Description
Technical field
The present invention relates to a kind of charging converter, refer to especially the charging converter of a kind of selecting data charging synchronous mode or fast charge mode.
Background technology
Mobile phone (Cell Phone) is the tool of communications that the modern is indispensable, and because market is huge, each large cell phone manufacturer is all one's effort development of new mobile phone there's no one who doesn't or isn't, to win consumer's favor.But the result of letting a hundred schools contend is the problem of the derivative wasting of resources also, with current mobile phone behaviour in service, the user of significant proportion will eliminate the replacing mobile phone at set intervals, and the charging jack that the mobile phone of each famous brand adopted is all independently developed independent specification in the past, even the different product of same brand, the charging jack also may not be certain identical, under this situation, cause new cell-phone must use new charger, the charger of old mobile phone is lack scope for their abilities again, owing to suffering every year, the superseded mobile phone quantity of changing is huge, thereby discarded charger for mobile phone quantity is very surprising, according to (the GSM Association of global system for mobile communications association, GSMA) statistics, the annual charger of producing 5.1 tons of repetitions in the whole world, cause serious waste problem.For addressing the above problem, on February 17th, 2009, global system for mobile communications association announces the standard charging device specification that will use micro universal serial bus interface (Micro-USB) unified as the whole world before 2012.And European Union in the end of the year 2010 by aforementioned charger specification, by the unification of the charging jack of mobile phone, it is the micro universal serial bus interface, and will implement in full in 2012, in other words, the mobile phone of new listing all must use the micro universal serial bus interface as the charging jack.Unified specification due to the charging jack, can effectively solve wasting of resources problem, and new charger for mobile phone estimates that the comparable existing charger of its standby power consumption amount is low by 50%, thereby the advantage of achieving many things at one stroke is arranged.
As one of ordinary skill in the knowledge, USB (USB) was the technical specification of computer input/output interface originally.Therefore the pin position (PIN) of Micro-USB interface is except power pin (VBUS), also has data pin (D-, D+), with regard to the interaction mode of computer and general USB peripheral device, computer, except mutually transmitting data with the USB peripheral device, is also powered to the USB peripheral device.Once mobile phone is connected with computer by the micro universal serial bus interface, except passing data mutually between mobile phone and computer, computer also can charge to mobile phone, when (hereinafter referred to as synchronous mode) carried out in transmission data and charging simultaneously, that to transmit data be main, therefore charging current is 500mA, charging rate is relatively slow, otherwise, if do not transmit data, only simple charging (hereinafter referred to as fast mold filling formula), charging current is promoted to 700 ~ 800mA, if can maximum reach 900mA in the USB interface current boost of state-of-the-art technology U3 at present, can improve charging rate.If but existing micro universal serial bus interface is without special design, mobile phone is connected with charger or computer by the micro universal serial bus interface, must be synchronous mode, for the user who thinks merely charging, must wait for the longer charging interval, only use special-purpose charger.
From the above, charger for mobile phone will adopt the standard interface of micro universal serial bus interface as the charging jack, but under the standard criterion of USB (USB), mobile phone can only be charged under synchronous mode, otherwise must use special-purpose charger, comparatively inconvenience in the use, therefore remain further to be inquired into, and seek feasible solution.
Summary of the invention
Therefore main purpose of the present invention is to provide a kind of charging converter, it is connected between a device to be charged and charging device, so that a mode switch function to be provided, look own demand by the user and select synchronous mode or fast mold filling formula, had more in the use selectivity and convenience.
For reaching the technical way that above-mentioned purpose takes, be to make aforementioned charging converter comprise a monomer, be arranged with one first protocol interface, a second protocol interface and a switching switch on described monomer, further be provided with a switching circuit in described monomer, described diverter switch is connected with the diverter switch on monomer; Wherein:
Described the first protocol interface is a USB (universal serial bus), and it has a pair of power pin and a pair of data pin; Described second protocol interface has more than one pair of power pin and more than one pair of data pin, the power pin of the power pin of described second protocol interface and the first protocol interface is corresponding to be connected, and the data pin of second protocol interface is that the data pin by commutation circuit and the first protocol interface is connected;
Described commutation circuit is selected a synchronous mode or a fast mold filling formula by the diverter switch switching, under synchronous mode, the power pin of the first protocol interface, data pin are connected with power pin, the data pin of second protocol interface respectively, under fast mold filling formula, the first protocol interface only is connected with the power pin of second protocol interface with power pin.
With above-mentioned charging converter, can be serially connected between a device to be charged and a charging device, can first by diverter switch, select synchronous mode or fast mold filling formula before connection, if while selecting fast mold filling formula, do not set up data channel between device to be charged and charging device, therefore can treat rapidly the charging device charging with higher charging current by charging device.Described device to be charged can be mobile phone, and charging device can be computer or charger.
According to above-mentioned known beneficial effect of the present invention, be:
1. facilitating the user to look itself needs freely to select synchronous mode or fast mold filling formula.
2. when the user selects fast mold filling formula, can improve charging current, to shorten the charging interval.
3. make device to be charged applicable to the various chargers with USB (universal serial bus) output, need not use special charger.
