Abstract
The invention relates to a portable concentrator with a USB (Universal Serial Bus). A mobile power supply and the USB concentrator are daily indispensable matching products of mobile equipment such as a mobile phone. The conventional mobile power supply and the USB concentrator are two independent products with single function and are needed to be purchased, stored and used respectively, thereby being extremely inconvenient. The portable concentrator with the USB comprises a shell, wherein a USB uplink interface and a USB downlink interface are arranged on the shell; a HUB and a power management chip, a discharge management chip, a USB downlink interface discharge management chip, a boost chip, a charging chip and a battery are arranged in the shell. The invention provides a product in which the mobile power supply and the USB concentrator are combined, and an internal storage battery can simultaneously provide a power supply for multiple mobile devices; besides, convenient and rapid experience is provided for the user, and the defect that the two products, namely the mobile power supply and the USB concentrator, have single function, is overcome..
Description
Technical field
The present invention relates to a kind of 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 portable with usb hub.
For solving the problems of the technologies described above, basis is portable comprises shell with usb hub, it is characterized in that: described shell is provided with USB upstream Interface, USB downstream interface, in shell, be 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 battery.
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 battery, and described battery connects 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 internal cell charges by charging chip, by power supply, boosted after chip changes inner cell 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 cell voltage and supplies with HUB and power management chip simultaneously.
The portable product that provides a kind of portable power source to combine with usb hub with usb hub of the present invention, it utilizes internal battery to 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, to the present invention is portable, with usb hub, be described further:
Fig. 1 is this portable internal structure connection diagram (shell is not shown) with usb hub.
In figure: 1-USB upstream Interface, 2-USB downstream interface, 3-HUB and power management chip, 4-USB downstream interface electric discharge managing chip, 5-boost chip, 6-charging chip, 7-and battery.
Embodiment
As shown in Figure 1, basis is portable comprises that with usb hub described shell is provided with USB upstream Interface 1, USB downstream interface 2, is provided with HUB and power management chip 3, electric discharge managing chip 4, USB downstream interface electric discharge managing chip 5, the chip 6 that boosts, charging chip 7 and battery 8 in shell.Described USB upstream Interface 1 connects HUB and power management chip 3, and described HUB and power management chip 3 connect some USB downstream interfaces 2.Described USB upstream Interface 1 connects charging chip 7, and described charging chip 7 connects batteries 8, and described battery 8 connects the chip 7 that boosts, described in the chip 7 that boosts connect some USB downstream interfaces electric discharge managing chips 5.Described USB downstream interface 2 connects one to one with described USB downstream interface electric discharge managing chip 5.Described USB downstream interface electric discharge managing chip 5 is all connected with HUB and power management chip 3.
