Preferably, wireless charging shell of the present invention and built-in reception antenna thereof can not affect mobile phone existing capability in charging process.
Compared with prior art, the beneficial effect of wireless charging mobile phone shell of the present invention is as follows:
Can provide wireless charging function for the existing mobile phone that does not configure wireless charging module;
Do not need existing mobile phone to carry out any change;
Do not affect the existing capability of mobile phone;
Be widely used, the receiver module of other portable type electronic products can be provided, realize wireless charging function.
Accompanying drawing explanation
Fig. 1 is the mobile phone wireless charging principle figure consistent with the embodiment of the present invention;
Fig. 2 is the mobile phone wireless charging shell consistent with the embodiment of the present invention.
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 it is converted to 5V～20V direct current by power supply.The signal that this voltage can obtain according to wireless receiving circuit 6 and coil sample circuit 5 feedbacks by communication and control circuit 3 carrys out adjusting size; DC power supply after electric power management circuit 2 conversions is to the higher-order of oscillation and power amplification circuit 4 power supplies; Because electric power management circuit 2 can regulation voltage, therefore can be by regulating the output voltage of electric power management circuit 2 control power output on wireless transmission coil 8.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 comprised of efficient D class power amplifier or bridge-type (half-bridge or full-bridge).The high-frequency square-wave signal that microprocessor in communication and control circuit 3 produces flows to tuning circuit 7 and transmitting coil 8 after high-frequency oscillating circuits and power amplifier 4 amplifications.Wireless transmission coil 8 regulates resonance by shunt capacitance 7, make coil can resonance in the frequency of needs transmitting.
5 pairs of coil currents of coil current sample circuit are sampled and are 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 then by the bridge rectifier in rectification and voltage stabilizing circuit 11, are converted to 4.2V DC power supply, 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 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%), to 8 transmittings of wireless receiving coil; When efficiency is more than charging critical point, but during lower than optimum charging scope, can guarantee that mobile phone can be by quick charge by increasing transmitting power.
Confirm after said process, the charge power that wireless transmission coil 8 continues to send optimization is to wireless receiving coil 9.
Wireless interface receiving end monitoring battery state, after battery has charged; By wireless interface Power Generation Road 12, by wireless receiving coil 9, to transmitting terminal coil 8, send charging ending request.
Reflector complete charge, enters monitoring holding state.
As shown in Figure 2, the surface-mounted integrated circuit of wireless receiving circuit, rectification and voltage stabilizing circuit, charging inlet circuit and receiving coil etc. 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.Integrated rectification and 17 pairs of high-frequency signals that receive of voltage stabilizing circuit of embedding phone housing inside carry out rectification 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.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
