Description

A luminescent wheel for bicycles}

The present invention relates to a light emitting wheel for a bicycle equipped with a light emitting diode that is turned on and emits light when driving. More specifically, the induction coil and magnet are formed on the inner circumferential surface of the wheel shaft casing and the outer circumference of the bicycle shaft to generate electricity along with the rotation of the wheel. The outer surface of the wheel member that is exposed to the outside, such as a wheel fixed plate coupled to the inner circumference of the rim constituting the wheel or the outer circumferential surface of the wheel shaft casing, the light emitting diode which is lighted by the electricity generated from the induction generator when the bicycle is running by mounting a small induction generator In particular, the present invention relates to a light emitting wheel for a bicycle, which makes it possible for anyone to easily find the location of a bicycle running at night, and at the same time, obtains an aesthetic effect.

Bicycles that have been used as auxiliary vehicles have already been widely used in most homes with the improvement of living standards. Today's bicycles are also used for students' commuting, but they are mainly used as auxiliary vehicles. It is used for recreation and exercise of adults such as children's play or mountain bike.

However, unlike the prevalence of bicycles, the use of bicycle-only roads is hardly achieved, and most bicycle users have no choice but to drive the roads.

Moreover, when driving at dark distances at night, it is not easy for the driver of the driving car to find the bicycle, and the risk of accidents due to accidental behavior, especially when children who lack the situation judgment of the surrounding environment, ride the bicycle. Becomes larger, the driver of the vehicle must know in advance how long the bicycle is running.

But. There are few devices for easy identification of bicycles that are driven at night, not daytime, and small luminous reflectors, which are attached to wheels or frames, cause some light emission by reflection when they receive light. It doesn't work.

In other words, the luminous reflector does not exhibit a special function during the day, and even at night, because the reflection effect is caused only by light incident from the outside, the function of identifying the bicycle to a third party is weak and is always exposed to safety accidents. there is a problem.

As described above, the present invention was devised to solve various problems of the conventional bicycle, which cannot be reliably recognized by a third party, such as a driver of the vehicle, that the bicycle is running. By attaching a light emitting diode that is turned on to the outer surface of the wheel member so that the light emitting diode is turned on when the bicycle is driven, not only a decorative effect but also a third party can clearly show the bicycle in operation, thus unintentionally causing accidents. It is an object of the present invention to provide a bicycle light emitting wheel that can be prevented.

That is, induction electricity is generated while the induction coil fixed to the inner circumferential surface of the wheel shaft casing rotates along the outer circumferential surface of the permanent magnet fixed to the outer circumferential surface of the wheel shaft when the bicycle is driven. The light emitting diode attached to the wheel member is turned on.

The purpose and detailed technical characteristics and effects of the present invention will be clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

First, look at the configuration of the induction generator and the light emitting diode to be the light emitting source of the light emitting wheel for the present invention through the exploded configuration diagram of the induction generator shown in FIG.

As shown in the drawing, the induction generator 1 has a cylindrical bobbin 11 having a flange 11A perpendicular to the axial direction and extending at both ends and having a hollow portion V, and an outer peripheral surface of the bobbin 11. The induction coil 12 wound in one direction and an inner surface 13A are in close contact with the outer surface of the bobbin flange 11A and a protective flange 13F for protecting the induction coil in close proximity to the outer circumferential surface of the induction coil 12. A plurality of magnetic force interrupting pins 13B are formed to extend in the axial direction on the edge and close to the inner circumferential surface of the bobbin hollow part V to continually crack the lines of magnetic force. A pair of bobbin casing 13 formed and a permanent magnet 14 fixed to the outer peripheral surface of the wheel shaft of the bicycle so as to be adjacent to the inner peripheral surface of the hollow portion V in the hollow portion V of the bobbin coupled to the casing 13. do.

In addition, a plurality of light emitting diodes connected to the induction coil 12 and turned on by being supplied with electricity are prominent in a human eye such as an outer surface of a wheel member exposed to the outside such as a rim, a wheel fixing plate, and a wheel constituting the wheel. Attached.

As shown in FIG. 2, which shows a schematic cross-sectional structure diagram of the wheel shaft and the wheel shaft casing in which the induction generator is assembled, a bearing B is interposed between the outer circumferential surface of the wheel shaft 21 and the inner circumferential surface of the wheel shaft casing 22, and the wheel shaft casing. Bolts D are coupled to both ends of the wheel shaft 21 in a state where both ends of the wheel 22 are blocked by the protective cover C, and the spokes 32 are coupled to the outer circumferential surfaces of both side ends of the wheel shaft casing 22 and have a central portion. It is a structure that is fixed to the wheel plate fixing plate 33 of the disc formed through-holes.

At this time, the bobbin 11, which the induction coil 12 is wound and protected by the bobbin casing 13, is fixed to the inner circumferential surface of the wheel shaft casing 22 and is fixed to the outer circumferential surface of the wheel shaft around the wheel shaft 21. 14) to rotate around.

Therefore, the magnetic force lines of the permanent magnets delivered to the induction coil side by the magnetic force interrupting pin 13B in close contact with the inner peripheral surface of the hollow part V of the bobbin 11 are repeatedly interrupted to generate induction electricity in the induction coil. Induction electricity is transmitted to the light emitting diode attached to the wheel member through a connecting line W extending out of the outer circumferential surface of the wheel shaft casing 22.

As described above, the plurality of light emitting diodes 15 connected to the induction generator mounted on the wheel shaft 21 and the wheel shaft casing 22 can be seen from the front view of the bicycle wheel 3 shown in FIGS. 3 to 5.
