[0014] Technical effects and advantages of this application: 1. Compared with the prior art, the intelligently controlled seat chassis and the method of using the same have a balancing module installed under the base body of the seat body when the seat body is in use. When the posture of the seat body changes, the horizontal detection component above the balancing module is used to detect the horizontal angle of the seat at this time, so that the balancing module drives the counterweight component to move through the moving component, and the counterweight component is moved by the moving component. When a human body is lying on the seat body, even if the human body changes its posture on the seat body, the balancing module continuously modifies its position, thereby maintaining the stability and balance of the seat body during use.

When the horizontal position of the seat body 1 changes, the weight detection probe 202 detects the weight of the human body. At this time, when the offset angle of the base body offset level is obtained, the moving component 801 in the balancing module 8 drives the counterweight component 39 to move; Step six: When the horizontal offset is obtained, the output end of the servo motor 38 engages with the rack 4001 above the slide rail 40, and the servo motor 38 drives the box 41 of the counterweight assembly 39 to move, so that the central balancing module 8 moves, so that the seat body 1 is in horizontal balance during the lying position.

[0029] The working process of the present application is as follows: first, when a human body sits on the seat body 1, the human body's arms naturally hang down to both sides, and then the hand position fits on the outer surface of the switch extension component 4. At this time, the human body uses fingers to contact the push-pull plate 403, so that the push-pull plate 403 is pushed and pulled open, exposing the switch 402 area, and then presses the switch 402, so that the switch 402 controls the leg lifting component 5, the rotating component 13 and the adjusting component 17 inside the chassis body 2 to drive; Then when the rotating assembly 13 receives the signal, the dual-axis motor 14 runs, and one end of the dual-axis motor 14 is connected to the gear box 1401. When the dual-axis motor 14 rotates, the toothed belt 30 connected to the gear box 1401 is driven to move, so that the toothed belt 30 drives the corresponding first rotating shaft 31 to rotate. When the first rotating shaft 31 rotates, the gear installed in the first rotating shaft 31 drives the third rotating shaft 34 to rotate. At the same time, the second rotating shaft 33 cooperates with the first rotating shaft 31 to assist the third rotating shaft 34 to drive. Then the expansion plate 401 is connected to the supporting bracket 35. When the third rotating shaft 34 rotates, the third rotating shaft 34 drives the expansion plate 401 to rotate 90°, so that the switch expansion assembly 4 is parallel to the chassis body 2. Then when the adjustment component 17 receives the signal, the output end of the driving motor 18 is connected to the adjustment bracket 25, and the adjustment bracket 25 changes the output direction of the driving motor 18, so that the first rotating gear 26 connected to the adjustment bracket 25 rotates, and then when the first rotating gear 26 rotates, the first rotating gear 26 drives the docking shaft 29 to connect, and then when the docking shaft 29 rotates, the backrest fixing plate 3 connected to the docking shaft 29 rotates with the docking shaft 29, so that the angle between the backrest fixing plate 3 and the chassis body 2 changes; Then, when the leg lifting assembly 5 receives the signal, the output end of the motor is connected to the connecting shaft 12 through a gear. When the motor is driven, the connecting shaft 12 is driven by the motor to rotate, so that the leg lifting plate 9 connected to the connecting shaft 12 is driven by the connecting shaft 12 to rotate, so that the leg lifting plate 9 is level with the placement bracket 6; Then, when the switch extension component 4, the backrest fixing plate 3 and the switch extension component 4 are all leveled with the chassis body 2, when the position of the human body above the seat changes, the horizontal detection component 15 inside the placement bracket 6 detects the position of the chassis body 2, and when the positioning bracket 21 inside the horizontal detection component 15 changes at the same time due to the horizontal change, when the horizontal position of the seat body 1 changes, the weight detection probe 202 detects the weight of the human body, and when the offset angle of the base body offset level is obtained, the moving component 801 in the balancing module 8 drives the counterweight component 39 to move; When the horizontal offset is obtained, the output end of the servo motor 38 engages with the rack 4001 above the slide rail 40, and the servo motor 38 drives the box 41 of the counterweight assembly 39 to move, so that the central balancing module 8 moves, so that the seat body 1 is in horizontal balance during the lying position. The above is the working principle of this intelligent control seat chassis and its use method.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
