Detailed Description
In order to describe the technical content, structural features, implementation principles and achieved objects and effects of the present invention in detail, the following description is made in connection with the embodiments and the accompanying drawings.
As shown in fig. 1, the present invention discloses a USB fast charging device 100 with data transmission function, which includes a first charging interface 10 and a second charging interface 11 that can be respectively connected with a device to be charged, i.e. the USB fast charging device 100 can be electrically connected with two external devices at the same time, the first charging interface 10 is electrically connected with a first fast charging controller 20, and the second charging interface 11 is electrically connected with a second fast charging controller 21. The second charging interface 11 is electrically connected with the second fast charging controller 21 through a CC line for fast charging, the second charging interface 11 is also electrically connected with a data communication end (DP/DM) of the second fast charging controller 21 through a pair of data lines, the first charging interface 10 is electrically connected with the first fast charging controller 20 through a CC line for fast charging, a data ROLE switch protocol (DATE ROLE switch) is disposed in the second fast charging controller 21, the second charging interface 11 is enabled to announce that the fast charging and data transmission functions are performed through the DATE ROLE switch, the data communication end (DM/DP) on the first charging interface 10 is electrically connected with the data communication end (DM/DP) on the second charging interface 11, and two devices to be charged electrically connected with the first charging interface 10 and the second charging interface 11 respectively can perform data transmission through the data communication ends (DM/DP) on the first charging interface 10 and the second charging interface 11 respectively. For convenience of description, in the embodiment of the present invention, the external device connected to the first charging interface 10 is referred to as a device a60, and the external device connected to the second charging interface 11 is referred to as a device B61. Therefore, the first charging interface 10 and the second charging interface 11 can charge the device a60 and the device B61 rapidly at the same time, and the device a60 and the device B61 can transmit data through the data communication terminal (DM/DP) at the same time of rapid charging, so that the user does not need to purchase the charging device and the HUB separately, and the above purpose can be achieved by using the single USB rapid charging apparatus 100 with the above structure, which not only saves data, but also reduces the storage space of the user.
Preferably, the first fast charge controller 20 and the second fast charge controller 21 in the above embodiments are PD fast charge controllers, and thus, the first fast charge controller 20 and the second fast charge controller 21 can support one or more of PD3.0, PPS, and QC4 fast charge protocols. When the user does not always have a data transmission requirement during charging, and when the data transmission function is not needed, in order to avoid data transmission caused by misoperation, further, a data communication end (DM/DP) on the first charging interface 10 is electrically connected with a data communication end (DM/DP) on the second charging interface 11 through a switch 4, a communication connection line 3 is further disposed between the first fast charging controller 20 and the second fast charging controller 21, and when the second fast charging controller 21 detects that the first charging interface 10 has a device to be charged accessed through the communication connection line 3, the switch 4 can be opened by the second fast charging controller 21 to communicate with a data communication channel between the first charging interface 10 and the second charging interface 11, and in addition, it should be noted that the switch 4 can be integrated inside the second fast charging controller 21 or can be disposed outside the second fast charging controller 21. As shown in fig. 1, when the switch 4 is integrated inside the second fast charge controller 21, the data communication terminal (DM/DP) on the first charge interface 10 is connected to the data expansion port (TDP/TDM) on the second fast charge controller 21, and the data communication terminal (DM/DP) on the second charge interface 11 is connected to the data communication terminal (DM/DP) on the first charge interface 10 through the switch 4 and the data expansion port (TDP/TDM) inside the second fast charge controller 21. As shown in fig. 2, when the switch 4 is disposed outside the second fast-charge controller 21, the switch 4 is further electrically connected to one of the control terminals on the second fast-charge controller 21, and the on/off of the switch 4 is controlled by the second fast-charge controller 21.
The operation of the USB quick charge device 100 having the above-described structure is as follows: the device A60 and the device B61 are respectively connected to the first charging interface 10 and the second charging interface 11, when the device A60 is connected to the first charging interface 10, the first quick charging controller 20 informs the second quick charging controller 21 that the first charging interface 10 has information of device connection through the communication connection line 3; if the second fast charge controller 21 knows that the device a60 is connected to the first charge interface 10 through the communication connection line 3, and the device B61 connected to the second charge interface 11 is connected to the second charge interface through the CC line, the second fast charge controller 21 will turn on the switch 4 to enable the data transmission function, at this time, the second charge interface 11 can still perform the fast charge through the CC line, if the device B61 connected to the second charge interface 11 is connected to the first charge interface through the data communication terminal (DM/DP), the switch 4 is not turned on because the DP/DM port is occupied at this time, the data transmission function is disabled, and the fast charge function is preferentially ensured. In addition, when the second fast charge controller 21 detects that the first charge interface 10 has a device inserted, the power of the second charge interface 11 is automatically disconnected and restarted, so as to avoid the problem that data transmission may not be performed due to the access sequence of the device a60 and the device B61. Since the second charging interface 11 cannot be used for data transmission while performing the quick charging when the quick charging is required through the DP/DM port, the first charging interface 10 and the second charging interface 11 are both Type-C interfaces or Lightning interfaces.
In addition, the USB fast charging device 100 of the present invention further includes a power module 5 electrically connected to the first charging interface 10 and the second charging interface 11, respectively. In this embodiment, the power module 5 may be an AC/DC module and/or a DC/DC module.
In summary, the present invention discloses a USB fast charging device 100 with a data transmission function, the USB fast charging device 100 has two fast charging interfaces, namely, a first charging interface 10 and a second charging interface 11, and the first charging interface 10 and the second charging interface 11 are respectively provided with a PD fast charging controller, namely, a first fast charging controller 20 and a second fast charging controller 21, respectively, because the second fast charging controller 21 is provided with a data rate switch protocol, and a data communication terminal (DM/DP) on the first charging interface 10 is electrically connected with a data communication terminal (DM/DP) on the second charging interface 11, when the first charging interface 10 and the second charging interface 11 are used for fast charging for two different devices (device a60 and device B61), the switch 4 can be opened to start the data transmission function, so that the device a60 and the device B61 can mutually perform data transmission, that is, the device a60 can transmit data to the device B61, and the device B61 can also transmit data to the device a60.
The foregoing disclosure is merely illustrative of the principles of the present invention, and thus, it is intended that the scope of the invention be limited thereto and not by this disclosure, but by the claims appended hereto.
