Disclosed is an electronic lock cylinder, comprising a mechanical rotation core (2), an electronic rotation core (3), a barrel-shaped housing (1) with both ends opened for accommodating the mechanical rotation core (2) and the electronic rotation core (3), and a retainer rod (32), wherein the mechanical rotation core (2) and the electronic rotation core (3) are fixed axially to each other via an electromagnet core (35), and the mechanical rotation core (2) and the housing (1) are fixed to each other via the retainer rod (32). When the core (35) is retracted, the mechanical rotation core (2) and the electronic rotation core (3) can rotate through a certain angle with respect to each other, and the retainer rod (32) is moved such that the mechanical rotation core (2) and the electronic rotation core (3) are fixed to each other and rotate together, now rotating the electronic rotation core (3) by using an electronic key (60), and a deflector rod (300) of the mechanical rotation core (2) is driven to rotate such that the lock is unlocked. Further disclosed are an electronic lock system comprising the above-mentioned electronic lock cylinder, and a method for unlocking a lock. An axial fixation between the electronic rotation core (2) and the mechanical rotation core (3) in the electronic lock cylinder is achieved by utilizing the electromagnet core (35), such that the electronic lock cylinder has a fast response speed, a small volume and a simple structure. |
