Fig. 2 is a kind of wireless charging power circuit principle figure of the utility model.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

Please refer to Fig.1-2, in the utility model embodiment, a kind of wireless charging circuit, including display module, input power supply Module, transmitting coil module, receiving coil module, magnetic coupling module, frequency of oscillation module, drive circuit module and MCU controls Module；The MCU control module connects frequency of oscillation module, display module and input power supply module, the frequency of oscillation respectively Module is also respectively connected with input power supply module and drive circuit module, the drive circuit module are also respectively connected with transmitting coil mould Block and transmitting coil module, transmitting coil module connect receiving coil module by magnetic coupling module, and receiving coil module also connects Connect load.

Input power supply module is also connected with DC5V-12V direct currents.

The operation principle of the utility model is：Sensed by near field, energy is transmitted to charging eventually by wireless charging device The energy received is converted into power storage in the battery of equipment by end equipment, terminal device again.What the conduction of energy used Principle is inductive coupling, it is ensured that without exposed conductive interface, the mixed and disorderly transmission line of equipment room can be not only saved, for warp The electronic equipment often contacted with conducting mediums such as liquid is all safer.

When charging panel and receiver contact, the coil in two devices is coupled by magneticaction.Electric power passes through coupling Inductor（Such as air core transformer）Receiver is transmitted to from transmitter.The method of controlling transmission electricity is sent to main device Feedback communication（Error signal）To improve or reduce electricity.Transmitter coils are in most cases all in off-position, only It is to connect to detect whether that there are receivers once in a while.If receiver can self-authentication, transmitter will remain energization State.Wireless charging principle is sensed by near field, energy is transmitted to charging terminal equipment by wireless charging device, terminal is set It is standby that the energy received is converted into power storage in the battery of equipment again.The principle that the conduction of energy uses is inductance coupling It closes, it is ensured that without exposed conductive interface, the mixed and disorderly transmission line of equipment room can be not only saved, for often being led with liquid etc. Electronic equipment present people's living needs all more safe and convenient of dielectric contact, such as mobile phone charging can be positioned over nothing It can charge on line charging module, that is, put to fill and take, without electric wire or plug action is found, improve frequent plug and draw It rises and causes loose contact or damage, realize the innovation of Switching Power Supply wireless charging, improve the efficiency entirely to charge, be convenient for people to give birth to It is living in this equipment charge domain requirement from the more energy efficient environmental protection of long-range budget.

The utility model effectively improves the problems such as equipment charge is frequent, and wire rod loose contact and charging socket are bad, nothing Similar problems can be effectively prevented by which field area use, wireless charging power supply is made to keep normal output electricity Pressure offer normal power supply and charging, it is stable and reliable for performance, the use of family and industrial equipment is not influenced, and rational design is with answering With fully hair brightness electronics technology effect meets the needs of every field life.
