As shown in Figure 1, the invention discloses a kind of USB quick charge device 100 simultaneously with data transmission function,
Including the first charging interface 10 and the second charging interface 11 that can be connect respectively with a charging equipment, i.e. the USB quick charge
Device 100 can be electrically connected with two external equipments simultaneously, and the first charging interface 10 is electrically connected with the first fast charge controller 20,
Second charging interface 11 is electrically connected with the second fast charge controller 21.Second charging interface 11 passes through with the second fast charge controller 21
The one CC line electric connection for quick charge, and the second charging interface 11 also passes through a pair of data lines and the second fast charge controller
21 data communication end (DP/DM) is electrically connected, and the first charging interface 10 is fast for the CC line of quick charge and first by one
Fill the electric connection of controller 20, wherein data role swap agreement (DATE ROLE is provided in the second fast charge controller 21
SWAP), by DATE ROLE SWAP, so that the declaration of the second charging interface 11 has fast charge and data transmission function, the first charging
The data communication end (DM/DP) on data communication end (DM/DP) and the second charging interface 11 on interface 10 is electrically connected, respectively
Two charging equipments being electrically connected with the first charging interface 10 and the second charging interface 11 can pass through the first charging interface respectively
10 and the second data communication end (DM/DP) on charging interface 11 carry out data transmission.For ease of description, the present invention is implemented
In example, the external equipment connecting with the first charging interface 10 is known as equipment A 60, it is outer by what is connect with the second charging interface 11
Portion's equipment is known as equipment B 61.It follows that the first charging interface 10 and the second charging interface 11 can be respectively equipment A simultaneously
60 and equipment B, 61 quick charge, and while carrying out quick charge, equipment A 60 and equipment B 61 can also pass through data
Communication ends (DM/DP) carry out data transmission and use tool so that user does not need to buy charging equipment and HUB respectively
There is the single USB quick charge device 100 of above structure to can reach above-mentioned purpose, not only saves data, and reduce user
Store up space.
Preferably, the first fast charge controller 20 and the second fast charge controller 21 in above-described embodiment are the control of PD fast charge
Device, therefore, the first fast charge controller 20 and the second fast charge controller 21 can support one in PD3.0, PPS, QC4 fast charge agreement
Kind is a variety of.And user is when charging, and is not always the demand for having data transmission, when not needing data transmission function,
To avoid data transmission due to maloperation, further, the data communication end (DM/DP) on the first charging interface 10 is filled with second
Data communication end (DM/DP) on electrical interface 11 is electrically connected by a switching switch 4, and the first fast charge controller 20 and second is fast
It fills between controller 21 and is additionally provided with a communication wire 3, when the second fast charge controller 21 detects the by communication wire 3
When one charging interface 10 has charging equipment access, the openable switching switch 4 of the second fast charge controller 21, with the first charging of connection
Data communication channel between interface 10 and the second charging interface 11, it is further to note that the switching switch 4 can be integrated in
The inside of second fast charge controller 21 may also be arranged on the outside of the second fast charge controller 21.It is integrated when switching switch 4 such as Fig. 1
At the inside of the second fast charge controller 21, data communication end (DM/DP) and the second fast charge on the first charging interface 10 are controlled
Data expansion port (TDP/TDM) connection on device 21, data communication end (DM/DP) on the second charging interface 11 passes through the
The data on switching switch 4 and data ECP Extended Capabilities Port (TDP/TDM) and the first charging interface 10 in two fast charge controllers 21 are logical
Believe end (DM/DP) connection.Such as Fig. 2, when switching switch 4 outside of the second fast charge controller 21 being arranged in, switch switch 4 also with
A wherein control terminal on second fast charge controller 21 is electrically connected, and switches the ON/OFF of switch 4 by the second fast charge controller 21
Control.
The course of work of USB quick charge device 100 with above structure are as follows: distinguish equipment A 60 and equipment B 61
The first charging interface 10 and the second charging interface 11 are accessed, when equipment A 60 accesses the first charging interface 10, the first fast charge control
Device 20 processed tells the information that the first charging interface 10 has equipment to access to the second fast charge controller 21 by communication wire 3；The
If two fast charge controllers 21 learn that equipment A60 has accessed the first charging interface 10 by communication wire 3, and access the second charging
The equipment B 61 of interface 11 is to be enabled by CC line come when requiring fast charge, the second fast charge controller 21 can open switching switch 4
Data transmission function, at this point, the second charging interface 11 still can carry out quick charge by CC line, if the second charging interface 11 of access
Equipment B 61 when being by data communication end (DM/DP) Lai Yaoqiu fast charge, since the port DP/DM is occupied at this time, do not open
Switch switch 4, deactivates data transmission function, it is preferential to guarantee fast charge function.In addition, when the second fast charge controller 21 detects first
When charging interface 10 has equipment insertion, the power supply disconnection of the second charging interface 11 can be restarted automatically, to avoid due to equipment A
The access of 60 and equipment B 61 sequentially leads to the problem of possibly can not carrying out data transmission.Due to leading to when the second charging interface 11
The port DP/DM is crossed data transmission, therefore, the first charging cannot be used for while carrying out quick charge when requiring fast charge
Mouth 10 and the second charging interface 11 are Type-C interface or Lightning interface.
In addition, USB quick charge device 100 of the present invention further include one respectively with the first charging interface 10 and the second charging
The power modules 5 that mouth 11 is electrically connected.In the present embodiment, which can be AC/DC module and/or DC/DC module.
To sum up, the invention discloses a kind of USB quick charge device 100 simultaneously with data transmission function, the USB is fast
There are two fast charge interfaces, respectively the first charging interface 10 and the second charging interface 11 for the fast tool of charging unit 100, and first fills
Electrical interface 10 and the second charging interface 11, which respectively correspond, is provided with a PD fast charge controller, 20 He of respectively the first fast charge controller
Second fast charge controller 21, due to being provided with DATE ROLE SWAP agreement, and the first charging in the second fast charge controller 21
The data communication end (DM/DP) on data communication end (DM/DP) and the second charging interface 11 on interface 10 is electrically connected, because
This, when using the first charging interface 10 and the second charging interface 11 be two different equipment (equipment A60 and equipment B 61) into
While row quick charge, also openable switching switch 4, to start data transmission function, so that equipment A 60 and equipment B
61 can carry out mutually data transmission, i.e. equipment A 60 can be by data transmission to equipment B 61, and equipment B 61 can also be by data transmission
Give equipment A60.
The above disclosure is only a preferred example of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, still falls within the range that the present invention is covered.
