Shown in Fig. 1-6.
A kind of electric door lock tongue driving device; It comprises drive motors 24; The output shaft of described drive motors 24 links to each other with the power shaft of reduction box 3, and reduction box 3 is provided with two output shafts, and wherein first output shaft 20 links to each other with first driving shaft 7 through first drive unit of installing on it 25; Thereby first driving shaft 7 drives the locking and unlocking that locking centering block 6 is realized dead bolt relatively with one side of locking centering block 6, and the stopping step 5 on the another side of locking centering block 6 and the dead bolt 2 is relative; Second output shaft 9 of reduction box 3 links to each other with dead bolt 2 through second drive unit 26 and drives dead bolt 2 and in guiding mechanism 4, move; Described guiding mechanism 4 can adopt closed-in construction during practical implementation; Its width should be complementary with the targeting part of dead bolt 2 (being a square tongue among Fig. 1,2, is that example is explained with square tongue below).On the sidewall of housing 1, be provided with the opening that matches that the tongue body that supplies square tongue 2 partly passes in and out; Like Fig. 1, shown in 2; At least be formed with a stopping step 5 between described square of tongue 2 targeting part and the tongue body part; Described stopping step 5 one sides are equipped with locking centering block 6 (as shown in Figure 5), and this locking centering block 6 is journaled on the pivot and with an end of torsion spring and links to each other, and one side of locking centering block 6 is relative with stopping step 5.
During practical implementation; First drive unit 25 (as shown in Figure 6) can be made up of first driving spring 21 and first drive pin 22; Be set with support 19 on first output shaft 20; Support 19 links to each other with first driving shaft 7, and described first driving spring 21 is sleeved on first output shaft 20 and is arranged in support 19, and described first drive pin 22 is installed on first output shaft 20 and can from the screw thread of first driving spring 21, stretches out.
Second drive unit 26 (like Fig. 2) can be made up of second driving spring 8 and second drive pin 10; Described second driving spring 8 be sleeved on second output shaft 9 and same suit above that forward drive piece 11 and retreat between the drive block 12; Forward drive piece 11 with retreat drive block 12 and be fixed on the dead bolt 2, described second drive pin 10 is fixedly mounted on second output shaft 9 and between the screw thread of second driving spring 8, stretches out.
Reduction box 3 (encouraging shown in the section 7) can be made up of first gear 27, second duplicate gear 28, the 3rd duplicate gear 23, the 4th duplicate gear 29, the 5th duplicate gear 30, the 6th duplicate gear 31 and the 7th gear 13; First gear 27 is installed on the output shaft of drive motors 24; First gear 27 is meshed with gear wheel in second duplicate gear 28; Pinion in second duplicate gear 28 is meshed with gear wheel in the 3rd duplicate gear; The 3rd duplicate gear 23 is installed on first output shaft 20; Pinion in the 3rd duplicate gear 23 is meshed with gear wheel in the 4th duplicate gear 29, and the pinion in the 4th duplicate gear 29 is meshed with gear wheel in the 5th duplicate gear 30, and the 5th pair of pinion of hearing in the gear 29 is meshed with gear wheel in the 6th duplicate gear 31; Gear wheel in the 6th duplicate gear 31 is meshed with the 7th gear 13 simultaneously, and the 7th gear 13 is installed on second output shaft 9.
During practical implementation, in order to prevent in the Storage Cabinets of lateral, to carry out destructive picking lock, the present invention has designed pick-proof mechanism; Opposite side at square tongue 2 is provided with pick-proof step 14 for this reason; In a side of pick-proof step 14 locking clamp 15 locking clamps 15 are installed and are journaled on the clamp axle 16, torsion spring 17 is installed on the clamp axle 16, an end and the locking clamp 15 of torsion spring 17 offset; The other end and inner walls offset; One end of locking clamp 15 is relative with described pick-proof step 14, and the other end is wanted to be pressed on the pick-proof piece 18 on the housing base plate, like Fig. 1, shown in 3 under the effect of torsion spring 17.
The course of work of the present invention is:
Under lock-out state, after password or the fingerprint of input were correct, the reduction box motor action drove and subtracts the FCL motion; This moment little driving shaft at first move (can through the gear setting in the gear-box is realized) thus return and leave locking centering block 6, locking centering block 6 resets rapidly under the torsion spring effect, locking centering block 6 leaves stopping step 5; Return for square tongue 2 and to get ready, and then reduction box 3 drives driving shafts 9 and rotates, and the drive pin 10 on the driving shaft 9 rotates synchronously driving spring 8 drive block 12 1 ends of drawing back are promoted; Retreat drive block 12 driving shaft 9 right side motion in Fig. 2, also move right 2 withdrawals of square tongue thereby drive square tongue 2 in the elastic force effect lower edge of driving spring 8; Can carry out opening door operation, the step surface on square tongue 2 falls back on the position when moving right and offseting with guiding mechanism 4, and this moment, driving shaft 9 was rotated further; Driving spring 8 further compression keeps door opening state, and after the end of opening the door, sensor sensing is to needing at closing time; The counter-rotating of reduction box motor; This moment, driving shaft 9 elder generations moved, and after 2 releases of square tongue were put in place, little driving shaft 7 promoted locking goods of furniture for display rather than for use 6 again and is pressed on the stopping step place on square tongue 2.
When the people attempts to open housing bottom by force from the outside; The pick-proof piece 18 of housing bottom will at first damage; This moment, locking clamp 15 made square tongue to return on the stopping step that is pressed on square tongue 2 opposite sides under the effect of torsion spring 17 rapidly, thereby realized tamper-resistant function.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
