Abstract
Description
本発明は、2019年9月27日に、日本に出願された特願2019-177752号に基づき優先権を主張し、その内容をここに援用する。
(1)本発明の態様に係る可搬型バッテリの充電器(1)は、電動車両に用いられる可搬型バッテリの充電器(1)であって、バッテリ(100)を載置するトレイ(2)を備え、前記トレイ(2)は、前記充電器(1)への載置状態における前記バッテリ(100)の長さ方向(V1)に沿うように形成される底面部(10)と、前記充電器(1)への載置状態における前記バッテリ(100)の高さ方向(V2)に沿うように前記底面部(10)から立ち上がり、前記バッテリ(100)の幅方向(V3)の側面に対向する側面部(12)と、を有し、前記底面部(10)及び前記側面部(12)の一部を上方から覆う上部カバー(3)を更に備える。
バッテリをトレイに載置する際、トレイの底面部及び側面部に沿ってバッテリを案内することができる。したがって、バッテリを充電器にスムーズに載置することができる。 加えて、底面部及び側面部の一部を上方から覆う上部カバーを更に備えることで、以下の効果を奏する。底面部及び側面部の他の一部は上方が開口するため、上方からバッテリを載置しやすい。
加えて、トレイの側面部は充電器への載置状態におけるバッテリの高さ方向に沿うように底面部から立ち上がることで、以下の効果を奏する。トレイの側面部の高さ方向の寸法を底面部の長さ方向の寸法よりも短尺にした場合には、上下方向に複数の充電器を配置しやすい。さらに、バッテリを高さ方向に短尺にした場合には、バッテリが充電器に装着された状態で上下方向に複数の配置をしやすい。
上部カバーに上方からバッテリが落下した場合であっても、充電器端子は上部カバー及びフレームで保護されるため、充電器端子へ衝撃が伝わることを好適に抑制することができる。
接続位置にある操作部に上方からバッテリの荷重がかかった場合であっても、操作部は上方からの荷重で軸回りの下方に回動し、退避位置に移動するため、載置している途中のバッテリが充電器端子に干渉することを抑制することができる。
バッテリを上下反転して載置しようとした場合には、バッテリが上部カバーに干渉するため、バッテリが充電器端子に干渉することを抑制することができる。
図1に示すように、バッテリ100は、直方体状をなしている。例えば、バッテリ100は、リチウムイオンバッテリである。
図2に示すように、バッテリ100は、幅方向V3に延びる上下一対の第一辺101及び第二辺102と、高さ方向V2(図12参照)に延びる左右一対の第三辺103及び第四辺104と、を有する。バッテリ100は、長さ方向V1に延びる側面121,122を有する(図12参照)。第一辺101は、第二辺102とは反対側(図2の上側)に向けて凸の曲線形状を有する。バッテリ100の側面のうち、第一辺101の側の側面121(バッテリ100の高さ方向V2の一面)は、第二辺102の側の側面122とは反対側に向けて凸の曲面形状を有する。
図1に示すように、充電器1は、バッテリ100を載置するトレイ2と、トレイ2の一部を上方から覆う上部カバー3と、バッテリ100の充電制御を行う制御装置4(図12参照)と、充電器1本体の骨格を構成する本体フレーム5(図11参照)と、充電器1の端子6(以下単に「充電器端子6」という。図4参照)と、充電器端子6を保持する保持部材7(図4参照)と、充電器端子6を移動させる操作機構8(図11参照)と、を備える。充電器1の底面は、床面と平行に(水平に)形成されている。
図3に示すように、トレイ2は、バッテリ100(図1参照)を載置可能かつ取り出し可能に上方及び前方に開口している。トレイ2は、充電器1への載置状態におけるバッテリ100の長さ方向V1に沿うように形成される底面部10と、バッテリ100の底部を受ける受け面部11と、バッテリ100の幅方向V3の側面に対向する左右一対の側面部12と、を備える。受け面部11及び左右一対の側面部12は、充電器1への載置状態におけるバッテリ100の高さ方向V2に沿うように底面部10から立ち上がっている(図12参照)。図中符号12hは、レバー60の移動(第一リンク61の第一支軸65の回りの回動)を制限する長孔を示す。
図3に示すように、上部カバー3は、充電器1の後部上部に設けられている。上部カバー3は、トレイ2の底面部10及び左右一対の側面部12の一部を上方から覆っている(図12参照)。図12に示すように、上部カバー3は、充電器端子6及び保持部材7を上方から覆っている。側面視で、上部カバー3の上縁は、後側に向かうに従って下方に位置するように傾斜している。図4の前面視で、上部カバー3の開口縁部3aは、バッテリ100の第一側面121(図2参照)に沿う曲面形状を有する。
図12に示すように、制御装置4は、トレイ2の第一傾斜面10aの下方に配置されている。図6の上面視で、制御装置4は、幅方向V3に延びる矩形状をなしている。制御装置4は、バッテリ100の充電制御を行う複数の制御基板を備える。例えば、制御基板は、バッテリ100の充電制御を行う制御回路を内側に向けて配置されていてもよい。例えば、制御基板の外面には、フィンまたはヒートシンクが設けられていてもよい。
図11に示すように、本体フレーム5は、充電器1の前部に位置する前部フレーム30と、充電器1の後部に位置する後部フレーム40と、を備える。
前部フレーム30は、上下方向から見て矩形枠状の枠体31(図6参照)と、上下方向に延びる左右一対の柱体32と、幅方向V3に延びるクロスパイプ33と、を備える。
図12に示すように、保持部材7は、充電器端子6をバッテリ100に接続する方向(図中矢印J1方向)に保持する。図6の上面視で、保持部材7は、前方に開放するU字状をなしている。保持部材7は、前後方向に延びる左右一対の側部アーム部50と、充電器端子6を支持する支持アーム部51と、を備える。左右一対の側部アーム部50及び支持アーム部51は、同一の部材で一体に形成されている。なお、左右一対の側部アーム部50及び支持アーム部51は、異なる部材で一体に形成されていてもよい。
図12に示すように、操作機構8は、充電器端子6をバッテリ端子106に接続する接続位置(以下単に「接続位置」ともいう。図12の実線参照)とバッテリ端子106から退避させる退避位置(以下単に「退避位置」ともいう。図12の二点鎖線参照)との間で移動可能とするレバー60(操作部)を備える。
図13は、接続位置にあるレバー60と上部カバー3との間にバッテリ100が挿入された場合の一例を示す。図13の例では、バッテリ100の第二側面122の一部が接続位置にあるレバー60の上端に接している。また、バッテリ100の底角部(バッテリ100の第二側面122と第二面112とがなす角部)がトレイ2の第一傾斜面10aのリブ10bに接している。また、バッテリ100の第一側面121の一部が上部カバー3の開口縁部3aに接している。上部カバー3の端部の位置は、接続位置にあるレバー60と上部カバー3との間にバッテリ100が挿入された場合に、充電器端子6がバッテリ100の第二面112と干渉しないように設定されている。図中符号G1は、バッテリ100の第二面112と充電器端子6との間の隙間を示す。
以上説明したように、上記実施形態の可搬型バッテリ100の充電器1は、電動車両に用いられる可搬型バッテリ100の充電器1であって、バッテリ100を載置するトレイ2を備え、トレイ2は、載置状態のバッテリ100の長さ方向V1に沿うように形成される底面部10と、載置状態のバッテリ100の高さ方向V2に沿うように底面部10から立ち上がり、バッテリ100の幅方向V3の側面に対向する側面部12と、を有し、底面部10及び側面部12の一部を上方から覆う上部カバー3を更に備える。
この構成によれば、バッテリ100をトレイ2に載置する際、トレイ2の底面部10及び側面部12に沿ってバッテリ100を案内することができる。したがって、バッテリ100を充電器1にスムーズに載置することができる。
加えて、底面部10及び側面部12の一部を上方から覆う上部カバー3を更に備えることで、以下の効果を奏する。底面部10及び側面部12の他の一部は上方が開口するため、上方からバッテリ100を載置しやすい。
加えて、トレイ2の側面部12は載置状態のバッテリ100の高さ方向V2に沿うように底面部10から立ち上がることで、以下の効果を奏する。トレイ2の側面部12の高さ方向の寸法を底面部10の長さ方向の寸法よりも短尺にした場合には、上下方向に複数の充電器1を配置しやすい。さらに、バッテリ100を高さ方向V2に短尺にした場合には、バッテリ100が充電器1に装着された状態で上下方向に複数の配置をしやすい。
上部カバー3に上方からバッテリ100が落下した場合であっても、充電器端子6は上部カバー3及び幅方向延在部42で保護されるため、充電器端子6へ衝撃が伝わることを好適に抑制することができる。
接続位置にあるレバー60に上方からバッテリ100の荷重がかかった場合であっても、レバー60は上方からの荷重で第一支軸65回りの下方に回動し、退避位置に移動するため、載置している途中のバッテリ100が充電器端子6に干渉することを抑制することができる。
接続位置にあるレバー60と上部カバー3との間にバッテリ100が挿入された場合に、バッテリ100の第二面112が充電器端子6に干渉することを抑制することができる。
バッテリ100を上下反転して載置しようとした場合には、バッテリ100が上部カバー3に干渉するため、バッテリ100が充電器端子6に干渉することを抑制することができる。
上記実施形態では、第一傾斜面10aが充電器1の底面に対して傾斜している例を挙げて説明したが、これに限らない。例えば、第一傾斜面10aは、充電器1の底面に対して平行であってもよい。例えば、充電器1の底面(例えば、充電器載置用のロッカー等の底面)が水平面に対して傾斜していて、充電器1の底面と第一傾斜面10aとが互いに平行であってもよい。第一傾斜面10aは、水平面に対して傾斜していればよい。すなわち、バッテリ100が上方に向けて傾斜して配置されていればよい。
例えば、充電器は、自動二輪車のモバイルバッテリの充電器に限らず、電動車両以外の電気機器の充電器に適用してもよい。
そして、上記実施形態における構成は本発明の一例であり、実施形態の構成要素を周知の構成要素に置き換える等、本発明の要旨を逸脱しない範囲で種々の変更が可能である。
