[0012] Compared with related technologies, the adjustable seat for dome theaters provided by this utility model has the following advantages:
[0013] Beneficial effects:
[0014] 1. By incorporating a flipping structure, when the audience needs to adjust the seat angle, an electric actuator electrically connected to an external power source is activated. The electric actuator is rotatably connected to the first connecting seat under the support plate and the second connecting seat on the bracket via fixed rods at its tail and top ends, respectively. It changes its length through its telescopic movement. Since the upper surface of the support plate is fixedly connected to the seat, and the lower surface is movably connected to the electric actuator via the first connecting seat, and the bracket is fixedly connected to the base and hinged to the support plate, the telescopic movement of the electric actuator pushes the support plate to rotate around the hinge point with the bracket, thereby causing the seat to flip and adjust its angle relative to the base. This allows the audience to adapt to both the more excited, reclining posture required for action movies and the more relaxed, semi-reclined posture required for art films, effectively improving the seat's versatility.
[0015] 2. With an adjustable structure, the rotation of the rotating rod drives the rotating block on one side of the connecting block to rotate in the rotating groove of the connecting plate. Because the side of the connecting block away from the connecting plate is fixedly connected to the leg rest, the rotation of the rotating block drives the connecting block to rotate, ultimately changing the angle of the leg rest. This meets the different needs of the audience for leg support. Users can easily adjust the angle of the seat and the position of the leg rest according to their own needs, find the most comfortable viewing posture, and effectively relieve physical fatigue caused by long-term movie watching.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes: a base 1, a seat 2, a flipping structure 3, a leg rest 4, and an adjustment structure 5. The seat 2 is mounted on top of the base 1, providing a stable support for the seat 2. The flipping structure 3 is located between the seat 2 and the base 1, allowing the user to sit on the seat 2. The flipping structure 3 includes a support plate 6, a bracket 7, and electric actuators 8. The bracket 7 is mounted on the lower surface of the support plate 6, and two sets of electric actuators 8 are mounted on one side of the bracket 7. The flipping structure 3 is mainly used to adjust the angle of the seat 2 relative to the base 1. Through the coordinated operation of the support plate 6, the bracket 7, and the electric actuators 8, the angle between the seat 2 and the base can be adjusted. The relative angle between the seat 2 and the seat 2 is as follows: a leg rest 4 is provided at one end of the seat 2, and an adjustment structure 5 is provided between the leg rest 4 and the seat 2. The adjustment structure 5 includes a connecting plate 9, a connecting block 10, a worm gear 11, and a worm 12. There are two sets of connecting plates 9. A connecting block 10 is provided on one side of the connecting plate 9. A rotating groove is opened on one side of the connecting plate 9. A cavity is opened inside the connecting plate 9. A worm gear 11 is provided inside the cavity of the connecting plate 9. A worm 12 is meshed on one side of the worm gear 11. The adjustment structure 5 is used to adjust the relative position and angle between the leg rest 4 and the seat 2, so that the leg rest 4 can be flexibly changed according to the user's needs.
[0023] In the specific implementation process, the upper surface of the support plate 6 is fixedly connected to the lower surface of the seat 2. The seat 2 can change its angle with the support plate 6. The support plate 6 plays the role of supporting and firmly connecting the seat 2. Two sets of first connecting seats 13 are fixedly connected to the lower surface of the support plate 6. The lower surface of the first connecting seat 13 is provided with a movable groove. The inner walls on both sides of the movable groove of the lower surface of the first connecting seat 13 are respectively provided with through holes.
[0024] The lower surface of the bracket 7 is fixedly connected to the upper surface of the base 1. The upper surfaces on both sides of the bracket 7 are respectively hinged to the lower surface of the support plate 6. The support plate 6 can rotate through the hinge with the bracket 7, changing the angle of the support plate 6. When the angle of the support plate 6 changes, it can drive the seat 2 to change its angle. Two sets of second connecting seats 14 are fixedly connected to the side surface of the bracket 7. The upper surface of the second connecting seat 14 is provided with a movable groove. The inner walls on both sides of the movable groove on the upper surface of the second connecting seat 14 are respectively provided with through holes.
[0025] Each of the two sets of electric actuators 8 has a fixed rod 15 fixedly connected to its tail end and top end. The fixed rods 15 at the top end of the two sets of electric actuators 8 are rotatably connected to the inner walls of the movable grooves on both sides of the lower surface of the two sets of first connecting seats 13. The fixed rods 15 at the tail end of the two sets of electric actuators 8 are rotatably connected to the inner walls of the movable grooves on both sides of the upper surface of the two sets of second connecting seats 14. Through the fixed rods 15 at the tail end and top end and the rotation of the first connecting seats 13 and the second connecting seats 14, the electric actuators 8 are electrically connected to an external power source. When the electric actuators 8 are started, they change their length through their extension and retraction, thereby pushing the bearing plate 6 to rotate around the hinge point with the bracket 7, thus realizing the angle adjustment of the seat 2 relative to the base 1.
[0026] Two sets of connecting plates 9 are fixedly connected to the outer surface of the seat 2 on the side away from the connecting block 10. The lower surface of the connecting plate 9 has a through hole, which is connected to the internal cavity of the connecting plate 9. The inner wall of the rotating groove on one side of the connecting plate 9 has a through hole, which is connected to the internal cavity of the connecting plate 9. The connecting block 10 is fixedly connected to the rotating block 16 on the side near the connecting plate 9. The rotating block 16 is rotatably disposed inside the rotating groove on one side of the connecting plate 9. A rotating rod 17 is fixedly connected to the middle of the rotating block 16. When the rotating rod 17 rotates, it can drive the rotating block 16 to rotate inside the rotating groove on one side of the connecting plate 9. When the rotating block 16 rotates, it can drive the connecting block 10 to rotate. The side of the connecting block 10 away from the connecting plate 9 is fixedly connected to the outer surface of the leg rest 4. When the connecting block 10 rotates, it can drive the leg rest 4 to change its angle.
[0027] The upper end of the worm gear 12 is rotatably connected to the top of the cavity of the connecting plate 9, and the lower end of the worm gear 12 extends through the through hole on the lower surface of the connecting plate 9 to the lower surface of the connecting plate 9. The worm gear 12 can rotate inside the through hole on the lower surface of the connecting plate 9. A servo motor 18 is provided at the lower end of the worm gear 12. The outer surface of the servo motor 18 is fixedly connected to the lower surface of the connecting plate 9. The power output end of the servo motor 18 is fixedly connected to the lower end of the worm gear 12. The servo motor 18 is electrically connected to an external power supply. When the servo motor 18 is started, the rotation of the power output end of the servo motor 18 can drive the worm gear 12 to rotate.
[0028] One end of the rotating rod 17 is rotatably connected to the inner wall of the rotating groove on one side of the connecting plate 9, and the other end of the rotating rod 17 extends through the through hole in the inner wall of the rotating groove on one side of the connecting plate 9 into the cavity of the connecting plate 9. The rotating rod 17 can rotate inside the through hole in the inner wall of the rotating groove on one side of the connecting plate 9. The end of the rotating rod 17 extending into the cavity of the connecting plate 9 is fixedly connected to the middle of the worm gear 11. The rotating rod 17 plays the role of transmitting the rotational motion of the worm gear 11, transmitting the rotational motion of the worm gear 11 to the rotating block 16 of the connecting block 10, driving the connecting block 10 and the leg support 4 to rotate relative to the connecting plate 9, thereby changing the angle of the leg support 4.
[0029] The working principle of this utility model is as follows: When the audience needs to adjust the angle of seat 2, the electric actuator 8, which is electrically connected to an external power source, is activated. The electric actuator 8 is rotatably connected to the first connecting seat 13 under the support plate 6 and the second connecting seat 14 on the bracket 7 via the fixed rod 15 at its tail end and top end, respectively. It changes its length by its own telescopic movement. Since the upper surface of the support plate 6 is fixedly connected to seat 2 and the lower surface is movably connected to the electric actuator 8 via the first connecting seat 13, and the bracket 7 is fixedly connected to the base 1 and hinged to the support plate 6, the telescopic movement of the electric actuator 8 pushes the support plate 6 to rotate around the hinge point with the bracket 7, thereby causing the seat 2 to achieve angle rotation adjustment relative to the base 1. For the adjustment of the leg rest 4, the servo motor 18, which is electrically connected to an external power source, is also activated. The power output end of the servo motor 18... The rotation drives the worm gear 12 to rotate. The upper end of the worm gear 12 rotates at the top of the cavity of the connecting plate 9, and the lower end extends through the through hole of the connecting plate 9 to the bottom and is connected to the servo motor 18. The rotation of the worm gear 12 drives the worm wheel 11, which meshes with it, to rotate in the cavity of the connecting plate 9. The rotating rod 17, which is fixedly connected to the middle of the worm wheel 11, rotates accordingly. One end of the rotating rod 17 rotates on the inner wall of the rotating groove on one side of the connecting plate 9, and the other end extends through the through hole in the inner wall of the rotating groove to the cavity and is connected to the worm wheel 11. The rotation of the rotating rod 17 drives the rotating block 16 on one side of the connecting block 10 to rotate in the rotating groove of the connecting plate 9. Because the side of the connecting block 10 away from the connecting plate 9 is fixedly connected to the leg support 4, the rotation of the rotating block 16 drives the connecting block 10 to rotate, ultimately realizing the change of the angle of the leg support 4 to meet the different needs of the audience for leg support.
