The circuit connecting relation of described backlight lamp operating circuit is：Backlight power supply passes through wire and the second diode 14
It is divided into two branch roads after being connected：First branch road is：Second diode 14 successively with first resistor 15, cold switch backlight 16
It is connected with GND signals；Article 2 branch road is：Second diode 14 successively with second resistance 17, heater switch backlight 18 and
GND signals are connected.Described warm wind request relay 11 is conventional low voltage DC relay.Described cold wind relay 7 is
The pawl relay of low-voltage direct five.
Warm wind operation principle of the present utility model is：There are three kinds of signal source difference in circuit theory diagrams of the present utility model
For：Key, when opening warm wind, need to be placed in KEY-ON by 12V+, ON grades of electricity and backlight power supply, and press leeward gear switch 2, this
When the coil electricity of air blower relay 1, corresponding air blower relay contact switch closure, air blower 3 opens, this air blower after
Electrical equipment 1 ensure that air blower 3 can just be opened only in the case where ON grades are powered.When car key is placed in KEY-ON and opens
When wind gear switch 2 and PTC switches 9, electric automobile VCU warm winds request PIN 13 will receive low level (ground connection), now VCU
It will control to open PTC, make PTC start to heat.This warm wind control system ensure that key is placed in after KEY-ON, when PTC is indicated
When lamp 10 is lighted, warm wind is in running order, when PTC indicator lamps 10 do not work, and warm wind is not at working condition, and ensure that only
Have when opening wind gear switch 2, now air blower 3 is also opened, and could be opened warm wind, so be made automotive air-conditioning system safer,
Be not in that PTC is persistently heated and air blower does not blow the situation of warm wind.
Cold wind operation principle of the present utility model is：It is similar with the operation principle of warm wind, when opening cold wind when looking on the bright side of things, need to ensure
The normal electricity of power supply 12V+ has electricity and key is placed in into KEY-ON.Wind gear switch 2 is now opened, air blower 3 is also opened.Press AC switches
5, electric automobile VCU cold wind request PIN 12 will receive low level (ground connection), and now VCU will control to open compressor, make
Air-conditioning starts refrigeration.This cold wind control system ensures that key is placed in after KEY-ON, when AC indicator lamps 6 are lighted, and cold wind is in work
Make state, when AC indicator lamps 6 do not work, cold wind is not at working condition, and ensure that and only can just be opened when opening air blower 3
Cold wind is opened, so makes automotive air-conditioning system more reasonable, is not in that compressor persistently freezes and feelings that air blower is not blown a cold wind over
Condition.
The utility model cold air interlocks operation principle and circuit safety problem is：System design of the present utility model is cold
The mutual lock control of warm wind, when warm wind and cold wind are switched on, preferentially opens cold wind.
When key is placed in KEY-ON, and warm wind works, press AC switches 5, now AC indicator lamps 6 are lighted, cold wind request after
The coil electricity of electrical equipment 7, the cold wind request normally opened contact adhesive of relay 7.The cold wind request normally opened contact adhesive of relay 7 has cut off warm
Wind asks the loop of the coil of relay 11, makes warm wind ask the contact of relay 11 to disconnect, and PTC indicator lamps 10 are knocked out, and warm wind stops
Work.Now VCU cold wind request PIN 12 have received low level signal, and VCU cold wind request PIN 12 is grounded, and cold wind is opened,
Thus achieve the function of cold air interlocking.
Cold air interlocks specific loop：When car key is placed in KEY-ON and opens wind gear switch 2 and PTC switches 9, electricity
Source 12V+ often by the tip side of air blower relay 1, through the 2 to the first diode of wind gear switch 4, then in turn through PTC open by electricity
9, PTC indicator lamps 10, the warm wind request coil of relay 11 and the cold wind request normally-closed contact of relay 7 are closed, is finally grounded.Now
PTC indicator lamps 10 are lighted, the warm wind request coil electricity of relay 11, corresponding warm wind request relay 11 contact switch closure,
GND signals ask the tip side of relay 11 to ask PIN 13 to VCU warm winds through warm wind, and VCU warm winds request PIN 13 is grounded,
VCU may turn on PTC, make PTC start to heat.Then AC switches 5 are pressed, often electricity is touched power supply 12V+ by air blower relay 1
Point end, through the 2 to the first diode of wind gear switch 4, the line of relay 7 is asked then in turn through AC switches 5, AC indicator lamps 6, cold wind
Circle and pressure switch 8, are finally grounded.Cold wind asks the coil electricity of relay 7, the cold wind request normally opened contact adhesive of relay 7, phase
The lamp of AC indicator lamps 6 answered is lighted, and PTC indicator lamps 10 are knocked out, and warm wind request relay 11 is powered off, and warm wind asks touching for relay 11
Point disconnects, and makes VCU warm winds ask PIN 13 to be disconnected with ground, and warm wind is stopped.Now in foregoing circuit annexation, because cold
Wind request relay 7 normally-closed contact, which disconnects, causes warm wind to ask relay 11 to power off, and above-mentioned annexation disconnects；Cold switch 5
Press, circuit connecting relation now is changed into：Power supply 12V+ by wire successively with air blower relay 1, windshield switch 2,
First diode 4, AC switches 5, AC indicator lamps 6, cold wind request relay 7, pressure switch 8 are connected with GND signals, GND letters
Relay 7 and VCU cold wind request PIN 12 is asked to be connected through cold wind number by wire；Now just complete cold wind and warm wind
Interlocking, cold wind is preferential.
When vehicle is in night flight or navigation pattern, backlight power on, now cold switch backlight 16 or heater switch are carried on the back
Light lamp 18 is lighted, and facilitates driver to be operated.
For the security consideration of circuit, the first diode 4 and the second diode 14 are added within air-conditioning systems, are added
First resistor 15 and second resistance 17.First diode 4 and the second diode 14 ensure that the list of air-conditioner control system circuit
To conduction, it is contemplated that the resistance very little when diode unilateral conduction, first resistor 15 and are added in backlight loop
Two resistance 17 carry out current limliting, it is ensured that the safety of circuit.
