Description

Technical Field

[0001] The utility model relates to the technical field of blind canes, in particular to a blind cane with an obstacle encounter prompting function. Background Art

[0002] A cane is a simple instrument for assisting walking, usually a wooden or metal stick. A blind cane, also called a guide cane, is an instrument used by visually impaired people to guide or identify the surrounding environment, which can help them perceive and avoid obstacles to ensure walking safety. In addition to a single rod body, the existing blind canes are generally equipped with high-tech devices such as ultrasonic sensors, infrared sensors, and GPS positioning systems, which can detect obstacles and uneven road surfaces in front of and around the road surface in real time, and broadcast in time through voice, beeping and other methods to remind the blind to pay attention to walking safety. Most of the existing intelligent blind canes are integrated. When the lower rod body is damaged, it needs to be replaced together with the internal intelligent high-tech products, which is inconvenient to use. In view of the above problems, we have developed a blind cane with an obstacle encounter prompting function. Content of the Utility Model
