Abstract
Description
Technical Field
[0001] The invention relates to the field of gyromagnetic technology, in particular to a strong magnetic component and a gyromagnetic mechanism. Background Art
[0002] The gyromagnetic mechanism is a device designed based on the gyromagnetic effect, which controls or affects the material in the magnetic field by generating a rotating magnetic field. In the medical field, a rotating magnetic field of at least 600-1500 Gauss can be used in physical therapy equipment. A rotating magnetic field of 600-1500 Gauss can promote local blood circulation, relieve muscle tension, and reduce pain.
[0003] For example, the Chinese utility model patent with application number CN 202223370965.9, entitled A motor and magnetic therapy device with gyromagnetic function, comprises an outer shell, a metal inner shell, a main shaft, a driver and a magnetic device; the metal inner shell is fixedly arranged in the middle of the outer shell, bearings are respectively arranged at both ends of the metal inner shell, and the main shaft is mounted on the two bearings; the driver is located in the metal inner shell and is connected to the main shaft for transmission, the two ends of the main shaft respectively pass through two bearings to fix the magnetic device, and a spring is arranged between the magnetic device and the bearing at least at one end; a large magnetic steel abutting against the magnetic barrier sheet is provided on the other side of the large magnetic steel, and a metal gasket is provided on the other side of the large magnetic steel.
[0004] The magnetic therapy device in the above-mentioned prior art can effectively alleviate the vibration caused by the rotation of the motor and reduce the noise during operation, but the magnetic device therein is a single magnetic block. Compared with the spliced magnetic blocks of the same volume, its surface magnetic induction intensity is smaller and the magnetic field coverage range is also smaller. Correspondingly, the magnetic therapy effect is weaker.

[0011] As a preferred embodiment of the present invention, an upper cavity and a lower cavity are formed in the middle position of the strong magnetic component body. The upper cavity is located above the lower cavity, the diameter dimension of the upper cavity is larger than the diameter dimension of the lower cavity, and a fixing block is accommodated inside the upper cavity.
[0012] A gyromagnetic mechanism includes a strong magnetic component, a brushless motor, and a housing. The brushless motor is arranged directly below the strong magnetic component and controls the rotation or stillness of the strong magnetic component. The housing includes a base and an outer cover. The base is used to support the brushless motor and the strong magnetic component, and the outer cover is used to wrap the brushless motor and the strong magnetic component. One side of the base facing the brushless motor has a support column protruding upward. A cavity is formed inside the support column, and a notch is formed at the bottom of the support column.

The connecting shaft is accommodated in the lower cavity of the strong magnetic component, and the rotating shaft is accommodated in the cavity of the support column.
[0014] As a preferred embodiment of the present invention, the brushless motor further includes a suspension magnet, a fixed magnet, and an end cover. The end cover includes a mounting portion, a positioning portion, and a mounting notch. The mounting portion is accommodated in the notch of the support column. The suspension magnet is fixedly arranged at the lower end of the rotating shaft, and the fixed magnet is accommodated in the mounting notch.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention uses the splicing between the A magnets, B magnets, C magnet groups and D magnet groups, so that the magnetic induction intensity on the surface of the strong magnetic assembly is above 12,000 GS, the coverage radius of the magnetic field lines in the horizontal direction is about 50 cm, and the coverage height of the magnetic field lines directly above is about 50 cm. The height range and diameter range of the magnetic field are determined. In cooperation with the brushless motor, the range of the rotating magnetic field is limited, and the controllable rotating magnetic field can be better used for targeted magnetic therapy on the human body.
[0018] 2. The magnetic induction intensity on the surface of the strong magnetic assembly of the present invention is above 12,000 GS, the coverage radius of the magnetic field lines in the horizontal direction is about 50 cm, and the coverage height of the magnetic field lines directly above is about 50 cm. Correspondingly, the magnetic field range of the rotating magnetic field is wider and the intensity is higher, and the magnetic force decay is slower, which can more effectively promote local blood circulation in the human body, relieve muscle tension and reduce pain.
[0019] 3. After the fixing block is connected to the connecting shaft of the brushless motor, due to the friction force between the fixing block and the strong magnetic assembly, the brushless motor can stably drive the strong magnetic assembly to rotate.
[0020] 4. The fixed magnet in the installation notch generates an upward repulsive force on the floating magnet fixed to the lower end of the rotating shaft. Correspondingly, the floating magnet and the motor rotor fixed to the floating magnet are both limited to the specified positions, so that the motor rotor does not vibrate during rotation, reducing mechanical vibration noise.
[0021] 5. The fixed magnet generates an upward repulsive force on the floating magnet. At the same time, the motor rotor fixed to the floating magnet also receives an upward acting force, reducing the friction between the stepped portion and the top of the radial ball bearing during the rotation of the motor rotor, and reducing mechanical friction noise.
[0022] 6. An upper support portion is formed on the outer cover of the present invention, and a lower support portion adapted to the upper support portion is formed on the base. Bolts or studs pass through the upper support portion and the lower support portion to facilitate fixing the rotating magnetic mechanism in furniture such as mattresses or sofas, which is beneficial to the stable operation of the rotating magnetic mechanism.
[0023] 7. The present invention can control the rotation speed of the brushless motor by controlling the current of the brushless motor, and then control the decibels during the operation of the brushless motor. At the same time, the surface magnetic induction intensity does not change significantly, and the stability is good.
[0024] 8. The limiting block and the rotating shaft of the present invention perform upper limiting on the radial spherical bearing, and the end cover and the upper floating magnet perform lower limiting on the radial spherical bearing, so that the radial spherical bearing does not move up and down and can be fixed in a specified position to promote the stable rotation of the motor rotor.
[0025] 9. The volumes of the A-magnet block and the C-magnet block group, and the B-magnet block and the D-magnet block group of the present invention each occupy half of the main body of the strong magnetic component, and the A-magnet block and the B-magnet block are magnet blocks with the same volume.

Detailed Embodiments
[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Embodiment 1: As Figures 1 - 3 shown, a strong magnetic component includes a strong magnetic component body 2. The strong magnetic component body 2 includes an A magnetic block 21, a C magnetic block group 23, a B magnetic block 22, and a D magnetic block group 24 arranged circumferentially in a clockwise direction. The A magnetic block 21 and the C magnetic block group 23 have the same magnetic poles, the B magnetic block 22 and the D magnetic block group 24 have the same magnetic poles, the magnetic poles of the A magnetic block 21 and the B magnetic block 22 are opposite, and the C magnetic block group 23 and the D magnetic block group 24 are each composed of a plurality of axially arranged magnetic blocks spliced together.
[0029] Among them, the strong magnetic component body 2 is a cylinder with a cavity inside. The N and S poles in the strong magnetic component body 2 are as Figures 2 - 3 shown. The A magnetic block 21, the B magnetic block 22, the C magnetic block group 23, and the D magnetic block group 24 are magnetically connected to each other, and the magnetic blocks forming the C magnetic block group 23 and the D magnetic block group 24 are also magnetically connected to each other. The C magnetic block group 23 and the D magnetic block group 24 are composed of magnetic blocks with the same number and the same magnetic force.
[0030] The volume of the A magnetic block 21 and the C magnetic block group 23 is 1 / 2 of the strong magnetic component body 2, the volume of the B magnetic block 22 and the D magnetic block group 24 is 1 / 2 of the strong magnetic component body 2, and the volume of the A magnetic block 21 is equal to the volume of the B magnetic block 22.
[0031] The volume of the A magnetic block 21 is 2 - 5 times the volume of the C magnetic block group 23.
[0032] Specifically, the volumes of the A magnetic block 21 and the C magnetic block group 23, and the B magnetic block 22 and the D magnetic block group 24 each account for half of the strong magnetic component body 2, and the A magnetic block 21 and the B magnetic block 22 are both magnetic blocks with the same volume. Furthermore, the magnetic force lines in the strong magnetic component body 2 can be evenly distributed, ensuring the stability of the magnetic field of the strong magnetic component body 2 and improving the magnetic therapy effect of the strong magnetic component. Moreover, the volumes of the A magnetic block 21 and the B magnetic block 22 are both larger than those of the C magnetic block group 23 and the D magnetic block group 24. The volumes of the A magnetic block 21 and the B magnetic block 22 are preferably 4 times those of the C magnetic block group 23 and the D magnetic block group 24. The A magnetic block 21 and the B magnetic block 22 generate a large number of magnetic force lines distributed around the strong magnetic component. The magnetic force lines generated by the C magnetic block group 23 and the D magnetic block group 24 composed of upper and lower magnetic blocks spliced together are higher. On the basis of combining the C magnetic block group 23 and the D magnetic block group 24, the A magnetic block 21 and the B magnetic block 22 enable the magnetic force lines to be emitted upward at an angle. The magnetic force lines are as Figure 3 shown, improving the penetration height of the magnetic field; Magnetic block A 21, magnetic block B 22, magnetic block group C 23 and magnetic block group D 24. The above four magnetic blocks are spliced to form the strong magnetic component body 2. Compared with a single fixed magnetic block, this kind of composite magnetic block such as the strong magnetic component body 2 has a greater magnetic surface strength, a wider magnetic field line coverage area, a slower decline of magnetic force, and a better magnetic therapy effect.
[0033] In a specific embodiment, for the strong magnetic component body 2 composed of magnetic block A 21, magnetic block B 22, magnetic block group C 23 and magnetic block group D 24, the surface magnetic induction intensity is above 12000 GS (Gauss), the height of magnetic field penetration is about 50 cm, and the radius of magnetic field penetration is about 50 cm. When the magnetic field penetration height H = 40 cm, the magnetic induction intensity B > 1 GS; when the magnetic field penetration diameter Φ = 100 cm, the magnetic induction intensity B = 1 GS.
[0034] The strong magnetic component body 2 includes a stainless steel outer cover 25 and a magnetic isolation sheet 26. The stainless steel outer cover 25 is used to wrap magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24 into one body. The magnetic isolation sheet 26 is located at the bottom of magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24.
[0035] Specifically, the stainless steel outer cover 25 is in clearance fit with magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24. The stainless steel outer cover 25 wraps magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24 into one body, avoiding the separation of the strong magnetic component due to centrifugal force during high-speed rotation, thereby affecting the magnetic field effect. On the one hand, the magnetic isolation sheet 26 makes the magnetic field lines emit upward, increasing the surface magnetic strength of the strong magnetic component. On the other hand, it avoids the downward penetration of the magnetic field lines of magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24, affecting the operation of the brushless motor 1 connected to the magnetic isolation sheet 26.
[0036] The present invention adopts the horizontal splicing between magnetic block A 21, magnetic block B 22, magnetic block group C 23, and magnetic block group D 24, so that the surface magnetic induction intensity of the strong magnetic component is above 12000 GS, and the coverage radius of the magnetic field lines in the horizontal direction is about 50 cm. The magnetic block groups C 23 and D 24 formed by splicing several magnetic blocks up and down make the coverage height of the magnetic field lines directly above about 50 cm. With the operation of the brushless motor 1, a rotating magnetic field with a wider range and higher intensity can be generated, which can perform continuous large-area magnetic therapy on a specified part of the human body, and the magnetic therapy effect is better. Furthermore, the rotating magnetic field with a wider range and higher intensity decays more slowly, can more effectively promote local blood circulation in the human body, relieve muscle tension, and reduce pain.
[0037] In the middle position of the main body 2 of the strong magnetic component, an upper cavity 27 and a lower cavity 28 are formed. The upper cavity 27 is located above the lower cavity 28. The diameter of the upper cavity 27 is larger than that of the lower cavity 28. A fixing block 29 is accommodated inside the upper cavity 27.
[0038] As Figures 1 - 6 shown, a gyromagnetic mechanism includes a strong magnetic component, a brushless motor 1 and a housing 3. The brushless motor 1 is arranged directly below the strong magnetic component and controls the rotation or stillness of the strong magnetic component. The rotating strong magnetic component can generate a rotating magnetic field to perform magnetic therapy on the human body. The housing 3 includes a base 31 and an outer cover 32. The base 31 is used to support the brushless motor 1 and the strong magnetic component. The outer cover 32 is used to cover the brushless motor 1 and the strong magnetic component to protect the brushless motor 1 and the strong magnetic component. On one side of the base 31 facing the brushless motor 1, there is an upwardly protruding support column 311. A cavity is formed inside the support column 311, and a notch 3111 is formed at the bottom of the support column 311.
[0039] Among them, both the base 31 and the outer cover 32 are processed from reinforced PBT material. The PBT material is an engineering plastic, and the engineering plastic material has good insulation and corrosion resistance.
[0040] An upper support portion 321 is formed on the outer cover 32, and a lower support portion 312 adapted to the upper support portion 321 is formed on the base 31. Bolts or studs pass through the upper support portion 321 and the lower support portion 312 to conveniently fix the gyromagnetic mechanism in furniture such as mattresses or sofas, which is beneficial to the stable operation of the gyromagnetic mechanism.
[0041] The brushless motor 1 includes a motor stator 11 and a motor rotor 12. The motor rotor 12 is arranged outside the motor stator 11 and can rotate around the motor stator 11. In the middle position of the motor rotor 12, there is an upwardly protruding connecting shaft 121 and a downwardly protruding rotating shaft 122. The connecting shaft 121 is accommodated in the lower cavity 28 of the strong magnetic component, and the rotating shaft 122 is accommodated in the cavity of the support column 311.
[0042] It should be noted that after the connecting shaft 121 is connected and matched with the lower cavity 28, its top is still lower than the top of the lower cavity 28. Correspondingly, when a bolt passes through the fixing block 29 to connect the fixing block 29 and the connecting shaft 121, the fixing block 29 abuts against the surface of the strong magnetic component facing the fixing block 29. Furthermore, while the fixing block 29 rotates with the connecting shaft 121, the frictional force between the fixing block 29 and the strong magnetic component causes the strong magnetic component to rotate synchronously. Correspondingly, the rotation of the motor rotor 12 in the brushless motor 1 drives the strong magnetic component to rotate.
[0043] The brushless motor 1 includes a radial ball bearing 13, an upper suspension magnet 14, a lower suspension magnet 15, an end cover 16 and a limit block 17. The end cover 16 includes a mounting portion 161, a positioning portion 162 and a mounting notch 163. The mounting portion 161 is received in the notch 3111 of the support column 311. The suspension magnet 14 is fixedly arranged at the lower end of the rotating shaft 122. The fixed magnet 15 is received in the mounting notch 163. The fixed magnet 15 generates a magnetic force to limit the suspension magnet 14 at a specified position. The rotating shaft 122 includes a rotating portion 1221 and a stepped portion 1222. The radial ball bearing 13 is located between the support column 311 and the rotating shaft 122. One end of the top of the radial ball bearing 13 abuts against the limit block 17 fixed to the upper end of the support column 311. The other end of the top of the radial ball bearing 13 is abutted by the stepped portion 1222. One end of the bottom of the radial ball bearing 13 abuts against the suspension magnet 14 fixed to the lower end of the rotating shaft 122. The other end of the bottom of the radial ball bearing 13 is abutted by the positioning portion 161. At the same time, the limit block 17 located on the support column 311 also abuts against the motor stator 11.
[0044] Specifically, the limit block 17 and the rotating shaft 122 perform upper limit on the radial ball bearing 13, and the end cover 16 and the suspension magnet 14 perform lower limit on the radial ball bearing 13, so that the radial ball bearing 13 does not move up and down, and is fixed at a specified position to promote the stable rotation of the motor rotor 12. The fixed magnet 15 located in the mounting notch 163 generates an upward repulsive force on the suspension magnet 14 fixed to the lower end of the rotating shaft 122. Correspondingly, both the suspension magnet 14 and the motor rotor 12 fixed to the suspension magnet 14 are limited at a specified position, so that the motor rotor 12 does not vibrate during rotation, reducing mechanical vibration noise. At the same time, the motor rotor 12 fixed to the suspension magnet 14 also receives an upward acting force, reducing the friction between the stepped portion 1222 and the top of the radial ball bearing 13 during the rotation of the motor rotor 12, reducing mechanical friction noise. Finally, the decibel of the brushless motor 1 during operation is reduced.
[0045] The brushless motor 1 includes a control chip 18. The control chip 18 is coated inside the housing 3 and is arranged away from the motor rotor 12. The control chip 18 can adjust the phase and amplitude of the current of the brushless motor 1, and further control the speed and torque of the brushless motor to ensure the stable operation of the rotating magnetic field.
[0046] The brushless motor 1 of the present invention is preferably a DC brushless motor, with a required voltage of 12V, a rated current of 0.04A, a power between 1 - 3W, and can control the rotation speed of the strong magnetic component between 300 revolutions per minute and 600 revolutions per minute. After multiple groups of data are stably tested, Table 1 is obtained: Table 1: Performance Test Table of the Rotary Magnetic Mechanism Group Current / Power (A / W) Rotational Speed (rad / min) Noise at 10 cm Distance (dB) Noise at 30 cm Distance (dB) Surface Magnetic Intensity (GS) Penetration Height Directly Above (cm) Magnetic Field Range Radius (cm) 1 0.048 / 2.8 573 39.4 32.3 12800 50 60 2 0.047 / 2.6 578 35 30.8 12540 50 55 3 0.039 / 1.4 317 32.9 25.6 12800 50 60 4 0.039 / 1.3 329 30.3 24.7 12540 50 55 In Table 1, it can be clearly seen that when the current decreases, the noise will also decrease accordingly. During the operation of the rotary magnetic mechanism, the noise is below 40 decibels, the surface magnetic intensity is greater than 12,000 GS, the height of the magnetic field penetrating upward is about 50 cm, and the radius of the magnetic field penetration is more than 50 cm.
[0047] In the present invention, the brushless motor 1 and the strong magnetic component cooperate to form a rotating magnetic field. The magnetic force range of this rotating magnetic field is relatively wide, the magnetic force intensity is between 600 gauss and 1500 gauss, the magnetic force attenuation is slow, and it can perform continuous large-area magnetic therapy on the specified part of the human body, with better magnetic therapy effect.
[0048] By setting the suspension magnet 14 and the fixed magnet 15, the present invention reduces mechanical contact and vibration, reduces mechanical noise. At the same time, due to the reduction of mechanical friction and vibration, the service life of the brushless motor 1 is improved.
[0049] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the number of magnetic blocks in the C magnetic block group 23 and the D magnetic block group 24 is different.
[0050] The C magnetic block group 23 and the D magnetic block group 24 have the same volume. However, the C magnetic block group 23 can be composed of 3 smaller magnetic blocks spliced together, and the D magnetic block group 24 can be composed of 2 larger magnetic blocks spliced together. But the magnetic fields generated by both are the same, which does not affect the magnetic therapy effect of the rotary magnetic mechanism.
