The purpose of the invention of this utility model is to provide a wireless rechargeable mobile phone based on the existing mobile phone communication system, which realizes remote wireless charging function and combines communication and charging after improvement based on the above existing problems.

The technical scheme that the utility model adopts is as follows:

The utility model relates to a wireless rechargeable mobile phone, which includes a communication system and a transmitting end, and the communication system includes a microprocessor, a baseband processor and a transceiver antenna; the microprocessor is connected to the baseband processor, and the baseband processor is also connected to the transceiver antenna; the transceiver antenna is also connected to an energy collection module, which includes an energy conversion circuit, an energy storage device, and an energy management module; the microprocessor is connected to the energy management module, and the microprocessor is provided with a digital controller; the energy The collection module and communication system are integrated on the circuit board.

With the above structure, the mobile phone can not only communicate normally, but also can receive the electromagnetic wave emitted by the transmitter, and convert it into electric current through the antenna to charge the mobile phone. Outdoors, as long as the electromagnetic wave of the base station can be received, it can be charged without limitation. Suitable for charging distance, suitable for mobile phone charging.

The utility model relates to a wireless rechargeable mobile phone. The energy conversion circuit is a rectification and voltage doubling circuit and a detection circuit; the rectification and voltage doubling circuit includes a MOS tube and a capacitor, and the capacitor C1 is connected in series with a parallel circuit, and the parallel circuit is a MOS1 tube And the series circuit of the capacitor C2, and the parallel connection of the series circuit of the MOS2 tube and the capacitor C3.

In the above rectified voltage doubler circuit, when the signal flows in the negative direction, the MOS1 tube is turned on, and the MOS2 tube is turned off, and the charge flows from the capacitor C2 into the capacitor C1. After charging, the MOS1 tube is turned off; The current flows from the capacitor C1 to the capacitor C3, and finally the charge in the capacitor C2 is transferred to the capacitor C3, and the capacitor outputs a DC current, and the output voltage is greater than the input voltage, and the output voltage is higher.

The utility model relates to a wireless rechargeable mobile phone. The energy management module includes a power management circuit. The power management circuit is a parallel circuit composed of an inductance L connected in series with MOS4 tubes and a diode D. At the same time, the diode D is connected in series with a C4-R parallel circuit.

In the above power management circuit, when the MOS4 tube is turned off, the current flows through the inductor clockwise and generates a magnetic field, and the left side of the inductor is the positive pole; when the MOS4 tube is turned on, the current will decrease due to the high impedance; in order to keep the load continuous The current of the current flows, and the magnetic pole of the previously generated magnetic field will reverse (now the left side of the inductor is negative), so that it becomes two power supplies connected in series; this series power supply generates a higher voltage and gives it to Capacitor C is charged. If the switching cycle of the MOS4 tube is very short, the inductor will not be completely discharged between the two charging processes, so when the MOS4 tube is turned on, the voltage at both ends of the load will always be higher than the input voltage of the power supply; The capacitor connected in parallel will be charged. With the MOS4 tube turned off, the right circuit is shorted, so that the capacitor can provide energy for the load, and the existence of the diode also ensures that the current will not flow through the left circuit.

The utility model relates to a wireless rechargeable mobile phone. The transceiver antenna is a dual-frequency antenna, including a patch, a grounding plate, a dielectric substrate and a feeder line; the grounding plate is provided with a dielectric substrate, and there is a patch on the dielectric substrate The feeder is connected to the patch; two L-shaped slots of equal size and opposite directions are opened on the patch.

With the above structure, after two L-shaped slots are loaded on the patch, the base film of the patch will be disturbed to a certain extent, and its resonant frequency will also be changed accordingly. In the current distribution of the disturbed mode, the center of the patch There is a cross current nearby, its radiation direction is similar to that of the basement film, the polarization direction is the same, and the frequency ratio increases.

The utility model relates to a wireless rechargeable mobile phone. The width of the patch is close to the width of the dielectric substrate, and the length of the L-shaped groove is close to the width of the patch.

With the above structure, the width of the patch can change the positions of the two resonance points. When the width of the patch is wider, the current flow direction is longer, the lower the two resonance frequencies are, and the frequency ratio of the antenna is higher; the length of the L-shaped slot is longer. The longer the current distribution is affected by the slot, the lower the resonant frequency value will be, and the higher the frequency ratio of the antenna will be.

The utility model relates to a wireless rechargeable mobile phone. The transmitting end includes a transceiver antenna of a base station, an energy source, an energy conversion module and a communication module; the communication module performs information transmission with the mobile phone through the transceiver antenna; the energy conversion module converts energy The electric power of the source is converted into electromagnetic waves, and energy transmission is performed with the mobile phone through the transceiver antenna; the transceiver antenna is connected to the communication module and the energy conversion module, and the energy conversion module is connected to the energy source.

In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: compared with the existing wireless charging mobile phone, the utility model has the function of remote wireless charging, and this function does not need to consider the charging distance , within the scope of the base station signal, it can be charged when there is a signal, and the combination of communication and mobile phone does not affect the communication at the same time, and the cost is not high, as long as the energy source and energy harvesting device are added on the basis of the original communication system. It can be charged, which solves the problem of difficulty in charging outdoor and outdoor mobile phones.
