Description
Technical field
The utility model relates to the wireless charging technology, and particularly a kind of handheld device wireless charging device further relates to a kind of mobile phone wireless charging device.
Background technology
Along with the fast development of electronic technology, handheld devices such as mobile phone, PDA(Personal Digital Assistant), MP3 player, digital camera appear in our life more and more.Be exposed to outside the shell contaminatedly easily but the wired charging inlet of handheld device also occurred, easy ageing comes in contact problems such as bad and handheld device charging inlet different model be incompatible.The appearance of wireless power technology has solved the problems referred to above well.
The wireless power technology is the magnetic field that utilizes the transmitting coil be positioned at charger under the alternating current effect, to change; The coupling coil that is positioned at the charging object charges for the charging object through the electromagnetic induction received energy and through treatment circuit, has realized wireless power.
In order to realize wireless charging, the charging object must increase the circuit that receives and handle electric energy.At the equipment that uses, it is unpractical transforming circuit for.
The wireless power technology need not to connect the convenience of charging inlet for people have brought charging, but does not also realize real intellectuality, can not discern handheld device automatically, begins or stop to charge automatically, for the equipment of different model corresponding charging service is provided automatically.
Summary of the invention
The purpose of the utility model is to provide a kind of wireless charging device, but this wireless charging device comprises wireless charging platform and wireless charging battery, and handheld device need not to transform, just can be through the charging of wireless charging platform but only need load onto the wireless charging battery.This wireless charging platform through radio frequency identification (RFID) but carry out communication with the wireless charging battery, can discern the handheld device of different model and begin or stop charging automatically, realize purpose of energy saving, and help applying.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of wireless charging device, but comprise wireless charging platform and wireless charging battery.
Described wireless charging platform comprises power module, main control module, oscillation module, transmitting antenna, reception antenna and demodulation amplification module.It is system's power supply that described power module is changed direct current with civil power; Oscillation module sends oscillator signal through transmitting antenna; Main control module can be controlled oscillation module and modulate, and delivers to main control module but reception antenna receives the signal that sends from the wireless charging battery through the demodulation amplification module.
But described wireless charging battery comprises coupled antenna, power management module, battery main control module, load-modulate module, demodulation module, charge management module and a lithium battery.Coupled antenna is through the electromagnetic induction received energy; Through power management module is system's power supply; Be lithium cell charging through charge management module simultaneously; Battery master control module controls load-modulate module can be sent signal to the wireless charging platform, and demodulation module is delivered to the battery main control module to the signal demodulation that the wireless charging platform sends over.
But the wireless charging battery is not during near the wireless charging platform, and the wireless charging platform is in holding state, external emittance, but only the wireless charging battery is carried out poll.
But when wireless charging battery during near the wireless charging platform, but the wireless charging battery receives the request signal of wireless charging platform, promptly sends answer signal.The wireless charging platform begins but the wireless charging battery is charged after receiving answer signal.Carry out the lithium battery state-detection simultaneously.Lithium battery is full of and stops charging when but electricity or wireless charging battery leave charging platform automatically, gets into holding state.
The utility model has beneficial effect.
1, convenient, it is promptly chargeable to need not to connect power line, and can be the multiple handhold equipments charging simultaneously.
2, can discern, begin automatically charging, automatic complete charge automatically, more energy-conservation, more humane.
3, but the wireless charging platform can carry out communication with the wireless charging battery, can discern the handheld device of different model.
As long as 4, but handheld device loads onto this wireless charging battery and just can pass through this wireless charging Platform Implementation wireless charging, need not to change the handheld device circuit, helps the popularization of wireless charging technology.
