- the separation of the wiring from the electrical component can be suppressed.
- the detachment-restricting member is fixed to the stay on the opposite side to the part to which the electrical component is attached.
- the wiring support portion rises from the rear surface side to the component mounting surface side in the attachment / detachment direction. For this reason, the wiring support portion has a shape having a depth in the attachment / detachment direction, and supports the wiring with a margin in the attachment / detachment direction. This makes it harder for the wiring and the connector to come off from the wiring support section.
- the cover member for covering the connector by providing the cover member for covering the connector, it is possible to increase the waterproofness of the connection portion between the connector and the electrical component and to make the connector harder to come off.
- the electrical component is disposed at a position above the front wheel so as to be covered by the vehicle body front cover, so that the electrical component can be easily accessed from the front wheel side into the front cover.
- the connector can be prevented from coming off while being arranged.
- the electrical components can be firmly installed by fixing the stay to the vehicle body frame.
- the high-pressure side connection portion of the down-regulator is arranged inside the low-pressure side connection portion in the vehicle width direction. Therefore, disturbance from the outside in the vehicle width direction is less likely to be applied to the connection portion between the high voltage line connector and the high voltage side connection portion, and the protection of the down regulator can be enhanced.
- the detachment-restricting member avoids the low-voltage line when viewed from the attaching / detaching direction with respect to the stay. Therefore, for example, even when the electrical component is attached / detached while the low-voltage line is connected to the low-voltage side connection portion, interference between the low-voltage line and the separation restricting member is suppressed. For this reason, the degree of freedom in the work of attaching and detaching electrical components can be increased.

スイングユニット10は、前端部がリンク機構19を介して車体フレーム11に上下揺動可能に支持されるスイングアーム20と、スイングアーム20の後部左側で駆動軸31を左右方向に沿わせて配置される電気モータ30と、電気モータ30の後方に連なる減速機35と、を一体に有している。
図2に示すように、バッテリ100は、シート8の下方に搭載されている。バッテリ100は、平面視でシート8(特に前シート8a)と重なるように配置されている。バッテリ100は、複数(例えば前後二つ)の単位バッテリ101,102で構成されている。複数の単位バッテリ101,102は、互いに同一構成とされている。以下、各単位バッテリ101,102をそれぞれ前バッテリ101、後バッテリ102という。前後バッテリ101,102は、それぞれ断面矩形状(例えば略正方形状)をなして長手方向に延びる角柱状(直方体状)をなしている。前後バッテリ101,102は、それぞれ断面形状の前後辺を左右方向に沿わせ、かつ左右側辺を前後方向に沿わせて配置されている。前後バッテリ101,102は、それぞれ長手方向を上方に位置するほど後方に位置するように傾斜させた起立姿勢で配置されている。前後バッテリ101,102は、互いに平行に傾斜し、前後面間に一定間隔を空けて配置されている。
図4を併せて参照し、前後バッテリ101,102は、ジャンクションボックス(分配器)323およびコンタクタ(電磁開閉器)324を介して、PDU321に接続されている。PDU321からは三相ケーブル80が延び、この三相ケーブル80が電気モータ30に接続されている。
前後バッテリ101,102は、車体に対して着脱可能なモバイルバッテリである。前後バッテリ101,102は、それぞれ車外の充電器で充電したり、モバイルバッテリとして外部機器の電源として利用する等、単独で用いることが可能である。
前後バッテリ101,102は、互いに同一の左右方向位置に配置されている。前後バッテリ101,102は、それぞれ平面視で車体左右中心を左右に跨いで配置されている。例えば、前後バッテリ101,102は、左右中心を平面視で車体左右中心と一致させている。前後バッテリ101,102は、平面視で電気モータ30と左右方向位置をずらして(相互に離間して)配置されている。
図4に示すように、PDU(Power Driver Unit)321およびECU(Electric Control Unit)322は、一体の制御ユニットであるPCU320を構成している。
バッテリ100からの電力は、コンタクタ324を介して、モータドライバたるPDU321に供給される。バッテリ100からの電力は、PDU321にて直流から三相交流に変換された後、三相交流モータである電気モータ30に供給される。
図2に示すように、PCU320は、ジャンクションボックス323、コンタクタ324及びチャージャー325とともに、センタートンネルCTの内側に配置されている。PCU320、ジャンクションボックス323、コンタクタ324およびチャージャー325は、車両前後方向における前後輪3,4間の中央位置CP(図2参照)よりも前方に配置されている。前後輪3,4間の中央位置CPよりも後方には、バッテリ100が配置されている。これにより、車両前後方向における制御系部品の重量バランスが良好になる。PCU320をサスペンションのバネ上に配置することで、例えばPCU320を電気モータ30とともにリアサスペンションのバネ下に配置する場合に比べて、バネ下重量が軽減される。
図5に示すように、DC-DCコンバータ326は、前輪3の上方に配置されている。DC-DCコンバータ326は、車両体前部に設けられたフロントサイドカバー(車体前部カバー)303に覆われる位置に配置されている。DC-DCコンバータ326は、PCU320よりも上方に配置されている。
図6~図8に示すように、DC-DCコンバータ326は、ステー200を介して、車体フレーム11のヘッドパイプ12に固定されている。
基部201は、例えば鋼板からなり、部品平面視で略三角形状をなす板状に形成されている。基部201の一側面(表面)は、DC-DCコンバータ326が取り付けられる部品取り付け面201aとされている。部品取り付け面201aは、他側面(裏面)は、取り付けアーム202が取り付けられる裏面201bとされている。DC-DCコンバータ326は、部品取り付け面201aに対し、部品取り付け面201aと略直交する方向で接近離反することで、ステー200に対して着脱可能である。
図6~図8に示すように、DC-DCコンバータ326は、高圧側端子(高圧側接続部)326Pと、低圧側端子(低圧側接続部)326Nと、を備えている。高圧側端子326Pには、前記バッテリ100側(入力側)の高電圧線90が接続されている。低圧側端子326Nには、サブバッテリ327側(出力側)の低電圧線92が接続されている。
図6~図10に示すように、ステー200には、離脱規制部材210が一体的に設けられている。離脱規制部材210は、高電圧線90の高圧側コネクタ91が高圧側端子326Pから離脱することを規制する部材である。離脱規制部材210は、例えば細身の鋼材(線材)からなり、配線サポート部211と、固定アーム214と、を備えている。離脱規制部材210は、基部201の辺201p側から分岐するように設けられている。
一対の固定アーム214は、一対の延出部213の並び方向で、一対の延出部213よりも幅広に離間する一対の幅広部(アーム本体)215を備えている。一対の幅広部215は、ステー200側に位置するほど互いに離間するように傾斜し、あたかも台形状を描くように配置されている。一対の幅広部215の間は、高圧側コネクタ91を挿通可能な第二開口部215aとされている。
まず、DC-DCコンバータ326をステー200の基部201に締結固定するに先立ち、高電圧線90の高圧側コネクタ91をDC-DCコンバータ326の高圧側端子326Pに接続しておく。このとき、図11中に二点鎖線で示すように、離脱規制部材210の一対の幅広部215の間の第二開口部215aを通して、高圧側コネクタ91を前記着脱方向他側から着脱方向一側に向けて(図中下方から上方に向けて)に挿通する。
図12に示すように、離脱規制部材210は、前記着脱方向から見て、少なくとも基部201の外側において、低電圧線92および低圧側コネクタ93を避けて配置されている。低電圧線92の低圧側コネクタ93は、高圧側コネクタ91に比べて着脱の自由度が高い。低電圧線92の低圧側コネクタ93は、DC-DCコンバータ326の基部201への取り付け前または取り付け後の何れにおいても、低圧側端子326Nに着脱可能であることが望ましい。したがって、離脱規制部材210は、DC-DCコンバータ326の着脱方向から見て、少なくとも基部201の平面視の外側において、低電圧線92を避けて配置されている。
例えば、電装品として、ダウンレギュレータとして用いられるDC-DCコンバータ326を例示したが、これに限らない。本発明は、車両における他の電装品に適用してもよい。
例えば、配線サポート部は、U字状に限らず、全体的に湾曲したC字状や螺旋状でもよい。離脱規制部材は、一対の固定アームを持つものに限らず、単一の固定アームを持つものでもよい。
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、当該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。
