Abstract

The disabled usually utilize wheelchairs for their daily mobility and locomotion. These motorized vehicles can travel on relatively flat surfaces or tracks without any problems, but moving up and down the stairs is always a challenge for most commercial wheelchairs. In other words, a person with a disability cannot go anywhere inside a multi-story building, shopping store, subway, etc. if they are not built according to accessibility codes. This article proposes two novel designs to facilitate the stair-climbing feature for a motorized wheelchair. One of the design concepts is based on a curved-spoke mechanism with transformation capability from a round wheel to a tri-leg mechanism to facilitate the translation mode as well as the stair-climbing mode of a wheelchair. The next design concept is an enhanced tri-wheel mechanism using a combination of a tri-wheel setup and planetary gears, to provide a unique capability for the climbing mechanism. After analysis and considering the pros and cons of each design concept, the tri-wheel planetary mechanism has been selected for making a scaled-down model and testing the transmission system on the stairs. The scaled-down prototype can successfully move up or down the stairs in the climbing mode and travel on flat or inclined surfaces in the translation mode.

设计爬楼梯轮椅并制作原型
残疾人通常使用轮椅进行日常行动和移动。这些机动车辆可以在相对平坦的路面或轨道上畅行无阻,但对于大多数商用轮椅来说,上下楼梯始终是一项挑战。换句话说,如果多层建筑、购物商店、地铁等没有按照无障碍规范建造,残疾人就无法进入任何地方。本文提出了两种新颖的设计,以方便电动轮椅的爬楼梯功能。其中一个设计概念是基于具有从圆轮到三脚机构转换能力的弧形辐条机构,以方便轮椅的平移模式和爬楼梯模式。下一个设计概念是增强型三轮机构,采用三轮装置和行星齿轮的组合,为爬坡机构提供独特的能力。在分析和考虑了各种设计概念的利弊之后,我们选择了三轮行星机构,并制作了一个缩小模型,在楼梯上测试了传动系统。按比例缩小的原型在攀爬模式下可以成功地上下楼梯,在平移模式下可以在平坦或倾斜的表面上行走。
