[0002] An adaptive mattress is a type of mattress that can automatically adjust its support and comfort based on changes in body pressure, temperature, and posture. It can help users achieve better sleep quality, reduce body pressure, and prevent health problems caused by improper sleeping posture.
[0003] In related technologies, adaptive mattresses primarily rely on mechanical adjustments, supplemented by airbags for support adjustment. Adaptive mattresses feature an array of multiple airbags, but because each airbag needs to be connected to a control panel, all air tubes are connected to a single control panel, resulting in complex airflow. This limits the number of airbags that can be used, restricting the selection of only a few for auxiliary support and reducing the mattress's comfort. Utility Model Content
[0004] The purpose of this invention is to provide an adaptive air mattress and furniture to solve the technical problem that the complex airbag layout of an adaptive mattress affects the arrangement of the airbags and reduces the comfort of the mattress.
[0005] To achieve the above objectives, this utility model provides an adaptive air cushion, which includes a sensing layer, a sponge layer, an airbag layer, and a control component, wherein the sponge layer is disposed between the sensing layer and the airbag layer.

The airbag control module is connected to the air inlet of the main air tube, and each branch air tube is connected in parallel to the air outlet of the main air tube. Each branch air tube extends to each row of airbags and connects to each airbag.
[0008] An air valve assembly is connected between the air distribution pipe and each of the airbags. The air valve assembly is electrically connected to the airbag control module. The airbag control module controls the air valve assembly to supply air to each of the airbags.
[0009] In the adaptive air cushion of this application, each air bladder corresponds to a plurality of pressure sensors in a direction perpendicular to the sensing layer.
[0010] In the adaptive air cushion of this application, each airbag is connected to a first air inlet pipe, and the first air inlet pipe is connected to a first exhaust pipe;
[0011] The valve assembly includes an intake valve and an exhaust valve, with the intake valve located on the first intake pipe and the exhaust valve located on the first exhaust pipe.
[0012] In the adaptive air cushion of this application, the control component further includes an inflation device, which is connected to the airbag control module and is used to supply air to the airbag.
[0013] In the adaptive air cushion of this application, the airbag control module includes a control board, an air chamber, a second air inlet pipe and a second air outlet pipe. The air chamber is disposed on the control board. The two ends of the second air inlet pipe are respectively connected to the inflation device and the air chamber.

[0017] Secondly, this application also provides a piece of furniture, which includes a body and the adaptive air cushion, the adaptive air cushion being disposed on the body.
[0018] This utility model provides an adaptive air cushion, the advantages of which are:
[0019] This invention relates to an adaptive air cushion comprising a sensing layer, a sponge layer, an airbag layer, and a control component. The sensing layer includes a substrate and an array of pressure sensors mounted on the substrate. The airbag layer comprises multiple rows of airbags arranged side-by-side. The sponge layer is connected to the substrate and the airbags on both sides. The control component includes an airbag control module, a main air tube, and multiple branch air tubes. The airbags in each row are first connected to the branch air tubes, and then each branch air tube is connected to the main air tube. The main air tube serves as the main air intake channel, introducing gas from the airbag control module and distributing it to each row of airbags through the multiple branch air tubes.

[0030] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
[0031] like Figures 1 to 3 As shown, this embodiment of the present invention provides an adaptive air cushion 100, which includes a sensing layer 10, a sponge layer 20, an airbag layer 30, and a control component. The sponge layer 20 is disposed between the sensing layer 10 and the airbag layer 30. The sensing layer 10 includes a substrate 11 and pressure sensors 12 arrayed on the substrate 11. The substrate 11 can deform under external force. The airbag layer 30 includes multiple rows of airbags 31 arranged side by side. The two sides of the sponge layer 20 are respectively connected to the substrate 11 and the airbags 31. The control assembly includes an airbag control module 40, a main air tube 41, and multiple branch air tubes 42. The airbag control module 40 is connected to the air inlet end of the main air tube 41, and each branch air tube 42 is connected in parallel to the air outlet end of the main air tube 41. Each branch air tube 42 extends to each row of airbags and connects to each airbag 31. An air valve assembly 43 is connected between the branch air tube 42 and each airbag 31. The air valve assembly 43 is electrically connected to the airbag control module 40, and the airbag control module 40 controls the air valve assembly 43 to supply air to each airbag 31.
[0032] In the sensing layer 10, the sensing layer 10 includes a substrate 11 and pressure sensors 12 arrayed on the substrate 11. The substrate 11 can deform under external force to form flexible pressure sensors 12. For example, the substrate 11 is made of fabric, and conductive wires are interlaced along the length and width of the fabric by embroidery to form flexible pressure sensors 12. Alternatively, the substrate 11 is made of PI film or PET film, and silver paste is screen-printed onto the PI film or PET film to form flexible pressure sensors 12. It should be noted that this embodiment does not specifically limit the formation method of the sensing layer 10.
[0033] In this embodiment, by arraying pressure sensors 12 on the substrate 11, the pressure distribution of different parts of the human body on the sensing layer 10 can be accurately sensed.
[0034] In the sponge layer 20, the material of the sponge layer 20 is sponge. Sponge has good elasticity and softness. When the human body applies pressure to the sensing layer 10, the sponge layer 20 can play a cushioning role and improve the comfort of the air cushion.
[0035] In the airbag layer 30, each airbag 31 is independently controlled by a valve assembly 43 connected to it. The airbag control module 40 controls the opening and closing of the valve assembly 43 and the air supply based on the pressure information fed back by the pressure sensor 12, thereby regulating the inflation or deflation of each airbag 31.
[0036] Based on the above technical solution, the airbags 31 in each row of airbags 31 are first connected to the air distribution pipes 42, and then each air distribution pipe 42 is connected to the main air pipe 41. The main air pipe 41 is the main air intake pipe, used to introduce gas from the airbag control module 40, and distribute the gas to each row of airbags 31 through multiple air distribution pipes 42. This makes the air path more orderly, the air path layout simple and regular, optimizes the air path layout, avoids messy connections of all air pipes, and solves the problem of complex air path. On this basis, more airbags 31 can be set up side by side, and the support of the air cushion is provided by a large number of airbags 31, thereby improving the comfort of the air cushion.
[0037] It should be noted that the adaptive air cushion 100 of this embodiment can be applied to furniture products such as sofas, mattresses, and chairs. For example, when the adaptive air cushion 100 is applied to a mattress, the sensing layer 10, the sponge layer 20, and the airbag layer 30 are stacked sequentially from top to bottom. The airbag layer 30 is located on the mattress body, the sensing layer 10 is located on the upper layer that is in contact with the human body, and the sponge layer 20 is located in the middle layer, improving cushioning comfort. When a person lies on the mattress, the pressure sensor 12 detects the pressure distribution of the human body. Based on the pressure distribution detected by the pressure sensor 12, the airbag control module 40 controls the opening and closing of the air valve assembly 43 and the air supply, thereby supplying air to each airbag 31 and adjusting the support height of each airbag 31 to achieve adaptive adjustment.
[0038] In some embodiments, such as Figure 2 As shown, in the direction perpendicular to the sensing layer 10, each airbag 31 corresponds to multiple pressure sensors 12.
[0039] Specifically, multiple pressure sensors 12 are distributed in the vertical area corresponding to the airbag 31, which can more comprehensively capture the pressure exerted by different parts of the human body on the sensing layer 10, thereby more accurately reflecting the pressure distribution between the human body and the airbag contact surface.
[0040] For example, when a person lies on the air cushion in different positions, the pressure and distribution on the sensing layer 10 vary at different parts of the body. Multiple pressure sensors 12 are arrayed to provide accurate pressure information to the airbag control module 40, which then adjusts the opening and closing of the air valve assembly 43 to make the airbag 31 adapt to the curves of the human body and provide a more fitting support effect.
[0041] In some embodiments, such as Figure 3 and Figure 4As shown, each airbag 31 is connected to a first air intake pipe 44, and the first air intake pipe 44 is connected to a first exhaust pipe 45; the air valve assembly 43 includes an air intake valve 431 and an exhaust valve 432, the air intake valve 431 is located on the first air intake pipe 44, and the exhaust valve 432 is located on the first exhaust pipe 45.
[0042] Specifically, the airbag control module 40 can individually control the on / off state of the inlet valve 431 and the outlet valve 432 corresponding to each airbag 31, thereby achieving independent control of the inflation and deflation of each airbag 31. During inflation, the airbag control module 40 controls the inlet valve 431 to open and the outlet valve 432 to close, so that gas enters the first inlet pipe 44 from the distribution pipe 42 through the inlet valve 431 and enters the airbag 31 from the first inlet pipe 44 to inflate the airbag 31; during deflation, the module controls the outlet valve 432 to open and the inlet valve 431 to close, preventing gas from entering the airbag 31 from the first inlet pipe 44, and simultaneously releasing the gas inside the airbag 31, thereby deflating the corresponding airbag 31 and adjusting the support height of the airbag 31.
[0043] In some embodiments, the intake valve 431 and the exhaust valve 432 may be solenoid valves.
[0044] In some embodiments, such as Figure 5 As shown, the control assembly also includes an inflation device 46, which is connected to the airbag control module 40 and is used to supply air to the airbag 31.
[0045] Specifically, the inflation device 46 is controlled by the airbag control module 40 to supply air to the airbag 31, so that the airbag 31 does not rely on an external air source when it is inflated. Based on the pressure information fed back by the pressure sensor 12, the inflation device 46 is started and stopped in real time to provide inflation gas to the airbag 31, thereby improving the adaptive adjustment capability of the airbag.
[0046] In some embodiments, the inflation device 46 is an air pump. Of course, the inflation device 46 can also be other devices capable of inflation.
[0047] In some embodiments, such as Figure 5 As shown, the airbag control module 40 includes a control board 401, an air chamber 402, a second air inlet pipe 403, and a second exhaust pipe 404. The air chamber 402 is located on the control board 401. The two ends of the second air inlet pipe 403 are respectively connected to the inflation device 46 and the air chamber 402. The second exhaust pipe 404 and the main air pipe 41 are respectively connected to the air chamber 402.
[0048] Specifically, the second air intake pipe 403, the second exhaust pipe 404, and the main air pipe 41 are connected to different positions of the air chamber 402. The inflation device 46 inflates the main air pipe 41 through the second air intake pipe 403 and the air chamber 402, thereby providing inflation gas for the airbag 31. If it is necessary to deflate the entire adaptive air cushion 100, the inflation device 46 is closed, and the gas in the main air pipe 41 is discharged through the second exhaust pipe 404.
[0049] In some embodiments, such as Figure 2 As shown, the sponge layer 20 is detachably connected to the substrate 11 and the airbag 31.
[0050] It is understandable that users can flexibly replace the sponge layer 20 with different thicknesses, densities, or materials according to their own needs. For example, some users prefer a softer sponge layer 20 for a softer touch, while others need a firmer sponge layer 20 to provide stronger support.
[0051] Specifically, the base 11 can be a flexible material such as fabric, and the sponge layer 20 can be fixed to the base 11 and the airbag 31 by means of sewing thread or Velcro. The sponge layer 20 of different thicknesses, densities or materials can be disassembled and replaced according to one's own needs.
[0052] In some embodiments, such as Figure 2 As shown, the sensing layer 10 also includes a data acquisition board 13. The pressure sensor 12 and the airbag control module 40 are electrically connected to the data acquisition board 13. The data acquisition board 13 is used to acquire the signal of each pressure sensor 12.
[0053] Specifically, in traditional air cushions, each pressure sensor 12 is electrically connected to the airbag control module 40 via electrical wires, resulting in complex and messy wiring. In this embodiment, the acquisition board 13 is integrated into the substrate 11 and electrically connected to each pressure sensor 12. Each pressure sensor 12 first transmits its signal to the acquisition board 13, and then the acquisition board 13 transmits the signal to the airbag control module 40 in a unified manner, which can reduce the number of electrical wires.
[0054] In some embodiments, in a direction perpendicular to the sensing layer 10, the projected area of the sponge layer 20 and the airbag layer 30 is greater than or equal to the projected area of the sensing layer 10.
[0055] Specifically, not all areas of the sponge layer 20 need to be covered with the sensing layer 10; the placement is determined based on the actual situation. The function of the sponge layer 20 and the airbag layer 30 is to provide support and cushioning for the human body. The projected area of the sponge layer 20 and the airbag layer 30 is greater than or equal to the projected area of the sensing layer 10, ensuring that the area where the human body contacts the sensing layer 10 is supported. The sponge layer 20 deforms according to the curves of the human body and the pressure distribution, while the airbag layer 30 adjusts its height based on the pressure information fed back by the sensing layer 10, providing users with support that more closely conforms to the body's curves and improves comfort.
[0056] Secondly, embodiments of this application also provide a piece of furniture, which includes a body and an adaptive air cushion 100, the adaptive air cushion 100 being disposed on the body.
[0057] Specifically, the advantages of the adaptive air cushion 100 are as described in the previous embodiments and will not be repeated here. The furniture can be a sofa, mattress, or chair, etc. Applying the adaptive air cushion 100 to the body of the sofa, mattress, or chair can improve the comfort of the furniture.
