Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and more particularly to visual aid navigation glasses for the blind. Background Technology

[0002] With the development of society, people are paying more and more attention to caring for and helping vulnerable groups. As a part of this group, the safety of blind people in their daily travel has always been a major concern.

[0003] Traditional methods of assisting the blind in their travel primarily rely on tools such as guide canes. However, guide canes can only perceive road conditions within a limited range by touching the ground or obstacles at the tip. Their detection range and accuracy are quite limited, making it difficult for blind people to fully understand the distribution of obstacles in their surroundings in advance. For example, obstacles at heights or small obstacles at a distance are often difficult to detect effectively. This leaves blind people with a high risk of collisions while walking, seriously affecting their travel safety and independence.

[0004] Meanwhile, the rapid advancement of modern technology has provided new opportunities and directions for solving the travel difficulties of blind people. The continuous maturation and widespread application of camera and audio technologies have made it possible to develop a more intelligent and efficient assistive device for blind people. By combining a camera with a speaker, the camera can capture real-time images of the blind person's surroundings. With the help of advanced image processing algorithms and intelligent recognition technology, various types of obstacles, including but not limited to pedestrians, vehicles, buildings, and street facilities, can be detected quickly and accurately.

[0005] The audio system, as a key component for information output, converts obstacle information detected by the camera into audio signals. It promptly informs blind people of the location, distance, and general outline of obstacles in a clear and easy-to-understand manner, enabling them to react in advance while walking and avoid obstacles more safely and confidently. This greatly improves the safety and convenience of blind people's travel, thus filling the gaps in traditional blind travel aids in terms of environmental perception and information feedback, and bringing new hope and improvement to the lives of blind people.

[0006] In conclusion, developing a visual aid navigation glasses for the blind based on the coordinated operation of a camera and a speaker has significant practical implications and is an urgent social need, and is expected to significantly improve the quality of life and travel safety of blind people. Utility Model Content

[0007] This invention addresses the shortcomings of existing technologies by utilizing the coordinated operation of a camera and a speaker to assist blind individuals in their travels. The camera captures various obstacles, including pedestrians, vehicles, buildings, and street infrastructure.

Example

[0039] Please see Figure 1-5 Visual aid navigation glasses for the blind, including:

[0040] The main frame of the glasses (1) forms the main frame of the glasses and is used to mount the lenses.

[0041] Eyeglass temple 2, connected to the eyeglass body 1, is used to wear on the ears to support the eyeglass body 1;

[0042] Speaker 3, mounted on the temple of the glasses 2, is used to play audio to remind blind people to avoid obstacles;

[0043] Camera 4 is electrically connected to speaker 3 to enable data transmission and collaborative operation, and is used to capture environmental information and transmit it to speaker 3 for audio prompts.

[0044] The visual aid navigation glasses for the blind in this application are mainly composed of the glasses body 1, the temples 2, the slots 201, the speaker 3, the camera 4, and the buckles 5. The following is a detailed description of the structure and working principle.

[0045] I. Overall Structure of Eyeglasses

[0046] The eyeglasses body 1 and the eyeglass temples 2 constitute the basic frame of the eyeglasses. The eyeglasses body 1 is used to mount the lenses, and the eyeglass temples 2 are used to wear the eyeglasses over the ears, thereby supporting the eyeglasses body 1.

[0047] A speaker 3 is mounted on the temple of the glasses 2 to play audio to alert blind people to avoid obstacles. Several slots 201 are provided on the side of the temple 2, and several clips 5 are provided on the side of the speaker 3 facing the temple 2. During installation, the clips 5 are aligned with the slots 201 and inserted. The clips 5 are elastic; during insertion into the slots 201, they are compressed by the inner wall of the slots 201 and undergo a certain degree of deformation. Once fully inserted into the slots 201, the clips 5 return to their original shape, tightly pressing against the inner wall of the slots 201, achieving a preliminary and stable connection.

[0048] Meanwhile, a first magnetic layer 202 is provided on the inner end face of the card slot 201, and a second magnetic layer 501 is provided on the insertion surface of the buckle 5. When the buckle 5 is inserted into the card slot 201, the first magnetic layer 202 and the second magnetic layer 501 attract each other and generate a magnetic attraction state, further ensuring the stable installation of the speaker 3 on the temple of the glasses 2.

[0049] The clip 5 is connected to the speaker 3 via a stabilizer 6. The end of the stabilizer 6 facing the temple 2 is curved. After installation, this curve can fit tightly against the outer wall of the temple 2, ensuring the tightness and stability of the connection between the clip 5 and the temple 2, thereby ensuring the overall stability of the speaker 3 installation.

[0050] Camera 4 settings

[0051] Camera 4 is positioned on the side of the glasses body 1 and is electrically connected to speaker 3 to enable data transmission and collaborative operation. During connection, a flexible circuit board or miniature ribbon cable is used to establish the electrical connection between camera 4 and speaker 3. These connection lines can be cleverly concealed inside the glasses frame, without affecting the appearance of the glasses or wearing comfort.

[0052] Charging port 301 and protective cover 302

[0053] The speaker 3 has a charging port 301 at its rear for powering the internal lithium battery. A protective cover 302 is located around the charging port 301, which can be easily inserted into the port. To charge, simply open the cover 302 and insert the charging cable into the port 301. After charging, close the cover 302 to prevent dust and moisture from entering the port, ensuring its cleanliness and proper functioning.

[0054] The speaker 3 contains a lithium battery, which is connected to the charging port 301 at the rear of the speaker 3 via a built-in charging circuit. The charging circuit has charging protection functions, such as overcharge protection, over-discharge protection, and short-circuit protection. When an external power source is connected through the charging port 301, the charging circuit regulates and controls the input current and voltage to ensure the lithium battery charges safely and stably. Once the lithium battery is fully charged, the charging circuit automatically cuts off the charging current to prevent overcharging and damage.

[0055] A protective sleeve 7 is fitted over the temples 2, and the protective sleeve 7 is made of rubber. The rubber material has good flexibility and friction, which can protect the temples 2 from scratches and collisions during daily use, and can also increase the friction between the temples 2 and the ears and scalp, preventing the glasses from slipping off easily during wear.

[0056] II. Working Principle

[0057] When a blind person wears these visual aid navigation glasses, camera 4 will capture images of the environment around the blind person in real time. Camera 4 can capture environmental information within a certain range, including pedestrians, vehicles, buildings, street facilities, and other possible obstacles.

[0058] The image data captured by camera 4 is transmitted to speaker 3 via an electrical connection. The processing unit inside speaker 3 can be a microprocessor integrated on a circuit board or other dedicated processing chip to process the image data. Through built-in advanced image processing algorithms and intelligent recognition technology, the processing unit can quickly and accurately identify obstacles in the image and calculate key information such as the location, distance, and approximate outline of the obstacles relative to the blind person.

[0059] The processing unit then converts this obstacle information into audio signals. For example, when an obstacle is detected directly in front, an audio signal with a specific frequency or rhythm is generated; when the obstacle is closer, the frequency of the audio signal may increase or the volume may be increased to remind the blind person to pay more attention.

[0060] Speaker 3 plays the converted audio signal, allowing blind people to understand the obstacles in their surroundings through the audio cues they hear and take appropriate evasive actions in advance, thus making their journey safer.

[0061] The lithium battery inside speaker 3 provides power for the entire device. The lithium battery stores electrical energy and outputs a stable current while the device is operating. When the blind person activates the navigation function on their glasses, the lithium battery powers camera 4, the processing unit inside speaker 3, and other related electronic components, ensuring their proper functioning.

[0062] When the lithium battery is low, it is charged through the charging port 301 at the rear of the speaker 3. An external power source is connected to the charging port 301 via a charging cable, and current flows through the built-in charging circuit to charge the lithium battery. During charging, the charging circuit monitors the battery's charging status in real time to ensure a safe and efficient charging process. Once the lithium battery is fully charged, the charging circuit automatically stops charging to protect the battery's lifespan and the device's safety.

[0063] Through the above specific implementation methods and working principles, visual aid navigation glasses for the blind can effectively help blind people avoid obstacles while walking, improving the safety and convenience of travel.

[0064] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
