[0002] In modern society, the ease of travel for visually impaired people has always been a major concern. Traditional guide dogs, with their excellent perception and command comprehension, have provided effective assistance to many visually impaired individuals. However, the training of guide dogs is extremely complex and costly, requiring a significant investment of time and professional resources. With continuous technological advancements, robotic guide dogs have emerged as a new type of guide device, demonstrating broad development potential.

[0003] Currently, the connection device between the guide dog and the user lacks flexibility in design. The operation process is cumbersome when connecting to the guide dog's leash, requiring visually impaired people to spend a lot of time and energy to complete the connection, causing inconvenience in the preparation stage of travel. At the same time, it is difficult to adapt to the various posture changes that occur in the human body during daily walking, climbing stairs, turning and other complex movements, causing users to feel uncomfortable during travel. In addition, in the face of sudden emergencies, the existing connection device often lacks convenient and efficient emergency stop and help mechanisms.

[0004] To address these issues, we have developed a universal human-body connection mechanism for guide dogs. Summary of the Invention

[0005] The purpose of this invention is to provide a universal human connection mechanism for a guide dog.
