Adopt this trigger-type power transfer device, when automobile starting, automatically the ignition switch power supply is connected to vehicle-mounted power consumption equipment, stop simultaneously the automobile storage battery power supply automatically, behind automobile flameout, if enable battery feed when having the people movable into the car automatically, be connected to vehicle-mounted power consumption equipment, can cut off the power supply automatically again after a period of time, guarantee not power shortage of storage battery, more effectively utilize electric energy.
Description of drawings
Fig. 1 represents block diagram of the present utility model;
Fig. 2 represents circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, behind car engine, automobile ignition switch power supply 5 has, after electric current passes through relay J 1, relay J 1 adhesive, the J1 normal opened contact is connected, the J1 normally closed contact is opened, then ignition switch power supply 5 is connected vehicle-mounted power consumption equipment 7, and to its power supply, and automobile storage battery power supply 6 just stops to vehicle-mounted power consumption equipment 7 power supplies.
Behind the automobile flameout, automobile ignition switch power supply 5 dead electricity, the electric current by relay J 1 is zero, and relay J 1 disconnects, and the J1 normal opened contact is opened, and the J1 normally closed contact is connected, and ignition switch power supply 5 stops to vehicle-mounted power consumption equipment 7 power supplies.
If there is this moment the people movable into the car, human body sensing probe or touch switch 8 (described inductive probe can be infrared or microwave) are triggered, electric current passes through R2, R3, voltage will descend, therefore can export a negative pulse Ui, at time-base integrated circuit 3 is under the monostable mode of operation, Ui enters the pin A2 of module I C9, and A2 is 1 pin of putting of module I C9, when Ui≤1/3Vcc, the output pin A3 of module I C9 will export Uo, Uo=1 is a positive rectangular pulse, and this signal is connected to the base stage of NPN triode VT1, at this moment triode VT1 and resistance R 5, R6 constitutes electronic switch, when pulse signal Uo=1, the VT1 conducting, then relay J 2 adhesives, the J2 normal opened contact is therefore closed, because the J1 normally closed contact also is closed at this moment, the automobile storage battery power supply will be to vehicle-mounted electricity consumption power devices.
In the output pin A3 of module I C9 output Uo=1, automobile storage battery power supply 6 charges to capacitor C 1 through resistance R 1 by integrated regulator 4; To the pin A8 of module I C9 power supply, A8 is the power supply pin of module I C9 simultaneously, and integrated regulator 4 is fixedly positive output integrated regulators of three ends, pin A8 and R1, the C1 of the voltage supplying module IC9 that its output pin B3 output is stable.Voltage stabilizing circuit is made of resistance R 4, triode VT2 and capacitor C 2, when voltage reaches 2/3Vcc on the capacitor C 1, be returned to stable state by the circuit upset, the pin A4 of module I C9 is a resetting pin, resetting pin is 0 o'clock, Uo=0, module I C9 discharge pin A7 conducting, capacitor C 1 powered on to press, until trigger next time.
When Uo=0, the output pin A3 pin no-output of module I C9, the base stage pulse-free signal of transistor then, VT1 ends, and the J2 relay electric-loss causes the J2 normal opened contact to disconnect, and the automobile storage battery power supply is no longer to vehicle-mounted electricity consumption power devices.
The pin A1 of module I C9 is a grounding leg, the control pin of the pin A5 of module I C9 and capacitor C 3 composition module IC9.
C1, R1 are timing element, the every triggering, and circuit will be exported the high level of certain hour, and timing T=1.1C1R1 can determine the size of C1, R1 as required.
