Description

[Technical field]

[0001] The present invention relates to a charging device including a device storage box for storing a device such as a tablet terminal while charging it. [Background technology]

[0002] Conventionally, a charging device equipped with a device storage box that can store a device such as a tablet terminal and charge the device while it is stored has been disclosed, for example, in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-011837 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, while the charging device described in Patent Document 1 can store and charge multiple devices at the same time, the number of devices that can be stored at the same time is determined by the number of slots provided in the housing in advance. In other words, the number of devices that can be stored in the housing cannot be changed by adding slots after the charging device is installed. By installing another charging device, it is possible to increase the number of devices that can be stored as a result, but depending on the number of devices that can be stored, adding one more charging device may lead to excessive space usage. In addition, increasing the number of independent charging devices installed may increase the load current, which may cause an overcurrent. On the other hand, by combining a storage and charging unit for devices with specified slots, it is possible to store any number of devices in a minimum amount of space, which is thought to eliminate the problem of load current. However, even if the number of devices that can be stored increases, the current value received from the commercial power source during charging must be kept constant.

[0005] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a charging device that is capable of easily changing the number of devices that can be stored and the layout thereof, and that can maintain a constant current value. [Means for solving the problem]

[0006] In order to achieve the above object, the invention described in claim 1 comprises: On the front The device storage unit has a plurality of storage sections for storing chargeable devices and is provided with a charging mechanism section for charging the stored devices; and a power supply unit that is separate from the device storage unit and supplies power received from a commercial power source to the device storage unit, The power supply unit is equipped with a charging control unit that issues instructions to charge the devices stored in the equipment storage unit while maintaining a constant power supply from the commercial power source. Multiple equipment storage units and Power supply unit and , vertically, horizontally, or in any adjacent arrangement Combine and integrate, Integrated multiple The device is characterized in that the connection parts provided on the equipment housing unit and the power supply unit are connected to each other by cables. Claim 2 The invention described in Claim 1 In the configuration, the power supply unit is characterized in that, under instructions from the charging control unit, it supplies power to the multiple connected equipment storage units in a predetermined order, thereby keeping the power it receives from the commercial power source constant. Effect of the Invention

[0007] According to the present invention, the number of devices that can be stored can be easily changed by changing the number of device storage units. Also, since the device storage units and the power supply unit are independent of each other, a free layout is possible and the charging device can be installed in a minimum space. In addition, by supplying power from the power supply unit to each of the multiple equipment storage units in sequence, the increase in load current can be suppressed regardless of the number of equipment storage units, so that the current received from the commercial power source can be kept constant and overcurrent can be prevented.

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing a charging device of the present invention, Fig. 2 is an explanatory view showing a connection part of an equipment housing unit and a power supply unit, Fig. 3 is a perspective view showing another layout of the charging device of the present invention. 1, the charging device 1 includes a device storage unit 2 capable of storing a plurality of devices M and a power supply unit 3. By changing the number of device storage units 2, the number of devices M that can be stored can be easily changed. 2, the equipment storage unit 2 includes a storage unit-side power receiving section 4 as a connection section, and the power supply unit 3 includes a power supply unit-side power supply section 5 connectable to the multiple equipment storage units 2 via cables 6. The power supply unit-side power supply section 5 includes multiple connection sections 5a, 5b, and 5c. The power supply unit-side power supply section 5 also includes a charging control section 7. The storage unit-side power receiving section 4 of each of the multiple equipment storage units 2 is connected to one of the connection sections 5a, 5b, and 5c of the power supply unit 3 via the cables 6. In addition, since the device storage units 2 are independent of each other, they can be stacked vertically or arranged side by side as shown in Figures 1 and 3, and can be installed in a layout that meets the needs of the user. Therefore, the charging device 1 can be installed in a minimum space without using excessive space. In addition, when adding device storage units 2 later, they can be easily installed because they can be used simply by connecting the newly installed device storage unit 2 and the power supply unit 3 with the cable 6. In addition, as shown in FIG. 3, by combining units having desired functions other than equipment storage, such as a drawer unit U1 and a unit U2 with free space, in addition to the equipment storage unit 2, or by providing wheels, a charging device 1 having functions that meet the user's needs can be assembled.

[0010] The device storage unit 2 has a plurality of storage and charging pockets 8 on the front surface as storage sections for devices M. The storage and charging pockets 8 correspond to a specific device M, which is a portable electronic device such as a tablet-type mobile terminal, and function as a storage section into which the device M can be inserted from the side of the device storage unit 2 and stored. A charging mechanism 9 (e.g., a micro USB connector) corresponding to the device M is provided at the back of the storage and charging pocket 8, and when the device M is stored, the device M can be charged via the charging mechanism 9 by drawing power from a commercial power source via the power supply unit 3.

[0011] Next, charging control of the charging device 1 will be described. FIG. 4 is a flow chart showing a charging mode of a device by the charging device of the present invention. Here, the charging equipment 1 is assumed to include three device housing units 2 as shown in FIG. Charging of the device M is performed while the device M is stored in the storage and charging pocket 8 of the device storage unit 2, and charging is performed by rotating each device storage unit 2 as follows. The power supply unit 3 supplies power to all of the connection parts 5a, 5b, 5c of the power supply unit side power supply part 5 in sequence, one by one, in accordance with instructions from the charging control part 7. That is, the power supply unit 3 passes a charging current in sequence to each of the device housing units 2. At this time, the charging control part 7 issues an instruction to the power supply unit 3 to pass a charging current to each of the connection parts 5a, 5b, 5c in a predetermined sequence. As shown in FIG. 4, under the instruction from the charging control unit 7, the power supply unit 3 passes a current to the connection part 5a of the power supply unit side power supply part 5 (connection confirmation step S1). When a current passes to the connection part 5a, the charging control unit 7 determines that the device storage unit 2 is connected to the connection part 5a, and a charging current is supplied from the power supply unit 3 to the device storage unit 2 connected to the connection part 5a, and charging of the device M stored in the storage and charging pocket 8 is started (charging step S2). The power supply from the power supply unit 3 to the connection part 5a is timer-controlled by the charging control unit 7, and when a preset time has elapsed, an instruction is issued from the charging control unit 7 to the power supply unit 3 to stop the power supply to the connection part 5a and pass a current to the next connection part 5b (connection confirmation step S3). After that, a charging current is supplied to the device storage unit 2 connected to the connection part 5b, and charging of the device M is started (charging step S4). After that, the same operation is repeated for the connection part 5c. In this way, the power supply unit 3 supplies power to all of the connection parts 5a, 5b, 5c of the power supply unit side power supply part 5 in sequence, one by one, in accordance with instructions from the charging control part 7, and executes connection confirmation steps S1, S3, S5 and charging steps S2, S4, S6. After the power supply to all of the connection parts 5a, 5b, 5c has been completed, power is supplied again from the connection part through which the charging current was initially passed (connection part 5a in this case). On the other hand, if the device storage unit 2 is not connected to the connection portion 5b, no current flows in the connection confirmation step S3, so the charging control portion 7 does not supply power to the connection portion 5b (charging step S4), but instead issues an instruction to the power supply unit 3 to supply current to the next connection portion 5c (connection confirmation step S5). If a current flows to the connection portion 5c, charging of the device M stored in the storage and charging pocket 8 of the device storage unit 2 connected to the connection portion 5c begins (charging step S6). In other words, the charging control portion 7 determines whether the device storage unit 2 is connected depending on whether a current flows to each of the connection portions 5a, 5b, and 5c, and determines whether to supply power. In this way, by supplying power to the equipment housing units 2 one by one, an increase in the load current can be suppressed, and an overcurrent can be prevented.

[0012] The charging device 1 of the above-mentioned form comprises an equipment storage unit 2 having a plurality of storage and charging pockets 8 for storing chargeable equipment M and equipped with a charging mechanism section 9 for charging the stored equipment M, and a power supply unit 3 separate from the equipment storage unit 2 for supplying power received from a commercial power source to the equipment storage unit 2. The plurality of equipment storage units 2 and the power supply unit 3 are combined and integrated, and the storage unit side power receiving section 4 of the equipment storage unit 2 and any one of the connection sections 5a, 5b, 5b of the power supply unit 3 are connected to each other by a cable 6. According to the charging device 1 configured in this manner, by changing the number of device storage units 2, it is possible to easily change the number of devices M that can be stored. In addition, since the device storage units 2 and the power supply units 3 are independent of each other, a free layout is possible, and the charging device can be installed in a minimum space.

[0013] The power supply unit 3 also includes a charging control unit 7 that issues instructions to charge the equipment M stored in the equipment storage unit 2 while keeping the power received from the commercial power source constant, and supplies power to the multiple equipment storage units 2 in a predetermined order under instructions from the charging control unit 7. Therefore, by supplying power from the power supply unit 3 to each of the multiple equipment storage units 2 in sequence, the increase in load current can be suppressed regardless of the number of equipment storage units 2, so that the current received from the commercial power source can be kept constant and overcurrent can be prevented.

[0014] The present invention has been described above based on the illustrated examples, and the technical scope of the present invention is not limited to these. For example, the number of device storage units to be incorporated in the charging device can be set arbitrarily as long as it is within the range of the number of devices that can be connected to the power supply unit side power supply unit of the power supply unit. On the other hand, the number of connection parts of the power unit side power supply unit may be changed according to the number of device storage units to be incorporated in the charging device. The charging device may also be provided with a plurality of device storage units each having a different standard for the devices that can be stored therein. Furthermore, confirmation of the connection between the equipment storage unit and the power supply unit is not limited to determining whether or not current flows; for example, a limit switch or the like may be provided at the connection part of the power supply part on the power supply unit side, and the connection of the cable may be recognized to determine whether or not power is to be supplied. In addition, the timing of switching the power supply to each connection part in the power supply section on the power supply unit side is not limited to timer control, and may be, for example, when it is determined that the device is fully charged, when charging has been completed up to a certain current value, or when some kind of signal is received from the device. In addition to the charging control unit of the power supply unit, a charging control unit may also be provided in the device storage unit, and the charging control unit of the device storage unit may issue instructions to charge each stored charging pocket in turn.
