Description

A kind of multi-functional ball game for exercising wrist

Technical field: the utility model relates to a kind of body-building recreation toy, particularly a kind of multi-functional ball game for exercising wrist with health care, amusement and generating effect.

Background technology: my company once filed an application and was granted to Patent Office of State Intellectual Property Office on May 29th, 2002 and gave the multi-functional ball game for exercising wrist that the Patent right patent No. is ZL02227862.1, it mainly comprises spherical shell, be placed on the annulus in the spherical shell, one rotating shaft holding is on annulus, in rotating shaft, adorn a rotor, also be fixed with magnet on the annulus, also be fixed with coil on the rotor, at least connect two light emitting diodes at the two ends of coil, described magnet is passed by the rotating shaft axle head on annulus, the coil stationary that is complementary with magnet near the position of magnet, comprises the magnetic field N of at least one group of magnet on the surface of the magnet relative with coil on rotor, the S utmost point.This ball game for exercising wrist can use palm by after the rotor at shell nozzle place is exposed in startup from top to bottom when using, utilize the rotation of wrist that rotor is quickened again, is similar to gyro, can produce the power rotation, and coil produces electric current, makes led lighting.But the magnet of this ball game for exercising wrist and the structure of coil are desirable not enough, and the electric power that coil produces uses in ball only, can not provide electric power to the external world, make ball game for exercising wrist interest and practicality relatively more dull.

Summary of the invention: the purpose of this utility model is to provide a kind of multi-functional ball game for exercising wrist that had not only had body-building, amusement function but also electric power can be provided to the external world.

The purpose of this utility model can be achieved as follows: this multi-functional ball game for exercising wrist, mainly comprise spherical shell, be placed on the annulus in the spherical shell, one rotating shaft holding is on annulus, in rotating shaft, adorn a rotor, it is characterized in that: it is homocentric and perpendicular to the magnet of rotating shaft with rotor that a circle is equipped with on the surface of described rotor, and the coil stationary that is complementary with magnet comprises magnetic field N, the S utmost point of at least one group of magnet on the surface of the magnet relative with coil on the magnetic core of base.

As further improvement of the utility model: the structure of the magnetic core of this multi-functional ball game for exercising wrist is general jar of type, and imperforation or opening are not more than 1.5MM on it, and the center does not have perforate, and cut surface is Internal Spherical Surface or plane.

As further improvement of the utility model: the coil of this multi-functional ball game for exercising wrist is connected with output port of power source through rectification, filtering, voltage stabilizing.

The utility model utilizes the power rotation of ball game for exercising wrist, make internal structure become a small generator, fixing coil is equivalent to the stator of generator on the housing, fixing magnet is equivalent to the rotor of generator on the rotor, magnet was fixed on the diameter circumference of the rotor centre of sphere and comprised the magnetic field N of one group of magnet at least, the S utmost point, coil stationary is on the magnetic core of housing base, like this no matter how rotor rotates, coil is the order cutting magnetic line always, thereby produce strong and sufficient stable induced voltage and electric current, because coil is fixed on the base, can draws supply terminals easily and provide electric power simultaneously to the external world.Therefore, this ball game for exercising wrist makes the structure of magnet and coil become better, the deficiencies in the prior art have been avoided, can provide sufficient and stable electric power to the external world, charge as small-sized electric instruments such as the mechanical, electrical moving shavers of adversary, make the function of ball game for exercising wrist realize better expansion, particularly for operation in the open air, go sightseeing and the situation of non-fixed power, the electric power that the utility model ball game for exercising wrist provides can be separated the matter of great urgency undoubtedly.In addition, in this ball game for exercising wrist housing, the two ends of coil equally also can connect light emitting diode, music electronic plate and loudspeaker etc., use the long-term exercise of this ball game for exercising wrist still can strengthen the strength of wrist and arm, strengthen the grip of palm and finger, promote the blood circulation of arm and even whole body, body health benefits, but so this ball game for exercising wrist body-building recreation not only, also integrate recreational, interest and practicality, coil is that brushless structure is drawn simultaneously, there is not wear to electrodes, can be durable in use, it is simple in structure, low cost of manufacture is well suited for the needs of different crowd.

Description of drawings:

Fig. 1 is the structural representation of the multi-functional ball game for exercising wrist of the utility model;

Fig. 2 is another schematic perspective view of the multi-functional ball game for exercising wrist of the utility model.

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:

In Fig. 1 and Fig. 2, the spherical shell of this ball game for exercising wrist is made of base 3 and loam cake 6, opening 7 is arranged on it, rotating shaft 8 holdings are on annulus 4, fixed rotor 9 in the rotating shaft, the fraction of this rotor can expose the opening of spherical shell, it is homocentric and perpendicular to the magnet 10 of rotating shaft with rotor that a circle is equipped with on the surface of rotor 9, the center of circle and the rotor that promptly should enclose magnet 10 die casting formed circle on rotor surface are homocentric, the circle of magnet formation simultaneously is vertical with rotating shaft, guaranteeing the concentricity of rotor, rotating shaft two axial ends 11 is passed on the annulus perforation 12 and is pressed on the base, and the coil 2 that is complementary with magnet is fixed on the magnetic core 1, magnetic core is fixed on the base, the structure of magnetic core is general jar of type, and imperforation or opening are not more than 1.5MM on it, and the center does not have perforate, cut surface is Internal Spherical Surface or plane, purpose is conveniently to process and improve its conversion efficiency, and the time spent can single magnetic core and magnet, coil is used, and needs use in pairs and need not resemble common jar type magnetic core.The magnetic field N, the S utmost point that comprise at least one group of magnet on the surface of the magnet relative, the N of this circle magnet, S with coil extremely can be non-individual body or magnet make subsection cross section N, even location that S is extremely alternate is set on the rotor surface.For ease of starting, have annular groove 13 on the magnet one, place the counterbore 14 of annular groove to get final product with an end of stay cord 15.Convenient for power supply output, on base, coil is connected with output port of power source after rectification, filtering, voltage stabilizing, can provide electric power for small-sized electric instruments such as mobile phone, electronic shavers by output port of power source.

In addition, in order to increase the interest of ball game for exercising wrist, the two ends of coil also are connected with loudspeaker with the music electronic plate, can insert various music in advance on the smart card, the needs that adapt to different crowd, during especially as present, not only can enjoy beautiful music but also can experience fine blessing, integrate body-building recreation especially.
