Electronic lock cylinder and electronic key

Abstract

The invention discloses an electronic lock cylinder and an electronic key. The electronic lock cylinder and the electronic key work in a matched mode. The electronic lock cylinder comprises an outer fixing sleeve, a lock cylinder body, an electromagnet, an armature integrated with a linkage part, a following spring, a code identification and control circuit, a touch triggering device and an unlocking execution device. During use, when a code is right, the armature is attracted by the electrified electromagnet in place and not moved by the following spring, so that the touch triggering device is allowed to further trigger the unlocking execution device to execute unlocking operation; and when the code is wrong, the electromagnet is not electrified, the armature and the linkage part are pushed and pressed by the following spring to move and separated from the surface of a sucker of the electromagnet, the unlocking execution device is locked and cannot execute unlocking operation, and the electronic lock cylinder is kept locked. According to the electronic lock cylinder, force is applied by the touch triggering device, and a mode that work is done by moving the armature through attraction of the electromagnet is replaced, so that the power consumption of the electronic lock cylinder is greatly reduced. The electronic lock cylinder is matched with the electronic key.

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
