<p>A portable power generating device comprises a stator (1) and a rotor (4) coaxial with each other. The rotor (4) rotates around a shaft. The stator (1) is provided with a plurality of iron cores. Metal coils (2) are wound on the iron cores. The metal coils (2) are connected with each other. The rotor (4) is provided with magnet bodies (3) opposite to the metal coils (2). The rotor (4) has an eccentric wheel structure. The device further comprises a plurality of piezoelectric bodies (5) and a voltage processing unit. An end of each piezoelectric body (5) is fixed on the stator (1), and the piezoelectric bodies (5) are connected with each other. The voltage output terminal of the piezoelectric bodies (5) and the voltage output terminal of the metal coils (2) are connected with the voltage processing unit respectively. Voltages output from the piezoelectric bodies (5) and the metal coils (2) are rectified by the voltage processing unit respectively, and then are output after filtered together. The portable power generating device can automatically convert energy generated by natural motions of a human body in various directions to electric energy, and thus can be used as a working power supply of an intelligent terminal.</p> |
