摘要: 在分析现有锁具机构的基础上,应用机构再生运动链设计法对机构进行还原再生,找出满足拓扑要求与约束要求的非同构运动链,从而实现新锁具的机构创新。首先应用一般化原则将现有玥玛空转锁芯机构转化为与之对应的一般化链;然后运用数综合理论,对原型的机构运动链进行还原,找到所有可能的具有相同构件数和运动副数的一般化运动链图谱;再根据设计要求与约束对运动链进行元件识别,从而得到可行特定化链;最后由可行特定化链具体化为新的锁芯机构方案简图。利用三维软件对新设计的锁芯机构进行三维建模并分析其工作原理,结果表明设计的锁芯机构是合理的,并申请了2项国家发明专利。

Abstract: On the basis of analyses of the existing lock mechanisms, mechanism was restored the regenerative institutions using regeneration movement chain method to identify different kinematic chain mechanisms to meet topology requirements and constraint requirements in order to achieve mechanism innovation of new locks. First, existing Yue Ma idling cylinder body was transformed for corresponding generalized chain by using the principles of generalization; then a prototype kinematic chain was restored using the number synthesis theory in order to find all possible generalized kinematic chain patterns that had the same numbers of components and kinematics; then the movement chain identified the components according to design requirements and constraints , thus a viable specific chain was obtained, and finally the specific chain was transformed into a new organization sketch of lock cylinder. A new 3D model of lock mechanisms was established by using 3D software, and the working principles were analyzed. The results indicate that the lock cylinder mechanisms designed are reasonable, and successfully apply two national invention patents.

Key words: idling lock cylinder, mechanical regeneration movement chain method, general principle, number synthesis, three-dimensional modeling
