Description

A kind of wireless charging device

Technical field

The utility model relates to charging device, relates to a kind of wireless charging device in particular.

Background technology

Nowadays energy-conserving and environment-protective are developing direction of energy technology; Along with the development of radio energy-transmitting technology, progressively to the commercial field of promoting and using, radio energy-transmitting can have been practiced thrift a large amount of electric energy; And safety and environmental protection, this technology also provides the power utilization environment of a safety for disadvantaged group.But because the limitation of the means of realization, mostly there is the situation of poor stability in radio energy-transmitting equipment at present, has therefore limited the development of radio energy-transmitting technology.

The utility model content

The utility model technical problem to be solved is to realize a kind of safety and stability radio charging device.

To achieve these goals; The technical scheme that the utility model adopts is: a kind of wireless charging device; Comprise the sender unit and the recipient that match; The external 220V alternating current of the power subsystem of described sender unit and after change-over circuit is handled with power delivery to transmitter unit; The radio wave receiving element of described recipient is connected with the charging output through the circuit conversion circuit, and described recipient also is provided with the solar energy electroplax, and the electric energy that produces is delivered to the charging output after change-over circuit is handled.

Described recipient charging output is provided with USB interface or battery charge folder or battery charge box or mobile phone charging interface.

Sun-generated electric power is connected with the charging output through diverter switch with the power supply that radio wave receives.

Described charging output is provided with voltage detection unit, and described voltage detection unit detects voltage between output positive and negative charge, and according to the signal controlling diverter switch break-make that detects voltage.

Described charging output is provided with signal lamp.

Described sender unit also is provided with monitoring unit; Described monitoring unit comprises single-chip microcomputer and ultrasonic transmission/reception unit; Described ultrasonic transmission/reception unit detects the distance between sender unit and the recipient, and described single-chip microcomputer is according to the break-make of this distance signal control sender unit power subsystem output circuit.

Described monitoring unit also is provided with the display unit that is connected with single-chip microcomputer.

The advantage of the utility model is that this charging device increases solar energy and passes ability; Realize that coil coupled modes and solar energy pass the dual charging of ability; Adopt solar recharging not only to increase charging current and improve charge efficiency with the complementary mutually mode of wireless charging; The two acting in conjunction goes wrong and can continue can not cause the loss of data of some electrical appliance because of sudden power to electrical appliance power supply when one, and the various informative instructions for use that can satisfy varying environment and different crowd of this charging device charging.

Description of drawings

Face the content of every width of cloth accompanying drawing expression in the utility model specification and the mark among the figure down and make brief description:

Fig. 1 is the circuit block diagram of wireless charging device;

Fig. 2 is the work block diagram of wireless charging device;

Mark among the above-mentioned figure is: 1, sender unit; 2, recipient.

Embodiment

Can know referring to Fig. 1,2; The radio charging device comprises the sender unit 1 and recipient 2 that matches; The alternating current of the external 220V50Hz of power subsystem of sender unit 1 wherein, the power supply of input is delivered to transmitter unit after change-over circuit is handled, and the main reason rectification circuit of change-over circuit, voltage stabilizing circuit are handled power supply; Transmitter unit is made up of oscillating circuit, power amplification circuit and power amplifier drive circuit, converts the electric energy of importing to radio wave.

Recipient 2 is receive sender unit 1 radio wave that sends and the device that converts thereof into electric energy; A charging device can be equipped with a plurality of recipients 2; Like this as long as open sender unit 1; Just can charge to a plurality of equipment simultaneously at sender unit 1 periphery, the radio wave receiving element of recipient 2 is connected with the charging output through the circuit conversion circuit, also is provided with a solar energy electroplax on the recipient 2 simultaneously; The electric energy that this solar energy electroplax produces also is delivered to the charging output after change-over circuit is handled, the realization solar recharging is supplied power with the complementary mutually mode of wireless charging simultaneously.The sun-generated electric power that recipient 2 receives is connected with the charging output through diverter switch with the power supply that radio wave receives; Thereby can select wireless or solar energy charges separately, perhaps carry electricity by two kinds simultaneously, and also be provided with voltage detection unit at the charging output; This voltage detection unit detects voltage between output positive and negative charge; And, prevent that unusual damage of out-put supply is recharged object, plays the effect of protection according to the signal controlling diverter switch break-make that detects voltage.Also be provided with three indicator lights on the recipient 2; Indicator light inserts the charging output, and red led all can be luminous when circuit has output (no matter being that solar energy receives electric energy or wireless receiving to electric energy), and the green light meeting on the right side is bright when two joint No.5 cells chargings; Charging finishes green light and can knock out; The green light in centre position can be luminous when charging mobile phone battery, and charging finishes green light and can knock out, thus the operating state of prompting user charger apparatus.

In order to improve the charging device effect in energy saving and environmental protection, we also are provided with monitoring unit on sender unit 1, and this monitoring unit comprises single-chip microcomputer and ultrasonic transmission/reception unit; Wherein the ultrasonic transmission/reception unit detects the distance between sender unit 1 and the recipient 2; And single-chip microcomputer is according to the break-make of this distance signal control sender unit 1 power subsystem output circuit, and when when single-chip microcomputer draws sender unit 1 effective range according to signal in, not having recipient 2, then controlling output power supply circuit opens circuit; When in effective scope sender unit being arranged; Output power supply circuit path then, this moment sender unit 1 to send radio wave be equipment charge, monitoring unit also is provided with the display unit that is connected with single-chip microcomputer simultaneously; Show recipient 2 distance state that single-chip microcomputer detects, give user's display working condition.
