Abstract

The invention discloses a deformable wheel of a stair climbing wheelchair, and the deformable wheel includes a driving wheel and a driven wheel, and the driven wheel is connected to the driving wheel and rotates relative to the driving wheel. Each of the driving wheel and the driven wheel includes a hub and three-section of circular arcs surrounding the outer surface of the hub with equal distribution. When the wheelchair climbs stairs, the driven wheel rotates relative to the driving wheel, so that the three-section circular arcs of the driving wheel and the three-section circular arcs of the driven wheel overlap each other. When the wheelchair moves on flat ground, the driven wheel rotates relative to the driving wheel, so that the three-section circular arcs of the driving wheel and the three-section circular arcs of the driven wheel stag each other to form a circle. The deformable wheel is small in size and damages little to the stairs, and is further flexible in operation and can make the wheelchair to operate steadily.

Description

Technical field [0001] The invention relates to the field of stair-climbing wheelchairs, in particular to a deforming wheel of a stair-climbing wheelchair. The deforming wheel is used as a rear wheel of the stair-climbing wheelchair. Background technique [0002] At present, the research and application of wheelchair walking devices mainly include crawler type, wheel group type and track type walking mechanism. The crawler walking mechanism runs smoothly and is suitable for special terrain and environments, but it also has a complex structure, heavy, inflexible movement, large damage to the stairs, and is not suitable for daily life; the wheel group walking mechanism has a fast response speed. , The change of direction is more flexible, and it is widely used in daily wheelchairs, but it also has the shortcomings of unstable movement and slow climbing; the track-type walking mechanism has a simple structure and runs quickly, but it requires a special track and is not suitable for ...
