Description

Technical Field

[0001] This invention relates to a device essential for human life that uses dynamic changes in the depth of focus of eye imaging to stimulate and induce coordinated adjustment of the visual system, thereby improving eyesight. In particular, it is a turntable-type human visual system training device. Background Technology

[0002] Prolonged use of electronic devices (such as mobile phones and computers) or poor eye habits can lead to fatigue, tension, and spasms in the eye's accommodation system, resulting in various vision problems.

[0003] In existing technologies, the methods used to improve vision (or correct vision) are:

[0004] 1. Wearing glasses, while the main function of glasses is to correct vision and slow down the progression of myopia, does not relieve fatigue, tension or spasm of the eye's accommodation system, nor does it have the function of protecting eyesight. As the years of wearing glasses increase, the prescription also becomes higher and higher.

[0005] 2. Since poor eyesight is caused by unhealthy eye habits, the eye muscles' ability to adjust weakens, making it difficult to quickly adapt to changes in scenery. Existing technologies have developed numerous vision-improving assistive devices that use massage, heat therapy, and acupressure to relax the eye muscles and relieve eye fatigue.

[0006] In existing technologies, auxiliary devices can be used to relax eye muscles through massage, hot compresses, and stimulation to relieve eye fatigue, but the effect on improving vision is not ideal and cannot solve vision problems caused by the coordination and accommodation of the visual system. Utility Model Content

[0007] To address the issue of unsatisfactory vision improvement effects of existing assistive devices, this invention discloses a rotary human visual system training device. This device dynamically alters the depth of focus of the eye's image, stimulating and inducing the visual system to coordinate and adjust, thereby improving vision.

[0008] The technical solution adopted by this utility model to achieve the purpose of the invention is:

[0009] This invention is a rotary human visual system training device designed to improve eyesight by dynamically changing the depth of focus of eye imaging to achieve visual changes from blurry to clear or from clear to blurry, stimulating and inducing the visual system to coordinate and adjust.

[0010] The training device includes: a housing, a rotating disk, a baffle disk, and a rotating disk control mechanism.

[0011] The rotating disk and the baffle disk are coaxially mounted and fixedly supported on the housing. The baffle disk is inserted into the central conical hole of the rotating disk via a central conical shaft, and the baffle disk positioning pin on the baffle disk is inserted into the positioning hole on the rotating disk.

[0012] The shielding disc has a set of training holes of different radii evenly distributed on the same circumference or a set of training slits of different widths evenly distributed along the radial direction. The housing is provided with an observation hole. The set of training holes or training slits on the shielding disc is smaller than the observation hole on the housing. The observation hole on the housing is located at the same circumferential position as the training holes or training slits on the shielding disc.

[0013] Adhesive magnets are respectively provided on the contact end surfaces of the rotating disk and the baffle disk.

[0014] The rotating disk control mechanism is fixed on the housing, and the rotating disk control mechanism and the rotating disk form a transmission connection for rotating the rotating disk.

[0015] The beneficial effects of this invention are: simple structure, low cost, no side effects; by controlling the dynamic changes in the depth of focus, frequency, and combination of training holes or slits, it achieves multi-dimensional stimulation and induces the coordinated adjustment function of the visual system, thereby eliminating visual fatigue, tension, and spasms, and improving the coordinated adjustment ability of the visual system, ultimately improving eyesight. It is safe, convenient, has no side effects, and is easy to learn and operate.

[0016] The present invention will now be described in detail with reference to the accompanying drawings. Attached Figure Description

[0030] Referring to the attached diagram, a turntable-type human visual system training device.

[0031] The training device includes: a housing 1, a rotating disk 2, a baffle disk 4, and a rotating disk control mechanism.

[0032] The rotating disk 2 and the baffle disk 4 are coaxially mounted and fixedly supported on the housing 1. The baffle disk 4 is inserted into the central conical hole 2-2 of the rotating disk 2 via the central conical shaft 4-1. The baffle disk positioning pin 4-2 on the baffle disk 4 is inserted into the positioning hole 2-3 on the rotating disk 2.

[0033] The center positioning problem is solved by connecting the central conical shaft 4-1 to the central conical hole 2-2 of the rotating disk 2. The positioning pin 4-2 on the center plate 4 is connected to the positioning hole 2-3 on the rotating disk 2 to solve the problem of relative rotation between the center plate 4 and the rotating disk 2.

[0034] The shielding disc 4 has a set of training holes 4-3 of different radii evenly distributed on the same circumference or a set of training slits 4-4 of different widths evenly distributed radially. The housing 1 is provided with an observation hole 1-1. The set of training holes 4-3 or the set of training slits 4-4 on the shielding disc 4 are all smaller than the observation hole 1-1 on the housing 1. The observation hole 1-1 on the housing 1 is located at the same circumferential position as the training holes 4-3 or the training slits 4-4 on the shielding disc 4.

[0035] The observation hole 1-1 on the housing 1 and the training hole 4-3 or training slit 4-4 on the baffle plate 4 are positioned at the same circumference to ensure that after the baffle plate 4 is rotated, each training hole 4-3 or training slit 4-4 can be exposed through the observation hole 1-1 on the housing 1 to form a visual window with different depth of focus.

[0036] An adhesive magnet 8 is provided on the contact surface of the rotating disk 2 and the baffle disk 4. The adhesive magnet 8 ensures that the rotating disk 2 and the baffle disk 4 are tightly bonded and do not fall off.

[0037] The rotating disk control mechanism is fixed to the housing 1, and the rotating disk control mechanism and the rotating disk 2 form a transmission connection for the rotation of the rotating disk 2. This enables the rotating disk control mechanism to drive the rotating disk 2 to rotate.

[0038] In this embodiment of the automatic rotating disk control mechanism, the rotating disk control mechanism is a rotating disk motor 3, which is fixed on the housing 1. The output shaft of the rotating disk motor 3 is connected to the center hole 2-1 of the rotating disk 2. By controlling the rotation angle of the rotating disk motor 3, each training hole 4-3 or training slit 4-4 can be exposed through the observation hole 1-1 on the housing 1 to form a visual window with different depths of focus.

[0039] In this embodiment of the manual rotary disc control mechanism, the rotary disc 2 is provided with ratchet teeth 2-4.

[0040] The rotating disk control mechanism includes: a limiting pawl 5, an active pawl 6, and a pawl control lever 7.

[0041] The limiting pawl 5 is rotatably mounted on the housing 1 via a torsion spring, and the limiting pawl 5 engages with the ratchet teeth 2-4 on the rotating disk 2.

[0042] The active pawl 7 is mounted on one end of the pawl control rod 7 via the pawl control spring 6-1, and the pawl control rod 7 is mounted on the housing 1 via the control rod spring 7-1.

[0043] Press the pawl control lever 7, and the active pawl 6 will push the rotating disk 2 to rotate via the ratchet 2-4 on the rotating disk 2. Each training hole 4-3 or training slit 4-4 can be exposed through the observation hole 1-1 on the housing 1 to form a visual window with different depth of focus.

[0044] Release the pawl control lever 7, limit the pawl 5 to restrict the rotation of the rotating disk 2, and the active pawl 6 compresses the pawl control spring 6-1 under the action of the ratchet 2-4 to retract. The pawl control lever 7 is reset under the action of the control lever spring 7-1, completing one rotation of the manual rotating disk 2.

[0045] In another embodiment of the manual rotary disc control mechanism of this utility model, the rotary disc 2 is provided with ratchet teeth 2-4.

[0046] The rotating disk control mechanism includes: a limiting pawl 5, an active pawl 6, and a pawl control lever 7;

[0047] The limiting pawl 5 is rotatably mounted on the housing 1 via a torsion spring, and the limiting pawl 5 engages with the ratchet teeth 2-4 on the rotating disk 2.

[0048] One end of the pawl control lever 7 is rotatably mounted on the central shaft of the rotating disk 2, and the active pawl 6 is rotatably mounted on the pawl control lever 7.

[0049] The housing 1 is provided with an arc-shaped pawl limiting groove 1-2, and the rotating shaft of the active pawl 6 is set in the pawl limiting groove 1-2. By moving the pawl control rod 7 to rotate around the central axis of the rotating disk 2, the active pawl 6 drives the rotating disk 2 to rotate.

[0050] In this embodiment of the utility model, in order to accurately control the rotation angle of the rotating disk motor 3, a rotation angle sensor 9 is provided between the rotating disk 2 and the rotating disk motor 3.

[0051] In this embodiment of the invention, the housing 1 is further provided with a foldable eye shield 10.

[0052] When this invention is used to train only one eye, the eye shading baffle 10 blocks light from the other eye. The shading baffle 10 can also be used to block light from the training eye.

[0053] In this embodiment of the utility model, the configuration can be symmetrically arranged as shown in the attached figure. Figure 6 The illustrated embodiment is a binocular wearing type. This binocular wearing embodiment requires an external adjustment joint for easy nose bridge adjustment. Alternatively, it can be used alone as shown in the attached figure.
