Abstract

The utility model relates to an electronic lock with composite structure of IB card and codes. The structure also comprises an IB probe head arranged on a panel of an outer casing body, and code keystokes arranged on the middle part of the panel. The IB probe head and the code keystokes are respectively connected with an electronic circuit board which is internally arranged. The electronic circuit board is provided with a chip control circuit connected to an electromagnetic clutch mechanism. The electronic lock with the composite structure has the advantages of more reliable and confidential performance, flexible use, low error rate, and high preciseness rate According to advance preset, the IB card and codes can be singly and respectively used for opening locks, and can be also compositely used.

Description

IB card and password composite construction electronic lock

The utility model belongs to the door lock assembly field of electronization, specially refers to the electronic lock structure of a kind of IB of utilization card and password compound action.

The present electronic lock of extensively selling on the market, kind is existing a lot, most of existing electronic lock structure more complicated, the volume ratio of lock housing is huger, also there is certain error probability, in order to overcome defectiveness, I once studied IB card electronics lock gall, and had declared national patent with regard to " IB card electronics lock gall " for topic at the beginning of 99, had now authorized, it becomes compact conformation in many electronic locks, error probability is little, the better product that theftproof is strong, but also feel to exist certain limitation in being to use, that is exactly, this lock is only recognized the instruction of IB card, in case lose the IB card, whole lock just can't move and come to an end, the frequent again appearance of probability that slight IB card is often lost or temporarily be can not find, it is more passive to cause to the user.For this reason, just wish that designing a kind of use again locks flexibly, it can use the IB card to unblank separately under the normal condition, also can access to your password separately and unblank, also can set double insurance, unblank to access to your password simultaneously again with the IB card earlier, when all conforming to setting signal, buzzer provides unlocking signal, and the twisting door knob can drive rotating shaft and unblank, certainly this class is locked in some necessary mechanisms or uses under secret situation, it has more reliable confidentiality, also has certain changeability, flexibility.

The purpose of this utility model, be big in order to overcome in the existing mechanical electronic lock complex structure volume, the defective that certain error probability is arranged, and it is single during with the IB kayser, can't handle the passive situation of losing under the IB card situation flexibly, and redesign a kind of by the IB card of circuit chip control and the electronic lock of password composite construction.

The utility model is to rely on following technical scheme to realize, a kind of IB card and password composite construction electronic lock, mainly comprise the shell body, handgrip of lock, inner electromagnetic clutch mechanism, it is characterized in that, also comprise the IB probe that is arranged on the shell body panel, the password key that is arranged on the panel middle part in this structure, they are connected on the inner electronic circuit board that is provided with, and are furnished with the chip controls circuit on the wiring board, and it is connected to electromagnetic clutch mechanism.

Chip controls circuit on the described internal electron wiring board, it comprises the power circuit part that contains rectification, filtering; Coupled, be the signal circuit section that contains buzzer; This part is connecting the driving circuit section of carrying out power amplification; Be connected to the information-processing circuit that has IB card probe by chip; And the switching circuit portion that contains password key, this 5 partial circuit all is connected on the singlechip chip.

The good effect of this programme is, this composite construction electronic lock has more reliable, more secret performance, uses flexibly, error rate is low, according to prior setting, can use IB card and password unlocking separately respectively, also can compoundly use, unblank by dual fail-safe, chip controls accuracy rate height, and compact conformation, easy to make.

Further specify embodiment below in conjunction with accompanying drawing:

Description of drawings:

Fig. 1 is this electronic lock housing face-plate elevation;

Fig. 2 is this electronic lock side structure sectional view;

Fig. 3 is circuit theory diagrams on the internal circuit board.

Among the figure, 1 is composite construction electronic lock shell, its panel top is provided with IB probe 2, the middle part is provided with password key 3, valid password one has 6, inside is provided with electronic circuit board, be furnished with chip controls circuit 4 on it, this control circuit includes power circuit part 4.1, contains the signal circuit section 4.2 of buzzer, carries out the driving circuit section 4.3 of power amplification, the information-processing circuit 4 that has IB card probe, 4 and contain the switching circuit portion of password key, what be connected with circuit board has an electromagnetic clutch mechanism 5, and coupled turning handle 6 is driving rotating shaft 7 and realizing unblanking and shutting.
