Abstract
The utility model discloses an energy collecting wireless mouse which comprises a wireless energy transmitting unit, a wireless energy collecting unit and a wireless mouse, wherein the wireless energy transmitting unit and a mouse signal receiving end are mounted together and are directly inserted into a universal serial bus (USB) of a computer; electric energy and signal reception are provided by utilizing the USB port; a wireless energy receiving unit is arranged inside the mouse; and the received electric energy is stored in a supercapacitor and is output to a mouse operating circuit after voltage stabilization. The inconvenience brought by the operation of replacing the battery of the traditional wireless mouse is overcome, the wireless mouse is easy and convenient to use, the working efficiency is improved, and the using cost is reduced; and in addition, because the circuit used by the wireless mouse is low in power, the radiation is low and cannot harm the human body.
Description
Technical field
The utility model relates to the wireless energy transfer field.
Background technology
At present, widely used wireless mouse all adopts the dry cell of 1.5V-3V that electric energy is provided, and uses battery not only to bring inconvenience to the user, has also caused simultaneously the pollution of old and useless battery to environment.Even but mouse adopts the powered battery of recharge, also there is the shortcoming of taking out charging inconvenience.And battery is contained in the mouse for a long time leakage can occur, and the situation of corrosion mouse causes user's property loss, has greatly increased consumer's use cost.
And along with the in recent years development of wireless energy transmission technology, adopt electromagnetic radiation, and radio-frequency antenna sends electric flux and magnetic energy, and receiving end will receive electromagnetic signal and change into direct supply.
The utility model content
The purpose of this utility model is exactly to adopt battery powered inconvenience in order to overcome existing wireless mouse, and reduces the cost that uses battery to bring.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of wireless mouse of collection of energy, this wireless mouse comprise wireless energy transmitter unit, wireless energy collector unit, wireless mouse working cell; Wireless energy transmitter unit and mouse signal receiving end are installed together, and directly are inserted on the computer USB mouth, utilize the USB mouth to provide electric energy and signal to receive; The wireless energy collector unit places mouse inner, and the power storage that receives in super capacitor, is outputed to the mouse performance circuit after voltage stabilizing.Use the 915MHz radiating circuit based on RF2514 in the described wireless energy transmitter unit, comprise operating circuit and the high-frequency power amplifying circuit of RF2514 chip; Described wireless energy collector unit uses the wireless energy collecting circuit based on P2100, comprises P2110 chip operation circuit and power output circuit; Described mouse performance circuit is general wireless mouse circuit, comprises signal receiving end and signal transmitting terminal.
Preferably, described wireless energy transmitter unit adopts the RF2514 chip, is directly powered by computer USB; Further preferred, described RF2514 chip is a kind ofly can launch 915MHh's and for the body harmless and to computer and the glitch-free electromagnetic chip of other electrical equipment.
Preferably, described high-frequency power amplifying circuit adopts transistor amplifier.
Preferably, described wireless energy collector unit adopts the P2110 chip, and further preferred, described P2110 chip can receive the 915MH electromagnetic wave, and exports 3.3V, 50mA direct supply.
