基于Inventor的助行帮扶轮车的设计

Design of Walking Aid Wheel Car Based on Inventor

利用Autodesk Inventor软件,设计了一款结构新颖、操作简单可靠、实用性强的助行帮扶轮车。在老人独自在居家生活、锻炼等场合中,起到防摔、帮扶、助行、引导及跟随等功能。轮车主要有驱动、整车可变车架、转向及前后操作四大模块构成。通过调整可变姿态机构,可设置攀爬越障(适合进出阳台、卫生间等室内有坡度、小台阶场合)、锻炼漫步跟随、平路座行和原地转弯(转弯半径几乎为“零”)等多种模式。本轮车的研究已获国家专利授权1件、在申请1件,获得全国大学生机械设计竞赛二等奖1项、浙江省大学生机械设计竞赛二等奖1项。

Using Autodesk Inventor software,we gets a wheel car with novel structure,simple and reliable operation and strong practicability.In the elderly alone in the home life,exercise and other occasions,the car plays a fall preven⁃tion,help walking,guidance and follow functions.Wheel car is mainly composed of four modules:drived,vehicle vari⁃able frame,steering and front and rear operation.By adjusting the variable posture mechanism,various working modes can be set,such as climbing obstacle(suitable for entering and leaving balcony,toilet and other indoor places with slope and small steps),exercise walking following,flat road seat and spot turning(turning radius is almost"zero").It can be switched on demand to meet the use needs of the elderly in different scenes at home.The research of this wheel car has obtained 1 national authorized patent,1 patent is in application,and wins 1 second prize of National Col⁃lege Students Mechanical Design Competition and 1 second prize of Zhejiang College Students Mechanical Innova⁃tion Design Competition.
