[0001] The utility model relates to the technical field of automotive parts, and more specifically, to an automotive air outlet duct assembly. Background Art

[0002] At present, the vehicle air conditioning system has become an indispensable part of modern automobiles. In this system, the defrost duct is one of the crucial components. It is usually located inside the vehicle center console, near the front windshield, and its main function is to direct the hot air flow generated by the air conditioning box onto the front windshield to melt the frost or ice covering the outer side of the glass, and at the same time prevent the glass surface from fogging due to temperature differences.

[0003] Traditional air outlet ducts usually adopt a rigid pipeline structure. However, when the vehicle is running, the vibration of the engine will be transmitted to the duct connection, resulting in abnormal noises in the vehicle body, affecting the noise, vibration, and smoothness (NVH) of the whole vehicle. Summary of the Invention
