介绍了一种抱闸结构式自行车锁的设计方案，包括设计背景、设计要求、结构组成、工作原理等。通过建立抱闸结构式自行车锁的三维实体模型和有限元模型，对该车锁铆钉连接部分和抱闸外壳进行了强度分析，得出了铆钉和抱闸外壳被破坏时能够承受的最大载荷。分析表明，当偷车者强行破坏锁体时，必然会破坏整个抱闸系统，造成自行车不能正常使用，能大大提高自行车的防盗性能。

It introduces a design of brake -structured bicycle lock , including its background , design require-ments, structure, working principle and so on .Through the establishment of the3D model and finite element model of the brake-structured bicycle lock , it conducts analysis on the strength of the bicycle lock's rivet-con-nected part and its brake housing .It shows the peak load of the rivets and the brake housing when being de-stroyed .The numerical results demonstrate that when the lock body is destroyed by thieves, the entire brake sys-tem will inevitably be destroyed at the same time and thus the bicycle will not be working .Therefore , this kind of new lock can greatly improve the theft -proof performance of the bike and have broad market prospects .
