Air intake device of automobile air-conditioning system and automobile air-conditioning system

Abstract

The invention provides an air inlet device for an automotive air-conditioning system. The air inlet device for the automotive air-conditioning system comprises a main body part, an air door and a driving rod. The main body part comprises a hollow shell. The shell is provided with an air outlet, and an inner circulating air window and an outer circulating air window are formed in the two opposite sides of the shell correspondingly. Limiting grooves are formed in the main body part. Limiting shafts are arranged on the air door. The two ends of each limiting shaft are rotatably and slidably mounted in the limiting grooves, so that the air door is movably mounted in the main body part through the limiting shafts, and the air door is located between the side, where the inner circulating air window is formed, of the main body part and the side, where the outer circulating air window is formed, of the main body part. When the air door moves in the main body part, the edge, facing the outer side of the air outlet, of the air door never exceeds the circumferential edge of the air outlet to protrude out of the air outlet.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile air-conditioning system and an air inlet device thereof. Background technique [0002] The air circulation mode of the automobile air conditioning system generally includes the internal circulation mode and the external circulation mode. The internal circulation mode refers to the cooling or heating process that only circulates the air inside the car cabin, while the external circulation mode refers to the external environment. The air is discharged into the interior of the car cabin after being refrigerated or heated. [0003] Nowadays, many new car models, especially electric vehicles, may require the car air-conditioning system to open both internal circulation and external circulation air circulation modes at the same time in some cases (for example, when electric vehicles use internal circulation refrigeration, it may be necessary to Turn on the outer circulation to...

AI Technical Summary

Problems solved by technology

However, the structure of the air mixing device in the existing automotive air conditioning system is generally more complicated, and in the process of adjusting the mixing ratio of the internal and external circulating airflow, in order to change the air duct inside the air mixing device, it is often necessary to compare the mechanical components of the air mixing device. Complicated adjustment actions are not only cumbersome to operate, but also often form redundant wind resistance structures when adjusting the positional relationship of these mechanical components, blocking the smooth passage of airflow; this not only reduces the working efficiency of the air conditioning system, but also makes it difficult to mix the internal and external circulating airflow The ratio is adjusted linearly, which affects the adjustment accuracy of the air outlet temperature of the air conditioning system
