Technical Field
[0001] The utility model relates to the installation of a floating airbag, in particular to a flexible skin packaging structure. Background Art
[0002] The floating airbags equipped with aerospace flight equipment such as drones and spacecraft are in a sealed state when not in operation. In the event of an emergency landing, the airbags are inflated and deployed, and the constraints of the seal are simultaneously released to help the flight equipment complete the forced landing on water and float stably.
[0003] At present, the hard skin commonly used as the packaging structure of floating airbags is not only expensive and has a complex molding process, but also, during use, after the floating airbag is inflated and deployed, the released hard skin may collide with the flight equipment or the hard skin may be damaged and scratch the floating airbag, affecting flight safety and forced landing performance.

[0006] A flexible skin packaging structure includes a mounting frame, an upper packaging cloth, a lower packaging cloth and an adjustable overlapping cloth. The bottom surface of the mounting frame is used to install a floating airbag. The upper ends of the upper packaging cloth and the lower packaging cloth are respectively connected to the two side surfaces of the mounting frame, and the lower ends are used to enclose and package the floating airbag. The lower ends of the upper packaging cloth and the lower packaging cloth are respectively provided with an upper packaging adhesive strip and a lower packaging adhesive strip. The adjustable overlapping cloth includes an upper tightening strip, a lower tightening strip and a tightening rope. One side of the upper tightening strip is connected to the inner side of the lower part of the upper packaging cloth, and the other side is provided with an eyelet. One side of the lower tightening strip is provided with a overlapping adhesive strip, and the other side is connected to the tightening rope. The tightening rope passes through the corresponding eyelet.
[0007] Preferably, the mounting frame is a U-shaped frame with an opening facing upward.
[0008] Preferably, the upper ends of the upper wrapping cloth and the lower wrapping cloth are both pressed and connected to the side of the mounting frame through a groove-shaped pressing plate.
[0009] Preferably, the floating airbag is adhesively fixed to the bottom surface of the mounting frame.
[0010] Preferably, the upper tightening strip is sewn and connected to the inner side of the lower portion of the upper wrapping cloth.
[0011] Preferably, the upper and lower packing cloths, the upper and lower tightening strip cloths and the tightening rope are all made of fireproof woven fabric.
[0012] The utility model has the advantages of:
[0013] The structure uses a flexible skin to replace a hard skin, so as not to collide with flight equipment and scratch the floating air bag. After unsealing, the upper and lower packing cloths and the adjustable lap cloth are still connected to the mounting frame, so as not to pose a safety threat, thus not affecting flight safety and forced landing water landing performance.

DETAILED DESCRIPTION
[0019] The application will be further described below in combination with the drawings and examples.
[0020] The application discloses a flexible skin packing structure, as shown in the figure: Figures 1 to 4 including a mounting frame 1, an upper packing cloth 4, a lower packing cloth 5 and an adjustable lap cloth 6. The bottom surface of the mounting frame 1 is used for mounting a floating air bag 3. The upper ends of the upper packing cloth 4 and the lower packing cloth 5 are connected to the two side surfaces of the mounting frame 1 respectively, and the lower ends are used for enclosing and packing the floating air bag 3. The lower ends of the upper packing cloth 4 and the lower packing cloth 5 are respectively provided with an upper packing adhesive strip 7 and a lower packing adhesive strip 8. The adjustable lap cloth 6 comprises an upper tightening strip cloth 11, a lower tightening strip cloth 10 and a tightening rope 13. One side of the upper tightening strip cloth 11 is connected to the lower inner side of the upper packing cloth 4, and the other side is provided with an eyelet 12 along a line. One side of the lower tightening strip cloth 10 is provided with a lap adhesive strip 9, and the other side is connected to the tightening rope 13 along a line. The tightening rope 13 passes through the corresponding eyelet 12.
[0021] The structure can realize packing and does not affect inflation and unfolding. When the floating air bag 3 is packed, the floating air bag 3 is first folded into a smaller volume, as shown in Figure 2 As shown, the overlapping adhesive strip 9 is firmly bonded to the lower sealing adhesive strip 8 to achieve preliminary sealing. At this time, since the adjustable overlapping cloth 6 is longer, the sealing is not compact enough and is relatively loose. Figure 3 As shown, it is necessary to tighten the tightening rope 13 again to drive the upper wrapping cloth 4 to move downward, as shown in FIG. Figure 4 As shown, until the upper package adhesive strip 7 can be bonded with the lower package adhesive strip 8, the package is fixed, and the package is cylindrical as a whole after completion. When the floating airbag 3 is inflated and deployed, the floating airbag 3 is rapidly inflated and expanded, overcoming the adhesive force and the friction force of the tightening rope 13 to complete the inflation and forming.
[0022] like Figures 1 to 4 As shown, in this embodiment, the mounting frame 1 is a U-shaped frame with an opening facing upward.
[0023] like Figures 1 to 4 As shown, in this embodiment, the upper ends of the upper wrapping cloth 4 and the lower wrapping cloth 5 are both pressed and connected to the side of the mounting frame 1 through the groove-shaped pressing plate 2.
[0024] In this embodiment, the floating airbag 3 is bonded and fixed to the bottom surface of the mounting frame 1 .
[0025] In this embodiment, the upper tightening strip 11 is sewn and connected to the inner side of the lower portion of the upper wrapping cloth 4 .
[0026] In this embodiment, the upper wrapping cloth 4, the lower wrapping cloth 5, the upper tightening cloth 11, the lower tightening cloth 10 and the tightening rope 13 are all made of fireproof braided fabric.
[0027] The upper and lower wrapping fabrics 4, 5, and adjustable overlap fabrics 6 in this structure are simple to manufacture and install. Compared to a rigid cover, they are not only cost-effective but also flexible and adjustable to the size of the flotation airbag 3, making them highly adaptable. This structure uses a flexible cover instead of a rigid cover, preventing collisions with flight equipment or scratches on the flotation airbag 3. Even after unsealing, the upper and lower wrapping fabrics 4, 5, and adjustable overlap fabrics 6 remain attached to the mounting frame 1, posing no safety threat and, therefore, not affecting flight safety or water landing performance.
[0028] 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.
