The embodiment of the application discloses a mattress adjusting method, a mattress adjusting device, a mattress and a storage medium, which can adjust the real-time air pressure value of an air bag in a deformation area when the deformation area of the mattress is folded and deformed, so that the comfort of the mattress after the folding and deformation is improved. The following will describe in detail.
Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario of a mattress adjusting method according to an embodiment of the application. As shown in fig. 1, including a mattress 10, the mattress 10 may include a deformation region 110 and at least two support sections 120 disposed at intervals, the deformation region 110 being located between two adjacent support sections 120, the deformation region 110 connecting the two adjacent support sections 120. Wherein the deformation region comprises a balloon 130, and the balloon 130 is a sealed telescopic component capable of containing gas. The mattress 10 may include a flattened state and a folded state, and the support 120 may include a plurality of vertical elastic members, which may be springs. In the folded state, two adjacent supporting parts are connected in a bending way through a deformation area; in the flat state, the compression directions of the vertical elastic members included in the adjacent two supporting portions 120 are parallel to each other. The mattress 10 may detect the real-time air pressure value of the air cell 130 in the deformation region 110, determine the air pressure change rate of the air cell 130 according to the detected real-time air pressure value, and adjust the total amount of air in the air cell 130 if the air pressure change rate is greater than the preset rate threshold value, so that the real-time air pressure value of the air cell 130 reaches the preset air pressure value. The mattress 10 may further comprise an air valve for allowing the airtight air bag 130 to exchange air with the outside, that is, for discharging or inflating air, and an air pump for deflating or inflating the air bag 130.
Referring to fig. 2, fig. 2 is a flow chart of a mattress adjusting method according to an embodiment of the application. The method may be applied to the mattress 10 of fig. 1. As shown in fig. 2, the method may include the steps of:
210. and detecting the real-time air pressure value of the air bag, and determining the air pressure change rate of the air bag according to the real-time air pressure value.
In the embodiment of the application, the mattress can detect the real-time air pressure value of the air bags in each deformation area in real time, and particularly can detect the real-time air pressure value of the air bags through a sensor or equipment for air pressure detection. The mattress determines the air pressure change rate of the air bag according to the detected real-time air pressure value, specifically, the mattress detects the real-time air pressure value of the air bag at each moment in real time, and calculates the air pressure change rate of the air bag at two adjacent moments. For example, the time interval between two adjacent moments is 1 second, and the deformation action to be performed by the deformation region in the mattress may include a folding action and a flattening action. The folding action is to fold the deformation area, the air bag in the deformation area is compressed, and the volume of the air bag is relatively reduced because the air bag is a closed space, and the real-time air pressure value of the air bag in the deformation area can be continuously increased in the folding action process. The translation is to expand the deformation area, the air bag in the deformation area is expanded, and the volume of the air bag is relatively increased because the air bag is a closed space, and the real-time air pressure value of the air bag in the deformation area can be continuously reduced in the translation. Under the condition that the real-time air pressure value of the air bag continuously increases, the mattress detects that the real-time air pressure values of the air bag at three continuous moments t1, t2 and t3 are respectively 1 Pa, 2 Pa and 7 Pa, the difference between the real-time air pressure values of the adjacent two moments t1 and t2, t2 and t3 can be calculated to be respectively 1 Pa and 5 Pa, the difference is divided by the time interval between the adjacent two moments for 1 second, and the obtained values 1 Pa/second and 5 Pa/second can be respectively taken as the air pressure change rate at the moment t1 or the moment t2 or the air pressure change rate at the moment t2 and the moment t 3. Under the condition that the real-time air pressure value of the air bag continuously decreases, the mattress detects that the real-time air pressure value of the air bag at three continuous moments t4, t5 and t6 is respectively 10 Pa, 8 Pa and 3 Pa, the difference between the real-time air pressure values of the adjacent two moments t4 and t5, t5 and t6 is respectively 2 Pa and 5 Pa, the difference is divided by the time interval between the adjacent two moments for 1 second, and the obtained values of 2 Pa/second and 5 Pa/second can be respectively taken as the air pressure change rate at the moment t4 or the moment t5 or the air pressure change rate at the moment t5 and the moment t 6. Wherein, the air pressure change rate is not positive and negative, and is expressed as a positive number form.
In the embodiment of the application, the mattress can also detect the real-time air pressure value of the air bag at each moment in a plurality of time periods, and for any time period, the average value of the real-time air pressure values of the air bag at each moment in the time period is taken as the real-time air pressure value of the air bag at the time period, wherein the time lengths of the time periods are equal. After the real-time air pressure values of the air bags in two adjacent time periods are determined, the difference between the real-time air pressure values of the two adjacent time periods can be calculated, the difference is divided by the sum of the time lengths of the two adjacent time periods, and the obtained value can be used as the air pressure change rate of the previous time period or the next time period.
220. If the air pressure change rate is greater than the preset rate threshold, adjusting the total amount of air in the air bag so as to enable the real-time air pressure value of the air bag to reach the preset air pressure value.
In the embodiment of the application, after the air pressure change rate of the air bag is determined, the magnitude relation between the air pressure change rate and the preset rate threshold value can be compared. If the air pressure change rate is smaller than or equal to the preset rate threshold, for example, when a user lies on the mattress to turn over, the deformation area can be deformed slightly, the real-time air pressure value at the moment is changed slightly, and then the air pressure change rate is also reduced, so that the mattress does not need to adjust the total air quantity in the air bag. If the air pressure change rate is greater than the preset rate threshold, for example, when the deformation area on the mattress performs folding deformation, the deformation area will deform greatly, and the real-time air pressure value at the moment changes greatly, so that the air pressure change rate is also greater, and the mattress needs to adjust the total amount of air in the air bag. Referring specifically to fig. 3, fig. 3 is a schematic structural view of an airbag adjustment device in a mattress according to an embodiment of the present disclosure. As shown in fig. 3, a mattress control module may be included in the mattress, and a pneumatic detector, a pneumatic pump, and a pneumatic valve may be included in the mattress control module. The mattress detects the real-time air pressure value of the air bag included in the deformation area through the air pressure detector, and after the air pressure change rate is determined to be greater than the preset rate threshold according to the detected real-time air pressure value, the mattress control module can control one or more air valves on the air bag to be opened, and control the air pump to adjust the total air quantity in the air bag through the opened air valve on the air bag, so that the real-time air pressure value of the air bag is changed, and the preset air pressure value is achieved. The mattress may in particular be adapted to the total amount of air in the air cells in connection with the rate of change of air pressure and the deformation action to be performed by the deformation zone. For example, the deformation action to be performed by the deformation region may include a folding action and a flattening action. The folding action is to fold the deformation area, the air bag included in the deformation area is compressed, and the volume of the air bag is relatively reduced because the air bag is a closed space, the real-time air pressure value of the air bag included in the deformation area after the folding action is executed is increased, at the moment, if the determined air pressure change rate is greater than the preset rate threshold, the mattress needs to open an air valve on the air bag, and the air pump is controlled to deflate the air bag, so that the total air quantity in the air bag is reduced, and the real-time air pressure value of the air bag reaches the preset air pressure value. The translation operation is to expand the deformation region, the air bag included in the deformation region is expanded, the volume of the air bag is increased because the air bag is a closed space, the real-time air pressure value of the air bag included in the deformation region after the folding operation is performed is relatively increased, at this time, if the determined air pressure change rate is greater than the preset rate threshold, the mattress needs to open an air valve on the air bag and control the air pump to perform the air inflation operation on the air bag, so as to increase the total amount of air in the air bag, and enable the real-time air pressure value of the air bag to reach the preset air pressure value. The preset speed threshold and the preset air pressure value can be set by a user.
In one embodiment, if the air pressure change rate is greater than the preset rate threshold in the execution step 220, the mattress may further include the following steps in the process of adjusting the total amount of air in the air bag so that the real-time air pressure value of the air bag reaches the preset air pressure value:
if the real-time air pressure value of the air bag is increased and the air pressure change rate is larger than the preset rate threshold, reducing the total amount of air in the air bag according to the preset air release rate so as to reduce the real-time air pressure value of the air bag to the preset air pressure value;
if the real-time air pressure value of the air bag is reduced and the air pressure change rate is larger than the preset rate threshold, the total amount of air in the air bag is increased according to the preset inflation rate, so that the real-time air pressure value of the air bag is increased to the preset air pressure value.
In the embodiment of the application, after the air pressure change rate of each moment is determined according to the real-time air pressure value of the air bag at each moment, the mattress judges the magnitude relation between the air pressure change rate of each moment and the preset speed threshold. If the air pressure change rate at a moment is greater than the preset rate threshold, the mattress also needs to judge whether the real-time air pressure value of the air bag at the moment is increased or decreased. If the real-time air pressure value at the moment is larger than the real-time air pressure value at the previous moment, judging that the real-time air pressure value of the air bag at the moment is increased; similarly, if the real-time air pressure value at that time is less than or equal to the real-time air pressure value at the previous time, it can be determined that the real-time air pressure value of the air bag at that time is decreasing.
Therefore, if the real-time air pressure value of the air bag increases and the air pressure change rate at that time is greater than the preset rate threshold, then the deformed region of the mattress may be considered to be folding such that the volume of the air bag in the deformed region is reduced. The mattress can comprise a mattress control module, and the mattress control module can comprise an air pressure detector, an air pump and an air valve. At this time, the mattress control module can control one or more air valves on the air bag to be opened, and control the air pump according to the preset deflation rate, and the air pump adjusts the total amount of air in the air bag through the air valve opened on the air bag, so that the total amount of air in the air bag is reduced from the moment, and the real-time air pressure value of the air bag is gradually reduced. In the process of gradually reducing the real-time air pressure value of the air bag by deflating the air bag according to the preset deflating rate, the mattress continuously detects the real-time air pressure value of the air bag, and when the real-time air pressure value of the air bag is smaller than or equal to the preset air pressure value, the mattress can stop reducing the total air quantity in the air bag, so that the real-time air pressure value of the air bag is reduced to the preset air pressure value.
If the real-time air pressure value of the air bag is reduced and the air pressure change rate at the moment is greater than the preset rate threshold value, the deformation area of the mattress can be considered to be flattened, so that the volume of the air bag of the deformation area is increased. At this time, the mattress control module can control one or more air valves on the air bag to be opened, and control the air pump according to the preset inflation rate, and the air pump adjusts the total amount of air in the air bag through the air valve opened on the air bag, so that the total amount of air in the air bag is increased from the moment, and the real-time air pressure value of the air bag is gradually increased. In the process of inflating the air bag according to the preset inflation rate to gradually increase the real-time air pressure value of the air bag, the mattress continuously detects the real-time air pressure value of the air bag, and when the real-time air pressure value of the air bag is greater than or equal to the preset air pressure value, the mattress can stop increasing the total air quantity in the air bag, so that the real-time air pressure value of the air bag is increased to the preset air pressure value. Wherein the preset deflation rate and the preset inflation rate are settable by a user.
In the embodiment of the application, when the air bag is required to be deflated or inflated to reduce or increase the real-time air pressure value of the air bag, the deflation or inflation operation is performed by the preset deflation rate or the preset inflation rate, so that the process of deflating or inflating the air bag to reduce or increase the real-time air pressure value of the air bag is predictable, the control is better, and if the preset deflation rate or the preset inflation rate is smaller, the real-time air pressure value of the air bag after the total air quantity is adjusted is more approximate to the preset air pressure value, and the comfort of the mattress is further improved.
By adopting the embodiment, the real-time air pressure value of the air bag can meet the preset air pressure value, and when the deformation area of the mattress is folded and deformed, for example, the mattress is folded or the mattress is laid flat, the real-time air pressure value of the air bag in the deformation area is adjusted, so that the air pressure of the air bag is prevented from being too high or too low, and the comfort of the mattress after the folding and deformation is improved.
In one embodiment, referring to fig. 4, fig. 4 is a flow chart of another mattress adjusting method according to an embodiment of the application. The method may be applied to the mattress 10 of fig. 1. As shown in fig. 4, the method may include the steps of:
410. And detecting the real-time air pressure value of the air bag, and determining the air pressure change rate of the air bag according to the real-time air pressure value.
In the embodiment of the application, the mattress judges the magnitude relation between the air pressure change rate and the preset rate threshold after determining the air pressure change rate of the air bag according to the detected real-time air pressure value of the air bag and according to the real-time air pressure value, and meanwhile, the mattress also judges the change trend of the real-time air pressure value of the air bag, and the change trend is embodied in whether the real-time air pressure value of the air bag is increased or decreased.
In the embodiment of the present application, if the real-time air pressure value of the air bag increases and the air pressure change rate is greater than the preset rate threshold, step 420 is executed; if the real-time air pressure value of the air bag is reduced and the air pressure change rate is greater than the preset rate threshold, step 440 is performed.
420. If the real-time air pressure value of the air bag is increased and the air pressure change rate is larger than the preset rate threshold, the total amount of air in the air bag is reduced so as to reduce the real-time air pressure value of the air bag.
In embodiments of the present application, the mattress may be provided for a fixed length of time. When the mattress detects the real-time air pressure value of the air bag, the first moment is taken as the initial moment, after a set fixed time length is passed, the mattress can count the number of moments when the real-time air pressure value is increased in the time length, wherein for any moment, if the real-time air pressure value of the moment is larger than the real-time air pressure value of the last moment, the real-time air pressure value of the moment is considered to be increased. If the number of times the real-time air pressure value increases in the time period is 80% of the preset ratio, for example, it is considered that the trend of the change in the real-time air pressure value of the air bag at each time in the time period is increased.
When the mattress detects that the real-time air pressure value of the air bag is increased at a moment, and the air pressure change rate at the moment is larger than the preset rate threshold, the deformation area of the mattress can be considered to be folded, so that the volume of the air bag in the deformation area is reduced, the real-time air pressure value is increased, the air pressure change rate is increased, the mattress can start to open the air valve at the moment, and the air pump is adopted to deflate the air bag, so that the total air quantity in the air bag is reduced, and the real-time air pressure value of the air bag is gradually reduced.

In embodiments of the present application, the mattress may detect whether each deformation zone on the mattress has deformed, which may include the deformation zone folding or the deformation zone flattening. The distance between two adjacent supporting parts of each deformation area can be detected by the distance detection equipment, and if the distance is changed or the distance change amplitude is larger than a set threshold value, the mattress can be considered to deform the deformation area corresponding to the distance, and the mattress can be folded or flattened. At this time, the mattress can detect the included angle between two adjacent supporting parts of the deformed region, and determine the deformation parameters of the deformed region by comparing the included angles of the two supporting parts before the deformed region is deformed.

640. If the deformation parameter is smaller than 0 and the air pressure change rate is larger than the preset rate threshold, the total amount of air in the air bag is increased, so that the real-time air pressure value of the air bag reaches the preset air pressure value.
