摘要
针对中国老龄化加剧所引发的老人走失及当前智能拐杖发展中存在的问题,设计了一种由照明装置、反光模块和定位装置等构成的螺纹调节式智能助老拐杖。利用老年人的身高、体重等参数对该拐杖进行了机械设计及力学有限元分析。分析结果表明,当拐杖承受的力为2倍老年人体重时,仍具有较高的机械性能,可满足老人的日常出行需求。同时设计了基于北斗导航的智能定位及通信系统,可实时记录老年人的出行状态及位置,保障老年人出行的安全性。与现有智能拐杖相比,该拐杖通过螺纹调节长度,具有更高的稳定性和更长的寿命。
Aiming at the loss of the elderly caused by the increasing aging of China and the problems existing in the current development of smart crutches,this paper designs a threaded adjustable smart crutches composed of lighting devices,reflective modules and positioning devices and so on.It carries out the mechanical design and mechanical finite element analysis of the crutches using the parameters of the elderly height and weight.The analysis results show that when the force of the crutches is twice the weight of the elderly,it still has high mechanical properties and can meet the daily travel needs of the elderly.At the same time,an intelligent positioning and communication system based on Beidou navigation is designed,which can record the travel status and location of the elderly in real time to ensure the safety of the elderly.Compared with the existing smart crutches,the crutches have higher stability and longer lifespan by adjusting the length through threads.
