When the vehicle air conditioner is working, the air flow inside or outside the cabin first enters the main flow channel 111, and the cooling unit 2 in the main flow channel 111 cools the air flow, and controls the opening of the cold air channel and the hot air channel 113 through the temperature damper group, thereby controlling the ratio of the air flow entering the cold air channel and the hot air channel 113. According to a preset ratio, a part of the cooled air flow enters the mixing chamber 12 through the cold air channel, and the other part passes through the hot air channel 113 and enters the mixing chamber 12 after being heated by the heating unit 3. The hot air flow and the cold air flow are mixed in the mixing chamber 12 and then flow out from multiple air supply ducts 131. Therefore, the temperature difference between each air supply duct 131 is a certain value, and personalized adjustment cannot be achieved. For this purpose, the pipe wall of at least one air supply duct 131 is opposite to the air outlet of the hot air duct 113, and a guide hole 1211 is provided on the pipe wall of the air supply duct 131 opposite to the air outlet of the hot air duct 113, so that part of the hot air flow flowing out of the air outlet of the hot air duct 113 can directly enter the corresponding air supply duct 131 through the guide hole 1211, and the hot air flow entering the air supply duct 131 through the guide hole 1211 and the mixed air flow flowing into the air supply duct 131 from the mixing chamber 12 are mixed again, and then the air flow in the air supply duct 131 provided with the guide hole 1211 can be heated, and the specific amount of hot air flow entering the corresponding air supply duct 131 through the guide hole 1211 is determined by the sliding baffle group.

In this embodiment, the sliding direction of the first baffle 51 intersects with the airflow direction of the guide hole 1211, so the sliding of the first baffle 51 can have a shielding effect on the guide hole 1211, and then the opening of the guide hole 1211 can be adjusted.

[0043] As for how the first driving member drives the first baffle 51 to slide, optionally, the first baffle 51 is slidably matched with the inner wall of the air-conditioning box 1, the first driving member includes a first driving motor and a first driving gear 52, the first baffle 51 is provided with a first rack 511 along its sliding direction, the first driving gear 52 is meshed with the first rack 511, and the first driving motor drives the first driving gear 52 to rotate.

When adjusting the opening of the air outlet of the mixing chamber 12, the first baffle 51 and the second baffle can be driven to move at the same time to coordinately adjust the opening of the air outlet of the mixing chamber 12. The first baffle 51 and the second baffle move in a direction close to each other, and this setting can improve the efficiency of the sliding baffle group in adjusting the opening of the air outlet of the mixing chamber 12. In addition, since one end of the first baffle 51 abuts against the first side wall 121; and thus when one end of the first baffle 51 covers the guide hole 1211, the guide hole 1211 can be sealed.

[0047] Optionally, the second driving member includes a second driving motor and a second driving gear, the second baffle is provided with a second rack along its sliding direction, the second driving gear is meshed with the second rack, and the second driving motor drives the second driving gear to rotate.
