Abstract

The utility model relates to an intelligent electric mechanical lock, comprising a lock case (1), a bolt (8) positioned in the lock case, an electric machine (2) and a bolt guiding device, and relating to the lock industry. The bolt adopts link mechanisms (6) and (7) to connect with the electric machine. A bulge (15) is arranged in the lock case. When a twisted shaft of a connecting rod approaches the bulge, the center of the twisted shaft is positioned in the lower part of the bolt. Thus, the bolt can realize self locking, prying prevention, simple structure and safe use.

Description

The intelligent electric machine lock

Technical field the utility model relates to a kind of lockset, especially a kind of motor-driven intelligence lock.

Background technology is along with the sound development of national economy, and the people's living standard improves constantly, and building conversational system has entered common people house.Supporting with it electric control door lock has also been passed by from the automatically controlled electromagnetic lock that is locked into, and arrives the distance of electromechanical locks again.On the market electromechanical locks has appearred in recent years, but the structure more complicated, can not self-locking.

Summary of the invention the utility model is exactly a kind of intelligent electric machine lock that designs for the defective that overcomes the common electric machine lock.Comprise lock box, place dead bolt, motor and the dead bolt guiding device of lock box, dead bolt links to each other with motor by linkage.One projection that is fixed on the lock box is arranged in the lock box, and this projection makes the twisted axis of connecting rod near projection the time, and being centered close to below the dead bolt center line of twisted axis realizes the self-locking of dead bolt.Linkage of the present utility model is realized self-locking, and noise is low, and the life-span is long, also can use as usual during power failure, can also control by remote interlocking, can add a feedback signal, is the preferred of common electric machine lock update.

Description of drawings Fig. 1 is the vertical view that the utility model removes lock box cover, and Fig. 2 is a sectional drawing, and Fig. 3 is a dead bolt box plan view, and Fig. 4 is an electrical schematic diagram of the present utility model.

The specific embodiment is equipped with micro machine 2 in lock box 1, duplex no-load voltage ratio reduction gearing 4, working gear 5, drive connecting rod 6, follower link 7, dead bolt 8, main door inductive probe 9, control circuit board 10, drive connecting rod 6 is coaxial with the working gear 5 and the knob 11 that opens the door, drive connecting rod 6 is connected with follower link 7, connecting rod lead 14 is riveted on the dead bolt 8 (consults Fig. 1～shown in Figure 3,), projection 15 in the lock box is riveted on the lock box, the distance of end distance dead bolt center line is more than or equal to connecting rod twisted axis radius on this projection outer rim, in the present embodiment, the twisted axis radius is 5cm, and correspondingly the distance of end distance dead bolt center line can elect 5 as on this projection outer rim, 5.2,6,8.After powering on, microprocessor on the control circuit board 10 is by the signal of main door inductive probe 9 and secondary door inductive probe 13, drive micro machine 2 forward or reverse, deceleration, no-load voltage ratio by duplex no-load voltage ratio reduction gearing 4, drive working gear 5 rotations, make coaxial drive connecting rod 6 rotate in the same way simultaneously, follower link 7 is by connecting rod lead 14, drive dead bolt 8 is done and is stretched out or the indentation campaign, reaches the purpose of closing the door or opening the door.When going out, can drive coaxial working gear 5 rotations, reach the purpose of opening the door by the knob 11 that turns to open.When entering, can use key rotary work gear 5, reach the purpose of opening the door.

Control circuit board 10 comprises microprocessor U2, motor-drive circuit, signal acquisition circuit, auditory tone cues electric circuit (consulting Fig. 4).D1, U3, C2, C5 provide power supply to U2; R10 and C4 form reset circuit; U1 is an optocoupler, is used for gathering the signal of telecommunication; At closing time, door inductive probe GM provides door lock to close signal by 9 pin of U2, and R2 is a pull-up resistor, and C3 is a filter capacitor; U2 locks a door by 17 pin and 18 foot control system micro machine M1 rotation then, and N2, N3, P1, P2 are triodes, and R5, R6, R7, R8 are current-limiting resistances, and C1 is a filter capacitor; When opening the door, the signal of telecommunication, turns to open by 17 pin and 18 foot control system micro machine M1 after U2 collects signal by 1 pin of U1 to U2, goes out signal through 10 human hair combing wastes simultaneously, drives buzzer FM and sends prompt tone, and R1 and N1 are the drive circuits of buzzer FM.
