[0033] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] See also Figures 1 to 7 shown. Figure 1 This is a schematic diagram of the structure of a handheld multifunctional automatic vision training device provided in one embodiment of the present application. Figure 1It can be seen that the multifunctional automatic visual training device 10 provided in the embodiment of the present application includes: a shell, which includes a rear shell 101, a middle frame 102 and a face cover 103, the rear shell 101, the middle frame 102 and the face cover 103 are combined to form a disc structure cavity and a handheld structure for accommodating various rotating parts, and the middle frame 102 and the rear shell 101 are installed in a snap-on manner; a rotatable frame bracket 104, which is equipped with at least two groups of lens frames 1041, and the center of which is detachably connected to the motor 107.

[0035] The control module 109 and the motor 107, the control module 109 drives the motor 107 to drive the rotatable frame bracket 104 to rotate back and forth at a certain angle through an algorithm and a structural limit design, and switches the lens frame 1041 in the face cover window 1031. The structural limit design is realized by the cooperation of the middle frame 102 and the rotatable frame bracket 104.

[0036] The handheld multifunctional automatic vision training device can realize multiple different visual function trainings through the combination of three different rotatable components: a rotatable frame bracket, a rotatable red and green lens bracket, and a rotatable baffle. The details are shown in the following table:

[0037]

[0038] In one embodiment, a limiting protrusion is designed inside the shell, and a groove is designed for the rotatable frame bracket according to a predetermined rotation angle. After they are engaged with each other and in limiting contact, the control module detects the current change during the limiting operation and drives the motor in reverse phase to make the rotatable frame bracket rotate back and forth within a predetermined angle range.

[0039] The rotatable red and green film bracket 108 includes a red and green film button 1081. The red and green film button 1081 slides along the arc-shaped hollow sliding groove 1014 in the rear shell 101 to select whether the red and green optical perspective films cover the rear shell window 1012. Specifically, Figure 2 As shown, Figure 2 This is a schematic diagram of the operation of the rotatable red and green sheet support provided in one embodiment of the present application. Figure 2 It can be seen that the red and green button 1081 slides to the left along the arc-shaped hollow sliding groove 1014 in the back shell 101, without covering the back shell window 1012, and performs normal mode training; the red and green button 1081 slides to the right along the arc-shaped hollow sliding groove 1014 in the back shell 101, covering the back shell window 1012, and performs de-inhibition mode training. The purpose of de-inhibition is to enable the amblyopic eye to see objects, and both eyes can see objects together.

[0040] In addition, the rotatable red and green film bracket 108 also includes a rotation center mounting hole, a red and green film frame, and a red and green film window, etc. The rotatable red and green film bracket 108 is installed in the rear shell 101 through the rotation center mounting hole, and the red and green film frame passes through the arc-shaped hollow sliding groove rail 1014 in the rear shell 101 and is screwed to the red and green film button 1081.

Specifically, the rotation center mounting hole, the red and green film frame, and the red and green film window are not marked in the figure.

[0041] The rotatable baffle 105 includes a baffle button 1051, and the baffle button 1051 is used to drive the rotatable baffle 105 to not cover or cover the rear housing window 1012. Specifically, as Figure 3 As shown, Figure 3 The following is a schematic diagram of the operation of a rotatable baffle provided in an embodiment of the present application. Figure 3 It can be seen that the rear housing window 1012 includes a left eye window or a right eye window. When the shielding button 1015 drives the rotatable shielding sheet 105 to not cover the rear housing window 1012, binocular training is performed; when the shielding button 1015 drives the rotatable shielding sheet 105 to rotate rightward to cover the right eye window, monocular left eye training is performed; when the shielding button 1015 drives the rotatable shielding sheet 105 to rotate leftward to cover the left eye window, right eye training is performed.

[0042] In addition, the rotatable baffle 105 also includes a rotation center mounting hole, and the rotatable baffle 105 is assembled on the back of the face cover 103 through the rotation center mounting hole. A limiting protrusion 1023 is provided on the back of the face cover 103 to limit the rotation and positioning of the rotatable baffle 105, so that the baffle button 105 drives the rotatable baffle 105 to rotate to not cover the face cover window 1031 or to cover the face cover window 1031. Specifically, the face cover window 1031 includes a left eye face cover window or a right eye face cover window, and the rotatable baffle 105 can choose to cover the left eye face cover window or the right eye face cover window.

[0043] The cover 103 and the rear shell 101 are both provided with oval windows, which are used to cover the pupil distance adjustment range on the lens frame 1041 respectively. The cover 103 and the middle frame 102 are detachable and can be opened or closed by rotating the fastening buckle 1034 and the anti-fool buckle 1033. Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the cover and the middle frame and a detachable assembly diagram provided by an embodiment of the present application. Figure 4 It can be seen that the upper cover 103 is fastened by rotating the fastening buckle 1034 clockwise, and the upper cover 103 is opened by rotating the fastening buckle 1034 counterclockwise. After opening the upper cover, it is convenient to replace the lens group on the lens frame 1041 and adjust the pupil distance.

Figure 5 It can be seen that at least one limiting protrusion 1013 is provided inside the rear shell 101, and at least one corresponding limiting groove 1044 is provided on the rotatable frame bracket 104. The rotatable frame bracket 104 drives the limiting groove 1044 to rotate at a certain rotation angle, and cooperates with the limiting protrusion 1013 to limit the rotatable frame bracket 104 to rotate back and forth at a certain angle. Figure 5 It can be seen that in this embodiment, a limiting protrusion 1013 is provided inside the rear shell 101, and two corresponding limiting grooves 1044 are provided on the rotatable frame bracket 104. The two limiting grooves and a limiting protrusion are used in conjunction to limit the rotatable frame to rotate at an angle between the two limiting grooves.

[0045] Furthermore, if Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the rotatable bracket and the lens frame provided in an embodiment of the present application, and a diagram for adjusting the pupil distance and separation. Figure 6 It can be seen that the rotatable frame bracket 104 also includes at least two relative lens frames 1041, which are distributed along the radial direction of the rotatable frame bracket 104. The optical center distance between the two relative lens frames 1041 is adjustable, and the two relative lens frames 104 can be used separately or in combination.

[0046] Specifically, Figure 6 As shown, the rotatable frame bracket 104 has a slide rail 1042 with a scale, and the lens frame 1041 has a corresponding serrated slide bar 10411 with a pointer, and the rotatable frame bracket 104 and the lens frame 1041 can be slid apart or combined. The slide rail 1042 with a scale and the serrated slide bar 10411 with a pointer are used together to instruct the user to manually adjust the pupil distance value, thereby improving the feel and accuracy of the adjustment. At the same time, the corresponding set of lens frames 1041 can be slid apart or used in combination to achieve the replacement of the lens frame.

[0047] Furthermore, if Figure 7 As shown, Figure 7 This is a schematic diagram of the control module structure provided by an embodiment of the present application. Figure 7 It can be seen that the control module 109 is used to control the motor 107 to reverse and drive the rotatable mirror frame bracket 104 to automatically rotate back and forth in the disc structure cavity by detecting the limit contact and stall of the housing 100 and the rotatable mirror frame bracket 104.

[0048] In addition, if Figure 7As shown, an operation button 1092 is also provided on the shell, and the control module 109 is also used to respond to the user's operation instructions triggered by the operation button 1092; the operation button 1092 includes at least one of a button for setting the training duration, a button for setting the flipping interval of the lens frame group, a button for setting the manual reversal trigger, a button for setting the query of the last training duration, and a button for setting the flipping number.

[0049] Furthermore, if Figure 7 As shown, the housing also includes a display screen 1091 or a low voltage display LED, and the display screen 1091 is used to display the working state, parameters or query content of the device 10. The low voltage display LED is used to display the working voltage of the device 109.

[0050] Through the above analysis, it can be seen that the multifunctional automatic visual training device provided in the embodiment of the present application further introduces a red and green film rotating bracket, which can effectively avoid the occurrence of inhibition during training and thus affect the training effect, thereby further improving the training effect.

[0051] like Figure 8 As shown, Figure 8 The flowchart of the handheld multifunctional automatic vision training method provided in one embodiment of the present application is shown in FIG. The multifunctional automatic vision training method is applied to a multifunctional automatic vision training device. Specifically, the multifunctional automatic vision training device is as follows: Figures 1 to 7 As shown in any embodiment, detailed description will not be given in this embodiment.

[0052] Depend on Figure 8 It can be seen that the handheld multifunctional automatic vision training method includes:

Specifically, the selected mode includes a manual mode, an automatic mode, or a query mode. The handheld multifunctional automatic vision training device enters the selected mode state based on the user's selected mode.

[0055] In addition, after the handheld multifunctional automatic vision training device enters the power-on state, it detects the battery voltage to ensure that it can provide sufficient working power. Specifically, a low voltage threshold is preset, and when it is detected that the battery voltage is lower than the low voltage threshold, such as 2.4V, the low voltage indicator LED is controlled to flash at a preset interval, such as 5 seconds.

[0056] S802: In response to the mode selected by the user and the parameters set in the current mode, start the corresponding training mode.

[0057] After entering the selection mode, the user is prompted to set parameters. For example, in manual mode, the user can set the training time such as 5 minutes, 10 minutes, 15 minutes or 20 minutes, and the reversal frequency such as 10 times / minute, 15 times / minute, 20 times / minute or 30 times / minute. In automatic mode, the user can also set the training time, but there is no need to set the reversal frequency. In query mode, you can enter by long pressing the query key, and switch to query the training time or number of training times by clicking the query key.

[0058] After selecting the mode and setting the parameters, enter the corresponding mode. Specifically, in manual mode, you can switch to automatic mode by pressing the start button, automatically switch the lens group based on the set reversal frequency, reach the training time or long press the power button to end the training.

[0059] In automatic mode, you can switch to manual mode by pressing the start button. Each time you press the reverse button, the lens group is switched. After the training time is reached, you can end the training by long pressing the power button or by ending the mode without any operation within a certain period of time, such as 2 minutes.

[0060] In the query mode, you can exit the mode by long pressing the query key for a preset time, such as 3 seconds, or by no operation within a certain time, such as 5 seconds.

[0061] S803: If a shutdown command is detected, the shutdown state is entered.

[0062] After finishing training, press and hold the power button or trigger the shutdown command without any operation to enter the shutdown state.

[0063] Through the above analysis, it can be seen that the handheld multifunctional automatic vision training method provided in the embodiment of the present application can respond to the user's operation based on the operation button, select different training modes, and improve the automation of training.
