The inflatable semi-rigid sealed cabin adopting the compressible multilayer sandwich protective layer according to claim 7, wherein: each sleeve barrel wall of each auxiliary unfolding multistage sleeve (4) is made of a metal material, and the thickness range of the sleeve barrel wall of each auxiliary unfolding multistage sleeve (4) is 0.5-10 mm.
9. The inflatable semi-rigid sealed cabin adopting the compressible multilayer sandwich protective layer according to claim 1, wherein: the sealed pressure-bearing inner bag (2) is formed by bonding an inner layer with a gas barrier function and an outer layer with a bearing function.
10. An inflatable semi-rigid sealed cabin with compressible multi-layer sandwich protective layer according to claim 1 or 9, wherein: a compressed gas cylinder (8) is placed in the sealed pressure-bearing inner bag (2), and gas is filled into the auxiliary expansion multi-stage sleeve (4) through a gas control valve on the compressed gas cylinder (8) or directly filled into the sealed pressure-bearing inner bag (2), so that the inflation expansion of the inflatable cabin is realized.
