Preferably, the first seam allowance of the passenger compartment and the second seam allowance of the transmission cover are close to being perpendicular to each other in space.
Further preferably, the second weather strip has a jacket portion and an elastic sealing portion; at the first seam allowance, the clamping sleeve part of the second sealing strip is clamped and sleeved on the first seam allowance, and the elastic sealing part is embedded into a U-shaped space surrounded by the first seam allowance, the mounting surface of the passenger compartment and the inner wall of the transmission cover for sealing; and at the second seam allowance, the clamping sleeve part of the second sealing strip is clamped and sleeved on the second seam allowance, and the elastic sealing part is embedded into a space surrounded by the second seam allowance, the inner wall of the transmission cover and the first seam allowance for sealing.
According to the structural description, the whole set of composite sealing structure adopts three layers of sealing, namely the second stop, the first stop and the mounting joint surface of the passenger cabin and the transmission, has compact structure, simple and convenient mounting, safety and reliability, is particularly suitable for sealing when an armored vehicle wades, and meets the use requirement of the whole vehicle.
