Description

本発明は、バッテリを収容可能なバッテリケースに関し、詳しくは、そのバッテリケースの周囲にＲＦＩＤ（無線周波数識別：Radio Frequency Identification）用アンテナを配設した場合にそのアンテナの受信強度を高めることのできるバッテリケース、及びそのバッテリケースが装着される電子機器に関する。   The present invention relates to a battery case that can accommodate a battery. Specifically, when an RFID (Radio Frequency Identification) antenna is provided around the battery case, the reception strength of the antenna can be increased. The present invention relates to a battery case and an electronic device to which the battery case is attached.

近年、ＲＦＩＤによって電波・電磁波の送受信を行うアンテナ送受信部は、携帯電話機等の各種電子機器にも装着されるようになった。そこで、アンテナと、シート状の磁性体と、シート状の導体とを順に積層することが提案されている（例えば、特許文献１参照）。このように、アンテナとシート状の導体との間にシート状の磁性体を配設することにより、受信強度を高めることができる。
特開２００５−１２２５９５号公報 In recent years, antenna transmission / reception units that transmit and receive radio waves and electromagnetic waves using RFID have come to be attached to various electronic devices such as mobile phones. Therefore, it has been proposed to sequentially stack an antenna, a sheet-like magnetic body, and a sheet-like conductor (for example, see Patent Document 1). As described above, the reception strength can be increased by disposing the sheet-like magnetic body between the antenna and the sheet-like conductor.
JP 2005-122595 A

ところが、アンテナとシート状の導体との間にシート状の磁性体を配設する作業は作業性が悪かった。そこで、本発明は、アンテナと導体との間に磁性体を配設した構造を、容易に作成することのできるバッテリケース、及びそのバッテリケースが装着される電子機器の提供を目的としてなされた。   However, the work of disposing a sheet-like magnetic body between the antenna and the sheet-like conductor has poor workability. In view of the above, an object of the present invention is to provide a battery case in which a structure in which a magnetic body is disposed between an antenna and a conductor can be easily created, and an electronic device to which the battery case is attached.

上記目的を達するためになされた本発明は、バッテリを収容可能な形状に樹脂にて成形されたバッテリケースであって、上記樹脂に磁性フィラーが充填されたことを特徴としている。   The present invention made to achieve the above object is a battery case formed of a resin in a shape capable of accommodating a battery, wherein the resin is filled with a magnetic filler.

このように構成された本発明のバッテリケースは、そのバッテリケースを構成する樹脂に磁性フィラーが充填されている。このため、そのバッテリケースの表面にアンテナを配設するだけで、そのアンテナ，磁性体としての磁性フィラー，及び導体としてのバッテリが順次積層された構造を容易に作成することができる。従って、アンテナと導体との間に磁性体を配設してそのアンテナの受信強度を高めることが、容易に良好な作業性で実行できる。   In the battery case of the present invention configured as described above, the resin constituting the battery case is filled with a magnetic filler. For this reason, the structure which laminated | stacked the antenna, the magnetic filler as a magnetic body, and the battery as a conductor sequentially can be created easily only by arrange | positioning an antenna on the surface of the battery case. Accordingly, it is possible to easily execute the magnetic material between the antenna and the conductor to increase the receiving strength of the antenna with good workability.

また、バッテリは、導体として設置位置・形状・導電性のバラツキが少ないことに、本願出願人は着目した。そして、上記のようにバッテリを覆っている樹脂に磁性フィラーを入れることにより、バッテリに使われている導体の影響を効率よく減少させ、アンテナを近くに設置することが可能となる。このため、アンテナの受信強度を高めるための上記構成を省スペース化することができる。   Further, the applicant of the present application paid attention to the fact that the battery has less variation in the installation position, shape, and conductivity as a conductor. Then, by inserting a magnetic filler into the resin covering the battery as described above, the influence of the conductor used in the battery can be efficiently reduced, and the antenna can be installed nearby. For this reason, the said structure for raising the receiving strength of an antenna can be saved.

なお、本発明は、バッテリケースの形状やアンテナの形状を特に限定するものではないが、バッテリケースが扁平な板状に構成され、周囲にＲＦＩＤ用アンテナを環状に配設可能であってもよい。   In the present invention, the shape of the battery case and the shape of the antenna are not particularly limited, but the battery case may be formed in a flat plate shape, and the RFID antenna may be annularly disposed around the battery case. .

従来はＦＰＣや基板のアンテナを使用していたが、磁性体や導体が設置してある面側は電磁界強度が弱く通信ができなかった。このため、片面だけが通信に利用可能であるため利便性が悪かった。これに対して、本発明では、アンテナをバッテリケースの表面に配設する構成を採用したことにより、上記のようにアンテナを環状に配設することが可能となり、この場合、従来は困難であった表裏の２方向に通信を行うことができる。また、この場合、そのバッテリケースは、ＲＦＩＤ用アンテナを使用する電子機器に装着可能で、その電子機器に電力を供給するバッテリが収容可能であってもよい。   Conventionally, an FPC or a substrate antenna has been used, but the surface side on which the magnetic body and the conductor are installed has a weak electromagnetic field strength and cannot communicate. For this reason, since only one side can be used for communication, it is not convenient. On the other hand, in the present invention, since the antenna is arranged on the surface of the battery case, the antenna can be arranged in an annular shape as described above. Communication can be performed in two directions. In this case, the battery case may be attached to an electronic device using an RFID antenna, and a battery that supplies power to the electronic device may be accommodated.

また、本発明のバッテリケースは、扁平な板状に構成され、表裏両面にシート状のＲＦＩＤ用アンテナが設けられてもよい。この場合も、従来は困難であった表裏の２方向に通信を行うことができる。   Moreover, the battery case of this invention may be comprised by the flat plate shape, and the sheet-like RFID antenna may be provided in both front and back. Also in this case, communication can be performed in two directions, which are difficult in the past.

また、本発明の電子機器は、上記いずれかの発明のバッテリケースを収容可能な収容部を有し、該収容部の外周または内周に、ＲＦＩＤ用アンテナが環状に配設されたことを特徴としている。   In addition, an electronic device according to the present invention has a housing portion that can accommodate the battery case according to any one of the above inventions, and an RFID antenna is annularly disposed on an outer periphery or an inner periphery of the housing portion. It is said.

このように構成された本発明の電子機器では、収容部の外周または内周にＲＦＩＤ用アンテナが環状に配設されている。このため、その収容部に上記いずれかの発明のバッテリケースを収容するだけで、ＲＦＩＤ用アンテナ，磁性体としての磁性フィラー，及び導体としてのバッテリが順次積層された構造を容易に作成することができる。従って、アンテナと導体との間に磁性体を配設してそのアンテナの受信強度を高めることが、容易に良好な作業性で実行できる。また、ＲＦＩＤ用アンテナは環状に配設されているため、前述のように表裏の２方向に通信を行うことができ、携帯電話機などの携帯型の電子機器に適用するのに一層好適である。更に、本発明では、バッテリの周囲にアンテナを配設しているため、バッテリに使われている導体の影響を効率よく減少させ、アンテナの受信強度を高めるための上記構成を省スペース化することができる。   In the electronic apparatus of the present invention configured as described above, the RFID antenna is annularly arranged on the outer periphery or inner periphery of the housing portion. For this reason, it is possible to easily create a structure in which an RFID antenna, a magnetic filler as a magnetic body, and a battery as a conductor are sequentially stacked by simply housing the battery case of any of the above inventions in the housing portion. it can. Accordingly, it is possible to easily execute the magnetic material between the antenna and the conductor to increase the receiving strength of the antenna with good workability. In addition, since the RFID antenna is arranged in a ring shape, communication can be performed in two directions, as described above, and it is more suitable for application to a portable electronic device such as a cellular phone. Furthermore, in the present invention, since the antenna is disposed around the battery, the above-described configuration for efficiently reducing the influence of the conductor used in the battery and increasing the reception strength of the antenna can be saved. Can do.

また、本発明の電子機器は、更に、上記ＲＦＩＤ用アンテナが、上記環状形状の表裏両方向に通信可能であってもよい。この場合、従来は困難であった電子機器の表裏の２方向への通信を行うことができる。   In the electronic device of the present invention, the RFID antenna may be capable of communicating in both the front and back directions of the annular shape. In this case, it is possible to perform communication in two directions on the front and back of the electronic device, which has been difficult in the past.

FIG. 1 is a perspective view showing a configuration of a mobile phone 1 as an electronic apparatus to which the present invention is applied. The mobile phone 1 is a so-called foldable mobile phone in which a first housing 1a and a second housing 1b are foldably connected via a hinge portion 1c. In FIG. 1, a panel having a plurality of key buttons indicating numbers, letters, symbols, and the like is omitted from the second housing 1 b and its internal configuration is illustrated.

図１に示すように、第１筐体１ａの内側面（折り畳み時に第２筐体１ｂと対向する面）には、液晶表示装置からなる表示部２と、スピーカ３とが設けられている。第２筐体１ｂの内側面には、図示省略した上記キーボタンが設けられている。   As shown in FIG. 1, a display unit 2 made of a liquid crystal display device and a speaker 3 are provided on the inner side surface of the first housing 1a (the surface facing the second housing 1b when folded). The key buttons (not shown) are provided on the inner side surface of the second housing 1b.

更に、第２筐体１ｂの内部には、内側面に一部露出するマイク５と、ＣＰＵ等の各種素子をプリント配線基板上に配設してなる制御部６と、バッテリケース１０を収容可能な収容部７と、ＲＦＩＤ用アンテナ９とが設けられている。図１に示すように、バッテリケース１０は矩形の平板状に構成されている。第２筐体１ｂの外側面は、カバー１ｄが着脱可能に構成され、収容部７は、カバー１ｄを外したときに外側面側からバッテリケース１０を収容可能な矩形の凹部（第２筐体１ｂの内部から見れば凸部）として構成されている。ＲＦＩＤ用アンテナ９は、その収容部７の外周に、矩形の環状に配設されている。図２は、このＲＦＩＤ用アンテナ９の構成を詳細に表す斜視図である。図２に示すように、ＲＦＩＤ用アンテナ９は、収容部７の外周にコイル状に幾重にも巻回されている。   Further, inside the second housing 1b, a microphone 5 partially exposed on the inner surface, a control unit 6 in which various elements such as a CPU are disposed on a printed wiring board, and a battery case 10 can be accommodated. An accommodating portion 7 and an RFID antenna 9 are provided. As shown in FIG. 1, the battery case 10 is configured in a rectangular flat plate shape. The outer surface of the second housing 1b is configured such that the cover 1d is detachable, and the housing portion 7 is a rectangular recess (second housing) that can house the battery case 10 from the outer surface side when the cover 1d is removed. If it sees from the inside of 1b, it is comprised as a convex part). The RFID antenna 9 is arranged in a rectangular ring around the outer periphery of the housing portion 7. FIG. 2 is a perspective view showing the configuration of the RFID antenna 9 in detail. As shown in FIG. 2, the RFID antenna 9 is wound around the outer periphery of the accommodating portion 7 in a coil shape.

図３の断面図に示すように、バッテリケース１０は、携帯電話機１に電力を供給する二次電池としてのバッテリ１１を外周全体から収容するように樹脂にて成形されており、その樹脂には磁性フィラーが充填されている。ここで、そのバッテリケース１０の製造方法について、一例を挙げて説明する。バッテリケース１０は、例えば次のような工程を経て製造することができる。
（１）磁性フィラーの作成工程
Ｓｉ：８〜２０ｗｔ％、Ｃｒ：０．５〜１０ｗｔ％、残部Ｆｅ及び不純物（微量添加物を含む）からなる合金を作成し、それに粉砕及び扁平化処理を施すことにより、密度が６〜９ｇ／ｃｍ3 、粒度分布がＤ５０で１０〜３０μｍ、アスペクト比が３以上の扁平粒子を磁性フィラーとして作成する。なお、磁性フィラーとしては、このようなＦｅ−Ｓｉ−Ｃｒ系の他、Ｆｅ−Ｓｉ系、Ｆｅ−Ｓｉ−Ａｌ系、フェライト、アモルファス、鉄基ナノ結晶体など、各種磁性フィラーを使用することができる。
（２）ペレット製造工程
この磁性フィラーを、ナイロン、ＰＰＳ（ポリフェニレンサルファイド）、ＡＢＳ（アクリロニトリル・ブタジエン・スチレン樹脂）、ＰＣ（ポリカーボネート）、エラストマなどの樹脂と混合し、溶融させて柱状に押し出す。その柱状に押し出された材料を、硬化後切断することにより、ペレットを製造する。
（３）成形工程
上記のように製造されたペレットを、射出成形することにより、バッテリケース１０を製造する。なお、成形方法として、射出成形の他、塩素化ポリエチレン、アクリル、ウレタン、ＮＢＲ（ニトリルゴム）、エポキシ、ホットメルト材などの樹脂を用いてコンプレッション成形やトランスファ成形等の成形方法も用いることができる。また、バッテリ１１は、バッテリケース１０の成形時にそのバッテリケース１０に一体に収容されるようにしてもよく、バッテリケース１０の成形後に収容してもよい。 As shown in the cross-sectional view of FIG. 3, the battery case 10 is molded from a resin so as to accommodate a battery 11 as a secondary battery that supplies power to the mobile phone 1 from the entire outer periphery. Filled with magnetic filler. Here, a method for manufacturing the battery case 10 will be described with an example. The battery case 10 can be manufactured through the following processes, for example.
(1) Magnetic filler production process Si: 8-20 wt%, Cr: 0.5-10 wt%, an alloy composed of the balance Fe and impurities (including a trace additive) is produced, and pulverized and flattened. Thus, flat particles having a density of 6 to 9 g / cm 3 , a particle size distribution of D50 of 10 to 30 μm, and an aspect ratio of 3 or more are prepared as magnetic fillers. In addition to the Fe-Si-Cr type, various magnetic fillers such as Fe-Si type, Fe-Si-Al type, ferrite, amorphous, and iron-based nanocrystal may be used as the magnetic filler. it can.
(2) Pellet manufacturing process This magnetic filler is mixed with nylon, PPS (polyphenylene sulfide), ABS (acrylonitrile / butadiene / styrene resin), PC (polycarbonate), elastomer, or other resin, melted, and extruded into a columnar shape. The material extruded into the columnar shape is cut after curing to produce pellets.
(3) Molding process The battery case 10 is manufactured by injection-molding the pellet manufactured as described above. As a molding method, in addition to injection molding, a molding method such as compression molding or transfer molding using a resin such as chlorinated polyethylene, acrylic, urethane, NBR (nitrile rubber), epoxy, or hot melt material can be used. . Further, the battery 11 may be accommodated integrally in the battery case 10 when the battery case 10 is molded, or may be accommodated after the battery case 10 is molded.

このようにして、磁性フィラーが充填された樹脂によって成形されたバッテリケース１０を得ることができる。なお、上記製造方法は一例であり、他にも種々の製造方法が考えられる。また、上記磁性フィラーの適切な充填量は３０〜６０ｖｏｌ％である。   In this way, the battery case 10 molded from the resin filled with the magnetic filler can be obtained. The above manufacturing method is an example, and various other manufacturing methods are conceivable. Moreover, the suitable filling amount of the said magnetic filler is 30-60 vol%.

このように構成された携帯電話機１では、収容部７の外周にＲＦＩＤ用アンテナ９が配設されており、バッテリケース１０を構成する樹脂には磁性フィラーが充填されている。このため、収容部７にバッテリケース１０を収容するだけで、ＲＦＩＤ用アンテナ９，磁性体としての磁性フィラー，及び導体としてのバッテリ１１が順次積層された構造を作成することができる。従って、ＲＦＩＤ用アンテナ９と導体としてのバッテリ１１との間に磁性体を配設してそのＲＦＩＤ用アンテナ９の受信強度を高めることが、極めて容易に極めて良好な作業性で実行できる。   In the mobile phone 1 configured as described above, the RFID antenna 9 is disposed on the outer periphery of the housing portion 7, and the resin constituting the battery case 10 is filled with a magnetic filler. For this reason, a structure in which the RFID antenna 9, the magnetic filler as the magnetic material, and the battery 11 as the conductor are sequentially stacked can be created simply by housing the battery case 10 in the housing portion 7. Therefore, it is extremely easy to perform a very good workability by arranging a magnetic body between the RFID antenna 9 and the battery 11 as a conductor to increase the reception strength of the RFID antenna 9.

すなわち、バッテリケース１０が一般の樹脂で構成されていると、収容部７の外周に磁性シートを貼着してからＲＦＩＤ用アンテナ９を配設する作業が必要となるが、本実施の形態では、バッテリケース１０が磁性フィラーを充填した樹脂で構成されているため、収容部７にバッテリケース１０を収容するだけでよいのである。   That is, when the battery case 10 is made of a general resin, it is necessary to dispose the RFID antenna 9 after attaching a magnetic sheet to the outer periphery of the housing portion 7. Since the battery case 10 is made of resin filled with a magnetic filler, the battery case 10 need only be accommodated in the accommodating portion 7.

また、バッテリ１１は、導体として設置位置・形状・導電性のバラツキが少ないため、上記のようにバッテリケース１０を構成する樹脂に磁性フィラーを入れることにより、バッテリ１１に使われている導体の影響を効率よく減少させることができる。更に、上記のようにＲＦＩＤ用アンテナ９を環状に配設することにより、従来は困難であった表裏の２方向に通信を行うことが可能となり、携帯電話機１の方向を気にせずに通信を行うことができる。更に、携帯電話機１では、バッテリ１１を導体として利用しているため、導体を別途設ける場合に比べ、ＲＦＩＤ用アンテナ９の受信強度を高めるための上記構成を省スペース化して、一層の小型化を図ることができる。   In addition, since the battery 11 has less variation in the installation position, shape, and conductivity as a conductor, the influence of the conductor used in the battery 11 can be obtained by adding a magnetic filler to the resin constituting the battery case 10 as described above. Can be reduced efficiently. Further, by arranging the RFID antenna 9 in an annular shape as described above, it becomes possible to perform communication in two directions, which was difficult in the past, and communication can be performed without worrying about the direction of the mobile phone 1. It can be carried out. Furthermore, since the mobile phone 1 uses the battery 11 as a conductor, the above-described configuration for increasing the reception strength of the RFID antenna 9 can be saved and further miniaturized compared to the case where a conductor is provided separately. Can be planned.

なお、本発明は上記実施の形態になんら限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の形態で実施することができる。例えば、上記実施の形態では、ＲＦＩＤ用アンテナ９を収容部７の外周に設けているが、ＲＦＩＤ用アンテナ９は、収容部７の内周に設けてもよく、必要に応じて収容部７の外周と内周との両方に設けてもよい。   In addition, this invention is not limited to the said embodiment at all, It can implement with a various form in the range which does not deviate from the summary of this invention. For example, in the above embodiment, the RFID antenna 9 is provided on the outer periphery of the housing portion 7, but the RFID antenna 9 may be provided on the inner periphery of the housing portion 7, You may provide in both an outer periphery and an inner periphery.

更に、ＲＦＩＤ用アンテナはバッテリケース１０の外周に直接設けてもよい。図４（Ａ）は、バッテリケース１０の外周に、上記実施の形態と同様のＲＦＩＤ用アンテナ９を直接設けた例を表す斜視図であり、図４（Ｂ）はそのＡ-Ａ線断面図である。この場合、バッテリケース１０の交換時にはＲＦＩＤ用アンテナ９も交換され、携帯電話機１はＲＦＩＤ用アンテナ９を備えていなくてもよい。なお、この場合、ＲＦＩＤ用アンテナ９と携帯電話機１の制御部６とは、周知のコネクタ等を介して接続される。   Further, the RFID antenna may be provided directly on the outer periphery of the battery case 10. 4A is a perspective view showing an example in which the same RFID antenna 9 as that of the above embodiment is directly provided on the outer periphery of the battery case 10, and FIG. 4B is a cross-sectional view taken along the line AA in FIG. It is. In this case, when the battery case 10 is replaced, the RFID antenna 9 is also replaced, and the mobile phone 1 may not include the RFID antenna 9. In this case, the RFID antenna 9 and the control unit 6 of the mobile phone 1 are connected via a known connector or the like.

また、ＲＦＩＤ用アンテナとして従来のシート状のものを使用し、収容部７の表面（図１における上側面）に設けてもよい。更に、図５に示す例のように、シート状のＲＦＩＤ用アンテナ９９をバッテリケース１０の表裏面に設けてもよい。なお、図５（Ａ）はこの例のバッテリケース１０の構成を表す斜視図であり、図５（Ｂ）はその平面図、図５（Ｃ）はそのＢ−Ｂ線断面図である。図５（Ａ），（Ｂ）に示すように、ＲＦＩＤ用アンテナ９９は、扁平な渦巻状に構成されている。このようなＲＦＩＤ用アンテナ９９をバッテリケース１０の表裏面に設ければ、上記実施の形態と同様に、表裏の２方向に通信を行うことが可能となり、携帯電話機１の方向を気にせずに通信を行うことができる。   Further, a conventional sheet-like antenna may be used as the RFID antenna, and may be provided on the surface (upper side surface in FIG. 1) of the accommodating portion 7. Furthermore, a sheet-like RFID antenna 99 may be provided on the front and back surfaces of the battery case 10 as in the example shown in FIG. 5A is a perspective view showing the configuration of the battery case 10 of this example, FIG. 5B is a plan view thereof, and FIG. 5C is a sectional view taken along the line BB of FIG. As shown in FIGS. 5A and 5B, the RFID antenna 99 is formed in a flat spiral shape. If such an RFID antenna 99 is provided on the front and back surfaces of the battery case 10, communication can be performed in two directions on the front and back sides as in the above-described embodiment, and the direction of the mobile phone 1 is not concerned. Communication can be performed.

更に、バッテリ及びバッテリケースの形状としては、上記以外にも種々の形状が考えられ、本発明は携帯電話機以外の電子機器にも応用することができる。例えば、ＰＤＡ，デジタルカメラなど、バッテリを搭載する電子機器であれば種々の電子機器に応用可能である。   Further, various shapes other than the above are conceivable as the shape of the battery and the battery case, and the present invention can be applied to electronic devices other than the mobile phone. For example, any electronic device equipped with a battery, such as a PDA or a digital camera, can be applied to various electronic devices.
