Description
Technical Field
The invention relates to a sitting posture corrector for eyesight of teenagers, in particular to an intelligent adjustment and timing integrated sitting posture corrector, and belongs to the field of mechanical design, manufacture and automation.
Background
With the rapid development of society, the myopia rate of teenagers increases rapidly, and most of them are caused by bad habits of sitting posture errors and long-time eye use. Teachers have no specific requirements when correcting sitting postures of students, lack of standard standards, are poor in operability, and enable crystalline lenses to be in an exhausted state even if eyes are used continuously. Most of the existing orthotics in the market are mechanical devices, the comfort level is poor, children are easy to rely on the mind, the sitting posture of the students is mainly corrected, another key factor influencing the eyesight is ignored, and the eyes are used for a long time. Therefore, the intelligent adjustment and timing integrated sitting posture vision corrector is manufactured according to a physical principle, combines the physical characteristics of students, utilizes the pressure sensor to sense pressure, can bring pressure signal changes due to sitting posture changes, starts the buzzer through the control circuit according to the pressure signals to remind the students of the sitting posture, is designed with the timing device to prompt the learning time of the students, controls the eye using time of the students to be about 40 minutes, and adjusts the sitting posture of the students and plays a role in adjusting vision.
Disclosure of Invention
(1) Follow the "three one" pithy formula: eyes are one ruler away from the book, chest is one fist away from the desktop, fingers are one foot away from the pen point. The distance-adjustable flexible device is designed, so that students can only sit in the seat, adjust sitting postures according to the pithy formula and fix the device, and the effect of keeping standard sitting postures for a long time can be achieved.
(2) Classical conditioned reflex theory (also known as pavlov conditioned reflex): refers to the multiple association of one stimulus with another unconditional stimulus with reward or punishment that allows an individual to learn to elicit a conditional response that resembles an unconditional response when the stimulus is presented alone. The design utilizes an external orthotic device to stimulate the incorrect sitting posture of a student multiple times, thereby fixing the body in the same correct position for a long time, forming a conditioned reflex similar to an unconditional response over time, and still maintaining a good sitting posture after the device is removed.
(3) The pressure sensor is used for sensing the pressure signal, and according to a specified pressure value of 5kg (about 20-30% of the total pressure value), the pressure signal is converted into an output electric signal when the pressure signal exceeds the specified pressure value, and the output electric signal is represented as vibration, so that the reminding effect is achieved.
(4) As the eye adjusting ability of the teenagers is strong, the teenagers can clearly see characters and objects in a short distance and even in front of the eyes, so that the teenagers are unconsciously and often in a short-distance learning state, the eyes are continuously adjusted in height, and the formation of myopia is promoted. The literature shows that the vision of students is seriously influenced by using eyes for a long time, and the general learning time and the continuous eye using time are not suitable to exceed 40 minutes. Therefore, the timing relay controls the indicator lamp to play a role in automatic timing.
