Description
本考案は、特に楽に駆動され、且つ優れる発電効果を有する自転車用発電ハブに関するものである。 The present invention relates to a bicycle power generation hub that is particularly easily driven and has an excellent power generation effect.
夜間で自転車に乗る場合、危険を防止するために充分な照明が必要である。そこで、充分な照明を得るため、自転車に小型発電機又はバッテリーのような電力提供システムが装備されるが、該電力提供システムは使用期限を有する消耗品であるため、小型発電機が今よく使用されている。 When cycling at night, sufficient lighting is needed to prevent danger. Therefore, in order to obtain sufficient illumination, a bicycle is provided with a power supply system such as a small generator or a battery, but since the power supply system is a consumable item having a limited expiration date, the small generator is frequently used. Have been.
従来の小型発電機は設置スペースを節約するために、自転車のハブと一体に形成する構造を有し、ハブの内部における磁石とコイルの相対回転によって磁場の変化を発生することにより発電する。なお、前記従来のハブ式発電機は既に存在するものであるので、その内部における細かい部材の説明は省略し、磁場の変化を発生するための部材だけを説明する。 In order to save installation space, a conventional small generator has a structure integrally formed with a bicycle hub, and generates electric power by generating a change in a magnetic field by the relative rotation of a magnet and a coil inside the hub. Since the conventional hub-type generator already exists, a detailed description of the internal members will be omitted, and only members for generating a change in the magnetic field will be described.
図３に示すように、従来のハブ式発電機は、磁場の変化を発生するために、該ハブ式発電機におけるハブ本体の内周側に、互いに組み合わされる一対の爪座（３０）を有し、一対の爪座（３０）の内側には、外周側にコイル（不図示）を有する固定子（３１）が設けられ、該固定子（３１）の中央部にポール部材（３２）を挿入するため取付孔（３１０）が形成される。 As shown in FIG. 3, the conventional hub-type generator has a pair of claw seats (30) combined with each other on the inner peripheral side of the hub body in the hub-type generator in order to generate a magnetic field change. A stator (31) having a coil (not shown) on the outer peripheral side is provided inside the pair of claw seats (30), and a pole member (32) is inserted into the center of the stator (31). For this purpose, a mounting hole (310) is formed.
発電効果については、前記ポール部材（３２）が、車軸（不図示）をリング状に囲む構造であることが望ましいが、現在のポール部材（３２）の製造技術では、車軸をリング状に囲むことのできる構造を備えるポール部材（３２）の製造が困難である。従って、従来のポール部材（３２）は、複数枚のポールプレートを、車軸をできるだけリング状に囲むことができるように配置して形成し、固定子（３１）の中央部の取付孔（３１０）に挿入されている。 Regarding the power generation effect, it is desirable that the pole member (32) has a structure surrounding the axle (not shown) in a ring shape. However, according to the current manufacturing technology of the pole member (32), the axle is surrounded in a ring shape. It is difficult to manufacture a pole member (32) having a structure that can be used. Therefore, the conventional pole member (32) is formed by arranging a plurality of pole plates so as to surround the axle in a ring shape as much as possible, and mounting holes (310) in the center of the stator (31). Has been inserted.
又、前記従来の爪座（３０）は、ハブ本体が備えるリング状永久磁石の内部に収容される円形の金属プレートを有し、該金属プレートの周縁には、リング状永久磁石の極数と等しく、且つ、該リング状永久磁石と互いに磁気的に作用する爪部（３００）が突設されている。この爪部（３００）は磁場の変化を簡単に発生することができ、爪部（３００）の厚さが金属プレートから自由端に向かってどんどん薄くなることにより、簡単に電流を発生できる。 In addition, the conventional claw seat (30) has a circular metal plate housed inside a ring-shaped permanent magnet provided in the hub body, and the periphery of the metal plate has the number of poles of the ring-shaped permanent magnet and the number of poles. Claws (300) which are equal and which magnetically act on the ring-shaped permanent magnet and each other are protruded. The claw portion (300) can easily generate a change in the magnetic field, and the claw portion (300) can easily generate an electric current as the thickness of the claw portion (300) decreases from the metal plate toward the free end.
しかしながら、前記従来の爪座（３０）とリング状永久磁石とが磁気的に作用する場合、爪部（３００）の幅が均一であると、爪部（３００）とリング状永久磁石との磁気的な作用が強すぎるため、爪座（３０）はリング状永久磁石に対して回転し難く、従って、自転車に乗る際、ペダルを漕ぐ力は強くなければならない。 However, when the conventional claw seat (30) and the ring-shaped permanent magnet magnetically act, if the width of the claw (300) is uniform, the magnetic force between the claw (300) and the ring-shaped permanent magnet is increased. Is too strong to rotate the pawl seat (30) with respect to the ring-shaped permanent magnet, and therefore, the pedaling force must be strong when riding a bicycle.
そこで、案出されたのが本考案であって、楽に駆動され、且つ優れる発電効果を有する自転車用発電ハブを提供することを目的としている。 Therefore, the present invention has been devised, and an object of the present invention is to provide a bicycle power generation hub that is easily driven and has an excellent power generation effect.
本願の請求項１の考案は、ハブ本体と、該ハブ本体の内部に設けられるリング状永久磁石と、該リング状永久磁石の内周側に設けられる一対の爪座と、該一対の爪座に挟持されると共に、外周側にコイルが設けられる固定子と、該固定子の中央部に収容されるポール部材とを備える自転車用発電ハブであって、
前記ポール部材がシリンダー状であり、
前記爪座が、円形の金属プレートと、該金属プレートの周縁から該金属プレートに垂直方向に突設される複数の爪部とを備え、
前記爪部の厚さは金属プレートから自由端に向かってどんどん薄くなると共に、該爪部の幅は金属プレートから自由端に向かってどんどん狭くなることを特徴とする自転車用発電ハブである。
The invention of claim 1 of the present application is directed to a hub body, a ring-shaped permanent magnet provided inside the hub body, a pair of claw seats provided on the inner peripheral side of the ring-shaped permanent magnet, and the pair of claw seats. A bicycle power generation hub including a stator, which is provided with a coil on the outer peripheral side thereof, and a pole member accommodated in a central portion of the stator,
The pole member is cylindrical,
The claw seat includes a circular metal plate, and a plurality of claw portions projecting from the peripheral edge of the metal plate in a direction perpendicular to the metal plate,
The power generation hub for a bicycle according to claim 1, wherein the thickness of the claw portion is gradually reduced from the metal plate toward the free end, and the width of the claw portion is gradually reduced from the metal plate toward the free end.
本願の請求項２の考案は、かかる自転車用発電ハブにおいて、前記ポール部材が、矩形金属板を捲きまわすことによってシリンダー状の構造となるものである。 According to a second aspect of the present invention, in the bicycle power generation hub, the pole member has a cylindrical structure by winding a rectangular metal plate.
本考案は上記の課題を解決するものであり、爪座における爪部の厚さは金属プレートから自由端に向かってどんどん薄くなると共に、爪部の幅は金属プレートから自由端に向かってどんどん狭くなっているので、爪座とリング状永久磁石との磁気的な作用を降下することができ、ペダルを漕ぐ力は軽く、楽に発電ハブを駆動することができる。 The present invention solves the above-described problem, and the thickness of the claw portion in the claw seat is gradually reduced from the metal plate toward the free end, and the width of the claw portion is gradually reduced from the metal plate toward the free end. As a result, the magnetic action between the pawl seat and the ring-shaped permanent magnet can be lowered, the pedaling force is light, and the power generation hub can be easily driven.
以下、添付図面を参照して本考案の好適な実施の形態を詳細に説明する。尚、下記実施例は、本考案の好適な実施の形態を示したものにすぎず、本考案の技術的範囲は、下記実施例そのものに何ら限定されるものではない。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the following embodiments are merely preferred embodiments of the present invention, and the technical scope of the present invention is not limited to the following embodiments.
図１は本考案に係る自転車用発電ハブにおける爪座、ポール部材及び固定子を示す分解斜視図であり、図２は本考案に係る自転車用発電ハブの断面図である。 FIG. 1 is an exploded perspective view showing a claw seat, a pole member, and a stator in a bicycle power generation hub according to the present invention, and FIG. 2 is a cross-sectional view of the bicycle power generation hub according to the present invention.
図１及び図２に示すように、本考案に係る自転車用発電ハブは、ハブ本体（１０）と、ハブ本体（１０）の内周側に設けられるリング状永久磁石（１１）と、リング状永久磁石（１１）の内周側に設けられる一対の爪座（１２）と、一対の爪座（１２）によって挟持されると共に、外周側にコイル（不図示）が配置される固定子（１３）と、固定子（１３）の中央部に収容されるポール部材（１４）とを備える。なお、ハブ本体（１０）はカバーとしての機能も果たすが、ハブ本体（１０）の外側に、別体のカバーが設けられてもよい。 As shown in FIGS. 1 and 2, the bicycle power generation hub according to the present invention includes a hub body (10), a ring-shaped permanent magnet (11) provided on the inner peripheral side of the hub body (10), and a ring-shaped permanent magnet. A pair of pawl seats (12) provided on the inner peripheral side of the permanent magnet (11), and a stator (13) sandwiched between the pair of pawl seats (12) and having a coil (not shown) disposed on the outer peripheral side. ) And a pole member (14) housed in the center of the stator (13). Although the hub body (10) also functions as a cover, a separate cover may be provided outside the hub body (10).
前記固定子（１３）の中央部に収容されるポール部材（１４）は、矩形金属板を捲きまわすことによってシリンダー状の構造となる。又、前記爪座（１２）は、円形の金属プレートと、その周縁に突設される複数の爪部（１２０）とを備え、該爪部（１２０）の厚さは金属プレートから自由端に向かってどんどん薄くなると共に、該爪部（１２０）の幅は金属プレートから自由端に向かってどんどん狭くなる。 The pole member (14) housed in the center of the stator (13) has a cylindrical structure by winding a rectangular metal plate. The claw seat (12) includes a circular metal plate and a plurality of claw portions (120) protruding from a peripheral edge thereof, and the thickness of the claw portion (120) is increased from the metal plate to a free end. As the thickness decreases, the width of the claw (120) decreases from the metal plate toward the free end.
本考案に係る自転車用発電ハブのポール部材（１４）は、金属プレートを捲きまわすことによってシリンダー状の構造とされており、固定子（１３）の中央部にポール部材（１４）を収容した際、ポール部材（１４）が車軸をリング状に囲むことができる。即ち、本考案は金属プレートを捲きまわすことにより、従来のポール部材では車軸を本当のリング状に囲めなかったという問題を解決する。 The pole member (14) of the bicycle power generation hub according to the present invention has a cylindrical structure by winding up a metal plate. When the pole member (14) is accommodated in the center of the stator (13). The pole member (14) can surround the axle in a ring shape. That is, the present invention solves the problem that the axle cannot be surrounded in a true ring shape by the conventional pole member by winding the metal plate.
又、本考案の爪座（１２）における爪部（１２０）の厚さは金属プレートから自由端に向かってどんどん薄くなると共に、爪部（１２０）の幅は金属プレートから自由端に向かってどんどん狭くなっているので、爪座（１２）とリング状永久磁石（１１）との磁気的な作用を降下することができ、従って、ペダルを漕ぐ力は軽く、楽に発電ハブを駆動することができる。 Further, the thickness of the claw portion (120) of the claw seat (12) of the present invention becomes thinner from the metal plate toward the free end, and the width of the claw portion (120) increases from the metal plate toward the free end. Since it is narrow, the magnetic action of the claw seat (12) and the ring-shaped permanent magnet (11) can be lowered, and therefore, the pedaling force is light and the power generation hub can be easily driven. .
本考案に係る自転車用発電ハブにおけるポール部材（１４）と爪座（１２）以外の部材は従来と等しいので、詳細な説明を省略する。又、固定子（１３）の中央部にシリンダー状のポール部材（１４）を収容するため円形の取付孔が形成されているが、これはこの考案の属する技術の分野における通常の知識を有する者が容易に考案することができる部分ので、詳細な説明も省略する。 The members other than the pawl member (14) and the pawl seat (12) in the bicycle power generation hub according to the present invention are the same as those in the related art, and a detailed description thereof will be omitted. Also, a circular mounting hole is formed in the center of the stator (13) to accommodate the cylindrical pole member (14), which has a general knowledge in the technical field to which the present invention belongs. Since it can be easily devised, detailed description is also omitted.
本考案は上記の構成を有するものであって、爪座における爪部の厚さは金属プレートから自由端に向かってどんどん薄くなると共に、爪部の幅は金属プレートから自由端に向かってどんどん狭くなっているため、爪座とリング状永久磁石との磁気的な作用を降下することができ、従って、ペダルを漕ぐ力は軽く、楽に発電ハブを駆動することができる。 The present invention has the above-described structure, and the thickness of the claw portion in the claw seat is gradually reduced from the metal plate toward the free end, and the width of the claw portion is gradually reduced from the metal plate toward the free end. As a result, the magnetic action between the claw seat and the ring-shaped permanent magnet can be lowered, and therefore, the pedaling force is light and the power generation hub can be easily driven.
