Disclosed is a power supply device, comprising a storage battery (1), a power generating device (2), at least two transmission mechanisms (3) and a generator (4), wherein an output end of the storage battery is electrically connected to an input end of the power generating device, each transmission mechanism is connected to an output end of the power generating device, an output end of one transmission mechanism is in transmission connection with an input end of the generator via a pulley set (5), and an output end of the generator is electrically connected to an input end of the storage battery; and an output end of the other transmission mechanism is a power supply output end (6). The power supply device integrating electric energy with mechanical energy not only realizes a power supply without depending on an external energy source, but also has the advantages of a simple structure, clean and environmentally friendly features, a wide application range and low cost. |
