Abstract

The invention discloses a deformation walking wheel for a stair climbing wheelchair, comprising a wheel hub component, a wheel disc component and a hydraulic driving component, wherein the wheel hub component and the wheel disc component are connected to form a wheel through the hydraulic driving component. According to the deformation walking wheel, the power provided by hydraulic pressure drives a telescopic rod to extend or retract, so as to realize the sliding deformation of a wheel rim, so that the diameter adjustment of the whole walking wheel is realized. The deformation walking wheel adopts a similar triangular diameter adjusting mode to realize the wheel deformation, so as to realize the leveling of a seat; a wheel disc is self-assembled by modular reconstructed parts; with the combination of the hydraulic driving component and the wheel disc component, the walking wheel converts the step changing movement of the center of the wheel gravity of into gentler movement in the moving process, so that the obstacle crossing is realized.

Description

technical field [0001] The present invention relates to a deformable wheel, more particularly, to a deformed walking wheel suitable for stair-climbing wheelchairs. Background technique [0002] At present, similar products on the market can only realize semi-automatic climbing, and must be helped by others to complete the action and ensure safety, and the mechanism is relatively complicated and expensive. [0003] Wheelchairs are an indispensable means of transportation for the elderly, the infirm and those with lower limb disabilities. However, ordinary wheelchairs do not have the functions of climbing stairs and crossing roadblocks, which greatly limits their scope of use. The research on stair-climbing wheelchairs in the world has a history of nearly 100 years. There are many types of stair-climbing devices and patents at home and abroad. Different stair-climbing devices are suitable for different environments and conditions, and each has its own advantages and disadvanta...
