Technical Field

[0001] The utility model relates to the technical field of blind-guiding devices, in particular to a blind-aiding cap. Background Art

[0002] The size of the blind population in my country is growing, but the various players in the market pay relatively little attention to mobility aids for the blind, and the types and quantities of mobility aids are relatively small.

[0003] The existing technology of blind walking aids is still in its early stages, and is still mainly based on the use of canes and guide dogs. The disadvantage of canes is that they cannot warn of suspended objects. Even if there are objects on the ground, they can only be detected when the canes touch the objects. If they do not touch them, accidents may occur. In addition, in crowded places, the canes may touch passers-by and cause discomfort. Guide dogs take a long time to train, have high breeding costs, and are in short supply, so they can only provide services to a small number of people. Utility Model Content

[0026] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. During actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0028] like Figure 1 As shown, the utility model provides a blindness-aiding cap, comprising a cap body 10, a power source 20, an ultrasonic sensor 30 and a warning light 40. The cap body 10 is the basic structure of the blindness-aiding cap, providing protection and support for the user's head. It may be made of a light and breathable material to ensure comfortable wearing.

[0029] The power source 20 is disposed on the cap body 10. The blind-aiding cap requires the power source 20 to drive the ultrasonic sensor 30 and the warning light 40. The power source 20 may be a built-in rechargeable battery or a replaceable battery. Ensure that the power source 20 can provide sufficient long-term power consumption to support long-term use.

[0030] The ultrasonic sensor 30 is arranged on the front side of the cap body 10 and faces forward, and the ultrasonic sensor 30 is electrically connected to the power supply 20. The ultrasonic sensor 30 is installed at the front of the blind aid cap and is used to measure the distance of the obstacle in front in real time. It can send ultrasonic waves and receive the reflected signal, and determine the distance of the object by calculating the reflection time. Such a sensor can help the blind perceive the obstacles in front and provide timely warnings.

[0031] Warning light 40 The warning light 40 is arranged on the front side of the cap body 10, and the warning light 40 is connected to the ultrasonic sensor 30 signal, and the warning light 40 is electrically connected to the power supply 20. When the distance to the obstacle or pedestrian is within 1 meter, the warning light 40 will flash continuously, visually reminding pedestrians that there is a blind person nearby and they should pay attention to avoid it. The warning light 40 is usually installed on the top or front of the blind aid cap to improve the visibility of the blind. It can attract the attention of people around by flashing or emitting bright light, reminding them to pay attention to the presence of the blind and take necessary actions to avoid it.

[0032] In a specific embodiment of the utility model, a speaker and / or a buzzer are provided on the cap body 10. The speaker can play a pre-recorded prompt voice to remind people around to pay attention to the actions of the blind person and keep a safe distance. This voice prompt can be a clear and bright voice that is easy to hear and understand. The buzzer can generate a high-frequency audio signal to attract people's attention. The sound of the buzzer is usually more direct and urgent than the voice prompt of the speaker, and is suitable for situations where attention needs to be attracted quickly. Combining the speaker and the buzzer, a variety of prompt methods can be created. For example, voice prompts are used at a longer distance, and buzzers are used at a closer distance to enhance the warning effect.

[0033] like Figure 2 As shown in the figure, the ultrasonic ranging sensor is used to measure the distance in real time. When entering the range of 3 meters, it will prompt: Pedestrians, please pay attention, a blind person is passing by, please keep a safe distance. At a longer distance, the system warns pedestrians around that there is a blind person walking and recommends keeping a safe distance. This helps prevent accidental collisions and provides early warning.

[0034] When the blind person approaches, the system will remind the pedestrians in front through a prompt, so that they can actively avoid the blind person. This helps create a safer walking environment and reduce potential collision risks.

[0035] When entering the 1-meter range, the system will prompt: "Please pay attention, there is a blind person here, please make way." When the distance is shortened to less than 1 meter, the system will issue a more urgent warning to everyone around, emphasizing that there is a blind person nearby, prompting more rapid avoidance behavior. This helps ensure safety even at very close distances.

[0036] These prompts can help the blind to effectively avoid obstacles and pedestrians, seek maximum safety, and achieve reasonable and safe obstacle avoidance effects.

[0037] like Figure 1 As shown, the cap body 10 is provided with an alarm button 50. Figure 3As shown, when the alarm button 50 is pressed, an alarm will be issued to pedestrians or 110 or 120. The alarm button 50 allows the blind person to immediately trigger an alarm when encountering an emergency, whether it is due to an accident, physical discomfort or other emergency situations. The alarm button 50 can be designed to have multiple functions, such as triggering an audible alarm, sending an emergency help message to a preset contact, activating a surrounding monitoring system, etc. In order to avoid accidental touches, the alarm button 50 should be designed to require a certain degree of force or continuous pressing to be triggered. After the alarm button 50 is triggered, the alarm system of the blind-assisting hat should respond immediately and send an alarm message to the people around to seek help or attract attention.

[0038] like Figure 1 As shown, the cap body 10 is provided with a knob 60 for adjusting the volume of the speaker and / or buzzer. Figure 4 As shown, the buzzer sound can be turned on or off at will (the sound will emit different decibel volumes depending on the distance of the obstacle). Knob 60 can be used to adjust the volume of the speaker and / or buzzer, allowing the user to adjust it according to factors such as the surrounding noise level and personal hearing level. Knob 60 can be designed to be more than just a volume adjustment, but also a switch for the speaker and / or buzzer. In this way, the user can choose to turn off the warning sound in a specific situation to avoid interruption or reduce the urgency of the alarm. This design provides users with greater flexibility, allowing them to adjust the volume according to their specific needs rather than just accepting a preset fixed volume level. The position of knob 60 should be designed to be easy to reach and adjust, and can be easily used even in different weather conditions or when wearing gloves.

[0039] like Figure 1 As shown, the alarm button 50 and the knob 60 are placed on both sides of the cap body 10 near the human arm. Placing the button and the knob 60 on both sides near the human arm allows the user to easily reach and operate without excessively turning the head or looking for a specific position. Due to the natural movement direction of the human arm, the user can more easily find and press the alarm button 50 without excessive body movements. This helps to trigger the alarm more quickly in an emergency. Placing the alarm button 50 and the knob 60 on both sides helps to avoid confusion, ensuring that the user can accurately select and trigger the required function to avoid misoperation. Distributing these control devices on both sides can better balance the design of the cap body 10 to improve the comfort of wearing and reduce the single side load on the user's head. The user can easily find the position of the button and the knob 60 by touch without over-relying on vision. This is very important for blind users. Placing the button and the knob 60 on both sides also helps to reduce interference with each other, ensuring that the user can independently select the function to be executed.

[0040] like Figure 1As shown, the cap body 10 includes a brim 11 extending forward, and an ultrasonic sensor 30 is arranged at the front end of the brim 11. The ultrasonic sensor 30 can detect obstacles in front and measure the distance between the obstacles and the brim 11. Such a design enables the blind to detect obstacles in front in time and take corresponding actions. By detecting obstacles in advance, the system can trigger an alarm to remind the user that there are obstacles in front to avoid collisions and possible injuries. Embedding the ultrasonic sensor 30 at the front end of the brim 11 can keep the appearance of the cap body 10 simple and streamlined, and avoid adding too many protruding parts.

[0041] like Figure 1 As shown, a road sensor 70 is provided at the lower side of the front end of the brim 11, and the road sensor 70 is tilted downward from the back to the front. The road sensor 70 can sense the condition of the ground, including but not limited to flatness, bumps, slopes, etc. This helps the blind to understand the conditions of the walking road ahead and adapt to the footsteps in advance. By detecting the bumps and slopes of the road surface, the blind-assisting hat can provide corresponding feedback to help users choose a flatter and more comfortable path and reduce walking discomfort. When uneven changes or protrusions on the ground are detected, the blind-assisting hat can sound an alarm to remind users of possible tripping hazards and help them take avoidance measures. The data of the road sensor 70 can be integrated with other navigation systems to provide more accurate walking suggestions and help users cross different terrains safely and quickly. Together with the ultrasonic sensor 30, the road sensor 70 can provide more comprehensive environmental perception. This helps the blind-assisting hat better adapt to complex walking environments and improve the user's sense of security.

[0042] like Figure 1 As shown, the cap body 10 is provided with a reflective strip 12. The reflective strip 12 can reflect light in low light conditions, making the blind-aiding cap more easily noticed by other pedestrians, drivers, etc. This helps to improve the visibility of the blind when walking at night and reduce the risk of traffic accidents. The use of the reflective strip 12 can make the blind-aiding cap easier to identify in the crowd, reduce confusion with other pedestrians, and help socializing and avoid collisions.

[0043] like Figure 1 As shown, the power source 20 is detachably arranged above the cap body 10. Designing the power source 20 to be detachable allows the user to easily replace the battery or rechargeable battery without professional technical support. This improves the maintainability of the power source 20. If the power source 20 is rechargeable, the user can easily remove the power source 20 module and connect it to the charger without removing the entire blind-aiding cap. Placing the power source 20 above the cap body 10 helps to distribute the weight, making the blind-aiding cap more comfortable and reducing the burden on the user's head.

[0044] In a specific embodiment of the utility model, a position warning light is provided on the rear side of the cap body 10. The provision of the position warning light makes it easier for other pedestrians, vehicles, etc. to notice the presence of the blind person, especially at night or in low light conditions. The position of the position warning light can be used to indicate the walking direction of the blind person, which is very helpful for others to understand the behavior and intention of the blind person.

[0045] In summary, the utility model proposes a blind-assisting cap, in which a forward ultrasonic sensor 30 is added to the cap body 10 for real-time distance measurement, which can measure the distance ahead in real time to detect obstacles. This can provide timely warnings and obstacle avoidance guidance to help the blind avoid collisions and accidents. When there is an obstacle ahead, an alarm can be given, and a warning light 40 is also provided. The warning light 40 can flash while giving an alarm, especially at night or in low light conditions, to attract the attention of others and let them know that the blind are approaching and need to be avoided. This can improve the visibility of the blind in traffic and in the crowd.
