Electronic lock cylinder and electronic key

Abstract

An electronic lock cylinder structure, comprising an outer fixed sleeve (13), a lock cylinder body (21), an electromagnet (4), an armature (6) integrated with a linkage piece (5), a follower spring (3), a code recognition and control circuit IC capable of utilizing the battery of a key to supply power, a contact triggering device, and an unlock execution device. When the code is correct, the armature (6) is held in place by the energized electromagnet (4) without moving with the follower spring (3), thus allowing the contact triggering device to further trigger the unlock execution device to execute an unlocking action. When the code is incorrect, the electromagnet (4) is not energized; the armature (6) and the linkage piece (5) are pushed and pressed by the follower spring (3) so as to move away from the attraction disc surface of the electromagnet (4); the unlock execution device is locked and cannot execute the unlocking action, and thus the electronic lock cylinder remains locked. Also disclosed is an electronic key for use with the electronic lock cylinder.

Description

technical field [0001] The invention relates to an electronic lock core and its actuator, in particular to a passive electronic lock core. Background technique [0002] Electronic passwords have many advantages. For example, the possibility of repeated codes is very small for a large amount of data. Passwords can be written according to needs and have strong function expansion capabilities. Therefore, they have been widely used in many fields, such as bank cards, second-generation identity cards, etc. Certificates, medical cards, etc. However, it is very limited in the application of locks, the most traditional safety protection device. [0003] At present, almost all electronic locks on the market are active, that is, the electronic lock has a power supply. Whether electromagnet or motor is used as the driving device of the actuator, it consumes a lot of energy. As a result, the electronic locks we see all put the power supply inside the lock. In fact, this is a last reso...

Another example: Although the solution proposed by the Chinese patent application with the announcement number CN1059775A and the invention name "Electronic Lock Micro-power Consumption Control Mechanism" saves electricity, it can only be used for the transformation of a specific door lock, and the lock pin is directly used to block the lock. The tongue moves, once the handle is twisted hard without using the key, it may cause the lock pin to deform and cause the lock to fail
