Description
本実施形態に係る非接触給電装置は、図1に示すように、給電コイル機構1、車両センサ2(移動体センサ)、姿勢制御部3及び給電制御部4によって構成されている。なお、これら構成要素のうち、給電コイル機構1、車両センサ2及び姿勢制御部3は、本実施形態における姿勢設定手段を構成している。
本非接触給電装置の車両センサ2は、例えば駐車スペースPにおける車両Mの進入口近傍の状態を常時あるいは一定周期で監視しており、この進入口近傍に車両Mが進入してきたことを検出すると、当該車両Mの進入を示す検知信号(車両検知信号)を姿勢制御部3に出力する。そして、姿勢制御部3は、車両センサ2から上記車両検知信号が入力されると、モータ1eに駆動信号を出力して給電コイル1aの一端面1fを垂直姿勢から水平姿勢に変化させる。
本実施形態に係る非接触給電装置は、図3に示すように、給電コイル機構1A及び給電制御部4Aによって構成されている。なお、これら構成要素のうち、給電コイル機構1Aは、本実施形態における姿勢設定手段を構成している。
電力ケーブルは、高周波の放射を低減するように互いに撚り合わせた被覆ツイスト電線に金属箔又は金属網で覆うケーブルであることが望ましい。
この給電コイル機構1Aでは、通常状態ではコイルバネ1jの付勢力によって給電コイル1aが垂直姿勢を維持するが、給電スペースPに車両Mが進入してくると、当該車両Mの後部(あるいは先端部)が当接部1hと当接することにより給電コイル1aの姿勢が垂直姿勢から水平姿勢に変化し、さらに当接部1hが車両Mの底部と当接し続けることにより水平姿勢を維持する。すなわち、この給電コイル機構1Aでは、給電スペースPへの車両Mの進入を自ら検出すると共に、車両Mの移動を給電コイル1aの姿勢を変化させるための動力として利用する。
(1)上記第1実施形態では、一対の回転軸1b,1bを一端面1fに直交する2対の平行面の一方の対の中心に設けたが、本発明はこれに限定されない。図5に示すように、一端面1fに直交する一方の対において各平行面の端部に設けてもよい。第2実施形態においても、同様に一対の回転軸1b,1bを一端面1fに直交する一方の対において各平行面の端部に設けてもよい。
