Detailed Description

As shown in fig. 1, the structure of a blow-out door of an air conditioner for a vehicle according to the present embodiment includes: connect gradually and set up left side on air-conditioning cabinet casing 1 and blow face unit 2, well face unit 3 and the right side and blow face unit 4, well face unit 3 that blows includes: a middle blowing surface left unit 3a and a middle blowing surface right unit 3b which are connected, wherein: the middle blowing surface left unit 3a is connected with the left side blowing surface unit 2, and the middle blowing surface right unit 3b is connected with the right side blowing surface unit 4.

The middle blowing surface unit 3 is connected with the left blowing surface unit 2 and the right blowing surface unit 4 which are respectively positioned at the two sides of the middle blowing surface unit through shaft holes, the cross sections of the three units in the Y direction are consistent, the included angle range of the air door plates at the two sides of the air door shaft is 110-170 degrees, the angle is related to the air flow direction of a blowing surface mode, the angle can be adjusted according to the air quantity distribution proportion of the rear blowing surface, and the larger the air quantity proportion is, the smaller the angle is.

As shown in fig. 2 and 3, the left side blowing surface unit 2 and the right side blowing surface unit 4 have the same structure and are symmetrically arranged, and both include: the damper structure comprises two

straight plates

2b and 2c (taking a left side blowing surface unit as an example) with the lengths of 38mm and 14mm and a shaft 2b (taking a left side blowing surface unit as an example) with the diameter of 15mm, and the included angle of the two
