【発明の属する技術分野】
本発明は、携帯電子機器用充放電器に関する。
【0002】
【従来の技術】
従来の充放電器は、陽極板と陰極板とが、極めて薄いセパレータを介して渦巻き状に巻き取られていて、短円柱形状の外装缶に収めたものが知られている(例えば、特許文献1参照)。上記特許文献1のものは、ニッケル・カドミウム蓄電池であるが、電気二重層コンデンサから成る充放電器も同様に短円柱形状の外装缶内に渦巻き状に陽極板と陰極板を積層状として、収納した構造であった。

【発明が解決しようとする課題】
このように短円柱形状の従来の(充放電器としての)電気二重層コンデンサを、携帯に便利なように偏平弁当箱形状や直方体箱形状の外ケースに収納して使用されていた。従って、二重のケースを必要として、構造が複雑化すると共に、無駄な空隙が外ケースと内ケース(二重層コンデンサ外装缶)との間に形成されて容積が増加するといった問題があり、重量アップとコストアップの原因にもなっていた。また、出力電圧・出力電流の変動を制御する装置が組み込まれていないため、例えば外出先等で電子機器に接続する場合、別途で電圧電流制御装置を携帯する必要があり、外部への持ち運びに不便である。
【0005】
そこで、本発明は、外出先等に持ち運び易いコンパクトな形状で、軽量であり、さらに、容易に大量生産を行うことの可能な携帯電子機器用充放電器を提供することを目的とする。

【0010】
【発明の実施の形態】
以下、実施の形態を示す図面に基づき、本発明を詳説する。
【0011】
図1は本発明の携帯電子機器用充放電器の実施の一形態を示す斜視図で、図2は断面平面図である。本発明に係る充放電器10は、電気エネルギを蓄える裸状の───外装缶を有さない───電気二重層コンデンサ部2と、電気二重層コンデンサ部2からの出力電圧の変動を平準化して出力電圧として外部へ出力するための電圧電流制御器3とを、同一のケース1に(一体状に)内蔵したものである。さらに、制御回路8と、危険防止回路9も、上記のケース1に(一体状に)内蔵され、図示省略するが、内蔵された夫々の部品は、配線,回路等にて接続されている。なお、上記電圧電流制御器3としては、定電圧・定電流を出力するためのものであって、DC−DCコンバータ及びツェナーダイオード(IC)等から成る。
【0012】
具体的には、ケース1は、前後方向細長の偏平弁当箱形状で、ケース1の前方部1aは、左右の角部をアール状に弯曲形成されている。ケース1の内部の前方は、電圧電流制御器3の出力側に相当する出力部18が形成されている。そして、開口凹部19が、ケース1の前方部1aに形成されていて、携帯電話や電動髭剃器等の電子機器に接続される端子部11を、開口凹部19に差し込めば、出力部18に接続可能である。
【0013】
従来のような外装缶を省略して、裸状の電気二重層コンデンサ部2は、複数の帯板状正電極板4…と、複数の帯板状負電極板5…とを、絶縁紙6…を間に挟んで交互に積層した偏平直方体形状である。なお、図2では理解し易いように、正負電極板4,5及び絶縁紙6の相互間に間隙を大きく描いているが、実際は、この間隙が生じないように積層されている。正電極板4…,負電極板5…,絶縁紙6…は、ケース1の底面に対して垂直状に、かつケース1の前後方向へ平行に配設されている。そして、接続板17が、全ての帯板状正電極板4…の端部に(共通に)接続してあり、別の接続板17が、全ての帯板状負電極板5…の端部に(共通に)接続している。
【0014】
ケース1の前方寄りの左右側面には、電力を入力する細長帯板状の2極の入力端子板7,7が付設されている。正電極板4…の端部に付設した共通の接続板17が連結された入力端子板7が、正極側7aであり、一方、負電極板5…の端部に付設した共通の接続板17が連結された入力端子板7が、負極側7bである。
【0015】
図3は他の実施の形態を示す断面平面図で、図1,図2に図示した電気二重層コンデンサ部2との相違点は、正電極板4…,負電極板5…,絶縁紙6…が、ケース1の左右方向へ平行に配設されている点である。なお、この図3でも、理解し易いように、正負電極板4,5及び絶縁紙6の相互間に間隙を大きく描いているが、実際は、この間隙が生じないように積層されている。
【0016】
ここで、電気二重層コンデンサ部2の製法の一例を説明すると、図4に示すように複数の正電極板4…の材料となるシート体4Aと、複数の負電極板5…の材料となるシート体5Aとを、絶縁紙6…の材料となるシート体6Aを中間に挟んで交互に積層する。シート体4A,5A,6Aは、いずれも十分に面積の大きいものである。そして、(図示省略の)切断機のカッター刃等で、切断線16のように切断すると、帯板状正電極板4…,帯板状負電極板5…,帯板状絶縁紙6…から成る偏平直方体形状の上記裸状の電気二重層コンデンサ部2が製造される。そして、図5に図示したように、電気二重層コンデンサ部2の正電極板4と負電極板5に、別々の接続板17,17を付設する。
【0017】
図6,図7に示すように、ケース1は、カバン,バッグ等に入れて持ち運べる大きさで、例えば、長さ寸法Dを10cm乃至15cmに、幅寸法Wを4cm乃至7cmに、高さ寸法Hを2cm乃至4cmに設定する。なお、図6に2点鎖線にて示すように、このケース1は、上下に2分割構造として、合せ目22にて合体化して、中空収納室を(図2と図3のように)形成するのがよい。この中空収納室には電解液を充填する。
【0018】
図8は、図1〜図3及び図6,図7に図示した充放電器10に充電する電力供給部12を示す説明用の平面図である。電力供給部12に、充放電器10の前方部1aが挿入される差込部12aが形成されている。そして、差込部12aの内部左右には、左右一対の電力供給端子板13,13が、挿入された充放電器10の入力端子板7,7に対応する位置に於て、内方へ弾発付勢するバネ15,15によって保持されている。電力供給端子板13,13は、充放電器10の幅寸法Wよりも狭く離間されていて、その先端部は、充放電器10の前方部1aを挿入し易いように、拡開して形成されている。
【0019】
図9は別の実施の形態を示す底面図で、図10は正面図である。図1〜図3及び図6,図7に図示した充放電器10との相違点は、ケース1の底面に、2極の左右一対の入力端子板7,7が付設されている点である。入力端子板7,7は、前後方向に細長の帯板状である。入力端子板7,7は、一方が正極側7aで、他方が負極側7bである。
【0020】
図11は、図9,図10に図示した充放電器10に充電する電力供給部12を示す説明用の正面図である。電力供給部12の正面に、充放電器10の前方部1aが挿入される差込部12aが凹設されている。そして、挿入された充放電器10の入力端子板7,7に対応する位置に於て、電力供給端子14,14が、上方へ弾発付勢するバネ15,15によって、差込部12aの下方内部に形成された孔部から突出するよう保持されている。
【0021】
図12は、横軸に時間Tを示し、縦軸に充放電器10から出力される電圧の関係を示したグラフ図である。電気二重層コンデンサ部2からの出力電圧は、2点鎖線にて示すV1 のように、出力開始時が最大で、時間Tの経過と共に急激に下がっていく。この出力電圧V1 が、電圧電流制御器3によって変動を制御され、出力電圧は、V0 に示したように、時間Tが経過しても、設定電圧電流値に保たれる。
【0022】
次に、充放電器10の作用(使用)について説明する。図8に於て、充放電器10の前方部1aを、電力供給部12の差込部12aに挿入すると、弾発付勢するバネ15,15によって、左右一対の電力供給端子板13,13が、充放電器10の入力端子板7,7に確実に当接し、電気エネルギが、入力端子板7,7及び接続板17,17を介して、電気二重層コンデンサ部2へと供給される。ここで、電力供給端子板13,13の先端部が、拡開して形成されており、また、ケース1の前方部1aは、左右の角部をアール状に弯曲形成されているので、充放電器10をスムースに差込可能である。なお、図例のケース1を設計変更して、電子機器に接続される端子部11を挿入する開口凹部19を、ケース1の後方部に形成して、電圧電流制御器3を有する出力部18を、ケース1の内部の後方に付設してもよい。
【0023】
また、図11に於ても、充放電器10の前方部1aを、電力供給部12の差込部12aに挿入すると、上方へ弾発付勢するバネ15,15によって、電力供給端子14,14が、充放電器10の入力端子板7,7に確実に当接し、電気二重層コンデンサ部2が充電される。
【0024】
電気二重層コンデンサ部2(充放電器10)への充電を終えたら、充放電器10を電力供給部12から外して、カバンやバッグに入れ、携帯して持ち運ばれる。そして、移動先で、携帯電話や電動髭剃器等の電子機器に接続した端子部11を、充放電器10の出力部18に接続すると、充放電器10の電気二重層コンデンサ部2に蓄えられた電気エネルギが、電子機器へと供給される。ここで、図12に於て説明したように、電子機器へは、電圧電流制御器3によってV0 に示したように所定の設定電圧電流値に制御された一定の電圧電流が、長時間にわたり供給される。
【0025】
このように、充放電器10は、従来の外装缶を有さない───裸状の───電気二重層コンデンサ部2と、電圧電流制御器3とを、同一ケース1に内蔵したものであるので、一体物の充放電器10によって、予め電気エネルギを蓄え、その電気エネルギを一定の出力電圧にして、電子機器に供給できる。そして、持ち運びにも便利である。ケース1は偏平弁当箱形状なので、ケース1内に無駄なスペースを作らずに、電気二重層コンデンサ部2,電圧電流制御器3等の部品を内蔵でき、軽量化を図って、コンパクトな大きさ,形状に作製できる。
また、ケース1の形状は実施例に限定されず、設計変更可能で、ケース1に装飾を施したり、デザインすることで、充放電器10を携帯する楽しみを増やすことも可能である。
【0026】
裸状の電気二重層コンデンサ部2は、偏平直方体形状なので、上記のケース1内にコンパクトに内蔵することができる。さらに、図4に於て説明したように、正電極板4,負電極板5,絶縁紙6の材料となるシート体を何層にも積層し、切断機で切断するだけで、容易に本発明のような電気二重層コンデンサ部2を製造できるので、従来のように、コイル状に巻き付けていく等の手間が少なくなり、容易に大量生産できる。
【0027】
また、入力端子板7,7が、ケース1の左右側面に付設されており、図8にて説明した電力供給部12に差し込むだけで、容易に充電することができる。入力端子板7,7が、ケース1の底面に付設されていても同様で、図11にて説明した電力供給部12に差し込むだけで、容易に充電することができる。そして、ケース1は偏平弁当箱形状で、ケース1の前方部1aは、左右の角部をアール状に弯曲形成されており、差し込む向き,方向を容易に分別できるので、電力供給部12に接続する際に、入力端子板7,7の正極側7aと負極側7bを間違えることはない。また、端子が突状ではないので、持ち運ぶ際に邪魔にならない。
【0028】
【発明の効果】
本発明は、上述の構成により次のような著大な効果を奏する。
【0029】
(請求項1, 2,3,4によれば、)ケース1内に無駄なスペースを作らずに、電気二重層コンデンサ部2,電圧電流制御器3等の部品を内蔵できる。そして、ケース1は一重で済み、軽量化と構造の簡素化を図り得る。そして、コンパクトな大きさ,形状に作製できるので、一体物の充放電器によって、予め電気エネルギを蓄え、その電気エネルギを一定の出力電圧にして、電子機器に供給できる。このように、充放電器を、カバンやバッグに入れて携帯して持ち運び易く、出先で必要な時に、いつでも電子機器に出力電圧を供給することができて便利である。
【0030】
また、電気二重層コンデンサ部2は、裸状で偏平直方体形状なので、上記のケース1内にコンパクトに内蔵することができ、一層充放電器のコンパクト化を図ることができる。さらに、正電極板4,負電極板5,絶縁紙の材料となるシート体を何層にも積層し、切断機で切断するだけで電気二重層コンデンサ部2を製造できるので、容易に大量生産できる。
【0031】
さらに、電力供給部12へ差し込んで、簡便に充電ができる。
