[0032] The car body air duct assembly provided by the embodiments of the present application is assembled in the car body of a passenger car for delivering cold or warm air to various positions in the car body. The car body air duct assembly comprises an air duct body and a door plate. The air duct body comprises a foamed material and a profile, the length direction of the profile is consistent with the extension direction of the air duct body, and the foamed material and the profile are combined to form an integrated structure. The air duct body is provided with an inspection opening along the extension direction thereof. The door plate comprises a foamed material and a profile, the length direction of the profile is consistent with the extension direction of the air duct body, and the foamed material and the profile are combined to form an integrated structure. The door plate is installed on the air duct body and used to cover the inspection opening. The door plate can be adjusted to an open state to open the inspection opening or adjusted to a closed state to close the inspection opening. The profile is an object with a certain geometric shape made of iron or steel and a material with certain strength and toughness through rolling, extrusion, casting or other processes. Specifically, the profile can be an aluminum profile.

[0033] The air duct body is combined by the foamed material and the profile. During production, the profile is placed at a predetermined position in a foaming mold. During the foaming process, the foamed material fills the internal space of the foaming mold and is combined with the profile in the foaming mold, thereby manufacturing a foamed piece containing the profile. Therefore, the air duct body is a one-piece foamed piece and can be installed as a whole on the frame in the car body. In addition, the air duct body is a foamed piece, which is light in weight, not easy to rust, good in heat insulation, good in integrity, not easy to produce loose noise, air leakage, condensate water and other phenomena.

[0034] The door plate is combined by the foamed material and the profile. During production, the profile is placed at a predetermined position in a foaming mold. During the foaming process, the foamed material fills the internal space of the foaming mold and is combined with the profile in the foaming mold, thereby manufacturing a foamed piece containing the profile. Therefore, the door plate is a one-piece foamed piece and can be installed as a whole on the air duct body. In addition, the door plate is a foamed piece, which is light in weight, not easy to rust, good in heat insulation, good in integrity, not easy to produce loose noise, air leakage, condensate water and other phenomena.

[0035] The air duct body and the door plate are both foamed parts, various structural features of which can be directly formed through a foaming process, thereby omitting a large amount of machining process. The main structure of the vehicle cabin air duct assembly is formed by the air duct body and the door plate, and the air duct body and the door plate are both formed into an integrated structure by combining foamed material and profiled material. When assembled, the door plate can be pre-assembled on the air duct body to form a complete air duct structure, and then the air duct structure is assembled into the vehicle cabin as a whole, thereby achieving high assembly efficiency and better assembly quality control.

[0036] Referring to Figure 1 and Figure 2 , the vehicle cabin air duct assembly includes an air duct body 10 and a door plate 20. The air duct body 10 includes foamed material and profiled material, the length direction of the profiled material is consistent with the extension direction of the air duct body 10, and the foamed material and the profiled material are combined to form an integrated structure.

[0037] The vehicle cabin air duct assembly is in a long strip structure and can be arranged on both sides of the top of the vehicle cabin. The door plate 20 is assembled on the air duct body 10, and the door plate 20 can be adjusted to an open state to open the inspection opening 15 or adjusted to a closed state to close the inspection opening 15. In Figure 1 , the door plate 20 is in a closed state and completely covers the inspection opening 15. In Figure 2 , the door plate 20 is in an open state and exposes the inspection opening 15, and a maintenance personnel can perform maintenance through the inspection opening 15.

[0038] The air duct body 10 and the door plate 20 extend in the same direction and are assembled together to form a long strip vehicle cabin air duct assembly. Referring to Figure 1 and Figure 2 , a plurality of door plates 20 are arranged along the extension direction of the air duct body 10, and each door plate 20 is independently assembled on the air duct body 10. Therefore, each door plate 20 can be opened individually, and a maintenance personnel can open a door plate 20 at a specific position as needed to perform maintenance.

[0039] Referring to Figures 3-5The air duct body 10 comprises a first profile 11 and a second profile 12, and the inspection opening is arranged between the first profile 11 and the second profile 12. The two side edges of the door plate 20 are respectively provided with a fifth profile and a sixth profile 22. The fifth profile 21 is rotatably combined with the first profile 11 to form a first connection relationship. Based on the first connection relationship, the door plate 20 can be rotated to an open state or a closed state relative to the air duct body 10. When the door plate 20 is rotated to the closed state, the sixth profile 22 is close to the second profile 12. When the door plate 20 is rotated to the open state, the sixth profile 22 is away from the second profile 12. A second connection relationship is arranged between the door plate 20 and the air duct body 10, which can apply a limit to the door plate 20 when the door plate 20 is in the closed state to limit the door plate 20 in the closed state, and can remove the limit to allow the door plate 20 to rotate.

[0040] In an embodiment, the first profile 11, the second profile 12, the third profile 13, and the fourth profile 14 are sequentially arranged on the air duct body 10.

The length direction of the first profile 11, the second profile 12, the third profile 13, and the fourth profile 14 is consistent with the extension direction of the air duct body 10.

[0041] In an embodiment, the two side edges of the door plate 20 are respectively provided with a fifth profile 21 and a sixth profile 22. The fifth profile 21 and the sixth profile 22 are combined on the foamed material B 24 to form an integrated structure. The length direction of the fifth profile 21 and the sixth profile 22 is consistent with the extension direction of the air duct body 10.

[0042] The fifth profile 21 on the door plate 20 and the first profile 11 on the air duct body 10 form a first connection relationship, which is a rotating connection relationship, allowing the door plate 20 to rotate relative to the air duct body 10. The sixth profile 22 on the door plate 20 corresponds to the second profile 12 on the air duct body 10. When the door plate 20 is rotated to the closed state, the sixth profile 22 is close to the second profile 12. When the door plate 20 is rotated to the open state, the sixth profile 22 is away from the second profile 12. In an embodiment of the present application, the fifth profile 21 is provided with a recessed groove 211, and the recessed groove 211 is provided with a reel sleeve 212. The reel sleeve 212 is a hollow structure and has a lateral opening. The first profile 11 is provided with an embedded part 111, which can be inserted into the reel sleeve 212 from the lateral opening to form a first connection relationship that can rotate relative to the fifth profile 21.

[0043] The second connection relationship is an adjustable locking connection relationship, and is used to apply a limit to the door plate 20 to limit the door plate 20 in the closed state when the door plate 20 is in the closed state. When the door plate 20 needs to be opened, the second connection relationship is cancelled to remove the limit to allow the door plate 20 to rotate. In an embodiment of the present application, a lock 30 is mounted on the air duct body 10, which can apply a limit to the sixth profile 22 to limit the door plate 20 in the closed state when the door plate 20 is in the closed state, and can remove the limit to allow the door plate 20 to rotate, thereby forming the second connection relationship.

[0044] In the embodiment of the present application, a plurality of door plates 20 are arranged along the extension direction of the air duct body 10, and each door plate 20 is independently assembled on the air duct body 10. It should be understood that all the door plates 20 are installed with the first profile 11 and the second profile 12 on the air duct body 10 as a reference, with high assembly accuracy, so that all the door plates 20 can be strictly aligned, thereby forming a flat and continuous interior surface of the vehicle compartment along the extension direction of the air duct body 10.

[0045] Reference Figure 3 In an embodiment of the present application, the second profile 12 is arranged with a sealing strip 121 along the length direction thereof; the sealing strip 121 corresponds in position to the sixth profile 22, so that when the door plate 20 is rotated to the closed state, the sixth profile 22 can contact and extrude the sealing strip 121. The sealing strip 121 can make the second profile 12 and the sixth profile 22 more closely combined, increase the sealing property, and avoid loose and abnormal sound.
