Relationship；Wherein, at least one in first interface 120 and second interface 130 is Type-C interface.
Microprocessor 140 specifically further includes 140 ontology of microprocessor and corresponding periphery electricity for controlling connection switching
Road.Microprocessor 140 is PLC (Programmable Logic Controller, programmable logic controller (PLC)) or single-chip microcontroller.
First interface 120 and second interface 130 are Type-C interface；Or in first interface 120 and second interface 130 one be
Type-C interface, another is Micro USB interface, USB interface or Lightning interface.In use process, first interface
120 and second interface 130 one of them as host interface, another is as slave interface.In addition, passing through microprocessor 140
Control switching, can make the master-slave relationship of first interface 120 and second interface 130 exchange.
Working principle explanation: slave interface is Type-C interface, and host interface is for Micro USB interface.
Connector 100 when being worked with the state of default, i.e., access Type-C interface equipment as slave (if
When being both Type-C interface, one of them is defaulted for host interface, another is as slave interface), host can be passed through
Interface transmits data with external host communication or charges.In addition, entering slave mould in the equipment with Type-C interface
When formula, it may also select whether to charge to it by power supply module 110.It avoids to exist with Type-C interface equipment in this way
Electric energy when slave mode to consume host.That is when the state of default is worked, it also can use connector 100
Power supply module 110 charge to slave.
When microprocessor 140 receives switching signal, microprocessor 140 is acted according to scheduled switching route, is cut at this time
The master-slave relationship of the equipment of first interface 120 and the connection of second interface 130 is changed, the equipment of Type-C interface is as host, host
Data communication is carried out with the slave being connected on slave interface, the electric energy of slave interface is supplied by power supply module 110 at this time.
The switching of master-slave relationship is actually existed using the CC pin of the pin control Type-C interface of microprocessor 140:
The CC pin of Type-C interface is grounded, and the resistance and CC pin and VCC pin for the 5.1K that connects are shorted, while being connected one
Switch between the resistance of 51K.Such as (such as relay) can be switched in the resistance of one 5.1K of CC pin serial connection and a switching,
Switch the movable contact connecting resistance of switch, normally-closed contact and VCC pin are shorted, normally opened contact ground connection.
Referring to Fig. 2, power supply module 110 includes energy-storage battery 111, charge-discharge circuit in a wherein embodiment
112 and voltage conversion circuit 113, one end of charge-discharge circuit 112 connect with energy-storage battery 111, charge-discharge circuit 112 it is another
One end is connect with first interface 120 and/or second interface 130, and voltage conversion circuit 113 is connected to the another of charge-discharge circuit 112
Between one end and microprocessor 140.Further, power supply module 110 further includes power interface 114, power interface 114 and voltage
Conversion circuit 113 connects, and connects with first interface 120 and/or second interface 130.In general, when charge-discharge circuit 112 discharges
The charge power supply voltage provided to host or slave is generally 5V, and charge power supply is supplied to by the conversion of voltage conversion circuit 113
The voltage for the work energy that the other components such as microcontroller 140 use is generally 3.3V；And power interface 114, first interface 120
Or the supply voltage that second interface 130 accesses is generally 5V, it can be seen that, connector 100 can be supplied with energy-storage battery 111
Electricity also can be directly used external power supply and be powered.And battery can use power interface 114 and pass through charge-discharge circuit 112
It charges, first interface 120 or second interface 130 also can be used and charged by charge-discharge circuit 112.
Referring to Fig. 3, connector 100 further includes connecting with microprocessor 140, in a wherein embodiment to have
The communication module 150 of line or the wirelessly electricity of outgoing power supply module 110.If it can be seen that power supply module 110 using
For battery as power supply, microprocessor 140 can acquire the remaining capacity information of battery, with wired or wirelessly pass
Output comes.Specifically, communication module 150 can be bluetooth module, Zigbee module or WIFI module, opens and can be cable port
Or USB interface.
It is further possible to receive external signal by communication module 150.So in one embodiment, for controlling
The switching signal for making the first electronic equipment 200 and the second electronic equipment 300 switching master-slave relationship can be received with communication module 150.
In another embodiment, connector 100 further includes the button 160 connecting with microprocessor 140, and button 160 is cut for inputting
Change signal.In addition, above-mentioned master-slave equipment, i.e. the first electronic equipment 200 and the second electronic equipment 300 can be mobile terminal,
Such as smart phone, plate or notebook, storage device, such as USB flash disk, mobile hard disk etc. can also be.
In one example, when defaulting working condition, power supply module 110 are being powered to microprocessor 140, microprocessor
140, which also work, waits wake-up in standby mode, and microprocessor 140 is waken up when button 160 is pressed, and controls related circuit
It is connected with host with slave, while powers for slave.Slave starts cooperation host supplying power
System returns to original state again, achievees the purpose that switching.
The connector 100 of above-mentioned Type-C interface passes through to the master-slave swap at present to the equipment with Type-C interface
Route improves, and increases power supply module 110, does not need the equipment with Type-C interface also when in use externally
Power supply, extend equipment uses the time, reduces the fever in use process.Solution Type-C equipment is used as host and is needed
It to power to slave, and shorten the problem of host is using time and increase calorific value, give slave to supply by independent power supply circuit
Electricity avoids maintaining slave operation by host supplying power.Power supply circuit carries out control on-off by main control chip simultaneously, is guaranteeing not shadow
Under the premise of sound is functional, the continuation of the journey of host equipment is increased, the fever of host equipment is alleviated.
By changing to the power supply mode of slave, reduce slave to the electric quantity consumption of host, with Huawei's mate8 smart phone
For, the battery capacity of mobile phone itself is 4000mAh, normal voltage 3.7v, if external slave devices power is 0.5W, that
The electricity of mobile phone 135mAh is consumed per hour.If being powered using power supply module to peripheral module, the electricity of saving
Can be used to extending cell phone uses the time, reduces fever.
