Description

Technical Field

[0001] This utility model relates to the field of vision testing equipment technology, specifically to a multifunctional EPD vision testing instrument. Background Technology

[0002] Currently, most vision testing devices on the market are lightbox-style structures. Lightbox-style vision testing devices have the following drawbacks: 1. They have reflective properties, affecting the testing results. Additionally, the fixed testing screen makes it impossible to comprehensively test various aspects of vision (such as myopia, color weakness, color blindness, astigmatism, glaucoma, etc.); 2. They have limited functionality; manual testing is labor-intensive; and they cannot quickly provide insights into vision problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional EPD vision tester to replace the current manual testing, making the test more efficient and intelligent.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multifunctional EPD vision tester includes an EPD display screen, an aluminum frame, and a back cover. The EPD display screen is connected to the front end of the aluminum frame. The back cover is fixed to the back of the aluminum frame. A control motherboard is located inside the space enclosed between the back cover and the aluminum frame. The EPD display screen is electrically connected to the control motherboard and can switch between displaying different vision test images. The upper part of the aluminum frame is equipped with a camera, microphone, speaker, and infrared sensor, all electrically connected to the control motherboard. The camera is used to capture images of the face and gestures, the microphone is used to receive the person's voice, the speaker is used to play audio, and the infrared sensor is used to detect the distance between the person and the EPD display screen. A network module is connected to the control motherboard, and this network module communicates with an AI cloud server.

[0006] Furthermore, the back panel of the EPD display screen is connected to the front end of the aluminum frame via a pivot mechanism, which allows the EPD display screen to be rotated to a horizontal or vertical orientation.

[0007] Furthermore, the aluminum frame is provided with an LED light panel for providing a light source for the EPD display screen.

[0008] Furthermore, the AI ​​cloud server is equipped with a cloud-based large language model recognition system.

[0009] Furthermore, the control motherboard is connected to a WiFi chipset and a Bluetooth communication group.

[0010] Furthermore, the camera, microphone, and infrared sensor are integrated into the upper front part of the aluminum frame.

[0011] Furthermore, the speaker is located at the upper rear end of the aluminum frame, and the aluminum frame has sound holes arranged in a matrix at the corresponding speaker location.

[0012] This utility model adopts the above technical solution. By integrating a camera, microphone, speaker and infrared sensor, it can interact with users and realize AI intelligent vision detection, replacing the traditional lightbox vision test method, making the test more efficient. Moreover, it can not only test myopia, but also perform other ophthalmological examinations (color weakness, color blindness, astigmatism, glaucoma, etc.). At the same time, the EPD display screen is connected to the main body through a hinge and can rotate to adapt to display test screens of different sizes. Attached Figure Description
