Abstract
The invention provides a projection electronic device having the wireless charging function and the wireless power supply function. At present, the well-known projection electronic devices such as a projector, a projection mobile phone are charged and provided with power in a wired mode. By the adoption of the projection electronic device having the wireless charging function and the wireless power supply function, a power supply charges and supplies power to the projection electronic device in a wireless mode, the same projection electronic device has both the wireless charging function and the wireless power supply function. According to the technical scheme, a power source wireless emitter emits electromagnetic waves through a reflector, the electromagnetic waves are transmitted to the wireless electric energy receiver through space, and then the projection electronic device is charged and provided with power.
Description
Technical field
The present invention relates to the projection electronics that a kind of wireless charging is powered.
Technical background
Current known projection electronics, as projector, projection mobile phones etc. fill power supply for wired, separate when wireless charging and wireless power, can not be simultaneously used in same projection electronics. can not realize same projection electronics namely can wireless charging also can wireless power. restricted between projection electronics and power supply, can not move freely.
Summary of the invention
The object of the invention is; Power supply wirelessly charges to projection electronics and powers, same projection electronics 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 projection electronics, 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.Can a reflector, multiple receiver.Can a reflector, multiple receiver.The wireless transmission energy technologies of four patterns is known technology, and this technological invention point is this technology to quote at projection electronics, replaces conventional projection electronic equipment power source supply mode.Converged and directional transmissions electromagnetic wave by reflector, converged and directional reception electromagnetic wave by reflector.
Benefit of the present invention is; Unrestricted between projection electronics and power supply, can move freely.
Below in conjunction with accompanying drawing, the invention will be further described
Fig. 1 is, the projection electronics that a kind of wireless charging is powered
1 power supply wireless reflector 2 reflector 3 transmitting antenna 4 power supply 5 oscillator 6 radio wave 7 radio source receiver 8 reception antenna 9 filter 10 feeder ear rectifier 11 charging end rectifier 12 charging voltage and current controller 13 supply power voltage current controller 14 projection electronics in figure
In FIG
Power supply wireless reflector (1) is made up of transmitting antenna (3) power supply (4) oscillator (5), and power supply (4) becomes alternating current by oscillator (5) and becomes radio wave (6) by transmitting antenna (3).Radio source receiver (7) is made up of reception antenna (8) filter (9), radio wave (6) receives by reception antenna (8), and filter (9) is for receiving electric wave and the emitting radio waves same frequency of single pass certain frequency.Electricity is divided into two-way, and a road is that charged electrical end rectifier (11) and charging voltage and current controller (12) enter projection electronics (14).Projection electronics is charged. power supply electricity of leading up in addition is held rectifier (10) and supply power voltage current controller (13) to enter projection electronics (14) and is powered to projection electronics.Reflector (2) is for converging and electrically oriented wave.
