Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of one of the utility model embodiment;
Fig. 2 is a theory diagram embodiment illustrated in fig. 1;
But Fig. 3 is a charge-discharge circuit schematic diagram embodiment illustrated in fig. 1;
Fig. 4 is two the structural representation of the utility model embodiment;
But Fig. 5 is a charge-discharge circuit schematic diagram embodiment illustrated in fig. 4.
Among the figure: shell 1, button 2, USB interface 3, but charge-discharge circuit 4, rechargeable battery 5, memory 6
Embodiment
Embodiment one:
Fig. 1～Figure 3 shows that one of embodiment of the present utility model, as shown in Figure 1, but comprise shell 1, button 2, USB interface 3 charge-discharge circuits 4, rechargeable battery 5 and remote control circuit, wherein USB interface 3 is arranged on the front end of shell 1, is complementary with the USB interface of institute control electrical equipment self configuration.But charge-discharge circuit 4, rechargeable battery 5 and remote control circuit are arranged in the shell 1, wherein but charge-discharge circuit 4 is the USB charge-discharge circuit, rechargeable battery 5 is lithium electricity chargeable storage and the output that is connected the USB charge-discharge circuit, the remote-control transmitting and the receiving circuit of the aspects such as infrared or ultrasonic wave that the remote control circuit general reference is general.
As shown in Figure 2, present embodiment utilizes the USB interface of electrical equipment self configuration can be the characteristic of the USB peripheral hardware power supply of inserting, the USB interface 3 of remote controller is inserted the USB interface of institute's control electrical equipment self configuration, by the USB charge-discharge circuit rechargeable battery is charged, can realize the charge function of remote controller.
As shown in Figure 3, USB (USB) port is except communication port D+ and D-, two kinds of power supplys can also be provided, the one, the 4.4V～5.25V, the electric current that are provided by the low-power USB port are the power supply of 100MA, the 2nd, and the 4.75V～5.25V, the electric current that are provided by the high power USB port are the power supply of 500MA.Utilize the USB power supply, produce 3.3V and 5V power supply, and be Li
+Battery charges.Its IC1 chip MAX1811 is Li
+The charger of battery.When adopting the USB port power supply to charge the battery, for the low-power USB port, the SEL1 end of IC1 chip is dragged down, its charging current is set at 100mA; For high-power USB port, the SEL1 of IC1 chip should be put height, charging current should be set at 500MA.Similar, SELV put height or put lowly, then the IC1 chip is configured to Li
