The ST1 feet of the GND pin earth lead GND of piece U1, chip U1 meet transmitting coil L1, another chip termination U1's of transmitting coil L1
ST2 pins；
The wireless charging receptor includes receiving coil L2, and the coil midpoint pin of coil L2 connects the ground of wireless charging receptor
The positive pole of the one terminating diode D1 of line AGND, coil L2, the positive pole of another terminating diode D2 of coil L2, diode D1's
Negative pole connects the negative pole of diode D2, and the one end with electric capacity C4 and 5V outfans are connected, the other end and wireless charging of electric capacity C4
The ground wire AGND of electric receptor is connected.
Alternating current is converted to unidirectional current by the charger of wireless charging part, then is converted electrical energy into by wireless charging emitter
For magnetic energy, by magnetic field by energy transmission, the wireless charging receptor of bracelet portion receives magnetic energy, and magnetic energy is converted to again
Electric energy, and charged the battery by galvanic mode, this process realizes wireless charging, then gives avoidance bracelet mainboard by battery
Power supply, realizes the various functions of bracelet, and this bracelet need not connect charging wire when charging, by magnetic energy in space and electric energy
Changing can complete charging process, solve because blind person can not regard thing, cause using not square to battery charging during avoidance bracelet
Just problem.
Compared with prior art, the invention has the beneficial effects as follows：
Blind person's avoidance bracelet of wireless charging of the present invention, without the need for connecting charger by wired mode, when blind person applies, only needs
Bracelet is placed on wireless charging emitter the charging for being capable of achieving battery, it is to avoid battery is filled when blind person is using avoidance bracelet
Electric inconvenient problem.
Description of the drawings
Fig. 1 show the theory diagram of the present invention；
Fig. 2 show the wireless charging transmitter circuit schematic diagram of the present invention；
Fig. 3 show the wireless charging acceptor circuit schematic diagram of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 show the theory diagram of the present invention, and wireless charging blind person's avoidance bracelet is by wireless charging part and bracelet portion
Two parts are divided to constitute, wireless charging part is made up of charger and wireless charging emitter, bracelet portion is received by wireless charging
Device, battery and avoidance bracelet mainboard composition.
Alternating current is converted to unidirectional current by the charger of wireless charging part, and charger uses market common 5V, 2A
Charger for mobile phone, connects wireless charging emitter, and by wireless charging emitter magnetic energy is converted electrical energy into, by magnetic field by energy
Transmission, the wireless charging receptor of bracelet portion receives magnetic energy, and magnetic energy is converted to electric energy again, and by galvanic side
Formula charges the battery, and this process realizes wireless charging；Again avoidance bracelet main board power supply is given by battery, realize the various work(of bracelet
Can, this bracelet need not connect charging wire when charging, and charging process can be completed by the conversion of magnetic energy in space and electric energy,
Solve because blind person can not regard thing, the problem of battery is charged when causing to use avoidance bracelet inconvenience.
Fig. 2 show the circuit theory diagrams of wireless charging emitter, and wireless charging emitter is by chip U1 ---
SGM46000 meets power supply VCC as master chip, the VCC feet of U1, and the CK_RS feet of U1 connect one end of electric capacity C1 and electric capacity C2, electric capacity
The other end earth lead GND of another termination capacitors C2 of C1, the MODE feet of U1 connect one end of electric capacity C3 and resistance R1, electric capacity C3 and electricity
The other end of resistance R1 is connected, and the GND pin earth lead GND of earth line GND, U1, the ST1 feet of U1 meet transmitting coil L1,
