Abstract

A clutch control electric lock controlled by a micro-computer consists of a key, a night lock core, a lock core seat, a lock body and an electric-control circuit; the invention is characterized in that an electronic password circuit is arranged in the key of the lock; the electrode of the circuit is connected with an electrode contact at the top end of the key; the key has the function to open the night lock core; the key and the lock are mutually universal; one key can open a plurality of electric locks; one electric lock can be matched with a plurality of keys. When the key is inserted into the lock core, the password circuit on the key is communicated and accessed with an electric control system; the system carries out decoding processing; a system control motor accordant with the password carries out the shifting control on the drive deflector rod of a switch lock; the rotation of the key can drive a lock bolt to move to open or close the electric lock; when the decoding password is not accordant, the electric lock is in a neutral gear; the key idly rotates the lock core and can not move the lock bolt, thus realizing the function of the electric lock. The clutch control electric lock controlled by a micro-computer has the beneficial effects of not only inheriting the reasonable and skillful mechanism of a mechanical rim night latch, but also adopting the electronic password technology, in particular adopting the electric control clutch and key standardization technologies to lead the mechanism to be simple and reasonable, more convenient, more practical and more reliable.

Description

Clutch-controlled electronic lock

Affiliated technical field

The present invention relates to a kind of door lock assembly device of microcomputerized control, the driving driving lever of cryptographic technique that especially adopts electronics real-time coding decoding and control system door lock carries out clutch for clutch control, adopts the electronic lock of standardized key and management system thereof.

Background technology

The mechanical billiard door lock is perfect through the improvement of last a century, and it simple in structure ingeniously rationally can be rated as classics, and the key that especially people held has played the power transmitter effect of password to decipher device and locking bolt switch.Just because it is pure mechanical mechanism, and simple in structure, having the pellet shot from a slingshot password can be cracked, so that it can be by the shortcoming of illegal unlatching.

At present; Electronic lock all is to have abandoned the mechanical key that plays ingenious effect in the former pin tumbler lock basically on the known society; Its effect is divided into two: password to decipher is born by keyboard, IC-card, radio-frequency card, information button, fingerprint recognition etc., and the unlatching of locking bolt is then by handle or motor-driven.The electric control principle that handle is unblanked is the reduction of a latch of electrical control, can block the handle axis of rotation, allows or forbids handle rotation; The motor auto-unlocking is that the driven by motor locking bolt is opened and closed, and the shortcoming of this dual mode is that electrical control actuator (automatically controlled latch, automatically controlled locking bolt) can both receive the external force effect at non-driving direction, mechanical displacement may take place, distortion causes automatically controlled inefficacy.

Summary of the invention

In order to inherit the ingenious reasonable mechanism of mechanical billiard door lock; Overcoming it can be by illegal shortcoming of opening; The present invention provides a kind of clutch-controlled electronic lock; This electronic lock has not only used similar traditional key but electronic cipher with software real-time coding decoding is opened door lock, and has adopted driving driving lever to switch lock to carry out electric control clutch and avoided electrical control actuator in the existing electronic lock can receive the deficiency of outside destroy effect, makes it practical more reliable.

The technical solution adopted for the present invention to solve the technical problems is: clutch-controlled electronic lock is made up of key, tapered end and lock body and control circuit board; It is characterized in that: the electronic cipher circuit is housed in the key; The electronic cipher circuit has one to export the electrode contact that is connected to the key top through insulating protective layer, and key body, cylinder lock core body and lock core base are circuit ground; Key body has out the teeth of lock cylinder, is manufacturer's standard machine-shaping, and the key of standards is general each other with lock, and a key can be opened a plurality of electronic locks, and an electronic lock can be joined many keys.Every key is different to the electronic cipher of each electronic lock, and the electronic cipher of at every turn unblanking also changes.An elasticity friction electrode contacts is arranged on the lock core base; In the lock cylinder in the tapered end, an elastic electrode contact is housed, the outside metal ring electrode of lock cylinder is linked through electrode output circuit plate in the elastic electrode contact; Be connected to elasticity friction electrode contacts through friction again; And then be connected on the control circuit board through cable, realized that the electronic cipher circuit is connected on the electric-control system on the key, electric-control system carries out decoding processing or key management to it.Cryptogram decoding meets, and system control small-power direct current generator drives the action of putting into gear of clutch movable body, and the locking bolt driving lever inserts the notch of locking bolt, and key rotation lock cylinder just drives the locking bolt driving lever and rotates, and mobile locking bolt opens or closes electronic lock; Cryptogram decoding is incongruent, because normality is a neutral, the locking bolt driving lever leaves the notch of locking bolt, and the small-power direct current generator is failure to actuate, and key rotation lock cylinder can only drive the idle running of locking bolt driving lever, can not move locking bolt.So just realized that the key that electronic cipher meets can open or lock electronic lock, on the contrary then can not purpose.

The invention has the beneficial effects as follows, promptly inherited the reasonable ingenious mechanism of mechanical billiard door lock, adopted electronic cipher technology again, especially adopted electrical control put into gear clutch and key standardized technique, make it mechanism's advantages of simple, more convenient and practical reliably.
