A second mattress base layer is located inside the mattress body on the side of the adhesive, and a first mattress base layer is located inside the mattress body on the side of the adhesive away from the second mattress base layer. The massage areas on these mattresses are fixed to the surface of the mattress body. This may cause some discomfort to users when they are resting normally on the mattress without needing a massage, due to the presence of these areas. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive support mattress. This invention achieves flexible switching between support and massage functions by controlling the lifting and lowering of the second support block, and the height of the second support block is adjustable, offering high flexibility.

[0004] The technical solution of this utility model is as follows: an adaptive support mattress, comprising a mattress body, a groove in the middle of the mattress body, a base plate in the groove, a plurality of first support columns on the base plate, and a first support block at the upper end of each first support column; a plurality of rotating seats symmetrically arranged on the base plate, with protruding columns rotatably connected between the rotating seats; a motor is provided on the outside of each rotating seat, and the output end of the motor is fixedly connected to the protruding column; a movable plate is provided at the upper end of each protruding column, and the movable plate is slidably connected to the first support column; a plurality of second support columns are fixedly connected to the movable plate, and a second support block is provided at the upper end of each second support column; a contact soft layer is provided at the upper end of each first support block.

[0005] In the aforementioned adaptive support mattress, the upper surface of the contact soft layer is covered with an upper fabric layer; the lower surface of the base plate is covered with a lower fabric layer, and a side fabric layer connects the edge of the lower fabric layer to the edge of the upper fabric layer.

[0006] In the aforementioned adaptive support mattress, the length of the first support column is longer than the length of the second support column.

[0007] In the aforementioned adaptive support mattress, when the movable board is raised to its highest position, the second support block is higher than the first support block; when the movable board is lowered to its lowest position, the surface of the second support block is level with the surface of the first support block.

[0008] The aforementioned adaptive support mattress includes a first pad layer disposed above a first support block, a second pad layer disposed above the first pad layer, and a third pad layer disposed above the second pad layer.

[0009] The aforementioned adaptive support mattress has a first layer made of EVA high-elasticity foam; a second layer made of activated carbon; and a third layer made of slow-rebound memory foam made of polyurethane foam.

[0010] In the aforementioned adaptive support mattress, the first support block and the second support block have the same shape, both including a hemispherical body, and a planar support part is provided above the hemispherical body.

[0011] Compared with the prior art, this utility model has the following beneficial effects: In this utility model, both the first support block and the second support block are set in the groove in the middle of the mattress body, and their positions correspond to the back, waist and hip areas of the human body. They are specifically designed to support and massage these areas, adapting to the needs of the human body's physiological curves. When the user does not need massage, the moving plate is in its lowest position, at which time the height of the second support block is the same as that of the first support block, and it can be used as a normal mattress. When the protrusion causes the moving plate to rise, making the second support block higher than the first support block, the height of the contact layer at the first support block is lower than the height of the contact layer at the second support block. This structure can enhance the air circulation of the back, reduce sweat accumulation, and improve sleep comfort. When a user needs a massage, the motor on the outside of the rotating seat is activated. The motor output drives the convex column to rotate, and the protruding part of the convex column pushes the moving plate to slide upward along the first support column. This, in turn, drives the second support block to rise synchronously through the second support column, lifting the corresponding area of ​​the contact soft layer. This allows the second support block to fit against the user's back, waist, and buttocks, achieving a massage effect through the reciprocating motion of the motor. By adjusting the rotation angle of the convex column driven by the motor, the rising amplitude of the moving plate can be precisely controlled, thereby adjusting the lifting height of the second support block to suit different users' needs for massage intensity. This allows for flexible switching between support and massage functions, balancing comfort and practicality. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0015] Example: An adaptive support mattress, as shown in Figures 1-4, includes a mattress body 1. The mattress body 1 is made of high-density polyurethane foam with a density of 40D, providing both support and flexibility, and offering a stable foundation for the overall structure. A groove 2 is provided in the center of the body to accommodate internal support and adjustment components, preventing the structure from being exposed and affecting appearance and use. A base plate 21 is located within the groove 2, as shown in Figure 2. Multiple first support columns 3 are provided on the base plate 21. The first support columns 3 are injection molded from high-strength ABS engineering plastic, possessing good rigidity and fatigue resistance. A first support block 4 is provided at the upper end of each first support column 3. The first support block 4 is made of rigid EVA material with a Shore hardness of 60±5A, providing both elasticity and support, distributing body pressure, and preventing localized compression. Multiple rotating seats 5 are symmetrically arranged on the base plate 21. The rotating seats 5 are made of wear-resistant nylon material and have internal bearing grooves. A convex column 6 rotatably connects the rotating seats 5. The convex column 6 achieves the lifting and lowering adjustment of the moving plate 8 through a cam principle. As shown in Figure 3, a motor 7 is installed on the outer side of the rotating base 5. The motor 7 is a DC geared motor of model 37GB-555, with a rated voltage of 12V, a speed of 60rpm, and an output torque of 1.5N·m. It can precisely control the rotation angle of the convex column 6. Its output end is fixedly connected to the convex column 6 through a coupling, and the transmission efficiency is ≥95%. A movable plate 8 is provided on the upper end of the convex column 6. The movable plate 8 is slidably connected to the first support column 3 through a linear bearing. The linear bearing is fixedly installed on the movable plate 8 and slidably connected to the outer side of the first support column 3 to ensure smooth lifting without jamming. Multiple second support columns 9 are fixedly connected to the movable plate 8. The second support columns 9 are also made of ABS engineering plastic. A second support block 10 is provided on the upper end of the second support column 9. The second support block 10 is made of the same material as the first support block 4. As shown in Figure 2, the upper end of the first support block 4 is provided with a contact soft layer 12. The contact soft layer 12 can be fixed to the first support block by rivets or the like. The contact soft layer 12 includes a first padding layer 16 disposed above the first support block 4. The first padding layer 16 is made of EVA high-elastic foam, with a thickness of 20mm and a density of 25D. It has a rebound rate of more than 80% and can quickly respond to changes in human body pressure to provide basic elastic support. Above the first padding layer 16 is a second padding layer 17. The second padding layer 17 is an activated carbon coating, with a thickness of 10mm. It is filled with coconut shell activated carbon with a particle size of 2-3mm, which can absorb odors and moisture in the sleeping environment and keep the inside of the mattress dry. Above the second padding layer 17 is a third padding layer 18. The third padding layer 18 is made of slow rebound memory foam made of polyurethane foam, with a thickness of 30mm and a density of 50D. Its rebound time is 3-5 seconds. It can conform to the curve of human body temperature and pressure, disperse pressure on the lumbar spine, hips and other parts, and improve sleep comfort.The upper surface of the contact soft layer 12 is covered with an upper fabric layer 13; the upper fabric layer 13 is made of a bamboo fiber and cotton blend fabric, which is in direct contact with the human body and is soft and skin-friendly; the lower surface of the base plate 21 is covered with a lower fabric layer 14, which is made of wear-resistant Oxford cloth, waterproof and stain-resistant, protecting the base plate from ground wear; a side fabric layer 15 connects the edge of the lower fabric layer 14 and the edge of the upper fabric layer 13, and the side fabric layer 15 is made of elastic spandex fabric, which can adapt to the deformation of the mattress edge, while wrapping the internal structure to prevent dust from entering. Figure 4 As shown, when the movable plate 8 is raised to its highest position, the second support block 10 is 10-20mm higher than the first support block 4; when the movable plate 8 is lowered to its lowest position, the surface height of the second support block 10 is the same as that of the first support block 4, which is used as a conventional mattress. The first support block 4 and the second support block 10 have the same shape, both including a hemispherical body 19, and a flat support part 20 is provided above the hemispherical body 19; the arc-shaped structure of the hemispherical body 19 can distribute pressure, and the flat support part 20 ensures uniform contact with the mattress layer. Further, a limiting ring is provided on the first support column 3 located on the lower side of the movable plate 8. The limiting ring can be fixed to the first support column 3 by means of threads or interference fit, etc. The limiting ring is used to limit the downward movement range of the movable plate 8 to avoid excessive movement of the movable plate 8 causing the bed surface to collapse. During installation and debugging, the lower limit of the movable plate 8 can also be adjusted by adjusting the position of the limiting ring, thereby adjusting the flatness of the bed surface.

[0016] Working principle: The base plate 21 in the groove 2 in the middle of the mattress body 1 provides the installation base. During normal use, the movable plate 8 is in the lowest position, and the second support block 10 is level with the first support block 4. When massage is needed, the motor 7 drives the convex column 6 between the rotating seats 5 to rotate. The protruding part of the convex column 6 pushes the movable plate 8 to slide upward along the first support column 3, so that the second support column 9 drives the second support block 10 to rise above the first support block 4, lifting the corresponding area of ​​the contact soft layer 12, allowing the second support block 10 to rise and conform to the back, waist and buttocks of the human body. The motor can rotate the convex column 6 to a certain angle and then stop, so that the movable plate 8 drives the second support column 9 and the second support block 10 to rise. The height of the contact soft layer 12 at the first support block 4 is lower than the height of the contact soft layer 12 at the second support block 10, so that the mattress surface forms an alternating concave and convex surface. This structure can enhance the air circulation of the back, reduce the accumulation of sweat and improve sleep comfort. The reciprocating motion of the motor can also make the second support block 10 rise and fall back and forth to achieve the massage effect. The upward range of the moving plate 8 can be controlled by adjusting the rotation angle of the protruding column 6, thereby adjusting the lifting height of the second support block 10 to adapt to different massage needs and realize flexible switching between support and massage functions.
