摘　　要：针对传统手杖应用的局限性,设计了一款辅助坐立手杖,通过机构重构实现手杖与座椅状态的切换,辅助用户行走与就坐。首先,基于人体自然坐立模型进行了立姿与坐姿尺寸特性测量实验。然后,提出了一种辅助坐立手杖机构,并将尺寸特性测量结果作为该机构尺寸设计的输入参数,完成了该机构功能尺寸设计。最后,运用ADAMS软件进行了运动特性仿真实验。实验结果表明:在手杖状态与座椅状态时,主杆高度、座面与地面的高度差分别为788mm和405mm,符合人体立姿侧向手握距离与坐姿小腿加足高要求。该辅助坐立手杖的设计符合人机工程学,可以在医疗辅助领域推广使用。Aiming at the limitation of traditional walking stick application,an auxiliary sitting and standing walking stick is designed. The switch between walking stick and seat state is realized through mechanism reconstruction to assist users in walking and sitting. Firstly,the size characteristics of standing and sitting posture are measured based on the natural sitting model of human bady. Then,an auxiliary sitting and standing walking stick mechanism is proposed. The dimensiondl characteristics measurement results are used as the input parameters of mechanism’s dimension design,and the functional dimension design of the meechanism is completed. Finally,the simulation experiment of motion characteristics is carried out by using ADAMS software. The experimental results show that the height difference of the main rod and the height difference between the seat surface and the ground are 788mm and 405mm respectively in the walking stick state and the seat state,which meets the requirements of the lateral hand holding distance of the human body in the standing position and the leg heightening in the sitting position. The design of the auxiliary sitting and standing walking stick conforms to ergonomics and can be popularized in the field of medical assistance.
