Description

Bendable mattress edge protection structure control method, control system and bendable mattress Technical Field

[0001] The present invention relates to the field of bedding products, and in particular to a control method and control system for a bendable mattress edge protection structure, and a bendable mattress. Background Art

[0002] Existing mattresses are equipped with edge guards to prevent or delay edge collapse. The harder the edge guard, the better the anti-collapse effect. Consequently, issues such as a hard edge guard affecting user comfort or a soft edge guard causing edge collapse are common. When used in electric beds (or adjustable beds with bendable mattresses, the term "electric bed" used herein is the industry's commonly accepted term for a bendable bed consisting of multiple panels, with an electric drive mechanism located underneath one panel driving the other panels upward and downward), the edge guard has a certain hardness and shape. As the panel is tilted upward, the edge guard bends, easily causing wrinkles to form at the bend. This wrinkling not only affects the overall visual quality and quality of the mattress, but also affects user comfort.

[0003] To address the issue of mattress edge guards being too hard or too soft, which can lead to edge collapse, some mattresses use wider edge guards or a combination of composite materials with varying densities to provide better support. However, these edge guards have a relatively short lifespan and are prone to aging and collapse. Some mattresses also incorporate adjustable airbags in the edge guards, which inflate and deflate to adjust the edge guard's firmness and improve its collapse prevention. However, these adjustable airbags suffer from poor air permeability and can still cause wrinkles in the edge guards when the mattress is bent. Summary of the Invention

[0004] The object of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a control method for a bendable mattress edge guard structure, a control system and a bendable mattress. The bendable mattress edge guard structure is changed, and a segmented air bag or a plurality of air bags arranged at intervals are added therein. The hardness of the mattress edge guard is adjusted by adjusting the inflation volume of the air bag. By locally adjusting the inflation volume of the air bag corresponding to the bending part of the mattress edge guard, the bending part of the edge guard structure is made wrinkle-free, which effectively prevents the edge from collapsing and has a corresponding hardness to achieve good supporting force, which is beneficial to improving the service life and comfort of the mattress and also helps to ensure that the mattress always maintains good quality during use.

[0005] The above technical objectives of the present invention are primarily achieved through the following technical solution: a method for controlling a bendable mattress edge guard structure, characterized by: selecting or setting a sitting feel parameter for the edge guard; adjusting the state of airbags in the edge guard structure based on the sitting feel parameter; collecting angle data of the bent portions of the edge guard structure; and determining the angle data and adjusting the state of the airbags to ensure that the bent portions of the edge guard structure are wrinkle-free and have a corresponding degree of firmness. The angle data is used to determine the degree of bending or flattening of the airbags, and the inflation volume of the flat portions of the bent airbags is then adjusted to ensure overall edge guard firmness, the inflation volume of the bent portions is adjusted to prevent wrinkles, or the overall inflation volume of the flat airbags is adjusted to ensure overall edge guard firmness and achieve good support.

[0006] As a further improvement and supplement to the above-mentioned technical solution, the present invention employs the following technical measures: collecting air pressure data from the airbags; based on this air pressure data, determining whether there is an individual on the edge guard structure; if not, activating the airbags to cycle inflation and deflation, keeping the edge guard structure in a dynamic, ventilation mode. The ventilation mode is designed to provide effective ventilation for the edge guard structure, dissipating heat and moisture, which is beneficial for protecting the edge guard structure and the user's health. The ventilation mode is activated only when no one is present, minimizing disruption to the user.

[0007] As a priority, set a time threshold T, collect air pressure data every T time, and save the air pressure data to form an air pressure data set; set an air pressure threshold P, and judge the size of the air pressure data and the air pressure threshold P; if the air pressure data is greater than or equal to the air pressure threshold P, it means that there is someone on the guardrail, and jump to angle collection; if the air pressure data is less than the air pressure threshold P, it means that there is no one on the guardrail, and collect temperature and humidity data every T time, and save temperature data WD and humidity data SD respectively; set the ambient temperature and humidity threshold WDT and ambient humidity threshold SDT; if WD ≥ WDT, or SD is greater than or equal to SDT, turn on the ventilation mode; otherwise, jump to angle collection.

[0008] As a priority, the air pressure data at least includes the air pressure data P100 of the head and shoulder bending area, the air pressure data P200 of the waist and hip bending area, and the air pressure data P300 of the foot bending area, and the corresponding air pressure data sets are: {P100, P200, P300}.

[0009] As a priority, set a time threshold T, collect angle data every T time, and save the angle data to form an angle data set; set an angle threshold W, and judge the size of the angle data and the angle threshold W; if it is greater than or equal to the angle threshold W, search and match the corresponding airbag pressure parameters according to the airbag pressure database; adjust the airbag state according to the airbag pressure parameters so that the hardness of the edge protection structure adapts to the bending angle; otherwise, there will be no wrinkles at the bending part of the edge protection structure, and the airbag cycle of inflation and deflation will be turned on to enter the ventilation mode.

[0010] As a priority, the angle data at least includes the head-shoulder bending area angle data W100, the waist-hip bending area angle data W200, W201 and the foot bending area angle data W300, and the corresponding angle data sets are: {W100, W200, W201, W300}.

[0011] The technical solution of the second technical subject of the present invention: a control system for a bendable mattress edge guard structure, characterized in that it is used to execute the above-mentioned bendable mattress edge guard structure control method, the control system includes a microcontroller unit, an angle acquisition unit, an air pressure acquisition unit and an airbag drive unit electrically and signal-connected to the microcontroller unit, the angle acquisition unit and the air pressure acquisition unit are respectively used to collect angle data and air pressure data for enabling the airbag drive unit to adjust the hardness of the airbag.

[0012] As a priority, the bendable mattress edge guard structure control system also includes a temperature and humidity detection unit electrically and signal-connected to the microcontroller unit. The temperature and humidity detection unit is used to collect temperature and humidity data of the edge guard structure. The microcontroller unit receives the temperature and humidity data and compares it with the ambient temperature and humidity to enable the edge guard structure to turn on the ventilation mode.

[0013] The technical solution of the third technical subject matter involved in the present invention: a bendable mattress provided with a side guard structure, comprising a bendable mattress body, characterized in that it also includes two sets of side guard structures, which are respectively arranged on two opposite sides in the longitudinal direction of the mattress body, and along the longitudinal direction of the side guard structures, the side guard structures are provided with segmented airbags or a plurality of airbags arranged at intervals, and a control system for controlling the movement of the airbags to make the side guard structure bendable, wherein the control system is the above-mentioned bendable mattress side guard structure control system.

[0014] Priority is given to the side guard structure being provided with at least a head-shoulder bendable area, a waist-hip bendable area, and a foot bendable area along the length direction of the side guard structure, the angle acquisition unit being respectively provided in each bendable area, the side guard structure being further provided with a deformable groove, the airbag being provided in the deformable groove, and the deformable groove being used to assist in absorbing wrinkles caused by the bending of the side guard structure.

[0015] To ensure a better fit and support for the body when the mattress is bent, it is often designed with a head-and-shoulder area, a waist-and-hip area, and a foot-bend area, while the rest of the mattress is typically flat. A control system for a flexible mattress edge guard structure executes a control method for the flexible mattress edge guard structure, controlling the inflation volume of airbags in the head-and-shoulder area, waist-and-hip area, and foot-bend area to ensure the edge guard structure is wrinkle-free when bent. The inflation volume of airbags in the straight areas of the mattress is also controlled, with the inflation volume of airbags in different straight areas being either the same or different, to ensure the edge guard structure provides the support required by the user. When the mattress is laid flat, the inflation volume of all airbags in the edge guard structure is controlled (the inflation volume of airbags in different areas can be the same or different) to ensure that the entire edge guard structure has good support.

[0016] The present invention has the beneficial effects:

[0017] 1. Make the bent edge structure wrinkle-free: According to the bending degree of the edge guard, by adjusting the inflation and deflation of the airbags at the bent part of the edge guard structure, the expansion and contraction of the airbags can be automatically adjusted, that is, the inflation volume of the airbags can be controlled, thereby avoiding wrinkles at the bent part and helping to improve the bending performance of the mattress.

[0018] 2. Improve the air permeability and heat dissipation performance of the mattress: In order to avoid disturbing the user on the mattress, when no one is on the mattress, the airbags are cyclically adjusted to inflate and deflate, driving the air flow around the edge structure, thereby driving the air flow circulation inside the mattress, improving the air permeability and heat dissipation performance of the edge structure, and thus helping to improve user comfort and health.

[0019] 3. Improve the sitting feel of the mattress edge guard: By setting up segmented airbags or airbags set at several intervals, users can adjust the hardness and softness of different areas of the edge guard structure according to their own needs. This not only solves the problem of edge guard collapse when sitting, but also meets the personalized needs of different people for the sitting feel of the edge guard structure.

[0020] 4. By providing a plurality of deformable grooves running transversely (i.e., along the width direction of the mattress) on the mattress edge guard, segmented airbags or a plurality of airbags arranged at intervals are arranged in the deformable grooves. The deformable grooves have a positioning effect on the airbags. At the same time, the deformable grooves can also absorb the amount of wrinkles when the edge guard structure is in a bent state, further ensuring that the edge guard structure is wrinkle-free when in a bent state.

[0026] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. The edge guard, edge guard structure and mattress edge guard structure involved in the present invention are the same structure.

[0027] Example 1: As shown in Figures 1 and 2, the technical solution of the first technical subject of the present invention is as follows:

[0028] A control method for a bendable mattress edge guard structure includes: selecting or setting sitting feeling parameters of the edge guard; adjusting the state of an airbag in the edge guard structure according to the sitting feeling parameters; collecting angle data of a bending portion of the edge guard structure; judging the angle data and adjusting the state of the airbag so that the bending portion of the edge guard structure is wrinkle-free and has a corresponding hardness.

[0029] Through the angle data, the degree of bending or flatness of the airbag is determined, and then the inflation volume of the flat part of the bent airbag is adjusted to ensure the overall hardness of the edge guard, the local inflation volume of the bent part is adjusted to avoid wrinkles, or the overall inflation volume of the overall flat airbag is adjusted to ensure the overall hardness of the edge guard and achieve good support.

[0030] To further enhance the performance of the edge guard, airbag pressure data is collected. Based on this pressure data, the presence of an occupant on the edge guard is determined. If unoccupied, the airbag is activated to cycle inflation and deflation (in short, inflation and deflation), keeping the edge guard in a dynamic, ventilation mode. This ventilation mode ensures effective ventilation of the edge guard, dissipating heat and moisture, which is beneficial for protecting the edge guard and the health of the user. Enabling ventilation mode when no one is on the edge guard reduces disruption to the user.

[0031] In order to further improve the degree of automatic control, a time threshold T is set, and air pressure data is collected and saved every T time to form an air pressure data set; an air pressure threshold P is set to judge the size of the air pressure data and the air pressure threshold P; if the air pressure data is greater than or equal to the air pressure threshold P, it means that there is someone on the edge guard, and the process jumps to angle collection; if the air pressure data is less than the air pressure threshold P, it means that there is no one on the edge guard, and temperature and humidity data are collected every T time, and temperature data WD and humidity data SD are saved respectively; the ambient temperature and humidity threshold WDT and ambient humidity threshold SDT are set; if WD ≥ WDT, or SD is greater than or equal to SDT, the ventilation mode is turned on; otherwise, the process jumps to angle collection.

[0032] The air pressure data at least includes the air pressure data P100 of the head and shoulder bending area, the air pressure data P200 of the waist and hip bending area, and the air pressure data P300 of the foot bending area, and the corresponding air pressure data sets are: {P100, P200, P300}.

[0033] Similarly, in order to improve the degree of automation, a time threshold T is set, and angle data is collected every T time, and the angle data is saved to form an angle data set; an angle threshold W is set to judge the size of the angle data and the angle threshold W; if it is greater than or equal to the angle threshold W, the corresponding airbag pressure parameters are searched and matched according to the airbag pressure database; the airbag state is adjusted according to the airbag pressure parameters so that the hardness of the edge protection structure adapts to the bending angle; otherwise, there are no wrinkles at the bending part of the edge protection structure, and the airbag cycle of inflation and deflation is turned on to enter the ventilation mode.

[0034] The angle data at least includes the head-shoulder bending area angle data W100, the waist-hip bending area angle data W200, W201 and the foot bending area angle data W300, and the corresponding angle data sets are: {W100, W200, W201, W300}.

[0035] When the control method of the bendable mattress edge protection structure is actually applied, the control process is as follows:

[0036] S100, mattress edge protection sitting feeling selection:

[0037] After the mattress edge guard is powered on, the user selects the mattress edge guard's sitting feel through a wireless communication unit, including but not limited to an app, WeChat mini-program, or remote control. Once the user has selected the mattress edge guard's sitting feel, the control system controls the output state (i.e., inflation volume) of the corresponding airbags based on the local mattress edge guard's sitting feel and airbag pressure state database model. After completing step S100, the process proceeds to step S200.

[0038] S200: Airbag pressure state acquisition and output state adjustment when the mattress is bent or lying flat. The specific steps are as follows:

[0039] S201. Collecting the bending state of the mattress through the electric bed or the adjustable angle recognition unit:

[0040] Set a time threshold T, and collect the mattress bending state through the electric bed or adjustable angle recognition unit every T time, and save the head and shoulder bending area angle as W100, the waist and hip bending area angle as W200 and W201, and the leg bending area angle as W300. After completing the mattress bending state collection, jump to step S202.

[0041] S202: Determine whether each edge protection bending area is in a bending state:

[0042] The mattress bending angle data collected in step S201 is used to form an angle dataset {W100, W200, W201, W300} for edge bend determination. During this determination, an angle threshold, W, is set. If the bending angle data for any bend area in the angle dataset {W100, W200, W201, W300} is greater than or equal to W, the process proceeds to S204; otherwise, the process proceeds to S203.

[0043] S203. Keep the mattress flat while the edge protector provides a comfortable sitting experience.

[0044] If the mattress is in a flat state (i.e. lying flat), the airbag pressure state corresponding to the edge protection sitting feeling is maintained (i.e. having a certain amount of inflation, maintaining a certain hardness and good support force), and after completion, jump to S300.

[0045] S204: Adjust the status output of the edge protection airbag in the corresponding area according to the pressure model database of the edge protection airbag bending state:

[0046] If the mattress is in a bent state, the angle data set {W100, W200, W201, W300} in the bent state is searched and matched with the pressure model database of the edge guard airbag in the bent state, and the state output of the airbag in the corresponding area of ​​the edge guard is adjusted (to control the appropriate inflation volume in the airbag). After completion, jump to S300.

[0047] S300: When no one is sitting or standing on the mattress edge guard, the airbag circulation inflation and deflation ventilation mode is turned on, including the following steps:

[0048] S301, using the airbag pressure collection unit to collect real-time air pressure status of the airbags in each edge protection bending area:

[0049] Every T time, the airbag pressure collection unit collects the real-time air pressure status of each edge bend area airbag, and saves the air pressure status of the head and shoulder bend area airbag L100 as P100, the air pressure status of the waist and hip bend area airbag L200 as P200, and the air pressure status of the leg bend area airbag L300 as P300. After completion, jump to step S302.

[0050] S302, mattress edge guard occupancy or non-occupancy status (abbreviated as: occupancy or non-occupancy status) detection:

[0051] Set a threshold value P, and compare the airbag pressure states {P100, P200, P300} of each bending area with the size of P to detect whether the mattress edge guard is occupied. After completion, jump to S303.

[0052] S303, mattress edge guard whether there is someone in the state:

[0053] If the air pressure state data of any bending area in the air pressure data set {P100, P200, P300} is greater than or equal to P, it is determined to be in a human state, and the process jumps to S201. Otherwise, it is determined to be in an unmanned state, and the process jumps to S304.

[0054] S304: Collect the temperature and humidity of the surrounding environment of the mattress through the temperature and humidity detection unit:

[0055] At every time interval T, the temperature and humidity of the surrounding environment of the mattress are collected through the temperature and humidity detection unit, and the temperature and humidity data bits WD and SD are saved respectively. Jump to S305.

[0056] S305: Determine whether the ambient temperature or humidity is too high.

[0057] Preferably, an ambient temperature threshold WDT and an ambient humidity threshold SDT are set, and if WD is greater than or equal to WDT, or SD is greater than or equal to SDT, it indicates that the ambient temperature or humidity is too high, and the process jumps to S306. Otherwise, the process jumps to S201.

[0058] S306: Start the ventilation mode formed by cyclic inflation and deflation of the airbag.

[0059] When the ambient temperature and / or humidity is too high, the ventilation mode can be used to drive the circulation of air around the mattress edge guard, thereby improving the temperature and humidity quality of the edge guard environment. After completion, jump to S201.

[0060] Repeat the above steps S100 to S300 (including their respective sub-steps such as S201 to S204, S301 to S306) until the power is turned off or the user turns off the edge protection adjustment.

[0061] Example 2: As shown in FIG3 , the technical solution of the second technical subject of the present invention is as follows:

[0062] The bendable mattress edge guard structure control system L400 is used to execute the bendable mattress edge guard structure control method described in Example 1. The control system includes a microcontroller unit L40000, an angle acquisition unit (i.e., an electric bed or adjustable bed angle recognition unit L40040) electrically and signal-connected to the microcontroller unit, an air pressure acquisition unit, and an airbag drive unit. The angle acquisition unit and the air pressure acquisition unit are respectively used to collect angle data and air pressure data for enabling the airbag drive unit to adjust the hardness of the airbag.

[0063] The air pressure collection unit includes the head and shoulder flexion area airbag pressure collection unit L40010, the waist and hip flexion area airbag pressure collection unit L40020, and the leg flexion area airbag pressure collection unit L40030. The airbag drive unit includes the head and shoulder flexion area airbag pressure output drive unit L40011, the waist and hip flexion area airbag pressure output drive unit L40021, and the leg flexion area airbag pressure output drive unit L40031.

[0064] Furthermore, the control system of the bendable mattress edge guard structure also includes a temperature and humidity detection unit L40050 electrically and signal-connected to the microcontroller unit L40000. The temperature and humidity detection unit is used to collect temperature and humidity data of the edge guard structure. The microcontroller unit receives the temperature and humidity data and compares it with the ambient temperature and humidity to enable the edge guard structure to enter ventilation mode.

[0065] In order to facilitate production, processing, assembly and maintenance, the control system is often set in the control box L400. In this embodiment, the control system is also provided with a wireless communication unit L40060.

[0067] A bendable mattress provided with an edge guard structure comprises a bendable mattress body, two sets of edge guard structures respectively arranged on two opposite sides in the longitudinal direction of the mattress body, segmented airbags or a plurality of airbags arranged at intervals along the longitudinal direction of the edge guard structure, and a control system for controlling the movement of the airbags to make the edge guard structure bendable, wherein the control system is the bendable mattress edge guard structure control system described in Example 2.

[0068] Along the length direction of the edge protection structure, the edge protection structure is provided with at least a head and shoulder bendable area, a waist and hip bend area, and a foot bend area, the angle acquisition unit is respectively arranged in each bending area, and the edge protection structure is also provided with a deformable groove, the airbag is arranged in the deformable groove, and the deformable groove is used to assist in absorbing wrinkles caused by the bending of the edge protection structure.

[0069] To ensure a better fit and support for the body when the mattress is bent, it is often designed with a head-and-shoulder area, a waist-and-hip area, and a foot-bend area, while the rest of the mattress is typically flat. A control system for a flexible mattress edge guard structure executes a control method for the flexible mattress edge guard structure, controlling the inflation volume of airbags in the head-and-shoulder area, waist-and-hip area, and foot-bend area to ensure the edge guard structure is wrinkle-free when bent. The inflation volume of airbags in the straight areas of the mattress is also controlled, with the inflation volume of airbags in different straight areas being either the same or different, to ensure the edge guard structure provides the support required by the user. When the mattress is laid flat, the inflation volume of all airbags in the edge guard structure is controlled (the inflation volume of airbags in different areas can be the same or different) to ensure that the entire edge guard structure has good support.

[0070] Furthermore, a number of deformable grooves are provided on the edge protection structure, and the airbags are respectively provided in the deformable grooves. The deformable grooves have a positioning effect on the airbags. At the same time, the deformable grooves can also absorb the amount of wrinkles when the edge protection structure is in a bent state, further ensuring that there are no wrinkles when the edge protection structure is in a bent state.

[0071] In this technical solution, the edge guard L500 primarily provides edge support for the mattress, including materials such as sponge and 3D materials. The upper half of the edge guard L500 is equipped with transversely extending deformable grooves, including deformable grooves L101 in the head and shoulder area, L201 in the waist and hip area, and L301 in the leg area. These grooves primarily accommodate the adjustable airbags in the edge guard and allow the edge guard to bend vertically when the mattress is bent to accommodate products such as electric or adjustable beds. The deformable grooves can be round, square, or any other suitable shape for airbag filling.

[0072] A control box deformable groove L401 is provided in the tail area of ​​the edge guard, mainly to provide an installation position for the control box L400.

The airbags in each area mainly provide adjustable sitting support for each area of ​​the mattress edge guard, and at the same time provide deformation space for the mattress to adapt to products such as electric beds or adjustable beds by controlling the inflation and deflation of the airbags to change the bending of the edge guard sponge in the vertical plane.
