[0002] As people pay more and more attention to health and sleep quality, smart mattresses are favored by more and more consumers. Smart mattresses can provide users with a more comfortable sleeping experience that better fits the physiological curve of the human body by adjusting the softness, hardness and support of the mattress.

[0003] In the prior art, some smart mattresses use a strip-shaped single-layer airbag design, and use an air pump to inflate and deflate the airbag to adjust the softness and hardness of the mattress. This design is difficult to achieve fine support adjustment of local areas of the mattress due to the limited number of airbags and the relatively simple arrangement. In addition, some smart mattresses use an array-type airbag layout, which can achieve more precise support adjustment, but its airbags need to be connected to the air pump through a complex air pipe, and a solenoid valve needs to be configured on the air pipe to achieve independent control of each airbag.

[0059] Embodiment 1

[0060] Figure 1 is a schematic diagram of the structure of a smart mattress provided by the first embodiment of the present invention. Figure 1As shown, the smart mattress includes a first airbag layer 1, a second airbag layer 2, and an inflation and deflation assembly 4; the first airbag layer 1 includes a plurality of first airbag units 01 arranged along a first direction and extending along a second direction; the first direction intersects with the second direction; the second airbag layer 2 is located on one side of the first airbag layer 1, and the second airbag layer 2 includes a plurality of second airbag units 02 arranged along the second direction and extending along the first direction; the overlapping points between each first airbag unit 01 and each second airbag unit 02 form a plurality of support points 3; the gas inlet 011 of each first airbag unit 01 is connected to the inflation and deflation assembly 4; the gas inlet 021 of each second airbag unit 02 is connected to the inflation and deflation assembly 4.

[0061] The smart mattress includes a first airbag layer 1 and a second airbag layer 2 located on one side of the first airbag layer 1. For example, the second airbag layer 2 can be located at the bottom of the first airbag layer 1, that is, the first airbag layer 1 and the second airbag layer 2 are arranged in an up-down stack. At the same time, the first airbag layer 1 includes a plurality of first airbag units 01 arranged in a first direction and extending in a second direction, each of which is not connected to each other and is closely arranged in the first direction; the second airbag layer 2 includes a plurality of second airbag units 02 arranged in a second direction and extending in the first direction, each of which is not connected to each other and is closely arranged in the second direction. The first direction intersects with the second direction, for example, the first direction and the second direction can be at an angle of 90°.

[0062] For example, continue to refer to Figure 1 , the first direction may be longitudinal, and the second direction may be transverse, that is, each first airbag unit 01 in the first airbag layer 1 is arranged longitudinally and extends transversely, and each second airbag unit 02 in the second airbag layer 2 is arranged transversely and extends longitudinally, so that the first airbag layer 1 and the second airbag layer 2 can cover the entire surface of the smart mattress. The first airbag unit 01 and the second airbag unit 02 can be understood as independent airbag structures, each airbag unit can be made of flexible materials, such as polyurethane materials, and an inflatable cavity structure is formed inside the airbag unit. By adjusting the gas filling amount inside the airbag unit, the shape and hardness of the airbag unit can be changed to provide different support forces for the human body. In addition, the overlapping points between the first airbag unit 01 and each second airbag unit 02 can form a plurality of support points 3, and each support point 3 is evenly distributed on the smart mattress in a matrix arrangement, so that the support points 3 can fully cover all parts of the smart mattress, ensuring that the user can get accurate support in all parts of the smart mattress. It can be understood that by adjusting the pressure values ​​of the first airbag unit 01 and the second airbag unit 02 forming the support point 3, the supporting force at the support point 3 can be adjusted, thereby providing different supporting effects for the user, so that the smart mattress can better fit the human body curve and provide uniform supporting force for the human body, thereby improving the user's sleep quality and comfort.

[0063] At the same time, each airbag unit is provided with a gas inlet, and the gas inlet 011 of each first airbag unit 01 is respectively connected to the inflation and deflation assembly 4, and the gas inlet 021 of each second airbag unit 02 is respectively connected to the inflation and deflation assembly 4, so that the inflation or deflation operation of the first airbag unit 01 and the second airbag unit 02 can be realized through the inflation and deflation assembly 4. Optionally, the inflation and deflation assembly 4 may include at least one air pump 40, and the gas inlet 011 of each first airbag unit 01 is connected to the air pump 40, and the gas inlet 021 of each second airbag unit 02 is connected to the air pump 40. Among them, the inflation and deflation assembly 4 may include one or more air pumps 40. In an exemplary embodiment, continue to refer to Figure 1 , the inflation and deflation assembly 4 may include an air pump 40, that is, each first airbag unit 01 and each second airbag unit 02 are connected to the same air pump 40, so that the air pump 40 can inflate or deflate each first airbag unit 01 and each second airbag unit 02 at the same time. In another exemplary embodiment, as Figure 2 As shown, the air pump 40 in the inflation and deflation assembly 4 may include a first air pump 41 and a second air pump 42, each first airbag unit 01 is connected to the first air pump 41, and each second airbag unit 02 is connected to the second air pump 42, so that the first air pump 41 can inflate or deflate each first airbag unit 01 at the same time, and the second air pump 42 can inflate or deflate each second airbag unit 02 at the same time. In another exemplary embodiment, as Figure 3 As shown, the air pump 40 in the inflation and deflation assembly 4 may include the same number of first air pumps 41 as the first airbag units 01 and the same number of second air pumps 42 as the second airbag units 02, so that each first air pump 41 can be connected to each first airbag unit 01 in a one-to-one correspondence, and each second air pump 42 can be connected to each second airbag unit 02 in a one-to-one correspondence, so that each first airbag unit 01 can be inflated or deflated by each first air pump 41, and each second airbag unit 02 can be inflated or deflated by each second air pump 42. The specific number of air pumps 40 in the inflation and deflation assembly 4 can be determined according to actual needs, and the embodiment of the present invention does not make specific limitations on this. For the convenience of description, without special limitations, the embodiments of the present invention take the air pump 40 in the inflation and deflation assembly 4 as including a first air pump 41 and a second air pump 42, and each first airbag unit 01 is connected to the first air pump 41, and each second airbag unit 02 is connected to the second air pump 42 as an example to exemplarily illustrate the technical solution of the embodiment of the present invention.

[0064] Specifically, when the first airbag unit 01 is inflated by the first air pump 41 and the second airbag unit 02 is inflated by the second air pump 42, the internal pressure of the first airbag unit 01 and the second airbag unit 02 will gradually increase, causing the first airbag unit 01 and the second airbag unit 02 to expand and harden, thereby providing greater supporting force for the supporting point 3 formed by the first airbag unit 01 and the second airbag unit 02; conversely, when the first airbag unit 01 is deflated by the first air pump 41 and the second airbag unit 02 is deflated by the second air pump 42, the internal pressure of the first airbag unit 01 and the second airbag unit 02 will decrease, causing the first airbag unit 01 and the second airbag unit 02 to become soft, thereby reducing the supporting force at the supporting point 3 formed by the first airbag unit 01 and the second airbag unit 02. Exemplarily, the gas inside the first airbag unit 01 and the second airbag unit 02 can be air, nitrogen or other safe inert gas. By controlling the filling and release of the gas inside the airbag unit, the smart mattress can accurately adjust the supporting force at each supporting point, so that the smart mattress can dynamically adapt to the user's body changes and provide the user with a supporting effect that fits the human body curve. In addition, compared with the method of separately setting an airbag at each supporting point 3 and adjusting the pressure value of each supporting point 3 by adjusting the amount of gas in the separately set airbag, the method of adjusting the pressure value at the supporting point 3 by adjusting the amount of gas in the first airbag unit 01 and the second airbag unit 02 forming the supporting point 3 can achieve accurate adjustment of the pressure of the smart mattress with fewer airbag units and air pumps, thereby reducing hardware and design costs and effectively improving the adjustment speed and response efficiency of the smart mattress.

[0065] Optional, continue to refer to Figure 2 The smart mattress may further include a plurality of first pressure sensors 51 and a plurality of second pressure sensors 52; each first pressure sensor 51 is respectively arranged in one-to-one correspondence with each first airbag unit 01; each second pressure sensor 52 is respectively arranged in one-to-one correspondence with each second airbag unit 02.

[0066] Among them, the first pressure sensor 51 can be specifically understood as a sensor device for measuring the pressure in each first airbag unit 01, and the second pressure sensor 52 can be specifically understood as a sensor device for measuring the pressure in each second airbag unit 02. Exemplarily, the first pressure sensor 51 and the second pressure sensor 52 can be a piezoresistive pressure sensor, a piezoelectric pressure sensor or a capacitive pressure sensor. Specifically, each first pressure sensor 51 is set in a one-to-one correspondence with each first airbag unit 01, and each second pressure sensor 52 is set in a one-to-one correspondence with each second airbag unit 02, and each first pressure sensor 51 and each second pressure sensor 52 can be electrically connected to the controller of the smart mattress. When the user lies on the smart mattress, the first pressure sensor 51 can convert the measured pressure in the first airbag unit 01 into an electrical signal and transmit it to the controller, and the second pressure sensor 52 can convert the measured pressure in the second airbag unit 02 into an electrical signal and transmit it to the controller. The support point 3 is formed by the overlap of the first airbag unit 01 and the second airbag unit 02. Therefore, by processing the electrical signals transmitted by the first pressure sensor 51 and the second pressure sensor 52, the controller can determine the pressure value at the support point 3 formed by the first airbag unit 01 corresponding to the first pressure sensor 51 and the second airbag unit 02 corresponding to the second pressure sensor 52. When the user lies on the smart mattress, different characteristic parts of the human body will exert different pressures on each support point 3. The controller of the smart mattress determines the pressure value at each support point 3, so that the smart mattress can accurately detect the force conditions of each characteristic part of the human body, and enables the controller of the smart mattress to inflate or deflate each first airbag unit 01 and the second airbag unit 02 according to the pressure information, so as to improve the accuracy and stability of the pressure adjustment of the smart mattress, thereby improving the sleep quality and comfort of the user. In addition, compared with separately setting a pressure sensor at each supporting point 3, setting a first pressure sensor 51 and a second pressure sensor 52 corresponding to each first airbag unit and each second airbag unit respectively can reduce the measurement modules in the smart mattress, thereby simplifying the system structure of the smart mattress and improving the efficiency and stability of the smart mattress adjustment.

[0067] It can also be understood that the first pressure sensor 51 can be set in the gas pipeline between the gas inlet 011 of the first airbag unit 01 and the gas outlet 411 of the first air pump 41, and the second pressure sensor 52 can be set in the gas pipeline between the gas inlet 021 of the second airbag unit 02 and the gas outlet 421 of the second air pump 42, so that the first pressure sensor 51 can determine the pressure value of the first airbag unit 01 according to the pressure value in the gas pipeline between the gas inlet 011 of the first airbag unit 01 and the gas outlet 411 of the first air pump 41, and the second pressure sensor 52 can determine the pressure value of the second airbag unit 02 according to the pressure value in the gas pipeline between the gas inlet 021 of the second airbag unit 02 and the gas outlet 421 of the second air pump 42, thereby improving the accuracy and stability of pressure detection of the smart mattress.

[0068] Optional, continue to refer to Figure 2 The inflation and deflation assembly 4 may further include a plurality of first valves 61 and a plurality of second valves 62; each first valve 61 is respectively arranged in one-to-one correspondence with each first airbag unit 01; each second valve 62 is respectively arranged in one-to-one correspondence with each second airbag unit 02.

[0069] Specifically, the first valve 61 can be set in the gas pipeline between the gas inlet 011 of the corresponding first airbag unit 01 and the gas outlet 411 of the first air pump 41, and at the same time, the first valve 61 is located between the first pressure sensor 51 in the gas pipeline and the gas outlet 411 of the first air pump 41; the second valve 62 can be set in the gas pipeline between the gas inlet 021 of the corresponding second airbag unit 02 and the gas outlet 421 of the second air pump 42, and at the same time, the second valve 62 is located between the second pressure sensor 52 in the gas pipeline and the gas outlet 421 of the second air pump 42. When the first air pump 41 does not inflate or deflate the first airbag unit 01, and the second air pump 42 does not inflate or deflate the second airbag unit 02, the first valve 61 and the second valve 62 are in a closed state, so that the first pressure sensor 51 can determine the pressure value of the first airbag unit 01 according to the pressure value in the gas pipeline, and the second pressure sensor 52 can determine the pressure value of the second airbag unit 02 according to the pressure value in the gas pipeline, and can further determine the pressure value of each supporting point 3. When the first airbag unit 01 is inflated or deflated by the first air pump 41, and the second airbag unit 02 is inflated or deflated by the second air pump 42, the first valve 61 and the second valve 62 are in an open state to establish an airflow path between the first air pump 41 and the first airbag unit 01, and between the second air pump 42 and the second airbag unit 02, so as to realize the inflation or deflation operation of the first airbag unit 01 and the second airbag unit 02. When the gas filling amount in the first airbag unit 01 and the second airbag unit 02 reaches the target value, that is, when the supporting force at the supporting point 3 corresponding to the first airbag unit 01 and the second airbag unit 02 reaches the required supporting force, the first valve 61 and the second valve 62 are closed to isolate the airflow path, thereby effectively preventing gas leakage or external pressure changes from affecting the pressure in the first airbag unit 01 and the second airbag unit 02. Through the coordinated control of the first valve 61 and the second valve 62, the gas filling amount in the first airbag unit 01 and the second airbag unit 02 can be accurately adjusted, and the air pressure in the first airbag unit 01 and the second airbag unit 02 can be ensured to be stable, thereby improving the accuracy and stability of the pressure adjustment of the smart mattress.

[0070] It can also be understood that the first valve 61 and the second valve 62 can be electromagnetic valves, so that the amount of gas entering each first airbag unit 01 and each second airbag unit 02 can be accurately controlled by adjusting the opening and closing time of each first valve 61 and the second valve 62. Figure 2, each first airbag unit 01 is connected to the same first air pump 41, and each second airbag unit 02 is connected to the same second air pump 42. When the first air pump 41 is used to inflate or deflate the plurality of first airbag units 01, the opening and closing time of each first valve 61 corresponding to each first airbag unit 01 can be adjusted respectively to precisely control the amount of gas entering or flowing out of each first airbag unit 01, thereby precisely controlling the amount of gas filled in each first airbag unit 01. At the same time, when the second air pump 42 is used to inflate or deflate the plurality of second airbag units 02, the opening and closing time of each second valve 62 corresponding to each second airbag unit 02 can be adjusted respectively to precisely control the amount of gas entering or flowing out of each second airbag unit 02, thereby precisely controlling the amount of gas filled in each second airbag unit 02. By controlling the gas filling amount of each first airbag unit 01 and each second airbag unit 02 through the same first air pump 41 or the same second air pump 42, the number of air pumps can be significantly reduced, thereby reducing hardware and design costs.

[0071] In addition, the inflation and deflation assembly 4 may also include an exhaust valve, so that each first airbag unit 01 and each second airbag unit 02 can be exhausted through the exhaust valve, thereby improving the exhaust efficiency and enhancing the efficiency and stability of the pressure regulation of the smart mattress.

[0072] Optionally, the smart mattress may further include a controller, which is used to execute the pressure regulation method of the smart mattress provided in an embodiment of the present invention. The pressure regulation method of the smart mattress may include obtaining the actual pressure at each support point 3 in real time; determining the target pressure of each support point 3 according to the actual pressure at each support point 3; and controlling the working state of each first air pump 41 and each second air pump 42 according to the actual pressure and target pressure of each support point 3.

[0073] It can be understood that the controller in the smart mattress can execute the pressure regulation method of the smart mattress provided in the embodiment of the present invention, and has functional modules and beneficial effects corresponding to the execution method.

[0077] Specifically, each first airbag unit of the smart mattress is provided with a first pressure sensor in one-to-one correspondence, and each second airbag unit of the smart mattress is provided with a second pressure sensor in one-to-one correspondence, so that the first pressure sensor and the second pressure sensor can respectively transmit the measured pressure in the first airbag unit and the second airbag unit to the controller as an electrical signal, so that the controller can determine the pressure value at the support point formed by the first airbag unit corresponding to the first pressure sensor and the second airbag unit corresponding to the second pressure sensor. When the user lies on the smart mattress, different characteristic parts of the human body will exert different pressures on each support point. By determining the actual pressure at each support point, the controller enables the smart mattress to accurately detect the force conditions of each characteristic part of the human body, and provides a data basis for the subsequent determination of the target pressure of each support point and the control of the working state of each inflation and deflation component.

[0078] S102: Determine the target pressure of each supporting point according to the actual pressure at each supporting point.

[0079] Specifically, after determining the actual pressure at each support point according to the pressure value of each first airbag unit detected by each first pressure sensor and the pressure value of each second airbag unit detected by each second pressure sensor, the controller of the smart mattress can determine the target pressure of each support point according to the actual pressure at each support point and the actual sleeping state of the user on the smart mattress. Exemplarily, according to the actual pressure at each support point, the controller of the smart mattress can determine the characteristic parts of the user corresponding to each support point, such as shoulders, waist or buttocks, etc., and can determine the target pressure of the support point according to the preset comfortable pressure range of these characteristic parts. Accurately determining the target pressure of each support point according to the actual pressure at each support point provides a data basis for the subsequent control of the working state of each inflation and deflation component, so that the smart mattress can flexibly adjust the pressure value of each support point according to the different sleeping states of the user, ensuring that the smart mattress can provide appropriate support force for the key force characteristic parts of the human body in the current sleeping state, so as to provide the user with a support effect that fits the human body curve. At the same time, the controller of the smart mattress can dynamically optimize the target pressure of each support point according to the changes in the actual pressure at each support point in real time. That is, the smart mattress can optimize the pressure value of each support point of the smart mattress in real time according to the changes in the user's sleep state during sleep, so as to improve the comfort of the smart mattress, meet the user's personalized sleep needs, and improve the user's sleep quality.

[0080] S103, controlling the working state of the inflation and deflation components according to the actual pressure and target pressure of each supporting point.

[0081] Specifically, after determining the actual pressure and target pressure of each support point, the controller of the smart mattress can determine the pressure value that needs to be adjusted at each support point, and can further determine the amount of gas that needs to be filled or released by the first airbag unit and the second airbag unit corresponding to the support point according to the pressure value that needs to be adjusted at each support point. After determining the amount of gas that needs to be filled or released by the first airbag unit and the second airbag unit corresponding to the support point, the controller of the smart mattress can correspondingly control the air pump in the inflation and deflation assembly connected to the first airbag unit and the air pump in the inflation and deflation assembly connected to the second airbag unit to perform inflation or deflation operations to adjust the actual pressure at each support point to the target pressure. By accurately adjusting the working state of each air pump, it is ensured that the smart mattress can provide users with continuous and personalized comfortable support throughout the user's sleep process, improve the accuracy and stability of the pressure adjustment of the smart mattress, and thus significantly improve the user's sleep quality and comfort.

[0082] Optionally, before determining the target pressure of each supporting point according to the actual pressure at each supporting point, the method further includes: filtering and calibrating the actual pressure at each supporting point.

[0083] Specifically, before determining the target pressure of each support point according to the actual pressure at each support point, the controller of the smart mattress first filters and calibrates the actual pressure at each support point. Exemplarily, the filtering method may be low-pass filtering, median filtering, Kalman filtering, or weighted average filtering, etc. The actual pressure at each support point is filtered and calibrated to effectively remove noise caused by external interference, sensor error, etc., to ensure the accuracy and stability of the actual pressure at each support point, so that the subsequent target pressure calculation of each support point can be based on more reliable pressure data, thereby improving the accuracy and stability of the pressure adjustment of the smart mattress.

[0084] In this embodiment, the actual pressure at each support point is obtained in real time, so that the controller of the smart mattress can determine the target pressure of each support point according to the actual pressure at each support point and the actual sleeping state of the user on the smart mattress, so that the smart mattress can flexibly adjust the pressure value of each support point according to the different sleeping states of the user, ensuring that the smart mattress can provide appropriate support force at the key force characteristic parts of the human body in the current sleeping state, so as to provide the user with a support effect that fits the human body curve. At the same time, the controller of the smart mattress can determine the pressure value that needs to be adjusted at each support point according to the actual pressure and the target pressure of each support point, and can further determine the amount of gas that needs to be filled or released by the first airbag unit and the second airbag unit corresponding to the support point according to the pressure value that needs to be adjusted at each support point, so that the controller of the smart mattress can correspondingly control the inflation and deflation components connected to the first airbag unit and the second airbag unit to perform inflation or deflation operations, so that the actual pressure at each support point can be adjusted to the target pressure, ensuring that the smart mattress can provide the user with continuous and personalized comfortable support throughout the user's sleep process, improving the accuracy and stability of the pressure adjustment of the smart mattress, and significantly improving the user's sleep quality and comfort.

[0085] Embodiment 3

[0086] Figure 5 is a flow chart of a pressure adjustment method of a smart mattress provided in the third embodiment of the present invention. Based on the above embodiment, this embodiment describes in detail the method for obtaining the actual pressure at each supporting point in real time. Figure 5 As shown, the pressure adjustment method of the smart mattress of this embodiment may include:

[0087] S201. Acquire in real time the pressure information of each first airbag unit collected by each first pressure sensor.

[0088] Specifically, each first pressure sensor is arranged in a one-to-one correspondence with each first airbag unit, and each first pressure sensor can be electrically connected to the controller of the smart mattress. When the user lies on the smart mattress, the first pressure sensor can convert the measured pressure in the first airbag unit into an electrical signal and transmit it to the controller, so that the controller can obtain the pressure information of each first airbag unit in real time, providing a data basis for the subsequent determination of the actual pressure at each support point.

[0089] S202: Acquire in real time the pressure information of each second airbag unit collected by each second pressure sensor.

[0090] Specifically, each second pressure sensor is arranged in a one-to-one correspondence with each second airbag unit, and each second pressure sensor can be electrically connected to the controller of the smart mattress. When the user lies on the smart mattress, the second pressure sensor can convert the measured pressure in the second airbag unit into an electrical signal and transmit it to the controller, so that the controller can obtain the pressure information of each second airbag unit in real time, providing a data basis for the subsequent determination of the actual pressure at each support point.

[0091] S203 . Determine actual pressures at supporting points corresponding to the first airbag units and the second airbag units according to the pressure information of each first airbag unit and the pressure information of each second airbag unit.

[0092] Specifically, the support point is formed by the overlap of the first airbag unit and the second airbag unit. Therefore, after the controller obtains the pressure information of each first airbag unit and the pressure information of each second airbag unit in real time, the controller can determine the pressure value at the support point formed by the first airbag unit corresponding to the first pressure sensor and the second airbag unit corresponding to the second pressure sensor. When the user lies on the smart mattress, different characteristic parts of the human body will exert different pressures on each support point. The controller of the smart mattress determines the pressure value at each support point, so that the smart mattress can accurately detect the force conditions of each characteristic part of the human body, and enables the controller of the smart mattress to inflate or deflate each first airbag unit and the second airbag unit according to the pressure information, so as to improve the accuracy and stability of the pressure adjustment of the smart mattress, thereby improving the user's sleep quality and comfort.

[0093] It can be understood that the pressure value at the supporting point can be the sum of the pressure value of the first airbag unit corresponding to the supporting point and the pressure value of the second airbag unit corresponding to the supporting point. i is the pressure value of the first airbag unit in the i-th row of the first airbag layer, b j is the pressure value of the second airbag unit in the jth column of the second airbag layer, c ij is the pressure value of the support point located in the i-th row and the j-th column, then a i 、b j and c ij The relationship between them can be: ij =a i +b j, where i≥1, j≥1. When the first airbag layer of the smart mattress includes two rows of first airbag units, and the second airbag layer of the smart mattress includes two columns of second airbag units, if the pressure value of the first row of airbag units is 10Pa, the pressure value of the second row of airbag units is 8Pa, the pressure value of the first column of airbag units is 8Pa, and the pressure value of the second column of airbag units is 7Pa, then the pressure value of the support point located in the first row and the first column is 18Pa, the pressure value of the support point located in the first row and the second column is 17Pa, the pressure value of the support point located in the second row and the first column is 16Pa, and the pressure value of the support point located in the second row and the second column is 15Pa. By determining the actual pressure at the support point corresponding to the first airbag unit and the second airbag unit through the pressure information of the first airbag unit measured by the first pressure sensor and the pressure information of the second airbag unit measured by the second pressure sensor, the measurement module in the smart mattress can be reduced, thereby simplifying the system structure of the smart mattress and improving the efficiency and stability of the smart mattress adjustment.

[0094] S204: Determine the target pressure of each supporting point according to the actual pressure at each supporting point.

[0095] S205. Control the working state of the inflation and deflation components according to the actual pressure and target pressure of each supporting point.

[0096] In this embodiment, by acquiring in real time the pressure information of each first airbag unit collected by each first pressure sensor, and acquiring in real time the pressure information of each second airbag unit collected by each second pressure sensor, the controller of the smart mattress can determine the actual pressure at the supporting points corresponding to the first airbag unit and the second airbag unit according to the pressure information of each first airbag unit and the pressure information of each second airbag unit, so that the smart mattress can accurately detect the force conditions of various characteristic parts of the human body, and the controller of the smart mattress can inflate or deflate each first airbag unit and the second airbag unit according to the pressure information, so as to improve the accuracy and stability of the pressure regulation of the smart mattress, thereby improving the sleep quality and comfort of the user.

[0097] Embodiment 4

[0098] Figure 6 is a flow chart of a pressure adjustment method of a smart mattress provided in a fourth embodiment of the present invention. Based on the above embodiments, this embodiment describes in detail a method for determining a target pressure of each support point according to the actual pressure at each support point. Accordingly, Figure 6 As shown, the pressure adjustment method of the smart mattress of this embodiment may include:

[0099] S301, obtaining the actual pressure at each supporting point in real time.

[0100] S302: Determine the characteristic parts corresponding to each supporting point according to the actual pressure of each supporting point.

[0101] Specifically, the controller of the smart mattress can determine the actual pressure at each support point according to the pressure value of each first airbag unit detected by each first pressure sensor and the pressure value of each second airbag unit detected by each second pressure sensor. The actual pressure of the support point reflects the degree of force at the point. The controller of the smart mattress can match each support point with the characteristic part of the user according to the actual pressure at each support point and the pressure distribution law of the preset characteristic part. For example, the shoulders usually have higher local pressure, the waist has a greater pressure concentration, and the buttocks usually form a more obvious pressure distribution. By determining the characteristic part corresponding to each support point, it provides a basis for the subsequent determination of the user's current sleeping posture, so that the smart mattress can optimize the pressure value of each support point according to the user's sleeping posture, thereby meeting the user's personalized sleeping needs.

[0102] S303: Determine the current sleeping posture according to the characteristic parts corresponding to each support point.

[0103] Specifically, the controller of the smart mattress can determine the user's current sleeping posture by analyzing the actual pressure of each support point and the characteristic parts corresponding to each support point. For example, the sleeping posture can be supine, side-lying or prone, etc. In a feasible embodiment, the controller of the smart mattress can identify the pressure distribution pattern of the user's current sleep by performing real-time analysis on the actual pressure of each support point and the characteristic parts corresponding to each support point, and can infer the user's current sleeping posture according to the pressure distribution pattern and the mapping relationship between the preset sleeping posture and pressure distribution. For example, the mapping relationship between sleeping posture and pressure distribution can include that when the user is in a supine state, the pressure distribution of the smart mattress is usually concentrated in the back, middle waist and buttocks, while the pressure on the shoulders and legs is low; when the user is in a side-lying state, the pressure on the shoulders and hips is large, while the pressure on the back and abdomen is relatively light. By accurately identifying the user's sleeping posture, the controller of the smart mattress can accurately adjust the support force of each part of the smart mattress according to the needs of different sleeping postures of the user to improve the comfort of the smart mattress. In addition, the controller of the smart mattress can also dynamically optimize the target pressure of each support point according to the changes in the user's sleeping posture in real time, thereby further improving the user's sleep quality.

[0104] S304: Determine the comfortable pressure range of each characteristic part according to the current sleeping posture.

[0105] Specifically, the controller of the smart mattress can determine the comfortable pressure range required for each characteristic part of the user, such as the shoulder, waist or buttocks, according to the current sleeping posture of the user. It is understandable that different sleeping postures will cause the pressure distribution of the body to change, thereby affecting the pressure value required for each characteristic part. The controller of the smart mattress may include preset ideal pressure ranges for each characteristic part in each sleeping posture, and these preset comfortable pressure ranges can be determined based on the pressure distribution characteristics under different sleeping postures, and can be established through ergonomic research and a large amount of user feedback data. Exemplarily, the ideal pressure range of each characteristic part in each sleeping posture may include that when the user lies on his back, the waist, back and buttocks will be under greater pressure, while the pressure on the shoulders and head is less, therefore, the preset comfortable pressure range of the waist and buttocks is higher, while the preset comfortable pressure range of the shoulders is lower; when the user lies on his side, the pressure on the shoulders and buttocks will increase, while the pressure on the back and legs is lighter, therefore, the preset comfortable pressure range of the shoulders and buttocks is higher, while the preset comfortable pressure range of the back and legs is lower. By determining the comfortable pressure range of each characteristic part according to the user's sleeping posture, the smart mattress can provide support that is more in line with the human physiological curve, helping to reduce local fatigue and discomfort of the body and improve the user's sleep quality.

[0106] In addition, the controller of the smart mattress can also dynamically optimize the target pressure of each support point in real time according to the changes in the user's sleeping posture. For example, when the user switches from a supine posture to a side-lying posture, the smart mattress can increase the preset pressure range of the shoulders and buttocks, and reduce the preset pressure range of the waist. At the same time, it can increase the target pressure of the support points corresponding to the shoulders and buttocks, and reduce the target pressure of the support points corresponding to the waist to ensure that the pressure of each characteristic part is in the optimal comfort range. It can also be understood that the smart mattress can also be personalized according to the user's personal habits and health needs. Adjust the comfortable pressure range of each characteristic part. For example, the user may have special support requirements for the waist or neck, and the smart mattress can fine-tune the preset pressure range of the waist or neck according to these requirements to provide users with a personalized comfort experience.

[0107] S305: Determine the target pressure value of each supporting point according to the comfortable pressure range of each characteristic part.

[0108] After the controller of the smart mattress determines the comfortable pressure range required for each characteristic part of the user according to the user's current sleeping posture, it can further determine the target pressure value of each support point corresponding to each characteristic part. For example, the target pressure value of the support point can be the middle value of the determined comfortable pressure range, thereby providing a data basis for the subsequent control of the working state of each inflation and deflation component, so that the smart mattress can flexibly adjust the pressure value of each support point according to the different sleeping postures of the user, ensuring that the smart mattress can provide appropriate support force for the key stress characteristic parts of the human body in the current sleeping posture, so as to provide the user with a support effect that fits the human body curve, meet the user's personalized sleep needs, improve the accuracy and stability of the pressure adjustment of the smart mattress, and improve the user's sleep quality and comfort.

[0109] S306: Control the working state of the inflation and deflation components according to the actual pressure and target pressure of each supporting point.

[0110] In this embodiment, each support point is matched with the characteristic part of the user according to the actual pressure of each support point, so that the characteristic part corresponding to each support point can be determined. The current sleeping posture of the user can be determined according to the actual pressure of each support point and the characteristic part corresponding to each support point, and the comfortable pressure range required for each characteristic part of the user can be further determined according to the current sleeping posture of the user, so that the target pressure value of each support point can be determined according to the comfortable pressure range of each characteristic part, so that the controller of the smart mattress can accurately adjust the support force of each part of the smart mattress according to the needs of different sleeping postures of the user, so that the smart mattress can provide support that is more in line with the physiological curve of the human body, meet the personalized sleeping needs of the user, improve the accuracy and stability of the pressure adjustment of the smart mattress, and improve the sleep quality and comfort of the user.

[0111] Embodiment 5

[0112] Figure 7 is a flow chart of a pressure regulating method of a smart mattress provided in Embodiment 5 of the present invention. Based on the above embodiments, this embodiment describes in detail a method for controlling the working state of the inflation and deflation components according to the actual pressure and target pressure of each supporting point. Figure 7 As shown, the pressure adjustment method of the smart mattress of this embodiment may include:

[0113] S401. Obtain the actual pressure at each supporting point in real time.

[0114] S402: Determine the target pressure of each supporting point according to the actual pressure at each supporting point.

[0115] S403: Determine the pressure difference between the actual pressure of the support point and the target pressure according to the actual pressure of the support point and the target pressure.

[0116] Specifically, the controller of the smart mattress can determine the pressure difference between the actual pressure and the target pressure of the support point according to the actual pressure and the target pressure of the support point. The pressure difference can be positive or negative. When the pressure difference is positive, it means that the actual pressure is higher than the target pressure; when the pressure difference is negative, it means that the actual pressure is lower than the target pressure; when the pressure difference is zero, it means that the actual pressure is the same as the target pressure, and there is no need to adjust the actual pressure of the support point. By determining the pressure difference, a data basis is provided for the subsequent control of the working status of each air pump, so that the smart mattress can flexibly adjust the pressure value of each support point according to the different sleeping postures of the user, thereby improving the user's sleep quality and comfort.

[0117] S404. Control the working state of the air pump connected to the first airbag unit corresponding to the supporting point and the working state of the air pump connected to the second airbag unit corresponding to the supporting point according to the pressure difference of the supporting point.

[0118] The inflation and deflation assembly includes at least one air pump, and the gas inlet of each first airbag unit is connected to the air pump, and the gas inlet of each second airbag unit is connected to the air pump. Specifically, the controller of the smart mattress can determine the amount of gas required to inflate or deflate the first airbag unit and the second airbag unit corresponding to the support point according to the pressure difference of the support point, and can control the air pump connected to the first airbag unit to inflate or deflate the first airbag unit corresponding to the support point according to the amount of gas required, and control the air pump connected to the second airbag unit to inflate or deflate the second airbag unit corresponding to the support point according to the amount of gas required, so that the actual pressure of the support point reaches the target pressure, ensuring that the smart mattress can provide users with continuous and personalized comfort support throughout the user's sleep process, improving the accuracy and stability of the pressure regulation of the smart mattress, thereby significantly improving the user's sleep quality and comfort.

[0119] It is understandable that, according to the pressure difference of the support point, determining the amount of gas required to inflate or deflate the first airbag unit and the second airbag unit corresponding to the support point can be achieved by an ideal solution method. i is the pressure value that needs to be adjusted for the first airbag unit in the i-th row of the first airbag layer, B j is the pressure value that needs to be adjusted for the second airbag unit in the jth column of the second airbag layer, C ij is the pressure difference between the support points located in the i-th row and the j-th column, then A i , Bj and C ij The relationship between them can be: ij ≥A i +B j , where i≥1, j≥1. When the first airbag layer of the smart mattress includes two rows of first airbag units, and the second airbag layer of the smart mattress includes two columns of second airbag units, if the absolute value of the pressure difference of the support points located in the first row and the first column is 10Pa, the absolute value of the pressure difference of the support points located in the first row and the second column is 8Pa, the absolute value of the pressure difference of the support points located in the second row and the first column is 8Pa, and the absolute value of the pressure difference of the support points located in the second row and the second column is 7Pa, then the following four inequalities can be solved: A1+B1 ≤10, A1+B2≤8, A2+B1≤8, A2+B2≤7, the ideal solution that maximizes the value of the objective function Y, objective function Y=A1+A2+B1+B2, so that the values ​​of A1, A2, B1 and B2 can be determined, wherein A1 is the pressure value that needs to be adjusted for the first airbag unit in the first row, A2 is the pressure value that needs to be adjusted for the first airbag unit in the second row, B1 is the pressure value that needs to be adjusted for the second airbag unit in the first column, and B2 is the pressure value that needs to be adjusted for the second airbag unit in the second column. After calculating the pressure values ​​that need to be adjusted for each first airbag unit and each second airbag unit, the controller of the smart mattress can calculate the amount of gas that needs to be inflated or deflated for each first airbag unit and the amount of gas that needs to be inflated or deflated for each second airbag unit according to the pressure value and the volume of each airbag unit, so that the controller of the smart mattress can control the working state of each air pump accordingly. By adjusting the amount of gas in the first airbag unit and the second airbag unit that form the support point, the pressure value at the support point can be adjusted. The pressure of the smart mattress can be accurately adjusted with fewer airbag units and air pumps, thereby reducing hardware and design costs and effectively improving the adjustment speed and response efficiency of the smart mattress.

[0120] It can also be understood that the pressure values ​​of the first airbag unit and the second airbag unit can be discretized according to a certain range. For example, the pressure values ​​of the first airbag unit and the second airbag unit can be divided into 100 discrete levels, each level representing a specific pressure value range. When the pressure of the first airbag unit and the second airbag unit varies between 0Pa and 1000Pa, it can be divided into 100 levels, and the pressure value of each level differs by a certain range, that is, the pressure increases by 10Pa at each level, so that the control unit of the smart mattress only needs to adjust the pressure of the first airbag unit and the second airbag unit according to the level without having to process the precise pressure value, which helps to simplify the calculation process and improve the efficiency and stability of the pressure regulation of the smart mattress.

[0121] Optional, such as Figure 8 As shown, according to the pressure difference of the supporting point, the working state of the air pump connected to the first airbag unit corresponding to the supporting point and the working state of the air pump connected to the second airbag unit corresponding to the supporting point are controlled, including:

[0122] S4041, determine whether the pressure difference of the support point is equal to zero; if not, execute S4042 or S4043;

[0123] Specifically, by judging whether the pressure difference of the support point is equal to zero, it can be judged whether the actual pressure of each support point needs to be adjusted. When the pressure difference of the support point is equal to zero, it means that the actual pressure of the support point is the same as the target pressure, and there is no need to adjust the actual pressure of the support point. When the pressure difference of the support point is not equal to zero, it means that there is a deviation between the actual pressure of the support point and the target pressure, and the actual pressure of the support point needs to be adjusted so that the actual pressure of the support point is adjusted to the target pressure, thereby improving the user's sleep quality and comfort.

[0124] When the pressure difference of the support point is not equal to zero, it is necessary to continue to determine whether the pressure difference of the support point is greater than zero, so as to determine the relationship between the actual pressure of each support point and the target pressure, so as to determine whether the first airbag unit and the second airbag unit corresponding to the support point need to be inflated or deflated.

[0125] S4042. When the pressure difference is greater than zero, control the air pump connected to the first airbag unit corresponding to the support point to deflate the first airbag unit, and / or control the air pump connected to the second airbag unit corresponding to the support point to deflate the second airbag unit.

[0126] Specifically, when the pressure difference of the support point is greater than zero, it means that the actual pressure is higher than the target pressure, and the first airbag unit and the second airbag unit corresponding to the support point need to be deflated. After calculating the amount of gas that needs to be deflated in the first airbag unit and the amount of gas that needs to be deflated in the second airbag unit by the pressure difference of the support point and the ideal solution, the controller of the smart mattress can control the air pump connected to the first airbag unit corresponding to the support point to deflate the first airbag unit, and / or control the air pump connected to the second airbag unit corresponding to the support point to deflate the second airbag unit. By deflating the first airbag unit and the second airbag unit, the amount of gas in the first airbag unit and the second airbag unit can be reduced, thereby reducing the pressure value at the support point formed by the first airbag unit and the second airbag unit, so that the actual pressure at the support point can be adjusted to the target pressure. By controlling the release of the gas inside the airbag unit, the smart mattress can accurately adjust the support force at each support point, so that the smart mattress can dynamically adapt to the user's body changes and provide the user with a support effect that fits the human body curve.

[0127] S4043. When the pressure difference is less than zero, control the air pump connected to the first airbag unit corresponding to the support point to inflate the first airbag unit, and / or control the air pump connected to the second airbag unit corresponding to the support point to inflate the second airbag unit.

[0128] Specifically, when the pressure difference of the support point is less than zero, it means that the actual pressure is lower than the target pressure, and the first airbag unit and the second airbag unit corresponding to the support point need to be inflated. After calculating the amount of gas required to inflate the first airbag unit and the amount of gas required to inflate the second airbag unit by the pressure difference of the support point and the ideal solution, the controller of the smart mattress can control the air pump connected to the first airbag unit corresponding to the support point to inflate the first airbag unit, and / or control the air pump connected to the second airbag unit corresponding to the support point to inflate the second airbag unit. By inflating the first airbag unit and the second airbag unit, the amount of gas in the first airbag unit and the second airbag unit can be increased, so that the pressure value at the support point formed by the first airbag unit and the second airbag unit can be increased, so that the actual pressure at the support point can be adjusted to the target pressure. By controlling the filling of gas inside the airbag unit, the smart mattress can accurately adjust the support force at each support point, so that the smart mattress can dynamically adapt to the user's body changes and provide the user with a support effect that fits the human body curve.

[0129] Optionally, according to the pressure difference of the supporting point, the working state of the air pump connected to the first airbag unit corresponding to the supporting point and the working state of the air pump connected to the second airbag unit corresponding to the supporting point are controlled, and the working state of the air pump connected to the second airbag unit corresponding to the supporting point is also included: when the first airbag unit is deflated or inflated, the first valve corresponding to the first airbag unit is controlled to open; when the second airbag unit is deflated or inflated, the second valve corresponding to the second airbag unit is controlled to open.

[0130] The inflation and deflation assembly further includes a plurality of first valves and a plurality of second valves. A first valve is provided in the gas pipeline between the gas inlet of each first airbag unit and the gas outlet of the air pump connected thereto, and a second valve is provided in the gas pipeline between the gas inlet of each second airbag unit and the gas outlet of the air pump connected thereto. Specifically, when the first airbag unit is inflated or deflated by the air pump, the controller of the smart mattress controls the first valve to open; when the second airbag unit is inflated or deflated by the air pump, the controller of the smart mattress controls the second valve to open, so that an airflow path can be established between the air pump and the first airbag unit and between the air pump and the second airbag unit, thereby enabling the inflation or deflation operation of the first airbag unit and the second airbag unit. In addition, when the gas filling amount in the first airbag unit and the second airbag unit reaches the target value, that is, when the actual pressure at the supporting point corresponding to the first airbag unit and the second airbag unit reaches the target pressure, the controller of the smart mattress controls the first valve and the second valve to close to isolate the airflow path, thereby effectively preventing gas leakage or external pressure changes from affecting the pressure in the first airbag unit and the second airbag unit. Through the coordinated control of the first valve and the second valve, the gas filling amount in the first airbag unit and the second airbag unit can be accurately adjusted, and the air pressure of the first airbag unit and the second airbag unit can be ensured to be stable, thereby improving the accuracy and stability of the pressure adjustment of the smart mattress.

[0131] In addition, the first valve and the second valve may be solenoid valves, so that when the multiple first airbag units need to be inflated or deflated by an air pump, the opening and closing time of each first valve corresponding to each first airbag unit can be adjusted by the calculated pressure value that each first airbag unit needs to be adjusted, so as to accurately control the amount of gas entering or flowing out of each first airbag unit, thereby accurately controlling the gas filling amount of each first airbag unit. At the same time, when the multiple second airbag units need to be inflated or deflated by an air pump, the opening and closing time of each second valve corresponding to each second airbag unit can be adjusted by the calculated pressure value that each second airbag unit needs to be adjusted, so as to accurately control the amount of gas entering or flowing out of each second airbag unit, thereby accurately controlling the gas filling amount of each second airbag unit. By controlling the gas filling amount of each first airbag unit and each second airbag unit by the same air pump, the number of air pumps can be significantly reduced, thereby reducing hardware and design costs.
