Description
Technical field
The present invention relates to the wireless power field, relate in particular to a kind of wireless power supply that utilizes indicator screen.
Background technology
Be the multimedia epoch now, various audio ﹠ video equipments emerge in an endless stream, and simultaneously supporting with it ancillary equipment is also more and more.Such as, a lot of products such as the wireless mouse of using on the computer, bluetooth earphone, wireless router all need the power supply power supply.Owing to there has not been the restriction of connection, make this kind equipment use than traditional equipment and made things convenient for a lot, also can allow environment for use purify and be convenient to and put in order.Therefore, since wireless device one appears on the scene, just become the favorite in market, market is increasing, and range of application is more and more wider.Yet also there is a lot of shortcomings in this kind equipment.Such as wireless router, though saved communication line, the supply of power supply still needs electric wire, and can't be real accomplish is wireless, needs special-purpose power supply, all is subjected to certain restriction and inconvenience for laying and using.And for wireless mouse, though can realize powered battery, because the power consumption of wireless mouse is higher than traditional mouse.For using the dry cell power supply mouse, must change battery in use for some time, if there is not reserve battery, then use is brought inconvenience, if the preparation battery, then also there is the problem of life-span and loss in reserve battery, and, dry cell is a kind of product of not environmental protection, and discarded battery pollutes environment, has also increased use cost.And for using rechargeable battery powered mode, must charge before using.Therefore, need be some accessories of its supporting periphery of charging, its shortcoming is to have problems such as loose contact, use inconvenience.According to top described, the problem of these two kinds of products has represented the powerup issue of two quasi-representatives.How finding a kind of solution and reasonable configuration mode that can one, is the key that addresses the above problem.
Summary of the invention
For solving the problem of above-mentioned wireless device power supply inconvenience, the invention provides a kind of formula wireless power supply that shields simply, efficiently.
For achieving the above object, the present invention adopts following scheme:
A kind of screen formula wireless power supply comprises display, it is characterized in that: also comprise control circuit, drive circuit, power circuit and energy transmission loop, described control circuit, drive circuit, power circuit and energy transmission loop are arranged on display interior; Control circuit produces control signal and sends to drive circuit; Drive circuit provides the driving signal according to control signal for power circuit; Power circuit provides the electric energy of setting power and frequency according to driving signal for energy transmission loop; Energy transmission loop converts electrical energy into the magnetic energy emission.
In this case, the coil that is used for the magnetic energy emission in the energy transmission loop places display, such as computer monitor, the computer monitor periphery contains a lot of wireless devices, such as mouse, mobile phone etc., and as long as these wireless devices place in the coil magnetic field coverage, just can charge simultaneously.
Further, energy transmission loop is provided with the coil for the magnetic energy emission, and coil places display side frame inside.The coil magnetic field coverage can be bigger on the one hand, can not increase the volume of display on the other hand.
Further, control circuit comprises wave generator circuit, waveform modulated circuit, feedback processing circuit and control and management circuit; Wave generator circuit is for generation of sine waveform, and sine wave is sent to the waveform modulated circuit; The waveform modulated circuit is for the waveform to required frequency that the sine wave that receives is modulated; The feedback processing circuit is used for the alternating current of described power circuit output is carried out feedback processing; The control and management circuit is used for the The whole control circuit is managed.
Further, control circuit is realized by dsp chip.
Beneficial effect: (1) energy sends coil and the LCD profile matches, reasonable use the space, the outward appearance of having beautified the energy transtation mission circuit has general practicality.(2) adopt monitor power supply, just can guarantee charging as long as wireless mouse is in the display magnetic field range, and need not dismantle rechargeable battery, make charging process more efficient, and the present invention not only can power to mouse, power also can for other wireless device simultaneously.
