Lock core, electronic key and unlocking method

Abstract

The invention relates to the technical field of a lockset, an electronic key used for unlocking the lockset and a method for unlocking a mechanical electronic lock, in particular to a mechanical electronic lock, an electronic key and an unlocking method. In the mechanical electronic lock, a key hole of a lock core is made into a round through hole; a driving plate is sleeved in the through hole; a lower marble corresponds to a driving plate; a turnplate drives the driving plate to rotate; the driving plate is a cam with the smooth wheel face without a catastrophe point; when the driving plate rotates, the lower marble pressed against the wheel face of the driving plate is pushed to make straight reciprocating motion; and during the rotating process of the driving plate, friction sound and acting force between the lower marble and the driving plate do not have the situation of sudden variation, an unlocking position can not be detected, the performance of burglary prevention of the lock core is high, a metal key is not required, and the lockset can be matched with the electronic key to realize unlocking with convenient use, safety and reliability. The electronic key controls a stepping motor through a program storage control device to automatically drive an unlocking rotating shaft to rotate so as to realize automatical unlocking with convenient use.

Description

Technical field: [0001] The present invention relates to the technical field of a lock, an electronic key for opening the lock and a method for unlocking, and more specifically relates to a lock cylinder, an electronic key and a method for unlocking. Background technique: [0002] At present, locks are mainly divided into two categories - mechanical locks and electronic locks. [0003] Mechanical locks include tumbler locks, combination locks and the like. The pin lock is a combined locking mechanism composed of a pin, a rotating core and a sleeve. The lock bolt is indirectly controlled by a metal key through the lock core. Its advantages are large number of codes on the lock core, high security, small size and low production cost. , suitable for making various locks such as door locks, drawer locks, luggage locks and padlocks. Its defect one is that because the marble is exposed in the keyhole, a special tool called a trial key is used to hook the marble to the unlocking ...

AI Technical Summary

Problems solved by technology

Its defect one is that because the marble is exposed in the keyhole, a special tool called a trial key is used to hook the marble to the unlocking position through the keyhole from the outside; the second is that the metal key is easy to be copied; the third is that it is very uncomfortable to carry multiple keys. convenient

Its advantages are that the amount of coding is large, the security is high, and there is no need to use metal keys. Its disadvantages are that the lock bolt is controlled by the lock groove on the dial, and the lock core is large in size, so it is not suitable to be made into a small lockset; The bolt presses on the dial wheel surface, when the lock groove on the dial turns to the lock bolt position, the friction sound and force between the dial and the lock bolt will change

The disadvantage is that the electronically controlled lock body is bulky, requires power, and is difficult to open in an emergency. Generally, it is only made into a door lock.
