Description

Technical Field

[0001] This utility model relates to the field of eye training device technology, and in particular to an eye movement training device. Background Technology

[0002] An eye training device is a device that helps improve vision or train eye muscles by simulating different visual environments. It typically uses adjustable lenses and a screen to help users train their vision by changing focal length, light intensity, and image presentation. These devices are commonly used for vision recovery, amblyopia correction, and relief of eye fatigue, and are particularly helpful for people who need to use their eyes for long periods, such as students and office workers.

[0003] The existing patent with publication number CN201920591545.2 discloses an eye movement training device, which includes a seat frame, a front end plate, and a shell forming a closed space. The shell has a base plate inside that is connected to the seat frame. The base plate has an interpupillary distance adjustment component, and its adjustment knob is located on the outside of the side of the shell. The interpupillary distance adjustment component has a pair of tunnel brackets for fixing the tunnel. The front end of the tunnel is connected to the eyepiece. The eyepiece passes through the front end plate as the user end. Multiple green light emission devices are provided in the tunnel and are electrically connected to the main board set on the base plate. The main board has a bio-inspired current emission module. The rear end of the shell also has an external interface that is electrically connected to the main board.

[0004] In the aforementioned technical solution, the interpupillary distance adjustment component uses two threaded sections with opposite directions on a screw to bring the two eyepieces closer together or further apart, thereby adjusting the interpupillary distance. However, since the two eyepieces can only move closer or further apart simultaneously, and the position of one eyepiece cannot be adjusted individually, this means the device is only suitable for users with symmetrical left and right eyes, while users with asymmetrical left and right eyes cannot use it, thus limiting its applicability. Furthermore, when the user rotates the screw, because the two eyepieces are located on opposite sides of the screw, the screw may experience slight twisting of the overall structure due to bidirectional force, especially when the screw is long (e.g., during large-pitch adjustment), potentially causing eyepiece wobbling and reducing the stability of the eyepiece movement. Utility Model Content

[0005] The main purpose of this invention is to provide an eye movement training device that expands its application range and improves the stability of the eyepiece during movement.

[0006] To achieve the above objectives, this utility model proposes an eye movement training device, including a base plate. The base plate is provided with a first eyepiece and a second eyepiece, and one side of both the first and second eyepieces extends to the outer side of the base plate. The first eyepiece is fixedly connected to the base plate. The base plate is provided with a movable groove on the side near the second eyepiece. The second eyepiece is slidably connected to the inner wall of the movable groove. An adjusting screw is rotatably connected to the side of the base plate near the second eyepiece. The second eyepiece is threadedly connected to the adjusting screw.

[0007] In one possible implementation, the base plate is connected to a first fixing plate and a second fixing plate on both sides near the bottom of the second eyepiece, and the first fixing plate and the second fixing plate are respectively disposed on both sides of the bottom of the second eyepiece. The adjusting screw is rotatably connected to the first fixing plate and the second fixing plate. A slider is fixedly connected to the bottom of the second eyepiece, and the slider is threadedly connected to the adjusting screw.

[0008] In one possible implementation, a guide rod is provided between the first fixed plate and the second fixed plate, and the two ends of the guide rod are fixedly connected to the first fixed plate and the second fixed plate respectively, and the slider is slidably connected to the guide rod.

[0009] In one possible implementation, a support block is fixedly connected to the side of the base plate away from the slider, the support block has an upper positioning groove, and a limiting block is fixedly connected to the bottom of the second eyepiece, the limiting block being slidably connected to the inner wall of the limiting groove.

[0010] In one possible implementation, the bottom of the slider is provided with countersunk holes at the four corners near the second eyepiece, and the bottom of the second eyepiece is provided with several threaded holes, with each threaded hole and each countersunk hole on the same axis.

[0011] In one possible implementation, the base plate has several fixing posts on the side near the first fixing plate and the second fixing plate, and the first fixing plate and the second fixing plate are fixedly connected to each fixing post by screws.

[0012] In one possible implementation, positioning posts are fixedly connected to the bottom of the base plate near the first fixing plate and the second fixing plate. Positioning holes are provided on the first fixing plate and the second fixing plate, and the positioning posts are slidably connected to the inner walls of the positioning holes.

[0013] In one possible implementation, the top of each of the positioning posts is an arc-shaped structure.

[0014] In one possible implementation, one side of the adjusting screw extends to the outside of the base plate and is fixedly connected to an adjusting block, the outer surface of which is provided with anti-slip texture.

[0015] The technical solution of this utility model fixes the first eyepiece, while the second eyepiece moves within a movable slot via an adjusting screw. This allows the user to adjust the position of the second eyepiece independently, using the first eyepiece as a reference, thereby meeting the special needs of asymmetrical interpupillary distances and expanding its applicability. Secondly, since the adjusting screw is only threadedly connected to the second eyepiece, it only bears unidirectional force during rotation, avoiding the problem of slight torsion of the overall structure caused by bidirectional force in traditional adjusting screws, thus improving the stability of the second eyepiece's movement. Simultaneously, unilateral adjustment reduces the length requirement of the adjusting screw (no need to span the entire base plate), lowering the risk of torsion caused by an excessively long screw and further improving the stability of the eyepiece's movement.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] refer to Figure 1-7 This embodiment proposes an eye movement training device, including a base plate 1. The base plate 1 is provided with a first eyepiece 101 and a second eyepiece 102, and one side of the first eyepiece 101 and the second eyepiece 102 extends to the outer side of the base plate 1. The first eyepiece 101 is fixedly connected to the base plate 1. The first eyepiece 101 can be fixedly connected to the base plate 1 by screws to facilitate installation or disassembly.

[0028] A movable groove 104 is provided on the side of the base plate 1 near the second eyepiece 102. The second eyepiece 102 is slidably connected to the inner wall of the movable groove 104. An adjusting screw 105 is rotatably connected inside the base plate 1 near the second eyepiece 102, and the second eyepiece 102 is threadedly connected to the adjusting screw 105. This design allows the first eyepiece 101 to be fixedly connected to the base plate 1 without being threadedly connected to the adjusting screw 105, greatly simplifying the structure of traditional interpupillary distance adjustment components and reducing the assembly difficulty between the first eyepiece 101 and the base plate 1.

[0029] Secondly, the technical solution of this embodiment fixes the first eyepiece 101 and moves the second eyepiece 102 in the movable groove 104 by adjusting the screw 105, so that the user can adjust the position of the second eyepiece 102 independently with the first eyepiece 101 as a reference, thereby meeting the special needs of asymmetrical interpupillary distance and expanding its applicable range.

[0030] Furthermore, a first fixing plate 106 and a second fixing plate 107 are respectively connected to the base plate 1 near the bottom of the second eyepiece 102. The first fixing plate 106 and the second fixing plate 107 are respectively located on both sides of the bottom of the second eyepiece 102. The adjusting screw 105 is rotatably connected to the first fixing plate 106 and the second fixing plate 107. A slider 108 is fixedly connected to the bottom of the second eyepiece 102. The slider 108 is threadedly connected to the adjusting screw 105.

[0031] Fixing the first fixing plate 106 and the second fixing plate 107 to the base plate 1 can provide support at both ends for the adjusting screw 105, reduce bending deformation when the screw rotates, especially when adjusting the large gap (the screw is long), and reduce the displacement deviation of the second eyepiece 102 caused by the shaking of the screw.

[0032] Meanwhile, this solution uses a slider 108 to connect with the adjusting screw 105 via a thread, instead of connecting the adjusting screw 105 to the second eyepiece 102 via a thread. This is intended to avoid the situation where, after prolonged use, wear occurs between the adjusting screw 105 and the slider 108, and the user only needs to replace the slider 108, rather than replacing the entire second eyepiece 102, thereby reducing maintenance costs.

[0033] Secondly, a guide rod 109 is provided between the first fixed plate 106 and the second fixed plate 107, and both ends of the guide rod 109 are fixedly connected to the first fixed plate 106 and the second fixed plate 107 respectively. The slider 108 is slidably connected to the guide rod 109. By providing the guide rod 109, the slider 108 is restricted to moving only along the axial direction of the guide rod 109, thereby preventing the second eyepiece 102 from shifting or misaligning during movement and improving the stability of the movement of the second eyepiece 102.

[0034] Furthermore, since the second eyepiece 102 is relatively long, it may tilt on the other side when one side is moved. To avoid this, a support block 2 is fixedly connected inside the base plate 1 on the side away from the slider 108. The support block 2 has an upper limit groove 201, and a limit block 202 is fixedly connected to the bottom of the second eyepiece 102. The limit block 202 is slidably connected to the inner wall of the limit groove 201.

[0035] By using the limiting block 202 and limiting groove 201, it can be ensured that the second eyepiece 102 remains perpendicular to the line of sight when moving horizontally (adjusting the interpupillary distance), avoiding optical axis deviation caused by tilting and improving the accuracy of training. At the same time, the limiting block 202 and limiting groove 201 can guide the eyepiece to move along a fixed trajectory, avoiding the "jamming" phenomenon caused by uneven force when the second eyepiece 102 moves.

[0036] In this embodiment, countersunk holes 1081 are provided at the four corners of the bottom of the slider 108 near the second eyepiece 102, and the bottom of the second eyepiece 102 is provided with a plurality of threaded holes 1021, and each threaded hole 1021 is on the same axis as each countersunk hole 1081.

[0037] The countersunk hole 1081 and threaded hole 1021 allow the slider 108 and the bottom of the second eyepiece 102 to be fixedly connected by screws. When the second eyepiece 102 or the slider 108 is damaged, it can be disassembled and replaced separately, reducing maintenance costs. At the same time, the countersunk hole 1081 can hide the screw head and avoid interference with the bottom of the base plate 1.

[0038] In this embodiment, several fixing posts 203 are provided inside the base plate 1 on the side near the first fixing plate 106 and the second fixing plate 107. The first fixing plate 106 and the second fixing plate 107 are fixedly connected to each fixing post 203 by screws. The screw connection method not only facilitates the replacement of damaged parts, but also facilitates assembly by assembly personnel.

[0039] Secondly, to facilitate the assembly of the first fixing plate 106, the second fixing plate 107 and the base plate 1, a positioning post 204 is fixedly connected to the bottom of the base plate 1 near the first fixing plate 106 and the second fixing plate 107. The first fixing plate 106 and the second fixing plate 107 are provided with positioning holes 205, and the positioning post 204 is slidably connected to the inner wall of the positioning hole 205.

[0040] During assembly, the positioning pins 204 and positioning holes 205 on the first fixing plate 106 and the second fixing plate 107 can be inserted into the positioning pins 204 to form a pre-positioning structure, which is then fixed with screws. The positioning pins 204 can guide the first fixing plate 106 and the second fixing plate 107 to quickly align, avoiding misalignment of the screw holes.

[0041] Meanwhile, the top of each positioning post 204 is designed with an arc-shaped structure. The arc-shaped end makes it easy for the positioning post 204 to be inserted into the positioning hole 205, reducing assembly resistance, and also avoids the right-angle edge from scratching the first fixing plate 106 or the second fixing plate 107.

[0042] During assembly, the assembler can first use screws to fix the second eyepiece 102 to the slider 108, then align the positioning holes 205 on the first fixing plate 106 and the second fixing plate 107 with the positioning posts 204 on the base plate 1, so that the positioning posts 204 are inserted into the positioning holes 205. Finally, the first fixing plate 106 and the second fixing plate 107 are connected to the fixing posts 203 using screws.

[0043] In this embodiment, one side of the adjusting screw 105 extends to the outside of the base plate 1 and is fixedly connected to an adjusting block 206. The outer surface of the adjusting block 206 is provided with anti-slip texture. The anti-slip texture can increase the friction, making it easier for the user to apply force when rotating the adjusting block 206 and preventing slippage.

[0044] Working principle:

[0045] To adjust the distance between the first eyepiece 101 and the second eyepiece 102, the user can align the line of sight of one eye with the first eyepiece 101, then rotate the adjusting block 206. The adjusting block 206 will rotate the adjusting screw 105, which in turn will move the slider 108 along the guide rod 109. At the same time, the second eyepiece 102 will move with the slider 108 within the movable slot 104 until it is aligned with the user's other eye, at which point the adjustment block 206 can be stopped.
