Electromagnetic conversion module one and electromagnetic conversion module two realize the conversion between electric energy and electromagnetic wave as follows.Respectively have a coil in transmission and receiving terminal, transmitting terminal coil connects cable power generation electromagnetic signal, and the electromagnetic signal of the coil-induced transmitting terminal of receiving terminal thus generation current charge the battery.Wireless charging technology is completely not by electric wire, utilize the technology that magnet is equipment charge, namely utilize transmission charge in the air of magnetic resonance between charger and equipment, coil and capacitor then form resonance between charger and equipment, realize electric energy high efficiency of transmission.
Described electromagnetic conversion module one is containing high-frequency generator and amplifying circuit.
Described electromagnetic conversion module two is containing low-frequency oscillator and amplifying circuit.
Operation principle of the present utility model:
A kind of panel computer of wireless power, after wireless charger passes into domestic power supply, through electromagnetic conversion module one, alternating current is converted to electromagnetic wave by high-frequency generator and amplifying circuit, launched by the parabolic antenna of transmitter module and realize microwave power transmission, the receiver module of panel computer main body receives electromagnetic wave, respond to into direct current, and then be reverse into alternating current with the low-frequency oscillator of electromagnetic module two and amplifying circuit, adapter carries out changing into direct current input battery component according to battery required voltage electric current, completes charging.
Embodiment:
Because the microwave transmission after conversion is divergence expression transmission, and the signal that panel computer receiver module receives is regional reception, so just can cause the energy waste of signal transmission, add that the distance of signal transmission is one to one limited, also can cause power supply signal limited coverage area, for problem above, using wireless charger as base station, establish several signal reflex devices in space around base station, the microwave that transmitter module is launched is at spatial, and the signal that panel computer receiver module receives this range of receiving region converts current versus cell assembly to and charges, and all the other signals that Base Transmitter is gone out, through RC integrated concussion radiating circuit, signal is launched again after receiving to the integrated receiving circuit of LC in the signal reflex device set, then panel computer receiver module receives the signal reflected back through sender unit, thus make Base Transmitter signal major part out can be received for charging by panel computer, reduce the waste of the energy, the signal launched due to signal reflex device is also emanative, so not every signal can reflex to panel computer, but can Base Transmitter out not by the signal major part that panel computer absorbs reflex on panel computer for charging, therefore the efficiency of panel computer charging can be improved, do not waste energy, because the principle of wireless power is electromagnetic conversion, so signal has dividing of power, central area signal is strong, edge regions signal is weak, closely signal is strong, and distant signal is weak, and the Signal reception emitted can be launched by signal reflex device again, after cause this enhances the signal utilization of edge regions, also extend the distance that signal is launched, add the overlay area of signal, make panel computer wireless power more convenient, apart from farther, charging rate is fast.
In sum; after those of ordinary skill in the art reads the utility model file; make other various corresponding conversion scheme according to the technical solution of the utility model and technical conceive without the need to creative mental labour, all belong to the scope that the utility model is protected.
