Embodiment
As shown in Figure 1, the not charged source of the utility model itself, it is made up of USB input interface 1, many interface conversion circuits 2, many interfaces output device 3, intelligent charge control circuit 4, multifunctional lithium battery Fixing clamp-seat 5, LED illuminating lamp 6, and intelligent charge control circuit 4, LED illuminating lamp 6 are connected on the USB input interface 1 side by side with many interface conversion circuits 2.Described intelligent charge control circuit 4 rear ends connect multifunctional lithium battery Fixing clamp-seat 5, multifunctional lithium battery Fixing clamp-seat 5 can directly be inserted battery and fixing, support polytype cellular li-ion battery seat to fill, multifunctional lithium battery Fixing clamp-seat 5 can adopt battery of mobile phone " omnipotent filling " deck that generally adopts on the present market.Intelligent charge control circuit 4 provides 4.1V for multifunctional lithium battery Fixing clamp-seat 5, maximum 500MA direct current.USB input interface 1 is connected to many interface conversion circuit 2 front ends, many interface conversion circuits 2 rear ends connect many interfaces output device 3, described many interfaces output device 3 comprises USB AM, USB BM, Mini USB 4P BM, Mini USB 5PBM, Mini USB 4P Lock BM interface and IEEE 1394 4PIN retractable USB extended lines for being parallel with the polytype data-interface.But the transmission of many interface conversion circuits 2 and many interfaces output device 3 back printers, scanner, recording disc, digital camera, MP3 player, Digital Video, recording pen, intelligent card reading equipment and data in mobile phone.Wherein: (1) USBAM does and prolongs or signaling transfer point; (2) IEEE 1394 4PIN retractable USB extended line males are used to connect digital camera and photocopier; (3) Mini USB 5P BM is used to connect Card Reader or is used in CD; (4) USB BM is used for connecting scanner and facsimile machine; (5) Mini USB 4P Lock BM is used to connect MP3 and MP4; (6) Mini USB 4P BM is used to connect camera.This connects supports hot plug technology, under the situation of not closing computer power supply, directly inserts USB device, realizes " plug and play ".Described LED illuminating lamp 6 directly is connected USB interface input 1, utilizes multifunctional lithium battery Fixing clamp-seat 5 to be fixed on computer or other places and uses when desk lamp, and the LED lamp adopts the 5V direct current.USB input interface 1 can adopt the retractable USB extended line to be connected on former cellular phone power supplies adapter or other the USB Power Adapter USB interface that is complementary.
As shown in Figure 2, the utility model intelligent charge control circuit 4 adopts intelligent threshold voltage design charging control circuit, after adding power supply and installing battery, the BQ2057 integrated package is at first checked operating voltage VCC, and charger enters park mode when low when operating voltage is crossed; If operating voltage is normal, check that then whether battery temperature is at setting range; If undesired, then enter the temperature fault pattern; Otherwise detect cell voltage VBAT, when cell voltage VBAT was lower than low pressure thresholding V (min), the BQ2057 integrated package carried out precharge with the electric current I of constant current IREG10% to battery.Battery pre-charging or cell voltage VBAT are higher than low pressure thresholding V (min) and when being lower than constant voltage VREG, the BQ2057 integrated package enters the constant current charge state finishing.Control charging current by the pressure drop on the external detection resistance R SNS this moment, and this resistance can be taked high connected mode of supporting the limit, and RSNS is connected between VCC and SNS pin in the flash current detecting, and RSNS is connected between VSS and SNS pin in the current detecting of low limit.When reaching constant voltage VREG, charging voltage enters the constant voltage charge state.In whole working temperature and operating voltage range, the constant voltage precision is higher than scholar 1%, and the BQ2057 integrated package stops charging by BAT and VSS pin monitoring battery voltage when charging current reaches the termination thresholding; Cell voltage is lower than when charging threshold voltage V (RCH) again and begins automatically to charge again.The BQ2057 integrated package is realized continuous monitoring to battery pack temperature by measuring TS and the voltage between the VSS pin, and employing thermistor NTC is as temperature sensor, and by divider resistance temperature detection signal is delivered in the integrated circuit.Whether the BQ2057 integrated package allows charging with the voltage of TS pin and inner V (TS1) and the comparison of V (TS2) threshold voltage with decision.Because outside dividing potential drop and inner threshold voltage all are reference voltage with Vi, can guarantee that like this temperature sensing circuit is not subjected to the influence of fluctuations of working power VCC.When the TS pin is linked VCC or Vss, can forbid the charge function of BQ2057 integrated package.The BQ2057 integrated package can show current charged state by the STAT pin: during charged state, this pin is a high level; When charging was finished, this pin was a low level; In resting state or when temperature fault occurring, this pin presents high impedance status.When connecting monochromatic LED or dual-colored LED outside with the STAT pin, can indicate charged state.
As shown in Figure 3, described many interface conversion circuits adopt USB line concentration expanded function circuit, Bel's gold USB line concentration expanded function circuit as Multi-TT, compatibility issue and transmission bottleneck problem when this circuit will easily solve a plurality of USB1.1 peripheral hardwares and connect, USB1.1 equipment and the mutually noninterfere of USB2.0 equipment, can give full play to superiority bandwidth, realize changeing the multiple interfaces function, support hot plug.The original-pack charger that many interface conversion circuits 2 and many interfaces output device 3 can be the polytype mobile phone to be provided serves as data wire, can not only realize easily that mobile phone directly fills, and not change its charge characteristic.
