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等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 in muscle strength by assisting various actions such as walking, raising and lowering of 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等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, the wiring is connected by a coupling means such as a connector having a contact 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。
特開２００２−３０１１２４号公報 特開２００１−２６８８２３号公報 特許第３８６４０９４号公報 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.
JP 2002-301124 A JP 2001-268823 A 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、給電器の給電ヘッド基板に給電コイルを有する給電コアを取り付け、受電器の受電ヘッド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、給電ヘッド基板と受電ヘッド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上述したように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 the power feeding head substrate of the power feeder, a power receiving core having a power receiving coil is attached to the power receiving head substrate of the power receiver, and the power feeding coil, the power feeding core, the power receiving coil, and the power receiving core are coaxial. By connecting the power feeder and the power receiver so that they face each other, power can be supplied in a non-contact manner by electromagnetic induction, and a transmitter and a receiver are attached to the power feeding head substrate and the power receiving head substrate, respectively. Thus, the power feeder and the power receiver are coupled to enable power feeding as described above, 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長くなると、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 further, if the distance between the power supply coil and the core and the power supply circuit on the substrate becomes long, 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.

また、上述した従来の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や各種データのやり取りとして利用する場合は、例えば電気アクチュエータと制御部との間で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の引き回しが何等考慮されていないことから、配線の取扱性が悪いという問題がある。   In addition, when the above-described conventional contactless power transmission device is used as a power supply means or various data exchanges with the walking assist device, for example, a wiring for supplying power between the electric actuator and the control unit In addition, there is a problem that the handling of the wiring is poor because no consideration is given to the routing of the wiring for exchanging various data.

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、配線の取扱性を良好にした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 an object of the present invention to provide a non-contact type transmission means that can transmit and receive signals accurately between the two and improve the handleability of wiring.

上記課題を解決するため、本発明は次のような構成を採用する。   In order to solve the above problems, the present invention employs the following configuration.

As shown in FIGS. 1 and 2, the contactless data and power transmission devices 1 and 2 can be used for the walking assistance device 3.

最初に歩行補助装置について説明すると、この歩行補助装置は、利用者Ａの左右の脚における各膝関節部にあてがわれるリンク機構部３，４と、利用者Ａの所望の部位で検出する信号に応じてリンク機構部３，４を駆動する駆動部５，６と、充電池等の電源部７と、駆動部５，６等を制御する制御部８とを含んだ構成となっている。   First, the walking assistance device will be described. This walking assistance device detects the link mechanism portions 3 and 4 applied to the knee joint portions of the left and right legs of the user A and signals detected at a desired part of the user A. Accordingly, the drive units 5 and 6 that drive the link mechanism units 3 and 4, the power supply unit 7 such as a rechargeable battery, and the control unit 8 that controls the drive units 5 and 6 and the like are included.

なお、図１では右脚用のリンク機構部３及び駆動部５のみ示しているが、左脚にも同様な構造のリンク機構部４及び駆動部６が配置される。   In FIG. 1, only the link mechanism unit 3 and the drive unit 5 for the right leg are shown, but the link mechanism unit 4 and the drive unit 6 having the same structure are also arranged on the left leg.

電源部７と制御部８はそれぞれ別個のハウジングに収納され、利用者の腰に巻きつけたベルト９に、各ハウジングに取り付けられたフック等により吊り下げられる。制御部８のハウジング内には、図示しないがＣＰＵ、電源回路、給電回路、通信回路等が収納されている。   The power supply unit 7 and the control unit 8 are housed in separate housings, and are suspended from a belt 9 wound around the user's waist by hooks or the like attached to the respective housings. Although not shown, a CPU, a power supply circuit, a power feeding circuit, a communication circuit and the like are housed in the housing of the control unit 8.

駆動部５，６は、そのハウジング内に収納される図示しないアクチュエータであるＤＣモータを有する。図６に示すように、ハウジング５ａ内には、ＤＣモータのほか、受電回路１１ａ等が組み込まれた基板１１が設けられている。この駆動部５，６は利用者の左右の大腿にハウジング５ａごとベルト１２によって装着される。   The drive parts 5 and 6 have DC motors which are actuators (not shown) housed in the housings. As shown in FIG. 6, in the housing 5a, a substrate 11 in which a power receiving circuit 11a and the like are incorporated in addition to a DC motor is provided. The driving units 5 and 6 are attached to the left and right thighs of the user by the belt 12 together with the housing 5a.

リンク機構部３，４は、上記駆動部５，６の各ハウジング５ａに固定されて各ハウジング５ａから利用者の膝関節へと大腿に沿って延びる固定リンク１３と、上記駆動部５，６の各ハウジング５ａ内に収納された上記ＤＣモータによって低速回転する図示しない短リンクと、短リンクにピン結合された連接棒１４と、上記固定リンク１３の上記膝関節に対応した箇所で一端がピン結合され、他端が上記連接棒１４の先端にピン結合され、利用者の下腿に沿って延びる揺動リンク１５とを具備する。揺動リンク１５は、ベルト１６によって利用者Ａの下腿に固定される。   The link mechanisms 3 and 4 are fixed to the housings 5a of the drive units 5 and 6 and extend along the thighs from the housings 5a to the user's knee joints.

ＤＣモータが制御部８によって制御されつつ回転すると、短リンクを介して連接棒１４が往復移動し、揺動リンク１５が膝関節の箇所のピンを支点にして揺動する。これにより、利用者の下腿が膝関節を支点にして前後に回動することとなり、利用者の歩行が援助されることになる。   When the DC motor rotates while being controlled by the control unit 8, the connecting rod 14 reciprocates through the short link, and the swing link 15 swings around the pin at the knee joint. As a result, the user's lower leg rotates back and forth with the knee joint as a fulcrum, and the user's walking is assisted.

本実施形態に係る非接触型データ及び電力伝送装置１，２は、図１及び図２に示すように、歩行補助装置の駆動部５，６と制御部８との間に設けられる。また、非接触型データ及び電力伝送装置１，２は、利用者Ａの左右の脚に対応して左右一対設けられる。   The contactless data and power transmission devices 1 and 2 according to the present embodiment are provided between the drive units 5 and 6 and the control unit 8 of the walking assistance device, as shown in FIGS. 1 and 2. A pair of left and right contactless data and power transmission devices 1 and 2 are provided corresponding to the left and right legs of the user A.

左右の非接触型データ及び電力伝送装置１，２は、互いに同様な構造であるから、以下一方のもので代表して説明する。   Since the left and right contactless data and power transmission devices 1 and 2 have the same structure, the following description will be given by using only one of them.

非接触型データ及び電力伝送装置１は、図３及び図４に示すように、給電器１ａと受電器１ｂとの組み合わせからなり、分離と連結を自在に行うことができるようになっている。図５及び図６に示すように、受電器１ｂが上記歩行補助装置における駆動部５のハウジング５ａに図示しないビスやネジ等の固定具によって固定されている。   As shown in FIGS. 3 and 4, the non-contact type data and power transmission device 1 is composed of a combination of a power feeder 1 a and a power receiver 1 b, and can be freely separated and connected. As shown in FIGS. 5 and 6, the power receiver 1 b is fixed to the housing 5 a of the drive unit 5 in the walking assist device by a fixing tool such as a screw or a screw (not shown).

すなわち、図６に示すようにハウジング５ａには、受電器１ｂと基板１１とを接続するケーブル３９が挿入されるケーブル挿入孔５０と、受電器１ｂに形成されたネジ孔５１に取り付けられる図示しないネジが挿入されるネジ挿入孔とが形成されている。このケーブル挿入孔と受電器１ｂから突出している突出部とを位置あわせした状態で、図示しないネジがハウジング５ａの内部から受電器１ｂのネジ孔５１に取り付けられてこの受電器１ｂがハウジング５ａ上に取り付けられるようになっている。また、受電器１ｂの底面には、シール部材としてのＯリング５２が装着される。これにより受電器１ｂをハウジング５ａに気密に取り付けることが可能となる。   That is, as shown in FIG. 6, the housing 5a is attached to a cable insertion hole 50 into which the cable 39 for connecting the power receiver 1b and the substrate 11 is inserted, and a screw hole 51 formed in the power receiver 1b (not shown). A screw insertion hole into which a screw is inserted is formed. In a state where the cable insertion hole and the protruding portion protruding from the power receiver 1b are aligned, a screw (not shown) is attached from the inside of the housing 5a to the screw hole 51 of the power receiver 1b so that the power receiver 1b is mounted on the housing 5a. Can be attached to. An O-ring 52 as a seal member is attached to the bottom surface of the power receiver 1b. Accordingly, the power receiver 1b can be attached to the housing 5a in an airtight manner.

このＯリング５２は、ケーブル挿入孔５０及びネジ孔５１の外側に設けられるため、受電器１ｂをハウジング５ａに取り付けた状態において、受電器１ｂとハウジング５ａとが接触している部分からケーブル挿入孔５０及びネジ孔５１を介してハウジング５ａの内部に外部から水等が浸入するのを完全に遮断することが可能となっている。   Since this O-ring 52 is provided outside the cable insertion hole 50 and the screw hole 51, the cable insertion hole starts from the portion where the power receiver 1 b and the housing 5 a are in contact with each other when the power receiver 1 b is attached to the housing 5 a. It is possible to completely block water and the like from entering the inside of the housing 5a through the screw holes 51 and the screw holes 51.

このように構成された歩行補助装置は、コネクタ等外部に露出した接点を用いる必要性がなくなるとともに、容易に着脱可能であって、防水処理が施されているため、例えば、脚当てをそのまま洗っても、従来のように当該接点に腐食や錆等が発生し、電力の供給が減少、及びリーク等の発生を防止できるので、不具合を生じないようにすることが可能となる。   The walking assist device configured as described above eliminates the need to use contacts exposed to the outside such as connectors, and is easily detachable and waterproofed. For example, the leg rest is washed as it is. However, since corrosion, rust, and the like are generated at the contact as in the prior art, the supply of power is reduced, and the occurrence of leakage and the like can be prevented, so that it is possible to prevent problems.

給電器１ａは、図７、図８、図９及び図１０に示すようなケーシングを有する。このケーシングは、板部１０と、板部１０の一端に配置される鍔部１７とを有し、樹脂等の非導電材で成形される。図３及び図４に示すように、板部１０は受電器１ｂのケーシングに形成された同じ形状の空洞１８内に合致可能であり、鍔部１７は受電器１ｂのケーシングの一端面に合致可能である。   The electric power feeder 1a has a casing as shown in FIG.7, FIG.8, FIG.9 and FIG. This casing has a plate portion 10 and a flange portion 17 disposed at one end of the plate portion 10 and is formed of a non-conductive material such as a resin. As shown in FIGS. 3 and 4, the plate portion 10 can be fitted into a cavity 18 having the same shape formed in the casing of the power receiver 1 b, and the flange portion 17 can be fitted to one end surface of the casing of the power receiver 1 b.

図７、図８、図９及び図１０に示すように、給電器１ａのケーシングには、凹陥部１９が形成され、この凹陥部１９内に給電ヘッド基板２０が収納され、この給電ヘッド基板２０に、非接触の電磁誘導作用により給電する給電コイル２１を有する給電コア２２と、非接触にて送受信する送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄとが取り付けられる。   As shown in FIGS. 7, 8, 9, and 10, a recess 19 is formed in the casing of the power feeder 1 a, and a power supply head substrate 20 is accommodated in the recess 19. In addition, a power supply core 22 having a power supply coil 21 that supplies power by non-contact electromagnetic induction action, and a transmitter 23a and receivers 23b, 23c, and 23d that transmit and receive without contact are attached.

凹陥部１９はケーシングの板部１０の広い方形面に形成され、その底は方形面に平行な平坦面１９ａとして形成される。また、凹陥部１９の内周には給電ヘッド基板２０の輪郭に合致する壁が形成される。凹陥部１９と板部１０の上記方形面との境界には段差部１９ｂが形成される。この段差部１９ｂにカバー板２４が嵌め込まれ、接着剤等により接着される。カバー板２４はその表面がケーシングの板部１０の表面と同一面となるように板部１０に固定される。このカバー板２４によって、給電コイル２１、給電コア２２等が収納された凹陥部１９が密閉される。   The recessed portion 19 is formed on a wide rectangular surface of the casing plate portion 10, and its bottom is formed as a flat surface 19 a parallel to the rectangular surface. A wall that matches the contour of the power feeding head substrate 20 is formed on the inner periphery of the recessed portion 19. A step portion 19b is formed at the boundary between the recessed portion 19 and the rectangular surface of the plate portion 10. The cover plate 24 is fitted into the stepped portion 19b and bonded with an adhesive or the like. The cover plate 24 is fixed to the plate portion 10 so that the surface thereof is flush with the surface of the plate portion 10 of the casing. The cover plate 24 seals the recessed portion 19 in which the power feeding coil 21, the power feeding core 22, and the like are housed.

このカバー板２４は、可視光を遮断して赤外線等所定の波長光のみを透過し、磁力を透過し、また、耐熱性を有する材料で形成される。   The cover plate 24 is made of a material that blocks visible light and transmits only light having a predetermined wavelength such as infrared rays, transmits magnetic force, and has heat resistance.

給電ヘッド基板２０は、その表面が凹陥部１９の開口側に向き、裏面が凹陥部１９の底側に向くように凹陥部１９内に収納され、その裏面が凹陥部１９の底の平坦面１９ａに当てられる。これにより、給電ヘッド基板２０は簡易かつ正確にケーシング内に取り付けられる。   The feeding head substrate 20 is housed in the recessed portion 19 so that the front surface faces the opening side of the recessed portion 19 and the back surface faces the bottom side of the recessed portion 19, and the back surface is a flat surface 19 a at the bottom of the recessed portion 19. To. Thereby, the electric power feeding head board | substrate 20 is attached in a casing simply and correctly.

上記給電コイル２１と給電コア２２は、この給電ヘッド基板２０における上記凹陥部１９の開口側に向いた表面２０ａに取り付けられ、図６に示すように、上記カバー板２４を介して受電器１ｂに対峙可能となる。   The feeding coil 21 and the feeding core 22 are attached to the surface 20a facing the opening side of the recessed portion 19 in the feeding head substrate 20, and are connected to the power receiver 1b via the cover plate 24 as shown in FIG. It becomes possible to confront.

給電コイル２１は環状に巻かれ、この給電コイル２１がフェライト等の磁性体からなる給電コア２２に装着される。   The feeding coil 21 is wound in an annular shape, and the feeding coil 21 is attached to a feeding core 22 made of a magnetic material such as ferrite.

また、上記送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄは、上記絶縁体である給電ヘッド基板２０の裏面２０ｂに取り付けられると共に、上記凹陥部１９の底の平坦面１９ａに形成された第１の凹部１９ｃ内に挿入される。このため、給電ヘッド基板２０は凹陥部１９の底に安定的に固定される。また、給電ヘッド基板２０には送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄに対応して通信用の赤外線等を通すための貫通孔２０ｃが形成される。この送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄは、例えば、ＩＲ−フォトトランジスタ、ＩＲ−ＬＥＤであり、所定の波長による通信（赤外線通信等）によって、後述する受電器１ｂ側の送受信部との間で所定の各種情報を送受信可能である。   The transmitter 23a and the receivers 23b, 23c, and 23d are attached to the back surface 20b of the feeding head substrate 20 that is the insulator, and are formed on the flat surface 19a at the bottom of the recessed portion 19. It is inserted into the recess 19c. For this reason, the power feeding head substrate 20 is stably fixed to the bottom of the recessed portion 19. In addition, a through-hole 20c is formed in the power supply head substrate 20 so as to pass infrared rays for communication and the like corresponding to the transmission unit 23a and the reception units 23b, 23c, and 23d. The transmission unit 23a and the reception units 23b, 23c, and 23d are, for example, IR-phototransistors and IR-LEDs, and communicate with a transmission / reception unit on the power receiver 1b side described later by communication (infrared communication or the like) using a predetermined wavelength. Various kinds of predetermined information can be transmitted and received between them.

上記給電コイル２１の端子２５も給電コイル２１等と同様に給電ヘッド基板２０の表面２０ａに形成される。また、上記送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄの各端子２６は、送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄと同様に給電ヘッド基板２０の裏面２０ｂに取り付けられると共に、凹陥部１９の底の平坦面１９ａに形成された第２の凹部１９ｄ内に挿入される。   The terminal 25 of the feeding coil 21 is also formed on the surface 20a of the feeding head substrate 20 in the same manner as the feeding coil 21 and the like. Further, the terminals 26 of the transmission unit 23a and the reception units 23b, 23c, and 23d are attached to the back surface 20b of the power feeding head substrate 20 in the same manner as the transmission unit 23a and the reception units 23b, 23c, and 23d.

A step portion 31b is formed at the boundary between the recessed portion 31 and the flat surface 18a. A cover plate 36 is fitted into the stepped portion 31b and bonded by an adhesive or the like. The cover plate 36 is fixed to the casing so that the surface thereof is flush with the flat surface 18a. The cover plate 36 seals the recessed portion 31 in which the power receiving coil 33, the power receiving core 34, and the like are accommodated. The cover plate 36 is formed of a material that transmits infrared light and transmits magnetic force.

受電ヘッド基板３２は、その表面３２ａが凹陥部３１の開口側に向き、裏面３２ｂが凹陥部３１の底側に向くように凹陥部３１内に収納され、その裏面３２ｂが凹陥部３１の底の平坦面３１ａに当てられる。これにより、受電ヘッド基板３２はケーシング内の定位置に簡易かつ正確に取り付けられる。   The power receiving head substrate 32 is housed in the recessed portion 31 so that the front surface 32 a faces the opening side of the recessed portion 31 and the back surface 32 b faces the bottom side of the recessed portion 31, and the back surface 32 b is on the bottom of the recessed portion 31.

The cable 39 can be routed more easily, and the length of the cable 39 can be shortened.

さらに、本実施形態の受電器１ｂによれば、ケーブル３９の引出口５４を図１１の左右方向においてボールプランジャ４３の内側のデッドスペースを用いて配置されているので、受電器１ｂの左右方向の長さを短くすることができる。   Furthermore, according to the power receiver 1b of the present embodiment, since the outlet 54 of the cable 39 is arranged using the dead space inside the ball plunger 43 in the left-right direction of FIG. 11, the left-right direction of the power receiver 1b is arranged.

The latter block 41 also serves to fill a gap generated in the recessed portion 31 like the former block 40. 11, 12, and 14, reference numeral 42 denotes a sealing member made of urethane resin or the like that fills a portion from the terminals 37 and 38 to the end of the cable 39. The seal member 42 is indicated by hatching. The seal member 42 and the above-described O-ring 52 prevent air, water, and the like from entering the casing from the connection portion of the cable 39.

また、図５、図１１及び図１３中、符号４３は位置決め機構としての上記ボールプランジャを示す。このボールプランジャ４３のボール４３ａがケーシングの空洞１８内に突出するようにケーシングに埋設される。ボール４３ａは図示しないスプリング等により空洞１８側へ付勢される。一方、図７に示すように、給電器１ａのケーシングにはボール４３ａに対応して穴４４が形成される。これにより、図５及び図６に示す如く給電器１ａの板部１０が受電器１ｂの空洞１８内に入り切ると、ボール４３ａが穴４４に嵌り込み、給電器１ａが受電器１ｂから不意に抜け出ないように給電器１ａを受電器１ｂ内に拘束する。   5, 11, and 13, reference numeral 43 indicates the ball plunger as a positioning mechanism. A ball 43 a of the ball plunger 43 is embedded in the casing so as to protrude into the cavity 18 of the casing. The ball 43a is urged toward the cavity 18 by a spring or the like (not shown). On the other hand, as shown in FIG. 7, a hole 44 is formed in the casing of the power feeder 1a corresponding to the ball 43a. Accordingly, as shown in FIGS. 5 and 6, when the plate portion 10 of the power feeder 1a completely enters the cavity 18 of the power receiver 1b, the ball 43a fits into the hole 44, and the power feeder 1a unexpectedly moves from the power receiver 1b. The power feeder 1a is restrained in the power receiver 1b so as not to come out.

次に、上記構成の非接触型データ及び電力伝送装置の作用について説明する。   Next, the operation of the non-contact type data and power transmission device having the above configuration will be described.

また、給電器１ａ及び受電器１ｂの双方の送受信部２３ａ，２３ｂ，２３ｃ，２３ｄ，３５ａ，３５ｂ，３５ｃ，３５ｄも互いに近接し、かつ同軸上で平行に対向する。これにより、双方の送受信部２３ａ，２３ｂ，２３ｃ，２３ｄ，３５ａ，３５ｂ，３５ｃ，３５ｄ間で所定の各種の情報が送受信可能となる。   Further, the transmission / reception units 23a, 23b, 23c, 23d, 35a, 35b, 35c, and 35d of both the power feeder 1a and the power receiver 1b are also close to each other and face each other on the same axis in parallel. As a result, various kinds of predetermined information can be transmitted / received between the transmission / reception units 23a, 23b, 23c, 23d, 35a, 35b, 35c, and 35d.

この連結操作は利用者Ａの左右の歩行補助装置に対してそれぞれ行われる。   This connection operation is performed on the left and right walking assist devices of the user A, respectively.

給電時には、制御部８を介して電源部７から給電器１ａ，２ａに電力が供給され、給電コイル２１に電圧が印加されることによって、給電コイル２１と受電コイル３３との間に電磁誘導回路が形成され、受電コイル３３が電磁誘導作用により誘電起電力を発生し、受電器１ｂ，２ｂが給電器１ａ，２ａから非接触で電力を受電する。各受電器１ｂ，２ｂで受電した電力は制御部８を介して歩行補助装置の左右の駆動部５，６の各ＤＣモータにそれぞれ供給される。   At the time of power feeding, power is supplied from the power supply unit 7 to the power feeders 1 a and 2 a via the control unit 8, and a voltage is applied to the power feeding coil 21, whereby an electromagnetic induction circuit is provided between the power feeding coil 21 and the power receiving coil 33.

The electric power received by each of the power receivers 1b and 2b is supplied to the DC motors of the left and right drive units 5 and 6 of the walking assistance device via the control unit 8, respectively.

また、給電器１ａと受電器１ｂとの送受信部２３ａ，２３ｂ，２３ｃ，２３ｄ，３５ａ，３５ｂ，３５ｃ，３５ｄ間で信号のやり取りが行われる。この信号は例えば負荷検出信号、モータ制御信号、センサ検出信号である。   In addition, signals are exchanged between the transmission / reception units 23a, 23b, 23c, 23d, 35a, 35b, 35c, and 35d between the power feeder 1a and the power receiver 1b. This signal is, for example, a load detection signal, a motor control signal, or a sensor detection signal.

制御部８は、主として演算機能を有するＣＰＵ（Central Processing Unit）、作業用ＲＡＭ、各種データやプログラムを記憶するＲＯＭ等を備える。上記ＣＰＵが、上記各種信号を処理し、ＲＯＭに記憶された各種プログラムを実行することにより、各部を制御するとともに、歩行補助装置の全体を統括制御する。   The control unit 8 includes a CPU (Central Processing Unit) mainly having a calculation function, a working RAM, a ROM for storing various data and programs, and the like. The CPU processes the various signals and executes the various programs stored in the ROM, thereby controlling each unit and overall controlling the walking assist device.

具体的には、制御部８は、図２に示すように、例えば、駆動部５，６のＤＣモータの回転方向や速度等ＤＣモータを駆動制御するための駆動信号Ｓｈを給電器１ａに出力する。また、制御部８は、給電する電力を制御するための電力制御信号Ｓｂを給電部１ａに出力する。   Specifically, as shown in FIG. 2, the control unit 8 outputs, for example, a drive signal Sh for driving and controlling the DC motor such as the rotation direction and speed of the DC motors of the drive units 5 and 6 to the power feeder 1 a. To do. Moreover, the control part 8 outputs the electric power control signal Sb for controlling the electric power supplied to the electric power feeding part 1a.

Recesses 19c and 31c are formed at the bottom of each casing made of non-conductive material 1b, and signal transmission / reception parts 23a, 23b, 23c, 23d, 35a, 35b, 35c and 35d are inserted into the recesses 19c and 31c. Therefore, even when the power transmission is large power of, for example, 10 W or more, interference with the signal system by the power supply system is prevented. Therefore, transmission / reception of signals between the power receiver 1b side and the power feeder 1a side is accurately performed. For example, the load state is detected on the power receiver 1b side, and the detection signal is accurately fed back to the power feeder 1a side. By doing so, loss of power transmission is prevented appropriately.

また、給電器１ａには、第２の凹部１９ｄが給電コア２２の端子２５、送信部２３ａ及び受信部２３ｂ，２３ｃ，２３ｄの各端子２６に接続されるリード線２５ａ，２６ａのケーブル２７の引出口５３まで連続して形成されているので、リード線２５ａ，２６ａの引き回しが容易になり、配線の取扱性を格段に向上させることができる。   Further, in the power feeder 1a, the second recess 19d has a lead 27a, 26a cable 27 connected to the terminal 25 of the power feeding core 22, the transmitter 23a, and the terminals 26 of the receivers 23b, 23c, 23d. Since it is continuously formed up to the outlet 53, the lead wires 25a and 26a can be easily routed, and the handling of the wiring can be remarkably improved.

さらに、受電器１ｂには、第２の凹部３１ｄが受電コア３４の端子３７、受信部３５ａ及び送信部３５ｂ，３５ｃ，３５ｄの各端子３８に接続されるリード線３７ａ，３８ａのケーブル３９の引出口５４まで連続して形成されているので、リード線３７ａ，３８ａの引き回しが容易になり、配線の取扱性を格段に向上させることができる。   Further, in the power receiver 1b, the second recess 31d has a lead wire 37a, 38a cable 39 connected to the terminal 37 of the power receiving core 34, the receiving unit 35a, and the transmitting unit 35b, 35c, 35d.
