Novel passenger car air-conditioning air duct

Abstract

The invention discloses a novel passenger car air-conditioning air duct which comprises a main air duct body, a main air duct body connecting piece and an upper connecting assembly, wherein one end of the main air duct body connecting piece is fixed with the main air duct body, and the other end of the main air duct body connecting piece is spliced with the upper connecting assembly; the other end of the upper connecting assembly is connected with the top of a passenger car carriage. The novel passenger car air-conditioning air duct disclosed by the invention is environmental-friendly, flame-retardant and convenient to install and disassemble, can be maintained and replaced, can be maintained and cleaned by being independently or simultaneously opened totally, is clean in internal environment, difficultly mildews and generates the peculiar smell, is favorable to the health of passengers, has the advantages of easiness and convenience for vehicle renovation and reconstruction, secondary utilization and natural resource waste reduction.

Description

technical field [0001] The invention relates to the field of passenger cars, in particular to a novel passenger car air-conditioning duct which is convenient to install and disassemble. Background technique [0002] In the prior art, passenger cars, especially large passenger cars, are equipped with air-conditioning ducts. The existing air-conditioning ducts are generally made of non-environmental protection and non-flame-retardant materials. Hinge connection, so the following problems generally exist: [0003] 1. It cannot meet the safety requirements of environmental protection and flame retardancy; [0004] 2. After the used manufacturing materials absorb moisture and water, the inside of the air duct is prone to mold and odor, which will cause pollution to the internal environment of the bus and affect the health of passengers; [0005] 3. Due to the limitations of the structural design, the integrated air duct using large sheets of board cannot b...

AI Technical Summary

Problems solved by technology

[0003] 1. It cannot meet the safety requirements of environmental protection and flame retardancy;

[0004] 2. After the used manufacturing materials absorb moisture and water, the inside of the air duct is prone to mold and odor, which will cause pollution to the internal environment of the bus and affect the health of passengers;

[0005] 3. Due to the limitations of the structural design, the integrated air duct with large sheets of board cannot be opened, and the installation and disassembly are time-consuming and laborious. It requires the cooperation of multiple people to complete it. The labor cost is high, the installation and disassembly progress is slow, and the efficiency is low.

The segmented structure connected by hinges can be installed and opened and closed in part or all segments, but it is inconvenient to use other tools to fix and remove screws during installation or installation, and the installation accuracy is not high.
