[0037] Specifically: there are edges around the bottom plate 1, and the elastic spacer 8 and the elastic rubber plate 11 are fixedly connected to the edges respectively. There is a mask above the elastic rubber plate 11, and the mask is connected to the edges through a hanger. The mask can be removed, cleaned and replaced, and all the assembled parts inside the spring pad can be maintained and replaced. The spacer 5 has the function of preventing the elastic spacer from contacting, wearing and producing abnormal noise with the support spring 2. The elastic spacer such as the elastic spacer 8 and the elastic rubber plate 11 has the function of connecting the support spring 2 and preventing each other from being squeezed. By setting the elastic stretching function of the elastic spacer, the independent lifting function of the support spring 2 can be improved, so that the spring pad can have a balanced supporting force for various parts of the human body, which is conducive to rest and health. After the electronic control device is energized, the fluid-driven regulating device starts to work, and the solenoid valve 31 , the circulating pump 30 starts working, and maintains a constant pressure in the high-pressure tank 27. When the forward adjustment is performed, the high-pressure gas enters the regulating assembly from the high-pressure tank 27 through the high-pressure pipe 32 and the solenoid valve 31 from the pipe port AⅠ35, drives the impeller 23 to rotate forward, and then flows back to the low-pressure tank 28 from the pipe port BⅠ37 and the solenoid valve 31 through the low-pressure pipe 33. The driving impeller 23 drives the speed change wheel 24 and the drive shaft 26 to rotate forward. The same as above, when the reverse adjustment is performed, the high-pressure gas enters the regulating assembly from the high-pressure tank 27 through the high-pressure pipe 32 and the solenoid valve 31 from the pipe port BⅡ38. After the driving impeller 23 is reversed, it flows back to the low-pressure tank 28 from the pipe port AⅡ36 and the solenoid valve 31 through the low-pressure pipe 33. The driving impeller 23 drives the speed change wheel 24 and the drive shaft 26 to rotate in the opposite direction, through the high-pressure gas and drives the regulating assembly A The driving shaft 26 on 42 drives the winding rod A 41 to rotate forward, and winds the pull rope A 15 on the winding rod A 41. The pull rope A 15 pulls the bottom end of the support spring 2 to gradually rise. After the support spring 2 is compressed, its supporting elastic force will increase. The same reverse adjustment will weaken the supporting elastic force. The contact head of the controller 25 contacts the impeller 23 and records the number of rotations of the impeller 23 and transmits it to the electronic control host 49 for programming and memory. The fluid drive regulating device is controlled by the visual function, voice control function and wireless signal receiving function of the control display to perform the regulating action. When the high-pressure gas is stopped from entering the regulating assembly, the self-locking device in the regulating assembly will automatically lock the rotation of the impeller 23. Through the above regulating process, the purpose of soft or hard adjustment of the supporting force of the spring pad is achieved. The high-pressure gas drives the driving shaft 26 on the regulating assembly B 43 to drive the winding rod B 44 to rotate forward. One end of the pull rope 17 will continue to be wound on the winding rod B 44, and the other end will exit the winding rod B 44 at the same time. 17 pulls the support rod 18 and the rubber support 19 to gradually rise. When the spring pad surface is subjected to the weight pressure and the contact distance between the spacer 5 and the rubber support 19 gradually decreases, and the contact distance gradually increases during the reverse adjustment as above. Through the above adjustment process, the purpose of adjusting the spring pad surface to a higher or lower position after being subjected to pressure is achieved. The high-pressure gas drives the drive shaft 26 on the adjustment assembly C 45 to drive the winding rod C 46 to rotate forward, and the pull rope C 47 is wound on the winding rod 46. The pull rope C 47 pulls the top of the support spring 2 to gradually descend, and the spring pad surface begins to sag.The human body will feel the spring pad's adjustment position become lower, and when the adjustment is reversed, the human body will feel the spring pad's adjustment position become higher. Through the above adjustment process, the purpose of adjusting the convexity or concavity of the spring pad surface is achieved, thereby protecting the spring pad from excessive pressure drop and damage to the internal structure. This spring pad has a simple and durable structure, is easy to operate, and is suitable for the needs of different users, especially for people who need care.
