Description

Wheel light

The present invention relates to a wheel light, in more detail to be mounted on a rotating wheel, such as a bicycle wheel light to emit light to produce power according to the rotation of the wheel without a separate power supply to emit light The developed wheel light.

A wheel light refers to a light emitted by being mounted on a wheel, that is, a wheel, to be mounted on a wheel of a bicycle, a motorcycle, a car, and various riding equipments so that light is emitted.

Such wheel lights give aesthetics while drawing a circle even when light is emitted from a dot according to the rotation of the wheel. Recently, small and low-power LEDs are applied to provide a variety of colors and shapes to enhance the user's personality.

Recently, as interest in health increases, more and more people use bicycles at night as well as during the day. The headlights and taillights are attached to the bicycles for safe driving at night so that people around them can easily recognize them. If wheel lights are added to the car, it will be more secure at night.

Due to the characteristics of the rotating wheels, there are various prior arts that can emit light by self-generation without supplying a separate power source, but all the shafts and hubs of the wheels must be replaced. In particular, the hub is connected to the tires and tires. Increasing production costs and the durability may be weakened.

Mounted and fixed between the spokes 13 on both sides of the outer surface of the hub 12, a coil 221 wound along an inner space is mounted, and extends in parallel with the shaft 11 between the coils 221. A body 22 mounted with a driven shaft 223 which rotates and is fixed so that two driven magnets 222 are differently polarized in an outward direction along an outer circumferential surface thereof;

One end protrudes from the body 22 and extends, and then reverses while drawing an arc, and then extends back to the body 22. Each of the anodes of the current generated in the coil 221 according to the rotation of the driven shaft 223 is A pair of electrode rods 23 connected to each other;

Two connecting terminals 241 are respectively extended on the front and rear surfaces and inserted between the inner diameters of the four fasteners 242 having a cylindrical shape through which the electrode rods 23 and the outer diameter of the electrode rods 23 are inserted into the electrode rods 23. Wheel light, characterized in that it is composed of one or more LED lamps 24 which are fixedly coupled with the < RTI ID = 0.0 >

The present invention relates to a wheel light (2) to enable the LED lamp 24 to emit light by self-power generation. In the existing various prior arts, a basic structure for power generation has a principle of forming a magnet rotating in the center of a coil. There are quite a few.

However, this structure is formed using a shaft (11) that is fixed to the fork to mount the wheel (1) of the bicycle and the hub (12) rotates through the shaft (11) in the center of the wheel (1), but in this case The structure of the shaft 11 and the hub 12 is complicated, and in the process of separately manufacturing, there is a problem that the increase in the manufacturing cost and the durability is weakened.

In this regard, the present application first mounts the driving magnets 21 on the shaft 11 along the outer circumferential surface thereof, but the polarities of the driving magnets 21 are arranged differently from each other, and the shaft 11 made of carbon steel is usually made of a ferromagnetic metal. When arranging the driving magnet 21, there is a possibility that the arrangement may be disturbed due to the polarity, and it is advantageous and simple to arrange the driving magnet 21 after wrapping the shaft 11 with a synthetic resin material in the middle rather than directly contacting it. After winding the tape, it is also possible to use a method of arranging the driving magnets 21 and winding them back with tape.

In addition, in the case of the hub 12, the shaft 11 is mounted on both sides by a bearing, and the space therebetween has a space in which a part on which the driving magnet 21 is mounted is inserted into a space having no meaning. However, it is necessary to use a non-magnetic metal such as stainless so that the change of the magnetic field due to the change of the position of the driving magnet 21 according to the rotation of the hub 12 can be external.

In this structure, when the bicycle is driven, the shaft 11 is fixed and the wheel 11 including the hub 12 rotates, while the shaft 11 relatively spaced relative to the body 22 rotates. The magnetic force by the driving magnet 21 is changed.

Accordingly, the driven shaft 223 equipped with the driven magnet 222 rotates in response to the attraction force and the repulsive force of the driving magnet 21, and this rotation allows the coil 221 to produce power.

In addition, the two ends of the wire wound on the coil 221 is connected to each other electrode 23, the alternating current is produced due to the nature of the current produced electrode 23 is generated by alternating the positive electrode and the negative electrode and close contact with the electrode 23 The connection terminal 241 to cause the LED lamp 24 to emit light.

At this time, the fixture 242 has a structure that can easily change the position of the LED lamp 24.

In the present invention, when four driving magnets 21 are formed, the change of pole occurs four times while making one rotation, and accordingly, the driven shaft 223 having the driven magnet 222 makes two rotations and thus the rotation speed. Is faster, so you can produce more power.

In addition, the body 22 of the present application can also be bonded and can be used by simply winding like a hub 12 using a band.

5 is a perspective view showing a driving magnet according to another embodiment of the present invention, the driving magnet 21 is embedded at intervals in the fixing band 211 of a rubber material having an elastic restoring force having a long band shape, Extension ribs 212 are formed on both sides of the fixing band 211 in the width direction, and one side of the extension ribs 212 extends from the fixing band 211 and the fixing band 211. When the plurality of coupling holes 213 are formed in the extension ribs 212 extending from the second side, and the driving magnet 21 is wound around the shaft 11 on the other side in the longitudinal direction of the extension ribs 212, The coupling protrusion 214 fastened to the coupling hole 213 is protruded on both sides.

In the above embodiment, the driving magnet 21 can be more easily mounted on the shaft 11. The extension rib 212 extended around the fixing band 211 in which the driving magnet 21 is embedded is wound around the shaft. The coupling hole 213 of the) is to be fixed to the opposite coupling protrusion 214.

At this time, the coupling protrusion 214 is preferably placed on both sides to enable a more robust fixing.

Figure 6 is a perspective view showing a body according to another embodiment of the present invention, the wheel light (2) is mounted two but the body 22 is recessed in an arc shape in close contact with a portion of the outer diameter surface of the hub (12) Hinge for rotatably connecting the recessed contact portion 224, the rubber pad 225 seated on the recessed contact portion 224, and the body 22 disposed to be symmetrical to both sides of the hub 12 ( 226, and a locking hook 227 on the opposite side formed with the hinge 226, and a locking handle 228 for coupling and fixing the two bodies 22 in combination with the locking hook 227 The configuration is shown.

In the above embodiment, the recessed contact portion 224 is in close contact with the outer diameter surface of the hub 12 while the two wheel lights 2 are easily mounted when the two wheel lights 2 are mounted. Has a structure of preventing slipping.

In addition, one side is connected to the two bodies 22 by the hinge 226 and the other side has a structure that can be separated and coupled by the locking hook 227 and the locking handle 228 can be conveniently mounted structure It is to have.

In addition, the mounting of three to four wheel lights as well as two according to the shape of the body 22 may be made by various creative means that can be mounted to the shape of the body 22 and the hub 12.
