Abstract
Description
Technical Field
[0001] This utility model belongs to the field of household products, and specifically relates to a spring pad with adjustable connecting body tension. Background Technology
[0002] Currently, most spring mattresses and sofa cushions on the market use support springs as the main elastic support components. When assembling and connecting the top of the support springs, traditional methods such as snap-fit connections, cocoon spring insertion connections, and squeeze connections are still used to assemble the spring mattresses. Mattresses and sofa cushions made with these processes cannot effectively utilize the independent support function of the support springs during use, and will lose the good independent support function of the spring mattress. Therefore, it is necessary to cover the support springs with multiple elastic support layers of different materials, such as sponge layers, coconut fiber layers, technical synthetic elastic layers, latex cotton layers, etc. After a period of use, the added support layers will lose their support elasticity, resulting in unsatisfactory elastic support effect. The main reason for this is that the connection structure at the top of the support spring is unreasonable, which cannot effectively utilize the independent support function of the support spring, and the connection structure at the top of the support spring cannot be adjusted to increase or decrease the tension.

The pressure sensor 36 is connected to the electrical control box 8. A camera 37 and an intelligent controller 38 are connected to the electrical control box 8. The camera 37 is connected to the base plate 1. A mask 39 is covered above the elastic support pad 35; a partition slide plate 40 is provided between adjacent combined blocks 11.

Adjacent partition slide plates 40 are connected by an elastic pull rope 42.The hexagonal transmission rod 9 has a bidirectional pressure regulating cylinder 44 in its middle. The hexagonal transmission rod 9 includes an upper hexagonal rod A9-1 and a lower hexagonal rod B9-2. The bidirectional pressure regulating cylinder 44 is fitted with a piston ring 45, which is connected to a piston 46. The top of the bidirectional pressure regulating cylinder 44 is fitted with a hexagonal hole cap 33. After connecting to the piston 46, the hexagonal rod A9-1 passes through the hexagonal hole cap 33 and is connected to a universal joint 23. The control frame 22 is rotatably connected to the bidirectional pressure regulating cylinder 44 via a control wheel 32.

[0010] Specifically, after powering on the electrical control box 8, the user inputs a setting program into the intelligent control unit 38. Simultaneously, after receiving the signal transmitted by the pressure sensor 36, the servo motors 31 in different areas begin to operate. The pressure sensor 36 detects the pressure on the elastic pads 35 in different areas and transmits this information to the intelligent control unit 38. The intelligent control unit 38 automatically controls the rotation of each servo motor 31 according to the set program. The torque clutch 30 automatically disengages the servo motor 31 from the drive wheel 29 when the torque of the servo motor 31 driving the drive wheel 29 is too high, thus acting as a clutch and protecting the various components of the transmission structure from damage. The camera 37 is used... To observe whether the internal assembly and connecting parts of the spring pad are working properly, any abnormalities can be detected and addressed promptly through the display function of the intelligent control unit 38. The transmission belt 28 drives the drive wheel 25 to rotate via the drive wheel 29. The drive wheel 25 drives the hexagonal transmission rod 9 to rotate via the hexagonal connection hole 26. Simultaneously, the hexagonal transmission rod 9 can slide freely up and down within the hexagonal connection hole 26. The hexagonal transmission rod 9 is controlled by the control wheel 32 to prevent excessive tilting and allows lateral swaying within a suitable range. This swaying helps improve the comfort and support effect of the spring pad. The hexagonal transmission rod 9 is connected to the adjusting screw 18 via the universal joint 23. The universal joint 23 enhances the softness and comfort of the spring pad. In terms of support effect, when the hexagonal transmission rod 9 drives the adjusting screw 10 to rotate, the adjusting nut 19 will cause one end of the tension spring 20 to rise or fall. The tension spring 20 will then exert a varying degree of tension on the connecting soft strap 16. Therefore, the connecting soft strap 16 will exert a varying degree of connecting tension on the two adjacent assembly blocks 11, thus adjusting the combined connecting body 6. This achieves the function of adjusting the combined connecting body 6 to provide soft or firm support to different areas of the spring pad. This function is beneficial for providing more reasonable and comfortable support to different parts of the user's body. Simultaneously, this adjustment process can also achieve the good effect of adjusting the independent support function of the supporting spring 5. When using the spring pad, the body faces the mask... Pressure is generated by the mask 39. The elastic support pad 35 is subjected to the downward pressure of the mask 39 and the upward lifting force of the combined block 11. When the downward pressure and the upward lifting force reach equilibrium, the combined block 11 stops descending. The upward lifting force of the combined block 11 is generated by the superposition of the supporting elastic force of the support spring 5 and the bearing force of the combined connecting body 6. The bearing force of the combined connecting body 6 can be adjusted by the intelligent adjustment device. When the combined block 11 descends too much, the limiting 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 into two sections, namely the upper hexagonal rod A9-1 and the lower hexagonal rod B9-2.A bidirectional 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 achieved through the smooth connection between the piston ring 45 and the inner wall of the bidirectional pressure regulating cylinder 44, allowing for smooth and free lifting and lowering. After adding lubricating oil to the bidirectional pressure regulating cylinder 44, the piston ring 46 can maintain long-term wear-free free lifting and lowering movement. Under the combined action of the lower hexagonal rod B9-2 and the supporting bearing 48, the bidirectional pressure regulating cylinder 44 can rotate freely. The bidirectional pressure regulating cylinder 44 is controlled by the control wheel 32 to prevent excessive tilting and allows for lateral swaying within a suitable range. When the piston 46 descends to the bottom of the bidirectional pressure regulating cylinder 44, it stops descending. This process protects the intelligent transmission adjustment device 3 from damage. Therefore, the addition of a bidirectional... The pressure regulating cylinder 44 and its components reduce wear on the hexagonal connecting holes 26 on the drive wheel 25 caused by the up-and-down movement of the hexagonal transmission rod, and improve the smoothness of the hexagonal transmission rod's lifting and lowering, thus enhancing the soft support effect of the spring pad. The separating slide plate 40 between adjacent assembly blocks 11 reduces the manufacturing size of the assembly blocks 11 and minimizes mutual wear between adjacent assembly blocks 11, further improving the soft support effect of the spring pad. In summary, through the intelligent coordination of the intelligent adjustment device 3 and the intelligent control unit 38, the problem of a more scientific and reasonable tension connection between the upper assembly connecting body 6 of the elastic support body 2 and the top of the support spring 5 is completely solved. This structural solution can be used on spring mattresses or sofa cushions, catering to the specific needs of different consumers.
