Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning duct technology, and in particular to an automotive air conditioning duct structure. Background Technology

[0002] As a crucial device for regulating the temperature, humidity, and air quality inside a vehicle, the performance of automotive air conditioning is paramount. The air duct, acting as the "blood vessels" of the air conditioning system, is responsible for delivering hot and cold air and plays a decisive role in its performance. Conventional automotive air conditioning ducts can only be connected one-to-one. This design has a drawback: when attempting one-to-many connections, multiple one-to-one ducts need to be assembled together to complete the duct structure. This results in higher overall costs and reduced assembly efficiency. To address these issues, improvements to the duct structure are necessary. Summary of the Invention
