Abstract
The invention relates to a novel portable USB (universal serial bus) concentrator. Mobile power supplies and USB concentrators are matched products necessary for the daily use of mobile devices such as mobile phones, and conventional mobile power supplies and USB concentrators are independent products, and are required to be bought, stored and used respectively, so that great inconvenience is caused. The novel portable USB concentrator comprises a shell, wherein an uplink USB interface and downlink USB interfaces are arranged in the shell; a HUB and power management chip, a discharge management chip, downlink USB interface discharge management chips, a boosting chip, a charging chip and an AC-DC (alternating current-direct current) converter and safety plug are arranged in the shell. The novel portable USB concentrator is a product combining a mobile power supply and a USB concentrator, and the AC-DC converter and safety plug in the concentrator can be used for simultaneously providing power for a plurality of mobile devices, so that convenient and rapid experiences are provided for users, and the shortcoming of being undiversified in function of the two products, namely the mobile power supply and the USB concentrator, is overcome.
Description
Technical field
The present invention relates to a kind of novel portable with usb hub.
Background technology
Portable power source and USB hub are all the daily requisite auxiliary products of the mobile devices such as mobile phone, and existing portable power source and USB hub are two stand-alone products with simple function, must buy respectively, deposit and use, very inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, provides a kind of novel portable with usb hub.
For solving the problems of the technologies described above, this novel portable comprises shell with usb hub, described shell is provided with USB upstream Interface, USB downstream interface, is provided with HUB and power management chip, electric discharge managing chip, USB downstream interface electric discharge managing chip, the chip that boosts, charging chip and AC-DC converter and safety plug in shell.
As optimization, described USB upstream Interface connects HUB and power management chip, and described HUB and power management chip connect some USB downstream interfaces.
As optimization, described USB upstream Interface connects charging chip, and described charging chip connects AC-DC converter and safety plug, and described AC-DC converter and safety plug connect the chip that boosts, described in the chip that boosts connect some USB downstream interfaces electric discharge managing chips.
As optimization, described USB downstream interface and described USB downstream interface electric discharge managing chip connect one to one.
As optimization, described USB downstream interface electric discharge managing chip is all connected with HUB and power management chip.
Principle:
1, usb hub function-USB upstream Interface input usb data expands a plurality of USB downstream interfaces by HUB chip, realizes the function that multiple USB device is used simultaneously.
2, portable power source function-USB upstream Interface input power is that inner AC-DC converter and safety plug charge by charging chip, by power supply, boosted after chip changes inner AC-DC converter and safety plug voltage again, by power management chip, utilize USB downstream interface electric discharge managing chip by a plurality of equipment enforcement power supplies such as USB downstream interface are mobile phone again, when utilizing USB downstream interface electric discharge management chip detection to send instruction when USB downstream interface has equipment access, power management chip carries out electric discharge to USB downstream interface electric discharge managing chip, while equipment being detected, USB downstream interface is not closed, no current output, power supply boosts after chip is changed inner AC-DC converter and safety plug voltage and supplies with HUB and power management chip simultaneously.
The product that novel portable of the present invention provides a kind of portable power source to combine with usb hub with usb hub, it utilizes inside to hold AC-DC converter and safety plug and can be a plurality of mobile devices simultaneously power supply is provided, the experience of more convenient and quicker is provided for user simultaneously, has solved two single defects of product function of portable power source and usb hub.
