[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] As people pay more attention to sleep quality, their requirements for mattresses have also increased. In particular, they expect mattresses to provide accurate and comfortable support based on the physiological characteristics of different parts of the human body and different sleeping positions. Traditional mattresses often use fixed materials and structures, which makes it difficult to achieve personalized fit support and cannot meet people's diverse needs.

[0035] In addition, in scenarios such as RVs and temporary living spaces where the form needs to be changed frequently, mattresses with folding functions are more practical. However, in related technologies, smart mattresses often cannot take into account both adaptive adjustment and folding functions in terms of airbag partitioning.

[0036] The embodiment of the present invention provides a method for adjusting a smart mattress, wherein the smart mattress includes a plurality of airbags, and the support force of the smart mattress can be adjusted by inflating / deflating the airbags to make it fit the human body better. By obtaining the distribution of the airbags, and based on the distribution, the smart mattress is divided into a plurality of areas, the user's coverage range is determined by collecting the pressure signals of each airbag in the area, and the first pressure in the coverage range is obtained. By comparing the first pressure with the preset range, the area to be adjusted is determined, and the amount of gas in the airbag in the area to be adjusted is adjusted until the pressure of the airbag is within the preset range. The above scheme divides the smart mattress according to the distribution of the airbags, and adjusts the smart mattress in different areas according to the divided target areas. Compared with the overall adjustment of the smart mattress, it can be more targeted and improve the user experience. By adjusting the amount of gas in the airbag in the area to be adjusted according to the preset range, the smart mattress can be adjusted according to user needs, thereby improving the adaptability of the method.

[0037] According to an embodiment of the present invention, an embodiment of an intelligent mattress adjustment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] In this embodiment, a smart mattress adjustment method is provided, which is applied to a control module in a smart mattress, wherein the smart mattress also includes a plurality of air bags. Figure 1 is a flow chart of a smart mattress adjustment method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0039] Step S101, obtaining the distribution of airbags.

[0040] The smart mattress includes several air bags, and their distribution and the amount of gas in the air bags will directly affect the support and comfort of the smart mattress. By adjusting the air bags in the smart mattress through the control module in the smart mattress, the mattress can be made to fit the body curve better, thereby improving the user experience.

[0041] The distribution of airbags in the smart mattress can be directly obtained through the design document of the smart mattress. The distribution of airbags can include the position, size, arrangement of each airbag, and distribution density in each area.

[0042] Step S102: based on the distribution, the smart mattress is divided into several target areas, and the pressure signals of the airbags in the target areas are collected.

[0043] After obtaining the distribution of the airbags inside the smart mattress, the smart mattress can be divided into several target areas according to the body parts. The target areas may include the head, neck, shoulders, back, waist, buttocks, legs, etc. By dividing the smart mattress according to different parts of the human body, the corresponding airbags can be adjusted according to the support requirements of different parts for the airbags.

[0044] In some optional implementations, the airbags may be divided into support strengthening areas, comfort adjustment areas, etc. according to the distribution of the airbags and their functions. By dividing the smart mattress according to the functions of the airbags, the airbags in the corresponding areas may be adjusted according to the user's requirements for the support strength and comfort of the mattress.

[0045] Based on the distribution of airbags, the smart mattress is divided into several target areas, and the pressure signals of the airbags in each target area can be collected through pressure sensors. The pressure sensors can be installed inside the airbags or in direct contact with the airbags to ensure that the pressure inside the airbags can be accurately measured, so as to accurately adjust the smart mattress.

[0046] Step S103: determine the coverage range of the user based on the pressure signal, and obtain a first pressure within the coverage range.

[0047] When the user lies on the mattress, the airbag pressure in different areas will change to different degrees. Therefore, a coverage threshold can be set to determine the coverage range of the user in the target area by comparing the airbag pressure with the coverage threshold. After determining the coverage range of the user, the first pressure can be determined by calculating the quotient of the pressure signal and the coverage range.

[0048] Step S104, comparing the first pressure with a preset range, and determining the area to be adjusted based on the comparison result.

[0049] By comparing the first pressure with the preset range, it can be determined whether the support force provided by the airbag in this area meets the preset support force. When the first pressure is not within the preset range, it means that the support force provided by the airbag corresponding to the first pressure cannot meet the user's needs and needs to be adjusted. The target area corresponding to the airbag can be marked as the area to be adjusted to facilitate subsequent unified adjustment and improve the convenience of the method.

[0050] Step S105, adjusting the gas volume of the airbag in the area to be adjusted until the pressure of the airbag in the area to be adjusted meets a preset range.

[0051] Among them, the airbag can be inflated or deflated according to the relationship between the first pressure and the preset range.

[0052] Specifically, when the first pressure is less than the lower limit of the preset range, it means that the supporting force provided by the corresponding airbag is less than the supporting force required by the user, and the airbag can be inflated to increase the supporting force.

[0053] When the first pressure is greater than the upper limit of the preset range, it means that the supporting force provided by the corresponding airbag is greater than the supporting force required by the user. The airbag can be deflated to reduce the supporting force provided by the airbag to improve the user experience.

[0054] When adjusting the amount of gas in the airbag in the area to be adjusted, the pressure signal can be continuously collected and the first pressure can be updated. The amount of gas in the airbag can be adjusted based on the relationship between the updated first pressure and the preset range to prevent overshoot or insufficient adjustment from causing a decrease in user experience.

[0055] The smart mattress adjustment method provided in this embodiment includes a plurality of airbags, and the support force of the smart mattress can be adjusted by inflating / deflating the air to make it fit the human body better. By obtaining the distribution of the airbags, and based on the distribution, the smart mattress is divided into several areas, the user's coverage range is determined by collecting the pressure signals of each airbag in the area, and the first pressure in the coverage range is obtained. By comparing the first pressure with the preset range, the area to be adjusted is determined, and the amount of gas in the airbag in the area to be adjusted is adjusted until the pressure of the airbag is within the preset range. The above scheme divides the smart mattress according to the distribution of the airbags, and adjusts the smart mattress in different areas according to the divided target areas. Compared with the overall adjustment of the smart mattress, it can be more targeted and improve the user experience. By adjusting the amount of airbag gas in the area to be adjusted according to the preset range, the smart mattress can be adjusted according to user needs, thereby improving the adaptability of the method.

[0056] In this embodiment, a smart mattress adjustment method is provided. The method is applied to a control module in a smart mattress. The smart mattress also includes a plurality of air bags. Figure 2 is a flow chart of a smart mattress adjustment method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0057] Step S201, obtaining the distribution of airbags.

[0058] For details, please see Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0059] Step S202: based on the distribution, the smart mattress is divided into a number of target areas, and the pressure signals of the airbags in the target areas are collected.

[0060] For details, please see Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0061] Step S203: determine the coverage range of the user based on the pressure signal, and obtain a first pressure within the coverage range.

[0062] For details, please see Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0063] In some optional embodiments, the pressure signal can be input into a pressure distribution model to determine the coverage of the user. The pressure distribution model can use statistical methods or machine learning methods to analyze the data to obtain the relationship between the airbag pressure and the coverage area. The data can be obtained by collecting the pressure signals of each airbag when users of different body shapes and postures lie on the smart mattress, as well as the actual contact range between the user, the body and the smart mattress.

[0064] Step S204, obtaining the posture information of the smart mattress, and setting a preset range based on the posture information.

[0065] Among them, the posture information of the smart mattress can be determined by installing sensors such as gyroscopes in the smart mattress, and then the changes in the center of gravity and pressure distribution of the human body in this posture can be calculated based on the posture information of the smart mattress. According to the changed center of gravity and pressure, the preset range can be adjusted to improve the user experience.

[0066] In an actual application, the foot of the smart mattress is raised by about 30° to 45°, and the head is raised by about 10° to 15°. In this state, the pressure of the lower shoulder of the human body on the smart mattress will change, and the preset range can be adjusted accordingly according to the change relationship.

[0067] Step S205, comparing the first pressure with the preset range, and determining the area to be adjusted based on the comparison result.

[0068] For details, please see Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0069] In some optional implementations, when the first pressure is not within a preset range, the target area corresponding to the first pressure is marked as an area to be adjusted.

[0070] When the first pressure is not within the preset range, the target area corresponding to the first pressure is marked as the area to be adjusted. It can be confirmed that the supporting force of the area to be adjusted is too strong or too weak. In subsequent adjustments, the target area is adjusted in a targeted manner, thereby improving the adaptability of the method.

[0071] Step S206, adjusting the gas volume of the airbag in the area to be adjusted until the pressure of the airbag in the area to be adjusted meets a preset range.

[0072] For details, please see Figure 1 Step S105 of the illustrated embodiment will not be described in detail here.

[0073] In some optional implementations, the above step S206 includes:

[0074] Step S2061, when the first pressure is less than the lower limit threshold of the preset range, the amount of gas in the airbag in the area to be adjusted is increased.

[0075] Step S2062, when the first pressure is greater than an upper threshold value of a preset range, reducing the amount of gas in the airbag in the area to be adjusted.

[0076] When the gas volume of the airbag in the area to be adjusted is adjusted, the first pressure can be continuously updated to prevent the occurrence of insufficient adjustment or overshoot.

[0077] In a practical application, the connection diagram between the control module and the airbag in the smart mattress is as follows: Figure 3 As shown, the control module is connected to the airbag gas circuit. The control module can adjust the gas volume of different airbags by issuing different instructions.

[0078] The smart mattress adjustment method provided in this embodiment sets and adjusts the preset range by acquiring the posture information of the smart mattress, which can improve the flexibility of the method.

[0079] In this embodiment, a smart mattress is provided, which includes an airbag layer, a sensor layer and a control module.

[0080] The airbag layer includes a plurality of independently inflated / deflated airbags.

[0081] Among them, the distribution of airbags can be set according to application requirements.

[0082] In some optional embodiments, the airbag layer includes a shoulder airbag group, a back airbag group, a waist airbag group, a hip airbag group, a thigh airbag group and a calf airbag group.

[0083] In some optional embodiments, the back airbag group, waist airbag group and hip airbag group include several airbags of a first volume; the shoulder airbag group and thigh airbag group include several airbags of a second volume, and the second volume is larger than the first volume; the calf airbag group includes several airbags of a third volume, and the third volume is larger than the second volume.

[0084] The number of airbags and the volume of airbags included in each airbag group can be determined according to actual conditions.

[0085] The sensing layer includes a plurality of pressure sensors for collecting the internal pressure signal of the airbag.

[0086] The pressure sensors correspond to the airbags in the airbag layer, and different pressure sensors can collect internal pressure signals of different airbags.

[0087] In some optional embodiments, the pressure sensor in the sensing layer can be directly placed in the airbag in the airbag layer.

[0088] The control module is connected to the pressure sensor in the sensing layer and the airbag in the airbag layer, and is used to control the inflation / deflation of the corresponding airbag based on the pressure signal collected by the pressure sensor in the sensing layer.

[0089] In specific implementation, the airbags can be distributed in the six key positions of the shoulder, back, waist, buttocks, thighs, and calves according to the principles of ergonomics. Assume that the ideal support pressure of each part of the human body is P 肩 , P 背 , P 腰 , P 臀 , P 大腿 , P 小腿 , the contact area between each part and the smart mattress is S 肩 , S 背 , S 腰 , S 臀 , S 大腿 , S 小腿 .

[0090] Then, for the airbags distributed in six positions, namely the shoulders, back, waist, buttocks, thighs and calves, the sensing layer is equipped with six pressure sensors to collect the internal pressure of the airbags in the six positions.

[0091] When the control module controls the inflation / deflation of the corresponding airbag according to the pressure signal collected by the pressure sensor, it is assumed that the pressure value monitored by the shoulder airbag pressure sensor is F 肩s , the corresponding ideal shoulder support pressure is P 肩i , the contact area between the shoulder and the mattress is S 肩 Similarly, the pressure values ​​monitored by the pressure sensors at the back, waist, buttocks, thighs, and calves are F 背S 、F 腰S 、F 臀S 、F 大腿S 、F 小腿S The ideal support pressures corresponding to the six positions are P 背i , P 腰i , P 臀i , P 大腿i , P 小腿iThe contact areas at the six locations are S 背 , S 腰 , S 臀 , S 大腿 , S 小腿 .

[0092] The control module can first calculate the actual pressure of each part, such as the actual pressure of the shoulder P 肩a As shown below:

[0093] P 肩a =F 肩s / S 肩 ;

[0094] Then, calculate the difference between the actual shoulder pressure and the ideal shoulder support pressure:

[0095] ΔP 肩 =P 肩i -P 肩a .

[0096] Similarly, the pressure difference ΔP at other parts can be obtained 背 , ΔP 腰 , ΔP 臀 , ΔP 大腿 , ΔP 小腿 .

[0097] Then the relationship between the airbag pressure, sensor pressure, airbag volume, etc. is set to P = f(V), that is, the functional relationship between the airbag gas pressure P and the airbag gas volume V. When ΔP 肩 >0, which means that the shoulder needs to increase the support force, and the control system will issue a gas volume ΔV to the shoulder airbag. 肩 The instruction makes the new shoulder pressure

[0098] P 肩new =f(V 肩o +ΔV 肩 )

[0099] Approaching P 肩i ; Among them, P 肩new Represents the shoulder pressure after executing the command, V 肩o Represents the original gas volume of the shoulder airbag.

[0100] On the contrary, when ΔP 肩 <0, the released gas volume ΔV is 肩 The instruction makes the new pressure

[0101] P 肩new =f(V 肩o -ΔV 肩 )

[0102] Approaching P肩i .

[0103] The airbags in other parts of the body, such as the back, waist, buttocks, thighs and calves, are adaptively adjusted according to the same principle.

[0104] By issuing inflation and deflation instructions to the airbags in six locations according to their corresponding pressure sensor data, the airbags in each location can adaptively adjust their filling level, thereby changing the hardness of the corresponding locations on the mattress, ultimately achieving a personalized support effect that perfectly fits different sleeping positions and body shapes, effectively protecting the human spine and improving sleep comfort.

[0105] Figure 4 A schematic diagram of the connection relationship between a control module, a pressure sensor and an airbag is provided, wherein the pressure sensor is connected to the airbag one by one, collects the gas pressure in the corresponding airbag, and then transmits the collected signal to the control module, which controls the inflation / deflation of the corresponding airbag.

[0106] After receiving the gas pressure collected by the pressure sensor, the control module will determine whether the support force provided by the corresponding airbag meets the user's needs. If it does not meet the user's needs, different control instructions can be issued to achieve independent inflation and deflation operations.

[0107] In some optional embodiments, the smart mattress further includes a support layer, which is located at the bottom of the smart mattress and includes a plurality of independent pocket springs.

[0108] In a practical application, the layered structure of a smart mattress is Figure 5 As shown, the mattress consists of a comfort layer, a memory foam layer, a regular sponge layer, an air bag layer and a support layer from top to bottom.

[0109] Among them, the thickness of the comfort layer can be 10 cm, and it can be made using advanced quilting technology. Assume that the contact area between the human body and the mattress is S, and the pressure exerted by the human body on the mattress is F. According to the pressure formula P=F / S, during the inflation and deflation of the airbag, the local support force of the mattress will change, thereby affecting the pressure distribution. Quilting technology allows the surface of the mattress to remain flat and smooth when the pressure changes, ensuring that the human body can feel excellent comfort when contacting the mattress, avoiding discomfort such as unevenness and rubbing caused by the movement of the airbag. This is because the uniform texture and structure formed by quilting allows the pressure to be relatively evenly distributed on the contact surface, ensuring comfort from a mechanical point of view.

[0110] The thickness of the memory foam layer can be 2 cm, and high-quality memory foam material can be used. The elastic modulus E of the memory foam m It has the characteristics of changing with temperature T and pressure F. Its stress-strain relationship can be approximately described by the extended form of Hooke's law:

[0111] σ=E m (T,F)ε

[0112] Among them, σ is stress and ε is strain. When the human body lies down, different parts of the body exert different pressures on the memory foam. i (i represents different body parts), E of memory foam m The characteristics enable it to adaptively change its shape according to the pressure and temperature of the human body, further fit the curve of the human body, provide the user with a comfortable wrapping feeling, and assist in dispersing the pressure of the human body.

[0113] For example, for waist pressure F 腰 , the corresponding strain is:

[0114] ε 腰 =σ 腰 / (E m (T,F 腰 ))

[0115] Among them, ε 腰 is the waist strain, σ 腰 This strain causes the memory foam to deform in the waist area to fit the waist curve of the human body and better support the waist.

[0116] The thickness of the ordinary sponge layer can be about 2 cm, and its elastic modulus is E s When subjected to pressure F, according to Hooke's law:

[0117] ΔL=(FL0) / (AE s )

[0118] Among them, ΔL is the deformation of the sponge in the pressure direction, L0 is the initial length of the sponge, and A is the force-bearing area. Therefore, the ordinary sponge layer can play a role in buffering and auxiliary support, and cooperate with the memory foam layer to enhance the overall elasticity and comfort of the mattress, so that the mattress can maintain good resilience under different usage conditions.

[0119] The thickness of the airbag layer can be 10 cm. According to the principle of ergonomics, it is distributed in the six key positions of the shoulder, back, waist, buttocks, thighs and calves. Assume that the ideal support pressure of each part of the human body is P 肩 , P 背 , P 腰 , P 臀 , P 大腿 , P 小腿 , the contact area between each part and the mattress is S 肩 , S 背 , S 腰 , S 臀 , S 大腿 , S 小腿According to the relationship between pressure and stress F = PS, in order to achieve ideal support for each part, medium-sized airbags are used at the shoulders and thighs. The size can be determined according to actual conditions. The medium-sized airbags used at the shoulders and thighs can provide a support force F 肩 (Medium airbag), F 大腿 (Medium airbag) satisfies the following formula:

[0120] F 肩 (Medium airbag) = P 肩 S 大腿 ;

[0121] F 大腿 (Medium airbag) = P 肩 S 大腿 ;

[0122] This provides moderate and uniform support for these two relatively wide areas that have their own characteristics in bearing pressure.

[0123] Small airbags are used in the back, waist and buttocks to fit the curves of these parts more precisely, achieve precise support, and better maintain the physiological curvature of the human spine. The size of the airbags can be determined according to actual conditions, that is,

[0124] F 背 (Small airbag) = P 背 S 背 ;

[0125] F 腰 (Small airbag) = P 腰 S 腰 ;

[0126] F 臀 (Small airbag) = P 臀 S 臀 ;

[0127] Large airbags are used in the calf position. Considering that the calf needs sufficient support to relax muscles during sleep, large airbags can provide sufficient support and comfortable wrapping. The size can be determined according to actual conditions to meet F 小腿 (Large airbag) = P 小腿 S 小腿 .

[0128] The thickness of the support layer can be about 12 cm, and the independent bag spring inside is covered with cotton felt from top to bottom. Assuming the stiffness coefficient of a single spring is k, when subjected to pressure F, according to Hooke's law, the deformation of the spring is Δx = F / k. Independent bag springs can expand and contract independently, effectively supporting the weight of the human body, reducing the vibration transmission caused by turning over and other actions, and improving sleep stability. The thicker design allows the spring layer to have more space to reasonably distribute the number and layout of springs, further optimizing the overall support effect on the human body. At the same time, the cotton felt plays a role in protecting the springs, reducing noise and further improving comfort.

[0129] In some optional embodiments, the smart mattress includes a bed frame, and a motor drive system is arranged in the bed frame:

[0130] The motor drive system is connected to the control module and is used to control the folding of the smart mattress based on instructions issued by the control module.

[0131] A variety of folding postures can be pre-set according to the application scenario, such as zero gravity posture, reading posture, and movie-watching posture, etc. The motor drive system drives the mattress to achieve a variety of postures according to the instructions issued by the control module.

[0132] In a practical application, after the motor drive system receives the zero-gravity posture command from the control module, it drives the foot of the mattress to rise by about 30°-45° and the head to rise by about 10°-15°. 肩z , calculate the new pressure:

[0133] P 肩z =F 肩z / S 肩 ,

[0134] Among them, P 肩z represents the shoulder pressure after the change, S 肩 Represents the shoulder contact area.

[0135] The shoulder pressure is compared with the pressure P in the ideal zero gravity posture. 肩zi Compare and calculate the pressure difference, and adjust the volume of the shoulder airbag according to the pressure difference, and the same applies to other parts. This makes the force on each part of the human body even in zero gravity, reduces spinal pressure, promotes blood circulation, and improves sleep quality.

[0136] This collaborative design of folding bed frame and adaptive mattress airbag has significant advantages. When switching between different postures, the mattress can quickly adapt to the changes in the shape of the bed frame, provide precise support for the human body, and avoid discomfort or uneven force on the spine caused by changes in the bed posture. Compared with traditional single-function beds, the embodiments of the present application can meet the needs of various life scenarios, such as sleeping, leisure, entertainment, etc., improve the utilization rate and flexibility of home space, and bring users a new home experience of convenience, comfort and health.
