Embodiment
As shown in Figure 1, in the embodiment of a kind of battery of mobile phone expansion power supply of the present invention and charging device, described device comprises: the booster circuit 6 that battery connector and an end are connected with battery connector, and the other end of booster circuit 6 connects mobile phone to be charged; Described battery connector comprises: panel 3, the battery tray 5 that is fixedly connected with panel 3 through spring 4, two both positive and negative polarity Metal Contact formula shell fragments 1 and 2 controlling through two poles that are arranged on the panel 3; One end of two poles is fixed on a bit on the panel 3; Two poles become V-type, can horizontally slip as the clock and watch pointer respectively, regulate swing position respectively; So that metal clips can be aimed at the pin both positive and negative polarity of contact battery; The T type that is shaped as of described Metal Contact formula shell fragment, no matter the both positive and negative polarity pin is provided in a side of the upper surface or the side of battery, can with its good contact.After the clamping of shell fragment both positive and negative polarity aligning battery plus-negative plate, the power supply of external connection battery just passes through the transmission line of metal clips input and inside in power supply and charging circuit 6, inputs to the mobile phone use through data wire and plug 8 at last.Described battery tray 5 be used for support metal contact shell fragment 1 and 2 with place battery 7.Described booster circuit 6 is the DC/DC booster circuit.
As shown in Figure 2, when battery put into block after, this moment, VB+ just had voltage: when switch J4 switched to a1, the x of switch, a1 were communicated with, power supply just supplies mobile phones to use through data wire and plug 8 outputs, be equivalent to this moment mobile phone at this moment external a battery; When switch J4 switched to b1, the x of switch, b1 were communicated with, and this moment, voltage just inputed to the DC/DC booster circuit, output 5V voltage, and this voltage inputs to cell-phone charging through plug; J4 is the single-pole double-throw switch (SPDT) that is used to switch among the figure; U3 is for switching chip; The interface of plug for matching with the mobile phone socket, present case adopts the most widely used 5PIN USB, in the time of promptly will be for this function of certain mobile phone development; Only need mix with the same joint of charger of institute exploitation mobile phone for this instrument and get final product, T1 is an electrostatic protection device among the figure.
As shown in Figure 3, when external power supply inserts the back: when Fig. 3 mobile phone circuit switch J2 switched to a2, the external power supply tool switch J4 of this moment cooperation switched to b1, the gear of promptly directly supplying power, the convenient outside powered battery of using of mobile phone this moment.The battery electric quantity of mobile phone self uses up, thus in order to improve energy utilization ratio, can pull up the battery that mobile phone does not have electricity, in order to avoid in external connection battery power supply time, irritates electricity for again first wife's battery of mobile phone and causes waste.
When Fig. 3 mobile phone circuit switch J2 switched to b2, it was the charge function gear that the external power supply tool switch J4 of this moment switches to a1, and external connection battery just begins first wife's battery is begun charging; J1 is the mobile phone jack interface among the figure, and J2 is the function diverter switch, and U1-B is the CPU charge management circuit, and U2 is the charge protection chip, and R3 gets the 0.2ohm precision resistance, is used for the calculating of charging current.
In sum, as those of ordinary skill is scrutable in the art, described in this specification is a preferred embodiment of the present invention, and all changes of being made under this invention's idea or modification all should be in claim protection ranges of the present invention.
