Description

Technical Field

[0001] This utility model belongs to the field of sleep equipment technology, and in particular relates to an intelligent mattress system. Background Technology

[0002] As people's demands for sleep quality increase, smart mattress technology continues to develop. Traditional mattresses mostly use metal springs as their support structure, which cannot achieve intelligent adjustment of firmness and height, or personalized support, making it difficult to conform to the body curves and sleeping habits of different users. For example, people who habitually sleep on their side need more space for their shoulders and hips to sink in, while those who sleep on their backs need better lumbar support. Traditional mattresses struggle to meet these diverse needs simultaneously.

[0003] Airbag mattresses suffer from poor stability. When turning over or changing sleeping positions, the air flow within the airbags causes instability on the mattress surface, leading to wobbling and potentially disrupting sleep. Furthermore, the lack of precise body support makes it difficult for users to enter a deep sleep state. While the airbag inflation adjustment theoretically allows for personalized firmness, precise control is difficult in practice. Over-inflation results in a too-firm mattress, while under-inflation leads to a lack of support, negatively impacting the sleep experience. Additionally, when the airbags are low in air, friction noise from the airbag walls during turning contributes to a poor user experience. Moreover, with empty airbags, increasing inflation slows down the adjustment process and reduces the efficiency of coordinated work between the airbags. Therefore, existing traditional mattresses and airbag mattresses still have shortcomings in terms of support, quietness, comfort, and smart features, indicating significant room for improvement in the structure of smart mattresses.

[0043] The core of this invention is to provide an intelligent mattress system that utilizes airtight foam springs to achieve independent soft and firm support adjustment and coordinated operation in different parts of the mattress, enabling complex movements. Its structure is simple, it can achieve more precise control, and it is also quieter, more intelligent and user-friendly, providing users with a more comfortable sleep experience.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] An example of an implementation of the intelligent mattress system provided by this utility model Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a side view of an embodiment of the intelligent mattress system provided by this utility model. Figure 2 This is a top view of the arrangement of airtight foam spring units in an embodiment of an intelligent mattress system provided by this utility model. Figure 3 This utility model provides a schematic diagram of the control connection of an embodiment of an intelligent mattress system when divided into two groups of airtight foam springs. The intelligent mattress system may include:

[0046] The mattress main support component 1 includes multiple airtight foam spring units arranged in a matrix, wherein... Figure 1 The demonstration shows that this airtight foam spring unit can be used in six rectangular areas (shoulder S1, back S2, waist S3, hips S4, thighs S5, and calves S6), and... Figure 1The other two parts shown (head S0 and feet S7) can use support foam in some cases and airtight foam spring units in others, depending on the actual needs. Each airtight foam spring unit has an independent gas-storing chamber, meaning that each unit can be independently inflated or deflated without affecting other units. These matrix-arranged airtight foam spring units can be arranged along... Figure 2 The mattresses are arranged along the horizontal Y-axis, allowing for two columns to be set up along this direction. This enables separate adjustments for different body parts of two people lying on the bed. The "horizontal Y-axis" refers to the direction from the headboard to the footboard when the user is lying on the bed. Taking a common mattress 2 meters long and 1.8 meters wide as an example, the "horizontal Y-axis" here refers to this 2-meter length. This allows for independent adjustments to parameters such as firmness and height for different parts of the body lying on the mattress, resulting in higher levels of intelligence and collaborative control. It also provides users with various massage modes. Furthermore, the normal operating air pressure range of each airtight foam spring unit is -5kPa to 8kPa. It should be noted that 8kPa here refers to the pressure range without external... Under gravity, when pressed by external gravity, the upper limit of the air pressure value is 14 kPa. If the control system detects that the air pressure value reaches this upper limit, it will open the relevant valve to release the air. Moreover, 8 kPa is the hardest state, -3 kPa is the softest state, and -5 kPa is the lowest state of the airtight sponge spring. The height variation range can be 2 cm to 13 cm. A top interactive layer 101 can be laid on top of these airtight sponge spring units, which can be a breathable and comfortable pad to provide users with a comfortable lying feeling. Below these airtight sponge spring units can be a bottom support layer 102, which can be a rigid box frame. Its internal space can hold various required equipment, and the bottom support layer 102 can also have a bottom pad 103 at the bottom.

[0047] The air pressure regulating assembly 2 includes an airtight sponge spring inflation valve 21, an airtight sponge spring de-inflation valve 22, and an air pressure sensor 23, all of which are connected to the air passages of the aforementioned airtight sponge spring units; an inflation pump 24 connected to the other end of the airtight sponge spring inflation valve 21; a de-inflation pump 25 connected to the other end of the airtight sponge spring de-inflation valve 22; and an air pressure controller 26 electrically connected to the airtight sponge spring inflation valve 21, the airtight sponge spring de-inflation valve 22, the air pressure sensor 23, the inflation pump 24, and the de-inflation pump 25. It should be noted that... It is clear that, in this configuration, the air passage of each airtight sponge spring unit can be selectively connected, thus allowing individual control of parameters such as its pressure and stiffness. The aforementioned air pressure sensor 23 is used to monitor and assist in adjusting the air pressure value of each airtight sponge spring unit. It is electrically connected to the air pressure controller 26 mounted on the circuit board to provide the air pressure controller 26 with the current air pressure value within each airtight sponge spring unit. Thus, the air pressure controller 26 can determine whether to continue inflating or deflating based on this real-time air pressure value to ensure that a target air pressure value is reached. Figure 3 The demonstration shows the case where all the airtight sponge spring units are divided into two groups. The air pressure of the airtight sponge spring units in each group is adjusted synchronously. Of course, all the airtight sponge spring units can be divided into any number of groups according to actual needs, such as three groups, four groups, or even six groups. Each group must be equipped with a corresponding air pressure sensor and have a corresponding pipe connected to the airtight sponge spring exhaust valve 22 and airtight sponge spring inflation valve 21 to achieve air pressure adjustment for each group.

[0048] It should also be noted that the aforementioned air pressure regulating component 2 is also connected to a power supply component, a temperature monitoring component, etc. These components can all be installed on the same circuit board of the control host, and the user can use an infrared remote control to realize the command interaction between the user and the smart mattress system. In the default state, the air pressure value of the airtight foam spring unit in each group is consistent. When the user sets the softness, firmness and wrapping feel of each group through the infrared remote control, this air pressure regulating component 2 can perform the corresponding inflation and deflation operations to meet the user's needs. Of course, other methods can also be used for user interaction to obtain the user's relevant control commands, such as voice, mini-programs and APPs, etc., which are not limited here.

[0049] As described above, in the embodiments of the intelligent mattress system provided by this utility model, the main support component of the mattress includes multiple airtight foam spring units arranged in a matrix, each of which has an independent air-storing chamber. The air pressure regulating component includes an airtight foam spring inflation valve, an airtight foam spring de-inflation valve, and an air pressure sensor connected to the air passage of the airtight foam spring unit; an inflation pump connected to the other end of the airtight foam spring inflation valve; a de-inflation pump connected to the other end of the airtight foam spring de-inflation valve; and an air pressure controller electrically connected to the airtight foam spring inflation valve, airtight foam spring de-inflation valve, air pressure sensor, inflation pump, and de-inflation pump. Therefore, it is evident that air pressure can be utilized... The controller precisely controls the independent inflation chambers within each airtight foam spring unit. When a certain area needs to be softer, a certain amount of air can be extracted from the corresponding inflation chamber; conversely, when a certain area needs to be firmer, air can be injected into the corresponding inflation chamber. These processes can be achieved more quickly and intelligently. Moreover, these airtight foam spring units do not generate noise due to mutual friction. Therefore, this intelligent mattress system can utilize airtight foam springs to achieve independent adjustment of the firmness and softness of different parts of the mattress and to work collaboratively to achieve complex movements. Its simple structure allows for more precise control, lower noise, and greater intelligence and user-friendliness, providing users with a more comfortable sleep experience.

[0050] Furthermore, most existing electric bed frames use direct-drive motors to achieve a zero-gravity effect by raising the back and lower legs. These motors are prone to overheating during continuous operation, leading to a higher failure rate. They also suffer from drawbacks such as high noise levels, complex structures, and high costs. Therefore, based on this issue, we will continue to refer to… Figure 1 and Figure 3 This application also provides a specific embodiment of a smart mattress system, which, based on the above embodiments, may further include:

[0051] The back-lifting component 3 includes a back airbag 301, positioned in the area corresponding to the user's back when lying flat. Preferably, it is a corrugated airbag. It may also include a first rigid box-type connecting shaft 302. When the back airbag 301 is inflated, it lifts the corresponding area of ​​the user's lower back upwards. The rotation of the first rigid box-type connecting shaft 302 causes the rigid box structure to rotate accordingly, reaching a desired angle to meet the user's needs in various postures. After the back is lifted... Figure 4 As shown, Figure 4 This is a schematic diagram of the smart mattress system after the back is lifted.

[0052] The calf lifting component 4 includes a calf airbag 401, which is positioned in the area corresponding to the user's calf when lying flat. A corrugated airbag can also be used. It can also be matched with a second rigid box structure connecting shaft 402 and a third rigid box structure connecting shaft 403. When the calf airbag 401 is inflated, it lifts the corresponding part of the user's calf upward. The rotation of the second rigid box structure connecting shaft 402 and the third rigid box structure connecting shaft 403 can cause the rigid box structure to rotate accordingly, so that the rotation reaches a certain required angle, changing the shape of the mattress, which can reduce leg pressure, promote blood circulation, and improve the user's comfort when lying down.

[0053] Continue to refer to Figure 3 The back airbag 301 and the calf airbag 401 are both connected to the airbag inflation valve 27 and the airbag deflation valve 28. The airbag inflation valve 27 is connected to the inflation pump 24, and the airbag deflation valve 28 is connected to the deflation pump 25. The air pressure controller 26 is also electrically connected to the airbag inflation valve 27 and the airbag deflation valve 28. In this case, after receiving relevant control commands from the user, the air pressure controller 26 can control the airbag inflation valve 27 and the inflation pump 24 to open, so as to inflate the back airbag 301 and the calf airbag 401, thereby increasing the height of these two parts. The mattress is raised so that both sides are at a certain angle to the horizontal. Then, the airbag inflation valve 27 is closed and the air pump 24 is stopped, allowing users to experience various postures. When the user cancels the control command corresponding to the posture requirement, the airbag de-gas valve 28 and the de-gas pump 25 are activated to release the air from the back airbag 301 and the lower leg airbag 401, thereby lowering the height of the corresponding parts and finally restoring the mattress to its initial flat state. At this time, the airbag de-gas valve 28 is closed and the air pump 25 is stopped.

[0054] Furthermore, both the back airbag 301 and the calf airbag 401 can preferably be corrugated airbags with multiple layers of composite elastic material or multiple layers of single elastic material. As a novel stretchable structure, it can deform significantly in the vertical direction, meaning it has axial stretching characteristics and a certain radial compressive strength, providing stable support performance. The composite elastic material refers to a composite of elastic material and other materials, such as TPU and fabric, or silicone and fabric. The corrugated airbag has 3 to 6 layers, more preferably 5 layers, with the layers connected by air pores. The height of each layer after inflation is 2 cm to 10 cm. Specifically, the height of the back airbag and calf airbag can be controlled from 0 to 50 cm, and the lifting angle from 0 to 60° to meet the needs of different usage scenarios such as reading, watching TV, zero gravity, breastfeeding, and assisting in getting up. The bottom airbag layer can be equipped with an air nozzle, connected to the air pressure controller 26 via tubing. In another implementation, the airbags can be stacked vertically without being connected to each other, with overlapping parts glued together. Each airbag is equipped with an air nozzle, connected to the air pressure controller 26 via tubing. During inflation, each layer unfolds sequentially for smooth lifting, and during deflation, each layer contracts sequentially to ensure stability. The cross-sectional shape of the aforementioned corrugated airbag can be U-shaped or T-shaped, such as... Figure 5 As shown, Figure 5 The diagram shows cross-sectional views of U-shaped and T-shaped corrugated airbags. The left side shows a U-shaped corrugated airbag, and the right side shows a T-shaped corrugated airbag. This design provides better stability, faster inflation, less damage, and easier maintenance. The U-shaped corrugated airbag reduces deformation stress and has a simple structure. Furthermore, the corrugated airbag is preferably equipped with breathable elastic sponge, which reduces the amount of air needed and speeds up inflation, allowing the desired angle to be reached more quickly and providing a better user experience.

[0055] Continue to refer to Figure 1 and Figure 3 Furthermore, the aforementioned back-lifting component 3 may also include a back height sensor 303, located in the area corresponding to the back airbag 301; and a calf height sensor 404, located in the area corresponding to the calf airbag 401; the air pressure controller 26 is also electrically connected to the back height sensor 303 and the calf height sensor 404. In this configuration, the air pressure controller 26 can obtain the real-time height of the back airbag and the calf airbag, and stop inflation when the corresponding height is reached. This allows for more precise height control, enabling more accurate execution of user commands, and also allows for setting certain thresholds to prevent over-inflation of the airbags and the associated safety risks.

[0056] It should also be noted that, in this embodiment, by combining the support structure formed by the airtight foam spring units with the back lifting component and the calf lifting component made of corrugated airbags, coordinated control of multi-area support and lifting of the mattress can be achieved. Multiple inflation valves and deflation valves (selectably a solenoid valve group) are used, with the solenoid valve group controlling the inflation and deflation of each airtight foam spring unit and lifting component, thereby achieving integrated intelligent control. Furthermore, the aforementioned airbag inflation valve 27 can preferably be a pressure-holding solenoid valve, and the aforementioned airbag deflation valve 28 can preferably be a two-way solenoid valve. Additionally, each airtight foam spring unit can be equipped with a corresponding air pressure sensor to monitor and transmit its air pressure. The air pressure regulating component 2 utilizes this feedback mechanism to make the air pressure regulation of each airtight sponge spring unit more precise, and provides a basis for the coordination between the airtight sponge spring unit and the back lifting component and the calf lifting component. After all, when the back or calf is lifted, it will compress the adjacent airtight sponge spring units. When the air pressure sensor in these airtight sponge spring units detects that the air pressure is too high, it can feed back to the air pressure regulating component 2. The air pressure regulating component 2 can then control the corresponding airtight sponge spring suction valve 22 to open and turn on the suction pump 25, so that the air pressure of the airtight sponge spring unit in that part is reduced to a suitable value to avoid the risk of excessive air pressure. In a specific example, upon receiving a user's instruction, the air pressure controller 26 controls the air pump to inflate the back airbag 301 to achieve a smooth back lift. The back height sensor 303 provides real-time feedback on the back lift height. As the back lifts, the airtight foam spring units S2 and S3 compress each other, increasing their internal air pressure by 0.5 kPa. The air pressure controller 26 then controls the deflation of these two units to maintain their set air pressure value and ensure safety. When the lower legs lift, the airtight foam spring unit S6 is compressed by the upper comfort layer and mattress cover, increasing its internal air pressure by 0.5 kPa. The air pressure controller 26 then controls its deflation to maintain its set air pressure value and similarly ensure safety.

[0057] When the back and calves need to return to their original horizontal position, the control system activates the corrugated airbag 105 or 109 to deflate to zero pressure, and at the same time activates the vacuum pump to evacuate air, so that the corrugated airbag 105 or 109 is in a vacuum state, and the height of the corrugated airbag 105 or 109 is reduced to less than 8cm.

[0058] In another specific embodiment of the aforementioned smart mattress system, refer to... Figure 3The main support component 1 of the mattress includes six airtight foam spring units S1, S2, S3, S4, S5 and S6, and all the airtight foam spring units are divided into two groups. The airtight foam springs of the shoulder S1, back S2, thigh S5 and calf S6 are in the first group, and the airtight foam springs of the waist S3 and hip S4 are in the second group.

[0059] The airtight sponge spring inflation valve 21 is preferably a double pressure-holding solenoid valve, which is used to connect to the air circuits of two sets of airtight sponge spring units respectively. This allows for independent group control according to the sleeping area. The airtight sponge spring units in each group can be synchronously inflated or deflated, without affecting each other with the airtight sponge spring units in the other group. Specifically, the double pressure-holding solenoid valve can be a two-position three-way solenoid valve. Of course, other types of solenoid valves can also be selected according to actual needs, such as two-position four-way solenoid valves, etc. There is no limitation here.

[0060] The airtight sponge extraction valve 22 is preferably a two-way solenoid valve, used to connect to the air passages of the two sets of airtight sponge spring units respectively.

[0061] It should be noted that the structure of the airtight sponge spring unit used in this solution can be as follows: Figure 6 , Figure 7 and Figure 8 As shown, Figure 6 This is a schematic diagram of the cross-section of an airtight sponge spring unit. Figure 6 As can be seen, the airtight sponge spring unit 5 can be an elastic bladder with a sealing effect formed by bonding a layer of elastomer 502 to the outer peripheral surface of the breathable elastic sponge 501. It is preferable to use a breathable elastic sponge with an open porosity of 70%, so that the inflation efficiency can be increased by two-thirds compared with an air bladder of the same volume. In addition, there is an air nozzle 503 that penetrates the elastomer 502 and the breathable elastic sponge 501 to provide a channel for inflation and deflation, so that its softness and hardness characteristics can be adjusted by controlling the inflation and deflation. Figure 7 This is a schematic diagram of the first possible appearance of an airtight foam spring unit. In its zero-pressure state, it is a cuboid. When inflated to a pressure exceeding kilopascals, the four larger surfaces deform slightly, with each surface bulging slightly from the center, but still maintaining its basic shape. When deflated, its surface exhibits an irregular, uneven appearance, and the overall shape resembles a cuboid. Figure 8 This is a schematic diagram of the second appearance of the airtight sponge spring unit, which presents the following characteristics when in a zero-pressure state: Figure 8 As shown, during inflation, radial deformation is small; during deflation, the entire structure contracts vertically, like a metal spring. In summary... Figure 7 and Figure 8The structures shown can all be used as support layers to achieve soft and hard adjustment and coordinated operation. Of course, in addition to these two geometries, other shapes of airtight sponge spring units can also be selected, such as relief shapes, etc., which are not limited here.

[0062] This grouping method provides a gentle, sleep-aiding massage function with two modes: strong and comfortable. The specific implementation is as follows: Based on the user-set pressure and softness level, the pressure difference between the first and second airtight sponge spring units is 5 kPa, which is the strong mode; when the pressure difference is 3 kPa, it is the comfortable mode. The two sets of airtight sponge spring units alternately inflate and deflate, creating variations in the support area. Furthermore, this embodiment can also provide individual adjustment of the lumbar pressure and massage function. Specifically, based on the user-set pressure and softness level, the user can independently increase the pressure of the second set of airtight sponge spring units (lumbar and hip group) by 2 kPa to enhance lumbar support and alleviate discomfort. The individual lumbar massage function automatically inflates and deflates the second set of airtight sponge spring units (lumbar and hip group) based on the user-set pressure and softness level, repeatedly changing the pressure and softness of the lumbar and hip group to achieve individual massage of the lumbar region. It should be noted that other grouping methods can also be used. For example, the airtight foam spring units in the waist and other positions can be connected into one group, while the airtight foam spring in the buttocks can be in a separate group; or the waist can be in a separate group, the buttocks can be in a separate group, and the remaining airtight foam spring units can be divided into a group, with the number of solenoid valves and air pressure sensors increased accordingly. These can all be selected according to actual needs.

[0063] In another specific embodiment of the above-mentioned smart mattress system, the main support component 1 of the mattress includes six airtight foam spring units S1, S2, S3, S4, S5 and S6, and each airtight foam spring unit is a group.

[0064] The airtight sponge spring inflation valve 21 is preferably a six-way pressure-holding solenoid valve, used to connect to the air passages of six sets of airtight sponge spring units respectively. This allows each airtight sponge spring unit to be inflated or deflated independently without mutual interference with other airtight sponge spring units. Furthermore, the airtight sponge spring deflator valve 22 is preferably a six-way double-port solenoid valve, used to connect to the air passages of six sets of airtight sponge spring units respectively. This embodiment is relative to... Figure 3Structurally, only some gas passages and valves have been modified; most parts remain the same, so they will not be described in detail here. Using this approach, each airtight sponge spring unit is connected to a solenoid valve array via a pressure-dividing gas path, forming a six-channel independent control scheme capable of ergonomic adaptation and precise zoned control. Additionally, it may include related power supply equipment, circuit boards, temperature control modules, etc., which will not be elaborated upon here. It is evident that this approach enables independent and precise control of the six airtight sponge spring units, while maintaining coordinated operation, allowing for intelligent regulation of certain special functions.

[0065] This six-unit airtight sponge spring system enables a variety of gentle wave massage modes for sleep aid. Specifically, the airtight sponge spring units S1, S3, S5 and S2, S4, S6 are alternately inflated and deflated. The units are inflated and deflated sequentially from head to toe and then from toe to head, creating dynamic undulations throughout the support area. The air pressure variation range of the airtight sponge spring units is between -3kPa and 5kPa, and the pressure difference between the units is between 3kPa and 6kPa, allowing for undulations of varying intensities.

[0066] Additionally, this configuration allows for individual adjustment of the lumbar support's firmness and provides individual lumbar massage. Users can individually increase the pressure of the airtight foam spring unit S3 (or S3 and S4 simultaneously) by 2 kPa. Other adjacent airtight foam spring units depress or deflate to reduce air pressure, enhancing lumbar support and alleviating discomfort. The individual lumbar massage function is implemented as follows: Inflation and depressing of the airtight foam spring unit S3 (or S3 and S4 simultaneously) are repeatedly performed to change the firmness of S3 (or S3 and S4). Other adjacent airtight foam spring units depress or deflate to reduce air pressure, thus providing individual lumbar massage. In this embodiment, airtight foam spring units S1 to S6 can be arbitrarily grouped. Through differentiated air pressure combinations, discrete airtight foam spring units are transformed into continuously programmable mechanical surfaces, enabling the smart mattress to perform complex multi-degree-of-freedom movements.

[0067] In a preferred embodiment of the aforementioned smart mattress system, the main mattress support component 1 may further include a head support airtight foam spring unit and / or a foot support airtight foam spring unit. The head support airtight foam spring unit is used to adjust the height of the head area of ​​the mattress, which also affects the user's posture. It may have a corrugated appearance on a vertical surface, with a corrugation depth of 4cm. When there is one corrugation, it is V-shaped; when there are two corrugations, it is W-shaped. It may also be a combination of two independent layers of airtight foam springs, or a combination of three-dimensional airbags and airtight foam springs. By inflating and deflating these springs to change their height and position, the sleeping posture can be adjusted, thus achieving an anti-snoring function. The foot support airtight foam spring unit is used to adjust the height of the foot area of ​​the mattress. In this case, these airtight foam spring units can be divided into two, three, six, or seven groups. It should be noted that... (The text abruptly ends here, likely due to an incomplete translation or source material.) Figure 1 ,that is Figure 1 In this example, airtight foam spring units are used for both S0 and S7. In a specific example, the dimensions of the airtight foam spring units in sections S1 to S7 can be: 74cm long, 16cm wide, and 12cm high. Depending on the application, the length can vary from 60cm to 80cm, the width from 12cm to 30cm, and the height from 5cm to 12cm. In the same application scenario, when there is no force applied, S1 to S7 have a flat appearance and uniform height when their internal air pressure is zero. S0 is 5cm higher than S1 to S7 in a zero-pressure state. To maintain the same height as S1 to S7, it needs to be depressurized to a negative pressure of 3kPa. This is the normal air pressure value of S0. To change the head height, S0 needs to be restored to its zero-pressure height and inflated to 1kPa to 2kPa. Under normal circumstances, the air pressure of S1 to S7 varies from -5kPa to 6kPa when there is no force applied. This is the basic air pressure range; different air pressure values ​​result in different levels of firmness. It should also be noted that this head-supporting airtight sponge spring unit can be a corrugated columnar airbag or a single columnar airbag connected in series with the airtight sponge spring unit. In this case, its internal air pressure is normally zero. When the head height needs to be adjusted, inflating or depressing the internal airbag changes its position, thus affecting the user's sleeping posture and achieving an anti-snoring function.

[0068] Based on the various embodiments of the above-mentioned smart mattress system, it may include a bottom support layer, a middle functional layer and a top interactive layer from bottom to top;

[0069] The bottom support layer is a rigid box-type frame, which can be made of ABS or metal composite materials, with a load-bearing capacity of not less than 300 kg. The air pressure regulating component is located in the bottom support layer. Additionally, if a backrest lifting component and a calf lifting component are included, these components are also placed inside this rigid box-type frame. These lifting components are preferably U-shaped corrugated airbags with a pressure resistance of ≥20 kPa, but can be adapted to meet specific needs; there are no limitations here. Furthermore, if a backrest height sensor and a calf height sensor are included... In this case, the back height sensor and calf height sensor can also be placed inside this rigid box frame. Furthermore, expansion slots for connecting to hardware that enhances sleep comfort can also be placed within this rigid box frame. In a specific example of a rigid box frame, it is rectangular in shape, 10cm high, with the same length and width as a standard mattress. The frame is constructed of metal and includes four sections: head, back, and waist (70cm long); hips (40cm long); thighs (40cm long); and calves and feet (50cm long). These four sections are connected using hinges. A thin plate can be fixedly installed on the upper part of this rigid box frame to support the main support structure of the smart mattress (airtight foam spring units and / or foam layers). A bottom pad 103 can be installed on the lower part of this rigid box frame to fix the hip area to the rigid box frame. The head, back, and calf areas mainly house the back lifting component 3 and the calf lifting component 4, while the hip and thigh areas mainly house the air pressure adjustment component 2 and other functional modules.

[0070] The aforementioned airtight sponge spring unit is located in this central functional layer, and the airtight sponge spring unit is cylindrical or prismatic in shape, serving as a basic support and a softness / hardness adjustment function.

[0071] The top interactive layer is a removable fabric face mask and a breathable comfort layer, the main function of which is to provide users with soft comfort.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
