As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Therefore, features specified with terms such as "first" or "symmetric" may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, this utility model embodiment provides an electromagnetic induction power generation device suitable for fitness equipment, comprising: a wheel 1 with a front fork; an energy storage component 2 mounted on the front fork; a load tray 3 mounted on the front fork; an induction coil 4 mounted on the load tray 3; a disk 5 mounted on the spokes of the wheel 1; and a permanent magnet 6 mounted on the disk 5. The induction coil 4 and the permanent magnet 6 are correspondingly arranged but not in contact, ensuring that the permanent magnet 6 is stably positioned on the disk 5, forming an alternating magnetic field to provide a magnetic field source for electromagnetic induction power generation. When the disk 5 rotates with the moving parts, the permanent magnet 6 rotates accordingly, generating a changing magnetic field, thereby generating an induced electromotive force and realizing the power generation function.

[0026] The induction coil 4 is electrically connected to the energy storage device 2, and the energy storage device 2 is provided with a USB / Type-C output interface.

[0027] The energy storage device 2 includes an MCU microcontroller, a lithium battery or supercapacitor, and an overvoltage / overcurrent protection module. The overvoltage / overcurrent protection module has an internal bridge rectifier circuit and a voltage regulator. The induction coil 4 is electrically connected to the bridge rectifier circuit and the voltage regulator through wires. The AC power generated by the induction coil 4 is converted by the bridge rectifier circuit and then output after being stabilized by the voltage regulator, providing a stable DC power supply for subsequent energy storage and power supply.

[0028] The energy storage device 2 includes an MCU microcontroller, a lithium battery or supercapacitor, and an overvoltage / overcurrent protection module. The overvoltage / overcurrent protection module has an internal bridge rectifier circuit and a voltage regulator. The MCU microcontroller monitors the status and power generation of the lithium battery in real time and controls the operation of the overvoltage / overcurrent protection module based on the monitoring data. When an overvoltage or overcurrent occurs, the circuit is cut off in time to protect the lithium battery. At the same time, the MCU microcontroller coordinates the work of each part to ensure that the energy storage process is efficient and safe.

[0029] Lithium battery and overvoltage / overcurrent protection module, USB / Type-C output interface: The lithium battery is electrically connected to the overvoltage / overcurrent protection module and USB / Type-C output interface via wires. The overvoltage / overcurrent protection module protects the lithium battery from damage caused by overvoltage or overcurrent during charging or discharging. The electrical energy stored in the lithium battery powers external devices through the USB / Type-C output interface to meet the user's power needs.

[0030] The overvoltage / overcurrent protection module contains internal components such as a bridge rectifier circuit and a voltage regulator, which are connected via circuit board wiring. The bridge rectifier circuit converts AC to DC, and the voltage regulator stabilizes the voltage. Together, they ensure stable voltage and current input to the lithium battery, while also providing protection in case of abnormalities.

[0031] The steps for using this utility model in operation are as follows:

[0032] When the user drives the wheel 1 to rotate (such as by stepping on the pedals of a stationary bike), the disk 5 rotates with the wheel 1. The permanent magnet 6 cuts the magnetic field of the induction coil 4 and begins to generate alternating current. The alternating current generated by the induction coil 4 is converted into direct current by a bridge rectifier circuit, and then the voltage is stabilized by a voltage regulator before being input into the lithium battery.

[0033] The MCU microcontroller automatically monitors the power generation status. If the voltage / current exceeds the threshold, the overvoltage / overcurrent protection module will cut off the circuit and automatically restore it after the abnormality is resolved.

[0034] With the USB / Type-C output interface, you can connect to devices such as mobile phones and tablets using a data cable, and the electrical energy stored in the lithium battery will be output through the interface.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
