Description

Technical Field

[0001] This invention relates to the field of smart lock technology, and in particular to a mechanical anti-theft lock body, a space-separating security facility, and a control method for preventing jamming. Background Technology

[0002] Currently, for mechanical anti-theft lock bodies that are compatible with fully automatic smart locks, if the drive motor on the panel malfunctions and gets stuck during the locking process, the door lock cannot be opened from the inside.

[0003] In existing designs, fully automatic smart locks with mechanical anti-theft lock bodies often encounter a problem when the rear panel motor gets stuck during the locking process. Because the motor does not retract, the retraction space of the transmission component inside the lock body that performs the locking function is blocked, making it impossible to reverse the drive with the handle, thus preventing the door from being opened from the inside.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

Specifically, when the lock cylinder dial is engaged by a motor to abut against the second link, causing the main bolt connecting piece to extend and lock, if the lock cylinder dial cannot retract, the rotating shaft rotates in the forward direction to move the first link, causing the second cam fixing piece to push the third link to move. The third link abuts against the clutch pin, causing the third link to move relative to the second link, so that the main bolt connecting piece and the main bolt retract, and the first cam fixing piece, which moves synchronously with the second cam fixing piece, drives the top and bottom levers to retract and unlock the lock.

[0018] Beneficial effects: This invention provides a mechanical anti-jamming lock body, a space-separating safety facility, and a control method. In this mechanical anti-jamming lock body, when the lock cylinder is used for locking and the lock cylinder structure cannot be retracted, the rotating structure abuts against the anti-jamming component through the transmission component, causing the transmission component to drive the lock tongue component to retract.

[0045] The accompanying drawings have illustrated specific embodiments of the invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Disadvantages of existing technology: When the motor fails, it cannot be unlocked through internal operation, posing a safety hazard; after the motor is stuck, it requires professional repair, increasing repair costs and time; in emergency situations such as fire or earthquake, it cannot quickly open the door lock, affecting personnel evacuation.

[0048] To facilitate understanding, the application scenarios of the embodiments of this application will be introduced first:

[0049] The extension of the top and bottom lever indicates locking, and retraction indicates unlocking. The top and bottom lever of a fully automatic smart lock is an integral part of the lock body; its extension and retraction control the lock's open and close status. Specifically, when the lever is extended, the lock is locked, and the door or window cannot be opened from the inside, helping to prevent easy entry by external intruders. When the lever is retracted, the lock is unlocked, allowing residents to easily open the door or window from the inside for quick evacuation or daily activities. In abnormal use situations, such as fires or earthquakes, if a motor malfunction prevents the lock from opening normally, the top and bottom lever design becomes particularly important. Residents can easily unlock and open the door by simply rotating the shaft clockwise, which drives the lever, causing the upper connecting rod to retract the main bolt connecting plate, and simultaneously retracting the top and bottom lever, thus quickly unlocking the door and allowing for rapid evacuation.

[0050] In response to the aforementioned issue in related technologies where the rear panel motor of a smart lock malfunctions and jams during locking, blocking the retraction space of the transmission components within the lock body and preventing the door handle from reversing, thus preventing the door from being opened from the inside and posing a safety hazard, this application provides an anti-jamming mechanical anti-theft lock body, a space-separating safety device, and a control method. In this mechanical anti-theft lock body, when locking is performed using a lock cylinder and the lock cylinder structure cannot retract, the rotating structure abuts against the anti-jamming component through the transmission component, causing the transmission component to drive the bolt component to retract. Simultaneously, the top and bottom lever components retract to unlock, allowing personnel to unlock from the inside. This enables unlocking through internal operation even in the event of a motor malfunction, allowing for quick door opening in emergencies and improving safety. Therefore, this solves the technical problem in related technologies where the rear panel motor of a smart lock malfunctions and jams during locking, blocking the retraction space of the transmission components within the lock body and preventing the door handle from reversing, thus preventing the door from being opened from the inside and posing a safety hazard.

[0051] In this embodiment, when the motor fails, the rotating shaft rotates clockwise, driving the paddle to cause the first connecting rod to drive the second cam fixing plate, which in turn drives the third connecting rod to move to the left (see front view). The clutch pin is pushed downwards, causing the lower connecting rod to separate from the third connecting rod, and the main locking tongue connecting plate retracts. Simultaneously, the first cam fixing plate drives the top and bottom levers to retract. In this way, unlocking can be achieved through internal operation in the event of a motor failure, improving security.

[0052] This application embodiment enables unlocking via internal operation in case of motor failure, allowing for quick door opening in emergencies and ensuring personnel safety. It also reduces maintenance costs and time, extends the lifespan of the door lock, enhances its security, and avoids safety hazards caused by motor failure.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0054] Figure 1 The number in square brackets indicates the mechanism to which the component belongs. For example, 51(50) indicates that the lock cylinder dial belongs to the lock cylinder structure.

[0055] like Figure 1 and Figure 2As shown in the figure, this application embodiment provides a mechanical anti-jamming lock body, which includes: a cover plate assembly 10, a bolt assembly 20, a transmission assembly 30, a rotating structure 40, a lock cylinder structure 50, a top and bottom lever assembly 60, and an anti-jamming component 70; the bolt assembly 20 is connected to the transmission assembly 30, the rotating structure 40 and the lock cylinder structure 50 are respectively connected to the cover plate assembly 10, the transmission assembly 30 is respectively connected to the rotating structure 40 and the lock cylinder structure 50, the top and bottom lever assembly 60 is connected to the transmission assembly 30, and the anti-jamming component 70 is connected to the transmission assembly 30;

[0058] When the lock is engaged using a lock cylinder and the lock cylinder structure 50 cannot be retracted, the rotating structure 40 is used to abut against the anti-jamming component 70 through the transmission component 30, so that the transmission component 30 drives the lock tongue component 20 to retract, and the top and bottom lever components 60 retract to unlock so that personnel can unlock from the inside.

[0059] It is worth noting that the rotating structure 40 is connected to the handle.

The rotating structure 40 can also be used to lock and unlock the rotating shaft 41. The lock cylinder structure 50 is connected to the driving component (such as a motor). The driving component controls the rotation of the lock cylinder structure 50, thereby enabling the locking and unlocking of the lock cylinder.

[0060] Specifically, the cover plate assembly 10 includes an upper cover plate and a lower cover plate, the top and bottom lever assembly 60 and the locking tongue assembly 20 are located near the lower cover plate, and the transmission assembly 30 is located near the upper cover plate.

[0061] In one embodiment of the present invention, such as Figure 1As shown, the latch assembly 20 includes a main latch 21 and a main latch 21 connector. The main latch 21 is connected to the main latch 21 connector, and the main latch 21 connector is movably connected to the cover plate assembly 10.

The rotating shaft 41 is rotatably connected to the cover plate assembly 10, and the paddle 42 is fixedly connected to the rotating shaft 41. The lock cylinder structure 50 is a lock cylinder dial 51, which is rotatably connected to the cover plate assembly 10. The main latch 21 connector is connected to the transmission assembly 30. The paddle 42 is used to abut against and drive the transmission assembly 30 to move, and the lock cylinder dial 51 is used to abut against and drive the transmission assembly 30 to move.

[0062] Specifically, the cover plate assembly 10 forms a receiving space, and the rotating structure 40 is located on the right side of the space (see reference). Figure 1 The lock cylinder dial 51 is located on the left side of the space, and the transmission assembly 30 is located in the middle of the space.

[0063] In one embodiment of the present invention, the anti-jamming mechanical anti-theft lock body further includes a motor (not shown in the figure) connected to the cover plate assembly 10; the motor is connected to the lock cylinder dial 51 for transmission, and the motor is used to drive the lock cylinder dial 51 to rotate, so that the main lock tongue 21 connecting piece is locked or retracted.

[0064] In one embodiment of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the transmission assembly 30 includes a first cam fixing plate 31, a second cam fixing plate 32, and a connecting rod assembly 33; the main lock tongue 21 connector is connected between the first cam fixing plate 31 and the second cam fixing plate 32, one end of the first cam fixing plate 31 and one end of the second cam fixing plate 32 are connected by a toggle pin 321, and the toggle pin 321 abuts against the main lock tongue 21 connector; the first cam fixing plate 31 and the second cam fixing plate 32 are respectively connected to the connecting rod assembly 33, the toggle plate 42 is connected to the connecting rod assembly 33, and the lock cylinder toggle wheel 51 is used to abut against the connecting rod assembly 33.

[0065] In one embodiment of the present invention, such as Figure 1 , such as 3, Figure 5 and Figure 6As shown, the anti-jamming component 70 includes a clutch pin 71 and a clutch spring 72, with both ends of the clutch spring 72 connected to the clutch pin 71 and the cover plate assembly 10, respectively; the connecting rod assembly 33 includes a first connecting rod 331, a second connecting rod 332, and a third connecting rod 333; the first connecting rod 331 is connected to the cover plate assembly 10, and one end of the first connecting rod 331 is hinged to the paddle 42; the first connecting rod 331 is connected to the second cam fixing plate 32, and the first connecting rod 331 is used to drive the second cam fixing plate 32 to move; the second connecting rod 332 is connected to the second... Each of the connecting rods 332 has a clutch port. The clutch pin 71 passes through the clutch port, causing the second connecting rod 332 and the third connecting rod 333 to be engaged relative to each other. The second cam fixing plate 32 is used to drive the third connecting rod 333 to move. The third connecting rod 333 abuts against the clutch pin 71, causing the third connecting rod 333 to move relative to the second connecting rod 332. When the lock cylinder dial 51 abuts against the second connecting rod 332 and cannot retract, the main lock tongue 21 connecting plate and the main lock tongue 21 are retracted, and the first cam fixing plate 31 drives the top and bottom levers to retract and unlock.

[0066] Specifically, the outline of the first cam fixing plate 31 is "X" shaped, and the outline of the second cam fixing plate 32 is "V" shaped; the second connecting rod 332 and the third connecting rod 333 are fitted together, the second connecting rod 332 has a connecting groove, the anti-jamming component 70 is installed in the connecting groove, the clutch pin 71 is provided with a sliding rod, the sliding rod passes through both sides of the clutch pin 71 and is connected to the groove wall of the connecting groove of the second connecting rod 332, the groove wall has a lifting groove, so that the clutch pin 71 can move under the limit of the clutch port and the lifting groove, so as to achieve the purpose of disengaging the third connecting rod 333 from the second connecting rod 332, so that people can unlock it from the inside through the rotating shaft 41.

[0067] In this embodiment, the second link 332 and the third link 333 are used in conjunction with the clutch pin 71 to ensure that in the event of a motor locking failure, the main lock tongue 21 can be retracted via the rotating shaft 41 and the top and bottom lever assembly 60 can be retracted, thereby allowing the resident to unlock from the inside and improving security.

[0068] In one embodiment of the present invention, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the main latch 21 connecting piece is provided with a strip-shaped groove and an irregular groove. The actuating post 321 moves within the irregular groove. The cover plate assembly 10 is provided with a latch fixing post. The latch fixing post is movably connected to the strip-shaped groove, so that the main latch 21 connecting piece extends to lock or retracts to unlock. The first connecting rod 331 is provided with a first rivet, which is used to push the second cam fixing piece 32 to move when the first connecting rod 331 moves. The third connecting rod 333 is provided with a second rivet, which is used to push the second cam fixing piece 32 to move when the third connecting rod 333 moves.

The clutch spring 72 is movably connected to the cover plate assembly 10. One end of the clutch pin 71 is wedge-shaped. When the third linkage 333 moves toward the lock cylinder dial 51, it abuts against the clutch pin 71, causing the clutch pin 71 to disengage from the clutch port of the third linkage 333.

[0070] Below, in conjunction with Figure 1 , Figures 6-15 The working principle of the anti-jamming mechanical anti-theft lock body of the present invention will be further explained through specific embodiments:

[0071] I. Under normal use:

[0072] See Figure 6 and Figure 7 Locking of pivot 41: Pivot 41 rotates counterclockwise, driving the paddle 42, which in turn drives the third link 333, which in turn drives the second cam fixing plate 32, which in turn drives the main lock tongue 21 connecting plate to lock. At the same time, the first cam fixing plate 31 drives the top and bottom pull rod assembly 60 to extend.

[0073] See Figure 8 and Figure 9Lock cylinder locking: Lock cylinder dial 51 rotates counterclockwise, driving the lower connecting rod, the lower connecting rod drives the third connecting rod 333, the third connecting rod 333 drives the second cam fixing plate 32, driving the main lock tongue 21 connecting plate to lock, and at the same time the first cam fixing plate 31 drives the top and bottom pull rod assembly 60 to extend.

[0074] See Figure 10 and Figure 11 Unlocking the pivot 41: The pivot 41 rotates clockwise, driving the paddle 42, which in turn drives the first connecting rod 331. The first connecting rod 331 drives the second cam fixing plate 32, which in turn drives the main lock tongue 21 connecting plate to retract.

[0076] II. Abnormal usage conditions:

[0077] See Figure 14 and Figure 15 During the locking process, the motor malfunctions and locks, preventing the lock cylinder dial 51 from retracting. At this time, the shaft 41 rotates clockwise, driving the dial 42. The dial 42 drives the first connecting rod 331, which in turn drives the second cam fixing plate 32. The second cam fixing plate 32 drives the third connecting rod 333 to move to the left. At this time, the clutch pin 71 is pushed down, the lower connecting rod separates from the third connecting rod 333, the main lock tongue 21 connecting plate retracts, and the first cam fixing plate 31 drives the top and bottom lever assembly 60 to retract.

[0078] For example, this application also provides a space-separating security facility, wherein the anti-locking mechanical anti-theft lock body includes the anti-locking mechanical anti-theft lock body as described in any of the above solutions. It is understood that the space-separating security facility can be a door or a window.

[0079] The space separation security facility provided in this application has all the above-mentioned beneficial effects because it is equipped with a mechanical anti-theft lock body that prevents jamming as described in any of the above technical solutions, which will not be repeated here.

[0080] For example, such as Figure 3 As shown in the figure, this application embodiment also provides a control method for an anti-jamming mechanical anti-theft lock body, including the following steps:

[0081] In step S101, when locking is performed using a rotating shaft, the rotating structure drives the transmission assembly to move in a first direction, causing the latch assembly to extend for locking and the top and bottom lever assemblies to extend for locking; when unlocking is performed using a rotating shaft, the rotating structure drives the transmission assembly to move in a second direction, causing the latch assembly to retract for unlocking and the top and bottom lever assemblies to retract for unlocking.

[0082] In step S102, when locking using the lock cylinder method, the motor controls the lock cylinder structure to drive the transmission component to move along the first direction, so that the bolt assembly extends to lock and the top and bottom lever assembly extends to lock; when unlocking using the lock cylinder method, the motor controls the lock cylinder structure to drive the transmission component to move along the second direction, so that the bolt assembly retracts to unlock and the top and bottom lever assembly retracts to unlock.

[0083] In step S103, when the lock is locked using a lock cylinder and the lock cylinder structure is blocked by the transmission component and cannot retract, the rotating structure rotates to abut against the anti-jamming component through the transmission component, causing the transmission component to drive the lock tongue assembly to retract, and the top and bottom lever assembly to retract and unlock so that personnel can unlock from the inside.

[0084] In one possible implementation, in step S103, when the lock cylinder dial is controlled by the motor to abut against the second link, causing the main bolt connecting piece to extend and lock, if the lock cylinder dial cannot retract, the rotating shaft rotates in the forward direction to cause the dial to move the first link, causing the second cam fixing piece to push the third link to move. The third link abuts against the clutch pin, causing the third link to move relative to the second link, so that the main bolt connecting piece and the main bolt retract, and the first cam fixing piece, which moves synchronously with the second cam fixing piece, drives the top and bottom levers to retract and unlock.

[0085] The control method for the anti-jamming mechanical anti-theft lock body provided by the present invention is applied to the above-mentioned anti-jamming mechanical anti-theft lock body, thereby having all the beneficial effects of the above-mentioned anti-jamming mechanical anti-theft lock body, which will not be elaborated here.
