Description

本発明は、例えば、複数個のソレノイドコイルで構成する発電コイルの中を、長さ方向に着磁された複数個の磁石を含む可動磁石が振動することにより発電を行う振動型電磁発電機に関する。   The present invention relates to a vibration type electromagnetic generator that generates power when a movable magnet including a plurality of magnets magnetized in a length direction vibrates in a power generation coil composed of a plurality of solenoid coils, for example. .

近年、携帯電話やゲーム機などの携帯電子機器の普及が進み、これらに内蔵されている２次電池の量がますます多くなってきている。また、無線技術の発展にともない、微小電力で信号を送受するＲＦＩＤ（Radio Frequency IDentification）の応用が拡がっている。特に電源を有するアクティブＲＦＩＤは、数百メートル以上の通信も可能である。このため、牧場の牛や馬などの健康管理や、子供達の登下校時の安全管理等への応用に期待が高まっている。   In recent years, portable electronic devices such as mobile phones and game machines have been widely used, and the amount of secondary batteries incorporated therein has been increasing. In addition, with the development of wireless technology, the application of RFID (Radio Frequency IDentification) that transmits and receives signals with minute power is expanding. In particular, an active RFID having a power source can communicate over several hundred meters. For this reason, it is expected to be applied to health management of cattle and horses in the ranch and safety management when children go to school.

一方、地球環境の維持改善のため、できるだけ環境負荷の少ない電池の研究開発も活発に行われている。その中で、通常無意識かつ無駄に消費されているエネルギーを電気エネルギーに変換して、充電し、この電気エネルギーを携帯機器などの電源として利用することが広く考えられている。   On the other hand, in order to maintain and improve the global environment, research and development of batteries with as little environmental impact as possible are being actively conducted. Among them, it is widely considered that energy that is normally unconsciously and wastefully consumed is converted into electric energy and charged, and this electric energy is used as a power source for a portable device or the like.

特許文献１には、外部から加わる振動によって発電する振動型電磁発電機について開示されている。ここで、図１０を参照して、振動型電磁発電機１００の構成例について説明する。振動型電磁発電機１００は、中空のパイプ１０５と、パイプ１０５に巻回された２個のソレノイドコイル１０４ａ，１０４ｂと、パイプ１０５の内部を移動可能な可動磁石１０１を備える。可動磁石１０１は、２個の磁石１０２ａ，１０２ｂを備える。磁石１０２ａ，１０２ｂは、非磁性体のスペーサ１０３を介して、同極が向かい合うように接合される。振動型電磁発電機１００に振動が加わると、可動磁石１０１がソレノイドコイル１０４ａ，１０４ｂの巻き軸方向に往復振動し、発電する。
特表２００７−５２１７８５号公報 Patent Document 1 discloses a vibration type electromagnetic generator that generates electric power by vibration applied from the outside. Here, with reference to FIG. 10, the structural example of the vibration type electromagnetic generator 100 is demonstrated. The vibration electromagnetic generator 100 includes a hollow pipe 105, two solenoid coils 104 a and 104 b wound around the pipe 105, and a movable magnet 101 that can move inside the pipe 105. The movable magnet 101 includes two magnets 102a and 102b. The magnets 102a and 102b are joined through the non-magnetic spacer 103 so that the same poles face each other. When vibration is applied to the vibration type electromagnetic generator 100, the movable magnet 101 reciprocally vibrates in the direction of the winding axis of the solenoid coils 104a and 104b to generate power.
Special table 2007-521785 gazette

従来の振動型電磁発電機１００は、小型でありながら発電効率が高いという利点がある。発電効率を高めるには、Ｎｄ（ネオジム）磁石等に代表されるエネルギー積の大きな磁石を使用する必要がある。しかし、磁石１０２ａ，１０２ｂの同極を向かい合わせて近づけると互いの反発力が大きくなってしまう。このため、簡素なスペーサ１０３では磁石１０２ａ，１０２ｂを十分に支持し、固定できない。   The conventional vibration type electromagnetic generator 100 has an advantage of high power generation efficiency while being small. In order to increase the power generation efficiency, it is necessary to use a magnet having a large energy product, such as an Nd (neodymium) magnet. However, when the same poles of the magnets 102a and 102b are brought close to each other, the repulsive force between them increases. For this reason, the simple spacer 103 sufficiently supports the magnets 102a and 102b and cannot be fixed.

また、磁石１０２ａ，１０２ｂの同極を向かい合わせると互いに反発するため、例えば、複数個の磁石とスペーサを、まっすぐに接合することは極めて難しい。仮に、磁石が、わずかでも曲がって接合されると、可動磁石１０１の側面に凹凸が生じるため、可動磁石１０１とパイプ１０５の内壁面に生じる摩擦が大きくなってしまう。この摩擦を小さくするには、磁性流体や潤滑部材（例えば、ビーズ）等を用いなければならず、製造工程の増大、部材コストの高騰が懸念される。しかし、潤滑部材を用いなければ振動型電磁発電機１００の発電効率が下がってしまうという課題があった。   Further, when the same poles of the magnets 102a and 102b are opposed to each other, they repel each other. For example, it is extremely difficult to join a plurality of magnets and spacers straightly. If the magnet is bent and joined even slightly, the side surface of the movable magnet 101 is uneven, and the friction generated between the movable magnet 101 and the inner wall surface of the pipe 105 is increased. In order to reduce this friction, a magnetic fluid, a lubricating member (for example, a bead) or the like must be used, and there is a concern that the manufacturing process increases and the member cost increases. However, there is a problem in that the power generation efficiency of the vibration type electromagnetic generator 100 is lowered unless a lubricating member is used.

本発明はこのような状況に鑑みて成されたものであり、簡素な構成でかつ組立が容易でありながら、可動磁石とパイプとの摩擦が小さく、発電効率の高い振動型電磁発電機を提供することを目的とする。   The present invention has been made in view of such a situation, and provides a vibration type electromagnetic generator having a simple configuration and easy assembly, having a small friction between a movable magnet and a pipe, and high power generation efficiency. The purpose is to do.

本発明の振動型電磁発電機は、非磁性材料で形成され、両端部が閉じられた中空の第１のパイプと、第１のパイプの周囲に巻回され、少なくとも１個のソレノイドコイルが設けられた発電コイルと、第１のパイプの内部に配置され、発電コイルの巻軸方向に沿って移動可能である可動磁石と、を備える。そして、可動磁石は、非磁性材料で形成され、両端部が閉じられた中空の第２のパイプと、第２のパイプの内部に、第２のパイプの内壁面により強制的に整列され、封止される複数個の磁石と、を備える。 The vibration type electromagnetic generator according to the present invention includes a hollow first pipe formed of a nonmagnetic material and closed at both ends, wound around the first pipe, and provided with at least one solenoid coil. And a movable magnet disposed inside the first pipe and movable along the winding axis direction of the power generation coil. The movable magnet is forcibly aligned by the inner wall surface of the second pipe inside the second pipe and the hollow second pipe made of a nonmagnetic material and closed at both ends , and sealed. A plurality of magnets to be stopped.

このように振動型電磁発電機を構成することによって、可動磁石と第１のパイプの内壁面との摩擦が小さくなり、可動磁石が振動しやすくなる。   By configuring the vibration type electromagnetic generator in this way, the friction between the movable magnet and the inner wall surface of the first pipe is reduced, and the movable magnet is likely to vibrate.

本発明によれば、複数個の磁石を第２のパイプの内部に封止することで、可動磁石と第１のパイプの内壁面との摩擦が小さくなる。このため、わずかな振動が加わるだけで、可動磁石が振動しやすくなり、振動型電磁発電機の発電効率が高まるという効果がある。   According to the present invention, the friction between the movable magnet and the inner wall surface of the first pipe is reduced by sealing the plurality of magnets inside the second pipe. For this reason, even if slight vibration is applied, the movable magnet is likely to vibrate, and the power generation efficiency of the vibration type electromagnetic generator is increased.

以下、本発明の第１の実施の形態例について、図１〜図８を参照して説明する。本実施の形態例は、複数個のソレノイドコイルの中に、長さ方向に着磁された複数個の円筒形の磁石を振動または移動して発電する振動型電磁発電機１に適用したものである。   Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. This embodiment is applied to a vibration type electromagnetic generator 1 that generates power by vibrating or moving a plurality of cylindrical magnets magnetized in the length direction in a plurality of solenoid coils. is there.

まず、本例の振動型電磁発電機１の構成例について、図１の断面図を参照して説明する。振動型電磁発電機１は、可動磁石３と、第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃで構成される。３個のソレノイドコイルは、中空の第１のパイプ２の外周に巻き付けられる。第１のパイプ２は、非磁性材料で形成される。第１のパイプ２の材質は、金属等の非磁性材料であってもよいが、加工性等を考慮するとプラスチック等の合成樹脂で製造することが望ましい。第１のパイプ２の内部を、可動磁石３が直線往復運動（以下、単に振動とも言う。）すると、第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃに電圧が発生する。   First, the structural example of the vibration type electromagnetic generator 1 of this example is demonstrated with reference to sectional drawing of FIG. The vibration type electromagnetic generator 1 includes a movable magnet 3 and a first solenoid coil 4a to a third solenoid coil 4c. The three solenoid coils are wound around the outer periphery of the hollow first pipe 2. The first pipe 2 is made of a nonmagnetic material. The material of the first pipe 2 may be a non-magnetic material such as a metal, but it is preferable to manufacture the first pipe 2 from a synthetic resin such as plastic in consideration of workability and the like. When the movable magnet 3 reciprocates linearly (hereinafter simply referred to as vibration) inside the first pipe 2, a voltage is generated in the first solenoid coil 4a to the third solenoid coil 4c.

可動磁石３は、非磁性材料で形成された中空の第２のパイプ５と、第２のパイプ５の内部に封止され、同じ極性が対向して接合された複数個の磁石（例えば、ネオジム磁石）で構成される。可動磁石３の両端部には、第１の磁石３ａを保護する第１の磁石端部材８ａと、第３の磁石３ｃを保護する第２の磁石端部材８ｂが形成される。   The movable magnet 3 includes a hollow second pipe 5 made of a nonmagnetic material, and a plurality of magnets (for example, neodymium) that are sealed inside the second pipe 5 and have the same polarity opposed to each other. Magnet). At both ends of the movable magnet 3, a first magnet end member 8a that protects the first magnet 3a and a second magnet end member 8b that protects the third magnet 3c are formed.

長さ方向に着磁された同じ長さの第１の磁石３ａ〜第３の磁石３ｃは、所定の厚さの第１のスペーサ６ａと第２のスペーサ６ｂを介した上で、同じ極を向かい合わせて一体に接合される。このように、第１のスペーサ６ａと第２のスペーサ６ｂは、隣り合う磁石の間隔を空ける間隔部材として用いられる。第１のスペーサ６ａと第２のスペーサ６ｂの材質は、磁性体又は非磁性体のいずれでもよい。さらに、スペーサを介さない状態で複数個の磁石を同極対向させ、隣り合う磁石同士を接触させた際の減磁が、振動型電磁発電機の出力特性に大きく影響しないのであれば、磁石間にスペーサを介さなくてもよい。また、可動磁石３を構成する磁石は、複数個用いることが望ましい。第１の磁石３ａ〜第３の磁石３ｃと、第１のスペーサ６ａ，第２のスペーサ６ｂは、第２のパイプ５の内部に挿入された状態で、第２のパイプ５の両端に施される加締め加工によって、第２のパイプ５の内部に封止される。   The first magnet 3a to the third magnet 3c of the same length magnetized in the length direction have the same poles through the first spacer 6a and the second spacer 6b having a predetermined thickness. Face to face and joined together. Thus, the 1st spacer 6a and the 2nd spacer 6b are used as a spacing member which leaves the space | interval of adjacent magnets. The material of the first spacer 6a and the second spacer 6b may be either a magnetic material or a non-magnetic material. Furthermore, if the demagnetization when a plurality of magnets are opposed to each other with the same polarity and without contacting a spacer and the adjacent magnets are brought into contact with each other, the output characteristics of the vibration type electromagnetic generator will not be greatly affected. The spacer may not be interposed. Moreover, it is desirable to use a plurality of magnets constituting the movable magnet 3. The first magnet 3a to the third magnet 3c, the first spacer 6a, and the second spacer 6b are applied to both ends of the second pipe 5 while being inserted into the second pipe 5. The inside of the second pipe 5 is sealed by the caulking process.

なお、以下の説明において、第１のパイプ２の内壁面と可動磁石３が物理的に接触した状態で、相対的に移動する際に、互いの運動を互いに妨げる向きに力が働く現象を、「摩擦」と定義する。摩擦は、可動磁石３が振動する際にブレが生じ、第１のパイプ２の内壁面と可動磁石３との接触箇所や衝突回数が増えることによって発生し、可動磁石３の振動が減衰する要因となりうる。   In the following description, when the inner wall surface of the first pipe 2 and the movable magnet 3 are in physical contact with each other, when the relative movement is performed, a phenomenon in which force acts in a direction that interferes with each other's movement, It is defined as “friction”. Friction is generated when the movable magnet 3 vibrates and is caused by an increase in the number of contact points and the number of collisions between the inner wall surface of the first pipe 2 and the movable magnet 3, and a factor that attenuates the vibration of the movable magnet 3. It can be.

このような理由から、第１のパイプ２と、第１のパイプ２の内部に配置され、複数個の磁石が封止される第２のパイプ５のうち、少なくとも一方または双方に、ポリプロピレン（ＰＰ：polypropylene）等の摩擦係数が低い材質を用いることが望ましい。このような材質を用いることで、第１のパイプ２と第２のパイプ５の摩擦を低減させることができる。   For this reason, polypropylene (PP) is attached to at least one or both of the first pipe 2 and the second pipe 5 disposed inside the first pipe 2 and sealed with a plurality of magnets. : It is desirable to use a material with a low coefficient of friction, such as polypropylene. By using such a material, friction between the first pipe 2 and the second pipe 5 can be reduced.

第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃは、逆極性に直列接続された複数個のコイルであって、所定の間隔を空けた状態で第１のパイプ２に配置される。各ソレノイドコイルの巻き方向は、隣り合うソレノイドコイル毎に互いに逆向きの正・逆・正方向である。以下の説明では、直列接続された第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃを、発電コイル９と称する。第１のパイプ２には、少なくとも１個のソレノイドコイルが、発電コイル９として構成される。   The first solenoid coil 4a to the third solenoid coil 4c are a plurality of coils connected in series with opposite polarities, and are disposed on the first pipe 2 with a predetermined interval therebetween. The winding directions of the solenoid coils are forward, reverse, and forward directions that are opposite to each other for each adjacent solenoid coil. In the following description, the first solenoid coil 4 a to the third solenoid coil 4 c connected in series are referred to as a power generation coil 9. In the first pipe 2, at least one solenoid coil is configured as a power generation coil 9.

第１のパイプ２の両端部には、可動磁石３の飛び出しを防止するため、樹脂等で形成された第１の端部材７ａと第２の端部材７ｂがはめ込まれる。第１の端部材７ａと第２の端部材７ｂは、同形状であるが、これら端部材を、お互いに異形状としてもよい。このようにして、振動型電磁発電機１では、可動磁石３が発電コイル９の巻き軸方向に振動可能となる。そして、操作者が、振動型電磁発電機１を振ると、可動磁石３が発電コイル９の中を振動し、第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃで電圧が誘起される。   A first end member 7a and a second end member 7b made of resin or the like are fitted into both ends of the first pipe 2 in order to prevent the movable magnet 3 from jumping out. Although the first end member 7a and the second end member 7b have the same shape, these end members may have different shapes. In this manner, in the vibration type electromagnetic generator 1, the movable magnet 3 can vibrate in the winding axis direction of the power generation coil 9. When the operator swings the vibration type electromagnetic generator 1, the movable magnet 3 vibrates in the power generation coil 9, and a voltage is induced in the first solenoid coil 4a to the third solenoid coil 4c.

そして、第１のソレノイドコイル４ａ〜第３のソレノイドコイル４ｃが発生する電圧の位相を合わせて、合成することにより、振動型電磁発電機１が出力する電圧が増大する。そのためには、磁石長とスペーサの厚さを加えた磁石ピッチと、コイル長とコイル間隔を加えたコイルピッチを、ほぼ等しくする必要がある。さらに、ソレノイドコイルのコイル長は磁石長より短くすることが望ましい。この結果、安定して電圧が得られる。   And the voltage which the vibration type electromagnetic generator 1 outputs increases by combining and synthesizing the phase of the voltage which the 1st solenoid coil 4a-the 3rd solenoid coil 4c generate | occur | produce. For this purpose, the magnet pitch obtained by adding the magnet length and the spacer thickness and the coil pitch obtained by adding the coil length and the coil interval must be substantially equal. Furthermore, the coil length of the solenoid coil is preferably shorter than the magnet length. As a result, a voltage can be obtained stably.

次に、可動磁石３の断面構造の例について、図２を参照して説明する。
第１の磁石端部材８ａと第２の磁石端部材８ｂは、第２のパイプ５の両端部を確実に封止するために、熱可塑性樹脂又は熱硬化性樹脂によって形成される。第１の磁石端部材８ａと第２の磁石端部材８ｂは、後述するように第２のパイプ５と熱溶着により接合されるため、これらの材質は同じであることが望ましい。なお、第２のパイプ５と第１の磁石端部材８ａ，第２の磁石端部材８ｂを、接着剤等を用いて接着固定してもよい。ただし、接着性が良好な接着剤を用いるのであれば、第２のパイプ５と第１の磁石端部材８ａ，第２の磁石端部材８ｂの材質を同じにする必要はない。 Next, an example of a cross-sectional structure of the movable magnet 3 will be described with reference to FIG.
The first magnet end member 8a and the second magnet end member 8b are formed of a thermoplastic resin or a thermosetting resin in order to securely seal both ends of the second pipe 5. Since the first magnet end member 8a and the second magnet end member 8b are joined to the second pipe 5 by thermal welding as will be described later, it is desirable that these materials are the same. The second pipe 5, the first magnet end member 8a, and the second magnet end member 8b may be bonded and fixed using an adhesive or the like. However, if an adhesive with good adhesiveness is used, it is not necessary to use the same material for the second pipe 5, the first magnet end member 8a, and the second magnet end member 8b.

次に、可動磁石３の一方の端部の構成例について、図３を参照して説明する。図３は、可動磁石３に取り付けられる第１の磁石端部材８ａ付近を示す拡大図である。   Next, a configuration example of one end of the movable magnet 3 will be described with reference to FIG. FIG. 3 is an enlarged view showing the vicinity of the first magnet end member 8 a attached to the movable magnet 3.

第２のパイプ５に、第１の磁石３ａ〜第３の磁石３ｃを封止する工程では、第２のパイプ５の両端部に熱が加えられる。この工程において、熱可塑性樹脂で形成される第１の磁石端部材８ａを第２のパイプ５の端部（換言すれば、第２のパイプ５に配置される複数の磁石のうち、最も外側に配置される磁石の端部である。）に配置する。第２のパイプ５の端部に熱が加わると、第１の磁石端部材８ａと第２のパイプ５の端部が熱溶着し、熱溶着部１０が形成される。通常、この工程において、第１の磁石３ａ〜第３の磁石３ｃに熱が加わると磁気特性が著しく劣化してしまう。このため、第２のパイプ５の端部に第１の磁石端部材８ａを設けると、第１の磁石３ａ〜第３の磁石３ｃに熱が伝わりにくくなる。つまり、第１の磁石端部材８ａを第２のパイプ５の端部に配置する構成は、加熱手段によって封止処理を行う場合に特に望ましい形態であると言える。   In the process of sealing the first magnet 3 a to the third magnet 3 c to the second pipe 5, heat is applied to both ends of the second pipe 5. In this step, the first magnet end member 8a formed of a thermoplastic resin is placed on the end of the second pipe 5 (in other words, the outermost of the plurality of magnets arranged on the second pipe 5). It is the end of the magnet to be placed. When heat is applied to the end of the second pipe 5, the first magnet end member 8 a and the end of the second pipe 5 are thermally welded to form the heat welded portion 10. Usually, in this process, when heat is applied to the first magnet 3a to the third magnet 3c, the magnetic characteristics are remarkably deteriorated. For this reason, if the 1st magnet end member 8a is provided in the end of the 2nd pipe 5, it will become difficult to transmit heat to the 1st magnet 3a-the 3rd magnet 3c. That is, it can be said that the configuration in which the first magnet end member 8a is disposed at the end of the second pipe 5 is a particularly desirable form when the sealing process is performed by the heating means.

また、第２のパイプ５に、第１の磁石３ａ〜第３の磁石３ｃを封止する工程では、可動磁石３の両端部に接着剤１１が用いられる。接着剤１１は、使用する樹脂に対して十分な接着性を示す接着剤が用いられる。可動磁石３の両端部に用いられた接着剤１１は、第２のパイプ５と第１の磁石端部材８ａとの接合面に浸透する。そして、第２のパイプ５と第１の磁石端部材８ａは、強固に結合する。   Further, in the process of sealing the first magnet 3 a to the third magnet 3 c to the second pipe 5, the adhesive 11 is used at both ends of the movable magnet 3. As the adhesive 11, an adhesive exhibiting sufficient adhesiveness to the resin to be used is used. The adhesive 11 used at both ends of the movable magnet 3 penetrates into the joint surface between the second pipe 5 and the first magnet end member 8a. And the 2nd pipe 5 and the 1st magnet end member 8a are couple | bonded firmly.

なお、第２のパイプ５と第１の磁石端部材８ａの材質に、熱硬化性樹脂や非磁性金属を使用する場合、有機接着剤等を用いて、第２のパイプ５と第１の磁石端部材８ａを十分に接着固定する必要がある。このためには、第２のパイプ５と第１の磁石端部材８ａの隙間に接着剤が十分に流れ込むように、隙間の大きさや形を工夫するとよい。   In addition, when using a thermosetting resin or a nonmagnetic metal for the material of the 2nd pipe 5 and the 1st magnet end member 8a, the 2nd pipe 5 and the 1st magnet are used using an organic adhesive agent etc. It is necessary to bond and fix the end member 8a sufficiently. For this purpose, the size and shape of the gap may be devised so that the adhesive sufficiently flows into the gap between the second pipe 5 and the first magnet end member 8a.

このように、第２のパイプ５の内部に第１の磁石３ａ〜第３の磁石３ｃが封止され、接着剤等によって固定され、強度もまた向上する。このため、発電を行う際の振動によって可動磁石３に衝撃が加えられても、可動磁石が損傷する虞が小さくなる。
なお、可動磁石３の磁石端部材８ｂ付近についても、第１の磁石端部材８ａと同様の構成であるため、磁石端部材８ｂ付近の構成例については詳細な説明を省略する。 In this way, the first magnet 3a to the third magnet 3c are sealed inside the second pipe 5 and are fixed by an adhesive or the like, and the strength is also improved. For this reason, even if an impact is applied to the movable magnet 3 due to vibration during power generation, the possibility of damage to the movable magnet is reduced.
Note that the vicinity of the magnet end member 8b of the movable magnet 3 has the same configuration as that of the first magnet end member 8a, and therefore a detailed description of the configuration example near the magnet end member 8b is omitted.

次に、可動磁石３を組立てる可動磁石組立て装置２０の構成例と、可動磁石組立て装置２０を用いて行われる可動磁石３の製造方法の例について、図４〜図８を参照して説明する。
可動磁石３は、強い磁力を有する第１の磁石３ａ〜第３の磁石３ｃを備えるため、弱い磁力を有する磁石を用いた場合に比べて、振動型電磁発電機１の発電コイル９に生じる起電力が上がる。しかし、特に、スペーサを非磁性体とした場合や、スペーサを使用しない形態においては、各磁石の同極が対向すると、互いに磁石は強く反発する。このため、可動磁石３の製造方法には、特別な工夫が必要となる。 Next, a configuration example of the movable magnet assembling apparatus 20 for assembling the movable magnet 3 and an example of a method for manufacturing the movable magnet 3 performed using the movable magnet assembling apparatus 20 will be described with reference to FIGS.
Since the movable magnet 3 includes the first magnet 3a to the third magnet 3c having a strong magnetic force, the movable magnet 3 is generated in the power generation coil 9 of the vibration type electromagnetic generator 1 as compared with the case where a magnet having a weak magnetic force is used. The power goes up. However, in particular, when the spacer is made of a non-magnetic material or in a form in which the spacer is not used, the magnets strongly repel each other when the same poles of the magnets face each other. For this reason, a special device is required for the method of manufacturing the movable magnet 3.

図４は、第１の磁石３ａと第１のスペーサ６ａを、可動磁石組立て装置２０にセットした状態の例を示す。
可動磁石組立て装置２０は、長さに応じて第２のパイプ５を保持する位置決めストッパ部２１と、第２のパイプ５から磁石とスペーサが飛び出さないように、磁石とスペーサを押さえる飛び出し押さえ部２２と、磁石とスペーサを第２のパイプ５の内部に真っすぐ挿入するための挿入口を有する磁石ガイド２３と、磁石とスペーサを第２のパイプ５に押し込む押し棒２４と、押し棒２４の押込みを制御する押し棒制御装置２５と、を備える。 FIG. 4 shows an example of a state in which the first magnet 3 a and the first spacer 6 a are set in the movable magnet assembling apparatus 20.
The movable magnet assembling apparatus 20 includes a positioning stopper portion 21 that holds the second pipe 5 according to the length, and a pop-out pressing portion that presses the magnet and the spacer so that the magnet and the spacer do not jump out of the second pipe 5. 22, a magnet guide 23 having an insertion port for inserting a magnet and a spacer straight into the second pipe 5, a push rod 24 for pushing the magnet and the spacer into the second pipe 5, and a push of the push rod 24 And a push rod control device 25 for controlling.

第２のパイプ５の一方の端部は、事前に位置決めストッパ部２１に固定されており、磁石端部材８ａは、予め熱溶着や接着によって固定される。第１の磁石３ａには、第１のスペーサ６ａが接触した状態で、磁石ガイド２３にセットされる。   One end of the second pipe 5 is fixed to the positioning stopper 21 in advance, and the magnet end member 8a is fixed in advance by heat welding or adhesion. The first magnet 3a is set on the magnet guide 23 with the first spacer 6a in contact therewith.

図５は、セットした第１の磁石３ａと第１のスペーサ６ａ（図４参照）を、押し棒２４で第２のパイプ５に押し込んだ後、第２の磁石３ｂと第２のスペーサ６ｂを、可動磁石組立て装置２０にセットした状態の例を示す。   FIG. 5 shows that after the set first magnet 3a and first spacer 6a (see FIG. 4) are pushed into the second pipe 5 with the push rod 24, the second magnet 3b and the second spacer 6b are moved. The example of the state set to the movable magnet assembly apparatus 20 is shown.

図６は、セットした第２の磁石３ｂと第２のスペーサ６ｂ（図５参照）を、押し棒２４で第２のパイプ５に押し込んだ状態の例を示す。
第２のパイプ５の奥には、第１の磁石３ａが押し込まれており、第１の磁石３ａのＳ極が第２の磁石３ｂに向く。一方、第２の磁石３ｂは、第２の磁石３ｂのＳ極が第１の磁石３ａに向いた状態で、第２のパイプ５に挿入される。このように、第１の磁石３ａと第２の磁石３ｂの同極が対向するため、第１の磁石３ａと第２の磁石３ｂは互いに反発力が生じる。この反発力によって、第２のパイプ５から第２の磁石３ｂが飛び出すおそれがある。 FIG. 6 shows an example of a state in which the set second magnet 3 b and second spacer 6 b (see FIG. 5) are pushed into the second pipe 5 by the push rod 24.
The first magnet 3a is pushed into the back of the second pipe 5, and the south pole of the first magnet 3a faces the second magnet 3b. On the other hand, the second magnet 3b is inserted into the second pipe 5 with the S pole of the second magnet 3b facing the first magnet 3a. Thus, since the same polarity of the 1st magnet 3a and the 2nd magnet 3b opposes, the 1st magnet 3a and the 2nd magnet 3b produce repulsive force mutually. The repulsive force may cause the second magnet 3b to jump out of the second pipe 5.

そこで、第２の磁石３ｂが第２のパイプ５に完全に挿入されると、飛び出し押さえ部２２が動く。飛び出し押さえ部２２は、第２のパイプ５の内径より狭い位置まで動いて、第２のパイプ５から飛び出そうとする第２の磁石３ｂを押さえる。   Therefore, when the second magnet 3b is completely inserted into the second pipe 5, the pop-out pressing portion 22 moves. The pop-out pressing portion 22 moves to a position narrower than the inner diameter of the second pipe 5 and presses the second magnet 3 b that is about to jump out from the second pipe 5.

図７は、セットした第２の磁石３ｂと第２のスペーサ６ｂ（図６参照）を、押し棒２４で第２のパイプ５に押し込んだ後、第３の磁石３ｃと第２の磁石端部材８ｂを、可動磁石組立て装置２０にセットした状態の例を示す。   FIG. 7 shows that after the set second magnet 3b and the second spacer 6b (see FIG. 6) are pushed into the second pipe 5 by the push rod 24, the third magnet 3c and the second magnet end member are pressed. The example of the state which set 8b to the movable magnet assembly apparatus 20 is shown.

第２の磁石３ｂと第２のスペーサ６ｂは、押し棒２４が離れても、飛出し押さえ部２２により、第２のパイプ５の中に保持される。
３個以上の磁石を含む可動磁石を形成する場合、図５〜図７に示したように、可動磁石組立て装置２０に磁石をセットして、第２のパイプ５に押し込む工程を繰り返せばよい。 The second magnet 3b and the second spacer 6b are held in the second pipe 5 by the pop-out pressing portion 22 even when the push bar 24 is separated.
When forming a movable magnet including three or more magnets, as shown in FIGS. 5 to 7, the process of setting the magnet in the movable magnet assembling apparatus 20 and pushing it into the second pipe 5 may be repeated.

図８は、第２のパイプ５に、第３の磁石３ｃと第２の磁石端部材８ｂを押し込んだ状態の例を示す。
第３の磁石３ｃと第２の磁石端部材８ｂが押し棒２４に押し込まれると、反発力が作用して、第３の磁石３ｃは第２のパイプ５から飛び出そうとする。しかし、飛び出し押さえ部２２によって、第３の磁石３ｃの飛び出しが押さえられる。このため、押し棒２４が、第２の磁石端部材８ｂから離れても、第３の磁石３ｃは第２のパイプ５から飛び出さない。そして、加熱冶具（図示せず）により、第２のパイプ５と第２の磁石端部材８ｂの重なっている部分を、熱溶着や接着によって固定・封止、あるいは加締め加工できる。 FIG. 8 shows an example of a state in which the third magnet 3 c and the second magnet end member 8 b are pushed into the second pipe 5.
When the third magnet 3c and the second magnet end member 8b are pushed into the push rod 24, a repulsive force acts and the third magnet 3c tries to jump out of the second pipe 5. However, the pop-out pressing portion 22 suppresses the third magnet 3c from popping out. For this reason, even if the push rod 24 moves away from the second magnet end member 8 b, the third magnet 3 c does not jump out of the second pipe 5. Then, the overlapping portion of the second pipe 5 and the second magnet end member 8b can be fixed / sealed or crimped by heat welding or bonding with a heating jig (not shown).

また、第２のパイプ５と第１の磁石端部材８ａ，第２の磁石端部材８ｂを接着することによって、可動磁石３が一体に接合されるため、衝撃が加わっても容易に分解することがない。このとき用いる接着剤としては、使用する樹脂に対して十分に接着力が大きい接着剤を選定することは言うまでもない。   Moreover, since the movable magnet 3 is integrally joined by bonding the second pipe 5 with the first magnet end member 8a and the second magnet end member 8b, it can be easily disassembled even if an impact is applied. There is no. Needless to say, an adhesive having a sufficiently large adhesive strength to the resin to be used is selected as the adhesive used at this time.

以上説明した第１の実施の形態に係る振動型電磁発電機１を構成する可動磁石３は、対向する磁極が互いに同極となるように配置された複数個の磁石（第１の磁石３ａ〜第３の磁石３ｃ）を備える。これら複数個の磁石は、第２のパイプ５の内部に挿入されるという簡素な構成であるため、可動磁石３の組み立ては、極めて容易であるという効果がある。   The movable magnet 3 constituting the vibration-type electromagnetic generator 1 according to the first embodiment described above has a plurality of magnets (first magnets 3a to 3a) arranged so that opposing magnetic poles are the same. A third magnet 3c) is provided. Since the plurality of magnets have a simple configuration of being inserted into the second pipe 5, there is an effect that the assembly of the movable magnet 3 is extremely easy.

また、可動磁石３の形成工程は、第２のパイプ５の内壁面に沿って第１のスペーサ６ａ，第２のスペーサ６ｂを挿入するという簡単な作業のみである。そして、第２のパイプ５に挿入された複数個の磁石と、スペーサ、磁石端部材は、強制的に整列されるため、可動磁石３の外周面が歪まない。このため、可動磁石３が振動する際に、可動磁石３と第１のパイプ２の内壁面に生じていた不要な摩擦抵抗が抑えられる。この結果、発電効率に優れた振動型電磁発電機１を実現できるという効果がある。   Moreover, the formation process of the movable magnet 3 is only a simple operation of inserting the first spacer 6 a and the second spacer 6 b along the inner wall surface of the second pipe 5. And since the some magnet inserted in the 2nd pipe 5, a spacer, and a magnet end member are forcedly aligned, the outer peripheral surface of the movable magnet 3 does not distort. For this reason, when the movable magnet 3 vibrates, unnecessary frictional resistance generated on the inner wall surfaces of the movable magnet 3 and the first pipe 2 is suppressed. As a result, there is an effect that the vibration type electromagnetic generator 1 having excellent power generation efficiency can be realized.

また、第１のスペーサ６ａ，第２のスペーサ６ｂを介して、複数個の磁石が同極対向するため、発電コイル９に鎖交する磁束の磁束分布は、急激に大きくなる。この結果、振動型電磁発電機１の発電効率が高まるという効果がある。   In addition, since a plurality of magnets face each other with the same polarity through the first spacer 6a and the second spacer 6b, the magnetic flux distribution of the magnetic flux interlinking with the power generation coil 9 increases rapidly. As a result, there is an effect that the power generation efficiency of the vibration type electromagnetic generator 1 is increased.

また、第２のパイプ５と、第１の磁石端部材８ａ，第２の磁石端部材８ｂが樹脂材料で構成される場合には、加熱や溶剤による溶着処理を封止加工とすることができる。このため、可動磁石３の製造を容易化できるという効果がある。さらに、第１の磁石端部材８ａと第２の磁石端部材８ｂの材質を弾性部材として、両側の先端部を突起状に構成してもよい。この場合、可動磁石３が第１のパイプ２の端部材に衝突する衝撃を緩和するため、可動磁石３の破損を防ぐことができるという効果が得られる。   Moreover, when the 2nd pipe 5, and the 1st magnet end member 8a and the 2nd magnet end member 8b are comprised with a resin material, the welding process by a heating or a solvent can be made into a sealing process. . For this reason, there exists an effect that manufacture of the movable magnet 3 can be made easy. Furthermore, the material of the first magnet end member 8a and the second magnet end member 8b may be an elastic member, and the tip portions on both sides may be formed in a protruding shape. In this case, since the impact that the movable magnet 3 collides with the end member of the first pipe 2 is mitigated, an effect that the breakage of the movable magnet 3 can be prevented is obtained.

また、磁石とスペーサの外周径は、第２のパイプ５の内周径よりわずかに小さくしておくとよい。このようにしておくと、可動磁石組立て装置２０で可動磁石３を組立てる場合に、第２のパイプ５の内部に空気が圧縮されることがなく、押し棒２４の押下力に対する抵抗力とならない。または、磁石とスペーサに溝等を形成して、圧縮される空気を逃がしてもよい。   The outer diameters of the magnet and the spacer are preferably slightly smaller than the inner diameter of the second pipe 5. In this way, when the movable magnet 3 is assembled by the movable magnet assembling apparatus 20, air is not compressed inside the second pipe 5 and does not become a resistance force against the pressing force of the push rod 24. Or a groove | channel etc. may be formed in a magnet and a spacer, and the compressed air may be escaped.

なお、図４〜図８の説明では、非磁性体材料で形成された第２のパイプ５と、第１の磁石端部材８ａ及び第２の磁石端部材８ｂの材質として熱可塑性樹脂を用い、それらを熱溶着により接合した場合について説明した。しかし、非磁性体材料として熱硬化性樹脂を用いる場合でも、接着剤による固定手段を用いれば上述した第１の実施の形態とほぼ同じ製造方法で可動磁石３を製造できる。   In the description of FIGS. 4 to 8, a thermoplastic resin is used as the material of the second pipe 5 formed of a non-magnetic material, and the first magnet end member 8a and the second magnet end member 8b. The case where they were joined by heat welding was described. However, even when a thermosetting resin is used as the non-magnetic material, the movable magnet 3 can be manufactured by substantially the same manufacturing method as that of the first embodiment described above, if an adhesive fixing means is used.

また、可動磁石３の両端部には、第１の磁石端部材８ａと第２の磁石端部材８ｂが配置される。そして、第２のパイプ５の材質に、例えば、アルミニウムや銅、真鍮等に代表される非磁性金属を用いる。この場合、第２のパイプ５に複数個の磁石を挿入した後に、第２のパイプ５の両端部を加締め加工によって封止する。このような製造方法を用いると、第１の磁石端部材８ａと第２の磁石端部材８ｂが変形するのみであり、複数個の磁石の端部に不要な応力が加わったり、変形したりすることがない。また、複数個の磁石に対して熱が加わらないため、磁石の劣化が抑えられる。この結果、複数個の磁石が生じる磁束密度のバラつきを減らせるという効果がある。ただし、加締め加工の方法を最適化し、磁石に対して過度の応力を与えないようにすれば、磁石端部材８ａ，８ｂは必ずしも必須の構成にはならない。   Moreover, the 1st magnet end member 8a and the 2nd magnet end member 8b are arrange | positioned at the both ends of the movable magnet 3. As shown in FIG. And the non-magnetic metal represented by aluminum, copper, brass etc. is used for the material of the 2nd pipe 5, for example. In this case, after inserting a plurality of magnets into the second pipe 5, both ends of the second pipe 5 are sealed by caulking. If such a manufacturing method is used, only the 1st magnet end member 8a and the 2nd magnet end member 8b will deform | transform, and unnecessary stress will be added to the edge part of a several magnet, or will deform | transform. There is nothing. Moreover, since heat is not applied to a plurality of magnets, deterioration of the magnets can be suppressed. As a result, there is an effect that variations in magnetic flux density generated by a plurality of magnets can be reduced. However, the magnet end members 8a and 8b are not necessarily indispensable if the caulking method is optimized so as not to apply excessive stress to the magnet.

次に、本発明の第２の実施の形態に係る振動型電磁発電機３０の構成例について、図９を参照して説明する。なお、図９において、既に第１の実施の形態で説明した図１に対応する部分には同一符号を付し、詳細な説明を省略する。   Next, a configuration example of the vibration type electromagnetic generator 30 according to the second embodiment of the present invention will be described with reference to FIG. In FIG. 9, parts corresponding to those in FIG. 1 already described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

本例の振動型電磁発電機３０は、可動磁石３３の両端を２本のコイルバネ（引っ張りバネ）で吊るすバネ吊り方式としたことを特徴とする。
可動磁石３３は、第２のパイプ５と、第１のスペーサ６ａ，第２のスペーサ６ｂを介して、同極が対向するように第２のパイプ５に封止される第１の磁石３ａ〜第３の磁石３ｃと、第２のパイプ５の両端部に固定される第１の磁石端部材３１ａ，第２の磁石端部材３１ｂを備える。第１の磁石端部材３１ａには、第１のコイルバネ３４ａを取り付けるための細孔３５ａが形成される。第２の磁石端部材３１ｂには、第２のコイルバネ３４ｂを取り付けるための細孔３５ｂが形成される。 The vibration type electromagnetic generator 30 of the present example is characterized by a spring suspension system in which both ends of the movable magnet 33 are suspended by two coil springs (tensile springs).
The movable magnet 33 is sealed with the second pipe 5 so that the same poles face each other through the second pipe 5 and the first spacer 6a and the second spacer 6b. A third magnet 3c, a first magnet end member 31a and a second magnet end member 31b fixed to both ends of the second pipe 5 are provided. The first magnet end member 31a is formed with a pore 35a for attaching the first coil spring 34a. The second magnet end member 31b is formed with a pore 35b for attaching the second coil spring 34b.

可動磁石３を振動可能な状態で封止する第１のパイプ２の両端部には、可動磁石３の飛び出しを防ぐため、第１の端部材３２ａ，第２の端部材３２ｂが装着される。第１の端部材３２ａには、第１のコイルバネ３４ａを取り付けるための細孔３６ａが形成される。第２の端部材３２ｂには、第２のコイルバネ３４ｂを取り付けるための細孔３６ｂが形成される。   A first end member 32 a and a second end member 32 b are attached to both ends of the first pipe 2 that seals the movable magnet 3 in a state where the movable magnet 3 can vibrate in order to prevent the movable magnet 3 from popping out. The first end member 32a is formed with a pore 36a for attaching the first coil spring 34a. The second end member 32b is formed with a pore 36b for attaching the second coil spring 34b.

第１のコイルバネ３２ａの両端部は、細孔３５ａ，３６ａに取り付けられる。第２のコイルバネ３２ｂの両端部は、細孔３５ｂ，３６ｂに取り付けられる。このようにして、振動型電磁発電機３０は、２つのコイルバネで可動磁石３を吊るす共振系を構成する。可動磁石３３は、第２のパイプ５に複数の磁石とスペーサを封止した構成であり、可動磁石３３が発電コイル９の巻き軸方向に沿って共振振動することによって、発電コイル９で電圧が誘起される。   Both ends of the first coil spring 32a are attached to the pores 35a and 36a. Both ends of the second coil spring 32b are attached to the pores 35b and 36b. In this way, the vibration type electromagnetic generator 30 constitutes a resonance system in which the movable magnet 3 is suspended by two coil springs. The movable magnet 33 has a configuration in which a plurality of magnets and spacers are sealed in the second pipe 5, and the voltage is generated in the power generation coil 9 when the movable magnet 33 resonates along the winding axis direction of the power generation coil 9. Induced.

以上説明した第２の実施の形態に係る振動型電磁発電機３０は、第１の可動磁石３３を２本のコイルバネ（第１のコイルバネ３４ａと第２のコイルバネ３４ｂ）で支持する構成としている。第１のパイプ２の内壁面と第２のパイプ５の外壁面との摩擦が小さいため、２本のコイルバネと可動磁石３３との共振振動を最大限に利用できる。そして、発電機を上下に振る場合はもちろん、発電機を任意の向きで振動させたときでも、可動磁石３３が共振振動しやすくなり、少ない振動であっても、大きな電圧を得ることができるという効果がある。   The vibration type electromagnetic generator 30 according to the second embodiment described above is configured to support the first movable magnet 33 with two coil springs (a first coil spring 34a and a second coil spring 34b). Since the friction between the inner wall surface of the first pipe 2 and the outer wall surface of the second pipe 5 is small, the resonance vibration between the two coil springs and the movable magnet 33 can be utilized to the maximum. And even when the generator is shaken up and down, even when the generator is vibrated in an arbitrary direction, the movable magnet 33 tends to resonate, and a large voltage can be obtained even with a small amount of vibration. effective.

また、振動型電磁発電機３０は、微弱な振動エネルギーを効率的に可動磁石３３の直線往復運動に変換することができる。このため、重力方向に対して振動型電磁発電機３０が平行な状態であって、かつ振動型電磁発電機３０の設置方向が一定である場合、例えば、海上船舶の安全な航行のために波の上下運動によって発電し発光する発光ブイ等、への発電機として好適であると言える。また、自転車の荷台あるいはサドル、または、自動車のサスペンション部等に採用することも可能である。   Further, the vibration type electromagnetic generator 30 can efficiently convert the weak vibration energy into the linear reciprocating motion of the movable magnet 33. For this reason, when the vibration electromagnetic generator 30 is parallel to the direction of gravity and the installation direction of the vibration electromagnetic generator 30 is constant, for example, a wave for safe navigation of a marine vessel. It can be said that it is suitable as a power generator for a light emitting buoy that generates electric power by moving up and down. It can also be employed in a bicycle carrier or saddle, or in a car suspension.

なお、上述した第２の実施の形態では、可動磁石３３を２本のコイルバネ（第１のコイルバネ３４ａと第２のコイルバネ３４ｂ）で支持する構成としたが、コイルバネは少なくとも１本あればよい。この場合、可動磁石３３の重力方向（上側）に第１のコイルバネ３４ａを設置すればよい。   In the second embodiment described above, the movable magnet 33 is supported by two coil springs (the first coil spring 34a and the second coil spring 34b). However, at least one coil spring is sufficient. In this case, the first coil spring 34 a may be installed in the direction of gravity (upper side) of the movable magnet 33.

また、上述した第２の実施の形態では、２本の引っ張りバネを用いて可動磁石３３を支持する構成としたが、弾性体として２本の圧縮バネを用いてもよい。圧縮バネであっても、可動磁石３３の両端部を発電コイル９の巻軸方向に振動可能に支持することができる。
また、一個の圧縮バネのみを用いてもよい。この場合、圧縮バネを可動磁石３３の重力方向（下側）に設置するとともに、第２の磁石端部材３１ｂと第２の端部材３２ｂに圧縮バネを固定しておくことが望ましい。このような構成であっても、好適に発電を行うことが可能である。 In the above-described second embodiment, the movable magnet 33 is supported using two tension springs. However, two compression springs may be used as the elastic body. Even if it is a compression spring, both ends of the movable magnet 33 can be supported so as to vibrate in the winding axis direction of the power generation coil 9.
Further, only one compression spring may be used. In this case, it is desirable that the compression spring is installed in the gravity direction (lower side) of the movable magnet 33 and the compression spring is fixed to the second magnet end member 31b and the second end member 32b. Even with such a configuration, it is possible to suitably generate power.

また、上述した第１及び第２の実施の形態では、可動磁石３を構成する複数の磁石は、隣り合う磁石の同極を対向させて配置するようにしたが、異極を対向させて配置してもよい。この場合、隣り合う磁石は引き合うが、スペーサを介することで磁石間の間隔を空けた状態を保つことができる。   In the first and second embodiments described above, the plurality of magnets constituting the movable magnet 3 are arranged so that the same poles of adjacent magnets face each other, but are placed so that different poles face each other. May be. In this case, adjacent magnets attract each other, but a state where a gap between the magnets is provided can be maintained by using a spacer.

また、本発明の本質、すなわち可動磁石３の形成するため非磁性筒体である第２のパイプ５を用いることを考慮すると、可動磁石３を構成する複数個の磁石間に、磁石と同径を有したスペーサを配置することは必ずしも必須の構成ではない。   In consideration of the essence of the present invention, that is, the use of the second pipe 5 which is a non-magnetic cylindrical body for forming the movable magnet 3, the same diameter as the magnet is provided between the plurality of magnets constituting the movable magnet 3. It is not always essential to dispose a spacer having a gap.
