Exercise apparatus

Technical Field

The utility model relates to the field of sports equipment, in particular to sports equipment.

Background

With the attention of people to the health, the sports equipment is more and more popular with consumers, and various kinds of sports equipment in the market are also endlessly available, especially indoor sports equipment such as a treadmill, a dynamic bicycle, an elliptical machine, a rowing machine and the like, which is not only a hot equipment in a gymnasium, but also popular with consumers who do household sports.

Most sports equipment on the market can detect the motion data of a user in the using process, such as motion speed, motion power, heat consumption, motion time and the like, and timely feed back the motion data to a user interface, so that the user can conveniently check the motion data in real time, and further the motion state can be mastered in real time. Moreover, for the quality evaluation of the sports equipment, the accuracy of the sports data directly determines the quality grade of the sports equipment, wherein the error amount between the actual sports power and the calibrated sports power is an important factor for evaluating the quality grade of the sports equipment.

The elliptical trainer is taken as an example for explanation, and comprises a main body and a resistance adjusting wheel, wherein the main body comprises a main body support, a driving wheel, two operating pieces, a driving belt and a control console, the driving wheel is arranged on the main body support, the resistance adjusting wheel comprises a resistance adjusting mechanism, a metal flywheel, a metal ring arranged on the metal flywheel, a position sensor for detecting the position of the resistance adjusting mechanism, a rotating speed and rotating speed sensor for detecting the rotating speed and a control module. The resistance adjusting mechanism is provided with a magnetic block, the metal flywheel is rotatably arranged on the outer side of the magnetic block of the resistance adjusting mechanism, and the metal ring is kept between the metal flywheel and the resistance adjusting mechanism. The distance between the magnetic block of the resistance adjusting mechanism and the inner surface of the metal flywheel is allowed to be adjusted, and a user can select different resistance grade instructions through a console of the elliptical machine to obtain different resistance feelings.

In an existing elliptical machine, different resistance level instructions correspond to different preset positions of the magnetic block of the resistance adjusting mechanism, the preset position of the magnetic block of the resistance adjusting mechanism corresponding to each resistance level instruction is a fixed position, and namely the distance between the magnetic block of the resistance adjusting mechanism corresponding to each resistance level instruction and the metal flywheel is a fixed distance. When a user uses the elliptical machine, the resistance level instruction is selected through the display screen of the console, if the resistance level instruction is in the '2 gear', the control module of the resistance adjusting mechanism receives the resistance level instruction and judges whether the position of the magnetic block of the resistance adjusting mechanism is the preset position corresponding to the '2 gear', and if the position of the magnetic block of the resistance adjusting mechanism is not in the preset position corresponding to the '2 gear', the magnetic block of the resistance adjusting mechanism is adjusted to the preset position corresponding to the '2 gear'.

After the user selects the resistance grade instruction, the user drives the operating part, the operating part drives the driving wheel to rotate, the driving wheel drives the metal flywheel to rotate relative to the resistance adjusting mechanism through the driving belt, and the rotating speed sensor acquires the rotating speed of the metal flywheel.

Before each elliptical machine leaves a factory, the relationship between the resistance level and the rotating speed and the calibration power is preset. Specifically, before the elliptical machine leaves the factory, one elliptical machine is measured, a corresponding relation between the resistance level and the rotation speed and the calibration power is obtained, and then the corresponding relation is applied to all elliptical machines leaving the factory. Therefore, after the user selects the resistance grade instruction, the resistance adjusting mechanism is adjusted to the preset position corresponding to the resistance grade instruction, the user drives the elliptical machine to rotate, the elliptical machine obtains the calibration power at the moment according to the resistance grade, the rotating speed and the corresponding relation between the resistance grade, the rotating speed and the calibration power at the moment, and meanwhile, the calibration power at the moment is displayed on a display screen of the console.

However, since each elliptical machine may have differences in the assembly process before leaving the factory, or differences between the same components, various uncertain factors inevitably cause differences between different elliptical machines. For example, when the magnetic blocks of the resistance adjusting mechanisms of different elliptical machines are in the same preset position, the resistance generated by the magnetic blocks may not be the same. Alternatively, the preset positions of different elliptical machines corresponding to the same resistance level command may be different. For example, when two elliptical machines are adjusted to "2 th gear", the distance between the magnetic block of the resistance adjusting mechanism of one elliptical machine and the metal flywheel may be 8 mm, and the distance between the magnetic block of the other elliptical machine and the metal flywheel may be 7 mm. However, when the user exercises at the same rotation speed and the same resistance level on two different elliptical machines, the power displayed by the console is the same calibrated power. However, the actual power of the user on the two elliptical machines with the difference is not the same. That is, there is necessarily a difference between the nominal power displayed on the display screen of the console of the elliptical machine and the actual power of the user. In other words, the power value presented to the user by the existing elliptical machine is not the actual power value of the user.

In the process of evaluating the product quality of the elliptical machine, the smaller the actual power and the calibrated power of the user are, the higher the quality grade of the elliptical machine is, the larger the difference between the actual power and the calibrated power of the user is, and the lower the quality grade of the elliptical machine is. Therefore, how to reduce the difference between the actual power and the calibrated power of the user becomes a difficult problem for many sports equipment manufacturers to overcome.

The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 5B of the drawings of the present application, an exercise apparatus 10000 according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the exercise apparatus 10000 includes an inner magnetic control device 100, an equipment rack 200, a pedaling device 300, a flywheel 400 and a torsion force detecting device 500.

The internal magnet control device 100 is mounted to the equipment rack 200, wherein the stepping device 300 is tiltably mounted to the equipment rack 200, wherein the flywheel 400 is rotatably mounted to the equipment rack 200 and is drivably connected to the stepping device 300, and the flywheel 400 is disposed around the outside of the internal magnet control device 100, wherein opposite ends of the torsion detecting device 500 are mounted to the internal magnet control device 100 and the equipment rack 200, respectively. When the user continuously steps on the stepping device 300 to drive the flywheel 400 to rotate relative to the internal magnetic control device 100 and the equipment rack 200, on one hand, the flywheel 400 continuously cuts the magnetic induction lines of the internal magnetic control device 100 to obtain a load, so that the user can achieve the purpose of body building through the exercise equipment 10000, on the other hand, the internal magnetic control device 100 is driven by the flywheel 400 to receive a torsion, and the torsion detection device 500 can detect the torsion received by the internal magnetic control device 100, so that the actual power of the user when the user exercises through the exercise equipment 10000 is obtained by the exercise equipment 10000 according to the torsion value fed back by the torsion detection device 500 subsequently.

It is worth mentioning that the sports apparatus 10000 shown in fig. 1 implemented as an elliptical machine is only exemplary and does not limit the specific type of the sports apparatus 10000 of the present invention. For example, in other examples of the present invention, the sports device 10000 may be a rowing machine, a spinning bike, or the like. It is understood that the exercise apparatus 10000 may not have the stepping device 300, and the exercise apparatus 10000 may achieve the purpose of exercise as long as the user is allowed to drive the flywheel 400 to rotate.

It can be understood that the exercise equipment 10000 has a fixed calibration power, and because of the assembling process of the exercise equipment 10000 and the error of the spare and accessory parts, the actual power of the user when exercising through the exercise equipment 10000 may be different from the calibration power of the exercise equipment 10000, the exercise equipment 10000 adjusts the state of the internal magnetic control device 100 by providing the torsion detection device 500 to detect the torsion of the user when exercising through the exercise equipment 10000 according to the torsion received by the internal magnetic control device 100, so as to correct the actual power of the user when exercising through the exercise equipment 10000, thus being beneficial to improving the efficiency of the user when exercising through the exercise equipment 10000.

It will be appreciated that the load that the flywheel 400 obtains when driven to rotate is related to the amount of magnetic induction lines that the flywheel 400 cuts through the inner magnet control device 100. Specifically, the more the flywheel 400 is driven to rotate, the greater the amount of magnetic induction lines of the inner magnetic control device 100 is cut, the greater the load that can be obtained by the flywheel 400, and at this time, the more effort the user needs to step on the stepping device 300. Accordingly, the smaller the amount of the magnetic induction lines of the inner magnetic control device 100 cut by the flywheel 400 when the flywheel 400 is driven to rotate, the smaller the load that can be obtained by the flywheel 400, and the more labor-saving the user can step on the stepping device 300.

It is worth mentioning that the load obtained by the flywheel 400 when driven to rotate is represented by the resistance value when the user steps on the stepping device 300, and the larger the load obtained by the flywheel 400 when driven to rotate is, the larger the resistance value when the user steps on the stepping device 300 is, and accordingly, the smaller the load obtained by the flywheel 400 when driven to rotate is, the smaller the resistance value when the user steps on the stepping device 300 is.

In order to satisfy different requirements of the user on the load of the flywheel 400 of the exercise device 10000 and to correct the actual power of the user when exercising through the exercise device 10000 to be consistent with the calibrated power, the internal magnetic control device 100 of the present invention is configured to be able to adjust the relative positions of the magnetic induction lines and the flywheel 400, such that the closer the position of the magnetic induction lines of the internal magnetic control device 100 is to the flywheel 400, the more the flywheel 400 is driven to rotate, the more the amount of the magnetic induction lines of the internal magnetic control device 100 is cut, and correspondingly, the more the position of the magnetic induction lines of the internal magnetic control device 100 is away from the flywheel 400, the less the amount of the magnetic induction lines of the internal magnetic control device 100 is cut when the flywheel 400 is driven to rotate. Therefore, by adjusting the relative position of the magnetic induction line of the internal magnetic control device 100 and the flywheel 400, on the one hand, the resistance value of the user when stepping on the stepping device 300 can be adjusted, and on the other hand, the actual power and the calibration power of the user when exercising through the exercise equipment 10000 can be corrected to be consistent.

Specifically, referring to fig. 5A and 5B, the internal magnetic control device 100 includes a magnetron housing 10, a driving unit 20, at least one swing arm 30, and at least one magnetic element 40. The magnetron housing 10 has a housing space 101 and a peripheral opening 102 communicating with the housing space 101. The driving unit 20 is disposed in the housing space 101 of the magnetron housing 10 for providing power. The 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 to the magnetron housing 10, and the driven end 32 of the swing arm 30 is drivably connected to the driving unit 20 to allow the driving unit 20 to drive the swing arm 30 to swing at the peripheral opening 102 of the magnetron housing 10. The magnetic element 40 is disposed on the swing arm 30 to allow the magnetic element 40 to provide a magnetic field environment at the peripheral opening 102 of the magnetron housing 10. The flywheel 400 surrounds the outer side of the magnetron housing 10 of the internal magnetic control device 100, and the peripheral opening 102 of the magnetron housing 10 corresponds to the inner side of the flywheel 20, so that 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 the magnetic elements 40 of the internal magnetic control device 100 to obtain a load.

It is worth mentioning that the number of the swing arms 30 of the internal magnetic control device 100 is not limited in the exercise apparatus 10000 of the present invention, for example, in the specific example shown in fig. 5A and 5B, the internal magnetic control device 100 includes two swing arms 30, the two swing arms 30 are held in the peripheral opening 102 of the magnetron housing 10 in a mutually central symmetrical manner, wherein each of the swing arms 30 is respectively provided with the magnetic element 40. Alternatively, in other specific examples of the exercise apparatus 10000 of the present invention, the inner magnetic control device 100 comprises three swing arms 30, the three swing arms 30 are held at the peripheral opening 102 of the magnetron housing 10 in a mutually central symmetrical manner, wherein each swing arm 30 is respectively provided with the magnetic element 40.

Preferably, the outer side of the swing arm 30 faces the peripheral opening 102 of the magnetron housing 10, and the magnetic element 40 is disposed on the outer side of the swing arm 30, so that the magnetic element 40 can be directly exposed to the peripheral opening 102 of the magnetron housing 10.

It is worth mentioning that the way the magnetic element 40 is arranged in the swing arm 30 is not limited in the sports apparatus 10000 of the present invention. For example, in a preferred example of the exercise apparatus 10000 of the present invention, the magnetic element 40 can be disposed on the swing arm 30 by gluing. Alternatively, in another example of the exercise apparatus 10000 of the present invention, the magnetic element 40 may be disposed on the swing arm 30 by being embedded.

It is worth mentioning that the number of the magnetic elements 40 provided to the swing arm 30 is not limited in the sporting apparatus 10000 of the present invention. For example, in this specific example shown in fig. 5A and 5B, three of the magnetic elements 40 are disposed at intervals to the swing arm 30, i.e., with a gap between adjacent magnetic elements 40.

Preferably, the swing arm 30 extends between the pivot end 31 and the driven end 32 in a curved manner, so that the swing arm 30 has an arc surface shape, and thus the shape of the outer side of the swing arm 30 is substantially the same as the shape of the periphery of the magnetron housing 10. Preferably, the magnetic element 40 is arc-shaped, and the shape of the inner side of the magnetic element 40 is consistent with the shape of the outer side of the swing arm 30, so as to reliably arrange the magnetic element 40 on the outer side of the swing arm 30.

With continued reference to fig. 5A and 5B, the magnetron housing 10 further includes a disk-shaped first housing 11 and a disk-shaped second housing 12, the first housing 11 has a first ring 111, the second housing 12 has a second ring 121, wherein the first housing 11 and the second housing 12 are mounted to each other in a manner that the first ring 111 and the second ring 121 correspond to each other, so as to form the housing space 101 on the inner side of the first ring 111 and the second ring 121, and form the peripheral opening 102 on the outer side of the first ring 111 and the second ring 121. Preferably, the first housing 11 and the second housing 12 are both made of plastic.

Further, a plurality of first mounting posts 112 are disposed on the edge of the first housing 11, a plurality of second mounting posts 122 are disposed on the edge of the second housing 12, and 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 respectively mounted and supported on each other to prevent the edge of the first housing 11 and the edge of the second housing 12 from being deformed. Preferably, screws are allowed to be mounted to the first mounting posts 112 of the first housing 11 and the second mounting posts 122 of the second housing 12 to lock the first housing 11 and the second housing 12 at the edges of the first housing 11 and the second housing 12.

Opposite sides of the pivot end 31 of the swing arm 30 are rotatably mounted on the edge of the first housing 11 and the edge of the second housing 12, respectively, so as to rotatably mount the pivot end 31 of the swing arm 30 on the edge of the magnetron housing 10, and the swing arm 30 is allowed to swing at the peripheral opening 102 of the magnetron housing 10. The first mounting post 112 of the first housing 11 and the second mounting post 122 of the second housing 12 are located outside the swing arm 30 to limit the outward swing amplitude of the swing arm 30. Preferably, the first mounting column 112 of the first housing 11 and the second mounting column 122 of the second housing 12 correspond to the gap between adjacent magnetic elements 40 to avoid the magnetic elements 40, so that the swing arm 30 can bring the magnetic elements 40 to have a larger swing amplitude.

The magnetron housing 10 has a central bore 103, the housing space 101 is located around the central bore 103, and the housing space 101 is isolated from the central bore 103, wherein a mounting shaft 600 can be mounted to the central bore 103 of the magnetron housing 10 by a flange 700.

Further, the flywheel 400 includes a wheel disc 410 and a wheel rim 420, and a flywheel through hole 440 having a wheel cavity 430 and communicating with the wheel cavity 430, the wheel rim 420 integrally extends to the edge of the wheel disc 410 to form the wheel cavity 430 between the wheel rim 420 and the wheel disc 410, and the flywheel through hole 440 is formed at the center of the wheel rim 420. The inner magnetic control device 100 is mounted in the wheel cavity 430 of the flywheel 400, and the wheel ring 420 surrounds the outer side of the peripheral opening 102 of the magnetron housing 10 of the inner magnetic control device 100, the flywheel through hole 440 of the flywheel 400 corresponds to the central through hole 103 of the magnetron housing 10 of the inner magnetic control device 100, wherein the mounting shaft 600 penetrates into the flywheel space 440 of the flywheel 400, so as to assemble the flywheel 400 and the inner magnetic control device 100 and allow the flywheel 400 to rotate relative to the inner magnetic control device 100. Additionally, the mounting shaft 600 may be configured to mount the internal magnetic control device 100 and the flywheel 400 to the fixture rack 200, and the mounting shaft 600 allows the relative positions of the internal magnetic control device 100 and the fixture rack 200 to be fixed and allows the flywheel 400 to rotate relative to the fixture rack 200.

When the driving unit 20 drives the swing arm 30 to swing relative to the magnetron housing 10, the swing arm 30 can drive the magnetic element 40 to swing synchronously and at the same amplitude to change the relative position between the magnetic element 40 and the flywheel 400, so as to adjust the relative position between the magnetic induction line of the inner magnetron device 100 and the flywheel 400, thereby adjusting the load obtained when the flywheel 400 is driven to rotate, and achieving the purpose of controlling the resistance value of the moving device 10000.

Specifically, when the driving unit 20 drives the swing arm 30 to swing outward to a maximum swing position, the relative distance between the magnetic element 40 and the flywheel 400 is adjusted to a design minimum value, at this time, the flywheel 400 cuts the magnetic induction line of the magnetic element 40 when being driven to rotate, and the resistance that the flywheel 400 can obtain is the largest, that is, the resistance value when the user steps on the stepping device 300 to exercise with the exercise apparatus 10000 is the largest. Accordingly, when the swing arm 30 is driven by the driving unit 20 to swing inward to a minimum swing position, the relative distance between the magnetic element 40 and the flywheel 400 is adjusted to a design maximum value, at which the flywheel 400 cuts the magnetic induction line of the magnetic element 40 when being driven to rotate, and the resistance that the flywheel 400 can obtain is minimum, that is, the resistance value when the user steps on the stepping device 300 to exercise with the exercise apparatus 10000 is minimum.

It can be understood that, in the process that the swing arm 30 is driven to swing from the minimum swing position to the maximum swing position by the driving unit 20, the amount of the magnetic induction lines of the magnetic element 40 cut by the flywheel 400 when the flywheel 400 is driven to rotate gradually increases, so that the resistance force that the flywheel 400 can obtain when the flywheel 400 is driven to rotate gradually increases. Accordingly, in the process that the swing arm 30 is driven to swing from the maximum swing position to the minimum swing position by the driving unit 20, the amount of the magnetic induction lines of the magnetic element 40 cut by the flywheel 400 when driven to rotate is gradually reduced, so that the resistance that the flywheel 400 can obtain when driven to rotate is gradually reduced.

With continued reference to fig. 5A and 5B, the driving unit 20 of the internal magnetic control device 100 further includes a driving motor 21, a transmission gear set 22, a driving ring 23, and at least one linkage arm 24. The drive motor 21 is mounted to the first housing 11 and/or the second housing 12 of the magnetron housing 10, and the drive motor 21 is held in the housing space 101 of the magnetron housing 10.

One end of the interlocking arm 24 is rotatably mounted to the drive ring 23, and the other end of the interlocking arm 24 is rotatably mounted to the driven end 32 of the swing arm 30. When the driving motor 21 drives the driving ring 23 to rotate through the transmission gear set 22, the driving ring 23 drives the swing arm 30 to swing through the linkage arm 24, so as to adjust the relative positions of the magnetic element 40 and the flywheel 400.

Specifically, referring to fig. 5A and 5B, when the driving motor 21 drives the driving ring 23 to rotate clockwise through the transmission gear set 22, the driving ring 23 drives the swing arm 30 to swing inward through the linkage arm 24, so as to allow the swing arm 30 to swing from the maximum swing position to the minimum swing position. Accordingly, when the driving motor 21 drives the driving ring 23 to rotate counterclockwise through the transmission gear set 22, the driving ring 23 drives the swing arms 30 to swing outward through the linkage arms 24, so as to allow the swing arms 30 to swing from the minimum swing positions to the maximum swing positions.

It is worth mentioning that the number of the linkage arms 24 of the driving unit 20 corresponds to the number of the swing arms 30. For example, in the specific example of the sports apparatus 10000 of the present invention shown in fig. 5A and 5B, the internal magnetic control device 100 includes two of the swing arms 30, and accordingly, the driving unit 20 includes two of the linkage arms 24, wherein one end of each of the linkage arms 24 is rotatably installed at each of the opposite sides of the driving ring 23, and the other end of each of the linkage arms 24 is installed at the driven end 32 of each of the swing arms 30, so that when the driving motor 21 drives the driving ring 23 to rotate through the transmission gear set 22, the driving ring 23 can drive each of the swing arms 30 to swing through each of the linkage arms 24. It is understood that in the embodiment where the number of the swing arms 30 of the internal magnetic control device 100 is three, the number of the linkage arms 24 of the driving unit 20 is selected to be three.

It is to be noted that the number of gears in the transmission gear set 22 is not limited in the sporting apparatus 10000 of the present invention, for example, in this specific example of the sporting apparatus 10000 shown in fig. 5A and 5B, the number of gears in the transmission gear set 22 is three, which is respectively defined as a first gear 221, a third gear 223, and a second gear 222 engaged with the first gear 221 and the third gear 223, respectively, the first gear 221, the second gear 222, and the third gear 223 are respectively rotatably held in the housing space 101 of the magnetron housing 10, for example, the first gear 221, the second gear 222, and the third gear 223 respectively have a rotating shaft 220, and opposite ends of the rotating shaft 220 of the first gear 221, the second gear 222, and the third gear 223 are respectively rotatably mounted to the first housing 11 and the second housing 12 of the magnetron housing 10, so that the first gear 221, the third gear 222, and the third gear 223 are respectively rotatably held in the housing space 101 of the magnetron housing 10. The first gear 221 is engaged with the worm 211 of the driving motor 21, and the third gear 223 is engaged with the first ring gear 231 of the driving ring 23, so that the power provided by the driving motor 21 can be transmitted to the driving ring 23 through the first gear 221, the second gear 222 and the third gear 223 at a time, so as to drive the swing arm 30 to swing by the driving ring 23 through the linkage arm 24.

It is worth mentioning that the linkage arm 24 and the swing arm 30 are not limited to the sports equipment 10000. For example, in the specific example of the sports apparatus 10000 shown in fig. 5A and 5B, the internal magnetic control device 100 further includes at least one assembly 50, the assembly 50 is mounted to the driven end 32 of the swing arm 30, and the end of the linkage arm 24 is rotatably mounted to the assembly 50.

With continued reference to fig. 5A and 5B, in this specific example of the sporting apparatus 10000 of the present invention, the driving motor 21 of the driving unit 20 is fixedly installed to the first housing 11 of the magnetron housing 10. The first housing 11 has a boss 113, wherein the drive ring 23 is rotatably fitted over the boss 113 of the first housing 11 so that the drive ring 23 can rotate about the central axis when driven. In other words, the drive ring 23, when driven, is able to rotate about the mounting shaft 600 to adjust the relative positions of the magnetic element 40 and the flywheel 400.

With continued reference to fig. 5A and 5B, the driving unit 20 further includes an auxiliary gear 25, wherein the auxiliary gear 25 is rotatably mounted in the housing space 101 of the magnetron housing 10, the driving ring 23 has a row of second ring teeth 232, and the second ring teeth 232 of the driving ring 23 and the auxiliary gear 25 are engaged to prevent the driving ring 23 from tilting when the driving ring 23 is driven, so as to ensure that the driving ring 23 stably and reliably rotates around the central shaft relative to the magnetron housing 10.

With continuing reference to fig. 5A and 5B, the internal magnetic control device 100 further includes a potential control unit 60, the potential control unit 60 includes a circuit board 61, the circuit board 61 is mounted in the housing space 101 of the magnetron housing 10, and the driving motor 21 of the driving unit 20 is connected to the circuit board 61 of the potential control unit 60. Preferably, the circuit board 61 is fixedly mounted to the first housing 11 of the magnetron housing 10, for example, the circuit board 61 may be fixedly mounted to the first housing 11 of the magnetron housing 10 by, but not limited to, screws.

The potential control unit 60 further includes a rotary potentiometer 62, the rotary potentiometer 62 is connected to the circuit board 61, and the rotary potentiometer 62 has a mounting end 621 and a rotating shaft 622, the mounting end 621 of the rotary potentiometer 62 is mounted to the first housing 11, the auxiliary gear 25 is mounted to the rotating shaft 622 of the rotary potentiometer 62, so that the auxiliary gear 25 is rotatably mounted to the housing space 101 of the magnetron housing 10. When the driving motor 21 drives each of the swing arms 30 to swing inward or outward through each of the linkage arms 22 by the rotation of the driving ring 23, the driving ring 23 synchronously drives the auxiliary gear 25 to rotate, and at the same time, the auxiliary gear 25 drives the rotating shaft 622 of the rotary potentiometer 62 to rotate to change the resistance value of the rotary potentiometer 62. It will be appreciated that the resistance of the rotary potentiometer 62 is related to the rotational position of the drive ring 23, and the rotational position of the drive ring 23 determines the swing position of the swing arm 30 and the position of the magnetic element 40, and thus the load on the flywheel 400 when driven to rotate. In other words, the position of the magnetic element 40 of the inner magnetic control device 100 of the exercise apparatus and the load of the flywheel 400 when driven to rotate can be determined by detecting the resistance of the rotary potentiometer 62.
