Problems solved by technology

However, as the work intensity increases and the rest time shortens, the human muscles and spine are prone to static fatigue, and produce discomfort symptoms such as low back pain and lumbar disc herniation, which not only cause harm to health, but also affect work. efficiency
In addition, sitting on a chair for a long time to work and study, incorrect sitting posture is more likely to cause fatigue, damage to the spine and muscles, and cause abnormal growth of the back
[0003] Most of the existing office chairs can perform some simple adjustments, but they can only adjust the height of the seat and the angle of the backrest, and cannot actively remind people in time when the sitting posture is incorrect, so as to realize the function of correcting the sitting posture

Embodiment 1

[0018] like figure 1 As shown, a sitting posture correction chair comprises a seat 1 and a backrest 2, the seat 1 is provided with a pressure sensor array 3, and the pressure sensor array 3 monitors the position of the center of gravity of the buttocks; the backrest 2 is provided with an infrared sensor array 4, and the infrared sensor The array 4 monitors the distance between the back and the backrest 2, the side of the backrest 2 is provided with a buzzer 5, and the inside of the backrest 2 is provided with a microprocessor and a power supply, and the microprocessor is respectively connected with the pressure sensor array 3, the infrared sensor array 4, and the buzzer 5 electrical connection with the power supply.

[0019] The number of pressure sensors in the pressure sensor array 3 is 4, and the 4 pressure sensors are respectively installed on the upper, lower, left, and right sides of the seat 1, and jointly monitor the position of the center of gravity of the buttocks fr...

Embodiment 2

[0025] combine figure 1 and figure 2 , explaining how it works.

[0026] When the person does not sit on the seat 1, the pressure sensor array 3 and the infrared sensor array 4 do not work, and the system is in a standby state to save power consumption. When a person sits on the seat 1, the pressure sensor array 3 feels the pressure on the buttocks, and the four pressure sensors deform respectively to monitor the center of gravity of the buttocks in real time, and wake up the infrared sensor array 4 at the same time, and the upper and lower infrared sensors monitor the back in real time The distance from the backrest 2, the microprocessor continuously receives the monitoring values ​​of the pressure sensor array 3 and the infrared sensor array 4, and compares it with the preset effective range value of the center of gravity position and the effective range value of the back-back distance, if it is determined to be within the effective range If it is judged to be out of the ...

Abstract

The invention provides a sitting posture correcting chair which comprises a seat and a backrest. A pressure sensor array is arranged on the seat and monitors the gravity center position of a hip. An infrared sensor array is arranged on the backrest and monitors the distance between a back and the backrest. A buzzer is arranged on the side face of the backrest. A microprocessor and a power supply are arranged in the backrest. The microprocessor is electrically connected with the pressure sensor array, the infrared sensor array, the buzzer and the power supply. By arranging the pressure sensor array on the seat and the infrared sensor array on the backrest, the gravity center of the human hip and the distance between the back and the backrest are monitored in real time; when a sitting posture is not correct, the sitting posture correcting chair actively reminds people to correct the sitting posture in time, the health of the spine, waist and back is protected, work efficiency is improved, and a good sitting posture habit is easily developed.

Description

technical field [0001] The invention relates to the technical field of medical care, in particular to a posture correction chair. Background technique [0002] With the rapid development of computer information technology, more and more people need to study and work in a sitting position. People spend more and more time sitting on chairs. Most people spend at least 20 years in chairs in their lives. of. However, as the work intensity increases and the rest time shortens, the human muscles and spine are prone to static fatigue, and produce discomfort symptoms such as low back pain and lumbar disc herniation, which not only cause harm to health, but also affect work. efficiency. In addition, sitting on a chair for a long time to work and study, incorrect sitting posture is more likely to cause fatigue, damage to the spine and muscles, and cause abnormal growth of the back. [0003] Most of the existing office chairs can perform some simple adjustments, but they can only adj...
