Description

Torsion detection flange, resistance-adjustable rotating wheel, adjusting method of torsion detection flange and movement equipment

Technical Field

The invention relates to the field of sports equipment, in particular to a torsion detection flange, a resistance-adjustable rotating wheel, an adjusting method thereof and sports equipment.

Background

With the importance of physical health, sports apparatuses are increasingly favored by consumers, and various sports apparatuses in the market are also layered endlessly, especially indoor sports apparatuses such as running machines, spinning, elliptical machines, rowing machines and the like, are popular with consumers in gymnasiums as well as in many home sports.

Most sports apparatuses in the market can detect the movement data of a user in the use process, such as movement speed, movement power, consumption heat, movement time and the like, and timely feed back the movement data to a user interface, so that the user can conveniently check in real time, and further the movement condition can be mastered in real time. Moreover, for quality assessment of sports equipment, accuracy of the sports data directly determines the quality level of the sports equipment, wherein the error between the actual sports power and the calibrated sports power is an important factor for assessing the quality level of the sports equipment.

Taking an elliptical machine as an example for explanation, the elliptical machine comprises a machine body and a resistance adjusting wheel, wherein the machine body comprises a machine body support, a driving wheel, two operating parts, a driving belt and a control console, the driving wheel, the two operating parts, the driving belt and the control console are arranged on the machine body support, and 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 rotation speed and rotation speed sensor 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 magnet 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 level instructions through a console of the elliptical machine so as to obtain different resistance feelings.

In the existing elliptical machine, different resistance level instructions correspond to different preset positions of the magnetic blocks of the resistance adjusting mechanism, the preset positions of the magnetic blocks of the resistance adjusting mechanism corresponding to each resistance level instruction are fixed positions, namely, the distance between the magnetic blocks of the resistance adjusting mechanism corresponding to each resistance level instruction and the metal flywheel is fixed distance. When the elliptical machine is used by a user, the resistance grade instruction, such as 2-gear, is selected through the display screen of the control console, the control module of the resistance regulating mechanism receives the resistance grade instruction and judges whether the position of the magnetic block of the resistance regulating mechanism is the preset position corresponding to the 2-gear at the moment, if not, the magnetic block of the resistance regulating mechanism is regulated to the preset position corresponding to the 2-gear.

After the user selects the resistance grade instruction, the operating part is driven, 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 obtains the rotating speed of the metal flywheel.

And each elliptical machine is preset with the relation between the resistance level, the rotating speed and the calibrated power before leaving the factory. Specifically, before the elliptical machines leave the factory, one elliptical machine is tested, then the corresponding relation between the resistance level, the rotating speed and the calibrated power is obtained, and then the corresponding relation is applied to all elliptical machines leaving the factory. Thus, after the user selects the resistance level instruction, the resistance adjusting mechanism is adjusted to the preset position corresponding to the resistance level instruction, the user drives the elliptical machine to rotate, the elliptical machine obtains the calibration power at the moment according to the resistance level, the rotating speed and the corresponding relation between the resistance level, 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 control console.

However, since there may be a difference in the assembling process of each elliptical machine before shipment or a difference between the same parts, various uncertain factors cause a certain difference between different elliptical machines. For example, when the magnetic blocks of the resistance adjusting mechanisms of different elliptical machines are positioned at the same preset positions, the resistance generated by users 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 nd gear", it is possible that a distance between the magnetic block of the resistance adjusting mechanism of one elliptical machine and the metal flywheel is 8 mm, and a distance between the magnetic block of the other elliptical machine and the resistance adjusting mechanism is 7 mm. However, when the user exercises at the same rotation speed and the same resistance level on the two elliptical machines having the difference, the power displayed through the console is the same nominal power. However, the actual power of the user on the two elliptical machines with the difference is not the same. That is, there must be 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 existing power value presented to the user by the 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, the higher the quality grade of the elliptical machine, the larger the difference between the actual power and the calibrated power of the user, and the lower the quality grade of the elliptical machine. Therefore, how to reduce the difference between the actual power and the calibration power of the user becomes a difficult problem that needs to be overcome by many sports equipment manufacturers.

Referring to fig. 3, in this specific embodiment of the drag force adjustable rotary wheel 1000 according to the present invention, the drag force adjusting device 100 includes a first magnetic shoe 110, a second magnetic shoe 120, a rotary member 130, and a base plate 140, wherein the first magnetic shoe 110 and the second magnetic shoe 120 have the magnetic force surface 101, respectively. The rotating member 130 is rotatably mounted to the base plate 140, and the first and second magnetic shoes 110 and 120 are movably held at both sides of the rotating member 130.

The rotating wheel 200 is made of a metal material, that is, the magnetically conductive surface 101 of the rotating wheel 200 is a metal surface, and the rotating wheel 200 is rotatably held on the outer sides of the first magnetic shoe 110 and the second magnetic shoe 120 in such a manner that the magnetically conductive surface 201 corresponds to the magnetic surfaces 101 of the first magnetic shoe 110 and the second magnetic shoe 120.

The specific processing manner of the data by the exercise apparatus 10000 is not limited, and should not be construed as limiting the content and scope of the drag-adjustable rotary wheel 100 and the adjusting method thereof and the exercise apparatus 1000 according to the present invention.

In a specific embodiment of the present invention, the apparatus body 2000 includes a support frame 2010, a driving wheel 2020, two driving members 2030 and a driving belt 2040, wherein the driving wheel 2020 is rotatably mounted on the support frame 2010, the driving members 2030 are operatively mounted on both sides of the driving wheel 2020, and the driving wheel 2020 is connected to the rotating wheel 200 of the resistance-adjustable rotating wheel 1000 through the driving belt 2040.

Referring to fig. 11 to 15B of the drawings, an exercise apparatus 10000A according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the exercise apparatus 10000A includes an internal magnetic control device 100A, a tool holder 200A, a stepping device 300A, a flywheel 400A, and a torsion detecting device 500A.

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

It is worth mentioning that the sports apparatus 10000A shown in fig. 11 implemented as an elliptical machine is only exemplary, and is not limited to the specific type of the sports apparatus 10000A of the present invention. For example, in other examples of the invention, the sports apparatus 10000A may be a rowing machine, a spinning, or the like. It is understood that the exercise apparatus 10000A may be provided without the stepping device 300A, which can achieve the exercise purpose through the exercise apparatus 10000A as long as the user is allowed to drive the flywheel 400A to rotate.

It may be appreciated that the sports apparatus 10000A has a fixed calibration power, and the actual power of the user when the user exercises through the sports apparatus 10000A may be different from the calibration power of the sports apparatus 10000A due to the assembly process of the sports apparatus 10000A, the parts error, and the like, and the present invention provides the torsion detection device 500A to detect the torsion of the internal magnetic control device 100A when the user exercises through the sports apparatus 10000A, so that the state of the internal magnetic control device 100A may be adjusted by the difference between the actual power of the sports apparatus 10000A and the calibration power of the sports apparatus 10000A after the sports apparatus 10000A exercises through the following steps, so as to correct the actual power of the user when the user exercises through the sports apparatus 10000A, which is beneficial to improving the efficiency of the user exercises through the sports apparatus 10000A.

It will be appreciated that the load that the flywheel 400A achieves when driven to rotate is related to the amount by which the flywheel 400A cuts the magnetic induction lines of the inner magnetic control device 100A. Specifically, the greater the amount of magnetic induction lines of the inner magnetic control device 100A that the flywheel 400A cuts when driven to rotate, the greater the load that the flywheel 400A can achieve, at which time the user is more hard to step on the step-on device 300A. Accordingly, the smaller the amount of magnetic induction lines of the inner magnetic control device 100A cut when the flywheel 400A is driven to rotate, the smaller the load the flywheel 400A can obtain, and the more effort the user saves when stepping on the stepping device 300A.

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

To meet the different demands of the user on the load of the flywheel 400A of the sports apparatus 10000A and to correct the actual power when the user exercises through the sports apparatus 10000A to be consistent with the calibration power, the inner magnetic control device 100A of the present invention is configured to be able to adjust the relative positions of the magnetic induction lines and the flywheel 400A such that the more the flywheel 400A is positioned closer to the flywheel 400A, the more the flywheel 400A cuts the magnetic induction lines of the inner magnetic control device 100A when driven to rotate, and accordingly, the less the flywheel 400A cuts the magnetic induction lines of the inner magnetic control device 100A when driven to rotate, the more the position of the magnetic induction lines of the inner magnetic control device 100A is away from the flywheel 400A. Thus, by adjusting the relative positions of the magnetic induction line of the inner magnetic control device 100A and the flywheel 400A, on the one hand, the resistance value of the user when stepping on the stepping device 300A can be adjusted, and on the other hand, the actual power and the calibration power of the user when exercising through the movement apparatus 10000A can be corrected to be uniform.
