Description

Technical Field

[0001] The utility model relates to the field of fitness, and particularly to an internally magnetically controlled device capable of generating electricity and fitness equipment. Background Art

[0002] With the continuous improvement of living standards and health awareness, fitness equipment such as spinning bikes has become popular. When a user operates the fitness equipment, the fitness equipment can provide a load to help the user achieve the purpose of fitness. In order to have different fitness effects, the load of the fitness equipment can be adjusted. Usually, the way to adjust the load of the fitness equipment is to change the relative position between the magnet arranged on the swing arm and the flywheel. When the swing arm swings to a position where the distance between the magnet and the flywheel is small, the fitness equipment can have a large load. Correspondingly, when the swing arm swings to a position where the distance between the magnet and the flywheel is large, the fitness equipment can have a small load. Since the swing of the swing arm is driven by a motor, the existing fitness equipment needs to be connected to the mains power to supply electrical energy to the motor by the mains power. This results in that the existing fitness equipment has to be equipped with a connecting wire. The setting of this connecting wire not only affects the aesthetics of the fitness equipment, but also limits the layout position of the fitness equipment indoors, that is, the fitness equipment can only be arranged at a preset socket position indoors.

That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0037] Referring to the attached drawings of the specification of the present utility model Figures 1 to 7 , a power-generable magnetic control device according to a preferred embodiment of the present utility model will be disclosed and described hereinafter. The magnetic control device includes a support unit 10, a magnetic control unit 20 and a flywheel unit 30 respectively disposed on the support unit 10. The magnetic control unit 20 is configured to enable the flywheel unit 30 to obtain a load to help the user achieve the purpose of fitness. The flywheel unit 30 is configured to be capable of generating electricity to provide electrical energy for the fitness equipment to which the magnetic control device is applied, so that the fitness equipment can be disconnected from the mains power and get rid of the limitation of the use site.

[0038] Specifically, the flywheel unit 30 includes a set of coils 31, a coil bracket 32, at least one first magnetic element 33 and a flywheel 34.

[0039] Reference appendix Figure 1 、 Figure 4 、 Figure 6 and Figure 7 ,wherein the coil 31 is wound around the coil support 32. For example, in this specific example of the magnetic control device of the present utility model shown in the appendix Figures 1 to 7 In this specific example of the magnetic control device of the present utility model shown, the coil support 32 includes a central ring body 321 and a group of winding arm bodies 322. Each of the winding arm bodies 322 extends radially outward integrally from the central ring body 321, and each of the coils 31 is wound around each of the winding arm bodies 322 of the coil support 32, so that the coil 31 is wound around the coil support 32. Reference appendix Figure 4 ,In order to prevent the coil 31 from sliding outward along the winding arm body 321 of the coil support 32, the end size of the winding arm body 322 becomes larger, so that the size of the end of the winding arm body 321 is larger than the inner diameter size of the coil 31. In this way, the end of the winding arm body 322 can prevent the coil 31 from sliding. For example, the coil support 32 can be provided with a blocking arm 323 at the end of each of the winding arm bodies 322. The extending direction of the blocking arm 323 is substantially perpendicular to the extending direction of the winding arm body 322, and the middle of the blocking arm 323 is connected to the end of the winding arm body 322, that is, the blocking arm 323 and the winding arm body 322 are in a "T" shape, so that the end size of the winding arm body 322 becomes larger.

[0040] In some embodiments of the magnetic control device of the present utility model, the coil support 32 is an injection molded part, and the central ring body 321, each of the winding arm bodies 322 and each of the blocking arms 323 are integrally formed. There may be a gap 324 between two adjacent blocking arms 323 to facilitate a complete wire to be wound around each of the winding arm bodies 322 to form each of the coils 31.

[0041] It is worth mentioning that the number of the winding arm bodies 322 of the coil support 32 is not limited in the magnetic control device of the present utility model and is selected according to needs. It should be noted that the number of the coils 31 is the same as the number of the winding arm bodies 322 of the coil support 32, that is, the number of the winding arm bodies 322 determines the number of the coils 31. Since the data of the coils 31 is related to the power generation amount, when the magnetic control device is specifically applied, the number of the winding arm bodies 322 of the coil support 32 can be selected according to the required power of the fitness equipment.

[0042] The flywheel 34 is rotatably arranged on the support unit 10, and the flywheel 34 has a flywheel space 341. Reference appendix Figures 1 to 7, the flywheel 34 includes a wheel disc 342, a wheel ring 343 and a conductor 344. The wheel ring 343 is disposed at the edge of the wheel disc 342 on one side of the wheel disc 342. For example, the wheel ring 343 extends integrally from the edge of the wheel disc 342 to one side. In this way, the flywheel 34 can form the flywheel space 341 between the wheel disc 342 and the wheel ring 343, and the conductor 344 is sleeved on the outer side of the wheel ring 343. The conductor 344 can be an aluminum ring, which has good electrical conductivity. In a specific example of the present invention, the inner diameter dimension of the conductor 344 is the same as the outer diameter dimension of the wheel ring 343. Based on the frictional force generated between the inner wall of the conductor 344 and the outer wall of the wheel ring 343, the conductor 344 can be fixedly sleeved on the outer side of the wheel ring 343 so that the conductor 344 and the wheel ring 343 can rotate synchronously.

[0043] The first magnetic element 33 is disposed on the wheel ring 343 of the flywheel 34, and the first magnetic element 33 is located in the flywheel space 341 of the flywheel 34. In some embodiments of the magnetic control device of the present invention, the outer side surface of the first magnetic element 33 can be bonded to the inner wall of the wheel ring 343 of the flywheel 34 by glue, so that the first magnetic element 33 is disposed on the flywheel 34 in a manner of being located in the flywheel space 341 of the flywheel 34. In some other embodiments of the present invention, when the number of the first magnetic elements 33 is one and is implemented as a ring, based on the frictional force generated between the inner wall of the wheel ring 343 of the flywheel 34 and the outer side surface of the first magnetic element 33, the first magnetic element 33 can be disposed on the flywheel 34 in a manner of being located in the flywheel space 341 of the flywheel 34.

[0044] It is worth mentioning that the number of the first magnetic elements 33 is not limited in the magnetic control device of the present invention and is selected according to needs.

[0045] The coil bracket 32 is suspended in the flywheel space 341 of the flywheel 34. In this way, the coil bracket 32 suspends the coil 31 in the flywheel space 341 of the flywheel 34, and the coil 31 and the first magnetic element 33 are adjacent. Thus, when the flywheel 34 drives the first magnetic element 33 to rotate, the coil 31 can cut the magnetic induction lines of the first magnetic element 33 to generate current. In this way, the flywheel unit 30 can generate electricity.

[0046] Refer to the appendix Figure 1 、 Figure 4 、 Figure 6 and Figure 7, the magnetic control unit 20 is disposed adjacent to the conductor 344 of the flywheel 34, so that when the flywheel 34 rotates, the conductor 344 of the flywheel 34 can cut the magnetic induction lines of the magnetic control unit 20 to generate eddy currents, thereby obtaining a load, and further helping the user achieve the purpose of fitness.

[0047] That is to say, when the user drives the flywheel 34 to rotate through the fitness equipment, the conductor 344 of the flywheel 34 can cut the magnetic induction lines of the magnetic control unit 20 to allow the magnetic control device to be loaded, thereby helping the user achieve the purpose of fitness. At the same time, the coil 31 can cut the magnetic induction lines of the first magnetic element 33 to generate current, thereby realizing power generation.

[0048] Continue to refer to the appendix Figures 1 to 7 , the support unit 10 includes a first support arm 11 and a second support arm 12, and the first support arm 11 and the second support arm 12 are arranged at intervals from each other. The magnetic control device includes an assembly shaft 40, one end of the assembly shaft 40 is rotatably mounted on the first support arm 11, and the other end is rotatably mounted on the second support arm 12. The coil bracket 32 has a bracket through hole 325, and the inner diameter dimension of the bracket through hole 325 is larger than the outer diameter dimension of the assembly shaft 40. The coil bracket 32 is sleeved on the middle part of the assembly shaft 40 in such a way that the middle part of the assembly shaft 40 penetrates through the bracket through hole 325, and the coil bracket 32 is arranged to remain stationary relative to the support unit 10. The disk 342 of the flywheel 34 has a disk through hole 3421, and the flywheel 34 is fixedly sleeved on the assembly shaft 40 in such a way that the middle part of the assembly shaft 40 penetrates through the disk through hole 3421. In this way, the assembly shaft 40 and the flywheel 34 can rotate synchronously. When the user drives one end of the assembly shaft 40 through the fitness equipment, the assembly shaft 40 drives the flywheel 34 and the first magnetic element 33 to rotate relative to the support unit 10 and the coil bracket 32, so as to allow the conductor 344 of the flywheel 34 to cut the magnetic induction lines of the magnetic control unit 20 to obtain a load, and at the same time allow the coil 31 to cut the magnetic induction lines of the first magnetic element 33 to generate current.

[0049] Refer to the appendix Figure 3, the first support arm 11 includes a first vertical plate 111, a first flange 112, and a first bearing 113. The first flange 112 has a first flange through-hole 1121, and the outer end of the first flange 112 is fixedly connected to the first vertical plate 111. The inner side of the bearing of the first bearing 113 is fixedly sleeved on one end of the assembly shaft 40, and the outer side of the bearing of the first bearing 113 is fixedly arranged on the inner wall of the first flange 112 for forming the first flange through-hole 1121. In this way, this end of the assembly shaft 40 penetrates into the first flange through-hole 1121 of the first flange 112, so that this end of the assembly shaft 40 is rotatably mounted on the first support arm 11. For example, based on friction, the inner side of the bearing of the first bearing 113 can be fixedly sleeved on one end of the assembly shaft 40, and the outer side of the bearing of the first bearing 113 can be fixedly arranged on the inner wall of the first flange 112 for forming the first flange through-hole 1121. The inner end of the first flange 112 is fixedly connected to the central ring body 321 of the coil bracket 32. In this way, the coil bracket 32 is sleeved on the middle part of the assembly shaft 40, and the coil bracket 32 is arranged to remain stationary relative to the support unit 10. Thus, when the user drives one end of the assembly shaft 40 through the fitness equipment to drive the flywheel 34 and the first magnetic element 33 to rotate by the assembly shaft 40, the coil bracket 32 and the coil 31 remain stationary to allow the coil 31 to cut the magnetic induction lines of the first magnetic element 33 to generate an electric current.

[0050] Preferably, the first vertical plate 111 has a first vertical plate through-hole 1111, and the position of the first vertical plate through-hole 1111 of the first vertical plate 111 corresponds to the position of the first flange through-hole 1121 of the first flange 112. In this way, the first vertical plate through-hole 1111 of the first vertical plate 111 can avoid the assembly shaft 40 and prevent the assembly shaft 40 from contacting or colliding with the first vertical plate 111.

[0051] The specific connection manner between the first vertical plate 111 and the first flange 112 can be as Figure 1 and Figure 3As shown, the outer end of the first flange 112 is retracted to form an outer end extending portion 1122. After the outer end extending portion 1122 of the first flange 112 extends into the first vertical plate through hole 1111 of the first vertical plate 111, a set of screws can lock the first vertical plate 111 and the first flange 112, so that the outer end of the first flange 112 can be reliably and fixedly connected to the first vertical plate 111. Preferably, the outer diameter dimension of the outer end extending portion 1122 of the first flange 112 is the same as the inner diameter dimension of the first vertical plate through hole 1111 of the first vertical plate 111, so that the outer wall of the outer end extending portion 1122 of the first flange 1122 and the inner wall of the first vertical plate 111 for defining the first vertical plate through hole 1111 can be mutually attached. In this way, a set of screws can reliably lock the first vertical plate 111 and the first flange 112.

[0052] The specific connection manner between the first flange 112 and the central ring body 321 of the coil support 32 can be as Figure 1 and Figure 3 As shown, the inner end of the first flange 112 is retracted to form an inner end extending portion 1123. The outer diameter dimension of the inner end extending portion 1123 of the first flange 112 is the same as the inner diameter dimension of the central ring body 321, so that based on the frictional force between the outer wall of the inner end extending portion 1123 of the first flange 112 and the inner wall of the central ring body 321, the first flange 112 and the central ring body 321 can be reliably installed.

[0053] Continue to refer to the appendix Figure 3, the second support arm 12 includes a second vertical plate 121, a second flange 122, and a second bearing 123. The second vertical plate 121 has a second vertical plate perforation 1211. The second flange 122 includes a flange plate 1221 and a flange arm 1222 integrally extending outward from one side of the flange plate 1221. The second flange 122 further has a second flange perforation 1223 that penetrates through the flange plate 1221 and the flange arm 1222. After the flange arm 1222 of the second flange 122 passes through the second vertical plate perforation 1211 of the second vertical plate 121, a set of screws can lock the second vertical plate 121 and the flange plate 1221. The inner side of the bearing of the second bearing 123 is fixedly sleeved on one end of the assembly shaft 40, and the outer side of the bearing of the second bearing 123 is fixedly arranged on the inner wall of the second flange 122 for forming the second flange perforation 1223. In this way, this end of the assembly shaft 40 penetrates into the second flange perforation 1223 of the second flange 122, so that this end of the assembly shaft 40 is rotatably mounted on the second support arm 12. Preferably, the outer diameter dimension of the flange arm 1222 of the second flange 122 is the same as the inner diameter dimension of the second vertical plate perforation 1211 of the second vertical plate 121, so that the outer wall of the flange arm 1222 and the inner wall of the second vertical plate 121 for defining the second vertical plate perforation 1211 can be mutually attached. In this way, a set of screws can reliably lock the second vertical plate 121 and the second flange 122.

[0054] Further, referring to the attached Figure 1 , Figure 2 , Figure 4 and Figure 5 , the support unit 10 includes a series of support columns 13. Opposite ends of these support columns 13 are respectively arranged on the first vertical plate 111 of the first support arm 11 and the second vertical plate 121 of the second support arm 12, so as to keep the relative positions of the first support arm 11 and the second support arm 12 unchanged. In this specific example of the magnetron device of the present invention shown in the attached Figures 1 to 7 , screws can mount one end of the support column 13 on the first vertical plate 111 of the first support arm 11 and mount the other end of the support column 13 on the second vertical plate 121 of the second support arm 12, so that opposite ends of the support column 13 are respectively arranged on the first vertical plate 111 of the first support arm 11 and the second vertical plate 121 of the second support arm 12.

[0055] Further, referring to the attached Figures 4 to 7, the magnetic control unit 20 includes a swing arm 21 and at least one magnetic element 22 (the second magnetic element 22) disposed on the swing arm 21. The swing arm 21 is swingably disposed on the support unit 10, and the magnetic element 22 (the second magnetic element 22) is located between the swing arm 21 and the conductor 344 of the flywheel 34. When the flywheel 34 rotates, the conductor 344 cuts the magnetic induction lines of the magnetic element 22 (the second magnetic element 22) to generate eddy currents, thereby obtaining a load to help the user achieve the purpose of fitness. Preferably, the swing arm 21 is arc-shaped. In embodiments where the number of the magnetic elements 22 (the second magnetic element 22) is multiple, these magnetic elements 22 (the second magnetic element 22) are arranged in an arc along the extending direction of the swing arm 21. Therefore, the arrangement shape of the magnetic elements 22 (the second magnetic element 22) matches the shape of the conductor 344 of the flywheel 344.

[0056] The specific manner in which the magnetic element 22 (the second magnetic element 22) is disposed on the swing arm 21 is not limited in the magnetic control device of the present invention. For example, in some embodiments, one side of the magnetic element 22 (the second magnetic element 22) can be bonded to one side of the swing arm 21 through glue, so that the magnetic element 22 (the second magnetic element 22) is disposed on the swing arm 21.

[0057] Opposite sides of one end of the swing arm 21 are respectively rotatably mounted on the first vertical plate 111 of the first support arm 11 and the second vertical plate 121 of the second support arm 12, so that the swing arm 21 is swingably disposed on the support unit 10.

[0058] The specific manner in which opposite sides of this end of the swing arm 21 are respectively rotatably mounted on the first vertical plate 111 and the second vertical plate 121 is as Figure 4 and Figure 5 shown. This end of the swing arm 21 has a swing arm through hole 211. The magnetic control device includes a swing arm rotating shaft 50. The middle part of the swing arm rotating shaft 50 is located in the swing arm through hole 211 of the swing arm 21, and the swing arm 21 can rotate around the swing arm rotating shaft 50. Opposite ends of the swing arm rotating shaft 50 are respectively mounted on the first vertical plate 111 and the second vertical plate 121. In this way, opposite sides of this end of the swing arm 21 are respectively rotatably mounted on the first vertical plate 111 and the second vertical plate 121.

[0059] In order to drive the swing arm 21 to swing and adjust the distance between the magnetic element 22 (the second magnetic element 22) and the conductor 344 of the flywheel 34, refer to the attached Figure 6 and Figure 7, the magneto - control unit 20 includes a driving part 23, at least one first connecting arm 24 and at least one second connecting arm 25. Wherein the driving part 23 is arranged on the supporting unit 10. For example, the opposite two sides of the driving part 23 can be respectively fastened to the first vertical plate 111 of the first supporting arm 11 and the second vertical plate 121 of the second supporting arm 12 by screws to arrange the driving part 23 on the supporting unit 10. One end of the first connecting arm 24 is fixedly installed on an output shaft of the driving part 23. The opposite two ends of the second connecting arm 25 are respectively rotatably installed on the other end of the first connecting arm 24 and the driven end of the swing arm 21. The driven end of the swing arm 21 is the end of the swing arm 21 far from the end of the swing arm 21 for rotatably connecting to the supporting unit 10. The driving part 23 can drive the swing arm 21 to swing through the first connecting arm 24 and the second connecting arm 25.

[0060] Specifically, when the output shaft of the driving part 23 rotates in one direction to output power, the output shaft of the driving part 23 drives the first connecting arm 24 to swing in one direction. At this time, the first connecting arm 24 pulls the swing arm 21 and the magnetic element 22 (second magnetic element 22) away from the conductor 344 of the flywheel 34 through the second connecting arm 25 to increase the distance between the magnetic element 22 (second magnetic element 22) and the conductor 344. At this time, the magneto - control device has a smaller load. Correspondingly, when the output shaft of the driving part 23 rotates in the other direction to output power, the output shaft of the driving part 23 drives the first connecting arm 24 to swing in the other direction. At this time, the first connecting arm 24 pushes the swing arm 21 and the magnetic element 22 (second magnetic element 22) towards the conductor 344 of the flywheel 34 through the second connecting arm 24 to decrease the distance between the magnetic element 22 (second magnetic element 22) and the conductor 344. At this time, the magneto - control device has a larger load.

[0061] In the appendix Figures 1 to 7In this specific example of the magneto-control device of the present utility model shown, the magneto-control unit 20 includes two of the first connecting arms 24 and two of the second connecting arms 25. One end portions of the two first connecting arms 24 are respectively fixedly mounted on the output shafts on opposite sides of the driving portion 23. One end portion of one second connecting arm 25 is rotatably mounted on the driven end of the swing arm 21 on one side of the swing arm 21, and the other end portion is rotatably mounted on the end portion of the corresponding first connecting arm 24 away from the driving portion 23. One end portion of the other second connecting arm 25 is rotatably mounted on the driven end of the swing arm 21 on the other side of the swing arm 21, and the other end portion is rotatably mounted on the end portion of the corresponding first connecting arm 24 away from the driving portion 23. In this way, when the driving portion 23 drives the swing arm 21 to swing through the first connecting arm 24 and the second connecting arm 25, the forces on opposite sides of the swing arm 21 are balanced, preventing the swing arm 21 from tilting.

[0062] Preferably, the magneto-control unit 20 includes a resistor 26 and a third connecting arm 27. The resistor 26 includes a fixed portion 261 and a movable portion 262 slidably mounted on the fixed portion 261. The fixed portion 261 of the resistor 26 is disposed on the first vertical plate 111 of the first support arm 11 of the support unit 10. Opposite ends of the third connecting arm 27 are respectively rotatably mounted on the driven end of the swing arm 21 and the movable portion 262 of the resistor 26. When the driving portion 23 drives the swing arm 21 to swing through the first connecting arm 24 and the second connecting arm 25, the swing arm 21 drives the movable portion 262 to slide relative to the fixed portion 261 through the third connecting arm 27 to change the resistance value of the resistor 26. It can be understood that the resistance value of the resistor 26 and the swinging position of the swing arm 21 are in one-to-one correspondence. Therefore, the swinging position of the swing arm 21 can be determined by detecting the resistance value of the resistor 26.

[0063] Specifically, the first vertical plate 111 of the first support arm 11 has an assembly channel 1112, which penetrates through opposite sides of the first vertical plate 111. Wherein, the circuit board 2611 of the fixed part 261 of the resistor 26 is located outside the first vertical plate 111, and the main body 2612 of the fixed part 261 extends towards the space between the first vertical plate 111 and the second vertical plate 121 through the assembly channel 1112 of the first vertical plate 111. Preferably, the shape and size of the assembly channel 1112 of the first vertical plate 111 are consistent with the shape and size of the main body 2612 of the fixed part 261, and the size of the circuit board 2611 of the fixed part 261 is larger than the size of the assembly channel 1112 of the first vertical plate 111. In this way, the main body 2612 of the fixed part 261 can be snapped into the assembly channel 1112 of the first vertical plate 111, so that the fixed part 261 is reliably mounted on the first vertical plate 111.

[0064] The magneto-control device further includes a fitting 60, which is mounted on the first vertical plate 111. The circuit board 2611 of the fixed part 261 is clamped between the first vertical plate 111 and the fitting 60, so that the fixed part 261 is reliably mounted on the first vertical plate 111. In some examples of the magneto-control device of the present utility model, the fitting 60 and the first vertical plate 111 can be locked by a set of screws.

[0065] Furthermore, the magneto-control device includes a circuit board 70. Wherein, the coil 31, the driving part 23 and the circuit board 2611 of the fixed part 261 of the resistor 26 are respectively connected to the circuit board 70. In this way, the electric energy generated by the coil 31 can be supplied to the circuit board 70, and processed such as shaping by the circuit board 70. The circuit board 70 can control the working state of the driving part 23 according to the resistance value fed back by the resistor 26, so that the swing arm 21 drives the magnetic element 22 and the second magnetic element 22 to swing to a desired position.

[0066] Preferably, the circuit board 70 is arranged on the first support arm 11 of the support unit 10. For example, the circuit board 70 can be arranged outside the first vertical plate 111 of the first support arm 11. In this way, the vehicle factory can conveniently replace the circuit board 70 as needed and connect the circuit board 70 to the coil 31, the driving part 23, and the circuit board 2611 without disassembling the magneto-control device as a whole. It can be understood that after replacing the circuit board 70, the magneto-control device can have different performances.

[0067] Further, the magnetic control device includes at least one storage battery 80, wherein the storage battery 80 is connected to the circuit board 70, and the circuit board 70 can store the electric energy generated by the coil 31 in the storage battery 80, and can also supply the electric energy stored in the storage battery 80 to the driving part 23, so as to allow the driving part 23 to drive the swing arm 21 and the magnetic element 22 (the second magnetic element 22) to swing through the first connecting arm 24 and the second connecting arm 25.

[0068] Preferably, the storage battery 80 is arranged on the support unit 10. Specifically, the magnetic control device further includes a battery holder 90 which has a receiving groove 91. The battery holder 90 can be mounted on the second vertical plate 121 of the second support arm 12 of the support unit 10 by, but not limited to, screws. One end of the storage battery 80 can be inserted into the receiving groove 91 of the battery holder 90. In this way, the storage battery 80 can be arranged on the support unit 10. More preferably, the battery holder 90 is arranged inside the second vertical plate 121, so that the battery holder 90 is located in the space between the first vertical plate 111 and the second vertical plate 121, and thus the storage battery 80 is located in the space between the first vertical plate 111 and the second vertical plate 121. More preferably, the battery holder 90 and the storage battery 80 are located above the driving part 23, so that the structure of the magnetic control device is compact, which is beneficial to saving space and making the magnetic control device miniaturized.

[0069] Attached Figures 8 to 13 shows a deformation example of the magnetic control device of the above-mentioned preferred embodiment. Different from the magnetic control device shown in Attached Figures 1 to 7 shown, in this deformation example of the magnetic control device shown in Attached Figures 8 to 13 shown, the magnetic control unit 20 includes a swing arm 21, at least one magnetic element 22, a driving part 23, a module housing 28 and a connecting rod 29. The swing arm 21 has a pivoting end 211 and a driven end 212 corresponding to the pivoting end 211. The pivoting end 211 of the swing arm 21 is rotatably arranged on the module housing 28. The magnetic element 22 is arranged on the swing arm 21. The driving part 23 is arranged on the module housing 28. The connecting rod 29 connects the driving part 23 and the driven end 212 of the swing arm 21. The module housing 28 is arranged on the support unit 10. The magnetic element 22 (the second magnetic element 22) is located between the swing arm 21 and the conductor 344 of the flywheel 34. When the flywheel 34 rotates, the conductor 344 cuts the magnetic induction lines of the magnetic element 22 (the second magnetic element 22) to generate eddy current, thereby obtaining a load to help the user achieve the purpose of fitness.

[0070] Further, the module housing 28 has a housing space 281 and a housing opening 282 communicating with the housing space 281. Both the swing arm 21 and the driving part 23 are located in the housing space 281 of the module housing 28, and the magnetic element 22, the second magnetic element 22 faces the housing opening 282 of the module housing 28, wherein the housing opening 282 of the module housing 28 faces the outside of the conductor 344 of the flywheel 34.

[0071] Furthermore, the module housing 28 includes a first housing 283 and a second housing 284. The first housing 283 and the second housing 284 are installed with each other to form the housing space 281 and the housing opening 282 therebetween. For example, in some embodiments, the first housing 283 and the second housing 284 can be installed by screws. Opposite sides of the pivot end 211 of the swing arm 21 are rotatably installed on the first housing 283 and the second housing 284 at the edge of the housing opening 282 of the module housing 28 respectively. In this way, the swing arm 21 is used to hold the magnetic element 22, the second magnetic element 22 at a position facing the housing opening 282 of the module housing 28.

[0072] Preferably, the first housing 283 has a first notch 2831 and an arc-shaped first blocking portion 2832 located inside the first notch 2831. The second housing 284 has a second notch 3841 and an arc-shaped second blocking portion 2842 located inside the second notch 3841. The position of the first notch 2831 of the first housing 283 corresponds to the position of the second notch 3841 of the second housing 284 to form the housing opening 282 between the first housing 283 and the second housing 284. The position of the first blocking portion 2832 of the first housing 283 corresponds to the position of the second blocking portion 2842 of the second housing 284, and both are located inside the swing arm 21 to limit the maximum distance of the inward movement of the swing arm 21. In this way, it is beneficial to avoid "jamming" at the connection position of the connecting rod 29 and the driving part 23, making the swinging process of the swing arm 21 smoother.

[0073] The specific manner in which the module housing 28 is arranged on the support unit 10 is as Figure 8 and Figure 9As shown, the module housing 28 has at least one housing perforation 285. Each of the housing perforations 285 extends from the outside of the first housing 283 to the outside of the second housing 284. The middle parts of the respective support columns 13 are respectively located in the respective housing perforations 285 of the module housing 28. One end of each of the support columns 13 can be locked to the first vertical plate 111 of the first support arm 11 by screws, and the other end of each of the support columns 13 is respectively locked to the second vertical plate 121 of the second support arm 12 by screws. Thus, the module housing 28 is arranged on the support unit 10.

[0074] Refer to the attached Figures 8 to 11 , the driving part 23 includes a driving motor 231, a set of transmission gears 232 and a sector gear 233.

[0075] The driving motor 231 is fixedly installed in the housing space 281 of the module housing 28. For example, the first housing 283 has an assembly wall 2833, and the assembly wall 2833 has a wall hole 28331. After the worm 2311 of the driving motor 231 passes through the wall hole 28331 of the assembly wall 2833 of the first housing 283, screws can lock the driving motor 231 to the assembly wall 2833. At the same time, after the first housing 283 and the second housing 284 are installed with each other, the first housing 283 and the second housing 284 clamp the driving motor 231. Thus, the driving motor 231 is fixedly installed in the housing space 281 of the module housing 28.

[0076] The opposite sides of each of the transmission gears 232 are respectively rotatably installed on the first housing 283 and the second housing 284, so that these transmission gears 232 are respectively rotatably held in the housing space 281 of the module housing 28, and two adjacent transmission gears 232 mesh with each other. One transmission gear 232 meshes with the worm 2311 of the driving motor 231.

[0077] The opposite sides of the sector gear 233 are respectively rotatably installed on the first housing 283 and the second housing 284, so that the sector gear 233 is rotatably held in the housing space 281 of the module housing 28, and the wheel side 2331 of the sector gear 233 meshes with one of the transmission gears 232.

[0078] One end of the connecting rod 29 is rotatably mounted on the arm side 2332 of the sector gear 233, and the other end of the connecting rod 29 is rotatably mounted on the driven end 212 of the swing arm 21, so that the connecting rod 29 connects the driving part 23 and the driven end 212 of the swing arm 21.

[0079] Refer to the attached Figure 14 and Figure 15 , when the worm 2311 of the drive motor 231 rotates in one direction, the worm 2311 of the drive motor 231 drives the sector gear 233 to rotate in one direction through these transmission gear sets 232. At this time, the connecting rod 29 pulls the swing arm 21 and the magnetic element 22 (second magnetic element 22) away from the conductor 344 of the flywheel 34, so as to increase the distance between the magnetic element 22 (second magnetic element 22) and the conductor 344. At this time, the magneto-control device has a smaller load. Correspondingly, when the worm 2311 of the drive motor 231 rotates in the opposite direction, the worm 2311 of the drive motor 231 drives the sector gear 233 to rotate in the opposite direction through these transmission gears 232. At this time, the connecting rod 29 pushes the swing arm 21 and the magnetic element 22 (second magnetic element 22) towards the conductor 344 of the flywheel 34, so as to reduce the distance between the magnetic element 22 (second magnetic element 22) and the conductor 344. At this time, the magneto-control device has a larger load.

[0080] Different from the specific structure in which the movable part 262 of the resistor 26 of the magneto-control device shown in the attached Figures 1 to 7 is slidably arranged on the fixed part 261, in this specific example of the magneto-control device shown in the attached Figures 8 to 13 , the movable part 262 of the resistor 26 is rotatably arranged on the fixed part 261. The fixed part 261 is fixedly mounted on the first housing 283, and the movable part 262 is fixedly mounted on the sector gear 233. When the sector gear 233 is driven to rotate, the sector gear 233 drives the movable part 262 to rotate, so as to change the resistance value of the resistor 26. It can be understood that the resistance value of the resistor 26 and the swing position of the swing arm 21 are in one-to-one correspondence. Therefore, the swing position of the swing arm 21 can be determined by detecting the resistance value of the resistor 26.

[0081] Specifically, the first housing 283 has a housing mounting hole 2834 and a convex ring 2835 that surrounds the housing mounting hole 2834 and protrudes into the housing space 281. The sector gear 233 has a gear mounting hole 2333. The convex ring 2835 of the first housing 283 protrudes into the gear mounting hole 2333 of the sector gear 233, so that the sector gear 233 is rotatably held in the housing space 281 of the module housing 28, and the position of the gear mounting hole 2333 of the sector gear 233 corresponds to the position of the housing mounting hole 2834 of the first housing 283. The fixed portion 261 of the resistor 26 is fixedly mounted on the first housing 283 outside the first housing 283. The movable portion 262 extends through the housing mounting hole 2834 of the first housing 283 and is fixedly mounted on the gear mounting hole 2333 of the sector gear 233. Thus, when the sector gear 233 is driven to rotate, the sector gear 233 drives the movable portion 262 to rotate. Since the fixed portion 261 of the resistor 26 is mounted on the first housing 283 outside the first housing 283, the fixed portion 261 of the resistor 26 can be conveniently connected to the circuit board 70. Preferably, the first housing 283 has a groove 2836, and the fixed portion 261 of the resistor 26 is received in the groove 2836 of the first housing 283 to prevent the resistor 26 from protruding.

[0082] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and described in the embodiments. Without departing from the principle, any deformation or modification of the embodiments of the present invention is possible.
