Child lock mechanism

LIU LIANG / ZHOU XUKUN / ZHANG YONG

The invention relates to the technical field of automobile door locks, and discloses a child lock mechanism which comprises an inner opening arm and a door lock opening mechanism, an inner opening transmission arm is arranged at the bottom of the right end of the front side of the inner opening arm, a child lock arm is arranged on the front side of the inner opening transmission arm, and the door lock opening mechanism is arranged at the bottom of the inner opening arm. A first riveting hole is formed in the bottom of the right end of the front side of the inner opening arm, a second riveting hole is formed in the middle of the right side of the inner opening transmission arm, the inner side of the first riveting hole is fixedly connected to the rear portion of the outer side of a rivet, and a locking claw is arranged on the lower portion of the front side of the door lock opening mechanism. The internal opening transmission arm and the rivet are riveted on the internal opening arm, so that the size of the internal opening arm and the size of the internal opening transmission arm are reduced, the size of the driving mechanism is reduced, the occupied space is greatly reduced, the internal opening transmission arm integrates the functions of a transmission arm and a clutch piece in a traditional mechanism, the number of parts is reduced, and meanwhile a transmission chain is shortened.

本发明涉及汽车门锁技术领域，公开了一种儿童锁机构，包括内开启臂和门锁开启机构，所述内开启臂的前侧右端底部设置有内开传动臂，所述内开传动臂的前侧设置有儿童锁臂，所述内开启臂的底部设置有门锁开启机构，所述内开启臂的前侧右端底部设置有第一铆接孔，所述内开传动臂的右侧中部设置有第二铆接孔，所述第一铆接孔的内侧固定连接在铆钉的外侧后部，所述门锁开启机构的前侧下部设置有止动爪。通过内开传动臂和铆钉铆接在内开启臂上，使内开启臂和内开传动臂体积减小，从而使得驱动机构体积减小，所占据的空间大幅度降低，内开传动臂集合了传统机构中传动臂和离合件的功能减少了零件数量同时缩短了传动链。
