Abstract

The invention discloses a wireless mouse device without a battery. The wireless mouse device comprises a wireless mouse body and a mouse pad. A shell of the wireless mouse body comprises a USB (universal serial bus) or PS (play station) / 2 interface, a roller, touch keys, a PCB (printed circuit board), an optical lens and a power device; in the power device inside the wireless mouse body, a magnet is mounted at the tail of the mouse body, a coil is mounted between the roller and the magnet, two ends of the coil are respectively connected to alternating-current input ends of a diode rectifier bridge, direct-current output ends of the diode rectifier bridge are respectively connected to two input ends Vin and GND of a voltage stabilizer after being connected with an energy-storage capacitor in parallel, and an output end and an input end GND of the voltage stabilizer and a filter capacitor are connected in parallel and then are used as a mouse voltage source; and closed coils which are arrayed and are distributed equidistantly are arranged in the mouse pad, and the closed coils are wound in a single-loop manner. The wireless mouse device solves the problem that a battery of the traditional wireless mouse needs to be frequently detached and installed, and hazards caused by dry batteries to environments are relieved.

Description

technical field [0001] The invention relates to a wireless mouse, in particular to a battery-free wireless mouse device. Background technique [0002] With the development of computer technology and the needs of mobile office and mobile life in the future world, small wireless mice are more and more popular among the public because of their small size and lightness. At present, a traditional wireless mouse usually consists of a transmitter (mouse body) and a USB receiver. When working, the USB receiver is directly connected to the USB interface of the computer, and is directly powered by the computer power supply; because the transmitter is wireless, it is generally powered by one or two dry batteries on the market at present, and the dry batteries are detachable. [0003] The traditional wireless mouse requires the user to frequently disassemble and install the battery, or replace the battery with a new one, or take out the rechargeable battery for charging and then rei...
