[0021] like Figure 1-3 As shown, the immersive ring-screen theater large experience platform 4 includes a central axis 5, a turntable 13, a servo motor 8, four cylinders 2 that can be individually electrically controlled and a platform 4. The central axis 5 is fixed on the ground through a mounting seat 11, and the axis position of the turntable 13 is rotatably connected to the central axis 5 through a roller bearing 15. The outer wall of the turntable 13 is provided with a toothed belt 1, and the servo motor 8 is set on the ground through a support frame 10. The output end of the servo motor 8 is provided with a toothed wheel 9 matching the toothed belt, and the toothed wheel 9 is meshed with the toothed belt 1. Four cylinders 2 are arranged in a ring matrix on the upper surface of the turntable 13 with the axis of the turntable 13 as the center, and a universal joint ball bearing 7 is provided at the telescopic end of the cylinder 2. A movable part 3 is provided at the position of the universal joint ball bearing 7 on the bottom surface of the platform 4. The movable end of the movable part 3 is slidably connected to the ball head in the universal joint ball bearing 7, and the movable part 3 includes a plurality of sliders 32 and a linear slide rod 3 1. Multiple sliders 32 are fixedly connected to the bottom surface of the platform 4, and the linear slide 31 rotates and passes through the slider 32. The ball head in the universal joint ball bearing 7 is slidably connected to the linear slide 31, and the axes of the two adjacent linear slides 31 at the bottom of the platform 4 are perpendicular to each other; the toothed belt 1 is a wide belt made of polyurethane, which is fixed to the side surface of the turntable 13 by glue and turntable nails; steel wire is arranged inside the toothed belt 1; at least 8 load-bearing wheels 14 are evenly arranged at the bottom of the turntable 13; multiple support columns 12 are arranged on the turntable 13, and static bearing platforms 6 are arranged on multiple support columns 12, which can be used to support the platform 4 in a non-working state; the turntable 13 is made of steel plate and is hollow in design; the servo motor 8 and the toothed wheel 9 are designed in four groups and are evenly distributed on one circle of the toothed belt 1, and the toothed wheels 9 are respectively meshed and connected with the toothed belt 1; the platform 4 is made of a steel structure as a skeleton and a flat plate as a covering surface.

[0022] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0023] According to the instruction manual Figure 1-3 It can be seen that when the present invention is used, the servo motor 8 rotates to drive the toothed wheel 9 to rotate. Since the toothed wheel 9 is meshed with the toothed belt 1 provided on the side surface of the turntable 13, and the turntable 13 is rotatably connected to the central shaft 5 on the mounting seat 11 through the roller bearing 15, the toothed wheel 9 can drive the turntable 13 to rotate. Since the platform 4 is provided on the turntable 13 through the four cylinders 2, it can drive the platform 4 to rotate, thereby causing the person on the platform 4 to rotate; since the four cylinders 2 that can be individually electrically controlled are arranged in a ring matrix on the upper surface of the turntable 13 with the axis of the turntable 13 as the center, and the cylinders 2 A universal joint ball bearing 7 is provided at the telescopic end, and a movable part 3 is provided on the bottom surface of the platform 4 at a position corresponding to the universal joint ball bearing 7. The movable end of the movable part 3 is slidably connected to the ball head in the universal joint ball bearing 7. Therefore, by adjusting the operation of the four cylinders 2, the platform 4 can be raised and lowered and tilted or performed simultaneously, so that the people on the platform 4 can be raised or lowered, that is, the feeling of being overweight or weightless. Similarly, when tilting, the spectators on the platform 4 are given a feeling of tilting. If the telescopic ends of the four cylinders 2 work rapidly and alternately, the spectators on the platform 4 can also have a feeling similar to vibration. Here, the universal joint ball head bearing 7 is the existing technology and can rotate at any angle. The movable part 3 includes multiple sliders 32 and linear slides 31. The multiple sliders 32 are fixedly connected to the bottom surface of the platform 4. The linear slide 31 rotates through the slider 32, that is, the linear slide 31 can rotate relative to the slider 32. The ball head in the universal joint ball head bearing 7 is slidably connected to the linear slide 31, that is, they can move horizontally with each other. The axes of the two adjacent linear slides 31 at the bottom of the platform 4 are perpendicular to each other. This design can ensure that when the platform 4 is tilted, compensation is given to the connection between the telescopic ends of the cylinder 2 to ensure normal operation. Figure 1 The middle wide arrow represents the movable direction of the universal joint ball bearing 7, and the direction arrow on the servo motor 8 represents the rotation direction of the output end of the servo motor 8. The utility model drives the turntable 13 to rotate through the servo motor 8, thereby driving the platform 4 to rotate. The four cylinders 2 distributed in a ring matrix drive the platform 4 to rise and fall, tilt, and rapidly rise and fall alternately, thereby generating vibration or a superposition of at least two of the above effects, so that the audience can get a real experience effect when watching the circular screen, making the displayed content more realistic, vivid, lively, and more appealing, improving the audience's experience and sense of reality, and achieving a real dynamic experience through mechanical means. The specific actions can be achieved through program control of the cylinders 2 and the servo motor 8. Program control can be achieved through existing technology.

[0024] Among them, the toothed belt 1 adopts a wide belt made of polyurethane, which is fixed to the side surface of the turntable 13 by glue and turntable nails. Steel wire can also be arranged inside the toothed belt 1 to increase the transmission strength. The design of the toothed belt 1 can reduce the manufacturing difficulty, reduce the overall weight, improve the installation convenience, and eliminate the meshing noise.

[0025] Among them, at least 8 load-bearing wheels 14 are evenly arranged at the bottom of the turntable 13, which are used to support the turntable 13 and the platform 4 on the turntable 13 to ensure that the device can be stable during rotation and other activities. The size and number of the load-bearing wheels 14 match the load-bearing load.

[0026] Among them, multiple support columns 12 are provided on the turntable 13, and static bearing platforms 6 are provided on the multiple support columns 12. The static bearing platform 6 can be used to support the platform 4 in a non-working state. When not working, the cylinder 2 stops working and the static bearing platform 6 is used to support the platform 4 to ensure stability.

[0027] The turntable 13 is made of hollow steel plate, ensuring support strength while reducing weight and facilitating production. One method for manufacturing the turntable 13 involves stacking four large channel steels with a laser-cut center hole and two circular arcs at each end to form the hub. The wheel circle is then cut from steel plate, and multiple pieces are welded together to form the disk surface. Steel belts are then used to wrap around the circular ends, and finally, a toothed belt is secured to the steel belt.

[0028] Among them, four groups of servo motors 8 and toothed wheels 9 are designed and evenly distributed in one circle of the toothed belt 1. The toothed wheels 9 are respectively engaged with the toothed belt 1 to make up for the insufficient wrap angle with the toothed belt 1 and improve the stability of the transmission. Of course, 4-6 groups of servo motors 8 and toothed wheels 9 can be set, and the turntable 13 is designed according to the actual size.

[0029] Among them, the platform 4 is made of a steel structure as a skeleton and a flat plate as a covering surface, which ensures the supporting strength while reducing the weight and facilitating production.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
