Description
Technical field
The utility model relates to a kind of coalignment of power supply, a kind of notebook computer car power supply source adaptation of more specifically saying so.
Background technology
At the characteristics and the requirement of the transregional maneuver warfare of field army, on leader's command car, want allocating radio and notebook computer, to finish the task such as in good time commander, transfer of data and satellite fix in motor-driven.Because in remote mobile process, use notebook computer to carry out transfer of data, the battery of himself can only use about 2 hours, standby storage battery also can only use about 10 hours and the cost height, in use can not in time charge, therefore the stable power-supplying that notebook computer works long hours on command car is puzzlement people's a difficult problem always.
Summary of the invention
The purpose of this utility model provides the notebook computer car power supply source adaptation of the notebook computer energy stable power-supplying when working long hours on a kind of command car.
In order to realize above-mentioned purpose; the notebook computer car power supply source adaptation that is provided; its design feature is to be connected to the loop of connecting between the positive output end of automobile storage battery and negative output terminal; this series loop comprises a polarity protection device and the filter that is connected in series with the polarity protection device successively; the output of filter is the positive input terminal of laptop electric power, and the negative input end of laptop electric power is connected with the negative output terminal of automobile storage battery.
In order to simplify circuit structure, above-mentioned polarity protection device is the diode that a forward connects, and promptly the positive pole of diode is connected with the positive output end of automobile storage battery.
In order to strengthen filter effect, above-mentioned filter is a pi filter, also can be the filter of other form.
In order to improve circuit structure, between the positive output end of automobile storage battery and negative output terminal, also be connected to display circuit, this display circuit comprises two light-emitting diodes in parallel, the light-emitting diode that wherein glows oppositely connects, the light-emitting diode forward of green light connects, the negative pole of the light-emitting diode that just glows is connected with the positive output end of automobile storage battery, and the light-emitting diode of green light is anodal to be connected with the positive output end of automobile storage battery.
Above-mentioned notebook computer car power supply source adaptation, in actual applications, its power supply wiring also can carry out wiring with corresponding attaching plug by " cigar lighter " socket of front panel in the car or retread " warning lamp ", " dust catcher " at seat place, the supply socket of " maintenance lamp ".
The operation principle of notebook computer car power supply source adaptation provided by the utility model is: as long as the engine operation on the command car; generator just generates electricity, charges to automobile storage battery; automobile storage battery is remained on the load voltage value; voltage on the automobile storage battery is behind polarity protection device and filter, to the notebook computer stable power-supplying.The effect of polarity protection device is when preventing the power supply wiring reversal connection notebook computer to be caused damage, if the mistake of power supply wiring reversal connection takes place, this moment, the polarity protection device was obstructed, blocking-up is powered to notebook computer, and the lumination of light emitting diode that glows in the display circuit reminds operating personnel to change the polarity of power supply wiring; When the polarity of power supply wiring was correct, notebook computer got electric, the lumination of light emitting diode of green light in this moment display circuit.
Learn by above narration, notebook computer car power supply source adaptation provided by the utility model, its beneficial effect is: 1, simple being suitable for, the circuit structure of this car power supply source adaptation is simple especially, components and parts are few, but very suitable, because the rated voltage numerical value of storage battery 12V normally on the command car, be about 14.5V behind the full charge and the operating voltage of notebook computer is 11V-17.9V, so can directly use the automobile storage battery power supply; 2, can long-time stable power-supplying, as long as the automobile current generator running, automobile storage battery is power shortage not just, just can guarantee the long-time power supply of notebook computer and does not interrupt; 3, be convenient to motor-drivenly, be highly suitable for field army and in motor-driven, use over a long time.
This adaptation is equally applicable to office use on the open-air wireless mobile networking car of notebook computer.
