[0035] The intelligent sitting posture corrector with adaptive sitting posture adjustment further includes a sensor module, which is used to detect the pressure distribution of the user's sitting posture, judge whether there is body tilt or forward lean, monitor the bending angle of the spine and the body tilt state. The sensor module includes a pressure sensor 131 and a gyroscope 271. The gyroscope 271 is installed inside the backrest body 27, and the installation position corresponds to the human lumbar region, usually located in the middle and lower part of the backrest body 27. The lumbar spine is the area that bears the most pressure in the sitting posture and is also the part where the bending angle of the spine changes most significantly. Installing it here can accurately monitor the tilt and bending state of the user's waist, helping to judge whether there is hunchback or excessive forward lean. The pressure sensor 131 is a piezoelectric film sensor. The pressure sensors 131 are distributed in a matrix on the inner surfaces of the seat cushion 13 and the support plate body 31 to monitor the pressure distribution of the user's sitting posture. Specifically, airbags 132 are provided inside both the seat cushion 13 and the support plate body 31. The airbags 132 push the pressure sensors 131 to contact the inner surfaces of the seat cushion 13 or the support plate body 31. An air inlet and outlet valve 1321 is provided below the airbag 132. After the user contacts the surface of the seat cushion 13 or the support plate body 31, the pressure is transmitted to the pressure sensor 131. The airbags 132 in the seat cushion 13 are distributed in a columnar structure array. Ventilation holes 133 are provided on the surface of the seat cushion 13. The columnar structure can improve the overall ventilation effect of the seat cushion 13. Pressure sensors 131 are also arranged on one side edge of the seat cushion 13 close to the support plate assembly 3 to monitor the distance between the calf and the seat cushion 13. The airbag 132 in the support plate body 31 is a whole structure. The airbag 132 pushes the pressure sensor 131 to contact the inner wall of the support plate body 31. The pressure sensors 131 are also distributed on the edge of the support plate body 31. When the support plate body 31 supports the user's shoulders, the upper edge of the support plate body 31 supports the user's chin.

[0036] The intelligent sitting posture correction with adaptive sitting posture adjustment further includes a control module and a feedback module. The control module is responsible for processing sensor data, running a sitting posture recognition algorithm and an adaptive adjustment algorithm, analyzing sensor data in real time based on a machine learning model, judging whether the sitting posture is standard, dynamically adjusting the height, angle and support strength of the seat 1 according to the user's body data and sitting posture habits, and storing the user's sitting posture data and personalized settings. When the feedback module detects a bad sitting posture, it reminds the user to change the sitting posture through vibration. The feedback module includes several vibration motors 272. The vibration motors 272 are distributed on the back of the backrest body 27, the bottom of the seat cushion 13 and the back of the support plate body 31, and remind the user to adjust the posture through vibration.

[0037] Working process: The user sits on seat 1, turns on the power, and the system starts. The user inputs personalized data such as height and weight through a remote control or a mobile phone APP. The system automatically adjusts the height of seat 1, the angle of backrest assembly 2, and the position of support plate assembly 3 to provide preliminary support. When the user needs to work or study at a desk, the user controls support plate assembly 3 to expand. The support plate body 31 fits against the user's shoulders, and the backrest body 27 fits against the user's back. When the user does not need to work at a desk, the user leans against the backrest body 27, and support plate assembly 3 is folded. The support plate body 31 is retracted to support the user's calf. The pressure sensors 131 distributed on the inner surfaces of the seat cushion 13 and the support plate body 31 monitor the pressure distribution of the user's sitting posture in real time. The gyroscope 271 installed in the lumbar region of the backrest body 27 monitors the bending angle of the spine and the tilting state of the body in real time. The sensor module transmits the collected data to the control module. The control module runs a sitting posture recognition algorithm, analyzes the sensor data based on a machine learning model, and determines whether the user's sitting posture is standard. If the pressure sensors 131 detect uneven pressure distribution on the buttocks, or the gyroscope 271 detects an excessive bending angle in the lumbar region, the control module starts an adaptive adjustment algorithm to dynamically adjust the positions and angles of seat 1, backrest assembly 2, and support plate assembly 3. The height of seat 1 is adjusted through the lifting device 112 to ensure that the user's legs are at a 90-degree angle to the ground. The angle of backrest assembly 2 is adjusted through the angle motor 23 to provide optimal lumbar support. The height and angle of the support plate body 31 are adjusted through the first motor 33, the second motor 35, and the third motor 37. If the user does not adjust the sitting posture in time, the feedback module issues a vibration reminder through the vibration motor 272.
