In addition to the bolt mechanism of manual clutch, other structures of smart electronics keeper can also be with reference to China's utility model
Content disclosed in patent 201420106144.0.
The on an off of lock body: press the pass button on remote-control key, after lock body receives shutdown signal, motor 24 starts band
Moving gear 25 rotates, and gear driven tooth bar 2 moves, and tooth bar links with latch frame 1, is connected with snap close 21, and door is blocked.Lock
Button and lock pin form the assembled state of upper and lower drift-pin type, and door is tightly coupled into an entirety with doorframe, this have extremely strong solid
Tiger lock pattern qualitatively, it is possible to effectively play pick-proof and anti-riot effect.When press on remote-control key when driving button, electricity
Machine rotates backward, and drives latch frame reversely to move, and lock pin separates with snap close, and door is opened.
When running into burst dangerous situation or natural disaster, need energency-unlocking, and a period of time can not find remote-control key or battery does not has
Electricity or motor break down, it is necessary to manually unblanking, general push rod 5 is integrally fixed on latch frame or tooth bar, by lower push-rod meeting
Making motor reversal, wear and tear electric motor speed reducer gear, and the bolt mechanism of manual clutch can solve this problem.
Emergent operation principle of manually unblanking
Seeing the structure chart of Fig. 1 to Fig. 5 and the operating position graph of a relation of Fig. 6 a-6c, the operation manually unblanked is as follows: door
Under bolt-lock closed state (as shown in Figure 6 a), finger pushes to the right push rod 5 and makes manual unlocking frame 4 move right compression first along slide
Spring, inside manual unlocking frame 4, the wedge shape shoulder 17 of (the first side surface) inwardly promotes the centre in the middle part of elastic on-of pin assembly
Shoulder 15 compresses the second spring 16, and elastic on-of pin assembly 14 retraction is exited described lock slots 11 and unlocked described transmission clutch block 8.
First spring-compressed to a certain extent after, manual unlocking frame 4 starts to promote latch frame 1 to move right, and is arranged on latch frame 1
Transmission clutch block install axle 12 move right.Meanwhile, tooth bar 2 remains stationary as, and is inserted in the transmission in transmission draw-in groove 10
Pin 18 remains stationary as, thus transmission clutch block 8 deflects.After transmission clutch block 8 deflects an angle, trundle 18 is from biography
Dynamic draw-in groove 10 departs from, thus realizes latch frame 1 and tooth bar 2 motion separation.Latch frame 1 moves to limit on the right-right-hand limit position and realizes opening
Lock, limit on the left position (such as Fig. 6 b) stayed by tooth bar 2.
Smart electronics keeper, after carrying out manual emergency and unblanking, typically recovers also to lead to after normal electrical controls at keeper
Cross driven by motor latch frame locking latch.Accordingly, it would be desirable to made transmission clutch block keep before tooth bar 2 moves to limit on the right-right-hand limit position
Deflexion attitude, in order to after tooth bar 2 moves right, trundle 18 can enter transmission draw-in groove 10 smoothly, makes transmission clutch block 8 extensive
Connection again and between tooth bar 2.
When transmission clutch block 8 just deflects, the end of elastic on-of pin assembly 14 is contracted under the effect of lozenges
Laterally in the Part I of elongated hole 7, end is corresponding between lock slots 11 and the described angle limit groove 27 of transmission clutch block 8
Region, described angle alignment pin 28 relative to manual unlocking frame from the bottom-right lock room of horizontal elongated hole of angle locating slot 29
Territory is moved towards weakened region.
After transmission clutch block 8 deflection puts in place, the end of elastic on-of pin assembly 14 corresponds to described angle limit groove 27,
Angle alignment pin 28 moves into Part III from weakened region.Along with latch frame 1 motion puts in place, discharge manual unlocking push rod 5,
Manual unlocking frame 4 exists relative to latch frame 1 movement tendency to the left under the rebound effect of the first spring 6, elastic on-of pin
The end of assembly 14 is in effect long a small distance of end micro stretching of lozenges, and This move occurs in a short period of time, because of
This, the end of elastic on-of pin assembly 14 snaps in angle limit groove 27 just.Thus, the end of elastic on-of pin assembly 14
With the coordinating of angle limit groove 27, transmission clutch block 8 install axle 12 and axis hole 9 coordinate and angle alignment pin 28 and
The laterally supported at three point (as shown in Figure 7b) cooperatively formed along straight line of the Part III of elongated hole.In the situation without external force
Under, transmission clutch block 8 keeps this deflection angle, and its active force is possible to prevent owing to lock body shakes transmission clutch block 8 times
Turn.Now, transmission clutch block, latch frame and manual unlocking frame rest on right limit position.
When motor resume work band carry-over bar move right time, the trundle 18 of tooth bar enters the biography towards upper left side opening
Dynamic draw-in groove 10, and promote transmission clutch block 8 deflection to reset, owing to trundle 18 passes to transmission clutch block one under driven by motor
Fixed moment, therefore the second shank end of elastic on-of pin departs from from angle limit groove 27.Along with transmission clutch block 8
Deflection resets, and the opening of transmission draw-in groove 10 returns to the surface of transmission clutch block 8, and angle alignment pin 28 enters weakened region.By
There is ' locked ' zone on the right side of weakened region, lose stop on the right side of angle alignment pin 28, at this moment, manual unlocking frame 4 is at the first bullet
Being moved to the left a segment distance relative to transmission clutch block 8 and latch frame 1 under the compressing of spring, angle alignment pin 28 enters lock room
Territory, the most elastic on-of pin assembly protrudes the second surface of manual unlocking frame 4 under the effect of lozenges and stretches into transmission clutch
Lock slots 11 on the right side of block 8.So far, locking is recovered between tooth bar 2 and latch frame 1.Now, transmission clutch block, manual unlocking frame,
Latch frame and tooth bar are fixed, and are in right limit position together.
The driving method of bolt mechanism
Seeing Fig. 8-11, the driving method of the bolt mechanism of described manual clutch is as follows: uses one and drives dynamic control device,
Drive dynamic control device to include being respectively provided with lock-bit travel switch 39 and open position stroke along the two ends of the direction of motion of described latch frame 1
Switch 40, the position of described latch frame 1 monitored by described lock-bit travel switch 39, and described tooth bar monitored by described open position travel switch 40
The position of 2, described lock-bit travel switch 39 is connected with described panel 26 with described open position travel switch 40.Latch frame moves to
During locked position of coupler, lock-bit travel switch closes, and when tooth bar moves to lockset position of coupler, open position travel switch closes.
In normal operation, motor drives tooth bar 2 to move back and forth by gear 25 to smart electronics keeper, rack drives
Latch frame 1 realization of moving is unblanked and locking.Seeing Fig. 8, under lock open mode, lock-bit travel switch 39 disconnects, and open position stroke is opened
Closing 40 to be closed by tooth bar 2, panel receives cut-off signal and the closure signal of open position travel switch of lock-bit travel switch, this
Time, press on remote-control key when driving button, motor is failure to actuate；When pressing the pass button on remote-control key, panel controls electricity
Gear on machine rotates counterclockwise driving tooth bar and switches off to left movement, open position stroke, and rack drives latch frame is moved to the left,
In the fully-inserted snap close of lock pin, door is blocked, and lock-bit travel switch is closed by latch frame, and panel controls motor and quits work,
As shown in Figure 8.
Seeing Fig. 8, under blocking, open position travel switch 40 disconnects, and lock-bit travel switch 39 is closed by latch frame 1, control
