Detailed description of the invention
The utility model is described in detail below with reference to embodiment and attached drawing, in which:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is further elucidated below:
As shown in Figure 1, a kind of usb hub 1 for supporting mobile phone fast charge, including computer USB interface 6, power inlet 7,
Several USB output interfaces, and the USB output interface includes USB communication interface and QC fast charge interface, the computer USB connects
Mouth is electrically connected with the USB communication interface, and the power inlet and the QC fast charge interface are electrically connected.This is practical new
Type further includes HUB managing chip.
QC 2.0/QC3.0 charge protocol may be implemented in the utility model, and maximum supports 12V 1.5A power up to 18W
It can be supplied considerably beyond existing similar common product on the market and at the same time having and providing auxiliary for remaining USB data interface
Electricity, and the multiple standards adapter armature that can arrange in pairs or groups carrys out combination product.
The utility model constitutes peripheral hardware by 1 input port USB, 1 power inlet and 4 (can be more) USB outlets
Interface.The input port USB is connected to computer USB interface, and as data transmission purposes, power inlet is connected to QC fast charge function
The standard adapter of energy, as power supply purposes." USB interface 4 " is charging special purpose interface, " usb 1 " " USB interface 2 " " USB
Interface 3 " is used as conventional USB communication interface.
The utility model includes 4, standard USB HUB circuits of a HUB managing chip, 1, DC-DC voltage regulator circuit 5
(5-30V turns 5V) three major parts are constituted, and HUB managing chip connects computer USB interface 6, and passes through several branch USB
Cable is separately connected USB communication interface, and voltage regulator circuit 5 connects USB output interface, and shunt circuit 3 connects power inlet and QC
Fast charge interface 7.
The working principle of the utility model is as follows:
1. hub gets well each hardware coupled as shown；
2. 5V voltage, HUB tube chip are communicated and provided with the managing chip of HUB module after data input port connects computer
Into working condition；
3. power adaptation is connected to input port, 5V voltage is provided for DC-DC voltage regulator circuit and fast charge special purpose interface；
4. " USB interface 4 " is that QC fast charge interface, positive and negative anodes and data port (D+D-) mouth and power inlet are positive and negative
Pole and data port (D+D-) connection, are equivalent to direct-connected, the delivery outlet of power supply adaptor are extended to " USB interface 4 "；
5. the positive and negative anodes of " USB interface 4 " are connected in parallel to " voltage regulator circuit ", it is by pressure stabilizing output 5V voltage to " HUB circuit "
The circuit of HUB provides 5V auxiliary power supply；
6.HUB interface 1-3 is in the state for waiting work.Insertion USB flash disk or mobile hard disk can be read and write with dataphone
Deng operation；
7. " USB interface 4 " connection has the mobile phone/equipment of QC fast charge agreement, due to " USB interface 4 " D+D- of the design
The D+D- direct port connection of PORT COM and power input port, so charging can be realized；
It is electrically charged the D+D- port communication of equipment Yu QC power adaptation, and QC agreement of shaking hands；The transmission of QC charging equipment is asked
It asks, request power supply adaptor increases output power (improving voltage/raising electric current)；The agreement of QC adapter is electrically charged asking for equipment
It asks,
And voltage is improved, electric current is increased.Mobile phone enters QC fast charge at this time, thus adaptor voltages output 5-12V it
Between change (the conventional operating condition of QC agreement, be not described) charging equipment enter fast charge state.
8. since this programme possesses a DC-DC voltage regulator circuit, no matter which kind of between 5-12V QC power supply adaptor provide
Voltage, the output 5V voltage that voltage regulator circuit can be stable provides constant 5V auxiliary power supply to " HUB circuit ", to ensure USB
The other equipment electric current that HUB is connected is sufficient, guarantees that USB HUB simultaneously transport by stablizing for multiple hard disk carries (other USB devices)
Row.
9. simultaneously because the variable voltage that power supply adaptor exports under QC fast charge mode is directly connected to mobile phone port, thus
It will not influence the QC fast charge mode state of charging equipment.
10. due to standard QC charger have current limiting pressure-limiting safety, perfect defencive function, so no matter " HUB circuit "
How many electric current are shunted, in the current-limiting protection strategy being adapted to both limited by QC, mostly and few according to the equipment of HUB connection, power is big
With it is small, can automatically distribute electric current to other HUB delivery outlets.Safe and efficient, adapter performance utilization rate increases significantly, flexibly
