Piezoelectric automatic power supply method and device for wireless mouse

Abstract

The invention discloses a piezoelectric automatic power supply device for a wireless mouse, and relates to the technical field of electromechanical control. The piezoelectric automatic power supply device comprises a piezoelectric cantilever beam, an energy collection module, an energy storage capacity and a backup self-charging battery module, wherein an output part of the piezoelectric cantilever beam is connected to an input part of the energy collection module; the energy collection module is electrically connected with the energy storage capacitor; the energy collection module is electrically connected with the backup self-charging battery module; and the piezoelectric cantilever beam is arranged at the lower part of a mouse key. Meanwhile, the invention further discloses a piezoelectric automatic power supply method for the wireless mouse on the basis of the device. The mouse key is utilized for clicking, and the piezoelectric cantilever beam converts mechanical energy generated during clicking of the mouse into electric power, so that the self-power supply target of the mouse is achieved. Meanwhile, the piezoelectric cantilever beam is arranged at the lower part of a middle key of a mouse wheel and in the radial direction of a side key, so that the efficiency of converting the mechanical energy into the electric power is further improved and the electric power output is improved.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to a wireless mouse energy supply device. Background technique [0002] As a daily office product, the mouse is widely used by people. It can be divided into two types: wired and wireless. The wireless mouse is favored by consumers because it does not have the constraints of wires. , pollution, the most helpless thing is not knowing when there is no electricity; at the same time, with the development of electronic microcomputer technology and advanced integrated circuit technology, the disadvantages of using traditional chemical dry batteries as energy sources also appear. Dry batteries have limited energy and limited life. It causes serious pollution to the soil and cannot meet the needs of sophisticated and complex integrated microcomputer systems. The piezoelectric vibration energy harvesting device has attracted much attention and application due to its simple...
