Description

Technical Field

[0002] Fitness equipment such as magnetic resistance spinning bikes, elliptical trainers, and rowing machines for aerobic exercise projects are becoming increasingly popular in the market. They generally include a frame body, an internal magnetic control device, a flywheel, and a pedaling device, which are respectively installed on the frame body. The flywheel surrounds the outside of the internal magnetic control device and is drivably connected to the pedaling device. When a user drives the flywheel to rotate relative to the frame body and the internal magnetic control device through the pedaling device, the flywheel can cut the magnetic induction lines of the magnetic group of the internal magnetic control device to obtain resistance, thereby assisting the user in fitness. By adjusting the relative position between the magnetic group of the internal magnetic control device and the flywheel, the resistance of the flywheel when it is driven to rotate can be adjusted, so as to help the user achieve different fitness effects. How to easily and reliably drive the magnetic group of the internal magnetic control device to move relative to the flywheel to adjust the relative position between the magnetic group of the internal magnetic control device and the flywheel is a technical problem that the inventors of the present invention are committed to solving.

[0070] Attached Figure 1 shows a fitness equipment according to a preferred embodiment of the present invention. Attached Figures 2 to 8B shows an inner magnetic control device 100 according to a preferred embodiment of the present invention, and the inner magnetic control device 100 is used to provide a magnetic field environment, wherein the fitness equipment applies the inner magnetic control device 100 of the present invention. Attached Figures 9A to 9E shows the assembly process of the inner magnetic control device 100.

[0071] It is worth mentioning that Figure 1 The fitness equipment shown as an elliptical machine is only exemplary and does not limit the specific type of the fitness equipment of the present invention. For example, in other examples of the present invention, the fitness equipment can also be a rowing machine, a spinning bike, etc.

[0072] Reference Attachment Figure 1 and Figure 2 The fitness equipment of the present invention includes the internal magnetic control device 100, an equipment frame 200, a pedaling device 300, and a flywheel 400. The internal magnetic control device 100 is mounted on the equipment frame 200, the pedaling device 300 is pedalably mounted on the equipment frame 200, the flywheel 400 is rotatably mounted on the equipment frame 200 and drivably connected to the pedaling device 300, and the flywheel 400 is disposed around the outer side of the internal magnetic control device 100. When a user continuously pedals the pedaling device 300, driving the flywheel 400 to rotate relative to the internal magnetic control device 100 and the equipment frame 200, the flywheel 400 continuously cuts the magnetic flux lines of the internal magnetic control device 100 and generates a load, thereby enabling the user to achieve fitness through the fitness equipment.

[0073] It is understood that the load obtained by the flywheel 400 when driven to rotate is related to the amount of magnetic flux lines of the internal magnetic control device 100 that the flywheel 400 cuts. Specifically, the more the flywheel 400 cuts the magnetic flux lines of the internal magnetic control device 100 when driven to rotate, the greater the load the flywheel 400 can obtain, and the more effort the user will exert when stepping on the pedaling device 300. Correspondingly, the less the flywheel 400 cuts the magnetic flux lines of the internal magnetic control device 100 when driven to rotate, the smaller the load the flywheel 400 can obtain, and the less effort the user will exert when stepping on the pedaling device 300.

[0074] It is worth mentioning that the load obtained by the flywheel 400 when being driven to rotate is reflected in the resistance value when the user steps on the pedaling device 300. The greater the load obtained by the flywheel 400 when being driven to rotate, the greater the resistance value when the user steps on the pedaling device 300. Correspondingly, the smaller the load obtained by the flywheel 400 when being driven to rotate, the smaller the resistance value when the user steps on the pedaling device 300.

[0075] In order to meet the different requirements of users for the load of the flywheel 400 of the fitness equipment, the internal magnetic control device 100 of the present invention is arranged to be able to adjust the relative position of the magnetic induction lines and the flywheel 400. Thus, when the position of the magnetic induction lines of the internal magnetic control device 100 is closer to the flywheel 400, the amount of magnetic induction lines of the internal magnetic control device 100 cut by the flywheel 400 when the flywheel 400 is driven to rotate is more. Correspondingly, when the position of the magnetic induction lines of the internal magnetic control device 100 is farther from the flywheel 400, the amount of magnetic induction lines of the internal magnetic control device 100 cut by the flywheel 400 when the flywheel 400 is driven to rotate is less. Therefore, by adjusting the relative position of the magnetic induction lines of the internal magnetic control device 100 and the flywheel 400, the resistance value when the user steps on the stepping device 300 can be adjusted.

[0076] Specifically, referring to the attached Figures 2 to 8B , the internal magnetic control device 100 includes a magnetic control housing 10, a driving module 20, two swing arms 30, and two groups of magnetic elements 40. The magnetic control housing 10 has a housing space 101 and a peripheral opening 102 communicating with the housing space 101. The driving module 20 is arranged in the housing space 101 of the magnetic control housing 10 to provide driving force. Each swing arm 30 has a pivot end 31 and a driven end 32 corresponding to the pivot end 31. The pivot end 31 of the swing arm 30 is rotatably mounted on the magnetic control housing 10, and the driven end 32 of the swing arm 30 is drivingly connected to the driving module 20. The two swing arms 30 are held in the peripheral opening 102 of the magnetic control housing 10 in a symmetric manner. Each group of magnetic elements 40 is respectively arranged on each swing arm 30 to allow each group of magnetic elements 40 to provide a magnetic field environment at the peripheral opening 102 of the magnetic control housing 10. The flywheel 400 can surround the outside of the magnetic control housing 10 of the internal magnetic control device 100, and the peripheral opening 102 of the magnetic control housing 10 corresponds to the inside of the flywheel 400. Thus, when the flywheel 400 is driven to rotate relative to the internal magnetic control device 100, the flywheel 400 can cut the magnetic induction lines of each group of magnetic elements 40 of the internal magnetic control device 100 to obtain a load.

[0077] Preferably, the outer side of each swing arm 30 faces the peripheral opening 102 of the magnetic control housing 10, and each group of magnetic elements 40 is respectively arranged on the outer side of each swing arm 30, so that each group of magnetic elements 40 can be directly exposed to the peripheral opening 102 of the magnetic control housing 10.

[0078] It is worth mentioning that the way each group of the magnetic elements 40 is arranged on each of the swing arms 30 is not limited in the internal magnetic control device 100 of the present invention. For example, in a preferred example of the internal magnetic control device 100 of the present invention, each group of the magnetic elements 40 can be arranged on each of the swing arms 30 by means of glue bonding; in another preferred example of the internal magnetic control device 100 of the present invention, each group of the magnetic elements 40 can be arranged on each of the swing arms 30 by means of embedding.

[0079] It is worth mentioning that the number of the magnetic elements 40 in each group of the magnetic elements 40 is not limited in the internal magnetic control device 100 of the present invention. For example, in this specific example of the internal magnetic control device 100 shown in the attached Figures 2 to 8B drawing, the number of the magnetic elements 40 in each group of the magnetic elements 40 is three, and they are arranged on the outer side of the swing arm 30 at intervals.

[0080] Preferably, the swing arm 30 extends curvedly between the pivot end 31 and the driven end 32 so that the swing arm 30 is in an arc shape, so that the shape of the outer side of the swing arm 30 is substantially the same as the shape of the periphery of the magnetic control housing 10. Preferably, a group of the magnetic elements 40 is in an arc shape, and the shape of the inner side of a group of the magnetic elements 40 is consistent with the shape of the outer side of the swing arm 30, so as to facilitate the reliable arrangement of a group of the magnetic elements 40 on the outer side of the swing arm 30.

[0081] Referring to the attached Figures 3A to 4B drawing, the magnetic control housing 10 includes a disc-shaped first housing 11 and a disc-shaped second housing 12. The first housing 11 is provided with a first ring body 111, and the second housing 12 is provided with a second ring body 121. The first housing 11 and the second housing 12 are installed with each other in such a way that the first ring body 111 and the second ring body 121 correspond to each other, so as to form the housing space 101 inside the first ring body 111 and the second ring body 121, and to form the peripheral opening 102 outside the first ring body 111 and the second ring body 121.

[0082] Furthermore, a plurality of first mounting posts 112 are provided at the edge of the first housing 11, and a plurality of second mounting posts 122 are provided at the edge of the second housing 12. Each of the first mounting posts 112 of the first housing 11 and each of the second mounting posts 122 of the second housing 12 are installed and supported with each other to prevent the edges of the first housing 11 and the second housing 12 from being deformed. Preferably, screws are allowed to lock the first housing 11 and the second housing 12 at the positions of the first mounting posts 112 of the first housing 11 and the second mounting posts 122 of the second housing 12.

[0083] On opposite sides of the pivot end 31 of the swing arm 30, it is rotatably mounted on the edge of the first housing 11 and the edge of the second housing 12, so as to rotatably mount the pivot end 31 of the swing arm 30 on the edge of the magnet control housing 10, and the swing arm 30 is allowed to swing at the peripheral opening 102 of the magnet control housing 10. Each first mounting post 112 of the first housing 11 and each second mounting post 122 of the second housing 12 are located outside the swing arm 30 to limit the amplitude of the outward swing of the swing arm 30. Preferably, the first mounting post 112 of the first housing 11 and the second mounting post 122 of the second housing 12 correspond to the gaps between two adjacent magnetic elements 40 in a group of the magnetic elements 40 to avoid the magnetic elements 40.

[0084] Reference appendix Figures 3A to 4B The magnet control housing 10 further has a central perforation 103, and the housing space 101 is located around the central perforation 103, wherein the mounting shaft of the equipment rack 200 can be mounted in the central perforation 103 of the magnet control housing 10 to fixedly mount the inner magnet control device 100 on the equipment rack 200.

[0085] When the user drives the flywheel 400 to rotate relative to the inner magnet control device 100 by stepping on the stepping device 300 of the fitness equipment, the flywheel 400 can cut the magnetic induction lines of each group of the magnetic elements 40 of the inner magnet control device 100 to obtain a load, so that the user can achieve the purpose of fitness through the fitness equipment.

[0086] When the driving module 20 drives each swing arm 30 to swing relative to the magnet control housing 10 respectively, each group of swing arms 30 can drive each group of magnetic elements 40 to swing synchronously to change the relative distance between each group of magnetic elements 40 and the flywheel 400. In this way, the relative distance between the magnetic induction lines of the inner magnet control device 100 and the flywheel 400 is adjusted, so as to adjust the load obtained by the flywheel 400 when it is driven to rotate, and further the resistance value when the user steps on the stepping device 300 can be adjusted.

[0087] For example, reference appendix Figure 8A When the driving module 20 drives each swing arm 30 to swing outward to a maximum swing position, the relative distance between each group of magnetic elements 40 and the flywheel 400 is adjusted to the designed minimum value. At this time, the amount of magnetic induction lines cut by the flywheel 400 when it is driven to rotate for each group of magnetic elements 40 is the largest, and the resistance that the flywheel 400 can obtain is the largest. Correspondingly, reference appendix Figure 8B, when the driving module 20 drives each swing arm 30 to swing inward to a minimum swing position, the relative distance between each group of magnetic elements 40 and the flywheel 400 is adjusted to the designed maximum value. At this time, when the flywheel 400 is driven to rotate, the amount of magnetic induction lines of each group of magnetic elements 40 cut by the flywheel 400 is the least, and the resistance that the flywheel 400 can obtain is the smallest.

[0088] It can be understood that during the process in which the driving module 20 drives each swing arm 30 to swing from the minimum swing position to the maximum swing position respectively, the amount of magnetic induction lines of each group of magnetic elements 40 cut by the flywheel 400 when the flywheel 400 is driven to rotate gradually increases, so that the resistance that the flywheel 400 can obtain when being driven to rotate gradually increases. Correspondingly, during the process in which the driving module 20 drives each swing arm 30 to swing from the maximum swing position to the minimum swing position respectively, the amount of magnetic induction lines of each group of magnetic elements 40 cut by the flywheel 400 when the flywheel 400 is driven to rotate gradually decreases, so that the resistance that the flywheel 400 can obtain when being driven to rotate gradually decreases.

[0089] Reference appendix Figures 4A to 8B , the driving module 20 includes a driving mechanism 21 and two linkage mechanisms 22. One end of each linkage mechanism 22 is respectively drivably connected to the driving mechanism 21, and the other end of each linkage mechanism 22 is respectively rotatably mounted on the driven end 32 of each swing arm 30. Among them, the two linkage mechanisms 22 have an overlapping part in the height direction. In this way, when the driving force provided by the driving mechanism 21 is transmitted to each linkage mechanism 22, each linkage mechanism 22 can apply a force to each swing arm 30 at a larger angle to drive each swing arm 30 to drive each group of magnetic elements 40 to swing relative to the magnetic control housing 10 respectively. Thus: on the one hand, the internal magnetic control device 100 of the present invention can reduce the requirement for the driving force of the driving mechanism 21, which is beneficial to reducing the cost of the internal magnetic control device 100; on the other hand, the internal magnetic control device 100 of the present invention can smoothly drive each swing arm 30 to swing within a larger range, which is beneficial to improving the reliability of the internal magnetic control device 100.

[0090] It is worth mentioning that the manner in which the linkage mechanism 22 is rotatably mounted on the driven end 32 of the swing arm 30 is not limited in the internal magnetic control device 100 of the present invention. For example, the internal magnetic control device 100 further includes two assemblies 50, wherein the end of the linkage mechanism 22 is rotatably mounted on the assembly 50, and the assembly 50 is mounted on the driven end 32 of the swing arm 30, so as to rotatably mount the end of the linkage mechanism 22 on the driven end 32 of the swing arm 30 in this way.

[0091] For the sake of easy understanding and description, with reference to the attached Figure 8A and Figure 8B , two of the swing arms 30 of the internal magnet control device 100 are defined as a left swing arm 30a and a right swing arm 30b. Correspondingly, two of the linkage mechanisms 22 of the drive module 20 of the internal magnet control device 100 are defined as a left linkage mechanism 22a and a right linkage mechanism 22b. One end of the left linkage mechanism 22a is rotatably mounted on the driven end 32 of the left swing arm 30a, and the other end of the left linkage mechanism 22a extends towards the right swing arm 30b and is drivingly connected to the drive mechanism 21. Correspondingly, one end of the right linkage mechanism 22b is rotatably mounted on the driven end 32 of the right swing arm 30b, and the other end of the right linkage mechanism 22b extends towards the left swing arm 30a and is drivingly connected to the drive mechanism 21, wherein the left linkage mechanism 22a and the right linkage mechanism 22b have an overlapping part in the height direction. For example, in this specific example of the internal magnet control device 100 shown in the attached Figures 2 to 8B , the right linkage mechanism 22b is located above the left linkage mechanism 22a. Of course, it can be understood that in other alternative examples of the internal magnet control device 100 of the present invention, the right linkage mechanism 22b may be located below the left linkage mechanism 22a.

[0092] In other words, the projection of the left linkage mechanism 22a on the magnet control housing 10 and the projection of the right linkage mechanism 22b on the magnet control housing 10 have an overlapping part and are in an "X" shape. In this way, the included angle formed by the extension direction of the line connecting the centers of the pivot end 31 and the driven end 32 of the left swing arm 30a and the extension direction of the left linkage mechanism 22a is relatively large, so as to allow the left linkage mechanism 22a to apply force to the left swing arm 30a at a relatively large angle. Correspondingly, the included angle formed by the extension direction of the line connecting the centers of the pivot end 31 and the driven end 32 of the right swing arm 30b and the extension direction of the right linkage mechanism 22b is relatively large, so as to allow the right linkage mechanism 22b to apply force to the right swing arm 30b at a relatively large angle.

[0093] When the driving mechanism 21 outputs power in one direction, the driving mechanism 21 can drive the left linkage mechanism 22a to move towards the direction close to the right swing arm 30b, so as to allow the left linkage mechanism 22a to easily pull the driven end 32 of the left swing arm 30a at a large angle to swing the left swing arm 30a inwards. At the same time, the driving mechanism 21 can drive the right linkage mechanism 22b to move towards the direction close to the left swing arm 30a, so as to allow the right linkage mechanism 22b to easily pull the driven end 32 of the right swing arm 30b at a large angle to swing the right swing arm 30b inwards. Correspondingly, when the driving mechanism 21 outputs power in the reverse direction, the driving mechanism 21 can drive the left linkage mechanism 22a to move away from the right swing arm 30b, so as to allow the left linkage mechanism 22a to easily push the driven end 32 of the left swing arm 30a at a large angle to swing the left swing arm 30a outwards. At the same time, the driving mechanism 21 can drive the right linkage mechanism 22b to move away from the left swing arm 30a, so as to allow the right linkage mechanism 22b to easily pull the driven end 32 of the right swing arm 30b at a large angle to swing the right swing arm 30b outwards.

[0094] Preferably, through this structural design of the internal magnetic control device 100 of the present invention, whether it is during the process that the left linkage mechanism 22a pulls the left swing arm 30a from the maximum swing position to the minimum swing position, or during the process that the left linkage mechanism 22a pushes the left swing arm 30a from the minimum swing position to the maximum swing position, the left linkage mechanism 22a can maintain applying force to the left swing arm 30a at a large angle; correspondingly, whether it is during the process that the right linkage mechanism 22b pulls the right swing arm 30b from the maximum swing position to the minimum swing position, or during the process that the right linkage mechanism 22b pushes the right swing arm 30b from the minimum swing position to the maximum swing position, the right linkage mechanism 22b can maintain applying force to the right swing arm 30b at a large angle.

[0095] Continue to refer to the appendix Figures 5A to 7, the driving module 20 includes a driving housing 23, the driving housing 23 has a housing space 231 and a side opening 232 communicating with the housing space 231, wherein the driving mechanism 21 is disposed in the housing space 231 of the driving housing 23, and one end of each linkage mechanism 22 is respectively and drivably connected to the driving mechanism 21 in the housing space 231 of the driving housing 23, and the other end of each linkage mechanism 22 extends to the outside of the driving housing 23 through the side opening 232 of the driving housing 23, so as to be rotatably mounted on the driven end 32 of each swing arm 30 through the assembly 50. In this way, the driving module 20 can form an independent module.

[0096] In other words, in the internal magnetic control device 100 of the present invention, the driving module 20 can be installed as an independent module in the housing space 101 of the magnetic control housing 10. In this way, the same driving module 20 can be adapted to different magnetic control housings 10. For example, the same driving module 20 can be adapted to magnetic control housings 10 of different sizes to obtain corresponding specifications of the internal magnetic control device 100 to meet the use requirements of different fitness equipment.

[0097] Preferably, the magnetic control housing 10 has an installation channel 104 communicating with the housing space 101 of the magnetic control housing 10, and the driving module 20 is allowed to be installed in the housing space 101 of the magnetic control housing 10 through the installation channel 104 of the magnetic control housing 10. Preferably, the installation channel 104 of the magnetic control housing 10 is formed in the first housing 11. In other words, in the internal magnetic control device 100 of the present invention, by providing the independent driving module 20, when assembling the internal magnetic control device 100, the first housing 11 and the second housing 12 can be installed first to obtain the magnetic control housing 10, and then the driving module 20 can be installed in the housing space 101 of the magnetic control housing 10. In this way: on the one hand, the assembly difficulty of the internal magnetic control device 100 can be greatly reduced; on the other hand, without disassembling the magnetic control housing 10, the resistance calibration of the internal magnetic control device 100 can be completed only by disassembling the driving module 20 and calibrating it, thereby greatly improving the production efficiency and calibration efficiency of the internal magnetic control device 100.

[0098] Specifically, the driving housing 23 includes a first housing 233 and a second housing 234, and the first housing 233 and the second housing 234 are installed with each other to form the housing space 231 and the side opening 232 between the first housing 233 and the second housing 234.

[0099] It is worth mentioning that the mutual installation manner of the first housing 233 and the second housing 234 is not limited in the internal magnetron device 100 of the present invention. For example, the first housing 233 and the second housing 234 can be mutually installed by screws, or the first housing 233 and the second housing 234 can be mutually installed by a combination of a screw rod and a nut, or the first housing 233 and the second housing 234 can be installed in a mutually snap-fitting manner.

[0100] Continue to refer to the attached Figures 5A to 7 As shown, the driving mechanism 21 further includes a driving motor 211 and a gear set 212. The driving motor 211 is fixedly installed in the housing space 231 of the driving housing 23. For example, the driving motor 211 can be fixedly installed in the housing space 231 of the driving housing 23 by allowing the first housing 233 and the second housing 234 to clamp the driving motor 211 on opposite sides of the driving motor 211. The gear set 212 includes a driven gear 2121, at least one transmission gear 2122, and two power output gears 2123. The driven gear 2121, the transmission gear 2122, and each power output gear 2123 are respectively rotatably installed in the housing space 231 of the driving housing 23. For example, opposite sides of the driven gear 2121, opposite sides of the transmission gear 2122, and opposite sides of each power output gear 2123 are respectively rotatably installed on the first housing 233 and the second housing 234 to rotatably install the driven gear 2121, the transmission gear 2122, and each power output gear 2123 in the housing space 231 of the driving housing 23, wherein the driven gear 2121 is meshed with the output shaft 2111 of the driving motor 211, the transmission gear 2122 is meshed with the driven gear 2121, the two power output gears 2123 are meshed with each other, and one of the two power output gears 2123 is meshed with the transmission gear 2122.

[0101] Each linkage mechanism 22 respectively has a row of driven teeth 221, wherein the driven teeth 221 of each linkage mechanism 22 are respectively meshed with each power output gear 2123 of the gear set 212. Thus, when the driving motor 211 outputs power in a manner that the output shaft 2111 of the driving motor 211 rotates, the power can be transmitted to each linkage mechanism 22 in sequence through the driven gear 2121, the transmission gear 2122, and each power output gear 2123 to drive each linkage mechanism 22 to move and further drive each swing arm 30 to swing.

[0102] Specifically, referring to the attached Figure 8A and Figure 8B , a row of the driven teeth 221 are respectively provided on the side parts of the left linkage mechanism 22a and the right linkage mechanism 22b, wherein the driven teeth 221 of the left linkage mechanism 22a are engaged with one of the power output gears 2123, and the driven teeth 221 of the right linkage mechanism 22b are engaged with the other power output gear 2123. When the drive motor 211 outputs power in a manner that the output shaft 2111 of the drive motor 211 rotates, the power can be sequentially transmitted to each of the power output gears 2123 through the driven gear 2121 and the transmission gear 2122, so as to drive each of the power output gears 2123 to rotate synchronously and reversely. At this time, one of the power output gears 2123 and the left linkage mechanism 22a can cooperate with each other to drive the left swing arm 30a to swing, and the other power output gear 2123 and the right linkage mechanism 22b can cooperate with each other to drive the right swing arm 30b to swing, and the swing direction and swing amplitude of the left swing arm 30a are the same as those of the right swing arm 30b.

[0103] Preferably, a gap is provided between the two linkage mechanisms 22 to avoid friction between the two linkage mechanisms 22. In this way: on the one hand, the drive mechanism 21 can smoothly drive each swing arm 30 to swing through each linkage mechanism 22; on the other hand, the two linkage mechanisms 22 will not generate friction, thereby avoiding the generation of noise and wear of the linkage mechanisms 22.

[0104] Continuing to refer to the attached Figures 5A to 7 , each of the linkage mechanisms 22 respectively includes a slider 222 and a connecting rod 223. One end of the connecting rod 223 is rotatably installed on the slider 222, and the other end of the connecting rod 223 is rotatably installed on the driven end 32 of the swing arm 30, wherein the slider 222 is drivably installed on the drive mechanism 21, so that the flexibility of the drive module 20 to drive the swing arm 30 to swing can be improved, avoiding the occurrence of the bad phenomenon of "jamming", and thus ensuring the reliability of the internal magnetron device 100.

[0105] Preferably, the driven teeth 221 of the linkage mechanism 22 are formed on the side wall of the slider 222 to allow the slider 222 to be drivably connected to the power output gear 2123 of the gear set 212.

[0106] Continuing to refer to the attached Figures 5A to 7, the drive housing 23 further includes two tracks 235 which respectively form the inner walls of the first housing 233 and the second housing 234. Correspondingly, each slider 222 of each linkage mechanism 22 has a sliding groove 2221. The track 235 formed in the first housing 233 can extend into the sliding groove 2221 of the slider 222 of one of the linkage mechanisms 22 to allow the slider 222 of this linkage mechanism 22 to be slidably seated on the track 235 formed in the first housing 233. Correspondingly, the track 235 formed in the second housing 234 can extend into the sliding groove 2221 of the slider 222 of the other linkage mechanism 22 to allow the slider 222 of this linkage mechanism 22 to be slidably seated on the track 235 formed in the second housing 234.

[0107] In other words, the track 235 of the drive housing 23 can guide the movement direction of the linkage mechanism 22, so as to ensure that the drive mechanism 21 drives the swing arm 30 to swing along the designed path through the linkage mechanism 22.

[0108] Continue to refer to the attached Figures 6A to 7 , the drive module 20 of the present invention further includes a pulse unit 24. When the drive mechanism 21 drives each swing arm 30 to swing through each linkage mechanism 22, the pulse unit 24 can generate a pulse signal to allow the drive mechanism 21 to accurately adjust the relative distance between each group of magnetic elements 40 and the flywheel 400 based on the pulse signal.

[0109] Specifically, the pulse unit 24 includes a grid element 241 and an infrared emission and reception element 242. The grid element 241 further includes a turntable 2411 and a plurality of grid arms 2412, and the grid element 241 has a plurality of optical path channels 2413. Each grid arm 2412 extends integrally outward from the periphery of the turntable 2411 at intervals and in a ring shape to form the optical path channels 2413 between adjacent two grid arms 2412. The turntable 2411 of the grid element 241 is installed on the output shaft 2111 of the drive motor 211 of the drive mechanism 21 to drive the grid element 241 to rotate when the drive motor 211 drives each linkage mechanism 22 through the gear set 212. The infrared emission and reception element 242 has a transmitting part 2421 and a receiving part 2422. The transmitting part 2421 and the receiving part 2422 are respectively held on opposite sides of the grid arm 2412 of the grid element 241, and the transmitting part 2421 and the receiving part 2422 correspond to each other.

[0110] The emission part 2421 of the infrared emission and reception element 242 is arranged to be able to continuously emit infrared light to the reception part 2422. When the grid element 241 rotates to make the optical path channel 2413 of the grid element 241 correspond to the emission part 2421 and the reception part 2422 of the infrared emission and reception element 242, the infrared light emitted by the emission part 2421 is allowed to pass through the optical path channel 2413 of the grid element 241 so as to be received by the reception part 2422. Correspondingly, when the grid element 241 rotates to make the grid arm 2412 of the grid element 241 correspond to the emission part 2421 and the reception part 2422 of the infrared emission and reception element 242, the infrared light emitted by the emission part 2421 is blocked from passing through the grid arm 2412 of the grid element 241 and cannot be received by the reception part 2422. In this way, the pulse unit 24 can generate a pulse signal, and based on the pulse signal, the swing amplitude of each swing arm 30 can be determined, and further, the relative distance between each group of the magnetic elements 40 and the flywheel 400 can be determined.

[0111] It is worth mentioning that the grid element 241 is drivably mounted on the output shaft 2111 of the drive motor 211 of the drive mechanism 21. In this way, the swing amplitude of the swing arm 30 driven by the drive mechanism 21 through the linkage mechanism 22 corresponds to the number of turns of the grid element 241 rotated by the drive mechanism 21, and the number of turns of the grid element 241 corresponds to the number of pulse signals generated by the infrared emission and reception element 242. Thus, by detecting the number of pulse signals generated by the pulse unit 24, the swing amplitude of the swing arm 30 driven by the drive mechanism 21 through the linkage mechanism 22 can be accurately determined, and further, the drive mechanism 21 can accurately adjust the distance between each group of the magnetic elements 40 and the flywheel 400 based on the pulse signals generated by the pulse unit 24.

[0112] It is worth mentioning that the number of the grid arms 2412 and the optical path channels 2413 of the grid element 241 is not limited in the internal magnetic control device 100 of the present invention, and the more the number of the grid arms 2412 and the optical path channels 2413 of the grid element 241, the more pulse signals are generated when the drive mechanism 21 drives the grid element 241 to rotate one week. Correspondingly, the drive mechanism 21 can more accurately adjust the distance between each group of the magnetic elements 40 and the flywheel 400 based on the pulse signals generated by the pulse unit 24. For example, in the attached Figures 2 to 8BIn this specific example of the internal magnetron device 100 shown, the number of the grid arms 2412 of the grid element 241 and the number of the optical path channels 2413 are both 16.

[0113] Preferably, the drive module 20 of the present invention further includes a circuit board 25, wherein the infrared transmitting and receiving element 242 of the pulse unit 24 is mounted on the circuit board 25, and the drive motor 211 of the drive mechanism 21 is electrically connected to the circuit board 25.

[0114] Appendix Figures 9A to 9E The assembly process of the internal magnetron device 100 of the present invention is shown. Specifically, refer to Appendix Figure 9A , and a set of the magnetic elements 40 is arranged on the swing arm 30. Refer to Appendix Figure 9B , and the pivot ends 31 of the two swing arms 30 are respectively mounted on the edge of the second housing 12. Refer to Appendix Figure 9C , the first housing 11 is mounted on the second housing 12 to allow the first housing 11 and the second housing 12 to form the magnetron housing 10, and the housing space 101 and the peripheral opening 102 are formed between the first housing 11 and the second housing 12, wherein each swing arm 30 is swingably held in the peripheral opening 102 of the magnetron housing 10. At this time, the first mounting posts 112 of the first housing 11 and the second mounting posts 122 of the second housing 12 limit the amplitude of the outward swing of the swing arm 30. Refer to Appendix Figure 9D and Figure 9E , the modular drive module 20 is installed in the housing space 101 of the magnetron housing 10 through the installation channel 104 of the magnetron housing 10, and the linkage mechanism 22 of the drive module 20 can extend from the housing space 101 of the magnetron housing 10 to the peripheral opening 102 through the gap formed between the first ring body 111 of the first housing 11 and the second ring body 121 of the second housing 12 for being rotatably mounted on the driven end 32 of the swing arm 30, thus assembling the internal magnetron device 100.

[0115] Specifically, in an embodiment of the present invention, first, they are respectively rotatably mounted on the end of the linkage mechanism 22 of the assembly 50; second, after allowing the assembly 50 to move to the peripheral opening 102 of the magnetron housing 10 through the gap formed between the first ring body 111 of the first housing 11 and the second ring body 121 of the second housing 12, it is fixedly mounted on the driven end 32 of the swing arm 30, thus rotatably mounting the driven end 32 of the swing arm 30 and the end of the linkage mechanism 22.

[0117] Optionally, in another embodiment of the present invention, first, allow the end of the linkage mechanism 22 of the drive module 20 to move through the gap formed between the first ring body 111 of the first housing 11 and the second ring body 121 of the second housing 12 to the peripheral opening 102 of the magnetic control housing 10; second, mount the assembly 50 at the driven end 32 of the swing arm 30; third, rotatably mount the assembly 50 at the end of the linkage mechanism 22, so as to rotatably mount the driven end 32 of the swing arm 30 and the end of the linkage mechanism 22.
