Description

  In the present invention, when a battery that needs to be charged is placed on a charging base at a predetermined position, such as when it is used or the amount of stored electricity is not sufficient, the charging base is displaced and stored in the casing. In addition, the present invention relates to a magazine-type charging device that enables a newly exposed charged battery to be taken out from a casing.

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

  The battery includes 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) positioned at each of the upper and lower ends of the outer shell. Having a housing. A plurality of individual battery core packs are built in the housing. Further, the cover is provided with a handle. The user can hold the handle and insert / remove the battery into / from a compartment disposed under the seating surface 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 batteries that are charged and can be used when necessary 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 for individually storing batteries (portable electric energy storage devices), and therefore, the batteries can be collected, charged and distributed.

  A battery or the like used as a drive source for an electric motorcycle or the like is large in order to ensure 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 to have a vertically long standing posture. It is because it becomes easy to accommodate a battery in a charging device by gravity by setting it to a standing posture.

  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. For this reason, when the user accommodates the battery in the charging device in the wrong direction (posture), the battery side charging connector and the device side charging connector do not correspond to each other, so that charging is not performed. In addition, in this case, there is a concern that the male charging device-side charging connector is damaged.

  The present invention has been made to solve the above-described problem, and provides a magazine-type charging device capable of avoiding damage to the device-side charging connector even if the user inserts the battery in an incorrect posture. For the purpose.

In order to achieve the above object, the present invention provides a magazine type charging apparatus in which a battery that needs to be charged is accommodated in an accommodation position, and a charged battery can be transferred to the accommodation position and taken out from the accommodation position. Because
A rotating table,
A driving device for rotating the rotary table;
A charging stand provided on a turntable and on which a battery is placed;
A device-side charging connector provided on the charging base and engaged with the battery-side charging connector of the battery;
With
The charging stand includes a charging tray in which a connector hole through which the device-side charging connector is passed, and
A slide mechanism for displacing the charging tray in the front-rear direction;
A back plate extending along one side of the battery;
A lifting mechanism for displacing the device-side charging connector in the vertical direction;
Have
A judgment projection is provided on the back plate,
The battery is spaced apart from the upper surface of the battery and is provided at the approximate center of the ceiling surface and extends in a straight line.
An entrance forming portion provided at one end of the handle portion and extending in a direction substantially orthogonal to the extending direction of the handle portion, and having an entrance into which the determination projection enters,
Projecting from the upper surface and continuing to the other end of the handle portion, the distance from the upper surface of the upper end is at least larger than the distance from the upper surface of the lower end of the entrance, and a projecting portion that is a blocking portion between the upper surface,
It is characterized by having.

  In this magazine type charging device, it is possible to slide the charging tray under the action of the slide mechanism, thereby allowing the determination protrusion to enter the entrance formed in the battery and then raising the device-side charging connector. is there. In other words, the apparatus-side charging connector keeps the lowered position in a state where the determination projection does not enter the entrance. That is, only when the battery is placed on the charging tray in such a posture that the end surface on the side where the entrance is formed faces the protrusion for determination, the device-side charging connector rises under the action of the lifting mechanism and the battery-side charging is performed. Engage with the connector. The battery is charged by this engagement.

  In short, when the user places the battery on the charging tray in a wrong posture, for example, the closing portion abuts on the determination projection, and the charging tray cannot be further slid to the back plate side. Under this situation, the device-side charging connector does not rise. For this reason, it can avoid that the apparatus side charge connector contacts and damages the bottom face of a battery.

  In addition, when the apparatus-side charging connector rises after the determination projection enters the battery entrance in the normal posture, the battery is pressed from below. For this reason, since the insertion load reaction force acts on the determination projection, 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.

  According to the present invention, the battery is provided with the entrance, and the determination projection is provided on the back plate of the magazine type charging device. When the battery is accommodated in the magazine type charging device, the determination projection is caused to enter the entrance. Then, the device side charging connector is raised and engaged with the battery side charging connector. That is, when the determination protrusion does not enter the entrance because the battery is in an incorrect posture, the device-side charging connector does not rise. For this reason, it can avoid that the apparatus side charge connector contacts and damages the bottom face of a battery.

  Further, when the apparatus-side charging connector is raised and engaged with the battery-side charging connector with the determination protrusion entering the entrance, the battery is pressed from below, so that an insertion load reaction force acts on the determination protrusion. For this reason, since the battery is held firmly, it is possible to prevent the battery from rattling.

  Hereinafter, preferred embodiments of the magazine type charging device according to the present invention will be described and 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 force supply source for an electric motorcycle EB (see FIG. 21). On the upper surface of the battery 10, the arch portion 12 (second handle portion) having an arch shape formed by bending both ends in the longitudinal direction and continuing to the upper surface, and a tab-shaped protrusion whose upper edge portion is curved in an arc shape The portions 14 (protruding portions) are provided so as to face each other. A distance H2 between the upper end of the tab-like protrusion 14 and the bottom surface of the battery 10 is set to be larger than a distance H1 between the lower end of the arch portion 12 and the bottom surface of the battery 10. In addition, the protrusion height of the tab-shaped protrusion part 14 and the protrusion height of the arch part 12 are substantially equivalent.

  A gripping bar 16 (first handle portion) is bridged from the upper end of the arch portion 12 to the upper end of the tab-like protruding portion 14. That is, the gripping bar 16 extends in a direction substantially orthogonal to the extending direction of the arch portion 12. Here, since both the upper ends of the arch portion 12 and the tab-like protruding portion 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 grip the gripping bar 16 by inserting a hand (finger) into the gripping clearance 18.

  An entrance 20 is opened between the arch portion 12 and the upper surface of the battery 10. A determination projection 108 (see FIGS. 6 and 7), which will be described later, enters the entrance 20. The entrance 20 is continuous with the gripping clearance 18. On the other hand, no opening is formed in the tab-like protrusion 14. That is, the gap 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 on the side where the arch portion 12 (advance port 20) is provided. The battery-side charging connector 22 is engaged with a device-side charging connector 112 (see FIG. 7), which will be described later, so that the lower charger 52a or the upper charger 52b (see FIG. 4) and the battery 10 are both connectors. The battery is electrically connected through the terminals 22 and 112 and charged. The battery-side charging connector 22 includes a plurality of plate-like terminal entry recesses 24 and two rod entry recesses 26 that sandwich the plate-like terminal entry recesses 24 (see FIG. 2).

  When the battery 10 configured as described above is viewed in plan, the shape thereof is substantially square or substantially rectangular (see particularly FIG. 8). In this case, the space on the lower rotation table 54a can be used more effectively than when the shape of the battery 10 in 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. The magazine-type charging device 30 has two unit magazines arranged (stacked) in the vertical direction, that is, a first unit magazine 32a and a second unit magazine 32b, and the first unit magazine 32a 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 store four batteries 10, and a first storage position 36a and a second unit for storing the battery 10 in the first unit magazine 32a. A first opening / closing shutter 38a and a second opening / closing shutter 38b are provided as opening / closing shutters in the second storage position 36b for storing in the magazine 32b. As can be understood from FIG. 3, the first storage position 36a and the second storage position 36b are offset from each other in plan view. The first storage position 36a and the second storage position 36b are also take-out positions for taking out the battery 10, and this will be described later.

  In addition, a receiver (communication means) (not shown) is mounted on the casing 34. A receiver receives the signal which the smart phone and RF key which a user possesses, or the electric motorcycle EB (refer FIG. 21) transmits. 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 includes a lower charger 52a for charging the battery 10 mounted on the first unit magazine 32a, and a lower side for rotating the lower side rotation table 54a. The drive motor 56a is provided close to each other. On the other hand, the middle side base plate 50b constituting the second unit magazine 32b is provided with an upper stage driving motor 56b for rotating the upper stage rotating table 54b. 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 32 a and the second unit magazine 32 b are stacked one above the other, and the lower stage rotating table 54 a and the upper stage rotating table 54 b are offset from each other. The lower stage charger 52a, the lower stage driving motor 56a, and the upper stage driving motor 56b are arranged in a space generated by this offset arrangement. For this reason, the occupation area per unit of the magazine type charging device 30 is reduced.

  The lower drive motor 56a is disposed on the side of the lower turn table 54a, and the upper drive motor 56b is disposed on the side of the upper turn table 54b. Therefore, the height positions of the lower stage side rotary table 54a and the upper stage side rotary table 54b are not restricted by the heights of the lower stage side drive motor 56a and the upper stage side drive motor 56b. In other words, the lower stage rotating table 54a and the upper stage rotating table 54b can be disposed at a height at which the battery 10 can be easily inserted and removed.

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

  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, the charging unit 90 on which the battery 10 is placed integrally rotates with the index as the lower rotation table 54a rotates with an index on the lower base plate 50a. The first opening / closing shutter 38a covers a part of the charging unit 90 so as to be exposed at the first accommodation position 36a (see FIG. 3). In other words, the charging unit 90 located at the first housing 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. 6 and 7 are schematic perspective views of the 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 turntable 54 a, and four charging bases 100 provided on the turntable 92. The charging bases 100 are partitioned by a back plate 102, and each charging base 100 is provided with a charging tray 104. A part of the charging stand 100 is passed through an insertion hole 105 formed in the turntable 92, and rotates integrally with the lower stage turntable 54a and the turntable 92 (see FIG. 5).

  A proximity sensor 106 is installed on the back plate 102, and a substantially U-shaped determination projection 108 protrudes above the proximity sensor 106. A part of the back plate 102 protrudes from the lower surface of the turntable 92 and is connected to the lower stage rotary table 54a. That is, the back plate 102 is supported by the lower-stage rotary table 54a in a standing posture. For this reason, the back plate 102 also rotates integrally with the lower-stage side rotary table 54a and the turntable 92.

  The inner end surface of the back plate 102 is disposed at a portion offset from the end surface of another back plate 102. For this reason, when the four back plates 102 are combined, a square columnar 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 represented as a first battery 10a, a second battery 10b, a third battery 10c, and a fourth battery 10d. The third battery 10c faces each other, and the second battery 10b and the fourth battery 10d face each other.

  Further, when the left virtual line L1 in contact with the left corners of the first battery 10a and the third battery 10c facing each other and the right virtual line L2 in contact with the right corners are drawn, the left virtual line L1 is the second virtual line L1. Crosses the battery 10b. Similarly, the right virtual line L2 intersects the fourth battery 10d.

  Further, 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 “upper” represent directions when the user views the charging unit 90 in a plan view, and do not mean the right side, the left side, or the upper side of the battery 10.

  Thus, the batteries 10 facing each other and the adjacent batteries 10 are placed on the charging stand 100 in the casing 34 so that they are offset from each other. For this reason, compared with the case where the four batteries 10 are arrange | positioned in the square vertex position and make it completely oppose, the space on the lower stage side rotation table 54a can be utilized effectively.

  As can be understood from FIG. 8, adjacent batteries 10, that is, the first battery 10 a and the second battery 10 b, the second battery 10 b and the third battery 10 c, the third battery 10 c and the fourth battery 10 d, 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 can slide in the direction of arrow A, that is, front and rear (A1 direction, A2 direction) in a front view. In addition, the arrow A direction in subsequent drawings corresponds to the arrow A direction in FIGS. 6 and 7. Hereinafter, in accordance with the sliding direction of the charging tray 104, the side away from the device-side charging connector 112 (A1 direction side) may be referred to as “front”, and the adjacent side (A2 direction side) may be referred to as “rearward”. In the following description, “front end” represents an end portion on the A1 side, and “rear end” represents an end portion on the A2 side.

  The charging tray 104 is located in the forefront when the battery 10 is not placed at the first accommodation position 36a. FIG. 6 shows a state where the charging tray 104 is slightly biased forward. The charging tray 104 is slid rearward (A2 side) after the battery 10 is placed. When the position of the connector hole 110 corresponds to the position of the device-side charging connector 112 during the backward sliding, 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 accommodation position 36a, the charging tray 104 is located on the rearmost side (A2 side), the device-side charging connector 112 is passed through the connector hole 110, and the battery 10 is mounted. Is placed. For this reason, the charging tray 104 other than the first accommodation position 36a does not slide forward.

  The charging stand 100 includes a support board 200 that faces the charging tray 104 with the through 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 stage rotary table 54a (see FIG. 5).

  As shown in detail in FIG. 9, the device-side charging connector 112 is disposed on the support board 200 so as to be movable 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 therebetween. 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 locking mechanism 400 that positions and fixes the charging tray 104 that slides backward, and an elevating mechanism that raises and lowers the apparatus-side charging connector 112. 500 is provided.

  The slide mechanism 300 includes a plurality of retractable rollers 302 on which the charging tray 104 slides, a moving plate 304 coupled to the lower surface of the charging tray 104, and two pieces provided on the lower surface of the charging tray 104. And a retaining 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 includes 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 retaining plate 305. That is, the front end of the tray discharging spring 310 that is separated from the device-side charging connector 112 is hooked to the spring fixing portion 308 that is positioned and fixed. On the other hand, the rear end close to the apparatus-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, two columnar leg portions 312 are provided below the moving plate 304 so as to hang down. A substantially elliptical elliptic plate 314 is bridged between the legs 312.

  As shown in FIGS. 9 and 10, the lock mechanism 400 is attached to the rack slide 404 and a rack slide 404 that can be displaced along a set of rack guide rails 402 provided on the support board 200. 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 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. (Back or 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 apparatus-side charging connector 112, that is, 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 orthogonal to the arrow A direction. 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 this insertion hole. The claw member 406 is connected to the displacement plate 405 via the first rotation shaft 414 and can rotate about the first rotation shaft 414. Furthermore, one end of the first return spring 416 is hooked on another corner portion of the claw member 406 that faces the one corner portion.

  One of the rack guide rails 402 is provided with a flat plate-shaped spring latching portion 418 so as to protrude in a direction perpendicular to the longitudinal direction thereof. The other end of the first return spring 416 is hooked to the spring hooking portion 418. In other words, the first return spring 416 pulls the claw member 406 toward the spring hooking portion 418 (the front A1 side).

  A set of cam guides extending in a direction substantially perpendicular to the longitudinal direction (direction of arrow A) of the rack guide rail 402 at the rear end of the rack guide rail 402 close to the device-side charging connector 112. The rail 420 is supported. The upper end of the cam member 408 is slidably held by the cam guide rail 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 so as to approach or separate from the device-side charging connector 112. Displace in the direction. This point will be described later.

  The cam member 408 has a second cam portion 424 that cooperates with the first cam portion 412 of the claw 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 a cam member 408 is connected to the rear end of the link member 430 via a connecting shaft 436. Further, the front end of the link member 430 is rotatably connected to the backup plate 434 via a second rotation shaft 440 (see particularly FIG. 12). For this reason, when the cam member 408 is displaced along the cam guide rail 420, the link member 430 changes its posture as shown in FIGS.

  The link member 430 has a first raised portion 442 that protrudes toward the hook member 432 at an intermediate portion between the connecting 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 that protrudes toward the first raised portion 442 of the link member 430. The first raised portion 442 and the second raised portion 446 can get over each other when the link member 430 and the hook member 432 are rotated (see FIGS. 10 to 12).

  At the front end of the hook member 432, a hook portion 450 having a shape in which a portion facing the link member 430 is cut out in a U shape is formed. The leg portion 312 of the moving plate 304 is restrained by the hook portion 450 when the link member 430 and the hook member 432 are in a predetermined positional relationship. As will be described later, due to this restriction, the charging tray 104 is positioned and fixed at the rearmost position. On the other hand, when the rack slide 404 is displaced (retracted) toward the device-side charging connector 112 and the claw member 406 presses the cam member 408, the hook member 432 rotates as shown in FIGS. . By this rotation, the leg portion 312 of the moving plate 304 is released from the hook portion 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 connecting shaft 436 and the first raised portion 442. Is done. The second return spring 452 pulls and urges the rear end of the hook member 432 toward the link member 430.

  As shown in FIG. 13, an elevating mechanism 500 for elevating the apparatus side charging connector 112 includes an elevating motor 502, a worm 504, a worm gear 506, a rack side gear 508 having spur teeth, a rack slide 404, and an apparatus side. And a link portion 510 connecting the charging connector 112. The worm 504 is provided on the rotating shaft of the lifting 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 is provided with 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 an elongated hole 516 through which the first shaft 514 passes. A pair of arm members 518 extending to the lower side of the device-side charging connector 112. The arm member 518 extends to incline from the A2 side to the A1 side, and then bends and extends to incline from the A1 side to the A2 side. The second shaft 520 is passed through the 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 in the vicinity of the guided portion 120. That is, the bearing portion 522 is formed with a long 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 is passed through the elongated hole 524.

  When the lifting motor 502 is energized, the worm 504, the worm gear 506, the transmission shaft 512, and the rack side gear 508 rotate. For this reason, 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. FIG. 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 elevating mechanism 500 further includes a guide rod 526 inserted through 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.

  The tray discharge spring 310 extends and pulls and biases the charging tray 104 toward the A1 direction when the charging tray 104 is not restrained by the snatch lock 410.

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

  As shown in FIG. 17, the lower base plate 50a is provided with a phase holding cylinder 600 (positioning mechanism) for holding the position of the lower stage rotating table 54a. This phase holding cylinder 600 has an advancing / retracting rod 602, and the advancing / retreating rod 602 enters an engaging recess 604 formed on the side peripheral wall of the lower stage rotary table 54a when it moves forward. As a result, the rotation of the lower-stage side rotary table 54a is prevented and held in its phase.

  The lower base plate 50a is further provided with a first cam follower 606 that receives a heavy load, a second cam follower 608 that receives a light load, a third cam follower 610 for centering the lower rotation table 54a, and an interlock switch 612. . The lower rotation 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-stage side rotary table 54 a is configured such that a ring body 614 having a slightly larger thickness than the disk-shaped body 613 is fitted on the side peripheral wall of the disk-shaped body 613. The first cam follower 606 and the second cam follower 608 are in sliding contact with the lower surface of the disk-shaped body 613. On the other hand, the third cam follower 610 slides in a sliding groove 615 formed on 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 engaging recess 604 and the latch groove 620 are arranged every 90 °.

  As shown in FIG. 18, the lower base plate 50 a may be provided with a bearing 622 instead of the third cam follower 610. In this case, a bearing receiver 624 is provided on the lower stage rotary table 54 a (disk-shaped body 613), and the lower stage rotary table 54 a can be centered by the bearing 622 and the bearing receiver 624. For this reason, there is an advantage that the number of parts is reduced. Therefore, it is not particularly necessary to provide the third cam follower 610.

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

  As shown in FIG. 19, the first opening / closing shutter 38 a has a shutter body 700. The shutter main body 700 rotates under the action of a shutter opening / closing motor 702. Among them, the shutter main body 700 has a fan shape, a first portion 704 that covers the upper surface side of the battery 10 (the arch portion 12, the tab-like protruding portion 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 that is interposed between the first portion 704 and the second portion 706 so as to be curved. Further, an annular driving force transmission unit 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 transmission unit 710.

  As shown in FIG. 20, the shutter body 700 includes a fourth portion 716 and a fifth portion 718 having different radii 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 portion 720 interposed between the fourth portion 716 and the fifth portion 718.

  The shutter bearing 714 is provided at a position higher than the upper end (the arch portion 12, the tab-like protruding portion 14, and the gripping bar 16) of the battery 10 placed on the charging stand 100. Thereby, it is avoided that the battery 10 interferes with the shutter bearing 714.

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

  A large pulley 722 (or a large sprocket) as a transmission mechanism is provided outside the shutter bearing 714. An opening / closing belt 726 (or an opening / closing chain) is wound around the large pulley 722 and a small pulley 724 (or a small sprocket) provided on the rotating shaft of the shutter opening / closing motor 702. The large pulley 722 is preferably 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-stage 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, it passes through a quadrangular prism-shaped hollow portion 802 (see FIGS. 6 and 7) configured by combining the back plates 102. In addition, the power transmission cables 800 are converged by a focusing band 804, which prevents the twist 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 is omitted. In the second unit magazine 32b, the 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 for fixing the battery 10. In the following, a case where two batteries 10 are replaced at the same time is illustrated, but it is needless to say that the number of replacements may be only one.

  The battery 10 is used, for example, as a drive source for 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 type charging device 30 described above.

  The magazine type charging device 30 is installed at a predetermined charging station ST provided outdoors. The user may approach the magazine-type charging device 30 in a state of getting on the electric motorcycle EB or on foot. At this time, both the first opening / closing shutter 38a and the second opening / closing shutter 38b are closed.

  As described above, the electric motorcycle EB, or the smartphone or RF key possessed by the user is provided with a transmitter. The receiver provided in the casing 34 of the magazine type charging device 30 receives a signal transmitted from the transmitter. Recognizing that the receiver has received the signal for a predetermined time set in advance, the control device 60 issues a command signal “open shutter” to the shutter opening / closing motor 702 (see FIG. 19). The control device 60 maintains the open state of the shutters 38a and 38b 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 a signal from the transmitter, the reception period is short. In this case, control is performed so that the shutter main body 700 does not rotate.

  The shutter opening / closing motor 702 is energized based on the command signal “open shutter”, and the small pulley 724 rotates and the opening / closing belt 726 rotates. As a result, the large pulley 722 which is a transmission mechanism rotates, and the shutter main body 700 rotates around the driving force transmission portion 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 in the 1st accommodation position 36a and the 2nd accommodation position 36b and by extension, the charging stand 100 are exposed to the exterior of the casing 34. FIG.

  As described above, according to the present embodiment, the shutter main body 700 automatically rotates, so that the user does not need to rotate the shutter main body 700. Therefore, the charged battery 10 can be taken out only by approaching the magazine-type charging device 30, and the battery 10 that has been used or has an insufficient amount of charge 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. Have For this reason, the length in the depth direction required when the shutter main body 700 changes from the closed state to the open state is shortened. Therefore, the installation area per one magazine-type charging device 30 can be reduced.

  While the shutter body 700 is open, for example, an object such as a user's hand may come into contact with the shutter body 700. At this time, torque acts on the shutter body 700. When the torque limiter 728 is provided on the large pulley 722, the control device 60 detects that 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 main body 700 and the shutter bearing 714, and an object is prevented from being pinched by the shutter main 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 the state in which the charging bases 100 of the first unit magazine 32a and the second unit magazine 32b slide forward. The battery 10 that needs to be charged is placed on the charging tray 104 so that the entrance 20 faces the back plate 102 (determination protrusion 108). That is, the battery 10 that requires charging is inserted into the casing 34 from the first accommodation position 36a and the second accommodation 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 charging base 100 of the first unit magazine 32a and the second unit magazine 32b, and each charging base 100 The battery 10 that needs to be charged is remarkably facilitated.

  When the battery 10 that requires charging is placed on the charging tray 104, a situation where the user accidentally removes his / her hand from the gripping bar 16 is assumed. 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 body of the retractable roller 302, and the like can be avoided.

  When the battery 10 that needs to be charged is placed on the charging tray 104, the device-side charging connector 112 is lowered and positioned below the lower-stage rotary table 54a (see FIG. 6). Therefore, for example, even when the user mistakenly places the battery 10 on the charging tray 104 with the tab-shaped protrusion 14 facing the back plate 102 (determination protrusion 108), the battery-side charging connector 22 is It is effectively prevented that the non-existing bottom face comes into contact with the device-side charging connector 112. Therefore, it is avoided that the device side charging connector 112 is damaged due to the contact.

  After placing the battery 10 on the charging tray 104, the user presses the charging tray 104 toward the back plate 102 side. In other words, the charging tray 104 is slid together with the battery 10 to the back plate 102 side (rear A2 direction side). With this slide, the latch plate 305 is displaced rearward integrally with the charging tray 104, so that the tray discharging spring 310 that has been contracted so far 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 a state before the charging tray 104 is slid rearward, as shown in FIG. 12, the snatch lock 410 has the hook portion 450 of the hook member 432 spaced apart from the front end of the link member 430. At this time, the second raised portion 446 is in front 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 portion 312 presses the inner wall on the rear end side of the hook portion 450. By this pressing, the hook member 432 rotates about 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 expands.

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

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

  In the state where 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 portion 450 is closed (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 raised portion 446 pushing the first raised portion 442 forces the hook member 432 and the link member 430 to be forced. The charging tray 104 does not slide. For this reason, the leg portion 312 is restrained by the hook portion 450, and the charging tray 104 is locked at a position close to the device-side charging connector 112.

  The determination projection 108 enters the entrance 20 of the battery 10 slid to the back plate 102 side. In response to this approach, the proximity sensor 106 provided on the back plate 102 detects the presence of the battery 10. Receiving this detection signal, control device 60 recognizes that “battery 10 has moved to the normal charging position”.

  On the other hand, when the tab-like protruding portion 14 faces the back plate 102 because the battery 10 is mistakenly inserted, the tab-like protruding portion 14 comes into contact with the determination protrusion 108. Since H2> H1 as shown in FIG. 1A, the upper end of the tab-like protrusion 14 is higher than the lower end of the arch part 12 (the bottom of the entrance 20), and the tab-like protrusion 14 is a blocking part. Because. Accordingly, the battery 10 is stopped, and the charging tray 104 cannot be slid further back. 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 proper 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 reinserted in a normal posture.

  When the controller 60 recognizes that “the battery 10 has moved to the regular charging position”, the controller 60 energizes the lifting 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 are driven to rotate, and as a result, the rack slide 404 is displaced in a direction away from the apparatus side charging connector 112. That is, the rack slide 404 moves forward in the A1 direction.

  As the rack slide 404 moves forward, the first shaft 514 provided at the rear end of the rack slide 404 also moves forward 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, even when the rack slide 404 moves forward, it will be described that the cam member 408 holds the position displaced toward the claw member 406 and the later-described charging tray 104 is not unlocked. 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 moving forward interferes with the tip of the second cam portion 424 of the cam member 408.

  When the rack slide 404 further advances, the first cam portion 412 is pressed from the second cam portion 424 because the tip of the first cam portion 412 interferes with the tip of the second cam portion 424 of the cam member 408. The claw member 406 that has received this pressure rotates about the first rotation shaft 414 so that the first cam portion 412 moves rearward. At the same time, the first return spring 416 extends.

  By the above rotation, interference of the first cam portion 412 with respect to the second cam portion 424 is avoided. When the first cam portion 412 is positioned in front of the second cam portion 424 as the rack slide 404 moves forward, the first return spring 416 contracts, and the claw member 406 is tensioned forward. As a result, the claw member 406 returns to the original posture by rotating in the opposite direction. Further, the rotation of the claw member 406 in the opposite direction is limited.

  The guided portion 120 of the device-side charging connector 112 is guided by the guide rod 526 that is 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 in which the rack slide 404, the displacement plate 405, and the claw member 406 are advanced to the maximum.

  The device-side charging connector 112 raised 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-like terminal 114 enters the plate-like 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 with respect to the entrance 20. In particular, the determination protrusion 108 applies an insertion load reaction force to the bottom of the entrance 20. For this reason, the battery 10 is prevented from being displaced or rattling or toppling over.

  Thus, according to the present embodiment, when the battery 10 that needs to be charged 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. Whether or not the battery 10 is inserted in a normal posture can be determined only by performing a simple operation of sliding the charging tray 104 on which the battery 10 is placed to the back plate 102 side. At the same time, the device-side charging connector 112 or the battery-side charging connector 22 can be prevented from being damaged, and the battery 10 can be held firmly.

  Alternatively, a warning sound may be emitted when the device-side charging connector 112 does not rise even after a predetermined time has elapsed after the user has inserted the battery 10 that needs charging. Thereby, the user can recognize whether the battery 10 that needs to be charged is inserted in an incorrect posture or whether the device-side charging connector 112 is not raised for some reason.

  Thereafter, the control device 60 issues a command signal to the shutter opening / closing motor 702 to rotate the small pulley 724 and rotate 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 / her hand into the casing 34.

  Thus, 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, the battery 10 and the charging stand 100 are prevented from coming into contact with rainwater or dust even outdoors. That is, the magazine type charging device 30 can be suitably used even outdoors.

  Next, the controller 60 energizes the lower drive motor 56a and the upper drive motor 56b. As a result, the lower stage rotating table 54a and the upper stage rotating table 54b rotate as the timing belt 616 rotates. 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 indicate the battery 10 that is difficult to discharge any more and needs to be charged, and the discharge capacity is recovered when charging is started. The battery 10 being charged, the battery 10 being charged whose discharge capacity has been largely recovered after a certain amount of time has elapsed since the start of charging, and the fully charged battery 10 being fully charged after the discharge capacity has been recovered are shown. That is, “empty” does not mean that the battery 10 does not exist.

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

  The phase determination of the lower rotation table 54a after the index rotation is made when the interlock switch 612 (see FIGS. 17 and 18) detects the position of the latch groove 620. Then, after it is determined that the lower stage rotating table 54a is rotated by 90 ° index, the advance / retreat rod 602 of the phase holding cylinder 600 moves forward and enters the engagement recess 604. Due to this approach (engagement), the rotation of the lower-stage rotary table 54a is prevented.

  In addition, during the index rotation of the lower stage rotating table 54a, the second cam follower 608 prevents the lower stage rotating 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 also operates in the same manner as described above.

  The control device 60, which has recognized that the lower rotation table 54a has been rotated by 90 ° index, is charged by a command signal at the first storage position 36a and the second storage position 36b to which the fully charged battery 10 has been transferred. Only the raising / lowering motor 502 (refer FIG.9 and FIG.13) provided in the support board 200 of 100 is energized. That is, the remaining three lifting motors 502 are not energized simultaneously with the above energization.

  As the elevating motor 502 is energized, the worm 504 rotates in the reverse direction. As the worm gear 506, the transmission shaft 512, and the rack-side gear 508 are rotated following this rotation, the rack slide 404 is displaced so as to approach the device-side charging connector 112. That is, it moves backward in the A2 direction.

  As the rack slide 404 moves backward, the first shaft 514 integrally moves backward in the A2 direction. Accordingly, the upper end of the arm member 518 is pulled backward (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 positioned below the lower-stage rotary table 54a through the connector hole 110 of the charging tray 104. During the lowering, 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 moves 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 received this pressure is displaced along the cam guide rail 420 in a direction away from the rack guide rail 402.

  Accordingly, 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 positioned in front of the first raised portion 442 (A1 direction side). Accordingly, the link member 430 draws the hook member 432 through the second return spring 452.

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

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

  Therefore, the charging tray 104 slides in the direction opposite to the apparatus-side charging connector 112, that is, the A1 direction side, which is the front, integrally with the retaining 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 plate 200.

  In this way, the charging tray 104 is returned to the forward movement position at the first storage position 36a. At this time, the charged battery 10 also moves forward and separates from the back plate 102. Accordingly, the entrance 20 of the battery 10 is detached from the determination projection 108 of the back plate 102.

  In the present embodiment, after the proximity sensor 106 detects that the charged battery 10 is 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 and the open / close belt 726 rotates, and the large pulley 722 rotates to open the first open / close shutter 38a and the second open / close shutter 38b. Thereafter, the user may take out the fully charged battery 10 transferred to the first accommodation position 36a and the second accommodation position 36b from the casing 34 and attach it to the electric motorcycle EB.

  As shown in FIG. 8, the extending directions of the gripping bars 16 are substantially orthogonal to each other between adjacent batteries 10. Therefore, the extending direction of the gripping bar 16 when the user takes out the fully charged battery 10 coincides with the extending direction of the gripping bar 16 when the battery 10 requiring charging is accommodated. For this reason, the battery 10 can be easily taken out.

  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 are transferred to the first accommodation position 36a and the second accommodation position 36b. For this reason, it is possible to prevent the user from putting his / her hand into the casing 34 while the charging unit 90 is index rotating.

  After the charged battery 10 is taken out, 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. For this reason, it is avoided that the user touches the shutter main body 700 while the battery 10 is being taken out. Further, it is possible to prevent the user from putting his / her hand into the casing 34 after taking out.

  By removing the charged battery 10 as described above, the battery 10 is absent at the first accommodation position 36a and the second accommodation position 36b. Under this circumstance, 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. Accordingly, the charging of the three (total six) batteries 10 remaining in the first unit magazine 32a and the second unit magazine 32b proceeds, and the battery 10 that needs to be “empty” until then becomes “small”. " Similarly, the battery 10 that was “small” is “medium”, and the battery 10 that was “medium” is “full”. The battery 10 remains absent at the first storage position 36a and the second storage position 36b.

  The second user accommodates the battery 10 that needs to be charged into 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-stage rotary table 54a and the upper-stage rotary table 54b are rotated by 90 ° in the clockwise direction (rightward). Therefore, the lower stage rotary table 54a and the upper stage rotary table 54b are 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. In 36b, the battery 10 is charged without being present. As a result, “empty”, “small”, and “medium” become “small”, “medium”, and “full”.

  The third user accommodates the battery 10 that needs to be charged into 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 stage rotating table 54a and the upper stage rotating table 54b rotate by 270 ° in the counterclockwise direction (left direction). Therefore, the index rotation from the initial position of the lower-stage side rotary table 54a and the upper-stage side rotary table 54b is −90 °.

  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. In 36b, the battery 10 is not present, and the battery 10 is charged by the charging unit 90 at a position other than the first accommodation position 36a and the second accommodation position 36b. As a result, “empty”, “small”, and “medium” become “small”, “medium”, and “full”.

  The fourth user houses the battery 10 that needs to be charged in the casing 34 from the first housing position 36a and the second housing position 36b in the same manner as described above. At this time, the lower rotation table 54a and the upper rotation table 54b rotate by 90 ° in the clockwise direction (rightward). Therefore, the index rotation from the initial position of the lower-stage side rotary table 54a and the upper-stage side 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. In 36b, the battery 10 is charged without being present. By this charging, “empty”, “small”, and “medium” become “small”, “medium”, and “full”.

  After the fifth user, the above index rotation is repeated. As described above, in the present embodiment, the lower stage rotating table 54a and the upper stage rotating table 54b do not rotate only in either the clockwise direction or the counterclockwise direction, but are indexed in one direction up to a predetermined index angle. After the rotation, it rotates backward 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, twisting in the same direction is not continued, and therefore, it is effectively avoided that the power transmission cable 800 is damaged.

  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 through a quadrangular prism-shaped hollow portion 802 formed by combining the back plates 102 to the device side. It is electrically connected to the charging connector 112. For this reason, the length from the twist base point to the device-side charging connector 112 of the power transmission cable 800 can be increased. In this case, the degree of twisting of the power transmission cable 800 can be reduced as compared with the case where the length from the twisting base point to the device-side charging connector 112 is small. This also effectively prevents the power transmission cable 800 from being damaged.

  In addition, it is possible to continue charging while the lower stage rotary table 54a is rotating.

  Further, since the lower stage rotating table 54a and the upper stage rotating table 54b perform 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 continues to receive the signal emitted by the transmitter. As described above, when reception is continuously performed for a predetermined time, the shutter main body 700 may be maintained in the open state after the first user inserts the battery 10 that needs to be charged. As a result, the battery 10 that needs to be quickly charged by the second user can be replaced with a fully charged battery 10.

  Moreover, in the present embodiment, the plurality of batteries 10 are stored while being charged in the magazine-type lower rotating table 54a and the upper rotating table 54b (charging base 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 modifications can be made without departing from the gist of the present invention.

  For example, the number of unit magazines may be increased and stacked. Or you may make it comprise a magazine type charging device only with one unit magazine.

  Further, the lower stage rotary table 54a may be rotated by a plurality of gears (gear groups). In this case, a gear is provided for each of the rotation shaft of the motor and the lower rotation table 54a, and the lower rotation table 54a is directly attached with a gear attached to the rotation shaft of the motor or indirectly with one or more other gears. What is necessary is just to energize the gear provided in the rotation. The same applies to the upper stage rotary table 54b.

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

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