Embodiment Construction
[0018] like Figure 1 ~ Figure 3 The shown air inlet assembly of an automobile air conditioner includes an upper air inlet housing 1, a lower air inlet housing 2, and an internal and external circulation damper 3. The upper air inlet housing 1 and the lower air inlet housing 2 are connected to form an air inlet housing. The tuyere assembly also includes a stepping motor 4 that drives the internal and external circulation air door 3 to rotate axially, so that the structure can switch the state of internal and external circulation. The air inlet housing is provided with a universal device mechanism for stepping motors. The housing 1 of the upper air inlet is provided with an outer circulation air inlet and an inner circulation air inlet.
[0019] The upper air inlet housing 1 and the lower air inlet housing 2 are assembled and connected by sealing tongue and groove and screws. The two sides of the lower air inlet housing 2 are respectively provided with arc-shaped bosses, and ...

The invention discloses an automotive air conditioner air inlet assembly. The automotive air conditioner air inlet assembly comprises an upper air inlet shell, a lower air inlet shell and an internaland external circulation air door, wherein the upper air inlet shell and the lower air inlet shell are connected to form an air inlet shell. The air inlet assembly further comprises a stepping motor driving the internal and external circulation air door to axially rotate, and the upper air inlet shell is provided with an external circulation air inlet and an internal circulation air inlet. The automotive air conditioner air inlet assembly has the advantages that 1, production personnel perform assembly quickly, the operation is simple, and only one-time shaft hole assembly is needed; 2, an automotive air conditioner air inlet structure is simple in transmission process, simple in structure and high in strength, and has universality; 3, the problem of poor leakproofness caused by the demoulding angle is solved, the leakproofness is greatly improved, and the leakproofness is good.
Description
technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an air inlet assembly of an automobile air conditioner and an installation method thereof. Background technique [0002] The air inlet of the automobile air conditioner is generally assembled from the left, the air inlet shell and the inner and outer circulation dampers, so the production personnel have two shaft hole assemblies during the assembly process. At the same time, the housings of the left and right air inlets will have opposite draft angles in order to realize demoulding in the injection mold, and the sealing performance of the housings after assembly is relatively poor. Therefore, it is necessary to develop a structure to improve assembly efficiency and eliminate the problem of poor sealing caused by the demoulding angle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile ai...
