[0026] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0027] This embodiment provides a self-generating control system for sports and fitness equipment, such as Figure 1 As shown, it includes a transmission assembly 9, a main control module 3, a power generation device 1, a conversion module 2, an electric energy storage device 4, a first switch module 5, a second switch module 6 and an electric drive device 7;

[0028] The transmission assembly 9 on the sports and fitness equipment is connected to the power generation device 1, and is used to generate current through the transmission assembly 9 and the power generation device 1 when the sports and fitness equipment is in motion;

[0029] The conversion module 2 is connected to the power generation device 1, the main control module 3, the electric energy storage device 4 and the electric drive device 7 respectively, and is used to convert the current form of the power generation device 1 and transmit the converted current to the main control module 3, the electric energy storage device 4 and the electric drive device 7;

[0030] The first switch module 5 is connected to the main control module 3 , the electric energy storage device 4 , the conversion module 2 and the electric drive device 7 respectively, and the second switch module 6 is connected to the electric energy storage device 4 and the conversion module 2 respectively.

[0031] The self-generating control system provided in this embodiment can be applied to sports and fitness equipment such as rowing machines, elliptical machines and fitness bikes. When this embodiment is applied to a fitness bike, specifically, as mentioned in the patent document with application number: CN202321497355.7, "the fitness bike includes a frame and a flywheel, the flywheel and the AC generator 10 are mounted on the frame, the rotating shaft of the flywheel is provided with a belt groove, the AC generator 10 is provided with a pulley, and the AC generator 10 is connected to the flywheel through a belt. "Therefore, the transmission component 9 in this embodiment can adopt the existing technology consistent with the existing self-generating sports and fitness equipment. The transmission component 9 is connected to the power generation device 1, which is used to convert the mechanical energy of the sports and fitness equipment into electrical energy through the power generation device 1. It is convenient to set up and will not be described in detail.

[0032] Among them, the electric drive device 7 of this embodiment can be used to drive various external lifting or telescopic devices on sports and fitness equipment. For example, when this embodiment is applied to an exercise bike, the electric drive device 7 can be used to drive the seat height of the exercise bike to automatically rise and fall, etc., which is a clever arrangement.

[0033] like Figure 1 As shown, the power generation device 1 is a generator 10, and the conversion module 2 includes a front-stage rectifier circuit 20, a front-stage voltage stabilizing circuit 21, a diode 22 and a rear-stage voltage stabilizing circuit 23;

[0034] The input end of the front-stage rectifier circuit 20 is connected to the output end of the generator 10, and is used to convert the alternating current of the generator 10 into direct current. The output end of the front-stage rectifier circuit 20 is connected to the input end of the front-stage voltage stabilizing circuit 21. The output end of the front-stage voltage stabilizing circuit 21 is connected to the input end of the electric energy storage device 4 through the diode 22. The output end of the front-stage voltage stabilizing circuit 21 is connected to the input end of the rear-stage voltage stabilizing circuit 23. The output end of the rear-stage voltage stabilizing circuit 23 is connected to the main control module 3.

[0035] The power generation device 1 of this embodiment adopts a generator 10, and the current it generates is alternating current. Therefore, the function of the front-stage rectifier circuit 20 is to convert the alternating current generated by the generator 10 into direct current. The front-stage voltage stabilizing circuit 21 of this embodiment adopts a DC-DC voltage stabilizing circuit, and its function is to stabilize the DC voltage converted by the front-stage rectifier circuit 20 at the highest charging voltage of the electric energy storage device 4. For a battery energy device, its charging voltage can be adjusted according to actual conditions, and the front-stage voltage stabilizing circuit 21 also needs to be adjusted accordingly. A diode 22 is arranged between the output end of the front-stage voltage stabilizing circuit 21 and the input end of the electric energy storage device 4 to achieve a unidirectional conductive function, which is used to protect the safety of the electric energy storage device 4. In addition, by setting a rear-stage voltage stabilizing circuit 23, the electric energy output by the front-stage voltage stabilizing circuit 21 can be further finely adjusted to ensure that the voltage finally delivered to the main control module 3 meets the working requirements, so as to improve the stability and reliability of the system. The specific circuit schematic diagram is shown in FIG. Figure 2 shown.

[0036] like Figure 1 As shown, the main control module 3 is MCU30, and the post-stage voltage stabilization circuit 23 includes a post-stage voltage stabilization power supply 230 and a 3.3V voltage stabilization circuit 231. The output end of the front-stage voltage stabilization power supply is connected to the post-stage voltage stabilization power supply 230, and the post-stage voltage stabilization power supply 230 is connected to MCU30 through the 3.3V voltage stabilization circuit 231.

[0037] Since the main control module 3 of this embodiment adopts MCU30, the post-stage voltage stabilizing circuit 23 is provided with a 3.3V voltage stabilizing circuit 231, but not limited thereto, to ensure that the MCU30 can work stably and improve the stability of the system. Figure 2 shown.

[0038] like Figure 1 As shown, the electric energy storage device 4 is a battery pack 40, and the battery pack 40 is provided with an input interface 400 and an output interface 401. The output end of the front-stage voltage stabilizing circuit 21 is connected to the input interface 400 of the battery pack 40 through a diode 22, and the output interface 401 of the battery pack 40 is connected to the rear-stage voltage stabilizing power supply 230 and the electric drive device 7 respectively through a first switch module 5.

[0039] This embodiment uses a battery pack 40 as the electric energy storage device 4, which can efficiently store the electric energy generated by the power generation device 1. When the power generation device 1 stops working, the battery pack 40 can quickly release the stored electric energy to provide a stable power supply for the system. The user can adjust the electric energy capacity of the battery pack 40 according to actual conditions. The specific circuit schematic diagram is shown in FIG. Figure 2 shown.

[0040] like Figure 1 As shown, the first switch module 5 is an electronic switch 50, and the MCU 30 is connected to the electronic switch 50 to control the on and off of the electronic switch 50; the second switch module 6 is a mechanical switch 60, and the mechanical switch 60 is provided with a switch interface 61, and the output interface 401 of the battery pack 40 is connected to the post-stage regulated power supply 230 through the switch interface 61.

[0041] The first switch module 5 of this embodiment adopts an electronic switch 50, which has an extremely fast response speed, so that the MCU 30 can quickly control the on and off of the electronic switch 50, meeting the system's demand for fast response. Among them, the MCU 30 can control the power supply and power off of the electric energy storage device 4 to the electric drive device 7 by controlling the on and off of the transistor in the electronic switch 50, which has a simple structure and convenient operation.

[0042] The second switch module 6 of this embodiment adopts a mechanical switch 60. Due to its physical structure and operating principle, when the power generation device 1 stops, the second switch module 6 can ensure the stability of the response when controlling the energy storage device 4 to supply power to the conversion module 2 and the electric drive device 7.

[0043] like Figure 1 As shown, an external power supply module 41 is also included. The battery pack 40 is provided with an external charging interface 402 , and the external power supply supplies power to the battery pack 40 through the external charging interface 402 .

[0044] The battery pack 40 of this embodiment is provided with an external charging interface 402, so that the battery pack 40 can flexibly obtain power supplement through the external power supply module 41, ensure stable power supply to the electric drive device 7, and improve the stability of the system.

[0045] like Figure 1 As shown, it also includes an external serial port module 80, a wireless module 81 and a lighting module 82. The external serial port module 80 is connected to the post-stage voltage-stabilized power supply 230 and the MCU30 respectively, and the wireless module 81 and the lighting module 82 are connected to the MCU30 respectively.

[0046] In this embodiment, the MCU 30 can communicate with other external devices such as a host computer through a serial port module 80, and the MCU 30 can receive control instructions or data from the external device, making the control process more flexible. Of course, the number of external serial port modules 80 can be multiple, as an expansion interface of the system, so as to connect more external devices or sensors, further increasing the flexibility of the system.

[0047] In addition, the wireless module 81 of this embodiment can adopt a 2.4G wireless module 81, so that the MCU30 can communicate with external devices through the wireless module 81, thereby realizing remote control. The lighting module 82 can adopt an atmosphere light, but is not limited to this. The lighting module 82 can help users more intuitively understand the current working status of the system or whether there is an abnormality. Of course, the wireless module 81 and the lighting module 82 can also be selected and set according to actual needs in other embodiments. The specific circuit schematic diagram is shown in FIG. Figure 2 shown.

[0048] like Figure 1 As shown, the electric drive device 7 includes a motor 70 and a motor drive chip 71 , and the motor drive chip 71 is connected to the motor 70 , the MCU 30 , the first switch module 5 and the 3.3V voltage stabilizing circuit 231 respectively.

[0049] The motor driver chip 71 of this embodiment integrates multiple functions required for controlling the motor 70, reducing the complexity of the system. Through the rotation of the motor 70, various external lifting or retracting devices on the sports and fitness equipment can be automatically controlled. For example, when applied to a fitness bike, the seat height of the fitness bike can be automatically raised or lowered, which is convenient to use. The specific circuit schematic diagram is shown in FIG. Figure 2 shown.

[0050] The preferred solution further includes a position sensor 72 , which is connected to the MCU 30 and is used to obtain the rotation state of the motor 70 .

[0051] In this embodiment, the position sensor 72 cooperates with the motor driver chip 71, so that the MCU 30 can accurately control the speed, direction and torque of the motor 70, so as to accurately control the external devices on the sports and fitness equipment and improve the use efficiency. Of course, the position sensor 72 can also be selected and set according to actual needs in other embodiments. The specific circuit schematic diagram is shown in FIG. Figure 2 shown.

[0052] This embodiment also provides a method for controlling the self-generation of a sports and fitness equipment, which uses the above-mentioned self-generation control system for sports and fitness equipment. The control method is as follows:

[0053] When the sports and fitness equipment is used, the sports and fitness equipment drives the power generation device 1 to start through the transmission component 9, and the power generation device 1 supplies power to the main control module 3, the electric energy storage device 4 and the electric drive device 7 through the conversion module 2. The main control module 3 controls the electric energy storage device 4 to synchronously supply power to the conversion module 2 and the electric drive device 7 through the first switch module 5, and the main control module 3 disconnects the power supply from the electric energy storage device 4 to the electric drive device 7 through the first switch module 5;

[0054] When the sports fitness equipment is not in use, the power generation device 1 stops, the second switch module 6 controls the energy storage device 4 to supply power to the conversion module 2 and the electric drive device 7, and the main control module 3 disconnects the energy storage device 4 from supplying power to the electric drive device 7 through the first switch module 5.

[0055] When the power generation device 1 of this embodiment is started, the main control module 3 controls the electric energy storage device 4 to synchronously supply power to the conversion module 2 and the electric drive device 7 through the first switch module 5, so that the power generation device 1 and the electric energy storage device 4 can simultaneously supply power to the electric drive device 7. When the power generation device 1 stops, the second switch module 6 controls the electric energy storage device 4 to supply power to the conversion module 2 and the electric drive device 7, so that the electric energy storage device 4 can continue to supply power to the electric drive device 7, and the main control module 3 can cut off the power supply from the electric energy storage device 4 to the electric drive device 7 through the first switch module 5, so as to realize automatic power-off when no one is using it, thereby improving the safety of use.

[0056] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
