Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.
Fig. 1 to 12 show an internal magnetic control device 100 according to a preferred embodiment of the present invention, wherein the internal magnetic control device 100 is configured to provide a magnetic field environment, and fig. 13 shows an exercise apparatus to which the internal magnetic control device 100 of the present invention is applied.
It should be noted that the exercise apparatus embodied as an elliptical machine shown in FIG. 13 is exemplary only and is not intended to limit the particular type of exercise apparatus of the present invention. For example, in other examples of the invention, the exercise apparatus may also be a rowing machine, a spinning bike, or the like.
With continued reference to FIG. 13, and with reference to FIG. 1, the exercise apparatus includes an equipment rack 200, a pedaling device 300, and a flywheel 400, wherein the pedaling device 300 is pedably mounted to the equipment rack 200, wherein the flywheel 400 is rotatably mounted to the equipment rack 200 and is drivably connected to the pedaling device 300, and the flywheel 400 surrounds the outer side of the inner magnet control device 100. Preferably, the internal magnet control device 100 is mounted to the fixture rack 200 such that the relative positions of the internal magnet control device 100 and the fixture rack 200 remain unchanged. When the user continuously steps on the stepping device 300 to drive the flywheel 400 to rotate relative to the equipment rack 200 and the inner magnetic control device 100, the flywheel 400 continuously cuts the magnetic induction lines of the inner magnetic control device 100 to obtain a load, so that the user can achieve the purpose of body building.
It can be understood that the load obtained by the flywheel 400 when the flywheel 400 is driven to rotate is related to the amount of the magnetic induction lines of the internal magnetic control device 100 cut by the flywheel 400, wherein the greater the amount of the magnetic induction lines of the internal magnetic control device 100 cut by the flywheel 400 when the flywheel 400 is driven, the greater the load obtained by the flywheel 400, and the harder the user is to step on the stepping device 300, and correspondingly, the less the amount of the magnetic induction lines of the internal magnetic control device 100 cut by the flywheel 400 when the flywheel 400 is driven, the smaller the load obtained by the flywheel 400, and the more labor is saved when the user steps 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, 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 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 equipment, the internal magnetic control device 100 of the invention is configured to adjust the position of the magnetic induction lines relative to the flywheel 400, so 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 cuts the magnetic induction lines when being driven, and conversely, the farther the position of the magnetic induction lines of the internal magnetic control device 100 is from the flywheel 400, the less the flywheel 400 cuts the magnetic induction lines when being driven, so that the resistance value of the users when stepping on the stepping device 300 can be adjusted.
Specifically, with continued reference to fig. 1 to 11B, the internal magnetic control device 100 includes a housing 10, a slider 20, at least one swing arm 30, at least one connecting rod 40, and at least one set of magnetic elements 50.
The housing 10 has a central through hole 101, a housing space 102, a peripheral opening 103, an avoiding space 104 and a slide rail 105, the housing space 102 is located outside the central through hole 101, the peripheral opening 103 is formed on the periphery of the housing 10, the peripheral opening 103 is communicated with the housing space 102, the avoiding space 104 extends from the housing space 102 to the central through hole 101, the slide rail 105 is located in the housing space 102, and the extending direction of the slide rail 105 is consistent with the radial direction of the housing 10, so that the outer end 1051 of the slide rail 105 extends toward the edge of the housing 10, and the inner end 1052 of the slide rail 105 extends toward the avoiding space 104 of the housing 10. Preferably, the slide rail 105 is provided to extend to the escape space 104 of the housing 10.
The housing 10 allows the mounting shaft of the equipment rack 200 to pass through and be retained in the central bore 101 of the housing 10 to fixedly mount the internal magnetic control device 100 to the equipment rack 200, wherein the flywheel 400 surrounds the housing 10 and the peripheral opening 103 of the housing 10 faces the inside of the flywheel 400.
The slider 20 is slidably mounted to the slide rail 105 of the housing 10, and the slider 20 is allowed to slide to the escape space 104 of the housing 10, so that the slider 20 has a larger stroke range. For example, in the specific example of the internal magnet control device 100 shown in fig. 1 to 11B, the stroke of the slider 20 may exceed 12mm, and may even reach 20 mm.
Specifically, referring to fig. 11A and 11B, the slider 20 has a riding groove 21, wherein the slide rail 105 of the housing 10 extends to the riding groove 21 of the slider 20 to allow the slider 20 to ride on the slide rail 105 of the housing 10, so that the slider 20 can reliably slide between the outer end 1051 and the inner end 1052 of the slide rail 105 along the track formed by the slide rail 105 when the slider 20 is driven.
More specifically, with continued reference to fig. 11A and 11B, the slider 20 includes a slider main body 22 and two slider arms 23, and the two slider arms 23 respectively integrally extend outward from one side of the slider main body 22 to form the riding groove 21 between the slider main body 22 and the two slider arms 23, wherein when the slider 20 is mounted on the slide rail 105 of the housing 10, the slide rail 105 extends to the riding groove 21 of the slider 20, so that the slider main body 22 is attached to the top surface of the slide rail 105 and each slider arm 23 is attached to each side surface of the slide rail 105, thereby ensuring that the slider 20 reliably rides on the slide rail 105, and preventing the slider 20 from falling off the slide rail 105 when the slider 20 is driven to slide along the track formed by the slide rail 105.
The swing arm 30 has a pivot end 31 and a driven end 32 corresponding to the pivot end 31, wherein the outer side of the swing arm 30 faces the peripheral opening 103 of the housing 10, a set of magnetic elements 50 is disposed on the outer side of the swing arm 30 to provide a magnetic field environment at the position of the peripheral opening 103 of the housing 10, wherein the pivot end 31 of the swing arm 30 is rotatably mounted on the edge of the housing 10, the driven end 32 of the swing arm 30 is rotatably mounted on one end of the connecting rod 40, and the other end of the connecting rod 40 is rotatably mounted on the slider 20, so that when the slider 20 is driven to slide along the track formed by the slide rails 105 of the housing 10, the slider 20 can apply a force to the driven end 32 of the swing arm 30 through the connecting rod 40 to allow the swing arm 30 to swing relative to the housing 10 around the pivot end 31 of the swing arm 30, thereby swinging the outer side of the swing arm 30 in a direction approaching the peripheral opening 103 of the housing 10 or in a direction departing from the peripheral opening 103 of the housing 10.
Specifically, when the sliding block 20 is driven to slide along the track formed by the sliding rail 105 of the housing 10 from the outer end 1051 to the inner end 1052 of the sliding rail 105, the sliding block 20 can pull the swing arm 30 to swing inward through the connecting rod 40, so that the swing arm 30 drives the magnetic element 50 to move away from the peripheral opening 103 of the housing 10. Accordingly, when the sliding block 20 is driven to slide along the track formed by the sliding rail 105 of the housing 10 from the inner end 1052 to the outer end 1051 of the sliding rail 105, the sliding block 20 can push the swing arm 30 to swing outwards through the connecting rod 40, so that the swing arm 30 drives the magnetic element 50 to move towards the direction close to the peripheral opening 103 of the housing 10.
Preferably, the swing arm 30 extends between the pivot end 31 and the driven end 32 in a curved manner such that the swing arm 30 has an arc shape, such that the shape of the outer side of the swing arm 30 is substantially the same as the shape of the periphery of the housing 10. Preferably, the magnetic element 50 is arc-shaped, and the shape of the inner side of the magnetic element 50 is consistent with the shape of the outer side of the swing arm 30, so as to reliably arrange the magnetic element 50 on the outer side of the swing arm 30.
It should be noted that the manner in which the magnetic element 50 is disposed on the swing arm 30 is not limited in the internal magnetic control device 100 of the present invention, and for example, the magnetic element 50 may be disposed on the outer side of the swing arm 30 by bonding, or the magnetic element 50 may be disposed on the outer side of the swing arm 30 by fitting.
It is also worth mentioning that the number of the magnetic elements 50 in a set of the magnetic elements 50 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. 1 to 11B, the number of the magnetic elements 50 in a set of the magnetic elements 50 is three, and the three magnetic elements are arranged at intervals outside the swing arm 30.
With continuing reference to fig. 1-11B, in this particular example of the internal magnetic control device 100 of the present invention, the internal magnetic control device 100 comprises one sliding block 20, two swing arms 30, two connecting rods 40 and two groups of magnetic elements 50, wherein two of the swing arms 30 are rotatably mounted to the edge of the housing 10 in such a manner that the pivot ends 31 of the two swing arms 30 are adjacent, and the driven ends 32 of the two swing arms 30 respectively extend to positions adjacent to the sliders 20, wherein one end portions of the two connecting rods 40 are rotatably mounted to the driven ends 32 of the two swing arms 30, respectively, the other end portions of the two connecting rods 40 are rotatably mounted to each side portion of the slider 20, respectively, wherein each set of the magnetic elements 50 is respectively disposed at an outer side of each of the swing arms 30.
Referring to fig. 11A and 11B, when the slider 20 is driven to slide along the track formed by the slide rail 105 of the housing 10 from the inner end 1052 to the outer end 1051 of the slide rail 105, the slider 20 pushes each of the swing arms 30 to swing outwards through each of the connecting rods 40 respectively and synchronously, so that each of the swing arms 30 drives each set of the magnetic elements 50 to move towards the peripheral opening 103 of the housing 10, at which time, the distance between one set of the magnetic elements 50 and the flywheel 400 is reduced, so that the amount of magnetic induction lines cutting the inner magnetic control device 100 when the flywheel 400 is driven to rotate is increased to increase the load obtained by the flywheel 400, so that a user is more strenuous in pedaling the pedaling device 300; accordingly, when the slider 20 is driven to slide along the slide rail 105 of the housing 10 from the outer end 1051 to the inner end 1052 of the slide rail 105, the slider 20 respectively and synchronously pulls each of the swing arms 30 to swing inward through each of the connecting rods 40, so that each of the swing arms 30 respectively drives each set of the magnetic elements 50 to move away from the peripheral opening 103 of the housing 10, at this time, the distance between one set of the magnetic elements 50 and the flywheel 400 is increased, so that the amount of magnetic induction lines cutting the inner magnetic control device 100 when the flywheel 400 is driven to rotate is reduced, and the load obtained by the flywheel 400 is reduced, so that a user can more easily step on the stepping device 300.
It can be understood that, when the sliding block 20 slides to the outer end 1051 of the sliding rail 105 of the housing 10, the swing arm 30 minimizes the distance between a set of the magnetic elements 50 and the flywheel 400, and the flywheel 400 is driven to rotate by cutting the magnetic induction lines of the inner magnetic control device 100 by the maximum amount, so that the flywheel 400 has the maximum load, i.e., the maximum resistance of the user when stepping on the stepping device 300. Accordingly, when the slider 20 slides to the inner end 1052 of the slide rail 105 of the housing 10 to allow the slider 20 to enter the escape space 104 of the housing 10, the swing arm 30 maximizes the distance between a set of the magnetic elements 50 and the flywheel 400, and the flywheel 400 is driven to rotate at the same time, the amount of magnetic induction lines cutting the internal magnetic control device 100 is minimized to allow the flywheel 400 to have a minimum load, i.e., a minimum resistance of a user when stepping on the stepping device 300. Therefore, the slide block 20 can have a larger stroke range by providing the escape space 104 in the housing 10, so that the swing arm 30 has a larger swing range, and the load of the flywheel 400 can be adjusted in a larger load range.

With continued reference to fig. 1 to 11B, the internal magnetic control device 100 further includes a potential control unit 90, the potential control unit 90 includes a circuit board 91 and a sliding potentiometer 92, wherein the circuit board 91 is mounted to the bottom case 11 and is held in the housing space 102 of the housing 10, wherein the sliding potentiometer 92 further includes a potentiometer main body 921 and a sliding arm 922 slidably disposed on the potentiometer main body 921, the potentiometer main body 921 is attached to or soldered to the circuit board 91, and the sliding arm 922 is mounted to the slider 20. When the sliding block 20 is driven to move along the sliding rail 105 of the housing 10, the sliding block 20 drives the sliding arm 922 to move relative to the potentiometer main body 921, so as to change the resistance value of the sliding potentiometer 92.
It should be noted that the manner in which the sliding arm 922 of the sliding potentiometer 92 is mounted to the sliding block 20 is not limited in the internal magnetic control device 100 of the present invention, for example, the sliding block 20 may have a mounting groove 25, wherein the sliding arm 922 of the sliding potentiometer 92 extends to and is held in the mounting groove 25 of the sliding block 20, so as to mount the sliding arm 922 of the sliding potentiometer 92 to the sliding block 20.
It will be appreciated that the resistance of the sliding potentiometer 92 is related to the position of the slider 20 on the sliding track 105 of the housing 10, and the position of the slider 20 on the sliding track 105 of the housing 10 determines the position of the magnetic element 50, and thus the load of the flywheel 400 when driven to rotate. In other words, the position of the magnetic element 50 of the internal magnetic control device 100 and the load of the flywheel 400 when driven to rotate can be determined by detecting the resistance of the sliding potentiometer 92.
However, due to the error of the sliding potentiometer 92 itself, the mounting error of the potentiometer main body 921 of the sliding potentiometer 92, and the mounting error of the sliding arm 922, when the internal magnetic control devices 100 of the present invention are produced in a batch, the starting point and the ending point of the resistance value of the sliding potentiometer 92 of a batch of the internal magnetic control devices 100 have an error, and the error range is usually between 0% and 5%, which causes the error range of the starting point and the ending point of the positions of the magnetic elements 50 of a batch of the internal magnetic control devices 100 to be also between 0% and 5%, and finally causes the difference of the magnetic group resistances of a batch of the internal magnetic control devices 100 to reach 10% to 20%, thus resulting in poor consistency of a batch of the internal magnetic control devices 100. Therefore, in order to ensure a batch of resistance values of the internal magnetic control devices 100, after the potentiometer main body 921 of the sliding potentiometer 921 is attached to the circuit board 91 and the sliding arm 922 is mounted to the slider 20, the sliding potentiometer 921 needs to be tested and calibrated.

Alternatively, in other examples of the internal magnetic control device 100 according to the invention, the calibration potentiometer 93 and the sliding potentiometer 92 may be connected in parallel, so that the initial position of the resistance value of the internal magnetic control device 100 can be calibrated by adjusting the calibration potentiometer 93.
Further, the housing 10 has a calibration channel 14, the calibration channel 14 is formed on the housing cover 12, wherein the calibration potentiometer 93 is disposed corresponding to the calibration channel 14, so that the initial position of the resistance value of the internal magnetic control device 100 can be calibrated through the calibration channel 14 of the housing 10 without disassembling the internal magnetic control device 100, thereby greatly improving the efficiency of calibrating the resistance value of the internal magnetic control device 100 and the production efficiency. Specifically, the initial resistance position of the internal magnetic control device 100 can be calibrated by rotating the calibration potentiometer 93 on the outer side of the housing 10 by using a simple tool (e.g., a screwdriver). Preferably, the calibration potentiometer 93 extends to the calibration channel 14 of the housing 10.
Referring to fig. 12, the principle of the calibration potentiometer 93 for calibrating the critical position (e.g., initial resistance position) of the internal magnetic control device 100 is as follows: the sliding potentiometer 92 and the calibration potentiometer 93 are connected in series, with a parameter R1Is the sliding potentiometer 92, parameter R2Is the calibration potentiometer 93, a parameter a is a position where the slider 20 slides the sliding arm 922 to the sliding potentiometer 92 when the slider 20 slides to the outer end 1051 of the sliding rail 105 of the housing 10, a parameter B is a position where the slider 20 slides the sliding arm 922 to the sliding potentiometer 91 when the slider 20 slides to the inner end 1052 of the sliding rail 105 of the housing 10, and a parameter R1A is the distance between point A and the slider 922, and R is the parameter1B is the distance between point B and the sliding arm 922, and R is the parameter1A and the parameter R1B is dynamic, changing as the position of the wiper 922 sliding on the wiper potentiometer 92 changes, a parameter V0With the value of R1A and R1The variation of the partial pressure value of B varies.
For the internal magnetic control device 100 not provided with the calibration potentiometer 93, the above parameters satisfy the condition:
when the internal magnetic control device 100 of the present invention is mass-produced, V is a factor of the error of the slide volume 92 itself, the mounting error of the volume 921 of the slide volume 92, and the mounting error of the slide arm 9220Error in the values of (c) results in poor consistency of a batch of the internal magnetic control devices 100.
For the internal magnetic control device 100 to which the calibration potentiometer 93 is provided, the above parameters satisfy the condition:
i.e. V0’＝Δ+V0Wherein the resistance of the calibration potentiometer 93 is adjustable, for example by the housing 10The calibration channel 14 can adjust the resistance of the calibration potentiometer 93, i.e., adjust the value of the parameter Δ, by rotating the calibration potentiometer 93 at the outer side of the housing 10, thereby conveniently calibrating the initial position of the resistance of the internal magnetic control devices 100 and ensuring the consistency of a batch of internal magnetic control devices 100.
