Suspension structure for wheelchair

摘要

The structure has a movable arm (30) connected to driving wheels (31) of a frame (20), and a sliding unit allowing connection of the movable arm to a front cantilever (40) of a wheel chair. The front cantilever cooperates with the movable arm for raising front guide wheels (41), when the wheel chair meets an elevated ground (60). The driving wheels are adhered closely to ground so as to cross an obstacle.
