Abstract

This work presents a design for an automatized multiposition dynamic wheelchair used to transport quadriplegic patients by reconfiguring a manual wheelchair structure. An electric actuator is attached to a four-bar mechanism fixed to each side of a wheelchair's backrest to reach multiposition. The entire device is actuated through a PID controller. An experimental test is carried out in a simplified wheelchair structure. Finally, the structure of the wheelchair is evaluated through the Dynamic analysis and Finite Element Method under the payload computed with the most critical position reached by the mechanism.

摘要

本工作提出了一种自动化多位置动态轮椅的设计，该轮椅通过重新配置手动轮椅结构来运输四肢瘫痪患者。电动执行器连接到固定在轮椅靠背每一侧的四杆机构，以达到多位置。整个装置通过 PID 控制器进行控制。在简化的轮椅结构中进行了实验测试。最后，通过动态分析和有限元方法对轮椅结构进行了评估，计算了机构达到的最危险位置的载荷。
