全自动多功能坐态调整轮椅设计
摘要
轮椅是行动不便的老年人与残疾人群日常生活中最重要的工具，他不仅为行动不便的人代步，同时下肢不便的人可以借助轮椅来进行锻炼和恢复，更可以帮助他们与周围的人群进行交流，更好的融入社会。在这种环境下，轮椅的需求变得越来越大。但普通轮椅需要人力推动或使用者本人进行推动来行进、后退，且很难进行转弯等的操作。因使用者长时间坐在轮椅上，又无法通过自己调整坐态，更是加剧了使用者的疲劳程度。对于下肢不便的人来说，轮椅可以达到的高度又是远远不够的，高处的东西自己完全碰不到，又无法通过自己站起来。量身定做或现有的电动轮椅价格又过高，很多人无法接受，使用统一型号的轮椅，舒适度会大大降低。为了帮助这些需要轮椅的人群，我设计了一个结构简单，操作方便，价格低廉，极为舒适的多功能坐态调整的电动轮椅。
通过对国内外电动轮椅的研究成果与国内外市场的调查分析后，确定了本次设计的主要内容与方向。国内成品电动轮椅功能普遍单一。国外成品电动轮椅造价过高，结构反锁，操作复杂，无法满足老年人的需求。本次设计使用简单的结构，通过电推杆与电机来控制轮椅的上升下降与座椅调节，通过六轮行走机构来满足轮椅需要的行走要求。同时简化了轮椅的操作，使用操作杆与简单按键来控制轮椅的所有功能。
本次设计根据老年人与残疾人群的心理与生理需求，运用人性化的设计，整合，修改了现有电动轮椅的外观，结构与功能，使用catia建模，计算分析，设计出了一种新型多功能坐态调整轮椅。可以使老年人或残疾人群在脱离家属，护理人员时完成尽可能多的动作。

Abstract
Wheelchair is the most important tool in the daily life of the elderly and disabled. It is not only for the peoplewith mobility, but also for thosewith lower extremities for exercise and recovery. More can help them communicatewith the surrounding groups, better integration into society. In this environment,wheelchair demand is growing. But ordinarywheelchairs need human push or the user to push forward, backward, and difficult to make turns and so on. Sitting inwheelchairs for a long time, unable to adjust the sitting state, exacerbated the fatigue of the users. For peoplewith lower extremities,wheelchair can reach a height is far from enough, the height of things themselves can not touch, can not stand up through their own. Customized or the existing electricwheelchair prices are too high, many people can not accept, the use of a unified model ofwheelchairs, comfortwill be greatly reduced. To help these people in need ofwheelchairs, I have designed an electricwheelchairwith simple structure, easy operation, low price and extremely comfortable multi-function seat adjustment.
The main contents and direction of the graduation design are determined by the research results of electricwheelchairs at home and abroad and the investigation and analysis of the domestic and foreign markets. Domestic finished electricwheelchair function is generally single. Foreign finished electricwheelchair is too expensive, structural lock, complex operation, unable to meet the needs of the elderly. The design uses simple structure, through electric push rod and motor to control the rise and fall of thewheelchair, through the six-wheelwalking mechanism to meet the needs of thewheelchairwalking requirements. At the same time, it simplifies the operation of thewheelchair, and controls all the functions of thewheelchair by using the lever and the simple button.
According to the psychological and physiological needs of the elderly and the disabled, this design modifies the appearance, structure and function of the existing electricwheelchair by using the humanized design and integration, and uses catia to model, calculate and analyze. A new multi-function seat adjustingwheelchair is designed. The elderly or disabled can perform as many actions as possiblewhen they are separated from their families and nursing staff.
