Abstract
The invention relates to a fingerprint identification electronic device with the functions of wireless charging and wireless power supplying. It is currently well known that for fingerprint identification electronic devices such as a fingerprint identification mobile phone and a fingerprint identification tablet computer, charging and power supplying are performed in a wired mode. Charging and power supplying can be performed on the fingerprint identification electronic device through a power source in a wireless mode, and both wireless charging and wireless power supplying can be performed on the same fingerprint identification device. According to the adopted scheme for solving the technical problem, a power wireless transmitter transmits electromagnetic waves through a reflector, and the electromagnetic waves are transmitted to a wireless electric energy receiver to the fingerprint identification electronic device through space so that charging and power supplying can be performed on the fingerprint identification electronic device.
Description
Technical field
The present invention relates to the fingerprint recognition electronic equipment that a kind of wireless charging is powered.
Technical background
Current known fingerprint recognition electronic equipment, as fingerprint recognition mobile phone, the fingerprint recognition electronic equipments such as fingerprint recognition panel computer fill power supply for wired, separate when wireless charging and wireless power, can not be simultaneously used in same fingerprint recognition electronic equipment. can not realize same fingerprint recognition electronic equipment namely can wireless charging also can wireless power. restricted between fingerprint recognition electronic equipment and power supply, can not move freely.
Summary of the invention
The object of the invention is; Power supply wirelessly charges to fingerprint recognition electronic equipment and powers, same fingerprint recognition electronic equipment 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 fingerprint recognition electronic equipment, 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 fingerprint recognition electronic equipment; Replace conventional fingerprint identification electronic equipment power source 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.
Benefit of the present invention is; Unrestricted between fingerprint recognition electronic equipment and power supply, can move freely.
Below in conjunction with accompanying drawing, the invention will be further described
