Abstract
The invention discloses an intelligent full-automatic conversion lock cylinder, mainly composed of the following parts of a key, a marble cylinder, a movable sleeve, a small magnet, a movement spring, a double-ear roller, a cam, a direct-current reducer motor, a thrust spring, a movable pulley, a movable sleeve, a single chip computer, a key sensing switch, a motor drive and over-current detection circuit, a communication interface, and the like. When a spring bolt moves to the end of one direction, the motor and the cam are locked and the double-ear roller cannot withdraw because of the left end thereof clamped in a groove of the cam so that the electromechanical transformation cannot be carried out. However, under a normal condition, the motor is driven to stop rotating and then to rotate reversely by the single chip computer so as to relieve the extrusion to the double-ear roller so that the double-ear roller can move leftwards and rightwards for the electromechanical transformation under the action of the spring. If the circuit goes wrong, the motor is driven to rotate rapidly and reversely by the single chip computer when the key is inserted and the key sensing switch is switched on and the double-ear roller cannot withdraw because of the clamped left end when the motor is blocked so that the right end of the double-ear roller cannot be inserted into the groove of the cam, and therefore, the cam cannot be driven to rotate to open the lock by the key.
Description
Affiliated technical field
The present invention relates to a kind of electronic lock cylinder, especially the sort of electromechanics is the electronic lock cylinder of conversion automatically.
Background technology
As everyone knows, existing electronic lock especially Fingerprint Lock has high theftproof performance, and does not need key, and is easy to use.But electronic lock also has reliability scarcely.The unreliability of electronic lock mainly shows two aspects, and the work of the first Fingerprint Lock time needs power supply, in case run into have a power failure or running down of battery the time just can not work, just do not drive lock; It two is that electronic lock is made up of many electronic components, though present reliability of electronic components is very high, is not absolutely reliable, and just cisco unity malfunction of electronic lock is not just driven lock in case certain electronic component breaks down; It three is that electronic component all has certain application life.Mechanical lock is then different, have high reliability, but especially fingerprint is phase-locked more relatively poor than theftproof performance with electronic lock, and needs key, and key carries inconvenience, forgets easily and loses.A kind of electronic lock cylinder is arranged now, have fingerprint, password, three kinds of modes of key to select, though guaranteed the reliability of lock, its theftproof performance is had a greatly reduced quality, and its theftproof performance and common mechanical lock are suitable, has not given play to the theftproof performance of Fingerprint Lock.Also have a kind of electronic lock cylinder with electromechanical transformation apparatus, though also can carry out electromechanics conversion, its switching mechanism needs electric energy to drive, if outage or battery power deficiency but can't be changed when circuit breaks down.
Summary of the invention
Indulge the above, the present invention is intended to design a kind of electronic lock cylinder, this lock core just often can only be unblanked with password, fingerprint at circuit, drive motors, gear, if have any a part of circuit break down (comprising fingerprint module) or drive motors, gear breaks down or outage, electric energy are not enough just can carry out electromechanics conversion, back outage or battery power deficiency also can dynamo-electric be changed even circuit breaks down, open the lock with the key, so not only guaranteed the theftproof performance of lock core but also guaranteed the reliability of lock core.
The present invention's technical scheme of being taked of dealing with problems is: the present invention mainly is made up of intelligence control circuit and dynamo-electric lock core.Intelligence control circuit mainly is made up of single-chip microcomputer, over-current detection circuit, key inductive switch, motor drive circuit in bi-directional, communication interface etc.The I/O mouth of over-current detection circuit, key inductive switch and single-chip microcomputer is electrically connected.Dynamo-electric lock core mainly by DC speed-reducing, lock cylinder, dynamo-electric clutch, have key, the key inductive switch constitutes.Dynamo-electric clutch by thrust spring, connect pulley, quill, cam, left and right sides ears roller bearing, move a spring, small magnet constitutes, left and right sides ears roller bearing flexibly connects; The driving of dead bolt is finished by cam, and on the fixing same support of dynamo-electric clutch and lock cylinder, DC speed-reducing is fixed on support one end, and the key inductive switch is installed in the small magnet lower carriage.Thrust spring, connecting pulley all is enclosed within on the output shaft of DC speed-reducing, thrust spring is preceding, one end heads on the connection pulley, flat of the other end of connection pulley is inserted in the middle groove of quill, and the symmetrical double flute of the other end round edge of quill is inserted by an end of the ears of left ears roller bearing, the other end of the ears of left side ears roller bearing inserts the groove of cam center, the another side of cam is close to right ears roller bearing, the right ears roller bearing other end inserts in the lock cylinder rotating cylinder draw-in groove and is pressing and moves a spring, move a spring other end and supporting small magnet, the other end of small magnet faces lock cylinder lockhole one end.When circuit, motor, power supply, (fingerprint module is normal), motor rotates by the connection pulley in the dynamo-electric clutch, quill, left ears roller bearing and drives cam rotation, cam tongue with lock moves, after dead bolt moves into place, by blocking tightly, at this moment over-current detection is to over current of motor and notify single-chip microcomputer under the effect of the moment of motor for dead bolt stop motion, cam, single-chip microcomputer reverses by motor a little by the motor drive circuit in bi-directional, unclamps the cam that blocks.When having to promote small magnet after key inserts lockhole and travel forward the time, the conducting of key inductive switch, key sensor circuit notice single-chip microcomputer, at this moment if circuit, motor, (fingerprint module) are undesired, have key and promote small magnet, a spring is moved in small magnet extruding, and right ears roller bearing inserts ears in the groove of cam center under the elastic force effect of moving a spring, at this moment rotates to have key and can drive cam rotation and open and close lock; If circuit, motor, (fingerprint module) are normally, single-chip microcomputer allows cam block by the motor drive circuit in bi-directional by the motor counter-rotating once more.After cam blocked, left ears roller bearing was stuck in the groove of cam center, even a spring is moved in the compression of the small magnet of key promotion at this moment, the ears of right ears roller bearing also can't be got in the groove of cam center, and standby key can only dally.After standby key was extracted, the ears of left ears roller bearing can insert in the groove of cam center in the effect of thrust spring again, and machine performance converts motoring condition once more to.Ifs circuit breaks down or electrical fault or communication module such as fingerprint module fault, cut off the power supply again or the battery power deficiency, at this moment insert standby key, though the conducting of key inductive switch energy is because of outage, electric energy deficiency, motor akinesia, cam can not blocked yet, left side ears roller bearing can not be stuck on the cam yet, moves a spring like this and can get into cam by right ears roller bearing, and standby key just can have been unblanked like this.
The invention has the beneficial effects as follows: the high theftproof performance of existing electronic lock cylinder, the mechanical lock height reliability is arranged again, unblank at ordinary times to be with key, very convenient to use.
