Specific embodiment
Below in conjunction with the accompanying drawings, the preferably embodiment of the utility model is described in further detail.
As shown in Figures 1 to 4, this example provides a kind of interface change-over device of USB Type-C, including：Processor module 1,
Logic module 2, signal transmission module 3 and connector modules, the logic module 2 and signal transmission module 3 respectively with processor
Module 1 is connected, and the connector modules are connected respectively with the logic module 2 and signal transmission module 3.
As shown in Figure 1, this example further includes power module 5, the power module 5 respectively with the processor module 1, logic
Module 2, signal transmission module 3 and connector modules are connected.As shown in figures 1 and 3, connector modules described in this example are main
It is used to implement the connection of USB device；The connector modules preferably include USB-A sockets 4 and USB-C sockets 6, the USB-A
Socket 4 is connected respectively with the power module 5 and signal transmission module 3；The USB-C sockets 6 respectively with the power supply mould
Block 5, logic module 2 are connected with signal transmission module 3.
As depicted in figs. 1 and 2, processor module 1 described in this example preferably includes MCU, and at least two USB Type-C
Interface is connected.But at least two USB Type-C interfaces described in this example any one as up going port；The power module 5
Power supply direction is not fixed, by uplink C confessions electricity, without external power supply.
Processor module 1 described in this example supervises the connection of two or more USB Type-C interfaces
It surveys, the USB Type-C interfaces are preferably using USB3.1 Type-C interfaces, if UFP equipment（Uplink jaws equipment or master set
It is standby）Access non-default up going port, and in the case that the up going port given tacit consent to does not have host connection, the processor module 1 is sent
It orders to the signal transmission module 3, and then automatically switches non-default up going port as up going port, default upstream mouth originally is then made
For down going port.
As shown in Figure 1 and Figure 4, logic module 2 described in this example is connected to the collocation channel pin of the connector modules, institute
It states logic module 2 and preferably includes collocation channel logic chip.That is, the logic module 2 preferably passes through FL7001-2F0
Chip（Collocation channel logic chip）It realizes, passes through two collocation channel pins with the connector modules（CC pin）Ditch
It is logical, the access situation and its positive and negative of the C jaws equipments of USB Type-C interfaces are obtained, judgement is UFP equipment（Uplink jaws equipment or
Main equipment）Or DFP equipment（Downlink jaws equipment or slave device）.Wherein, the logic module 2 is also referred to as CC Logic modules, CC
