Abstract

A housing (31) has a surface. A coil (34) is disposed at the back of a part of the area on the surface. The expected range of the part of the area is a part or whole of an area (AR). The part of the area is processed so that a metal seal tends not to bond thereto. Any one of the following processing methods may be employed: A. The part of the area is formed as a projection (31a). B. The part of the area is rough and not smooth. C. The part of the area is raised with respect to the surrounding area. D. The part of the area is depressed with respect to the surrounding area. These processing methods facilitate the peeling off of a metal seal and thus prevent dielectric heating.

Description

無接点充電される装置Non-contact charged device
　本発明が関係するのは、無接点（ワイヤレス）充電される装置である。より詳しくは、スマートフォン、携帯電話やポータブルナビゲーション装置等である。 The present invention is related to a non-contact (wireless) charging device. More specifically, they are smartphones, mobile phones, portable navigation devices, and the like.
　近年流通しているのは、無接点充電される装置である。この無接点充電システムを構成するのは、端末及び充電装置である。端末を構成するのは、充電コイル及び筐体である。充電コイルの機能は、起電である。起電の原理は、電磁誘導である。充電コイルの設置場所は、筐体内側である。筐体の背面が有するのは、凹部である。凹部の機能は、後述する位置決めである。凹部の位置は、充電コイルの中心の同軸上である。他方、充電装置を構成するのは、電力供給コイル及び装置本体である。電力供給コイルの機能は、励磁である。励磁の原理は、電磁誘導である。電力供給コイルが設けられているのは、装置本体内である。装置本体の表面が有するのは、凸部である。凸部の位置は、電力供給コイルの中心の同軸上である。凸部の機能は、位置決めである。つまり、凸部の挿入先を凹部とすることで、電力供給コイルの位置が充電コイルの中心の同軸上となる。その結果、充電効率は向上する（例えば、特許文献１および特許文献参照）。 In recent years, non-contact charging devices are in circulation. The contactless charging system is composed of a terminal and a charging device. The terminal is composed of a charging coil and a casing. The function of the charging coil is electromotive force. The principle of electromotive force is electromagnetic induction. The charging coil is installed inside the housing. The back surface of the housing has a recess. The function of the recess is positioning described later. The position of the recess is coaxial with the center of the charging coil. On the other hand, the power supply coil and the device body constitute the charging device. The function of the power supply coil is excitation. The principle of excitation is electromagnetic induction. The power supply coil is provided in the apparatus main body. The surface of the apparatus main body has a convex portion. The position of the convex portion is coaxial with the center of the power supply coil. The function of the convex portion is positioning. That is, by making the insertion destination of the convex portion a concave portion, the position of the power supply coil is coaxial with the center of the charging coil. As a result, the charging efficiency is improved (see, for example, Patent Document 1 and Patent Document).
　従前から流通しているのは、金属性の装飾シール（以下、メタルシールという）である。例示すると、金属板であって粘着材が付されたものやアルミ性シール等である。一般的に、メタルシールが貼られるのは、端末の背面である。 A metal decorative seal (hereinafter referred to as a metal seal) has been in circulation for a long time. Illustrative examples include a metal plate to which an adhesive material is attached and an aluminum seal. Generally, the metal seal is pasted on the back of the terminal.
　当該装飾された端末が無接点充電される場合、メタルシールが発熱する。その原理は、いわゆる誘電加熱である。メタルシールが達する温度は、約１８０度である。その結果、携帯装置又は充電装置は変形する。 メ タ ル When the decorated terminal is contactlessly charged, the metal seal generates heat. The principle is so-called dielectric heating. The temperature reached by the metal seal is about 180 degrees. As a result, the portable device or the charging device is deformed.
　そこで必要なのは、誘電加熱を防ぐための技術である。この充電装置を構成するのは、検出回路及び制御回路である。検出回路の機能は、金属異物の検出である。制御回路の機能は、充電の抑制である。充電が抑制されるのは、金属異物が検出された時である（例えば、特許文献３および特許文献４参照）。 Therefore, what is needed is a technique to prevent dielectric heating. The charging device is configured by a detection circuit and a control circuit. The function of the detection circuit is to detect metallic foreign matter. The function of the control circuit is to suppress charging. Charging is suppressed when a metallic foreign object is detected (see, for example, Patent Document 3 and Patent Document 4).
　前述の公知技術において重要なのは、如何にして検出精度を向上させるかである。しかし、仮に検出精度が向上しても、困難なのは、検出漏れをゼロにすることである。しかも、メタルシールの温度が約１８０度になるまでに要する時間は、約３秒程度である。つまり、誘電加熱を防ぐために大切なのは、如何にしてメタルシールを貼付させないかである。 What is important in the above-mentioned known technology is how to improve the detection accuracy. However, even if the detection accuracy is improved, it is difficult to make the detection omission zero. Moreover, the time required for the temperature of the metal seal to reach about 180 degrees is about 3 seconds. In other words, what is important for preventing dielectric heating is how to prevent the metal seal from being applied.

　本発明に係る無接点充電される装置を構成するのは、コイル及び筐体である。筐体表面の一部領域は、その背後にコイルが配置されている。当該一部領域又はその近傍は、加工されており、それによって、メタルシールが貼り難くなっている。加工が含む概念は、成形及び取付けである。加工方法を決定する基準は、以下で掲げる原理の少なくとも１つである。 It is a coil and a casing that constitute a non-contact charging device according to the present invention. A coil is disposed behind a part of the surface of the housing. The partial region or the vicinity thereof is processed so that it is difficult to attach a metal seal. The concepts involved in processing are molding and attachment. The criterion for determining the processing method is at least one of the following principles.
　メタルシールを貼り難くする条件は、接着力が不足することである。ここで、接着とは、メタルシール及び筐体を互いに引き付けることである（分子間力）。接触面積が少ないので、接着力は低くなる。 The condition that makes it difficult to apply the metal seal is that the adhesive strength is insufficient. Here, adhesion means to attract the metal seal and the housing to each other (intermolecular force). Since the contact area is small, the adhesive force is low.
　メタルシールを貼り難くする条件は、接着力より復元力が大きいことである。ここで、復元とは、メタルシールの状態が曲がった状態から平らな状態になることである。 The condition that makes it difficult to apply the metal seal is that the restoring force is greater than the adhesive strength. Here, restoration means that the state of the metal seal is changed from a bent state to a flat state.
　これらの原理の下で採用されるのは、一部領域を凹凸させること、粗く滑らかでなくすること、一部領域を曲げることや突起させること等である。 ¡Under these principles, it is adopted to make a partial region uneven, to make it rough and not smooth, to bend or project a partial region, etc.
　以上の説明が前提とするのは、無接点充電の原理が電磁誘導方式である場合であるが、電波方式や電磁界共鳴方式等の他の方式も本発明が排除するものではない。 The above explanation assumes that the principle of contactless charging is an electromagnetic induction method, but other methods such as a radio wave method and an electromagnetic resonance method are not excluded by the present invention.
　筐体表面の一部領域は、その背後にコイルが配置されている。当該一部領域は、加工されており、それによって、メタルシールが貼り難くなっている。つまり、メタルシールが殆ど誘電加熱されないので、筐体の変形を防ぐことができる。 A coil is placed behind a part of the housing surface. The said partial area | region is processed and it becomes difficult to stick a metal seal by it. That is, since the metal seal is hardly subjected to dielectric heating, deformation of the housing can be prevented.

These technical contents are incorporated as appropriate and are a part of the present specification.

FIG. 3 is a rear view of the information processing apparatus 30 according to the present embodiment.

Its function is electromotive force. The condition for generating electromotive force is that the magnetic force H penetrates. A destination to which the coil 34 is connected is a battery 33. That is, when the magnetic force H penetrates, the battery 33 is charged. The coil 34 is disposed inside the housing 31. The area AR including the coil 34 will be described with reference to FIGS. 4A to 4D.
　その他付随的な技術の内容を開示するのは、特開２００８－１４１９４０号公報及び特開２００８－２３６８８６号公報である。これらの技術内容は、適宜取込まれ、本願明細書の一部とする。 The contents of other ancillary technologies are disclosed in Japanese Unexamined Patent Application Publication Nos. 2008-141940 and 2008-236886. These technical contents are incorporated as appropriate and are a part of the present specification.
　図４Ａ～図４Ｄは、本実施の形態に係る情報処理装置の図２における４－４断面図である。筐体３１が有するのは、表面である。表面の一部領域は、その背後にコイル３４が配置されている。本実施の形態において、当該一部領域の想定範囲は、領域ＡＲの一部又は全部である。当該一部領域は、加工されており、それによって、メタルシール（図示せず）が貼り難くなっている。加工方法は、次のとおりである。 4A to 4D are cross-sectional views taken along the line 4-4 in FIG. 2 of the information processing apparatus according to the present embodiment. The housing 31 has a surface. The coil 34 is arranged behind the partial region of the surface. In the present embodiment, the assumed range of the partial area is a part or all of the area AR. The said partial area | region is processed and it becomes difficult to stick a metal seal (not shown) by it. The processing method is as follows.
　図４Ａが示すのは、当該一部領域が突起しているものである。そのような突起３１ａを設けるための好ましい方法は、樹脂成形である。もちろん、突起３１ａは、別途取り付けられても良い。突起３１ａは、凹凸の一種ともいいうる。当該実施の形態では、突起３１ａが支点となって、貼られたメタルシールは撓む。撓んだメタルシールは、復元する。また、接着面積が小さいので、接着力が弱まり易い。つまり、メタルシールは、剥がれやすくなる（貼り難い）ので、誘電加熱されない。 FIG. 4A shows that the partial area protrudes. A preferred method for providing such a protrusion 31a is resin molding. Of course, the protrusion 31a may be attached separately. The protrusion 31a can also be referred to as a kind of unevenness. In the said embodiment, the protrusion 31a becomes a fulcrum, and the stuck metal seal bends. The bent metal seal is restored. Moreover, since the adhesion area is small, the adhesion force tends to be weakened. That is, since the metal seal is easily peeled off (it is difficult to stick), it is not dielectrically heated.
　図４Ｂが示すのは、当該一部領域が粗く、滑らかでないものである。そのような粗面３１ｂを設けるための好ましい方法は、いわゆるエンボス加工である。もちろん、粗目の樹脂を貼り付ける方法も妨げられない。当該実施の形態では、粗面３１ｂとメタルシールとの接着面積は、相対的に小さい。その比較基準は、平滑面とメタルシールとの接着面積である。つまり、メタルシールは、剥がれやすくなる（貼り難い）ので、誘電加熱されない。 FIG. 4B shows that the partial area is rough and not smooth. A preferred method for providing such a rough surface 31b is so-called embossing. Of course, the method of attaching a coarse resin is not hindered. In the present embodiment, the bonding area between the rough surface 31b and the metal seal is relatively small. The comparison standard is an adhesion area between the smooth surface and the metal seal. That is, since the metal seal is easily peeled off (it is difficult to stick), it is not dielectrically heated.
　図４Ｃが示すのは、当該一部領域を曲げたものである。当該実施の形態において、当該一部領域は、その周囲よりも盛り上がっている。そのような***部３１ｃを設けるための好ましい方法は、樹脂成形である。***部３１ｃが支点となって、貼られたメタルシールは撓む。撓んだメタルシールは、復元する。また、接着面積が小さいので、接着力が弱まり易い。つまり、メタルシールは、剥がれやすくなる（貼り難い）ので、誘電加熱されない。 FIG. 4C shows that the partial area is bent. In the embodiment, the partial area is raised more than the surrounding area. A preferred method for providing such a raised portion 31c is resin molding. The protruding metal portion 31c serves as a fulcrum, and the attached metal seal bends. The bent metal seal is restored. Moreover, since the adhesion area is small, the adhesion force tends to be weakened. That is, since the metal seal is easily peeled off (it is difficult to stick), it is not dielectrically heated.
　図４Ｄが示すのは、当該一部領域を曲げたものである。当該実施の形態において、当該一部領域は、その周囲よりも窪んでいる。そのような窪み３１ｄを設けるための好ましい方法は、樹脂成形である。当該実施の形態では、筐体３１の背面とメタルシールとの接着面積は、相対的に小さい。その比較基準は、窪んでいない場合の接着面積である。つまり、メタルシールは、剥がれやすくなる（貼り難い）ので、誘電加熱されない。 FIG. 4D shows a bent portion of the partial area. In the embodiment, the partial region is recessed from the periphery. A preferred method for providing such a recess 31d is resin molding. In the embodiment, the adhesion area between the back surface of the housing 31 and the metal seal is relatively small. The comparison standard is an adhesion area when not recessed. That is, since the metal seal is easily peeled off (it is difficult to stick), it is not dielectrically heated.
