摘要
设计救护车病床平衡系统的机械系统,实现救护车病床在行进中保持水平状态,而无须顾忌地形的变化。利用平衡状态检测装置将病床状态送至单片机,控制步进电机的转动,并设计出独特的机器人关节将滚珠导轨与病床相连接,实现病床三个支脚的升降,从而达到保持水平平衡的目的。救护车病床平衡系统最大可以消除35°倾角、水平误差在±1°以内,反应速度0.3 s。该救护车病床平衡系统成功实现了在行进中保持病床水平状态,避免了因救护车在上下坡过程中倾斜而使患者病情加重的情况。
This is the design of a mechanical systems for use in the balanceable system of ambulance,which can keep the medical service bed at the ambulance level,whatever the terrain is.A level detector will detect the level state of the bed and turn it to a signal.The central processing unit will use this signal to analyse and control the movement of the motor.By this design（which uses the rolling rail as a drive transmission and makes three supports of the bed go up and down）,the bed will keep level.With the use of this design,the balanceable system of ambulance can counteract 35°.The error is controlled within ±1°.And the response time is within 0.3 s.The method of registration can be effective for keeping the bed at the ambulance level,and for reducing the chance of making the patient get hurt on the way to hospital.
