Description

Technical Field

[0001] This utility model relates to the field of head-mounted vision training devices, and more specifically to a head-mounted vision training device with a detachable lens plate for identifying the type of lens. Background Technology

[0002] Currently, the flip-paddle head-mounted vision training device is one of the most commonly used tools for testing and training visual accommodation function. However, the flip-paddle has significant limitations and can only perform a limited number of tasks. The primary function of the flip-paddle is to train accommodative sensitivity and improve accommodative lag. Secondly, it can be used to train accommodative amplitude and improve accommodative function. However, current flip-paddle devices still have certain limitations:

[0003] 1. Most only have two pairs of lenses, requiring frequent manual lens replacement to meet the training needs of different users, hence the need for a replaceable lens disc structure.

[0004] 2. Most of them are manually flipped lenses, which puts a lot of strain on the hands, and because they are manually controlled, some usage errors are inevitable.

[0005] Meanwhile, current head-mounted visual training devices have relatively limited training programs. Later, replaceable mirror devices were developed to increase the number of training programs. However, this solution has drawbacks, namely, the training programs and logic corresponding to changing mirrors may be prone to errors, and there may be risks such as errors when changing mirrors. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a detachable head-mounted vision training device for identifying the type of mirror disc.

[0007] The objective of this utility model is achieved through the following technical solution.

[0008] A head-mounted visual training device with detachable eyepiece plate type identification includes: a sliding structure on the main frame, within which are corresponding left and right eyepiece plate mounting seats; both the left and right eyepiece plate mounting seats are equipped with interpupillary distance racks; the interpupillary distance racks on the left and right eyepiece plate mounting seats are meshed with interpupillary distance gear knobs; the interpupillary distance gear knobs are rotatably connected to the main frame; both the left and right eyepiece plate mounting seats are equipped with eyepiece plate drive devices; the drive shaft of the eyepiece plate drive device is detachably connected to the corresponding eyepiece plate; each eyepiece plate is equipped with a model identification component, which has one or more identification magnets; and the main frame is equipped with two sets of Hall sensors that match the identification magnets of the two eyepiece plates.

[0009] The eyepiece disk is a circular disc with multiple eyepiece mounting holes. A rotation limiting groove is located at the center of the eyepiece disk. The size and shape of the rotation limiting groove match the structure of the drive shaft connection end of the eyepiece disk drive device. One or more fixing magnets are provided on the rotation limiting groove.

[0010] The rotating limiting groove has a pentagonal structure, and each protruding corner of the rotating limiting groove is equipped with a fixed magnet.

[0011] The through hole at the center of the rotating limiting groove and the eyepiece disk has a stepped hole structure.

[0012] The model identification component has an equilateral triangle structure, with three identification magnets evenly spaced along its long side.

[0013] Each group of Hall sensors consists of 3 units.

[0014] The interpupillary distance gear knob includes a gear part and an adjustment part, which are fixedly connected. The gear part meshes with the interpupillary distance racks provided on the left and right eyepiece disk mounts. The adjustment part is a semi-circular knob with a friction groove at the arc edge.

[0015] The interpupillary distance racks on the left and right eyepiece plate mounts are positioned opposite each other, and the interpupillary distance racks on the left and right eyepiece plate mounts are correspondingly positioned at the upper and lower ends of the interpupillary distance gear knob gear part.

[0016] The left and right eyepiece disk mounts have the same structure, including a mount body, an eye observation element, and an eyepiece disk drive device. The mount body is equipped with an eye observation element and an eyepiece disk drive device. The eyepiece disk drive device is equipped with a stepping motor, which is connected to the drive shaft.

[0017] The beneficial effects of this invention are as follows: This solution improves upon the flip-type head-mounted visual training device. It can automatically switch lenses according to training requirements, using a stepper motor to rotate the eyepiece disk, ensuring a uniform lens switching speed. The interpupillary distance can be manually adjusted according to user needs via an interpupillary distance gear knob.

[0018] Based on this, the device automatically identifies the eyepiece after replacement and allows for direct training without manual confirmation. It can also identify the rotation position of the eyepiece, effectively improving the ability to handle corresponding projects. Attached Figure Description

[0030] The rotation limiting groove 604 has a pentagonal structure, and each protruding corner of the rotation limiting groove 604 is provided with a fixed magnet 605.

[0031] The through hole at the center of the rotating limiting groove 604 and the eyepiece disk 6 is a stepped hole structure.

[0032] The model identification component 601 has an equilateral triangle structure, and three identification magnets 602 are equidistantly arranged on the long side of the model identification component 601.

[0033] Each group of Hall sensors 7 consists of 3 units.

[0034] The interpupillary distance gear knob 5 includes a gear part 501 and an adjustment part 502. The gear part 501 and the adjustment part 502 are fixedly connected. The gear part 501 meshes with the interpupillary distance rack 4 provided on the left eyepiece disk mounting base 2 and the right eyepiece disk mounting base 3. The adjustment part 502 is a semi-circular knob, and a friction groove is provided at the arc edge of the semi-circular knob.

[0035] The interpupillary distance racks 4 on the left eyepiece plate mounting base 2 and the right eyepiece plate mounting base 3 are arranged opposite each other, and the interpupillary distance racks 4 on the left eyepiece plate mounting base 2 and the right eyepiece plate mounting base 3 are respectively set at the upper and lower ends of the gear part 501 of the interpupillary distance gear knob 5.

[0036] The left eyepiece disk mounting base 2 and the right eyepiece disk mounting base 3 have the same structure, including a mounting base body, an eye observation element 8 and an eyepiece disk driving device.
