Technical Field

The invention relates to the technical field of locks, in particular to an idle-run lock head and an intelligent lock with the same.

Background

For a common mechanical safety lock, the simplest way to upgrade the safety lock into an intelligent lock without replacing the door lock in the door leaf is to replace only the lock head and the handle. The upgrading mode is economical, convenient and fast. However, this requires that all of the smart components be located in the lock and handle. Because of the limitation of the original door lock structure, the structure scale of the lock head is difficult to change greatly, and therefore, the space for arranging the intelligent components is mainly arranged in the handle. And because the information acquisition module of modes such as fingerprint, iris, facial recognition and password input among the intelligent components and parts must be set up in the outer handle, therefore it is the simplest mode to set up all intelligent components and parts in the outer handle. However, the disadvantage of this arrangement is that the outer handle is most vulnerable to damage, and once the outer handle is damaged, the door lock can be unlocked directly by using the electric driving mechanism, bypassing the information acquisition and identification module.

The mode of solving the problem is to arrange all other intelligent components except the information acquisition module in the inner handle and connect the intelligent elements in the inner and outer handles through a signal wire passing through the lock head. However, conventional inner and outer handles do not always rotate together during operation. For example, chinese patent document CN102704755A discloses a double-transmission unlocked cylinder type idling lock head, which includes a lock body (i.e. a lock sleeve), an unlocking member (i.e. a thumb wheel) rotatably mounted on the lock sleeve, a rotating member (i.e. a lock core) rotatably mounted in the lock sleeve outside the thumb wheel and mainly composed of an inner lock core (i.e. an idling core) and an unlocking core (i.e. a locking core), wherein a clutch assembly is disposed between the locking core and the thumb wheel, a transmission core fixedly connected to an inner handle is rotatably mounted in the lock sleeve inside the thumb wheel, and the transmission core is fixedly connected to the thumb wheel. When the matched key is inserted into the idle core, the idle core is linked with the locking core, and the key pushes the clutch component, so that the locking core drives the shifting wheel to rotate through the clutch component, and the lock head is opened. In the prior art, the lock cylinder and the transmission cylinder respectively occupy two sides of the thumb wheel, and the lock head can be unlocked by the inner handle without a key, so that the lock cylinder and the transmission cylinder cannot synchronously rotate. Particularly, when the idle lock head in the prior art is unlocked without a key, the idle core can idle relative to the lock sleeve, the lock core is kept fixed relative to the lock sleeve, and meanwhile, the clutch mechanism needs to be kept fixed circumferentially relative to the lock core, so that the problem that a communication signal wire connecting the information acquisition module and other intelligent components is often wound in work can be caused. In addition, this prior art needs to set up the lock core fixture block and starts the core and leads to its structure complicacy.

Therefore, the lock core structure (i.e. the lock head) of the intelligent door lock disclosed in chinese patent document CN109025531A includes an outer handle assembly and an inner handle assembly, an information acquisition module is installed in the outer handle assembly, the inner handle assembly includes a first rotating part installed with a control module and a second rotating part sleeved outside the first rotating part, and the information acquisition module receives and acquires and sends user information to the control module; a first tubular shaft has one end connected to the outer handle assembly and the other end connected to the first rotatable member. The control module is electrically connected with the information acquisition module through a lead (namely a signal wire) which passes through the lumen of the first rotating shaft; the thumb wheel is fixed with a second rotating shaft (namely a rotating shaft), the rotating shaft is sleeved on the part of the first rotating shaft extending to the inner handle assembly, one end of the rotating shaft close to the inner handle is connected with a second rotating part, and the thumb wheel rotates relative to the shaft shell (namely a lock sleeve) to realize unlocking or locking; a clutch structure controlled by the control module is arranged between the first rotating shaft and the thumb wheel. Under the condition that the clutch structure is not in transmission connection, the inner handle assembly is rotated to drive the shifting wheel to rotate so as to complete unlocking driving; when the control module receives unlocking information which is sent by the information acquisition module and is matched with the preset information, the clutch structure is controlled to realize transmission connection, the outer handle is rotated to drive the first rotating shaft, the first rotating part and the second rotating part, and then the shifting wheel is driven to rotate to complete unlocking driving. The lock head in the prior art can avoid the problem that the wire is twisted and cracked. However, the lock cylinder of the prior art is provided with the first rotating shaft with the pipe cavity, so that the pipe cavity arranged on the first rotating shaft occupies the position where the key hole is usually arranged, and the lock cylinder is not suitable for increasing the key opening function because the arrangement of the pipe cavity makes the arrangement between the outer lock sleeve and the first rotating shaft occupying the position of the lock cylinder unsuitable for arranging the key mechanism suitable for key opening. Therefore, once one of the electronic components such as intelligent identification, signal transmission or control module has a problem and the lock head can not be opened in an intelligent mode, the door leaf is difficult to open without breaking.

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

In one embodiment of the idle-rotation lock head shown in fig. 1-2, the idle-rotation lock head 3 has a main lock sleeve 34 formed with a through cavity, a main lock cylinder 31 rotatably disposed in the through cavity, an unlocking member disposed coaxially with the main lock cylinder 31, and a manual unlocking clutch mechanism disposed between the main lock cylinder 31 and the unlocking member for controlling the transmission connection therebetween.

The primary lock sleeve 34 is composed of an inner lock sleeve body, an outer lock sleeve body, and a coupling beam connecting the inner lock sleeve body and the outer lock sleeve body. A notch is formed between the inner and outer lock cylinder bodies of the main lock cylinder 34, and the through cavity is divided into an inner part and an outer part by the notch, wherein the outer part is a main cylinder cavity and the inner part is a transmission cavity, and the main cylinder 31 is rotatably arranged in the main cylinder cavity. The unlocking piece is used for driving a bolt mechanism of the door lock to open the door lock, and comprises a transmission core and a shifting wheel 32, wherein the transmission core is sleeved outside the main lock core 31 and is fixedly connected with the transmission core relatively, and the transmission core is rotatably arranged in the transmission cavity. The transmission core and the dial wheel 32 are both hollow tubular structures, and the main lock core 31 extends through an inner cavity of the hollow tubular structures and is in sliding fit with the inner cavity circumferentially.

The manual unlocking clutch mechanism is provided with a main secret key assembly and a clutch piece. The master key assembly is composed of a plurality of key member installation cavities formed in an axial direction on the master cylinder 31, a plurality of key members with unlocking openings provided in the respective key member installation cavities for reciprocal movement, and springs as biasing members for applying a biasing force to the key members so as to tend to a locked state. The key piece installation cavity is a page slot, and the key piece is a key page which is arranged in the page slot in a sliding manner; the moving direction of the key piece in the key piece installation cavity and the axial direction of the main lock cylinder 31 are perpendicular to each other.

The clutch member is a locking key 33 which is radially slidably disposed in a sleeve key groove formed in the through cavity of the main lock sleeve 34, and the locking key 33 axially corresponds to the main lock cylinder 31 and the unlocking member and is biased radially inward. The clutch piece and the unlocking piece are provided with mutually matched embedded clutch structures. The engaging and disengaging structure on the unlocking member is a disengaging and disengaging groove 322 which is formed opposite to the locking key 33 in a locking state; in the locked state, the key sheet is biased by the biasing member so that the unlocking notches are displaced from each other, and the locking key 33 is held in a disengaged position in which it is completely inserted into the key receiving groove; when an adaptive key is inserted into a key hole of the main lock cylinder 31 to be matched with a key structure of the key blades, the key blades are driven to move by overcoming the biasing force applied to the key blades, the unlocking openings on each key blade are arranged into a groove shape, the locking key 33 completely slides out of the key groove under the action of the biasing force towards the main lock cylinder 31 and enters the groove shape formed by the unlocking openings and the disengaging groove 322, namely, the locking key 33 moves from the disengaging position to the connecting position for connecting the main lock cylinder 31 with the unlocking piece in a transmission way, so that the transmission connection between the main lock cylinder 31 and the unlocking piece is realized.

The means for applying a biasing force to the locking key 33 includes at least two biasing member mounting holes formed in the primary lock sleeve 34 corresponding to the sleeve key slots and communicating with the sleeve key slots, and a key biasing means disposed in the biasing member mounting holes. At least two biasing member mounting holes are sequentially distributed along the axial direction of the main lock sleeve 34. The key biasing mechanism includes a steel ball 41 provided in the biasing member mounting hole near the sleeve key groove, and a pressure spring 42 provided between the main lock sleeve 34 and the steel ball 41, which applies a biasing force to the steel ball 41 toward the lock key 33. The outer lock sleeve body is provided with a connecting screw, the inner lock sleeve body and the outer lock sleeve body are fixed on the connecting beam through the connecting screw penetrating through the connecting beam, and the pressure spring 42 acts between the steel ball 41 and the connecting screw.

The clutch member also has a return mechanism that returns to a disengaged position after the key fob is removed. The reset mechanism is constituted by a mating slope between the unlock port and the lock key 33.

In another embodiment of the manual unlocking clutch mechanism shown in fig. 3-5, the key member mounting cavity is a pin hole, the key member is a pin 51 slidably disposed in the pin hole, the clutch member is a linking slide key 52 axially slidably disposed in an axially extending telescopic sliding slot formed in the main lock cylinder 31, and a plurality of convex teeth 53 respectively embedded between columns of the pin are formed on one side of the linking slide key 52 facing the pin 51. The key structure comprises an unlocking pin 54 arranged on the pin 51, the unlocking port 55 and the unlocking pin 54 are respectively arranged on two opposite sides of the pin 51, and the pin 51 is arranged on the main lock cylinder 31 with the unlocking pin 54 facing a key hole.

In the locked state, the pins 51 are biased by the biasing member so that the unlocking ports 55 are displaced from each other, and the interlocking slide 52 is held in the disengaged position by the teeth 53 embedded between the columns of the pins 51 and cannot slide in the axial direction of the master cylinder 31, and the unlocking pins 54 of the pins 51 are aligned; when an adaptive key is inserted into a key hole of the main lock cylinder 31, the pins 51 are driven by a key structure to move against the applied biasing force, so that the unlocking openings 55 on each pin 51 are arranged in a groove shape suitable for the convex teeth 53 on the linkage sliding key 52 to slide in, and the linkage sliding key 52 slides to the connection position where the embedded clutch structure is matched and connected under the action of the pushing force applied by the adaptive key to the unlocking piece, so that the transmission connection between the main lock cylinder 31 and the unlocking piece is realized.

The engaging and disengaging structure includes an engaging portion 56 of the engaging sliding key 52 extending toward the locking member at an end close to the locking member, and an engaging groove 322 formed on the locking member to face the engaging portion 56. A bent part 57 is extended from one end of the linkage sliding key 52 close to the unlocking part towards the key hole of the main lock cylinder 31, after the bent part 57 receives the pushing force applied by the inner end of the adaptive key, the linkage sliding key 52 moves along the groove shape to the direction of the thumb wheel 32, and the linkage part 56 is embedded with the clutch groove 322 to form transmission connection. After the key is removed, the link slide key 52 is slidably restored by a biasing spring 58 provided between the link slide key 52 and the master cylinder 31 as the restoring mechanism, and each pin 51 is also restored by a biasing force.

One embodiment of the intelligent lock as shown in 1, 2, 6 and 7 comprises the idle lock head 3, an outer handle assembly 1 installed outside the idle lock head 3, and an inner handle assembly 2 installed inside the idle lock head 3. The outer handle assembly 1 is fixedly connected with the outer end of the main lock cylinder 31 in a detachable mode, and an information acquisition module is arranged on the outer handle assembly 1. The unlocking piece is provided with a through hole, the main lock cylinder 31 penetrates through the through hole and extends to the position of the inner handle assembly 2, the inner end of the main lock cylinder 31 and the inner handle assembly 2 are provided with an inner handle shell which is detachably connected with the unlocking piece in a transmission mode and an inner handle inner core assembly 22 which is arranged in the inner handle shell and is detachably and fixedly connected with the inner end of the main lock cylinder 31, and the inner handle inner core assembly 22 comprises at least part of other intelligent components except the information acquisition module. The main lock cylinder 31 is provided with a threading channel allowing a signal wire for communicating the information acquisition module with at least part of other intelligent components to penetrate through.

The inner handle shell comprises an inner main shell 24 and an inner handle cover 21 fixedly arranged on one side of the inner main shell 24 close to the idle locking head 3. A handle shell inserting non-circular connecting structure 211 is formed at the end part of the inner handle shell, which is connected with the transmission core, and a thumb wheel inserting non-circular connecting structure 321 is correspondingly formed at the connecting end part opposite to the transmission core, so that the inner handle shell and the transmission core are fixed with each other in the circumferential direction after being inserted with each other. An inner handle locking mechanism is further arranged in the inner handle shell, and the inner handle assembly 2 and the idle lock head 3 are kept fixed in the inserting direction in the locking state of the inner handle locking mechanism; while maintaining the relative movement between the inner handle assembly 2 and the idle locking head 3 in the plugging direction in the unlocked state of the inner handle locking mechanism.

An intelligent unlocking clutch mechanism which is controlled by at least part of other intelligent components to be clutched is arranged between the inner handle inner core assembly 22 and the inner handle shell. As shown in fig. 10 and 11, the intelligent unlocking clutch mechanism includes a clutch slot 219 formed on the inner handle cover 21 of the inner handle shell and a clutch pin 223 movably disposed on the inner handle core assembly 22, and after the information of the information acquisition module is successfully compared with the information pre-stored in the control module, the electric unit drives the clutch pin 223 to be embedded into the clutch slot 219, so that the outer handle assembly 1 is in transmission connection with the inner handle shell.

As shown in fig. 6, non-circular connecting structures suitable for being inserted into each other are formed at the connecting end portions of the outer handle assembly 1, the inner handle assembly 2 and the idle lock head, and the connecting end portions are correspondingly connected with the main lock cylinder 31, and the outer handle assembly 1 and the inner handle assembly 2 drive the main lock cylinder 31 to rotate together through the non-circular connecting structures. An outer handle electrical connection terminal electrically connected with the information acquisition module is arranged at the connection end part of the outer handle assembly 1, and an outer door electrical connection terminal correspondingly connected with the outer handle electrical connection terminal is arranged at the outer end of the main lock cylinder 31 adjacent to the outer handle assembly 1; the connection end part of the inner handle assembly 2 is provided with an inner handle electric connection terminal 222 electrically connected with at least part of other intelligent components, and the inner end of the main lock cylinder 31 adjacent to the inner handle assembly 2 is provided with an inner door connection terminal 312 correspondingly connected with the inner handle electric connection terminal 222.

As shown in fig. 6, a shank plug non-circular connecting structure 221 and an inner shank electrical connecting terminal 222 which are fixedly and electrically connected with each other are formed on the end portion of the inner handle core assembly 22 which is connected with the main lock cylinder 31, and correspondingly, a lock cylinder plug non-circular connecting structure 313 which is matched with the shank plug non-circular connecting structure 221 and an inner door connecting terminal 312 which is correspondingly connected with the inner shank electrical connecting terminal 222 are formed on the end of the main lock cylinder 31 which is adjacent to the inner handle assembly 2. So that the inner handle core assembly 22 and the main lock cylinder 31 are fixed to each other in the circumferential direction after being inserted into each other, and simultaneously, the inner handle electrical connection terminal 222 and the inner handle core assembly 22 rotate relative to the inner handle shell synchronously.

In use, as shown in fig. 6, the inner handle assembly 2 is inserted into the non-circular connecting structure 321 of the driving core through the non-circular connecting structure 211, so that the inner handle shell and the driving core are fixed to each other in the circumferential direction after being inserted into each other. Meanwhile, the handle core insertion non-circular connecting structure 221 and the inner handle electrical connecting terminal 222 which are relatively fixedly and electrically connected are formed on the inner handle core assembly 22, and the lock core insertion non-circular connecting structure 313 and the inner door connecting terminal 312 which are arranged at one end, adjacent to the inner handle assembly 2, of the main lock core 31 are mutually matched to complete insertion connection, so that the inner handle core assembly 22 and the main lock core 31 are mutually inserted and then are circumferentially fixed to each other, and the inner handle electrical connecting terminal 222 and the inner handle core assembly 22 synchronously rotate relative to the inner handle shell.

A locking one-way clutch mechanism is also provided between the inner handle core assembly 22 and the inner handle shell. As shown in fig. 7 to 9, the uplock one-way clutch mechanism includes a stopper 225 fixedly provided on the inner handle core assembly 22 and a one-way stopper claw 214 pivotally mounted on the inner side of the inner handle cover 21 of the inner handle case by a pawl shaft 215, and a pawl spring 216 that applies a biasing force to the one-way stopper claw 214 so that an engaging end thereof engages with the stopper 225. The pawl shaft 215 is provided in the inner handle case on the side close to the idle lock head 3 and perpendicular to the rotational axis of the inner handle case, and a mounting hole for the pawl spring 216 is formed in the end wall of the inner handle cover 21 of the inner handle case facing the idle lock head 3, and a mounting screw 218 is threadedly fixed in the mounting hole so that the pawl spring 216 in the mounting hole exerts a biasing force on the one-way restriction pawl 214. Further, a central portion of the one-way stopper 214 is pivotally connected to the pawl shaft 215 such that both ends of the one-way stopper 214 respectively form an engaging end, and correspondingly, a mounting hole for the pawl spring 216 is formed in the end wall of the inner handle case facing the idle lock cylinder 3 corresponding to each of the engaging ends, and one of the pawl springs 216 is mounted in one of the mounting holes by the mounting screw 218 as required in the right and left door opening direction.

Before the inner handle assembly 2 is mounted to the idle lock cylinder 3, the pawl spring 216 is installed in the corresponding biasing member mounting hole according to the door leaf opening direction and fixed by the mounting screw 218 such that the corresponding side of the one-way clutch 214 is tilted by the biasing force of the pawl spring 216. After the inner handle assembly 2 is mounted on the idle lock head 3, the outer handle assembly 1 is rotated towards the unlocking direction in any state, and the main lock cylinder 31 fixedly connected with the outer handle assembly 1 can still rotate due to the idle lock cylinder structure, and meanwhile, the inner handle inner core assembly 22 fixedly connected with the main lock cylinder 31 in the circumferential direction is driven to rotate together. The stopper 225 fixedly disposed on the inner handle core assembly 22 is now moved from left to right in fig. 9, causing the pawl spring 216 exerting a biasing force on the one-way clutch 214 to be compressed and thus pass over the stopper 225 when the stopper 225 slides over the inclined surface of the one-way clutch 214. At this time, since there is no rotational connection between the main lock cylinder 31 and the thumb wheel 32, the thumb wheel 32 will not rotate in the unlocking direction with the rotation of the main lock cylinder 31 to drive the latch mechanism in the door lock to move in the locking direction. When the outer handle assembly 1 is rotated in the locking direction in the unlocking state, the stopper 225 on the inner handle core assembly 22 moves from the right side to the left side in fig. 8, and when meeting the straight edge of the one-way limiting claw 214, a transmission connection in the circumferential direction is established, so that the inner handle shell and the transmission core, which is circumferentially and non-rotatably inserted with the inner handle cover 21 in the inner handle shell, are driven to rotate together, and thus the thumb wheel 32 fixedly connected with the transmission core rotates in the locking direction along with the rotation of the transmission core to drive the latch mechanism in the door lock to move in the locking direction, and the locking process is completed. When it is desired to change the door opening direction, the pawl spring 216 and the mounting screw 218 can be replaced in the biasing member mounting hole corresponding to the other end of the one-way clutch 214 (i.e., as shown in fig. 12 and 13).

As shown in fig. 7, a cover bearing seat 212 is formed on the inner handle cover 21, a core bearing seat 224 is correspondingly formed on the inner handle core assembly 22, and a bearing 23 is installed between the cover bearing seat 212 and the core bearing seat 224. While a gap is maintained between the inner main shell 24 and the inner handle core assembly 22 so that the inner handle shell and the inner handle core assembly 22 are rotatably connected by the bearing 23. Specifically, the outer diameter of the bearing 23 is fitted into the spindle bearing seat 224 provided on the inner handle core assembly 22, and the inner diameter of the bearing 23 is fitted into the cover bearing seat 212 provided on the inner handle cover 21.

In the locked state, when the intelligent unlocking is adopted, firstly, the information acquisition module on the outer handle assembly 1 acquires relevant information, and the information is transmitted to the control module in the inner handle assembly 2 through a signal wire in a threading channel arranged on the main lock cylinder 31. As shown in fig. 10 and 11, when the collected information is successfully compared with the information pre-stored in the control module, the electric unit, such as an electromagnetic starting mechanism or an electric motor, is started to drive the clutch pin 223 disposed on the inner handle core assembly 22 to move, and the clutch slot 219 embedded and formed on the inner handle cover 21 of the inner handle shell, so that the main lock cylinder 31 is drivingly connected with the inner handle shell through the circumferentially fixed inner handle core assembly 22 via the intelligent unlocking clutch mechanism formed by the clutch pin 223 and the clutch slot 219. At this time, the outer handle assembly 1 is rotated in the unlocking direction to drive the inner handle shell to rotate together, the transmission core which is circumferentially and non-rotatably inserted with the inner handle cover 21 in the inner handle shell drives the thumb wheel 32 fixedly connected with the transmission core to rotate, and the rotation in the unlocking direction drives the latch mechanism in the door lock to move in the locking direction, so that the unlocking process is completed.

In the locked state, once the smart component fails, when the lock is mechanically unlocked by using the key adaptor, as shown in the embodiment of fig. 2, the key adaptor is inserted into the key hole of the main lock cylinder 31, the key adaptor drives each key blade in the main key assembly to overcome the biasing force applied to drive each key blade to move, the main key assembly on the main lock cylinder 31 is unlocked, and the locking key 33 completely slides out of the key slot of the main lock sleeve 34, and simultaneously one end of the locking key 33 is clamped into the engaging and disengaging slot 322 formed on the thumb wheel 32, so that the main lock cylinder 31 and the thumb wheel 32 form a transmission connection and rotate synchronously in the circumferential direction. That is, the rotation of the adaptive key can drive the dial wheel 32 to rotate, and rotate towards the unlocking direction to drive the latch mechanism in the door lock to move towards the locking direction, thereby completing the unlocking process.

Alternatively, the mounting positions of the stopper 225 and the one-way spacing pawl 214 pivotally mounted by the pawl shaft 215 may be interchanged.

As an alternative embodiment, the locking one-way clutch mechanism may employ a sprag type clutch or a ball type clutch.

Alternatively, in the embodiment in which the stopper 225 is provided on the inner handle shell and the one-way stopper claw 214 pivotally mounted by the pawl shaft 215 is mounted on the inner handle core assembly 22, the electric unit locks the one-way stopper claw 214 in some of the engaged state thereof, and the intelligent unlocking clutch mechanism may also be constituted.

As shown in fig. 3-5, an adapter key is inserted into a key hole of the main lock cylinder 31, a key pattern groove on the adapter key is matched with the unlocking pin 54 on the pin 51 arranged in the main lock cylinder 31 to drive the pin 51 to move back and forth along the extending direction of the pin 51 against a biasing force, after the adapter key is inserted in place, the unlocking openings 55 on the pin 51 are arranged on a straight line and opposite to the linkage sliding grooves on the main lock cylinder 31, the pin 51 limits the convex teeth 53 on the linkage sliding key 52 before the adapter key is not inserted, the convex teeth 53 on the linkage sliding key 52 can slide in the unlocking openings 55 arranged on a straight line, at the moment, the end part of the adapter key is pressed against the bent part 57 of the linkage sliding key 52, the adapter key is further pressed to drive the linkage sliding key 52 to approach the shifting wheel 32, the interlocking part 56 is inserted into the engaging groove 322 of the dial wheel 32 facing the interlocking part 56, so that the main lock cylinder 31 and the dial wheel 32 are in transmission connection and rotate synchronously in the circumferential direction. That is, the rotation of the adaptive key can drive the dial wheel 32 to rotate, and rotate towards the unlocking direction to drive the latch mechanism in the door lock to move towards the locking direction, thereby completing the unlocking process.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
