A structure is disclosed.

In addition, according to US Pat. No. 4.75.919, “lighted wheel cover with a self-contained imertia-operated generator,” when mounted on the wheel and the wheel rotates, A technique has been disclosed in which electricity is generated in a coil by parody electron induction of the coil so that light is generated in a light emitting diode connected to the coil.

These known techniques generally represent suitable techniques but are not applicable in the present invention.

That is, the above known technologies have a structure in which a magnet, which is fixed to the shaft through the shaft and the bearing, emits light while the wheel rotates, with a relative movement with respect to the coil. Known techniques are for manufacturing wheels by embedding light emitting members, coil members, and magnet members inside the wheel body, which makes the manufacturing process difficult or cumbersome, and requires many components, thereby increasing costs. There are disadvantages.

In addition, there is a drawback that cannot be widely used or used in technical fields other than roller skating, for example, wheels of automobiles or motorcycles, etc., due to the limitation of the use that is mounted and used in inline roller skating.

The present invention, as a result of intensive examination by paying attention to the drawbacks of the prior art as described above, the wheel of the inline roller skates by a fixed shaft that is not affected by the rotational wheel, that is, the rotational force of the rotating body apart from the wheel shaft of the roller skates Not only can be applied to, but also can be useful for all rotating bodies such as automobile wheels and motorcycle wheels, and the simple components can lead to an efficient manufacturing process and reduce weight. It is an object of the present invention to provide a small generator using a central weight and a light emitting device having the same.

In order to achieve the above object, a small generator using the center of gravity of the present inventors and a light emitting unit having the same,

A housing body each having two inserting portions therein; Two bearings inserted and fixed to two inserting portions formed inside the housing main body; An axle built into the two bearings; A center of gravity weight in which an eccentric fitting hole eccentrically arranged on an outer axle surface between the two bearings is perforated at one end thereof; A ring-shaped permanent magnet fitted to the tip of the axle; A coil assembly fitted to the front end side of the housing main body to surround the outer circumference of the permanent magnet; At least two light emitting diodes (LEDs) connected to a coil wound around the coil assembly and emitting light; And a reflector fastened to the front end side of the housing body.

A screw portion may be further formed on the outer periphery of the front end side of the housing body, and a screw coupling portion may be further formed on the inner periphery of the reflector so that the screw portion and the screw coupling portion may be screwed onto the housing body and the reflector.

In addition, an outer flange having a plurality of fastening holes for fastening the housing body to the wheel fixing bolt of the automobile wheel or the motorcycle wheel may be further formed at the outer circumferential edge of the rear end of the housing body.

The compact generator using the center of gravity of the present invention and the light emitting body having the same, as described above, the housing body is coupled to a wheel such as an automobile wheel or a motorcycle wheel to produce a beautiful light emission color by the rotation of the wheel. Not only can the appearance of a car or motorcycle be equipped with a more beautiful look, but also simple components can increase the efficiency of the work process, it is possible to reduce the cost.

Hereinafter, the configuration and operation of the compact generator using the center of gravity of the present invention and the light emitting body having the same will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view showing the components of a small generator using the center of gravity weight of the present invention and a light emitting device having the same, Figure 2 is a configuration showing a combined state of the small generator using the center of gravity weight of the present invention and a light emitting body having the same It is a cross section.

As shown, the inserting portion 11 is formed on the inner central portion and the rear end wall, respectively, the housing main body 10 having the front end open, and the inserting portion 11 formed on the rear end wall and the central portion of the housing main body 10. ), Two bearings 20 and 20 inserted into and fixed to the axle, an axle 30 arranged in a central portion of the two bearings 20 and 20, and an eccentric fitting hole 41 fitted to the axle 30. The inner center of the coupling hole 51 is fixed to the front end side of the center of gravity weight 40 is eccentrically through the one end and the axle 30 built in the two bearings (20, 20) A permanent magnet 50, a coil assembly 60 inserted into the front end side of the housing main body to surround the outer part of the permanent magnet 50, and the coil 61 wound thereon, and the coil assembly 60 The light emitting diode 70 is electrically connected to the coil 61 wound around and the open tip side of the housing main body 10 is blocked. A reflector 80 that reflects light emanating from the distal end side is fastened to the outer surface and the thread of the housing body 10.

In order to screw the housing body 10 and the reflector 80, a screw part 12 and a screw fastening part 81 may be formed on an outer circumferential surface of the front end side of the housing body 10 and an inner side of one side end of the reflector, respectively. have.

The center of gravity weight 40, as the eccentric fitting hole 41 is fitted into the circumferential edge of the axle 30 in one side of the center of gravity weight 40, the bottom side is always lower Point in direction.

The small generator using the center of gravity of the present inventors configured as described above, and the light emitting body 100 provided with the same, the wheel fixing bolt (B) such as automobile (C) wheel or motorcycle wheel as shown in Figure 4 and 5 The rear end side of the housing body may be mounted to obtain a beautiful rotating color rotating body through light emitted from the light emitting diodes when the wheel is rotated.

The reason why the light emitting diode 70 emits light as the wheel is rotated as described above is that the housing main body 10 having the rear end side mounted to the wheel fixing bolt for fixing the wheel to the wheel is rotated as the wheel is rotated. The coil assembly 60 is rotated in the same direction as that of the wheel, and thus the coil assembly 60 fitted to the front end side of the housing body 10 is rotated in the same manner as the housing body 10. An electrical force generated by a parody electron induction action formed between the 60 and the permanent magnet 50 located inside the coil assembly 60 is transferred through the coil 61 wound on the coil assembly 60. The electrical power is supplied to the light emitting diode 70 electrically connected to the coil 61.

As shown in FIG. 3, the axle 30 inserted into the housing body 10 while the housing body 10 is rotated in the same direction as the rotation direction of the wheel by the wheel H is shown in FIG. 3. A weight center weight 40 eccentrically coupled to an outer circumferential surface of the axle 30 and two bearings 20 and 20 located at both ends of the weight center weight 40 and the axle 30 is built up. By being able to be fixed without being rotated, the permanent magnet 50, which is a fixed body fitted to the front end side of the axle 30, is rotated by the rotation of the housing main body 10 and is external to the permanent magnet 50. Parody electron induction action is generated between the coil assembly 60, which is a rotating body wrapped around, which is sufficient to have a difference from the above-described known technology.

In other words, in the prior art, a fixed body and a rotating body made of a coil and a permanent magnet having a parody electron induction action are configured inside the wheel as a rolling means, and thus are limited to only limited wheels such as inline skates or roller skates. Unlike the present invention, the axle 30, which is a structure in which electricity is generated by interaction, and the coil assembly 60, which is a rotating body, are not affected by the wheel, which is the axis of the wheel, on which the rotating body is rotated. As all components are interpolated therein, it is possible to separate and use the wheel separately, such as a car or a motorcycle, so that there is no restriction on use.
