Adopt technique scheme, the utility model beneficial technical effects is: 1, by motor is controlled, motor whenever revolves through reducer output shaft transmission special shape gear and turns around, the special shape gear driving rack is done linear reciprocating motion once, lock shaft that the tooth bar front end is fixing and dead bolt cooperate to be finished pulling and discharges two actions, thus the unlatching of finishing an electric control door lock with reset.2,, thereby satisfied the big requirement of the required pulling force of this electric control door lock because reducer has reached the effect that rotating speed reduction, torque increase behind multi-stage speed-reducing.Adopt the structure of gear drive tooth bar to have big and balanced, that stroke the is big advantage of pulling force.3, the tooth bar configuration design becomes " L " shape, horizontal direction design section of rack, and vertical direction is the lock shaft pull portion structure, and has the lock shaft sliding function, motor rotates in the time of can avoiding artificially promoting dead bolt, wheel and rack is stuck and the accident generation of damage motor.4, the chute of tooth bar bottom processing is done rectilinear motion under motor cabinet pin guiding, need not the guide rail orientation, simplified part program.5, the shift fork that additional tapered end rotates is set, can need start the situation of electric control door lock with key under, uses again.6, a kind of typical design parameters is: tensile force f 〉=3.5kg; Stroke L 〉=10mm; Volume V99x98.5x35 (mm); Electric current 180mA (zero load); Electric current 2 450mA (load 〉=3.During 5kg).
In sum, the utility model is the electric control door lock that a kind of pulling force is big, stroke is big, volume is little, electric current is little.
Below by embodiment in detail, and its structure is described in detail in conjunction with the accompanying drawings:
Description of drawings
Fig. 1 is a kind of perspective view of electric control door lock.
Fig. 2 is that Fig. 1 electric control door lock is contained in the plane figure schematic diagram in the lock box.
Fig. 3 is " L " shape rack structure enlarged drawing in Fig. 1 electric control door lock.
The specific embodiment
In conjunction with Fig. 1 to Fig. 3, a kind of electric control door lock, comprise lock box 15, motor 5, motor cabinet 1, mechanical transmission mechanism and electronic switch 2, motor 5 is fixed on the motor cabinet 1, motor cabinet 1 and mechanical transmission mechanism are fixed in the lock box 15, mechanical transmission mechanism comprises reducer 4, special shape gear 12, tooth bar 3, lock shaft 10, spring 9, dead bolt 8, tie rod 6 and tapered end rotate shift fork 7, motor 5 is through reducer 4 deceleration transmission special shape gears 12, special shape gear 12 driving racks 3, the configuration design of tooth bar 3 becomes " L " shape, tooth bar 3 is slidably supported on the motor cabinet 1 by its bottom chute 11, correspondence is provided with guide pin (being blocked by tooth bar 3) in Fig. 1 on motor cabinet 1, tooth bar is done rectilinear motion by its bottom chute under motor cabinet pin guiding, the front end vertical component of tooth bar 3 has lock shaft hole 13, one end of lock shaft 10 passes lock shaft hole 13 and flexibly connects with latch 14 and tooth bar 3, be installed with spring 9 on the lock shaft 10, one end of spring 9 is fixed on the motor cabinet 1, the other end of lock shaft 10 is directly riveted dead bolt 8, on the motor cabinet 1 of tooth bar 3 rear ends, be fixed with electronic switch 2, electronic switch 2 will touch and discharge signal of telecommunication output control motor 5 rotations that produced behind the electronic switch or stop in tooth bar 3 motion processes, tie rod 6 one ends are fixedlyed connected with dead bolt 8, and the tapered end that the other end overlap joint of tie rod 6 is fixed on the lock box 15 rotates shift fork 7.
Present embodiment has selected that power is big, the higher micro machine of rotating speed for use, and at the output configuration reducer 4 of motor 5, reducer has reached the effect that rotating speed reduction, torque increase behind multi-stage speed-reducing, thereby has satisfied the big requirement of the required pulling force of this electric control door lock.
Design of gears adopts the special shape gear 12 of little modulus, minor diameter, and the number of effective actual teeth that gear uses is 1/3～1/2 of complete gear wheel.Motor reducer 4 terminal output shafts whenever revolve and turn around, and special shape gear obtains 1/3～1/2 circumference of gear stroke.When tooth on the special shape gear 12 and tooth bar 3 engagements, pulling tooth bar 3 (in Fig. 1 and Fig. 2, spring 9 compressions, dead bolt 8 is in the retracted state that pulling puts in place), tooth bar 3 passes through latch 14 pulling lock shafts, dead bolt to left movement; Tooth on special shape gear 12 rotates and finishes, and special shape gear 12 loses engagement with tooth bar 3, and tooth bar 3 is return motion to the right under the effect of spring force.Like this, motor reducer terminal output shaft revolve turn around in, special shape gear 12 cooperate with tooth bar 3, lock shaft 10, dead bolt 8 has finished the pulling and discharge two actions, thereby make electric control door lock realized the pulling and (stretching) function that resets.
Electric control door lock adopts and special shape gear 12 identical close-toothed tooth bars 3.The configuration design of tooth bar 3 becomes " L " shape, and tooth bar 3 has converted special shape gear 12 torque transmitted to pulling force.The front end vertical direction of tooth bar 3 has lock shaft hole 13, and an end of lock shaft 10 passes lock shaft hole 13 and flexibly connects with latch 14 and tooth bar 3.When artificial promotion dead bolt 8, lock shaft 10 moves simultaneously, and 3 of lock shaft 10 and tooth bars be slidingly matched for the gap, and tooth bar 3 can not move.Because, having the lock shaft sliding function, motor rotates in the time of can avoiding artificially promoting dead bolt, wheel and rack is stuck and the accident generation of damage motor.
The effect of tie rod 6 in the mechanical transmission mechanism of electric control door lock: start with key under the situation of electric control door lock at need, additional tapered end rotates shift fork 7 and stirs tie rod 6, and tie rod 6 drives dead bolts 8 and does straight reciprocating motion, the unlatching that realizes this lock with reset.Tie rod has limit function again, can prevent the stuck phenomenon that dead bolt produces because of artificial promotion.
The effect of electronic switch 2: electronic switch 2 with touch in tooth bar 3 motion processes and release-push after the signal of telecommunication that produced be used to control motor 5 and rotate and stop, thereby the unlatching of control electric control door lock and resetting.
During work, mechanical transmission mechanism drives special shape gear 12 with power output by reducer 6 by micro machine 5 and gives tooth bar 3 with transmission of torque, and tooth bar 3 becomes pulling force with the torque conversion that motor 5 produces, and tooth bar 3 drives lock shaft 10, and lock shaft 10 drives dead bolt 8 and does stretching motion.Mechanical transmission mechanism is done linear reciprocating motion under the driving of motor 5, special shape gear 12.The moving circle of motor reducer output shaft revolution, mechanical transmission mechanism is done linear reciprocating motion once, finishes the unlatching and the homing action of an electric control door lock.
