There is also a support bearing 14 between the vehicle frame 7 and the transmission frame 9, which is used to support the transmission frame 9, so that the distance between the vehicle frame 7 and the transmission frame 9 remains constant, ensuring the stability of the transmission frame 9 during rotation. The central gear 6 is arranged horizontally, and is fixed on the upper part of the vehicle frame 7 between the vehicle seat body 8 and the vehicle frame 7 . There is a bearing connecting the transmission frame 9 and the vehicle frame 7 , so that the transmission frame 9 can rotate relative to the vehicle frame 7 , and the vehicle seat body 8 can rotate synchronously with the transmission frame 9 . The steering member 4 is rotatably fixed on the vehicle seat body 8 through a bearing, and its lower end has a planetary gear 5 fixedly connected thereto. The planetary gear 5 is meshed with the sun gear 6 and can rotate along the circumferential direction of the sun gear 6 . Under the rotation of the steering member 4, the planetary gear 5 can drive the seat body 8 to rotate 360 degrees relative to the vehicle frame 7, so that the driver can observe the scene around the amphibious vehicle in all directions. The ring gear 3 is horizontally fixed on the transmission frame 9 , is in line with the center of the central gear 6 , and can rotate synchronously with the transmission frame 9 . Both the connecting gear 2 and the driven gear 1 are rotatably fixed on the vehicle frame 7 , the connecting gear 2 is meshed with the ring gear 3 , and the driven gear 1 is meshed with the connecting gear 2 . Under the connecting action of the connecting gear 2, the driven gear 1 can rotate in the same direction as the ring gear 3. The outer retaining ring 17 includes an inner ring gear and a track, is meshed with the connecting gear 2 , and is rotatably connected with the vehicle frame 7 .

As shown in FIG. 3 and referring to FIG. 2 , an amphibious vehicle includes the above-mentioned rotating structure of the amphibious vehicle, a floating body 15 , a cover body 16 , a driving wheel 12 , and a driven wheel 13 . An amphibious vehicle includes not less than three driven wheels 13 and one driving wheel 12 . Driven wheel 13 is fixedly connected with driven gear 1 by driven connection shaft 10, can carry out synchronous deflection under the drive of driven gear 1, driven wheel 13 does not have driving and brake function, has balance vehicle body and prevents vehicle frame 7 from rotating effect. The driving wheel 12 is fixedly connected with the seat body 8 through the drive connection shaft 11 , and can rotate synchronously with the seat body 8 . The driving wheel 12 and the driven wheel 13 are arranged in the same direction. The driving wheel 12 is arranged in the geometry formed by the line connecting the driven wheels 13, so that the driven wheels 13 can support the amphibious vehicle. Preferably, a rotating structure of an amphibious vehicle includes four driven wheels 13, the driven wheels 13 form a parallelogram structure, and the driving wheel 12 is located at the geometric center of the parallelogram to ensure sufficient driving stability of the amphibious vehicle. The floating body 15 is fixed on the lower part of the side of the vehicle frame 7, and is located between two adjacent driven wheels 13, so that the positions of the floating body 15 and the driven wheels 13 do not conflict, and the rotation of the driven wheels 13 will not be hindered.
