Barrier-free wheelchair, control system and control method
By adding a drive frame and a push mechanism to the wheelchair, combined with sensors to automatically identify obstacles, the wheelchair can move forward and backward up and down stairs and on flat ground, solving the problems of weak obstacle-crossing ability and inflexible center of gravity adjustment of existing wheelchairs, and improving the freedom of movement and safety.

AI Technical Summary
Existing wheelchairs suffer from weak obstacle-crossing capabilities in various environments, lack tracked structures, and are particularly prone to problems with symmetrical layouts. These issues include limited obstacle-crossing directional capabilities, lack of tracked lateral adjustment, and an inability to achieve forward or backward obstacle crossing. Furthermore, the seat's center of gravity adjustment is inflexible, making it difficult for users to navigate in complex environments.
Design an accessible wheelchair by adding a first drive frame and a second drive frame that are hinged to the frame. The first drive mechanism and the second drive mechanism are used to tilt and lift the tracks. Combined with the hinged structure of the push mechanism and the seat frame, the tracks can slide forward and backward and the seat can be adjusted horizontally. Equipped with a multi-sensor perception layer to automatically identify obstacles, the control system automatically matches the working mode to enable forward and backward movement up and down stairs and on flat ground.
It enables wheelchairs to cross obstacles in both directions, improving freedom of movement and safety, adapting to complex environments, significantly enhancing seat stability and comfort, and is easy to operate, making it suitable for the elderly and people with disabilities.
