The drive wheel 25 is connected to the driving wheel 29 through a transmission belt 28. The driving wheel 29 is connected to the servo motor 31 through a torque clutch 30. The servo motor 31 is connected to the electric control box 8. A control frame 22 is provided on the base plate 1. The control frame 22 is slidably connected to the hexagonal transmission rod 9 through the control wheel 32. The servo motor 31 and the drive The driving wheels 25 are respectively connected to the bottom plate 1; an elastic support pad 35 is provided above the combination block 11, and a pressure sensor 36 is provided on the elastic support pad 35. The pressure sensor 36 is connected to the electric control box 8, and the electric control box 8 is connected to a camera 37 and an intelligent control machine 38. The camera 37 is connected to the bottom plate 1, and the elastic support pad 35 is covered with a mask 39; a partition slide 40 is provided between adjacent combination blocks 11, and a soft belt hole 41 is provided on the partition slide 40. The connecting soft belt 16 passes through the soft belt hole 41 and is connected to the soft belt pulley 15 on the adjacent combination block 11. Adjacent partition slides 40 are connected by elastic pulleys 42;A bidirectional pressure regulating cylinder 44 is provided in the middle of the hexagonal transmission rod 9. The hexagonal transmission rod 9 comprises an upper hexagonal rod A9-1 and a lower hexagonal rod B9-2. A piston ring 45 is mounted on the bidirectional pressure regulating cylinder 44, which is connected to a piston 46. A hexagonal hole cover 33 is mounted on the top of the bidirectional pressure regulating cylinder 44. After the hexagonal rod A9-1 is connected to the piston 46, it passes through the hexagonal hole cover 33 and is connected to the universal joint 23. The control frame 22 is rotationally connected to the bidirectional pressure regulating cylinder 44 via the control wheel 32. The bottom end of the bidirectional pressure regulating cylinder 44 is rotationally connected to a support bearing 48, which is connected to the base plate 1 via the connecting hole 12. The hexagonal rod B9-2 is connected to the bottom end of the bidirectional pressure regulating cylinder 44, passes through the support bearing 48, and is connected to the drive wheel 25.
[0010] Specifically, after the electric control box 8 is powered on, the user inputs the setting program into the intelligent control machine 38. At the same time, after the intelligent control machine 38 receives the signal transmitted by the pressure sensor 36, the servo motors 31 set in different areas start to work. The pressure sensor 36 is used to detect whether the pressure on the elastic support pad 35 in different areas is large or small and transmits it to the intelligent control machine 38. The intelligent control machine 38 will automatically control the rotation of each servo motor 31 according to the set program. The function of the torque clutch 30 is that when the torque of the servo motor 31 driving the driving wheel 29 is too large, the torque clutch 30 will automatically separate the servo motor 31 from the driving wheel 29, that is, it plays the role of clutch and is used to protect the various components of the transmission structure from damage. The camera 37 is used In order to observe whether the various combined connecting parts structure inside the spring pad is working normally, when an abnormal situation occurs, it can be discovered and maintained in time through the screen display function of the intelligent control machine 38. The transmission belt 28 drives the driving wheel 25 to rotate through the active wheel 29, and the driving wheel 25 drives the hexagonal transmission rod 9 to rotate through the hexagonal connection hole 26. At the same time, the hexagonal transmission rod 9 can slide freely up and down in the hexagonal connection hole 26. The hexagonal transmission rod 9 will be controlled by the control wheel 32 and will not tilt too much, and lateral shaking is allowed within a suitable range. This shaking is conducive to improving the comfortable support effect of the spring pad. The hexagonal transmission rod 9 is connected to the adjusting screw 18 through the universal joint 23. The universal effect of the direction joint 23 can improve the softness and comfort of the spring pad. Support effect, when the hexagonal transmission rod 9 drives the adjusting screw 10 to rotate, the adjusting nut 19 will drive one end of the tension spring 20 to rise or fall, and the tension spring 20 will produce a larger or smaller tension on the connecting soft belt 16, so the connecting soft belt 16 will produce a larger or smaller connection tension on the two adjacent combined blocks 11, that is, the adjustment effect of the adjustment combination connector 6, which achieves the adjustment function of adjusting the combination connector 6 to produce soft support or hard support for different areas of the spring pad. This function is conducive to a more reasonable and comfortable support effect for different parts of the user's body. At the same time, this adjustment process can also achieve the good effect of adjusting the independent support function of the support spring 5. When using the spring pad, the human body is against the mask. 39 generates pressure, and the elastic support pad 35 is subjected to the downward pressure of the mask 39 and the upward support force of the assembly block 11. When the downward pressure and the upward support force reach a balance, the assembly block 11 stops descending. The upward support force of the assembly block 11 is generated by the superposition of the supporting elastic force of the support spring 5 and the supporting force of the assembly connector 6. The supporting force of the assembly connector 6 can be adjusted to a larger or smaller value by the intelligent adjustment device. When the assembly block 11 descends too much, the limit support 33 in the middle of the hexagonal transmission rod 9 will contact the control wheel 32, controlling the hexagonal transmission rod 9 to stop descending. This process can protect the intelligent transmission adjustment device 3 from damage. The hexagonal transmission rod 9 is set to two upper and lower sections, namely the upper hexagonal rod A9-1 and the lower hexagonal rod B9-2.A two-way pressure regulating cylinder 44 is connected between the upper and lower hexagonal rods. The connection between the upper hexagonal rod A9-1 and the piston 46 can be smoothly connected through the piston ring 45 and the inner wall of the two-way pressure regulating cylinder 44, and can be smoothly lifted and lowered. After lubricating oil is added to the two-way pressure regulating cylinder 44, the piston ring 46 can maintain a long-term wear-free free lifting movement. The two-way pressure regulating cylinder 44 can rotate freely under the joint action of the lower hexagonal rod B9-2 and the supporting bearing 48. The two-way pressure regulating cylinder 44 is controlled by the control wheel 32 so that it will not tilt too much and is allowed to produce lateral shaking within a suitable range. When the piston 46 drops to the bottom of the two-way pressure regulating cylinder 44, it stops falling. This process can protect the intelligent transmission adjustment device 3 from damage, so the two-way pressure regulating cylinder 44 is added. The pressure-regulating cylinder 44 and its various components reduce wear on the hexagonal connection holes 26 on the drive wheel 25 caused by the up-and-down motion of the hexagonal drive rod, and improve the smoothness of the hexagonal drive rod's ascent and descent, thereby enhancing the spring pad's soft support. The separating slides 40 provided between adjacent modular blocks 11 reduce the size of the modular blocks 11 and reduce mutual wear between adjacent modular blocks 11, thereby enhancing the spring pad's soft support. In summary, the intelligent coordination of the intelligent adjustment device 3 and the intelligent control unit 38 completely solves the problem of more scientifically and rationally connecting the upper modular connector 6 of the elastic support body 2 to the top of the support spring 5. This structural solution can be used on spring mattresses or sofa cushions, meeting the specific needs of different consumers.
