Description

The two drive-type clutches of a kind of digital intelligent lock

The mechanical part of using on a kind of safe-guard door lock of technical field particularly is applied to the arrangement of clutch in digital intelligent theftproof lock field.

Background technology has a kind of digital intelligent safe-guard door lock in the market, as long as the key of band password is near lockhole, identification chip in the lockhole promptly sends instruction, the micro machine action, drive is installed in the clutch operating between door handle and the lock core shifting block, door handle and lock core shifting block are combined as a whole, and this moment, swing handle could be opened door.Otherwise clutch is in the disconnection situation, and promptly door handle separates with the lock core shifting block, and at this moment swing handle in any case all can not be opened door.

Theftproof lock is a kind of specialty goods, requires function-stable, and strict guarantee does not go wrong, the phenomenon of the door that do not occur not opening.All there is limitation in the existing clutch of using as the digital intelligent theftproof lock, and very difficult assurance is not made mistakes, and it is perfectly safe to accomplish.Add the easy break-down of electronic component own, cause electronic system can not send out instruction sometimes, the lock of not opening is not opened door.To be on the safe side, present digital intelligent lock also is provided with the hidden mechanical unlocking system of a cover as standby except a cover electronics unlocking system is arranged.In fact, if there has been this to overlap hidden mechanical unlocking system, that will not make the anti-theft feature of digital intelligent lock be reduced to the same with the standard machinery theftproof lock.This situation makes the people feel awkward really, and is off guard not all right, be equipped with and reduced function, what to do?

The digital intelligent lock clutch generally adopts screw or gear type at present, directly drives by micromachine.Because electric motor starting moment is less, and required moment is bigger during clutch operating, therefore causes starting current big, or burns out motor, or make shorter battery life, and voltage drops to 4.5 volts to be difficult to start when following.Clutch blocks easily in addition, can not carry out unlocking function.

01257585.2 number patent has proposed a kind of " Worm-gear type clutch ", though can prolong battery application life, voltage is lower than 4.2 volts still can operate as normal, but the clutch noise ratio is bigger, still have the possibility of blocking, still do not break away from the predicament that hidden mechanical unlocking system need be set.

The summary of the invention the purpose of this utility model provides a kind of digital intelligent lock with two drive-type clutches, accomplishes to use the bielectron command system, and mechanism is flexible, function-stable is reliable, and prolongs battery application life, noiseless.

Technical scheme is the major and minor electronic command of an employing system, commands major and minor driving unlocking mechanism respectively.It is as follows to drive the unlocking mechanism structure: rotary sleeve is in changeing the axle centre bore, changeing axle is enclosed within the casing centre bore, the slide of two long-armed slide blocks is enclosed within respectively on two miniature deceleration direct current generator output shafts, trundle is arranged respectively on two motor output shafts and be set with driving spring.Trundle is clipped in the gap between driving spring circle and the circle and can does relative motion.Long-armed the laying respectively at of two long-armed slide blocks changeed the axle both sides, changes the plug housing that two symmetries are arranged on the axle, and movable latch and back-moving spring are arranged respectively in the plug housing centre bore, and the pin-and-hole of two symmetries is arranged on the axis of rotation.Axis of rotation links to each other with door handle, changes axle and links to each other with the lock core shifting block.The input line of two motors links to each other with major and minor electronic command system respectively.

Operating principle is as follows: when main electronic command system sends unlock instruction, the main unlocking mechanism that drives is started working, its motor just changes, trundle on the motor output shaft is done forward along driving spring turn-to-turn gap and is slided relatively, originally compressed driving spring is crossed trundle by circle and is made stretching routine, the stretching, extension elastic force that driving spring produces will promote long-armed slide block toward changeing 3 millimeters of axle direction displacements, the latch that long-armed slide block just will change in the axle is pressed in the pin-and-hole of axis of rotation, and commentaries on classics axle and axis of rotation are combined as a whole.At this moment turn the handle with hand,, change axle and drive the lock core shifting block thereupon, lock is opened driven rotary axle and rotation of commentaries on classics axle.After three seconds, main electronic command system sends blocking order, the motor counter-rotating, and the trundle on the output shaft is done along driving spring turn-to-turn gap oppositely and is slided relatively, by circle compression driving spring.When driving spring is thrown off the slide of long-armed slide block, the movable latch of changeing in the axle will be under the effect of back-moving spring, push long-armed slide block and move toward leaving the direction of changeing axle, movable latch withdraws from from the axis of rotation pin-and-hole simultaneously, and axis of rotation no longer is connected with the commentaries on classics axle.With it simultaneously, motor stall.Turn the handle this moment, and a driven rotary axle idle running can not be opened lock.If there is fault in main electronic command system, can enable secondary electronic command system so, the secondary work of expense mechanism, its operating principle and top described identical of driving of commander.

Compared with the prior art, the utility model has following characteristics:

1, have two and overlap the executive system of independently commanding and unblank, the daily use of a cover, a cover is standby, mutually noninterfere.When a cover system breaks down, but start another set of operate as normal, therefore do not need to be provided with hidden mechanical unlocking system,, make theftproof performance meet people's ideal from truly having realized the anti-theft feature of digital intelligent lock as standby.

2, the rotating speed of miniature deceleration direct current generator can reach 800 rev/mins, and starting current is steady, and starting torque increases, and mechanism is flexible, thoroughly eliminated the phenomenon that gets stuck, and noise reduces greatly.

3, battery prolongs doubly a lot application life.When cell voltage drops to 3 volts, but operate as normal still.

4, owing to adopt the bolt-type connecting mode, the required moment of clutch itself has reduced a lot, and therefore burning out the motor phenomenon can avoid substantially.
