DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below. Figures 1 to 6 The embodiment of the utility model provides an air conditioning air intake pipeline interface on a supercharging interface, comprising an air distribution pipe 100, a first connecting member 200, a second connecting member 300 and a side sealing member 400. Figure 4 The side of the air distribution pipe 100 is provided with a side seam 110 along the length direction, and the side seal 400 is connected to the inner side of the air distribution pipe 100 and seals the side seam 110. Figure 3 The air distribution pipe 100 can extend into the interior of the fuselage and be connected to the air conditioning pipeline 500. The first connecting member 200 and the second connecting member 300 are respectively connected to the two ends of the air distribution pipe 100, and the second connecting member 300 is inclined relative to the air distribution pipe 100. The first connecting member 200 is used to connect to the air intake pipeline 600 outside the fuselage, and the second connecting member 300 is used to connect to the fuselage skin 700.

[0025] like Figure 3As shown, the pipeline interface is used to connect the pressurization equipment with the air-conditioning pipeline 500 in the fuselage cabin. The second connecting piece 300 is tilted relative to the air distribution pipe 100, so that the pipeline interface can be better connected to the fuselage skin 700 through the second connecting piece 300, and connected to the air intake pipeline 600 through the first connecting piece 200, and the air intake pipeline 600 is connected with the air-conditioning pipeline 500 inside the fuselage through the air distribution pipe 100, so that the air intake demand at different positions of the fuselage can be met by designing a combined structure on the fuselage skin 700, which has good flexibility. The side of the air distribution pipe 100 is provided with a side seam 110, which can flexibly adjust the size of the air distribution pipe 100, so that the air distribution pipe 100 fits more tightly with the first connector 200 and the second connector 300, thereby achieving assembly convenience and better connection between the air intake pipe 600 and the air conditioning pipe 500 with the first connector 200 and the second connector 300; and the side seal 400 is used to achieve sealing at the side seam 110 to prevent gas from leaking from the side of the air distribution pipe 100. In addition, since the pipeline openings at some fuselage positions cannot be too large, otherwise the integrity of the fuselage structure will be destroyed, and the pipeline interface can achieve the connection between the external air intake pipe 600 and the internal air conditioning pipe 500 through the air distribution pipe 100, the external air intake pipe 600 does not need to extend into the fuselage, so the fuselage position does not need to open an overly large pipeline opening to match the air intake pipe 600, thereby ensuring the integrity of the fuselage structure.

[0026] Furthermore, the width of the side seam 110 can be set to about 2 mm, and the side seam 110 can be filled with sealant, so that the air distribution pipe 100 can better fit the first connector 200 and the second connector 300 while ensuring sufficient side sealing performance. Figure 1 and Figure 2 The cross section of the air distribution pipe 100 is a racetrack shape, a circle or an ellipse, and can be selected by comprehensively considering the size of the wall panel long stringer, the skin 700 in the area between the second connecting member 300 and the size of the pipe opening. Figure 3 and Figure 5 The first connecting member 200 is a flange with an L-shaped longitudinal section. The flange is sleeved on the upper end of the distribution pipe 100, and the end face of the flange is flush with the upper end face of the distribution pipe 100, so as to realize the connection between the pipeline interface and the external air intake pipeline 600. Figure 5 As shown, a plurality of oblique ribs 210 are disposed on the outer periphery of the first connecting member 200 , and the plurality of oblique ribs 210 are distributed along the circumference of the first connecting member 200 to increase the structural strength of the first connecting member 200 .

[0027] Further, refer to Figure 4 and Figure 6The second connecting member 300 includes a mouth frame 310 and a reinforcing plate 320. The mouth frame 310 and the reinforcing plate 320 are sleeved on the outer periphery of the air distribution pipe 100. The mouth frame 310 and / or the reinforcing plate 320 are connected to the fuselage skin 700 through fasteners. The length and width of the reinforcing plate 320 are respectively greater than the length and width of the mouth frame 310. When the mouth frame 310 and / or the reinforcing plate 320 are connected to the fuselage skin 700, it is beneficial to gradually diffuse the load and improve the uniformity of the nail load in the connection area. Preferably, the length of the reinforcing plate 320 is at least 8d greater than the length of the mouth frame 310, and the width of the reinforcing plate 320 is at least 8d greater than the width of the mouth frame 310, where d is the diameter of the fastener, and the fastener can be a rivet or a bolt. Furthermore, the mouth frame 310 includes a sleeve portion 311 and a flange 312, the sleeve portion 311 and the flange 312 are integrally formed, the sleeve portion 311 is sleeved on the air distribution pipe 100, the flange 312 is connected to the reinforcement plate 320 and / or the fuselage skin 700, and the flange 312 is set at an angle with the sleeve portion 311, and then, as shown in FIG. Figure 3 As shown, the flange 312 is set at an angle with the length direction of the air distribution pipe 100 to achieve a relative tilt setting between the second connecting piece 300 and the air distribution pipe 100. The size of this angle is related to the position of the fuselage opening and the connection end face requirements of the air intake pipe 600, and can be adjusted according to actual conditions to ensure the flexibility of the installation position.
