Background

In recent years, more and more myopia patients have obvious trend towards juvenile, and many children still in the primary school stage begin to have myopia, and the proportion of myopia in the primary school students and the high school students is higher. In the face of this phenomenon, the public generally thinks that it is caused by using electronic products for a long time, such as watching television, watching tablet, and watching mobile phone for a long time. However, in the electronic age, the dissemination of information and knowledge is mostly realized by electronic products, and even schools adopt video teaching and electronic teaching. When the mobile phone leaves a television, a tablet or a mobile phone, the user can hardly know the outside things conveniently and even can be isolated from the society. Then, really just as the electronic products generally accepted by the general public tend to cause myopia? In the era without electronic products, many old scholars also have eye diseases of myopia or hypermetropia, which are caused by what?

It has been found that the root cause of myopia or hyperopia of eyes is because eyes watch objects at a fixed distance for a long time, or the distance from an electronic product or book to eyes is basically in a certain range when the electronic product or book is watched for a long time, so that eye muscles and eye membrane tissues are kept in a basically same state for a long time, and the eye muscles and eye membrane tissues are memorized and basically fixed in the state. When the eyes look at a far or a near object, the eye muscles and eye membrane tissues cannot or are difficult to contract or stretch to a certain state, the eyes have the problem that the object cannot be seen clearly, and finally, myopia or hypermetropia is caused.

Detailed Description

The first embodiment of the notebook computer with eyesight protection function of the invention: as shown in fig. 1-3, the display device comprises a main body 10 and a display 11 rotatably assembled with the main body 10, wherein the display 11 comprises a mounting structure and a screen mounted in the mounting structure.

Specifically, the main body 10 is provided with two rotation shafts on one side in the length direction, and the two rotation shafts are respectively arranged near two ends in the width direction. The display 11 is sleeved outside the rotating assembly shaft through the display seat sleeve 110 and rotates around the rotating assembly shaft, so that the display and the host machine are opened and buckled. The rotating assembly shaft at one end of the two rotating assembly shafts is a fixed shaft, and the fixed shaft and the corresponding seat cover are sleeved in a hollow manner, so that the rotating friction is small, and the relative rotation is convenient. The micro speed reducing motor 2 is arranged at the other end position in the main machine, the output shaft 20 of the micro speed reducing motor 2 is connected with the friction rotating shaft 21, the friction rotating shaft 21 forms a rotating assembly shaft at the end of the main machine, and the friction rotating shaft 21 is in friction fit with the corresponding display seat cover 110 on the display 11, so that the display 11 is ensured to rotate relative to the main machine 10 under the driving of the friction force of the friction rotating shaft 21. Of course, in other embodiments, the friction rotating shaft may be directly a segment of the output shaft of the miniature speed reduction motor.

The control unit which is connected with the miniature speed reducing motor in a control mode is arranged in the host 10, when the notebook computer is used, the control unit controls the miniature speed reducing motor to rotate and drives the display to swing back and forth relative to the host, so that the change of the distance between eyes of a user and the display is realized, the continuous adjustment of the display can drive eye muscles and eye membrane tissues of the user to stretch and contract, the eye muscles and the eye membrane tissues move, the situation that the eye muscles and the eye membrane tissues are kept in the basically same state for a long time is avoided, and myopia or hypermetropia is prevented or relieved finally.

Of course, the linear velocity of the reciprocating swing of the display driven by the miniature speed reduction motor is not more than 200mm/s, so that the display is convenient for a viewer to adapt, and the specific swing velocity can be set according to actual needs. Furthermore, the single-pass swing angle of the display cannot be too large, preferably within 60 °, such as 30 °, 45 °, etc. The reciprocating swing stroke of the display comprises an outward stroke and a return stroke, a plurality of pause positions are arranged at the reciprocating swing retracing position and on the stroke track of the outward stroke and the return stroke, for example, in the swing stroke process of being far away from and close to the host, the pause is 3-6 times, the pause time is 3-10 s each time, and the pause is stopped for a period of time at the end positions of the outward stroke and the return stroke. Of course, the specific pause time of the display at the pause position can be freely set, so that the flexibility of adjusting the eyes of the viewer can be improved.

In a more humanized design, when the display is subjected to external rotation resistance or the display 11 is manually pulled in the using process, the external resistance or the acting force of the manual pulling can force the friction rotating shaft 21 and the display seat sleeve 110 to slip and rotate relatively, so that the damage of the miniature speed reduction motor is avoided.

In this embodiment, one of the two rotation assembly shafts is set as the fixed shaft, considering that the two miniature speed reduction motors are complex in structure, high in cost and high in control difficulty, and certainly, if one miniature speed reduction motor is not enough to drive the display to rotate in other embodiments, the two miniature speed reduction motors can be arranged on the host machine, and output shafts of the two miniature speed reduction motors are respectively used as the rotation assembly shafts for friction fit of the display seat sleeve. Even in other embodiments, the main machine can be rotationally matched with the seat cover of the display through more than three rotating assembly shafts, and the number of the miniature speed reducing motors can be adjusted according to actual needs.

More optimally, the host is provided with a dynamic/static operation key which controls the rotation and the stop of the miniature speed reducing motor, and when the display does not need to rotate automatically, the dynamic/static operation key can be pressed to close the miniature speed reducing motor; when the display needs to swing back and forth, the movable/static operation key can be pressed to start the miniature speed reducing motor; of course, in other embodiments, a two-position switch may also be adopted, and the two positions of the switch correspond to the starting state and the stopping state of the micro speed reduction motor respectively; certainly, further, the switch can be a switch with more than three positions, and other positions beyond the two positions respectively control the rotation speed of the miniature speed reduction motor, so that the multi-gear adjustment of the rotation speed of the display is realized.

In addition, when the user finishes using and shuts down, the control unit controls the micro speed reduction motor to drive the display to be closed, for example, a proximity switch is arranged on the host, when the shutdown program is carried out, the micro speed reduction motor drives the display to rotate towards the closing direction until the proximity switch gives a control unit signal, and the control unit controls the micro speed reduction motor to shut down.

The notebook computer of the present invention is not limited to the above-mentioned embodiments, and in other embodiments, the driving device for driving the display to swing may be disposed in the display, for example, when the power mechanism of the driving device is a speed reducing motor, a fixed portion engaged with the output end of the speed reducing motor is disposed in the main body, and in this case, the driving device is disposed on the movable portion, which is different from the conventional mechanism.
