【摘要】：汽车主动式头枕能够在汽车追尾碰撞时有效地减小头枕和头部的间距,从而实现保护乘车者颈部的作用。针对现有汽车主动式头枕装置的设计缺陷与不足,提出运用TRIZ理论对主动式头枕机构进行创新设计,优化设计了一种基于分割创新原理的非联动式汽车座椅主动式头枕装置,然后通过UG/Motion功能模块对所设计机构进行运动仿真分析。分析结果表明机构运动轨迹符合设计要求,运动过程无干涉发生,从而验证了本机构设计的可行性与正确性。
[Abstract]:The active headrest can effectively reduce the distance between the headrest and the head during the rear-end collision, so as to protect the neck of the passenger. In view of the defects and shortcomings of the existing active headrest device, this paper presents a novel design of the active headrest mechanism based on Triz theory, and optimizes the design of an active headrest device based on the principle of segmentation and innovation. Then the motion simulation analysis of the designed mechanism is carried out through the function module of UG / Motion. The analysis results show that the motion track of the mechanism meets the design requirements, and the movement process has no interference, which verifies the feasibility and correctness of the mechanism design.
