The utility model provides a kind of USB quick charge adapter; Comprise the adaptor body that is built-in with the integrated circuit that is used to draw high charging current; One end of adaptor body has the USB terminal; The other end of adaptor body has USB port, and said USB terminal and USB port all are connected on the integrated circuit.

Preferably, said integrated circuit also is connected with and is used for Intelligence Selection switching circuit that charging current is controlled.

Preferably, said integrated circuit also is connected with and is used for multi-gear switch that charging current is controlled.

Technique scheme can be found out; Because the utility model embodiment adopts the built-in adaptor body that is used to draw high the integrated circuit of charging current; Therefore can the output current of the USB port of existing notebook computer or desktop computer computer be drawn high, thereby shortened charging interval charging device.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the three-dimensional structure diagram of USB quick charge adapter among theutility model embodiment 1;

Fig. 2 is the structure principle chart of USB quick charge adapter among theutility model embodiment 1.

Embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment 1:

Like Fig. 1, shown in Figure 2; The utility model embodiment provides a kind of USB quick charge adapter; Comprise theadaptor body 1 that is built-in with the integratedcircuit 11 that is used to draw high charging current; One end ofadaptor body 1 hasUSB terminal 2, and the other end of adaptor body hasUSB port 3, and said USB terminal and USB port all are connected on the integrated circuit 11.Said integratedcircuit 11 also is connected with and is used formulti-gear switch 4 that charging current is controlled.

Particularly; For the ease of carrying; The body ofadaptor body 1 is designed to the structure and shape of common U disk; End atadaptor body 1 sets firmlyUSB terminal 2, andUSB terminal 2 can be one-body molded withadaptor body 1, can also design an end cap certainly and be used for when adapter does not use or portable type covers USB terminal 2.In the process of using,USB terminal 2 is inserted on the USB port of notebook computer or desktop computer computer, power supply is incorporated into the integratedcircuit 11 of adaptor body;Integrated circuit 11 is used for charging current is drawn high, and can adopt existing electric current to draw high circuit or Current Control chip, and the charging current that integratedcircuit 11 is introduced the USB terminal draws high; The highlyest can charging current be pulled up to 1.5A; And the charging current after will drawing high exports charging device to through the USB port on thisadaptor body 3, and like equipment such as the ANDROID PHONE among Fig. 2, IPAD, hence one can see that; Charging current can be pulled up to 1.5A by existing 0.5A; Charging current value has been drawn high 2 times, and charging rate just obtains accelerating so, so can effectively reduce the charging interval.

In order to control more accurately to the charging current of charging device; Charging device is carried out better charge protection, and integratedcircuit 11 also is connected with and is used formulti-gear switch 4 that charging current is controlled in the present embodiment, andmulti-gear switch 4 is a kind of manual gas shut offs;Multi-gear switch 4 is on different gears the time; Have the different potential signal and be sent to integrated circuit, concrete implementation can adopt the mode of electric resistance partial pressure to realize, can certainly adopt other mode to realize; Can no longer too much give unnecessary details with reference to existing technical data here.Illustrate the operation principle of multi-gear switch below, for example, when the charging device ofUSB port 3 connections is IPAD; Multi-gear switch is chosen in first gear and puts; This moment, corresponding electric resistance partial pressure was X, and voltage X is transferred to integrated circuit, so the voltage X on this reception pin of integrated circuit identification; And corresponding with the value of integrated circuit storage, thereby the amplitude that draws high of control charging current is X1.When the charging device ofUSB port 3 connections is ANDROID PHONE; Many grades are chosen in second gear by switch and put; This moment, corresponding electric resistance partial pressure was Y, and voltage Y is transferred to integrated circuit, so the voltage Y on this reception pin of integrated circuit identification; And corresponding with the value of integrated circuit storage, thereby the amplitude that draws high of control charging current is Y1.Like this,,, charging current is controlled, can be protected charging device through the gear of manual selection multi-gear switch for different charging devices.

Embodiment 2: as another execution mode, substitute the multi-gear switch in theforegoing description 1 with the Intelligence Selection switching circuit in the present embodiment, promptly integrated circuit is connected with and is used for Intelligence Selection switching circuit that charging current is controlled.It is understandable that this Intelligence Selection switching circuit also can be integrated in the integrated circuit; Be to establish the Intelligence Selection switching circuit in the integrated circuit; After charging device is connected to the USB port of adaptor body; Integrated circuit can be known the portable equipment type from the USB port of adaptor body, controls the Intelligence Selection switching circuit then and carries out corresponding change action, causes the maximum current and the portable equipment coupling that is connected of the USB port output of adaptor body.

More than USB quick charge adapter that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the execution mode of the utility model are set forth, the explanation of above embodiment just is used to help to understand the core concept of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
