Description

Technical Field

[0001] This application relates to the field of smart furniture technology, and in particular to an adjustable support structure, a sofa, and a method for adjusting the support shape. Background Technology

[0002] Traditional sofas typically use fixed-structure fillings such as foam and springs, and their support shape cannot be changed once manufactured. Since different users have different heights, weights, and sitting habits, a fixed support curve cannot meet the comfort needs of everyone at the same time. This may lead to problems such as some users' lower backs being unsupported and uneven pressure distribution on their buttocks. Sitting for a long time can easily cause fatigue and even lead to lumbar discomfort.

[0003] Currently, for adjustable sofas, such as those equipped with inflatable bladders, most adjustments require manual operation by the user, and the adjustment precision is limited, resulting in insufficient fitting accuracy to the human body curve and low adjustment accuracy. Summary of the Invention

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0056] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0058] In one exemplary embodiment, a sofa is provided, including a support-adjustable structure.

[0059] In one exemplary embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is one of the structural diagrams for a support structure with adjustable shape. Figure 2 and Figure 3These are two exploded view diagrams of an adjustable support structure. An adjustable support structure is provided, comprising: a support mechanism 100, a sensing mechanism 200, an adjustment mechanism 300, and a control mechanism 400. The support mechanism 100 includes at least one support component, each having a support surface for supporting a support area of ​​a target object; different support components are used to support different support areas of the target object. The sensing mechanism 200 includes the same number of sensing components as the support components, located inside the support components and on the side of the support surface away from the target object; the sensing components are used to collect pressure signals from the support area. The adjustment mechanism 300 includes the same number of adjustment components as the sensing components, located inside the support components and on the side of the sensing components away from the target object. The control mechanism 400 is connected to both the sensing mechanism 200 and the adjustment mechanism 300, and is used to adjust the support shape of the adjustment components according to the pressure signals collected by the sensing components.

[0060] In this system, the sensing components of the sensing mechanism 200 correspond one-to-one with the support components of the support mechanism 100 and are embedded on the back side of the support surface. When the target object comes into contact with the support surface, different support areas will generate differentiated pressures, which are transmitted to the corresponding sensing components through the support components. The sensing components convert the mechanical signals into electrical signals and transmit them to the control mechanism 400. The control mechanism 400, as the core processing unit, pre-stores pressure thresholds or ideal pressure distribution models. After receiving the pressure signals from each sensing component, it compares and analyzes the deviation between the current pressure distribution and the ideal model: if the pressure in a certain support area is too high, it determines that the support stiffness in that area is too large; if the pressure is too low, it determines that the support stiffness is too small. Based on the deviation analysis results, the control mechanism 400 outputs adjustment commands to the adjustment components at the corresponding positions.

[0061] The adjustment component of the adjustment mechanism 300 is located on one side of the sensing component, forming a three-layer nested structure of "support surface - sensing layer - adjustment layer" with the support component. After receiving control commands, the adjustment component adjusts the support shape through the deformation of its own mechanical structure. Common mechanical adjustment methods include rigid adjustment and flexible adjustment. Taking flexible adjustment as an example, the adjustment component can have a built-in air chamber. By inflating and deflating the chamber, the pressure is adjusted, indirectly changing the support stiffness of the support component. The adjusted support component will generate a new pressure signal again, which is fed back to the control mechanism 400 until the pressure distribution conforms to the ideal model, forming a closed-loop adjustment.

[0062] In this embodiment, the support shape of each support area can be adjusted in real time according to the different outlines of different target objects or the pressure distribution changes in different scenarios, which improves the accuracy of support shape adjustment, maximizes the contact area between the support surface and the target object, avoids local suspension or stress concentration, and improves support stability.

[0063] In one exemplary embodiment, such as Figure 4 and Figure 5 As shown, Figure 4 The second structural diagram for supporting the adjustable structure. Figure 5 This is the third schematic diagram of the adjustable support structure. The support mechanism 100 includes a first support component 110 and a second support component 120. The first support component 110 is disposed along a first direction X1 and has a first support surface for supporting a first support region S1 of a target object. The second support component 120 is disposed along a second direction X2 and has a second support surface for supporting a second support region S2 of the target object. The first direction X1 and the second direction X2 intersect.

[0064] The sensing mechanism 200 includes a first sensing component 210 and a second sensing component 220. The first sensing component 210 is located inside the first support component 110 and on the side of the first support surface furthest from the target object. The first sensing component 210 is located within a first sensing region L1 corresponding to the first support region S1 and is used to collect a first pressure signal from the first support region S1. The second sensing component 220 is located inside the second support component 120 and on the side of the second support surface furthest from the target object. The second sensing component 220 is located within a second sensing region L2 corresponding to the second support region S2 and is used to collect a second pressure signal from the second support region S2. It should be noted that the sensing mechanism 200 is constructed using a flexible fabric pressure sensor array, combining pressure sensing functionality with a flexible fabric substrate. It can be directly embedded into the back side of the support surface of the support component, bending synchronously with the deformation of the support component. Its rigidity does not affect the comfort or adjustment accuracy of the support surface, and it fits tightly against the adjustment mechanism 300.

[0065] The adjustment mechanism 300 includes a first adjustment component 310 and a second adjustment component 320. The first adjustment component 310 is disposed inside the first support component 110 and located on the side of the first sensing component 210 furthest from the target object; the second adjustment component 320 is disposed inside the second support component 120 and located on the side of the second sensing component 220 furthest from the target object. It is understood that... Figure 4 In the first sensing component 210, the first adjusting component 310 is attached to the surface of the first adjusting component 310 that is close to the target object, and the second sensing component 220 is attached to the surface of the second adjusting component 320 that is close to the target object.

[0066] The control mechanism 400 is used to adjust the support shape of the first adjustment component 310 according to the first pressure signal collected by the first sensing component 210, and to adjust the support shape of the second adjustment component 320 according to the second pressure signal collected by the second sensing component 220.

[0067] The first support component 110 is arranged along the first direction X1, covering the first support area S1 of the target object (such as the longitudinal area of ​​the human back); the second support component 120 is arranged along the second direction X2, covering the second support area S2 of the target object (such as the transverse area of ​​the human back). Since X1 and X2 intersect, the support surfaces of the two support components form a grid-like superimposed coverage area, enabling fine-grained zoning of the support parts of the target object. The first sensing component 210 is embedded on the back side of the support surface of the first support component 110 and is confined within the first sensing area L1, collecting pressure signals only at each support point along the first direction X1; the second sensing component 220 is embedded on the back side of the support surface of the second support component 120 and is confined within the second sensing area L2, collecting pressure signals only at each support point along the second direction X2. The control mechanism 400 can simultaneously acquire two-dimensional pressure distribution data to accurately locate specific areas with excessively high / low pressure.

[0068] In this system, after analyzing the first pressure signal, the control mechanism 400 outputs a command to the first adjustment component 310 to change the stiffness of the support component in the first direction X1 through methods such as inflation adjustment. Similarly, based on the second pressure signal, the second adjustment component 320 is adjusted to change the shape of the support component in the second direction X2. The actions of the two adjustment components are executed independently, enabling coordinated control of the intersecting area. The adjusted support component generates a new pressure signal, which is fed back to the control mechanism 400 by the sensing component. The control mechanism 400 compares the deviation between the current two-dimensional pressure distribution and the ideal model, and readjusts the support shape until the pressure distribution of the entire support surface reaches the optimal state.

[0069] In this embodiment, the two-dimensional grid division of the support area is achieved by arranging the two directions intersecting. Pressure acquisition and shape adjustment are not limited to a single direction, and can accurately adapt to the complex shape contour of the target object, avoiding local stress concentration. With the two support components and two adjustment components working independently, pressure changes in different directions can be controlled separately, improving the accuracy of support shape adjustment.

[0070] In one exemplary embodiment, such as Figure 6 As shown, Figure 6 The third schematic diagram shows the structure supporting the adjustable shape. The first sensing component 210 includes a first number of first sensors 211, which are located in multiple partitions of the first sensing region L1 and arranged in a first matrix. The second sensing component 220 includes a second number of second sensors 221, which are located in multiple partitions of the second sensing region L2 and arranged in a second matrix. The second number is greater than the first number.

[0071] In this design, the first sensing elements 211 of the first sensing component 210 are arranged in a first matrix within the first sensing region L1, dividing the support surface of the first support component 110 into several independent sensing points. Each first sensing element 211 only collects the pressure signal of its corresponding point. Similarly, the second sensing elements 221 of the second sensing component 220 are arranged in a second matrix within the second sensing region L2, completing the point division of the second support region. This matrix arrangement upgrades pressure acquisition from the regional level to the unit level, enabling precise location of pressure anomalies. The higher number of sensing elements in the second region (L2) indicates a higher sensing unit density. Since the second support region (e.g., the human buttocks) is a pressure-sensitive area requiring higher precision pressure monitoring, while the first support region (e.g., the edge of the human back) has lower precision requirements, low-density sensing elements can be used to control costs. The low-density first sensor 211 collects basic pressure distribution data of the first support area, with a small signal transmission amount, suitable for judging the overall pressure status; the high-density second sensor 221 collects high-precision pressure distribution data of the second support area, which can capture minute pressure changes. The two types of signals are transmitted synchronously to the control mechanism 400 to form a high-precision pressure data map of the whole and the local area.

[0072] For example, the sensing mechanism 200 is composed of a flexible fabric pressure sensor array that fits against the human body's waist and buttocks. Specifically, it is distributed as follows: corresponding to the human body's waist support area (i.e., the first support area S1), there are 8 pressure sensing points arranged in two rows and four columns; corresponding to the human body's buttock support area (i.e., the second support area S2), there are 16 pressure sensing points arranged in four columns and four rows. This sensor array is used to collect simulated pressure distribution signals in real time after the human body sits down.

[0073] In this embodiment, the matrix arrangement supports flexible combination of sensing units to adapt to target objects of different sizes. At the same time, unit-level adjustment only performs actions on local small areas with abnormal pressure, without the need to adjust the entire support assembly. This reduces the frequency and amplitude of movement of the adjustment mechanism, reduces mechanical wear, and extends service life.

[0074] In one exemplary embodiment, it remains as follows Figure 6 As shown, the first adjustment component 310 includes a plurality of first adjustment members 311, which are respectively arranged opposite to a plurality of partitions of the first sensing area L1; the second adjustment component 320 includes an equal number of second adjustment members 321 and third adjustment members 322, which are respectively arranged opposite to the load-bearing partition L21 of the second sensing area L2, and the third adjustment members 322 are respectively arranged opposite to a plurality of transition partitions L22 of the second sensing area L2.

[0075] In this design, the first adjustment component 310 has multiple first adjustment elements 311, each corresponding to a different partition in the first sensing area L1. The range of motion of each first adjustment element 311 completely covers the support area of ​​its corresponding sensing partition, ensuring that the adjustment action of the first support component 110 can accurately respond to the pressure signal collected by the first sensor 211, thus preventing misalignment between the adjustment area and the pressure abnormality area. The second adjustment component 320 adopts a dual-type adjustment element partition configuration. The second adjustment element 321 is directly opposite the load-bearing partition L21 of the second sensing area L2 (i.e., the core force-bearing area of ​​the target object, such as the force center of the human buttocks), and the third adjustment element 322 is directly opposite the transition partition L22 (i.e., the edge connection area with smaller force fluctuations, such as the connection area from the human buttocks to the thighs). The number of second adjustment elements 321 and third adjustment elements 322 is the same, ensuring that the adjustment unit density of the load-bearing partition and the transition partition is consistent, laying the structural foundation for their coordinated adjustment.

[0076] For example, as before Figure 6 As shown, the adjustment mechanism 300 is located below the sensing mechanism 200 and consists of multiple independently controllable inflatable airbags. Specifically, it includes: a lumbar airbag group (i.e., the first adjustment component 310): composed of four small-volume airbags (i.e., the first adjustment element 311), corresponding to the four zones of the lumbar sensing area. A hip airbag group (i.e., the second adjustment component 320): composed of two large-volume airbags (i.e., the second adjustment element 321) and two small-volume airbags (i.e., the third adjustment element 322), wherein the large airbags are located in the main weight-bearing area of ​​the hips, and the small airbags are located on both sides of the hips and in the transition area at the root of the thighs, collectively corresponding to the multiple zones of the hip sensing area.

[0077] By setting different stress zones, the control mechanism 400, after receiving pressure data from the matrix sensor, can output differentiated adjustment commands to different adjustment components according to the priority of the zones. For example, in response to abnormal pressure in the load-bearing zone L21, the second adjustment component 321 is controlled to perform high-precision flexible adjustment, quickly adjusting the pressure in this area to the ideal threshold to ensure the stability of the core support. While the second adjustment component 321 is in operation, the third adjustment component 322 is controlled to perform adaptive follow-up adjustment, adjusting the support height / stiffness of the transition zone according to the shape change of the load-bearing zone, so that the support surface forms a smooth and gradual curve from the load-bearing zone to the surrounding area. The follow-up adjustment of the third adjustment component 322 can eliminate the support stiffness difference at the junction of the two types of zones. When the support height of the load-bearing zone increases, the height of the transition zone increases slightly in sync; when the stiffness of the load-bearing zone decreases, the stiffness of the transition zone is also finely adjusted accordingly to avoid stress concentration points at the junction. After the adjustment is completed, the matrix sensor collects the pressure signals of each zone again and feeds them back to the control mechanism 400. The control mechanism 400 focuses on verifying the pressure accuracy of the load-bearing zone and the pressure gradient between the transition zone and the load-bearing zone, and readjusts the support form until the pressure distribution of the entire support surface meets the high precision requirements of the core area and achieves a smooth transition throughout the entire area.

[0078] In this embodiment, by setting the adjustment component and the sensing zone directly opposite each other, the problem of misalignment between the adjustment area and the abnormal pressure area in the traditional adjustment structure is solved, the accuracy of the adjustment response is improved, and the support requirements of high-requirement scenarios such as ergonomics are met.

[0079] In one exemplary embodiment, it remains as follows Figure 6 As shown, the first adjusting member 311 has a first receiving cavity, the second adjusting member 321 has a second receiving cavity, and the third adjusting member 322 has a third receiving cavity; the volume of the first receiving cavity is the same as the volume of the third receiving cavity, and the volume of the second receiving cavity is greater than the volume of the first receiving cavity.

[0080] For the cavity containing the filling medium, the volume directly determines two core adjustment parameters: adjustment stroke: the larger the volume, the larger the compressible / flowable space of the medium, and the greater the extension or deformation stroke of the adjustment component; support stiffness: under the same medium pressure, a larger cavity volume results in greater deformation per unit pressure change, and more flexible support stiffness; a smaller cavity volume results in smaller deformation and more stable support stiffness. Based on this, differentiated volumes were designed for the functional positioning of the three types of adjustment components. The second adjustment component 321 has the largest volume, adapting to the large stroke and high flexibility adjustment requirements of the core load-bearing area. The first adjustment component 311 and the third adjustment component 322 have the same but smaller cavity volume, adapting to the small stroke and high stability adjustment requirements of non-core areas.

[0081] In response to abnormal pressure in the load-bearing zone, the control mechanism 400 outputs a large-stroke adjustment command to the second adjustment component 321: more medium is pumped into / out of the largest second receiving cavity via the pump body, causing the adjustment component to expand or deform significantly, quickly offsetting stress concentration in the core area (such as the heavy pressure on a human buttocks). For pressure fluctuations in the transition zone and the first sensing zone, the control mechanism outputs a small-stroke adjustment command to the third adjustment component 322 and the first adjustment component 311: a small amount of medium is pumped into / out of the smaller first / third receiving cavities, causing only a small deformation in the adjustment component, maintaining support stability while matching the morphological changes of the load-bearing zone. After adjustment, the sensors feed back pressure data, and the control mechanism focuses on verifying the pressure gradient between the load-bearing zone and the transition zone, ensuring smooth transition between the large-volume adjustment component's large movements and the small-volume adjustment component's small movements, ultimately forming a stable support surface.

[0082] In this embodiment, the second receiving cavity with the largest volume is precisely matched to the large stroke adjustment requirements of the load-bearing zone, which can quickly respond to the large pressure changes in the core area. The first and third receiving cavities with smaller volumes are adapted to the stable support requirements of the non-core areas, which can avoid the instability of the support surface caused by over-adjustment. This allows the adjustment performance and force characteristics of different areas to be precisely matched, improving the adaptation accuracy of the support form.

[0083] In one exemplary embodiment, such as Figure 7 As shown, Figure 7 This is the fourth structural diagram illustrating the adjustable support structure. The control mechanism 400 includes: a connecting assembly, an inflation assembly 410, an air storage assembly, a solenoid valve assembly, and a control assembly 420. It is understood that... Figure 7 This is an exemplary structural diagram of the adjustable support structure of this application, mainly used to clearly illustrate the core connection relationship and positional arrangement of the sensing mechanism 200, the adjustment mechanism 300, and the control component 420. For ease of understanding, the specific layout positions of the connecting components, the gas storage component, and the solenoid valve group are not indicated in the figure. This omission is only to simplify the drawing, highlight the relative positional relationship of the core components, and avoid visual confusion caused by the dense arrangement of auxiliary components such as pipelines and valves. In practical applications, the specific structural form, installation position, and arrangement of the connecting components, the gas storage component, and the solenoid valve group are not limited, as long as the following functions can be achieved: the connecting components can establish gas passages between the gas filling component and the gas storage component, and between the gas storage component and each adjustment component; the gas storage component can store compressed air and maintain a stable gas source pressure; the solenoid valve group can be controlled to realize the opening and closing control of the gas passages between the gas storage component and each adjustment component. The distribution positions of the above components can be reasonably configured with reference to the textual description of the control mechanism 400 in the following content.

[0084] Specifically, the connecting components include a first connector and a second connector; the air outlet of the inflation component 410 is connected to the air inlet of the air storage component through the first connector to generate compressed air during startup; the air outlet of the air storage component is connected to the first regulating component 311, the second regulating component 321, and the third regulating component 322 through the second connector to store the compressed air generated by the inflation component; the solenoid valve group includes multiple solenoid valves corresponding one-to-one with the first regulating component 311, the second regulating component 321, and the third regulating component 322, and the solenoid valves are located on the communication path between the air storage component and the first regulating component 311, the second regulating component 321, and the third regulating component 322; the control component 420 is electrically connected to the inflation component 410 and the solenoid valve group to control the startup of the inflation component 410 and to control the solenoid valves to open or close the communication path between the air storage component and the first regulating component 311, the second regulating component 321, and the third regulating component 322.

[0085] The inflation assembly 410, acting as a compressed air generation unit, has its outlet connected to the air storage assembly via a first connector, responsible for compressing and delivering air to the air storage assembly. The air storage assembly, acting as a pressure-stabilizing storage unit, stores compressed air, eliminating pressure fluctuations caused by intermittent operation of the inflation assembly and providing a stable air source for the regulating components. The solenoid valve group, acting as a precise distribution unit, includes solenoid valves corresponding one-to-one with the first regulating component 311, the second regulating component 321, and the third regulating component 322. Each solenoid valve is connected in series in the communication path between the air storage assembly and the corresponding regulating component. The first connector connects the inflation assembly 410 to the air storage assembly, while the second connector provides multi-path connections between the air storage assembly and the solenoid valve group and regulating components, ensuring directional gas transmission. The control assembly 420, acting as the core command unit, is electrically connected to the sensing mechanism 200, the inflation assembly, and the solenoid valve group, responsible for receiving pressure signals and outputting control commands.

[0086] The sensing mechanism 200 collects pressure data from the load-bearing zone L21, the transition zone L22, and the first sensing zone, and transmits it to the control component 420. The control component 420 compares the data with an ideal pressure model to determine the adjustment requirements of each zone. Upon startup, the control component 420 first activates the inflation component 410 to inflate the gas storage component until the pressure inside the gas storage component reaches a preset stabilization threshold. Then, the inflation component stops operating, and the gas storage component continuously provides a stable gas supply, avoiding energy waste and pressure fluctuations caused by continuous operation of the air pump.

[0087] Specifically, the control component 420 outputs on / off commands to the corresponding solenoid valves according to the adjustment requirements: For the second regulating component 321, it controls its corresponding solenoid valve to open the air storage component passage (filling) for a long time or open the atmospheric passage (releasing) for a long time, allowing a large amount of compressed air to enter / exit the second receiving cavity, achieving a large deformation of the regulating component and quickly correcting the pressure anomaly in the core load-bearing area; For the third regulating component 322 and the first regulating component 311, it controls its corresponding solenoid valve to open the air storage component / atmosphere passage for a short time, allowing a small amount of compressed air to enter / exit the first / third receiving cavity (small volume), achieving a small deformation of the regulating component, matching the shape changes of the load-bearing zones, and maintaining the smoothness of the support surface. After the adjustment action is completed, the sensing mechanism collects the pressure signal again and feeds it back to the control component 420. The control component 420 checks whether the pressure in each area meets the standard. If it does not meet the standard, it repeats the adjustment process until the pressure distribution conforms to the ideal model.

[0088] In this embodiment, the state of each regulating component can be independently controlled by corresponding solenoid valve groups and regulating components. By controlling the conduction time of the solenoid valves, the air volume requirements of different volume cavities can be accurately matched, ensuring the uniformity of pressure distribution on the support surface, thereby improving the accuracy of support shape adjustment.

[0089] In one exemplary embodiment, such as Figure 8 As shown, a support shape adjustment method is provided, including steps 802 to 806. Wherein:

[0090] S802: When the adjustment mechanism is in the initial support state, acquire the pressure signal collected by the sensing mechanism and convert the pressure signal into pressure data.

[0091] S804: Obtain the area to be adjusted based on pressure data and a preset pressure model.

[0092] S806: Adjust the support shape of the adjustment component corresponding to the area to be adjusted.

[0093] Optionally, when the adjustment mechanism is in its initial supported state, the target object contacts the supporting surface, generating pressure distribution. The matrix sensing component converts the mechanical signals of each zone into electrical signals. During this process, the differentiated design of the matrix arrangement and quantity of the sensors allows for the separate acquisition of basic pressure signals from non-core areas and high-precision pressure signals from load-bearing zones. After receiving the electrical signals, the control component performs filtering, amplification, and noise reduction through its built-in signal preprocessing module. This eliminates noise signals such as environmental vibration and electromagnetic interference, converting the analog electrical signals into calculable digital pressure data, providing a reliable data foundation for subsequent judgment.

[0094] The preset pressure model is based on ideal pressure distribution data pre-stored in the control component according to the support requirements of the target object. It includes zone pressure thresholds and pressure gradient standards. The control component uses a deviation analysis algorithm to compare the collected actual pressure data with the preset pressure model zone by zone: if the actual pressure of a zone exceeds the preset threshold, the zone is determined to be an area to be adjusted; if the zone pressure is within the threshold but the pressure gradient does not meet the standard, the area connecting the two zones is determined to be an area to be adjusted. Simultaneously, it can also prioritize multiple areas to be adjusted according to zone priority, addressing pressure anomalies in higher priority areas first.

[0095] Furthermore, the control component generates differentiated adjustment commands based on the location, priority, and pressure deviation of the area to be adjusted: for high-priority load-bearing zones, a large-flow inflation / deflation command is issued, controlling the corresponding solenoid valve to remain open for an extended period, driving the regulating component to undergo significant deformation; for transition zones or the first sensing zone, a small-flow inflation / deflation command is issued, controlling the solenoid valve to remain open for a short period, driving the regulating component to undergo minor deformation. After the adjustment is completed, the sensing mechanism collects pressure data again and verifies whether the pressure in the area to be adjusted has returned to the preset threshold. If it does not meet the standard, fine-tuning continues until the pressure distribution meets the model requirements.

[0096] In the above-mentioned support shape adjustment method, when the adjustment mechanism is in the initial support state, the pressure signal collected by the sensing mechanism is obtained and converted into pressure data. Based on the pressure data and the preset pressure model, the area to be adjusted is obtained, and the support shape of the adjustment component corresponding to the area to be adjusted is adjusted. This can accurately locate the pressure abnormal area and improve the accuracy of support shape adjustment.

[0097] In an exemplary embodiment, the control mechanism includes an inflation component, a solenoid valve, and an air storage component; the step of adjusting the support form of the adjustment mechanism corresponding to the area to be adjusted includes: when the pressure value of the area to be adjusted is lower than a preset pressure value, controlling the inflation component to start, and controlling the solenoid valve to open the communication path between the air storage component and the adjustment component corresponding to the area to be adjusted.

[0098] Optionally, the control component compares the real-time pressure data of the area to be adjusted with the threshold in the preset pressure model. When the pressure value is determined to be continuously lower than the preset pressure value, it is determined that the support stiffness of the area is insufficient (manifested as sinking of the support surface and poor fit between the target object and the support surface), triggering an inflation compensation adjustment command. During adjustment, the control component first detects the current pressure of the gas storage component: if the pressure inside the gas storage component is higher than the preset stabilization threshold, compressed air inside the gas storage component is used directly for gas supply without starting the inflation component; if the pressure inside the gas storage component is lower than the stabilization threshold, the inflation component is started first to replenish the gas storage component until the pressure reaches the target, and then the inflation component is stopped to avoid energy waste and pressure fluctuations caused by continuous operation of the inflation component.

[0099] Furthermore, the control component outputs a conduction command to the dedicated solenoid valve according to the type of regulating component corresponding to the area to be regulated: If the area to be regulated is a load-bearing zone: the corresponding solenoid valve is kept open for a long time, allowing a large amount of compressed air in the gas storage component to quickly fill the second receiving chamber. Utilizing the high deformation characteristics of the large-volume receiving chamber, the support surface is significantly raised, quickly compensating for insufficient pressure in the core area; If the area to be regulated is a transition zone / first sensing zone: the corresponding solenoid valve is kept open for a short time, supplementing only a small amount of compressed air, causing a slight rise in the support surface. While compensating for pressure, this ensures a smooth transition with the support structure of the surrounding areas. The solenoid valves corresponding to areas not to be regulated remain open to avoid a decrease in regulation efficiency due to gas diversion.

[0100] In this embodiment, by controlling the inflation component to start when the pressure value of the area to be adjusted is lower than the preset pressure value, and controlling the solenoid valve to open the communication path between the air storage component and the adjustment component corresponding to the area to be adjusted, it is possible to avoid misadjustment of non-target areas, improve the accuracy of support shape adjustment, and thus improve the fit between the support surface and the target object.

[0101] In an exemplary embodiment, the method further includes: when the pressure value of the area to be adjusted is not lower than a preset pressure value, controlling the inflation component to close, and controlling the solenoid valve to disconnect the communication path between the gas storage component and the adjustment component corresponding to the area to be adjusted.

[0102] Optionally, the control component continuously receives pressure data of the area to be adjusted from the sensing component. When the pressure value is continuously and stably within a preset threshold range, it determines that the support configuration of that area meets the requirements and triggers a pressure-holding control command. Upon stopping, the control component first outputs a command to shut down the inflation component. Once the pressure reaches the target, there is no need to continue generating compressed air. Stopping the inflation component prevents excessive pressure in the gas storage component and cuts off the gas supply at the source, preventing over-inflation of the regulating component and excessive lifting of the support surface due to continuous inflation. Afterward, the control component outputs a circuit-breaking command to the solenoid valve corresponding to the area to be adjusted, cutting off the connection between the gas storage component and the regulating component's receiving cavity. After the solenoid valve is broken, the pressure-holding monitoring phase begins. The sensing component continues to collect pressure data at a low frequency, and the control component monitors in real time whether the pressure in each area decreases. If the pressure in a certain area falls below the lower threshold due to gas leakage or other reasons, an inflation compensation flow will be triggered again.

[0103] In this embodiment, by controlling the inflation component to close and controlling the solenoid valve to disconnect the communication path between the air storage component and the adjustment component corresponding to the area to be adjusted when the pressure value of the area to be adjusted is not lower than the preset pressure value, the adjusted support height and stiffness can be accurately locked, ensuring that the fit between the support surface and the target object is stable and durable, thereby improving the safety and reliability of the support.
