Description

A kind of quick door lock

Technical field

The utility model relates to door lock hardware article, relates in particular to a kind of intelligent door lock.

Background technology

At present, Household door lock mainly taking door lock bitting as main, also have plenty of coded lock and Fingerprint Lock, these two kinds of locks are all unblanked cumbersome, use and inconvenient.

The door lock of the three types also having in addition.

The first kind, magnetic card lock, conventionally similar with we gate inhibition used, generally be applicable to entrance guard place downstairs, this class lock power supply is contained in to be locked, and utilizes gate inhibition near lockset, and lockset is opened automatically, can open the door easily, once this class lock power supply goes wrong, and does not open door, manages multiple door locks especially a people, or when turnover for a long time, be a very serious deficiency; Easily be replicated, very dangerous; Be not easy extended function; After magnetic card is lost, be difficult for changing in time password; Magnetic card is not intelligent, without anti-exploration unlocking function.

Equations of The Second Kind, remote-controlled lock, this lock is similar to the lockset on automobile, utilizes telepilot to open the door, and easily, but to be easily replicated be also unsafe to this authentication signal, and due to the power supply of this type of lock, to be arranged on door upper simultaneously, not having electric in the situation that, just pretty troublesome.

The 3rd class, IC-card, it is upper, also inapplicable in family expenses or office door that this class lock is used for the door in hotel, has two large shortcomings, and 1, the principal feature of IC-card design is also not charged itself, lock is held will electric power system; 2, the cryptographic algorithm problem of IC-card, if all locksets adopt a set of cryptographic algorithm, once algorithm is lost, risk is too large, if a set of cryptographic algorithm of every lock set, the general of IC-card just goes wrong.

Summary of the invention

In order to solve above technical matters, the utility model provides a kind of electron key that the intelligent door lock of power supply and authentication signal is provided to lockset.

The utility model is to realize like this, quick door lock comprises lockset and key, in described key with thering are storer, authentication signal generator and four lead-out terminals on lithium battery, chip board, chip board, wherein two terminal output currents, two other terminal output authentication signal, the multiple random ciphers of memory stores in described key, in described lockset, micro motor is set, circuit board, on circuit board, there is storer, random cipher generator, random cipher produces input key, triode signal amplifier, authentication signal receiver, four input terminals, wherein two terminals are that described key lead-out terminal provides electric current, two terminals are that described key provides input authentication signal, the multiple random ciphers of memory stores in described lockset, in described lockset, door handle is connected with dead bolt, door handle rotates and drives dead bolt to move left and right, on described dead bolt, be provided with two gears, described micro motor is connected with a pin, motor rotarily drives pin and moves forward and backward.

For fear of cumulative errors, without stepper motor, and adopt micro dc motor that power is provided.In order to solve the stuck problem of motor, the friction force that the design adopts magnetic pull to produce, carrys out transmitting power, exceedes this friction force, and motor can also freely rotate.The stuck gear train that can not only destroy in micro motor of motor, also produces simultaneously and exceedes 5 times of above electric currents of normal work, and the normal work of chip, lithium battery is caused and had a strong impact on, and also consumes a large amount of electric energy simultaneously, and concrete scheme is as follows.

On described micro motor output shaft, be provided with two circular magnet, one is fixedly connected with micro motor output shaft, and another piece is slidably connected and is fixedly connected with described pin.

In described lockset, there is a knob at the back side, and described knob connects another pin, and knob rotarily drives connected pin and moves.

The described unlock button that is provided with on the key.

The each generation 12 of described random cipher generator is random cipher, and 12 for random cipher is 255 systems, and wherein first six digits is variable, fixes for latter 6.

The beneficial effects of the utility model are key new style, fashion, save unnecessary metal key, are only with an electron key just; Door lock need not be installed power-supply system, and key lastblock lithium battery just can be used several years, rushes to electricity and can also continue to use; Lock structure is simplified, and is convenient to manufacture, and saves starting material; Key is lost one, or key lends after other people, suspects and has people to join the key of oneself, keeps the change people and changes lock core, also need not change key, as long as open strip of paper used for sealing, clicks button, has produced a new password just; All functions, comprise and change password, and new bitting, nullifies key, do not need additional apparatus such as computer, and only key and lock just can complete.

Brief description of the drawings

Embodiment

The utility model illustrates by reference to the accompanying drawings.

As shown in Figure 1, comprise lockset and key.

Lockset comprises lock end single-chip microcomputer, four input terminals, password generation button, and key comprises lithium battery, four lead-out terminals and unlock button.

With new key, by arriving lockset contact jaw, the random cipher of clicking lockset end produces and sends button, and key has just been write down the password of lockset like this.In like manner, click password and send button, can mate multiple keys.These two buttons at ordinary times need not, be hidden in the indoor panel of lock the inside of door.Equally, reason, a key also can record the password of multiple locks, is not with so much key as far as possible, has been with an electron key just.

Key belongs to power-down mode at ordinary times, when substantially without electric energy, only opening, lock, is just waken up, and finishes the work and only needs several seconds, then power down dormancy again.

While unblanking, click unlock button on the key, tap lock end with key, now Lock control system has had electric energy, starts working.

Lockset sends first 6 of 12 passwords (capable of regulating) to key, key finds corresponding whole 12 passwords by front 6 passwords, sends to lockset, and it is correct that lockset end is analyzed password, controls revolution, unblanks.

The similar process of unblanking of locking process, just need not click key button, directly taps lockset just with key.Wherein use 4 triodes and circuit board and coordinate, can control direction of current, reach and control motor forward

Object with reversing.

While unblanking, to click unlock button on the key, when locking, need not press.Because click after unlock button, in the time period arranging at lock, add a numeral 01 after the password that key sends, for the difference of locking.

No matter key end, or lock end, if receive continuously and meet the cipher code set feature setting, but be again wrong, lockset and key program all can enter endless loop, no longer work, or short circuit current is provided, to guard against malice to sound out password.

12 passwords that set are 255 systems, and are random generations, and mutual opening rate can be ignored substantially.

As shown in Figure 2, comprise circuit board (1), lockset back side knob (2), knob pin (3), dead bolt (4), door handle (5), motor pin (6), motor (7).

In the time unblanking, key contacts with lockset, click key button, lockset circuit receives after authentication signal, starter motor (7) rotation, and motor (7) drives motor pin (6) mobile, thereby motor pin (6) departs from dead bolt (4), press door handle (5) with hand, door handle (5) drives dead bolt (4) mobile, has so just opened door.
