[0022] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0023] Reference Figure 1As shown, the apron of a hovercraft is an important component of the hovercraft structure, providing sufficient performance support for its operation. Most existing hovercraft aprons use bolt-plate fixing structures, leading to stress concentration on a rigid connection. This causes cracks at the apron edges, poor sealing performance, and significant air cushion pressure loss, hindering the continuous use of the hovercraft. To address these issues, a flexible apron fixing structure for hovercraft is proposed, including an apron body 1 and fixing straps 2 located on the circumferential edge of the apron body 1. The apron body 1 also has a connecting base 3 for connecting to the hull surface. Furthermore, it includes a modular connecting assembly 4 connecting the fixing straps 2 and the connecting base 3. The connecting assembly 4 includes components opened on the apron body... The skirt body 1 has several slots 41 on its inner side and limiting parts 42 that cooperate with the slots 41. The two are locked together by locking teeth 43 with self-locking function. The connecting base 3 is also provided with an emergency release device 6 for automatic separation when the skirt is subjected to tensile force exceeding a set threshold. The three-layer structure of the skirt body, the fixing strap and the connecting base can form a better sealing interface, so that the air cushion pressure loss is minimized. The slots and teeth in the limiting parts can achieve quick assembly and disassembly. The entire connection structure is relatively flexible, so that the stress distribution of the entire air cushion apron is uniform. The emergency release device makes the disassembly of the entire structure more convenient and avoids the problem of being unable to disassemble in an emergency.

[0024] It should be noted that the fixing strap 2 is composed of a polyester fiber woven layer and a polyurethane wear-resistant coating. The combination of the polyester fiber woven layer and the polyurethane wear-resistant coating can ensure and improve the strength and performance of the fixing strap 2.

[0025] Furthermore, the limiting part 42 and the connecting base 3 are hollowly arranged, and a plurality of connecting rods 421 for fixing the limiting part 42 are provided between them; the setting of the connecting rods 421 can achieve the stability of the limiting part 42 in the connecting base 3, and ensure that the limiting of the tooth 43 and the slot 41 is more stable.

[0026] It should also be noted that the emergency detachment device 6 includes a pressure triggering unit 61 located within the limiting part 42 and a guide groove 62 located within the limiting part 42 for the extension and retraction of the locking teeth 43. One end of the locking teeth 43 extends into the guide groove 62 and its extension and retraction are controlled by the pressure triggering unit 61. The emergency detachment device 6 ensures that when the hovercraft skirt is entangled in water plants during use, the entire hovercraft skirt can be detached by retracting the locking teeth 43, thus preventing the hovercraft from being trapped for a long time.

[0027] Additionally, the locking teeth 43 are arranged symmetrically in an up-down pattern and penetrate the connecting base 3 to engage with the locking slot 41.

[0028] It is worth mentioning that the fixing band 2 is made of silicone rubber foam material.

[0029] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
