In this particular embodiment of the exercise apparatus 1000 of the present invention, the magnets 112 of the flywheel 110 are disposed on the magnet holding surface 1102 of the wheel disc 111 with two magnetic poles facing outward, and the electromagnet 120 can sequentially pass through the two magnetic poles of the magnets 112 when the flywheel 110 is driven to rotate.

In the process that the driving member 230 drives the driving wheel 220 to rotate relative to the supporting frame 210, the driving wheel 220 drives the driving belt 240 and the flywheel 110 of the self-generating assembly 100 to rotate, and then the self-generating assembly 110 generates electric energy based on the electromagnetic induction principle. The heat of the user in the process of using the fitness equipment 1000 can be converted into electric energy, so that the interaction between the fitness equipment 1000 and the user is increased, and the interestingness of the fitness equipment 1000 is further improved.

It should be noted that the specific embodiment of the driving member 230 is not limited, and the driving member 230 allows driving by pedaling, stepping, hand shaking, hand pushing, hand pulling, etc. Also, the specific embodiment of the equipment body 200 is not limited, and the equipment body 200 may be implemented as an elliptical machine, a spinning bike, a rowing machine, or a sports apparatus known to those skilled in the art. Moreover, it will be understood by those skilled in the art that the specific embodiments of the exercise apparatus body 200 disclosed in the text and drawings herein are merely exemplary and should not be construed as limiting the scope and content of the exercise apparatus 1000 of the present invention.

The fixture body 200 includes a console 250 and a display 260, wherein the display 260 is communicatively coupled to the console 250 and the console 250 is communicatively coupled to the magnetic control mechanism 300. The console 250 can process the data acquired by the magnetic control mechanism 300 to obtain exercise data of the user during the exercise, such as, but not limited to, exercise speed, exercise power, heat consumption, exercise time, etc. The display screen 260 displays the exercise data generated by the console 250 to facilitate a user to grasp exercise conditions in real time.

Further, the display screen 260 allows the level control command to be selected or input, the console 250 sends the level control command to the magnetic control mechanism 300, and the magnetic control mechanism 300 adjusts the distance between the magnetic attraction surface 301 and the magnetic conduction surface 1101 of the wheel disc 111 of the flywheel 110, so as to keep the load of the flywheel 110 during rotation corresponding to the level control command.

Preferably, the coil 122 of the electromagnet 120 of the self-generating assembly 100 is electrically connected to the console 250 and the display screen 260, and the electromagnet 120 can provide power supply for the console 250 and the display screen 260.

In an embodiment of the present invention, the self-generating assembly 100 further includes an electricity storage mechanism 130, wherein the coil 122 of the electromagnet 120 is electrically connected to the electricity storage mechanism 130, and the electric energy generated by the coil 122 of the electromagnet 120 can be stored in the electricity storage mechanism 130 when the flywheel 110 rotates, so as to avoid waste of the electric energy. Further, the power storage mechanism 130 is electrically connected to the magnetic control mechanism 300, the encoder 600, the console 250, and the display screen 260, and the electric power stored in the power storage mechanism 130 can be supplied to the magnetic control mechanism 300, the encoder 600, the console 250, and the display screen 260. Thus, the electric energy generated by the self-generating component 100 is prevented from being wasted, and the use experience of the fitness equipment 1000 is improved.

For example, when the user is just beginning to exercise, the user tends to be physically vigorous, and when the user rapidly drives the flywheel 110 to rotate, the rate of change of the magnetic flux passing through the electromagnet 120 is large, the electromagnet 120 generates more electric energy, and if there is still residual electric energy after supplying the magnetic control mechanism 300, the encoder 600, the console 250 and the display screen 260, the residual electric energy is stored in the electric storage mechanism 130. When the user is tired, the rotation speed of the flywheel 110 is reduced, the electric power generated by the electromagnet 120 is less, and at this time, if the instant electric power generated by the electromagnet 120 is not enough to support the normal operation of the magnetic control mechanism 300, the encoder 600, the console 250 and the display screen 260, the power storage mechanism 130 starts to provide the electric power supply for the magnetic control mechanism 300, the encoder 600, the console 250 and the display screen 260.

That is, the electromagnet 120 can directly supply power to the magnetic control mechanism 300, the encoder 600, the console 250, and the display screen 260, and can also indirectly supply power to the magnetic control mechanism 300, the encoder 600, the console 250, and the display screen 260 through the power storage mechanism 130. The power storage mechanism 130 may be integrated with the electromagnet 120, or may be implemented as two separate parts from the electromagnet 120. It should be understood by those skilled in the art that the manner in which the power storage mechanism 130 and the electromagnet 120 cooperate is exemplary only and should not be construed as limiting the scope and content of the exercise apparatus 1000 of the present invention.
