Dynamic bolt driving mechanism 32 is moved forward and backward, and realizes stretching out or retracting for dead bolt.As shown in Figure 1, Figure 2, the bolt driving mechanism 32 is wrapped
The tooth bar 322 of driving gear 321 and first is included, the driving gear 321 is fixed on lock core 20, in lock core 20 with key turns
When, driving gear 321 can be with lock core synchronous axial system.First tooth bar 322 is movably set in the inner surface of lock housing 10, and with institute
Driving gear 321 is stated to be meshed.Compartment of terrain is provided with the first push rod 3221 and the second push rod 3222 on the first tooth bar 322, and this
One push rod 3221 and the second push rod 3222 are actively placed through the first bar shaped slide opening 331 and the second bar shaped in dead bolt push pedal respectively
In slide opening 332, and can be moved in the first bar shaped slide opening and the second bar shaped slide opening so that when driving gear 321 is rotated with lock core
When, drive the first tooth bar 322 to move linearly by driving gear 321, and by its push rod 3222 of the first push rod 3221 and second
Dead bolt push pedal 33 is promoted to move forward and backward, so as to realize stretching out or retracting for dead bolt 31.
In order to suppress noise of the automatic door lock when locking a door, the present invention is provided with manual component 40, as shown in Figure 1 and Figure 2,
In the present embodiment, the manual component 40 includes rotating shaft 401, the second tooth bar 402, one-way clutch gear 403, one-way clutch
404 and manual part 405.The rotating shaft 401 is drive disk assembly, and its setting direction is perpendicular with the direction of dead bolt 31, and through lock
Manual component connecting hole 112 on shell is inside and outside lock housing.One end of the rotating shaft 401 actively through lock housing 10 and extends to door
External body, its end is connected with manual part 405.One-way clutch gear 403 and one-way clutch are equiped with the rotating shaft 401
404, the one-way clutch gear 403 and one-way clutch 404 can be known one-way clutch gear and one-way clutch, they
Can be roller-type overrunning clutch and one-way clutch gear, or free wheeling sprag clutch and one-way clutch gear.
In the present embodiment, one-way clutch gear 403 and one-way clutch 404 are Wolf-teeth one-way clutch and one-way clutch gear.Such as
Fig. 2, the one-way clutch gear 403 and one-way clutch 404 include outer race and rotationally connected inside race, one-way clutch
Gear 403 and one-way clutch 404 are coaxially installed in the rotating shaft 401, wherein, the inner seat of the one-way clutch 404
Circle is affixed with the rotating shaft 401, and the outer race of one-way clutch is affixed with lock housing 10.The inner seat of the one-way clutch gear 403
Circle is fixed in rotating shaft 401, and its outer race is then meshed with the second tooth bar 402.The rotating shaft 401 actively passes through lock housing 10 simultaneously
Extend to outside door body, its end is connected with manual part 405, the manual part can be known L-shaped door handle, by this
Manual part can control the speed that dead bolt when locking a door stretches out, and suppress automatic door lock by the speed for controlling dead bolt to stretch out and lock a door to make an uproar
Sound.
As shown in Figure 1, Figure 2, when door lock is opened, bolt driving mechanism 32 is driven to promote the tooth bar of dead bolt 31 and second by key
402 in lock housing 10 to moving, and the second tooth bar 402 promotes one-way clutch gear 403 to rotate in same direction, now, one-way clutch gear 403
Outer race separated with inside race, and the inside race of one-way clutch gear 403 and one-way clutch 404 is then fixed with rotating shaft 401
It is motionless.When the second tooth bar 402 is moved into place and dead bolt is fully retracted in lock housing, door lock is in opening.
When locking a door, the tooth bar 402 of dead bolt 31 and second is promoted or due to clutch component release by bolt driving mechanism 32
Drive dead bolt 31 to being moved outside lock housing 10, the outer race of one-way clutch gear 403 is promoted to direction outside lock housing from the second tooth bar 402
Rotate in same direction, now, outer race and the inside race of one-way clutch gear 403 are intermeshed, and drive the synchronous axial system of rotating shaft 401,
The inside race of one-way clutch 404 also with the synchronous axial system of rotating shaft 401.When the second tooth bar 402 is moved into place and dead bolt is fully extended
When outside to lock housing, door lock is in the lock state.Now, rotating shaft 401 can not be rotated backward, i.e., by rotating manual part 405 not
Door lock can be opened.In order to suppress noise of locking a door, in the second tooth bar 402 and dead bolt 31 are to moving process outside lock housing, can be to unidirectional
The direction of rotation of clutch gear 403 slower speeds rotating Vortex manual part 405, is controlled with will pass through the rotating speed of manual control rotating shaft
The speed that second tooth bar 402 and dead bolt 31 are displaced outwardly so that be can't hear in door lock surrounding environment during locking a door collision and
Grating, thus effectively inhibit the noise of locking a door of automatic door lock.
