Brief description of the drawings
Fig. 1 is the mobile phone wireless charging principle figure consistent with the utility model embodiment;
Fig. 2 is the mobile phone wireless charging shell consistent with the utility model embodiment.
Specific embodiment
As shown in Figure 1, Mobile phone wireless charging device is powered by power supply 1, and electric power management circuit 2 is Boost-Buck circuit, and power supply is converted to 5V～20V direct current by it.This voltage can feed back according to wireless receiving circuit 6 and coil sample circuit 5 signal obtaining by communication and control circuit 3 and carry out adjusting size; DC power supply after electric power management circuit 2 conversions is powered to the higher-order of oscillation and power amplification circuit 4; Because electric power management circuit 2 can regulation voltage, therefore can control power output on wireless transmission coil 8 by the output voltage that regulates electric power management circuit 2.Tuning capacitance 7 is the frequency match for oscillating circuit.
Communication and control circuit 3 can produce the high-frequency square-wave signal that frequency range is 100KHz～250KHz, and this signal amplifies by high-frequency oscillating circuits and power amplifier 4.Amplifying coil circuit is made up of efficient D class power amplifier or bridge-type (half-bridge or full-bridge).The high-frequency square-wave signal being produced by microprocessor in communication and control circuit 3 flows to tuning circuit 7 and transmitting coil 8 after high-frequency oscillating circuits and power amplifier 4 amplify.Wireless transmission coil 8 regulates resonance by shunt capacitance 7, make coil can resonance in the frequency of needs transmitting.
Coil current sample circuit 5 is sampled to coil current and is exported analog voltage, and its voltage is corresponding with coil current value; In communication and control circuit 3, there is A/D sample circuit to read this magnitude of voltage, thus monitoring cable loop current.It can be by regulating the output voltage values of electric power management circuit 2 to realize the transmitting power of closed-loop control less radio-frequency coil 8.
Wireless receiving coil 9 and tuning capacitance 10 form receiving circuit and receive the power that wireless transmission coil 8 sends, and are then converted to 4.2V DC power supply by the bridge rectifier in rectification and voltage stabilizing circuit 11, thereby can charge to battery of mobile phone 13.In addition, the communication chip of the receiving terminal in wireless interface Power Generation Road 12 can transmit the voltage of receiving terminal and charging current to wireless transmission coil-end by wireless receiving coil 9; Thereby can calculate charge efficiency.
The concrete steps of charging are as follows:
Wireless transmission coil 8 sends low-power high-frequency signal to wireless receiving coil 9.
Wireless receiving coil 9 receives after effective high-frequency signal, and by the receiving coil voltage and current obtaining, and self ID signal returns to wireless transmission coil 8.
After wireless transmission coil 8 identification ids, confirm as effective charge mobile phone module, thereby get rid of other metals; In addition, wireless transmission coil 8 calculates the coupling efficiency between dispatch coil by the voltage and current information of the wireless receiving coil 9 that obtains; When efficiency is during lower than critical value (as below 35%), wireless receiving coil 8 is not launched; When efficiency is more than charging critical point, but during lower than optimum charging scope, can ensure that mobile phone can be by quick charge by increasing transmitting power.
Confirm after said process, wireless transmission coil 8 continues to send the charge power of optimizing to wireless receiving coil 9.
Wireless interface receiving end monitoring battery state, after battery has charged; Send charging ending request by wireless receiving coil 9 to transmitting terminal coil 8 by wireless interface Power Generation Road 12.
Reflector complete charge, enters monitoring holding state.
As shown in Figure 2, surface-mounted integrated circuit and the receiving coil etc. of wireless transceiver circuit, rectification and voltage stabilizing circuit, charging inlet circuit are all embedded in charge mobile phone shell 15.Receiving coil is connected by lead-in wire mode with surface-mounted integrated circuit.The wireless receiving coil 16 embedding can receive the high-frequency energy transmitting from wireless transmission coil.The integrated rectification and the voltage stabilizing circuit 17 that embed phone housing inside carry out rectification to the high-frequency signal receiving simultaneously, are converted to the direct current that is applicable to mobile phone charging.The integrated wireless transmission circuit 18 that embeds phone housing inside be responsible for and wireless transmission coil between communications protocol.The wireless transceiver circuit 18 that embeds phone housing inside is responsible for voltage and the current management in charging process simultaneously, and real-time monitoring cell-phone battery status, can transmit and stop charging to wireless charging emitter after mobile phone is full of.Mobile phone wireless charging shell is connected with charging mobile phone battery interface by the charging inlet 19 on the surface-mounted integrated circuit of its embedding, realizes mobile phone battery charging function.Can adjust the embedded charging inlet 19 of mobile phone wireless charging shell according to different charging mobile phone battery interfaces.
