The utility model relates to a sealing structure of a thin-wall armored vehicle door. The problem that an existing thin-wall armored vehicle door is poor in sealing property is solved. The sealing structure of the thin-wall armored vehicle door comprises a door frame, a door cover and a U-shaped hollow sealing strip, wherein a rubber sealing strip is arranged around the door cover, and the compression amount of the U-shaped hollow sealing strip is variable. The door frame is fixedly connected with a vehicle body, the U-shaped hollow sealing strip with the variable compression amount is bonded on a door frame pressing strip, and a hollow rubber gasket is arranged at the top end of the U-shaped hollow sealing strip. The gap between the U-shaped hollow sealing strip and the door frame pressing strip is filled with silicone sealant, the rubber sealing strip arranged around the door cover is a foaming EPDM sealing rubber mat, and adhesives are used for fixing. By the adoption of the sealing strip structure, the problem that the existing thin-wall armored vehicle door is poor in sealing property is solved fundamentally, it is guaranteed that leakage of a vehicle is avoided in the floating-crossing process on the water, and the sealing property cannot be affected by vehicle body deformation after the vehicle travels on the complex road condition.
