The roll mechanism 3 mainly comprises a roll motor 31, a roll speed reducer 32, a roll motor mounting seat 33 and a roll support 34. The roll motor 31 is preferably a servo motor, and can significantly improve the operation accuracy. The roll motor mount 33 and roll mount 34 are mounted and secured to the base 2 in a side-by-side manner. The roll motor mounting seat 33 is a triangular supporting block, and the shell of the roll motor 31 is fixed in the roll motor mounting seat 33 in a clamping manner. The roll support 33 includes two sets of support bodies, which may be triangular support structures, and the two sets of support bodies are fixed on the base 2 in a spaced and parallel manner, and one set of support bodies is close to the roll motor mounting seat 33. The roll speed reducer 32 is arranged between the roll motor mounting seat 33 and the supporting body, and the roll motor 31 is in driving connection with the roll speed reducer 32.

The pitch mechanism 4 mainly includes a pitch motor 41, a pitch speed reducer 42, a pitch motor mount 43, and a pitch output mounting plate 44. The pitching motor 41 is preferably a servo motor, and can effectively improve the accuracy of the motion. The pitch motor mounting seat 43 is rotatably connected between two groups of support bodies of the roll support 34, and a power output shaft of the roll speed reducer 32 is connected with the pitch motor mounting seat 43 to drive the pitch motor mounting seat 43 to perform a roll motion of a predetermined angle. The pitching motor 41 is installed in the pitching motor mounting seat 43 in a sitting manner, and the pitching motor 41 synchronously moves along with the pitching motor mounting seat 43. The pitching motor 41 is in driving connection with the pitching speed reducer 42, the pitching output mounting plate 44 is connected to a power output shaft of the pitching speed reducer 42, and the pitching motor 41 drives the pitching output mounting plate 44 to perform pitching motion through the pitching speed reducer 42. The frame 1 is mounted on a pitch output mounting plate 44. In some embodiments, a table top support 45 and a table top 46 are mounted on the pitch output mounting plate 44, and the table top 46 is connected to the pitch output mounting plate 44 through the table top support 45, and at this time, the frame 1 is fixed to the table top 46, and the stability of the frame 1 is improved by enlarging the contact area with the frame 1.

The working principle of the utility model is as follows: when the ship body tilts left or tilts right under the influence of sea waves, taking the case that the main control module 5 collects that the ship body tilts left by 5 degrees as an example, the main control module 5 transmits instructions to the roll motor 31 to perform corresponding rotation motions, the roll speed reducer 32 drives the pitching mounting seat 43 to roll right by 5 degrees, and the bedstead 1 rolls right by 5 degrees along with the pitching mounting seat 43 synchronously, so that the bedstead 1 is kept in a horizontal state, namely a horizontal state of basically 0 degrees. When the ship body is lifted or lowered under the influence of sea waves, taking the situation that the main control module 5 collects the lifted ship head for 5 degrees as an example, the main control module 5 transmits instructions to the pitching motor 41 to perform corresponding rotation motions, and the pitching output mounting plate 44 is driven by the pitching speed reducer 42 to perform the downward 5 degrees motion opposite to the lifted ship head, so that the bed frame is kept in a horizontal state of basically 0 degrees. When the ship body is subjected to wave influence and has roll and pitch, the main control module 5 is used for collecting that the ship body is inclined rightly for 5 degrees and overlapping the bow to dip for 5 degrees, the main control module 5 simultaneously transmits instructions to the roll motor 31 and the pitch motor 41, the roll motor 31 drives the pitch mounting seat 43 to roll leftwards for 5 degrees through the roll speed reducer 32, and the pitch motor 41 drives the pitch output mounting plate 44 through the pitch speed reducer 42 to make opposite pitching 5 degrees of movement with the bow to dip, so that the bed frame still keeps a horizontal state of basically 0 degrees. According to the embodiment, by adopting a serial structure of rolling and pitching, the swinging of the ship body caused by surges can be effectively compensated, so that the bed body on the ship is always in a basically horizontal state, and the discomfort of passengers on the ship caused by the swinging of the ship body is reduced or eliminated.

In some embodiments, the roll angle range in which the roll motor 31 can roll left and right through the roll speed reducer 32 driving the pitch motor mount 43 is within ±30°, where ±30° refers to the range of the left roll angle and the right roll angle, and if the left roll angle is +, the right roll angle is-a. The angle of the vessel hull roll is 30 deg. close to the limit inclination angle, for which reason the roll angle range of the pitch motor mount 43 is set to within + -30 deg., so that the bedframe 1 can cover substantially all the roll angles of the vessel hull.

In some embodiments, the pitch angle range in which the pitch motor 41 drives the pitch output mounting plate 44 to pitch through the pitch speed reducer 42 is within ±12°, which is similar to the above, that is, when the pitch is plus, the pitch is-down. The pitch angle range of the pitch output mounting plate 44 is controlled within ±12°, so that the bed frame 1 can cover substantially all pitch angles of the hull.
