Description

Torsion detection flange, resistance-adjustable rotating wheel, fitness equipment and torsion detection method thereof
Technical Field
The invention relates to the field of fitness equipment, in particular to a torsion detection flange, a resistance-adjustable rotating wheel, fitness equipment and a torsion detection method thereof.
Background
In recent years, the life rhythm and the work rhythm of people are faster and faster, and a few people are in a sub-health state because of lack of exercise for a long time, and more people are aware of the importance of exercise and fitness, and add into a fitness line. Indoor body-building equipment such as running machines, elliptical machines, exercise bicycles, rowing machines and the like can meet the requirement that exercise enthusiasts can easily exercise after working, and become the first choice of the exercise enthusiasts.
The quality of the body-building equipment on the market is endlessly layered, the functions are more and more abundant, the quality detection department judges the quality grade of the body-building equipment more and more strictly in order to ensure the rights of consumers, and one important factor for evaluating the quality grade of the body-building equipment is the error amount between the actual exercise power and the calibrated exercise power of the body-building equipment. Specifically, the greater the difference between the actual power of the user and the calibrated power of the exercise machine, the lower the quality level of the exercise machine, and the lesser the difference between the actual power of the user and the calibrated power of the exercise machine, the higher the quality level of the exercise machine.
Taking elliptical machines as an example, before leaving a factory, staff in the factory can conduct experiments and calculation on one elliptical machine to obtain the relation among the resistance level of a flywheel of the elliptical machine, the position and the rotating speed of a resistance adjusting wheel of the elliptical machine corresponding to each resistance level and corresponding calibration power, and then the relation among the resistance levels of all elliptical machines in the batch, the position and the rotating speed of the resistance adjusting wheel of the elliptical machine corresponding to each resistance level and the corresponding calibration power is set according to the test result of the elliptical machine. That is, if the user moves on different elliptical machines shipped from the same batch, the resistance adjusting wheel of the elliptical machine is adjusted to a preset position when the user selects the same resistance level, and the movement power of the user displayed by the elliptical machine is identical when the user moves at the same rotation speed.
However, in practice, since there will be some differences in the internal parts of each elliptical machine, there will be some deviation in the assembly process, and therefore, even if the user selects the same resistance level on different elliptical machines, the actual resistance experienced by the user will not be the same, and even if the user selects the same resistance level and moves on different elliptical machines at the same rotational speed, the actual power of the user will not be the same. In other words, there must be a difference between the nominal power and the actual power through the existing elliptical machines. That is, the existing elliptical machines are unable to detect the actual power of the user.

Specifically, referring to fig. 10, the apparatus body 200 includes a supporting frame 210, a driving wheel 220, two driving members 230, and a driving belt 240, wherein the driving wheel 220 is rotatably installed on the supporting frame 210, the driving members 230 are operatively installed at both sides of the driving wheel 220, and the driving wheel 220 is connected to the resistance-adjustable rotating wheel 100 through the driving belt 240. In the process that the user drives the driving wheel 220 to rotate relative to the supporting frame 210 through the driving piece 230, the driving wheel 220 drives the driving belt 240 and the resistance-adjustable rotating wheel 100 to rotate. The rotating wheel 100 with adjustable resistance can detect the resistance overcome by the user in the process of operating the driving member 230 to drive the rotating wheel 100 with adjustable resistance, so as to obtain the actual power of the user.
It should be noted that the specific embodiment of the driving member 230 is not limited, and the driving member 230 allows the user to drive by means of foot, pedal, foot, hand-pulling, etc. Also, the specific embodiment of the apparatus body 200 is not limited, and the apparatus body 200 may be implemented as an elliptical machine, a spinning, a rowing machine, or an exercise apparatus known to those skilled in the art. Moreover, it should be understood by those skilled in the art that the particular implementation of the exercise apparatus body 200 disclosed in the text and drawings of the specification is by way of example only and is not intended to limit the scope or content of the exercise apparatus 100 of the present invention.
Referring to fig. 8 and 9, the drag-adjustable rotary wheel 100 includes an inner magnetic drag adjusting device 110, a flywheel 120, a metal spacer 130, a fixing base 140, an assembly shaft 150, and a torsion detecting flange 160, wherein the inner magnetic drag adjusting device 110 has a magnetic surface 1101 and an assembly channel 1102, and the flywheel 120 has a magnetic surface 1201, an accommodating space 1202, and an installation channel 1203. Both ends of the fitting shaft 150 are mounted to the fixing base 140, and the fitting shaft 150 is held in the fitting passage 1102 of the inner magnetron resistance adjustment device 110 and the mounting passage 1203 of the flywheel 120, the flywheel 120 is held outside the inner magnetron resistance adjustment device 110 in such a manner that the magnetic surface 1201 corresponds to the magnetic surface 1101 of the inner magnetron resistance adjustment device 110, and the inner magnetron resistance adjustment device 110 is held in the accommodation space 1202 of the flywheel 120. The metal spacer 130 is held between the flywheel 120 and the inner magnetron resistance adjustment device 110 so as to be attached to the magnetic surface 1201 of the flywheel 120. The fixing base 140 is fixed on the ground or the apparatus body 200, and the torsion detecting flange 160 is connected to the inner magnetic resistance adjusting device 110 and the assembly shaft 150, respectively. The belt 240 of the apparatus body 200 is connected to the flywheel 120 and the driving wheel 240 of the resistance-adjustable rotary wheel 100.
It should be noted that the specific embodiments of the inner magnetic resistance adjusting device 110 and the flywheel 120 are not limited, for example, but not limited to, the inner magnetic resistance adjusting device 110 is provided with a plurality of magnetic blocks, the magnetic surface 1101 is formed on the outer surface of the magnetic blocks, the flywheel 120 is made of metal material, and the magnetic surface 1201 is formed on the inner surface of the flywheel 120.
In the process of using the exercise apparatus, the user needs to overcome the resistance of the flywheel 120, so as to drive the driving wheel 220 and the flywheel 120 to rotate relative to the internal magnetic resistance adjusting device 110 by using the driving member 230 of the apparatus body 200. And during the rotation of the flywheel 120 relative to the inner magnetic resistance adjustment device 110, the inner magnetic resistance adjustment device 110 generates a movement trend following the rotation of the flywheel 120, but the inner magnetic resistance adjustment device 110 is fixed by the resistance seat 140 and the assembly shaft 150 to remain relatively stationary. That is, the torsion detecting flange 160 detects the torsion force of the inner magnetic control resistance adjusting device 110 of the resistance-adjustable rotating wheel 100 in real time, so as to detect the resistance force of the flywheel 120, and further detect the resistance force overcome by the user, so as to calculate the actual power of the user.
Specifically, an external magnetic field is formed between the magnetic surface 1201 of the flywheel 120 and the magnetic surface 101 of the magnetic block of the inner magnetic resistance adjusting device 110, the metal spacer 130 follows the flywheel 120 when the flywheel 120 is driven to rotate relative to the inner magnetic resistance adjusting device 110, and when the metal spacer 130 passes the left edge of the magnetic block of the inner magnetic resistance adjusting device 110, the magnetic field strength sensed by the metal spacer 130 increases, so that a counter-clockwise eddy current is generated, the eddy current generates an internal magnetic field, and the direction of the internal magnetic field is opposite to the direction of the external magnetic field, so that magnetic resistance is generated. When the magnetic surface 101 of the magnetic block of the inner magnetic resistance adjusting device 110 approaches the magnetic surface 1201 of the flywheel 120, the magnetic resistance increases, and the resistance of the flywheel 120 when rotating increases, that is, the torsion of the inner magnetic resistance adjusting device 110 increases, and the resistance overcome by the user increases. When the magnetic surface 101 of the magnet is far away from the magnetic surface 1201 of the flywheel 120, the magnetic resistance is reduced, and the resistance of the flywheel 120 when rotating is reduced, that is, the torsion of the inner magnetic resistance adjusting device 110 is reduced, and the resistance overcome by the user is reduced.

The shaft body 151 of the fitting shaft 150 is held in the fitting passage 1102 of the inner magnetron resistance adjustment device 110 and the mounting passage 1203 of the flywheel 120. The shaft body 151 is fixed to the fixing base 140 at both ends, the inner assembly portion 161 is mounted to the shaft body 151 of the assembly shaft 150 such that the limit groove 1612 corresponds to the assembly shaft 150, and the torque detection flange 160 is not rotatable with respect to the assembly shaft 150 after the limit portion 152 is held in the limit groove 1612. Alternatively, the torsion detecting flange 160 may be further mounted to the mounting shaft 150 by welding, screw connection, bolting, or the like.

Optionally, the torque force detecting flange 160 may also be fixed to the inner magnetic resistance adjusting device 110 by welding or the like.
It should be noted that the specific embodiments of the torsion detecting flange 160, the assembly shaft 150 and the inner magnetic resistance adjusting device 110 are merely examples, and should not be construed as limiting the contents and scope of the torsion detecting flange 160, the resistance-adjustable rotating wheel 100 and the exercise apparatus 1000.
When the flywheel 120 is driven to rotate relative to the inner magnetron resistance adjustment device 110, the inner magnetron resistance adjustment device 110 generates a movement tendency to follow the movement of the flywheel 120, and at this time, a relative movement tendency is generated between the inner fitting portion 161 fixed to the inner magnetron resistance adjustment device 110 and the outer fitting portion 162 fixed to the fitting shaft 150, but the connecting bridge 163 is subjected to a torsion force. At this time, the detecting element 164 can detect the torsion force applied to the connecting bridge 163, that is, obtain the torsion force applied to the inner magnetic resistance adjusting device 110, so as to calculate the actual power of the user when using the exercise apparatus 1000.
Specifically, the fixture body 200 further includes the console 250 and the display 260, wherein the display 260 is communicatively connected to the console 250, and the console 250 is communicatively connected to the inner magnetron resistance adjustment device 110, the flywheel 120, and the torsion detection flange 160 of the resistance-adjustable rotating wheel 100. The console 250 can obtain the operation state of the flywheel 120, the operation state of the internal magnetic resistance regulator 110, and the operation data such as the detection data of the torsion detection flange 160, and process and calculate the operation data of the apparatus main body 200 to obtain movement data of the user during the exercise, where the movement data includes, but is not limited to, movement speed, movement power, consumed heat, movement time, etc. The display 260 displays the movement data generated by the console 250 to facilitate the user to grasp the movement status in real time.
Further, the display 260 allows the control command to be selected or input, the console 250 sends the control command to the internal magnetic resistance adjustment device 110, and the internal magnetic resistance adjustment device 110 adjusts the distance between the magnetic surfaces 1101 of the first and second magnetic shoes 110 and 120 and the magnetic surface 1201 of the flywheel 120 based on the actual power of the user and the calibration power of the exercise apparatus 100, so as to further control the resistance to which the flywheel 120 is subjected, so as to ensure that the actual power of the user and the calibration power of the exercise apparatus 100 are consistent.
For example, when the user uses the exercise apparatus 1000, the user selects the level control command to be "level 1" through the apparatus body 200, and after driving the apparatus body 200 and the flywheel 120, the user detects that the rotational speed of the flywheel 120 is "n" by a rotational speed sensor of the inner magnetic resistance adjustment device 110, and the torque force received by the inner magnetic resistance adjustment device 110 and detected by the torque force detection flange 160 is "F". At this time, the console 250 obtains the corresponding calibration power "pcrop" of the exercise apparatus 1000 according to the level command "level 1" and the rotation speed "n". Meanwhile, the console 250 calculates the actual power of the user as "PHOT" according to the rotational speed "n" and the torque force "F".
Further, the console 250 compares the user's actual power "PHEADER" to the nominal power "PHEADER" of the exercise apparatus 1000. If the actual power "phit" of the user is greater than the calibration power "phit" of the exercise apparatus 1000, the console 250 controls the distance between the magnetic attraction surface 1101 of the inner magnetic resistance adjusting device 110 and the magnetic surface 1201 of the flywheel 120 to increase, and the torque detected by the torque detecting flange 160 to decrease. Until the actual power "pti" of the user, which is obtained based on the detection result of the torsion detection flange 160, is equal to the calibration power "pcrop" of the exercise apparatus 1000, then the magnet of the inner magnetic resistance adjustment device 110 is maintained at the position at this time to ensure that the actual power "pti" of the user is equal to the calibration power "pcrop" of the exercise apparatus 1000.
If the console 250 compares the actual power "phide" of the user with the calibration power "phide" of the exercise apparatus 1000, the console 250 controls the distance between the magnetic attraction surface 1101 of the inner magnetic resistance adjustment device 110 and the magnetic surface 1201 of the flywheel 120 to decrease, and the torque detected by the torque detection flange 160 to increase. Until the actual power "phide" of the user, which is obtained based on the detection result of the torsion detection flange 160, is equal to the calibration power "phide" of the exercise machine 1000, then the magnet of the inner magnetic resistance adjustment device 110 is kept at the position at this time, and the magnet of the inner magnetic resistance adjustment device 110 is kept at the position at this time, so as to ensure that the actual power "phide" of the user is equal to the calibration power "phide" of the exercise machine 1000. That is, after the user selects the exercise level, the exercise machine 1000 adjusts the amount of resistance the user receives according to the difference between the nominal power and the actual power of the user, so as to ensure that the actual power of the user and the nominal power of the exercise machine 1000 are always consistent.
