small” and “medium” become “small”, “medium” and “full”.

  The third user accommodates the battery 10 requiring charging in the casing 34 from the first accommodation position 36a and the second accommodation position 36b in the same manner as described above. In this case, the lower rotary table 54a and the upper rotary table 54b rotate 270 ° in the counterclockwise direction (left direction). Accordingly, the index rotation of the lower rotary table 54a and the upper rotary table 54b from the initial positions is -90 degrees.

  After the fully charged battery 10 ("full") that has reached the first storage position 36a and the second storage position 36b is taken out, this state, that is, the first storage position 36a and the second storage position as described above. At 36b, the battery 10 is charged by the charging unit 90 at a position other than the first storage position 36a and the second storage position 36b while the battery 10 is not present. As a result, “sky”, “small” and “medium” become “small”, “medium” and “full”.

  The fourth user accommodates the battery 10 requiring charging in the casing 34 from the first accommodation position 36a and the second accommodation position 36b in the same manner as described above. At this time, the lower rotary table 54a and the upper rotary table 54b rotate clockwise (rightward) by 90 ° index. Therefore, the index rotation from the initial positions of the lower rotary table 54a and the upper rotary table 54b is 0 °.

  After the fully charged battery 10 ("full") that has reached the first storage position 36a and the second storage position 36b is taken out, this state, that is, the first storage position 36a and the second storage position as described above. At 36b, charging is performed without the battery 10 present. By this charging, “empty”, “small” and “medium” become “small”, “medium” and “full”.

  After the fifth user, the above-described index rotation is repeated. As described above, in the present embodiment, the lower rotary table 54a and the upper rotary table 54b do not rotate only in either the clockwise direction or the counterclockwise direction, but index in one direction up to a predetermined index angle. After the rotation, the motor rotates reversely to a predetermined index angle in the remaining one direction. Therefore, the power transmission cable 800 (see FIGS. 6, 7 and 19) is only twisted and untwisted within a predetermined rotation angle. That is, the twist in the same direction is not continued, and therefore, the damage of the power transmission cable 800 is effectively avoided.

  In addition, the power transmission cable 800 is passed from a position higher than the upper end of the battery 10 placed on the charging stand 100 to a rectangular column-shaped hollow portion 802 formed by combining the back plates 102 and is connected to the device side. It is electrically connected to charging connector 112. Therefore, the length of the power transmission cable 800 from the base point of the twist to the device-side charging connector 112 can be increased. In this case, the degree of twist of the power transmission cable 800 can be reduced as compared with the case where the length from the twist base to the device-side charging connector 112 is small. This also effectively prevents the power transmission cable 800 from being damaged.

  In addition, charging can be continued even while the lower rotary table 54a is rotating.

  Further, since the lower rotary table 54a and the upper rotary table 54b perform the index rotation as described above, the user can easily take out the fully charged battery 10.

  If the second user replaces the battery 10 immediately after the first user replaces the battery 10, the receiver will continue to receive the signal emitted by the transmitter. In the case where reception is continued for a predetermined time as described above, the shutter body 700 may be maintained in the open state after the first user inserts the battery 10 requiring charging. This allows the second user to quickly replace the battery 10 that needs to be charged with a fully charged battery 10.

  Moreover, in the present embodiment, a plurality of batteries 10 are stored while being charged in the magazine type lower rotary table 54a and upper rotary table 54b (charging stand 100). Therefore, it is possible to respond to a request for replacement of the battery 10 requiring charging by a plurality of users.

  The present invention is not particularly limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.

  For example, the number of unit magazines may be increased and stacked. Alternatively, a magazine-type charging device may be configured with only one unit magazine.

  Further, the lower rotary table 54a may be rotated by a plurality of gears (gear group). In this case, a gear is provided on each of the rotating shaft of the motor and the lower rotating table 54a, and the lower rotating table 54a The gear provided in the above may be biased to rotate. The same applies to the upper rotary table 54b.

  The opening / closing shutter may also be constituted by a plurality of gears as described above, and the first opening / closing shutter 38a and the second opening / closing shutter 38b may be opened / closed under the action of the gears.

  Further, the removal detection means of the battery 10 holds the shutters 38a and 38b in the open state even after the charged battery 10 is removed from the charging stand 100 when the detection state of the user is maintained. You may make it.
