Novel passenger car air conditioning air channel

Abstract

The invention discloses a passenger car air conditioning air channel comprising an air channel main body, an air channel main body connecting piece, and an upper connecting assembly, wherein one end of the air channel main body connecting piece is fixed on the air channel main body, the other end of the air channel main body connecting piece is connected with the upper connecting assembly in a plugging manner, and the other end of the upper connecting assembly is connected at the top of a passenger car carriage. The air channel is environmentally-friendly, antiflaming, convenient to assemble and disassemble as well as maintain and replace, and can be separately or simultaneously opened for maintenance and cleaning, the internal environment of the air channel is clean, not easy to go mouldy and generate odor, is beneficial to health of passengers, the vehicle can be renewed and transformed simply and conveniently and can be reutilized, so that the natural resource waste is reduced.

Description

technical field [0001] The invention relates to an air duct of a passenger car, in particular to a novel passenger car air-conditioning duct which is convenient for installation and disassembly. 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 be opened. Ins...

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 interior of the air duct is prone to mold and odor, which will pollute 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 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.

In addition, the hinge will rust or loosen after a period of use and lose its original effect

[0006] Therefore, the above two air ducts are inconvenient to install and disassemble for maintenance, cleaning and replacement, resulting in the problem of inconvenient use;

[0007] 4. Vehicle overhaul cannot be reused and time-consuming

[0008] In addition, in the passenger cars in the prior art, the lamps are arranged outside the air duct and exposed to the interior of the vehicle. The light emitted by the lamps is directly irradiated. The cost is high. Firstly, it is inconvenient to install and disassemble the lamp itself. Second, because the lamps are generally installed on the roof of the car, some maintenance of the interior parts of the car needs to be disassembled to cooperate, which will also cause inconvenience.
