Description

Charger for lithium electric equipment
Technical field
The utility model is related to a kind of charger more particularly to a kind of chargers for lithium electric equipment.
Background technology
Mobile phone market in the early stage, each mobile phone are equipped with a dedicated charger, do not only result in family face charger Type is various, and leads to the significant wastage of device resource;Later, State-level had unified the specification of phone charger, was all USB interface charges, and changes this unordered state;Now, USB charger, USB power source, either in family, still All it is ubiquitous in office space, automotive interior;Output voltage is that the USB power source of 5 V becomes the mark of entire society Quasi- configuration.
With the development of lithium power technology, lithium electricity power supply unit is more and more;USB power source cannot meet since voltage is relatively low The power demands of these lithium electric equipments, thus each lithium electric equipment is required for being equipped with a dedicated charger, is used for 220 V The alternating current of left and right becomes the safe voltage of 36 V or less direct currents, in order to realize this function, it is necessary to the alternating current including high pressure Be reduced to the circuit module of low-voltage DC, this by cause buy a dedicated charger for lithium electric equipment cost compared with It is high.
This is the deficiencies in the prior art place.
Invention content
The technical issues of the utility model solves is to combine existing USB power source, provides a kind of filling for lithium electric equipment Electric appliance, it can greatly reduce cost.
The charger for lithium electric equipment of the utility model, including:Shell;Input interface, the voltage being sequentially connected electrically Translation circuit, cable and output interface;Input interface, voltage conversion circuit are fixed and are closed by shell;It is characterized in that:Institute It is USB interface to state input interface;It is the whole of lithium battery charging voltage that voltage conversion circuit, which is used to increase the voltage of input interface, Several times.
The voltage conversion circuit is charge pump booster circuit, inductance boost circuit or transformer booster circuit.
The voltage of the output interface is 8.4V, 12.6V, 16.8V, 21V, 25.2V, 29.4V or 33.6V.
The USB interface of the utility model can connect existing USB power source, can be with by the boosting of voltage conversion circuit 5 V USB power sources below are transformed to the integral multiple of lithium battery charging voltage, to charge for lithium electric equipment.Due to avoiding High Level AC Voltage is reduced to the circuit module of low-voltage DC, and the utility model can be such that totle drilling cost substantially reduces, and small, just In storage and storage.
Description of the drawings
Fig. 1 is the overall structure diagram of the charger of the utility model.
Specific implementation mode
The operation principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this Utility model is not intended to limit the utility model.
If the charger of Fig. 1, the utility model include shell 1, USB input interfaces 2, voltage conversion circuit 3,4 and of cable Charging interface 5;Charger is inserted into general USB power source, the V1 boost in voltage that voltage conversion circuit inputs USB is to set Voltage V2 the output interface of charger is inserted into the charge port of lithium electric equipment, so that it may to charge for lithium electric equipment;
The V1 of low-voltage boosts to V2 by the work of booster circuit;Booster circuit technology is very ripe, commonly It is divided into charge pump career, inductance boost and transformer boosting;Charge pump simple, spy at low cost, being unable to high current with circuit Point is widely used in signal control;Transformer boosting has the characteristics that isolation, safety, power are big, volume is also big, of high cost, Extensive utilization power inversion industry;Inductance type has the characteristics that efficient, circuit is moderate, price is also moderate, electric current is changeable, The present invention just uses this kind of booster circuit;
The charging voltage CV of lithium battery is limited, and household is exactly commonly 36V lithium battery packs below, mostly 2,3,4, 5,6,7, the 9 or 10 section concatenated battery pack of lithium battery;For simplify product, be designed to output 8.4V, 12.6V, 16.8V, 21V, 25.2V, 29.4V or 33.6V fix the charger of output, i.e. charging voltage is above-mentioned fixed value.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, though So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession Member, in the range of not departing from technical solution of the present invention, when the technology contents using the disclosure above make a little change or repair Decorations are the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, technology according to the present invention is real Any simple modification, equivalent change and modification made by confrontation above example still fall within the range of technical solution of the present invention It is interior.
