ELECTRO-MECHANICAL DYNAMO FOR C AND D BATTERY REPLACEMENT

摘要

A self-contained electro-mechanical device incorporating a hand crank wound main spring mechanism coupled with gears to a rotating magnet inside an iron core with wound copper wire for the purpose of generating electricity. An external AC adaptor can use the generator as a motor to wind the main spring without the need to use the hand crank. An internal electronic circuit is connected to the motor/generator and mechanically coupled using a unique solenoid and clutch mechanism to prevent the main spring from turning until an external load is detected. When packaged in the form of two standard C or D size batteries this invention can be installed into devices currently using electro-chemical batteries. An internal LED light enables the device to be used as a self-contained flashlight. A mini USB connector is incorporated for charging cell phones and powering numerous devices compatible with USB power.

主权项

1. An apparatus comprising:
a) a hand crank attached to a main spring; b) the main spring attached to a first chain of gears; c) the first chain of gears attached to a generator; d) the generator attached with wires to an electronic circuit; e) the first chain of gears attached to a second chain of gears; f) the second chain of gears attached to a clutch wheel; g) the clutch wheel attached to a clutch mechanism, the clutch mechanism comprising a clutch latching mechanism and a bi-directional solenoid; h) the clutch latching mechanism linked to the hand crank by the action of removing the winding handle from the clutch mechanism when unfolding the hand crank into the winding position; i) the bi-directional solenoid attached with wires to an electronic circuit controlling the activation of the clutch mechanism; j) the electronic circuit controlling the activation of the bi-directional solenoid, storing electricity, and providing multiple output voltages;
