Triggering type intelligent writing sitting posture corrector

Abstract

The invention discloses a triggering type intelligent writing sitting posture corrector. The triggering type intelligent writing sitting posture corrector is characterized in that a correction controlis arranged in a shell, the correction control comprises a piezoelectric triggering component, a control switch, a voltage management chip, an MEMS sensor module, a microprocessor module and a vibration alarm module; the piezoelectric triggering component comprises a piezoelectric ceramic ring and a central shaft inserted into the center of the piezoelectric ceramic ring, one end of the central shaft is vertically fixed on the inner top surface of the shell in a cantilever beam form, the piezoelectric ceramic ring is fixedly connected to the top end of the central shaft through flexible ropes, the piezoelectric ceramic ring is provided with springs along the radius direction, the springs a fixedly connected with the lower portion of the central shaft, and the surface of the piezoelectricceramic ring is provided with a protecting layer and a metal electrode; the MEMS sensor module comprises an MEMS gyroscope and an AD converter which are integrated; the piezoelectric triggering component, the control switch, the voltage management chip, the MEMS sensor module, the microprocessor module and the vibration alarm module are sequentially serially connected. The triggering type intelligent writing sitting posture corrector is simple in structure, convenient to use, environmentally friendly, low in data analysis quantity and objective and accurate in alarm.

Description

technical field [0001] The invention relates to an intelligent wearable device, in particular to a trigger-type intelligent writing posture corrector. Background technique [0002] For primary and middle school students, writing work at the desk for a long time, the correct posture should be guaranteed: the body is straight, the eyes are one foot away from the book, and the chest is one punch away from the table. However, it is usually difficult for primary and middle school students with unsolidified bones and soft bones. Wrong writing sitting posture may cause serious problems such as high and low shoulders, hunched over, scoliosis and even body deformities. The gradual improvement of good sitting posture Cultivation is not only the key to improving learning efficiency and ensuring learning quality, but also plays a vital role in promoting the mental outlook and future development of primary and middle school students. [0003] At present, the corrective products on the m...

However, it is usually difficult for primary and middle school students with unsolidified bones and soft bones. Wrong writing sitting posture may cause serious problems such as high and low shoulders, hunched over, scoliosis and even body deformities. The gradual improvement of good sitting posture Cultivation is not only the key to improving learning efficiency and ensuring learning quality, but also plays a vital role in promoting the mental outlook and future development of primary and middle school students

[0003] At present, the corrective products on the market usually include: ① A support device installed on the desk, which can serve as a reminder when the student's body is in contact with the support. However, this type of product can only be used in a fixed place and has a flexible Poor performance, large space occupation, easy to cause unnecessary bumps and other limitations; ②The strap device can be used to forcibly correct the sitting posture by adjusting the tightness. However, this type of product is not comfortable to wear and is inconvenient to carry; ③ The electronic vibration alarm device collects the acceleration of the user's body in any direction through the acceleration sensor. When the body tilt angle exceeds the preset value, a vibration alarm will appear. However, this type of product usually performs real-time data collection and data analysis during use. And the amount of calculation is large, the power consumption is high, it is easy to generate unnecessary alarm reminders, and it cannot objectively reflect the real situation
