Description

Translated fromJapanese

本発明は、非接触充電により携帯機器を充電する際に敷くシート部材、シート部材を備えた充電器および携帯機器の充電システムに関する。  The present invention relates to a sheet member spread when charging a portable device by non-contact charging, a charger including the sheet member, and a charging system for the portable device.

充電器と携帯機器との間にケーブルやコネクタなど電気的接続箇所を設けない非接触充電には、磁界結合方式と、電界結合方式とがある。磁界結合方式は、さらに電磁誘導方式と磁界共振方式とに分類される。電磁誘導方式と磁界共振方式では、充電器側のコイルと携帯機器側のコイルを互いに対向配置させて充電器が携帯機器へ送電する点では同じであるが、磁界結合モードが異なる。一方、電界結合方式では、充電器側の電極と携帯機器側の電極との間で容量結合させることによって充電器から携帯機器に送電される。  Non-contact charging in which an electrical connection portion such as a cable or a connector is not provided between the charger and the portable device includes a magnetic field coupling method and an electric field coupling method. The magnetic field coupling method is further classified into an electromagnetic induction method and a magnetic field resonance method. The electromagnetic induction method and the magnetic field resonance method are the same in that the charger-side coil and the portable device-side coil are arranged to face each other and the charger transmits power to the portable device, but the magnetic field coupling modes are different. On the other hand, in the electric field coupling method, power is transmitted from the charger to the portable device by capacitive coupling between the electrode on the charger side and the electrode on the portable device side.

上述した非接触充電では、充電中に携帯機器は充電器に対向配置されている。しかし、携帯機器がバイブレータを備えた携帯電話機の場合、充電中に着信があったときに携帯電話機がバイブレータの振動により移動する場合がある。この場合、携帯電話機が充電器に対向しなくなって、充電器が携帯電話機へ送電できなくなる可能性がある。そこで、充電中の携帯電話機の移動を抑制可能な充電システムが特許文献1に開示されている。特許文献1に開示された充電システムでは、充電器の表面(携帯機器を載せる面)に接続手段としてのゴム面を形成することによって、充電中の携帯電話機の移動を抑制している。  In the non-contact charging described above, the portable device is disposed opposite to the charger during charging. However, when the mobile device is a mobile phone provided with a vibrator, the mobile phone may move due to vibration of the vibrator when an incoming call is received during charging. In this case, the mobile phone may not face the charger, and the charger may not be able to transmit power to the mobile phone. Therefore, Patent Document 1 discloses a charging system capable of suppressing the movement of a mobile phone during charging. In the charging system disclosed in Patent Document 1, the movement of the mobile phone during charging is suppressed by forming a rubber surface as a connecting means on the surface of the charger (the surface on which the portable device is placed).

In the charging system disclosed in Patent Document 1, when a thermosetting rubber is used on the rubber surface formed on the surface of the charger, the thermosetting rubber has a high viscosity due to heat generated in the portable device. , May become hard due to aging. In this case, the mobile phone is more likely to move than before charging.

Thework memory 112 is a RAM (Random Access Memory), and is configured to store data temporarily required for theCPU 110 to execute a program. Thenonvolatile memory 113 is a semiconductor memory in which data can be freely erased and written, and data contents are not lost even when the power is turned off.

Further, the powersupply control unit 124 controls the operation of charging therechargeable battery 129 with the electromotive force generated in thepower receiving coil 128 by controlling the power receivingside control unit 125. The power receivingside control unit 125 controls therectifier circuit 126 and thecommunication circuit 127. Thecommunication circuit 127 notifies thecharger 200 of the reception voltage of theportable device 100 and charging information indicating the charging status of therechargeable battery 129. The power receivingcoil 128 has both a function of receiving power from thecharger 200 and a communication antenna function.

次に、充電器200の電気的構成について説明する。充電器200は、送電側制御部210と、電力伝送回路211と、通信回路212と、送電コイル213と、を有する。送電側制御部210は、電力伝送回路211および通信回路212を制御する。通信回路212は、携帯機器100から送信された各種情報を受信して送電側制御部210に提供する。電力伝送回路211は、送電側制御部210の制御に従って送電コイル213へ通電したり、通電を中断したりする。  Next, the electrical configuration of thecharger 200 will be described. Thecharger 200 includes a power transmissionside control unit 210, apower transmission circuit 211, acommunication circuit 212, and apower transmission coil 213. The power transmissionside control unit 210 controls thepower transmission circuit 211 and thecommunication circuit 212. Thecommunication circuit 212 receives various information transmitted from themobile device 100 and provides it to the power transmissionside control unit 210. Thepower transmission circuit 211 energizes thepower transmission coil 213 or interrupts energization according to the control of the power transmissionside control unit 210.

次に、本実施形態の充電システムの充電動作について説明する。図3は、図1に示す充電システムの充電動作の手順を示すフローチャートである。  Next, the charging operation of the charging system of this embodiment will be described. FIG. 3 is a flowchart showing the procedure of the charging operation of the charging system shown in FIG.

まず、充電器200の送電側制御部210が、充電対象物であるか否か判断する(ステップS1)。具体的には、送電側制御部210は、電力伝送回路211に送電コイル213へ通電させ、送電コイル213のインピーダンスの変化量を検知する。本実施形態では、携帯機器100が絶縁シート部材221のマーク222に配置されたときに受電コイル128が絶縁シート部材221を挟んで送電コイル213に対向配置される。これにより、送電側制御部210に検知されたインピーダンスの変化量が予め設定された許容範囲内となる。この場合、送電側制御部210は、電力伝送回路211に送電コイル213への送電を開始する。すると、電磁誘導により受電コイル128で起電力が発生し、充電式電池129の充電が開始する(ステップS2)。  First, the power transmissionside control unit 210 of thecharger 200 determines whether or not it is a charging target (step S1). Specifically, the power transmissionside control unit 210 causes thepower transmission circuit 211 to energize thepower transmission coil 213 and detects the amount of change in the impedance of thepower transmission coil 213. In the present embodiment, when theportable device 100 is disposed at themark 222 of the insulatingsheet member 221, thepower receiving coil 128 is disposed to face thepower transmitting coil 213 with the insulatingsheet member 221 interposed therebetween. Thereby, the amount of change in impedance detected by the power transmissionside control unit 210 falls within a preset allowable range. In this case, the power transmissionside control unit 210 starts power transmission to thepower transmission circuit 211 to thepower transmission coil 213. Then, an electromotive force is generated in thepower receiving coil 128 by electromagnetic induction, and charging of therechargeable battery 129 starts (step S2).

ステップS1において、インピーダンスの変化量が許容範囲外である場合、送電側制御部210は、電力伝送回路211に送電コイル213への送電を中止させる(ステップS3)。ステップS1からステップS3の動作により、充電器200自身が、シート部材221の上面に載せられた物体が充電対象物なのか金属異物(例えば、鍵)なのか判断し、充電対象物でないと判断した場合には充電を開始しないようにできる。  In step S1, when the amount of change in impedance is outside the allowable range, the power transmissionside control unit 210 causes thepower transmission circuit 211 to stop power transmission to the power transmission coil 213 (step S3). By the operation from step S1 to step S3, thecharger 200 itself determines whether the object placed on the upper surface of thesheet member 221 is a charging object or a metal foreign object (for example, a key), and determines that the object is not a charging object. In some cases, charging can be prevented from starting.

充電開始後、送電側制御部210は、引き続き送電コイル213のインピーダンスの変化量を検知し、検知したインピーダンスの変化量が許容範囲内であるか否か判断している(ステップS4)。インピーダンスの変化量が許容範囲外になると、送電側制御部210は、電力伝送回路211に送電コイル213への送電を中断させる(ステップS5)。インピーダンスの変化量が許容範囲内である場合には、送電側制御部210は、電力伝送回路211に送電コイル213への送電を継続させる(ステップS6)。  After the start of charging, the power transmissionside control unit 210 continues to detect the amount of change in impedance of thepower transmission coil 213, and determines whether or not the detected amount of change in impedance is within an allowable range (step S4). When the amount of change in impedance falls outside the allowable range, the power transmissionside control unit 210 causes thepower transmission circuit 211 to interrupt power transmission to the power transmission coil 213 (step S5). When the amount of change in impedance is within the allowable range, the power transmissionside control unit 210 causes thepower transmission circuit 211 to continue power transmission to the power transmission coil 213 (step S6).

ステップS6の後、送電側制御部210は、携帯機器100の充電が完了したか否か判断する(ステップS7)。ステップS7の具体的な内容について説明する。携帯機器100では、電源制御部124が充電式電池129の充電状況を示す充電情報を受電側制御部125に定期的に通知する。受電側制御部125は、通知された充電情報を通信回路127に受電コイル128から充電器200に無線送信させる。送信された充電情報は、充電器200の送電コイル213を介して通信回路212に受信される。通信回路212は、受信した充電情報を送電側制御部210に出力する。送電側制御部210は、入力された充電情報に示された充電状況に基づいて携帯機器100の充電が完了したか否か判断する。  After step S6, the power transmissionside control unit 210 determines whether charging of themobile device 100 is completed (step S7). Specific contents of step S7 will be described. In theportable device 100, the powersupply control unit 124 periodically notifies the power receivingside control unit 125 of charging information indicating the charging status of therechargeable battery 129. The power receivingside control unit 125 causes thecommunication circuit 127 to wirelessly transmit the notified charging information from thepower receiving coil 128 to thecharger 200. The transmitted charging information is received by thecommunication circuit 212 via thepower transmission coil 213 of thecharger 200. Thecommunication circuit 212 outputs the received charging information to the power transmissionside control unit 210. The power transmissionside control unit 210 determines whether charging of theportable device 100 is completed based on the charging state indicated in the input charging information.

携帯機器100の充電が完了すると、送電側制御部210は電力伝送回路211に送電コイル213への送電を停止させる(ステップS8)。これにより、充電動作が完了する。  When charging of themobile device 100 is completed, the power transmissionside control unit 210 causes thepower transmission circuit 211 to stop power transmission to the power transmission coil 213 (step S8). Thereby, the charging operation is completed.

本実施形態では、携帯機器100の充電が進むにつれて携帯機器100、充電器200の温度が上昇すると、シート部材221が加熱される。本実施形態ではシート部材221は熱可塑性ゴムなので、加熱されたシート部材221は粘度が低くなり柔らかくなる。その結果、シート部材221と携帯機器100の密着性が充電前に比べて増す。したがって、充電中の携帯機器100の移動の抑制効果が向上する。  In this embodiment, when the temperature of theportable device 100 and thecharger 200 rises as the charging of theportable device 100 proceeds, thesheet member 221 is heated. In this embodiment, since thesheet member 221 is a thermoplastic rubber, theheated sheet member 221 has a low viscosity and becomes soft. As a result, the adhesion between thesheet member 221 and theportable device 100 is increased as compared to before charging. Therefore, the effect of suppressing the movement of themobile device 100 during charging is improved.

本実施形態によれば、充電中にバイブレータ116が振動しても携帯機器100がマーク222の外側へ移動する可能性は極めて低くなる。仮に、携帯機器100がマーク222の外側へ移動したとしても、送電側制御部210が、送電コイル213のインピーダンスの変化量が許容範囲外になったことを検知して送電コイル213への通電を中断させる。したがって、充電の途中で受電コイル128が送電コイル213に対向配置されなくなるという異常事態が発生してもフェイルセーフが機能する。  According to the present embodiment, even if thevibrator 116 vibrates during charging, the possibility that themobile device 100 moves outside themark 222 is extremely low. Even if theportable device 100 moves to the outside of themark 222, the power transmissionside control unit 210 detects that the amount of change in the impedance of thepower transmission coil 213 is outside the allowable range, and energizes thepower transmission coil 213. Interrupt. Therefore, even if an abnormal situation occurs in which thepower receiving coil 128 is not disposed opposite to thepower transmitting coil 213 during charging, the fail safe functions.

本実施形態の充電システム10では、シート部材221に熱可塑性ゴムを用いる構成であったが、本発明は熱可塑性ゴムに限定されない。シート部材221は、熱可塑性ゴムの他に熱可塑性エラストマーとしての熱可塑性ポリウレタン樹脂、一般には熱硬化しにくい組成のシリコーン樹脂、粘度調整剤としての可塑剤が添加されたゴム、樹脂(例えば塩化ビニルのような熱可塑性樹脂)といった加熱されると粘度が低下する材料であればよい。  In the charging system 10 of the present embodiment, the thermoplastic rubber is used for thesheet member 221, but the present invention is not limited to the thermoplastic rubber. Thesheet member 221 is made of a thermoplastic polyurethane resin as a thermoplastic elastomer in addition to a thermoplastic rubber, generally a silicone resin having a composition hard to be cured by heat, a rubber or a resin (for example, vinyl chloride) to which a plasticizer as a viscosity modifier is added. Any material can be used as long as its viscosity is reduced when heated.

また本発明では、図4に示すように、シート部材221は、携帯機器100が配置されたときに携帯機器100の重量によって重力方向に沈み込むように変形することが望ましい。このようにシート部材221が変形することによって、携帯機器100の周囲を囲む段差がシート部材221に形成される。この段差によって、携帯機器100の移動をさらに抑制することが可能となる。この段差の高さを十分に確保するため、シート部材221の厚さtは、携帯機器100の重量により重力方向に沈み込む深さΔtよりも十分厚いことが望ましい。また充電時の熱と、携帯機器100の質量、充電器200との接触面形状、接触面積とを考慮してシート部材221の厚さtや、粘度を設定すればよい。シート部材221の厚さtや、携帯機器100の沈み込み量が充分に大きくなるように構成すれば充電器200が傾いた状態、斜面に設置された場合にでも横滑りを防ぐこともできる。  In the present invention, as shown in FIG. 4, it is desirable that thesheet member 221 is deformed so as to sink in the direction of gravity due to the weight of theportable device 100 when theportable device 100 is arranged. As thesheet member 221 is deformed in this manner, a step around the periphery of theportable device 100 is formed in thesheet member 221. This step can further suppress the movement of themobile device 100. In order to sufficiently secure the height of the step, it is desirable that the thickness t of thesheet member 221 is sufficiently thicker than the depth Δt that sinks in the direction of gravity due to the weight of theportable device 100. In addition, the thickness t and the viscosity of thesheet member 221 may be set in consideration of the heat during charging, the mass of theportable device 100, the shape of the contact surface with thecharger 200, and the contact area. If the thickness t of thesheet member 221 and the sinking amount of theportable device 100 are configured to be sufficiently large, a side slip can be prevented even when thecharger 200 is inclined or installed on a slope.

本発明では、シート部材211は熱可塑性ゴムや、前述の材料に限定されない。ゴムのような弾性体だけでなく、加わる力に応じて変形し、力が解放されれば自然と元の形状へと復元するような粘弾性体、例えば熱硬化性ウレタン樹脂やメラミン樹脂のスポンジ状部材であったりしてもよい。熱に応じて粘度が低くなる材料である必要もない。すなわち、本発明のシート部材は、携帯機器と、前記携帯機器を非接触充電にて充電するための充電器と、の間に敷くシート部材であって、前記携帯機器が配置されたときに前記携帯機器の重量によって重力方向に沈み込むように変形する材料であってもよい。  In the present invention, thesheet member 211 is not limited to thermoplastic rubber or the aforementioned materials. Not only elastic bodies such as rubber, but also viscoelastic bodies that can be deformed according to the force applied and restore to their original shape when the force is released, such as a thermosetting urethane resin or melamine resin sponge It may be a shaped member. There is no need for the material to have a viscosity that decreases with heat. That is, the sheet member of the present invention is a sheet member laid between a portable device and a charger for charging the portable device by non-contact charging, and when the portable device is disposed, The material may be deformed so as to sink in the direction of gravity due to the weight of the portable device.

シート部材221が携帯機器100の重量に応じて変形すると、受電コイル128と送電コイル213との間の距離も変化する。そのため、携帯機器100を配置した場合と、重量が携帯機器100と異なる他の充電非対象の携帯機器、金属異物を配置した場合では、送電コイル213のインピーダンスの変化量が異なるため誤って送電されることを防ぐことも期待できる。しかしながら、本実施形態のように、送電コイル213のインピーダンスの変化量に基づいて充電対象物か否か判断する場合、携帯機器の重量の違いを考慮できないため判断を誤る可能性がある。そこで、本発明では、充電器200が携帯機器の識別子に基づいて充電対象物か否か判断することとしてもよい。具体的には、ステップS1において、通信回路127が、受電側制御部125の制御に基づいて、ROM11に予め格納されている携帯機器100の識別子を充電器200へ送信する。充電器200では、送電側制御部210が、識別子毎に予め対応付けられている許容範囲に基づいて充電対象物か否か判断する。これにより、携帯機器の重量に関わらず充電対象物か否か正しく判断することが可能となる。  When thesheet member 221 is deformed according to the weight of themobile device 100, the distance between thepower receiving coil 128 and thepower transmitting coil 213 also changes. Therefore, when theportable device 100 is arranged, and when another non-chargeable portable device or metal foreign object having a weight different from that of theportable device 100 is arranged, the amount of change in impedance of thepower transmission coil 213 is different, so that power is erroneously transmitted. It can also be expected to prevent this. However, as in this embodiment, when it is determined whether or not the charging target is based on the amount of change in the impedance of thepower transmission coil 213, the determination may be erroneous because the difference in the weight of the portable device cannot be taken into account. Therefore, in the present invention, it may be determined whether or not thecharger 200 is an object to be charged based on the identifier of the portable device. Specifically, in step S <b> 1, thecommunication circuit 127 transmits the identifier of theportable device 100 stored in advance in the ROM 11 to thecharger 200 based on the control of the power receivingside control unit 125. In thecharger 200, the power transmissionside control unit 210 determines whether or not it is a charging target object based on an allowable range associated in advance for each identifier. As a result, it is possible to correctly determine whether the object is a charging object regardless of the weight of the portable device.

本実施形態では、受電コイル128を受電部とし、送電コイル213を送電部とする磁界結合方式を例に説明したが、電界結合方式でも同様に行うことが可能である。電界結合方式の場合、携帯機器100には受電コイル128の代わりに受電電極が受電部として設けられ、充電器200には送電コイル213の代わりに送電電極が送電部として設けられる。  In the present embodiment, the magnetic field coupling method using thepower receiving coil 128 as the power receiving unit and thepower transmitting coil 213 as the power transmitting unit has been described as an example. However, the electric field coupling method can be similarly performed. In the case of the electric field coupling method, themobile device 100 is provided with a power receiving electrode as a power receiving unit instead of thepower receiving coil 128, and thecharger 200 is provided with a power transmitting electrode as a power transmitting unit instead of thepower transmitting coil 213.

本実施形態では、シート部材221の上面にマーク222を形成したが、ムービングコイル方式と呼ばれる、携帯機器100の受電コイル128の位置に合わせて充電器200側の送電コイル213が移動する方式や、電界結合方式のように位置ずれに対する充電効率が比較的落ちない方式ではマークは不要である。  In the present embodiment, themark 222 is formed on the upper surface of thesheet member 221, but a method called a moving coil method in which thepower transmission coil 213 on thecharger 200 side moves according to the position of thepower receiving coil 128 of themobile device 100, Marks are not necessary for a method in which the charging efficiency with respect to displacement is relatively low, such as the electric field coupling method.

本実施形態では、インピーダンス値を測定する方法や、送電コイル、受電コイル間で通信する方法にて充電制御する例で説明したが、別の方法や、別の通信手段を用いて行ってもよいので、本充電制御に限定されない。充電時に発熱するような非接触充電であればよい。  In the present embodiment, the charging control is described by the method of measuring the impedance value and the method of communicating between the power transmission coil and the power receiving coil, but may be performed using another method or another communication means. Therefore, it is not limited to this charge control. Any non-contact charging that generates heat during charging may be used.
