[0041] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further explained in detail.
[0042] As Figure 1 The utility model discloses a kind of myopia-preventing electrochromic glasses, including glasses frame 1, gyroscope 2, range sensor, control panel 3, battery assembly 4, two glasses legs 5 and two electrochromic lenses 6;
[0043] The glasses leg 5 is connected on the glasses frame 1;
[0044] The control panel 3 is installed in the glasses leg 5;
[0045] The battery assembly 4 is installed in the glasses leg 5 and is connected with the control panel 3, and the battery assembly 4 is used to power supply the control panel 3;
[0046] The gyroscope 2 is directly or indirectly connected on the glasses frame 1 and is connected with the control panel 3, and the gyroscope 2 is used to detect the inclination angle information when the glasses frame 1 is worn on the head of user and send to the control panel 3;
[0047] The range sensor is directly or indirectly connected on the glasses frame 1 and is connected with the control panel 3, and the range sensor is used to measure the distance information between glasses frame 1 and desktop and send to the control panel 3;
[0048] The electrochromic lens 6 is installed in the frame 1, and is connected to the control board 3 through a flexible circuit board 7. The control board 3 is used to control the electrochromic lens 6 to be electrified or de-energized according to the inclination angle information of the frame 1 and the distance information between the frame 1 and the table, so as to change the color of the electrochromic lens 6. Specifically, the inclination angle of the frame 1 is the inclination angle of the user's head, which can reflect the spatial posture of the user's head; the distance between the frame 1 and the table is the distance between the user's eyes and the table, which can reflect the user's eye distance. Further specifically, the gyroscope 2 can detect the left-right inclination angle θ1 and the pitch inclination angle θ2 of the frame 1 and send them to the control board 3, and the distance sensor can measure the distance S between the frame 1 and the table and send it to the control board 3. When any one of θ1 and θ2 exceeds the set range, it means that the user's sitting posture is not correct, and there is a posture of crooked neck and tilted head. When S exceeds the set range, it means that the user's eyes are too close to the table. Therefore, when any one of θ1, θ2 and S exceeds the set range, the output end of the control board 3 outputs 1.2V voltage to the electrochromic lens 6 through the flexible circuit board 7, so as to make the electrochromic lens 6 electrified and the color darkened, so that the user cannot see the reading target on the table, and thus the user can be reminded to adjust his / her own sitting posture and eye distance in time, and the effect of preventing myopia is better. When θ1, θ2 and S are all within the set range, the output end of the control board 3 stops outputting voltage, the electrochromic lens 6 is de-energized and faded, and the user's line of sight is restored to be clear and can continue to read and study. Therefore, not only the distance between the frame 1 and the table can be measured by the distance sensor to correct the eye distance, but also the inclination angle of the frame 1 can be detected by the gyroscope 2 to correct the bad reading posture of crooked neck and tilted head, so as to improve the effect of preventing myopia. Further specifically, as shown in Figure 6 From the perspective of the user's front or rear plane, the angle between the gyroscope 2 and the vertical axis is θ1, and when the user's head is straight, θ1 is 0°, and when the user's head or body is inclined left or right, θ1 > 0°. As shown in Figure 7As shown, the angle between the gyroscope 2 and the horizontal axis is θ2 from the user side, which is 0° when the user looks straight ahead and >0° when the user looks up or down. In this embodiment, when θ1≤3° and θ2≤45° and S≥33.3 cm, the user is in a correct sitting posture, the control board 3 controls the electrochromic lens 6 to remain in a non-powered state, the electrochromic lens 6 does not change color, and the user can continue to learn in the current sitting posture. When θ1>3° or θ2>45° or S<33.3 cm is detected, the control board 3 controls the electrochromic lens 6 to be powered, and the transmittance of the electrochromic lens 6 decreases and the color becomes darker, at which time the user cannot see the reading target on the desktop, thereby prompting the user to adjust the sitting posture until θ1≤3° and θ2≤45° and S≥33.3 cm are restored, the control board 3 controls the electrochromic lens 6 to be powered, the transmittance of the electrochromic lens 6 returns to 90% and the color becomes lighter, and the user's line of sight returns to clear to continue reading and learning. The myopia-preventing electrochromic glasses of the present application have no limitation on application scenarios, can quickly remind the user to adjust the sitting posture, maintain a reasonable eye distance, develop good sitting habits, effectively prevent myopia, and have a promising market application prospect.

[0063] The first end of the flexible circuit board 7 is directly or indirectly connected with the control board 3, and the second end of the flexible circuit board 7 is electrically connected with the upper half of the electrode 15 and the lower half of the electrode 16 in the electrochromic lens 6 respectively. Specifically, by arranging the upper half of the electrode 15 and the lower half of the electrode 16, the speed of the electrochromic solution 13 changing color can be improved, and the response of the electrochromic lens 6 can be improved, so that the transmittance can be reduced to 3% within 1s when powered on, and the transmittance can be restored to 90% within 3s when powered off.
[0064] In this embodiment, the first end of the flexible circuit board 7 can be directly connected with the control board 3, and the output end of the control board 3 can output 1.2V voltage to the electrochromic lens 6 through the flexible circuit board 7. Of course, in some embodiments, the first end of the flexible circuit board 7 can also be connected with the control board 3 through a wire.
[0065] As shown in Figures 2 to 5 The first connecting part 17 is arranged on the front conductive glass 10, and the second connecting part 18 coincides with the first connecting part 17 on the rear conductive glass 11;
[0066] One end of the upper half of the electrode 15 extends to the first connecting part 17;
[0067] One end of the lower half of the electrode 16 extends to the second connecting part 18;
[0068] The second end of the flexible circuit board 7 is inserted between the first connecting part 17 and the second connecting part 18 and the flexible circuit board 7 is electrically connected with the upper half-circle electrode 15 and the lower half-circle electrode 16 respectively; specifically, the second end of the flexible circuit board 7 has a first gold finger port and a second gold finger port, the first gold finger port is bonded with the upper half-circle electrode 15 through conductive silver paste, and the second gold finger port is bonded with the lower half-circle electrode 16 through conductive silver paste. Further specifically, the upper half-circle electrode 15 can be plated on the conductive surface of the front conductive glass 10 by sputtering, and the lower half-circle electrode 16 can be plated on the conductive surface of the rear conductive glass 11 by sputtering.
[0069] As shown in Figures 2 to 5 , the material of the upper half-circle electrode 15 and the lower half-circle electrode 16 is copper target material;

[0071] The thickness of the front conductive glass 10 and the rear conductive glass 11 is 0.55mm.

[0073] In summary, the inclination angle of the mirror frame 1 is the inclination angle of the user's head, which can reflect the spatial posture of the user's head; the distance between the mirror frame 1 and the desktop is the distance between the user's eyes and the desktop, which can reflect the user's eye distance. The gyroscope 2 can detect the left-right inclination angle θ1 and the pitch inclination angle θ2 of the mirror frame 1 and send them to the control board 3, and the distance measuring sensor can measure the distance S between the mirror frame 1 and the desktop and send it to the control board 3. When any of θ1 and θ2 exceeds the set range, it means that the user's sitting posture is not correct, and there is a posture of crooked neck and tilted head, and when S exceeds the set range, it means that the user's eyes are too close to the desktop. Therefore, when any of θ1, θ2 and S exceeds the set range, the output end of the control board 3 outputs a 1.2V voltage to the electrochromic lens 6 through the flexible circuit board 7, and then the electrochromic lens 6 becomes dark after being powered on, so that the user cannot see the reading target on the desktop, and thus the user can be reminded to adjust his own sitting posture and eye distance in time, and has a better effect of preventing myopia. When θ1, θ2 and S are all within the set range, the output end of the control board 3 stops outputting voltage, and the electrochromic lens 6 fades and becomes lighter after being powered off, and the user's line of sight restores clear and can continue to read and learn. Therefore, not only can the distance measuring sensor measure the distance between the mirror frame 1 and the desktop to correct the eye distance, but also the gyroscope 2 can detect the inclination angle of the mirror frame 1 to correct the bad reading posture of crooked neck and tilted head, and thus the effect of preventing myopia can be improved.
