Description

Technical Field

[0001] The present invention belongs to the technical field of smart mattresses, and in particular relates to a body position sensing mattress with an early warning function based on health sign monitoring. Background Art

[0002] Mattress is an indispensable living appliance in people's daily life, which can greatly enhance people's sleeping comfort.

[0003] Mattresses are essential household items, and their quality and comfort directly impact comfort. With the continuous advancement of material civilization and technological advancements, the types of mattresses used by modern people have become increasingly diverse, including spring mattresses, palm mattresses, latex mattresses, water mattresses, and magnetic mattresses. Among these mattresses, spring mattresses account for a larger proportion.

[0004] Therefore, choosing the best mattress should start with its function. A mattress's function is to ensure a healthy and comfortable sleep. A good mattress has two key criteria: first, it ensures the spine remains straight and stretched regardless of sleeping position; second, it provides even pressure, allowing the entire body to fully relax. This factor influences the mattress's firmness.

[0005] The firmness of a mattress depends on the firmness of its inner springs. In addition to the necessary firmness for support, springs should also have good resilience—a balance of firmness and flexibility. If the springs are too firm or too soft, the rebound is unsatisfactory. A mattress that is too firm only places pressure on the head, back, buttocks, and heels, while the rest of the body isn't fully supported. This puts the spine in a state of stiffness and tension, preventing optimal rest and potentially damaging health over time. A mattress that is too soft causes the entire body to sag, keeping the spine bent for extended periods and compressing internal organs. This, over time, is also detrimental to health and discomfort. Therefore, a mattress with the right balance of firmness and firmness should be chosen.

[0006] Therefore, the existing mattress structure is generally based on an independent spring cavity to improve elasticity. However, the spring structure is prone to elastic fatigue after long-term use, the reset effect is low, and the two ends of the spring are easy to penetrate the mattress surface, which has low safety. At the same time, in the existing smart mattress, it is generally based on the addition of multiple sensors, and there is no structure for early warning. Summary of the Invention

[0024] The panel 1 includes a cotton cloth surface layer 4, a cotton yarn layer 5, and an elastic film layer 6. The cotton cloth surface layer 4, the cotton yarn layer 5, and the elastic film layer 6 are bonded and fixed in sequence.

[0025] Specifically, the cotton cloth surface layer 4 is made of pure cotton fiber woven material, providing comfortable contact with the body skin. The cotton yarn layer 5 is made of twisted cotton yarn woven material and its gap is larger than the cotton cloth surface layer 4. The elastic film layer 6 is made of silicone PDMS film material, which has high strength and strong adhesion. The panel 1 composed of the cotton cloth surface layer 4, the cotton yarn layer 5, and the elastic film layer 6 has good breathable and comfortable performance, and the elastic film layer 6 is used as a support at the bottom to facilitate fixation with the set filling unit.

[0026] At the same time, a protective cotton cloth side panel 7 is arranged between the two panels 1. The protective cotton cloth side panel 7 is sewn and fixed to the cotton cloth surface layer 4 on the panel 1. A breathable cotton layer 8 is bonded to the inner side of the protective cotton cloth layer. The protective cotton cloth layer and the cotton cloth surface layer 4 are made of the same material. The breathable cotton layer 8 is arranged inside the protective cotton cloth layer to improve the overall breathability of the mattress and avoid the accumulation of internal odor.

[0027] A silicone mesh plate 2 is set between the two panels 1 for filling, and is filled between all the filling silicone blocks 3 to improve the support performance of the mattress. The upper and lower ends of the silicone mesh plate 2 are bonded and fixed to the elastic film layer 6, and the two sides of the silicone mesh plate 2 are in contact with the side surfaces of the filling silicone block 3. Honeycomb holes 9 are provided inside the silicone mesh plate 2, and the honeycomb holes 9 are evenly distributed inside the silicone mesh plate 2. At the same time, a large number of honeycomb holes 9 are provided inside the silicone mesh plate 2. While reducing the overall weight of the mattress, due to the presence of the honeycomb holes 9, its overall elastic performance is increased, which can further improve the comfort of using the mattress.

[0028] Specifically, in this embodiment, the body position sensing warning unit includes a groove 10 fixed on the surface of the filled silicone block 3, the groove 10 is set toward the panel 1 side, and a pressure sensor module 11 is embedded in the groove 10. The surface of the pressure sensor module 11 is higher than the surface of the groove 10. It also includes a vibrator bonded to the elastic film layer 6, and the vibrator is set near the edge of the panel 1. There are several vibrators equidistantly set along the edge of the panel 1, and the vibrators are located below the cotton yarn layer 5 and the cotton cloth layer.

[0029] The pressure sensor modules 11 are independently controlled, and each pressure sensor module 11 is connected to an amplification module, the electrical signal of the amplification module is connected to the analog-to-digital conversion module, the electrical signal of the analog-to-digital conversion module is connected to the processing module, the electrical signal of the processing module is connected to the display screen, and the display screen has a built-in digital image conversion module. The pressure sensor modules 11 near the edge of the panel 1 are connected in series, and after the series connection, they are connected to the PLC control module, and the electrical signal of the PLC control module is connected to the vibrator.

[0030] The pressure sensor module 11 close to each side panel 1 is independently powered. In this embodiment, a control button switch can be used and set on one side of the mattress to independently control the pressure sensor module 11 of each panel 1, so that the two side panels 1 of the mattress have the same function and can be used on both sides.

[0031] The pressure sensor module 11 can monitor the pressure changes on its surface in real time. The pressure sensor modules 11 near the edge of the panel 1 are all provided with thresholds. When the surface pressure of the pressure sensor module 11 changes, the internal voltage changes and generates an electrical signal. The signal of the voltage change is amplified by the amplification module, and the amplified analog signal is converted into a digital signal based on the analog-to-digital conversion module. After the electrical signal is processed by the processing module, it is uploaded to the display screen. At the same time, after data processing by the digital image conversion module inside the display screen, an image of the pressure distribution change is displayed on the display screen. The control structures of each module can be integrated with the display screen and used as an overall controller.

[0032] At the same time, when the surface pressure value of the pressure sensor module 11 at the edge of the panel 1 exceeds a preset threshold, the voltage change generates an electrical signal, and the vibrator is controlled by the PLC control module. After the vibrator is working, it can prompt the user, and then realize edge warning, so as to notify the sleeping person of the risk of falling; in this embodiment, an alarm can be used instead of the vibrator, for children or the elderly, to notify the accompanying people to avoid falling.

[0033] The vibrator is a micro motor and eccentric wheel structure.

[0034] Specifically, the vital sign monitoring unit includes a fixed box 21 pasted on the elastic film layer 6, a cotton yarn layer 5 extends from the top of the fixed box 21, and the cotton cloth layer covers the top of the fixed box 21. A metal plate 22 is fixed on the top of the fixed box 21, and a PPG sensor module 23 is embedded in the metal plate 22. The fixed boxes 21 are evenly distributed on the elastic film layer 6, and the electrical signals of all PPG sensor modules 23 are connected to the processing module.

[0035] At the same time, a metal plate 22 and a PPG sensor module 23 are provided below the panel 1, which can come into contact with the sleeping body and monitor physical signs through the PPG sensor module 23. At the same time, multiple PPG sensor modules 23 are provided to monitor different parts of the body and obtain relevant pulse changes. At the same time, the information is uploaded to the display screen for display and observation.

[0036] A fixing seat 12 is fixed to the end of the filling silicone block 3 away from the pressure sensor module 11. The fixing seat 12 is screwed inside the silicone block. The fixing seats 12 are symmetrically distributed and are provided with four. A first connecting rod 13 is rotatably connected between two fixing seats 12 arranged upper and lower, and a second connecting rod 14 is rotatably connected between the two fixing seats 12 opposite to the first connecting rod 13. The first connecting rod 13 and the second connecting rod 14 are cross-arranged. A through groove 15 is provided inside the first connecting rod 13, and the second connecting rod 14 is rotatably passed inside the through groove 15. A TPU top support bar 16 is rotatably connected between the other two fixing seats 12 arranged upper and lower.

[0037] A through hole is provided on the side of the first connecting rod 13, and a double-headed threaded pin 17 is inserted into the through hole. Locking nuts are threadedly connected at both ends of the double-headed threaded pin 17. A damping rod 24 is rotatably connected to the outside of the double-headed threaded pin 17. The damping rod 24 is rotatably connected to the side of the second connecting rod 14 away from the end of the double-headed threaded pin 17. An ear plate 18 is fixed to the side of the second connecting rod 14, and the damping rod is rotatably connected to the inside of the ear plate 18.

[0038] After applying pressure on the panel 1, the panel 1 drives the filling silicone block 3 at the pressure position to move downward, and then the first connecting rod 13 and the second connecting rod 14 rotate at the same time. During the rotation, the damping rods on both sides begin to shrink, and the filling silicone block 3 is used to replace the spring rebound structure in the existing mattress. This structure has stable support and is reset by the damping rod, and the reset time is short. At the same time, the side of the filling silicone block 3 is filled with the silicone mesh plate 2, which has stable support and low deformation, and can be used for a long time. At the same time, the internal first connecting rod 13 and the second connecting rod 14 rotate inside the fixing seat 12, and can be disassembled and assembled by screws. The damping rod is hinged at one end and installed at the other end by a double-headed threaded pin 17, which is convenient for subsequent maintenance.

[0039] A non-woven fabric layer 19 is further bonded between the two filled silicone blocks 3 , and a nano rubber sound insulation board 20 is attached to the inner wall of the non-woven fabric layer 19 . The non-woven fabric layer 19 completely covers the outside of the first connecting rod 13 and the second connecting rod 14 .

[0040] The non-woven fabric layer 19 and the nano-rubber sound insulation board 20 arranged on the inner wall can be extended and retracted in the upper and lower positions without affecting the movement of the filling silicone block 3. The nano-rubber sound insulation board 20 has a good sound insulation effect and can isolate the sound generated during the rotation of the internal first connecting rod 13 and the second connecting rod 14, effectively improving the overall quiet effect of the mattress and further improving sleeping comfort.

[0041] The working principle of the present invention is as follows: after the mattress is used, the display screen is installed and fixed at the head of the bed or other locations, and the pressure sensor module 11 in the contact panel 1 is turned on. Through the internal PPG sensor module 23, different parts can be monitored to obtain relevant pulsation changes, and the information is uploaded to the display screen for display and observation; and the movement trajectory during sleep can display the pressure distribution change image on the display screen; when the surface pressure value of the pressure sensor module 11 at the edge of the panel 1 exceeds the preset threshold, the voltage change generates an electrical signal, and the vibrator is controlled by the PLC control module. After the vibrator is working, it can prompt the user, and then realize edge warning, so as to notify the sleeping person of the risk of falling.

[0042] In particular, the electronic components in this embodiment are all powered by an indoor power supply. In combination with the installation of the display screen, the display screen and the above-mentioned controller are connected to a 220V power grid.
