Description

【0001】
【発明の属する技術分野】
本発明は、車輪用電飾装置に関し、さらに詳しくは、車両走行中に加え車両停止直後にも発光させることができる車輪用電飾装置に関する。
【0002】
【従来の技術】
乗用車やバス・トラック等の走行車両は、夜間には車両側面が暗いので、他の車両から車輪の位置を確認することができるように安全性を向上させるためと、装飾性を高めるために、車輪に発光体を配設し、夜間の車両走行時に車輪を発光させるようにした電飾装置が提案されている。
【0003】
たとえば、特許文献1には、車両本体にマグネットを設け、車輪内側面に発電コイルを設けて車輪の回転に伴って発電し、その電流を利用して車輪外側面の発光体を発光させる電飾装置が提案されている。しかし、このような構成の電飾装置では、車両走行中には発光するものの、車両停止後には車輪の回転停止とともに発電がなされなくなってしまうので、発光体が発光せず、車両停止時の安全性と装飾性が得られなくなるという問題があった。
【0004】
【特許文献1】
登録実用新案第30742239号公報
【0005】
【発明が解決しようとする課題】
従って、本発明の課題は、車両走行中に加え車両停止直後にも発光させることができる車輪用電飾装置を提供することにある。
【0006】
【課題を解決するための手段】
本発明によれば、相対する2つの回転体が車輪外側に車輪軸を回転中心として装着され、前記回転体の一方にはマグネットが配設され、前記回転体の他方には発電コイルと発光体が配設されるとともに、前記回転体のいずれか一方が回転自在に車輪に装着され、車輪の回転によって前記発電コイルが発電し前記発光体を発光させる車輪用電飾装置が提供される。
【0007】
また、本発明によれば、前記回転体の少なくとも一方に反射部材を設けた前記車輪用電飾装置が提供される。
【0008】
また、本発明によれば、回転自在に車輪に装着された前記回転体に、風を受けて回転体を回転させる受風部材を設けた前記車輪用電飾装置が提供される。
【0009】
【発明の実施の形態】
以下、本発明の構成について図面を参照しながら詳細に説明する。図1は、本発明の車輪用電飾装置の一例を示す部分断面図であり、図2は内側の回転体3を車両外側から見た正面図、図3は外側の回転体4を車両外側から見た正面図である。図において、車輪軸2が回転中心となるように一致させながら、相対する2つの回転体3,4が装着されている。2つの回転体のうち、内側に位置する回転体3には、マグネット5が配設されている。外側に位置する回転体4には、発電コイルと発光体6が一体化した部材が配設されており、マグネット5と相対する位置に配置されている。
【0010】
そして、回転体4は、回転自在継手7を介して回転自在に車輪1に装着されている。したがって、車両走行を開始すると回転体4は空回りし、次いで徐々に回転し始めるようになる。このように、回転体3と回転体4とは回転速度の差が生じるために、回転体3に配設されたマグネット5に相対する位置を、回転体4に配設された発電コイルと発光体6とが通過する際に、発電コイルに電流が生じ発光体が点滅する。また、車両が減速し停止した際にも、その停止後には、回転体3は回転を停止するが、回転自在に取り付けられた回転体4は慣性によって回転を続けるために、やはり発電コイルに電流を生じ、発光体を点滅させつづける。ゆえに、車両走行時のみならず、車両停止直後にも発光体が点滅するので、夜間の停車時にも安全性と装飾性を得ることができる。また、回転体の回転差を利用して発電するので、電池等の電源が不要であるうえに、マグネット、発電コイルや発光体が全て車軸1の外側に配されるので、従来の技術に比べ装着が容易であり、複雑な配線も不要となる。
【0011】
回転体3,4は、そのいずれか一方が回転自在に車輪に装着されればよく、図1とは逆に回転体3が回転自在に装着されていてもよい。図1においては、回転体3,4の装着位置をホイールキャップ11としたが、ホイール10や車輪軸2の先端であってもよい。また、回転体の材質や形状は特に限定されず、例えば、金属や樹脂等を用いて、円盤状、スポークを用いた構造であってもよく、透明な素材であってもよい。また、車輪1に装着された図1のホイール10やホイールキャップ11、図示しないディスクブレーキドラムをそのまま回転体の一つとして用いてもよい。また、マグネット5を有する回転体を外側に装着し、発電コイルと発光体6を有する回転体を内側に装着しても、発光体の光が外部から視認できるものであればよい。
【0012】
発光体も特に限定されず、LEDや電球等を用いればよく、1個または複数個用いられる。マグネット5や発電コイルについても、1個であっても複数個であってもよい。
【0013】
回転自在継手7としては、各種のものが使用でき、例えば、ベアリング、軸と軸受とを鉱物油等の潤滑油を介して連結した回転継手、粘性流体を介して回転を伝える流体継手等を用いることができる。
【0014】
また、図1〜3においては、回転体3,4に、反射部材8が設けられている。反射部材8は、発光体が発した光を受けて反射・散乱させ、電飾効果をさらに向上させることができる。
【0015】
また、図4は回転体の他の例であるが、回転自在に装着された回転体に、羽根等の風を受けて回転体を回転させる受風部材9を設けることで、車両走行時に風を受けて回転体がより回転しやすくなるので好ましい。あるいは、反射部材8を受風部材9となるような形状に形成してもよい。
【0016】
【発明の効果】
本発明に従って、相対する2つの回転体を車輪外側に車輪軸を回転中心として装着し、前記回転体の一方にはマグネットを配設し、前記回転体の他方には発電コイルと発光体を配設して、前記回転体のいずれか一方を回転自在に車輪に装着することによって、車両走行中に加え車両停止直後にも発光させることができる車輪用電飾装置を得ることができる。

Registered Utility Model No. 30742239
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a wheel illumination device that can emit light immediately after the vehicle stops as well as during vehicle travel.
[0006]
[Means for Solving the Problems]
According to the present invention, two opposing rotating bodies are mounted on the outside of a wheel with a wheel shaft as a center of rotation, a magnet is disposed on one of the rotating bodies, and a power generating coil and a light emitting body are disposed on the other of the rotating bodies. Is provided, and one of the rotating bodies is rotatably mounted on a wheel, and the wheel generating device generates electric power by the rotation of the wheel, and the light emitting device emits the light.

[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional view showing an example of a wheel illumination device of the present invention. FIG. 2 is a front view of an inner rotating body 3 as viewed from the outside of the vehicle. FIG. It is the front view seen from. In the figure, two opposing rotating bodies 3 and 4 are mounted while matching so that the wheel shaft 2 becomes the center of rotation. Of the two rotating bodies, a magnet 5 is disposed on the rotating body 3 located inside. A member in which the power generation coil and the light emitting body 6 are integrated is disposed on the rotating body 4 located on the outside, and is disposed at a position facing the magnet 5.
[0010]
The rotating body 4 is rotatably mounted on the wheel 1 via a rotating joint 7. Therefore, when the vehicle starts running, the rotating body 4 idles, and then gradually starts to rotate. As described above, since a difference in rotation speed occurs between the rotating body 3 and the rotating body 4, the position facing the magnet 5 provided on the rotating body 3 is set to a position corresponding to the power generation coil provided on the rotating body 4. When passing through the body 6, a current is generated in the power generation coil, and the light emitting body blinks. Also, when the vehicle decelerates and stops, after the stop, the rotating body 3 stops rotating. However, since the rotating body 4 that is rotatably mounted continues to rotate by inertia, current is also applied to the power generating coil. And the illuminant continues to blink. Therefore, since the light-emitting body flashes not only when the vehicle is running but also immediately after the vehicle stops, safety and decorativeness can be obtained even when the vehicle is stopped at night. In addition, since power is generated using the rotation difference of the rotating body, a power source such as a battery is not required. In addition, since the magnet, the power generating coil, and the light-emitting body are all disposed outside the axle 1, compared with the conventional technology, Mounting is easy and complicated wiring is not required.
[0011]
One of the rotating bodies 3 and 4 may be rotatably mounted on the wheel, and the rotating body 3 may be rotatably mounted opposite to FIG. In FIG. 1, the mounting positions of the rotating bodies 3 and 4 are the wheel caps 11, but may be the wheel 10 or the tip of the wheel shaft 2. The material and shape of the rotating body are not particularly limited. For example, the rotating body may be made of a metal, a resin, or the like, and may have a disk shape, a structure using spokes, or a transparent material. Further, the wheel 10 and the wheel cap 11 shown in FIG. 1 mounted on the wheel 1 and the disc brake drum (not shown) may be used as one of the rotating bodies. Further, even if the rotating body having the magnet 5 is mounted on the outside and the rotating body having the power generation coil and the light emitting body 6 is mounted on the inside, it is sufficient if the light of the light emitting body can be visually recognized from the outside.
[0012]
The luminous body is not particularly limited either, and an LED or a light bulb may be used, and one or a plurality of luminous bodies may be used. The number of magnets 5 and power generation coils may be one or more.
[0013]
As the rotatable universal joint 7, various types can be used. For example, a bearing, a rotary joint in which a shaft and a bearing are connected via lubricating oil such as mineral oil, a fluid coupling for transmitting rotation via a viscous fluid, and the like are used. be able to.
[0014]
Also, in FIGS. 1 to 3, the reflecting members 8 are provided on the rotating bodies 3 and 4. The reflecting member 8 receives and reflects and scatters the light emitted from the light emitting body, so that the electric decoration effect can be further improved.
[0015]
FIG. 4 shows another example of a rotating body. By providing a wind receiving member 9 for rotating a rotating body by receiving wind from a blade or the like on a rotatably mounted rotating body, the wind is reduced when the vehicle travels. This is preferable because the rotating body is more easily rotated in response to this. Alternatively, the reflecting member 8 may be formed in a shape that becomes the wind receiving member 9.
[0016]
【The invention's effect】
According to the present invention, two opposing rotating bodies are mounted on the outer side of a wheel with a wheel shaft as a center of rotation, a magnet is arranged on one of the rotating bodies, and a generator coil and a light emitting body are arranged on the other of the rotating bodies. By mounting any one of the rotating bodies to the wheels so as to be freely rotatable, it is possible to obtain an electric decoration device for a wheel which can emit light immediately after the vehicle is stopped as well as during traveling of the vehicle.
