Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a badminton shuttlecock that generates and emits light by magnetic force according to a first embodiment of the present invention, and in a badminton shuttlecock comprising a rubber elastic part 31 and a wing part 35 connected to the rubber elastic part 31, The inside of the rubber elastic portion 31 has a hollow portion 22 (see FIGS. 3A and 3B), the front surface is provided with an air suction passage 21, the hollow portion 22 of the rubber elastic portion 31. The power generation unit 32 for generating electricity is attached to the rotary blade 33 is rotated by the air sucked, the light generating element 34 for emitting light with electricity generated in the power generation unit 32 is formed It is.

Here, the power generation unit 32 is located on the fixed shaft 30 fixed to the support 29 in the rubber elastic portion 31.

When the badminton shuttlecock of the present invention configured as described above is blown by a racket and blown to an opponent athlete, air is sucked into the air suction path 21 of the rubber elastic part 31, and the sucked air is generated by the power generation part 32. Rotating the rotor blade 33 to generate electricity,

At the same time, the generated electricity drives the light generating element 34 to emit light from the badminton shuttlecock, so that badminton competitions can be enjoyed even in a dark room where no lights or lights are formed at night.

Therefore, in the badminton shuttlecock to which the conventional battery is applied, the magnetic power generation may not be implemented. In the present design, the badminton shuttlecock capable of generating electricity by generating electricity by magnetic force may be implemented.

Here, the first embodiment of the present invention, as shown in Figure 1, the light generating element 34 at the tip of the power generation unit 32, and rotates with the rotary blade 33 to emit light.

Specific operation principle thereof will be described in FIG.

FIG. 2 is a perspective view of a portion of the power generation unit of FIG. 1, wherein the power generation unit 40 includes a cylindrical case 42 having a rotary blade 41 attached to a surface thereof; A coil 45 wound in a cylindrical shape on an inner surface of the cylindrical case 42; A fixed shaft 44 fixed to the inner support 46 of the rubber elastic part; It is composed of a plurality of permanent magnets 43 attached to the fixed shaft 44.

When the rotary blade 41 is rotated by the wind, the power generation unit is also rotated with the cylindrical case 42.

When the cylindrical case 42 rotates, the coil 45 attached to the inner surface of the cylindrical case 42 also rotates so that the coil 45 interlinks with the magnetic flux generated by the permanent magnet 43.

At this time, when the coil 45 bridges the magnetic flux of the permanent magnet 43, a current is generated in the coil 45 according to Fleming's right hand rule.

Therefore, when the rotary blade 41 receives the wind and rotates, the power generation unit 40 also rotates to generate electricity.

Therefore, the light generating element 34 of the first embodiment of the present invention is mounted on the front end of the power generation unit 32 is mounted on the front surface of the cylindrical case 42 shown in Fig. 2, and the fixed shaft 44 is rubber If it is fixed to the inner support 44 of the elastic portion is implemented.

Here, the light generating element 34 may be mounted on the rear or side of the cylindrical case 42, and when mounted on the rear or side, emitting light emitted from the light generating element 34 to the outside of the badminton shuttlecock. To this end, the rubber elastic portion 31 is implemented by forming a light emitting hole in the corresponding area.

4 is a badminton shuttlecock that generates light by generating magnetic force according to a second embodiment of the present invention, and connects a light generating element 34 to a rotating shaft 36 that receives the rotational force of a rotary blade, thereby generating light by rotating the rotary blade. The generator can be rotated.

In more detail, with reference to Figure 2, a cylindrical coil wound around the inner surface is formed, and a cylindrical case attached to the inside of the rubber elastic portion 31; A rotating shaft penetrating through the cylindrical case 42 and rotated by a rotary blade mounted at the tip, and having a permanent magnet attached to the inside of the coil; The insertion groove 44a into which the rotary shaft can be inserted is provided in the support formed inside the rubber elastic part,

Referring to FIG. 5, a separation preventing projection 36a is formed on the rotation shaft 36 so that the rotation shaft 36 is not separated from the insertion groove 44a, and is attached to the support 44 formed inside the rubber elastic part. When the separation prevention jaw (36a) is configured to be inserted into the groove portion (37a) of the guide member 37, the second embodiment of the present invention can be implemented.

FIG. 6 is a perspective view illustrating a state in which a ring capable of connecting a string to a badminton shuttlecock that emits light by generating magnetic force of the present invention is mounted. 60 is mounted, the rope 60 is connected to fix the string, and when holding the rope at night to turn, the air generated by the rotation of the rotation is sucked into the rubber elastic part 31 to generate power.

Therefore, the badminton shuttlecock emits light in the direction of holding and turning, so that children and adolescents can enjoy it as if playing folk rats.

As described above, the present invention is capable of emitting light by generating electricity by magnetic force without having complicated circuit boards and batteries, so that badminton games can be enjoyed at night and in a dark room.

Although the present invention has been described in detail only with respect to specific examples, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical scope of the present invention, and such modifications and modifications belong to the appended utility model registration claims.
