Description
Technical Field
The invention belongs to the field of intelligent electronic locks, and particularly relates to a structure of an intelligent electronic lock capable of opening a latch bolt by using an outer door handle.
Background
The prior intelligent electronic lock, for example, application No. 201310143199.9, entitled "an electronic anti-theft lock body", discloses an electronic lock body that can be locked by a latch bolt when closing a door, can simultaneously unlock the latch bolt, the latch bolt and the dead bolt by an external handle, and can exchange the lock body between a left opening and a right opening only by replacing few parts, and comprises an external handle driving part, an external handle latch bolt pulling-out part, a rotating shaft part and a latch bolt hole arranged on the rotating shaft part; the outer handle driven piece is provided with an outer handle oblique tongue pulling back part, an outer handle square tongue pulling back part, an outer handle stiff tongue pulling back part and a shaft hole part. When the lock body of the type is locked, the dead bolt and the dead bolt are generally pulled out simultaneously, so that when the lock body enters the room from the outside, a clutch in the lock body is generally started through a verification unlocking instruction, and the dead bolt on the lock body can be withdrawn to open the door and enter the room through rotating the outer handle of the door. A smart lock body of this construction is obviously not particularly well-suited or friendly if used on an indoor door leaf and when the user is entering the room without wishing to perform cumbersome operations at ordinary times.
Disclosure of Invention
In light of the disclosure of the prior art, it is desirable and valuable to further improve the performance of existing smart locks and to further improve the structure of smart electronic locks, particularly their lock bodies. Therefore, aiming at the defects of the prior art, the invention provides an intelligent electronic lock structure, which comprises a door lock controller, an external door handle, an internal door handle and a lock body, wherein the lock body is provided with a square bolt and a latch bolt; the door lock further comprises a clutch and a clutch driver which are arranged in the lock body, wherein the clutch comprises an outer clutch block and an inner clutch block which are in clutch connection with each other, the door lock controller is used for receiving and verifying an unlocking instruction and then determining whether to start the clutch driver according to a verification result, and the clutch driver is used for driving the outer clutch block and the inner clutch block to be relatively disengaged or engaged; the clutch is characterized in that an outer latch bolt shifting fork capable of shifting the latch bolt to retract when the outer clutch block rotates in the forward direction is arranged on the outer clutch block, the inner handle is in transmission connection with the inner clutch block, the outer handle is in transmission connection with the outer clutch block, and the latch bolt is retracted through the outer latch bolt shifting fork on the outer clutch block when the outer handle rotates in the forward direction.
The door lock controller is a control center of the whole intelligent lock and is not only responsible for unlocking signal verification but also responsible for driving the actions of devices such as a clutch of the lock body.
The first one is to execute an unlocking command, namely, when the door lock controller verifies that the unlocking command is correct and drives the clutch to act, the square bolt and the latch bolt are retracted by rotating the door outer handle so as to open the door (unlock); and secondly, executing a locking instruction, namely directly lifting the door outer handle when a user wants to lock when the user goes out, so as to realize locking and closing.
The outer latch bolt shifting fork is a mechanism which is arranged on the outer clutch block and can directly or indirectly withdraw the latch bolt. In one embodiment, the outer latch bolt shift fork does not directly retract the latch bolt but retracts the latch bolt by rotating a latch bolt shift lever disposed within the lock body. The latch bolt shifting handle is a middle transmission component which is separated from the clutch and transmits the rotation torque of the outer latch bolt shifting fork to the latch bolt. In the lock body structure, the outer oblique tongue shifting fork cannot shift the oblique tongue or the square tongue in the reverse lifting motion direction of the door outer handle, and only shifts the oblique tongue shifting handle in the forward rotation direction of the door outer handle to withdraw the oblique tongue.
The forward rotation comprises a forward rotation action and a forward rotation direction, and refers to an action of rotating the door handle in a door opening direction; in practical applications, the door leaf includes left-opening door, right-opening door, etc., and the door leaves with different installation directions may have different door handle opening directions, either clockwise or counterclockwise, but the directions in which the door leaf can be opened are the forward rotation and forward rotation directions defined herein.
According to the technical scheme, the outer clutch block is provided with the outer oblique tongue shifting fork which can shift the oblique tongue to retract when rotating in the forward direction, so that the structure for retracting the oblique tongue outside a door is simple, too much space in the lock body is not occupied, and the structure of the lock body is simple; secondly, the latch bolt can be retracted by using the outer latch bolt shifting fork under any condition (no matter whether the clutch and the clutch driver act or not), so that when the intelligent door lock is used for an indoor door leaf, the intelligent door lock can only use the latch bolt to close the door under the condition that the latch bolt is retracted, and only the outer door handle or the inner door handle needs to be rotated to retract the latch bolt during entering and exiting, thereby being simple and convenient to operate. However, when the user wants to raise the security level of the door lock when going out and wants to dial out the dead bolt, the user only needs to lift the outer door handle reversely, and in this case, the unlocking instruction verification must be started when opening the door.
The technical scheme can also be that the outer clutch block is further provided with an outer square bolt shifting fork which can shift the square bolt to be locked when the outer door handle is lifted reversely, and the outer square bolt shifting fork on the outer clutch block can be shifted out of the square bolt to be locked when the outer door handle is lifted reversely. That is, the outer clutch block is provided with the outer latch bolt shifting fork as well as the outer latch bolt shifting fork, but the outer latch bolt shifting fork cannot trigger to withdraw the latch bolt when the outer door handle (the outer clutch block) is rotated, particularly in the forward direction (namely, no transmission relation is generated between the outer latch bolt shifting fork and the latch bolt or the latch bolt shifting handle). When the door outer handle is lifted reversely, the dead bolt can be pulled out through the outer dead bolt shifting fork on the outer clutch block to achieve the purpose of locking (at the moment, the dead bolt keeps the automatic extending state).
Wherein, the reverse direction refers to the direction and action opposite to the forward rotation. The outer square tongue shifting fork can be directly shifted out of the square tongue to be locked, and can also be indirectly shifted out of the square tongue through a middle transition shifting fork to be locked.
The inner clutch block is also provided with an inner square tongue locking shifting fork which can shift the square tongue to be locked when the inner door handle is lifted reversely, and the square tongue can be shifted out and locked by the inner square tongue locking shifting fork on the inner clutch block when the inner door handle is lifted reversely; the inner square bolt unlocking shifting fork capable of shifting the square bolt and the oblique bolt to be simultaneously withdrawn when the door inner handle is rotated in the forward direction is further arranged, and the square bolt and the oblique bolt can be withdrawn through the inner square bolt unlocking shifting fork on the inner clutch block to be unlocked when the door inner handle is rotated in the forward direction. Namely, the inner clutch block is provided with not only the inner square bolt locking shifting fork but also the inner square bolt unlocking shifting fork, and the inner square bolt locking shifting fork and the inner square bolt unlocking shifting fork respectively play different roles when the inner clutch block rotates forwards or backwards.
The technical scheme can also be that the door lock controller is also used for starting the clutch driver after receiving and verifying an unlocking instruction and verifying that the result belongs to a legal unlocking instruction; the clutch driver is used for driving the outer clutch block and the inner clutch block to perform involutory action so that the square bolt and the latch bolt can be withdrawn through the outer clutch block and the inner clutch block to unlock when the door outer handle is rotated in the forward direction. At the moment, the door outer handle is rotated in the positive direction, the door outer handle also retracts the latch bolt through the outer latch bolt shifting fork on the outer clutch block, and the door outer handle and the outer clutch block play a role in retracting the latch bolt in parallel. Therefore, when the intelligent door lock is used for an indoor door leaf and when a user wants to improve the safety level of the door lock when going out, the user needs to start an unlocking instruction to verify unlocking.
The further technical scheme can also be that after the lock body retracts the dead bolt, when the door outer handle is in a natural state, the inclined bolt of the lock body also keeps an automatic extending state.
The invention has the characteristics and advantages, so the invention can be applied to the intelligent electronic lock structure.

The structure of the intelligent electronic lock to which the present invention is applied will be further described with reference to fig. 1 to 3.
The invention provides an intelligent electronic lock structure, as shown in fig. 1 to fig. 3, the intelligent electronic lock is installed on a door leaf 100, wherein the intelligent electronic lock comprises an outer panel 11 installed on the outer side surface of the door leaf 100, an outer door handle 1 installed on the outer panel 11, an inner panel 21 installed on the inner side surface of the door leaf 100, an outer door handle 2 installed on the inner panel 21, and a lock body 3 installed in the door leaf 100. And a door lock controller (not shown) installed in the outer panel 11 or the inner panel 21. The door lock controller is a control center of the whole intelligent lock and is not only responsible for unlocking signal verification but also responsible for driving the actions of the clutch 33 and other devices of the lock body 3.
The lock body 3 is provided with a dead bolt assembly 31, a latch bolt assembly 32, a lower cover plate assembly 35, a lock body side plate 36 and an upper cover plate (not shown in the figure), the dead bolt assembly 31 is provided with a dead bolt 311, and the latch bolt assembly 32 is provided with a latch bolt 320, a latch bolt connecting rod 321, a latch bolt return spring 322 and a signal switch 323. The latch bolt return spring 322 is sleeved on the latch bolt connecting rod 321 to drive the latch bolt 320 to automatically return and extend, and the signal switch 323 is abutted against the latch bolt connecting rod 321 to pick up moving signals of the latch bolt connecting rod 321 and the latch bolt 320 and is in signal connection with the door lock controller. The square tongue 311 is used to lock and lock the door 100, and the latch tongue 320 is used to temporarily close (cover) the door 100, which is commonly referred to as a wind-proof tongue. The door handle 1 is used for executing an unlocking or locking command outside the door leaf 100, and the latch 320 of the lock body 3 is also kept in an automatically extended state when the door handle 1 is in a natural state. A clutch 33 and a clutch driver 34 are further arranged in the lock body 3, the clutch 33 comprises an outer clutch block 331 and an inner clutch block 332 which are in clutch connection with each other, the door lock controller is used for receiving and verifying an unlocking instruction and then determining whether to start the clutch driver 34 according to a verification result, and the clutch driver 34 is used for driving the outer clutch block 331 and the inner clutch block 332 to be relatively disengaged or engaged; the outer clutch block 331 is provided with an outer latch bolt shifting fork 4 which can shift the latch bolt 320 to be retracted when rotating in the forward direction, the inner handle 2 is in transmission connection with the inner clutch block 332, the outer handle 1 is in transmission connection with the outer clutch block 331, and the latch bolt 320 is retracted through the outer latch bolt shifting fork 4 and the latch bolt shifting handle 5 on the outer clutch block 331 when the outer handle 1 is rotating in the forward direction. Wherein the outer latch fork 4 is a mechanism provided on the outer clutch block 331 capable of directly or indirectly retracting the latch 320. In this embodiment, the outer latch bolt shifter 4 does not directly receive back the latch bolt 320 but retracts the latch bolt 320 by rotating the latch bolt shifter handle 5 disposed in the lock body 3. The latch bolt shifting handle 5 is a component which is separated from the clutch 33 and transmits the rotation torque of the outer latch bolt shifting fork 4 to the middle transmission of the latch bolt connecting rod 321 of the latch bolt 320. In the structure of the lock body 3, the outer latch bolt shifting fork 4 cannot shift the latch bolt 320 or the dead bolt 311 in the reverse lifting motion direction of the door outer handle 1, and only shifts the latch bolt connecting rod 321 in the forward rotation direction of the door outer handle 1 to withdraw the latch bolt 320.
The door handle further comprises an outer handle square iron 61 connected with the door outer handle 1 and an inner handle square iron 62 connected with the inner handle 2, one end of the outer handle square iron 61 is inserted into the outer clutch block 331 so as to transmit the rotating torque of the door outer handle 1, and one end of the inner handle square iron 62 is inserted into the inner clutch block 332 so as to transmit the rotating torque of the door inner handle 2. The door external handle 1 is used for executing an unlocking or locking command outside a door, and comprises two aspects, namely, executing an unlocking command, namely, when the door lock controller verifies that an unlocking command is correct and drives the clutch 33 to act, rotating the door external handle 1 to withdraw the square bolt 311 and the latch bolt 320 so as to open the door (unlocking); the second is to execute a locking command, that is, when the user goes out, the user directly backs up the outer door handle 1 when wishing to lock, thereby locking and closing the door.
According to the technical scheme, the outer clutch block 331 has the beneficial technical effects that firstly, the outer latch bolt shifting fork 4 capable of shifting the latch bolt 320 to retract when rotating in the forward direction is arranged on the outer clutch block 331, so that the structure for retracting the latch bolt 320 outside a door is simple, and too much space in the lock body 3 is not occupied, so that the structure of the lock body 3 is simple; secondly, the latch bolt 320 can be retracted by using the outer latch bolt fork 4 under any condition (i.e. whether the clutch 33 and the clutch actuator 34 are actuated or not), so that when the intelligent door lock is used for an indoor door leaf, the door can be closed only by using the latch bolt 320 under the condition that the latch bolt 311 is retracted, and only the outer door handle 1 or the inner door handle 2 needs to be rotated to retract the latch bolt 320 during entering and exiting, thereby facilitating the operation. However, when the user wants to raise the security level of locking the door when going out and wants to dial out the square bolt 311, he only needs to lift the outer door handle 1 back, and in this case, the user must start the verification of the unlocking instruction when opening the door.
Further, according to the technical scheme, the outer clutch block 331 is further provided with an outer bolt shifting fork 3311 which can shift the bolt 311 to be locked when the door outer handle 1 is lifted reversely, and the bolt 311 can be shifted out by the outer bolt shifting fork 3311 on the outer clutch block 331 to be locked when the door outer handle 1 is lifted reversely. That is, the outer clutch block 331 is provided with the outer latch yoke 4 and the outer latch yoke 3311, but the outer latch yoke 3311 cannot trigger retraction of the latch 320 when the door outer handle 1 (the outer clutch block 331) is rotated, particularly, in the forward direction (i.e., no transmission relationship is generated between the outer latch yoke 3311 and the latch 320 or the latch lever 5). When the door outer handle 1 is lifted, the dead bolt 311 can be pulled out by the outer dead bolt shift fork 3311 on the outer clutch block 331 to achieve the purpose of locking (at this time, the latch bolt 320 keeps the automatic extending state).
Further, according to the technical scheme, the inner clutch block 332 is further provided with an inner latch locking shift fork 3321 which can shift the latch bolt 311 to be locked when the inner door handle 2 is lifted reversely, and the latch bolt 311 can be shifted out to be locked by the inner latch locking shift fork 3321 on the inner clutch block 332 when the inner door handle 2 is lifted reversely; an inner square tongue unlocking shifting fork 3322 which can shift the square tongue 311 and the oblique tongue 320 to be simultaneously withdrawn when the door inner handle 2 is rotated in the forward direction is further arranged, and the square tongue 311 and the oblique tongue 320 can be withdrawn through the inner square tongue unlocking shifting fork 3322 on the inner clutch block 332 to be unlocked when the door inner handle 2 is rotated in the forward direction. That is, the inner clutch block 332 is provided with not only the inner-tongue locking shift fork 3321 but also the inner-tongue unlocking shift fork 3322, and the inner-tongue locking shift fork 3321 and the inner-tongue unlocking shift fork 3322 respectively exert different functions when the inner clutch block 332 rotates in the forward direction or in the reverse direction.
The further technical scheme can also be that the door lock controller is also used for starting the clutch driver 34 after receiving and verifying an unlocking instruction and verifying that the result belongs to a legal unlocking instruction; the clutch driver 34 is used for driving the outer clutch block 331 and the inner clutch block 332 to perform a relative motion so that the latch 311 and the latch 320 can be retracted to unlock the door handle 1 by the outer clutch block 331 and the inner clutch block 332 when the door handle 1 is rotated in a forward direction. At this time, the door outer handle 1 retracts the latch bolt 320 by the outer latch bolt shifter 4 of the outer clutch block 331 due to the forward rotation of the door outer handle 1, and both of them perform the function of retracting the latch bolt 320 in parallel. For this reason, when the intelligent door lock is used for an indoor door leaf and when a user wants to raise the security level of the locked door when going out, the user needs to activate an unlocking command to verify unlocking.
Further, according to a further technical solution, after the lock body 3 retracts the dead bolt 311, when the door handle 1 is in a natural state, the latch bolt 320 of the lock body 3 also maintains an automatically extended state.
