Abstract

The invention discloses a light-emitting diode (LED) yo-yo, which comprises a hollow winding post, wherein the two sides of the winding post are fixedly provided with wheel discs; a coil capable of freely rotating around the axis of the winding post is arranged inside the winding post; all winding surfaces of the coil are parallel to the axis of the winding post; the output end of the coil is electrically connected with an LED through an LED control chip; and the inner wall of the winding post is fixedly provided with a pair of opposite arc-shaped permanent magnets with different poles. The LED yo-yo can automatically generate electricity with higher power in the using process without addition of batteries, so that multi-LED colored illumination is supported.

Description

A kind of LED yo-yo

Technical field

The present invention relates to the LED field, especially relate to a kind of LED yo-yo of the LED of having illumination functions.

Background technology

Yo-yo is a kind of common toy, receives liking of children especially, and it mainly comprises the wrapping post of a bilateral pulley sheaves, twines backguy on this wrapping post, and the pull up and down through backguy can drive the wheel disc fast rotational, reaches entertainment effect thus.

For the ease of using, and have better appreciation effect, be provided with LED in the at present more yo-yo, make it have gorgeous illuminating effect, and in order to support LED luminous, need powered battery simultaneously again, then comparatively inconvenience when changing battery at night; For the other yo-yo, utilize the vibration generating device generating, its generating efficiency is lower, can't support that many LED are luminous, and expression effect comparatively limits to.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide a kind of LED yo-yo, this LED yo-yo need not to add battery, can in use carry out the generating voluntarily of more high-power ground, thus support many LED to dazzle color picture bright.

The technical solution adopted for the present invention to solve the technical problems is: this LED yo-yo comprises the hollow wrapping post, and these wrapping post both sides are fixed with wheel disc; Said wrapping post inside is provided with a coil that can rotate freely around the wrapping post axis, each circle coiling plane of said coil all with the wrapping post parallel axes, and the output of said coil is electrically connected LED through the LED control chip; Said wrapping post inwall is fixed a pair of heteropole arc-shaped permanent magnet in opposite directions.

As preferably, said coil two ends are provided with rotating shaft, and this coil is realized being rotatably assorted through said rotating shaft and said wheel disc.

As preferably, said coil inside has balancing weight, and its gross weight is greater than the gross weight of said wrapping post and wheel disc; Thereby make wrapping post and wheel disc when rotated; Because inertia difference produces bigger speed discrepancy with said coil, promotes the speed of coil cutting magnetic line.

As the further improvement of above-mentioned optimal way, said balancing weight departs from the axis setting of said coil, thereby makes coil under the gravity effect, keeps the downward position of balancing weight, makes it be difficult for rotating.

As preferably, said LED is arranged on the axis body of said rotating shaft, makes itself and rotating shaft, coil static relatively, not fragile.

Beneficial effect of the present invention is: this LED yo-yo is carried out pull up and down through backguy to wrapping post in use, and wrapping post and wheel disc are with fast rotational; With the fixing said a pair of heteropole arc-shaped permanent magnet in opposite directions of said wrapping post inwall also with fast rotational; Because said coil can rotate freely around said wrapping post axis, therefore, will produce bigger speed discrepancy between coil and the wrapping post; Thus; Coil is the fly-cutting magnetic line of force, output voltage, and light each LED through said LED control chip; Because the generating efficiency of pure cutting magnetic line is much larger than jejune vibration generating device still, this LED yo-yo need not to add battery, can in use carry out the generating voluntarily of more high-power ground, thus support many LED to dazzle color picture bright.

Description of drawings

Fig. 1 is the vertical profile structure chart of an embodiment of a kind of LED yo-yo of the present invention.

Fig. 2 is that the A-A of Fig. 1 embodiment is to cutaway view.

Among the figure: 2, coil; 3, rotating shaft; 4, LED; 5, arc-shaped permanent magnet; 10, wheel disc; 11, wrapping post.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In Fig. 1, embodiment shown in Figure 2, this LED yo-yo comprises hollow wrapping post 11, and these wrapping post 11 both sides are fixed with wheel disc 10; Said wrapping post 11 inside are provided with a coil 2 that can rotate freely around wrapping post 11 axis, each circle coiling plane of said coil 2 all with wrapping post 11 parallel axes, and the output of said coil 2 is electrically connected LED 4 through the LED control chip; Said wrapping post 11 inwalls are fixed a pair of heteropole arc-shaped permanent magnet 5 in opposite directions.

Said coil 2 is realized being rotatably assorted through following mode and said wrapping post 11: this wrapping post 11 is passed in a rotating shaft 3, and stretches out wrapping post 11 two ends, and rotating shaft 3 two ends pierce on the bearing in the said wheel disc 10, realizes being rotatably assorted; Because said wheel disc 10 is fixedly connected with wrapping post 11, so said coil 2 has also been realized being rotatably assorted with wrapping post 11.

Above-mentioned LED yo-yo, said coil 2 inside have balancing weight, and its gross weight is greater than the gross weight of said wrapping post 11 with wheel disc 10; Thereby make wrapping post 11 and wheel disc 10 when rotated; Because inertia difference produces bigger speed discrepancy with said coil 2, promotes the speed of coil cutting magnetic line; In order further to make coil 2 be difficult for rotating, said balancing weight departs from the axis setting of said coil 2, thereby makes coil 2 under the gravity effect, keeps the downward position of balancing weight.

Above-mentioned LED yo-yo, said LED4 is arranged on the axis body of said rotating shaft 3, makes itself and rotating shaft 3, coil 2 static relatively, not fragile.

Above-mentioned LED yo-yo is carried out pull up and down through backguy to wrapping post 11 in use, and wrapping post 11 and wheel disc 10 are with fast rotational; With the fixing said a pair of heteropole arc-shaped permanent magnet 5 in opposite directions of said wrapping post 11 inwalls also with fast rotational; Because said coil 2 can rotate freely around said wrapping post 11 axis, therefore, will produce bigger speed discrepancy between coil 2 and the wrapping post 11; Thus; Coil 2 is the fly-cutting magnetic line of force, output voltage, and light each LED4 through said LED control chip; Because the generating efficiency of pure cutting magnetic line is much larger than jejune vibration generating device still, this LED yo-yo need not to add battery, can in use carry out the generating voluntarily of more high-power ground, thus support many LED to dazzle color picture bright.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
