多功能电动轮椅行走系统设计多功能电动轮椅行走系统设计摘要据调查，我国现在大概有近6000万的残疾人，其中肢残的人数大约有877万，中国还有1.49亿的60岁及以上的老年人，人数排世界的首位，使得无论是老年人还是先天或后天肢体残疾人，他们对于轮椅或者还有除此之外的辅助性步行工具这些的需求真的越来越紧迫。所以这些年我国的轮椅市场就打开了，而轮椅的发展也开始智能化，多功能化，便捷化。总的来说，多功能电动轮椅车它的电源是某一种类型的电池，它的驱动能源装置是使用电动机驱动，电动轮椅车为什么比普通的轮椅车更受人追捧，因为电动轮椅一般基本都有这些优点：操作很简单容易上手，速度平稳安全，噪音小还没有污染，绿色环保等等，我的这篇论文第一点首先是对于国内外的各种轮椅进行分析，然后再记录下它们的优缺点。最后自己设计几种可行的方案，进行一一对比，直至选出来一个最优的方案。关键字：电动轮椅；转向及驱动；机械系统；IBACHELOR'SDEGREETHESISOFCISAUABSTRACTAccordingtothesurvey,thereareabout60milliondisabledpeopleinChinanow.Thedisablednumberabout8million770thousand,Chineseaged60andolderpopulationhasreached149million.21.4%oftheworld'selderlypopulation,thetopoftheworld.Sothatthedemandforwheelchairsandotherauxiliarywalkingtoolsisincreasinglyurgentforboththeelderlyandthedisabled.Ingeneral,thepowerofamulti-functionelectricwheelchairisatypeofbattery,itsdrivingenergydeviceisdrivenbyanelectricmotor,andwhytheelectricwheelchairismorepopularthantheordinarywheelchair,becausetheelectricwheelchairgenerallyhastheseadvantages.Theoperationissimpleandeasytohandle,thespeedisstableandsafe,thenoiseisnotpolluted,greenandsoon.Thefirstpointofmythesisistoanalyzeallkindsofwheelchairsathomeandabroad,andthenrecordtheiradvantagesanddisadvantages.Finally,wedesignseveralfeasibleschemesandcomparethemuntilwechooseanoptimalplan.Keywords:wheelchair;driveandsteeringsystem;mechanicalsysteII目录一、引言...............................................11.1选题的目的及其研究意义...................................................................................11.2国内外多功能电动轮椅的研究现状和发展趋势..........................................11.2.1电动轮椅的现状.........................................................................................11.2.2电动轮椅的发展趋势................................................................................21.2.3应用领域.......................................................................................................21.3主要研究内容、途径及技术路线.....................................................................21.31具体研究内容...............................................................................................21.32主要研究途径和技术路线........................................................................2二、电动轮椅驱动及转向系统的设计及主要参数的计算..........42.1设计内容..................................................................................................................42.2驱动及转向系统设计............................................................................................42.2.1轮椅驱动和转向系统方案分析和选择.................................................42.2.2前轮转向方式中驱动和转向系统设计.................................................62.3主要尺寸..................................................................................................................7三、驱动电机选型.....................................................9四、蓄电池选用................
