DETAILED DESCRIPTION
[0026] The following is combined with Figure 1-2 This application is described in further detail.
[0027] The present application embodiment discloses a flywheel capable of improving wind resistance. Figure 1 and Figure 2The flywheel capable of improving wind resistance comprises a flywheel body 1, which is rotatable. In the present embodiment, the flywheel is arranged in a hysteresis motor. In addition, the flywheel can also be arranged in other devices in need. An obstacle 2 is fixed on the flywheel body 1 in an integrated manner. At least one obstacle 2 is arranged. When a plurality of obstacle 2 are arranged, the plurality of obstacle 2 are evenly distributed around the axis of the flywheel body 1. The obstacle 2 is in the shape of a raised strip and is mainly used to improve the wind resistance of the flywheel body 1. An output part 7 is arranged at the bottom of the obstacle 2. The output part 7 comprises a first rod 8 and a first gear 9. The two ends of the first rod 8 are respectively fixed to the first gear 9 and the flywheel body 1. , and the first rod 8, the first gear 9, and the flywheel body 1 are coaxially arranged. A driving part is arranged in the hysteresis motor. In this embodiment, the driving part is a stator assembly in the hysteresis motor. The driving part is arranged at the bottom of the flywheel body 1 and is used to drive the flywheel body 1 to rotate. The first rod 8 is penetrated inside the stator assembly. After the stator assembly is energized, it can drive the first rod 8 to rotate, and at the same time drive the flywheel body 1 and the first gear 9 to rotate. The hysteresis motor is also provided with a transmission part 6 and an output part 7. The transmission part 6 is connected to the input part 5, and the output part 7 is connected to the transmission part 6. The rotation of the first gear 9 is transmitted to the output part 7 through the transmission part 6, thereby outputting energy.
[0028] Reference Figure 1 and Figure 2 The output part 7 includes a first output gear and a second output gear 11. The first output gear 10 is placed inside the hysteresis motor, and the second output gear 11 is placed outside the hysteresis motor and serves as the output part 7. The first output gear 10 and the second output gear 11 are coaxially arranged. The transmission part 6 includes a plurality of gears, and the plurality of gears transmit the rotation of the first gear 9 to the first output gear 10. The transmission part 6 includes a first main transmission gear 14, a first sub-transmission gear 15, a second main transmission gear 16, and a second sub-transmission gear 17. The first main transmission gear 14 and the first sub-transmission gear 15 are coaxially arranged, and the diameter of the first main transmission gear 14 is larger than that of the first sub-transmission gear 1 5 diameter; the second main transmission gear 16 and the second sub-transmission gear 17 are coaxially arranged, and the diameter of the second main transmission gear 16 is larger than that of the second sub-transmission gear 17; the first main transmission gear 14 is meshed with the first gear 9, the first sub-transmission gear 15 is meshed with the second main transmission gear 16, and the second sub-transmission gear 17 is meshed with the first output gear 10, so the first rod 8 drives the first gear 9 to rotate, and the first gear 9 drives the first output gear 10 to rotate through the first main transmission gear 14, the first sub-transmission gear 15, the second main transmission gear 16, and the second sub-transmission gear 17, and drives the second output gear 11 to rotate, so as to transmit energy to the outside of the hysteresis motor.
[0029] Reference Figure 1 and Figure 2The output portion 7 also includes a torsion spring 12, which is disposed at the first output gear 10. In this embodiment, the torsion spring 12 is disposed between the first output gear 10 and the second output gear 11, that is, disposed on a rotating shaft shared by the first output gear 10 and the second output gear 11. The torsion spring 12 is mainly used to drive the first output gear 10 and the second output gear 11 to reset after rotation.
[0030] Reference Figure 1 and Figure 2 A first guide surface 4 is provided on the obstruction portion 2, and the first guide surface 4 is arranged in the opposite direction of the rotation direction of the flywheel body 1 driven by the driving portion 13, that is, when the driving portion 13 drives the flywheel body 1 to rotate, due to the influence of the first guide surface 4, the wind resistance will not cause a large interference to the rotation of the flywheel body 1; when the torsion spring 12 drives the flywheel body 1 to rotate, since there is no first guide surface 4 in its rotation direction, the rotation speed is slowed down under the action of wind resistance, thereby minimizing the damage to the gear caused by the faster rotation speed and improving the service life.
[0031] Reference Figure 1 and Figure 2 The bending direction of the obstruction part 2 is toward the direction in which the first guide surface 4 is opened. Therefore, when the driving part 13 drives the flywheel body 1 to rotate, the obstruction part 2 plays a role in guiding the wind, further reducing the interference of wind resistance on the rotation of the flywheel body 1; when the torsion spring 12 drives the flywheel body 1 to rotate, due to its curved setting, it can collect wind, further increase wind resistance, and further reduce the damage to the gear caused by excessive rotation speed.
[0032] Reference Figure 1 and Figure 2 A plurality of pneumatic grooves 3 are provided on the flywheel body 1, and the pneumatic grooves 3 penetrate the flywheel body 1 along the axial direction of the flywheel body 1. The pneumatic grooves 3 include a first through groove and a second through groove, and the first through groove and the second through groove are staggered, and the first through groove is curved, and the obstruction part 2 is arranged at the first through groove, and the vertically arranged side wall of the obstruction part 2 is attached to the side wall of the first through groove, and the bending direction of the first through groove is the same as that of the obstruction part 2; in addition, the flywheel body 1 is integrally formed by injection molding, and the injection molding method ensures the concentricity and balance of the flywheel body 1.
[0033] The implementation principle of a flywheel capable of improving wind resistance in an embodiment of the present application is as follows: when the coil is energized, the flywheel body 1 and the first rod 8 will rotate in the direction indicated by the arrow A1; when the coil is de-energized, due to the action of the torsion spring 12, the flywheel body 1 and the first rod 8 will rotate in the direction indicated by the arrow A2. The torsion spring 12 is configured to reversely rotate the output shaft when power is off, thereby causing the flywheel body 1 to reversely rotate. During the reverse rotation process, due to the presence of the obstruction part 2, the wind resistance of the flywheel body 1 during rotation is increased, thereby reducing the reverse rotation speed of the flywheel body 1 and reducing the possibility of gear damage.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
