Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to multilayer independent dye liquid crystal dimming color smart glasses. Background Technology

[0002] With the rapid development of technology, smart wearable devices have gradually integrated into people's daily lives. Among them, smart glasses, as a wearable terminal that frees up the hands, are showing great development potential. Currently, most smart glasses on the market focus on functions such as information prompts, audio-visual entertainment, or sports data recording, and their form and function are still under continuous exploration.

[0003] However, existing smart glasses products still have some shortcomings. In terms of health monitoring, many smart glasses have limited functionality or lack the ability to monitor key physiological indicators such as respiratory rate and blood oxygen saturation in real time without user contact, making it difficult to provide timely warnings when potential changes occur in the user's health. Regarding optical performance, most existing products use ordinary lenses or simple photochromic lenses, preventing users from freely adjusting the lens color according to personal preference or specific environmental needs. Furthermore, the lenses' ability to adapt to ambient light is limited, failing to provide optimal visual protection and comfort in complex and changing lighting environments.

[0004] Furthermore, wearing comfort is a key factor affecting user experience. Due to the integration of batteries, chips, and other electronic components, smart glasses are typically heavier than traditional glasses. Their fixed center of gravity can lead to pressure and discomfort on the bridge of the nose or behind the ears after prolonged wear. Finally, from a maintenance and cost-effectiveness perspective, the lenses of smart glasses are fragile components. Once scratched or damaged, they are often difficult for users to replace easily. High repair costs or the need for complete device replacement shorten the product's lifespan and increase the long-term burden on users. Summary of the Invention

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides multilayer independent dye liquid crystal dimming color smart glasses, comprising:

[0037] The frame 1 and temple 2 are provided. A controller 3 is installed in the middle of the temple 2. A charging port 19 is provided at the bottom of the temple 2. A health monitoring component is installed on the outside of the frame 1. An optical color adjustment component is installed in the middle of the frame 1. A weight adjustment component is installed on the top of the temple 2.

[0038] In this embodiment, the health monitoring component can detect the user's physical condition and provide timely support when the user's physical condition suddenly declines. At the same time, the optical color adjustment component allows the user to adjust the corresponding color filter according to their own preferences, and the weight adjustment component allows the user to adjust the center of gravity of the smart glasses according to their own needs.

[0039] The health monitoring component includes a connecting block 8, a spring pin 14, a nose bridge 9, and a biosensor 15. The connecting block 8 is fixedly connected to the outside of the frame 1, the spring pin 14 is fixedly connected to the middle of the connecting block 8, the nose bridge 9 is rotatably connected to the end of the spring pin 14 away from the connecting block 8, the biosensor 15 is installed in the middle of the nose bridge 9, one end of the biosensor 15 spring pin 14 is in contact with human skin, and a ceramic vibrating plate 16 is fixedly connected to the middle of the nose bridge 9.

[0040] In this embodiment, the health monitoring component includes a connecting block 8, a spring pin 14, a nose bridge 9, and a biosensor 15. The component is installed on the outside of the frame 1 via the connecting block 8. The biosensor 15 can collect key physiological indicators such as the user's respiratory rate, blood oxygen saturation, and body temperature in real time and transmit them to the system for comparative analysis to determine the user's physical condition. At the same time, a ceramic vibrating pad 16 is also fixedly connected to the nose bridge 9. When the subsequent system module determines that the user's health status is abnormal, the system will control the ceramic vibrating pad 16 to vibrate, providing a timely tactile alert to the user. Since one end of the spring pin 14 is connected to the connecting block 8 and the other end is rotatably connected to the nose bridge 9, the nose bridge 9 has a certain degree of extension and movement freedom. This ensures that when the user moves or makes slight movements, the biosensor 15 installed in the middle of the nose bridge 9 can always fit tightly against the user's nose skin, thereby ensuring the continuity and accuracy of data collection.

[0041] The controller 3 has a built-in intelligent health optical control system. The intelligent health optical control system is used to judge the user's physical condition based on the biological information fed back by the biosensor 15. The intelligent health optical control system can also be used to receive external light source information and adjust the optical color adjustment components according to the light source information to protect the user's eyes.

[0042] In this embodiment, the controller 3 integrates a microprocessor and memory, and has a built-in intelligent health optical control system. The charging port 19 and the internal lithium battery enable the controller 3 to power various functions of the glasses, so that the controller 3 can receive and process biological information from the biosensor 15 in the health monitoring component and ambient light information from the optical sensor 4 in the optical color adjustment component. Based on these input information, the intelligent health optical control system can perform analysis and calculation, and output instructions to drive the corresponding components.

[0043] The optical color-tuning assembly includes an optical sensor 4, an OCA optical adhesive 18, an explosion-proof film 5, and multiple GH host-type dye liquid crystals 17. The optical sensor 4 is installed in the middle of the lens frame 1. The multiple GH host-type dye liquid crystals 17 are connected by the OCA optical adhesive 18. An explosion-proof film 5 is installed on the outer side of two of the GH host-type dye liquid crystals 17. An electrode sheet 13 is installed on the side of the multiple GH host-type dye liquid crystals 17 facing the lens frame 1. A locking assembly is installed on the outer side of the explosion-proof film 5.

[0044] In this embodiment, three GH host-guest type dye liquid crystals 17 are precisely bonded together by OCA optical adhesive 18. These are red, green, and blue liquid crystal layers, respectively. Each liquid crystal layer has an electrode plate 13 installed on its outer side, which is attached to the electrode plate 13 inside the lens frame 1. This electrode plate 13 is used to receive electrical signals from the controller 3. By changing the voltage applied to the electrode plate 13, the alignment direction of the liquid crystal molecules can be precisely controlled, thereby changing the light transmittance and color of that liquid crystal layer. Through the superposition of the color effects of each layer, users can customize the filter color of the lens according to their personal preferences. The outermost GH host-guest type dye liquid crystal 17 is provided with an explosion-proof film 5 to enhance its mechanical strength and safety, preventing damage to the GH host-guest type dye liquid crystal 17 due to accidental collisions. At the same time, the optical sensor 4 installed on the lens frame 1 is responsible for detecting the intensity of ambient light and transmitting the data to the system. The system adjusts the brightness of the lens to achieve automatic adjustment, protecting the user's eyes from strong light stimulation.

[0045] The weight adjustment assembly includes a slot 6, a counterweight 7, a rotating rod 20, and a rotating block 21. The slot 6 is located at the top of the temple 2. The rotating block 21 is slidably connected to the middle of the slot 6. The rotating rod 20 is rotatably connected to the middle of the rotating block 21. The counterweight 7 is fixedly connected to the other end of the rotating rod 20 away from the rotating block 21. Multiple rubber strips 22 are fixedly connected to the outside of the rotating block 21, and all of the multiple rubber strips 22 are in contact with the inner wall of the slot 6.

[0046] In this embodiment, the counterweight 7 is connected to the rotating block 21 slidably connected in the slot 6 via the rotating rod 20, so that the user can manually push the counterweight 7 along the slot 6 according to their own wearing habits, thereby changing the center of gravity of the entire smart glasses, making it more inclined towards the bridge of the nose or the ears, so that the user can adjust it according to their own preferences when wearing it. In order to ensure that the adjusted position is stable, multiple rubber strips 22 are fixed on the outer side of the rotating block 21. These rubber strips 22 contact the inner wall of the slot 6 to generate friction, preventing the counterweight 7 from accidentally sliding due to shaking during daily use.

[0047] The locking assembly includes a slide groove 10, a connecting rod 11, a magnetic block 12, a slider 25, a magnetic block 26, and a limiting assembly. The slide groove 10 is located in the middle of the frame 1. The slider 25 is slidably connected to the middle of the slide groove 10. The connecting rod 11 is fixedly connected to the outside of the optical color-correcting assembly. The magnetic block 12 is fixedly connected to the middle of the connecting rod 11. The magnetic block 26 is fixedly connected to the bottom of the slider 25. The top of the slider 25 has a groove 27. When the slider 25 slides toward the middle of the frame 1, the magnetic block 26 will move away from the magnetic block 12 to reduce the magnetic attraction force.

[0048] In this embodiment, under normal installation conditions, magnetic block 12 and magnetic block 26 attract each other, firmly fixing the optical color-correcting component inside the frame 1. When replacement is required, the user can press the groove 27 on the top of the slider 25, thereby pushing the slider 25 to slide in the slide groove 10, which causes magnetic block 26 and magnetic block 12 to be misaligned, significantly reducing the magnetic attraction force. This allows the entire optical color-correcting component to be easily pulled out and replaced, making the operation convenient and tool-free.

[0049] The limiting component includes a limiting block 23 and a limiting groove 24. The limiting block 23 is fixedly connected to the outside of the slider 25. The inner wall of the slide groove 10 is provided with a limiting groove 24, and the slider 25 is slidably connected to the middle of the limiting groove 24.

[0050] In this embodiment, when the user moves the slider 25, it will cause the limiting block 23 to move. The limiting block 23 cooperates with the limiting groove 24. When the slider 25 slides, the limiting block 23 moves within the limiting groove 24, ensuring that the slider 25 can only move smoothly along the preset trajectory, avoiding shaking or jamming, and at the same time preventing the slider 25 from falling.

[0051] The intelligent health optical control system includes:

[0052] The data acquisition module is used to receive biological information, including respiratory rate, blood oxygen and body temperature, fed back by the biosensor 15, receive ambient light information fed back by the optical sensor 4, and receive user control commands from the controller 3.

[0053] The health monitoring and early warning module is used to compare, calculate and analyze biological information to determine the user's physical condition. When it is determined that the user's physical condition has suddenly deteriorated, it controls the ceramic vibrating plate 16 to vibrate to warn the user.

[0054] The optical control module is used to adjust the current output to the electrode plate 13 according to the user's control instructions, and to control the molecular arrangement of multiple GH guest-host type dye liquid crystals 17. The optical control module is also used to automatically adjust the current output to the electrode plate 13 according to the intensity of the ambient light information, thereby changing the brightness effect of the GH guest-host type dye liquid crystal 17.

[0055] In this embodiment, the intelligent health optical control system provided by the present invention may include: a data acquisition module, a health monitoring and early warning module, and an optical control module.

[0056] In one embodiment, the data acquisition module is configured to receive data signals from multiple sensors and user instructions, preprocess and format the data signals, and output structured data to the health monitoring and early warning module and the optical control module.

[0057] Specifically, the data acquisition module is electrically connected to the biosensor 15 to periodically acquire raw signals reflecting the user's physiological state. These raw signals include signals for calculating respiratory rate, photoplethysmography (PPG) signals for calculating blood oxygen saturation, and signals for calculating body temperature.

[0058] For the calculation of respiratory rate R, the data acquisition module uses a preset time window T. w Peak detection is performed on the signal to determine the number of respiratory cycles N. breath The respiratory rate is calculated using the following formula:

[0059]

[0060] Where R is measured in times per minute; N breath For time window T w Total number of respiratory cycles detected internally; T w This is the preset sampling time window, in seconds.

[0061] For calculating blood oxygen saturation (SpO2), the data acquisition module processes the red and infrared PPG signals from biosensor 15. The module extracts the AC and DC components of each signal and calculates the blood oxygen saturation using the Lambert-Beer law and the following formula:

[0062]

[0063] Among them, AC R and DC RThese represent the AC and DC components of the red light signal, respectively; AC IR and DC IR These represent the AC and DC components of the infrared light signal, respectively; A and B are preset coefficients calibrated based on empirical data.

[0064] For measuring body temperature T, the data acquisition module receives an electrical signal V from the temperature sensing unit in the biosensor 15. T And through the preset conversion function f(V) T Convert it to a temperature value in degrees Celsius (°C).

[0065] The data acquisition module is also electrically connected to the optical sensor 4 to receive a raw electrical signal I that is proportional to the intensity of ambient light. L The module converts the electrical signal into a standard illuminance value L in lux using the following formula:

[0066] L=k×I L ;

[0067] Where k is a calibration coefficient preset according to the specifications of optical sensor 4.

[0068] In addition, the data acquisition module receives user control commands from the controller 3. These commands include user-defined target color values, such as RGB values ​​or preset mode selections. The data acquisition module parses the received commands into standardized control parameters.

[0069] After completing the data collection and processing, the data acquisition module sends the calculated structured data packets of respiratory rate, blood oxygen saturation, and body temperature to the health monitoring and early warning module. Simultaneously, it sends the calculated ambient light intensity and the resolved user control parameters to the optical control module.

[0070] In one embodiment, the health monitoring and early warning module is electrically connected to the data acquisition module to receive data and electrically connected to the drive circuit of the ceramic vibrating pad 16 to send control signals. This module is configured to receive structured data from the data acquisition module, analyze it based on a preset health status model, and generate and send an alert signal when a specific change in the user's physical condition is detected.

[0071] The structured data packets received by the health monitoring and early warning module contain values ​​for respiratory rate (R), blood oxygen saturation (SpO2), and body temperature (T). The module's storage unit stores a set of health status reference thresholds, including a lower limit threshold for respiratory rate (R). th_low and upper limit threshold R thhigh Blood oxygen saturation lower limit threshold SpO 2th and the lower limit threshold of body temperature T thlow and upper limit threshold T thhigh.

[0072] This module calculates a comprehensive health status score H. score To quantify the degree of deviation between current physiological indicators and reference states. score The calculation follows the formula:

[0073]

[0074] Where: w R , w T These are the preset weighting coefficients for respiratory rate, blood oxygen saturation, and body temperature, respectively, and are non-negative real numbers; f R (R) is the respiratory rate deviation function; f is the deviation function of blood oxygen saturation; T (T) is the body temperature deviation function.

[0075] When R thlow ≤R≤R thhigh At that time, f R (R) = 0; otherwise, f R (R) is a function that is greater than zero and increases as R deviates from the normal range;

[0076] When SpO2≥SpO 2th hour, otherwise, It is a function that is greater than zero and increases as SpO2 decreases;

[0077] When T thlow ≤T≤T thhigh At that time, f T (T) = 0; otherwise, f T (T) is a function that is greater than zero and increases as T deviates from the normal range.

[0078] After calculating the comprehensive health status score H score Then, the module compares it with a preset alarm trigger threshold H. th Compare them.

[0079] If the comparison result satisfies condition H score >H th If the module determines that the user's physical condition has suddenly deteriorated, the health monitoring and early warning module will generate a high-level warning control signal S. alert The signal is then output to the drive circuit of the ceramic oscillator 16. The drive circuit receives a high-level S signal. alert After the signal, a driving voltage is applied to the ceramic vibrator 16 to cause it to vibrate. If H score ≤H thThe module will then output a low-level signal or remain in a state of no signal output.

[0080] In one embodiment, the optical control module is electrically connected to the data acquisition module to receive data and to the driving circuit of the multiple sets of electrode plates 13 to send control signals. This module is configured to calculate and output voltage signals driving each layer of GH guest-host type dye liquid crystal 17 based on user control commands and ambient light information, thereby controlling the color and brightness of the eyeglass lenses.

[0081] The optical control module receives the ambient light intensity value L and user control parameters from the data acquisition module. The user control parameters include a target color value, represented as a three-dimensional vector C. target =[R in G in B in ], where R in G in B in These correspond to the input values ​​for the red, green, and blue color channels, respectively, and their values ​​range from [0,1]. The optical control module also receives the ambient light intensity value L.

[0082] The module first performs adaptive brightness adjustment. It calculates a global transmittance adjustment factor α based on the ambient light intensity value L. L The calculation of this factor follows a pre-defined nonlinear mapping function g(L), which outputs a value close to 1 when L is low, and decreases as L increases. α L This can be derived from the following formula:

[0083] α L =g(L);

[0084] Where L is the ambient light intensity value, α L The range of values ​​for is [α] min ,1], where α min This is the preset minimum transmittance adjustment factor.

[0085] Next, the module performs color adjustment. It will input the target color value C from the user. target With global transmittance adjustment factor α L Combining these parameters, the final control parameters applied to each layer of the GH guest-host type dye liquid crystal 17 are calculated. For the i-th color channel i∈{R,G,B}, its final target transmittance value T i The calculation is as follows:

[0086] T i =α L ·C in,i ;

[0087] Among them, C in,iThe target color vector C target The value of the i-th component.

[0088] Finally, the optical control module will calculate the target transmittance value T for each channel. i Converted to the corresponding driving voltage V i This conversion is based on the electro-optic response characteristic curves of each GH guest-host type dye liquid crystal 17, which are stored in the module's lookup table or represented by the function h(T). The voltage V output to the driving circuit of the electrode sheet 13 corresponding to the i-th layer of liquid crystal is... i for:

[0089] V i =h(T) i );

[0090] Wherein, h(T) i To achieve the target transmittance T i Mapped to a function of the required driving voltage. The driving circuit operates based on the received voltage value V. i A voltage is applied to the corresponding electrode 13 to control the molecular arrangement of the i-th GH guest-host type dye liquid crystal 17, so that it achieves the target transmittance T. i .

[0091] Working principle: First, when the user puts on the glasses, the biosensor 15 on the nose bridge 9 will come into contact with the user's nose bridge skin, thereby detecting and collecting the user's breathing rate, blood oxygen changes, and body temperature changes, and transmitting them to the intelligent health optical control system. The system compares and calculates to determine the user's physical condition. At the same time, when the user's physical condition suddenly drops, the system will vibrate through the ceramic vibrating pad 16 to improve the user's condition and make them pay attention to their physical condition in time. Furthermore, under the action of the spring pin 14, the nose bridge 9 can always be in close contact with the user's skin during exercise to ensure the accuracy of data collection.

[0092] The user adjusts the output of the intelligent health optical control system via controller 3. Guided by the two sets of electrode plates 13, the system can control the molecular arrangement changes within the GH host-type dye liquid crystal 17. Thus, under the superposition of the color changes of the red, green, and blue GH host-type dye liquid crystal 17, the user can adjust the color of their filter according to their preferences. Furthermore, with the help of optical sensor 4, the intelligent health optical control system can adjust the brightness of the GH host-type dye liquid crystal 17 according to the intensity of ambient light, thereby protecting the user's eyes and avoiding light stimulation. The explosion-proof film 5 also ensures the safety of the GH host-type dye liquid crystal 17, preventing damage caused by collisions.

[0093] Users can adjust the center of gravity of the smart glasses by sliding the counterweight 7 on the temple 2 while wearing the device. This allows users to adjust the center of the smart glasses to be closer to the bridge of the nose or the ears according to their own wearing habits, thereby improving wearing comfort.

[0094] When the GH host-type dye liquid crystal 17 or the frame 1 is damaged due to prolonged use, the user can slide the slider 25 in the middle of the slide groove 10 by pressing the groove 27. This allows the slider 25 to cause the magnetic block 26 to be misaligned and separated from the magnetic block 12 on the connecting rod 11. This allows the explosion-proof film 5 and the GH host-type dye liquid crystal 17 connected to the connecting rod 11 to be quickly pulled out from the middle of the frame 1 for quick replacement, thus reducing unnecessary waste.
