I可爬梯及越障式手推车可爬梯及越障式手推车机械设计制造及其自动化03班西南大学工程技术学院重庆.北碚.400715摘要日常生活中,当我们去超市购买很多东西时,一般会需要用到超市里提供的手推车。很多超市为了节省空间并不会建造类似于正规医院里的那种绿色通道,所以当我们推着手推车在超市的一楼里买了一些东西后想要到二楼去购物,这时就没有办法把手推车推上二楼去辅助购物了。为了解决这一问题,方便广大市民在超市里购物,同时提升超市对顾客的吸引力。我提出了爬楼梯式手推车的初步设计。论文首先手推车的设计背景、结构及工作流程,然后对其结构进行运动分析,最后谈到了该设计的创新点及应用前景。可爬楼梯式手推车不仅可以帮助市民方便快捷的在在超市、商场购物,同时也可以用在学校的图书馆来辅助的搬运书籍等场合。关键词:可爬楼式;十字轮;平地-爬楼转换、越障;初步设计AbstractIndailylife,whenwegotothesupermarkettobuyalotofthings,weusuallyneedtousethecartprovidedbysupermarket.Inordertosavespace,manysupermarketswillnotbuildaspecialroadsimilartothegreenchannelsinnormalhospitals.Sowhenwepushacarttobuysomethingsfromthegroundfloortothesecondfloorinthesupermaket,itwillbesoII可爬梯及越障式手推车difficultforustopushthecarttothesecondfloortoassistshoppingthatwemaynotbesatisfiedwithourshopping.Inordertosolvethisproblemandfacilitatethemajorityofcitizensinthesupermarketshopping,atthesametimetoincreasesupermarketsonthecustomer'sappeal,Iputforwardapreliminarydesignofthecartwhichcanclimbthestep.Thepaperfirstcartdesignbackground,structureandworkingprocess,andthenthestructuremotionanalysiswascarriedout.Finallytalkedaboutthedesignoftheinnovationpointsandtheapplicationprospect.Cartsabletoclimbstepwisecannotonlymakepeopleconvenientinsupermarketsandshoppingmall,theycanalsobeusedintheschoollibrarytoassistthehandlingbooksandsoon.Keywords:Beingabletoclimbstepwisecart;Thewheel;Theground-climbingupconversion,thebarrier;Preliminarydesign可爬梯及越障式手推车目录摘要1概述...................................................................................................................................-1-1.1设计背景............................................................................................................-1-1.2方案设计说明....................................................................................................-1-1.3性能指标............................................................................................................-3-2设计................................................................................................................................-3-2.1爬楼梯基本结构设计........................................................................................-3-2.2爬楼及平地-爬楼转换......................................................................................-5-2.3平地-爬楼转换机构..........................................................................................-5-2.4越障原理说明....................................................................................................-6-2.5动力设计............................................................................................................-7-2.6主要创新点........................................................................................................-7-2.7小车整体模型图................................................................................................-8-3应用及前景.....................................................
