老年助力车的设计(含CAD图,STEP三维图)(论文说明书11800字,CAD图纸9张,STEP三维图)
摘要:随着科技和社会的发展和进步,各种各样的车辆将会陆续出现在公路上面,与此同时,随着生活水平的提高,针对老年人所开发的车辆也日益普遍,老年助力车也越来越得到广泛的应用,但传统的老年助力车的结构陈旧,笨重且行驶速度慢,制动性能差,所以开发出新式的结构简洁,运行平稳的老年人助力车是当今必须要解决的问题。对这个问题解决的程度如何,反映着一个社会从科技水平到人文关怀等各方面的发达程度。我国对这种现状的重视程度还是不够,即在交通工具上没有安装各种有效的节能设施,这种现状存在着许多不和谐因素,更使群体分化加剧,社会人文关怀程度的下降。
实现绿色驾车无污染化,并实现通过司乘人员,以及经过专门培训的人员对此类老年人助力车的简单辅助操作,即可完成的老年助力车的制动、行驶等等方面的控制,达到环保节能无污染的目的。首先应该从机理的可行性方案上进行深入讨论,通过对动力单元研究着手,然后经过反复细致的可行性,安全性分析以及对整个系统的运动校核,功能分析,而得到并形成系统的整体的结构,并且针对本系统的特点,来选择最适合的系统方案。
因此,本文首先就方案的选择进行了研究,通过设计者掌握的专业基础知识,互联网上的相关资料以及国内外已有的设计种类的现状,经过详细的方案调查,为本次毕业设计设计出了一套环保节能的老年助力车。

Abstract:With the aging of the population problem is becoming more and more serious, the elderly and disabled travel, there is a problem in any country. How to solve this problem, which reflectsthe developed degree of a society from the level of science and technology to the humanistic care and other aspects of the. Our attention to this situation or not, that is no easy installation in vehicles off disabilities on facilities, this situation there are many inharmonious factors, more make the populationdifferentiation, a decline in social humanistic concern degree. The arrangement oflifting system for disabled people in the car, can improve the above situation.
The disabled to pedal accessibility, and realize the company by personnel, andtrained personnel to operate this set of machinery, control to complete the disabledspecial automobile seat lifting system, to enable the disabled smoothly on the trainobjective. Should first in-depth discussion from the feasibility scheme of the mechanism, through the hands of the power unit, and then after repeated and carefulfeasibility, safety analysis and correction of motion,.
the system function analysis, and get and the formation of system's overall structure, and according to the characteristics of the system, to select the most suitable system scheme the.
