[0002] With the increasing performance and complexity of consumer electronic devices, the requirements for charging speed using serial transmission bus are also becoming more and more stringent.

[0046] Before the present application is described in detail, a scenario of possible application of the present application is introduced.

[0047] The smart connection line related to the embodiments of the present application can be set in the smart connection line by migrating the voltage reduction function module from the electronic device, as a patch board with voltage reduction function embedded in the smart connection line, to realize voltage reduction through the smart connection line, so that there is no need to set voltage reduction chip or module in the electronic device, reducing the cost, volume and weight of the electronic device. The electronic device may, for example, be a mobile phone, a tablet computer and other electronic devices requiring data line energy transmission.

[0048] The smart connection line provided by the embodiments of the present application will be explained first as follows in combination with the accompanying drawings. The smart connection line can also be referred to as a smart cable, an active cable, an active connection line or a smart charging cable and other descriptions. Figure 1 A structural schematic diagram of a smart connection line provided by the embodiments of the present application. As shown in Figure 1As shown, the intelligent connection line can include: a first serial communication interface 10, a first active adapter board 11, a transmission cable 12, a second active adapter board 13, and a second serial communication interface 14. The first active adapter board 11 and the second active adapter board 13 are respectively mirror-imaged two adapter boards with step-down function.

[0049] The first serial communication interface 10 is connected to the first active adapter board 11, the first active adapter board 11 is connected to the second active adapter board 13 through the transmission cable 12, and the second active adapter board 13 is connected to the second serial communication interface 14.

[0050] The first serial communication interface 10 and the second serial communication interface 14 can be universal serial bus (USB) interfaces, and can be respectively used to connect the serial communication interface and the charging power supply of the electronic device. The first serial communication interface 10 and the second serial communication interface 14 can be the same type of serial communication interface, or different types of serial communication interfaces. For example, the first serial communication interface can be any type of USB interface such as USB type-A, USB type-B, USB type-C, etc., and the second serial communication interface can be any type of USB interface such as USB type-A, USB type-B, USB type-C, etc.

[0051] The first active adapter board 11 and the second active adapter board 13 can be active printed circuit boards (PCBs), which can be adapter boards with step-down function realized by PCBs. The first active adapter board 11 and the second active adapter board 13 are two circuit boards with the same structure which are respectively mirror-imaged. Since the first active adapter board 11 and the second active adapter board 13 are respectively connected to the transmission cable 12, the transmission cable 12 is equivalent to a passive inductive element, also known as a magnetic element, for the first active adapter board 11 and the second active adapter board 13, which can realize voltage domain conversion while transmitting energy.

[0052] Since the first active adapter board 11 and the second active adapter board 13 are mirror-imaged relative to the transmission cable 12, whether the first serial communication interface 10 is connected to the charging power supply and the second serial communication interface 14 is connected to the electronic device, or the first serial communication interface 10 is connected to the electronic device and the second serial communication interface 14 is connected to the charging power supply, the intelligent connection line can realize energy transmission.

[0053] The intelligent connection line provided in the embodiments of the present application can include: a first serial communication interface, a first active adapter board, a transmission cable, a second active adapter board, and a second serial communication interface, wherein the first serial communication interface and the second serial communication interface are connected to the first active adapter board and the second active adapter board respectively, the first active adapter board is connected to the second active adapter board through the transmission cable, and the first active adapter board and the second active adapter board are two adapter boards with a voltage reduction function and are mirror-imaged.

For example, the first control module 112 can determine whether the first serial communication interface 10 is a power input end or a power output end according to the first electric signal, if the first serial communication interface 10 is a power input end, the first control module 112 controls the first voltage reduction module 111 to perform the voltage reduction operation matched with the power input end, and if the first serial communication interface 10 is a power output end, the first control module 112 controls the first voltage reduction module 111 to perform the voltage reduction operation matched with the power output end.

The input end of the second control module 132 is connected with the second serial communication interface 14 to detect the second electric signal of the second serial communication interface 14, and the output end of the second control module 132 is connected with the control end of the second voltage reduction module 131. For example, the second control module 132 can determine whether the second serial communication interface 14 is a power input end or a power output end according to the second electric signal, if the second serial communication interface 14 is a power input end, the second control module 132 controls the second voltage reduction module 131 to perform the voltage reduction operation matched with the power input end, and if the second serial communication interface 14 is a power output end, the second control module 132 controls the second voltage reduction module 131 to perform the voltage reduction operation matched with the power output end.
