Compared with the prior art, the invention process and principle of the utility model are as follows:
the inventor of the utility model discovers through long-term research: as shown in fig. 1, when a human body is in writing for a long time, the human body changes from a correct writing posture to a non-correct posture, and the non-correct posture in which the head is largely inclined forward as shown in a is not generally observed, but mainly the non-correct posture in which the head is depressed and the spine is curved as shown in B. It is because of this untimely posture that not only causes myopia but also causes kyphosis with prolonged inattention to correct posture. C is the front view angle of B, when the writing posture becomes untimely, the head is inclined towards the side where the pen is not held, for example, the head is inclined towards the left hand when the pen is held by the right hand, and some children even can put the head on the elbow of the left hand.
Referring to fig. 2, when the signal emission direction of the anti-myopia device based on the wireless ranging principle is parallel to the desktop (i.e. perpendicular to the human body), the signal detection area is as shown in C. In the process of changing the writing posture from correct to incorrect, the front-back displacement of the head is small, the requirement on the accuracy of the wireless distance measuring device is high, and otherwise, false detection or missing detection is easy to occur. For example, when the elbow of a person moves, the person is likely to enter the detection area by mistake; when the distance measuring device of the anti-myopia device has consistency deviation, the effect of the anti-myopia device of the left picture is difficult to guarantee.
Referring to fig. 2, in the anti-myopia device based on the wireless distance measuring principle, when the signal emission direction is perpendicular to the desktop (i.e. parallel to the human body), the signal detection area is as shown in D. In the process of changing the writing posture from correct to incorrect, the up-and-down displacement of the head is large. The precision requirement on the wireless distance measuring device is not high, but the myopia prevention device needs to be close to the hand, and the desktop layout of a user is greatly limited. For example, during writing, a slight movement of the elbow may push the anti-myopia device away from a position where accurate detection can be achieved.
The utility model has the advantages that the infrared signal emitting direction (or the light direction) and the vertical line (namely the human body direction) of the desktop are in acute angles through proper structural layout. In the process of changing the writing posture from correct to incorrect, the head is obviously displaced up and down, and the displacement component perpendicular to the signal emission direction is also larger. So the precision requirement on the wireless distance measuring device is not high. Meanwhile, the signal emission direction and the human body direction form a certain included angle, so that the myopia prevention device can be placed at a position far away from the elbow, and the desktop layout of a user is not influenced.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses with the integration of myopia prevention function module in daily work and/or learning tools, be in the wrong position of sitting condition at the user under, can send the reputation and remind, make the user keep the correct position of sitting to play the effect of prevention myopia, be unfavorable for when writing at ambient light, can send the reputation and remind, make the user in time adjust light, thereby play the effect of prevention myopia.
The utility model discloses a student's acting is essential device during class, and is small, portable is applicable to multiple study, work occasion, convenient operation.
