Problems solved by technology
In the same way, a good sitting posture not only protects the eyes, but also protects the development of the waist. Many primary school students have improper sitting posture and bend their backs while sitting on chairs. This is not good for physical development, causing spinal curvature and affecting the normal development of the spine.
If you bend over and write on the table, this wrong sitting posture is extremely harmful to your eyesight, and it is easy to cause myopia, with serious consequences
When elementary school students are formally attending classes, due to the constraints of classroom discipline, the sitting posture is easy to be corrected. However, if there is no supervision, the incorrect sitting posture is often not corrected in time. It becomes a habit over time, resulting in curvature of the spine or myopia. It is also unrealistic for parents or teachers to monitor their body position or sitting posture at all times

The invention discloses a multifunctional school badge. The multifunctional school badge comprises a school badge casing, a logo printed on the surface of the casing, a power supply circuit, a reminding circuit and a position switch, wherein the power supply circuit, the reminding circuit and the position switch are mounted in the casing; the position switch is connected between the power supply circuit and the reminding circuit. According to the multifunctional school badge, magnetic force lines of permanent magnets are cut by coils, so that motional electromotive force is produced, and the self-powering effect is realized under the premise that extra energy from outside is not required. The reminding circuit is controlled by the position switch, and the position switch produces sound to remind a user when detecting that the position of the user is over a specified angle.
Description
technical field [0001] The invention relates to the technical field of badges, in particular to a school badge which can give reminders when the body position is incorrect. Background technique [0002] The school badge is a certificate worn by students, with the name of the school printed on it, showing the wearer's affiliation. Since the school badge appeared, this simple display function has not changed for more than a hundred years. [0003] On the other hand, students are in the rapid stage of physical growth and development, especially in elementary school. Correct standing and sitting postures have a great impact on the growth and development of their bones. "Sitting like a bell and standing like a pine" emphasized in traditional Chinese culture is also the expectation of millions of parents for the correct posture of their children. However, due to poor self-discipline ability, primary school students often cannot maintain correct posture. [0004] The student's po...
