特許文献１に提案された非接触充電する車両用共鳴型非接触充電（給電）システムでは、インフラストラクチャー（以下、インフラともいう。）側の１次側共鳴コイルと、電動車両側の２次側共鳴コイルとの間で、高周波大電力の送受を行うために、外来ノイズの発生が大きく、又給電制御が複雑になり易いという課題がある。   In a resonant non-contact charging (power feeding) system for a vehicle that performs non-contact charging proposed in Patent Document 1, a primary resonance coil on an infrastructure (hereinafter also referred to as infrastructure) side and a secondary side on an electric vehicle side Since high-frequency and high-power transmission / reception is performed with the resonance coil, there are problems that external noise is greatly generated and power supply control is likely to be complicated.

この課題を解決するために、電動車両に設けられた充電アームを、前記電動車両の走行中に、外部に設けられた給電装置に接触させ、前記給電装置から前記充電アームを通じて前記電動車両の蓄電装置を充電するように構成する接触充電システムが考えられる。   In order to solve this problem, a charging arm provided in an electric vehicle is brought into contact with an external power supply device while the electric vehicle is traveling, and the electric storage of the electric vehicle is transmitted from the power supply device through the charging arm. A contact charging system configured to charge the device is conceivable.

しかしながら、この接触充電システムでは、充電アームを通じて充電しながら走行している電動車両が、路面の状況あるいはアクセル・ブレーキ操作等により上下方向（ピッチング方向）に揺動すると、前記充電アームと前記給電装置との間の接触が不安定になり、接触が確保されない事態に至る可能性がある。   However, in this contact charging system, when the electric vehicle traveling while charging through the charging arm swings in the vertical direction (pitching direction) due to the road surface condition or the accelerator / brake operation, the charging arm and the power feeding device There is a possibility that the contact between the two becomes unstable and the contact is not secured.

この発明はこのような課題を考慮してなされたものであって、給電装置と電動車両とが前記電動車両の充電アームを介して接触充電しながらの走行中に、前記電動車両が、上下方向に揺動しても前記接触状態が確保されなくなることを抑制することを可能にする電動車両及び電動車両の接触充電システムを提供することを目的とする。 The present invention has been made in consideration of such a problem, and the electric vehicle is moved in the vertical direction while the power feeding device and the electric vehicle are in contact charging through the charging arm of the electric vehicle. and to provide a contact charging system of an electric vehicle both及 beauty electric vehicle that allows suppressing also swung said contact state is no longer reserved.

It is characterized by that.

この発明に係る電動車両の接触充電システムは、給電装置と、該給電装置から電力が供給される駆動用の蓄電装置を備える電動車両とから構成される前記電動車両の接触充電システムであって、前記給電装置は、前記電動車両の側部に対向するとともに前記電動車両の走行方向に沿って架線が固定された構成とされ、前記電動車両は、前記電動車両の前記側部に収納されるとともに、前記給電装置の対応する前記架線に対向するように設けられる受電部を有し、車幅方向に延出する充電アームを備えた構成とされ、給電時に、前記充電アームが前記車幅方向に延出され、前記給電装置の前記架線と前記充電アームの前記受電部とが接触されて、前記蓄電装置が充電される前記電動車両の接触充電システムであって、前記充電アームの前記受電部は、前記車幅方向に延出されるアーム部の先端に取り付けられており、前記充電アームの前記受電部は、前記アーム部に対して上側及び下側にそれぞれ取り付けられたスプリングからなる第１サスペンションを介して、前記アーム部に連結されていることを特徴とする。 The contact charging system for an electric vehicle according to the present invention is a contact charging system for an electric vehicle including a power feeding device and an electric vehicle including a power storage device for driving to which electric power is supplied from the power feeding device. The power feeding device is configured to face a side portion of the electric vehicle and have an overhead line fixed along a traveling direction of the electric vehicle. The electric vehicle is housed in the side portion of the electric vehicle. And a power receiving portion provided to face the corresponding overhead line of the power supply device, and a charging arm extending in the vehicle width direction, wherein the charging arm is arranged in the vehicle width direction during power supply.
