Compared with an electronic lock in a whole lock form, the electronic lock cylinder has low cost and is installed in a similar manner to a mechanical lock cylinder, so that the electronic lock cylinder has received wide attention.

However, the internal mechanical structure of the electronic lock cylinder is very compact, and the internal space is difficult to accommodate structural components required for mechanical unlocking and electronic unlocking at the same time. Thus, the existing products are basically single-function electronic lock cylinders, in which the mechanical unlocking function is omitted and the electronic lock cylinder part, which is driven electronically, is the main part.

Chinese patent application CN201510760277.9 discloses a method for realizing an electronic lock core. The electronic lock cylinder disclosed in this application includes a front handle and a rear handle. The front handle includes a fingerprint, password authentication system and the rear handle includes associated authentication electronics. The front handle and the rear handle are integrated and can rotate freely together. The rear handle shell and the thumb wheel are integrated, and the rotation of the rear handle can bring the thumb wheel to rotate so as to achieve the purposes of opening and locking the door. When the identity authentication is not correct, the inner parts of the front handle and the rear handle are in free idle state and can not drive the thumb wheel to rotate, so that the door can not be opened or locked. The rear handle is internally provided with a clutch. After proper identity authentication (e.g., by a fingerprint or password), the interior of the rear handle is connected to the housing of the rear handle by movement of the clutch within the rear handle. At this time, the front handle is rotated to drive the inside of the rear handle to rotate, and the inside of the rear handle is rotated to drive the rear handle shell to rotate, so that the driving wheel is driven to rotate, and the aim of opening or locking the door is fulfilled.

Chinese patent application CN 201520877874.5 discloses an electronic lock cylinder. The outside of the electronic lock cylinder (the outside mounted with respect to the door) has a handle. The inside of the handle is provided with fingerprint identification, bluetooth and other relevant components, and a clutch is arranged. After the user passes through fingerprint identification, the clutch in the driving handle is combined with the lock cylinder body, and then the lock cylinder inner thumb wheel can be driven to open the lock tongue by rotating the outer handle. The electronic lock core can not be mechanically unlocked by a key, and belongs to a single-function electronic lock.
