In the present invention, the first structural layer 211 and the second structural layer 212 are made of rigid plastic sheet, but other materials, such as light alloy, may be used.
In the present invention, the pressure sensing element 214 is a pressure sensor or a pressure sensor, the shearing force sensing element 213 is composed of two capacitive electrode plates arranged in parallel and a deformable dielectric body arranged between the two electrode plates, the principle that the overlap amount of the two electrode plates is changed according to the shearing force so as to change the output capacitance is adopted, and the control module 3 measures the output capacitance value of the shearing force sensing element, so as to obtain the shearing force value.
In the invention, the vertical adjusting piece 215 is an electric push rod, an air cylinder or a hydraulic cylinder, and can be selectively used according to the requirement.
In some embodiments of the present invention, the transverse adjusting component 216 may be adjusted only along the position in the fixed linear direction, and at this time, the transverse adjusting component 216 may be configured by using a motor, a screw rod, and a moving block, and this embodiment is suitable for some scenes where only a shear force in the fixed direction exists, such as a back cushion for a ward, and the shear force generally occurs along the direction from the back to the hip, and at this time, only the transverse adjusting component 216 needs to have the position adjustment in this direction.

When the horizontal position is required to be adjusted, the electric rotating disc 2162 is controlled to rotate firstly, so that the direction of the horizontal slide rail 2163 is consistent with the direction of the shearing force, then the electric telescopic rod 2165 is controlled to perform telescopic driving, the mounting table 2164 is driven to move along the horizontal slide rail 2163, and the adjustment of the supporting position of the supporting unit 21 is realized in the moving process. This embodiment is suitable for some scenarios where there are shear forces in different directions, such as a mattress. Of course, in this embodiment, it is necessary to acquire the direction information of the shearing force, and therefore, a shearing force sensor with direction recognition is adopted, or a direction recognition function is added to the shearing force sensing element 213, for example, a displacement sensor, a distance sensor, etc. is provided to monitor the relative displacement direction of the two electrode plates, and the monitoring signal of the sensor is also transmitted to the control module 3 for analysis processing, so as to acquire the direction information of the shearing force.

the storage unit 32 is used for storing the shearing force value and the standard value corresponding to the pressure value;
the processing unit 33 is configured to compare the obtained shear force value and the obtained pressure value with the stored corresponding standard values, and when the shear force value in a certain supporting unit 21 is greater than the standard value, use the supporting unit 21 as the center and select the surrounding supporting unit 21 that diverges outward, control the horizontal adjusting member 216 of the central supporting unit 21 and the surrounding supporting unit 21 to perform horizontal position adjustment, and when the pressure value in a certain supporting unit 21 is greater than the standard value, use the supporting unit 21 as the center and select the surrounding supporting unit 21 that diverges outward, control the vertical adjusting member 215 of the central supporting unit 21 and the surrounding supporting unit 21 to perform vertical height adjustment.
Wherein, the horizontal position is adjusted specifically to be: controlling the lateral adjusting members 216 of the central supporting unit 21 and the peripheral supporting unit 21 to move towards the shearing force direction, wherein the moving distance of the central supporting unit 21 is the largest and is determined by the magnitude of the shearing force value larger than the standard value, and the moving distance of the peripheral supporting unit 21 along the diverging direction is gradually reduced to zero; the vertical height adjustment is specifically as follows: the vertical adjustment pieces 215 controlling the central support unit 21 and the peripheral support unit 21 are contracted downward, wherein the contraction distance of the central support unit 21 is the largest and is determined by the magnitude that the pressure value is greater than the standard value, and the contraction distance of the peripheral support unit 21 is gradually reduced to zero along the divergent direction.
The control module 3 is preset with a corresponding relation between a pressure value and a vertical adjustment amount and a corresponding relation between a shearing force value and a horizontal adjustment amount, and different adjustment amounts are controlled according to the corresponding relations under different conditions. Taking a pressure value as an example, for example, the pressure value in a certain supporting unit 21 is 40mmHg and exceeds a standard value of 30mmHg, at this time, the vertical adjusting members 215 in the supporting unit 21 are controlled to contract downward by 1cm, the vertical adjusting members 215 in a circle of the supporting units 21 around the supporting unit 21 are controlled to contract downward by 0.8cm, the vertical adjusting members 215 in the outer circle of the supporting units 21 contract downward by 0.6cm, and so on until the contraction distance is zero. By adopting the adjusting mode, the vertical pressure of the body can be maximally distributed, the pressure intensity is reduced, and meanwhile, the position with overlarge height difference after adjustment is avoided, so that the shearing force caused by adjustment is avoided. For another example, the pressure value in a certain supporting unit 21 is 50mmHg, and the magnitude larger than the standard value is increased, so that the vertical adjusting member 215 in the supporting unit 21 can be controlled to contract and move 1.5cm downwards, while the contraction distance of the surrounding supporting units 21 is still gradually reduced to zero.
In the invention, the early warning module 4 further: the early warning module 4 is internally provided with a timing function, timing is started when the shear force value or the pressure value is not less than a standard value after the transverse position adjustment and/or the vertical height adjustment, and alarm information is sent when the timing duration exceeds the set duration, for example, the set duration is 5min, namely after 5min, if the shear force value or the pressure value is not less than the standard value, the alarm information is sent.
