Description

この発明は、磁石が持つ磁気エネルギーを利用する自家発電装置に関するものである。The present invention relates to a private power generation device that uses magnetic energy of a magnet.

従来自転車用の発光装置は電池を電源として用いたものと自家発電式のものがある。
自家発電式は、誘導コイルと磁石を自転車の車体の一部に別々に取り付けて電磁誘導作用による発電を行っている。Conventional light emitting devices for bicycles include those using a battery as a power source and those using a self-power generation type.
In the private power generation type, an induction coil and a magnet are separately attached to a part of a bicycle body to generate power by electromagnetic induction.

電池式の場合、定期的に電池を交換しなければならないので経済的負担が生ずる。また、電磁誘導作用による自家発電式を用いたタイプの場合、磁石をスポークに装着し発光素子を持つ誘導コイルを自転車本体に装着するものがある。この場合、前記スポークが強い衝撃を受けて破損した場合に、前記磁石が前記スポークから離脱することが考えられる。本発明はこれらの課題を解決する。In the case of the battery type, an economic burden arises because the battery must be periodically replaced. Further, in the case of a type using a self-power generation system using electromagnetic induction, there is a type in which a magnet is attached to a spoke and an induction coil having a light emitting element is attached to a bicycle body. In this case, it is conceivable that the magnet is detached from the spoke when the spoke is damaged due to a strong impact. The present invention solves these problems.

前記従来の課題を解決するために、本発明の「自転車用自家発電式発光装置」は、筒の周上に発光素子を接続した誘導コイルを置き、筒の開口部に取り付けた回転軸を持つ磁石が可動すると、近接する前記誘導コイルとの間に電磁誘導が働き発光素子を発光させることを特徴とする。ここからは「自転車用自家発電式発光装置」を「前記装置」と表す。また、回転軸を持つ磁石を「前記磁石」と表す。In order to solve the above-described conventional problems, the “self-powered light emitting device for bicycles” of the present invention has a rotating shaft attached to an opening of a cylinder by placing an induction coil connected to a light emitting element on the circumference of the cylinder. When the magnet moves, electromagnetic induction acts between the adjacent induction coils to cause the light emitting element to emit light. From here on, “bicycle self-powered light emitting device” is referred to as “the device”. Further, a magnet having a rotation axis is referred to as “the magnet”.

前記誘導コイルは前記筒の周上、又は、前記磁石の左右の近接する位置に設置する。
本発明は電磁誘導作用による発電なので、前記磁石が可動し前記筒の周上に位置する前記誘導コイルや、前記磁石の左右に位置する前記誘導コイルに対し磁束の変化を与えなければならない。そのためにはスムーズに可動するのが望ましい。そのための手段として前記磁石の回転軸にベアリング等を装着する方法がある。The induction coil is installed on the circumference of the cylinder or at positions adjacent to the left and right of the magnet.
Since the present invention generates power by electromagnetic induction, the magnetic flux must be changed with respect to the induction coil that is movable and located on the circumference of the cylinder, and the induction coil that is positioned on the left and right of the magnet. For that purpose, it is desirable to move smoothly. As a means for that, there is a method of mounting a bearing or the like on the rotating shaft of the magnet.

本発明の前記装置は、前記磁石を可動させる方法として自転車の車輪を構成するスポークを利用するもので、前記装置を取り付けた装置取り付け具を前記車輪の前記車軸に装着し、前記スポークと前記装置が間近になるようにする。この状態で前記車輪を回転させて前記装置と前記スポークを交差させると、複数の前記スポークが連続で前記磁石上を通過する。両者が交差するとき前記磁石が前記スポークを吸引するので、交差する両者の間には断続的に磁気エネルギーが発生する。断続的に発生する磁気エネルギーは両者間に磁気の変動も起こす。The device of the present invention uses a spoke constituting a wheel of a bicycle as a method of moving the magnet, and a device mounting tool to which the device is mounted is mounted on the axle of the wheel, and the spoke and the device To be close. When the wheel is rotated in this state to cross the device and the spoke, a plurality of the spokes pass continuously on the magnet. When the two intersect, the magnet attracts the spoke, so that magnetic energy is intermittently generated between the two intersecting. Intermittently generated magnetic energy also causes magnetic fluctuations between them.

この時、前記磁石は変動を繰り返す磁気エネルギーの影響を受け自ら可動する。可動状態の前記磁石から発生する磁束の変化により、前記装置内で近接関係にある前記誘導コイルと前記磁石との間に電磁誘導が働き起電力が発生する。本発明者はこの現象に注目し、かかる課題を解決する手段とする。At this time, the magnet moves by itself under the influence of magnetic energy that repeatedly fluctuates. Due to a change in magnetic flux generated from the movable magnet, electromagnetic induction works between the induction coil and the magnet that are in close proximity within the device, and an electromotive force is generated. The inventor pays attention to this phenomenon and uses it as a means for solving such a problem.

前記装置を前記車軸に装着するための取り付け具が必要となる。また、前記装置と前記スポークは間近に位置するので両者の衝突が考えられる。この対策として、前記装置取り付け具の形状をＬ字型にする。一辺を前記スポーク側に向け、もう一辺を前記車輪の前記車軸に取り付ける側に使用する。前記スポークの間近に位置する辺の長さを限定することで前記装置と前記スポークの衝突を防ぐ。また、前記スポーク側に位置する辺の前記装置取り付け面の前記装置取り付け穴の形状を長方形にして縦長にするのが望ましい。これは、前記スポークと前記装置の離隔距離の調整をするためである。An attachment for attaching the device to the axle is required. Moreover, since the said apparatus and the said spoke are located close | similar, the collision of both is considered. As a countermeasure against this, the shape of the device attachment is made L-shaped. One side is directed to the spoke side and the other side is used on the side of the wheel attached to the axle. The collision between the device and the spoke is prevented by limiting the length of the side located close to the spoke. In addition, it is desirable that the shape of the device mounting hole on the device mounting surface on the side located on the spoke side is a rectangular shape and is vertically long. This is to adjust the separation distance between the spoke and the device.

前記スポークと交差する度に可動する前記磁石は強く激しく可動する方が好ましい。なぜならば近接する前記誘導コイルに対して磁束を切る早さが増した方が前記誘導コイルの両端に発生する起電力が大きくなるからである。これを実現するために前記磁石が取り付けられている前記筒内後方の近接する位置に補助磁石を設置する手段を用いる。It is preferable that the magnet that moves each time it intersects with the spoke moves strongly and vigorously. This is because the electromotive force generated at both ends of the induction coil increases as the speed of cutting the magnetic flux with respect to the adjacent induction coils increases. In order to realize this, means for installing an auxiliary magnet at a position close to the rear in the cylinder to which the magnet is attached is used.

前記磁石は前記車輪が停止している状態において、後方に位置する前記補助磁石と異極同士にあり、お互いに吸引し合うので静止状態を保つ。前記車輪が回転すると、交差する前記スポークを吸引するので前記磁石は可動する。この結果、補助磁石と同極状態になり互いに反発し合う。前記磁石は前記スポークの影響を受けることで前記補助磁石との間で吸引と反発の動作を繰り返すことで鋭い動きを示す。本発明は、前記筒内部に補助磁石を設置する手段を取り入れて発電能力を高めることを目指す。In the state where the wheel is stopped, the magnet is in a different polarity from the auxiliary magnet located at the rear, and attracts each other, so that the stationary state is maintained. When the wheels rotate, the magnets move because they attract the spokes that intersect. As a result, they are in the same pole state as the auxiliary magnet and repel each other. The magnet is sharply moved by repeating the attraction and repulsion operations with the auxiliary magnet under the influence of the spoke. The present invention aims to increase the power generation capacity by incorporating means for installing an auxiliary magnet inside the cylinder.

以上の手段を用いることで電池を必要としない理想の自家発電装置を完成させる。また、前記磁石と前記誘導コイルが近接状態にあり、ひとつの装置内に位置しているので、磁石の離脱や紛失等の問題を解消することも可能となりかかる課題の解決につながる。By using the above means, an ideal private power generator that does not require a battery is completed. In addition, since the magnet and the induction coil are close to each other and are located in one device, it is possible to solve problems such as detachment and loss of the magnet, and to solve such problems.

本発明は、発電発光に必要なものをひとつのケースに入れ、前記自転車の前記車輪を構成する前記スポークの間近に位置させ、前記スポークを利用することで自家発電する事を可能にした。これにより電池を使用しなくなるので二酸化炭素を排出しない地球に優しい自家発電式発光装置の誕生となった。According to the present invention, what is necessary for power generation and light emission is put in one case, positioned close to the spoke constituting the wheel of the bicycle, and self-power generation is possible by using the spoke. This eliminates the use of batteries, resulting in the birth of an earth-friendly self-powered light emitting device that does not emit carbon dioxide.

以下、本発明の実施の形態について、［図−１］［図−２］［図−３］［図−４］を用いて説明する。Hereinafter, embodiments of the present invention will be described with reference to [FIG. 1] [FIG. 2] [FIG. 3] [FIG.

［図−１］［図−２］に示すように、筒の周上に誘導コイル１１ａを取り付け、筒内部の空洞部分１９の最後部に補助磁石１４を取り付ける。回転軸を持つ磁石１０の軸にベアリング１５を装着し筒前部１６の開口部に取り付ける。次に基盤１３を筒後部１７に取り付ける。誘導コイル１１ａの両端末１８と発光素子１２ａを基盤１３の上で接続する。最後に筒の台座にカバー２０を取り付けて全体を覆う。ここからは筒の台座２１を含めカバー２０で覆った全ての物をひとつの単体として扱い「前記装置」と表す。
［図−３］［図−４］に示すように、誘導コイル１１ｂを回転軸を持つ磁石１０の左右のいずれかの位置に取りつける方法も用いる。[FIG. 1] As shown in [FIG. 2], an induction coil 11a is attached on the periphery of the cylinder, and an auxiliary magnet 14 is attached to the rearmost portion of the hollow portion 19 inside the cylinder. A bearing 15 is attached to the shaft of the magnet 10 having a rotation shaft and attached to the opening of the cylinder front portion 16. Next, the base 13 is attached to the cylinder rear portion 17. Both terminals 18 of the induction coil 11 a and the light emitting element 12 a are connected on the base 13. Finally, the cover 20 is attached to the base of the cylinder to cover the whole. From here on, all the objects covered with the cover 20 including the cylindrical base 21 will be treated as a single unit and represented as “the device”.
[Fig. 3] As shown in [Fig. 4], a method of attaching the induction coil 11b to either the left or right position of the magnet 10 having the rotation axis is also used.

次に、前記装置の取り付け具２２の形状と仕組みを説明する。長方形の金属製の板をＬ字に曲げ、前記装置取り付け面の穴２３を長方形にして２列設けた。さらに車軸２７に取り付けるための穴２４も長方形にした。前記装置の台座の底にはビス穴が２カ所ある。

A rectangular metal plate was bent into an L shape, and the holes 23 on the device mounting surface were rectangular and provided in two rows. Furthermore, the hole 24 for attaching to the axle 27 is also rectangular. There are two screw holes on the bottom of the base of the device.
The device mounting screw 25 is used to attach to the hole 23 on the device mounting surface. Next, the attachment 22 is attached to the axle 27 of the bicycle. At this time, the separation distance at which the magnet having the rotation shaft in the apparatus attracts the spoke is set.

本発明の、自転車用自家発電式発光装置の原理と動作について［図−１］［図−２］［図−３］［図−４］を用いて説明する。The principle and operation of the self-powered light emitting device for bicycles of the present invention will be described with reference to [FIG. 1] [FIG. 2] [FIG. 3] [FIG.

本発明品は回転軸を持つ磁石１０を可動させる方法として前記自転車の前記車輪のスポーク２６を利用する。そのために、前記装置を前記自転車の車軸２７に装着する冶具が必要となる。本発明者は長方形の板をＬ字型にした。これは、Ｌ字型にして一辺の面に前記装置を取り付け、もう片方の面を使用して前記装置を取り付けた取りつけ具２２を前記自転車の車軸２７に取り付けて使用する。The product of the present invention utilizes the spokes 26 of the wheel of the bicycle as a method of moving the magnet 10 having a rotating shaft. For this purpose, a jig for mounting the device on the axle 27 of the bicycle is required. The inventor made the rectangular plate L-shaped. This is L-shaped and the device is attached to one side, and the fixture 22 with the device attached to the other side is attached to the axle 27 of the bicycle.

前記装置内の回転軸を持つ磁石１０がスポーク２６を吸引する位置に前記装置を取りつけるため、間近に位置するスポーク２６と前記装置の衝突が考えられるので、本発明者は取り付け具に使用する板の素材と厚さと幅を研究した。素材には非磁性体の金属体を使用する。非磁性体の金属体を採用した理由は、磁性体の金属を使用すると前記装置内の回転軸を持つ磁石１０が装置取り付け具２２を吸引するので、回転軸を持つ磁石１０がスムーズに可動をしなくなるからである。Since the magnet 10 having the rotation axis in the device attaches the device to a position where the spoke 26 is attracted, the collision between the spoke 26 and the device is considered, so the present inventor is a plate used for the fixture. I studied the material, thickness and width. The material is a non-magnetic metal body. The reason for adopting the non-magnetic metal body is that when the magnetic metal is used, the magnet 10 having the rotating shaft in the device attracts the device attachment 22, so that the magnet 10 having the rotating shaft can move smoothly. Because it will not.

金属体を使用して板の幅を広めに設定したことで強度が増し、曲がりやたわみが発生することなく堅牢さを持つ取り付け具となった。これにより、転倒等の衝撃を受けても本発明品は近接するスポーク２６との衝突は避けることが出来る。
また、スポーク２６と間近に位置する前記装置が衝突しないように、前記装置取り付け面の先端がスポーク２６に当たらない長さに限定したで装置の破損は避けられる。By using a metal body and setting the width of the plate wider, the strength increased, and the fixture became robust without bending or bending. As a result, the product of the present invention can avoid a collision with the adjacent spoke 26 even if it receives an impact such as a fall.
Further, the device is prevented from being damaged by limiting the length of the device mounting surface so that it does not hit the spoke 26 so that the device located close to the spoke 26 does not collide.

本発明の前記装置は前記自転車の回転によりスポーク２６と交差し、前記装置内の回転軸を持つ磁石１０がスポーク２６を吸引することで、スポーク２６との間に磁気エネルギーを発生させる。その影響を自らが受けて可動し、近接する誘導コイルとの間に電磁誘導を働かせて発電する仕組みになっている。ここで、スポーク２６の破損により前記装置内の磁石との間に吸引作用が働かなくなる心配も考えられるが、スポーク２６は複数本存在するので残りのスポーク２６が役目を果たすことが出来るので心配ない。The apparatus of the present invention intersects with the spokes 26 by the rotation of the bicycle, and the magnet 10 having the rotation axis in the apparatus attracts the spokes 26 to generate magnetic energy between the spokes 26. It is a mechanism that moves by receiving the influence, and generates electric power by using electromagnetic induction between adjacent induction coils. Here, there is a possibility that the attraction action does not work with the magnet in the apparatus due to the breakage of the spokes 26, but there is no concern because there are a plurality of spokes 26 so that the remaining spokes 26 can play a role. .

回転軸を持つ磁石１０がスポーク２６や補助磁石１４の影響を受け可動することで、近接する誘導コイル１１ａや１１ｂとの間に電磁誘導が働き起電力が発生する原理を簡単に説明する。回転軸を持つ磁石１０は筒前部１６の開口部に取り付けられていて、前記車輪が回転することによりスポーク２６や補助磁石１４の影響を受けて回転を伴う動きをする。このとき間近に位置する誘導コイル１１ａや１１ｂに対して磁束を切り電磁誘導が働くのである。The principle that the electromagnetic induction is generated between the adjacent induction coils 11a and 11b and the electromotive force is generated when the magnet 10 having the rotating shaft moves under the influence of the spoke 26 and the auxiliary magnet 14 will be briefly described. The magnet 10 having a rotating shaft is attached to the opening of the cylinder front portion 16 and moves with rotation under the influence of the spoke 26 and the auxiliary magnet 14 as the wheel rotates. At this time, the magnetic flux is cut off to the induction coils 11a and 11b located close to each other, and electromagnetic induction works.

前記装置内の回転軸を持つ磁石１０がスポーク２６を吸引するためには両者の離隔距離が課題となる。前記Ｌ字型の取り付け具の前記装置を取り付ける穴の形状２３を長方形にしたことにより、装置を前後にスライドさせて最良の離隔距離を設定する事が出来る。
車軸２７に取り付ける穴２４も同様に長方形にしたので上下動が可能となり、前記車輪の径の異なる自転車にも装着が出来る。また、車軸２７に装着する際に前記装置の傾きも自由に設定できるので発光素子の照射角度の調整も出来る。In order for the magnet 10 having the rotating shaft in the apparatus to attract the spoke 26, the distance between them is a problem. By making the shape 23 of the hole for attaching the device of the L-shaped fixture rectangular, the best separation distance can be set by sliding the device back and forth.
Since the hole 24 attached to the axle 27 is similarly rectangular, it can be moved up and down, and can be mounted on bicycles having different wheel diameters. In addition, since the inclination of the device can be set freely when mounted on the axle 27, the irradiation angle of the light emitting element can be adjusted.

それでは発電と発光の原理を詳しく説明する。［図−１］に示すとおり、前記装置は前記自転車の前記車輪の車軸２７に装着され、スポーク２６と近接する関係にある。この状態において前記車輪が回転すると、間近に位置する前記装置とスポーク２６が交差する。この時、前記装置内の回転軸を持つ磁石１０がスポーク２６を一瞬であるが吸引する。複数本あるスポーク２６と回転軸を持つ磁石１０は断続的に交差する。この時、両者の間に磁気エネルギーが断続的に発生するので回転軸を持つ磁石は可動し続ける。Now, the principle of power generation and light emission will be explained in detail. As shown in FIG. 1, the device is mounted on the wheel axle 27 of the bicycle and is in close proximity to the spokes 26. When the wheel rotates in this state, the spoke 26 intersects with the device located nearby. At this time, the magnet 10 having the rotating shaft in the apparatus attracts the spoke 26 for a moment. The plurality of spokes 26 and the magnet 10 having the rotation axis intersect intermittently. At this time, since magnetic energy is intermittently generated between the two, the magnet having the rotating shaft continues to move.

本発明の特徴として、回転軸を持つ磁石１０を可動させる手段として補助磁石１４を使用しているところにある。前記車輪が静止状態にあるとき回転軸を持つ磁石１０は、筒内の後方に位置する補助磁石１４と異極状態にあり、互いに引き合っているので静止している。しかし、前記車輪が回転すると回転軸を持つ磁石１０はスポーク２６と交差するので、瞬間ではあるがスポーク２６を吸引して動く。これにより、動く前に異極同士にあった補助磁石１４と回転軸を持つ磁石１０は同極同士になり反発し合う。反発と吸引を繰り返す回転軸を持つ磁石１０は勢いを増し鋭い動きを繰り返すのである。As a feature of the present invention, the auxiliary magnet 14 is used as means for moving the magnet 10 having the rotation shaft. When the wheel is in a stationary state, the magnet 10 having the rotation shaft is in a different polarity from the auxiliary magnet 14 located in the rear of the cylinder and is stationary because it attracts each other. However, when the wheel rotates, the magnet 10 having the rotation axis intersects with the spokes 26, so that the spokes 26 are attracted and moved instantaneously. As a result, the auxiliary magnet 14 and the magnet 10 having the rotating shaft that were in different polarities before moving are reciprocal with each other. The magnet 10 having a rotating shaft that repeats repulsion and attraction increases its momentum and repeats a sharp movement.

鋭い動きをする回転軸を持つ磁石１０は間近にある誘導コイル１１ａや１１ｂに対して磁束を速く切ることになる。この結果、誘導コイル１１ａや１１ｂの両端には発光素子が発光するのに十分な起電力が生まれる。ここに発生した起電力で発光素子１２ａや１２ｂは発光し、自転車の安全装置としての役割を果たしてくれる。The magnet 10 having a rotating shaft that moves sharply cuts the magnetic flux quickly relative to the nearby induction coils 11a and 11b. As a result, an electromotive force sufficient for the light emitting element to emit light is generated at both ends of the induction coils 11a and 11b. The light emitting elements 12a and 12b emit light by the electromotive force generated here, and serve as a bicycle safety device.

前記車輪の回転が速すぎるとスポーク２６と回転軸を持つ磁石１０の交差時間が減少することで回転軸を持つ磁石１０の可動が小さくなり起電力が小さくなってしまうことが考えられるが、補助磁石１４の働きにより解消される。本発明はこの補助磁石１４が果たす役割に大きな特徴を持つ。一般的に自転車に乗り夜間走行する際にスピードを出すことは考えられないので、前記車輪の回転が速すぎる事による弊害はほとんどないと思われる。If the rotation of the wheel is too fast, the crossing time between the spoke 26 and the magnet 10 having the rotation axis may be reduced, so that the movement of the magnet 10 having the rotation axis is reduced and the electromotive force is reduced. It is eliminated by the action of the magnet 14. The present invention has a great feature in the role played by the auxiliary magnet 14. Generally, it is impossible to increase the speed when riding a bicycle at night, so it seems that there is almost no adverse effect caused by the rotation of the wheel being too fast.

回転軸を持つ磁石１０が可動するときに、摩擦抵抗を減少させるためにベアリング１５を装着して回転軸を持つ磁石１０の鋭い動きを可能にした。回転軸を持つ磁石１０の動きが鋭くなれば間近に位置する誘導コイルに対し磁束を速く切ることになり、発光素子の輝きを大きくしてくれる。回転軸を持つ磁石の摩擦抵抗を減少させる物であればベアリング１５に変わる物であっても良い。When the magnet 10 having the rotation axis is moved, a bearing 15 is mounted to reduce the frictional resistance, thereby enabling the magnet 10 having the rotation axis to move sharply. If the movement of the magnet 10 having the rotation axis becomes sharp, the magnetic flux is quickly cut off to the induction coil located nearby, and the brightness of the light emitting element is increased. As long as it reduces the frictional resistance of the magnet having the rotating shaft, it may be replaced with the bearing 15.

前記装置は自転車のスポーク２６を利用するものであるから、スポーク２６の間近に設置する場合、前後車輪のどの位置に設置しても良い。又、自転車以外の物に取り付けて発電することも可能であり他の分野での活用も考えられるSince the apparatus uses the spoke 26 of the bicycle, when it is installed close to the spoke 26, it may be installed at any position on the front and rear wheels. It is also possible to generate electricity by attaching it to something other than a bicycle, and it can be used in other fields.

［図−３］［図−４］に示すように、誘導コイル１１ｂは回転軸を持つ磁石１０の左右のいずれかの位置に取り付ける手段もある。また、前記筒の周上に一つ、回転軸を持つ磁石の左右の位置に一つづつと複数設置する方法もある。これにより、いずれかひとつの誘導コイルを利用して充電回路を設けることが出来、静止状態での発光が可能となる。
また、残りの誘導コイルを利用して色の異なる発光素子を装置内で発光させることもできるのでより目立つ効果が得られる。[FIG. 3] As shown in [FIG. 4], the induction coil 11b also has means for attaching to the left or right position of the magnet 10 having the rotation axis. There is also a method of installing a plurality of magnets, one on the circumference of the cylinder, one on each side of the magnet having a rotation axis. Thereby, a charging circuit can be provided using any one induction coil, and light emission in a stationary state is possible.
Further, since the light emitting elements having different colors can be caused to emit light in the apparatus using the remaining induction coils, a more conspicuous effect can be obtained.

また、前記回転軸を持つ磁石１０が何らかの異常により可動しなくなってしまう場合に備えて、スポーク２６に緊急対策用として磁石を取りつけ、装置内の発電が停止した場合、装置内の誘導コイル１１ａや１１ｂに対し磁束を切ることで発電する手段を用いることも可能である。しかし、本発明に関わる課題として取り上げたが前記磁石が前記スポーク２６から離脱する現象が発生しても、回転軸を持つ磁石１０が異常を来さなければ問題はない。あくまでも非常時の対策としての使用を考えている。Further, in preparation for the case where the magnet 10 having the rotating shaft becomes unable to move due to some abnormality, when the magnet is attached to the spoke 26 as an emergency measure and the power generation in the apparatus is stopped, the induction coil 11a in the apparatus It is also possible to use means for generating electricity by cutting the magnetic flux with respect to 11b. However, although it was taken up as a problem related to the present invention, there is no problem even if the phenomenon that the magnet is detached from the spoke 26 occurs if the magnet 10 having the rotating shaft does not become abnormal. It is considered to be used as an emergency measure.
