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 protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A pair of guide glasses includes a frame 1 and an intelligent guide system 2. Lenses 3 are provided on both sides of the bottom of the frame 1. Temple structures 4 are provided on both sides of the frame 1. A battery 5 is provided on the inner side of the top of the frame 1. A main board 6 is provided on the inner side of the top of the frame 1. A processing chip 7 and a positioning sensor 8 are electrically connected to the top of the main board 6. A visual acquisition camera 9 and a distance sensor 10 are embedded in the front of the frame 1. An intelligent voice player 11 is provided on the inner side of the temple structure 4.

[0029] The intelligent guidance system 2 includes a control terminal 201, a PP-YOL0v2 analysis module 202, a TOF laser ranging module 203, a voice module 204, an NB-IoT dual-mode positioning module 205, a cloud platform 206, and a mobile APP terminal 207. The output of the PP-YOL0v2 analysis module 202 is unidirectionally electrically connected to the receiver of the control terminal 201; the output of the TOF laser ranging module 203 is unidirectionally electrically connected to the receiver of the control terminal 201; the receiver of the voice module 204 is unidirectionally electrically connected to the output of the control terminal 201; and the receiver of the NB-IoT dual-mode positioning module 205 is unidirectionally electrically connected to the output of the control terminal 201. The output end of the cloud platform 206 is unidirectionally electrically connected to the output end of the NB-1oT dual-mode positioning module 205. The receiving end of the mobile APP terminal 207 is unidirectionally electrically connected to the output end of the cloud platform 206. The receiving end of the intelligent guide system 2 is unidirectionally electrically connected to the power supply module 208, which is a battery 5. The NB-1oT dual-mode positioning module 205 is a positioning sensor 8. The voice module 204 is an intelligent voice player 11. The TOF laser ranging module 203 is a ranging sensor 10. The PP-Y0L0v2 analysis module 202 is a visual acquisition camera 9. The control terminal 201 is a processing chip 7.

[0030] In this embodiment: By setting up an intelligent guidance system 2 and a temple structure 4, the visual acquisition camera 9 of the PP-YOLOv2 analysis module 202 within the intelligent guidance system 2 captures surrounding images in real time. Then, the PP-YOLOv2 analysis module 202 uses algorithms for in-depth analysis to accurately identify pedestrians, vehicles, obstacles, traffic signs, etc., converting visual information into data and transmitting it to the processing chip 7. Simultaneously, the ranging sensor 10 of the TOF laser ranging module 203 emits laser pulses to measure obstacle distance and also transmits data to the processing chip 7. The processing chip 7 then uses the NB-IoT dual-mode positioning mode of the positioning sensor 8 to perform the analysis. The position feedback of block 205 determines the orientation, and then issues instructions to the intelligent voice player 11 of voice module 204. It then broadcasts the environment, obstacle distance and navigation to the visually impaired person in clear voice to help them avoid danger. In addition, the visually impaired person can personalize the settings as needed on the mobile APP terminal 207, and family members can remotely monitor and assist them in a timely manner through the cloud platform 206. At the same time, the temple structure 4 and the frame 1 work together in an ergonomic way to secure the glasses and prevent them from shifting or slipping. The intelligent voice player 11 is ergonomically installed on the inside to allow the sound to be better transmitted to the ear without extra weight. The voice is clear and prevents the visually impaired person from missing information.

[0031] Specifically, such as Figure 3 As shown, the temple structure 4 includes a fixed frame 401 fixedly connected to both sides of the frame 1, and a torsion rod 402 is rotatably connected inside the fixed frame 401.

[0032] Specifically, such as Figure 3 As shown, a temple 403 is fixedly connected to the rear side of the torsion bar 402. The temple 403 is located on the rear side of the frame 1, and the inner side of the temple 403 is fixedly connected to the smart voice player 11.

[0033] Specifically, such as Figure 3 As shown, a protective sleeve 404 is fitted onto the rear side of the temple 403, and the protective sleeve 404 is made of rubber material.

[0034] In this embodiment: by setting the temple structure 4, the temple 403 and the frame 1 cooperate ergonomically, and the torsion bar 402 inside the fixed frame 401 can rotate flexibly to adapt to different head shapes and head movements, ensuring that the glasses are worn securely and effectively preventing displacement and slippage. The inner side is carefully equipped with a smart voice player 11, which allows clear voice to enter the ear without any obstruction, and does not add extra weight to the visually impaired person, minimizing the risk of missing key information. The rubber protective sleeve 404 attached to the back of the temple 403 not only improves the grip but also acts as a buffer in case of accidental drop, providing all-round protection and continuous escort for the visually impaired person's travel.

[0035] Specifically, such as Figure 2 As shown, a charging connector 12 is embedded in the top left side of the frame 1. The charging connector 12 is electrically connected to the battery 5. An on / off button 13 is provided on the top right side of the frame 1. The on / off button 13 is electrically connected to the battery 5, the motherboard 6, the voice player, the visual acquisition camera 9, and the distance sensor 10.

[0036] Specifically, such as Figure 2 As shown, a cover 14 is snapped onto the top of the frame 1, and the cover 14 is located at the bottom of the battery 5 and the mainboard 6.

[0037] In this embodiment: By setting a charging connector 12 and an on / off button 13, the charging connector 12 is electrically connected to the storage battery 5, making it convenient for visually impaired users to charge the storage battery 5 at any time by connecting the charging connector 12 with a compatible charger. The on / off button 13 is electrically connected to the storage battery 5, the motherboard 6, the voice player, the visual acquisition camera 9, and the ranging sensor 10, respectively, acting as a control hub. Visually impaired users can easily press a button to turn the entire device on or off with one click, and can also quickly restart the device when it malfunctions. Simple operation enables flexible control of each key component, making the usage process more convenient.

[0038] Specifically, such as Figure 3 As shown, a protective net 15 is attached to the inner side of the temple 403, and the protective net 15 is located on the outside of the voice player.

[0039] Specifically, such as Figure 4 As shown, a nose bridge reinforcement bracket 16 is attached to the inner side of the lens 3, and the bottom of the nose bridge reinforcement bracket 16 is arc-shaped.

[0040] In this embodiment: the use comfort and stability are improved by setting a protective net 15 and a nose bridge reinforcement 16. The protective net 15 is fastened to the inside of the temple 403 and located on the outside of the voice player. The fine mesh effectively blocks dust, droplets and other tiny particles, preventing them from entering the voice player and causing damage, extending the service life of the device, and maintaining the clear sound quality of voice playback. The nose bridge reinforcement 16 is fastened to the inside of the lens 3. The bottom arc shape precisely fits the physiological curve of the nose bridge, evenly distributing the overall weight, reducing pressure on the nose bridge, and preventing pressure marks from forming after long-term wear. Even if the visually impaired person moves frequently, it can provide stable support, ensuring the comfort and stability of wearing.

[0041] Working Principle: During the daily travel of visually impaired individuals using guide glasses, the intelligent guide system 2 is activated. Its PP-Y0L0v2 analysis module 202's visual acquisition camera 9 captures surrounding images in real time. Then, using deep analysis algorithms, it accurately identifies pedestrians, vehicles, obstacles, traffic signs, etc., converting visual information into data that is transmitted to the processing chip 7. Simultaneously, the TOF laser ranging module 203's ranging sensor 10 emits laser pulses to measure the distance to obstacles, also transmitting data to the processing chip 7. The processing chip 7 determines the orientation based on the position feedback from the NB-1oT dual-mode positioning module 205, and then issues commands to the intelligent voice player 11 of the voice module 204. It immediately broadcasts the environmental conditions, obstacle distances, and navigation guidance to the visually impaired individual in clear voice, helping them avoid danger in a timely manner. The visually impaired individual can also personalize settings as needed on the mobile APP terminal 207, and family members can remotely access information via the cloud platform 206. The system monitors the dynamics and provides timely assistance. The temple 403 structure is equally crucial. The temple 403 and frame 1 work together ergonomically. The torsion bar 402 inside the fixed frame 401 rotates flexibly to adapt to different head shapes and movements, ensuring a stable fit and preventing the glasses from shifting or slipping. The smart voice player 11 installed inside allows clear voice input to the ear without additional weight. The protective net 15 blocks dust and droplets, protecting the player and maintaining sound quality. The rubber protective cover 404 on the back improves the grip and cushions the impact of drops. The charging connector 12 on the top left of the frame 1 facilitates connecting a charger to charge the battery 5. The on / off button 13 on the right serves as the control hub, allowing one-button control of the device's power on / off and restart, and easy operation of key components. The nose bridge reinforcement 16 inside the lens 3 has an arc-shaped bottom that conforms to the physiological curve of the nose bridge, evenly distributing weight, reducing pressure on the nose bridge, and ensuring comfort and stability during long-term wear. It provides comprehensive protection for the travel of visually impaired individuals.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
