High-efficiency self-generator

A high-efficiency self-generator comprising:

• a rotating body assembly including an outer rotor that is formed to be rotatable with a first central axis as a center point and a plurality of inner rotors that are formed to be rotatable with a second central axis positioned between the first central axis and the outer rotor as a center point;
• a power generation device that is connected to the outer rotor and generates electricity by rotation of the outer rotor;
• a pedal device configured to convert an external force generated by a user into a rotational driving force;
• a gear device configured to rotate the inner rotors by transmitting the rotational driving force generated by the pedal device to the inner rotors;
• a reduction device configured to change a power transmission ratio between the pedal device and the gear device;
• a starting device configured to rotate the outer rotor by transmitting the rotational driving force generated by the pedal device to the outer rotor;
• and
• a gear control device configured to intermittently rotate the inner rotor by periodically intermitting driving of the gear device,
• wherein the pedal device includes:
• an operating pedal that is operable by a user by applying an external force;
• a first power generation gear formed to rotate by the external force applied to the operating pedal;
• and
• a second power generation gear formed to rotate by the external force applied to the operating pedal,
• wherein the gear device includes:
• a first mainspring assembly provided to receive a rotational driving force generated by the pedal device and wind and tension a first mainspring;
• a first reverse rotation unwinding prevention unit that prevents the first mainspring from reversely rotating in a wound state;
• and
• a transmission gear array including a plurality of power transmission gears for transmitting a restoring force of the first mainspring to the inner rotor, and
• wherein the gear device further includes:
• a first reduction gear formed to share a central rotating shaft of the first mainspring;
• and
• a second reduction gear formed to share the central rotating shaft of the first mainspring, and
• the reduction device includes:
• a first base gear provided to engage with the first power generation gear;
• a first adjustment gear formed to share a central rotating shaft with the first base gear to form a first reduction ratio by selectively engaging with the first reduction gear;
• and
• a second adjustment gear formed to share the central rotating shaft with the first base gear to form a second reduction ratio by selectively engaging with the second reduction gear.
