No. 200610123166.8th, China's Mainland patented claim discloses a kind of power-saving circuit and electricity saving method thereof of electronic installation, stop a keypad control unit (keyboard controller under off-mode, KBC) power, its power-saving circuit includes: the first switch, to receive one first voltage; One starting switch, is connected with the first switch, starts or shutdown in order to control electronic installation, and when electronic installation shuts down, starting switch disconnects and the first switch disconnects; And a voltage conversion unit, be connected with the first switch, receive the first voltage and export the second voltage to keypad control unit, when the first switch disconnects, stop providing the second voltage to this keypad control unit, reduce battery power consumption during electronic installation off-mode.
But, though No. 200610123166.8th, China's Mainland patented claim can reduce battery power consumption during electronic installation off-mode, namely, be equivalent to the electricity holding time extending battery, but battery power consumption during electronic installation off-mode can not be avoided completely, if but when the time that electronic installation is in off-mode passes of a specified duration, the electricity in battery also can exhaust, and also may occur the situation that cannot start shooting.
[summary of the invention]
Fundamental purpose of the present invention is the power-saving circuit of the electronic installation providing a kind of no longer power consumption when off-mode.For reaching above-mentioned purpose, the invention provides a kind of power-saving circuit of electronic installation, being connected between battery and main frame; And described power-saving circuit comprises trigger end, described trigger end receives outer triggering signal; And described trigger end is electrically connected switch element, described switch element comprises control end, battery-end and host side, and wherein, described control end is electrically connected trigger end, institute
State battery-end and be electrically connected battery, described host side is electrically connected main frame, and before described trigger end receives trigger pip, is in off-state between battery-end and host side, after trigger end receives trigger pip, between battery-end and host side, transfer conducting state to by off-state.
Compared with prior art, electronic installation of the present invention, before dispatching from the factory, remains open state between battery-end and host side, then battery no longer power consumption in follow-up transport process, even if after experience transport for a long time, battery still keeps original electricity for initial use.Only have when terminal user need try out or use, receive outer triggering signal by trigger end, and make to transfer conducting state to by off-state between battery-end and host side, battery just starts power consumption, thus ensures that battery has enough electricity to use when initial use.
[accompanying drawing explanation]
Fig. 1 is the circuit diagram of the first embodiment of the power-saving circuit of electronic installation of the present invention.
Fig. 2 is the circuit diagram of the second embodiment of the power-saving circuit of electronic installation of the present invention.
[embodiment]
Refer to shown in Fig. 1 and Fig. 2, the power-saving circuit 10 of electronic installation of the present invention is connected between battery 20 and main frame 30, and described power-saving circuit 10 comprises trigger end 11, described trigger end 11 receives outer triggering signal, and wherein, described outer triggering signal can be charging trigger pip, that is, terminal user is charged to electronic installation by charger (not shown), and described trigger end 11 is electrically connected switch element 12, described switch element 12 comprises control end 121, battery-end 122 and host side 123, wherein, described control end 121 is electrically connected trigger end 11, described battery-end 122 is electrically connected battery 20, connection between described battery-end 122 and battery 20 is that plug-in connects, described host side 123 is electrically connected main frame 30, and before described trigger end 11 receives trigger pip, off-state is between battery-end 122 and host side 123, after trigger end 11 receives trigger pip, conducting state is transferred to by off-state between battery-end 122 and host side 123.
In the first embodiment, described switch element 12 is triode thyrister, and wherein, the control end of switch element 12 is the control pole of triode thyrister, the battery-end of switch element 12 is the anode of triode thyrister, and the host side of switch element 12 is the negative electrode of triode thyrister.
In the second embodiment, described switch element 12 is that complementary type triode is to pipe, it comprises PNP triode 124 and NPN triode 125, wherein, the emitter of PNP triode 124 is electrically connected battery 20, the collector of described PNP triode 124 is electrically connected the base stage of trigger end 11 and NPN triode 125, and the base stage of described PNP triode 124 is electrically connected the collector of NPN triode 125, and the emitter of described NPN triode 125 is electrically connected main frame 30.
