Description

Technical Field

[0001] The present invention belongs to the technical field of vision training equipment, specifically a self-positioning intelligent vision detection and training instrument and training method, specifically a self-positioning intelligent vision detection and training instrument and training method. Background Art

[0002] Vision restoration refers to the process of reasonably and specifically exercising the ciliary muscles of the eyes, stimulating the growth of optic nerve cells, changing the curvature of the cornea, enhancing the physical condition of the eyes, and improving the damaged naked vision to normal vision.

[0003] Currently, online teaching is booming. Through online courses, online teaching, online tutoring, etc., the teaching efficiency can be greatly improved and teaching time can be saved. However, online teaching has also led to a significant increase in the time that teenagers spend using electronic products. Electronic products such as mobile phones and computers have gradually become an essential part of teenagers' learning. Long-term use of electronic products will cause pressure on the eyes, preventing the eye muscles of teenagers from being trained and extended, thus causing a series of eye diseases such as myopia, strabismus, and astigmatism. Some mild eye diseases can be treated and restored through rehabilitation training. Existing visual rehabilitation training equipment often uses relatively bulky electronic instruments. After being fixed in a certain position, it is often not convenient to move, and patients need to go to a nearby hospital to receive professional treatment. In addition, when patients are performing rehabilitation exercises, due to different heights of patients, the sitting postures of patients are often uncomfortable, affecting the rehabilitation training of patients.

[0004] Currently, the intelligent vision detection and training instrument uses a stepping motor to drive a disc to rotate. However, since the intelligent vision detection and training instrument requires the disc to rotate at an accurate angle to ensure that the "E" character mark directly above the disc is precisely controlled, and there are inevitable mechanical structure errors during the transmission of the stepping motor, the "E" character mark is not always directly above the disc.

[0005] Therefore, the present application proposes a self-positioning intelligent vision detection and training instrument and training method that can precisely control the "E" character mark on the disc to solve the above problems. Summary of the Invention

[0006] The research and development purpose of the present invention is to solve the problem that in the existing intelligent vision training instrument, the "E" character mark on the disc driven by a stepping motor cannot be precisely controlled, resulting in the "E" character mark not always being directly above the disc. A brief overview of the present invention is given below to provide a basic understanding of certain aspects of the present invention. It should be understood that this overview is not an exhaustive overview of the present invention. It is not intended to identify the key or important parts of the present invention, nor is it intended to limit the scope of the present invention.

[0012] Further, a plurality of E-shaped plates are arranged in a circumferential array on the front surface of the turntable. A plurality of iron sheets are correspondingly installed on the back surface of the turntable. The iron sheets arranged on the back of the turntable correspond to one E-shaped plate arranged on the front of the turntable.

[0013] Further, the frame includes a turntable frame, an electromagnet module, and an aluminum square frame. A front flange bearing of the turntable frame and a rear flange bearing of the turntable frame are installed on the turntable frame. The electromagnet module is installed in the groove of the turntable frame. The turntable frame is connected to the aluminum square frame. The aluminum square frame is installed on the bottom shell.

[0014] Further, the infrared laser receiving module includes an upper diffuser, a right diffuser, a lower diffuser, a left diffuser, an upper receiving tube, a right receiving tube, a lower receiving tube, and a left receiving tube.

[0015] Solution 2: A self-positioning intelligent vision detection and training method, which is implemented based on the self-positioning intelligent vision detection and training instrument described in Solution 1, and includes the following two modes:

[0016] Measurement mode: The Mega control board controls the turntable to rotate at a random angle. After the rotation is completed, the user answers through the target interaction module according to the direction of the E-shaped board displayed on the dial. If the direction of the infrared laser receiving module that receives the signal is the same as the direction of the E-shaped board at this time, the recorded score is incremented by one, and the second light bulb lights up. When the received signal and the direction of the infrared laser receiving module are different from the direction of the E-shaped board, the recorded score is decremented by one, and the first light bulb lights up. The E-shaped board on the turntable will conduct five vision measurements for each level. If the current level is less than or equal to one, the measurement will proceed to the previous level. If the obtained score is two, the vision measurement ends, and the user's vision level is the current level minus 0.1. The measurement mode ends.

[0017] Exercise mode: The Mega control board controls the turntable to rotate at a random angle, and randomly switches the E-shaped boards in different levels and directions. The user answers according to the direction of the E-shaped board displayed on the dial through the target interaction module, and the usage data of the user is recorded.

[0018] The present invention has the following beneficial effects:

[0019] 1. The self-positioning intelligent vision detection and training instrument of the present invention solves the problem that the "E" character mark on the turntable cannot be directly above the dial due to mechanical errors in the transmission of the stepping motor when the current intelligent vision detector rotates the disc.

[0048] Measurement mode: The Mega control board 9 controls the turntable 15 to rotate by a random angle. After the rotation is completed, the user answers through the target interaction module according to the direction of the E-shaped plate 151 displayed on the dial 1. If the direction of the infrared laser receiving module 2 that receives the signal is the same as the direction of the E-shaped plate 151 at this time, the recorded score is incremented by one, and the second light bulb 112 lights up. When the received signal and the direction of the infrared laser receiving module 2 are different from the direction of the E-shaped plate 151, the recorded score is decremented by one, and the first light bulb 111 lights up. Five vision measurements will be performed for the E-shaped plate 151 on the turntable 15 for each grade. If the current grade is less than or equal to one, the measurement will be performed in the previous grade. If the obtained score is two, the vision measurement ends, and the user's vision grade is the current grade minus 0.1. The measurement mode ends;

[0049] Exercise mode: The Mega control board 9 controls the turntable 15 to rotate at random angles, randomly switching the E-shaped boards 151 at different levels and in different directions.
