Fig. 1 shows an exercise apparatus according to a preferred embodiment of the present invention, fig. 2 to 8B show an internal magnetic control device 100 according to a preferred embodiment of the present invention, the internal magnetic control device 100 being used for providing a magnetic field environment, wherein the exercise apparatus is applied with the internal magnetic control device 100 according to the present invention, and fig. 9A to 9E show an assembling process of the internal magnetic control device 100.
It should be noted that the exercise apparatus embodied as an elliptical machine shown in FIG. 1 is merely exemplary and is not intended to limit the particular type of exercise apparatus of the present invention. For example, in other examples of the utility model, the exercise apparatus may also be a rowing machine, a spinning bike, or the like.
Referring to fig. 1 and 2, the exercise apparatus of the present invention comprises the internal magnet control device 100, an apparatus frame 200, a pedaling device 300, and a flywheel 400, wherein the internal magnet control device 100 is mounted to the apparatus frame 200, wherein the pedaling device 300 is pedably mounted to the apparatus frame 200, wherein the flywheel 400 is rotatably mounted to the apparatus frame 200 and is drivably connected to the pedaling device 300, and the flywheel 400 is disposed around the outside of the internal magnet control device 100. 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, 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 body building equipment.
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 meet different requirements of users on the load of the flywheel 400 of the exercise apparatus, the internal magnetic control device 100 of the present invention is configured to adjust the relative positions of the magnetic induction lines and the flywheel 400, so that the closer the positions of the magnetic induction lines of the internal magnetic control device 100 are to the flywheel 400, the more the flywheel 400 cuts the magnetic induction lines of the internal magnetic control device 100 when being driven to rotate, and correspondingly, the farther the positions of the magnetic induction lines of the internal magnetic control device 100 are from the flywheel 400, the less the flywheel 400 cuts the magnetic induction lines of the internal magnetic control device 100 when being driven to rotate. Therefore, by adjusting the relative positions of the magnetic induction lines of the inner magnet control device 100 and the flywheel 400, the resistance value of the user when stepping on the stepping device 300 can be adjusted.
Specifically, referring to fig. 2 to 8B, the inner magnetron apparatus 100 includes a magnetron housing 10, a driving module 20, two swing arms 30 and two sets of magnetic elements 40, wherein the magnetron housing 10 has a housing space 101 and a peripheral opening 102 communicating with the housing space 101, wherein the driving module 20 is disposed in the housing space 101 of the magnetron housing 10 for providing driving force, wherein each of the swing arms 30 has a pivoting end 31 and a driven end 32 corresponding to the pivoting end 31, the pivoting ends 31 of the swing arms 30 are rotatably mounted to the magnetron housing 10, the driven ends 32 of the swing arms 30 are drivably connected to the driving module 20, and the two swing arms 30 are retained in the peripheral opening 102 of the magnetron housing 10 in a mutually symmetrical manner, wherein each set of magnetic elements 40 is disposed on each of the swing arms 30, to allow each set of magnetic elements 40 to provide a magnetic field environment at the peripheral opening 102 of the magnetron housing 10. The flywheel 400 can surround 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 400, 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 each set of the magnetic elements 40 of the internal magnetic control device 100 to obtain a load.
Preferably, the outer side of each swing arm 30 faces the peripheral opening 102 of the magnetron housing 10, and each set of the magnetic elements 40 is respectively disposed at the outer side of each swing arm 30, so that each set of the magnetic elements 40 can be directly exposed to the peripheral opening 102 of the magnetron housing 10.
It should be noted that the way in which each set of the magnetic elements 40 is disposed on each swing arm 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 set of the magnetic elements 40 may be disposed 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 set of the magnetic elements 40 may be installed on each of the swing arms 30 by being embedded.
It should be noted that the number of the magnetic elements 40 in each set of the magnetic elements 40 is not limited in the internal magnetic control device 100 of the present invention. For example, in the specific example of the internal magnetic control device 100 shown in fig. 2 to 8B, the number of the magnetic elements 40 in each set of the magnetic elements 40 is three, and the three magnetic elements are arranged at intervals outside the swing arm 30.
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 set of magnetic elements 40 is arc-shaped, and the shape of the inner side of the set of magnetic elements 40 is consistent with the shape of the outer side of the swing arm 30, so as to reliably arrange the set of magnetic elements 40 on the outer side of the swing arm 30.
Referring to fig. 3A to 4B, the magnetron housing 10 includes a disk-shaped first housing 11 and a disk-shaped second housing 12, the first housing 11 is provided with a first ring 111, and the second housing 12 is provided with a second ring 121, wherein the first housing 11 and the second housing 12 are mutually mounted 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 sides of the first ring 111 and the second ring 121, and form the peripheral opening 102 on the outer sides of the first ring 111 and the second ring 121.
Further, a plurality of first mounting posts 112 are provided on the edge of the first housing 11, a plurality of second mounting posts 122 are provided on the edge of the second housing 12, and each of the first mounting posts 112 of the first housing 111 and each of the second mounting posts 122 of the second housing 12 are mounted and supported to 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 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.
Opposite sides of the pivot end 31 of the swing arm 30 are rotatably mounted to the edge of the first housing 11 and the edge of the second housing 12 to rotatably mount the pivot end 31 of the swing arm 30 to 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, 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 located outside the swing arm 30 to limit the outward swing amplitude 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 of two adjacent magnetic elements 40 in a set of magnetic elements 40 to avoid the magnetic elements 40.
Referring to fig. 3A-4B, the magnetron housing 10 further has a central through hole 103, and the housing space 101 is located around the central through hole 103, wherein the mounting shaft of the fixture rack 200 can be mounted in the central through hole 103 of the magnetron housing 10 to fixedly mount the internal magnetic control device 100 to the fixture rack 200.
When a user steps on the stepping device 300 of the exercise apparatus to drive the flywheel 400 to rotate relative to the internal magnetic control device 100, the flywheel 400 can cut the magnetic induction lines of each set of the magnetic elements 40 of the internal magnetic control device 100 to obtain a load, so that the user can achieve the purpose of exercise through the exercise apparatus.
When the driving module 20 drives each swing arm 30 to swing relative to the magnetron housing 10, each set of swing arms 30 can drive each set of magnetic elements 40 to swing synchronously, so as to change the relative distance between each set of magnetic elements 40 and the flywheel 400, and thus adjust the relative distance between the magnetic induction line of the internal magnetic control device 100 and the flywheel 400, thereby adjusting the load obtained when the flywheel 400 is driven to rotate, and further adjusting the resistance value of a user when the user steps on the stepping device 300.
For example, referring to fig. 8A, when the driving module 20 drives each swing arm 30 to swing outward to a maximum swing position, the relative distance between each set of the magnetic elements 40 and the flywheel 400 is adjusted to a design minimum, at this time, the flywheel 400 cuts the magnetic induction lines of each set of the magnetic elements 40 by the largest amount when being driven to rotate, and the resistance that can be obtained by the flywheel 400 is the largest. Accordingly, referring to fig. 8B, when the driving module 20 drives each swing arm 30 to swing inward to a minimum swing position, the relative distance between each set of the magnetic elements 40 and the flywheel 400 is adjusted to a design maximum value, at which the flywheel 400 cuts the magnetic induction lines of each set of the magnetic elements 40 by the minimum amount when being driven to rotate, and the resistance that can be obtained by the flywheel 400 is the minimum.
It can be understood that, in the process that the driving module 20 drives each swing arm 30 to swing from the minimum swing position to the maximum swing position, the amount of the magnetic induction lines of each group of the 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 the flywheel 400 is driven to rotate gradually increases. Accordingly, in the process that the driving module 20 drives each swing arm 30 to swing from the maximum swing position to the minimum swing position, the amount of the magnetic induction lines of each group of the magnetic elements 40 cut by the flywheel 400 when the flywheel 400 is driven to rotate is gradually reduced, so that the resistance that the flywheel 400 can obtain when the flywheel 400 is driven to rotate is gradually reduced.
Referring to fig. 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 connected to the driving mechanism 21 in a driving manner, the other end of each linkage mechanism 22 is respectively rotatably mounted on the driven end 32 of each swing arm 30, wherein the two linkage mechanisms 22 have an overlapping portion in the height direction, in such a manner that when the driving force provided by the driving mechanism 21 is transmitted to each linkage mechanism 22, each linkage mechanism 22 can apply a large angle to each swing arm 30 to drive each swing arm 30 to respectively drive each set of magnetic elements 40 to swing relative to the magnetron housing 10, and thus: on one hand, the inner magnetic control device 100 of the present invention can reduce the requirement for the driving force of the driving mechanism 21, thereby being beneficial to reducing the cost of the inner magnetic control device 100, and on the other hand, the inner magnetic control device 100 of the present invention can smoothly drive each swing arm 30 to swing in a larger range, thereby being beneficial to improving the reliability of the inner magnetic control device 100.
It should be noted that the manner in which the linkage 22 is rotatably mounted to 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 an end of the linkage 22 is rotatably mounted on the assemblies 50, the assemblies 50 are mounted on the driven ends 32 of the swing arms 30, and the end of the linkage 22 is rotatably mounted on the driven ends 32 of the swing arms 30.
For easy understanding and description, referring to fig. 8A and 8B, two swing arms 30 of the internal magnetic control device 100 are defined as a left side swing arm 30a and a right side swing arm 30B, and correspondingly, two linkage mechanisms 22 of the driving module 20 of the internal magnetic control device 100 are defined as a left side linkage mechanism 22a and a right side linkage mechanism 22B. One end of the left linkage mechanism 22a is rotatably mounted to the driven end 32 of the left swing arm 30a, the other end of the left linkage mechanism 22a extends in a direction toward the right swing arm 30b and is drivably connected to the driving mechanism 21, accordingly, one end of the right linkage mechanism 22b is rotatably mounted to the driven end 32 of the right swing arm 30b, and the other end of the right linkage mechanism 22b extends in a direction toward the left swing arm 30a and is drivably connected to the driving mechanism 21, wherein the left linkage mechanism 22a and the right linkage mechanism 22b have an overlapping portion in a height direction. For example, in the specific example of the internal magnetic control device 100 shown in fig. 2 to 8B, the right linkage 22B is located above the left linkage 22 a. Of course, it is understood that in other alternative examples of the internal magnetic control device 100 of the present invention, the right linkage 22b may be located at a lower portion of the left linkage 22 a.
In other words, the projection of the left interlocking mechanism 22a on the magnetron housing 10 and the projection of the right interlocking mechanism 22b on the magnetron housing 10 have an overlapping portion and are in an "X" shape, in this way, the angle formed by the extending direction of the line between the center of the pivoting end 31 and the center of the driven end 32 of the left swing arm 30a and the extending direction of the left interlocking mechanism 22a is a large angle, to allow the left side link mechanism 22a to apply a force to the left side swing arm 30a at a large angle, and, accordingly, the extending direction of the connecting line between the center of the pivoting end 31 and the center of the driven end 32 of the right swing arm 30b and the extending direction of the right interlocking mechanism 22b form a large angle, to allow the right side interlocking mechanism 22b to apply a force to the right side swing arm 30b at a large angle.
When the driving mechanism 21 outputs power in one direction, the driving mechanism 21 can drive the left linkage mechanism 22a to move toward a 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 and to swing the left swing arm 30a inward, and at the same time, the driving mechanism 21 can drive the right linkage mechanism 22b to move toward a 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 and to swing the right swing arm 30b inward. Accordingly, when the driving mechanism 21 outputs power in the reverse direction, the driving mechanism 21 can drive the left linkage mechanism 22a to move in a direction 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 and swing the left swing arm 30a outwards, and at the same time, the driving mechanism 21 can drive the right linkage mechanism 22b to move in a direction 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 and swing the right swing arm 30b outwards.
Preferably, with the structure of the inner magnetic control apparatus 100 of the present invention, the left linkage mechanism 22a can keep applying a large angle to the left swing arm 30a no matter when the left linkage mechanism 22a pulls the left swing arm 30a to swing from the maximum swing position to the minimum swing position, or when the left linkage mechanism 22a pushes the left swing arm 30a to swing from the minimum swing position to the maximum swing position; accordingly, the right side interlocking mechanism 22b can keep applying a large angle to the right side swing arm 30b, regardless of whether the right side interlocking mechanism 22b pulls the right side swing arm 30b to swing from the maximum swing position to the minimum swing position, or the right side swing mechanism 22b pushes the right side swing arm 30b to swing from the minimum swing position to the maximum swing position.

In other words, in the internal magnetic control device 100 of the present invention, the driving module 20 can be installed in the housing space 101 of the magnetron housing 10 as a separate module, in such a way that the same driving module 20 can be adapted to different magnetron housings 10, for example, the same driving module 20 can be adapted to magnetron housings 10 with different sizes, so as to obtain the internal magnetic control device 100 with corresponding specifications to meet the use requirements of different fitness equipments.

For example, the first housing 233 and the second housing 234 may be mounted to each other by screws, or the first housing 233 and the second housing 234 may be mounted to each other by a combination of screws and nuts, or the first housing 233 and the second housing 234 may be snap-fitted to each other.
With continued reference to fig. 5A-7, the drive mechanism 21 further includes a drive motor 211 and a gear assembly 212. The driving motor 211 is fixedly installed in the housing space 231 of the driving housing 23, and 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 at opposite sides of the driving motor 211.

When the driving motor 211 outputs power in a manner that the output shaft 2111 of the driving motor 211 rotates, power can be sequentially transmitted to each of the power output gears 2123 through the driven gear 2121 and the transmission gear 2122 to drive each of the power output gears 2123 to synchronously and reversely rotate, at this time, one of the power output gears 2123 and the left side interlocking mechanism 22a can be mutually matched to drive the left side swing arm 30a to swing, the other of the power output gears 2123 and the right side interlocking mechanism 22b can be mutually matched to drive the right side swing arm 30b to swing, and a swing direction and a swing amplitude of the left side swing arm 30a are consistent with a swing direction and a swing amplitude of the right side swing arm 30 b.
Preferably, there is a gap between the two linkages 22 to avoid friction between the two linkages 22, so that: on one hand, the driving mechanism 21 can smoothly drive each swing arm 30 to swing through each linkage mechanism 22; on the other hand, the two interlocking mechanisms 22 do not generate friction, thereby avoiding noise generation and avoiding abrasion of the interlocking mechanisms 22.
