Description

Self-powered wireless mouse {WIRELESS MOUSE USING ITSELF POWER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a self-powered wireless mouse, and more particularly, to a self-powered wireless mouse capable of self-generating power required for a mouse function using a piezoelectric element.

A mouse is one of input devices that can input information to a computer such as a PC, and is an input device for moving a cursor of a computer or selecting a UI (user interface) displayed on a computer screen. Generally, a mouse is connected to a PC main body through a wired connection, and is driven by receiving power from a PC main body. A wireless mouse for wirelessly transmitting signals to a PC main body has been developed in order to solve the inconvenience caused by a wire.

The wireless mouse is driven by moving the mouse and transmitting a signal when the button is clicked to the PC body side wirelessly. At this time, the power for performing the function of the mouse is mainly used as a battery. The battery is mainly used as a rechargeable battery or a disposable battery. In case of a rechargeable battery, there is a problem that a separate charging device or a wire for charging must be connected. In the case of a disposable battery, since replacement is required after a certain period of time has elapsed, there is a problem in replacing the disposable battery.

Accordingly, in order to solve the above problems, when a mouse button is clicked, as shown in Korean Patent No. 10-1208260 (wireless mouse for self-charging using a piezoelectric body, registered on November 28, 2012, A technique for a wireless mouse capable of generating power by itself has been disclosed. However, in the case of the prior art, there is a problem in that the power generated by pushing the piezoelectric member once is not large, so that a mouse button must be clicked considerably in order to normally operate the function of the wireless mouse.
