The utility model has a reasonable structure. The design can enable the upper air intake and the right-end air intake to be opened at the same time, thereby increasing the air intake volume of the air intake and meeting the heating and cooling adjustment functions of the automobile air conditioner. The right-end air intake can also be closed when driving on a flooded road to prevent water from entering the air intake.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: an automobile air-conditioning air intake structure, comprising a mounting base, an air intake duct, a funnel air inlet, a three-way duct, a one-way valve, an electric push rod and a sealing plate, an air intake housing is fixed to the upper end surface of the mounting base, a first connecting housing is welded to the right end surface of the air intake housing, a connecting flange is welded to the right end surface of the first connecting housing, and a second connecting housing is installed to the right end surface of the connecting flange;

[0006] A funnel air inlet is installed on the upper end face of the second connecting shell, a three-way pipe is installed inside the first connecting shell and its upper end face is sealed and connected to the funnel air inlet, an air inlet duct is installed on the right end face of the three-way pipe and extends out of the outside of the second connecting shell, a one-way valve is arranged on the outside of the annular surface of the air inlet duct, an electric push rod is fixed on the upper end face inside the second connecting shell, a sealing plate is fixed on the lower end face of the electric push rod and extends into the inside of the air inlet duct.

[0007] Furthermore, the mounting base is fixed by fastening bolts.

[0008] Furthermore, a sealing gasket is provided between the air inlet duct and the second connecting shell, and a sealing gasket is provided between the funnel air inlet and the three-way duct.

[0009] Furthermore, a sealing gasket is provided between the one-way valve and the three-way pipe, and a sealing gasket is provided between the one-way valve and the air inlet pipe.

[0010] Furthermore, a sealing groove is provided inside the air inlet duct, the specification of the sealing groove matches the specification of the sealing plate, and the two can be fitted and connected.

[0011] Furthermore, the funnel air inlet, the one-way valve, the air inlet duct, the electric push rod and the sealing plate constitute an adjustable air inlet assembly.

[0012] Furthermore, the upper half of the funnel air inlet is configured as a fan-shaped structure.

[0013] The beneficial effects of the utility model: the utility model is an automobile air-conditioning air intake structure. Since the utility model adds an air intake duct, a funnel air inlet, a three-way pipe, a one-way valve, an electric push rod and a sealing plate, the design can make the upper air intake and the right-end air intake open at the same time, increase the air intake volume of the air intake, meet the heating and cooling adjustment function of the automobile air-conditioning, and can close the right-end air intake when crossing a flooded section to prevent water from entering the air intake. This solves the problem that the air intake of the original automobile air-conditioning air intake structure is always located above the waterproof air intake box, and the airflow above cannot be introduced into the air intake, thereby reducing the air intake volume of the air conditioner and affecting the heating and cooling adjustment function of the air conditioner.
