Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, specifically to a smart lens holder and myopia control glasses. Background Technology

[0002] Many glasses for preventing and correcting myopia have appeared on the market, but they have several drawbacks, such as: 1. The lenses used are photochromic or pattern-changing liquid crystal lenses, with insufficient initial light transmittance, causing blurred vision after wearing the glasses; 2. They simply use distance sensors to detect distance, and the sensors fail when children tilt their heads or lie on the table with books in front of them; 3. They cannot comprehensively detect whether the learning conditions are adequate, such as the lighting environment, posture, and duration of study. Therefore, glasses that can effectively prevent strabismus and myopia have appeared on the market.

[0003] In related technologies, a type of eyeglasses that can effectively prevent strabismus and myopia includes an eyeglass frame and an intelligent control system. The intelligent control system is located on the frame. When the user's posture is incorrect, the intelligent control system causes the liquid crystal molecules on the lenses to change their state to a foggy state, in order to remind the user to adjust their posture, thereby achieving the effect of myopia prevention. However, since the intelligent control system is located inside the eyeglass frame, the user needs to purchase the entire eyeglasses and the intelligent control system. If the user develops myopia or the degree of myopia changes, they need to buy new anti-myopia glasses with the corresponding prescription, which will result in high costs for the user. At the same time, the adaptability of this anti-myopia glasses is not high.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application proposes an intelligent eyepiece and myopia control glasses.

[0006] Firstly, a smart mounting plate adopts the following technical solution:

[0007] A smart eyeglass holder includes an eyeglass holder body and a liquid crystal lens. The eyeglass holder body is detachably connected to an external eyeglass holder. The liquid crystal lens is disposed on the eyeglass holder body and corresponds to the lens on the external eyeglass holder body. The eyeglass holder body is provided with a smart control system, which is connected to the liquid crystal lens to switch the liquid crystal lens from a transparent state to a fogged state.

[0008] Preferably, the hanging body is provided with a strong magnetic block, which is used to attract the eyeglasses body so that the hanging body is connected to the eyeglasses body.

[0009] Preferably, the intelligent control system includes a main control chip, a three-axis accelerometer, a boost circuit, and a battery embedded in the mounting plate body. The three-axis accelerometer is electrically connected to the main control chip and is used to detect the pitch angle of the mounting plate body. The boost circuit is electrically connected to the main control chip and the liquid crystal lens, and the battery is electrically connected to the main control chip.

[0010] Preferably, the intelligent prevention and control system further includes a laser ranging module installed on the mounting plate body. The laser ranging module is electrically connected to the main control chip and is used to detect the distance between the mounting plate body and the external target object.

[0011] Secondly, a type of myopia control glasses employs the following technical solution:

[0012] A myopia control glasses includes a smart clip and a glasses body. The smart clip is detachably installed on the glasses body, and the glasses body is provided with a lens corresponding to the liquid crystal lens.

[0013] Preferably, the glasses body is provided with a magnet, and the intelligent prevention and control system further includes a Hall sensor, which is used to sense the magnetic field of the magnet in order to activate the intelligent prevention and control system.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. When using this smart lens holder, first place it on the glasses body so that the liquid crystal lens aligns with the lens holder on the glasses body to avoid affecting the normal use of the glasses. At this time, the Hall sensor in the smart prevention and control system will sense the magnetic field of the magnet, causing the main control chip to enter standby mode. When the user's posture is incorrect, the main control chip controls the boost circuit to output a drive voltage, causing the liquid crystal lens to change from a transparent state to a fogged state to alert the user and achieve the prevention and control effect. When the smart lens holder is not needed, it can be directly removed from the glasses body. This design, by making the smart lens holder detachable, allows it to be used by users who are already nearsighted for prevention and control, and can also be used on glasses without a prescription, allowing the smart lens holder to be used separately from the glasses, making it suitable for more situations and thus helping to improve the adaptability of the smart lens holder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] This application discloses an intelligent hanging plate 1. (Refer to...) Figures 1 to 4The smart eyeglass holder 1 includes a holder body 11 and a liquid crystal lens 12. Specifically, the holder body 11 is detachably connected to the outer eyeglass holder 2. An intelligent control system 13 is installed on the holder body 11. The liquid crystal lens 12 is mounted on the holder body 11, and two liquid crystal lenses 12 are spaced apart, corresponding to the lenses of the eyeglass holder 2. In this embodiment, the liquid crystal lens 12 is made of PDLC (polymer dispersed liquid crystal), PNLC (polymer network liquid crystal), or host-guest liquid crystal (GHLC) material. These materials have high transparency (>90%) when no power is applied, ensuring the liquid crystal lens 12 has high transparency and meets optical light transmission requirements. Furthermore, when a sufficiently high voltage is applied to the liquid crystal lens 12... When subjected to current or direct current, liquid crystal molecules scatter, causing the liquid crystal lens 12 to change from a transparent state to a fogged state, thus achieving a blocking effect. The intelligent control system 13 in the hanging body 11 is electrically connected to the liquid crystal lens 12, causing the liquid crystal lens 12 to change state. Therefore, when the user's posture is not correct, the intelligent control system 13 will apply voltage to the liquid crystal lens 12, causing the liquid crystal lens 12 to change to a fogged state, thereby prompting the user and achieving the control effect. By making the intelligent hanging 1 detachable, the intelligent hanging 1 can be used with different glasses, and the glasses can be either plano glasses (without prescription) or myopia glasses, so that the intelligent hanging 1 can be used by different users, improving the applicability of the intelligent hanging 1.

[0024] In some embodiments, a strong magnetic block 111 is provided on the hanging body 11. Two sets of strong magnetic blocks 111 are provided, and the two sets of strong magnetic blocks 111 are respectively provided on both sides of the two liquid crystal lenses 12. When the smart hanging 1 is installed on the glasses body 2, the two sets of strong magnetic blocks 111 will attract with the glasses body 2 so that the smart hanging 1 is firmly installed on the glasses body 2. When it is necessary to remove it, it is only necessary to pull the smart hanging 1 off with force.

[0025] In some embodiments, the intelligent control system 13 includes a main control chip 131, a triaxial accelerometer 132, a boost circuit, and a battery 134. Specifically, the main control chip 131, the triaxial accelerometer 132, the boost circuit, and the battery 134 are all disposed in the mounting plate body 11. The main control chip 131 preferably uses a low-power Bluetooth chip. The triaxial accelerometer 132 is a high-precision sensor and is electrically connected to the main control chip 131. The main control chip 131 is used to receive and process data from the triaxial accelerometer 132. The triaxial accelerometer 132 can continuously monitor the mounting plate body 11, i.e., the acceleration and tilt angle of the user's head in three-dimensional space. The pitch angle of the head relative to the horizontal plane can be calculated through a specific algorithm. The boost circuit is controlled by the main control chip 131, and the battery 134... 4. In this embodiment, a small rechargeable lithium battery 134 or a button battery 134 can be used to power the entire intelligent control system 13. Since the battery 134 belongs to the micro battery 134 series, the voltage it provides is low and insufficient to drive the liquid crystal lens 12. Therefore, a boost circuit is set to boost the voltage output by the battery 134 to the driving voltage required by the liquid crystal lens 12. So, at the user's head tilt angle, for example, when the main control chip 131 calculates the user's head tilt angle, if the angle is less than the preset angle threshold, such as 60°, the main control chip 131 will determine that it is a bad sitting posture. At this time, the main control chip 131 controls the boost circuit to work, generate the required high driving voltage and apply it to the liquid crystal lens 12. The liquid crystal lens 12 changes from a highly transparent state to a highly scattering fogged state in milliseconds to prompt the user to adjust their sitting posture.

[0026] In some embodiments, the intelligent prevention and control system 13 further includes a laser ranging module 135. The laser ranging module 135 is disposed in the mounting plate body 11 and electrically connected to the main control chip 131. In this embodiment, the laser ranging module 135 is preferably a VCSEL (vertical cavity surface emission laser) type, which has the characteristics of small size, high precision and low power consumption. The laser ranging module 135 continuously or periodically emits laser light downwards and forwards and receives the reflection to accurately measure the distance between the liquid crystal lens 12 and the object in front. The main control chip 131 analyzes the ranging data in real time. If the ranging distance is less than the distance threshold, such as 30cm, it will be determined that the viewing distance is too close. The main control chip 131 will also control the boost circuit to make the liquid crystal lens 12 turn into a fogging state. Through the joint detection of the laser ranging module 135 and the triaxial accelerometer 132, the head angle and reading distance of the user are monitored at the same time, so as to cover poor sitting posture as much as possible and play a role in myopia prevention and control.

[0027] This application also discloses a myopia control glasses, including the aforementioned smart clip 1 and glasses body 2. The smart clip 1 is detachably connected to the glasses body 2 via a strong magnetic block 111. The glasses body 2 is provided with lenses corresponding to two liquid crystal lenses 12. These lenses can be non-prescription or prescription, depending on the user's situation. At the same time, a strong magnetic block 111 can also be provided on the glasses to attract the strong magnetic block 111 on the clip body 11.

[0028] In addition, in this embodiment, the intelligent prevention and control system 13 also includes a Hall sensor 136, which is electrically connected to the main control chip 131. At the same time, a magnet 21 is provided on the glasses body 2. The Hall sensor 136 is used to detect the magnet 21 on the glasses body 2. When the Hall sensor 136 detects the magnetic field emitted by the magnet 21, it will send a signal to the main control chip 131 to make the entire system enter a low-power standby state. Through automatic control, power consumption can be reduced when not in use.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
