Description
本考案は、特にリング状に車軸を囲む自転車の発電用ハブのポール部材に関するものである。 The present invention relates to a pole member of a power generation hub for a bicycle that surrounds an axle in a ring shape.
夜間に自転車に乗る場合には、危険を防止するために充分な照明が必要である。又、充分な照明を得るため、自転車は小型発電機又はバッテリーのような電力供給システムを装備しているが、該電力供給システムは使用電力が限定された消耗品であるので、現在では小型発電機がよく使用されている。 When riding a bicycle at night, sufficient lighting is necessary to prevent danger. Moreover, in order to obtain sufficient lighting, the bicycle is equipped with a power supply system such as a small generator or a battery. However, since the power supply system is a consumable item with limited power consumption, it is currently a small power generator. The machine is often used.
従来の小型発電機は設置スペースを小さくするために、自転車の発電用ハブと一体に形成する構造を有し、発電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。又、前記従来のハブ式発電機は既に公知のものであるので、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 reduce the installation space, a conventional small generator has a structure that is formed integrally with a power generation hub of a bicycle, and generates power by generating a magnetic field change due to the relative rotation of a magnet and a coil inside the power generation hub. To do. Further, since the conventional hub type generator is already known, the description of the detailed members inside is omitted, and only the members for generating the change of the magnetic field will be described.
即ち、図４に示すように、磁場の変化を発生するために、発電用ハブの内部における部材は互いに組合せる一対の爪座３０を有し、両爪座３０同士の間に外側にコイルを巻装した固定子３１が設けられ、該固定子３１の中央にポール部材（回転子）３２を挿入するため取付孔３１０が形成される。
前記ポール部材３２は、円形のリング形状として車軸４０を囲む構造が望ましいが、ポール部材３２を円形のリング形状に製造するには製造が複雑となり、難しく、高価となるため、従来においては、前記ポール部材３２を配設するにあたり、複数枚のポールプレートをリング状になるようにして前記固定子３１の中央における取付孔３１０に配置している。
That is, as shown in FIG. 4, in order to generate a change in the magnetic field, the members inside the power generation hub have a pair of claw seats 30 to be combined with each other, and a coil is placed between the claw seats 30 on the outside. A wound stator 31 is provided, and a mounting hole 310 is formed in the center of the stator 31 for inserting a pole member (rotor) 32.
The pole member 32 preferably has a circular ring shape and surrounds the axle 40. However, the manufacture of the pole member 32 in a circular ring shape is complicated, difficult, and expensive. In disposing the pole member 32, a plurality of pole plates are arranged in a ring shape in the mounting hole 310 in the center of the stator 31.
しかしながら、前記ポール部材３２の構成は、複数枚のポールプレートをリング状になるようにして車軸４０を囲む構造としているが、ポールプレートが一体に形成されたものでないので、作業性が悪くかつ優れた発電効果を達成することができない。
そこで、案出されたのが本考案であって、円形のリング状に車軸を囲むようにした自転車の発電用ハブのポール部材を提供することを目的としている。
However, the pole member 32 has a structure in which a plurality of pole plates are formed in a ring shape to surround the axle 40. However, since the pole plates are not integrally formed, workability is poor and excellent. The power generation effect cannot be achieved.
Accordingly, the present invention has been devised and an object of the present invention is to provide a pole member for a bicycle power generation hub that surrounds an axle in a circular ring shape.
本願の請求項１の考案は、自転車の発電用ハブのポール部材であって、前記ポール部材を板状金属プレートを巻装して中心に車軸が嵌合する中空部を有する円筒形のシリンダー構造になるようにしたことを特徴とする。 The invention of claim 1 of the present application is a pole member of a power generation hub for a bicycle, and is a cylindrical cylinder structure having a hollow portion around which the axle is fitted by winding a plate-like metal plate around the pole member. It was made to become.
本願の請求項２の考案は、請求項１に記載の自転車の発電用ハブのポール部材において、前記板状金属プレートは溶接手段によって中空部を有する円筒形のシリンダー構造に形成したことを特徴とする。
本願の請求項３の考案は、請求項１に記載の自転車の発電用ハブのポール部材において、前記中空部を有する円筒形のシリンダー構造の外側に固定パイプが配設されることを特徴とする。
The invention of claim 2 of the present application is characterized in that in the pole member of the bicycle power generation hub according to claim 1, the plate-like metal plate is formed into a cylindrical cylinder structure having a hollow portion by welding means. To do.
The invention of claim 3 of the present application is characterized in that, in the pole member of the power generation hub of the bicycle according to claim 1, a fixed pipe is disposed outside the cylindrical cylinder structure having the hollow portion. .
本考案は上記の課題を解決するものであり、板状金属プレートを巻装して中空部を有する円筒形のシリンダー構造にしたことにより、製造が簡単で且つ優れた発電効果を有するポール部材を提供できる。 The present invention solves the above-mentioned problems, and by making a cylindrical cylinder structure having a hollow portion by winding a plate-shaped metal plate, a pole member that is easy to manufacture and has an excellent power generation effect is provided. Can be provided.

In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.
図１は本考案に係る自転車の発電用ハブのポール部材にかかる実施例を示す斜視図であり、図２は本考案に係る自転車の発電用ハブのポール部材と自転車の発電用ハブにおける他の部材の分解斜視図であり、図３は本考案に係る自転車の発電用ハブのポール部材と固定パイプの分解斜視図である。 FIG. 1 is a perspective view showing an embodiment of a pole member of a bicycle power generation hub according to the present invention, and FIG. FIG. 3 is an exploded perspective view of a member, and FIG. 3 is an exploded perspective view of a pole member and a fixed pipe of a power generation hub of a bicycle according to the present invention.
図１に示すように、本考案に係る自転車の発電用ハブに使用されるポール部材１０は、板状金属プレート１１を巻装して丸めて中央に車軸４０が嵌合する中空部１０ａを有する円筒形のシリンダー構造としたものであって、該円筒形のシリンダー構造の内側には前記板状金属プレート１１の端部を折り曲げて形成した位置決めプレート１２が設けられている。
本実施例について、前記板状金属プレート１１は巻装した状態の始端部及び終端部をそれぞれ溶接手段によって中空部１０ａを有する円筒形のシリンダー構造に形成するが、超音波溶接又は他の結合手段によって中空部を有する円筒形のシリンダー構造に形成してもよい。
As shown in FIG. 1, a pole member 10 used for a power generation hub of a bicycle according to the present invention has a hollow portion 10a around which a axle 40 is fitted by winding a plate-like metal plate 11 and rolling it. A cylindrical cylinder structure is provided, and a positioning plate 12 formed by bending the end of the plate-like metal plate 11 is provided inside the cylindrical cylinder structure.
In the present embodiment, the plate-like metal plate 11 is formed in a cylindrical cylinder structure having a hollow portion 10a at the start end and the end end in a wound state by welding means, but ultrasonic welding or other coupling means Alternatively, a cylindrical cylinder structure having a hollow portion may be formed.
図２に示すように、本考案に係る自転車の発電用ハブのポール部材１０の組合方式は従来と同様であるが、該ポール部材１０を固定子３１の取付孔３１０に挿入する際、前記ポール部材１０の位置決めプレート１２がワイヤを設置するための車軸４０の軸方向に形成した溝４１に嵌入されていることにより、ポール部材１０と車軸４０の固定効果を高めることができる。 As shown in FIG. 2, the method of combining the pole members 10 of the power generation hub of the bicycle according to the present invention is the same as the conventional one. However, when the pole members 10 are inserted into the mounting holes 310 of the stator 31, the poles Since the positioning plate 12 of the member 10 is fitted in the groove 41 formed in the axial direction of the axle 40 for installing the wire, the fixing effect of the pole member 10 and the axle 40 can be enhanced.
また、前記ポール部材１０の形成の変形例として、図３に示すように、前記板状金属プレート１１を巻装して、中空部を有する円筒形のシリンダー構造のポール部材１０とした後で、前記溶接手段を施した後であれば強固となるが、該ポール部材１０の外側に中空の固定パイプ１３を嵌合させることで、前記板状金属プレート１１を巻装した状態の始端部及び終端部をそれぞれ溶接手段を施すことなく円筒形のシリンダー構造を有するポール部材１０を提供することも勿論可能である。 As a modification of the formation of the pole member 10, as shown in FIG. 3, after the plate-shaped metal plate 11 is wound to form a pole member 10 having a cylindrical cylinder structure having a hollow portion, It becomes strong after the welding means is applied, but by fitting a hollow fixed pipe 13 to the outside of the pole member 10, the starting end and the terminal end of the state in which the plate-shaped metal plate 11 is wound. It is of course possible to provide the pole member 10 having a cylindrical cylinder structure without applying welding means to the respective parts.
本考案は上記の構成を有するので、板状金属プレートを巻装して中空部を有する円筒形のシリンダー構造としたことにより、優れた発電効果を有するポール部材を提供できる。 Since the present invention has the above-described configuration, a pole member having an excellent power generation effect can be provided by forming a cylindrical cylinder structure having a hollow portion by winding a plate-shaped metal plate.
