Description

Technical Field

[0001] The present invention relates to the technical field of myopia prevention and control, and specifically to a wearable myopia prevention and control device and a prevention and control method. Background Art

[0002] With the widespread use of electronic devices, especially the popularity of smart phones, computers and other devices, the incidence of myopia among adolescents and adults has shown an increasing trend year by year. Myopia has become an important public health issue worldwide, seriously affecting people's quality of life and daily activities. Although there are some myopia prevention and control devices on the market, such as smart glasses and vision training equipment, they still have some shortcomings in practical applications, especially in terms of wearing stability and comfort, which are difficult to meet the needs of users, especially for long-term use.

[0003] Most of the current myopia prevention and control devices rely on fixing devices to act directly on the head, and are usually fixed to the user's head or nose bridge by means of elastic brackets, frames or straps. However, many existing devices are prone to loosening or shifting during actual wear, especially when the user is engaged in daily activities or exercise, the device is difficult to stably maintain in the preset position, thus affecting the effectiveness of the myopia prevention and control function. In addition, due to the unreasonable design of the contact between the device and the head, users often feel uncomfortable during wearing. Long-term wearing can easily lead to a sense of pressure on the nose bridge, ears and back of the head, which in turn causes fatigue and even discomfort symptoms such as headaches, making it difficult for users to persist in using it, affecting the prevention and control effect.

[0004] On the other hand, existing myopia prevention and control equipment usually lacks personalized adjustment functions for different users. For example, different users have obvious differences in head shape, interocular distance, facial structure, etc. Existing equipment has poor adaptability in these aspects and cannot be accurately adjusted according to the specific needs of users, especially in terms of interocular distance and wearing comfort. Therefore, in actual use, many users find that the device cannot fit their face, resulting in inaccurate visual distance detection or light monitoring, further weakening the prevention and control effect of the device.

[0005] Therefore, the market urgently needs a wearable myopia prevention and control device that can be stably fixed on the head, is highly comfortable, and can be personalized for different users. Summary of the invention

When the light is too dark, the viewing distance is too close, or the eye use time is too long, the corresponding vibrator will issue a reminder to help the user adjust the eye use habits in time. This function helps prevent the eyes from working under unfavorable conditions for a long time, and effectively prevents and controls the occurrence and development of myopia.

[0036] 3. Strong adaptability and support for personalized adjustment. The device is specially designed with personalized adjustment functions for different users. Through the inflation and deflation adjustment of the pressure regulating component and the adjustment motor in the distance and posture adjusting component, the device can be accurately adjusted according to the personalized needs of different users such as head shape and interocular distance, ensuring a good fit between the device and the user's face. Whether it is teenagers, adults or users with different head shapes, they can flexibly adjust the device according to their own needs to ensure the adaptability and effectiveness of the device among different users.

[0037] 4. Air pressure control, adjustable pressure. The device achieves pressure regulation on the nose, ears and back of the head through the combination of air pump and airbag. Through the control of the microprocessor, the airbag can be accurately inflated and deflated, and the pressure of each supporting part can be flexibly adjusted to avoid the pressure or discomfort caused by long-term wearing.

[0038] In general, the wearable myopia prevention and control device provided by this scheme can not only effectively solve the shortcomings of existing devices in terms of wearing stability and comfort, but also help users adjust their eye behavior in a timely manner through intelligent monitoring and reminder functions, further improving the effect of myopia prevention and control. At the same time, the personalized adjustment design of the device ensures its adaptability to different users, giving it a wide range of application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0042] See also Figure 1-2 , 5, 7, a wearable myopia prevention and control device includes a wearing part 1 and a detection part and a warning part assembled on the wearing part 1.

[0043] The wearing part 1 includes: a mounting seat 11, two sets of adjustment brackets 12 respectively mounted on both sides of the mounting seat 11, protective glasses 13 respectively mounted on the bottom of the two sets of adjustment brackets 12, two sets of support legs 14 respectively connected to the rear of the two sets of adjustment brackets 12, two sets of connecting seats 15 respectively fixed to the rear of the two sets of support legs 14, and support bars 16 respectively mounted on the two sets of mounting seats 11.

[0044] The detection part includes a light intensity detection unit 21, a viewing distance detection unit 22, and an eye use time detection unit 23. The light intensity detection unit 21 and the viewing distance detection unit 22 are fixedly installed on the front side of the mounting seat 11, and a group of eye use time detection units 23 are fixedly installed on both groups of adjustment brackets 12.

[0045] It also includes a distance adjustment component 4 and a posture adjustment component. The distance adjustment component 4 is assembled in the mounting seat 11 and is dynamically connected to the two groups of adjustment brackets 12. The two groups of connecting seats 15 are each equipped with a posture adjustment component, and the posture adjustment components are dynamically connected to the support bars 16 on the corresponding side.

[0046] The wearing part 1 is used to wear the myopia prevention and control device as a whole on the head and effectively position it to ensure that the detection part can effectively use the eyes, and the warning part will make corresponding prompts based on the detection results to achieve the purpose of myopia prevention and control.

[0047] The mounting seat 11 can not only ensure the stable installation of the adjustment bracket 12, but also be fixedly supported on the nose, while the connecting seat 15 can be erected on the ear, and through the setting of the supporting legs 14 and the mounting seat 11, the adjustment bracket 12 equipped with the protective glasses 13 can be stably arranged in front of the eyes.

[0048] The distance between the two sets of adjustment brackets 12 and the protective glasses 13 thereon is adjusted through the distance adjustment component 4 so that the two sets of protective glasses 13 can be opposite to the two eyes respectively. The protective glasses 13 can be selected according to different usage scenarios, such as sunshade glasses, blue light protection glasses, or corresponding myopia glasses can be prepared for people with certain myopia symptoms.

[0049] The support bar 16 assembled on the rear of the connecting seat 15 can be retracted and flipped by the corresponding posture adjustment component, so that the support bar 16 can be stuck in the back of the head and cooperate with the mounting seat 11 and the connecting seat 15 to achieve stable wearing of the myopia prevention and control equipment on the head.

[0050] The light intensity detection unit 21 uses a light intensity sensor to measure the light intensity of the surrounding environment, so that the user can use the eyes in a well-lit and appropriate environment, avoiding myopia or aggravation of myopia caused by long-term use of the eyes in an environment with excessive or insufficient light intensity.

[0051] The viewing distance detection unit 22 uses an infrared distance sensor to detect the distance between the glasses and the object being viewed. The eye use time detection unit 23 uses an infrared optical sensor to perform eye tracking and detect the user's eye movement and line of sight direction. When the user stares at one direction (such as a mobile phone, computer screen or book) for a long time, this period of eye use time can be recorded to avoid eye fatigue caused by maintaining the same distance for a long time, and to avoid myopia or aggravation of myopia caused by excessive viewing distance.

[0052] In order to ensure that the detection unit and the warning unit can be stably installed and coordinated for operation and to achieve the design requirements for myopia prevention and control, the following technical solutions are provided.

[0053] The warning part includes a vibrator A31, a vibrator B32, and a vibrator C33. The vibrator A31 is fixedly mounted on the rear side of the mounting seat 11, and the inner sides of the two groups of connecting seats 15 are respectively fixedly mounted with the vibrators B32 and C33.

[0054] It also includes a microprocessor assembled inside the mounting base 11, and the microprocessor maintains signal connection with the vibrator A31, the vibrator B32, the vibrator C33, the light intensity detection unit 21, the viewing distance detection unit 22, and the eye usage time detection unit 23.

[0055] The microprocessor can adopt the Nordic Semiconductor NRF52 series, which excels in low power consumption and wireless communication, and is suitable for wearable devices for myopia prevention and control.

[0056] Data such as light intensity, viewing distance and eye use time detected by the detection unit can be transmitted to the microprocessor, which analyzes and processes the data and controls the vibrators A31, B32 and C33 to remind the user based on whether the analysis results exceed the designed set threshold, thereby effectively preventing and controlling myopia for the user.

[0057] An installation groove 111 is opened on the front side of the mounting seat 11 , and the infrared distance sensor serving as the sight distance detection unit 22 is fixedly installed in the installation groove 111 . A mounting sleeve 121 is fixedly connected to the adjustment bracket 12 , and the infrared optical sensor is fixedly installed in the mounting sleeve 121 . Example

[0058] See also Figure 3-6 In order to ensure that the mounting seat 11 can effectively support and position above the nose, and to ensure that the protective glasses 13 can be assembled on the adjustment bracket 12 in a detachable manner, the following technical solution is provided.

[0059] A V-shaped base 112 is fixedly connected to the bottom of the mounting base 11, a U-shaped slot 122 is provided at the bottom of the adjustment bracket 12, the protective mirror 13 includes a mounting frame 131 and a lens 132 fixed in the mounting frame 131, and an assembly groove 133 is provided on the outer edge of the mounting frame 131 to be nested and matched with the U-shaped slot 122.

[0060] The V-shaped holder 112 can cooperate with the bridge of the nose to achieve stable installation of the mounting seat 11 on the nose.

[0061] The U-shaped slot 122 is combined with the assembly slot 133 on the mounting frame 131, and the protective lens 13 is fixedly installed in the U-shaped slot 122 through a buckle assembly. The lens 132 can be selected according to the user's personal requirements.

[0062] In order to ensure that the adjustment bracket 12 and the distance adjustment component 4 can be stably installed in the mounting seat 11, and to ensure that the adjustment component can accurately adjust the distance between the two groups of adjustment brackets 12, the following technical solution is provided.

[0063] The mounting seat 11 is provided with a mounting cavity 113 and a mounting slot 114 . The inner end of the adjustment bracket 12 is fixedly connected with a sliding bracket 123 . The sliding brackets 123 on the two groups of adjustment brackets 12 are arranged in opposite directions. Both groups of sliding brackets 123 are slidably mounted in the mounting slot 114 .

[0064] The pitch adjustment component 4 includes an adjusting screw 41, an adjusting motor A42, a driving shaft 43, and a matching combination of a worm wheel A44 and a worm A45. The adjusting screw 41 is rotatably installed in the installation slot 114. The adjusting screw 41 is provided with two sections of thread grooves arranged in opposite spiral directions. The two sections of thread grooves are respectively screwed to two groups of sliding brackets 123. The adjusting motor A42 is fixedly installed in the installation cavity 113. The driving shaft 43 is rotatably installed in the installation cavity 113 and the installation slot 114. The worm A45 is fixedly connected to the output shaft of the adjusting motor A42. The worm wheel A44 and a driving bevel gear A431 are fixedly connected to the driving shaft 43. The adjusting screw 41 is fixedly connected to a transmission bevel gear A411 that meshes with the driving bevel gear A431.

[0065] The setting of the mounting cavity 113 and the mounting groove 114 can ensure that the sliding bracket 123 on the adjusting bracket 12 and the distance adjusting component 4 are stably installed in the mounting seat 11, and ensure that the distance adjusting component 4 can drive the two groups of distance adjusting components 4 to always maintain synchronous and symmetrical movement, thereby realizing precise adjustment of the distance between the two groups of adjusting brackets 12.

[0066] When the distance adjustment component 4 is running, the control adjusting motor A42 drives the worm A45 to rotate, and then drives the worm wheel A44 and the driving shaft 43, and the driving bevel gear A431 to operate. The driving bevel gear A431 drives the transmission bevel gear A411 and the adjusting screw 41 to operate stably, and the adjusting screw 41 drives the two groups of sliding brackets 123 to maintain opposite and synchronous operation, so as to adjust the spacing of the adjusting brackets 12.

[0067] The combination of the worm wheel A44 and the worm A45 has the characteristics of deceleration and torque increase and one-way self-locking. The power output by the adjusting motor A42 can be decelerated and torque increased through the combination of the worm wheel A44 and the worm A45 to drive the driving shaft 43 and the adjusting screw 41 to operate stably, and the power can only be transmitted to the worm wheel A44 in one direction through the worm A45. When the adjusting motor A42 is stopped, the worm A45 stops rotating, and then the driving shaft 43 and the adjusting screw 41 can be locked to ensure that the two sets of adjusting brackets 12 are kept at a specific spacing for stable use. Example

[0068] See also Figure 1-2 , 7-10, in order to ensure that the support leg 14 can be stably connected to the adjustment bracket 12, and to ensure that the posture adjustment component can be stably installed in the connecting seat 15 and realize the dynamic connection with the support bar 16, the following technical solution is provided.

[0069] The support leg 14 is hinged to the adjustment bracket 12 , and an assembly cavity 151 is defined in the connection seat 15 , in which an assembly bracket 152 is fixedly connected.

[0070] The posture adjustment component includes an installation sleeve 51, a connecting rod 52, a spline shaft 53, a driving spur gear 54, an adjusting motor A42, and an adjusting motor B55 arranged in the assembly cavity 151. The installation sleeve 51 is coaxially fixedly connected with the connecting rod 52. The connecting rod 52 is plugged into the connecting seat 15 in a relatively rotating and sliding manner. The support bar 16 is fixedly connected to the connecting rod 52. A spline groove 511 is opened at the axis center of the installation sleeve 51. The spline shaft 53 is rotatably installed on the assembly bracket 152 and is slidably plugged into the spline groove 511. A plurality of groups of annular racks 512 are evenly fixedly connected to the outer wall of the installation sleeve 51. The driving spur gear 54 is rotatably installed on the assembly bracket 152 and is meshed with the annular rack 512. The adjusting motor B55 and the adjusting motor C56 are both fixedly installed on the assembly bracket 152. The adjusting motor C56 and the adjusting motor C56 are respectively connected to the spline shaft 53 and the driving spur gear 54 for power.

[0071] The support leg 14 is connected to the adjustment bracket 12 in a hinged manner, which facilitates the overall bending of the support leg 14, the connecting seat 15, and the support bar 16 to achieve the overall folding of the myopia prevention and control equipment and reduce the storage space.

[0072] The arrangement of the assembly cavity 151 and the assembly bracket 152 in the connecting seat 15 can ensure the stable installation of the posture adjustment component. By means of the adjusting motor C56 to drive the driving spur gear 54 to operate, the installation sleeve 51 provided with the annular rack 512 can be driven to telescopically move along the axial direction, and then the support bar 16 can be driven to telescopically move through the connecting rod 52.

[0073] During the telescopic movement of the mounting sleeve 51, the spline groove 511 inside it always maintains a sliding connection with the spline shaft 53, ensuring that the power of the adjusting motor C56 is stably transmitted to the mounting sleeve 51 through the spline shaft 53. When the mounting sleeve 51 is in any telescopic posture, the adjusting motor C56 can drive the spline shaft 53 and the mounting sleeve 51 to rotate around the axis, and then drive the support bar 16 to rotate synchronously through the connecting rod 52.

[0074] The design of the annular rack 512 can ensure that the mounting sleeve 51 remains meshed with the driving spur gear 54 when the mounting sleeve 51 is rotated to any posture.

[0075] By adjusting the coordinated operation of motor B55 and motor C56, the support bar 16 can be driven to adjust the extension and rotation posture so that the support bar 16 can be arranged to abut against the back of the head for support, thereby ensuring that the wearable part 1 is stably supported and worn on the head.

[0076] In order to ensure that the adjusting motor B55 can achieve power connection with the spline shaft 53 and ensure that the adjusting motor B55 drives the spline shaft 53 to operate stably, the following technical solution is provided.

[0077] A worm B551 is fixedly connected to the output shaft of the adjustment motor B55. The posture adjustment component also includes a worm wheel B571 and a driving bevel gear B572 which are rotatably mounted on the assembly bracket 152 and are coaxially fixed thereto. The worm B551 and the worm wheel B571 are in a matching combination. A transmission bevel gear B531 is fixedly connected to the spline shaft 53 and is meshed with the driving bevel gear B572.

[0078] When the adjusting motor B55 drives the worm gear B551 to rotate, the power can be decelerated and torqued and transmitted to the turbine B, and then the transmission bevel gear B531 and the spline shaft 53 are driven to operate stably through the driving bevel gear B572.

[0079] At the same time, the combination of turbine B and worm gear B551 also has a one-way self-locking characteristic. When the adjusting motor B55 is in the shutdown state, the worm gear B551 is in a stationary state, and the worm wheel B571 and the driving bevel gear B572 and the spline shaft 53 are in a locked state and cannot receive external power to rotate, thereby ensuring that the support bar 16 is in a stable posture.

[0080] In order to ensure that the regulating motor C56 can achieve power connection with the driving spur gear 54 and keep the regulating motor C56 driving the driving spur gear 54 to operate stably, the following technical solution is provided.

[0081] A worm C561 is fixedly connected to the output shaft of the regulating motor C56, and a worm wheel C541 is fixedly connected to the axis of the driving spur gear 54, and the worm wheel C541 is meshed with the worm C561.

[0082] When the adjusting motor C56 drives the worm C561 to rotate, the power can be reduced in speed and torque increased and transmitted to the turbine C, thereby driving the driving spur gear 54 to operate stably, and then driving the annular rack 512 and the mounting sleeve 51 to telescopically move along the axial direction.

[0083] The combination of the worm wheel C541 and the worm C561 also has a one-way self-locking feature. When the adjustment motor C56 is in the shutdown state, the worm C561 is stationary, and the worm wheel C541, the driving spur gear 54, and the mounting sleeve 51 are all in a locked state and cannot receive external power for telescopic movement, thereby ensuring that the support bar 16 is in a stable posture.

[0086] The airbag A63 can be in direct contact with the nose, and the pressure on the nose can be adjusted by controlling the inflation and deflation of the airbag A63 to ensure the comfort of the nose.

[0087] When inflating, the air pump A61 is controlled to work and the electromagnetic switch valve A613 is in the open state. At this time, the air in the environment can be filtered through the air inlet filter A62 and transported to the air bag A63 along the air inlet pipe A611 and the air outlet pipe A612 to increase the pressure on the nose. When deflation, the electromagnetic switch valve a631 is controlled to be in the open state, and the air filled in the air bag A63 can be released to reduce the pressure on the nose.

[0092] Airbag B73 can be in direct contact with the ear, and airbag C74 can be in indirect contact with the back of the head. The comfort of the ear and the back of the head can be achieved by controlling the inflation and deflation of airbags B73 and C74.

[0093] When inflating, the air pump B71 is controlled to work. When specifically controlling the inflation of the airbag B73, the solenoid switch valve B714 is controlled to open. At this time, the air in the environment is filtered through the air intake filter B72 and then transported to the airbag B73 along the air intake pipe B711 and the air outlet pipe B712 to increase the pressure on the ear. When deflation, the solenoid switch valve b731 is controlled to open to deflate the air filled in the airbag B73 and reduce the pressure on the ear.

[0094] When specifically controlling the inflation of the airbag C74, the solenoid switch valve C715 is controlled to open, and the filtered air can be delivered to the airbag C74 through the outlet pipe C713, the air inlet cover 75, the connecting hole A532, the spline groove 511, and the connecting hole B521 to increase the pressure on the back of the head. When deflation is performed, the solenoid switch valve c741 is controlled to open, and the air filled in the airbag C74 is released to reduce the pressure on the back of the head.

[0095] In order to prevent air from leaking from the connection between the spline shaft 53 and the spline groove 511 when the airbag C74 is inflated, a sealing rubber ring may be installed at the end of the mounting sleeve 51.
