摘 要
上下楼梯是普通日常生活中很平常的一种行为，在那些大量不设电梯的七层以下的住宅楼房居住的居民，尤其是那些老年人和残疾人，上下爬楼在生活上会有诸多的不便。目前无论乡镇还是城市无一不在飞速发展，其中阶梯更是基本的设施之一。如上下汽车、地铁火车有阶梯；登越人行天桥和地下通道需要穿越楼梯；大型商场更是免不了要爬楼下梯。这些在我们看来异常简单的阶梯对那些腿脚不方便的残疾人来说想要通过是很艰难费力的。
基于以上种种因素的考虑，我们设想能不能设计个可以实现上下楼梯的电动轮椅，我们通过在路面电动轮椅的设计基础上进行改装，解决人们在生活中遇到的上下楼梯难题。该电动轮椅的设计，方便了人们的生活。因此，这种电动爬楼轮椅的设计，无论是从实际应用方面还是理论研究方面，都是具有很高价值的。
设计创新之处：
一、 对现有此类产品外观进行改进，造型独特、设计感强；
二、 充分考虑产品的使用目的，设计出人性化，安全舒适，操作简便的产品；
三、 对上下楼梯机的功能进行重新定义，使其功能多元化：上下楼梯、爬越障碍以与物品储存等多功能集合于一身的设计更符合消费者的心理，市场前景无限；
四、 充分组合现国现有比较成熟的生产技术、材料的运用，使产品的成本降低，以求降低残疾人和老年人这些弱势群体生活负担；
五、 充分考虑人机关系，设计出具有可调节功能的产品，造型创新、大胆。
对市场进行了细致的调查，经过设计定位，绘制草图、效果图，绘制出产品外观尺寸图，并设计了效果图展示，完成了对爬楼梯轮椅的设计。

ABSTRACT
Walking up and down stairs is very common in our daily life, in those residents living apartment building which do not set the elevator of the seven layers below, especially those elderly and disabled persons, climbing building up and down in life will have a lot of inconveniences. Currently, both rural and urban areas are all in the rapid among this development tendency the ladder become one of the basic facilities. The ladder help us to fluctuation car ,take the train and underground; climb the passenger foot-bridge and pass through the souterrain; The large shopping centers is inevitable to use the ladder to help climbing stairs.
The exception in our view, a simple ladder legs and feet of those who want to inconvenience people with disabilities is very difficult through the laborious.
Based on the above considerations, we can design a vision can be achieved down the stairs of the electric wheelchairs, electric wheelchairs on the road we passed on the basis of modified design to address the people down stairs in life had design of the electric wheelchair to facilitate people's lives，Thus, the design of electric wheelchairs climbing stairs, either from theoretical or practical application of research, both wit
