[0005] The technical solution further defined in the utility model is:

[0006] Furthermore, at least one limit groove is provided on the air inlet duct mounting port, and both the fan mounting end and the air inlet box mounting port are provided with limit protrusions adapted to the limit groove, so as to limit their circumferential movement when the fan mounting end and the air inlet box mounting port are respectively installed on the air inlet duct mounting port.

[0007] Furthermore, the fan mounting end and / or the air inlet box mounting opening are mounted on the air inlet duct mounting opening by means of bolts.

[0008] Furthermore, the fan mounting end and the air inlet box mounting opening are adapted to be connected in the central air inlet duct so that the airflow entering from the air inlet box is transported to the air distribution box through the blower.

[0009] Furthermore, the central air inlet duct is also connected to a rear blowing surface and foot blowing air outlet structure.

[0010] Furthermore, the rear blowing surface foot air outlet structure is located at the lower side of the air distribution box.

[0011] The beneficial effect of the utility model is that the central air inlet duct designed by the utility model is symmetrical about the bisecting plane of the air distribution box, and the blower and the air distribution box are respectively connected to the symmetrical back-facing sides of the central air inlet duct, so that the three-zone central air conditioner can adopt the air distribution box and the central air inlet duct produced in the same batch, and the air distribution box and the central air inlet duct of the left and right rudder air conditioners only need one set of molds to be produced, which meets the requirements of the universalization of the whole vehicle products and can greatly reduce the development cost.

[0016] The three-zone centrally mounted automobile air conditioner provided in this embodiment is as follows: Figure 1 As shown, it includes an air distribution box 1 and a central air inlet duct 2 connected thereto, and the central air inlet duct 2 is symmetrical about the vertical bisecting plane of the air distribution box 1, and air inlet duct mounting openings 21 are opened on the symmetrical back-facing sides (i.e., the left and right sides) of the central air distribution box 2, and the two air inlet duct mounting openings 21 are respectively connected to a blower 3 and an air inlet box 4, the blower 3 is horizontally installed, the blower 3 and the air inlet box 4 are respectively provided with a fan mounting end 31 and an air inlet box mounting opening 41 adapted to the aforementioned air inlet duct mounting openings 21, the central air inlet duct 2 is also connected to a rear blowing surface blowing foot air outlet structure 5, and the rear blowing surface blowing foot air outlet structure 5 is located at the lower side of the air distribution box 1, the left and right rudder air conditioners can adopt the air distribution boxes 1 and the central air inlet duct 2 produced in the same batch, the air distribution boxes 1 and the central air inlet duct 2 of the left and right rudder air conditioners only need one set of molds to be produced, which can realize the universality of the left and right rudder air conditioners to the greatest extent, meet the universality requirements of the whole vehicle products, and at the same time can greatly reduce the development cost.

[0017] For details on the installation mechanism of the blower 3 and the air inlet box 4, see Figure 2Three limiting grooves are provided on the air inlet mounting port 21, and three limiting protrusions adapted to the limiting grooves are provided on the fan mounting end 31 and the air inlet box mounting port 41, so that the fan mounting end 31 and the air inlet box mounting port 41 can limit their circumferential movement when they are respectively installed on the air inlet mounting port 21. The fan mounting end 31 and the air inlet box mounting port 41 are both installed on the air inlet mounting port 21 by bolts, and the bolts specifically penetrate through the limiting protrusions on the fan mounting end 31 and the air inlet box mounting port 41 to be connected to the air inlet mounting port 21.

[0018] In some specific embodiments, the fan mounting end 31 and the air inlet box mounting port 41 are adapted to be connected in the central air inlet duct 2, so that the airflow entering from the air inlet box 4 is transported to the air distribution box 1 through the blower 3, see Figure 3 , which is a schematic diagram of the structure of a three-zone centrally mounted automobile air conditioner after assembly. An air outlet box is also installed on the side of the air distribution box 1. Specifically, in this embodiment, air is extracted by a blower 3, and the air is taken in by the air inlet box 4 and then transported to the air distribution box 1 and the rear blowing surface foot air outlet structure 5 through the central air inlet duct 2.
