Clutch device of electronic door lock and electronic door lock
The invention discloses a clutch device of an electronic door lock and the electronic door lock. The clutch device is used for being linked with an electric device, a lock body and a lock cylinder of the electronic door lock. The clutch device comprises a driving square rod, a driven square rod, a driving gear, a driven gear, a synchronous gear, an ejector rod, a cam and a limiting mechanism. The synchronous gear is rotatably connected to the ejector rod; when the ejector rod is located at the first position, the synchronous gear is synchronously meshed with the driving gear and the driven gear; when the ejector rod is located at the second position, the synchronous gear is completely separated from the driving gear and the driven gear; the cam is located on the side, away from the synchronous gear, of the ejector rod and is synchronously and rotationally connected and fixed to the lock cylinder inner cylinder. The cam is provided with a cam groove, and the sliding block movable pin of the ejector rod moves in the cam groove along with rotation of the cam to drive the sliding block to be switched from the first position to the second position. The limiting mechanism enables the ejector rod to be kept at the first position or the second position. Therefore, it can be guaranteed that the mechanical key can always open the electronic door lock, and safety is high.
本发明公开了一种电子门锁的离合装置及电子门锁，该离合装置用于分别与电子门锁的电动装置、锁体和锁芯相连动；该离合装置包括主动方杆、从动方杆、主动齿轮、从动齿轮、同步齿轮、顶杆、凸轮和限位机构；同步齿轮可转动地连接于顶杆；该顶杆位于第一位置时，同步齿轮与主动齿轮和从动齿轮同步啮合；该顶杆位于第二位置时，同步齿轮与主动齿轮和从动齿轮完全分离；凸轮位于顶杆远离同步齿轮的一侧，该凸轮同步转动地连接固定于锁芯内筒；凸轮设有凸轮槽，顶杆的滑块活动销在凸轮槽内随着凸轮的转动而运动，带动滑块从第一位置切换到第二位置；限位机构使顶杆保持位于第一位置或第二位置。以此可保证机械钥匙始终可对电子门锁进行开启，安全性高。
