The mounting holes 101 are fixedly mounted to the bottom of the amphibious vehicle by bolts. A motor compartment 103 is arranged on the lower side of the shell 1. A propulsion structure is arranged in the motor compartment 103. A sliding box cover 2 is arranged on the opening surface of the motor compartment 103. The box cover 2 slides so as to cover the motor compartment 103. A waterproof motor 5 is arranged on the side of the motor compartment 103. A guide rail is arranged on the side of the waterproof motor 5. A screw rod 6 is arranged on the waterproof motor 5. The screw rod 6 is connected to the waterproof motor 5. The screw rod 6 is controlled by the waterproof motor 5. The waterproof motor 5 drives the screw rod 6 to rotate. A slider 7 is arranged on the guide rail on the side of the waterproof motor 5. The screw rod 6 is connected to the waterproof motor 5. The screw rod 6 is controlled by the waterproof motor 5. The waterproof motor 5 drives the screw rod 6 to rotate. 6 passes through the slider 7. When the screw rod 6 rotates, it will drive the slider 7 to move, so that the slider 7 can move on the guide rail. The slider 7 is connected and fixed to the box cover 2, so that the box cover 2 can move when the slider 7 slides. A guide rod 8 is arranged on the other side of the motor compartment 103. The guide rod 8 is fixed on the shell 1. A sliding plate 9 is arranged on the guide rod 8. The sliding plate 9 has a circular hole in the middle. The sliding plate 9 is sleeved on the guide rod 8. The bottom of the sliding plate 9 is connected and fixed to the box cover 2. When the box cover 2 moves due to the movement of the slider 7, the sliding plate 9 will also move accordingly on the guide rod 8.
[0033] A propulsion structure is arranged in the motor compartment 103, and the propulsion structure includes a propulsion motor 4, which is arranged on a steering servo 403. Rotating servos 402 are arranged on both sides of the steering servo 403, and the rotating servos 402 are fixedly arranged inside the motor compartment 103; the propulsion motor 4 is a rim motor, and a plurality of blades 401 are arranged on the rotating surface of the propulsion motor 4, and the number of the blades 401 is 3-9 pages; after the propulsion motor 4 is energized, the rotating surface rotates, driving the blades 401 on the rotating surface to rotate to realize the flow of water.
[0034] The control box 3 in the housing 1 control compartment 102 controls the opening and closing of the box cover 2, and also controls the expansion and contraction of the propulsion motor 4.

The amphibious vehicle can float smoothly on the water surface when entering the water without bumps or tilts. At this time, the personnel in the vehicle start the underwater propulsion device, and the control compartment 102 is commanded to control the waterproof motor 5 to start. The waterproof motor 5 starts to drive the screw rod 6 to rotate, and the rotation of the screw rod 6 drives the sliding of the slider 7. The slider 7 moves to drive the movement of the box cover 2 to open the box cover 2. At the same time, the control panel in the control box 3 controls the rotating steering gear 402 to realize the rotation of the steering steering gear 403.
