[0044] Above the heater 15, there are a driver's temperature mixing air door 20 and a passenger's temperature mixing air door (not shown in the figure, located on the right side of the driver's temperature mixing air door 20, and the two are separated by a partition); above the driver's temperature mixing air door 20 is the driver's temperature mixing air area 21; above the passenger's temperature mixing air door is the passenger's temperature mixing air area (not shown in the figure, located on the right side of the driver's temperature mixing air area 21, and the two are separated by a partition); above and at the rear of the driver's temperature mixing air area 21, there are driver's mode air doors 22.

[0045] The air from the evaporator 12 and the air from the heater 15 can both enter the driver's temperature mixing air area 21 through the driver's temperature mixing air door 20, and the air from the evaporator 12 and the air from the heater 15 can both enter the passenger's temperature mixing air area through the passenger's temperature mixing air door; the air in the driver's temperature mixing air area 21 enters the driver's face blowing air outlet 18 after being adjusted by the driver's mode air door 22 above the driver's temperature mixing air area 21; the air in the driver's temperature mixing air area 21 enters the driver's foot blowing air outlet 19 after being adjusted by the driver's mode air door 22 at the rear of the driver's temperature mixing air area 21; the air in the passenger's temperature mixing air area enters the passenger's face blowing air outlet 6 after being adjusted by the passenger's mode air door above the passenger's temperature mixing air area; the air in the passenger's temperature mixing air area enters the passenger's foot blowing air outlet 5 after being adjusted by the passenger's mode air door at the rear of the passenger's temperature mixing air area.

[0046] Below the heater 15, there is a passage for the air from the evaporator 12 (the passage below the air from the evaporator 12, that is, the rear blowing passage). Below and at the rear of the heater 15 (that is, at the intersection of the air from the evaporator 12 and the air from the heater 15 in the passage below the air from the evaporator 12), there is a rear row temperature mixing air door 24. Behind the rear row temperature mixing air door 24 is the rear row temperature mixing air area 25. Behind the rear row temperature mixing air area 25 is the rear row mode air door 26. The rear row mode air door 26 is connected to the rear row face blowing air outlet 3 and the rear row foot blowing air outlet 4. The rear row face blowing air outlet 3 and the rear row foot blowing air outlet 4 both face backward.

[0047] The air discharged from the evaporator 12 and the air discharged from the heater 15 can both enter the rear row temperature mixing area 25 through the rear row temperature mixing air door 24. After the air in the rear row temperature mixing area 25 is adjusted by the rear row mode air door 26, it enters the rear row face blowing air outlet 3 and the rear row foot blowing air outlet 4.

[0048] The opening degree of the driver's seat mode air door 22 is controlled by the driver's seat mode micro motor 1; the opening degree of the co-driver's seat mode air door is controlled by the co-driver's seat mode micro motor 13; the opening degree of the rear row mode air door 26 is controlled by the rear row mode micro motor 17.

[0049] The opening degree of the driver's seat temperature mixing air door 20 is controlled by the driver's seat temperature micro motor 2; the opening degree of the co-driver's seat temperature mixing air door is controlled by the co-driver's seat temperature micro motor 14; the opening degree of the rear row temperature mixing air door 24 is controlled by the rear row temperature micro motor 16.

One evaporator temperature sensor is provided at the air outlet of the evaporator 12. The controller controls the actions of each micro motor according to the temperature value and the air outlet mode set on the air conditioning control panel, as well as the values of each sensor, and then controls the opening degree of each air door.

[0051] For the temperature adjustment of the driver's seat, the implementation method is as follows: The air introduced by the blower first passes through the evaporator for cooling. Part of the air is heated by the heater, and part of the air directly flows into the driver's seat temperature mixing area. The amounts of the two airflows flowing into the driver's seat temperature mixing area are adjusted by the driver's seat temperature mixing air door. The two airflows are mixed in the driver's seat temperature mixing area, and then pass through the driver's seat mode air door, and the mixed air is sent into the vehicle according to the set air outlet mode.

[0052] The temperature adjustment method for the co-driver's seat is the same as that for the driver's seat, and will not be elaborated here.

[0053] For the temperature adjustment of the rear row passenger area, the implementation method is as follows: The air introduced by the blower, after passing through the evaporator, part of the air volume enters the rear blowing channel and directly enters the rear row temperature mixing area, and part passes through the heater. And through the opening degree of the rear row temperature mixing air door, the mixing amounts of cold and warm air are controlled. After being evenly mixed, it then passes through the rear row mode air door, and the mixed air is blown into the rear row passenger area according to the set air outlet mode.

[0054] The passengers in the three zones can respectively adjust the zone temperature through the air conditioning control panel, and then adjust the mixing amounts of cold and warm air in the mixing area, so as to realize the adjustment of the air outlet temperature in different zones.

[0055] Micro-motors, mode disks and corresponding link guiding mechanisms are separately designed for the front-row driver and passenger seats and the rear-row passenger area. Passengers in each area can separately set the air outlet mode. Each micro-motor separately controls the opening and closing of the air dampers in each area according to the currently set air outlet mode, so as to achieve adjustable air outlet modes in three zones.

[0056] A center-mounted three-zone and three-mode heating, ventilation and air conditioning (HVAC) assembly provided in this embodiment can separately adjust the temperatures and modes of the driver's seat, the passenger's seat and the rear-row passengers.
