汽车门锁作为汽车车身的重要附件,其操作性和可靠性关系到汽车的安全和使用性能。针对未来新型汽车对车门开启功能的新要求,以现有汽车侧门锁为研究对象,提出一种可实现电动解锁功能的传动运动链;针对电动开启运动链中连杆传动机构在解锁运动过程中与齿条传动匹配问题,以理论接触点期望轨迹为一条平滑曲线为目标;基于单开链方法,构建具有解耦降次特征的运动学方程组;采用优化-连续法,同时考虑机构运转平稳、尺寸合理等条件,求解出传动机构连杆末端输出点最佳逼近期望轨迹的机构尺寸,为新型汽车门锁传动链研发提供参考。
The automobile door lock is an important accessory for the car body, and its operability and reliability are related to the safety and performance of the car. Aiming at the new requirements of the new car door opening function in the future, the existing car side door lock is taken as the research object, and a transmission kinematic chain that can realize the electric unlocking function is proposed. Aiming at the problem that the connecting rod transmission mechanism in the electric opening movement chain is matched with the rack drive during the unlocking movement, the desired trajectory of the theoretical contact point is a smooth curve as the target. Based on the single open chain method, a kinematic equation system with decoupling and descending characteristics is constructed. The continuous-optimization method is adopted, and considering the conditions of stable operation and reasonable size, the solution output point of the connecting rod meets the optimal size of the desired trajectory, which provides a reference for the development of the new automobile door lock motion chain.
