Description

本発明は、例えば歩行補助装置において非接触でデータ及び電力を伝送することができる給電器、受電器並びに非接触型データ及び電力伝送装置に関する。   The present invention relates to a power feeder, a power receiver, and a non-contact type data and power transmission device that can transmit data and power in a non-contact manner, for example, in a walking assistance device.

近年、筋力の衰えた老人や傷病者の、歩行動作、階段の昇降動作、着座姿勢からの起立動作、起立姿勢からの着座動作などの各種動作を補助することで、筋力の低下を補助するための歩行補助装置が提案されている（例えば、特許文献１参照）。   In order to assist the decline of muscle strength by assisting various actions such as walking, raising and lowering stairs, standing up from sitting posture, and sitting up from standing posture for elderly people and victims with weak muscle strength in recent years Has been proposed (for example, see Patent Document 1).

このような歩行補助装置は、人体の関節を曲げる電気アクチュエータ等を脚に取り付け、電気アクチュエータ等を制御するための制御部、電源電池等を人体の背や腰に取り付けるようになっている。このため、電気アクチュエータと制御部との間では、電力を供給するための配線や、各種データをやり取りするための配線が必要となる。通常、この種の装置は、外部に露出した接点を有するコネクタなどの結合手段によって配線間が接続される。   Such a walking assist device is configured to attach an electric actuator or the like for bending a joint of a human body to a leg, and attach a control unit for controlling the electric actuator or the like, a power supply battery, or the like to the back or waist of the human body. For this reason, wiring for supplying electric power and wiring for exchanging various data are required between the electric actuator and the control unit. Usually, in this type of device, wirings are connected by a coupling means such as a connector having contacts exposed to the outside.

一方、従来各種の非接触型電力伝送装置が提案されており（例えば、特許文献２，３参照）、このような非接触型電力伝送装置を上記歩行補助装置に電力の供給手段として利用することも可能である。   On the other hand, various non-contact power transmission devices have been proposed (see, for example, Patent Documents 2 and 3), and such a non-contact power transmission device is used as a power supply means for the walking assist device. Is also possible.

特開２００２−３０１１２４号公報JP 2002-301124 A 特開２００１−２６８８２３号公報JP 2001-268823 A 特許第３８６４０９４号公報Japanese Patent No. 3864094

本発明者は、非接触型電力伝送装置を歩行補助装置等において電力の伝送のみならずデータ信号の伝送にも利用することに思い至り、次のような非接触型電力伝送装置を案出した。   The present inventor came up with the idea of using the non-contact power transmission device not only for power transmission but also for data signal transmission in a walking assist device or the like, and devised the following non-contact power transmission device. .

すなわち、給電器の給電基板に給電コイルを有する給電コアを取り付け、受電器の受電基板に受電コイルを有する受電コアを取り付け、給電コイル及び給電コアと受電コイル及び受電コアとが同軸上で対向するように給電器と受電器とを結合することで、電磁誘導作用により非接触で給電することができるようにし、また、給電基板と受電基板とに送信部及び受信部をそれぞれ取り付けて、給電器と受電器とを結合して給電可能にすると同時に各種データのやり取りも非接触で行うことができるようにした。   That is, a power feeding core having a power feeding coil is attached to a power feeding board of a power feeder, a power receiving core having a power receiving coil is attached to a power receiving board of a power receiver, and the power feeding coil, the power feeding core, the power receiving coil, and the power receiving core are coaxially opposed to each other. By connecting the power feeder and the power receiver as described above, power can be supplied in a non-contact manner by electromagnetic induction, and a transmitter and a receiver are attached to the power supply board and the power reception board, respectively. And the power receiver can be combined to enable power supply, and at the same time, various data can be exchanged without contact.

しかしながら、電力とデータ信号とを同じ伝送装置で伝送する場合、給電電力が小さい場合は漏洩する電力が少なく干渉は少ないが、電源系の伝送電力が大体１０Ｗ以上になると、漏洩電力がデータを伝送するための信号系に干渉し始める。デジタル系はこの干渉に比較的耐え得るが、アナログ系は不安定になり、更に、基板上での給電コイル及びコアと給電回路との距離が大きくなると、データの伝送に支障が生じる。このため、例えば受電器内での受電部の負荷状態を検出し、受電器側から給電器側へ検出信号をフィードバックすることによって、電力伝送のロスを防ぐことが難しいものとなっていた。   However, when power and data signals are transmitted by the same transmission device, if the power supply power is small, the leakage power is small and there is little interference. However, if the transmission power of the power supply system is approximately 10 W or more, the leakage power transmits data. Begin to interfere with the signal system to do. The digital system can withstand this interference relatively, but the analog system becomes unstable, and if the distance between the power supply coil and the core and the power supply circuit on the substrate is increased, the transmission of data is hindered. For this reason, for example, it is difficult to prevent loss of power transmission by detecting the load state of the power receiving unit in the power receiver and feeding back the detection signal from the power receiver side to the power feeder side.

本発明は、上記課題を解決するためになされたものであり、電力伝送が例えば１０Ｗ以上の大電力となる場合においても電源系による信号系への干渉を防ぎ、受電器側と給電器側との間で信号を正確に送受信することができる非接触型の伝送手段を提供しようというものである。   The present invention has been made to solve the above-described problem. Even when the power transmission is large power of, for example, 10 W or more, the interference with the signal system by the power supply system is prevented. It is intended to provide a non-contact type transmission means capable of accurately transmitting and receiving signals between the two.
