Description

Technical Field

[0001] This invention relates to the field of vision training equipment technology, specifically a comprehensive vision training device. Background Technology

[0002] With the development of technology and the widespread use of electronic devices, people spend significantly more time using them. Coupled with close-range eye use during study and work, the incidence of myopia is showing a rapid upward trend and is affecting younger people. Currently, there are many solutions for vision problems on the market, but they all have significant limitations. Glasses, as the most common vision correction tool, are only optical compensations and cannot fundamentally improve vision or prevent the further development of myopia. Therefore, there is a particular need for intelligent vision training devices.

[0003] Traditional vision training devices (such as amblyopia treatment devices and vision training frames) are mostly fixed structures that occupy the entire desktop or wall when unfolded. They cannot be folded, resulting in high storage and transportation costs. Furthermore, the training methods rely on static eye charts, single red light flashing, or simple manual tracking (such as pen tip movement). The stimulation patterns are fixed, making it difficult to scientifically train eye movements. Vision testing (such as eye charts) and training (such as reverse test and bead stringing) usually need to be operated separately. Switching between devices is time-consuming and relies on manual adjustments by medical staff (such as changing eye chart cards and adjusting the position of the light source), making the operation cumbersome and prone to errors. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Attached Figure 3 This invention provides a comprehensive vision training device, comprising: a base frame 1 for fixing the structure of the comprehensive vision training device; a top frame 2 located on the base frame 1 for opening, closing, and rotating the base frame 1; a traction rod 1 3, a central support rod 4, and a traction rod 2 5 located on the base frame 1 for supporting and traction of the base frame 1 and the top frame 2 for folding and closing; the top frame 2 is rotatably mounted on the base frame 1; an unfolding output mechanism 6 is located between the top frame 2 and the base frame 1; a training bearing mechanism 7 is located between the unfolding output mechanism 6 and the top frame 2; a vision testing mechanism 8 is located on the unfolding output mechanism 6; a real-time pressing mechanism 9 is located on the vision testing mechanism 8; and a vision training mechanism 10 is located on the unfolding output mechanism 6. This device is mainly used for vision training. Medical personnel open the top frame 2 by rotating it, causing the top frame 2 to rotate and open along the base frame 1, thus opening the top frame 2. The traction rod 1 3 installed inside the top frame 2 moves along with the traction rod 5 installed on the base frame 1. The top frame 2 unfolds by rotating the second rod 5. Medical staff can also manually push the central support rod 4 to rotate it, so that the top frame 2 begins to rotate and close along the bottom frame 1. At the same time as the top frame 2 closes, the first unfolding platform 61 and the second unfolding platform 62 also fold into the bottom frame 1 along the stepped shape. While the first unfolding platform 61 rotates, the training inclined frame 71 also rotates and folds into the first unfolding platform 61 along the first traction rod 72 and the second traction rod 73. While the training inclined frame 71 rotates and descends, the traction damping rod 88 will also push the linkage frame 82 to descend, so that the linkage frame 82 is re-embedded into the installation cavity 63. The tail pulley 83 will be reset to the end of the horizontal frame 81 along with the snap ring structure, so that the vision testing mechanism 8 is folded into the installation cavity 63. At the same time as the top frame 2 is completely covered on the bottom frame 1, the unfolding output mechanism 6, the training bearing mechanism 7 and the vision testing mechanism 8 are also folded, and the displacement folding mechanism 13 is folded back to the original folding state.

[0023] Please see the appendix Figure 1 -Attached Figure 7The unfolding output mechanism 6 is located on the base frame 1 and is used to unfold inside the base frame 1 to form a training work area. The unfolding output mechanism 6 includes an unfolding platform 1 61, an unfolding platform 2 62, and a support short rod 2 66. The unfolding platform 1 61 is located above the unfolding platform 2 62, and the mounting cavity 63 is located inside the unfolding platform 1 61. The support short rod 2 66 rotates around the middle of both sides of the unfolding platform 1 61. The end of the support short rod 2 66 away from the unfolding platform 1 61 rotates around the side wall of the unfolding platform 2 62. The end of the support short rod 2 66 away from the unfolding platform 1 61 is rotatably connected to a contact rod 67. The other end of the contact rod 67 rotates around the inside of the top frame 2. The end of the central support rod 4 away from the traction single rod 2 5 rotates around the support short rod 2 66. The built-in groove of the mounting cavity 63 is located on the inner wall of the mounting cavity 63. The two sides of the head of the unfolding platform 2 62 are rotatably connected to the support short rod 1 64. The support short rod 1 64 is located away from the unfolding platform 2 62. One end of 62 rotates inside the base frame 1. The head of the first unfolding platform 61 is rotatably connected to the two sides of the support rod 65. The middle of the support rod 65 rotates to the middle of the two sides of the second unfolding platform 62. First, the unfolding output mechanism 6 also unfolds. The contact rod 67, which is rotatably installed on the side wall of the first unfolding platform 61 included in the unfolding output mechanism 6, is pulled and dragged to rotate and unfold the first unfolding platform 61 as the top frame 2 opens. The first unfolding platform 61 also drives the support rod 65 and the support rod 64 to rotate at the same time, so that the first unfolding platform 61 and the second unfolding platform 62, the first unfolding platform 61 and the second unfolding platform 62 included in the unfolding output mechanism 6 unfold in a stepped manner. The central support rod 4, which is installed at the end of the support rod 66, also rotates and unfolds with the central support rod 4 and supports the end connected to the traction rod 3 and the traction rod 5. At the same time, it supports the opening of the entire top frame 2, and the entire training equipment opens accordingly.

[0024] Please see the appendix Figure 1 -Attached Figure 6The training support mechanism 7 is located on the unfolding output mechanism 6 and works with the unfolding platform 61 to form an inclined display. The training support mechanism 7 includes a training inclined frame 71, with limit grooves on both sides of the training inclined frame 71. A traction rod 72 is slidably connected inside the limit grooves of the training inclined frame 71. The end of the traction rod 72 away from the training inclined frame 71 rotates inside the top frame 2. A traction rod 73 is rotatably connected to the side wall of the training inclined frame 71 away from the limit grooves. The end of the traction rod 73 away from the training inclined frame 71 rotates inside the unfolding platform 61. When the unfolding platform 61 unfolds, the training support mechanism 7... The included traction rod 2 73 is also supported by the unfolding platform 1 61. The rotation of the top frame 2 also pulls the traction rod 1 72 and the training inclined frame 71 attached to the end of the traction rod 1 72 to rotate and unfold. The end of the traction rod 1 72 connected to the training inclined frame 71 slides along the limiting groove and rotates to support the training inclined frame 71. The training inclined frame 71 is also supported as the traction rod 2 73 unfolds, so that the training inclined frame 71 is fixed in an inclined posture and forms an inclined display area through its own inclined platform. The vision training mechanism 10, which is mainly used for vision training, is fixed on the training inclined frame 71.

[0025] Please see the appendix Figure 1 -Attached Figure 8The vision testing mechanism 8 is located on the unfolding output mechanism 6. It works in conjunction with the built-in groove structure of the mounting cavity 63 and the training inclined frame 71 to display a freely adjustable vision chart. The vision testing mechanism 8 includes a horizontal frame 81, a linkage frame 82, a positioning slide 87, and a tension damping rod 88. The horizontal frame 81 is fixed inside the mounting cavity 63 near the top frame 2. A sliding groove is provided on the inner side of the horizontal frame 81, and a tail pulley 83 is slidably connected through the groove. Both ends of the tail pulley 83 slide within the built-in groove of the mounting cavity 63, and a retaining spring structure is embedded between the tail pulley 83 and the inner wall of the built-in groove. A steering pulley 84 is rotatably connected to the middle of the inner side of the horizontal frame 81. The positioning slide 87 is fixed inside the mounting cavity 63. Near the linkage frame 82, the linkage frame 82 is slidably embedded in the positioning slide 87 via pulley structures on both sides. A traction pulley 85 is rotatably connected to the inner side of the linkage frame 82, and a head pulley 86 is rotatably connected to the inner side of the linkage frame 82 away from the traction pulley 85. The head pulley 86, traction pulley 85, steering pulley 84, and tail pulley 83 are connected by a belt. One end of the traction damping rod 88 rotates on the outer end of the traction pulley 85, and the other end rotates on the bottom wall of the training inclined frame 71. The development platform 61 itself has a vision testing mechanism 8 installed in the mounting cavity 63. The vision testing mechanism 8 includes a horizontal frame 81 installed in the mounting cavity 63. Inside the 3rd section, the included linkage frame 82 also slides along the straight line inside the mounting cavity 63 via positioning slides 87 mounted on both sides. The transverse frame 81 itself has a tail pulley 83 and a steering pulley 84 arranged side-by-side. The steering pulley 84 is rotatably mounted inside the transverse frame 81, while the tail pulley 83 is slidably mounted on the inner wall of the transverse frame 81. Both ends of the tail pulley 83 extend into the built-in groove inside the mounting cavity 63, and a retaining spring structure is added inside the built-in groove. As the tail pulley 83 slides along the transverse frame 81 and the built-in groove, it compresses the retaining spring. The tail pulley 83, steering pulley 84, pulley 85, and head pulley... The outer surface of the 86 is simultaneously traction belt, on which visual acuity charts of different observation levels are engraved. When the training inclined frame 71 is unfolded, it pulls the traction damping rod 88, and through the traction damping rod 88, it pulls the linkage frame 82 to rise along the positioning slide 87. This drives the linkage frame 82, equipped with the first pulley 86 and the traction pulley 85, to rise the belt area it is connected to, forming an independent display area. The trainee can adjust the operation of the belt through the tail pulley 83, the steering pulley 84, the traction pulley 85, and the first pulley 86, so that visual acuity charts of different levels can be moved to the independent display area formed by the first pulley 86 and the traction pulley 85 for the trainee to observe their vision.

[0026] Please see the appendix Figure 1 -Attached Figure 9The real-time clamping mechanism 9 is located on the vision testing mechanism 8 and works with the linkage frame 82 to lock and adjust the vision chart in real time. The real-time clamping mechanism 9 includes a suspension 91 and a crankshaft 93. The suspension 91 is fixed to the top of the linkage frame 82. A central rotating rod 92 is rotatably connected inside the suspension 91. The central rotating rod 92 is fixed to the middle of the crankshaft 93. A pressing block 94 is fixedly connected to one end of the crankshaft 93. A rubber block 95 is fixedly connected to the bottom wall inside the suspension 91. The rubber block 95 is inclined to face the crankshaft 93. In the crank section, the trainee can also manually push up the crankshaft 93 included in the real-time pressing mechanism 9, so that the crankshaft 93 rotates along the rubber block 95 on the suspension 91, pressing the pressing block 94 fixed at the other end of the crankshaft 93 against the belt end of the pulley 85, so that the belt end can be locked in real time. The crankshaft 93 also presses against the rubber block 95 fixed on the suspension 91. When it is released, the rubber block 95 will push the crankshaft 93 back to its original position so that the belt end can be adjusted to display different levels of visual acuity chart.

[0027] Please see the appendix Figure 1 -Attached Figure 11 The vision training mechanism 10 is located on the training support mechanism 7 and, together with the training inclined frame 71, forms the main structure of the vision training system. The vision training mechanism 10 includes a polygonal outer frame 101, which is fixed to the training inclined frame 71. Halogen lamp light sources 102 are arranged in two rows and circumferentially on the surface of the polygonal outer frame 101. Red light sources 103 are arranged in a single row and circumferentially on the surface of the polygonal outer frame 101. An LED display screen 104 is located at the center of the surface of the polygonal outer frame 101. Circuit boards 105 corresponding to the halogen lamp light sources 102 and the red light sources 103 are located inside the polygonal outer frame 101. A switching power supply 106 is also located inside the polygonal outer frame 101. The polygonal outer frame 101 itself is a regular octagonal metal sheet structure. The white paint and matte finish reduce eye strain from prolonged staring. Each corner of the display surface is equipped with a stable light source similar to a halogen lamp. The display surface is equipped with two rows of halogen lamps 102 arranged in a circle around the polygonal frame 101, and a single row of red lamps 103 also arranged in a circle around the polygonal frame 101. Together with the LED display screen 104 at the center of the polygonal frame 101, the system forms the eye training display trajectory light source. The system sends control commands to the remote control or the touch function of the LED display screen 104, which then drives the halogen lamps 102, the red lamps 103, and the LED display screen 104 to light up. By adjusting the display trajectory, direction, and cycle of the LEDs, the system can induce regular and rhythmic eye movements and relaxation, thereby improving various types of weak and near vision.

[0028] Working Principle: This device is mainly used for vision training. Medical staff open the top frame 2 by rotating it, causing the top frame 2 to rotate and open along the bottom frame 1. As the top frame 2 opens, the traction rod 3 installed inside it unfolds along with the traction rod 5 installed on the bottom frame 1. Simultaneously, the unfolding output mechanism 6 also unfolds. The contact rod 67, which is rotatably installed on the side wall of the unfolding platform 61 included in the unfolding output mechanism 6, is pulled and dragged by the unfolding platform 61 as the top frame 2 opens, causing the unfolding platform 61 to rotate and unfold. The unfolding platform 61 also simultaneously drives the long support rod 65 and the short support rod 64 to rotate, causing the unfolding platform 61 and the unfolding platform 62, as well as the unfolding platform 61 and the unfolding platform 62 included in the unfolding output mechanism 6, to move in a stepped manner. As the platform unfolds, the central support rod 4, attached to the end of the second support rod 66, also rotates and unfolds, supporting the end connecting the first traction rod 3 and the second traction rod 5. Simultaneously, it supports the opening of the entire top frame 2, and the entire training equipment opens accordingly. As the unfolding platform 61 unfolds, the second traction rod 73, included in the training support mechanism 7, is also supported by the unfolding platform 61. The rotation of the top frame 2 pulls the first traction rod 72 and the training inclined frame 71 attached to the end of the first traction rod 72 to rotate and unfold. The top frame 2 rotates and unfolds, and the end of the first traction rod 72 connected to the training inclined frame 71 slides along the limiting groove while simultaneously rotating to support the training inclined frame 71. The training inclined frame 71 also unfolds and is supported along with the second traction rod 73, thus supporting the training inclined frame. The frame 71 is fixed in an inclined position, forming an inclined display area through its own inclined platform. The vision training mechanism 10, which is mainly used for vision training, is fixed on the inclined training frame 71. The vision training mechanism 10 includes a polygonal outer frame 101, which is a regular octagonal sheet metal structure, painted with medical white paint, and has a matte finish to reduce eye strain from prolonged staring. Each corner of the display surface is equipped with a stable light source similar to a halogen lamp. The halogen lamp light sources 102 arranged in two rows and circumferentially on the display surface of the polygonal outer frame 101, and the red light source 103 arranged in a single row and circumferentially on the display surface of the polygonal outer frame 101, together with the LED display screen 104 in the center of the display surface of the polygonal outer frame 101, form the display trajectory light source for eye training. It can be controlled by a remote control. Alternatively, the LED display screen 104 can send system control commands via its touch function, thereby driving the halogen lamp light source 102, the red light source 103, and the LED display screen 104 to light up. The system adjusts the display trajectory, display direction, and display cycle of the LEDs to cause the human eyeballs to rotate rhythmically and relax, thereby improving various types of weak and near vision. The display stand 61 itself has a vision testing mechanism 8 installed in the mounting cavity 63. The vision testing mechanism 8 includes a horizontal frame 81 installed inside the mounting cavity 63, and the included linkage frame 82 also slides inside the mounting cavity 63 along a straight line installed on the inner side of the mounting cavity 63 via positioning slides 87 added on both sides. The horizontal frame 81 itself has a tail pulley 83 and a steering pulley 84 arranged side by side.The steering pulley 84 is rotatably mounted inside the transverse frame 81, while the tail pulley 83 is slidably mounted on the inner wall of the transverse frame 81. Both ends of the tail pulley 83 extend into the built-in grooves inside the mounting cavity 63, and a retaining spring structure is added inside the grooves. As the tail pulley 83 slides along the transverse frame 81 and the built-in grooves, it compresses the retaining springs. The outer surfaces of the tail pulley 83, steering pulley 84, traction pulley 85, and head pulley 86 simultaneously pull the belt, which is correspondingly engraved with visual acuity charts for different observation levels. When the training inclined frame 71 is unfolded, it pulls the traction damping rod 88, and through the traction damping rod 88… The traction linkage frame 82 rises along the positioning slide 87, driving the first pulley 86 and the pulley 85 attached to the linkage frame 82 to rise the belt area it is connected to, forming an independent display area. The trainee can adjust the operation of the belt through the tail pulley 83, the steering pulley 84, the pulley 85, and the first pulley 86, so that different levels of vision charts can be moved to the independent display area formed by the first pulley 86 and the pulley 85 for the trainee to observe their vision. The trainee can also manually push up the crankshaft 93 included in the real-time clamping mechanism 9, so that the crankshaft 93 rotates along the rubber block 95 on the suspension 91. The pressing block 94, fixed to the other end of the crankshaft 93, presses against the belt end of the pulley 85, allowing the belt end to be locked in real time. Simultaneously, the crankshaft 93 presses against the rubber block 95 fixed to the suspension 91. When released, the rubber block 95 pushes the crankshaft 93 back to its original position, allowing for continued adjustment of the belt end to display different levels of visual acuity. Medical personnel can also manually push the central support rod 4 to rotate it, causing the top frame 2 to begin rotating and closing along the bottom frame 1. Simultaneously, as the top frame 2 closes, the first unfolding platform 61 and the second unfolding platform 62 fold into the bottom frame 1 in a stepped configuration. While the first unfolding platform 61 rotates... The training inclined frame 71 also rotates and folds into the interior of the unfolding platform 61 along the first traction rod 72 and the second traction rod 73. As the training inclined frame 71 rotates and descends, the traction damping rod 88 pushes the linkage frame 82 to descend, causing the linkage frame 82 to re-embed into the mounting cavity 63. The tail pulley 83 returns to the end of the horizontal frame 81 along with the snap ring structure, causing the vision testing mechanism 8 to fold entirely into the mounting cavity 63. As the top frame 2 completely covers the bottom frame 1, the unfolding output mechanism 6, the training bearing mechanism 7, and the vision testing mechanism 8 also fold, simultaneously causing the displacement folding mechanism 13 to fold back to its original folded state.
