Description

Flywheel device driving method

The present invention relates to a method of driving a flywheel device, and more particularly to a method of driving a flywheel device having an unequal weight arrangement in a radial direction.

Please refer to FIG. 1 , which is a conventional flywheel device 9 . The flywheel device 9 includes a wheel 91 . The wheel 91 defines a shaft hole 92 in the center thereof. The wheel 92 is coupled to a rotating shaft (not shown). The flywheel device 9 can be rotated by the rotating shaft, wherein the weight distribution of the wheel 91 in the radial direction of the rotating shaft is equal, and when the wheel 91 rotates, a tendency to rotate around the rotating shaft is generated. This allows the flywheel device 9 to provide a torque.

However, due to the tolerance of the process, the weight distribution of the wheel 91 in the radial direction of the rotating shaft cannot be completely equal. Once the position of the center of gravity of the wheel 91 has an error, it deviates from the center of the shaft hole 92, and the wheel 91 is in the wheel 91. When the rotation is performed, an eccentric action is caused, so that the wheel 91 is unbalancedly rotated, and it is easy to derive axial pinching or vibration, and the torque that the flywheel device 9 can provide is reduced. In other words, the flywheel device 9 cannot provide a constant and stable torque, causing the rotating shaft to consume higher power to maintain the rotational speed of the flywheel device 9.

To this end, please refer to FIG. 2, which is a conventional modified flywheel device. The flywheel device includes a wheel 1 which is divided into a first block 11 and an eighth block along a circumferential direction. 18. A third block 13, a fourth block 14, a fifth block 19, a second block 12, a seventh block 17, and a sixth block 16, the first block 11 Second block 12, The weight ratio of the three blocks 13, the fourth block 14, the sixth block 16, the seventh block 17, the eighth block 18, and the fifth block 19 is 1:2:3:4:6:7: 8:9. Some embodiments of the improved flywheel device have been disclosed in the patent applications of the Republic of China on applications 102125664 and 104101214.

By having the first to fourth blocks 11, 12, 13, 14 and the sixth to fifth blocks 16, 17, 18, 19 have different weights, the respective blocks of the wheel 1 are in rotation The moment of inertia is different, and by properly arranging the blocks, the effect of the balance of rotation can be achieved when the wheel 1 is rotated. Since the weight of each block of the wheel 1 has a pre-existing difference, the wheel 1 is not susceptible to process tolerances. Therefore, the wheel 1 is less prone to eccentricity when rotated, and the wheel 1 can be balancedly rotated without deriving axial deflection or vibration, etc., so that the flywheel device can continuously and stably provide torque, with a lifting flywheel The effect of the torque output of the device.

Although the center of the wheel 1 can also be provided with a shaft joint 10 for coupling a rotating shaft, the wheel 1 can be rotated by the rotating shaft, but the rotating shaft can only be in the circumferential direction. The block applies the same torque; in other words, the rotating shaft cannot apply a large torque to the heavier block, and applies less torque to the lighter weight block, thus driving with the rotating shaft. When the wheel 1 is rotated, some of the input energy is still wasted, resulting in a limited effect of the flywheel device for increasing the torque output.

In view of the above, there is still a need for improvement in the driving method of the above-described conventional flywheel device to solve the problem of inefficient operation when the wheel 1 is driven by the rotating shaft.

Referring to FIG. 3, a driving method of the flywheel device according to an embodiment of the present invention can be performed by a driving device 2. The driving device 2 includes a first driving portion 21, a second driving portion 22 and a position sensor 23. The first driving portion 21 and the second driving portion 22 can be set In the outer circumference of the wheel 1 of the above-described modified flywheel device, it is known that the wheel 1 is divided into a first block 11 and an eighth block 18 in a circumferential direction (for example, clockwise or counterclockwise). a third block 13, a fourth block 14, a fifth block 19, a second block 12, a seventh block 17, and a sixth block 16. Wherein, the wheel 1 is circular, and the first to fourth blocks 11, 12, 13, 14 and the sixth to fifth blocks 16, 17, 18, 19 divide the wheel 1 into The arbitrarily arranged octaves are such that each of the blocks occupies 45° in the circumferential direction, and the first driving portion 21 and the second driving portion 22 can be disposed at 90° in the circumferential direction. The weight ratio of the first, second, third, fourth, sixth, seventh, eighth and fifth blocks 11, 12, 13, 14, 16, 17, 18, 19 forms 1:2:3 :4:6:7:8:9.

When the first driving portion 21 faces the eighth block 18, the second driving portion 22 may be formed toward the fourth block 14; similarly, when the first driving portion 21 faces the third block 13 The second driving portion 22 will be formed toward the fifth block 19. According to this, when the first driving portion 21 faces the eighth block 18 and the third block 13, the second driving portion 22 can be formed toward the fourth block 14 and the fifth block 19. between.

In the embodiment, the first driving portion 21 and the second driving portion 22 are each an electromagnet, wherein the first driving portion 21 is correspondingly provided with a first magnet 211, and the first magnet 211 is disposed on the first portion Between the eighth block 18 and the third block 13; the second driving portion 22 is correspondingly provided with a second magnet 221 disposed between the fourth block 14 and the fifth block 19 .

The position sensor 23 is configured to sense the relative positions of the first driving portion 21 and the second driving portion 22 and the wheel 1. In detail, the position sensor 23 senses whether the first driving portion 21 faces between the eighth block 18 and the third block 13; or senses whether the second driving portion 22 faces the first Between the four blocks 14 and the fifth block 19. For example, since the first magnet 211 is disposed between the eighth block 18 and the third block 13 in this embodiment, the position sensor 23 can be a Hall sensing element (Hall). Sensor), and the position sensor 23 The first block 211 can be disposed between the eighth block 18 and the third block 13 for sensing the first magnet 211. When the position sensor 23 senses the first magnet 211, it can be determined that the first driving portion 21 is oriented between the eighth block 18 and the third block 13; The driving portion 21 and the second driving portion 22 are disposed at a difference of 90°, and thus the second driving portion 22 is oriented between the fourth block 14 and the fifth block 19.

By making the first magnet 211 and the second magnet 221 have different polarities, it is possible to ensure that the position sensor 23 can correctly sense the first magnet 211. Similarly, the position sensor 23 can also be disposed between the fourth block 14 and the fifth block 19 for sensing the second magnet 221. Alternatively, the driving device 2 may also be provided with a plurality of position sensors 23, for example between the eighth block 18 and the third block 13 and the fourth block 14 and the fifth block 19, respectively. A position sensor 23 is disposed therebetween. The first magnet 211 and the second magnet 221 can have the same polarity. When the two position sensors 23 respectively sense the first magnet 211 and the second magnet 221, the first magnet 211 can be determined. A driving portion 21 is disposed between the eighth block 18 and the third block 13; and the second driving portion 22 is oriented between the fourth block 14 and the fifth block 19.

It can be seen that the position sensor 23 can have different installation positions or numbers, and can correctly sense the relative positions of the first driving portion 21 and the second driving portion 22 and the wheel 1. Therefore, the driving device 2 used in the driving method of the flywheel device of the embodiment is not limited thereto.

The driving method of the flywheel device of the embodiment is to sense whether the first driving portion 21 faces the eighth block 18 and the third block 13 by the position sensor 23 of the driving device 2; or sense the Whether the second driving portion 22 faces between the fourth block 14 and the fifth block 19. When the sensing result of the position sensor 23 is YES, the driving device 2 controls the first driving portion 21 to apply a torque between the eighth block 18 and the third block 13; The second driving portion 22 is controlled to apply a torque between the fourth block 14 and the fifth block 19.

More specifically, when the sensing result of the position sensor 23 is YES, the first driving portion 21 is oriented between the eighth block 18 and the third block 13, due to the eighth block The first magnet 211 is disposed between the 18 and the third block 13. The driving device 2 can control the first driving portion 21 to generate the same magnetic pole as the first magnet 211, so that the first driving portion 21 and the first driving portion 21 A repulsive force is generated between the first magnets 211. The first driving portion 21 and the wheel 1 may have an angle θ between a radial direction between the eighth block 18 and the third block 13. The angle is not equal to zero, and thus the first driving portion The repulsive force between the 21 and the first magnet 211 can form a torque that drives the rotation of the wheel 1.

On the other hand, the second driving portion 22 is disposed between the fourth block 14 and the fifth block 19, and the second magnet is disposed between the fourth block 14 and the fifth block 19. 221, the driving device 2 can control the second driving portion 22 to generate the same magnetic pole as the second magnet 221, and generate a repulsive force between the second driving portion 22 and the second magnet 221. The second driving portion 22 can also have an angle that is not equal to zero in the radial direction between the fourth block 14 and the fifth block 19 with the wheel 1, so the second driving portion 22 and the The repulsive force between the second magnets 221 may also form a torsion force that drives the rotation of the wheel 1.

The driving method of the flywheel device of the embodiment applies a torque between the eighth block 18 and the third block 13 and between the fourth block 14 and the fifth block 19 through the driving device 2, respectively. The wheel 1 can be driven to rotate. Referring to FIG. 4, when the wheel 1 is rotated, the first driving portion 21 is not facing between the eighth block 18 and the third block 13 (ie, the second driving portion 22 is not facing the first portion). When the fourth block 14 is between the fourth block 19 and the fifth block 19, the sensing result of the position sensor 23 is negative, and the driving device 2 controls the first driving portion 21 and the second driving portion 22 to suspend the pair. The wheel 1 is torqued. In this embodiment, the position of the first magnet 211 or the second magnet 221 of the wheel 1 is affected by the magnetic force. However, in order to prevent the magnetic pole of the first driving portion 21 from affecting the second magnet 221 Or the magnetic pole of the second driving portion 22 affects the first magnet 211, and the driving device 2 can control the first driving portion 21 and the second driving The portion 22 stops generating the magnetic poles, and the first driving portion 21 and the second driving portion 22 are surely suspended from applying torque to the wheel 1 to avoid affecting the operation of the wheel 1.

Referring to FIG. 3, when the wheel 1 is rotated 360°, the first driving portion 21 is again directed between the eighth block 18 and the third block 13 (ie, the second driving portion). 22, when facing again between the fourth block 14 and the fifth block 19), the driving method of the flywheel device of the embodiment may repeat the above steps to again the eighth block 18 and the third block 13 Torque is applied between the fourth block 14 and the fifth block 19, whereby the wheel 1 will be driven by the drive unit 2 to continue operation.

The driving method of the flywheel device according to the embodiment of the present invention can repeatedly overlap the eighth block 18 and the third block 13 and the fourth block 14 and the fifth block 19 through the driving device 2 by the above steps. Torque is applied between them to drive the wheel 1 to continue to operate. Wherein, the eighth block 18 and the fifth block 19 are the two most heavily weighted blocks among the eight blocks of the roulette 1, and the eighth block 18 and the third block 13 The weight difference is equal to the weight difference between the fifth block 19 and the fourth block 14, so that the eighth block 18 and the third block 13 and the fourth area are transmitted through the driving device 2. A torque is applied between the block 14 and the fifth block 19 to ensure stable rotation of the wheel 1 after the force is applied, and the torque outputted by the driving device 2 is used to drive the wheel 1 to avoid the driving device. The input energy of 2 is wasted.

According to the foregoing steps, the following describes in detail the features of the driving method of the flywheel device of the embodiment of the present invention and explains one by one:

Referring to FIGS. 3 and 4, in the foregoing step, the driving device 2 drives the wheel 1 to rotate in a clockwise direction (in accordance with the drawing), but please refer to FIG. The driving device 2 can also drive the wheel 1 to rotate in a counterclockwise direction (in terms of the drawing). For example, the driving device 2 can control the first driving portion 21 to generate a magnetic pole different from the first magnet 211, so as to generate a suction force between the first driving portion 21 and the first magnet 211; similarly, The driving device 2 can control the second driving portion 22 to be different from the second magnet 221 The magnetic pole generates a suction force between the second driving portion 22 and the second magnet 221, whereby the driving device 2 can drive the wheel 1 to rotate in a counterclockwise direction. Therefore, the invention does not limit the direction of rotation of the wheel 1.

In the foregoing step, the first driving portion 21 (the second driving portion) is further formed by causing the first driving portion 21 (the second driving portion 22) to form an angle not equal to zero with the radial direction of the wheel 1. 22) A repulsive force or suction force with the first magnet 211 (second magnet 221) may form a torsion force that drives the rotation of the wheel 1. For example, as shown in FIG. 6, the first driving portion 21 may be provided with a first magnet 211 and a third magnet 212. The first magnet 211 is disposed in the eighth block 18, and the third magnet is disposed. The second magnet 211 and the third magnet 212 have different polarities. The second driving unit 22 can be provided with a second magnet 221 and a fourth magnet 222 at the same time. The second magnet 221 is disposed on the fourth block 14 , the fourth magnet 222 is disposed on the fifth block 19 , and the second magnet 221 and the fourth magnet 222 have different polarities.

Thereby, the first driving portion 21 and the second driving portion 22 can be parallel to the radial direction of the wheel 1 respectively; that is, the first driving portion 21 (the second driving portion 22) and the wheel 1 The angle of the radial direction can be zero. When the sensing result of the position sensor 23 is YES, the driving device 2 can control the first driving portion 21 (the second driving portion 22) to generate the same magnetic pole as the first magnet 211 (the second magnet 221). a repulsive force is generated between the first driving portion 21 (the second driving portion 22) and the first magnet 211 (the second magnet 221), and a third force is generated between the first driving portion 21 (the second magnet portion 221) and the third magnet 212 (the fourth magnet 222). Suction, so that the first driving portion 21 (second driving portion 22) can respectively repel the first magnet 211 and suck with the third magnet 212 to form a torque that drives the rotation of the wheel 1, thereby driving the The wheel 1 rotates in a clockwise direction. Similarly, the driving device 2 can also control the first driving portion 21 (the second driving portion 22) to generate a magnetic pole different from the first magnet 211 (the second magnet 221), so that the first driving portion 21 (the first driving portion 21) A driving force is generated between the second driving portion 22) and the first magnet 211 (the second magnet 221), and the third magnet 212 is simultaneously A repulsive force is generated between the four magnets 222). Therefore, the first driving portion 21 (the second driving portion 22) may be respectively attracted to the first magnet 211 and repel the third magnet 212 to form the driving wheel. The rotating torque of the disk 1 drives the disk 1 to rotate in a counterclockwise direction.

In the foregoing steps, the first driving portion 21 and the second driving portion 22 of the driving device 2 are each an electromagnet. However, as shown in FIG. 7, the driving method of the flywheel device of the embodiment of the present invention is transparent. The other driving device 2 ′ also includes a first driving portion 21 and the second driving portion 22 , and the first driving portion 21 and the second driving portion 22 can each be a nozzle. Thereby, the first driving portion 21 can apply a torque between the eighth block 18 and the third block 13 by spraying the fluid; meanwhile, the second driving portion 22 can also be sprayed. The fluid applies a torsion between the fourth block 14 and the fifth block 19. In addition, the wind receiving portion between the eighth block 18 and the third block 13 of the wheel 1 and the wind between the fourth block 14 and the fifth block 19 of the wheel 1 can also be received. At each of the portions, a wind blocking member is disposed to block the jet flow, thereby improving the driving efficiency of the jet stream to the wheel 1.

In addition, the position sensor 23 of the driving device 2 is a Hall sensing element for sensing the permanent magnet, and the first driving portion 21 and the second driving portion 22 of the other driving device 2' do not need to be provided with permanent magnets. Therefore, the position sensor 23 of the other driving device 2 ′ can be a light sensor, and the position sensor 23 can correspondingly set a reflector 231 on the outer circumference of the wheel 1 . Thereby, the position sensor 23 can sense the retroreflective sheet 231, and thereby sense the relative positions of the first driving portion 21 and the second driving portion 22 and the wheel 1.

In summary, the driving method of the flywheel device according to the embodiment of the present invention is applied to the eighth block 18 and the third block 13 of the wheel 1 of the conventional modified flywheel device through the driving device 2 and the fourth block 14 Torque is applied between the fifth block 19 to drive the rotation of the wheel 1 to ensure stable rotation of the wheel 1 after the force is applied, and the torque outputted by the driving device 2 is used to drive the wheel 1 The input energy of the driving device 2 is prevented from being wasted. When the wheel 1 is driven by a rotating shaft, the torque applied by the rotating shaft to each block cannot be distributed, resulting in The input energy of the rotating shaft portion is wasted, and the driving method of the flywheel device of the embodiment can surely improve the driving efficiency of the wheel 1 to save the energy required for driving the wheel 1.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
