首发时间:2017-03-17
摘要:本文在分析人的起立动作过程基础上,设计一种辅助起立障碍病人的新型站立轮椅。首先,设计了站立轮椅的结构,只需一个电动推杆便可实现预期轨迹,比较符合人的起立动作,能让人舒适起立,对防止褥疮也有一定作用;其次,建立并分析该机构的运动学模型,为后面的控制打下基础;最后,对机构进行了简单系统硬件设计和实验验证。

Design of an auxiliary standing wheelchair
Abstract:In this paper, based on the study of human action, a new type of standing wheelchair is designed to assist patients with standing disorder. First of all, the structure of the wheelchair is designed with only a linear actuator and can achieve the desired trajectory. The stand-up mechanism meets people's need by letting a person stand up comfortably and can help patients recover and prevent bedsore. Then, the kinematic model of the mechanism is analyzed, which lays the foundation for the following control part. Finally, the hardware design and experimental verification are carried out.
