Description

本発明は、たとえばタブレット端末等の機器を充電しながら保管するための機器収納用箱体を備えた充電装置に関する。 The present invention relates to a charging device equipped with a device storage box for storing devices such as tablet terminals while charging them.

従来、タブレット端末等の機器を収納して保管するとともに、保管状態において機器を充電することができる機器収納用箱体を備えた充電装置としては、たとえば特許文献１に記載されているようなものがある。 Conventionally, a charging device equipped with a device storage box that can store devices such as tablet terminals and charge the devices while they are stored is, for example, as described in Patent Document 1.

特開２０１７－０１１８３７号公報JP 2017-011837 A

しかし、特許文献１に記載の充電装置は、複数の機器を同時に収納して充電可能である一方、同時に収納できる機器の台数が、予め筐体に設けられたスロットの数によって決まっている。つまり、充電装置の設置後にスロットを増やす等して筐体の収納可能台数を変更することができない。もう１台の充電装置を設置することで、結果として収納可能な機器の台数を増加させることは可能だが、増加させたい収納可能台数によっては、充電装置を１台増やすことで過剰なスペースの使用につながる可能性がある。また、それぞれが独立する充電装置の設置台数を増やすことで、負荷電流が増加し、過電流となる可能性もある。
一方、所定のスロットを備える機器の収納充電ユニットを組み合わせることで、最低限のスペースで任意の台数を収納可能となり、負荷電流の問題も解消可能になると考えられるが、収納可能台数が増加しても、充電時に商用電源から受け取る電流値を一定に保つ必要がある。 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.

そこで、本発明の目的は、機器の収納可能台数及びレイアウトを容易に変更可能で、電流値を一定に保持可能な充電装置を提供することにある。 The object of the present invention is to provide a charging device that can easily change the number of devices that can be stored and the layout, and can maintain a constant current value.

上記目的を達成するために、請求項１に記載の発明は、前面に充電可能な機器を保管する複数の保管部を有し、保管されている機器を充電するための充電機構部を備える機器収納用ユニットと、機器収納用ユニットとは別体で、商用電源から受け取る電力を機器収納用ユニットに供給する電源ユニットとを備え、電源ユニットは、商用電源から受け取る電力を一定に保ちながら機器収納用ユニットに保管された機器を充電するための指示を出す充電制御部を備え、それぞれ前向きにした複数の機器収納用ユニット及び電源ユニットとを、上下、又は左右に隣接する任意の配置で組み合わせて一体化し、一体化された複数の機器収納用ユニット及び電源ユニットそれぞれに設けられた各々の接続部同士を互いにケーブルで接続して為ることを特徴とする。
請求項２に記載の発明は、請求項１の構成において、電源ユニットは、充電制御部からの指示の下、接続された複数の機器収納用ユニットに対して予め定められた順番に従って、電力を供給することで商用電源から受け取る電力を一定に保つことを特徴とする。 In order to achieve the above-mentioned object, the invention described in claim 1 comprises an equipment storage unit having a plurality of storage sections on the front side for storing chargeable devices and equipped with a charging mechanism section for charging the stored devices, and a power supply unit separate from the equipment storage unit for supplying power received from a commercial power source to the equipment storage unit , the power supply unit having a charging control section that issues instructions to charge the devices stored in the equipment storage unit while keeping the power received from the commercial power source constant, and a plurality of equipment storage units and power supply units , each facing forward, are combined and integrated in any adjacent arrangement vertically or horizontally , and the respective connection sections provided on the integrated plurality of equipment storage units and power supply units are connected to each other by cables.
The invention described in claim 2 is characterized in that, in the configuration of claim 1 , the power supply unit keeps the power received from the commercial power source constant by supplying power to the multiple connected equipment storage units in a predetermined order under instructions from the charging control unit.

本発明によれば、機器収納用ユニットの台数を変更することで、機器の収納可能台数を容易に変更可能である。また、機器収納用ユニットと電源ユニットとがそれぞれ独立しているため、自由なレイアウトが可能であり、最低限のスペースで充電装置を設置できる。
また、複数の機器収納用ユニットそれぞれに、１台ずつ順番に電源ユニットから電力を供給することで、機器収納用ユニットの数に依らず、負荷電流の増加を抑えられるため、商用電源から受け取る電流を一定に保ち、過電流となることを防止できる。 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.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、本発明の充電装置を示す斜視図である。図２は、機器収納用ユニット及び電源ユニットの接続部を示す説明図である。図３は、本発明の充電装置の別のレイアウトを示す斜視図である。
充電装置１は、図１に示すように、複数の機器Ｍを収納可能な機器収納用ユニット２と電源ユニット３とを備える。機器収納用ユニット２の台数を変更することで、機器Ｍの収納可能台数を容易に変更できる。
機器収納用ユニット２は、図２に示すように、接続部としての収納用ユニット側電力受取部４を備え、電源ユニット３は、複数の機器収納用ユニット２とケーブル６を介して接続可能な電源ユニット側電力供給部５を備える。電源ユニット側電力供給部５は、複数の接続部５ａ，５ｂ，５ｃを備える。また、電源ユニット側電力供給部５は、充電制御部７を備える。複数の機器収納用ユニット２それぞれの収納用ユニット側電力受取部４は、ケーブル６を介して電源ユニット３の各接続部５ａ，５ｂ，５ｃのいずれかに接続される。
また、機器収納用ユニット２は、それぞれが独立しているため、図１及び図３に示すように、上下に積むことも、左右に並べることも可能であり、ユーザのニーズに合わせたレイアウトで設置できる。従って、過剰なスペースを使用することなく、最低限のスペースで充電装置１を設置可能となる。加えて、後から機器収納用ユニット２を増設する際にも、新たに設置する機器収納用ユニット２と電源ユニット３とをケーブル６で繋ぐだけで使用可能とできるため、容易に設置可能である。
また、図３に示すように、機器収納用ユニット２以外に、引き出しユニットＵ１、フリースペースを備えるユニットＵ２等、機器収納以外の所望の機能を備えるユニットを組み合わせたり、車輪を設けたりすることで、ユーザのニーズに沿った機能を有する充電装置１を組むことができる。 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 between an equipment storage unit and a power supply unit, and 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.
Furthermore, as shown in FIG. 3, in addition to the equipment storage unit 2, a charging device 1 having functions that meet the user's needs can be assembled by combining units having desired functions other than equipment storage, such as a drawer unit U1 and a unit U2 with free space, or by providing wheels.

機器収納用ユニット２は、前面に機器Ｍの保管部としての収納充電ポケット８を複数備える。収納充電ポケット８は、タブレット型携帯端末等の携帯型電子機器である所定の機器Ｍと対応しており、機器収納用ユニット２の側方から機器Ｍを挿入して収納可能な収納部として機能する。また、収納充電ポケット８の奥部には、機器Ｍに対応する充電機構部９（例えばマイクロＵＳＢコネクタ）が設けられており、機器Ｍの収納時に、電源ユニット３を介して商用電源から電源をとることで、充電機構部９を介して機器Ｍを充電可能となっている。 The device storage unit 2 has a number of storage and charging pockets 8 on the front as storage areas 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 area into which the device M can be inserted from the side of the device storage unit 2 and stored. In addition, 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, it is possible to charge the device M via the charging mechanism 9 by drawing power from a commercial power source via the power supply unit 3.

続いて、充電装置１の充電制御について説明する。
図４は、本発明の充電装置による機器の充電様式を示すフローチャートである。
ここで、充電装置１は、図１に示すように、３台の機器収納用ユニット２を備えるものとする。
機器Ｍの充電は、機器Ｍを機器収納用ユニット２の収納充電ポケット８に収納した状態で行われ、以下のように、機器収納用ユニット２毎への輪番充電により実施される。
電源ユニット３は、充電制御部７の指示に従い、電源ユニット側電力供給部５の全ての接続部５ａ，５ｂ，５ｃに、１箇所ずつ順番に電力を供給する。即ち、電源ユニット３は、各機器収納用ユニット２に１つずつ順番に充電電流を流す。この時、充電制御部７は、各接続部５ａ，５ｂ，５ｃに予め定められた順番に従って充電電流を流すように電源ユニット３に対して指示を出す。
図４に示すように、充電制御部７からの指示の下、電源ユニット３は、電源ユニット側電力供給部５の接続部５ａに電流を流す（接続確認ステップＳ１）。接続部５ａに電流が流れた場合、充電制御部７は、接続部５ａに機器収納用ユニット２が接続されていると判断し、電源ユニット３から接続部５ａに接続された機器収納用ユニット２へ充電電流が供給され、収納充電ポケット８に収納された機器Ｍの充電が開始される（充電ステップＳ２）。 電源ユニット３から接続部５ａへの電力供給は、充電制御部７によりタイマー制御され、予め設定された時間が経過すると、接続部５ａへの電力供給を止めて次の接続部５ｂに電流を流す指示が充電制御部７から電源ユニット３に出される（接続確認ステップＳ３）。その後、接続部５ｂに接続された機器収納用ユニット２に充電電流が供給され、機器Ｍの充電が開始される（充電ステップＳ４）。その後、接続部５ｃに対しても同様の動作が繰り返される。
このように、電源ユニット３は、充電制御部７からの指示に従い、電源ユニット側電力供給部５の全ての接続部５ａ，５ｂ，５ｃに１箇所ずつ順番に電力供給を行い、接続確認ステップＳ１，Ｓ３，Ｓ５と充電ステップＳ２，Ｓ４，Ｓ６とを実行する。全ての接続部５ａ，５ｂ，５ｃに対して、一通り電力供給が終わった後は、最初に充電電流を流した接続部（ここでは接続部５ａ）から、再度、電力供給を行う。
一方、仮に接続部５ｂには機器収納用ユニット２が接続されていなかったとすると、接続確認ステップＳ３において、電流が流れないため、充電制御部７は、接続部５ｂへの電力供給（充電ステップＳ４）は行わず、さらに次の接続部５ｃに電流を流す指示を電源ユニット３に出す（接続確認ステップＳ５）。接続部５ｃに電流が流れた場合、接続部５ｃに接続された機器収納用ユニット２の収納充電ポケット８に収納された機器Ｍの充電が開始される（充電ステップＳ６）。つまり、充電制御部７は、各接続部５ａ，５ｂ，５ｃに電流が流れるか否かで、機器収納用ユニット２の接続を判断し、電力供給を行うか否かを決定する。
このように、機器収納用ユニット２に対する電力供給を１ユニットずつ行うことで、負荷電流の増加を抑制し、過電流となることを防止できる。 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 device 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/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 equipment 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 flows 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 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). Then, 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). Then, 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 unit 7 does not supply power to the connection portion 5b (charging step S4), but 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 is started (charging step S6). In other words, the charging control unit 7 judges the connection of the device storage unit 2 based on whether a current flows to each of the connections 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.

上記形態の充電装置１は、充電可能な機器Ｍを保管する複数の収納充電ポケット８を有し、保管されている機器Ｍを充電するための充電機構部９を備える機器収納用ユニット２と、機器収納用ユニット２とは別体で、商用電源から受け取る電力を機器収納用ユニット２に供給する電源ユニット３とを備え、複数の機器収納用ユニット２と電源ユニット３とを組み合わせて一体化し、機器収納用ユニット２の収納用ユニット側電力受取部４及び電源ユニット３の接続部５ａ，５ｂ，５ｂの何れかを互いにケーブル６で接続して為る。
このようにして構成される充電装置１によれば、機器収納用ユニット２の台数を変更することで、機器Ｍの収納可能台数を容易に変更可能である。また、機器収納用ユニット２と電源ユニット３とがそれぞれ独立しているため、自由なレイアウトが可能であり、最低限のスペースで充電装置を設置できる。 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 unit 3 are independent of each other, a free layout is possible, and the charging device can be installed in a minimum space.

また、電源ユニット３は、商用電源から受け取る電力を一定に保ちながら機器収納用ユニット２に保管された機器Ｍを充電するための指示を出す充電制御部７を備え、充電制御部７からの指示の下、複数の機器収納用ユニット２に対して予め定められた順番に従って、電力を供給する。
よって、複数の機器収納用ユニット２それぞれに、１台ずつ順番に電源ユニット３から電力を供給することで、機器収納用ユニット２の数に依らず、負荷電流の増加を抑えられるため、商用電源から受け取る電流を一定に保ち、過電流となることを防止できる。 The power supply unit 3 also has 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.

以上は、本発明を図示例に基づいて説明したものであり、その技術範囲はこれに限定されるものではない。
例えば、充電装置に組み込む機器収納用ユニットの台数は、電源ユニットの電源ユニット側電力供給部が接続可能な台数の範囲であれば、任意に設定可能である。一方、充電装置に組み込む機器収納用ユニットの台数に合わせて、電力ユニット側電力供給部の接続部の数を変更しても良い。
また、充電装置は、収納できる機器の規格が異なる複数の機器収納用ユニットを備えていても良い。
また、機器収納用ユニットと電源ユニットとの接続確認は、電流が流れるか否かでの判断に限定されず、例えば、電源ユニット側電力供給部の接続部にリミットスイッチ等を設け、ケーブルの接続を認識することで、電力の供給をするか否かを判断する等しても良い。
また、電源ユニット側電力供給部における各接続部への電力供給の切り替えタイミングは、タイマー制御に限定されず、例えば、機器の満充電が完了したことを判断した場合でも良いし、一定電流値まで充電を行った場合でも良いし、機器から何らかの信号を受け取る等した場合でも良い。
また、電源ユニットの充電制御部に加え、機器収納用ユニットにも充電制御部を設け、機器収納用ユニットの充電制御部から収納充電ポケット毎に順に充電が行われるような指示を出す構成としても良い。 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.
