Abstract
The invention discloses a display circuit used for an AC indicator lamp of a car air conditioner. The display circuit is characterized in that the display circuit comprises an air blower relay coil, and the negative pole of the air blower relay coil is connected to a pin of a panel connector through a signal line and then is connected to a signal BLOWER ON pin for turning on an air blowing gear through a diode D1; when the air blowing gear is turned on, the air blower relay coil is electrified, and an air blower normally works; and when the air blowing gear is turned off, the air blower relay coil has no power, and the air blower stops working. By the adoption of the structure, when an AC key is pressed and an ignition switch is switched from the ON gear to the CRANK gear for ignition and startup, an AC indicator lamp circuit cannot become a loop due to reversing of the diode D1, and it is ensured that the display circuit can accurately indicate the working states of an air conditioner compressor under various conditions.
Description
Technical field
The present invention relates to the technological improvement of air conditioning for automobiles, particularly to a kind of display for air conditioning for automobiles AC display lamp electricity
Road.
Background technology
Modern automobile, no matter being the truck of passenger car or transport, or electric automobile, often it is equipped with a set of air-conditioning system
System, the purpose of device air conditioning for automobiles is under numerous weathers and driving conditions, provides the in-car of a cool and comfortable to passenger
Environment, prevents the attachment globule or frostwork on glass for vehicle window, by assuring that the driver clearly visual field, to reach safe driving
Purpose.
In air-conditioner control system, simple to operate because of it using manual air conditioner control panel manual air conditioning system, reliable, have
And be widely applied, constitute about the 60% of air conditioning system.Mode tuning knob, temperature is typically had to adjust on manual air conditioner control panel
Section knob, AC button, inner-outer circulation button, mode tuning knob and temperature adjustment knob are controlled respectively by the gear ＆ rack structure of panel
The pattern air door air-out mode (blowing face, foot is blown in the face of blowing, blow foot, blow foot defrosting, defrosting) of air conditioning HVAC assembly processed and blender door
Aperture, reach the purpose controlling air-out direction and leaving air temp.And the temperature of in-car air, humidity regulation then pass through press surface
The AC button of plate, opens what compressor was realized.By the gear of the quantity switch of air knob of guidance panel, adjust the air quantity of aerator
Size, by the inner-outer circulation button of pressing panel, control the forward and reverse of inner-outer circulation motor, such that it is able to for cabin air
Freshness be adjusted.
In manual control panel, general design does not have MCU single-chip microcomputer, the A/C button of panel use, inner-outer circulation button
It is self-locking button, key contacts connect circuit self-locking when depressed, press again, releases self-locking, disconnect.Open compression
Machine request logic be：On the control panel in the case of electricity, when aerator leaves (wind gear switch is placed in non-OFF shelves), by following
The A/C button of plate, control panel sends unlatching compressor request signal, and AC key indicator lamp is bright simultaneously.
But when vehicle switch be in "on" position electromotor not actuated when, air conditioning for automobiles AC switch press rear indicator light
Also can light, cause the misunderstanding of people, affect client's experience.
For the problems referred to above, being provided as AC display lamp provides a kind of new display circuit, can be accurate in all cases
Really indicate the working condition of compressor of air conditioner.
Content of the invention
The technical problem to be solved is to provide a kind of display circuit for air conditioning for automobiles AC display lamp, can
Accurately to indicate the working condition of compressor of air conditioner in all cases.
For reaching above-mentioned purpose, the technical scheme is that, a kind of display circuit for air conditioning for automobiles AC display lamp,
It is characterized in that：Described display circuit includes aerator relay coil negative pole and is connected to drawing of panel connector by holding wire
After foot on be connected to the signal BLOWER ON pin that air blast wind shelves are opened by diode D1；When wind shelves are opened, aerator relay line
Circle energising, aerator normal work, when wind shelves close, aerator relay electric-loss, aerator quits work.
A kind of display circuit for air conditioning for automobiles AC display lamp, because using above-mentioned structure, the present invention is in AC button
Press, when ignition switch is beaten to CRANK shelves ignition trigger by ON shelves, AC indicator light circuit, will not because there being D1 diode reverse
Form loop it is ensured that the present invention can accurately indicate the working condition of compressor of air conditioner in all cases.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description；
Fig. 1 is a kind of circuit diagram of the display circuit for air conditioning for automobiles AC display lamp of the present invention；
Fig. 2 is the circuit diagram of AC display lamp display circuit in prior art.
Specific embodiment
As shown in Fig. 2 existing AC display lamp display circuit is when wind gear switch is in OFF shelves, wind gear switch A5 point is broken with ground
Open, at this moment aerator relay coil negative pole is connected to A5 point, also disconnects, when AC button is pressed, car load ignition switch is by ON shelves
When beating to ignition trigger, AC display lamp is lighted, and when ignition switch is back to ON shelves, AC display lamp goes out.Cause bright the returning of AC display lamp
Road is formed by, and control panel power supply is connected on IGN1, when firing key is beaten to CRANK, IGN1 not power-off, and aerator
Relay coil is connected on car load power supply 15A (ACC), upon initiation, ACC power cut-off, cut-out aerator relay coil electricity
Source, thus cutting off blower duty it is ensured that the electricity supply starter motor of accumulator carries out engine ignition startup, hangs over ACC power supply
On have also CD player and BCM module load, A/C key indicator lamp electric current passes through B1, R1, L1, A/C by being bonded to aerator relay
Device coil negative pole (BLOWER ON B9 point), is connected on ACC line through aerator coil electrode, by the load resistance on ACC line
It is connected to power supply ground, so that AC display lamp is lighted, AC display lamp lights the misunderstanding that can cause people, affect client's experience.
As shown in figure 1, when the present invention thoroughly solves air-conditioning shutdown AC button down state, AC instruction when vehicle ignition starts
The problem that lantern festival is lighted.Aerator relay coil negative pole is connected on the pin of panel connector as a holding wire, it
It is connected on the signal BLOWER ON pin that air blast wind shelves are opened by a diode, when such wind shelves are opened, aerator relay line
Circle energising, aerator normal work, when wind shelves close, aerator relay electric-loss, aerator quits work, and now, AC button is pressed
When lower, when ignition switch is beaten to CRANK shelves ignition trigger by ON shelves, AC indicator light circuit, will not because there being D1 diode reverse
Form loop, thus solve problem above at all.
Above in conjunction with accompanying drawing, the present invention is exemplarily described it is clear that the present invention implements is not subject to aforesaid way
Restriction, as long as employing the various improvement that technical solution of the present invention is carried out or not improved directly applying to other occasions,
All within protection scope of the present invention.
