【００１０】
【発明の実施の形態】
以下、本発明を、外出先等で携帯電話機の内蔵電池を充電するための携帯電話機用携帯型充電器（以下、単に「充電器」という。）に適用した一実施形態について説明する。
図１は、本実施形態に係る充電器を充電するときの状態の概略構成を示す外観図である。この充電器１０は、第１の接続部としての第１コネクタ１１と、第２の接続部としての第２コネクタ１２とを備えている。また、内部には、３本の２次電池１３を着脱可能に収容するソケット部１４が設けられている。なお、図示の充電器１０は、ソケット部１４の蓋が開いた状態を示している。この充電器１０内の２次電池１３は、携帯電話機１の内蔵電池と同じ充電作業で充電することができる。両者を充電する場合には、第１コネクタ１１に携帯電話機１の外部コネクタ２を接続し、かつ、第２コネクタ１２にその携帯電話機１の専用充電器２０の電圧供給用コネクタである専用コネクタ２１を接続する。専用充電器２０の電源コネクタ２２は、自宅の電源コンセント３０に差し込まれる。なお、携帯電話機１のみを充電する場合には、従来と同様に、専用充電器２０の専用コネクタ２１を携帯電話機１の外部コネクタ２に直接接続してもよい。
【００１１】
ここで、携帯電話機１の外部コネクタ２は、一般にメスコネクタであり、そのコネクタ形状は携帯電話機１の種類ごとに異なっている。本実施形態の第１コネクタ１１には、すべての外部コネクタ２に対応した形状をもつ公知の汎用オスコネクタが利用されている。
一方、携帯電話機１に付属の専用充電器２０に設けられる専用コネクタ２１は、その携帯電話機１の外部コネクタ２に対応した形状を有するオスコネクタであり、そのコネクタ形状は携帯電話機１の種類ごとに異なっている。本実施形態の第２コネクタ１２には、すべての専用コネクタ２１に対応した形状をもつメスコネクタが利用されている。また、本実施形態の第２コネクタ１２の形状は、特定の携帯電話機に専用のものではない公知の汎用オスコネクタの形状にも対応している。具体的には、この第２コネクタ１２の内形形状は、すべての専用コネクタ２１及び汎用オスコネクタが有するいずれの外形にも衝突することのない最小範囲に決められている。そして、その第２コネクタ１２には、いずれのオスコネクタが挿入されたときでもオスコネクタとの連結状態を保持する保持手段が設けられている。本実施形態では、第２コネクタ１２の内壁の適切な位置に設けられる突起部が保持手段として機能している。
なお、本実施形態では、携帯電話機１に付属する専用充電器２０を利用しているが、本充電器１０に専用の電源ケーブルを用意するのであれば、第２コネクタ１２はこの電源ケーブルと接続できるものであればよい。また、第２コネクタ１２として、電源コンセント３０に直接差し込むことができる電源コネクタを利用することもできる。
【００１２】
図２は、充電器１０の内部の回路構成を示すブロック図である。この充電器１０は、第２コネクタ１２を介して専用充電器２０から供給された外部電圧から所望の定電圧を得るための定電圧回路部１５を備えている。この定電圧回路部１５は、外部電圧が入力されると、下段の回路部に一定の電圧（ＤＣ４．５Ｖ）を供給する。
【００１３】
この定電圧回路部１５から出力される一定電圧は、２次電池充電手段としての２次電池充電部１６に入力される。この２次電池充電部１６は、２次電池１３が装着されたソケット部１４によって構成されている。２次電池充電部１６は、入力された一定電圧が加わることによって流れる電流により２次電池１３を充電する。
また、定電圧回路部１５からの一定電圧は、充電電圧供給手段としての昇圧回路部１７にも入力される。この昇圧回路部１７は、入力された一定電圧を携帯電話機１の内蔵電池の充電に必要な電圧に変圧した後、その電圧を第１コネクタ１１に供給する。なお、本実施形態では、内部に充電回路を備えた携帯電話機１の充電を例に挙げているので、昇圧回路部１７では、入力されるＤＣ４．５ＶをＤＣ５．４Ｖまで昇圧している。このように昇圧された電圧は、第１コネクタ１１に接続されている外部コネクタ２を介して、その携帯電話機１の充電回路に送られ、その充電回路により内蔵電池が充電される。このように、本実施形態における回路構成によって外部電圧供給手段が構成されている。
なお、外出先等において、本充電器１０の２次電池１３で発生する電圧によって携帯電話機１の内蔵電池を充電する場合、２次電池１３で発生する電圧が昇圧回路部１７に入力される。そして、昇圧回路部１７は、上記と同様に、入力された電圧を変圧した後、その電圧を第１コネクタ１１に供給する。これにより、携帯電話機１の充電回路が内蔵電池を充電する。
【００１４】
次に、本充電器１０の動作について説明する。
図３は、本実施形態における充電器１０の動作を示すフローチャートである。本充電器１０は、第１コネクタ１１及び第２コネクタ１２の電気的な接続状態の違いにより、その動作が異なる。
第１コネクタ１１が携帯電話機１に内蔵された充電回路と電気的に接続された状態（以下、単に「接続状態」という。）であり、かつ、第２コネクタ１２が専用充電器２０と電気的に接続されていない状態（以下、単に「非接続状態」という。）である場合（Ｓ１）、昇圧回路部１７には、２次電池１３で発生する電圧が入力される。そして、本充電器１０の２次電池１３から携帯電話機１の充電回路に電流が流れ込み、内蔵電池が充電される（Ｓ２）。内蔵電池の充電が終了すると、携帯電話機１の充電回路によって携帯電話機１に流れ込む電流がカットされるため、２次電池１３からは電流が供給されなくなり、充電が終了する。
【００１５】
また、第１コネクタ１１が携帯電話機１の充電回路と非接続状態であり、かつ、第２コネクタ１２が専用充電器２０と接続状態である場合（Ｓ３）、２次電池充電部１６には、第２コネクタ１２からの外部電圧が入力される。これにより、その第２コネクタ１２から２次電池充電部１６に電流が流れ込み、２次電池１３が充電される（Ｓ４）。このとき、第１コネクタ１１は非接続状態であるため、昇圧回路部１７には、電流が流れ込むことはない。
【００１６】
また、第１コネクタ１１及び第２コネクタ１２がともに接続状態である場合（Ｓ５）、２次電池充電部１６及び昇圧回路部１７には、第２コネクタ１２からの外部電圧が入力される。第２コネクタ１２から流入する電流は、インピーダンスの関係で、そのほとんどは、２次電池充電部１６には流れ込まずに昇圧回路部１７に流れ込むことになる。これにより、携帯電話機１の充電回路によって内蔵電池が充電される（Ｓ６）。内蔵電池の充電が終了すると、上述のように携帯電話機１に流れ込む電流がカットされるため、第２コネクタ１２から流入する電流は、今度は２次電池充電部１６には流れ込み、２次電池１３が充電される（Ｓ７）。
【００１７】
また、本実施形態の２次電池１３として、単４形のＮｉ−ＭＨ電池を用いているので、ソケット部１４に単４形の１次電池を装着して利用することもできる。これにより、例えば外出先等において２次電池を使い切ってしまったときでも、１次電池を利用して携帯電話機１の内蔵電池の充電作業を行うことができる。このとき、１次電池が装着された状態で、２次電池充電部１６による充電動作が行われない構成とするのが望ましい。例えば、ソケット部１４の構造を、２次電池１３を装着したときと１次電池を装着したときとで、その接触端子が互いに異なるようにする構成する。なお、ソケット部１４を設けずに、本充電器１０に対して着脱できない内蔵型の２次電池を用いてもよい。
【００１８】
以上、本実施形態によれば、携帯電話機１を接続した状態の充電器１０に、その携帯電話機１に付属の専用充電器２０を接続するだけで、その携帯電話機１の内蔵電池及び充電器１０の２次電池の充電を一度に済ますことができる。よって、従来別々に行わなければならなかった両者の充電作業を一度に行うことができるので、その利便性を高めることができる。
なお、本実施形態では、携帯電話機１の内蔵電池の充電を優先して行う構成としたが、２次電池１３の充電を優先して行ったり、内蔵電池と２次電池１３の充電を同時に行ったりしてもよい。
【００１９】
【発明の効果】
請求項１乃至５の発明によれば、本携帯形充電器内の２次電池を充電する作業を携帯電話機の充電作業とは別個に行う必要がなくなるため、２次電池の充電作業の煩雑さをなくし、２次電池を使用するタイプの携帯型充電器の利便性を高めることができるという優れた効果がある。
特に、請求項２の発明によれば、利用者に優先的に使用される携帯電話機の内蔵電池を先に充電するので、さらに利便性を高めることができるという優れた効果がある。
また、請求項３の発明によれば、本携帯型充電器専用の電圧供給用コネクタを別個用意する必要がなくなるので、生産コストを抑えることができるという優れた効果がある。
また、請求項４の発明によれば、携帯電話機の種類ごとに異なる接続部を用意する必要がなくなるので、生産コストをさらに抑えることができるという優れた効果がある。
また、請求項５の発明によれば、１次電池を利用することでも携帯電話機の内蔵電池を充電できるので、さらに利便性を高めることができるという優れた効果がある。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment will be described in which the present invention is applied to a portable charger for a portable telephone (hereinafter, simply referred to as a “charger”) for charging a built-in battery of the portable telephone at a place where the user is away.
FIG. 1 is an external view showing a schematic configuration of a state when charging the charger according to the present embodiment. This charger 10 includes a first connector 11 as a first connection portion, and a second connector 12 as a second connection portion. Further, a socket portion 14 for detachably housing three secondary batteries 13 is provided inside. Note that the illustrated charger 10 shows a state where the lid of the socket portion 14 is open. The secondary battery 13 in the charger 10 can be charged by the same charging operation as the built-in battery of the mobile phone 1. When charging both, the external connector 2 of the mobile phone 1 is connected to the first connector 11 and the dedicated connector 21 which is a voltage supply connector of the dedicated charger 20 of the mobile phone 1 is connected to the second connector 12. Connect. The power connector 22 of the dedicated charger 20 is inserted into a power outlet 30 at home. When only the mobile phone 1 is charged, the dedicated connector 21 of the dedicated charger 20 may be directly connected to the external connector 2 of the mobile phone 1 as in the related art.
[0011]
Here, the external connector 2 of the mobile phone 1 is generally a female connector, and the connector shape is different for each type of the mobile phone 1. As the first connector 11 of the present embodiment, a known general-purpose male connector having a shape corresponding to all the external connectors 2 is used.
On the other hand, the dedicated connector 21 provided in the dedicated charger 20 attached to the mobile phone 1 is a male connector having a shape corresponding to the external connector 2 of the mobile phone 1, and the connector shape is different for each type of the mobile phone 1. Is different. As the second connector 12 of the present embodiment, a female connector having a shape corresponding to all dedicated connectors 21 is used. Further, the shape of the second connector 12 of the present embodiment also corresponds to the shape of a known general-purpose male connector that is not dedicated to a specific mobile phone. Specifically, the inner shape of the second connector 12 is determined to be a minimum range that does not collide with any of the external shapes of all the dedicated connectors 21 and the general-purpose male connector. The second connector 12 is provided with holding means for holding the connected state with the male connector even when any of the male connectors is inserted. In the present embodiment, a protrusion provided at an appropriate position on the inner wall of the second connector 12 functions as a holding unit.
In this embodiment, the dedicated charger 20 attached to the mobile phone 1 is used. However, if a dedicated power cable is provided for the charger 10, the second connector 12 is connected to the power cable. Anything that can be done is acceptable. Further, a power connector that can be directly inserted into the power outlet 30 can be used as the second connector 12.
[0012]
FIG. 2 is a block diagram showing a circuit configuration inside charger 10. The charger 10 includes a constant voltage circuit section 15 for obtaining a desired constant voltage from an external voltage supplied from the dedicated charger 20 via the second connector 12. When an external voltage is input, the constant voltage circuit section 15 supplies a constant voltage (DC 4.5 V) to the lower circuit section.
[0013]
The constant voltage output from the constant voltage circuit unit 15 is input to a secondary battery charging unit 16 as a secondary battery charging unit. The secondary battery charging section 16 includes a socket section 14 in which the secondary battery 13 is mounted. The secondary battery charging unit 16 charges the secondary battery 13 with a current flowing when the input constant voltage is applied.
Further, the constant voltage from the constant voltage circuit unit 15 is also input to a booster circuit unit 17 as a charging voltage supply unit. The booster circuit section 17 converts the input constant voltage to a voltage required for charging the internal battery of the mobile phone 1, and supplies the voltage to the first connector 11. In the present embodiment, the charging of the mobile phone 1 having a charging circuit therein is taken as an example. Therefore, the booster circuit unit 17 boosts the input DC 4.5V to DC 5.4V. The boosted voltage is sent to the charging circuit of the mobile phone 1 via the external connector 2 connected to the first connector 11, and the built-in battery is charged by the charging circuit. As described above, the external voltage supply unit is configured by the circuit configuration according to the present embodiment.
When the built-in battery of the mobile phone 1 is charged by the voltage generated by the secondary battery 13 of the battery charger 10 when going out, the voltage generated by the secondary battery 13 is input to the booster circuit unit 17. Then, similarly to the above, the booster circuit section 17 converts the input voltage and supplies the voltage to the first connector 11. Thereby, the charging circuit of the mobile phone 1 charges the built-in battery.
[0014]
Next, the operation of the present charger 10 will be described.
FIG. 3 is a flowchart showing the operation of the charger 10 in the present embodiment. The operation of the charger 10 differs depending on the difference in the electrical connection between the first connector 11 and the second connector 12.
The first connector 11 is in a state of being electrically connected to a charging circuit built in the mobile phone 1 (hereinafter, simply referred to as a “connection state”), and the second connector 12 is electrically connected to the dedicated charger 20. (Hereinafter simply referred to as “disconnected state”) (S1), the voltage generated by the secondary battery 13 is input to the booster circuit section 17. Then, current flows from the secondary battery 13 of the charger 10 to the charging circuit of the mobile phone 1, and the built-in battery is charged (S2). When the charging of the built-in battery is completed, the current flowing into the mobile phone 1 is cut by the charging circuit of the mobile phone 1, so that no current is supplied from the secondary battery 13 and the charging ends.
[0015]
When the first connector 11 is not connected to the charging circuit of the mobile phone 1 and the second connector 12 is connected to the dedicated charger 20 (S3), the secondary battery charger 16 includes: An external voltage is input from the second connector 12. As a result, a current flows from the second connector 12 to the secondary battery charging section 16, and the secondary battery 13 is charged (S4). At this time, since the first connector 11 is not connected, no current flows into the booster circuit unit 17.
[0016]
When the first connector 11 and the second connector 12 are both connected (S5), an external voltage from the second connector 12 is input to the secondary battery charger 16 and the booster circuit 17. Most of the current flowing from the second connector 12 flows into the booster circuit unit 17 without flowing into the secondary battery charging unit 16 because of the impedance. Thus, the built-in battery is charged by the charging circuit of the mobile phone 1 (S6). When the charging of the built-in battery is completed, the current flowing into the mobile phone 1 is cut as described above, so that the current flowing from the second connector 12 flows into the secondary battery charging unit 16 this time, and the secondary battery 13 Is charged (S7).
[0017]
Further, since the Ni-MH battery of the AAA type is used as the secondary battery 13 of the present embodiment, a AAA type primary battery can be mounted on the socket portion 14 for use. Thus, even when the secondary battery is used up, for example, when going out, the charging operation of the internal battery of the mobile phone 1 can be performed using the primary battery. At this time, it is preferable that the charging operation by the secondary battery charging unit 16 is not performed in a state where the primary battery is mounted. For example, the structure of the socket part 14 is configured such that the contact terminals thereof are different between when the secondary battery 13 is mounted and when the primary battery is mounted. Note that a built-in secondary battery that cannot be attached to and detached from the charger 10 may be used without providing the socket portion 14.
[0018]
As described above, according to the present embodiment, the built-in battery and the charger 10 of the mobile phone 1 can be connected to the charger 10 to which the mobile phone 1 is connected simply by connecting the dedicated charger 20 attached to the mobile phone 1. Can be charged all at once. Therefore, since both charging operations, which had to be performed separately in the past, can be performed at once, the convenience can be improved.
In this embodiment, charging of the internal battery of the mobile phone 1 is performed with priority. However, charging of the secondary battery 13 is performed with priority, or charging of the internal battery and the secondary battery 13 is performed simultaneously. Or you may.

【The invention's effect】
According to the first to fifth aspects of the present invention, the work of charging the secondary battery in the portable charger does not need to be performed separately from the work of charging the mobile phone, so that the work of charging the secondary battery is complicated. And there is an excellent effect that the convenience of a portable charger using a secondary battery can be improved.
In particular, according to the second aspect of the present invention, the built-in battery of the mobile phone used preferentially by the user is charged first, so that there is an excellent effect that the convenience can be further improved.
Further, according to the third aspect of the present invention, there is no need to separately prepare a voltage supply connector dedicated to the portable charger, so that there is an excellent effect that the production cost can be reduced.
Further, according to the invention of claim 4, since it is not necessary to prepare a different connection unit for each type of mobile phone, there is an excellent effect that the production cost can be further reduced.
Further, according to the invention of claim 5, since the built-in battery of the mobile phone can be charged even by using the primary battery, there is an excellent effect that the convenience can be further improved.
