Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of reserve battery with card-reading function is provided, comprise shell 1, electric core 2, circuit board 3, USB interface 4, with suitable charging output plug 5 and the switch 9 of cellular phone power supplies interface, USB interface 4 is connected with circuit board 3 by electric core 2 with charging output plug 5, USB interface connects Mini SD deck 7 and T-Flash deck 8 by data processor M121, in Mini SD deck 7 and the T-Flash deck 8 Mini SD card 15 and T-Flash card 16 can be installed respectively.Shell 1 comprises loam cake 6, lower cover 10, left side sheet 11, right side sheet 12, upper end cover 13, bottom end cover 14.
As shown in Figure 2, the charging output plug 5 can for the adaptive plug of new SAMSUNG socket.
As shown in Figure 3, charging output plug 5 can be the plug adaptive with the NOKIA socket, and the diameter of one of them plug is 3.5 millimeters, and the diameter of another plug is 2.0 millimeters.
As shown in Figure 4, charging output plug 5 can be the plug adaptive with the SONY socket.
As shown in Figure 5, charging output plug 5 can be the plug adaptive with the SAMSUNG socket.
As shown in Figure 6, charging output plug 5 can also be the plug adaptive with the FOMA socket.
According to the needs of mobile device interface that will be adaptive with it, charging output plug 5 can also be made other shapes.
With reference to Fig. 7, between USB interface 4 and electric core 2, be provided with the step-down constant-current circuit, between charging output plug and electric core, be provided with the voltage increase and current constant circuit.
With reference to Fig. 7, Fig. 8, described step-down constant-current circuit comprises constant-current constant-voltage charging IC (IT4054), resistance R 3, R4, R6, two-color diode D1 and triode Q1 (9014), constant-current constant-voltage charging IC one end is connected with USB interface, the other end is by the pin of resistance R 3 connection two-color diode D1, and constant-current constant-voltage charging IC passes through another pin of resistance R 4, triode Q1, resistance R 6 connection two-color diode D1 successively.
