Description

技術分野
この発明は、玩具用の駆動装置に係り、水中でのみ動作可能なスクリュを駆動する駆動制御装置に関する。
背景技術
無線操縦装置は主に移動体をモデルとすることが多く、船舶をモデルとする場合にその駆動装置は、実際の船舶同様にスクリュを用いることが多い。ジェット水流型船舶やホバークラフト型船舶と比較して駆動部の構造が単純であるためスクリュを用いることが多い。
スクリュは、自動車と比較して駆動部が水中で回転し駆動力を発生するためにその末端が極めて鋭利な３枚羽から構成されることが多い。船舶型玩具において鋭利な羽からなるスクリュの存在には難点がある。すなわち、水中でスクリュが回転する場合は問題無いが、空中でスクリュが誤って回転する場合に指等を差し出すと接触することで怪我をする可能性がある。また、生体に接触しなくとも他の器物と接触することで他の器物およびスクリュの両者に損傷を与える可能性がある。また、ヨーロッパ安全規格においてスクリュが空中で回転する船舶玩具は認定されないという問題を有していた。
従って、本発明の目的は、水中でのみ動作するスクリュを駆動する駆動制御装置の提供にある。
発明の開示
前記の課題を解決するため、本発明に係る駆動制御装置は、船体の着水を検出する手段と、着水を検出した場合には駆動可能として着水を検出できない場合に駆動を不可能とする機能を有する。
また、船舶型玩具は、着水を検出した場合には駆動可能として着水を検出できない場合に駆動を不可能とする機能を有する駆動制御装置を有する。
駆動制御装置は、水検知端子と水検出回路と電動機駆動スイッチと電動機とを有する。
駆動制御装置は、空中線とフィルタと超再生受信機と制御回路と操舵駆動増幅器と操舵部とを有する。
無線操縦式船舶型玩具は、水検知端子と水検出回路と電動機駆動スイッチと電動機とからなる無線操縦用水センサを有する。
無線操縦式船舶型玩具は、空中線とフィルタと超再生受信機と制御回路と操舵駆動増幅器と操舵部とを有する。
発明を実施するための最良の形態
本発明のその他の詳細、利点および特徴については、添付図面を参照しながら以下に記す実施例によって明らかにされる。
図１に示すように、駆動制御装置は、外部の水と接触させる水検出端子２と、水と接触したことによる短絡電流の有無を検知する水検出回路４と、水検出回路４によって短絡と開放を選択する電動機駆動スイッチ６と、受信情報をもとに操舵信号と駆動信号を発生する制御ＩＣ８と、駆動信号を増幅する駆動モータ駆動増幅回路１６と、増幅した電流で回転するモータを備えてスクリュを回転させる駆動モータ部１８と、操舵信号を増幅する操舵駆動増幅器２０と、増幅した操舵信号に基づいて操舵板の方向を変更させる操舵部２２と、フィルタ１２より伝達された信号を検波して低周波増幅する超再生受信部１０と、空中線１４で受信したＡＭ波よりノイズを除去するフィルタ部１２と、ＡＭ波を受信する空中線１４と、電源を供給するバッテリ２４とから構成される。
空中線１４はフィルタ部１２と電気的に接続され、フィルタ部１２は、超再生受信部１０と電気的に接続され、超再生受信部１０は制御ＩＣ８と電気的に接続される。制御ＩＣ８はさらに操舵駆動増幅器２０と電動機駆動スイッチ６とをそれぞれ電気的に接続される。操舵駆動増幅器２０は、操舵部２２と電気的に接続される。電動機駆動スイッチ６は、駆動モータ駆動増幅回路１６と水検出回路４と電気的に接続される。駆動モータ駆動増幅回路１６は駆動モータ部１８と電気的に接続され、水検出回路４は水検出端子２と接続される。またこれらの装置は何れも電源としてバッテリ２４と接続される。
空中線１４は、電波を受信することができる導体であればいかなる形状であってもよいが、好適には導線から構成される。
フィルタ１２は受信する電磁波の周波数帯のみを通過させる電気的フィルタであれば、能動型フィルタ、受動型フィルタの何れであってもよいが、本実施例では２７ＭＨｚを通過させる受動フィルタで構成する。
超再生受信部１０はフィルタを通過した電磁波を検波して制御ＩＣ８に伝達するためのトーン信号を発生する機能を有する。
制御ＩＣ８は、発生したトーン信号から予め決定された信号パターンより操舵駆動増幅器２０と電動機駆動スイッチ６とへそれぞれ操舵信号と駆動信号とを送出する機能を有する。
操舵駆動増幅器２０は、操舵信号を受信すると操舵部２２に内蔵されるサーボモータを駆動するのに必要な電流へ増幅して操舵部２２へ伝達する機能を有する。
操舵部２２は、増幅された電流で駆動され、左右に舵を方向変更させる機能を有する。
電動機駆動スイッチ６は、制御ＩＣ８の生成する駆動信号を受信して駆動モータ駆動増幅回路１６へ伝達するか否かを切り替える機能を有する。水検出回路４が水センサより水の存在を検出して発生する水検出信号を電動機駆動スイッチ６が受信した際ににのみ駆動信号を駆動モータ駆動増幅回路１６へ伝達する。すなわち、水が存在しない状態で、スクリュが駆動モータ部１８により回転させられることがないようにするためである。電動機駆動スイッチ６は、水検出回路４から伝達されて水が存在する場合に、ＯＮとなり、水が存在しない場合にＯＦＦとなる。
水検出回路４は、常に水検出端子２の２端子間の電圧を検出し、２端子間電圧降下がある値以上となった場合に２端子間の抵抗値が水の存在により発生したとみなして水検出を行う機能を有する。
水検出端子２は、２箇所の導体から構成され、その設置位置としては例えば船舶型玩具の場合は、船底の何れの位置でもよい。また、電動機が船外機等の場合は、船外機の最下部であればいずれの場所でも良い。
駆動モータ駆動増幅回路１６は、電動機駆動スイッチ６を介して送出された駆動信号を増幅して駆動モータ部１８を駆動可能な駆動電流を発生させる機能を有する。駆動モータ駆動増幅回路１６は、電動機駆動スイッチ６を介しているため電動機駆動スイッチ６がＯＦＦ状態である場合は作動しない。すなわち、水センサが水を検出しない場合は作動しない。
駆動モータ部１８は、駆動モータ駆動増幅回路１６より得た駆動電流で駆動されスクリュを回転させ、本システムが設置される船舶型玩具を駆動させる機能を有する。さらに、水センサが水を検出しない場合は電動機駆動スイッチ６がＯＦＦであるため、駆動モータ部１８とスクリュは回転しない。
本構成とすることで水センサが水を検出しない限り、スクリュが回転しない構成となった。このため、船舶型玩具を進水させない状態でスクリュが回転して、誤って怪我やスクリュの破損等の問題が解決される。
本願発明の船舶型玩具は、無線操縦で制御するための送信機を必要とする。送信機は、電源スイッチと駆動ボリュームと操舵ボリュームとを有する。電源スイッチをＯＮすることで電波の送信が可能となり、駆動ボリュームを変化させることで駆動モータ部１８の回転数を変更させる信号を、船舶型玩具に搭載する駆動制御装置に送信する。操舵ボリュームを変化させることで操舵部２２を変化させて船舶型玩具の舵を制御して進行方向が変わる。
操舵ボリュームを変化させると、変化信号で変調したＡＭ波が駆動制御装置に送出される。送出された信号は、空中線１４で受信され、超再生受信部１０で検波して制御ＩＣ８へトーン信号が送出される。制御ＩＣ８は、トーン信号より操舵信号を生成して操舵駆動増幅器２０へ伝達して、操舵駆動増幅器２０は操舵信号を増幅して操舵部２２へ伝達する。
一方、駆動ボリュームを変化させると、変化信号で変調したＡＭ波が駆動制御装置に送出される。送出された信号は、空中線１４で受信され、超再生受信部１０で検波して制御ＩＣ８へトーン信号が送出される。制御ＩＣ８は、トーン信号より駆動信号を生成して電動機駆動スイッチ６へ伝達する。
この時、船体が進水して、水センサがＯＮ状態であれば、駆動信号は駆動モータ駆動増幅回路１６へ伝達されて、駆動モータ部１８が動作してスクリュが回転する。
また、船体が水から外に出た状態では、水センサがＯＦＦ状態であり、駆動信号は電動機駆動スイッチ６がＯＦＦであるため駆動モータ駆動増幅回路１６へは伝達されず駆動モータ部１８が動作せずスクリュも回転しない。
すなわち、非使用時にスクリュが回転して怪我や破損等を防止する安全ロック機能を、水センサがを用いることで達成可能となる。
以上本発明の基本的構成とその典型的な実施例について説明したが、本発明の範囲と趣旨から逸脱することなく当業者においては種々の設計変更をなし得ることが理解されよう。
【図面の簡単な説明】
図１は、本発明に係る駆動制御装置の実施例を示すブロックダイアグラムである。TECHNICAL FIELD The present invention relates to a drive device for a toy, and more particularly to a drive control device that drives a screw that can operate only in water.
2. Description of the Related Art In many cases, a radio control device is mainly modeled on a moving body, and when a ship is modeled, a screw is often used as a driving device, similarly to an actual ship. Screws are often used because the structure of the drive unit is simpler than that of jet watercraft and hovercraft ships.
The screw is often composed of three blades whose ends are extremely sharp because the drive unit rotates in water to generate a driving force as compared with an automobile. There is a drawback in the existence of a screw made of sharp wings in a ship-type toy. That is, there is no problem when the screw rotates underwater, but there is a possibility of injury due to contact when a finger or the like is put out when the screw rotates by mistake in the air. In addition, there is a possibility that both the other object and the screw may be damaged by coming into contact with the other object without contacting the living body. In addition, there is a problem that a ship toy in which a screw rotates in the air is not certified according to European safety standards.
Accordingly, an object of the present invention is to provide a drive control device that drives a screw that operates only underwater.
DISCLOSURE OF THE INVENTION In order to solve the above-mentioned problems, a drive control device according to the present invention includes a means for detecting water landing on a hull, and a drivable when water landing is detected and a drive when water landing cannot be detected. Has a function that makes it impossible.
Further, the ship-type toy has a drive control device having a function of enabling driving when water landing is detected and disabling driving when water landing is not detected.
The drive control device has a water detection terminal, a water detection circuit, a motor drive switch, and a motor.
The drive control device includes an antenna, a filter, a super regenerative receiver, a control circuit, a steering drive amplifier, and a steering unit.
The radio-controlled marine toy has a radio-controlled water sensor including a water detection terminal, a water detection circuit, a motor drive switch, and a motor.
The radio-controlled marine toy has an antenna, a filter, a super-regenerative receiver, a control circuit, a steering drive amplifier, and a steering unit.
BEST MODE FOR CARRYING OUT THE INVENTION Other details, advantages and features of the present invention will become apparent from the embodiments described below with reference to the accompanying drawings.
As shown in FIG. 1, the drive control device includes a water detection terminal 2 for contacting with external water, a water detection circuit 4 for detecting the presence or absence of a short-circuit current due to contact with water, and a short-circuit by the water detection circuit 4. A motor drive switch 6 for selecting opening, a control IC 8 for generating a steering signal and a drive signal based on received information, a drive motor drive amplifier circuit 16 for amplifying the drive signal, and a motor rotating with the amplified current A drive motor unit 18 for rotating the screw by means of a screw, a steering drive amplifier 20 for amplifying the steering signal, a steering unit 22 for changing the direction of the steering plate based on the amplified steering signal, and detecting a signal transmitted from the filter 12. A super-reproduction receiver 10 for performing low-frequency amplification, a filter unit 12 for removing noise from AM waves received by the antenna 14, an antenna 14 for receiving AM waves, and a power supply It consists of Teri 24.
The antenna 14 is electrically connected to the filter unit 12, and the filter unit 12 is electrically connected to the super-reproduction receiving unit 10, and the super-regeneration receiving unit 10 is electrically connected to the control IC 8. The control IC 8 is further electrically connected to the steering drive amplifier 20 and the motor drive switch 6, respectively. The steering drive amplifier 20 is electrically connected to the steering unit 22. The motor drive switch 6 is electrically connected to the drive motor drive amplification circuit 16 and the water detection circuit 4. The drive motor drive amplification circuit 16 is electrically connected to the drive motor unit 18, and the water detection circuit 4 is connected to the water detection terminal 2. Each of these devices is connected to a battery 24 as a power source.
The antenna 14 may have any shape as long as it is a conductor capable of receiving radio waves, but is preferably formed of a conductor.
The filter 12 may be an active filter or a passive filter as long as it is an electric filter that passes only the frequency band of the electromagnetic wave to be received. In this embodiment, the filter 12 is configured by a passive filter that passes 27 MHz.
The super-reproduction receiving unit 10 has a function of detecting the electromagnetic wave passing through the filter and generating a tone signal to be transmitted to the control IC 8.
The control IC 8 has a function of transmitting a steering signal and a drive signal to the steering drive amplifier 20 and the motor drive switch 6 based on a signal pattern determined in advance from the generated tone signal.
The steering drive amplifier 20 has a function of receiving a steering signal, amplifying the current to a current necessary for driving a servomotor built in the steering unit 22, and transmitting the current to the steering unit 22.
The steering section 22 is driven by the amplified current and has a function of changing the direction of the rudder left and right.
The motor drive switch 6 has a function of receiving or not transmitting a drive signal generated by the control IC 8 and transmitting the signal to the drive motor drive amplifier circuit 16. The drive signal is transmitted to the drive motor drive amplifier circuit 16 only when the motor drive switch 6 receives a water detection signal generated by the water detection circuit 4 detecting the presence of water from the water sensor. That is, the screw is prevented from being rotated by the drive motor unit 18 in a state where water does not exist. The motor drive switch 6 is turned on when water is transmitted from the water detection circuit 4 and turned off when no water is present.
The water detection circuit 4 always detects the voltage between the two terminals of the water detection terminal 2, and when the voltage drop between the two terminals exceeds a certain value, it is considered that the resistance value between the two terminals has been generated due to the presence of water. To detect water.
The water detection terminal 2 is composed of two conductors, and may be installed at any position on the bottom of the ship, for example, in the case of a ship-type toy. When the electric motor is an outboard motor or the like, any location may be used as long as it is the lowest part of the outboard motor.
The drive motor drive amplification circuit 16 has a function of amplifying the drive signal transmitted via the motor drive switch 6 and generating a drive current capable of driving the drive motor unit 18. The drive motor drive amplification circuit 16 does not operate when the motor drive switch 6 is in the OFF state because the drive motor drive amplifier circuit 16 is connected via the motor drive switch 6. That is, when the water sensor does not detect water, it does not operate.
The drive motor unit 18 is driven by the drive current obtained from the drive motor drive amplification circuit 16 to rotate the screw and to drive the marine toy on which the present system is installed. Furthermore, when the water sensor does not detect water, the motor drive switch 6 is OFF, so that the drive motor unit 18 and the screw do not rotate.
With this configuration, the screw does not rotate unless the water sensor detects water. For this reason, the screw rotates without launching the marine toy, thereby solving the problem of accidental injury or damage to the screw.
The marine toy of the present invention requires a transmitter for controlling by radio control. The transmitter has a power switch, a drive volume, and a steering volume. By turning on the power switch, radio waves can be transmitted, and a signal for changing the rotation speed of the drive motor unit 18 by changing the drive volume is transmitted to the drive control device mounted on the marine toy. By changing the steering volume, the steering unit 22 is changed to control the rudder of the marine toy, and the traveling direction changes.
When the steering volume is changed, an AM wave modulated by the change signal is sent to the drive control device. The transmitted signal is received by the antenna 14, detected by the super-reproduction receiving unit 10, and a tone signal is transmitted to the control IC 8. The control IC 8 generates a steering signal from the tone signal and transmits it to the steering drive amplifier 20. The steering drive amplifier 20 amplifies the steering signal and transmits it to the steering unit 22.
On the other hand, when the drive volume is changed, the AM wave modulated by the change signal is sent to the drive control device. The transmitted signal is received by the antenna 14, detected by the super-reproduction receiving unit 10, and a tone signal is transmitted to the control IC 8. The control IC 8 generates a drive signal from the tone signal and transmits it to the motor drive switch 6.
At this time, if the hull launches and the water sensor is in the ON state, the drive signal is transmitted to the drive motor drive amplification circuit 16, and the drive motor unit 18 operates to rotate the screw.
When the hull comes out of the water, the water sensor is in the OFF state, and the drive signal is not transmitted to the drive motor drive amplification circuit 16 because the motor drive switch 6 is OFF, and the drive motor unit 18 operates. No screw rotation.
That is, the safety lock function of preventing the screw from rotating and causing injury or breakage when not in use can be achieved by using the water sensor.
While the basic configuration of the present invention and its typical embodiments have been described above, it will be understood that those skilled in the art can make various design changes without departing from the scope and spirit of the present invention.
