Description

補助動力付き移動機器Mobile equipment with auxiliary power
　この発明は、補助動力付き移動機器に関し、特に、たとえば、補助動力付き自転車に関する。 The present invention relates to a mobile device with auxiliary power, and more particularly to a bicycle with auxiliary power, for example.
　従来、補助動力付き移動機器としての、たとえば、補助動力付き自転車の駆動系は、人力駆動系と電気駆動系とが並列に設けられている。そして、このような人力による踏力の変化に対応して電気駆動系の出力を制御する補助動力付き自転車において、省エネルギーモードに切り替えるような制御システムを備えた補助動力付き自転車が提案されている。図７は、このような従来の補助動力付き自転車の制御システムの構成を示すブロック図である（特許文献１を参照）。 Conventionally, as a mobile device with auxiliary power, for example, a driving system of a bicycle with auxiliary power is provided with a human power driving system and an electric driving system in parallel. And in the bicycle with an auxiliary power which controls the output of an electric drive system corresponding to the change of the treading force by such a human power, the bicycle with an auxiliary power provided with the control system which switches to an energy saving mode is proposed. FIG. 7 is a block diagram showing the configuration of such a conventional control system for a bicycle with auxiliary power (see Patent Document 1).
　この制御システム１は、省エネルギーモードに切り替えるための制御部２を備えている。そして、制御部２は、ＣＰＵ３を有し、このＣＰＵ３には、外部信号判別手段３ａ、第１タイマ３ｂ、第２タイマ３ｃ、省エネ判別手段３ｄ等の機能を有する。外部信号判別手段３ａは、踏力Ｆおよび車速Ｓの各信号が共にそれぞれ一定値以下である場合には、一定時間走行せずに放置しているものと判別し、第１タイマ３ｂを作動させるタイマスタート信号を第１タイマ３ｂに送り、タイマ１を積算させる。省エネ判別手段３ｄは、第１タイマ３ｂの積算値が一定値以上になると、補器制御部４によりランプ等の補器５の作動を切るように作用させる。また、省エネ判別手段３ｄは、第１タイマ３ｂの積算値が一定値以上になると第２タイマ３ｃによる積算を開始し、第２タイマ３ｃの積算値が一定値以上になると、メインスイッチ６を切ることで、省エネルギーモードに切り替わる。 The control system 1 includes a control unit 2 for switching to the energy saving mode. The control unit 2 includes a CPU 3, and the CPU 3 has functions such as an external signal determination unit 3a, a first timer 3b, a second timer 3c, and an energy saving determination unit 3d. The external signal discriminating means 3a discriminates that the pedaling force F and the vehicle speed S are both equal to or less than a predetermined value and determines that the pedal is left unmoved for a predetermined time, and activates the first timer 3b. A start signal is sent to the first timer 3b, and the timer 1 is integrated. When the integrated value of the first timer 3b reaches a certain value or more, the energy saving determination unit 3d causes the auxiliary device control unit 4 to turn off the operation of the auxiliary device 5 such as a lamp. Further, the energy saving discriminating means 3d starts integration by the second timer 3c when the integrated value of the first timer 3b becomes equal to or greater than a certain value, and turns off the main switch 6 when the accumulated value of the second timer 3c becomes equal to or greater than the certain value. This will switch to the energy saving mode.

　上述したように、特許文献１に記載の制御システム１では、メインスイッチ６をオンにしたまま一定時間以上走行せずに放置すると自動的に省エネルギーモードに切り替える。しかしながら、一定時間放置したことを検出するためには、制御システム１において構成されるような、省エネルギーモードに切り替えるための制御部２が別途必要となることから、コストが増加するといった問題があった。また、このような制御システム１では、省エネルギーモードに切り替えるための制御部２を駆動するため、その際、電力を消費してしまうといった問題があった。 As described above, the control system 1 described in Patent Document 1 automatically switches to the energy saving mode when the main switch 6 is turned on and left without traveling for a certain period of time or longer. However, in order to detect that it has been left for a certain period of time, a separate control unit 2 for switching to the energy saving mode, which is configured in the control system 1, is required, which increases the cost. . Moreover, in such a control system 1, since the control part 2 for switching to an energy saving mode is driven, there existed a problem that electric power was consumed in that case.

It is provided to do. That is, when the bicycle 10 with auxiliary power is parked using the kickstand 80, the electrical connection between the motor 26a and the battery 28a is disconnected by the switch 90a. Blocked. On the other hand, when the bicycle 10 with auxiliary power of the kickstand 80 is parked, the motor 90a and the battery 28a are electrically connected by the switch 90a, so that the circuit of the controller 90 is energized. .
　なお、停止状態維持手段が停止状態を維持する機能と停止状態を解除する動作として、それぞれ鍵の旋錠および解錠の動作により行うようにしてもよい。すなわち、鍵を旋錠すると停止状態が維持されるため、このようなときは、スイッチ９０ａはオフ状態となりモータ２６ａとバッテリ２８ａとの電気的接続が切断されることから、制御部９０の回路内の通電が遮断される。他方、鍵を解錠すると停止状態が解除されるため、スイッチ９０ａはオン状態となりモータ２６ａとバッテリ２８ａとの電気的接続が得られることから、制御部９０の回路が通電状態となる。 In addition, you may be made to perform by the operation | movement of locking and unlocking of a key, respectively as a function which a stop state maintenance means maintains a stop state, and the operation | movement which cancel | releases a stop state. That is, when the key is locked, the stopped state is maintained. In such a case, the switch 90a is turned off, and the electrical connection between the motor 26a and the battery 28a is disconnected. Power is cut off. On the other hand, since the stop state is released when the key is unlocked, the switch 90a is turned on and an electrical connection between the motor 26a and the battery 28a is obtained, so that the circuit of the control unit 90 is energized.
　次に、図３に示される本発明にかかる補助動力付き自転車１０の一実施の形態の動力系統図について説明する。補助動力付き自転車１０における動力系統には、人力駆動系と電気駆動系とが並列に設けられている。 Next, a power system diagram of an embodiment of the bicycle 10 with auxiliary power according to the present invention shown in FIG. 3 will be described. The power system in the bicycle 10 with auxiliary power is provided with a human power drive system and an electric drive system in parallel.
　人力駆動系においては、まず、人力により、ペダル５６ｃおよびクランク５６ｂを介してクランク軸５６ａが回転される。クランク軸５６ａの回転は、一方向クラッチ５６ｄから遊星歯車機構を介して駆動軸５８に伝えられる。すなわち、動力ユニット部５０における遊星歯車機構により、遊星歯車からペダル踏力が入力され、リング歯車から駆動軸５８に踏力が出力される。
　一方、電気駆動系においては、モータ２６ａの回転が、一方向クラッチ２６ｂおよび減速機２６ｃを介して駆動軸５８に伝えられる。
　そして、人力駆動系、電気駆動系のそれぞれから駆動軸５８に伝えられた回転は、一方向クラッチ７４を介して後輪７０に伝えられる。 In the human power drive system, first, the crankshaft 56a is rotated by the human power through the pedal 56c and the crank 56b. The rotation of the crankshaft 56a is transmitted from the one-way clutch 56d to the drive shaft 58 via the planetary gear mechanism. That is, by the planetary gear mechanism in the power unit 50, the pedal depression force is input from the planetary gear, and the pedaling force is output from the ring gear to the drive shaft 58.
On the other hand, in the electric drive system, the rotation of the motor 26a is transmitted to the drive shaft 58 via the one-way clutch 26b and the speed reducer 26c.
Then, the rotation transmitted to the drive shaft 58 from each of the human power drive system and the electric drive system is transmitted to the rear wheel 70 via the one-way clutch 74.

　次に、本発明にかかる補助動力付き自転車の一実施の形態の制御システムについて説明する。図４は、本発明にかかる補助動力付き自転車１０の一実施の形態の制御システム１００の構成を示すブロック図である。 (Control system)
Next, a control system of an embodiment of a bicycle with auxiliary power according to the present invention will be described. FIG. 4 is a block diagram showing a configuration of the control system 100 of the embodiment of the bicycle 10 with auxiliary power according to the present invention.
　図４に示す制御システム１００は、概略、モータ２６ａと、バッテリ２８ａと、ポテンショメータ５０ａと、速度センサ５０ｂと、制御部９０と、を備えている。制御部９０は、図４において、一点鎖線で囲まれて示されている。 4 schematically includes a motor 26a, a battery 28a, a potentiometer 50a, a speed sensor 50b, and a control unit 90. The control system 100 shown in FIG. The control unit 90 is surrounded by a one-dot chain line in FIG.
　モータ２６ａは、補助動力付き自転車１０をアシストするために設けられ、バッテリ２８ａは、モータ２６ａ等に対して電力を供給するために設けられる。 The motor 26a is provided to assist the bicycle 10 with auxiliary power, and the battery 28a is provided to supply power to the motor 26a and the like.
　ポテンショメータ５０ａは、上述したように、動力ユニット部５０に設けられる遊星歯車機構における中央のサン歯車に加わるトルクを検出することにより踏力Ｆを検出するために設けられる。また、速度センサ５０ｂは、クランク軸５６ａの回転速度から車速Ｓを検出するために設けられる。動力ユニット部５０におけるポテンショメータ５０ａで検出した踏力Ｆは、制御部９０に入力される。この制御部９０は、この踏力Ｆに基づいてモータ電流を制御し、モータ出力すなわちモータトルクＴMを発生させる。 As described above, the potentiometer 50a is provided to detect the pedal force F by detecting the torque applied to the central sun gear in the planetary gear mechanism provided in the power unit 50. The speed sensor 50b is provided for detecting the vehicle speed S from the rotational speed of the crankshaft 56a. The pedaling force F detected by the potentiometer 50 a in the power unit 50 is input to the control unit 90. The control unit 90 controls the motor current based on the pedal force F, to generate a motor output or motor torque T M.
　制御部９０は、スイッチ９０ａと、スイッチング回路９０ｂと、ゲート回路９０ｃと、フライホールダイオード９０ｄと、シャント９０ｅと、ＣＰＵ９０ｆと、を備えている。 The control unit 90 includes a switch 90a, a switching circuit 90b, a gate circuit 90c, a flyhole diode 90d, a shunt 90e, and a CPU 90f.
　スイッチ９０ａは、モータ２６ａとバッテリ２８ａとの間の電気的接続の切り替えをするために設けられる。 The switch 90a is provided for switching the electrical connection between the motor 26a and the battery 28a.
　スイッチング回路９０ｂは、後述するゲート回路９０ｃからのゲート信号ｇに基づき駆動される。スイッチング回路９０ｂは、モータ２６ａとバッテリ２８ａと共に閉回路を形成し、この閉回路が主回路９２となる。スイッチング回路９０ｂは、たとえば、ＭＯＳ－ＦＥＴで構成される。また、モータ２６ａにはフライホールダイオード９０ｄが並列接続される。また、主回路９２は、スイッチ９０ａおよび電流検出用のシャント９０ｅが取り付けられている。 The switching circuit 90b is driven based on a gate signal g from a gate circuit 90c described later. The switching circuit 90b forms a closed circuit together with the motor 26a and the battery 28a, and this closed circuit becomes the main circuit 92. The switching circuit 90b is composed of, for example, a MOS-FET. Further, the flywheel diode 90d is connected in parallel to the motor 26a. The main circuit 92 is provided with a switch 90a and a current detecting shunt 90e.
　ＣＰＵ９０ｆは、ポテンショメータ５０ａにより検出される踏力Ｆや速度センサ５０ｂにより検出される車速Ｓなどに基づいてモータ２６ａの出力（トルク）ＴMの指令値ｉを出力するために設けられる。すなわち、ＣＰＵ９０ｆは、検出された踏力Ｆの周期的増減に同期して、モータ２６ａの出力（トルク）ＴMを周期的に増減させるように指令値ｉを出力する。なお、ＣＰＵ９０ｆは、検出された車速Ｓが一定になった場合に、モータ出力ＴMを制限して車速Ｓを制限するように制御してもよい。 CPU90f is provided for outputting a command value i of the output (torque) T M of the motor 26a and the like based on the vehicle speed S detected by the pedal force F and the speed sensor 50b detected by the potentiometer 50a. That, CPU90f in synchronization with the periodic increase and decrease of the detected pedaling force F, the output of the motor 26a (torque) T M outputs a command value i so as to cyclically increase and decrease. Incidentally, CPU90f, when the detected vehicle speed S becomes constant may be controlled to limit the vehicle speed S by limiting the motor output T M.
　ゲート回路９０ｃは、ＣＰＵ９０ｆから供給されるデューティ比が変化する指令値ｉに対応してスイッチング回路９０ｂを駆動するゲート信号ｇを出力するために設けられる。ゲート回路９０ｃは、モータ出力ＴMを増加させる時には、指令値ｉの（オン時間）／（オフ時間＋オン時間）の値（デューティという）を大きくするように動作する。 The gate circuit 90c is provided to output a gate signal g for driving the switching circuit 90b in response to a command value i supplied from the CPU 90f that changes the duty ratio. The gate circuit 90c, when increasing the motor output T M operates such that the value of the command value i (on-time) / (OFF time + ON time) (called duty) is increased.
　ゲート回路９０ｃが指令値ｉに基づいて出力するゲート信号ｇは、スイッチング回路９０ｂのスイッチング素子に送られ、各スイッチング素子を選択的にオン・オフさせる。 The gate signal g output from the gate circuit 90c based on the command value i is sent to the switching element of the switching circuit 90b to selectively turn on / off each switching element.
　本実施の形態にかかる補助動力付き自転車１０によると、モータ２６ａとバッテリ２８ａとの電気的接続についてキックスタンド８０の動作を用いて切断することができるので、補助動力付き自転車１０を駐輪する状態にした場合に、確実にバッテリの容量の低下を抑制することができる。このように、従来のように、補助動力付き自転車１０を使用していないことを検知するために別途制御回路を準備する必要がないことから、コストを低減させることができる。さらに、制御部９０のオン・オフの動作が電気的制御ではないため、別途準備された制御回路自体による電力の消費も生じない。 According to the bicycle 10 with auxiliary power according to the present embodiment, the electric connection between the motor 26a and the battery 28a can be disconnected using the operation of the kickstand 80, so that the bicycle 10 with auxiliary power is parked. In this case, it is possible to reliably suppress a decrease in battery capacity. Thus, since it is not necessary to prepare a separate control circuit for detecting that the bicycle 10 with auxiliary power is not used as in the prior art, the cost can be reduced. Furthermore, since the on / off operation of the control unit 90 is not electrical control, power consumption by the separately prepared control circuit itself does not occur.
　次に、本発明にかかる補助動力付き移動機器である補助動力付き自転車の第２の実施の形態について説明する。図５ａは、本発明にかかる補助動力付き自転車１１０の第２の実施の形態において用いられるスイッチ９０ａを切り替えるための載置部４０´を示す側面図である。また、図５ｂは、本発明にかかる補助動力付き自転車１１０の第２の実施の形態において用いられるスイッチ９０ａを切り替えるための載置部４０´の動作を示し、（ａ）は、サドル４４から人が降りたときの載置部４０´の状態を示した断面図解図であり、（ｂ）は、サドル４４に人が乗ったときの載置部４０´の状態を示した断面図解図である。 Next, a second embodiment of a bicycle with auxiliary power which is a mobile device with auxiliary power according to the present invention will be described. FIG. 5 a is a side view showing a placement portion 40 ′ for switching the switch 90 a used in the second embodiment of the bicycle 110 with auxiliary power according to the present invention. FIG. 5b shows the operation of the mounting portion 40 ′ for switching the switch 90a used in the second embodiment of the bicycle 110 with auxiliary power according to the present invention. FIG. 6 is a cross-sectional view showing the state of the mounting portion 40 ′ when the vehicle gets down, and (b) is a cross-sectional schematic view showing the state of the mounting portion 40 ′ when a person gets on the saddle 44. .
　なお、第２の実施の形態にかかる補助動力付き自転車１１０における載置部４０´以外の構成は、第１の実施の形態にかかる補助動力付き自転車１０と同一であるので、それらの同一部分の構成の説明を省略する。また、補助動力付き自転車１１０においては、スイッチボックス８２は、必ずしも備えていなくても良い。 In addition, since structures other than mounting part 40 'in the bicycle 110 with auxiliary power concerning the second embodiment are the same as those of the bicycle 10 with auxiliary power according to the first embodiment, The description of the configuration is omitted. Moreover, in the bicycle 110 with auxiliary power, the switch box 82 is not necessarily provided.
　第２の実施の形態にかかる補助動力付き自転車１１０における載置部４０´は、シートチューブ２４の上端で支持されている。載置部４０´は、シートポスト４２、サドル４４、およびサドル４４に人が着座したり降りたりする動作により切り替えられるスイッチ９０ａが収容されるスイッチボックス４６により構成される。スイッチボックス４６は、図５ｂに示すように、載置部４０´におけるサドル４４の下部側に取り付けられており、スイッチボックス４６の下端側は、シートポスト４２の一方端側に固定されている。スイッチボックス４６には、サドル４４を支持するためのサドル支持部材４６ａ、サドル支持部材４６ａを支持するための弾性部材４６ｂ、およびスイッチ９０ａが収容される。弾性部材４６ｂは、たとえば、コイルバネが用いられる。なお、スイッチボックス４６に収容されるスイッチ９０ａに対して、どの程度押されることでオン状態あるいはオフ状態と判断するかの条件（所定値）は、制御部９０に設けられたメモリ（図示せず）に予め設定されている。 The mounting portion 40 ′ in the auxiliary power-equipped bicycle 110 according to the second embodiment is supported by the upper end of the seat tube 24. The mounting portion 40 ′ is configured by a seat post 42, a saddle 44, and a switch box 46 that accommodates a switch 90 a that is switched by an operation in which a person sits on or goes down from the saddle 44. As shown in FIG. 5 b, the switch box 46 is attached to the lower side of the saddle 44 in the placement portion 40 ′, and the lower end side of the switch box 46 is fixed to one end side of the seat post 42. The switch box 46 accommodates a saddle support member 46a for supporting the saddle 44, an elastic member 46b for supporting the saddle support member 46a, and a switch 90a. As the elastic member 46b, for example, a coil spring is used. Note that a condition (predetermined value) indicating how much the switch 90a accommodated in the switch box 46 is pressed to determine whether the switch 90a is on or off is a memory (not shown) provided in the control unit 90. ) In advance.
　そして、図５ｂに示すように、サドル４４は、サドル支持部材４６ａを介して弾性部材４６ｂにより上方向に付勢されることで、スイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が切断されるので、制御部９０の回路内の通電が遮断される。すなわち、この状態は、人が補助動力付き自転車１１０から降りた後の状態である（すなわち、移動準備状態が解除された状態である）。他方、人がサドル４４に着座することにより、弾性部材４６ｂが縮むことでサドル支持部材４６ａによりスイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が得られることから、制御部９０の回路が通電状態となる。 Then, as shown in FIG. 5b, the saddle 44 is biased upward by the elastic member 46b via the saddle support member 46a, so that the electrical connection between the motor 26a and the battery 28a is cut by the switch 90a. Therefore, the power supply in the circuit of the control unit 90 is cut off. That is, this state is a state after a person gets off the bicycle 110 with auxiliary power (that is, a state in which the movement preparation state is released). On the other hand, when the person sits on the saddle 44, the elastic member 46b contracts, and the saddle support member 46a allows the switch 90a to electrically connect the motor 26a and the battery 28a. It becomes a state.
　本実施の形態にかかる補助動力付き自転車１１０によると、モータ２６ａとバッテリ２８ａとの電気的接続について、載置部４０´における動作を用いて切断することができるので、補助動力付き自転車１１０から人が降りた場合に、確実にバッテリの容量の低下を抑制することができる。このように、従来のように、補助動力付き自転車１１０を使用していないことを検知するために別途制御回路を準備する必要がないことから、コストを低減させることができる。さらに、制御部９０のオン・オフの動作が電気的制御ではないため、別途準備された制御回路自体による電力の消費も生じない。 According to the bicycle 110 with auxiliary power according to the present embodiment, the electric connection between the motor 26a and the battery 28a can be disconnected using the operation of the mounting portion 40 '. When the battery gets off, it is possible to reliably suppress a decrease in battery capacity. As described above, since it is not necessary to prepare a separate control circuit for detecting that the bicycle 110 with auxiliary power is not used, as in the prior art, the cost can be reduced. Furthermore, since the on / off operation of the control unit 90 is not electrical control, power consumption by the separately prepared control circuit itself does not occur.
　次に、本発明にかかる補助動力付き移動機器である補助動力付き自転車の第３の実施の形態について説明する。図６ａは、本発明にかかる補助動力付き自転車２１０の第３の実施の形態の把持部３０´を示す正面図である。また、図６ｂは、本発明にかかる補助動力付き自転車２１０の第３の実施の形態において用いられるスイッチ９０ａを切り替えるためのハンドルグリップ３６ｂを示す断面図解図である。 Next, a third embodiment of a bicycle with auxiliary power that is a mobile device with auxiliary power according to the present invention will be described. FIG. 6a is a front view showing a grip 30 'of a third embodiment of a bicycle 210 with auxiliary power according to the present invention. 6b is a cross-sectional view showing a handlebar grip 36b for switching a switch 90a used in the third embodiment of the bicycle 210 with auxiliary power according to the present invention.
　なお、第３の実施の形態にかかる補助動力付き自転車２１０における把持部３０´以外の構成は、第１の実施の形態にかかる補助動力付き自転車１０と同一であるので、それらの同一部分の構成の説明を省略する。また、補助動力付き自転車２１０においては、スイッチボックス８２は、必ずしも備えていなくても良い。 The configuration of the bicycle with auxiliary power 210 according to the third embodiment other than the grip portion 30 'is the same as that of the bicycle 10 with auxiliary power according to the first embodiment. The description of is omitted. Moreover, in the bicycle 210 with auxiliary power, the switch box 82 is not necessarily provided.
　把持部３０´は、ヘッドパイプ２２に支持されている。把持部３０´は、ヘッドパイプ２２の上部に固定されたハンドルステム３２と、ハンドルステム３２に固定されたハンドルバー３４とを有している。ハンドルバー３４の両端には、一対のハンドルグリップ３６ａ，３６ｂが装着されている。ハンドルグリップ３６ａ，３６ｂの内部には、スイッチ９０ａが設置されている。このスイッチ９０ａは、補助動力付き自転車２１０の使用者が握ったり放したりすることで、オン状態となったりオフ状態となったりすることを可能とするように設置されている。なお、ハンドルグリップ３６ａ，３６ｂの内部に設置されるスイッチ９０ａに対して、どの程度押されることでオン状態あるいはオフ状態と判断するかの条件（所定値）は、制御部９０に設けられたメモリ（図示せず）に予め設定されている。 The grip portion 30 ′ is supported by the head pipe 22. The grip portion 30 ′ has a handle stem 32 fixed to the top of the head pipe 22 and a handle bar 34 fixed to the handle stem 32. A pair of handle grips 36 a and 36 b are attached to both ends of the handle bar 34. A switch 90a is installed inside the handle grips 36a and 36b. This switch 90a is installed so that the user of the bicycle 210 with auxiliary power can be turned on or off by gripping or releasing it. Note that a condition (predetermined value) regarding how much the switch 90a installed inside the handlebar grips 36a, 36b is determined to be in an on state or an off state is determined by a memory provided in the control unit 90. (Not shown) is preset.
　たとえば、図６ｂに示すように、ハンドルグリップ３６ｂが握られることで、ハンドルグリップ３６ｂ内に設置されているスイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が得られることから、制御部９０の回路が通電状態となる。他方、ハンドルグリップ３６ｂを放すと（すなわち、移動準備状態が解除されると）、ハンドルグリップ３６ｂ内に設置されているスイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が切断されることから、制御部９０の回路内の通電が遮断される。なお、スイッチ９０ａは、ハンドルグリップ３６ａあるいはハンドルグリップ３６ｂの少なくともいずれか一方に配置されていればよい。したがって、ハンドルグリップ３６ａおよびハンドルグリップ３６ｂのいずれの内部にもスイッチ９０ａが設置されてもよい。 For example, as shown in FIG. 6b, since the handle grip 36b is gripped, the electrical connection between the motor 26a and the battery 28a is obtained by the switch 90a installed in the handle grip 36b. The circuit is energized. On the other hand, when the handle grip 36b is released (that is, when the movement ready state is released), the electrical connection between the motor 26a and the battery 28a is disconnected by the switch 90a installed in the handle grip 36b. The energization in the circuit of the control unit 90 is cut off. The switch 90a may be disposed on at least one of the handle grip 36a and the handle grip 36b. Therefore, the switch 90a may be installed inside either the handle grip 36a or the handle grip 36b.
　本実施の形態にかかる補助動力付き自転車２１０によると、モータ２６ａとバッテリ２８ａとの電気的接続について、補助動力付き自転車２１０の使用者がハンドルグリップ３６ａ，３６ｂを放す動作により切断することができるので、補助動力付き自転車２１０から人が降りた場合に、確実にバッテリの容量の低下を抑制することができる。このように、従来のように、補助動力付き自転車２１０を使用していないことを検知するために別途制御回路を準備する必要がないことから、コストを低減させることができる。さらに、制御部９０のオン・オフの動作が電気的制御ではないため、別途準備された制御回路自体による電力の消費も生じない。 According to the bicycle with auxiliary power 210 according to the present embodiment, the user of the bicycle with auxiliary power 210 can disconnect the electrical connection between the motor 26a and the battery 28a by the operation of releasing the handle grips 36a and 36b. When the person gets off the bicycle with auxiliary power 210, the battery capacity can be reliably prevented from decreasing. As described above, since it is not necessary to prepare a separate control circuit in order to detect that the bicycle with auxiliary power 210 is not used as in the prior art, the cost can be reduced. Furthermore, since the on / off operation of the control unit 90 is not electrical control, power consumption by the separately prepared control circuit itself does not occur.
　次に、本発明にかかる補助動力付き移動機器である補助動力付き自転車の第４の実施の形態について説明する。図７ａは、本発明にかかる補助動力付き自転車３１０の第４の実施の形態において用いられるスイッチ９０ａを切り替えるためのペダル５６ｃ´を示す側面図である。また、図７ｂは、本発明にかかる補助動力付き自転車３１０の第４の実施の形態において用いられるスイッチ９０ａを切り替えるためのペダル５６ｃ´の拡大図を示す断面図解図である。 Next, a description will be given of a fourth embodiment of a bicycle with auxiliary power which is a mobile device with auxiliary power according to the present invention. FIG. 7 a is a side view showing a pedal 56 c ′ for switching the switch 90 a used in the fourth embodiment of the bicycle 310 with auxiliary power according to the present invention. FIG. 7B is a cross-sectional view showing an enlarged view of the pedal 56c ′ for switching the switch 90a used in the fourth embodiment of the bicycle 310 with auxiliary power according to the present invention.
　なお、第４の実施の形態にかかる補助動力付き自転車３１０におけるペダル５６ｃ´以外の構成において、第１の実施の形態にかかる補助動力付き自転車１０と同一である構成については、説明を省略する。また、補助動力付き自転車３１０においては、スイッチボックス８２は、必ずしも備えていなくても良い。 In addition, description is abbreviate | omitted about the structure which is the same as that of the bicycle 10 with auxiliary power concerning 1st Embodiment in structures other than the pedal 56c 'in the bicycle 310 with auxiliary power concerning 4th Embodiment. Further, in the bicycle 310 with auxiliary power, the switch box 82 is not necessarily provided.
　第４の実施の形態にかかるペダル５６ｃ´は、クランク５６ｂの先端にペダル軸５６ｅを中心に回転自在に取り付けられている。図７ｂに示すように、ペダル５６ｃ´において、足が載せられる一方主面および他方主面には、可動なスイッチカバー５６ｆが配置されている。スイッチカバー５６ｆには、弾性部材５６ｇ、およびスイッチ９０ａが収容される。弾性部材５６ｇは、たとえば、コイルバネが用いられる。スイッチ９０ａは、ペダル５６ｃ´から、足を離すことで、ペダル５６ｃ´への荷重が所定値以下となるかまたは消滅するので、オフ状態となり、足を載せることで、ペダル５６ｃ´への荷重が所定値より大きいかまたは発生するので、オン状態となるように設置されている。なお、このような、スイッチカバー５６ｆに収容されるスイッチ９０ａに対して、どの程度押されることでオン状態あるいはオフ状態と判断するかの条件（所定値）は、制御部９０に設けられたメモリ（図示せず）に予め設定されている。 The pedal 56c 'according to the fourth embodiment is attached to the tip of the crank 56b so as to be rotatable around the pedal shaft 56e. As shown in FIG. 7b, in the pedal 56c ', a movable switch cover 56f is arranged on one main surface and the other main surface on which the foot is placed. An elastic member 56g and a switch 90a are accommodated in the switch cover 56f. As the elastic member 56g, for example, a coil spring is used. When the switch 90a is released from the pedal 56c ′, the load on the pedal 56c ′ becomes equal to or less than a predetermined value or disappears. Therefore, the switch 90a is turned off and the load on the pedal 56c ′ is reduced by putting the foot on the switch 90a. Since it is larger than a predetermined value or occurs, it is installed so as to be in an on state. Note that the condition (predetermined value) regarding how much the switch 90a accommodated in the switch cover 56f is determined to be in an on state or an off state is determined by a memory provided in the control unit 90. (Not shown) is preset.
　たとえば、図７ｂに示すように、ペダル５６ｃ´に足が載せられることで、スイッチカバー５６ｆ内に設置されているスイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が得られることから、制御部９０の回路が通電状態となる。他方、ペダル５６ｃ´から足を離すと（すなわち、移動準備状態が解除されると）、スイッチカバー５６ｆ内に設置されているスイッチ９０ａによりモータ２６ａとバッテリ２８ａとの電気的接続が切断されることから、制御部９０の回路内の通電が遮断される。 For example, as shown in FIG. 7b, since the foot is placed on the pedal 56c ′, the switch 90a installed in the switch cover 56f provides an electrical connection between the motor 26a and the battery 28a. 90 circuits are energized. On the other hand, when the foot is released from the pedal 56c '(that is, when the movement preparation state is released), the electrical connection between the motor 26a and the battery 28a is disconnected by the switch 90a installed in the switch cover 56f. Thus, energization in the circuit of the control unit 90 is cut off.
　本実施の形態にかかる補助動力付き自転車３１０によると、モータ２６ａとバッテリ２８ａとの電気的接続について、補助動力付き自転車３１０の使用者がペダル５６ｃ´から足を降ろす動作により切断することができるので、補助動力付き自転車３１０から人が降りた場合に、確実にバッテリの容量の低下を抑制することができる。このように、従来のように、補助動力付き自転車３１０を使用していないことを検知するために別途制御回路を準備する必要がないことから、コストを低減させることができる。さらに、制御部９０のオン・オフの動作が電気的制御ではないため、別途準備された制御回路自体による電力の消費も生じない。 According to the bicycle 310 with auxiliary power according to the present embodiment, the electric connection between the motor 26a and the battery 28a can be disconnected by the user of the bicycle 310 with auxiliary power dropping the foot from the pedal 56c ′. When the person gets off the bicycle 310 with auxiliary power, the battery capacity can be reliably prevented from decreasing. As described above, since it is not necessary to prepare a separate control circuit to detect that the auxiliary powered bicycle 310 is not used as in the prior art, the cost can be reduced. Furthermore, since the on / off operation of the control unit 90 is not electrical control, power consumption by the separately prepared control circuit itself does not occur.
　さらに、第１の実施の形態ないし第４の実施の形態において説明された、キックスタンド８０、サドル４４（あるいは荷物を載せる積載台）、ハンドルグリップ３６ａ，３６ｂおよびペダル５６ｃ´にそれぞれスイッチ９０ａが設けられた実施の形態を適宜組み合わせた補助動力付き自転車が実施されてもよい。この場合、それぞれのスイッチ９０ａは、制御部９０において直列に接続される。たとえば、以下に記載するような状況に対して、より緻密なモータ２６ａとバッテリ２８ａとの電気的接続に対するオン・オフの切り替えを可能にすることができる。 Further, the switch 90a is provided in each of the kick stand 80, the saddle 44 (or the load platform on which the load is loaded), the handle grips 36a and 36b, and the pedal 56c 'described in the first to fourth embodiments. A bicycle with auxiliary power may be implemented by appropriately combining the embodiments described. In this case, the respective switches 90 a are connected in series in the control unit 90. For example, in a situation as described below, it is possible to switch on / off for a more precise electrical connection between the motor 26a and the battery 28a.
　たとえば、キックスタンド８０を立てた状態で駐輪して補助動力付き自転車に荷物を搭載している場合、積載台に設けられたスイッチ９０ａはオンの状態となるが、補助動力付き自転車の使用者は、補助動力付き自転車を降りているため、ハンドルグリップ３６ａ，３６ｂは放され、ペダル５６ｃ´にも足が載っておらず、キックスタンド８０が立てられているので、それぞれのスイッチ９０ａは、オフの状態である。したがって、制御部９０の回路の全体としては、オフの状態となり、モータ２６ａとバッテリ２８ａとの電気的接続を切断することができることから、制御部９０の回路内の通電を遮断することができる。その結果、補助動力付き自転車のバッテリの容量の低下を、確実に抑制することができる。 For example, when the bicycle is parked with the kickstand 80 in a standing state and a load is loaded on a bicycle with auxiliary power, the switch 90a provided on the loading table is turned on. Since the bicycle with auxiliary power is dismounted, the handlebar grips 36a and 36b are released, the foot is not placed on the pedal 56c ', and the kickstand 80 is set up, so that each switch 90a is turned off. It is a state. Accordingly, the entire circuit of the control unit 90 is turned off, and the electrical connection between the motor 26a and the battery 28a can be cut off. Therefore, the energization in the circuit of the control unit 90 can be cut off. As a result, it is possible to reliably suppress a reduction in the battery capacity of the bicycle with auxiliary power.
　また、補助動力付き自転車の使用者がその補助動力付き自転車から降りて手押ししながら歩いている場合、キックスタンド８０は駐輪状態が解除されており、ハンドルグリップ３６ａ，３６ｂは握られていることから、それぞれに設けられたスイッチ９０ａはオンの状態となるが、サドル４４には補助動力付き自転車の使用者は載っておらず、ペダル５６ｃ´には足が載っていないので、それぞれの設けられたスイッチ９０ａはオフの状態である。したがって、制御部９０の回路の全体としては、オフの状態となり、モータ２６ａとバッテリ２８ａとの電気的接続を切断することができることから、制御部９０の回路内の通電を遮断することができる。その結果、補助動力付き自転車のバッテリの容量の低下を、確実に抑制することができる。 In addition, when a user of a bicycle with auxiliary power gets off the bicycle with auxiliary power and walks while pushing, the kickstand 80 is released from the parking state and the handle grips 36a and 36b are gripped. Therefore, the switch 90a provided on each of the switches is turned on, but the saddle 44 does not have a user of the bicycle with auxiliary power, and the pedal 56c 'has no foot on it. The switch 90a is off. Accordingly, the entire circuit of the control unit 90 is turned off, and the electrical connection between the motor 26a and the battery 28a can be cut off. Therefore, the energization in the circuit of the control unit 90 can be cut off. As a result, it is possible to reliably suppress a reduction in the battery capacity of the bicycle with auxiliary power.
　さらに、信号待ちのときなど自転車にまたがって停車中あるいは下り坂の場合、キックスタンド８０は駐輪状態が解除されており、ハンドルグリップ３６ａ，３６ｂは握られており、サドル４４には補助動力付き自転車の使用者が載っているので、それぞれに設けられたスイッチ９０ａはオンの状態となるが、ペダル５６ｃ´には足が載っていないので、ペダル５６ｃ´に設けられたスイッチ９０ａはオフの状態である。したがって、制御部９０の回路の全体としては、オフの状態となり、モータ２６ａとバッテリ２８ａとの電気的接続を切断することができることから、制御部９０の回路内の通電を遮断することができる。その結果、補助動力付き自転車のバッテリの容量の低下を、確実に抑制することができる。 Further, when the vehicle is parked across a bicycle or downhill, such as when waiting for a signal, the kickstand 80 is released from the parking state, the handlebar grips 36a and 36b are held, and the saddle 44 has auxiliary power. Since the bicycle user is on, the switch 90a provided on each is turned on, but the foot is not on the pedal 56c ', so the switch 90a provided on the pedal 56c' is off. It is. Accordingly, the entire circuit of the control unit 90 is turned off, and the electrical connection between the motor 26a and the battery 28a can be cut off. Therefore, the energization in the circuit of the control unit 90 can be cut off. As a result, it is possible to reliably suppress a reduction in the battery capacity of the bicycle with auxiliary power.
　したがって、上述したように、第１の実施の形態ないし第４の実施の形態において説明された、キックスタンド８０、サドル４４（あるいは載置台）、ハンドルグリップ３６ａ，３６ｂおよびペダル４４を適宜組み合わせることで、モータ２６ａとバッテリ２８ａとの間の電気的接続を切断する機会を増加させることができることから、キックスタンド８０、サドル４４（あるいは載置台）、ハンドルグリップ３６ａ，３６ｂおよびペダル４４をそれぞれ単独で使用する場合よりも、バッテリの電力消費をさらに抑制することができる。 Therefore, as described above, the kick stand 80, the saddle 44 (or the mounting table), the handle grips 36a and 36b, and the pedal 44 described in the first to fourth embodiments are appropriately combined. Since the chance of disconnecting the electrical connection between the motor 26a and the battery 28a can be increased, the kickstand 80, the saddle 44 (or mounting table), the handle grips 36a and 36b, and the pedal 44 are used independently. The power consumption of the battery can be further suppressed as compared with the case of doing so.
