Air exhaust mode adjusting structure of automobile air conditioner

Abstract

The invention relates to an air exhaust mode adjusting structure of an automobile air conditioner. The air exhaust mode adjusting structure comprises a mode shift disc, an air damper connecting rod, a face blowing air damper and a foot blowing-defrosting air damper, wherein the mode shift disc is rotationally arranged on a casing of an air conditioner assembly; the air damper connecting rod comprises a first air damper connecting rod and a second air damper connecting rod; the first air damper connecting rod is connected with the mode shift disc and the face blowing air damper; the second air damper connecting rod is connected with the mode shift disc and the foot blowing-defrosting air damper. The air exhaust mode adjusting structure has the advantages that by improving the mode shift disc, the air damper connecting rod and the air damper structure, the number of relevant parts is reduced, the difficulty in manufacturing and assembly technology is decreased, the mode air leakage is overcome, and the mode rotary button operation force is reduced.

Description

Technical field [0001] The invention belongs to the technical field of automobile air conditioners, and particularly refers to an air outlet mode adjustment mechanism of automobile air conditioners. Background technique [0002] The car air conditioning system is not only a device for adjusting the air comfort in the car, but also a safety device that gives the car a good driving vision. Due to the different sensitive parts of the human body to hot and cold temperatures (cold air sinks, hot air rises), and to ensure a good driving vision of the driver, the automobile air conditioning system needs to set up face blowing, foot blowing, defrosting and mixed air outlet modes. The air outlet modes of the air-conditioning system are all rotated at different angles by the mode flaps in the air-conditioning assembly shell to form ventilation, semi-ventilation and wind blocking states, so that the entire air-conditioning system forms a variety of different air outlet modes. [0003] Such a...

AI Technical Summary

Problems solved by technology

[0007] When the air outlet mode is switched, the operation force of the mode dial is large, which is not conducive to the reliability of the mechanism. The mode dial needs to drive the linkage of three dampers at the same time, and the movement trajectories of the three dampers are different;

[0008] The mode dial has no locking guide groove, the resilience of the damper sponge itself and the effect of the blower wind will easily cause the damper to fail to overpressure and seal, resulting in air leakage in other modes;

[0009] The change of the windward area and rotation angle of the flat damper causes the fluctuation of the rotation force of the mode dial, that is, the operation force of the controller knob is unstable, which affects the comfort
