Description

Technical Field

[0001] This utility model relates to the field of intelligent bracket technology, and more specifically to a self-moving bracket for preventing myopia. Background Technology

[0002] With the rapid development of information technology and the transformation of education methods, digital devices such as tablets and e-readers have become important tools for students' learning. However, maintaining incorrect reading posture for extended periods, such as holding the screen or book too close to the eyes, is one of the main reasons for the continued rise in the rate of myopia among students.

[0003] While some vision protection aids exist on the market, such as fixed-height desk stands and vision reminders, these products cannot automatically adjust to the optimal reading distance based on the user's actual usage. Although some products have adjustable functions, their operation is complex, often requiring manual intervention, resulting in a poor user experience and failing to achieve the desired vision protection effect.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] A self-moving anti-myopia bracket, such as Figures 1 to 3 As shown, the device includes a base frame 1, on which are provided: a support member for fixing the screen 9 / book; a distance measuring member 3 for detecting the distance between the base frame 1 and the user; a drive member for moving the base frame 1 back and forth; and a controller 5, which controls the drive member to move the base frame 1 back and forth according to the signal from the distance measuring member 3, thereby maintaining an appropriate distance between the base frame 1 and the user.

[0024] In this embodiment, the controller 5 uses an ESP32 microcontroller. The user can preset the safe reading distance between the base frame 1 and the user in the controller 5. The controller 5 then controls the drive unit to move the base frame 1 within the safe reading distance by detecting the real-time distance between the base frame 1 and the user through the distance measuring device 3. No manual adjustment is required from the user, making it convenient to use.

[0025] The support includes a support plate 201 vertically mounted on the base frame 1, and a support block 202 vertically mounted on the base frame 1 and located in front of the support plate 201. The bottom sides of the support plate 201 are fixed to the sides of the base frame 1. Both the base frame 1 and the support plate 201 are made of aluminum profiles, and the middle of the support plate 201 is an acrylic plate. The support blocks 202 are vertically fixed to both sides of the front end of the base frame 1. When the screen 9 is placed against the support plate 201, the front end of the screen 9 abuts against the support block 202, causing the screen 9 to be tilted, which perfectly meets the user's reading needs and is suitable for various scenarios such as placing tablets, mobile phones, or books.

[0026] The ranging device 3 includes an ultrasonic module fixed to the front end of the base frame 1. The ultrasonic module is connected to the controller 5. When in use, the user sits in front of the base frame 1. Through the reflection of ultrasonic waves, the distance between the base frame 1 and the user can be detected. The ultrasonic module transmits the data signal to the controller 5. In this embodiment, the ultrasonic module used is model HC-SR04.

[0027] The driving component is a wheel 401 located at the bottom of the base frame 1, and also includes a motor 402 fixed on the base frame 1. The wheel 401 is connected to the output shaft of the motor 402, and the motor 402 is connected to the controller 5. The controller 5 controls the motor 402 to rotate forward or backward, thereby controlling the wheel 401 to move forward or backward.

[0028] In this embodiment, a wheel 401 is provided in the middle of the front end of the base frame 1, and two wheels 401 are provided at the rear end, located on both sides of the rear end, so that the three wheels 401 are arranged in a triangular shape. At least the two wheels 401 at the rear end of the base frame 1 are connected to motors 402. The controller 5 synchronously controls the two motors 402, so that the two rear wheels 401 move forward or backward synchronously. The wheels 401 cannot turn, but can only drive the base frame 1 to move back and forth.

[0029] The base frame 1 is equipped with a voice recognition module 6 and a speaker 7. Users can issue commands through the voice recognition module 6, and the voice recognition module 6 will play the sound through the speaker 7 to achieve voice interaction. For example, if the daily timetable is pre-stored, when the user says "Monday timetable", the voice recognition module 6 recognizes the keyword and plays the Monday timetable through the speaker 7. This enables voice interaction for information retrieval, making it a powerful assistant for learning and work.

[0030] In this embodiment, there are two speakers 7, which are distributed on both sides of the base frame 1. Specifically, the speakers 7 are fixed to the back of the support plate 201 and will not affect the placement of the screen 9.

[0031] A battery module 8 is also installed on the base frame 1. The battery module 8 is used to power the entire frame. The battery module 8 can be charged by a data cable using a rechargeable battery, or it can be replaced by a battery. In this embodiment, the controller 5, ultrasonic module, motor 402, voice recognition module 6 and speaker 7 are connected by wires, which are not shown in the figure.

[0032] The working process of this utility model is as follows:

[0033] The user places the screen 9 or books on the support and turns on the power. The ultrasonic module continuously detects the distance between the user and the base frame 1. After receiving the distance information, the controller 5 starts the motor 402 to rotate forward or backward according to the preset safe reading distance. The wheels 401 drive the base frame 1 to move forward or backward, so that the base frame 1 is always kept within the user's safe reading range.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
