[0032] like Figures 1 to 7 As shown, this application provides intelligent navigation glasses for the blind, including a frame 1, lenses 2 and temples 3, and also includes an intelligent assistive system module 4 disposed on the frame 1;
[0033] The intelligent auxiliary system module 4 includes a main control chip 41, a visual environment perception module 42, a motion detection path navigation module 43, a voice interaction module 44, a wireless communication remote connection module 45, and a real-time feedback module 46.
[0034] In this embodiment, the eyeglass frame 1, lens 2, and temple 3 are the basic physical structure of the entire smart blind glasses, providing support and wearing functions. The eyeglass frame 1 ensures the stability and comfort of the glasses by supporting and fixing the lens 2, while the temple 3 ensures that the glasses can be stably worn in the user's ear area during use.
[0035] The main control chip 41 is preferably an STM32F103RCT6 MCU with a Cortex-M3 core. It supports multiple GPIO inputs and outputs and has five built-in serial communication ports. It supports multiple communication protocols and multiple timers, providing core processing capabilities for the system. As the core of the entire system, the main control chip 41 is responsible for managing and coordinating the work of all modules, processing information from various sensors and user input, and making decisions. The visual environment perception module 42 is responsible for perceiving and analyzing the user's surrounding environment, including information on obstacles, roads, pedestrians, etc., providing the user with accurate environmental data and enhancing the spatial perception capabilities of the glasses. The motion detection path navigation module 43 is mainly responsible for monitoring the user's motion status, including steps, direction, speed, etc., and providing navigation guidance based on the user's actual location and target location. The voice interaction module 44 provides voice feedback and voice input interaction methods for blind users. The system enables interaction with users, providing guidance, prompts, and necessary feedback. The wireless communication remote connection module 45 is responsible for connecting with external devices or cloud platforms to obtain real-time information and conduct remote communication, such as accessing maps, traffic data, and public facility information, thereby enhancing the intelligence and practicality of the glasses. The real-time feedback module 46 provides real-time feedback to users based on the analysis results of the intelligent module, including voice prompts and vibration feedback, helping users understand the surrounding environment, path conditions, and potential obstacles, thereby improving navigation accuracy and coping with complex environments. It can also monitor the user's movement posture in real time, while enhancing interaction capabilities and improving environmental perception capabilities, further overcoming many technical limitations of existing blind glasses.
[0036] like Figure 3 and Figure 7 As shown, the visual environment perception module 42 includes a binocular camera 421 and a laser rangefinder 422. The binocular camera 421 is located inside the lens 2.
[0037] In this embodiment, the binocular camera 421, by configuring two lenses, mimics human binocular vision and can acquire depth information of objects, perceive the distance between objects and the glasses, the shape and size of objects, and detailed information about the surrounding environment. It is connected to the main control chip 41 through a specific pin and is powered by a 5V power supply. The laser rangefinder 422 measures distance by emitting a laser beam and receiving the reflected light signal. It has high precision and high reliability and is more suitable for detecting distant objects or for precise positioning in complex environments. The laser rangefinder 422 preferably uses an STP-23 single-point ranging module, which is directly connected to the microcontroller to collect data. It has a built-in high-frequency laser ranging module and communicates through the PB10 and PB11 pins of the main control chip 41.
[0038] like Figure 7 As shown, the motion detection path navigation module 43 includes a three-axis gyroscope 431 and a GPS module 432, both of which are installed inside the eyeglass frame 1.
[0039] In this embodiment, the three-axis gyroscope 431 uses an MPU6050 chip, supports the IIC communication protocol, and is connected to the transmit and receive lines PB6 and PB7 of the USART1 of the main control chip 41 to detect whether the user is in a normal walking state and protect users with mobility impairments. The GPS module 432 uses a NEO-7M GPS module for device positioning and real-time synchronization of latitude and longitude information, and communicates through the PC10 and PC11 pins of the main control chip 41.
[0040] like Figure 4 and Figure 7 As shown, the language interaction module 44 includes a bone conduction headset 441, which is located on the outside of the temple 3.
[0041] In this embodiment, the bone conduction headphones 441 transmit sound vibrations to the user's skull, and then transmit the sound signal directly to the inner ear through the bone, which can provide high-quality voice feedback for blind users without interfering with the sound of the external environment, thus improving the user's safety, comfort and interactive experience.
[0042] like Figure 7 As shown, the wireless communication remote connection module 45 includes a Bluetooth module 451 located inside the eyeglass frame 1.
[0043] In this embodiment, the Bluetooth module 451 adopts the JDY-31 Bluetooth module to realize data transmission with the APP, and communicates with the main control chip 41 through the UART5 transmit line PC12 and receive line PD2.
[0044] like Figure 3 and Figure 7As shown, the real-time feedback module 46 includes a vibration motor 461 located inside the eyeglass frame 1 and a temperature and humidity detection sensor 462 located on the outside of the eyeglass frame 1.
[0045] In this embodiment, the temperature and humidity detection sensor 462 is preferably a DHT11 temperature and humidity sensor, which communicates with the PB5 of the main control chip 41 via a single bus. The detection data is uploaded to the APP, the external environment is analyzed, the user is alerted, and the vibration motor 461 provides real-time information to the user.
[0046] like Figure 5 As shown, a groove 31 is provided on the outer side of the temple 3, and a slider 4411 is provided on the bone conduction earphone 441 that is slidably connected to the groove 31. A limiting member 5 is provided on the slider 4411 for limiting its position.
[0047] In this embodiment, the connection between the slider 4411 and the slide groove 31 allows the slider 4411 to move along the inside of the slide groove 31, thereby adjusting the position of the bone conduction headphones 441 so that the user can move them to a suitable position for use when wearing them. The limiting member 5 can fix the bone conduction headphones 441 after the adjustment is completed.
[0048] like Figures 5 to 6 As shown, a limiting hole 32 communicating with a sliding groove 31 is provided on one side of the temple 3, and multiple sets of limiting holes 32 are provided at equal intervals along its length. The limiting member 5 includes an insert rod 51 that slides through the slider 4411. The insert rod 51 is adapted to the limiting hole 32. A sliding cavity 4412 is provided inside the slider 4411. A collar 52 is provided on the outside of the insert rod 51. The collar 52 is slidably connected inside the sliding cavity 4412. An elastic member 53 is provided on one side of the collar 52. The elastic member 53 is preferably a spring.
[0049] In this embodiment, when adjusting the position of the slider 4411, the insertion rod 51 is pulled outward, causing the insertion rod 51 to move along the inside of the sliding cavity 4412 and deform the elastic element 53. When one end of the insertion rod 51 separates from the limiting hole 32, the slider 4411 can be moved, thereby adjusting the position of the bone conduction earphone 441. After adjusting to the appropriate position, the elastic force of the elastic element 53 causes the collar 52 to drive the insertion rod 51 to re-insert into the limiting hole 32, thus completing the fixation of the slider 4411.
[0050] like Figure 6 As shown, one end of the insertion rod 51 extends to the outside of the slider 4411 and is provided with a pull plate 54.
[0051] In this embodiment, the pull plate 54 makes it easier for the user to pull the plug 51, making the operation more convenient.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
