An electronic lock cylinder, includes a mechanical rotation core, electronic rotation core, barrel-shaped housing with both ends opened for accommodating the rotation cores, and a retainer rod, the rotation cores fixed axially to each other via an electromagnet core, and the mechanical rotation core and the housing fixed to each other via the retainer rod. When the core is retracted, the rotation cores can rotate through a certain angle with respect to each other, and the retainer rod is moved such that the rotation cores are fixed to each other and rotate together, now rotating the electronic rotation core by using an electronic key, and a deflector rod of the mechanical rotation core is driven to rotate such that the lock is unlocked. Further disclosed are an electronic lock system including the electronic lock cylinder and a method for unlocking a lock. Axial fixation between the rotation cores is achieved. |

1. An electronic lock cylinder,
comprising a mechanical rotation core, an electronic rotation core, a barrel-shaped housing with both ends opened for accommodating the mechanical rotation core and the electronic rotation core, and a retainer rod; wherein one end of the housing is a front end, and a position limitation chuck for axial position limitation is provided at the opening of the front end; one end of the mechanical rotation core is a flat deflector rod, wherein the deflector rod is projected out of the front end of the housing, and a rear end of the mechanical rotation core is a first cylindrical cavity, wherein at a position outside of the circle center of a bottom portion of the first cavity, there is a concave; a segment of the wall of the first cavity protrudes in its axial direction, forming a cambered position limitation portion, wherein a mechanical rotation core retainer slot, which is a through slot and in parallel with the axis of the first cavity, is provided at the middle portion of the cambered position limitation portion, dividing the cambered position limitation portion into a first position limitation portion and a second position limitation portion; the electronic rotation core is of a multiple-segment cylindrical shape, wherein one end of the electronic rotation core is a rear end, and at the rear end there are electronic contacts, with the front end of the electronic rotation core being inserted into the first cavity so as to be rotationally connected with the mechanical rotation core, and, an electronic control unit and an electromagnet is disposed in the electronic rotation core, wherein the electronic control unit is connected with the electronic contacts and the electromagnet respectively and controls the action of the electromagnet; a through hole for telescoping of a core of the electromagnet is provided at a position where the front end of the electronic rotation core mates with the concave, and a spring is disposed inside the electronic rotation core such that the core abuts against the spring so as to be projected; a cambered side slot is provided at the front end of the electronic rotation core in the circumferential direction and is used to mate with the cambered position limitation portion, wherein the side slot mates with the cambered position limitation portion in an axial direction, and the side slot is provided with an electronic rotation core retainer slot in the axial direction of the electronic rotation core, dividing the side slot into a first side slot corresponding to the first position limitation portion and a second side slot corresponding to the second position limitation portion, wherein the arc length of the first side slot is larger than or equal to that of the first position limitation portion, and the arc length of the second side slot is larger than or equal to the sum of the arc length of the second position limitation portion and the width of the mechanical rotation core retainer slot; an inner wall of the housing has a housing retainer slot in the axial direction; when locking, the core is projected into the concave, and the housing retainer slot is aligned with the mechanical rotation core retainer slot while staggered with the electronic rotation core retainer slot, wherein the retainer rod is seated within both of the housing retainer slot and the mechanical rotation core retainer slot at the same time; when unlocking, the core is retracted into the electronic rotation core, the electronic rotation core rotates by a certain angle to align the electronic rotation core retainer slot with the mechanical rotation core retainer slot, wherein the retainer rod is moved toward the electronic rotation core retainer slot and is seated within both of the electronic rotation core retainer slot and the mechanical rotation core retainer slot at the same time, enabling the electronic rotation core and the mechanical rotation core to rotate synchronously. |
