Remote Control Power Supply {Device for supplying power of remote control}

The present invention relates to a remote control power supply device, a ratchet gear which is rotatable in only one direction, a plurality of gears and a generator for engaging the ratchet gear is built-in, by rotating the handle of the remote control mounted on the ratchet gear The present invention relates to a remote control power supply device in which the generated current is stored in an electric double layer capacitor, and the current output from the electric double layer capacitor can be used as a main power source of the remote control.

Most electronic products used in homes such as televisions and audio devices are provided with a remote controller for the convenience of the user. However, since the remote control has to be used by inserting a small battery, it is inconvenient to replace the consumable battery with a new one after a certain period of time. In addition, in a remote control such as an air conditioner or a fan, there is a problem in that strong alkaline liquid leaks from the battery when it is stored for a long time without corrosion. In addition, not only economic loss is caused by the replacement of the battery, but also frequent damage occurs in the battery case. In particular, in case of an unconscious moment such as discharging, the inconvenience of having to prepare a spare battery always comes. In addition, the conventional remote controller has a large amount of power consumed by each element such as the IC, LED, resistance, etc. mounted inside, it was not possible to think of inserting and using a generator or capacitor to generate its own power inside the remote controller. .

The present invention has been made to solve the above drawbacks, by simply rotating the handle of the remote control mounted on the ratchet gear that is rotatable in one direction to increase the speed of the rotor of the plurality of gear parts and the generator at high speed and Another object of the present invention is to provide a remote control power supply device in which a DC current generated therefrom is stored in an electric double layer capacitor to be used as a main power source of the remote control.
