[0002] A rubber lifeboat is a lifeboat made of natural or synthetic rubber material. It is widely used in emergency rescue and water activities because of its waterproof, wave-proof, drop-resistant and wear-resistant properties, and is easy to carry. Rubber lifeboats are usually designed as inflatable structures, which are easy to store and transport, and can be quickly deployed in a short time to provide effective lifesaving means for people in distress.

[0003] With the increasing demand for water activities and emergency rescue, higher requirements are placed on the portability, adaptability and economy of rubber lifeboats. The bottom plate of existing rubber lifeboats is usually an integrated structure that can be folded, but it cannot achieve rigid structural strength, resulting in the rubber lifeboat being easily scratched when used in harsh environments (complex river waters such as reefs and tree branches), resulting in risks such as leakage and sinking.
