Air door adjusting structure, air outlet assembly and automobile air conditioning system

Abstract

The invention provides an air door adjusting structure, an air outlet assembly and an automobile air conditioning system. In the air door adjusting structure, the edge of one side of a first blade of an air door is connected with a first semi-axle of a center axle through a first sleeve; the edge of one side of a second blade of the air door is fixedly connected with a second sleeve which is arranged on a second semi-axle of the center axle in a sleeved mode; a first half bevel gear is fixedly arranged on the circumferential surface of the first sleeve through the inner side of the first half bevel gear; a second half bevel gear is fixedly arranged on the circumferential surface of the second sleeve through the inner side of the second half bevel gear; a bevel gear is engaged with the first half bevel gear and the second half bevel gear respectively; the bevel gear is engaged with the first half bevel gear and the second half bevel gear all the time in a process that the angle between the first blade and the second blade is increased from zero to a set maximum angle. According to the air door adjusting structure, the air outlet assembly and the automobile air conditioning system, a device with the air door adjusting device is smooth in operation without vibration or abnormal sound; the arrangement of transmission mechanisms is compact; transmission parts are fewer, so that mould costs and product costs are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration, in particular to an air door adjustment structure, an air outlet assembly and an automobile air conditioning system. Background technique [0002] At present, the opening and closing functions of the damper of the air outlet of the automobile air conditioner are usually realized by a linkage mechanism. Since the linkage mechanism has many connected parts, the movement process of the components is not stable, and it is easy to generate abnormal vibrations; and the layout of the linkage mechanism requires a large space. , It is a huge challenge for the current instrument panel layout with increasingly high integration and functional requirements; there are many linkage components, and the molds and finished products are also high. [0003] figure 1 It shows a structural schematic diagram of the air outlet of the air conditioner that realizes the opening and closing of the da...

AI Technical Summary

Problems solved by technology

[0004] The defect of the air outlet structure of the automobile air conditioner in the above-mentioned prior art is that: the existing air outlet structure with a linkage mechanism has many connecting parts, the movement process of the components is not stable, and vibration and abnormal noise are likely to occur; and the layout of the linkage mechanism requires Larger space; more linkage components, higher mold and product costs
