[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0054] The components of the embodiments of the present application generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but rather merely represents selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0055] Hereinafter, the terms "including", "having" and their cognates, which may be used in various embodiments of the present application, are intended only to indicate specific features, numbers, steps, operations, elements, components or combinations of the foregoing items, and should not be understood as first excluding the existence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing items or the possibility of adding one or more features, numbers, steps, operations, elements, components or combinations of the foregoing items.

[0056] Furthermore, the terms “first,” “second,” “third,” etc., are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0057] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which the various embodiments of the present application belong. Terms (such as those defined in generally used dictionaries) will be interpreted as having the same meaning as in the context of the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present application.

[0058] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0059] Often, users experience excessive pressure on certain areas due to incorrect sleeping posture or issues with the bed material, which can increase the risk of pressure sores. Furthermore, due to the fixed nature of each bed material, most users struggle to achieve satisfactory sleep comfort.

[0060] Therefore, in order to solve the above problems, the present application proposes a posture adjustment method.

[0061] Please refer to Figure 1, which is a flowchart of a posture adjustment method proposed in an embodiment of the present application. Exemplarily, the posture adjustment method is applied to a posture adjustment device, such as a posture adjustment air cushion, a posture adjustment sofa, etc.

[0062] In some embodiments, as shown in FIG1 , the posture adjustment method is applied to a posture adjustment device, the posture adjustment device including a pressure sensor and a plurality of regional airbags, and the method includes:

[0063] S110 , collecting point pressure parameters of each pressure matrix point where the user presses on the posture adjustment device.

[0064] Specifically, when the user presses on the posture adjustment device, each pressure matrix point in the device is pressed, so that each pressure matrix point generates a corresponding pressure parameter, wherein the pressure parameter includes the pressure value and the point position of the pressure matrix point.

[0065] In the posture adjustment method of some embodiments, as shown in FIG. 2 , the pressure sensor includes a longitudinal conductive layer 110 , a piezoresistive layer 120 , and a transverse conductive layer 130 .

[0066] The vertical conductive layer 110 includes a plurality of parallel, spaced longitudinal conductive strips; the transverse conductive layer 130 includes a plurality of parallel, spaced transverse conductive strips. The piezoresistive layer 120 is disposed between the vertical conductive layer 110 and the transverse conductive layer 130, so that the plurality of longitudinal conductive strips, the plurality of transverse conductive strips, and the piezoresistive layer 120 form a pressure matrix. The vertical conductive layer 110 connects to the transverse conductive layer 130 via the pressure matrix points, forming a conductive loop.

[0067] Specifically, when the longitudinal conductive layer 110, the piezoresistive layer 120, and the transverse conductive layer 130 are sequentially overlapped, a "conductive grid" similar to a chessboard grid is formed due to the different directions of the conductive strips in the longitudinal conductive layer 110 and the transverse conductive layer 130. However, since a layer of compression layer is provided in the transverse conductive layer 130 and the longitudinal conductive layer 110, the overlapping portion of the transverse conductive layer 130 and the longitudinal conductive layer 110 is not directly conductive, but the overlapping portion of one of the transverse conductive layer 130 and the longitudinal conductive layer 110 is connected to the overlapping portion of the other conductive layer through the overlapping portion of the compression layer to form a loop. Among them, the overlapping portion of the compression layer, the overlapping portion of the longitudinal conductive layer 110, and the overlapping portion of the transverse conductive layer 130 overlap. Among them, the overlapping portion of each compression layer is regarded as a point, that is, a matrix pressure point. For example, as shown in FIG3, the overlapping portion is the portion where two mutually perpendicular lines intersect and overlap.

[0068] The pressure sensor is set on an airbag cushion composed of several regional airbags. When the regional airbags are inflated and deflated, they drive the local pressure sensors at the corresponding positions to move, so as to adjust the pressure between the local pressure sensors and the user's body.

[0069] Specifically, the user presses on one side of the pressure sensor, while the airbag cushion is on the other side, placing the pressure sensor between the user and the cushion. When the user presses on the pressure sensor, they also press on the cushion. When the cushion inflates and deflates, this causes the pressure sensor to move, which in turn causes the user to move. Because the cushion doesn't inflate or deflate as a whole, but rather each regional airbag can inflate and deflate independently, inflation and deflation of a regional airbag only causes movement of the corresponding pressure sensor, and thus of the corresponding part of the user's body, thereby adjusting the user's posture.

[0070] Alternatively, the shape of the surface where each regional airbag (i.e., the smallest unit) contacts the pressure sensor can be the same as a closed figure formed by one or more matrix pressure points. For example, as shown in FIG3 , if the closed figure formed by the matrix pressure points is a rectangle, then it is a rectangle of the first pattern in the figure. The closed figure formed by the matrix pressure points is a rectangle of the first pattern. The shape of the surface where each regional airbag contacts the pressure sensor can be the same as a closed figure formed by one matrix pressure point (i.e., the first pattern), a closed figure formed by three matrix pressure points (i.e., the third pattern), a closed figure formed by four matrix pressure points (i.e., the second pattern), and so on, without limitation.

[0071] S210 , determining the position of a body part of the user and an average pressure value corresponding to the body part position according to the pressure parameter of each point.

[0072] Specifically, because the entire posture adjustment device is relatively large, the location of the pressure applied each time the user presses on it is not fixed. As shown in Figure 4, only the area pressed down is a darker color, and the greater the pressure, the darker the color, while the lighter the pressure, the lighter the color. Therefore, each time, the user's current body part position and the average pressure value corresponding to the body part position must be determined based on the obtained pressure parameters to facilitate subsequent calculations. The body part position refers to the current position of the body part within the posture adjustment device.

[0073] In some embodiments of the posture adjustment method, the pressure parameters include pressure values ​​and point positions of pressure matrix points. Determining the position of a user's body part and the average pressure value corresponding to the body part position based on each point pressure parameter includes:

[0074] The pressure matrix points having pressure values ​​not less than the screening threshold are screened out to determine the positions of the user's body parts.

[0075] Specifically, when the user presses on the posture adjustment device, the pressure value of the pressure matrix point corresponding to the part pressed by the user's body is non-zero, which serves as the basis for determining the location of the user's body part. However, when the sensor is placed on a bed or sofa, there may be wrinkles or additional pressure from accessories (such as sheets and cushions) that cause the pressure value to be greater than 0. In this case, the pressure matrix point with a pressure value greater than 0 may not be the user's body part. Therefore, it is necessary to set a screening threshold to further accurately screen the user's body part location.

[0076] The average pressure value of all pressure matrix points whose pressure values ​​are not less than the screening threshold is calculated as the average pressure value corresponding to the body part position.

[0077] Exemplarily, if the pressure values ​​corresponding to all pressure matrix points whose pressure values ​​are not less than the screening threshold are a, b, c and d respectively, then the average pressure value is Y=(a+b+c+d) / 4, and the average pressure value corresponding to the body part position is Y.

[0078] S310, determining target area airbags according to the position of the user's body parts.

[0079] Specifically, since the posture adjustment device contains a large number of regional airbags, in order to accurately adjust the user's posture based on the user's current posture, it is necessary to determine the target regional airbags to accurately adjust the user's posture, rather than adjusting each regional airbag. The target regional airbag is the regional airbag that presses on the user's body part.

[0080] Furthermore, the target area airbag is determined based on the pressure parameters of the pressure matrix points. Since the pressure matrix points and the target area airbag are not the same object, and the target area airbag is located on one side of the pressure sensor, it is also necessary to determine the target area airbag based on the pressure parameters of the pressure matrix points. In other words, the target area airbag at the corresponding position is found based on the point position of the pressure matrix point. Each area airbag corresponds to at least one pressure matrix point.

[0081] S410, adjusting the air pressure of the airbag in the target area according to the average pressure value to adjust the posture of the corresponding body part.

[0082] In some embodiments of the posture adjustment method, as shown in FIG5 , each regional airbag corresponds to a plurality of pressure matrix points; based on the average pressure value, the target regional airbag is adjusted to adjust the corresponding body part, including:

[0083] S411, obtaining the target pressure parameter of each pressure matrix point corresponding to the airbag in each target area.

[0084] S412: Calculate the average airbag pressure of each target area airbag according to the target pressure parameter.

[0085] Specifically, first determine all area airbags pressed by the user, that is, determine each target area airbag. Since each target area airbag corresponds to at least one pressure matrix point, the pressure values ​​of all pressure matrix points corresponding to each target area airbag can be obtained. The pressure values ​​of all pressure matrix points corresponding to each target area airbag are averaged to obtain the average airbag pressure.

[0086] Exemplarily, if an airbag in a target area corresponds to three pressure matrix points, and the pressure values ​​corresponding to the three pressure matrix points are m, n, and q, respectively, then the average airbag pressure is the average of m, n, and q, that is, (m+n+q) / 3.

[0087] S413: Calculate an upper average pressure threshold and a lower average pressure threshold according to the average pressure value.

[0088] Specifically, due to different physiques, some people are heavier and some are lighter. Therefore, the final calculated average pressure value will also be different, and the corresponding average pressure threshold will be different. In order to ensure that the appropriate adjustment is made for each person, the average pressure threshold adopted should also vary according to the individual situation of the user. The average pressure threshold includes an upper average pressure threshold and a lower average pressure threshold.

[0089] Optionally, the average pressure threshold is calculated according to a preset multiple of the average pressure value. For example, the preset upper multiple of the upper average pressure threshold is 1.2, and the preset lower multiple of the lower average pressure threshold is 0.8. When the average pressure value is 100, the upper average pressure threshold is 120, and the lower average pressure threshold is 80. Of course, the preset multiples here can be adjusted arbitrarily according to different application scenarios and are not limited here.

[0090] S414: When the average airbag pressure is greater than the upper average pressure threshold, the airbag in the corresponding target area is controlled to be exhausted.

[0091] S415 , when the average airbag pressure is not greater than the lower average pressure threshold, controlling the inflation of the airbag in the corresponding target area.

[0092] Specifically, when a user presses the posture adjustment device, different postures will cause different pressure values ​​at the pressure matrix points corresponding to each body part. Under normal circumstances (the most comfortable situation), the average pressure value of each target area airbag pressed by the user will not be too high. Therefore, when the average airbag pressure of a target area airbag is too high, it means that the pressure value exerted by the airbag in this target area on the user is too high, and the airbag in this target area needs to be deflated to reduce the pressure. Conversely, when the average airbag pressure of a target area airbag is too low, it means that the pressure value exerted by the airbag in this target area on the user is too low, and the airbag in this target area needs to be inflated.

[0093] Exemplarily, if the target area airbags include airbag average pressure values ​​of 90, 100, 120, and 130, and the average pressure value is 110, the upper average pressure threshold is 120, and the lower average pressure threshold is 100, then the target area airbag with a pressure value of 90 needs to be inflated, and the target area airbag with a pressure value of 130 needs to be deflated.

[0094] Optionally, the target area airbags whose average airbag pressure is greater than the upper average pressure threshold or not greater than the lower average pressure threshold may be inflated and deflated until the corresponding average airbag pressure reaches the average pressure value.

[0095] In some embodiments of the posture adjustment method, before determining the position of the user's body part and the average pressure value corresponding to the body part position based on each point pressure parameter, the method further includes:

[0096] The working mode of the posture adjustment device is determined based on the point pressure parameter of each pressure matrix point.

[0097] When the working mode of the posture adjustment device is the posture adjustment mode, the position of the user's body part and the average pressure value corresponding to the body part position are determined according to the pressure parameter of each point.

[0098] Specifically, the object pressing on the posture adjustment device is not necessarily a person, but may be an object, etc. Therefore, only when it is determined that the object meets the characteristics of a person will the posture adjustment working mode be entered. After entering the posture adjustment mode, the above-mentioned posture adjustment steps will be performed.

[0099] In some embodiments of the posture adjustment method, the pressure parameters include the point position and pressure value of the pressure matrix point, and judging the state of the posture adjustment device based on the point pressure parameter of each pressure matrix point includes:

[0100] Based on the average pressure of each airbag, the user's breathing rate is calculated.

[0101] Based on the breathing rate, determine whether the current state is posture adjustment mode.

[0102] Specifically, since the easiest and most intuitive distinguishing feature between people and objects is breathing, the user's breathing rate is calculated based on the average pressure of each airbag.

[0103] In some embodiments of the posture adjustment method, calculating the respiratory rate based on the average pressure of each air bag includes:

[0104] Calculate the standard deviation of the average airbag pressure of each area within a preset time period.

[0105] Find the maximum standard deviation value among each standard deviation value.

[0106] Obtain the average pressure of each target airbag in the area airbag corresponding to the maximum standard deviation value within a preset time period.

[0107] Specifically, when the user presses on the posture adjustment device to breathe, the degree of fluctuation of each part of the body is different. The closer to the upper body (chest, stomach), the greater the degree of fluctuation. Therefore, it is necessary to find the part of the body with the largest degree of fluctuation to calculate the respiratory rate in the most accurate way. When the body fluctuates, the pressure value of the corresponding pressure matrix point pressed on the posture adjustment device changes accordingly, and the average airbag pressure of the corresponding regional airbag changes accordingly. Therefore, the corresponding user's breathing rate can be calculated based on the degree of change of the average airbag pressure of each airbag. The standard deviation value of the average airbag pressure of each airbag at continuous and different times is calculated. When the standard deviation value is larger, it means that the corresponding airbag has a larger degree of fluctuation, and it can better represent the user's breathing changes. Among them, the target airbag pressure average value refers to the average airbag pressure of the regional airbag corresponding to the maximum standard deviation value within a preset time period.

[0108] Based on the average of each target cuff pressure, the user's breathing rate is calculated.

[0109] Specifically, the user's breathing rate is calculated based on the change in the average value of each target airbag pressure within a preset time period. The preset time period can range from 5 to 40 seconds, and other ranges are also possible. This is not a limitation and can be determined based on specific circumstances.

[0110] Furthermore, a breathing curve is obtained based on the average value of each target airbag pressure, where the abscissa of the curve is time and the ordinate is the average value of the target airbag pressure. The breathing rate is calculated based on the spacing between each peak point in the breathing curve.

[0111] For example, if the 5th, 15th, and 26th data are peak points, the interval between each breath is 10 and 11 data points, and the average of the interval time is 10.5, and if the interval between each data sample is 0.5s, then 10.5 data points is equivalent to one breath in 5.25 seconds, and the breathing rate is 5.25s / time.

[0112] Alternatively, if a respiratory rate is detected first and then the breathing disappears when there is no obvious change in pressure, it is determined to be apnea, and an early warning signal is generated and recorded, or the early warning signal is transmitted to a monitoring room.

[0113] The embodiments of the present application propose a posture adjustment method, which is applied to a posture adjustment device. The posture adjustment device includes a pressure sensor and several regional airbags. The method collects the point pressure parameters of each pressure matrix point where the user presses on the posture adjustment device; determines the user's body part position and the average pressure value corresponding to the body part position based on each point pressure parameter; then determines the target regional airbag based on the user's body part position; and finally, adjusts the air pressure of the target regional airbag based on the average pressure value to adjust the posture of the corresponding body part. The present application determines the user's pressure condition by detecting the pressure parameters of each position where the user presses on the pressure sensor, thereby adjusting the user's posture, reducing the risk of pressure sores, and improving the user's comfort.

[0114] Another embodiment of the present application further provides a posture adjustment system 500, as shown in FIG6 , which is applied to a posture adjustment device. The posture adjustment device includes a pressure sensor and a plurality of regional airbags. The system 500 includes:

[0115] The collecting unit 510 is used to collect the point pressure parameters of each pressure matrix point pressed by the user on the posture adjustment device.

[0116] The first determining unit 520 is configured to determine the position of a body part of the user and an average pressure value corresponding to the body part position according to the pressure parameter of each point.

[0117] The second determining unit 530 is configured to determine the target area airbag according to the position of the user's body part.

[0118] The adjustment unit 540 is used to adjust the air pressure of the airbag in the target area according to each average pressure value to adjust the posture of the corresponding body part.
