Description

【０００１】
【発明の属する技術分野】
本発明は、モータによって後輪を駆動する電動二輪車に関するものである。
【０００２】
【従来の技術】
従来の電動二輪車は、エンジン駆動式自動二輪車の動力ユニットを電動化することによって構成されている（例えば、特許文献１参照）。この種の電動二輪車は、車体フレームなどの車体の骨格をなす部材がエンジン駆動式の自動二輪車と同等に形成されており、エンジン駆動式の自動二輪車においてエンジンが搭載されている位置にモータが配設され、このモータの近傍にバッテリーが配設されていた。また、従来の電動二輪車は、燃料タンクが不要になることから、エンジン駆動式自動二輪車において燃料タンクが搭載されていた部分に別の部品が取付けられたり、収納スペースが形成されたりすることが多かった。
なお、本出願人は、本明細書に記載した先行技術文献情報で特定される先行技術文献以外には、本発明に関連する先行技術文献を出願時までに発見するには至らなかった。
【０００３】
【特許文献１】
特許第３２４７９８９号公報（第２−５頁、第１−６図）
【０００４】
【発明が解決しようとする課題】
しかしながら、上述したようにエンジン駆動式自動二輪車の基本的な骨格を流用して電動二輪車を形成するに当たっては、燃料タンクが操向ハンドルとシートとの間に位置している場合に問題が生じた。これは、燃料タンクが操向ハンドルとシートとの間に設けられている車両は、乗員が両脚で燃料タンクを挾み、いわゆるニーグリップによって上体を安定させることがあるからである。すなわち、電動化するに当たって燃料タンクが別の部品に換えられてしまうと、ニーグリップが行い難くなるおそれがあるからである。
【０００５】
本発明はこのような問題点を解消するためになされたもので、燃料タンクが操向ハンドルとシートとの間に位置するエンジン駆動式自動二輪車を電動化できるようにすることを目的とする。
【０００６】
【課題を解決するための手段】
この目的を達成するため、本発明に係る電動二輪車は、操向ハンドルとシートとの間にエンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されて電動二輪車用用部品を覆う被覆部材を設け、この被覆部材の上端部に開口部を形成し、この開口部にエンジン駆動式自動二輪車の燃料タンク用蓋体と同等の形状に形成された蓋体を開閉自在に設け、前記被覆部材における蓋体を開くことにより露出する部位に充電用コネクタを設けたものである。
【０００７】
本発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。また、前記被覆部材と蓋体との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等の防水構造を採ることができるから、水に濡れてはならない充電用コネクタが収納されている被覆部材内に雨水などが浸入するのを確実に阻止することができる。
【０００８】
請求項２に記載した発明に係る電動二輪車は、操向ハンドルとシートとの間にエンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されて電動二輪車用用部品を覆う被覆部材を設け、この被覆部材の上端部に開口部を形成し、この開口部にエンジン駆動式自動二輪車の燃料タンク用蓋体と同等の形状に形成された蓋体を開閉自在に設け、前記被覆部材の内部にバッテリー収納空間を形成したものである。
この発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。また、前記被覆部材と蓋体との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等の防水構造を採ることができるから、水に濡れてはならないバッテリーが収納される被覆部材内に雨水などが浸入するのを確実に阻止することができる。
【０００９】
請求項３に記載した発明に係る電動二輪車は、請求項２に記載した発明に係る電動二輪車において、被覆部材とシートとを車体フレームに上下方向に着脱自在に設け、これらの被覆部材とシートの下方に車体の前後方向に長いバッテリーを収納し、前記被覆部材とシートは、前記バッテリーを収納する空間の蓋を構成しているものである。
この発明によれば、容量が相対的に多いバッテリーを被覆部材とシートとの下方に収納することができる。このバッテリーは、前記被覆部材とシートとを車体フレームから取外すことによって上方に向けて露出するから、充電時などで簡単に着脱することができる。
【００１０】
請求項４に記載した発明に係る電動二輪車は、操向ハンドルとシートとの間にエンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されて電動二輪車用用部品を覆う被覆部材を設け、この被覆部材の下方にモータ制御用のコントローラを配設したものである。
【００１１】
この発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。また、この電動二輪車は、コントローラに走行風が当たり易くなり、しかも、外観がエンジン駆動式自動二輪車と同等になるように形成することができる。
【００１２】
【発明の実施の形態】
以下、本発明に係る電動二輪車の一実施の形態を図１ないし図４によって詳細に説明する。
図１は本発明に係る電動二輪車の側面図、図２は同じく平面図、図３は同じく背面図である。図４は図１における動力ユニットのＩＶ−ＩＶ線断面図である。
【００１３】
これらの図において、符号１で示すものは、この実施の形態による電動二輪車である。この電動二輪車１は、オフロードを走行するためのもので、子供でも乗車できるように、前輪２と後輪３として相対的に小径のものが用いられている。また、この電動二輪車１の外観部材は、後述する駆動系の動力ユニットの他はエンジン駆動式自動二輪車と外観形状が同一になるように形成されている。前記前輪２は、フロントフォーク４の下端部に回転自在に取付けられ、このフロントフォーク４は、上端部に操向ハンドル５が設けられ、後述する車体フレーム６のヘッドパイプ７に回動自在に支持されている。前記後輪３は、後述する動力ユニット８の後端部に回転自在に装着されている。
【００１４】
前記車体フレーム６は、前記ヘッドパイプ７から車幅方向の中央部で後下がりに延びるメインパイプ９と、このメインパイプ９から動力ユニット８と前輪２との間を通って下方へ延び、下端部が動力ユニット８の下方へ延びる左右一対のダウンチューブ１０と、前記メインパイプ９の後端部から車体の後方に延びるシートレール１１と、このシートレール１１の途中から前下がりに延びて前記ダウンチューブ１０の後端に接続されたバックステー１２などによって構成されている。
【００１５】
前記バックステー１２は、１本のパイプを所定の形状に曲げることによって形成されており、動力ユニット８の後述するモータ１３の下方で車幅方向へ延びる車幅方向延在部１２ａ（図４参照）と、図１に示すように、前記車幅方向延在部１２ａの両端部からモータ１３の両側方を通って後上がりに延びる左右一対の上下方向延在部１２ｂとから構成されている。このバックステー１２の前記上下方向延在部１２ｂは、下端部にフートレスト１４が取付けられている。
【００１６】
前記車体フレーム６の上部（メインパイプ９およびシートレール１１）には、シート１５と、このシート１５と前記操向ハンドル５との間に位置する被覆部材１６と、シート１５の下方に位置するバッテリボックス１７などが装着されている。
【００１７】
前記被覆部材１６は、エンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されており、内部にバッテリー収納空間が形成されるとともに、上端部に前記燃料タンクに用いられる燃料タンク用蓋体と同等の形状に形成された蓋体１８が着脱自在に取付けられている。この蓋体１８は、被覆部材１６に形成された開口部（図示せず）を開閉するように構成されている。また、この蓋体１８と被覆部材１６との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等のシール構造が採られており、水が被覆部材１６内に浸入することがないように構成されている。
【００１８】
この実施の形態による被覆部材１６は、内部に第１のバッテリー１９が収納され、前記蓋体１８が取外された状態で上方に露出する部分に充電用コネクタ２０が取付けられている。なお、被覆部材１６は、この実施の形態では収納部材として機能するように形成されているが、下方が略全域にわたって開放されるカバー状や、下方の一部が開放されるような形状に形成することもできる。
前記バッテリボックス１７は、第２のバッテリー２１が収納されている。この第２のバッテリー２１と前記第１のバッテリー１９は、動力ユニット８のモータ１３に給電するためのものである。なお、この実施の形態では第１、第２のバッテリー１９，２１を装備する例を示したが、車体に搭載するバッテリーとしては、これらのうち何れか一方のみとすることができる。
【００１９】
動力ユニット８は、車体前側の端部に位置する前記モータ１３と、このモータ１３の後端部に取付けられたシャフトドライブ式伝動装置３１と、このシャフトドライブ式伝動装置３１とともに後輪３を支持する車体右側のアーム３２（図４参照）とによって構成され、前記モータ１３の前端部が前記車体フレーム６に上下方向に揺動自在に連結されるとともに、後輪３を支持する後端部がリヤクッションユニット３３を介して車体フレーム６の後部に連結されている。
【００２０】
前記モータ１３の前端部と車体フレーム６との連結部分は、モータ１３のハウジング３４に上方へ延びるように取付けられた左右一対の連結用ブラケット３５と、前記メインパイプ９の後端部に下方へ延びるように溶接された左右一対の支持用ブラケット３６と、これらのブラケット３５，３６の突出側端部どうしを互いに回動自在に連結する水平な支軸３７とによって構成されている。
【００２１】
前記モータ１３は、図４に示すように、車幅方向の中央部に軸線Ｃ１が車体の前後方向を指向する状態で設けられている。この実施の形態によるモータ１３は、軸線Ｃ１が車体の車幅方向の中心線Ｃ２に対して車体左側に偏るように位置付けられている。図４において、４１はモータ１３のロータ、４２は出力軸を示す。このモータ１３は、操向ハンドル５に設けられたスロットルグリップ４３（図２参照）の操作量に対応するように出力が制御される。この出力の制御は、図１に示すように、動力ユニット８の前方に設けられたコントローラ４４が実施する。
【００２２】
また、この実施の形態による電動二輪車１においては、前記スロットルグリップ４３の近傍に設けられた出力切換スイッチ（図示せず）によって乗員の年齢、技量などに応じてモータ１３の出力を調整できるように構成されている。
前記このコントローラ４４は、前輪２とモータ１３との間であって、エンジン駆動式自動二輪車においてラジエータが搭載されている位置に配設されている。さらに、このコントローラ４４は、図１に示す側面視において、前記ラジエータと同等の形状に形成されている。
【００２３】
前記シャフトドライブ式伝動装置３１は、図４に示すように、前記モータ１３の後端部に図示していない固定用ボルトによって固定された前端部の減速機４５と、後輪３を回転自在に支持する後部駆動装置４６と、前記減速機４５と前記後部駆動装置４６とを接続する伝動アーム４７とによって構成されている。
【００２４】
前記減速機４５は、モータ１３のハウジング３４に固定されたハウジング４８と、これらのハウジング３４，４８の内部に収容された減速用歯車４９，５０などによって構成されている。この減速機４５のハウジング４８は、前記モータ１３のハウジング３４の後端部の全域を後方から覆い、内部に歯車室５１が形成されるように構成されている。詳述すると、減速機４５のハウジング４８は、モータ１３のハウジング３４の後面に車幅方向と上下方向の略全域にわたって結合されるように形成されている。この実施の形態では、前記ハウジング４８がモータ１３のハウジング３４に直接接続される例を示したが、本発明はこのような限定にとらわれることはなく、前記ハウジング４８とモータ１３のハウジング３４との間にガスケット（図示せず）などのシール部材を介装することもできる。
【００２５】
これらのハウジング３４，４８の内部に設けられた減速用歯車４９，５０のうち一方の入力歯車４９は、モータ１３の出力軸４２に固着され、この入力歯車４９に噛合する他方の出力歯車５０は、前記出力軸４２より車体左側に位置付けられて前端部がモータ１３のハウジング３４に回転自在に支持され、後端部が減速機４５のハウジング４８に回転自在に支持されている。また、これらの減速用歯車４９，５０は、軸線が同一の水平面上に位置するように位置付けられている。
【００２６】
前記後部駆動装置４６は、エンジン駆動式自動二輪車に用いられているシャフトドライブ式伝動装置の後部駆動装置と同等の構造が採られており、ハウジング５２によって後輪３の車軸５３の車体左側の端部を回転自在に支持し、前記車軸５３の車体左側の端部に減速用傘歯車５４，５５を介して接続された従動軸５６を備えている。後輪３の車軸５３の車体右側の端部は、前記アーム３２の後端部に回転自在に支持されている。また、後部駆動装置４６の前記従動軸５６は、後述する伝動アーム４７の伝動軸５７を介して前記減速機４５の出力歯車５０に接続されている。
【００２７】
前記伝動アーム４７は、ロッドからなる前記伝動軸５７と、後輪３の側方で前後方向に延びて前記伝動軸５７を収容する取付け用フランジ付きの断面円形のパイプ５８とによって構成され、前端部が固定用ボルト５９によって前記減速機４５のハウジング４８に固定され、後端部が固定用ボルト６０によって前記後部駆動装置４６のハウジング５２に固定されている。前記伝動軸５７は、両端部が前記出力歯車５０と従動軸５６とに剛直に結合され、出力歯車５０の回転を従動軸５６に伝達する。
まとめ
【００２８】
上述したように構成された電動二輪車１は、モータ１３の出力軸４２の回転が減速機４５から伝動軸５７と後部駆動装置４６とを介して後輪３の車軸５３に伝達され、このように後輪３が駆動されることによって走行する。また、この電動二輪車１は、例えば路上の凹凸を越えたりしたときに動力ユニット８が支軸３７を中心にして上下方向に揺動する。
【００２９】
このように電動二輪車１が走行するときに乗員は、両脚で被覆部材１６を挾んでニーグリップを行うことによって、上体を安定させることができる。前記被覆部材１６は、エンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されているから、乗員は、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。
【００３０】
また、前記被覆部材１６と蓋体１８との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等の防水構造を採ることができるから、水に濡れてはならないバッテリー１９や充電用コネクタ２０が収納されている被覆部材１６内に雨水などが浸入するのを確実に阻止することができる。
さらに、この実施の形態による電動二輪車１は、走行時にコントローラ４４に走行風が当たり易くなるから、このコントローラ４４を走行風によって効率よく冷却することができる。
さらにまた、この実施の形態の電動二輪車１は、動力ユニット３１以外の外観部材がエンジン駆動式自動二輪車のものと同等の形状に形成されているから、これを見る者にエンジン式自動二輪車と同等の印象を与えることができる。
【００３１】
この実施の形態による電動二輪車１の被覆部材１６は、少なくとも両側面がエンジン駆動式自動二輪車の燃料タンクと同等の形状に形成されて乗員がそれをニーグリップできるように構成されていれば、その形状を適宜変更することができる。すなわち、被覆部材１６としては、燃料を蓄えられる容器を構成するように形成する必要なない。
また、被覆部材１６に設ける蓋体１８もその構成を適宜変更することができる。すなわち、この実施の形態で示したような開口部に螺合するキャップ状を呈するように蓋体１８を形成する他に、蓋体１８は、その前端部に設けられたヒンジ（図示せず）を中心にして被覆部材１６に開閉自在に支持される構造を採ることができる。
【００３２】
上述した実施の形態ではバッテリーを二箇所に設ける例を示したが、図５および図６に示すように、一箇所にバッテリーを搭載することができる。図５は電動二輪車の他の例を示す側面図、図６は同じく平面図である。これらの図において、前記図１〜図４によって説明したものと同一もしくは同等の部材については、同一符号を付し詳細な説明を適宜省略する。
【００３３】
図５および図６に示す電動二輪車１は、被覆部材１６とシート１５との下方にバッテリボックス６１が設けられている。このバッテリボックス６１は、上方に向けて開放する箱状であって、前記被覆部材１６の後部内からシート１５の着座部分の下方まで前後方向に延びるように形成されており、内部にバッテリー６２が収納されている。
【００３４】
この実施の形態による被覆部材１６とシート１５は、一つの組立体として扱うことができるように一体的に形成され、車体フレーム６に図示していないブラケットを介して上下方向に着脱可能に取付けられている。また、この被覆部材１６とシート１５とからなる組立体は、車体に装着された状態で前記バッテリボックス６１内のバッテリー収納空間の蓋を構成するように形成されている。すなわち、この組立体を車体フレーム６に対して上方に取外すことによって、バッテリー６２が上方に向けて露出するから、バッテリー６２を充電時などで着脱する作業が容易になる。
【００３５】
また、上述した二つの実施の形態では、被覆部材１６内に充電用コネクタ２０を設ける例を示したが、被覆部材１６内に充電用ケーブル（図示せず）を収納し、この充電用ケーブルの先端に設けられたプラグ（図示せず）が被覆部材１６の開口から外部に導出されるように構成することもできる。
この構成を採る場合には、充電器（図示せず）を被覆部材１６内など車体側に装着して前記充電用ケーブルを介して充電器が商用電源に接続される構成を採ったり、車外に設けられた充電器から前記充電用ケーブルを介して充電電流がバッテリー側へ供給される構成を採ることができる。被覆部材１６内に充電用ケーブルを収納させる場合には、ケーブルの引出し操作と収納操作が簡単になるようにコードリール（図示せず）を用いることができる。また、充電用コネクタ２０を設ける位置は、被覆部材１６内に限定されることはなく、適宜変更することができる。
【００３６】
【発明の効果】
以上説明したように本発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができるから、燃料タンクが操向ハンドルとシートとの間に位置するエンジン駆動式自動二輪車が電動化された電動二輪車を提供することができる。また、被覆部材と蓋体との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等の防水構造を採ることができるから、水に濡れてはならない充電用コネクタが収納されている被覆部材内に雨水などが浸入するのを確実に阻止することができる。このため、エンジン駆動式自動二輪車の燃料タンクと同等の形状に被覆部材を形成しているにもかかわらず、被覆部材内を有効に使うことができる。
【００３７】
請求項２記載の発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。また、前記被覆部材と蓋体との接続部分は、エンジン駆動式自動二輪車の燃料タンクと同等の防水構造を採ることができるから、水に濡れてはならないバッテリーが収納される被覆部材内に雨水などが浸入するのを確実に阻止することができる。このため、エンジン駆動式自動二輪車の燃料タンクと同等の形状に被覆部材を形成しているにもかかわらず、被覆部材内を有効に使うことができる。
【００３８】
請求項３記載の発明によれば、容量が相対的に多いバッテリーを被覆部材とシートとの下方に収納することができる。このバッテリーは、前記被覆部材とシートとを車体フレームから取外すことによって上方に向けて露出するから、充電時などで簡単に着脱することができる。このため、ニーグリップが容易な被覆部材を装備しながら、大容量のバッテリーを充電作業が簡単になるように搭載することができる。
【００３９】
請求項４記載の発明によれば、被覆部材を乗員が両脚で挾むことによって、エンジン駆動式自動二輪車と同一の感覚でニーグリップを行うことができる。また、この発明に係る電動二輪車は、コントローラに走行風が当たり易くなるから、コントローラを走行風によって効率よく冷却することができる。加えて、この発明によれば、外観がエンジン駆動式自動二輪車と同等の電動二輪車を形成することができるから、興趣に富む電動二輪車を提供することができる。
