摘要
闭锁器是轿车电动门锁的一个重要组成部件,在闭锁器性能检测中测量冲击力和脱滑力时,模拟负载装置要实时地提供给闭锁器拉压双向的50N被动负载。本文针对闭锁器驱动杆做20°左右的往复摆动和挂钩挂轴与锁舌孔联接的要求,提岀一种电动随动模拟负载机构,通过对挂钩和挂钩挂轴的有限元分析确定结构尺寸,设计的电动随动模拟负载装置实现了负载1N—50N,控制精度为满量程的±2%的要求,并可测量闭锁器的最大拖滑力。
The locking device is an important component of a car electric lock,and simulation load device can real-timely provide tension or compression two-way 50N passive load for the locking device in the measurement of impact force and slip force.Aiming at the requirements of locking device driving rod doing about 20° reciprocating swing and the connecting of hook hanging scroll and lock-tongue hole,this paper proposes electric servo simulation load mechanism,which determines the structure and size through finite element analysis of hook and hook hanging scroll and realizes 1N-50N load,the control accuracy reaches ±2% of full range requirements,and it can be used to measure the maximum drag sliding force of the locking device.
