図2を参照して、コード収納装置600は、コードリール610と、電動モータ620と、制御ユニット650とを備える。
Referring to FIG. 2, the cord storage device 600 includes a cord reel 610, an electric motor 620, and a control unit 650.
コードリール610には、円筒状の胴部が設けられ、その胴部に受電用コード250が巻き付けられる。そして、受電用コード250を用いて外部充電が行なわれるときには、コードリール610に巻き付けられた受電用コード250が引き出される。また、外部充電が行なわれないときには、コードリール610は、受電用コード250を巻き取って収納する。
The cord reel 610 is provided with a cylindrical trunk portion, and the power receiving cord 250 is wound around the trunk portion. When external charging is performed using the power receiving cord 250, the power receiving cord 250 wound around the cord reel 610 is pulled out. When the external charging is not performed, the cord reel 610 winds and stores the power receiving cord 250.
コードリール610の回転軸612には弾性装置660が取り付けられる。この弾性装置660は、たとえば図2のような渦巻状のバネにより構成され、コードリール610に対して受電用コード250が巻き取られる方向へ巻取トルクが加えられるように構成される。なお、図2に示した弾性装置660の形状は一例であり、上述のような巻取トルクを生じさせることができれば、たとえばらせん状のバネや、つるまきバネを用いる構成であってもよい。あるいは、弾性装置660は、所望の弾性力を生じるものであれば、バネ以外の構成であってもよく、たとえば弾性ゴムなどを用いることも可能である。
The elastic device 660 is attached to the rotating shaft 612 of the cord reel 610. The elastic device 660 is configured by a spiral spring as shown in FIG. 2, for example, and is configured such that a winding torque is applied to the cord reel 610 in a direction in which the power receiving cord 250 is wound. The shape of the elastic device 660 shown in FIG. 2 is an example, and a configuration using a spiral spring or a helical spring may be used as long as the above-described winding torque can be generated. Alternatively, the elastic device 660 may have a configuration other than a spring as long as it generates a desired elastic force, and for example, elastic rubber or the like can be used.
電動モータ620の回転軸には、ギヤ621が設けられる。ギヤ621はコードリール610の側面に設けられたギヤ611と係合可能に配置される。
A gear 621 is provided on the rotating shaft of the electric motor 620. The gear 621 is disposed so as to be engageable with a gear 611 provided on the side surface of the cord reel 610.
ギヤ621は、受電用コード250をコードリール610に巻き取る際に、電動モータ620により回転させられる。たとえば利用者がスイッチ等を押すと、電動モータ620により、受電用コード250を巻き取る方向にコードリール610が回転される。これにより、受電用コード250がコード収納装置600に収納される。
The gear 621 is rotated by the electric motor 620 when the power receiving cord 250 is wound around the cord reel 610. For example, when the user presses a switch or the like, the cord reel 610 is rotated by the electric motor 620 in the direction in which the power receiving cord 250 is wound. As a result, the power receiving cord 250 is stored in the cord storage device 600.
同様に、ギヤ621は、受電用コード250がコードリール610から引き出される際に、電動モータ620により回転させられる。利用者がコードリール610を引っ張ることにより、コードリール610が回転し始めると、電動モータ620により、受電用コード250が引き出される方向にコードリール610が回転される。
Similarly, the gear 621 is rotated by the electric motor 620 when the power receiving cord 250 is pulled out from the cord reel 610. When the user pulls the cord reel 610 and the cord reel 610 starts to rotate, the electric motor 620 rotates the cord reel 610 in the direction in which the power receiving cord 250 is pulled out.
コードリール610の回転速度は、速度センサ630により検出され、検出結果を表す信号が制御ユニット650に入力される。
The rotation speed of the cord reel 610 is detected by the speed sensor 630, and a signal representing the detection result is input to the control unit 650.
図3に示すように、電動モータ620は、コードリール610の回転速度に応じたトルクを、コードリール610の回転方向と同じ方向(受電用コード250が引き出される方向)に付与することによってコードリール610を回転させるように制御ユニット650により制御される。電動モータ620のトルクを変化させる方法については、周知の一般的な方法を利用すればよいため、ここではその詳細な説明は繰り返さない。
As shown in FIG. 3, the electric motor 620 applies a torque corresponding to the rotation speed of the cord reel 610 in the same direction as the rotation direction of the cord reel 610 (direction in which the power receiving cord 250 is pulled out). Control unit 650 controls 610 to rotate. As a method of changing the torque of electric motor 620, a well-known general method may be used. Therefore, detailed description thereof will not be repeated here.
電動モータ620は、コードリール610の回転速度が第1しきい値SH1より小さいと、コードリール610の回転速度が速いほど大きなトルクをコードリール610に付与するように制御される。
When the rotational speed of the cord reel 610 is smaller than the first threshold value SH1, the electric motor 620 is controlled to apply a larger torque to the cord reel 610 as the rotational speed of the cord reel 610 increases.
コードリール610の回転速度が十分高いと、電動モータ620によりアシストしなくても、利用者は受電用コード250を容易に引き出すことが可能である。したがって、電動モータ620は、コードリール610の回転速度が第1しきい値SH1以上であると、トルクを低減するように制御される。電動モータ620は、コードリール610の回転速度が第2しきい値SH2以上であり、第3しきい値SH3より小さいと、トルクを零にするように制御される。
When the rotational speed of the cord reel 610 is sufficiently high, the user can easily pull out the power receiving cord 250 without assisting the electric motor 620. Therefore, the electric motor 620 is controlled to reduce the torque when the rotational speed of the cord reel 610 is equal to or higher than the first threshold value SH1. The electric motor 620 is controlled to make the torque zero when the rotational speed of the cord reel 610 is equal to or higher than the second threshold value SH2 and smaller than the third threshold value SH3.
電動モータ620は、コードリール610の回転速度が第3しきい値SH3以上であると、コードリール610の回転方向とは反対の方向(受電用コード250を巻き取る方向)にトルクを付与し、発電するように制御される。コードリール610の回転速度が第3しきい値SH3以上である場合、コードリール610の回転速度が速いほどトルクの絶対値が大きくされる。すなわち、発電電力が増大される。
When the rotational speed of the cord reel 610 is equal to or higher than the third threshold value SH3, the electric motor 620 applies torque in a direction opposite to the rotational direction of the cord reel 610 (direction in which the power receiving cord 250 is wound) Controlled to generate electricity. When the rotation speed of the cord reel 610 is greater than or equal to the third threshold value SH3, the absolute value of the torque is increased as the rotation speed of the cord reel 610 increases. That is, the generated power is increased.
一方、コードリール610の回転速度が零まで減速すると、電動モータ620は、トルクが零になるように制御される。したがって、受電用コード250を引き出している間、または巻き取っている間において、障害物等に受電用コード250が引っかかり、移動が不可能になると、電動モータ620のトルクが零にされる。
On the other hand, when the rotation speed of the cord reel 610 is reduced to zero, the electric motor 620 is controlled so that the torque becomes zero. Therefore, while the power receiving cord 250 is being pulled out or wound, if the power receiving cord 250 is caught by an obstacle or the like and cannot be moved, the torque of the electric motor 620 is reduced to zero.
第1しきい値SH1、第2しきい値SH2および第3しきい値SH3は、開発者により予め定められる任意の値である。第1しきい値SH1、第2しきい値SH2、第3しきい値SH3の順に大きくなるようにこれらの値が定められる。
The first threshold value SH1, the second threshold value SH2, and the third threshold value SH3 are arbitrary values predetermined by the developer. These values are determined so as to increase in the order of the first threshold value SH1, the second threshold value SH2, and the third threshold value SH3.
図2に戻って、電動モータ620によって、受電用コード250が引き出される方向にコードリール610を回転させる際は、バッテリ640に蓄えられた電力が電動モータ620に供給される。一方、電動モータ620が発電した電力は、バッテリ640に供給され、バッテリ640が充電される。
Returning to FIG. 2, when the cord reel 610 is rotated by the electric motor 620 in the direction in which the power receiving cord 250 is pulled out, the electric power stored in the battery 640 is supplied to the electric motor 620. On the other hand, the electric power generated by the electric motor 620 is supplied to the battery 640 and the battery 640 is charged.
電動モータ620が発電すると、制御ユニット650に接続されたランプ652が点灯または点滅される。これにより、電動モータ620が発電していることが利用者に報知される。スピーカから音を発することによって、電動モータ620が発電していることを利用者に報知するようにしてもよい。
When the electric motor 620 generates power, the lamp 652 connected to the control unit 650 is turned on or blinked. This notifies the user that the electric motor 620 is generating power. You may make it alert | report to a user that the electric motor 620 is generating electric power by emitting a sound from a speaker.
さらに、受電用コード250を引き出している間、または巻き取っている間において、障害物等に受電用コード250が引っかかり、コードリール610の回転速度が零まで減速すると、警報装置654から警告音が発せられる。これにより、コードリール610の回転速度が零まで減速したことが利用者に報知される。ランプ等を点灯または点滅することによって、光を用いてコードリール610の回転速度が零まで減速したことを利用者に報知するようにしてもよい。
Further, when the power receiving cord 250 is caught by an obstacle or the like while the power receiving cord 250 is being pulled out or wound, and the rotational speed of the cord reel 610 is reduced to zero, a warning sound is output from the alarm device 654. Be emitted. As a result, the user is notified that the rotation speed of the cord reel 610 has been reduced to zero. A user may be informed that the rotational speed of the cord reel 610 has been reduced to zero using light by turning on or blinking a lamp or the like.
