Description

Technical Field

[0001] This invention relates to the field of smart wearable and virtual display technology, specifically a portable smart interactive visual communication display device. Background Technology

[0002] With the popularization of near-eye display technology, portable visual communication display devices (such as VR / AR glasses and head-mounted cinemas) have been widely used in entertainment, education, and industrial design. These devices are typically worn on the user's head and use a near-eye optical system to magnify the screen image and project it onto the user's eyes to create an immersive visual experience. However, as application scenarios become more complex, existing technologies still have limitations in terms of structural adjustment accuracy, environmental adaptability, and interactive safety.

[0003] Existing portable display devices primarily rely on manual adjustment or fixed structural designs for wearability. Users often need to repeatedly adjust the lens position manually to find a clear image point. This subjective adjustment method is not only inefficient but also struggles to achieve millimeter-level precision. Especially when the user moves their head or body, the device is prone to slight displacement due to the lack of an active locking mechanism, causing the optical center to deviate from the visual axis. This can lead to blurred images, ghosting, or even visual dizziness, making it difficult to guarantee a consistently stable optimal optical viewing distance.

[0004] In balancing thermal management and optical display, existing devices typically employ a fully enclosed eye mask structure to block external light interference. This design leads to poor air circulation within the internal space, and after prolonged wear, heat and moisture emitted by the body easily condense into fog on the lens surface, severely obstructing vision. Although some existing technologies attempt to incorporate heat dissipation vents in the casing, the lack of an effective separation design between the optical and air paths means that while these direct-flow openings expel hot air, they also allow stray light from the external environment to directly enter the display area, causing decreased image contrast and a washed-out appearance. This fails to achieve both efficient defogging and effective light blocking.

[0005] Furthermore, when using immersive display devices, users' visual and auditory perceptions are primarily focused on virtual content, leaving them relatively isolated from the external physical environment. Existing display devices generally lack mechanisms for perceiving and responding to the external environment. When users move near walls or obstacles, the devices cannot issue timely and effective warnings, easily leading to collisions. Simultaneously, existing human-computer interaction modes are relatively simplistic, often employing fixed voice recognition channels. In noisy public environments or outdoor settings, environmental noise can easily mask user commands or cause misrecognition. There is a lack of a system solution capable of intelligently adjusting interaction strategies and safety logic based on environmental conditions. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a portable intelligent interactive visual communication display device that solves the problems of insufficient accuracy and stability caused by manual adjustment of viewing distance in existing portable display devices, difficulty in effectively preventing external light interference while achieving efficient defogging and heat dissipation in enclosed structures, and safety hazards and weak interactive anti-interference capabilities caused by the lack of environmental perception mechanisms during immersive use.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a portable intelligent interactive visual communication display device, including display glasses, connecting frames fixedly connected to both sides of the display glasses, straps fixedly connected between the connecting frames, sound-emitting components provided on both sides of the straps, a visual sensor electrically connected to the bottom of the display glasses, and a control system mounted on a chip inside the display glasses; The display glasses are fixedly connected to a fixed panel inside. A detection component is provided on one side of the fixed panel. Two limiting rings are fixedly connected to one side of the fixed panel. Each limiting ring is provided with a distance adjustment component. A buffer ring is fixedly connected to one side of the display glasses. Multiple heat dissipation channels are opened inside the buffer ring. Multiple opening and closing components are provided inside the buffer ring.

[0008] Preferably, each of the sound-emitting components includes a connecting rod and a sound-emitting tube. The connecting end of the connecting rod is rotatably connected to the outside of the strap, and one side of the sound-emitting tube is fixedly connected to the bottom end of the connecting rod. The sound-emitting tube is electrically connected to the internal wiring of the connecting rod.

[0009] Preferably, the detection component includes a distance sensor and a temperature sensor, with one end of the distance sensor electrically connected to the top of the outer side of the fixed panel and one end of the temperature sensor electrically connected to the bottom of the outer side of the fixed panel.

[0010] Preferably, each of the distance adjustment components includes a sight mirror mechanism and two sliding mechanisms. The sight mirror mechanism includes a sliding ring and an observation mirror. The outer wall of the sliding ring is slidably connected to the inside of the limiting ring, and the outer wall of the observation mirror is fixedly connected to the inner wall of one end of the sliding ring.

[0011] Preferably, each of the sliding mechanisms includes a limiting post and an electric telescopic rod. One end of the limiting post is fixedly connected to the outer wall of the sliding ring, the fixed end of the electric telescopic rod is fixedly connected to the inside of the limiting ring, and the output end of the electric telescopic rod is fixedly connected to the outer wall of the limiting post.

[0012] Preferably, each of the opening and closing components includes a baffle plate and a micro motor. The baffle plate is rotatably connected to the inside of the buffer ring on both sides, the outer wall of the micro motor is fixedly connected to the inside of the buffer ring, and the output end of the micro motor is fixedly connected to one end of the baffle plate.

[0013] Preferably, the control system includes: The adaptive sight distance adjustment module receives real-time distance data from the distance sensor, compares it with the preset optimal optical sight distance, and generates control commands to drive the electric telescopic pole. The intelligent temperature control defogging module receives real-time temperature data from the temperature sensor and compares it with preset temperature start-up thresholds and preset temperature reset thresholds. Based on the comparison results, it controls the rotation direction and start / stop of the micro motor. The environmental perception safety interaction module is used to receive external environmental data and external audio signals collected by the visual sensor, compare the distance to obstacles with the preset safety warning distance, compare the environmental noise with the preset noise interference threshold, and coordinate the control of display and audio output based on the comparison results.

[0014] Preferably, the specific working logic of the adaptive viewing distance adjustment module is as follows: The preset optimal optical viewing distance is a specific value within the range of 15 mm to 25 mm; The adaptive viewing distance adjustment module calculates the difference between the physical distance value detected by the distance sensor and the preset optimal optical viewing distance. When the absolute value of the difference is greater than 1 mm, it outputs a drive signal to the electric telescopic rod, which drives the observation mirror to move through the sliding ring until the detected physical distance value is equal to the preset optimal optical viewing distance.

[0015] Preferably, the specific working logic of the intelligent temperature control defogging module is as follows: The preset temperature start threshold is set to 35℃; the preset temperature reset threshold is set to 28℃. When the real-time temperature value detected by the temperature sensor is higher than 35 degrees Celsius, the micro motor is triggered to rotate in the forward direction, opening the heat dissipation channel for heat dissipation and defogging. When the monitored real-time temperature drops below 28 degrees Celsius, the micro motor is controlled to rotate in reverse to close the heat dissipation channel.

[0016] Preferably, the specific working logic of the environmental perception safety interaction module is as follows: The preset safety warning distance is set to 0.5 meters to 1.0 meter; the preset noise interference threshold is set to 70 decibels. The visual sensor is used to calculate the relative distance between the user and surrounding obstacles. When the relative distance is less than 0.5 meters to 1.0 meters, a semi-transparent obstacle warning outline is generated and superimposed on the display screen of the display glasses. Simultaneously, the decibel level of ambient noise is detected in real time. When the decibel level exceeds 70 decibels, the voice wake-up function is cut off, and a prompt to switch the interaction mode is displayed on the display glasses interface.

[0017] This invention provides a portable intelligent interactive visual communication display device. It has the following advantages: 1. This invention achieves automated closed-loop precision adjustment of the observation lens position through the cooperation of a distance sensor and an electric telescopic rod inside the limiting ring. The control system calculates the deviation between the user's physical distance to the eye and the preset optimal optical distance in real time. Once the deviation exceeds the set threshold, the sliding ring is driven to make a fine adjustment along the axis, overcoming the precision error of traditional manual adjustment and ensuring that the observation lens is always positioned at the optimal imaging focal plane for different users' facial contours. This improves the clarity of the displayed image while enhancing the structural stability of the device.

[0018] 2. This invention utilizes intelligent temperature control logic combined with a light-gas separation heat dissipation structure to resolve the contradiction between heat dissipation and defogging and light shielding and leakage prevention in enclosed display devices. When internal heat accumulation is detected, a micro motor drives the baffle to open the heat dissipation channel to expel hot air. At the same time, the non-direct-view maze path formed by the baffle and the heat dissipation channel, together with the light-absorbing inner wall, can physically block the straight-line entry of external ambient light. While quickly eliminating lens fog and reducing internal temperature, it also eliminates the problem of decreased display contrast caused by external stray light interference.

[0019] 3. The environmental perception safety interaction module integrated in this invention improves the safety and anti-interference capability of the device in immersive use scenarios. By calculating visual sensor and audio signal data, the system can automatically overlay a visual warning outline when an obstacle approaches a safe distance, and intelligently cut off the voice wake-up channel in high-noise environments. This compensates for the blind spots of environmental perception when the user wears the device, reduces the risk of collision during movement, and avoids misjudgment of commands or invalid interaction caused by noise interference.

[0023] See attached document Figure 1 -Appendix Figure 5 Display glasses 1, with connecting frames 2 fixedly connected to both sides of display glasses 1, and straps 3 fixedly connected between the connecting frames 2, with sound-emitting components on both sides of the straps 3, and a visual sensor 6 electrically connected to the bottom of display glasses 1, and a control system 100 mounted on the chip inside display glasses 1; The display glasses 1 are fixedly connected to a fixed panel 7. A detection component is provided on one side of the fixed panel 7. Two limiting rings 10 are fixedly connected to one side of the fixed panel 7. Each limiting ring 10 is provided with an adjustment component. A buffer ring 15 is fixedly connected to one side of the display glasses 1. Multiple heat dissipation channels 16 are opened inside the buffer ring 15. Multiple opening and closing components are provided inside the buffer ring 15. Each sound-emitting component includes a connecting rod 4 and a sound-emitting tube 5. The connecting end of the connecting rod 4 is rotatably connected to the outside of the strap 3. One side of the sound-emitting tube 5 is fixedly connected to the bottom of the connecting rod 4, and the sound-emitting tube 5 is electrically connected to the internal circuit of the connecting rod 4. The detection component includes a distance sensor 8 and a temperature sensor 9. One end of the distance sensor 8 is electrically connected to the top of the outside of the fixed panel 7, and one end of the temperature sensor 9 is electrically connected to the bottom of the outside of the fixed panel 7. Each distance adjustment assembly includes a sight mirror mechanism and two sliding mechanisms. The sight mirror mechanism includes a sliding ring 11 and an observation mirror 14. The outer wall of the sliding ring 11 is slidably connected to the inside of the limiting ring 10, and the outer wall of the observation mirror 14 is fixedly connected to the inner wall of one end of the sliding ring 11. Each sliding mechanism includes a limiting post 12 and an electric telescopic rod 13. One end of the limiting post 12 is fixedly connected to the outer wall of the sliding ring 11, the fixed end of the electric telescopic rod 13 is fixedly connected to the inside of the limiting ring 10, and the output end of the electric telescopic rod 13 is fixedly connected to the outer wall of the limiting post 12.

[0024] Specifically, in the process of using a portable intelligent interactive visual communication display device, the system first activates the distance sensor 8 located on the outside of the fixed panel 7, enabling it to continuously monitor the actual physical distance between the user's eye surface and the observation lens 14 non-contactly at a high sampling rate, and converts the collected analog signal into a digital signal and transmits it to the control system 100; the control system 100 receives and analyzes the distance data fed back in real time, and quickly calculates the deviation value between the current position and the preset optimal imaging focus through the internal processor, and then generates the corresponding driving voltage command and sends it to the electric telescopic rod 13 embedded in the internal cavity of the limiting ring 10; the electric telescopic rod 13 responds to the command to perform a linear telescopic feed action, and rigidly drives the sliding ring 11 and the observation lens 14 fixed on its inner wall through the mechanical transmission structure, so that it performs linear displacement along the axial trajectory; this closed-loop adjustment process continues to run until the real-time monitored distance value converges to the optimal optical viewing distance range, thereby realizing millimeter-level stepless precision viewing distance matching for different users' facial undulation features, and using the holding torque of the electric transmission mechanism to ensure the optical stability and structural stability of the device during wearing and interaction.

[0025] See attached document Figure 3 Appendix Figure 6 and attached Figure 7 The detection components include a distance sensor 8 and a temperature sensor 9. One end of the distance sensor 8 is electrically connected to the top of the outer side of the fixed panel 7, and one end of the temperature sensor 9 is electrically connected to the bottom of the outer side of the fixed panel 7. Each opening and closing component includes a baffle plate 17 and a micro motor 18. The two sides of the baffle plate 17 are rotatably connected inside the buffer ring 15, the outer wall of the micro motor 18 is fixedly connected inside the buffer ring 15, and the output end of the micro motor 18 is fixedly connected to one end of the baffle plate 17.

[0026] Specifically, a temperature sensor 9, which is closely attached to the inner surface of the fixed panel 7, performs high-frequency thermal environment sampling on the relatively enclosed space formed by the buffer ring 15 and the face, and converts the monitored temperature values ​​into digital signals in real time and transmits them to the control system 100. When the control logic determines that the real-time temperature exceeds the preset defogging start threshold, the system immediately sends a drive pulse to the micro motor 18, which drives the baffle 17 to produce a precise angular or linear displacement through the shaft of the micro motor 18, thereby opening the heat dissipation channel 16 preset in the buffer ring 15. At this time, the physical form of the baffle 17 after opening and the internal structure of the heat dissipation channel 16 together constitute The non-direct-viewing labyrinthine airflow path utilizes the thermal convection driving force and pressure gradient generated by the internal and external temperature difference to guide the high-temperature and high-humidity gas accumulated in the cavity to diffuse rapidly outward along a tortuous path, disrupting the conditions for fog condensation on the surface of the observation mirror 14. At the same time, the geometry of this labyrinthine structure, combined with the light-absorbing coating on the inner wall of the channel, creates an optical trap. By utilizing the principle of rectilinear propagation of light, it forces external incident light to undergo multiple ineffective reflections at the corners of the channel and be absorbed step by step. This physically cuts off the direct path for external ambient light to enter the internal display area, ensuring gas exchange efficiency while preventing the reduction in image contrast caused by external stray light.

[0027] See attached document Figure 8 The control system 100 includes: The adaptive sight distance adjustment module 101 is used to receive real-time distance data fed back by the distance sensor 8, compare it with the preset optimal optical sight distance, and generate control commands to drive the electric telescopic pole 13 to move. The intelligent temperature control defogging module 102 is used to receive real-time temperature data fed back by the temperature sensor 9, compare it with the preset temperature start threshold and the preset temperature reset threshold, and control the rotation direction and start / stop of the micro motor 18 according to the comparison result. The environmental perception safety interaction module 103 is used to receive external environmental data and external audio signals collected by the visual sensor 6, compare the distance to obstacles with the preset safety warning distance, compare the environmental noise with the preset noise interference threshold, and coordinate the control of display and audio output based on the comparison results. The specific working logic of the adaptive viewing distance adjustment module 101 is as follows: The preset optimal optical viewing distance is a specific value within the range of 15 mm to 25 mm; The adaptive viewing distance adjustment module 101 calculates the difference between the physical distance value detected by the distance sensor 8 and the preset optimal optical viewing distance. When the absolute value of the difference is greater than 1 mm, it outputs a drive signal to the electric telescopic rod 13, which drives the observation mirror 14 to move through the sliding ring 11 until the detected physical distance value is equal to the preset optimal optical viewing distance. The specific working logic of the intelligent temperature control defogging module 102 is as follows: The preset temperature start threshold is set to 35℃; the preset temperature reset threshold is set to 28℃. When the real-time temperature value detected by the temperature sensor 9 is higher than 35 degrees Celsius, the micro motor 18 is triggered to rotate in the forward direction, opening the heat dissipation channel 16 for heat dissipation and defogging. When the monitored real-time temperature value drops below 28 degrees Celsius, the micro motor 18 is controlled to rotate in reverse to close the heat dissipation channel 16. The specific working logic of the environmental perception and safety interaction module 103 is as follows: The preset safety warning distance is set to 0.5 meters to 1.0 meter; the preset noise interference threshold is set to 70 decibels. The visual sensor 6 calculates the relative distance between the user and surrounding obstacles. When the relative distance is less than 0.5 meters to 1.0 meters, a semi-transparent obstacle warning outline is generated and superimposed on the display screen of the display glasses 1. Simultaneously, the decibel level of ambient noise is detected in real time. When the decibel level exceeds 70 decibels, the voice wake-up function is cut off, and a prompt to switch the interaction mode is displayed on the Glasses 1 interface.

[0028] Specifically, this invention provides a control system 100 for a portable intelligent interactive visual communication display device. This control system 100 is integrated into a chip inside the display glasses 1. It is connected via circuitry to a visual sensor 6, a distance sensor 8, a temperature sensor 9, and a signal acquisition unit in the sound output assembly. Control signals are sent to the electric telescopic rod 13, the micro motor 18, the display unit of the display glasses 1, and the sound output tube 5. The control system 100 includes an adaptive viewing distance adjustment module 101, an intelligent temperature control defogging module 102, and an environmental perception safety interaction module 103.

[0029] The adaptive distance adjustment module 101 is used to perform precise calibration of the distance between the viewing mirror 14 and the user's eye. The adaptive distance adjustment module 101 is electrically connected to the distance sensor 8, periodically... (For example, 50ms) is the sampling interval, receiving real-time physical distance data collected by distance sensor 8. The system's internal storage unit is set with a preset optimal optical viewing distance. This value is set as a constant in the range of 15 mm to 25 mm (e.g., 20 mm), which corresponds to the optical exit pupil distance of the observation lens 14.

[0030] The adaptive sight distance adjustment module 101 calculates the real-time displacement deviation according to the following formula. : ; in, This represents the measured distance from sensor 8 at the current moment. The optimal optical viewing distance preset for the system; The absolute value symbol is used to unify the judgment logic. The adaptive viewing distance adjustment module 101 will calculate the deviation. Compared with the system's preset dead zone threshold (Set to 1 mm) for comparison.

[0031] When the condition is met At this time, the adaptive viewing distance adjustment module 101 generates a drive signal and sends it to the electric telescopic rod 13. Upon receiving the drive signal, the electric telescopic rod 13 performs a telescopic action, causing the sliding ring 11 connected to the limiting post 12 to move axially along the connecting rod 4. The displacement of the sliding ring 11 directly changes the position of the observation mirror 14 relative to the user's face. The adaptive viewing distance adjustment module 101 continues to execute the above formula calculation until the conditions are met. At this point, the drive signal is stopped, and the observation mirror 14 is locked in the optimal imaging position.

[0032] The intelligent temperature-controlled defogging module 102 manages the thermal and light environments inside the buffer ring 15. The intelligent temperature-controlled defogging module 102 communicates with the temperature sensor 9 to obtain real-time temperature values ​​inside the buffer ring 15. The system is set with a preset temperature threshold for activation. Set the preset temperature reset threshold to 35 degrees Celsius. It is 28 degrees Celsius.

[0033] When the condition is met When the intelligent temperature-controlled defogging module 102 determines that there is a risk of internal heat accumulation or fogging, it immediately outputs a positive voltage to the micro motor 18. The micro motor 18 rotates and drives the baffle plate 17 to deflect, opening the heat dissipation channel 16. At this time, the hot air inside the buffer ring 15 is discharged through the heat dissipation channel 16, and the physical structure of the baffle plate 17 blocks external light from shining in a straight line. When the intelligent temperature-controlled defogging module 102 detects that the real-time temperature value meets the requirements... When the voltage is reversed, it outputs a reverse voltage to the micro motor 18, driving the shield 17 to reset and close the heat dissipation channel 16 to maintain the stability of the internal environment and prevent dust from entering.

[0034] The environmental perception and safety interaction module 103 processes external environmental information and coordinates human-computer interaction logic. Connected to the vision sensor 6, the module acquires real-time image data of the external environment. This module utilizes an image depth algorithm to calculate the relative distance between surrounding obstacles and the user. The system is set with a preset safety warning distance. The distance is between 0.5 meters and 1.0 meter. When the conditions are met... At that time, the environmental perception safety interaction module 103 generates a corresponding semi-transparent obstacle warning outline and transmits the image signal to the display driving circuit of the display glasses 1.

[0035] The environmental perception safety interaction module 103 is also connected to the audio acquisition unit to collect sound signals from the external environment. This module calculates the sound pressure level of the ambient noise using the following formula. : ; in, The root mean square voltage value of the acquired audio signal; The reference voltage value; This is a calibration constant related to microphone sensitivity; This is a base-10 logarithmic function used to convert linearly changing voltage ratios into a logarithmic scale (decibels) that conforms to the characteristics of human hearing. The calculated... This refers to the current ambient decibel level. The system has a preset noise interference threshold. It is 70 decibels.

[0036] When the condition is met At this time, the environmental perception safety interaction module 103 executes the interaction mode switching logic: blocking the signal input of the voice recognition channel to prevent misjudgment of commands; sending commands to the display glasses 1 to pop up a prompt message for switching the interaction mode on the graphical interface; and adjusting the audio gain or output mode of the sound output tube 5 to adapt to the hearing needs in a high-noise environment.

[0037] Working principle: When using a portable intelligent interactive visual communication display device, the distance sensor 8 detects the physical distance between the user's eyes and the viewing mirror 14 in real time. The control system 100 drives the electric telescopic rod 13 fixed inside the limiting ring 10 to extend and retract based on the feedback data. This causes the viewing mirror 14 to slide smoothly along the electric telescopic rod 13 using the sliding ring 11, thereby automatically adjusting to the optimal optical viewing distance. This achieves stepless precision viewing distance matching and stable wearing protection for users with different facial contours.

[0038] The temperature sensor 9, which is fixed on the surface of the fixed panel 7, continuously monitors the internal temperature. When the temperature rises or there is a risk of fogging, the micro motor 18 is triggered to drive the shield 17 to change its state and open the heat dissipation channel 16. The shield 17 and the heat dissipation channel 16 form a labyrinth-like airflow path. Using the principle of aerodynamics, hot air is quickly discharged and fogging of the observation mirror 14 is eliminated. At the same time, the light-absorbing coating inside blocks the direct light from entering the interior, solving the problem of light leakage that easily leads to a decrease in image contrast in traditional breathable structures.

[0039] The system uses a visual sensor 6 to scan the external environment in real time. When it detects obstructions or potential collision hazards, it does not cut off the virtual screen, but instead overlays a semi-transparent obstacle warning outline onto the display content of the display glasses 1. At the same time, the system analyzes the ambient noise level in real time through relevant audio components. When it determines that the ambient noise affects the recognition of voice commands, it automatically suppresses the voice input channel and prompts the user to switch the interaction mode through the display glasses 1. At the same time, it adjusts the audio output strategy of the speaker 5, thereby achieving dual protection for the wearer's safety and interaction efficiency in complex environments.

9. A portable intelligent interactive visual communication display device according to claim 7, characterized in that, The specific working logic of the intelligent temperature control defogging module (102) is as follows: The preset temperature start threshold is set to 35℃; the preset temperature reset threshold is set to 28℃. When the real-time temperature value detected by the temperature sensor (9) is higher than 35 degrees Celsius, the micro motor (18) is triggered to rotate in the forward direction, and the heat dissipation channel (16) is opened for heat dissipation and defogging. When the monitored real-time temperature value drops below 28 degrees Celsius, the micro motor (18) is controlled to rotate in the opposite direction to close the heat dissipation channel (16).

10. A portable intelligent interactive visual communication display device according to claim 7, characterized in that, The specific working logic of the environmental perception safety interaction module (103) is as follows: The preset safety warning distance is set to 0.5 meters to 1.0 meter; the preset noise interference threshold is set to 70 decibels. The visual sensor (6) is used to calculate the relative distance between the user and the surrounding obstacles. When the relative distance is less than 0.5 meters to 1.0 meters, a semi-transparent obstacle warning outline is generated and superimposed on the display screen of the display glasses (1). At the same time, the decibel value of the ambient noise is detected in real time. When the decibel value exceeds 70 decibels, the voice wake-up function is cut off, and the interactive mode is switched on the display glasses (1) interface.
