Title:
POWER SUPPLY CIRCUIT OF ELECTRONIC APPARATUS, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/032981
Kind Code:
A1
Abstract:
A power supply circuit (100) of an electronic apparatus, and an electronic apparatus. The power supply circuit comprises: a movement energy storage module (110) used to convert dynamic energy generated by a movement of the electronic apparatus into electric energy, store the electric energy, and supply power to the electronic apparatus; a backup battery module (120); and a switching circuit module (130) connected to the movement energy storage module and the backup battery module, and used to switch between the movement energy storage module and the backup battery module to supply power to the electronic apparatus. By utilizing a power supply method employing an energy collecting technique combined with backup battery power supply, the energy generated by the movement of the electronic apparatus can be converted into the electric energy, and the electric energy can be stored. The stored electric energy can be used to supply power to the electronic apparatus, resolving a problem of short battery life of an electronic apparatus, prolonging an operation duration of the electronic apparatus, and saving power.
