Description

Technical Field

[0001] This invention belongs to the field of smart mattress technology, specifically a smart mattress zoned lifting and soft-firm coordination control device and method that integrates pressure sensing feedback. Background Technology

[0002] With the development of social technology, people's pursuit of high-quality sleep has gradually increased, and smart mattresses have emerged. They use internal chips and pressure sensing feedback devices to analyze the pressure on the mattress and monitor human posture, and then inflate and deflate the internal airbags in real time to adapt to the human posture.

[0003] For example, patent application CN118078067A, in the field of intelligent adjustable mattresses, discloses a variable frequency zoned pneumatic intelligent adjustable mattress and its usage method. It includes a bed frame and a mattress, with the mattress placed on the bed frame. It also includes a mounting frame and airbags. The mounting frame is located inside the bed frame and has multiple independent spaces. The airbags are placed in these independent spaces and are uniformly inflated by a first air pump. Sensors on the sensor panel locate the user's body position and transmit this information to a central control processor. The central control processor then controls the first air pump to activate, inflating the airbags at designated locations, providing immediate support to the user.

[0004] Based on the above cases and actual situations, we have found the following problems: When using this type of zoned smart mattress, the positions of the airbags in each zone are usually fixed. However, when people of different heights use it, the different zones may not correspond to the body position, affecting the user experience. If the position of the waist and hip zone is changed directly without adjusting the positions of the shoulder and back zone and the leg rest zone, gaps may appear due to volume changes during movement, or the shoulder and back zone and the leg rest zone may protrude or sink. This results in the pressure sensors receiving inaccurate initial pressure when the body lies on the smart mattress, which in turn affects the inflation and deflation adjustment of each airbag when the body posture changes. Summary of the Invention

[0005] The purpose of this invention is to provide a smart mattress zone lifting and soft-firm coordination control device and method that integrates pressure sensing feedback. By setting a sliding structure, the device can adaptively change the position of the waist and hip area while balancing the air pressure of the airbags in the shoulder and back area and the leg rest area, thereby solving the above-mentioned problems of the prior art.

[0006] To achieve the above objectives, the present invention provides an intelligent mattress zone lifting and soft-hard coordination control device that integrates pressure sensing feedback, including a mattress body and four airbags. The mattress body is divided into four zones from front to back: head and neck zone, shoulder and back zone, waist and hip zone, and leg support zone. Adjacent zones are separated by partitions. The four airbags are arranged in the four zones one by one for individual adjustment to conform to the human body. The mattress body has an adjustment component at the bottom. The adjustment component includes a sliding structure for adjusting the position of the waist and hip area to accommodate people of different heights, and two connected structures for adjusting the initial air pressure of the airbags in the shoulder and back area and the leg rest area. The sliding structure includes a servo motor and a first transmission mechanism. The servo motor controls the sliding of adjacent partition plates on the front and rear sides of the waist and hip area through the first transmission mechanism. The two sets of connecting structures are symmetrically arranged on both sides of the sliding structure. The connecting structure includes a connecting tube for connecting the airbags in the shoulder and back area and the leg-resting area, two electromagnet core blocks for controlling the opening and closing of the middle part of the connecting tube, and a generator for controlling the electromagnet core blocks to generate magnetism. The generator is connected to the first transmission mechanism through a second transmission mechanism to convert mechanical energy into electrical energy and then control the magnetic repulsion movement of the two electromagnet core blocks. When adjusting the position of the waist and hip area, the airbags in the shoulder and back area and the leg-resting area are automatically connected. During normal use, the connecting tube is closed to allow for coordinated adjustment of the zones.

[0007] In this design, considering that in the use of smart mattresses with such partitions, the airbag positions in each area are usually fixed, the different partitions may not correspond to the body position when used by people of different heights, thus affecting the user experience. If the position of the waist and hip area is changed directly without adjusting the position of the shoulder and back area and the leg rest area, gaps may appear due to volume changes during movement, or the shoulder and back area and the leg rest area may protrude or sink. This would cause the pressure sensors to receive inaccurate initial pressure when the user lies on the smart mattress, affecting the inflation and deflation of the airbags when the user changes posture. Therefore, this invention uses a sliding structure to adaptively change the position of the waist and hip area while balancing the airbags in the shoulder and back area and the leg rest area, so as to avoid affecting the initial pressure received by the pressure sensors.

[0008] In the technical solution of the present invention, the mattress body is composed of a box and a padding layer on top of the box. A bottom plate is fixed inside the box near the bottom. The dividing plate is disposed above the bottom plate. The adjacent dividing plates on the front and back sides of the waist and hip area are slidably connected to the bottom plate. The two dividing plates located on the frontmost and backmost sides of the bottom plate are fixedly connected to the bottom plate.

[0009] In this setup, a base plate is used to facilitate the installation of the upper partition plate and airbag, while also separating them from the lower adjustment components to avoid mutual interference.

[0010] In the technical solution of the present invention, the bottom plate is provided with a first reserved groove in the middle for each airbag to communicate with the corresponding air pump. The bottom plate is provided with four second reserved grooves for the connecting pipe to connect the airbag at the corresponding position. The bottom plate is provided with two sliding grooves symmetrically on the left and right. The bottom of the two middle dividing plates is symmetrically fixedly connected with two sliding plates, and the sliding plates are slidably connected to the corresponding sliding grooves.

[0011] In the technical solution of the present invention, the servo motor is fixed to the middle part of the inner wall of the front side of the housing and located below the bottom plate. The first transmission mechanism includes a lead screw fixedly connected to the output shaft of the servo motor and a crossbeam threadedly connected to the lead screw. Both ends of the crossbeam are fixed with front and rear transverse connecting rods. The front and rear ends of the connecting rods are respectively fixed to the partition plate wall on the corresponding side.

[0012] In this setup, by setting a lead screw and a crossbeam, when the servo motor drives the lead screw to rotate, it will drive the crossbeam to move, which in turn will drive the dividing plates on both sides of the waist and hip area to move synchronously through the connecting rod transmission, so that the airbags in the waist and hip area move synchronously to the appropriate position.

[0013] In the technical solution of the present invention, the middle section of the connecting pipe is connected to a contraction pipe, the diameter of the contraction pipe is smaller than the diameter of the connecting pipe, the electromagnet core block is disposed inside the contraction pipe and the outer end of the electromagnet core block is fixedly connected to a piston part for sealing the contraction pipe.

[0014] In this setup, by setting up a contraction tube and electromagnet core blocks, when two electromagnet core blocks in the same connecting tube move in opposite directions, they will leave the contraction tube, and the connecting tube will be in a connected state. When two electromagnet core blocks in the same connecting tube move towards each other, they will block the contraction tube, and the connecting tube will be in a closed state.

[0015] In the technical solution of the present invention, the inner wall of the connecting pipe is symmetrically fixed with limiting rods at the top and bottom near the middle. The limiting rods pass through the piston part on the corresponding side and are slidably connected. A spring is sleeved on the part of the limiting rod located outside the piston part, which is used to push the corresponding electromagnet core block and piston part to reset.

[0016] In this setup, a spring is used. When not adjusted, the spring force continuously pushes the electromagnet core block and piston to seal the contraction tube. During adjustment, the electromagnet core block moves in opposite directions, compressing the spring. After adjustment, the spring's restoring force pushes the electromagnet core block back to its original position, sealing the contraction tube. In the technical solution of the present invention, the same wire is wound around the two electromagnet core blocks in the same connecting pipe. The wire is wound in a coil shape on the outside of the electromagnet core blocks, and the coils wound around the two electromagnet core blocks in the same connecting pipe are in opposite directions to ensure that the two electromagnet core blocks in the same connecting pipe repel each other when energized.

[0017] In this setup, an electromagnet is formed by connecting wires and electromagnet core blocks. When two electromagnet coils are connected in series, according to the right-hand screw rule, the magnetic forces generated by the two electromagnet core blocks within the same connecting tube are mutually repulsive when energized. This causes the two electromagnet core blocks to push outwards, thus opening the contraction tube. In the technical solution of the present invention, a rocker arm is coaxially fixedly connected to the outside of the generator rotor, and the second transmission mechanism includes a first gear coaxially fixedly connected to the outer end of the rocker arm and a second gear meshing with the first gear. Two toothed plates are symmetrically fixedly connected to the bottom surface of the crossbeam, and the toothed plates mesh with the second gear on the corresponding side.

[0018] In this setup, by incorporating a first gear and a second gear, as the gear plate moves with the crossbeam, the generator is driven to produce direct current through the sequential transmission of the second gear, the first gear, and the rocker arm. This generates current in the conductors, causing the electromagnet core block to generate magnetic force. In the technical solution of the present invention, the diameter of the second gear is larger than the diameter of the first gear, so as to ensure that the first gear can rotate at a faster speed while the toothed plate drives the second gear to rotate slowly.

[0019] On the other hand, the present invention also provides a method for controlling the zoned lifting and soft-firm coordination of a smart mattress by integrating pressure sensing feedback. The method, employing the aforementioned device for controlling the zoned lifting and soft-firm coordination of a smart mattress by integrating pressure sensing feedback, includes the following steps: S1. Adjust the position of the waist and hip area according to the user's height, start the servo motor to drive the lead screw to rotate and make the crossbeam move back and forth, and then drive the dividing plates on both sides of the waist and hip area to move synchronously through the connecting rod, so that the airbags in the waist and hip area move synchronously to the appropriate position. S2. When the position of the waist and hip area changes, the volume of the airbags in the shoulder and back area and the leg-crossing area changes synchronously. During the movement of the waist and hip area, the toothed plate drives the generator to generate DC power through the second gear, the first gear and the rocker arm in sequence. At this time, the current is generated in the wire, which makes the electromagnet core block generate magnetic force as a whole. S3. When the two electromagnet core blocks in the same connecting tube generate magnetic force as a whole, they repel each other and are pushed outward, creating a gap between the piston part fixed at the outer end of the electromagnet core block and the inner wall of the contraction tube, and compressing the spring. At this time, the airbags in the shoulder and back area and the leg-crossing area are connected, so that the air pressure inside the two airbags is always in a balanced state, thus preventing the airbags in the shoulder and back area and the leg-crossing area from collapsing or inflating during the adjustment process. S4. After adjustment, the crossbeam stops moving, causing the generator to stop generating electricity. The repulsive force between the electromagnet core blocks disappears. At this time, the compressed spring, under the action of the restoring force, drives the electromagnet core block and the piston to re-seal the contraction tube, making each airbag independent of each other, which facilitates individual adjustment of the airbag.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, four areas are arranged horizontally in the front and back of the mattress body: the head and neck area, the shoulder and back area, the waist and hip area, and the leg support area. This allows each area to be individually controlled to conform to the physiological curves of the human body, thereby improving the comfort of use.

[0021] 2. In this invention, by setting a sliding structure, the position of the waist and hip area is adjusted according to the user's height during adjustment. The servo motor is started to drive the lead screw to rotate, causing the crossbeam to move back and forth. Then, through the transmission of the connecting rod, the dividing plates on both sides of the waist and hip area are moved synchronously, so that the airbags in the waist and hip area move synchronously to the appropriate position to adapt to users of different heights and improve applicability and comfort.

[0022] 3. In this invention, by setting up a connecting structure, during the movement of the waist and hip area, the generator is triggered to generate DC power, causing the two electromagnet core blocks in the same connecting tube to generate a repulsive magnetic force, which drives the piston to move outward, so that the contraction tube is in an open state, and the air pressure of the airbags in the shoulder and back area and the leg-crossing area is in a connected and balanced state. This prevents the airbags in the shoulder and back area and the leg-crossing area from collapsing or inflating during the adjustment process, thus improving the accuracy of subsequent airbag inflation and deflation adjustment.

[0024] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0025] Unless otherwise expressly stated, throughout this specification, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] Reference Figures 1-9 As shown, this embodiment provides the following technical solution: The intelligent mattress with integrated pressure sensor feedback and zoned lifting and soft-firm coordination control device includes a mattress body 100 and four airbags 108. The mattress body 100 is divided into four zones from front to back: head and neck zone 104, shoulder and back zone 105, waist and hip zone 106, and leg support zone 107. Adjacent zones are separated by a partition 103, dividing the mattress body 100 into different zones so that each zone can be controlled individually to conform to the human body. The four airbags 108 are correspondingly set in the four zones.

[0027] Pressure sensors are installed in the head and neck area 104, shoulder and back area 105, waist and hip area 106, and leg rest area 107 to detect the pressure exerted on each area when the body lies down. This pressure is then used to adjust the air pressure of the airbags 108 in different areas, achieving zoned height adjustment and coordinated firmness control. When inflated, the air pressure and top height of the airbags 108 increase, making them firmer and providing better support to the unsupported parts of the body. When deflated, the air pressure and top height of the airbags 108 decrease, making them softer and more suitable for the parts of the body that are in direct contact with the mattress body 100. The specific pressure adjustment process is existing technology in smart mattresses and will not be elaborated here.

[0028] Additionally, an adjustment component 200 is located at the bottom of the mattress body 100. The adjustment component 200 includes a sliding structure 210 for adjusting the position of the lumbar and hip area 106 to accommodate users of different heights, and two connected structures 220 for adjusting the initial air pressure of the airbags 108 in the shoulder and back area 105 and the leg rest area 107. When using this type of zoned smart mattress, the positions of the airbags 108 in each area are usually fixed. However, for users of different heights, the different zones may not correspond to the body's position, affecting the user experience. For users of different heights, the key is the position of the lumbar and hip area 106. For shorter individuals, the lumbar and hip area 106 is usually closer to the head and neck area 104; for taller individuals, the lumbar and hip area 106 is usually closer to the leg rest area 107.

[0029] The sliding structure 210 includes a servo motor 211 and a first transmission mechanism. The servo motor 211 controls the sliding of the adjacent partition plates 103 on both sides of the waist and hip area 106 through the first transmission mechanism. By setting the servo motor 211 to drive the first transmission mechanism to change the position of the waist and hip area 106, it can accommodate people of different heights, expand the range of use, and improve the user experience.

[0030] In the use of a smart mattress, the user needs to lie on it and sense their posture based on the different pressure points in various areas. This allows the airbags 108 to inflate and deflate accordingly, ensuring that each airbag 108 effectively conforms to the body structure for support. If the position of the lumbar and hip area 106 is changed directly without adjusting the positions of the shoulder and back area 105 and the leg rest area 107, gaps will appear due to volume changes during movement, or the shoulder and back area 105 and the leg rest area 107 will protrude or sink. This will cause the pressure sensors to receive inaccurate initial pressure when the user lies on the smart mattress, affecting the inflation and deflation of the airbags 108 when the user's posture changes. Therefore, this invention solves this problem by setting up a connecting structure 220.

[0031] Two sets of connecting structures 220 are symmetrically arranged on both sides of the sliding structure 210. The connecting structure 220 includes a connecting tube 221 for connecting the airbags 108 in the shoulder and back area 105 and the leg rest area 107, two electromagnet core blocks 223 for controlling the opening and closing of the middle part of the connecting tube 221, and a generator 225 for controlling the electromagnet core blocks 223 to generate magnetism. The generator 225 is connected to the first transmission mechanism through a second transmission mechanism to convert mechanical energy into electrical energy, thereby controlling the two electromagnet core blocks 223 to move by magnetic repulsion. When adjusting the position of the waist and hip area 106, the airbags 108 in the shoulder and back area 105 and the leg rest area 107 are connected so that all airbags 108 are initially at the same horizontal height to ensure lying comfort. During normal use, the connecting tube 221 is closed to allow for zoned coordinated adjustment.

[0032] During adjustment, the first transmission mechanism drives the generator 225 to generate electricity through the second transmission mechanism, which in turn causes the electromagnet core block 223 to generate magnetic force and repel each other, opening the connecting pipe 221. This allows the airbags 108 in the shoulder and back area 105 and the leg area 107 to connect with each other, and the volume of the airbags 108 in the shoulder and back area 105 and the leg area 107 changes by the same amount. This ensures that the airbags 108 in the shoulder and back area 105 and the leg area 107 are always in a balanced state and will not dent or bulge, thus affecting subsequent use.

[0033] It should be noted that the generator 225 is specifically a hand-cranked DC generator, which typically has a small induced electromotive force to avoid excessive current and potential danger, and is also relatively inexpensive.

[0034] Please see Figures 1-3 As shown, the mattress body 100 consists of a housing 102 and a padding layer 101 on top of the housing 102. A base plate 109 is fixed inside the housing 102 near the bottom. Dividing plates 103 are positioned above the base plate 109. Adjacent dividing plates 103 on the front and rear sides of the lumbar and hip area 106 are slidably connected to the base plate 109. Two dividing plates 103 located at the front and rearmost sides of the base plate 109 are fixedly connected to it. The base plate 109 facilitates the installation of the upper dividing plates 103 and airbags 108, while also separating them from the lower adjustment assembly 200 to avoid mutual interference.

[0035] Please see Figure 4 As shown, the base plate 109 has a first reserved groove 1091 in the middle for each airbag 108 to connect with the corresponding air pump. The base plate 109 has four second reserved grooves 1092 for the connecting pipe 221 to connect to the corresponding airbag 108. The base plate 109 has two sliding grooves 1093 symmetrically arranged on the left and right sides, and two sliding plates 1031 are symmetrically fixedly connected to the bottom of the two middle dividing plates 103. The sliding plates 1031 are slidably connected to the corresponding sliding grooves 1093.

[0036] Please see Figure 5 As shown, the servo motor 211 is fixed to the middle of the front inner wall of the housing 102 and located below the bottom plate 109. The first transmission mechanism includes a lead screw 212 coaxially fixedly connected to the output shaft of the servo motor 211 and a crossbeam 213 threadedly connected to the lead screw 212. The rear end of the lead screw 212 is mounted on the bottom surface of the housing 102 via a bracket, and the lead screw 212 is rotatably connected to the bracket. Both ends of the crossbeam 213 are fixed with front and rear transverse connecting rods 214, and the front and rear ends of the connecting rods 214 are respectively fixed to the wall of the corresponding partition plate 103. By setting the lead screw 212 and the crossbeam 213, when the servo motor 211 drives the lead screw 212 to rotate, it will drive the crossbeam 213 to move, and then drive the partition plates 103 on both sides of the waist and hip area 106 to move synchronously through the connecting rods 214, so that the airbags 108 in the waist and hip area 106 move synchronously to the appropriate position.

[0037] Please see Figures 6-7 As shown, a contraction tube 222 is connected to the middle section of the connecting pipe 221, and the diameter of the contraction tube 222 is smaller than the diameter of the connecting pipe 221. An electromagnet core block 223 is disposed inside the contraction tube 222, and a piston is fixedly connected to the outer end of each electromagnet core block 223 for sealing the contraction tube 222. By setting up the contraction tube 222 and the electromagnet core block 223, when two electromagnet core blocks 223 within the same connecting pipe 221 move in opposite directions, they will leave the contraction tube 222, at which point the connecting pipe 221 is in a connected state. When two electromagnet core blocks 223 within the same connecting pipe 221 move towards each other, they will seal the contraction tube 222, at which point the connecting pipe 221 is in a closed state.

[0038] Furthermore, symmetrical limit rods 2231 are fixed to the inner wall of the connecting pipe 221 near the middle. The limit rods 2231 pass through the corresponding side piston parts and are slidably connected. A spring 2232 is sleeved on the outer part of the limit rod 2231, which is used to push the corresponding side electromagnet core block 223 and piston parts to reset. By setting the spring 2232, when not adjusted, the spring force of the spring 2232 continuously pushes the electromagnet core block 223 and piston parts to seal the contraction tube 222. When adjusting, the electromagnet core block 223 moves in opposite directions, compressing the spring 2232. After adjustment, the restoring force of the spring 2232 will push the electromagnet core block 223 to reset and seal the contraction tube 222 again.

[0039] Please see Figures 7-8 As shown, the same wire 224 is wound around the two electromagnet core blocks 223 inside the same connecting pipe 221. The wire 224 is wound in a coil shape outside the electromagnet core blocks 223, and the coils wound around the two electromagnet core blocks 223 inside the same connecting pipe 221 are wound in opposite directions.

[0040] An electromagnet is formed by setting the wire 224 and the electromagnet core block 223. When the two electromagnet coils are connected in series, according to the right-hand screw rule, the magnetic forces generated by the two electromagnet core blocks 223 in the same connecting tube 221 are mutually repulsive when energized. This causes the two electromagnet core blocks 223 to push outward and open the contraction tube 222.

[0041] Please see Figure 9 As shown, a rocker arm 226 is coaxially fixedly connected to the outer side of the rotor of the generator 225. The second transmission mechanism includes a first gear 227 coaxially fixedly connected to the outer end of the rocker arm 226 and a second gear 228 meshing with the first gear 227. Two toothed plates 229 are symmetrically fixedly connected to the bottom surface of the crossbeam 213, and the toothed plates 229 mesh with the corresponding second gear 228.

[0042] By setting up a first gear 227 and a second gear 228, when the toothed plate 229 moves with the crossbeam 213, the generator 225 is driven to generate direct current through the sequential transmission of the second gear 228, the first gear 227, and the rocker arm 226. At this time, current is generated in the conductor 224, causing the electromagnet core block 223 to generate magnetic force as a whole. The rocker arm 226 drives the generator 225 to rotate, cutting magnetic field lines to generate induced electromotive force, which in turn generates induced current. This is the basic principle of a hand-cranked DC generator, which is an existing technology and will not be elaborated here.

[0043] It should be noted that the diameter of the second gear 228 is larger than that of the first gear 227, so as to ensure that the first gear 227 can rotate at a faster speed while the second gear 228 is slowly rotated by the toothed plate 229, so as to ensure that the first gear 227 drives the rocker arm 226 to rotate at a faster speed, so that the DC power generated by the generator 225 can generate a sufficiently large magnetic field in the electromagnet core block 223.

[0044] The present invention discloses a method for controlling the zonal lifting and soft / firm adjustment of a smart mattress that integrates pressure sensor feedback. This method, employing the aforementioned device for controlling the zonal lifting and soft / firm adjustment of a smart mattress that integrates pressure sensor feedback, includes the following steps: S1. Adjust the position of the waist and hip area 106 according to the user's height, start the servo motor 211 to drive the lead screw 212 to rotate and cause the crossbeam 213 to move back and forth, and then drive the dividing plates 103 on both sides of the waist and hip area 106 to move synchronously through the connecting rod 214, so that the airbags 108 in the waist and hip area 106 move synchronously to the appropriate position. S2. When the position of the waist and hip area 106 changes, the volume of the airbag 108 in the shoulder and back area 105 and the airbag 108 in the leg-crossing area 107 changes synchronously. During the movement of the waist and hip area 106, the toothed plate 229 drives the generator 225 to generate DC power through the second gear 228, the first gear 227 and the rocker arm 226 in sequence. At this time, the current is generated in the wire 224, so that the electromagnet core block 223 generates magnetic force as a whole. S3. When the two electromagnet core blocks 223 in the same connecting tube 221 generate magnetic force as a whole, they repel each other and are pushed outward, so that a gap appears between the piston part fixed at the outer end of the electromagnet core block 223 and the inner wall of the contraction tube 222, and the spring 2232 is compressed. At this time, the airbags 108 in the shoulder and back area 105 and the leg area 107 are connected, so that the air pressure inside the two airbags 108 is always in a balanced state, and thus the airbags 108 in the shoulder and back area 105 and the leg area 107 will not collapse or bulge during the adjustment process. S4. After adjustment, the crossbeam 213 stops moving, causing the generator 225 to stop generating electricity. The repulsive force between the electromagnet core blocks 223 disappears. At this time, the compressed spring 2232 will drive the electromagnet core block 223 and the piston to re-seal the contraction tube 222 under the action of the restoring force, so that each airbag 108 is independent of each other, making it convenient to adjust the airbag 108 individually.

10. A method for controlling the zoned lifting and soft-firm coordination of an intelligent mattress by integrating pressure sensor feedback, comprising the intelligent mattress zoned lifting and soft-firm coordination control device by integrating pressure sensor feedback as described in claim 9, characterized in that, Includes the following steps: S1. Adjust the position of the waist and hip area (106) according to the user's height, start the servo motor (211) to drive the lead screw (212) to rotate and make the crossbeam (213) move back and forth, and then drive the dividing plates (103) on both sides of the waist and hip area (106) to move synchronously through the connecting rod (214), so that the airbags (108) in the waist and hip area (106) move synchronously to the appropriate position. S2. When the position of the waist and hip area (106) changes, the volume of the airbag (108) in the shoulder and back area (105) and the airbag (108) in the leg-crossing area (107) changes synchronously. During the movement of the waist and hip area (106), the toothed plate (229) drives the generator (225) to generate DC power through the second gear (228), the first gear (227) and the rocker arm (226) in sequence. At this time, current is generated in the wire (224), so that the electromagnet core block (223) generates magnetic force as a whole. S3. When the two electromagnet core blocks (223) in the same connecting tube (221) generate magnetic force as a whole, they repel each other and are pushed outward, so that a gap appears between the piston part fixed at the outer end of the electromagnet core block (223) and the inner wall of the contraction tube (222), and the spring (2232) is compressed. At this time, the airbags (108) in the shoulder and back area (105) and the leg area (107) are connected, so that the air pressure inside the two airbags (108) is always in a balanced state, so that the airbags (108) in the shoulder and back area (105) and the leg area (107) will not collapse or bulge during the adjustment process. S4. After adjustment, the crossbeam (213) stops moving, causing the generator (225) to stop generating electricity. The repulsive force between the electromagnet core blocks (223) disappears. At this time, the compressed spring (2232) will drive the electromagnet core blocks (223) and the piston to re-seal the contraction tube (222) under the action of the restoring force, so that each airbag (108) is independent of each other, making it convenient to adjust the airbag (108) individually.
