Door lock driving output shaft, door lock driving device and intelligent door lock
The invention discloses a door lock driving output shaft, a door lock driving device and an intelligent door lock. A door lock driving device comprises an execution element and an output assembly. The output assembly comprises an output gear and an output shaft; the output gear comprises a bushing and a gear ring, and a friction part is arranged between the bushing and the gear ring; the output shaft is arranged in the lining and provided with a connecting cavity used for being connected with the lock cylinder shaft in a matched mode, and an elastic part with radial elasticity is arranged in the connecting cavity. According to the door lock driving device, when a door lock is installed and debugged, the output shaft and the lock cylinder shaft are easy to be concentric or approximately concentric; when the output shaft and the lock cylinder shaft are staggered, the two shafts can be stably connected through the elastic force of the elastic part, and the torque transmission efficiency is high. Even if overlarge torque output exists and is larger than a friction force critical value, relative sliding is generated between the lining and the gear ring, and the problems of tooth hitting, even breakage and jamming are avoided.
本发明公开了一种门锁驱动输出轴、门锁驱动装置及智能门锁。一种门锁驱动装置，其包括执行元件和输出组件；输出组件包括输出齿轮和输出轴；输出齿轮包括衬套及齿圈，衬套与齿圈之间设置有摩擦部；输出轴设于衬套内，输出轴具有用于与锁芯轴配合连接的连接腔，连接腔内设置有具备径向弹力的弹性部。本发明门锁驱动装置，门锁安装调试时容易使输出轴与锁芯轴同心或接近同心；输出轴同锁芯轴错位时，可通过弹性部的弹力，保证两轴的能够稳定连接，扭矩传动效率高。即使存在过大扭矩输出时，大于摩擦力临界值时，衬套与齿圈之间产生相对滑动，避免打齿甚至断裂情况以及卡顿问题。
