Description

Technical Field

[0001] This utility model relates to the field of virtual reality glasses technology, and in particular to anti-fatigue electronic glasses for learning. Background Technology

[0002] Currently, the human eye sees objects by forming an inverted image on the retina through the lens, which is the same as the imaging principle of a convex lens. Therefore, the object must be beyond the focal length of the human eye to be seen clearly. So when the object is close to the human eye, the human eye needs to compress the lens to make the focal length closer. Over time, this can easily lead to myopia.

[0003] Students, in particular, often need to look at objects at close range for extended periods of time while doing their homework.

[0004] Currently, there are many ways to address and prevent myopia, mainly relying on equipment for repair or protection, as well as personal habits for prevention. However, when studying, the distance between the object and the eyeball needs to be within a reasonable range. When the distance between the eye and the object is too small, the lens needs to be compressed in order to see the object clearly. Being in this state for a long time will lead to myopia. To prevent this, people will release the lens by looking into the distance or closing their eyes and massaging it.

[0005] However, in the existing technology, it is not convenient for people to control the timing and method of looking into the distance and massaging with their eyes closed during the release process of the human eye lens. The actual operation is quite limited, and the actual effect on reducing the focusing pressure of the eyeball and relieving the compression of the lens to prevent myopia is relatively limited. In view of this, we propose anti-fatigue electronic glasses for learning. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide anti-fatigue electronic glasses for learning. This invention addresses the current technical problem that, during the release process of the human eye's lens, it is inconvenient for people to grasp the timing and method of looking into the distance and massaging with their eyes closed, resulting in high limitations in actual operation. As a result, the actual effect of these glasses on reducing eyeball focusing pressure and alleviating lens compression to prevent myopia is relatively limited.

[0007] To achieve the objectives of this utility model, the technical solution adopted by this utility model is as follows:

[0008] Users wear glasses-like displays while doing their homework and adjust the camera module to a suitable position. The camera module captures real-time images of the actual homework scene, including the table, textbook, pen, and hand. The glasses-like displays use a display module that includes a high-magnification optical module and a high-definition micro-display screen. The glasses-like displays are used to magnify and display the real-world homework scene captured by the camera module. The glasses-like displays also provide a high-definition, real-time immersive display of the real-world homework scene from a distance, specifically including the table, textbook, pen, and hand.

[0009] By placing the high-definition microdisplay at the center between the front focal point and the convex lens, the light emitted by the pixels on the high-definition microdisplay is refracted after passing through the convex lens.

[0010] Furthermore, according to the principle of virtual image formation by a convex lens, light rays passing through the center of the lens do not refract, while light rays parallel to the principal axis of the lens will converge at the rear focal point.

[0011] Taking a pixel as an example, the light rays emitted by a pixel that are parallel to the principal optical axis and pass through the center of the lens are shown in the figure. At this time, the light rays perceived by the human eye are as if they are emitted from a virtual pixel.

[0012] Therefore, each pixel on a high-definition micro display screen has a corresponding virtual image, and these pixels together form the virtual display screen.

[0013] The human eye sees objects by forming an inverted image on the retina through the lens, which is the same as the imaging principle of a convex lens. Therefore, the object must be more than twice the focal length of the human eye to be seen clearly. So when the object is close to the human eye, the human eye needs to compress the lens to make the focal length closer. Over time, this can easily lead to myopia.

[0014] Since the scene of doing homework is emitted through a high-definition miniature display screen, the light perceived by the human eye is as if it is emitted from a virtual display screen. Since the virtual display screen is farther away, the human eye does not need to adjust the focal length of the eye to be particularly close, and therefore does not compress the lens. This avoids long-term compression of the lens, which can lead to ciliary fatigue and thus prevent myopia.

[0015] In addition to using the aforementioned optical technologies to relax the ciliary body of the eye, virtual reality technology can also magnify the font in the exercise book displayed in the scene, making it easier for people to see clearly and also relaxing the eyes.

[0016] Furthermore, by monitoring the duration of device usage, it can automatically display relaxing scenes on an electronic screen to relieve eye fatigue and provide optical massage to relax the eyes.

[0017] Since the homework assignment is displayed on the glasses monitor, users do not need to look down or up excessively, ensuring a comfortable writing position to avoid discomfort in the cervical and spinal spine.

[0018] Anti-fatigue electronic glasses for learning also include a glasses display and a detachable strap assembly connected to the glasses display for wearing;

[0019] When a user is doing homework, they first wear the glasses display via a strap component. The camera component is used to capture the real homework scene in real time, specifically the image of the table, textbook, pen, and hand. The glasses display is used to project the real homework scene, specifically the image of the table, textbook, pen, and hand.

[0020] To effectively address the problem of lens compression caused by excessively small focal length, thereby reducing eye focusing pressure and lens compression, the glasses display includes a housing and an inner housing installed within the housing. A shooting component is detachably mounted on one end of the housing. A high-definition miniature display screen is fixedly installed on one side of the inner housing, and a support plate is installed on the side of the inner housing away from the high-definition miniature display screen. Two circular grooves are symmetrically formed on one side of the support plate, and convex lenses are fixedly installed in both of the circular grooves.

[0021] The video images played on the high-definition miniature display screen are affected by the convex lens to generate virtual distant scene imaging. The external environment is captured by the shooting component and played on the high-definition miniature display screen, which can effectively solve the problem of lens compression caused by excessively small focal length. It can effectively reduce the focusing pressure of the eyeball and the compression of the lens, and can effectively avoid ciliary body fatigue caused by long-term compression of the lens, thereby avoiding myopia.

[0022] In addition to using the aforementioned optical technologies to relax the ciliary body of the eye, virtual reality technology can also magnify the font in the exercise book displayed in the scene, making it easier for people to see clearly and also relaxing the eyes.

[0023] Furthermore, by monitoring the duration of device usage, it can automatically display relaxing scenes on an electronic screen to relieve eye fatigue and provide optical massage to relax the eyes.

[0024] Furthermore, to facilitate adjustment of the shooting angle, the shooting component includes a front cover. Two cameras are symmetrically mounted on the side of the front cover away from the outer shell, and two extension ears are symmetrically mounted on the side of the front cover facing the outer shell. A groove is centrally located at one end of each side of the outer shell, and a fastening bolt is threaded into each of the two grooves. A through slot is centrally located on one side of each extension ear for the fastening bolt to pass through. The shooting component captures images of the external environment, which are then played back on a high-definition miniature display screen. During shooting, the two fastening bolts can be loosened to rotate the front cover with the two extension ears, thereby adjusting the orientation of the cameras. After adjustment, the two fastening bolts are tightened again to secure the front cover, thus adjusting the shooting component to a suitable position. It is convenient to use and easy to operate.

[0025] Because the scene of doing homework is captured by a downward-flipping camera and played on the glasses' display, users must keep their backs straight to see the homework, thus solving the problem of students hunching over while doing homework for long periods of time, which affects their posture.

[0026] Furthermore, to improve wearing comfort, extension rods are centrally located on both sides of the inner shell, and a fixing sleeve is constructed at one end of the extension rod extending out of the outer shell. The strap assembly includes a restraint strap, with both ends of the restraint strap respectively installed in the two fixing sleeves. A top strap is centrally fixed between the top of the restraint strap and the top of the inner shell. Both sides of the restraint strap are fixedly installed to the support arm, and an earphone is fixedly installed at one end of the support arm. A face frame is detachably installed at one end of the inner shell, and a support pad is adhesively fixed to one side of the face frame. The glasses display can be fixed to the user's head and positioned to the side of the user's eyes by the restraint strap and the top strap. After fixing, the position of the two earphones can be adjusted to move them to the ears to play music. After wearing, the support pad on the face frame will relieve the pressure of the inner shell on the face, resulting in a high level of wearing comfort.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This invention uses two convex lenses to refract the video image played on the display screen, thereby generating a virtual display screen image at a distance. This allows the image to converge at the focal point on the eyeball, thus forming an image on the retina. This avoids the problem of excessive compression of the lens. By capturing images of the external environment through the imaging component and playing them on the display screen, it effectively solves the problem of lens compression caused by excessively short focal length. It effectively reduces the focusing pressure on the eyeball and the compression of the lens, which can effectively prevent myopia. It is also quite convenient to operate in practice.

[0029] 2. Virtual reality technology can also magnify the font in the exercise book in the display scene, making it easier for people to see and relax their eyes. At the same time, by monitoring the duration of device use, it can automatically play some relaxing scenes on the electronic screen to relieve fatigue, provide optical massage to relax the eyes, and prevent myopia.

[0030] 3. The homework scenario is displayed on the glasses monitor, so users do not need to look down or up excessively, ensuring a comfortable writing position to avoid discomfort in the cervical and spinal spine.

[0031] 4. It solves the problem of students hunching over or looking down while doing homework for extended periods, which affects their posture. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0041] Example 1: As Figure 1 As shown, in this embodiment, the shooting component 6 and the glasses display 1 are separate designs. The shooting component 6 can be fixed on a table or a stand. When the user is doing homework, they wear the glasses display 1 and adjust the shooting component 6 to a suitable position. The shooting component 6 is used to capture the scene of the real homework in real time, specifically including the image of the table, textbook, pen, and hand. The display module of the glasses display 1 includes an optical high-magnification module and a high-definition micro display screen 10. The glasses display 1 is used to display the real homework scene captured by the shooting component 6 in high magnification. The glasses display 1 is used to display the scene of the real homework in real time in high-definition magnification from a distance from the human eye's perspective, specifically including the image of the table, textbook, pen, and hand.

[0042] like Figure 2 As shown, a common convex lens 7 is selected as the optical high-magnification module. By placing the high-definition micro display screen 10 in the middle of the front focal point 71 and the convex lens 7, the light emitted by the pixels on the high-definition micro display screen 10 is refracted after passing through the convex lens 7.

[0043] Furthermore, according to the principle of virtual image formation by a convex lens, light rays passing through the center of the lens do not refract, while light rays parallel to the principal optical axis of the lens will converge at the rear focal point 72.

[0044] Taking pixel 9 as an example, the light emitted by pixel 9 is parallel to the principal optical axis and passes through the center of the lens, as shown in the figure. At this time, the light perceived by the human eye is as if it is emitted from virtual pixel 91.

[0045] Therefore, each pixel on the high-definition miniature display screen 10 has a corresponding virtual image, and these pixels together form the virtual display screen 100.

[0046] The human eye sees objects by forming an inverted image on the retina through the lens, which is the same as the imaging principle of a convex lens. Therefore, the object must be more than twice the focal length of the human eye to be seen clearly. So when the object is close to the human eye, the human eye needs to compress the lens to make the focal length closer. Over time, this can easily lead to myopia.

[0047] Since the scene of doing homework is emitted through the high-definition miniature display screen 10, the light perceived by the human eye 8 is as if it is emitted from the virtual display screen 100. Since the virtual display screen 100 is farther away, the human eye 8 does not need to adjust the focal length of the eye to be too close, and therefore will not compress the lens, thus avoiding long-term compression of the lens and ciliary fatigue, thereby avoiding myopia.

[0048] In addition to using the aforementioned optical technologies to relax the ciliary body of the eye, virtual reality technology can also magnify the font in the exercise book displayed in the scene, making it easier for people to see clearly and also relaxing the eyes.

[0049] Furthermore, by monitoring the duration of device usage, it can automatically display relaxing scenes on an electronic screen to relieve eye fatigue and provide optical massage to relax the eyes.

[0050] Since the homework scenario is played through the glasses display 1, the user does not need to look down or up excessively, ensuring a comfortable writing position to avoid discomfort in the cervical and spinal spine.

[0051] Example 2: Anti-fatigue electronic glasses for learning, see [link / reference] Figure 3 In this embodiment, the shooting component 6 is movably connected to the outside of the glasses display 1, and the relative position between the shooting component 6 and the glasses display 1 can be adjusted; it includes the glasses display 1 and a strap component 2 detachably connected to the glasses display 1 for wearing;

[0052] When a user is doing homework, they first wear the glasses display 1 through the strap component 2. The shooting component 6 is used to capture the scene of the real homework in real time, specifically including the image of the table, textbook, pen and hand. The glasses display 1 is used to project the scene of the real homework, specifically including the image of the table, textbook, pen and hand.

[0053] For details, see Figure 3 , Figure 5 , Figure 7 To effectively solve the problem of lens 4 being compressed due to excessively small focal length, and to reduce the focusing pressure of eyeball 3 and the compression of lens 4, the glasses display 1 includes a housing 101 and an inner housing 102 installed inside the housing 101. One end of the housing 101 is detachably equipped with a shooting component. A high-definition miniature display screen 10 is fixedly installed on one side of the inner housing 102, and a support plate 104 is installed on the side of the inner housing 102 away from the high-definition miniature display screen 10. Two circular grooves are symmetrically opened on one side of the support plate 104, and a convex lens 7 is fixedly installed in each of the two circular grooves.

[0054] The video image played on the high-definition miniature display screen 10 is affected by the convex lens 7 to generate a virtual distant view image. The external environment is captured by the shooting component and played on the high-definition miniature display screen 10. This can effectively solve the problem of lens 4 being compressed due to the small focal length, effectively reduce the focusing pressure of the eyeball 3 and the compression of the lens 4, and effectively avoid ciliary body fatigue caused by long-term compression of the lens, thereby avoiding myopia.

[0055] In addition to using the aforementioned optical technologies to relax the ciliary body of the eye, virtual reality technology can also magnify the font in the exercise book displayed in the scene, making it easier for people to see clearly and also relaxing the eyes.

[0056] Furthermore, by monitoring the duration of device usage, it can automatically display relaxing scenes on an electronic screen to relieve eye fatigue and provide optical massage to relax the eyes.

[0057] Further, see Figure 5 , Figure 6 To facilitate adjustment of the shooting angle, the shooting component includes a front cover 110. Two cameras 111 are symmetrically mounted on the side of the front cover 110 away from the outer shell 101, and two extension ears 112 are symmetrically mounted on the side of the front cover 110 facing the outer shell 101. A groove is centrally located at one end of each side of the outer shell 101, and a fastening bolt 113 is threaded into each groove. A through slot is centrally located on one side of each extension ear 112 for the fastening bolt 113 to pass through. The shooting component captures images of the external environment, which are then played back on a high-definition miniature display screen 10. During shooting, the two fastening bolts 113 can be loosened to rotate the front cover 110 with the two extension ears 112, thereby adjusting the orientation of the cameras 111. After adjustment, the two fastening bolts 113 are tightened again to fix the front cover 110, thus adjusting the shooting component 6 to a suitable position. It is convenient to use and easy to operate.

[0058] Since the scene of doing homework is captured by the downward-flipping camera component 6 and played on the glasses display 1, the user must keep his back straight to see the homework, which solves the problem of students hunching over while doing homework for a long time and affecting their posture.

[0059] Further, see Figure 3 , Figure 5 , Figure 7To improve wearing comfort, extension rods 106 are centrally located on both sides of the inner shell 102, and a fixing sleeve 107 is constructed at one end of the extension rods 106 extending out of the outer shell 101. The strap assembly 2 includes a restraint strap 201, with both ends of the restraint strap 201 respectively installed in the two fixing sleeves 107. A top strap 202 is centrally fixed between the top of the restraint strap 201 and the top of the inner shell 102. Both sides of the restraint strap 201 are fixedly installed to the support arm 203, and an earphone is fixedly installed at one end of the support arm 203. 204. One end of the inner shell 102 is detachably mounted with a face frame 108, and a support pad 109 is glued and fixed on one side of the face frame 108. The glasses display 1 can be fixed to the user's head and positioned on the side of the user's eyes by the binding strap 201 and the top strap 202. After fixing, the position of the two headphones 204 can be adjusted and moved to the ears to play music. After wearing, the support pad 109 on the face frame 108 will relieve the pressure of the inner shell 102 on the face, and the wearing comfort is high.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
