Technical Field

[0001] This invention relates to the field of smart health furniture technology, specifically to an airbag seat cushion with pressure and monitoring sensors. Background Technology

[0002] Airbag seat cushions are a comfortable office aid that distributes body weight through airbag inflation, reducing the risk of pressure sores and improving the health and work efficiency of people who sit for long periods of time. They are especially suitable for people who sit for long periods of time.

[0003] Existing airbag seat cushions contain several inflatable airbags to distribute the pressure on the buttocks. However, due to individual sitting postures, the pressure on the left and right sides of the buttocks may be uneven, and prolonged use can exacerbate these posture problems. In addition, existing airbag seat cushions have relatively limited functionality. Therefore, we propose an airbag seat cushion with pressure and monitoring sensors. Summary of the Invention

[0004] The purpose of this invention is to provide an airbag seat cushion with pressure and monitoring sensors. This invention aims to provide an intelligent health seat cushion that can sense the pressure distribution of the human body's sitting posture in real time, automatically adjust the airbag pressure to correct the sitting posture, and simultaneously monitor the user's heart rate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an airbag seat cushion with pressure and monitoring sensors, comprising an airbag seat cushion, wherein airbag bodies are equidistantly installed inside the airbag seat cushion, the airbag bodies comprising outer ring airbags and inner ring airbags, the outer ring airbags being disposed around both ends of the airbag seat cushion, the inner ring airbags being disposed in the middle of both ends of the airbag seat cushion, a heating component being disposed inside the airbag seat cushion, a heart rate monitoring component being disposed at the rear of the interior of the airbag seat cushion, and an air pump being included, the air outlet of the air pump being connected to several of the inner ring airbags via a pipe, a controller being fixedly installed at the rear of the interior of the airbag seat cushion, the air pump being electrically connected to the controller, the controller including a wireless transmission module and a data processing module, a pressure monitoring component being disposed on the inner ring airbag, the pressure monitoring component being electrically connected to the controller, and the pressure monitoring component being monitored by the controller, the controller controlling the air pump based on the data from the pressure monitoring component.

[0006] As a further embodiment of the present invention, the airbag seat cushion includes a base plate and a sewn fabric. The base plate is a rigid structure, and the sewn fabric is disposed on the upper surface of the base plate. The sewn fabric is fixed to the upper surface of the base plate by hot melt adhesive. The sewn fabric wraps around the airbag body, and the inner airbag is made of soft fabric.

[0007] As a further embodiment of the present invention, the inner ring airbag includes an adjustable airbag, which is arranged in multiple groups. The adjustable airbags in several groups are arranged in a ring array and are distributed outward at equal intervals. A connecting tube connects the several adjustable airbags in one group.

[0008] As a further embodiment of the present invention, the pressure monitoring component includes a gas pressure sensor, which is fixedly mounted on the adjustable airbag and electrically connected to the controller.

[0009] As a further embodiment of the present invention, the heating assembly includes a heating wire, which is disposed on the upper surface of the base plate at a position corresponding to the two sets of adjustable airbags, and an isolation strip is provided on the upper surface of the base plate at the outer side of the heating wire.

[0010] As a further embodiment of the present invention, the heart rate monitoring component includes a millimeter-wave radar, which is symmetrically arranged on the rear upper surface of the base plate, and the millimeter-wave radar is electrically connected to the controller.

[0013] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows: 1. This invention uses a gas pressure sensor to monitor the air pressure data in several adjustable airbags at different locations and transmits the data to a data processing module. The data processing module can calculate the air pressure and other data inside the airbag bodies. When the average pressure difference between the corresponding areas of the airbag bodies on the left and right sides of the human body exceeds a set threshold, the controller controls the air pump to inflate the airbag body on the low-pressure side. The operation of the air pump can inflate several adjustable airbags in a group, raising the height of one side of the human body. At the same time, the individual opening of the valve can deflate several adjustable airbags in a group, realizing the inflation and deflation of several adjustable airbags in a group. The inner ring airbags at both ends of the airbag seat cushion can be balanced and adjusted to achieve uniform force on the left and right sides of the human body, thereby correcting the sitting posture. 2. This invention achieves the heating function of the airbag seat cushion by controlling the heating wire to be energized and heating it, and by protecting the area of ​​the heating wire with an isolation strip. At the same time, the use of millimeter-wave radar can realize real-time heart rate monitoring of the human body, thus realizing the multi-functionality of this device.

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0018] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Please see the appendix Figure 1 - Appendix Figure 4An airbag seat cushion with pressure and monitoring sensors includes an airbag seat cushion 1. Airbag bodies 2 are equidistantly installed inside the airbag seat cushion 1. The airbag bodies 2 are made of heat-resistant rubber (such as fluororubber) and are wrapped with a fiber reinforcement layer. The airbag bodies 2 include outer ring airbags 21 and inner ring airbags 22. The outer ring airbags 21 are located around both ends of the airbag seat cushion 1, and the inner ring airbags 22 are located at the center of both ends of the airbag seat cushion 1. The inner ring airbags 22 include adjustable airbags 221. Multiple groups of adjustable airbags 221 are arranged in a circular array and are equidistantly distributed outwards. A network is established between the adjustable airbags 221 in each group. The airbag cushion 1 has a heating component 3 inside, a heart rate monitoring component 4 inside and at the rear of the airbag cushion 1, and an air pump 5. The air pump 5 is electrically connected to an external power source via a wire. The air outlet of the air pump 5 is connected to several inner ring airbags 22 via a pipe. The air outlet of the air pump 5 has multiple air tubes, which are integrally formed inside the base plate 11. Each air tube is connected to a connecting pipe 222 in a set of adjustable airbags 221, and each air tube is equipped with a valve to close or open a single air tube. A controller 6 is fixedly installed inside and at the rear of the airbag cushion 1. The air pump 5 is electrically connected to the controller 6. The controller 6 includes a wireless transmission module 61 and a data processing module 62. A pressure monitoring component 7 is installed on the inner airbag 22. The pressure monitoring component 7 is electrically connected to the controller 6 and is monitored by the controller 6. The controller 6 controls the air pump 5 based on the data from the pressure monitoring component 7. The wireless transmission module 61 can wirelessly transmit data such as the detection data from the heart rate monitoring component 4, the working status of the air pump 5, and the air pressure inside the airbag body 2 to the display component 8. Simultaneously, the data processing module 62 can calculate the air pressure data inside several airbag bodies 2. When the average pressure difference between the corresponding areas of the airbag bodies 2 on the left and right sides of the body exceeds a set threshold (e.g., 10), the data processing module can calculate the pressure. When the pressure difference is between 20% and 20%, the controller 6 controls the operation of the air pump 5 to inflate the airbag body 2 on the low-pressure side. The valve connects and closes the connecting pipe 222 of a group of adjustable airbags 221. The operation of the air pump 5 can inflate several adjustable airbags 221 in a group until the pressure difference returns to within the threshold, which can raise the height of one side of the human body. At the same time, the individual opening of the valve can deflate several adjustable airbags 221 in a group, realizing the inflation and deflation of several adjustable airbags 221 in a group. The inner ring airbags 22 at both ends of the airbag seat cushion 1 can be balanced and adjusted to achieve uniform force on the left and right sides of the human body, thereby achieving the effect of correcting sitting posture.

[0020] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 The airbag seat cushion 1 includes a base plate 11 and a sewn fabric 12. The base plate 11 is a rigid structure. The sewn fabric 12 is disposed on the upper surface of the base plate 11 and is fixed to the upper surface of the base plate 11 by hot melt adhesive. The sewn fabric 12 is disposed to wrap the airbag body 2. The inner ring airbag 22 is made of soft fabric.

[0021] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 The pressure monitoring component 7 includes a gas pressure sensor 71, which is fixedly mounted on the adjustable airbag 221 and electrically connected to the controller 6.

[0022] In practice, the gas pressure sensor 71 detects the air pressure in the adjustable airbags 221 and transmits the air pressure data of several adjustable airbags 221 to the data processing module 62 of the controller 6 via wired transmission. When a person sits on the device, the gas pressure sensor 71 transmits the air pressure data of several adjustable airbags 221 at different positions to the data processing module 62. The data processing module 62 summarizes the air pressure data of the adjustable airbags 221 at different positions. Each ring of adjustable airbags 221 is marked as A1, A2, A3..., B1, B2, B3..., and C1, C2, C3, etc., where A, B, and C represent adjustable airbags 221 at different ring positions. An algorithm is used to process each... The average air pressure of several adjustable airbags 221 in one circle is calculated using P(average) = (A1, A2, A3....) / M, where M is the number of adjustable airbags 221 in each circle. Simultaneously, the air pressure values ​​of adjustable airbags 221 at different positions are transmitted to the display component 8 via the wireless transmission module 61. The air pressure data of adjustable airbags 221 at different positions are displayed in a combination of text and graphics to represent the force-bearing areas of adjustable airbags 221 at different positions. Force analysis can be performed on the left and right sides of the human body to realize the force calculation of the left and right sides of the human body in a sitting posture. The controller 6 is also equipped with a timer to analyze the air pressure data of adjustable airbags 221 at specified time periods and transmit the data to the display component 8 at regular intervals.

[0023] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 The heating component 3 includes a heating wire 31, which is disposed on the upper surface of the base plate 11 at a position corresponding to the position between the two sets of adjustable airbags 221. An isolation strip 32 is provided on the upper surface of the base plate 11 at the outer side of the heating wire 31.

[0024] In practice, the operation of the heating component 3 is controlled by a display component 8 such as a mobile phone or tablet. The display component 8 transmits the control signal to the controller 6 through the wireless transmission module 61. The control switch in the controller 6 enables the heating wire 31 to be energized and heated, and the area of ​​the heating wire 31 is protected by the isolation strip 32, thereby realizing the heating function of the airbag seat cushion 1.

[0025] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 The heart rate monitoring component 4 includes a millimeter-wave radar 41, which is symmetrically arranged on the upper rear surface of the base plate 11. The millimeter-wave radar 41 is electrically connected to the controller 6. The radar signal of the millimeter-wave radar 41 is processed by a filtering algorithm, which can effectively distinguish between micro-heartbeats and macro-human movements. The heart rate monitoring accuracy can reach ±2 beats / minute in a sitting environment.

[0026] In practice, the millimeter-wave radar 41 emits continuous frequency modulated waves (FMCW) or pulse waves in the 24GHz or 60GHz band, penetrating clothing and illuminating the inside of the human body. The periodic micro-movements (amplitude of about 0.1-1mm) generated by the blood vessels are reflected back as phase changes (Doppler shift) caused by these micro-movements. Accelerometer data in the millimeter-wave radar 41 is used to distinguish between body movement and heartbeat vibrations. Phase information is extracted through arctangent operation and converted into displacement change. The algorithm formula is as follows: Δd(t)=(λ / 4π)*ΔΦ(t), where λ is the wavelength and ΔΦ(t) is the phase difference. The preprocessed signal is automatically peak identified (such as by the Pan-Tompkins algorithm), the interval between adjacent R waves is calculated and converted into heart rate, and real-time heart rate monitoring of the human body is achieved.

[0027] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 The controller 6 is equipped with an external power supply connection.

[0028] In practice, the controller 6 and the entire device can be powered by an external power supply to achieve continuous operation.

[0029] As one technical optimization of the present invention, please refer to the appendix. Figure 1 - Appendix Figure 4 It also includes a display component 8, which can be a mobile phone or tablet or other device. The display component 8 is used to receive and display pressure distribution and heart rate data, and has a user interface for users to manually control heating and pressure adjustment functions.

[0030] In practice, an app can be programmed and set up on mobile phones or tablets to display various data, so as to clearly display the data and make it convenient to use.

[0031] Working principle: When a person sits on this device, the gas pressure sensor 71 monitors the air pressure data in several adjustable airbags 221 at different positions and transmits the data to the data processing module 62. The data processing module 62 calculates the air pressure and other data inside the airbag bodies 2. When the average pressure difference between the corresponding areas on the left and right sides of the person exceeds a set threshold (e.g., 10% to 20%), the controller 6 controls the air pump 5 to operate and inflate the airbag on the low-pressure side of the airbag body 2. The pressure difference is then controlled by the valve to adjust the pressure of the airbag. The connection and closure of the connecting pipe 222 of the adjustable airbag 221 group can be achieved by the operation of the air pump 5 to inflate several adjustable airbags 221 in a group until the pressure difference returns to within the threshold, which can raise the height of one side of the human body. At the same time, the individual opening of the valve can be used to deflate several adjustable airbags 221 in a group, realizing the inflation and deflation of several adjustable airbags 221 in a group. The inner ring airbags 22 at both ends of the airbag seat cushion 1 can be balanced and adjusted to achieve uniform force on the left and right sides of the human body, thereby achieving the effect of correcting sitting posture. The operation of the heating component 3 is controlled by a display component 8 such as a mobile phone or tablet. The display component 8 transmits the control signal to the controller 6 through the wireless transmission module 61. The control switch in the controller 6 realizes the power supply and heating of the heating wire 31, and protects the area of ​​the heating wire 31 through the isolation strip 32, so as to realize the heating function of the airbag seat cushion 1. The use of millimeter wave radar 41 can realize real-time heart rate monitoring of the human body.
