[0003] In the prior art, the vision training mechanism of a vision training instrument generally includes a fixed training light source, and the training light source is generally a semiconductor light-emitting element (including an LED light source generator or a laser generator) fixedly arranged on a circuit board. This type of training light source generally forms a light spot of varying sizes at the fundus of the user, that is, the user can only see a plane of the light spot. This causes the user's eyes to easily become fatigued during the training process, which is not conducive to the training effect. In addition, the fixed light source cannot bring any effect other than stimulation to the trained eye, which results in a relatively simple method and effect of vision training, and the effect that can be achieved is also quite limited.

On the one hand, it is used to make the light finally converge and pass through the second light-transmitting hole. On the other hand, the first light-transmitting hole, cylindrical shape and second light-transmitting hole of the first light source adjustment member and the second light source adjustment member are used to realize the maximum reflection effect of the heat dissipation light, thereby improving the utilization rate of the light source; the lens holder can be used as a mounting member to install the sight mark and the lens at the same time, which has the advantage of convenient assembly.

[0035] Optionally, the light source module further includes:

[0038] Among them, the light emitted by the light-emitting component can be reflected on the inner wall of the light-shielding wall, and pass through the light-transmitting gap into the cavity formed by the groove, the light-shielding wall and the circuit board, and after being reflected by the outer wall of the light-shielding wall, the inner wall of the groove and the top wall in the cavity, it acts on the optical power detection component, which is used to realize real-time detection of the power of the light-emitting component.

[0039] By adopting the above technical solution, the optical power detection component obtains the intensity of light that is reflected by the light-transmitting gap and the outer wall of the light-shielding wall, the inner wall of the groove and the top wall and irradiates the detection area of ​​the optical power detection element. By continuously adjusting the actual light-emitting power of the light-emitting component and obtaining the corresponding detection power of the optical power detection element, the user can establish a corresponding relationship between the detection power and the actual power through tables or functions, which is convenient for judging the actual power by the detection power, performing real-time detection of the power of the light-emitting component, and improving the safety of the light source module.

[0040] Optionally, the sight mark film has a block extending outward in the circumferential direction, and the side wall of the sight mark groove has a notch matching the position of the block, which is configured to prevent the sight mark film from rotating on the lens holder and facilitate the installation and positioning of the sight mark film.

[0041] By adopting the above technical solution, the sight mark piece can be quickly installed on the lens base, and has the advantages of stable installation and avoidance of rotation relative to the lens base.

[0042] Optionally, the sight mark sheet is a transparent sheet with a pattern.

[0043] By adopting the above technical solution, a light spot with a pattern can be formed on the fundus of the user, that is, the user can see the light spot with a pattern. When the patterns are different, the functional diversity of the vision training mechanism can be improved.

[0050] By adopting the above technical solution, on the one hand, the sight tube is divided into a structure with two connected shells, which is used for rapid assembly of the light source module and the movable module, reducing the assembly difficulty. On the other hand, the cooperation between the limiting protrusion and the limiting groove prevents the light source module and the sight tube from rotating relative to each other. On the other hand, the limiting protrusions on both sides of the outer wall of the light source module and the limiting grooves on both sides of the interior of the sight tube can serve as guide structures, making the light source module run more smoothly inside the sight tube.

The patterns on the optometry film enable the user to more directly and clearly perceive the movement of the light source module as it moves back and forth during vision training. This allows the user's ciliary muscles to adjust the user's eyes on the basis of receiving light on the fundus, thereby improving the effect of vision training. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] The present application is further described in detail below with reference to the accompanying drawings.

[0071] The present application discloses a vision training mechanism based on sight marks, comprising:

[0072] The viewing tube A has a channel inside. The viewing tube A is a hollow tube, specifically a hollow circular tube, and is mainly used to create a closed training environment to prevent mutual influence between training lights (generally, there are two light source modules B corresponding to both eyes in one device).

[0073] In this example, the viewing tube A includes two shells 15 with a semicircular cross-section. The two shells 15 are connected by bolts. After the two shells 15 are assembled, concave limiting grooves 1501 are formed on both sides of the inner walls. The outer wall of the light source module B has a limiting protrusion 602 with a shape matching the limiting groove 1501. The limiting protrusion 602 is slidably connected in the limiting groove 1501.

[0074] The vision training mechanism further includes a light source module B configured to provide training light of a specified wavelength, power, size, and shape, which is disposed in the channel of the vision tube A and is movable along the length of the channel;

[0075] Specifically, the light source module B includes a circuit board; wherein the circuit board includes a first circuit board 1 and a second circuit board 2; the moving module C is located between the first circuit board 1 and the second circuit board 2;

[0076] An optical distance sensor 16 is mounted on the outer surface of the second circuit board 2. A reflector 14, compatible with the optical distance sensor 16, is located at one end of the interior of the viewing tube A and configured to detect the position of the light source module B within the viewing tube A. Specifically, the optical distance sensor 16 includes both emitting and receiving functions. Light emitted by the optical distance sensor 16 reaches the reflector 14 and is reflected to the light receiving area of ​​the optical distance sensor 16. Based on the emission time, light reception time, and light speed, the distance between the light source module B and the rear end of the viewing tube A can be calculated, thereby determining the position of the light source module B within the viewing tube A.

[0077] The light source module B further includes a light emitting element 3 , which is mounted on the surface of the circuit board and is used to emit initial light. Specifically, the light emitting element 3 is a semiconductor light emitting element, and specifically can be an LED generator.

[0078] The light source module B also includes a light source adjustment component, which is fixedly connected to the circuit board and is arranged in the illumination light path of the light emitting component 3. It is configured to partially block the initial light emitted by the light emitting component 3, and the remaining unblocked light passes through the light-transmitting hole at the end of the light source adjustment component.

[0079] Specifically, the light source adjustment member includes a first light source adjustment member 5 and a second light source adjustment member 6, wherein:

[0080] The first light source adjustment member 5 is a flange-shaped structure with an inwardly concave cylindrical groove 501 at the center of the bottom surface. The root of the groove 501 has a first light-transmitting hole 504 that passes through the first light source adjustment member 5.

[0081] The second light source adjustment member 6 is cylindrical in structure, one end of which is fixedly connected to the first light source adjustment member 5, and the other end of which has a second light transmission hole 601 which is connected to and coaxial with the first light transmission hole 504;

[0082] The light emitting element 3 is disposed in the cavity formed by the groove 501 and the circuit board. The light emitted by the light emitting element 3 passes through the first light-transmitting hole 504, enters the second light source adjustment member 6, and passes outward from the second light-transmitting hole 601 of the second light source adjustment member 6. After being converged and collimated into training light by the lens 7, the light is finally irradiated on the sight mark film 9.

[0083] The light source module B further includes:

[0084] The lens base 8 has a flange-like structure as a whole and is fixedly connected to the second light source adjustment member 6. A convex ring 801 is provided at the center of the lower surface thereof, extending into the second light-transmitting hole 601 of the second light source adjustment member 6, and the lens 7 is fixed in the convex ring 801. A sight mark groove 802 for mounting a sight mark film 9 is provided in the middle of the upper surface of the lens base 8. The center hole of the lens base 8 is coaxial with and connected to the inner hole of the convex ring 801, so that light can be irradiated on the sight mark film 9.

[0085] In this example, the light-emitting element 3 is an LED generator. Because LED light is scattered, with concentrated light in the center and sparser toward the periphery, the first light source adjustment member 5's groove 501, along its circumference and at its end near the first light-transmitting aperture 504, blocks the scattered light emitted from the LED generator. The denser LED light in the center region passes through the first light-transmitting aperture 504. In a specific embodiment, there is one light-transmitting aperture. When the light-emitting element 3 is an LED generator, the light-transmitting aperture filters the initial LED light into a first-stage LED light source. The first light-transmitting aperture 504 determines the intensity, spot size, and shape of this first-stage LED light source. After entering the second light source adjustment member 6, the light is reflected from within the second light source adjustment member 6 and blocked by the end wall near the second light-transmitting aperture 601. The larger the diameter of the second light source adjustment member 6, the better the internal blocking effect, allowing the light source to ultimately exit through the second light-transmitting aperture 601, achieving light adjustment.

[0086] The light source module B further includes:

[0087] An optical power detection element 4 is mounted on the surface of the circuit board and is located in the cavity formed by the groove 501 and the circuit board;

[0088] A light shielding wall 502 is located at the root of the groove 501 and extends outward. The light shielding wall 502 is arranged around the first light-transmitting hole 504. A light-transmitting notch 503 is opened in the circumferential direction of the light shielding wall 502. The light-transmitting notch 503 is located on the line connecting the optical power detection element 4 and the light-emitting element 3;

[0089] The light emitted by the light-emitting element 3 can be reflected by the inner wall of the light-shielding wall 502, pass through the light-transmitting notch 503, enter the cavity formed by the groove 501, the light-shielding wall 502, and the circuit board, and then act on the optical power detection element 4 after being reflected by the outer wall of the light-shielding wall 502, the inner wall of the groove 501, and the top wall in the cavity, thereby realizing real-time detection of the power of the light-emitting element 3. Some of the initial light emitted by the light-emitting element 3 that fails to pass through the first light-transmitting hole 504 will pass through the light-transmitting notch 503 and continuously reflect in the annular space outside the light-shielding wall 502. At this time, the optical power detection element can obtain the intensity of the light that is reflected and illuminates the detection area of ​​the optical power detection element. By continuously adjusting the actual light power of the light-emitting element 3 and obtaining the corresponding detection power of the optical power detection element, the user can establish a corresponding relationship between the detection power and the actual power through a table or function, so that the actual power can be determined by the detection power, thereby performing real-time detection of the power of the light-emitting element and improving the safety of the light source module B.

[0090] The second circuit board 2 of the light source module B is provided with a chip for controlling the operation of the drive motor 12 . The second circuit board 2 of the light source module B is also used to transmit signals to the first circuit board 1 to drive the operation of the light-emitting element.

[0091] The light source module B further includes a lens 7 fixed at the light-transmitting hole of the light source adjustment member, and configured to converge and collimate the light into training light.

[0092] The sight mark sheet 9 is detachably mounted on the optical path of the training light and is configured to allow the training light to pass through the sight mark sheet 9 and enter the user's fundus. The sight mark sheet 9 has an outwardly extending retaining block along its circumference, and the sidewalls of the sight mark slot 802 have notches that match the retaining block. This notch prevents the sight mark sheet 9 from rotating on the lens holder 8 and facilitates its installation and positioning.

[0093] Specifically, the sight mark sheet 9 is a transparent sheet with a pattern, which can be made of glass, resin, acrylic, or other transparent materials. After the training light passes through the sight mark sheet 9 and enters the user's fundus, it forms a patterned light spot on the user's fundus, which the user can see. More specifically, the pattern on the sight mark sheet 9 can be a cross mark or any other pattern that is clearly visible to the user, without limitation. The pattern on the sight mark sheet 9 allows the user to more directly and clearly perceive the movement of the light source module B during vision training. This allows the user's ciliary muscles to adjust the user's eyes in addition to the light received by the fundus, thereby improving the effectiveness of vision training.

[0094] The vision training mechanism further comprises a moving module C, which is mounted on the light source module B and is in transmission cooperation with the sight tube A, and is configured to drive the light source module B to move within the channel of the sight tube A.

[0095] Specifically, the mobile module C includes:

[0096] A driving motor 12, which is fixedly connected to the light source module B;

[0097] Gear 13, which is mounted on the shaft end of the drive motor 12;

[0098] The sight tube A has a rack 1502 inside, which is arranged on the inner wall of the sight tube A and has a length direction consistent with the length direction of the channel of the sight tube A. The rack 1502 can be integrally formed with the sight tube A or fixed to the inner wall of the sight tube A with bolts.

[0099] The gear 13 and the rack 1502 are meshed with each other. When the driving motor 12 is started, the gear 13 and the rack 1502 can drive the moving module C and the light source module B to move in the channel of the viewing tube A.

[0100] Specifically, the mobile module C also includes a motor bracket 11, which is fixedly connected to the light source module B. The driving motor 12 is connected to the motor bracket 11. The motor bracket 11 is located between the first circuit board 1 and the second circuit board 2. Two copper pillars 10 are installed inside the motor bracket 11. The upper end of the copper pillar 10 passes through the first circuit board 1 and is threadedly connected to the first light source adjustment member 5. There is a threaded hole in the center of the lower end. The bolt passes through the second circuit board 2 and is connected to the threaded hole at the lower end of the copper pillar 10. On the one hand, the purpose is to install and position the driving motor 12. On the other hand, the purpose is to set the second circuit board 2 at the outer end position for external installation of the optical distance sensor 16.

[0101] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
