无障碍出租汽车轮椅升降液压及电控系统设计（本科毕业论文设计）.doc

摘 要

一直以来，行动不便的人或残疾人出行极为不便。随着科学进步和社会文明程度的发展，全球都越来越重视占总人口约7%的各类残障人士的权益保障。在2004年的第38届东京国际车展上，三菱展出了一款无障碍微型厢式车，无障碍车开始被广泛关注。在中国，特别是近两年，很多城市都出现了无障碍公交车，越来越多的地方将人性关怀融入到城市交通。无障碍出租车其中重要的设计环节是无障碍车轮椅升降系统的设计。本课题研究设计了一套无障碍车轮椅升降系统，其中包括：升降平台、控制升降平台在地面与汽车间上升与下降的机构、轮椅锁紧机构、电气控制装置。它适用于不同规格形状的轮椅，实现人坐在轮椅上不动，操作无障碍车轮椅升降系统就能自动上下车，操作简单，动作安全可靠，方便残疾人及老年人乘车出行。

Abstract

All along, persons with disabilities travel very inconvenient.With scientific progress and social development level of civilization ，the rights and interests of security are increasing emphasis of the total population of about 7 percent of all types of disabled people The world .In 2004 the 38th session of the Tokyo International Auto Show, Mitsubishi displayed a barrier-free micro-Van, Barrier-free vehicles began to be widespread concern.In China, in particular the past two years, many cities have a barrier-free buses, more and more places bring care for human traffic into the city.One important barrier-free taxi is part of the design of barrier-free vehicles stair lifts system design.This research designed a wheelchair accessible vehicle movements, including:
Take-off and landing platform, control movements on the ground with the vehicle platform between the rise and fall of the bodies, locking wheelchair, electrical control devices.It applies to different specifications of the shape of a wheelchair,Achieving a wheelchair fixed, Wheelchair accessible vehicle movements operating system will be able to get on and off automatically,Simple, safe and reliable action, To facilitate the disabled and the elderly travel by car.


Keywords: Wheelchair Of Barrier-free vehicles, Take-off and landing system
