Description

Technical Field

[0001] This invention relates to the field of electric wheelchair technology, and in particular to a portable, detachable intelligent electric wheelchair. Background Technology

[0002] With continuous advancements in technology, electric wheelchairs have become a key assistive device in modern medical rehabilitation, elderly care, and mobility for people with disabilities. Combining advanced electronic technology and ergonomic design, they provide an efficient and comfortable mobility solution for people with limited mobility. The applications of electric wheelchairs are wide-ranging, primarily covering the following areas: Medical Rehabilitation: In hospitals, clinics, and rehabilitation centers, electric wheelchairs provide convenient mobility for patients and the injured. Home Care: Many elderly and disabled individuals also require wheelchairs for mobility at home. Public Transportation: The convenience and flexibility of electric wheelchairs also make them an ideal choice for public transportation. In public places such as shopping malls, parks, and museums, electric wheelchairs help people with limited mobility move easily and better integrate into society.

[0003] However, despite significant technological advancements in electric wheelchairs, some limitations remain. Most electric wheelchairs currently on the market are single-function, primarily used as wheelchairs. When not in use, these devices often sit idle, resulting in a waste of resources. Furthermore, young people or those with some mobility may desire wheelchairs that can serve other functions beyond transportation, such as acting as a self-balancing scooter or transporting lightweight items.

[0004] Especially for young people, self-balancing scooters have become a popular mode of transportation. Therefore, developing an electric device that combines the functions of a wheelchair and a self-balancing scooter has significant market potential. This would not only provide young people with a stylish and practical travel option but also further promote the innovation and development of electric wheelchair technology. Summary of the Invention
