DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 3 , a damper mechanism for an automobile air conditioning box, comprising:

[0023] The first partition plate 10 is arranged in the air conditioning box;

[0024] A second partition plate 2 is disposed in the air conditioning box and is spaced just below the first partition plate 10;

[0025] a baffle 3 slidably disposed between the first partition plate 10 and the second partition plate 2;

[0026] Two first driving devices, electrically connected to the vehicle control system, for driving the baffle 3 to move;

[0027] A dehumidification device is arranged in the air conditioning box;

[0028] The conduction device is arranged in the air-conditioning box and is used to connect the circuit of the dehumidification device. When there is airflow in the air-conditioning box, the dehumidification device does not work, and when there is no airflow in the air-conditioning box, the dehumidification device works. In the present invention, the first partition plate 10 and the second partition plate 2 are installed in the air-conditioning box body at intervals, and the opening of the air-conditioning box body is divided into two air supply areas, one area supplies air to the vehicle compartment, and the other area supplies air to the windshield for defrosting. When air supply is not needed, the blower in the air-conditioning box body does not work, and the controller of the automobile control system controls the first driving device on the left to be in working state. The baffle 3 blocks the area supplying air to the windshield. There is no airflow in the air-conditioning box, and the conduction device works to connect the circuit of the dehumidification device, discharge moisture in the air-conditioning box body, and reduce bacteria in the air-conditioning box body. The breeding of odor is reduced, and the gas discharged into the car subsequently carries odor. When the car needs to supply cold air or hot air, the baffle 3 blocks the area supplying air to the windshield, and the cold air or hot air flows into the car. When the windshield needs to be defrosted, the controller controls the first drive device on the left not to work, and controls the first drive device on the right to work. The baffle 3 moves to the left to block the area supplying air to the car, and the wind comes out from the windshield. When the car needs to supply cold air or hot air and the windshield needs to be defrosted, the two first drive devices of the controller both work, the baffle 3 is in the middle position, and the wind is discharged from the two areas.
