Description

Technical Field

[0001] This utility model relates to the field of vision protection technology, and in particular to a vision protector. Background Technology

[0002] With the increasing incidence of myopia among teenagers, protecting eyesight while reading and using electronic devices such as tablets and mobile phones has become an important research direction for eye health. Existing methods for protecting eyesight still mainly focus on correcting the user's posture, including traditional brackets that forcibly correct the user's body posture to ensure the correct viewing distance, and wearable devices that monitor the user's body posture and provide timely reminders.

[0003] Traditional eyeglasses have low market acceptance due to their poor flexibility and low user comfort. Wearable devices, on the other hand, have better market acceptance due to their ease of use. They are typically worn on the user's head in the form of glasses or headphones, monitoring the user's eye use through sensors and providing voice or vibration alerts when the user's viewing distance is too close or their posture is incorrect. For example, patent document CN215729151U discloses a smart anti-myopia audio glasses, including a main body comprising a frame and temples, a main board, a distance sensor, a gyroscope sensor, and a Bluetooth audio component. The main board is located inside the temples, while the distance sensor and gyroscope sensor are respectively located on the frame and electrically connected to the main board. The Bluetooth audio component is located inside the temples and electrically connected to the main board. The temples also have a sound receiving hole and a sound output hole corresponding to the Bluetooth audio component. The distance sensor and gyroscope sensor can detect the user's eye use and provide voice reminders when the viewing distance is too close or the posture is incorrect, providing sufficient vision protection for children's daily learning and entertainment. While these wearable devices are generally well-received, their lack of mandatory protection makes it difficult for users to maintain a proper sitting posture for extended periods when reading or using electronic devices. As time goes on, users gradually relax their posture and fail to adjust it promptly even when prompted by voice, leading to a decrease in the device's protective effectiveness.

[0004] To address the problems existing in the aforementioned wearable devices, patent document CN220474140U provides an intelligent vision protector system, including: a controller, an automatic distance adjustment module, an intelligent dimming module, a voice broadcast module, a display module, and a power circuit. The automatic distance adjustment module, intelligent dimming module, voice broadcast module, and display module are electrically connected to the controller, and the controller, automatic distance adjustment module, intelligent dimming module, voice broadcast module, and display module are all electrically connected to the power circuit. The automatic distance adjustment module allows the microcontroller to control a stepper motor to move the electronic device based on the distance between the user and the electronic device, thus achieving automatic distance adjustment. The intelligent dimming module allows the microcontroller to control an LED light to automatically dim based on the ambient illuminance. Through automatic distance adjustment and automatic dimming, the user is placed in a healthy visual environment, thereby protecting the user's eyes and preventing myopia. However, the technical solution provided in this patent document only discloses the relevant electronic control system and still lacks a practical and feasible mechanical structure product to realize the corresponding functions.

[0044] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0046] This utility model embodiment provides a vision protector, including a head-mounted device 1 and a desktop device 2, specifically:

[0047] Head-mounted device 1 is used to collect the rotation angle of the user's head.

[0048] Desktop device 2, such as Figure 1 and 2 As shown, it includes a base plate 21, a column 22, a rotating assembly 23, and a reading shelf 24.

[0049] The column 22 is vertically mounted on the base plate 21, and the reading rack 24 is connected to the top of the column 22 through the rotating assembly 23. The reading rack 24 is used to carry reading materials.

[0050] The desktop device 2 is communicatively connected to the head-mounted device 1. The rotating component 23 drives the reading shelf 24 to rotate according to the rotation angle, so that the angle between the reading plane of the reading shelf 24 and the user's line of sight is kept within a healthy range.

[0051] Specifically, the reading shelf 24 for holding reading materials can be a flat panel, a frame formed by multiple interlocking strips, or a frame formed by a combination of strips and a flat panel. The reading surface of the reading shelf 24 refers to the surface used to place the reading material. The reading material can be a book, tablet computer, mobile phone, or other device that the user needs to view or read. The healthy range of the angle between the reading surface and the user's line of sight is typically 70° to 90°.

[0052] In a more specific implementation scheme, such as Figure 2 As shown, the reading shelf 24 includes a cross body 241 composed of two vertically fixed strips. Each end of the cross body 241 is provided with a raised edge 242 to prevent the reading material from slipping. The raised edge 242 can also be replaced by a clamping component that can directly fix the reading material.

[0053] Specifically, the rotation angles collected by the head-mounted device 1 include: the horizontal rotation angle of the user's head with the vertical direction as the rotation axis, or the pitch rotation angle of the user's head with the horizontal straight line as the rotation axis. The rotation component 23 in the desktop device drives the reading shelf 24 to rotate at the same angle as the rotation angle of the user's head, so that the reading plane is always perpendicular to the user's line of sight, thereby ensuring the user's eye health.

[0054] In a preferred embodiment of this invention, the head-mounted device 1 includes a head-mounted structure and a rotation angle sensor disposed on the head-mounted structure; the rotation angle sensor is used to acquire the rotation angle of the user's head when the user's head rotates. Specifically, the rotation angle sensor may be a gyroscope or a tilt sensor, and the rotation angle sensor may be fixedly disposed inside the head-mounted structure.

[0055] Specifically, such as Figure 3 As shown, the headband structure is an ear-hook structure, including an arc-shaped part 11 for surrounding the user's head, and two ends of the arc-shaped part 11 are respectively provided with protrusions 12 for hanging the arc-shaped part 11 on the user's ears.

[0056] Specifically, to monitor the user's viewing distance, the head-mounted device may also include a distance sensor 13, which is disposed at the end of the arcuate portion 11 of the head-mounted structure and is used to collect the reading distance between the user's head and the reading plane of the reading holder 24. When the head-mounted device is worn on the user's head, the distance sensor 13 is oriented in the same direction as the user's face to make the reading distance data collected by the distance sensor 13 more accurate.

[0057] Corresponding to the rotation angle and reading distance of the user's head collected by the head-mounted device 1, in another preferred embodiment of this invention, the rotating component 23 includes a horizontal rotating part, a first motor, a pitch rotating part, and a second motor 2333.

[0058] The horizontal rotating part includes a base 231 and a turntable 232. The base 231 is fixedly connected to the top of the column 22, and the turntable 232 is rotatably mounted on the base 231. The turntable 232 is used to directly or indirectly support the reading shelf 24. The output end of the first motor is connected to the turntable 232. When the first motor drives the turntable 232 to rotate, it causes the reading shelf 24 to rotate around the axis of the turntable 232. Specifically, the rotation angle of the turntable 232 can be the same as the horizontal rotation angle of the user's head.

[0059] The tilt and rotation unit includes a bearing 233 and a tilt bracket 234. The bearing 233 is fixedly connected to the turntable 232, and the tilt bracket 234 is rotatably connected to the bearing 233. The reading shelf 24 is connected to the tilt bracket 234. The output end of the second motor 2333 is connected to the tilt bracket 234. When the second motor 2333 drives the tilt bracket 234 to rotate, it drives the reading shelf 24 to rotate around the axis of the bearing 233. Specifically, the angle at which the tilt bracket 234 drives the reading shelf 24 to rotate can be the same as the tilt rotation angle of the user's head.

[0060] Specifically, such as Figure 4 As shown, the bearing 233 includes a fixedly connected support column 2331 and a horizontal shaft cylinder 2332.

[0061] The support column 2331 is fixedly connected to the turntable 232. The horizontal shaft cylinder 2332 is a cylindrical shell closed at both ends. The first end of the cylindrical shell is provided with a first connecting hole, and the second end is provided with a second connecting hole. The second motor 2333 is fixedly installed inside the horizontal shaft cylinder 2332. The output end of the second motor 2333 extends to the outside of the horizontal shaft cylinder 2332 through the first connecting hole.

[0062] The pitch support 234 includes a first leg 2341 and a second leg 2342 clamped at both ends of the horizontal shaft cylinder 2332; the second leg 2342 is provided with a connecting shaft 2343 on the side facing the horizontal shaft cylinder 2332, and the second leg 2342 is rotatably connected to the second end of the horizontal shaft cylinder 2332 through the connecting shaft 2343; the first leg 2341 is connected to the output end of the second motor 2333 through a connecting pin 2344, and the connecting pin 2344 is fixedly connected to the first leg 2341.

[0063] In response to the reading distance collected by the aforementioned head-mounted device, and to ensure that the user's viewing distance remains within a healthy range, in another preferred embodiment of this invention, such as... Figure 1 and 2 As shown, the desktop device also includes a linear module 25 that is communicatively connected to the head-mounted device, and the column 22 is connected to the base plate 21 through the linear module 25.

[0064] The linear module 25 includes a third motor, a track 251, and a slider 252 slidably disposed on the track 251. The track 251 is fixedly disposed on the base plate 21, and the slider 252 is fixedly connected to the bottom of the column 22.

[0065] The output end of the third motor is connected to the slider 252. When the third motor drives the slider 252 to move, it causes the reading stand 24 to move closer to or further away from the user according to the reading distance. Specifically, the distance and direction of the slider's movement can be the same as the direction and distance of the user's head movement.

[0066] It should be noted that the first motor, second motor 2333, and third motor used in this embodiment are all stepper motors, servo motors, or servo motors with rotation angle holding function, so that the rotating component 23 can maintain the angle after driving the reading holder 24 to rotate a certain angle until the user's head rotates again. In this embodiment, the process of the first motor, second motor 2333, and third motor responding according to the horizontal rotation angle, pitch rotation angle, and reading distance can be implemented based on conventional technical means such as controllers in the field. This embodiment does not involve any improvement or use of computer programs, but only provides the components, positions, and connection relationships of the head-mounted device and the desktop device.
