五、新型說明： 【新型所屬之技術領域】 本創作係有關振動型電磁發電機，例如，在以複數個 電磁線圈所構成之發電線圈中，藉由於長度方向被磁化之 至少一個磁鐵的振動而進行發電。 【先前技術】 近年來’由於手機及遊樂機等之攜帶電子機器的普及 進展，內裝在該等的2次電池的量逐漸增多。又，隨著無 線技術的發展’由微小電力收送信號之 RFID(Radio Frequency IDentification)的應用漸廣泛。尤其具有電源之 有源RFID，也可通信數百公尺以上。因此，牧場之牛、馬 等的健康管理，和學童上下學時之安全管理等的應用被賦 予高度期待。 另一方面，爲了地球環境的維持改善，盡可能環境負 擔少的電池也活躍地被進行硏究開發。其中，將通常無意 識且浪費地被消費之能量轉換成電能、充電、再利用此電 能作爲攜帶機器等的電源被廣泛地思考著。 在專利文獻1，揭示有關透過從外部加以振動而發電 的振動型電磁發電機。在此，參照第11圖說明關於振動型 電磁發電機100的構成例。振動型電磁發電機100,係具備 由非磁性材料所形成之管1 02，與被收納在管1 02而於長度 方向磁化之棒狀的可動磁鐵101。在管102的中央部，形成 發電線圈103。在管102的兩端部，以與可動磁鐵101之極 性相同的極性成對向的狀態，設置有磁鐵104a、104b。因 M418485 此，可動磁鐵101振動時，防止可動磁鐵101與 兩晴部接觸。 在專利文獻2，揭示有關於透過從外部加以 電’用所得到之電力發光之備有振動型電磁發電 筒。在此，參照第12圖說明關於手電筒110的構 電筒110，係具備：由非磁性材料所形成之管112 納在管112並於長度方向磁化之棒狀的可動磁鐵 112的兩端部，設置有壓縮彈簧114a、114b。藉 彈簧114a、114b之作用，防止可動磁鐵ill與管 端部接觸。在管112的中央部形成電磁線圈112 的內部透過可動磁鐵111的振動，由電磁線圈1: 壓，使LED115發光。透過此發光，LED115發光 係由透鏡1 1 6擴散，而照射於對象物。 專利文獻1 :日本專利特開2002 - 28 1 727號 專利文獻2 :美國專利第59757 1 4號說明書 【新型内容】 可是，在專利文獻1所揭示之技術，則除了 接有用之磁鐵外尙需要配置2個磁鐵在管的兩端 電磁發電機，一般被要求盡可能以小的尺寸狀態 的發電電力。因此’有需要高的磁通密度。如此 之成本占整體成本的比率較高。所以，以往的振 發電機100，在成本方面係處於較不利。又，由於 而使振動型電磁發電機的重量增加，例如，有藉 進行發電時疲勞變大的問題。 管102的 振動而發 機的手電 成例。手 ,;與被收 1 1 1。在管 由此壓縮 1 1 2的兩 。管 1 1 2 [3產生電 之光線， 公報 對發電直 部。此種 ，獲得大 ，則磁鐵 動型電磁 多用磁鐵 由手操作 M418485 又，由於磁鐵之彈回力係不同於藉由彈簧之彈回力， 彈回力並不與可動磁鐵的移動距離成比例。因此，會.顯示 與藉由可動磁鐵的質量與螺旋彈簧的彈簧常數所決定的共 振振動會有相異的舉動，也會產生可動磁鐵之振動不能長 時間持續的問題。結果，藉由磁鐵之彈回力無法有效地轉 換成振動運動，並不具有可以提高發電力的作用。 又，在專利文獻2所揭示之技術，若於手電筒110施 加振動時，可動磁鐵111會暫時從螺旋彈簧離開或衝碰。 因此，可動磁鐵與螺旋彈簧，無法建構成穩定的共振系， 無法提高發電效率。又，因爲可動磁鐵與螺旋彈簧衝碰之 際會發生衝碰聲音，所以對使用者會形成刺耳。再者，一 般此種發電機，當可動磁鐵通過發電線圈時之速度，有助 於發電（輸出電壓）的大小。由此，爲了獲得更多的發電 有必要給與更激烈的振動，所以可動磁鐵與螺旋彈簧透過 激烈的衝突使螺旋彈簧容易破損。 本創作係有鑒於此狀况而著手者，以提供建構成穩定 之共振系同時使螺旋彈簧不易破損之振動型電磁發電機爲 目的。 本創作之振動型電磁發電機，其具備：以非磁性材料 所形成之中空管；被捲繞在管的周圍之至少一個發電線圈 :至少由一個磁鐵所形成而被配置在管內的可動磁鐵；被 固定在管的至少一端，並將可動磁鐵可振動地支撐在發電 線圈之捲軸方向而可伸縮的彈性體；限制可動磁鐵之振動 的停止器。停止器被形成在管之至少一端，而停止器與可 M418485 動磁鐵接觸的位置，若以管之端部爲起點時，係位於比彈 Λ 性體收縮最大時之長度更長的位置。 * 透過此種構成，使用彈性體構成穩定之共振系的狀態 下，對收縮最大的彈性體不會附加不要的應力。因此，可 獲得即使長期使用彈性體也不會破損且可發生穩定的共振 振動之振動型電磁發電機。 根據本創作時，透過用彈性體支撐可動磁鐵，而可.獲 Φ 得建構成穩定的共振系之振動型電磁發電機。又，可動磁 鐵超越既定的振幅而振動時，因爲可動磁鐵的振動會受到 停止器的限制，彈性體不會施加多餘的應力，而可防止彈 性體的破損。因此，對於振動型電磁發電機，可抑制維修 的頻率，而且振動型電磁發電機可經過長期具有發電的效 果。又，作爲彈性體因可使用螺旋彈簧，可降低構件成本 ，同時可實現振動型電磁發電機之輕量化。 【實施方式】 φ 創作之最佳實施形態 以下，參照第1圖至第6圖說明有關本創作之第1實 施形態。在本實施之形態例，係適用有關將長度方向磁化 之複數f圓筒形的磁鐵，於複數個電磁線圈中振動或移動 而發電之振動型電磁發電機1爲例加以說明。 首先，參照第1圖之截面圖說明有關本例之振動型電 磁發電機1的構成例。振動型電磁發電機1係由：可動磁 鐵3 ;與3個電磁線圈（第1電磁線圈4a〜第3電磁線圈4c )所構成。3個電磁線圈，係捲附在中空管2之外周所構 M418485 ，於 成。 慮加 配置 磁線 、反 線圈 構成 鐵（ 度方 的磁 反10 構成 之磁 張力 —方 磁鐵 賛5 b 依掛 成。透過可動磁鐵3在管2的內部直線往復運動/振動 ' 3個電磁線圈會產生電壓。管2係由非磁性材料所形 •管2的材質雖亦可爲金屬等的非磁性體材料，但若考 工性等則以塑膠等的合成樹脂製造較佳。 相鄰之3個電磁線圈，係隔著既定的間隔狀態而 ，由極性相反之複數個電磁線圈串列連接所構成。電 圈的捲繞方向，係將各相鄰之電磁線圈相互反向的正 φ '正方向。在以下的說明，係將串列連接之第1電磁 4a〜第3電磁線圈4c，稱爲發電線圈9。在管2至少建 1個發電線圈9。 可動磁鐵3，係由同極性對向而接合之複數個磁 例如，鈸磁鐵）所構成。本例之可動磁鐵3，係將長 向磁化之相同長度的2個磁鐵3a、3b，隔著既定厚度 鐵隔板1 0之後，把同極性相向接合成一體。磁鐵隔1 的材質，係磁性體及非磁性體中任一個均可。又，建 φ 可動磁鐵3之磁鐵至少1個即可。 在可動磁鐵3之一方的端部，被形成保護磁鐵3a 鐵端部構件8a。在磁鐵端部構件8a鑽有細孔用以安裝 彈簧之第1螺旋彈簧5a。同樣地，在可動磁鐵3之另 的端部，形成有磁鐵端部構件8b用以保護磁鐵3b。在 端部構件8b鑽有細孔用以安裝張力彈簧之第2螺旋彈 。但，亦可把磁鐵端部構件8a、8b作成鈎等的形狀， 上第1螺旋彈簧5a與第2螺旋彈簧5b的方式而安裝。 如此’在振動型電磁發電機1，透過第1螺旋彈簧5a M418485 與第2螺旋彈簧5b將可動磁鐵3朝發電線圈9的捲軸方向 * 振動地支撐。 •在管2的兩端部嵌上由樹脂等所形成的第1端構件7a 與第2端構件7b，用以防止可動磁鐵3的飛出。第1端構 件7a與第2端構件7b的形狀相同，分別形成固定部用以 固定第1螺旋彈簧5a與第2螺旋彈簧5b的端部。但，亦 可於第1端構件7a與第2端構件7b形成細孔或掛鈎等， φ 固定第1螺旋彈簧5a與第2螺旋彈簧5b的端部。 有關本創作之振動型電磁發電機1，如上述，相鄰之3 個電磁線圏，隔離既定的間隔之狀態下串列連接，同時其 捲繞方向係各相鄰之電磁線圈相互反向之正、反、正方向 所構成。因此，各個電磁線圈所發生之電壓成爲相位合成 的狀態，藉由合成可使輸出電壓增大。爲此，有必要使磁 鐵長度加上磁鐵間隔片的厚度之磁鐵間距，與線圏長加上 線圈間隔之線圈間距大致相等。再者，使電磁線圈的線圈 φ 長度短於磁鐵長度更佳。 第1螺旋彈簧5a與第2螺旋彈簧5b，係同樣彈簧常數 ，同樣自然長度的螺旋彈簧。但，依規格亦可改變各螺旋 彈簧之彈簧常數與自然長度。 • 在本實施形態之振動型電磁發電機1，係第1螺旋彈 簧5a與第2螺旋彈簧5b的各個成爲拉著可動磁鐵3的狀 態建構成振動系統。此時’若在振動型電磁發電機1施加 外力時’可動磁鐵3係由可動磁鐵3的質量，與第1螺旋 彈簧5a與第2螺旋彈簧5b的彈簧常數所決定的共振頻率 M418485 fr來振動。結果’可動磁鐵3的振動時間變長，可獲得長 ^ 時間之電壓。 •其次，參照第2A、2B圖說明關於緩和可動磁鐵對管2 之端部衝擊的停止器之構成例。在第2A、2B圖雖對第1 停止器6a予以說明，但第2停止器6b也是同樣的構成。 第2A圖係第1螺旋彈簧5a之伸長狀態圖。 第2B圖係第1螺旋彈簧5a縮最短之狀態圖。 φ 而且，將第1停止器6a與可動磁鐵3接觸之部位的寬 度11，較垂直於發電線圏9之捲軸方向之可動磁鐵3的截 面徑12小。即.，螺旋彈簧在伸縮運動時使停止器不會干涉 的方式，且因爲停止器形成與可動磁鐵3可確實地接觸， 超越既定的振幅而振動之可動磁鐵3，係在第1停止器6a 與可動磁鐡3接觸的位置時其振動會受到限制。 如第2A圖與第2B圖所示，以第1端構件7a爲起點之 第1停止器6a的高度1 Oa，設定比收縮最大的狀態之第1 φ 螺旋彈簧5a的高度10b更高。而且，可動磁鐵具有超越既 定振幅之運動能的狀態振動時，在第1停止器6 a的上端成 爲接觸/衝突。因此，透過第1停止器6a振幅會受到限制 。再者，第1停止器6a因爲由具有彈性之橡膠等的樹脂所 形成，所以亦可能緩和可動磁鐵3的衝擊。因此，儘管第 1螺旋彈簧5a爲收縮最大的狀態，可有效地抑制可動磁鐵 3會衝突而施加過剩的應力時發生之螺旋彈簧的破損。 在此，第1及/或第2的端構件7a、7b與停止器6a透 過一體成型而形成的情況時，期望選定硬質且具有彈性的 -10- M418485 橡膠及樹脂。欲選定如此材質，係爲了將振動的可動磁鐵 3確實地密封於管2的內部。又，因爲可動磁鐵3衝突到停 止器6a時對螺旋彈簧不會損傷，且可避免停止器本身的損 傷。 在此，參照第3圖至第6圖說明有關本創作之振動型 電磁發電機1的振動特性。 第3圖係將質量Μ的墜子15與彈簧常數k的螺旋彈簧 16組合所構成的振動系之示意圖。墜子15懸吊在螺旋彈簧 16時，螺旋彈簧16的恢復力，與賦予墜子15之重力在平 衡位置時墜子15即會靜止。此位置設爲零變位。墜子15 若加上外力時，墜子15開始單振動。此振動系統的共振頻 率fn可以次式（1)表示。 [第1式] fn = ( 1/2 π )(k/M) ..........(1) 可是，在第3圖並未顯示由於摩擦等的振動損失。但 ，在現實之振動系統存在著包含空氣的黏性阻力之摩擦阻 力，及振動體本身之內部摩擦等的各種損失。因此，隨著 時間的經過振幅會減振，共振頻率也會稍爲降低。 第4A、4B圖，係對第3圖所顯示之振動系，表示施加 與此振動系的共振頻率frl相等之頻率的外力，作爲正常 振動中的情况，迅速將外力變爲零之後不久的振幅之時間 變化例。 第4A圖係振動系之損失較少的情況。 第4B圖係振動系之損失稍大的情況。 -11 -

New type of description: [Technical field to which the new type belongs] The present invention relates to a vibrating electromagnetic generator, for example, in a power generating coil composed of a plurality of electromagnetic coils, by vibration of at least one magnet magnetized in the longitudinal direction Power generation. [Prior Art] In recent years, the number of secondary batteries incorporated in these devices has gradually increased due to the spread of portable electronic devices such as mobile phones and amusement machines. Moreover, with the development of wireless technology, the application of RFID (Radio Frequency IDentification) by small power transmission has become widespread. In particular, active RFID with power supply can communicate for hundreds of meters or more. Therefore, the application of the health management of cattle and horses in the pastures, and the safety management of school children when they go to school are highly expected. On the other hand, in order to improve the maintenance of the global environment, batteries with as little environmental burden as possible are actively being developed. Among them, it is widely considered that a power that is usually unconsciously and wastefully converted into electric energy, charged, and reused as a power source for carrying a machine or the like is widely considered. Patent Document 1 discloses a vibration type electromagnetic power generator that generates electric power by vibration from the outside. Here, a configuration example of the vibration type electromagnetic power generator 100 will be described with reference to Fig. 11 . The vibrating electromagnetic generator 100 includes a tube 102 formed of a non-magnetic material and a rod-shaped movable magnet 101 that is accommodated in the tube 102 and magnetized in the longitudinal direction. At the central portion of the tube 102, a power generating coil 103 is formed. Magnets 104a and 104b are provided at both end portions of the tube 102 in a state in which the same polarity as that of the movable magnet 101 is opposed. When the movable magnet 101 vibrates due to M418485, the movable magnet 101 is prevented from coming into contact with the two clear portions. Patent Document 2 discloses a vibration type electromagnetic power generation unit that emits light by transmitting electric power obtained from the outside. Here, the structure of the flashlight 110 of the flashlight 110 is provided with both ends of a rod-shaped movable magnet 112 which is formed of a non-magnetic material and which is magnetized in the tube 112 and magnetized in the longitudinal direction. There are compression springs 114a, 114b. The movable magnet ill is prevented from coming into contact with the end portion of the tube by the action of the springs 114a, 114b. The inside of the electromagnetic coil 112 is formed in the central portion of the tube 112 to transmit vibration of the movable magnet 111, and the electromagnetic coil 1 is pressed to cause the LED 115 to emit light. Through this light emission, the LED 115 emits light by the lens 116 and is irradiated onto the object. Patent Document 1: Japanese Patent Laid-Open Publication No. 2002-28 No. 727 Patent Document 2: U.S. Patent No. 59,757, 1-4, the disclosure of which is incorporated herein by reference. An electromagnetic generator is provided with two magnets at both ends of the tube, and it is generally required to generate electricity in a small size state as much as possible. Therefore, there is a need for a high magnetic flux density. Such a ratio of costs to overall costs is higher. Therefore, the conventional vibrating generator 100 is disadvantageous in terms of cost. Further, the weight of the vibration type electromagnetic power generator is increased, and for example, there is a problem that fatigue is increased when power generation is performed. A flashlight that is activated by the vibration of the tube 102. Hand , ; and received 1 1 1 . The tube is thus compressed by 1 1 2 of two. Tube 1 1 2 [3 produces electricity light, bulletin to power generation straight. In this way, if the magnet is large, the magnet is electromagnetic. The multi-purpose magnet is operated by the hand. M418485 In addition, since the rebound force of the magnet is different from the spring return force by the spring, the rebound force is not proportional to the moving distance of the movable magnet. Therefore, the display and the resonance vibration determined by the mass of the movable magnet and the spring constant of the coil spring may be different, and the vibration of the movable magnet may not last for a long time. As a result, the repulsive force of the magnet cannot be effectively converted into a vibrating motion, and does not have an effect of improving the power generation. Further, in the technique disclosed in Patent Document 2, when the vibration is applied to the flashlight 110, the movable magnet 111 temporarily leaves or collides from the coil spring. Therefore, the movable magnet and the coil spring cannot be constructed to constitute a stable resonance system, and power generation efficiency cannot be improved. Further, since the movable magnet and the coil spring collide with each other, a collision sound is generated, so that the user is pierced. Furthermore, the speed of the generator, when the movable magnet passes through the power generating coil, contributes to the power generation (output voltage). Therefore, in order to obtain more power generation, it is necessary to give more intense vibration, so that the coil spring is easily broken by the intense collision between the movable magnet and the coil spring. In view of this situation, the author of this creation aims to provide a vibrating electromagnetic generator that constitutes a stable resonance system and which is difficult to break the coil spring. The vibrating electromagnetic generator of the present invention comprises: a hollow tube formed of a non-magnetic material; and at least one power generating coil wound around the tube: movable by at least one magnet and disposed in the tube a magnet; an elastic body fixed to at least one end of the tube and rotatably supporting the movable magnet in a reel direction of the power generating coil; and a stopper for restricting vibration of the movable magnet. The stopper is formed at at least one end of the tube, and the position where the stopper is in contact with the movable magnet of the M418485 is located at a position longer than the length at which the elastic body contracts most when the end portion of the tube is used as a starting point. * With this configuration, in the state where the elastic body is used to form a stable resonance system, unnecessary stress is not added to the elastic body having the largest shrinkage. Therefore, it is possible to obtain a vibration type electromagnetic generator which does not break even when the elastomer is used for a long period of time and which can generate stable resonance vibration. According to the present creation, by using the elastic body to support the movable magnet, it is possible to obtain a vibration type electromagnetic generator which constitutes a stable resonance system. Further, when the movable magnet vibrates beyond a predetermined amplitude, the vibration of the movable magnet is restricted by the stopper, and the elastic body does not apply excessive stress, and the elastic body can be prevented from being damaged. Therefore, for the vibration type electromagnetic generator, the frequency of maintenance can be suppressed, and the vibration type electromagnetic generator can have the effect of generating electricity over a long period of time. Further, since the coil spring can be used as the elastic body, the component cost can be reduced, and the weight of the vibration type electromagnetic generator can be reduced. [Embodiment] Optimum embodiment of φ creation Hereinafter, a first embodiment of the present invention will be described with reference to Figs. 1 to 6 . In the embodiment of the present embodiment, a vibrating electromagnetic generator 1 in which a plurality of f-cylindrical magnets magnetized in the longitudinal direction are vibrated or moved in a plurality of electromagnetic coils to generate electric power is applied as an example. First, a configuration example of the vibration type electromagnetic generator 1 according to the present embodiment will be described with reference to a cross-sectional view of Fig. 1. The vibration type electromagnetic generator 1 is composed of a movable magnet 3 and three electromagnetic coils (first electromagnetic coil 4a to third electromagnetic coil 4c). Three electromagnetic coils are attached to the outer circumference of the hollow tube 2 to form M418485. Considering the arrangement of the magnetic wire and the reverse coil to form the iron (the magnetic tension formed by the magnetic reverse 10 of the square side - the square magnet 5 5 is hung. The movable magnet 3 reciprocates/vibrates inside the tube 2 through the movable magnet 3] 3 electromagnetic coils The tube 2 is formed of a non-magnetic material. The material of the tube 2 may be a non-magnetic material such as metal. However, it is preferably made of a synthetic resin such as plastic if the workability is the same. The three electromagnetic coils are connected by a plurality of electromagnetic coils of opposite polarities in a predetermined interval state. The winding direction of the electric coil is a positive φ ' of the adjacent electromagnetic coils being reversed from each other. In the following description, the first electromagnetic 4a to the third electromagnetic coil 4c connected in series are referred to as a power generating coil 9. At least one power generating coil 9 is built in the tube 2. The movable magnet 3 is of the same polarity The plurality of magnets that are joined to each other, for example, neodymium magnets. In the movable magnet 3 of the present embodiment, the two magnets 3a and 3b of the same length that are magnetized in the longitudinal direction are joined to each other with the same polarity interposed therebetween, with a predetermined thickness of the iron separator 10 interposed therebetween. The material of the magnet spacer 1 can be either a magnetic body or a non-magnetic material. Further, at least one magnet of the φ movable magnet 3 may be formed. At one end of the movable magnet 3, the protective end portion 8a of the protective magnet 3a is formed. A first coil spring 5a having a hole for mounting a spring is drilled in the magnet end member 8a. Similarly, at the other end of the movable magnet 3, a magnet end member 8b is formed to protect the magnet 3b. A second hole is drilled in the end member 8b to mount a tension spring. However, the magnet end members 8a and 8b may be formed in the shape of a hook or the like, and the first coil spring 5a and the second coil spring 5b may be attached. In the vibrating electromagnetic generator 1, the movable magnet 3 is vibrated and supported in the reel direction * of the power generating coil 9 through the first coil springs 5a to M418485 and the second coil spring 5b. • The first end member 7a and the second end member 7b formed of resin or the like are fitted to both ends of the tube 2 to prevent the movable magnet 3 from flying out. The first end member 7a has the same shape as the second end member 7b, and each has a fixing portion for fixing the end portions of the first coil spring 5a and the second coil spring 5b. However, a hole or a hook or the like may be formed in the first end member 7a and the second end member 7b, and the end portions of the first coil spring 5a and the second coil spring 5b may be fixed by φ. In the vibration type electromagnetic generator 1 of the present invention, as described above, the adjacent three electromagnetic coils are connected in series in a state of being separated by a predetermined interval, and the winding direction thereof is opposite to each other of the adjacent electromagnetic coils. It is composed of positive, negative and positive directions. Therefore, the voltage generated by each electromagnetic coil becomes a state of phase synthesis, and the output voltage can be increased by synthesis. For this reason, it is necessary to make the magnet pitch plus the magnet pitch of the thickness of the magnet spacer substantially equal to the coil pitch and the coil pitch of the coil. Further, it is preferable to make the length of the coil φ of the electromagnetic coil shorter than the length of the magnet. The first coil spring 5a and the second coil spring 5b are coil springs having the same spring constant and the same natural length. However, the spring constant and natural length of each helical spring can also be changed depending on the specifications. In the vibration type electromagnetic generator 1 of the present embodiment, each of the first coil spring 5a and the second coil spring 5b is configured to be in a state in which the movable magnet 3 is pulled. At this time, when the external force is applied to the vibration type electromagnetic generator 1, the movable magnet 3 vibrates by the mass of the movable magnet 3 and the resonance frequency M418485 fr determined by the spring constants of the first coil spring 5a and the second coil spring 5b. . As a result, the vibration time of the movable magnet 3 becomes long, and a voltage of a long time can be obtained. • Next, a configuration example of a stopper for mitigating the impact of the movable magnet on the end portion of the tube 2 will be described with reference to FIGS. 2A and 2B. Although the first stopper 6a is described in the second and second drawings, the second stopper 6b has the same configuration. Fig. 2A is a view showing an extended state of the first coil spring 5a. Fig. 2B is a state diagram in which the first coil spring 5a is shortened to the shortest. Further, the width 11 of the portion where the first stopper 6a is in contact with the movable magnet 3 is smaller than the cross-sectional diameter 12 of the movable magnet 3 perpendicular to the direction of the winding of the power generating wire 圏9. In other words, the coil spring does not interfere with the stopper during the telescopic movement, and since the stopper forms a positive contact with the movable magnet 3, the movable magnet 3 that vibrates beyond the predetermined amplitude is attached to the first stopper 6a. The vibration is limited when it is in contact with the movable magnetic head 3. As shown in Figs. 2A and 2B, the height 1 Oa of the first stopper 6a starting from the first end member 7a is set to be higher than the height 10b of the first φ coil spring 5a in a state where the contraction is maximum. Further, when the movable magnet has a state vibration that exceeds the kinetic energy of a predetermined amplitude, the upper end of the first stopper 6a becomes a contact/collision. Therefore, the amplitude of the first stopper 6a is limited. Further, since the first stopper 6a is formed of a resin such as elastic rubber, the impact of the movable magnet 3 may be alleviated. Therefore, although the first coil spring 5a is in the state of maximum contraction, it is possible to effectively suppress the breakage of the coil spring which occurs when the movable magnet 3 collides and excessive stress is applied. Here, when the first and/or second end members 7a and 7b and the stopper 6a are integrally formed, it is desirable to select a rigid and elastic 10- 10418485 rubber and resin. The material is selected in order to reliably seal the vibrating movable magnet 3 inside the tube 2. Further, since the movable magnet 3 collides with the stopper 6a, the coil spring is not damaged, and the damage of the stopper itself can be avoided. Here, the vibration characteristics of the vibration type electromagnetic generator 1 according to the present invention will be described with reference to Figs. 3 to 6 . Fig. 3 is a schematic view showing a vibration system in which a weight 15 and a coil spring 16 having a spring constant k are combined. When the sinker 15 is suspended from the coil spring 16, the restoring force of the coil spring 16 and the weight imparted to the sinker 15 are in a balanced position, and the sinker 15 is stationary. This position is set to zero displacement. Pendant 15 When an external force is applied, the sinker 15 starts to vibrate. The resonance frequency fn of this vibration system can be expressed by the following formula (1). [Formula 1] fn = ( 1/2 π ) (k / M) (1) However, the vibration loss due to friction or the like is not shown in FIG. However, in the actual vibration system, there are various kinds of losses including the frictional resistance of the viscous resistance of the air and the internal friction of the vibrating body itself. Therefore, as the amplitude of the time passes, the resonance frequency is slightly reduced. 4A and 4B, the vibration system shown in Fig. 3 shows an external force applied at a frequency equal to the resonance frequency frl of the vibration system, and as a normal vibration, the amplitude immediately after the external force becomes zero Time variation example. Fig. 4A shows a case where the loss of the vibration system is small. Fig. 4B shows a case where the loss of the vibration system is slightly large. -11 - M418485 As shown in Fig. 4B, when the loss of the vibration system is large, the rapid force becomes zero. The vibration is rapidly reduced. That is, as shown in Fig. 4A, when the loss of the system is reduced as much as possible, the voltage of the movable magnet is long, so that the voltage can be obtained for a long time. Figs. 5A and 5B show the amplitude of the sinker 15 when the vibration force is applied to the vibration system shown in Fig. 3. The pulsating impact force contains a wide frequency component and also contains the resonance frequency component of φ. Therefore, the effect of the resonance frequency component is excited. As a result, the sinker will have less loss of the vibration system of the Sth 5A system as shown in Figs. 5A and 5B. Fig. 5B shows a case where the loss of the vibration system is slightly large. As shown in Figures 5A and 5B, the vibration of the vibration system will continue to vibrate. On the other hand, if the loss is large, the vibration is rapidly reduced, and the amplitude is also increased in the case of loss. Fig. 6 is a schematic view showing a vibration system in which a weighted pendant 15 is suspended by two φ springs 17, 18 in the vertical direction. The spring constants of the coil springs are kl and k2, respectively. In Fig. 6, the downward direction is set to the reciprocal direction. Because the gravity of the sinker is applied, the position of the upper coil spring 17 by the sinker 15 becomes a stationary point zero. The vibration of the sinker 15 is centered on zero. The resonance frequency fr2 of the vibration system is expressed by (2). [Formula 2] fr2 = l /2 π Vki + k2/M (2) From the equation (2), it is known that the resonance frequency fr2 is due to the coil spring 17 It will change the vibrating system of the vibrating system. Long time. Therefore, the static point of the force of the helical springs 17, 18 is increased by the sum of the spring -12-M418485 constant kl of the secondary spring and the spring constant k2 of the coil spring 18. Therefore, if the vibration is applied to the sinker 15, the number of vibrations of the sinker 15 will increase in a given period of time. According to the vibration type electromagnetic generator 1 of the first embodiment described above, when the movable magnet 3 vibrates beyond a predetermined amplitude, the vibration of the movable magnet 3 is restricted by the first stopper 6a and the second stopper 6b. . Therefore, the elastomer does not add excessive stress, and the φ of the elastomer can be prevented from being damaged. As a result, the vibration type electromagnetic generator 1 can suppress the maintenance frequency such as repair of parts, and the vibration type electromagnetic generator 1 has an effect of generating power over a long period of time. Further, the vibration type electromagnetic generator 1 can construct a resonance system whose spring constant is determined by the spring constant of the first coil spring 5a and the second coil spring 5b due to the mass of the movable magnet 3. Further, the material of the tube 2 is selected so that the friction coefficient between the movable magnet and the movable magnet is reduced, and the vibration of the movable magnet 3 is not damped for a long period of time. Thus, there is an effect that the electrical efficiency of the vibration of the vibration type electromagnetic generator 1 can be improved. Further, as shown in the first embodiment, the first and second coil springs 5a and 5b are disposed from the both ends of the movable magnet 3 to both ends of the tube 2 to the first and second end members 7a and 7b. . With this configuration, the vibrating electromagnetic generator 1 can obtain an efficient power generation effect in any direction. Further, by selecting the spring constant of the first coil spring 5a and the second coil spring 5b for the mass of the movable magnet 3 measured in advance, the resonance frequency can be arbitrarily adjusted. Therefore, the effect of the vibration type electromagnetic generator 1 having high power generation efficiency suitable for the application can be obtained. -13- M418485 When the vibrating electromagnetic generator 1 is used, the weak vibration can be efficiently converted into a linear reciprocating motion of the movable magnet 3. Therefore, the vibration type electromagnetic generator 1 is in a state in which the direction of gravity is parallel, and the direction in which the vibration type electromagnetic generator 1 is set is constant. For example, for the safe navigation of a marine ship, power generation is generated by the up and down movement of the wave. A light-emitting buoy or the like can be said to be suitable as a generator. In addition, even if a strong vibration is generated by the stopper, the vibration of the vibration type electromagnetic generator is less likely to be applied to the bicycle shelf or the seat, and the suspension device of the automobile. Further, when the pulsating impact force is applied to the vibration type electromagnetic generator 1, the movable magnet 3 is excited by the component of the self resonance frequency contained in the impact force. Therefore, the frequency of the external force is not necessarily the effect of being attached to the resonance frequency of the vibration type electromagnetic generator 1. In addition, it can solve the problem that the vibration-type electromagnetic generator becomes a problem by using a magnet for bounce, which causes an increase in cost and a resonance system imbalance, and the spring is not contacted at the end face of the φ non-magnetic tube. The noise generated when the movable magnet is placed in a state and the effect that the power generation efficiency is lowered as the vibration efficiency is deteriorated. 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 Figs. 7A and 7B. It is to be noted that the same reference numerals are given to the parts of the first embodiment and the second and second aspects of the drawings, and the detailed description is omitted. Fig. 7A is a cross-sectional view showing the vibration type electromagnetic generator 30. Fig. 7B shows an example of the configuration of the stopper. -14- M418485 As shown in Fig. 7A, the first coil spring 32a and the second coil spring 32b are both compression springs. The first coil spring 32a and the second coil spring 32b* are in contact with both end portions of the movable magnet 3, and the movable magnet 3 is vibratedly supported in the spool direction of the power generating coil 9. In this case, since the first and second coil springs 32a and 32b are supported by compressing the movable magnet 3, it is not necessary to use the magnet end members 8a and 8b in the first embodiment, and the configuration can be simplified. φ Further, four projections are formed on the inner wall at a position near both ends of the tube 2. These projections serve as a first stopper 31a and a second stopper 31b, respectively. When the first stopper 31a and the second stopper 31b are in contact with the movable magnet 3, when the end portions 7a and 7b of the tube 2 are used as the starting point, the first coil spring 32a and the second coil spring 32 2b are contracted the most. The longer the length of the position. Further, the cross-sectional diameter of the movable magnet 3 in the direction perpendicular to the winding direction of the power generating coil 9 is such that the width of the portion where the first stopper 6a or the second stopper 6b contacts the movable magnet 3 is small. Therefore, the movable magnet 3 that exceeds the predetermined vibration of the vibration is limited in vibration at the position where the first stopper 6a or the second stopper 6b is in contact with the movable magnet 3. Further, in the case where the tube 2 and the stopper are integrally formed, when the tube 2 is formed into a cylindrical shape, the movable magnet cannot be sealed due to the protruding stopper. Therefore, the fitting of the tubular member which is formed separately from the longitudinal direction of the tube 2 is divided into two, and the tube is provided with a thread/coiled tube at the joint portion thereof in the center portion of the tube 2 and perpendicularly to the longitudinal direction. The member may be screwed together to explain its function and effect by focusing on the first stopper 31a. -15 - M418485 The width of the apex of the four protrusions of the first stopper 31a is wider than the winding radius of the first rotation spring 32a', that is, the expansion and contraction motion of the coil spring is made to make the stopper not interfere with the dimensional condition. And is fixed on the wall of the tube 2. Therefore, the expansion and contraction of the first coil spring 32a is not restricted by the i-th 31a. However, since the width of the apex of the four projections is narrower than the cross-sectional diameter of the movable magnet 3, the projections of the four projections can surely come into contact with the movable magnet 3. Therefore, the first coil spring φ is in contact with the vicinity of the four projections before the maximum contraction, and the vibration of the movable magnet 3 is restricted. As a result, the effect that the first coil springs 32a and the movable magnets 3 are excessively damaged by the first coil springs 32a in the state in which the contraction is maximized can be obtained, and the same effect can be obtained also in the second stoppers 31b. Further, in the vibrating electromagnetic generator 30, only the first coil spring and the second coil spring 3 2b are enclosed in the tube 2 to constitute a vibration system. Therefore, it is easy to construct a long-term vibration through a coil spring, and the effect of generating electricity is good. Further, the vibrating electromagnetic generator 30 of the second embodiment has four projections as the stoppers, but the number of the projections may be small or more than four. Further, the protruding portion is not limited to the shape shown in Fig. 7B. As long as the vibration of the movable magnet 3 beyond the appropriate amplitude can be restricted, the shape of the coil spring can be suppressed from the impact at the end and the unnecessary stress. Further, the vibration type electromagnetic generator 30' of the second embodiment has two compression springs. However, it is also possible to use only one compression spring. When this 1 screw is turned, the inner stop sets the point 32a vertex avoidance force. Also: 32a > - good rate, although shown in Figure 4, or any use of the situation -16 - M418485, the compression spring is placed in the gravity direction of the movable magnet 3 (lower side), while the magnet end member 8a and The one end member 7a is preferably fixed. Even if it is configured as such, appropriate power generation can be performed. Further, when the compression spring is used as the coil springs 32a' to 32b, the stopper is preferably provided on the inner diameter side of the coil spring. A configuration example of the vibration type electromagnetic power generator configured as above will be described with reference to Fig. 8. Further, in Fig. 8, the state φ of the stopper 33 of the first coil spring 32a is shown, but the stopper 33 of the second coil spring 32b has the same configuration. The movable magnet 3 is sealed to the first end member 34 of the tube 2, and is cylindrical, and a stopper 33 having a tapered surface is formed at the tip end. Further, the first coil spring 32a is provided in the first end member 34. On the other hand, the first coil spring 32a is vibrated by the stopper 33 without causing a positional movement. The movable magnet 3 that vibrates beyond a predetermined amplitude comes into contact with the top surface of the stopper 33, so that the vibration is restricted. However, when the top end of the stopper 33 is in contact with the movable magnet 3, the first end member 34 is located at a position longer than the length when the first coil spring 32a is φ. Therefore, the first helical spring 32a having the largest contraction does not apply excessive stress, and the effect of avoiding the damage of the first coil spring 32a can be obtained. Further, since the stopper is formed into a tapered shape, the expansion and contraction movement of the coil spring can be performed without interference. Further, in the second embodiment described above, when the inner circumferential diameter of the tube 2 is compressed by a coil spring (compression spring) in a state where the spring diameter of the coil spring is small, the coil spring is compressed in a warped state. In this state, in the worst case, it is expected that the -17-M418485 interference of the stopper will occur during the compression of the coil spring. Therefore, as a more preferable example, the spring diameter of the coil springs and 32b is slightly smaller than the inner circumference of the tube 2. By the fact that the compression spring is regularly compressed, the coil spring is not interfered by the stopper even when it is being retracted, and the function of the device can be sufficiently obtained. Next, a configuration example of the vibration type electromagnetic generator 40 according to the third embodiment of the present invention will be described with reference to Figs. 9A and 9B. In the ninth φ diagram, the same reference numerals are given to portions corresponding to those in the first embodiment and the second embodiment, and the detailed description is omitted. Fig. 9A is a cross-sectional view showing the vibration type electromagnetic generator 40. Fig. 9B shows a configuration example of a rod stopper. Holes are formed in the side of the tube 2 for inserting two rod-shaped stoppers. Two rod-shaped stoppers inserted into the holes are used as the second stopper and the second stopper 41b, respectively. The position where the first stopper 41a and the second stopper 41b are in contact with the movable magnet 3 is a position longer than the end portion of the tube 2 as the starting point φ is larger than when the first coil spring 5a and the second coil spring 5b are most contracted. Here, attention is paid to the first stopper 4 1 a to describe the two rod-shaped stoppers whose functions and effects are the first stopper 41a, which are composed of non-magnetic or metal, and are wound by the first coil spring 5a. A wider radius is fixed to the inner wall of the tube 2. Therefore, the expansion and contraction of the first coil spring 5a is not limited by the stopper 41a. However, the width of the two rod-shaped stoppers is narrower than the diameter of the cross-section of the iron 3. Therefore, the first coil spring 5a contracts the most movable magnet 3 in contact with the two rod-shaped stoppers, and restricts the movable magnetic force: 32a to stop the pressing, 9B 2A. When 4 1a is tied, the length. The width of the resin is affected by the vibration of the iron 3 -18 - M418485. As a result, it is possible to avoid the danger of the first coil spring 5a or the movable magnet 3 being damaged by the first coil spring 5a in a state where the contraction is maximized by the excessive stress. Further, the same configuration can be adopted for the second stopper 41b, and the same effect can be obtained. Further, in the vibration type electromagnetic generator 40 of the third embodiment, two rod-shaped stoppers are inserted as the stopper, but the number of the rod-shaped stoppers may be less than two or more than two. Further, the shape of the rod stopper is not limited to the shape as shown in Fig. 9B. For example, the cross-sectional shape of the rod stopper may also be polygonal or elliptical. The shape of the rod stopper can be any shape as long as it can restrict the vibration of the movable magnet 3 from exceeding an appropriate amplitude, or suppress the collision with the end portion and the unnecessary stress in the shape of the coil spring. Next, a configuration example of the vibration type electromagnetic power generator 50 according to the fourth embodiment of the present invention will be described with reference to Fig. 10. In the first embodiment, the same reference numerals are given to the portions corresponding to the first and second embodiments, and the description of the first embodiment and the second and second embodiments are omitted. In the vibration type electromagnetic power generator according to the first to third embodiments, the coil springs are disposed on both sides of the movable magnet 3. However, as in the present embodiment, a vibration system may be formed by the one coil spring and the movable magnet 3. In the second end member 51 of the tube 2, projections, hooks, pores, and the like for fixing the coil spring are not formed. Therefore, the second end member 51 has only the function of sealing the movable magnet 3 to the tube 2. In the vibration type electromagnetic generator 50, the movable magnet 3 is rotatably supported by the reel direction of the power generating coil 9 through the first coil spring 5a. -19- M418485 When an external force is applied to the vibration type electromagnetic generator 50, the movable magnet 3' vibrates. This vibration is a resonance vibration of the resonance frequency frl obtained by the above formula (1) by the mass of the movable magnet 3 and the spring constant of the first coil spring 5a. In the vibration type electromagnetic generator 50 shown in Fig. 10, only one coil spring is used. Therefore, there is an effect that the assembly of each member is easy. Further, the installation location of the vibration type electromagnetic generator 50 is suitable for the case where the installation direction of the generator is constant for the gravity ^. In other words, when a tension spring is used as the coil spring, the coil spring may be placed on the upper side in the direction of gravity in the direction of gravity, and the movable magnet may be suspended. On the other hand, when the coil spring is a compression spring, the coil spring may be disposed on the lower side in the gravity direction of the movable magnet, and the movable magnet may be configured to be lifted from the bottom to the top. Thus, the most appropriate method can be selected by the use and arrangement of the vibration type electromagnetic generator 50. Further, in any of the above configurations, the movable magnet, the end member, and the helical spring φ spring are preferably fixed by hooks or the like, and the vibration system of the coil spring can be sufficiently utilized. Moreover, the same effect as the vibration-type electromagnetic generator of the first to third embodiments using the two coil springs can be obtained. Further, in the first to fourth embodiments described above, the adjacent electromagnetic coils may be formed with a spacer, but may be formed of a member such as a resin. Further, a magnet spacer of a magnetic body and a non-magnetic material may be combined to constitute a movable magnet. Further, in the first to fourth embodiments described above, the shape of the tube and the movable magnet is a cylindrical shape, but a polygonal shape of a cross-sectional shape, an elliptical shape, or a combination of a curved line and a straight line may be employed. In this case, the cross-sectional shape of the electromagnetic coil and the magnet-20-M418485 spacer can be matched with the cross-sectional shape of the movable magnet. Further, in the first to fourth embodiments described above, in order to seal the movable magnet 3 to Although the first to the second end members are attached to the both ends of the tube 2 as the sealing member, the end portion of the tube 2 may be deformed and sealed by the movable magnet 3 by heat processing or the like. Further, each of the stopper groups shown in the first to fourth embodiments described above may be combined. φ Further, the stopper may be formed at least at one end of the tube 2 in accordance with the number of the coil springs. Therefore, in the case of using one coil spring, one stopper is sufficient, and the molding of the member becomes easy. Further, a magnet end member may be provided at an end portion of the movable magnet 3 on the side where the coil spring is disposed. At the end of the movable magnet 3, since the end portion of the coil spring comes into contact with each other, the magnet end member can be prevented from being damaged by the magnet end member. Further, the end portions of the magnet end member and the tube 2 may be joined by a coil spring. Further, a stopper is formed at both ends of the tube 2, and a coil spring φ spring is disposed from both ends of the movable magnet from both ends of the movable magnet 3 of the tube 2 to both ends of the tube 2. By doing so, the movable magnet 3 can be reliably supported, and there is no loss of vibration energy, and the vibration can be continued for a long time.
