I agree with the opinion above. The original poster’s invention is sound in principle, but it may be impossible to put it into practical use in the market. The reason is clear enough. By the way, authorization of utility model patents does not mean anything. Authorization of invention patents is the first step to truly prove the success of your invention. How many authorized invention patents are there in the market? Not many can survive. There are so many ideas about pedal-powered electricity. If it had worked, products would have been launched as early as 10 years ago. . . .
One of the benefits you mentioned is battery maintenance, which is even more wrong. The unstable voltage and current of the pedals are connected in parallel with the power supply, which completely increases the burden on the power supply. That kind of power supply will break down faster, and the battery will be damaged. In terms of charging times, you are equivalent to charging the power supply at any time, and it is not stable. It is strange that the battery is not bad. . .
You can change it and use the electricity generated by the pedals for other purposes, such as car lights. Car lights do not use battery power, but use power from the pedals, which can also save power. , but the problem is still the same: the disadvantage of pedal power generation is that the voltage is unstable, which may damage electrical products at any time. . .
