Referring to fig. 1, the duct assembly 100 is disposed at both sides of the roof of the vehicle and extends in the front-rear direction. The air duct assembly 100 includes an air duct board 10 and an access panel 20. The duct board 10 has a concave structure, is mounted on the inner wall 80 of the vehicle roof in a covering manner along the front-rear direction, and forms a main air chamber 30 extending along the front-rear direction together with the inner wall 80 of the vehicle roof. The maintenance hanging plate 20 is arranged below the air duct plate 10, the upper side of the maintenance hanging plate is connected to the air duct plate 10, and the lower side of the maintenance hanging plate is connected to the vehicle inner side wall 90; the maintenance hanging plate 20, the vehicle inner wall 200 and the air duct plate 10 are enclosed together to form a structural cavity 40 extending in the same direction as the main air cavity 30, the main air cavity 30 is used for conveying air, and the structural cavity 40 is used for accommodating arrangement pipelines.

Specifically, the duct board 10 is mounted on the roof inner wall 80 in a concave structure shape, and a duct space extending in a length direction, that is, a main air chamber 30, is formed inside the duct board 10 for conveying cool and warm air in a front-rear direction in the vehicle. An access panel 20 is provided at a lower position of the duct panel 10, the upper side edge of the duct panel 10 is connected to the duct panel 10, and the lower side edge is connected to the vehicle inner side wall 90, so that a structural cavity 40 is formed below the duct panel 10 for accommodating the arrangement line. The technical scheme of this application divides into a main wind chamber 30 and a structural cavity 40 with the inside of current wind channel, sets up a structural cavity 40 alone in the below of whole wind channel structure. So set up, the main wind chamber 30 for carrying air, its cross-sectional area reduces greatly, is favorable to reinforcing the atmospheric pressure in the transfer passage, is convenient for evenly carrying the air outlet of each position in the car with the changes in temperature air. In addition, the structural cavity 40 for accommodating the arrangement pipeline and the main air cavity 30 for conveying air are separated and independently arranged, so that resistance to air conveying caused by the arrangement pipeline in the main air cavity 30 can be avoided, the inside of the main air cavity 30 is more regular, and the air resistance is smaller. In addition, during maintenance, only the maintenance hanging plate 20 is required to be opened to open the structural cavity 40, and the air duct plate 10 is not required to be opened, so that air leakage is not easy to form at the installation position of the air duct plate 10. In addition, at the door position, the structure for opening and closing the door only encroaches on the structural cavity 40 below the main air chamber 30, and has no influence on the main air chamber 30 and no influence on the air transportation. In addition, the pipeline in the structural cavity is not influenced by the air conveyed in the main air cavity, and the service life of the equipment is longer.

Referring to fig. 1, the upper side of the access panel 20 is hinged at a first connection position b, and the lower side installation position is a second connection position a. When the structure is opened, the connection relation of the second connection position a is disassembled, and then the corresponding maintenance hanging plate 20 is operated to rotate around the first connection position b to be opened, so that the structural cavity 40 is opened to maintain the pipeline inside. The second connection location a of the exemplary pair may employ a snap-lock connection. The detachable connection of the second connection location a is not limited herein, and various connection methods in the prior art may be employed.

Further, the duct board 10 has a first type of air outlet 50 disposed thereon. The first type of air outlet 50 is disposed adjacent to the roof inner wall 80 and on a side remote from the access panel 20.

Here, the first type air outlet 50 and the second type air outlet 60 can respectively convey air in the main air chamber 30 to the upper side and the lower side.

Specifically, the first type of air outlet 50 is disposed at a position near the roof inner wall 80 and away from the side of the access panel 20 for delivering air in the main air chamber 30 to a roof position in the vehicle. The second type of air outlet 60 is provided near the underside of the service panel 20 for delivering air downwardly from the main air chamber 30. In this way, the first type air outlet 50 and the second type air outlet 60 can respectively convey the air in the main air chamber 30 to the upper side and the lower side, and the discharged air can cover the space in the vehicle more uniformly, so that good experience can be obtained for passengers under or standing.

In an embodiment of the present application, the air guiding duct 41 is connected between the main air chamber 30 and the second type air outlet 60 for delivering the air in the main air chamber 30 to the second type air outlet 60. Here, the arrangement of the air outlet at the lower side of the service panel 20 is achieved by arranging an air duct 41 in the structural cavity 40.
