Description
[technical field]
The utility model relates to communication equipment field, particularly relates to a kind of POS equipment of realizing wireless charging.
[background technology]
The most common charging solution has just adopted electromagnetic induction at present, by the coil-induced generation electric current of primary and secondary, thereby energy is transferred to receiving terminal from transmission ends, and this solution provider comprises companies such as Britain Splashpower, U.S. WildCharge and Fulton Innovation.We can see from the Splashpower website, the said firm can be implemented on the charging pad at present charges simultaneously to a digital camera and a mobile phone, but the spokesman of the said firm is also in recent expression, its first have the consumer end product of Splashpower function will can be in the front generation second half year in 2008.By comparison, the commercialization of Fulton company performance is better, and declaration cooperates to promote its technology with Motorola, furnitur manufacturer Herman Miller and Visteon company of automobile component manufacturer.In fact, the electromagnetic induction solution there is no too many mystique on technology realizes, China domestic BYD company, as far back as in December, 2005 application (publication number is 1707905, open day is 2005.12.14) non-contact induction type charger patent, just used the electromagnetic induction technology.The measure that therefore present this field supplier takes makes product go on the market as early as possible exactly, becomes " de facto standard " in this field, thereby becomes final de facto standard.
Radio wave is that another develops comparatively mature technique, and its basic principle is similar to the crystal receiver of early stage use.The Powercast of representative company in this field represents that the micro high efficiency receiving circuit of its final development can capture the radio wave energy of rebounding from wall, keeps galvanic current to press when making adjustment with load.Only need a transmitter that is installed in wall body plug, and " mosquito type " receiver that can be installed in any low-voltage product, the Powercast solution just can change into direct current with radio wave, is the battery charge of different electronic installations in about 1 meter scope.At present, the said firm has signed cooperation agreement with Philips company.
Another kind of under study for action technology still is an electromagentic resonance.The research team that is led by the physics professor Marin Soljacic of the Massachusetts Institute of Technology (MIT) utilizes this technology to light two meters outer 60 watts of bulbs, and it is named as WiTricity.The coil diameter that uses in this experiment reaches 50cm, also can't realize commercialization, if dwindle coil dimension, received power also can descend naturally.Therefore, they estimate that in the coming years finally developing to be safely the wireless charging product of notebook computer and miscellaneous equipment.
POS hand-held set charging at present all is to need charger, uses cable to connect and just can charge.The hand-held set part of split POS also is by charging with the contact that contacts of base.Selling a kind of wireless charger on the Chinese market, but it is not a wireless charging truly, only is a reserve battery yet.The wireless charger that we are discussed herein is not meant and just can transmits electric energy by physical connection, is embodied as the purpose of the less relatively electronic product charging of power consumption such as mobile phone, MP3, bluetooth earphone.Any hope can be carried out the equipment of wireless charging, all needs embedded receiver, and this increases the cost and the weight of product possibly, and forms the problem of " chicken and egg ".In addition, the charger of different company and be recharged the incompatible of equipment also will become the real difficult problem of wireless charging technology, thus the consumer's that slows down the speed of accepting.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of POS equipment of realizing wireless charging, has realized need not the cable connection and just can charge to POS equipment.
The utility model is achieved in that a kind of POS equipment of realizing wireless charging, comprise POS machine body and charging pad, be provided with the wireless secondary coil module in the described POS machine body, the output of described wireless secondary coil module is connected with a charging circuit, and the output of described charging circuit is connected with the battery of POS machine body; Described charging pad is provided with wireless primary coil module, and the input of described wireless primary coil module is connected with power management module, and described power management module is electrically connected with the city; Described POS machine body is the hand-held set of handheld POS machine or split POS.
Advantage of the present utility model is: comprise POS machine body and charging pad, be provided with the wireless secondary coil module in the described POS machine body, the output of described wireless secondary coil module is connected with a charging circuit, and the output of described charging circuit is connected with the battery of POS machine body; Described charging pad is provided with wireless primary coil module, and the input of described wireless primary coil module is connected with power management module, and described power management module is electrically connected with the city.The utility model has been realized POS equipment is carried out wireless charging, and is convenient and simple for operation, is very easy to the user.
[description of drawings]
Fig. 1 is a hardware structure diagram of the present utility model.
[embodiment]
Realize the POS equipment of wireless charging, as shown in Figure 1, form by POS machine body 10 and charging pad 20, be provided with the wireless secondary coil module in the described POS machine body 10, the output of described wireless secondary coil module is connected with a charging circuit, and the output of described charging circuit is connected with the battery of POS machine body 10; Described charging pad 20 is provided with wireless primary coil module, and the input of described wireless primary coil module is connected with power management module, and described power management module is electrically connected with the city; Described wireless secondary coil module and described wireless primary coil module have produced electromagnetic induction and have produced electric current, thereby energy has been transferred to receiving terminal from transmission ends; Wherein said POS machine body 10 be handheld POS machine or the hand-held set of split POS if described POS machine body 10 is hand-held sets of split POS, then described charging pad 20 is arranged in the split support of hand-held set of split POS.
Its novel operating principle is:
1, the transmitting terminal of charging pad 20 by power management module to wireless primary coil module alternating current in addition.
2, thereby the electric current of alternation is in the wireless primary coil module magnetic field that electric field changes that changes.
3, when receiving terminal wireless secondary coil module and wireless primary coil module near the time, then enter into the magnetic field of the variation that wireless primary coil module produces, by electromagnetic induction, produce induced current at the wireless secondary coil module.
4, the charging circuit of receiving terminal, the electric current that utilizes induction to produce is realized battery is charged, thereby has realized the wireless charging to POS machine body 10.
What deserves to be mentioned is that the interactive mode between wireless secondary coil module described in the utility model and the wireless primary coil module not only is confined to electromagnetic induction, it can also produce the charge power supply of POS machine battery by the mode of radio wave and electromagentic resonance.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
