For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides an airbag structure for an air-cushioned boat, comprising an airbag body 1 and a partition 2. The partition 2 is sealed to the inner wall of the airbag body 1 to form a gas chamber 10 within the airbag body 1, and the partition 2 protrudes along the axial direction of the airbag body 1.

[0030] The partition 2 includes at least two partition pieces 20, each partition piece 20 having an inner edge 21 and an outer edge 22. The at least two partition pieces 20 are spliced ​​together along the inner edge 21, and an adhesive strip 23 is connected between the inner edges 21 of two adjacent partition pieces 20. The outer edge 22 is bonded and fixed to the inner wall of the airbag body 1. The protruding end of the partition 2 is also provided with a reinforcing piece 24, which is bonded and fixed to the at least two partition pieces 20 and the adhesive strip 23 respectively.

[0031] The skirt air bag structure of the air cushion vehicle adopts the design form of air bag body 1 and partition piece 2, the partition piece 2 is sealingly connected to the inner wall of the air bag body 1, and the air bag body 1 is partitioned into gas cavities 10 by the partition piece 2. The gas cavities 10 constitute independent spaces, and even if the air bag body 1 is partially damaged, the sealing of the remaining gas cavities 10 can still be ensured.

[0032] Furthermore, the partition piece 2 is protrudingly arranged along the axial direction of the air bag body 1, and the partition piece 2 can adaptively deform with the pressure change of the gas cavities 10 on both sides. For example, under normal circumstances, the partition piece 2 protrudes towards the gas cavity 10 on one side. If the gas cavity 10 on the other side leaks, the pressure of the gas cavity 10 on the other side decreases, which in turn drives the partition piece 2 to protrude and deform towards the other side, thereby expanding the volume of the gas cavity 10 and ensuring the stability of the air cushion support.

[0033] Among them, at least two partition pieces 20 are spliced and combined along the inner side edge 21, and an adhesive tape 23 is connected between the inner side edges 21 of the adjacent two partition pieces 20. The outer side edge 22 is adhesively fixed to the inner wall of the air bag body 1. The adjacent two partition pieces 20 are adhesively connected along the inner side edge 21 by the adhesive tape 23 to form a whole. The outer side edge 22 is adhesively connected to the inner wall of the air bag body 1, and the partition piece 2 forms a reliable sealing connection effect in the air bag body 1. In addition, the protruding end of the partition piece 2 is also provided with a reinforcing piece 24, which strengthens the connection of the spliced weak part of the at least two partition pieces 20, improves the structural strength of the whole partition piece 2, and prevents the air leakage problem caused by the weak adhesion of the diaphragm piece to the air bag inner wall.

[0034] In the embodiment, the outer contour of the partition piece 2 is hemispherical, and the hemispherical partition piece 2 has the characteristics of smooth surface, easy adhesion and reliable adhesion, and the concave-convex deformation of the partition piece 2 is more smooth. In order to meet different use requirements, in other embodiments, the outer contour of the partition piece can be designed as any one of hemi-ellipsoidal, conical and pyramidal, which can also adaptively deform with the pressure change of the gas cavities on both sides.

[0035] As a further preferred scheme, the air bag body 1 is a cylindrical air bag, and the at least two partition pieces 20 are spliced and connected in sequence around the inner wall of the air bag body 1. As shown in Figure 4 The outer side edge 22 of the partition piece 20 is a circular arc edge, which is matched with the inner wall of the air bag body 1 to ensure that the partition piece 20 and the air bag body 1 form a sufficient adhesion effect.

[0036] And, the adhesive tape 23 is arranged along the inner surface of the partition member 2 and between the outer side edge 22 and the protruding end. In other embodiments, in order to meet different use requirements, the adhesive tape can be arranged along the outer surface of the partition member and between the outer side edge and the protruding end; or, the adhesive tape is arranged along the inner surface and the outer surface of the partition member and between the outer side edge and the protruding end.

[0037] Correspondingly, the reinforcing sheet 24 is provided with two, one reinforcing sheet 24 is attached to the outer surface of the protruding end of the partition member 2, and the other reinforcing sheet 24 is attached to the inner surface of the protruding end of the partition member 2. The reinforcing sheet 24 is attached to the inner surface and the outer surface of the protruding end of the partition member 2, thereby effectively strengthening the connection of the weak part where the plurality of reinforcing sheets 24 are spliced.

[0038] In addition, the partition member 2 is arranged at least two in the middle of the air bag body 1, and the at least two partition members 2 are arranged protruding to the same side along the axis direction of the air bag body 1. It should be noted that the partition sheet 20 is an elastic rubber sheet, the material of the partition sheet 20 is the same as the material of the air bag body 1, and the adhesive effect of the same material is better. The adhesive tape 23 is a flexible adhesive tape, and the reinforcing sheet 24 is a flexible reinforcing sheet. The adhesive tape 23 and the reinforcing sheet 24 are flexible components, which avoids adding a hard support on the partition member 2, and ensures that the partition member 2 can smoothly adapt to deformation when the pressure of the two side cavities changes, so as to effectively expand the volume of the gas cavity 10.

[0039] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
