Integrated structure of air duct and internally-installed middle top plate

Abstract

The invention discloses an integrated structure of an air duct and an internally-installed middle top plate. An upper layer air conditioner air inlet plate and a lower air conditioner air outlet plate are of arc-shaped structures. A gap is formed between the upper layer air conditioner air inlet plate and the lower air conditioner air outlet plate. A rubber sealing strip and an aluminium alloy installing bracket are arranged in the position, connected with the edge of a vehicle roof, of the upper layer air conditioner air inlet plate. Compared with the prior art, according to the integrated structure of the air duct and the internally-installed middle top plate, the internally-installed middle top plate of a vehicle is turned into an air duct bottom plate, the functions of the air conditioner air duct and the internally-installed middle top plate are integrated, two parts are combined into one part, the vehicle inner space is greatly saved, weight is reduced, the structure is mainly composed of whole glass steel, the aluminium alloy installing bracket and the rubber sealing strip, the integration level is high, and the maintainability is high.

Description

technical field [0001] The invention relates to an integrated structure of an air duct and an interior middle roof, which belongs to the field of design of interior structures applied to rail transit vehicles. Background technique [0002] In the existing rail transit vehicles, the air-conditioning air duct and the interior middle roof are separate structures that are independent of each other, and each realizes its function, not as an integral part of the air duct, and does not have the function of the air duct floor; the air duct is also independent, not It has the function of a mid-top plate, occupies a large space, and cannot well meet the weight reduction requirements. The suspended air-rail vehicle is a new type of rail vehicle that has just started in China. It is restricted by the space structure of the vehicle and cannot use an independent air duct and a built-in mid-roof structure. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the prese...

Problems solved by technology

[0002] In the existing rail transit vehicles, the air-conditioning air duct and the roof of the interior decoration are separate structures independent of each other, and each realizes its function. It is not an integral part of the air duct and does not have the function of the air duct bottom plate; the air duct is also independent and does not It has the function of the middle roof, takes up a lot of space, and cannot meet the weight reduction requirements well

The suspended empty rail vehicle is a new type of rail vehicle that has just started in China. Due to the constraints of the space structure of the vehicle, it is impossible to use an independent air duct and a built-in mid-roof structure.
