Description

Induction luminous core wheel

The utility model relates to the luminous wheel of a kind of energy, particularly a kind of induction luminous core wheel.

Chinese patent CN-2266528Y discloses a kind of " self luminous wheel arrangement ", it mainly by circuit card and this circuit card be provided with one be contained in the shell fragment group the dc-battery group with link to each other with battery and can switch on and luminous luminary is formed, circuit card is contained in the wheel pilot trench of band groove, groove covers euphotic cover outward, during wheel turns, luminous by shell fragment contact conducting luminary.This luminous wheel needs powered battery, and service life is short, cost is high.

The purpose of this utility model is to provide a kind of to need not additional power source and the automatic luminous induction luminous core wheel of electrogenesis of energy for the deficiency that solves above-mentioned technology,

In order to achieve the above object, the designed induction luminous core wheel of the utility model mainly comprises wheel core housing, bearing, magnetic induction coil and luminotron, be characterized on the interior ring of bearing, be fixed with multi-pole magnet, be fixed with the wheel core housing on the cylindrical of bearing, and multipole irony framework is arranged at wheel core housing internal fixation, and induction coil wraps in the multipole irony framework, and luminotron links to each other with the mouth of magnetic induction coil.According to the requirement of the luminotron of varying number, the number of magnetic poles of multi-pole magnet is between 10 to 24 utmost points, and the number of poles of multipole irony framework is corresponding with it.

After the resulting induction luminous core wheel of the utility model is made luminous wheel, have and do not have friction, characteristics such as life-span length, no use cost, and simple in structure, productive costs is low, is used for toy, can excite the understanding of children, to promote its desire for knowledge to the luminous generating knowledge of entertaining.Can be widely used in luminous wheel and amusement caution on the equipment such as Kickboard Scooter, dry skating ice skate, perambulator, bicycle, Manpower-aid bicycle, exercise and fitness equipment according to the selection of different size and glow color.

Fig. 1 is the utility model structural representation;

Fig. 2 is that multi-pole magnet is provided with structural representation;

Fig. 3 is an elementary diagram.

Below by embodiment, in conjunction with the accompanying drawings, the utility model is further described.

As shown in Figure 1, a kind of induction luminous core wheel that present embodiment is described, it mainly comprises wheel core housing 1, bearing 2, magnetic induction coil 3 and luminotron 4, be characterized on the interior ring 5 of bearing 2, be fixed with multi-pole magnet 6, be fixed with wheel core housing 1 on the cylindrical 7 of bearing 2, and multipole irony framework 8 is arranged at wheel core housing 1 internal fixation, induction coil 3 wraps in the multipole irony framework 8, and luminotron 4 links to each other with the mouth of magnetic induction coil 3.When wheel rotates on the ground, because multi-pole magnet 6 is fixed on the interior ring 5 of bearing 2, therefore it is static relatively, and because multipole irony framework 8 and wrap in in-to-in magnetic induction coil 3 and be fixed on the cylindrical of bearing 2, therefore, will rotate with the rotation of wheel, as shown in Figure 2, when multi-pole magnet polarity dots position during over against the metal pole piece 9 of required multipole irony framework 8, because two adjacent metal pole pieces 9 are magnetized to the strongest on the multipole irony framework 8; When multi-pole magnet 6 polarity dots rotated position are middle to adjacent two metal pole pieces, the magnetic-field intensity that this metal pole piece 9 constitutes is because the magnetization distance becomes the counteracting of far away and adjacent pole, its intensity is reduced to minimum, when the wheel continuous rotation, can produce the magnetic field of many groups gradual change on the multipole irony framework 8, the magnetic induction coil 3 that wraps in this moment in the multipole irony framework 8 produces induced electric motive force owing to the phenomenon of electromagnetic induction, as shown in Figure 3, after inserting light-emitting diode at the coil two ends, induced electric motive force can produce inducing current, triggers lumination of light emitting diode, according to required luminous what, can determine the multi-pole magnet 6 of different numbers of poles, to satisfy the demand of different occasions.
