Abstract
At present, a known LED screen type portable computer is charged and powered in a wired manner. The purpose of the invention is that a power supply is used for wirelessly performing charging and power supplying on the LED screen type portable computer, and the same LED screen type portable computer can be wirelessly charged and wirelessly powered. The scheme adopted for solving technical problems is that a wireless emitter of the power supply emits electromagnetic waves through a reflector, and the electromagnetic waves are transmitted to a wireless electric energy receiver through space for performing charging and power supplying on the LED screen type portable computer.
Description
Technical field
The present invention relates to the LED screen Portable belt computer that a kind of wireless charging is powered.
Technical background
Current known LED screen Portable belt computer, as LED screen notebook computer, LED screen panel computer etc. fills power supply for wired, separate when wireless charging and wireless power, can not be simultaneously used in same LED screen Portable belt computer. can not realize same LED screen Portable belt computer namely can wireless charging also can be restricted between wireless power .LED screen Portable belt computer and power supply, can not move freely.
Summary of the invention
The object of the invention is; Power supply wirelessly charges to LED screen Portable belt computer and powers, same LED screen Portable belt computer both can wireless charging also can wireless power.
The scheme that its technical problem of solution of the present invention adopts is; Power supply wireless reflector goes out electromagnetic wave by reflector, and electromagnetic wave is delivered to radio energy recipient by space to carry out charging and powering to LED screen Portable belt computer, four patterns: 1 induction, two coils are responded to mutually.2 couplings.3 resonance: induction or the resonance of long-range serial or parallel connection electric capacity composition.4 long-range resonance: i.e. transmitting coil parallel connection or series capacitance, requires that emitting-receiving system frequency is identical simultaneously, fix up an aerial wire simultaneously at induction receiving terminal and transmitting terminal.Reflector is the metal of cauldron shape.For transmitting and receiving focusing during electromagnetic wave.The wireless transmission energy technologies of four patterns is known technology, and this technological invention point is this technology to quote at LED screen Portable belt computer, replaces traditional LED screen Portable belt computer power supply mode.Converged and directional transmissions electromagnetic wave by reflector, converged and directional reception electromagnetic wave by reflector.Supply power voltage current controller is made up of 78 serial integrated regulators, for power supply. and charging voltage and current controller is made up of 78 serial integrated regulators and pulse or switching circuit, produces pulse, for charging.Rectifier is the bridge rectifier of four diodes and filter capacitor composition. can a reflector, multiple receiver, namely multiple equipment can use a reflector simultaneously jointly. and radio source receiver is made up of reception antenna filter, reception antenna is by radio wave reception, and filter is for receiving electric wave and the emitting radio waves same frequency of single pass certain frequency.Namely LED screen is the screen of main display effect with independent LED, as the OLED screen curtain of plastic base.The LED not comprising liquid crystal combination makes the display of backlight.
Benefit of the present invention is; Unrestricted between LED screen Portable belt computer and power supply, can move freely.
Below in conjunction with accompanying drawing, the invention will be further described
