前記挿脱口を開閉するように前記本体部に対して開閉動作可能に設けられた開閉部と、
ケース側接続端子と、を備え、
前記バッテリ収容部には、バッテリ側接続端子を有するバッテリが前記挿脱口から挿脱可能に収容され、
前記ケース側接続端子は、前記バッテリ側接続端子と接続する接続位置と、前記バッテリ側接続端子から離間した退避位置と、の間で変位可能に設けられている、バッテリ収容装置であって、
前記バッテリ収容装置は、前記ケース側接続端子を前記接続位置と前記退避位置との間で変位させる接続端子変位機構をさらに備え、
前記接続端子変位機構は、前記開閉部の開閉動作に連動して、前記ケース側接続端子を変位させる。
バッテリ80は、上下方向に長い略四角柱形状を有する。バッテリ80の上面80Uには、把持部81が設けられている。把持部81は上面80Uの左右方向略中央で、前後方向に延在している。
図1から図4に示すように、バッテリ収容装置10は、本体ユニット20と、開閉ユニット30と、ケース側接続端子ユニット40と、接続端子変位機構50と、バックルユニット60と、を備える。なお、図3は、開閉ユニット30が全開位置にあるときを示した図であり、図4は、開閉ユニット30が全閉位置にあるときを示した図である。
本体ユニット20は、(前後方向寸法)<(左右方向寸法)<(上下方向寸法)の略四角柱形状を有する。本体ユニット20は、前面20F、後面20B、左面20L、右面20R、上面20U、及び底面20D、を有する。
開閉ユニット30は、挿脱口241を開閉するように、本体ユニット20対して開閉動作可能に設けられている。開閉ユニット30は、本体ユニット20の各バッテリ収容部24に1つ設けられている。本実施形態では、本体ユニット20には、バッテリ収容部24が左右方向に並んで2つ設けられているので、開閉ユニット30も左右方向に並んで2つ設けられている。各開閉ユニット30は、開閉ユニット30の骨格部を構成するカバーフレーム31と、ヒンジシャフト32と、カバーフレーム31に固定された押圧部材33と、開閉ユニット30の外殻を構成するトップカバー34と、を備える。
ケース側接続端子ユニット40は、本体ユニット20の内部に収容されている。ケース側接続端子ユニット40は、バッテリ収容ケース23の底壁部23Dに設けられた挿通孔232を挿通してバッテリ側接続端子ユニット90に嵌合可能な入力プラグ41と、入力プラグ41を保持するプラグホルダ42と、を備える。
図2から図5に示すように、接続端子変位機構50は、ケース側接続端子ユニット40を上下方向に変位させるリンク機構51と、開閉ユニット30の回動を減速してリンク機構51に伝達する減速装置52と、を備える。本実施形態では、接続端子変位機構50は、2つ設けられている。詳細には、本実施形態では、ケース側接続端子ユニット40は、左右方向に並んで2つ設けられており、接続端子変位機構50は、左側のケース側接続端子ユニット40を上下方向に変位させる接続端子変位機構50Lと、右側のケース側接続端子ユニット40を上下方向に変位させる接続端子変位機構50Rと、を有する。接続端子変位機構50Lと、接続端子変位機構50Rとは、左右対称の構造となっている。以下、接続端子変位機構50Lと接続端子変位機構50Rとを区別する必要がない場合には、接続端子変位機構50と記載する。
図1から図4に示すように、バックルユニット60は、本体ユニット20の前端で、回動軸心が左右方向に延在するように、本体フレーム21に回動可能に軸支されている。バックルユニット60は、各開閉ユニット30に1つ設けられている。本実施形態では、開閉ユニット30が左右方向に並んで2つ設けられているので、バックルユニット60も左右方向に並んで2つ設けられている。
次に、開閉ユニット30の開閉動作によるケース側接続端子ユニット40の変位動作について、図3及び図4を参照しながら説明する。なお、図3及び図4においては、接続端子変位機構50として、左側のケース側接続端子ユニット40を上下方向に変位させる接続端子変位機構50Lの動作について説明する。右側のケース側接続端子ユニット40を上下方向に変位させる接続端子変位機構50Rの動作は、接続端子変位機構50Lと左右対称であるため、詳細な説明は省略する。
図3に示すように、開閉ユニット30が全開位置にあるとき、ケース側接続端子ユニット40の入力プラグ41は、退避位置P1に位置する。退避位置P1は、バッテリ80が本体ユニット20のバッテリ収容部24に収容され、バッテリ80の底面80Dがバッテリ収容ケース23の底壁部23Dに当接した状態において、ケース側接続端子ユニット40のプラスマイナス一対の入力端子ピン411、複数の信号端子ピン412、及び左右一対のガイドピン413が、対になるバッテリ側接続端子ユニット90の出力端子ソケット91、信号端子ソケット92、及びガイド穴93から離間した位置であり、ケース側接続端子ユニット40の入力プラグ41が、バッテリ収容ケース23の底壁部23Dよりも下方となる位置である(図8A参照)。
図4に示すように、開閉ユニット30を全閉位置から開動作させると、開閉ユニット30は、ヒンジシャフト32を回動軸心として本体ユニット20に対して後方、すなわち、左方向から見て反時計回り方向に回動する。
次に、ケース側接続端子ユニット40の変位動作時における開閉ユニット30と入力プラグ41との位置関係について、図7及び図8A~図8Dを参照しながら説明する。
図7の(a)、及び図8Aに示すように、開閉ユニット30が全開位置にあるとき、ケース側接続端子ユニット40の入力プラグ41は、退避位置P1に位置する。退避位置P1は、バッテリ80が本体ユニット20のバッテリ収容部24に収容され、バッテリ80の底面80Dがバッテリ収容ケース23の底壁部23Dに当接した状態において、ケース側接続端子ユニット40のプラスマイナス一対の入力端子ピン411、複数の信号端子ピン412、及び左右一対のガイドピン413が、対になるバッテリ側接続端子ユニット90の出力端子ソケット91、信号端子ソケット92、及びガイド穴93から離間した位置であり、ケース側接続端子ユニット40の入力プラグ41が、バッテリ収容ケース23の底壁部23Dよりも下方となる位置である。
図7の(b)及び図8Bに示すように、開閉ユニット30の閉動作が進行して、ケース側接続端子ユニット40の上方への変位が進行すると、まず、ケース側接続端子ユニット40の入力プラグ41に設けられた左右一対のガイドピン413が、バッテリ側接続端子ユニット90の対になるガイド穴93に嵌入する。これにより、ケース側接続端子ユニット40の入力プラグ41と、バッテリ側接続端子ユニット90とが位置決めされる。
図7の(c)及び図8Cに示すように、開閉ユニット30の閉動作がさらに進行して、ケース側接続端子ユニット40の上方への変位がさらに進行すると、ケース側接続端子ユニット40の入力プラグ41は、接続位置P2まで変位する。そして、ケース側接続端子ユニット40の入力プラグ41に設けられた左右一対の入力端子ピン411及び複数の信号端子ピン412は、バッテリ側接続端子ユニット90のそれぞれ対になる出力端子ソケット91及び信号端子ソケット92に嵌合接続された状態となる。
図7の(d)及び図8Dに示すように、開閉ユニット30の閉動作がさらに進行すると、プラグホルダ42のフレーム部材421及び連結ピン422はさらに上方に変位して、開閉ユニット30は全閉位置となる。このとき、スプリングユニット423のストッパプレート423bは連結ピン422とともに上方に変位するが、入力プラグ41は接続位置P2から変位せずに、スプリングユニット423のコイルスプリング423cが圧縮される。そして、開閉ユニット30が全閉状態にあるとき、入力プラグ41は、圧縮されたコイルスプリング423cによってバッテリ80のバッテリ側接続端子ユニット90に向かって付勢された状態で、接続位置P2に保持される。
また、開閉ユニット30は、全開位置及び全閉位置のいずれかの位置で保持されるため、ユーザ等が開閉ユニット30を閉動作させるときに、全閉位置に至る前の位置で停止することを抑制できるため、バッテリ側接続端子ユニット90とケース側接続端子ユニット40とが不完全な嵌合接続状態となることを抑制でき、ひいては不完全な嵌合接続状態で外部負荷を起動することを抑制できる。
また、開閉ユニット30は、全開位置及び全閉位置のいずれかの位置で保持されるため、ユーザ等が開閉ユニット30を閉動作させるときに、全閉位置に至る前の位置で停止することを抑制できるため、外部から雨や埃等がバッテリ収容部24に侵入することを防止できる。
