Description
Technical field
The utility model, which is related to, a kind of can realize the POS of wireless charging.
Background technology
Traditional financial terminal equipment (financial POS) is typically powered by power supply adaptor and lithium battery is filled
Electricity.Commonly used power supply adaptor has 5V, 8V and 9V, is typically to be made up of shell, power transformer and rectification circuit.Due to
The limitation of voltage and current, for different manufacturers, for the financial terminal equipment of different model, can only configure different adaptations
Device, and an adapter is only a traditional financial POS terminal and is powered and charges, while also suffering from the limit in space
System, especially for intelligent POS new at present, frequently plug can cause a certain degree of damage to charge port, while very
Difficulty realizes the sealing technology of water proof and dust proof performance.
The content of the invention
The technical problems to be solved in the utility model is：The wireless charging of financial POS machine.
In order to solve the above-mentioned technical problem, the technical solution of the utility model, which there is provided, a kind of can realize wireless charging
POS, including the POS casing and charging base being separated from each other, provided with working cell and for working cell in POS casing
There is provided the power subsystem of operating voltage, it is characterised in that the charging electricity charged for power subsystem is additionally provided with POS casing
Road, reception antenna is connected via change-over circuit is received with charging circuit；
Transmitter is provided with charging base, transmitter includes power management module, and direct current is directly accessed power management
Module, electric main accesses power management module via full bridge rectifier, and the output end connection transmitting of power management module turns
Change circuit, transmitting change-over circuit connection transmitting antenna.
A kind of financial terminal equipment that the utility model is provided, with wireless charging function, its wireless charging is a kind of profit
With Faraday's electromagnetic induction law, the electric energy of feeder ear is transferred to so as to it by POS lithium battery by space magnetic field coupling
The technology charged, this is a kind of brand-new charging method for meeting Qi standards, overcomes traditional financial POS charging method
Drawback, can make charging more flexibly, conveniently, safely.The utility model can sufficiently reduce the space-consuming of adapter, subtract
Few charging interval so that whole charging process is more humane, more meets the present use habit of user, has the following advantages that：
1) wireless charging function can make POS break away from the constraint of charge cable；
2) charge cable plug number of times is reduced, the stability of system can be improved to a certain extent；
3) exposure of charging port is reduced, water proof and dust proof performance is improved.
4) support of the equipment to wireless charging, can make it share a nothing with the smart machine of other support wireless chargings
Line charger；
5) one-to-many charging simultaneously can be achieved, socket space is liberated；
6) future can support portable charging, and solving portable hand-held POS, battery electric quantity is not enough in use
Problem；
7) input voltage range that can be born is wider, and output voltage is relatively stablized.
Brief description of the drawings
A kind of electrical schematic diagram for POS that can realize wireless charging that Fig. 1 provides for the utility model；
Fig. 2 is wireless charging circuit schematic diagram.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Overall wireless charging system of the present utility model is made up of transmitting terminal and receiving terminal two parts, transmitting terminal and reception
Hold and be made up of the coil that can be resonated in same frequency.Electric main is passed through the emitted end line of power management module by radiating circuit
Circle produces magnetic field, and by producing electric current after the coil coupling of receiving terminal, galvanic current is produced after receiving change-over circuit, right
Lithium battery is charged.
Specifically, with reference to Fig. 1 and Fig. 2, a kind of of the utility model offer can realize the POS of wireless charging, including phase
The POS casing and charging base mutually separated, working cell is provided with POS casing and operating voltage is provided for working cell
Power subsystem, it is characterised in that be additionally provided with POS casing for power subsystem charge charging circuit, reception antenna warp
It is connected by reception change-over circuit with charging circuit；
Transmitter is provided with charging base, transmitter includes power management module, and direct current is directly accessed power management
Module, electric main accesses power management module via full bridge rectifier, and the output end connection transmitting of power management module turns
Change circuit, transmitting change-over circuit connection transmitting antenna.
During wireless charging, electric main is changed into direct current, Huo Zhezhi by input by full bridge rectifier
Direct-flow input end is connected on to be powered system by direct current, then by power management module processing, by the direct current after processing
Electricity supplies transmitting antenna by after active crystal oscillator inversion, being converted to the alternating current of high frequency.Reception antenna coupling firing antenna
Energy, exports an alternating current, then by receiving change-over circuit, converts thereof into direct current and carried out for the lithium battery in equipment
Charging.Several equipment are placed on mat simultaneously, can be charged simultaneously.
As shown in Fig. 2 in whole charging process, wireless charging transmitting terminal and this financial terminal are separate, it is not necessary to
Any cable is attached, and is only associated by the electromagnetic induction of transmitting antenna and reception antenna.Financial terminal when in use
It will not be constrained by charge cable, as long as after use is terminated, continuing to put back to the table top provided with charging base.Charger
The magnetic field of generation is very weak, and can only be transmitted between the coil that same frequency resonates, thus can to equipment charge but not
The article and other equipment of magnetic recording data near influence.
The course of work of the present utility model is：The compatibility volume tradition charging of this financial terminal equipment is different with two kinds of wireless charging
Charge mode, the reception antenna and change-over circuit needed for built-in wireless charging, are filled using wireless charging mode in a device
When electric, as long as this financial terminal equipment, which is positioned on the wireless charger transmitting station of configuration, can complete charging operations, utilize
Electromagnetic induction principle and related alternating current impression technology, by the transmitting antenna in transmitting terminal base and POS shell on the back
Reception antenna produces sensing and charged, and energy conversion efficiency reaches as high as 80% in whole charging process, suitable with tradition charging
Orchestration energy conversion efficiency remains basically stable.
