【発明の属する技術分野】
本発明は、振動発電機に係わり、更に詳しくは、磁気バネの振動を利用して発電する発電機の構造に係わるものである。
【0002】
【従来の技術】
近年携帯型の通信機器の普及は目覚しいものがある。これら携帯型の電子機器の電源には充電できる小型の電池が使用されているが、問題は、これら電池の容量が小さいために、頻繁な充電作業が必要になることである。使用頻度にもよるが、1〜3時間に1回程度の充電が必要になる場合もある。そこで、簡便に充電できる携帯型の充電器の開発が待望されている。特開平10−66323号公報、特開2000−308327号公報には、人、車の振動を利用して発電する発電機が開示されている。この発明は、バネで懸吊した永久磁石をコイルで取り囲み、人、車が動く時の振動で永久磁石を振動させ、コイルに起電力を誘起させるものである。
この方法の第一の欠点は、繰り返しの振動でバネが劣化し、長期間使用できないこと。第二の欠点は、永久磁石の外側にコイルを配する必要があり、しかも数千回のコイルの巻線回数が必要であるために、コイルの外径が大きくなり、装置全体としてはポケットに収納できるような小型化が難しい点である。第三の欠点は重量が重たいことである。以上の欠点がある。
【0003】
【発明が解決しようとする課題】
本発明はかかる問題点にかんがみてなされたもので、その目的は、スプリングを使用することなく長期間安定して永久磁石を振動させることが出来、高出力小型化が可能で、充電しながら使用もできる新しい構造の振動発電機を提供することである。
【0004】
【課題を解決するための手段】
本発明者は、上記問題に関して鋭意研究を行い、下記(1)〜(7)の手段で問題を解決できることを見出した。
すなわち、
(1)非磁性材料からなるパイプの両端に固定した永久磁石の間に、永久磁石からなる磁気振動子を配置した構造からなる磁気バネの、該固定した永久磁石と該振動子の間に電磁誘導コイルを配置した構造からなることを特徴とする振動発電機。

【0005】
【発明の実施の形態】
図面によって本発明の作用、機能を説明する。
図1、図2は本発明の磁気ばねの構造を説明した図である。
非磁性ケース1の両端には永久磁石2、3が固定されている。
2個の永久磁石2、3の間には、磁気振動子4が配置されている。振動子4は永久磁石からなり、両端の永久磁石2、3から離隔して
配置され、ケース1の中を上下自在、あるいは左右自在に動ける様になっている。振動子4の磁石の極性は、対向する永久磁石2、3の極性と同じにされており、互いに反発する関係にある。
【0006】
ケース1に外から振動を与えると、振動子4は上下(あるいは左右自在)に振動するようになる。振動子4が永久磁石2に接近すると、磁気的な反発力が働き、永久磁石3の方向に押しやられる。永久磁石3に接近すると再び永久磁石2の方向に押しやられる。このようにして振動子4は永久磁石2、3の間を往復振動することとなる。
【0007】
振動子4を形成する永久磁石は1個(図1)でも良いし、あるいは複数個直列(図2)に並べても良い。図1は1個の場合、図2は複数個並べた場合である。
複数個並べる時は、向かい合う面の極性は同じにして互いに反発する関係にする。同じ極性にするとくっついて1個の永久磁石になってしまうので好ましくない。
【0008】
図3〜図6は本発明発電機の構造を説明した図である。
図3、図4は、両端に固定した永久磁石と振動子の間に電磁誘導コイルを配置した時の説明図で、図4はコイルに鉄芯を入れたときの説明図である。
図5は振動子の外周にコイルを配置した時のコイルと振動子の位置関係の説明図、図6は振動子の外周にコイルを配置し、振動子は永久磁石を複数個直列に並べた時の説明図である。
【0009】
図3、図4で、樹脂あるいはステンレス鋼等の非磁性ケース1の両端に永久磁石2、3が固定されている。
永久磁石2、3の間には磁性振動子4が配置され、振動子4と永久磁石2、3の間には電磁誘導コイル5が配置されている。
振動子4は永久磁石で出来ており、その極性は対向する永久磁石2、3の極性(N、S)と同じ極性にされており、互いに反発する関係にある。
振動子4は永久磁石2、3の間で、磁力的にバランスの取れた位置に静止する。外から振動を与えられて振動子4が永久磁石2に接近すると、磁気的な反発力が働き、永久磁石3の方向に押しやられる。永久磁石3に接近すると再び永久磁石2の方向に押しやられる。このようにして振動子4は永久磁石2、3の間を往復振動することとなる。
【0010】
振動子4が永久磁石2、3に接近したり離れたりしてコイルを横切る磁束が変化することによってコイルに起電力が誘起されることとなる。
【0011】
図4に示した様にコイルに予め高透磁率の鉄芯を入れておくと、コイルにはより高い起電力が誘起される。高透磁率材料としては、電磁軟鉄、珪素鋼板、パーマロイ、センダスト、Fe−Al合金、アモルファス合金、軟磁性フェライト等、通常この種の用途に使用されている材料は全て使用できる。
【0012】
コイルと振動子の位置関係は、コイルに誘起される起電力が最大になる位置に設定する。即ち、振動子の少なくとも一方の端(図5の振動子のN極)がコイルの上端を出入りする時、及びコイルの全長の中で振動する時に、誘起起電力が最も大きくなるので、コイルと振動子はこのような位置関係に設定する。図5で点線は、振動子が振動するときの上死点、下死点の位置を示す。振動子は上の点線の位置と下の点線の位置の間で振動する。
【0013】
コイルの数と振動子の永久磁石の数は必ずしも同数でなくても良い。図6の様に、振動子の永久磁石が3個、コイルが2個で、永久磁石の数が多くても良いし、またコイルの数が多くても良い。
【0014】
本発明発電機の振動子を振動させる為の好ましい振動周波数の範囲は概ね3.5Hz以上の範囲である。3.5Hz未満では、振動子は共振することがないため,多くの発電電力は望めない。自動車のエンジンの振動、風、波、橋梁の振動、人が激しく動く時では3.5Hz以上の振動が得られるので、これらに積載、あるいは人が所持して発電機として利用できる。また本発明発電機は、加速度を与えると振動が発生し、誘起起電力は加速度の大きさに比例するので、加速度計としても利用できる。
【0015】
本発明発電機では交流が誘起される。そのまま使用しても良いが、
コイルの端末に整流器を接続して直流に変換して、あるいは変換した直流は更にレギュレーターで電圧を昇圧して、電池の充電に使用できる。
【0016】
発電電圧を高くする場合、一坦直流変換して、極性を整合させて直列に接続して電圧を高くする。
【0017】
本発明は、人、車等の携帯積載型電子機器の電源として直接利用しても良いし、又電池に充電するだけのために利用しても良いし、あるいは直接電源と充電の両方に同時に利用できるようにしてもよい。
【0018】
本発明の発電機は、少なくとも3.5Hz以上の振動数の振動は全て利用できるものであり、特定の振動源、揺動源の種類に何ら限定されるものではない。
【0019】
本発明に使用する電磁誘導コイルは巻き線型のコイルからシート状のコイルまで形状に何ら制約を受けることなく使用できる。又シート状コイルでは、丸、四角、楕円形状等いかなる形状でも良い。

BACKGROUND OF THE INVENTION
The present invention relates to a vibration power generator, and more particularly to a structure of a power generator that generates power using vibration of a magnetic spring.
[0002]
[Prior art]
In recent years, there has been a remarkable spread of portable communication devices. A small battery that can be charged is used as the power source of these portable electronic devices, but the problem is that the capacity of these batteries is so small that frequent charging work is required. Depending on the frequency of use, charging may be required about once every 1-3 hours. Therefore, development of a portable charger that can be easily charged is awaited. Japanese Patent Application Laid-Open No. 10-66323 and Japanese Patent Application Laid-Open No. 2000-308327 disclose generators that generate power using vibrations of people and vehicles. According to the present invention, a permanent magnet suspended by a spring is surrounded by a coil, and the permanent magnet is vibrated by vibration when a person or a vehicle moves to induce an electromotive force in the coil.
The first disadvantage of this method is that the spring deteriorates due to repeated vibration and cannot be used for a long time. The second disadvantage is that it is necessary to arrange the coil outside the permanent magnet, and the coil has to be wound several thousand times, which increases the outer diameter of the coil, and the entire device is in a pocket. It is difficult to reduce the size so that it can be stored. The third disadvantage is that it is heavy. There are the above disadvantages.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of such problems, and its purpose is to stably vibrate permanent magnets for a long period of time without using a spring, enabling high output miniaturization and use while charging. It is to provide a vibration generator with a new structure.
[0004]

(4) The vibration generator in any one of.
(7) The vibration generator according to any one of (1) to (6), wherein a vibration frequency of the vibrator is 3.5 Hz or more.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The operation and function of the present invention will be described with reference to the drawings.
1 and 2 are views for explaining the structure of the magnetic spring of the present invention.
Permanent magnets 2 and 3 are fixed to both ends of the nonmagnetic case 1.
A magnetic vibrator 4 is arranged between the two permanent magnets 2 and 3. The vibrator 4 is made of a permanent magnet, and is arranged apart from the permanent magnets 2 and 3 at both ends, so that it can move in the case 1 up and down or left and right. The polarities of the magnets of the vibrator 4 are the same as the polarities of the permanent magnets 2 and 3 facing each other, and are in a repulsive relationship.
[0006]
When vibration is applied to the case 1 from the outside, the vibrator 4 vibrates up and down (or left and right freely). When the vibrator 4 approaches the permanent magnet 2, a magnetic repulsive force works and is pushed in the direction of the permanent magnet 3. When approaching the permanent magnet 3, it is pushed again in the direction of the permanent magnet 2. In this way, the vibrator 4 reciprocates between the permanent magnets 2 and 3.
[0007]
The number of permanent magnets forming the vibrator 4 may be one (FIG. 1), or a plurality of permanent magnets may be arranged in series (FIG. 2). FIG. 1 shows the case of one, and FIG. 2 shows the case of arranging a plurality.
When arranging a plurality, the opposite faces have the same polarity and are repelled from each other. If they have the same polarity, they will stick to one permanent magnet, which is not preferable.
[0008]
3-6 is a figure explaining the structure of this invention generator.
3 and 4 are explanatory views when an electromagnetic induction coil is arranged between a permanent magnet fixed at both ends and a vibrator, and FIG. 4 is an explanatory view when an iron core is put in the coil.
FIG. 5 is an explanatory diagram of the positional relationship between the coil and the vibrator when the coil is arranged on the outer periphery of the vibrator. FIG. 6 is a diagram showing the coil arranged on the outer circumference of the vibrator, and the vibrator has a plurality of permanent magnets arranged in series. It is explanatory drawing at the time.
[0009]
3 and 4, permanent magnets 2 and 3 are fixed to both ends of a nonmagnetic case 1 made of resin or stainless steel.
A magnetic vibrator 4 is disposed between the permanent magnets 2 and 3, and an electromagnetic induction coil 5 is disposed between the vibrator 4 and the permanent magnets 2 and 3.
The vibrator 4 is made of a permanent magnet. The polarity of the vibrator 4 is the same as that of the opposing permanent magnets 2 and 3 (N, S), and they are repelled.
The vibrator 4 is stationary between the permanent magnets 2 and 3 at a magnetically balanced position. When vibration is applied from the outside and the vibrator 4 approaches the permanent magnet 2, a magnetic repulsive force works and is pushed toward the permanent magnet 3. When approaching the permanent magnet 3, it is pushed again in the direction of the permanent magnet 2. In this way, the vibrator 4 reciprocates between the permanent magnets 2 and 3.
[0010]
When the vibrator 4 approaches or separates from the permanent magnets 2 and 3 and the magnetic flux across the coil changes, an electromotive force is induced in the coil.
[0011]
As shown in FIG. 4, when an iron core having a high magnetic permeability is placed in the coil in advance, a higher electromotive force is induced in the coil. As the high magnetic permeability material, all materials usually used for this type of application such as electromagnetic soft iron, silicon steel plate, permalloy, sendust, Fe-Al alloy, amorphous alloy, soft magnetic ferrite, etc. can be used.
[0012]
The positional relationship between the coil and the vibrator is set to a position where the electromotive force induced in the coil is maximized. That is, when at least one end of the vibrator (N pole of the vibrator in FIG. 5) moves in and out of the upper end of the coil and vibrates in the entire length of the coil, the induced electromotive force becomes the largest. The vibrator is set in such a positional relationship. In FIG. 5, dotted lines indicate the positions of the top dead center and the bottom dead center when the vibrator vibrates. The vibrator vibrates between the position of the upper dotted line and the position of the lower dotted line.
[0013]
The number of coils and the number of permanent magnets of the vibrator are not necessarily the same. As shown in FIG. 6, the vibrator has three permanent magnets and two coils, and the number of permanent magnets may be large or the number of coils may be large.
[0014]
A preferable range of vibration frequency for vibrating the vibrator of the generator of the present invention is approximately 3.5 Hz or more. If the frequency is less than 3.5 Hz, the vibrator does not resonate, so a large amount of generated power cannot be expected. When an automobile engine vibrates, wind, waves, bridge vibration, or a person moves violently, vibrations of 3.5 Hz or higher can be obtained, and these can be loaded or carried by a person and used as a generator. Moreover, since the generator of the present invention generates vibration when acceleration is applied and the induced electromotive force is proportional to the magnitude of acceleration, it can also be used as an accelerometer.
[0015]
In the generator of the present invention, alternating current is induced. You can use it as is,
A rectifier is connected to the end of the coil to convert it to direct current, or the converted direct current can be further boosted by a regulator and used to charge the battery.
[0016]
When increasing the generated voltage, DC conversion is performed for one carrier, the polarity is matched, and the voltage is increased by connecting in series.
[0017]
The present invention may be used directly as a power source for a portable electronic device such as a person or a car, may be used only for charging a battery, or may be used for both direct power supply and charging at the same time. It may be made available.
[0018]
The generator according to the present invention can use all vibrations having a frequency of at least 3.5 Hz, and is not limited to any particular vibration source or type of oscillation source.
[0019]
The electromagnetic induction coil used in the present invention can be used without any restrictions on the shape from a wound coil to a sheet coil. Further, the sheet-like coil may have any shape such as a round shape, a square shape, or an oval shape.
[0020]
As the permanent magnet, any manufacturing method such as a cast magnet, a sintered magnet, or a magnet in which permanent magnet particles are hardened with plastic can be used.
As the shape of the permanent magnet, any shape from a rod shape, a disc shape to a ring shape can be appropriately adopted.
[0021]
