摘　　要：针对高端汽车门锁电动吸合及开启优先功能需求,提出了凸轮摆杆柔顺连杆组合机构,构造了双凸轮单摆杆和含弹簧构件四杆机构的组合机构,结合限位块、接触状态、凸轮间歇运动、型面突变等构件特征,可实现柔顺自适应滚滑、刚性拨动、避让释放3种运动模式及各模式间切换;嵌入锁内棘轮棘爪锁紧机构,将组合机构转化为电动吸合与开启支链;对应汽车门锁电动吸合、手/电动开启及复位、吸合复位3种工况,以相应驱动方式和运动边界条件,研究分析了吸合运动与锁内现有支链的运动兼容功能、开启优先功能、吸合卡止情况半锁开启功能。将机构及驱动嵌入车门锁进行仿真,研究了全工况开启凸轮与摆杆、摆杆与棘轮、棘轮与棘爪的接触力;机构仿真实现各功能动作的时间与车门锁设计要求匹配,其由半锁到全锁的吸合过程时间为420.97 ms,复位时间为29.03 ms,手动开启时间为622 ms。Aiming at the demand of electric cinch and release priority function of high-end vehicle door latches,a cam swing linkage and spring linkage combined mechanism is proposed,and a combined mechanism of double cam single swing linkage and spring four bar mechanism is constructed.Combined with the characteristics of limiting blocks,contact states,cam intermittent movement,profile abrupt change and other components,it can realize three motion modes of flexible and adaptive rolling,rigid pushing,avoiding and releasing,and switch among them.Embedded into the ratchet and pawl locking mechanism,the combined mechanism is transformed into electric cinch and release branches,corresponding to the three working conditions of the vehicle door latch:electric cinch,manual or power release and reset,and cinch branch reset.Based on the corresponding driving modes and motion boundary conditions,the compatible function of the cinch motion and the existing branches in the latch,the release priority function,and the half-lock release function in the case of the cinch pinch are studied and analyzed.The mechanism and the drive are embedded in the door latch for simulation,and the contact force between the release cam and the swing linkage,the swing linkage and the ratchet,and the ratchet and the paw are studied in all working conditions.The time of the mechanism to realize each function matches the design requirements of the vehicle door latch,the time of the electric cinch process is 420.97 ms,the reset time is 29.03 ms,and the manual release time is 622 ms.
