Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and in particular to a low-speed power supply method and system for a generator based on a fitness bike. Background Art

[0002] An exercise bike is a relatively new fitness equipment that performs physical exercises by imitating the riding movements of a bicycle. A partial power supply method for an existing exercise bike is to generate electrical energy by utilizing the user's movements to supply the display screen and electronic watch of the exercise bike. This power supply method converts human body movements into mechanical energy, which is then converted into electrical energy through a generator or an electronic device. However, due to the user's different amount of exercise, the generator of the exercise bike may run at a low speed, thereby failing to supply power to the display screen and electronic watch of the exercise bike. Therefore, a power supply method for the generator of the exercise bike when it rotates at a low speed is needed.

[0003] The existing method of supplying power to the generator of an exercise bike at a low speed is to configure an energy storage capacitor on the exercise bike, that is, when the generator of the exercise bike rotates at a high speed, the capacitor can be used as an energy storage device to temporarily store the electric energy generated by the generator, and when the generator of the exercise bike rotates at a low speed, the stored electric energy is released to supply power to the display screen and electronic watch of the exercise bike. However, the storage capacity of the energy storage capacitor in this method is limited, and it is unable to supply high-power equipment or important equipment for a long time, and energy loss will occur, thereby reducing the power supply efficiency of the generator of the exercise bike at a low speed. Therefore, a method is needed to improve the power supply efficiency of the generator of the exercise bike at a low speed. Summary of the invention

The present invention calculates the task priority corresponding to each task in the component tasks to facilitate understanding of the urgency corresponding to each task in the component tasks, so that the component tasks can be powered first when the subsequent generator rotates at a low speed. The present invention combines the current current value, the DC voltage signal and the AC voltage signal to accurately calculate the generator. The real voltage value corresponding to the motor component is used to determine whether the power supply mode of the generator component is low-speed power supply, and then the generator component is powered by circuit conversion, which improves the power supply efficiency of the generator component. It should be understood that if the real voltage value is not greater than the preset voltage threshold, it means that the generator component is rotating at a low speed and cannot normally power the generator-related components. Therefore, the present invention combines the task priority and the automatic conversion circuit, and uses the generator component to execute the generator-related components to power the generator, which can give priority to the components that must be powered in the generator-related components, so that the fitness bike can meet the corresponding usage requirements. Therefore, the low-speed power supply method of the generator based on the fitness bike provided in the embodiment of the present invention can improve the power supply efficiency of the generator of the fitness bike under low speed conditions.
