[0022] The present application will be further described below with reference to the accompanying drawings and examples.

[0023] The present application discloses a sealing structure of a wing slide enclosure housing, such as Figure 1 and Figure 2As shown, it includes a package shell 2 and a package cover 1, the package shell 2 is used to accommodate the slide bag, and the package cover 1 is used to seal the opening of the package shell 2. The shape of the package cover 1 matches the opening of the package shell 2, and a protruding step a is provided on the front side A of the opening of the package shell 2. A rectangular slot is provided on the front side A of the opening of the package shell 2. A positive pressure sealing strip 4 is continuously fixed on the front side A of the opening of the package shell 2, and side pressure sealing strips 3 are continuously fixed on the other side surfaces (B, C, D). The positive pressure sealing strip 4 is located below the slot, and the side pressure sealing strip 3 is also extended to the transition corners at both ends of the front side A. The front edge of the package cover 1 is limited by being inserted into the rectangular slot through the protruding step. The bottom surface of the front edge of the package cover 1 is squeezed on the top surface of the positive pressure sealing strip 4, and the other sides are squeezed laterally on the side surfaces of the side pressure sealing strip 3. The package cover plate 1 cooperates with the positive pressure sealing strip 4 and the side pressure sealing strip 3 to seal all edges of the opening of the package shell 2 to form a closed cavity, preventing water from entering the cavity and avoiding the hidden danger of causing the slide bag to fail.

[0024] like Figure 2 As shown, in this embodiment, a pad 5 is fixed inside the package shell 2. The pad 5 is located at the transition corners at both ends of the front side of the opening of the package shell 2. Part of the pad 5 supports the transition corner, and the other part supports and fixes the side pressure sealing strip 3. The side pressure sealing strip 3 is in a tortuous state at the transition corner. If there is no support, it cannot form an effective seal. The use of the pad 5 to support the side pressure sealing strip 3 can ensure the formation of an effective seal, and can also support the transition corner itself, thereby improving the structural strength. Figure 2 and Figure 5 As shown, in this embodiment, the pad 5 at the transition corner far from the fuselage adopts a stepped structure, the top surface of which supports the transition corner, and the stepped surface supports and fixes the side pressure sealing strip 3, as shown in FIG. Figure 2 and Figure 6 As shown, in this embodiment, the spacer 5 at the transition corner near the fuselage adopts a rectangular block structure. Its top surface supports both the transition corner and the side pressure sealing strip 3. The plate at the transition corner far from the fuselage is thinner, and the side pressure sealing strip 3 is thicker than the plate, resulting in a dimensional difference. The stepped structure can compensate for this dimensional difference. In this embodiment, the spacer 5 is fixed to the enclosure shell 2 by bolts.

[0025] like Figure 3 As shown, in this embodiment, the cross section of the side pressure sealing strip 3 is a right-angled trapezoid with a small top and a large bottom. The right-angled side is fixed to the opening of the package shell 2, and the inclined side is matched with the package cover plate 1. Figure 4 As shown, in this embodiment, the cross-section of the positive pressure sealing strip 4 is rectangular, and the shape design of the side pressure sealing strip 3 and the positive pressure sealing strip 4 allows for better contact and extrusion effect with the package cover plate 1. In this embodiment, the side pressure sealing strip 3 and the positive pressure sealing strip 4 are fixed to the opening of the package shell 2 by adhesive bonding using a sealant.

[0026] In this embodiment, the front surface of the package cover plate 1 forms the outer surface of the aircraft skin, and the package cover plate 1 and the package shell 2 are made of carbon fiber composite materials.

[0027] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
