Description

Technical Field

[0001] This disclosure mainly relates to the field of lock cylinders, and in particular to a lock cylinder device and its lock body in the subfield of lock cylinders. Background Technology

[0002] In related technologies, on the one hand, traditional lock cylinder structures, with their homogeneous cylindrical shape, fail to meet expectations in terms of prevention and control, exhibiting inadequate execution of opening and closing functions and low efficiency. Furthermore, the misalignment of structural elements results in high precision costs. Despite thousands of patents for nested lock cylinders, the industry still faces a significant challenge: after component manufacturing, the inconsistent surface roughness between the inner hole of the lock cylinder shell and the outer surface of the lock cylinder shaft leads to wear and tear. During assembly, the inability to adjust the gap (greater than 0.05mm) renders the lock cylinder unusable. In particular, the "opening" defect of rotating the lock cylinder allows for unauthorized technical unlocking in dangerous conditions (lock cylinder free rotation swing amplitude greater than ±6°), posing a risk. The lock cylinder (single-handed) also exhibits potential risks of external damage and internal wear, making it brittle and detrimental to consumer safety. On the other hand, the structure inside the lock cylinder chamber, which houses the lock cylinder components and support plate, indirectly performs the opening and closing functions. This necessitates constraints imposed by parts within the lock cylinder chamber to achieve precise structural assembly positioning and gap control, thus increasing assembly requirements and manufacturing costs. The lock cylinder chamber sidewall has a connecting hole, and the lock cylinder seat of the lock cylinder assembly in the lock cylinder chamber component is fixedly connected to the inner side interface of the lock cylinder chamber. The lock cylinder of the lock cylinder assembly is held in the lock cylinder chamber with smooth reciprocating motion. A support plate is provided on one side wall of the lock cylinder chamber to support the lock cylinder assembly. The connecting hole on the side wall of the lock cylinder chamber, corresponding to the fine-thread screw hole on the support plate, is provided. The fine-thread screw hole is used to precisely adjust the tightness or looseness of the assembly gap between the lock cylinder and the lock cylinder seat at the shear interface of the lock cylinder assembly. It can also make relative movement along the lock cylinder towards the lock cylinder seat when the fine-thread screw rotates. When the deviation of the shear interface exceeds the allowable value during use, it will be reduced by appropriate compensatory adjustment of the fine-thread screw. A key interface groove is provided at the end of the lock cylinder chamber component. In the existing technology, the lock cylinder component (full coverage of the cylinder housing with equal cross-section) is manufactured in a composite process. The lock cylinder part cannot directly provide the opening and closing action of the key. The lock cylinder product must be combined with the preparatory parts (external incremental customized lock cylinder shell) process before the key can perform the opening and closing action of the braking element. Summary of the Invention

[0003] In view of this, the problem-oriented approach prioritizes security at its core. This invention provides a lock cylinder device that explores an integrated "core-based prevention and control" path. It addresses both prevention and mitigation, covering the entire lifecycle of the lock cylinder device. The flat lock cylinder device features a "small incision" barrier at the front of the sliding core plate, a stable core device with an externally mounted clamping component (covering the core portion), and is adapted to the lock body. This novel lock cylinder device employs targeted layout technology for prevention and comprehensive mitigation, effectively reducing potential security risks during use. Multiple measures enhance risk avoidance capabilities. The lock cylinder device (externally mounted) performs switching actions and enhances performance. A structural element configuration precision value stability control mechanism ensures prevention and compatibility while reducing costs. Each component performs its function and complements the others, demonstrating strength in the details. This solves the shortcomings of existing technologies, such as the mismatch in the structural precision values ​​of nested cylindrical lock cylinders (customized) and stacked lock cylinder component units (internal configuration). Existing technologies for lock cylinders (with full coverage of the cylinder housing) are limited by drawbacks such as weak external defense and difficulty in internal governance. It is like cutting off the feet to fit the shoes, showing weakness in key areas.

[0004] On one hand, the present invention provides a lock cylinder device for a lock body, including a cover plate, a lock cylinder seat, a core plate, a clamping member, and a braking element. The lock cylinder seat has an end panel and a connecting portion. The end panel has a key interface groove, and the connecting portion has a connecting hole that is fixed to a corresponding position of the lock body. The core plate also includes a key groove and a bolt, suitable for stacking the core plate on the outer flat interface between the cover plate and the lock cylinder seat and allowing parallel movement. The clamping member is disposed on the outer peripheral surface of the cover plate and the lock cylinder seat and constrains their internal space, presenting a ready-to-use lock cylinder device. The braking element includes a pin assembly and / or a leaf assembly, pre-installed on the plane of the lock cylinder device. The lock cylinder device also includes a portion of the cover plate and the lock cylinder seat covered by the clamping member along the length direction. The covered area and the relatively uncovered portion form an exposed area, and the near-end faces of the cover plate and the core plate are concealed by the end panel of the lock cylinder seat; wherein, the key groove is provided in the core plate, the bolt is connected to the end of the core plate, the core plate is adapted to be operated by key-oriented reciprocating movement or tossing operation on the bolt of the lock cylinder device located on the core plate, and the bolt on the core plate reciprocates between a first position and a second position; wherein, the braking element is distributed in the key groove of the core plate and forms a shear interface with the corresponding overlapping position of the cover plate interface, and includes a first interval and a second interval opposite to the first interval; wherein, the braking element is designed to move radially elastically within the lock cylinder device by the insertion and removal of the mechanical key.

[0005] Beneficial effects: Specifically, the external adjustment and internal control prevent toughness. Firstly, the lock cylinder device consists of stacked core plates on the outer flat interfaces, positioned between the cover plate and the lock cylinder seat and moving parallel to each other. Internal wear resistance is ensured, and the surface roughness of each outer flat interface layered structure is consistent and wear-resistant. For materials of the same type, the lower the surface roughness precision level, the easier it is to wear during the break-in period. Secondly, the clamping component is set on the outer peripheral surface of the cover plate and the lock cylinder seat, constraining their internal space. This results in a ready-to-use "E" shape for the lock cylinder device. Along the length direction, the covered portion of the cover plate and the lock cylinder seat by the clamping component forms a covered area, and the relatively uncovered portion forms an exposed area. Internal compensation maintains precise and certain gap control, and pre-installed braking elements provide... This design helps reduce the manufacturing difficulty and cost of lock cylinder components. The near-end faces of the cover plate and core plate are concealed by the end panel of the lock cylinder seat. The key interface slot on the end panel is a narrow, horizontally or vertically rectangular shape, corresponding to the key slot. The key decoding path promotes parallel movement of the core plate, changing the conventional key rotation decoding method where the user manually captures the orientation and activates the response. The key interface slot on the end panel limits the predetermined amplitude of the core plate's (angular momentum) free rotation and swing, ensuring external stability. The key translation core end face has a "small incision" barrier for protection, strictly regulating one key to open one lock. Furthermore, in emergency situations, the user manually captures the orientation and activates the progressive failure mechanism, avoiding technical unlocking and curbing violent acts such as drilling or prying the lock cylinder. The size of the key decoding path's curve and straightness, the shear interface gap, and the amplitude of the core plate's free rotation and swing directly determine the success of technical unlocking, ensuring a safe and reliable lock cylinder component with robust anti-theft capabilities. This integrated design, mutually reinforcing, prevents problems before they arise, addresses both the surface and the interior, and provides comprehensive protection against theft and loss.

[0006] In one optional embodiment, at least one of the clamping components is a clamping band, which, according to the scenario requiring deformation adaptability, maintains a stable state suitable for the adjustment mode of the force-bearing lock cylinder device to meet the design requirements of the expected measurement value. The portion of the clamping band covered by the clamping band forms the covering area on the body surface of the cover plate and the lock cylinder seat, and the body surface of the cover plate or the lock cylinder seat is provided with a pressure block, which is suitable for adjusting the tightness of the clamping band by deformation. The clamping band is located in the space next to the pressure block and is subjected to external force to deform into a compressed state.

[0007] Beneficial effects: The clamp belt allows for deformation adaptation to different scenarios, maintaining a stable state suitable for the control of the force-bearing lock cylinder device to meet the design requirements of the expected measurement values. The part covered by the clamp belt forms a coverage area on the surface of the cover plate and the lock cylinder seat, and the surface of the cover plate or the lock cylinder seat is provided with pressure blocks, which are suitable for adjusting the tightness of the clamp belt by deformation. The clamp belt is located in the space next to the pressure block and is subjected to external force to deform into a tight state. Appropriate compensatory control is used to reduce losses. There is no need to replace components. It is simple to manufacture, easy to operate, ready to use after assembly, and low in cost.

[0008] In one optional embodiment, at least one of the clamping components is a clamp, which is provided with screws and nuts. The portion of the clamp covered by the clamp forms a covered area on the surface of the cover plate and the lock cylinder seat, suitable for tightening or loosening by tightening the screws. Furthermore, the clamping component is connected to the surface contours of the cover plate and the lock cylinder seat with rounded corners. When the clamp precisely controls the tightening or loosening of the assembly gap at the shear interface between the core plate and the cover plate in the lock cylinder device, it can maintain stability and be suitable for relative movement along the core plate against the cover plate under force. When the shear interface deviation exceeds the allowable value during use, it will be reduced through appropriate compensatory adjustment by the clamp, avoiding the lock cylinder device from failing due to wear of a few micrometers and being discarded, thereby improving the service life of the lock cylinder device, making the most of repaired parts, and sustainably maintaining the stability and precision control mechanism of the lock cylinder device's operation. Furthermore, the manufacturing process of the lock cylinder device is improved, the assembly and adjustment accuracy of the lock cylinder device is determined, and the shear interface between the core plate and the cover plate is tightly joined, so that a 0.05mm feeler gauge cannot be inserted.

[0009] Beneficial effects: The clamp, equipped with screws and nuts, forms a covered area on the surface of the cover plate and lock cylinder seat, suitable for tightening or loosening the screws; the clamp components have rounded corners on the surface contours of the cover plate and lock cylinder seat; this facilitates precise control of the clamp components to tighten or loosen the assembly gap at the shear interface between the core plate and cover plate in the lock cylinder device, and allows for relative movement along the core plate while maintaining stability and suitable for bearing force; when the shear interface deviation exceeds the allowable value during use, the clamp components will appropriately compensate and reduce the damage, avoiding the failure of the lock cylinder device due to wear of a few micrometers, thus improving the service life of the lock cylinder device, making the most of the repaired parts, and sustainably maintaining the precise and stable control mechanism of the lock cylinder device during operation; it improves the manufacturing process of the lock cylinder device, ensuring the certainty of the lock cylinder device assembly and adjustment accuracy value, with the shear interface gap between the core plate and cover plate being at least less than 0.05mm, reducing the key cross-opening rate and common jamming faults, and contributing to the high-quality and sustainable development of the lock cylinder device. If the shear interface gap between the core plate and the cover plate is greater than 0.05mm, the clutch engagement process of the braking element is prone to jamming, leading to excessive force and breakage when the key is unlocked, and increasing the rate of key misoperation. It features flexible configuration, self-constraint, emphasis on control, simple manufacturing, convenient operation, ready-to-use assembly, and low cost.

[0010] In one optional embodiment, the lock cylinder seat has an edge, wherein the edge of the lock cylinder seat faces the core plate, and the edge of the lock cylinder seat is part of the lock cylinder seat, wherein the edge of the lock cylinder seat is provided with a through hole for bolt movement; and wherein the bolt on the core plate moves between a first position and a second position opposite to the first position in the through hole at the side end of the lock cylinder seat, and the braking element is distributed in the key groove of the core plate and the area covered by the overlapping portion of the outer interface of the cover plate, including a first interval and a second interval opposite to the first interval; wherein the key groove of the core plate and the area covered by the overlapping portion of the outer interface of the lock cylinder seat; wherein if the bolt retracts to the first position and extends to the second position at the proximal or distal end of the cover plate. The lock cylinder moves between the two positions. When the bolt is in the retracted position, it retracts from the second position into the cover plate, and the key moves from the second interval to the first interval relative to the overlapping position of the core plate and the cover plate interface. When the bolt is in the extended position, it extends outward from the cover plate to the second position, and the key moves from the first interval to the second interval relative to the overlapping position of the core plate and the cover plate interface. The parallel movement of the key path avoids the risk of key breakage due to rotation. The end panel of the lock cylinder seat covers the near end faces of the core plate and the cover plate. The key interface groove on the end panel of the lock cylinder seat corresponds to the key groove on the core plate. The key interface groove on the end panel of the lock cylinder seat is used to limit the rotational swing amplitude of the tool to less than ±6°.

[0011] Beneficial effects: The lock cylinder seat is formed with an edge. By facing the core plate with the edge of the lock cylinder seat, and the edge of the lock cylinder seat is part of the lock cylinder seat, the bolt on the core plate moves between a first position and a second position in the through hole at the side end of the lock cylinder seat. The braking element is distributed in the key groove of the core plate and the corresponding outer interface layer of the cover plate, covering the first interval and the second interval. The key groove of the core plate and the corresponding lock cylinder seat interface layer area; the bolt moves between the first position and the second position when it is retracted at the near end or far end of the cover plate, and the key path movement process avoids the risk of key rotation and breakage; the end panel of the lock cylinder seat covers the near end face of the core plate and the cover plate, and the key interface groove on the end panel of the lock cylinder seat corresponds to the key groove of the core plate. The key interface groove on the end panel of the lock cylinder seat is used to limit the rotation swing amplitude of the tool to less than ±6°. Furthermore, the edge of the lock cylinder seat is U-shaped along both sides of the core plate. The height of the lock cylinder seat edge is greater than the height of the core plate and extends to both sides of the cover plate. The cross-section of the cover plate is quadrilateral, and the cross-section of the core plate is quadrilateral. The core plate and the cover plate have similar shapes. Manufacturing is simple; the lock cylinder seat is produced by stamping and forming to near-net-shape, reducing costs and offering diverse forms to meet different usage scenarios. The near-end faces of the cover plate and core plate are concealed by the end panel of the lock cylinder seat (screened lock cylinder assembly). The key decoding path involves the core plate moving parallel back and forth (→), changing the conventional key rotation (○). Decoding is activated by manually capturing the orientation and timing, followed by decoding. The end panel has a key interface slot that limits the predetermined amplitude of the core plate's (angular momentum) free rotation and swing, preventing tin foil unlocking and avoiding technical unlocking. The integrated design of the lock cylinder components defines a security threshold. The size of the gap between the curved and straight sections of the key decoding path and the shear interface, as well as the amplitude of the core plate's free rotation and swing, directly determine the success or failure of technical unlocking. The bolt movement distance is determined according to actual needs.

[0012] In one alternative embodiment, the cover plate and the lock cylinder seat have edges formed, wherein the edges of the cover plate are directed towards the direction facing the core plate, and the edges of the cover plate are part of the cover plate, and the edges of the cover plate are grooved along both sides of the core plate, wherein the sum of the heights of the edges formed by the cover plate and the lock cylinder seat is less than the height of the core plate.

Each chamber has a chamber depth axis. The pin assembly is received within the chamber. Each plug pin includes a key-cutting target protrusion for intersecting with a key-cutting target formed on the key plate. The plug pin and the drive pin of the pin assembly are in planar contact, with a flat shear interface. The task allows the plug pin of the core plate and the drive pin of the cover plate to be released in situ and move radially elastically within the lock cylinder. The core plate is movably connected to the cover plate and is adapted for a key to move the bolt on the core plate, thereby switching the key's open and closed states on the core plate.

[0015] Beneficial Effects: Existing tumbler assemblies must be used in combination with the lock cylinder device of this invention to realize the product's function and thus demonstrate its value. The tumbler assembly includes a plug pin, a drive pin, a spring, and a sealing plate, including but not limited to multiple rows and columns distributed in multiple chambers on the core plate and cover plate. The tumbler assemblies distributed on the core plate and cover plate include multiple chambers with corresponding and consistent shapes, each chamber having a chamber depth axis. The tumbler assembly is received in the chamber. Each plug pin includes a key cut-targeting protrusion for intersecting with a key cut-target formed on the key plate.

The core plate is movably connected to the cover plate, suitable for the key to move the bolt on the core plate, thereby realizing the switching of the key's open and closed state of the core plate. This design is suitable for use with polygonal key cuts where the target contact head is off-center, and for tumbler assemblies where the plug pin and drive pin are in planar contact with each other, creating a flat shearing interface. It allows for the angle adjustment of a single polygonal plug pin to correspond to different coordinate positions of the key's cut target. In some tumbler assemblies, the plug pin and drive pin chambers are located in the exposed area of ​​the lock cylinder, facilitating the adjustment of the polygonal plug pin's angle as needed.

[0017] Beneficial Effects: Existing braking components must be used in combination with the lock cylinder device of this invention to achieve the product's function and realize its value. The core plate's key slot is used to set up a first section between the blade assembly chamber area and the corresponding lock cylinder seat interface layered area; the core plate's key slot is used to set up a second section between the tumbler assembly chamber area and the corresponding cover plate interface layered area. The core plate has several plug pin chambers, the cover plate has several drive pin chambers, and the core plate has several blade chamber slots for placing blades and springs. The edge of the lock cylinder seat has several blade chamber holes. The "double-blade tumbler arrangement" of the lock cylinder device provides diverse forms to meet users' higher security requirements.

[0018] In one optional embodiment, the lock cylinder device further includes a pivot and a bolt assembly; the core plate and the cover plate are assembled with an outer interface stacked structure, and the cover plate and the core plate are in contact with a flat interface; and the lock cylinder device is a stacked structure such that, when the interface between the cover plate and the core plate is in the stacked position, the cover plate and the core plate form a shear interface in the stacked position region of the interface between the cover plate and the core plate; the lock cylinder device is used to accept the arrangement of the pin assemblies and / or along the cover plate and the core plate. The pivot point is arranged with associated chambers on both sides; the bolt assembly includes a paddle and a rack, the paddle meshing with the rack, the paddle being provided at the distal end of the core plate, and the rack being provided at the side end of the lock cylinder seat, the core plate being movably connected to the cover plate, suitable for the key to paddle the paddle on the core plate to drive the rack, thereby realizing the key switching the opening and closing state of the core plate, wherein the pivot point is located between the cover plate and the core plate, neither penetrating the core plate nor in contact within the operating range of the key.

[0019] Beneficial effects: The lock cylinder device also includes a pivot, and the core plate and cover plate are assembled with an outer interface stacked structure, with the cover plate and core plate having a flat interface; and the lock cylinder device is a stacked structure such that when the interface between the cover plate and the core plate is in the stacked position, the cover plate and the core plate form a shear interface within the stacked position area of ​​the interface between the cover plate and the core plate; the lock cylinder device is used to accept the arrangement of the pin assemblies and / or the arrangement of associated chambers on both sides of a pivot point on the cover plate and the core plate; the bolt assembly includes a tooth and a rack, the tooth meshes with the rack, the tooth is provided at the distal end of the core plate, and the rack is provided at the side end of the lock cylinder seat, and the core plate is movably connected to the cover plate, suitable for the key to move the tooth on the core plate to drive the rack (bolt), thereby realizing the switching of the key to the open and closed state of the core plate, wherein a pivot point is set between the cover plate and the core plate, which neither penetrates the core plate nor is in contact within the operating range of the key plate. The key interface slot on the end panel of the lock cylinder seat corresponds to the key slot on the cylinder plate. When the key is inserted into the lock cylinder device, the key decryption process smoothly and repeatedly executes the (fixed-point) turning method of the lock cylinder to operate the teeth of the cylinder plate. The (fixed-point) turning method of the lock cylinder is a special case of a parallel lock cylinder device, which provides a variety of key operation paths for the lock cylinder device. The choice of which key interface slot to move and which to turn increases the difficulty of unauthorized technical opening by circumventing tools.

[0020] In one optional embodiment, the lock cylinder device is used to receive the drive pins arranged on the cover plate and the plug pins arranged on the core plate, and associated chambers are arranged on both sides of the pivot point. The center line of the key groove of the core plate at the pivot point forms an angle with the center line of the cover plate. The plug pins are distributed in the key groove area of ​​the core plate, and the drive pins are distributed in the corresponding key groove area of ​​the cover plate. The center line of the key groove of the core plate at the pivot point forms a left-right angle of 0 to 25° with the center line of the cover plate. The drive pins corresponding to the distribution of each plug pin of the core plate are repeatedly distributed in batches in the area of ​​the cover plate. Under the action of the pivot point of the cover plate and the core plate, the distribution range of each plug pin of the core plate corresponds to the area of ​​the cover plate. The transmission pins of the plate are distributed in two intervals, left and right, and one batch is selected from two batches. The task planning allows the insertion pin interval of the core plate and the corresponding left and right intervals of the transmission pin of the cover plate to be displaced and released to move radially elastically within the lock cylinder device. In this case, the insertion pin of the pin assembly and the transmission pin move radially elastically within the chamber hole of the lock cylinder device by inserting and removing the mechanical key. When the left and right sides of the cover plate have overlapping chamber holes, the transmission pin is in the decoding state when the mechanical key is inserted to align all the transmission pins with the shear interface. The center line of the key slot shifts from the right side to the left side. And when the mechanical key is removed to make the transmission pin move elastically to cross the shear interface between the core plate and the cover plate, it is in the locking state, and the bolt assembly remains in the locked position.

[0021] Beneficial Effects: Existing tumbler assemblies require the use of the lock cylinder device of this invention to achieve product functionality and realize its value. The lock cylinder device is used to receive the drive pins arranged on the cover plate and the plug pins arranged on the core plate, including but not limited to the arrangement of associated chambers on both sides of a pivot point. The plug pins are distributed in the key groove area of ​​the core plate, and the drive pins are distributed in the corresponding key groove area of ​​the cover plate. The center line of the key groove of the core plate at the pivot point has a left-right deviation angle of 0-25° with the center line of the cover plate. The drive pins corresponding to the distribution of each plug pin on the core plate are repeatedly distributed in batches in the area of ​​the cover plate. Under the action of the pivot point of the cover plate and the core plate, the distribution range of each plug pin on the core plate corresponds to the left and right intervals of each drive pin distribution on the cover plate, and one batch is selected from the two intervals. The locking cylinder is designed to allow for radial elastic movement within the cylinder by either the plug pin section of the core plate or the corresponding drive pin section of the cover plate. The plug pin and drive pin of the pin assembly move radially within the cylinder chamber by the insertion and removal of a mechanical key. When the cover plate has overlapping chambers on both sides, the drive pins are fully aligned with the shear interface by the insertion of the mechanical key, placing them in a decoding state. The key slot centerline shifts from a position slightly to the right to a position slightly to the left. Furthermore, the drive pins are elastically moved to a position between the core plate and cover plate by the removal of the mechanical key, placing them in a locking state, and the bolt assembly remains locked. The (fixed-point) toggle lock cylinder method is a special case of a parallel lock cylinder device, providing multiple key operation paths. The choice between which key slot to move and which toggle increases the difficulty of unauthorized opening by tools. The angle between the center line of the key groove set at a fixed point on the core plate and the center line of the cover plate is determined according to the actual rack movement distance. Alternatively, the transmission pins can be arranged on the left or right side of the cover plate.

The lock cylinder mechanism is operated by moving the bolt (or rack) of the key, which drives the bolt assembly. The main lock component has a key insertion slot on its near-end face that corresponds to the key interface slot on the end panel of the lock cylinder seat. When the key is inserted into the lock cylinder, the bolt moves smoothly or repeatedly during the key decryption process, providing multiple ways to operate the lock cylinder. The choice between moving or turning the bolt increases the difficulty of unauthorized opening by tools. Since the door frame lock body includes the lock cylinder and has the same function, it will not be elaborated further here.

The technical feature of the lock cylinder device of this application is that the electrical part of the intelligent control is supplied with power or control information by a power line through an active wiring port; wherein, the bolt assembly device is matched with the intelligent control mechanical mechanism, the mechanical lock cylinder device is connected to the bolt assembly, and the intelligent control mechanical mechanism is connected to the bolt assembly, suitable for driving the bolt assembly separately without interference; wherein, the active wiring port of the lock body device on the inner side of the door frame is located in the main lock component or the strike plate, and the lock body device can omit the existing door lock panel and the damaged door leaf body panel with the wide slot for installing the lock body. Providing a continuous and stable power supply for smart locks alleviates users' anxiety about short battery life, facilitates installation, improves assembly efficiency, and offers shock and anti-disassembly protection, thus reducing security risks during use. Current national standards require smart locks to be equipped with mechanical lock cylinders; improving the lock cylinder's resistance to violent damage effectively extends the lifespan of smart locks, mitigates risks and losses, and reduces user costs. The lock body device of this invention eliminates the need for existing door lock panels and the damaged door panel with its wide slot for installing the lock body, retaining only the lock cylinder components. It is simple, aesthetically pleasing, cost-effective, and up-to-date. The main lock components are located in the door frame, making it an essential and indispensable part of the lock body installation.

[0026] This invention discloses a structural innovation in the multi-integrated assembly and adjustment of a multi-faceted lock cylinder device with an outer interface. The invention provides a flat, multi-faceted lock cylinder device comprising an open assembly of stacked outer interfaces between the core plate, cover plate, and lock cylinder seat, along with a clamping component configuration. It also features a key interface slot on the lock cylinder seat. The parallel lock cylinder device (within-body assembly and adjustment) unit offers direct switching stability, consistent surface roughness of the multi-faceted structure of the outer interface, precise gap control, and a barrier protection feature where the key interface slot on the end panel restricts the core plate's free rotation and sway amplitude. This achieves long-term... Time-sensitive lock cylinder components ensure reliable technical performance. Addressing both the symptoms (enhanced lock cylinder performance) and the root cause (upgraded lock cylinder structure) is crucial, and on-demand adjustments to the lock cylinder component assembly are a vital step in this process, linking the components together to fill any gaps. Embodiments of this disclosure provide a lock cylinder component and its lock body. A brief overview of the embodiments is provided below to offer a basic understanding of some aspects of this disclosure. This overview is not a broad summary of this disclosure. It neither identifies key or essential elements of this disclosure nor describes its scope. Its sole purpose is to disclose some concepts of the embodiments in a concise form as a prelude to the more detailed description that follows.

[0027] This invention provides a diversified technical performance collaborative innovation control mechanism for lock cylinder devices. The high-quality replacement of lock cylinders aims to "maintain the stability of the lock cylinder device's accuracy value to cope with the uncertainty of changes in external factors (manufacturing grade, wear and tear)". It adapts to scenarios where deformation is required. The core plate, cover plate and lock cylinder seat are stacked and connected by hoop components. "The screened lock cylinder is ready to use". The simplified production process transforms the bottleneck and defects of the inefficient "small workshop" method of individual configuration into the favorable conditions of clustered batch production line with smooth and convenient conditions. More importantly, its production speed is several times faster than traditional methods, and the assembly quality is stable and the cost is reduced. The lock cylinder device's prevention and control compatibility is crucial for building a safe and reliable lock cylinder device with robust prevention and control capabilities. On the one hand, the key performance indicators of the lock cylinder device's qualified assessment technology are clearly quantified. The three agreed-upon values ​​for the stable state of the lock cylinder device's three-level prevention and control system are simultaneously achieved: first, the surface roughness accuracy of the stacked structure of the outer flat interface of the technical unit must be improved by at least one level; second, the precision control of the gap must be maintained at least less than 0.05mm; and third, the key interface groove of the entrance barrier protection end panel must limit the free rotation and swing amplitude of the core plate (angular momentum) to at least ±6°. The technical effectiveness of lock cylinder device risk management, through appropriate assembly and modulation, addresses industry difficulties and pain points. By focusing on the details of prevention and control with a focus on "quality + service," even small improvements can have a significant impact, concerning the success or failure of the lock cylinder and the safety of people's lives. On the other hand, addressing technical challenges can effectively solve the current dilemma of supply shortages of high-end products and overcapacity of mid-to-low-end products in the market for existing lock cylinder technology, affecting production capacity, efficiency, and quality. The advanced manufacturing process for lock cylinder components utilizes a "one-step" procedure for existing stock. Lock cylinder components (externally modified) employ a simplified manufacturing process not found in conventional lock cylinders (internal customized). The "screened lock cylinder, ready to use" approach means that the individual lock cylinder unit can independently perform the opening and closing actions of the braking element with a key, facilitating appropriate adjustment of the fit clearance, and easily adapting to various lock body specifications. High-quality replacement and improved quality are achieved by reducing the manufacturing difficulty and cost of lock cylinder components. In contrast, the existing "two-step incremental" method for lock cylinder products relies on a crucial step: "bulk, screenless lock cylinder with additional utilization." This refers to pre-installed component lock cylinders that are subsequently integrated into other parts in a composite process, requiring a key to perform the opening and closing actions of the braking element. Based on the precise control technology characteristics of stacked lock cylinder components, and utilizing existing manufacturing equipment, grouping technology is applied to ensure the geometric similarity of each part. This saves materials within the same group, and grouping processes improve processing accuracy and production efficiency, reducing processing costs. Part coding and scanning assembly create the necessary conditions for the digital production of lock cylinder components.The stacked structure of lock cylinder components emphasizes the correlation between technical features. The assembly and adjustment accuracy of the lock cylinder component structure (lifecycle) includes the designed processing methods (tolerance constants) and the actual usage process (gap variables). The uniquely designed application document for the lock cylinder component assembly structure features a layered, bottom-to-top stacked assembly and adjustment configuration at the outer interface, which excels in control (error correction) mechanisms. It compensates for existing (manufacturing process tolerances) or potential (wear gaps generated during use) gaps between the outer surfaces of each stack as needed, appropriately adjusting them through clamp connectors. This stable control mechanism maintains the lock cylinder component assembly and adjustment accuracy, contributing to the high-quality sustainability of the lock cylinder component. Improving the accuracy of theft control is the bottom line, preventing damage and extending service life. Improving the lock cylinder component structure and mechanism technical solutions preserves the beneficial technical effects brought by the improved assembly accuracy based on the stacked lock cylinder component assembly adjustment and control technology. Added value is provided by after-sales service and maintenance support, and the cost-effectiveness enhances customer satisfaction and the sense of gain from the product's excellent performance.

[0083] Embodiments of this disclosure are described in detail below with reference to the accompanying drawings. For clarity, components or structures well-known to those skilled in the art are not specifically described herein. It should be understood that the specific embodiments described herein are merely illustrative of this application, and this disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure sufficient and to fully convey the scope of this disclosure to those skilled in the art. In the drawings, for clarity, the dimensions and relative dimensions of layers and sections may be exaggerated. The same reference numerals in the drawings denote the same or similar elements.

[0084] It is worth noting that, according to the interpretation of GB 21556-2008 "General Technical Conditions for Lock Safety", Chapter 3 of this standard defines terms and definitions, such as: 3.2 Key, a part with a keyway and teeth or information carrier for opening and closing the lock; 3.7 Lock cylinder, a component with assembled lock cylinder and other parts (the lock cylinder and lock cylinder housing are classified as secondary configurations); 3.8 Lock cylinder, a part with a keyway that can directly transmit the key's action; 3.12 Lock body, the main component of the lock with assembled parts. The standard is outdated. Firstly, it lacks the terminology and definition for "layered lock cylinder device"; secondly, GB21556-2008 stipulates that fixed locks have a Class A durability of ≥100,000 cycles, and after the lock cylinder undergoes 100,000 cycles of testing, the parts must meet mechanical requirements. The lack of a test ensures the lock cylinder functions normally, making the qualification assessment requirements unquantifiable, i.e., the inspection items include the clearance value and requirements between the lock cylinder and the lock cylinder housing.

[0085] Referring to the national standard GB / T 1031-2009 regarding surface roughness, when the fit properties are the same and the precision grade is the same, the roughness value of smaller dimensions should be smaller than that of larger dimensions, and the roughness value of shafts should be smaller than that of holes. The rougher the surface, the easier it is to wear, causing the gap to gradually increase during operation. Therefore, the roughness value is related to the shape: non-circular hole diameter > circular hole (inner diameter surface) > shaft (outer diameter surface). In terms of fit properties and precision grade, the outer interface superimposed structure of lock cylinder components is superior to the inner and outer equal cross-sectional area insertion structure of the lock cylinder. The safety of the lock cylinder depends 30% on maintenance and 70% on assembly and adjustment. The fit gaps between the outer surfaces of each layer, which have already been (manufacturing process) or may be (wear gaps during use), are appropriately adjusted through connection methods to control theft and prevent damage. The technical solution of this invention improves the manufacturing process of lock cylinder components. The stable control mechanism for the precision value of lock cylinder components means that the same thing is done every time, ensuring the same quality for every product. Its technical effect is that the accuracy of the lock cylinder component's on-demand compensation mechanism runs through the entire process from design, production, and service life, maintaining the stability of the precision value of the lock cylinder component during operation. The stacked lock cylinder structure effectively prevents illegal activities such as using specialized tools like Kaba positioning readers and electric key-operated lock picks. Lock cylinder components can be manufactured and / or sold as modular units.

[0086] Specifically, this application proposes the concept of "outer interface stacked portion covering lock cylinder device structure." The "stacked lock cylinder device" includes a core plate, cover plate, lock cylinder seat, and clamping components. These components are functionally connected and are also key parts for assembly and adjustment. The technical features of the main component combination in the application's structure are divided into three levels: "component slave level - skill unit master level - system level." The "component slave level" refers to the main components in the solution. Specifically, the invention includes a core plate, cover plate, lock cylinder seat, and clamping components. The "(pre-installed) component slave level" refers to the technical function that can be achieved when at least one main component is assembled with other (related) components. The "skill unit master level" refers to the part of the solution that can independently achieve technical performance, usually composed of main components and other parts. The application of pre-installed braking components involves the stacked interface (combined variable dimensional constraint) skill unit of the stacked type lock cylinder device, which includes the stacking of the outer interface between the core plate, cover plate, and lock cylinder seat, and the clamping component configuration assembly for assembly adjustment and key switching of open and closed states. Advanced manufacturing technology is used to achieve its technical effect, accuracy, stability, and control mechanism. "System-level" refers to the overall invention, which is usually composed of various independent technical units. Specifically, the connecting part of the lock cylinder device in the application invention is provided with connecting holes that are fixed to corresponding positions on the lock body, and the lock body is suitable for installation on a door frame.

[0087] The ends of the lock cylinder are defined as follows: the "key insertion" end or "proximal" end of the lock cylinder is the user-facing end used to insert the key into the key slot; the "distal" end, in contrast to the "proximal" end, refers to the end not facing the user. When the key is fully inserted into the cylinder plate, the proximal and distal ends of the key correspond to the proximal and distal ends of the cylinder plate. The key plate notch target refers to the key teeth. The subset of keys, master key, and main key described here express the same content. The outer periphery of the lock cylinder is connected to the lock body or object. The term "connection" here includes common connection methods such as bolt connection, riveting, mating, pin, and adhesive (not illustrated). The term "above" in this document includes the stated number. The term "unlocking" as used herein refers to moving or turning the core plate with a key, which moves the target protrusions of the columnar and / or thin-plate braking elements perpendicular to it via the key's cutting target. When each insert pin and drive pin or blade is aligned at the flat shear interface formed by the core plate and cover plate, the locking mechanism is activated by pushing or pulling the key to complete the closing or opening task. The braking elements are arranged in interval codes distributed vertically and / or horizontally on both sides of a pivot point. The upper and lower, left and right intervals represent relative spatial positions and should not be limited to their literal meaning. In this document, the insert pin in the core plate chamber corresponds to the lower (half) tumbler, the drive pin in the cover plate chamber corresponds to the upper (half) tumbler, and the full tumbler in the lock cylinder refers to the splicing of the insert pin and drive pin at the shear interface, generating a separation (displacement) and engagement (in-situ) splicing state. Throughout this specification, for the sake of simplicity, the same reference numerals are used to indicate the same or similar components, emphasizing the consistency of their main functions, and secondly, differences in shape and size are preserved. "Core-based prevention and control" refers to a strategy that integrates lock cylinder technology, encompassing lock cylinder components, technical performance, prevention (the main preventative measure), and treatment (adjusting and addressing the root cause). This strategy includes modifying the lock cylinder's components to address specific issues, such as changing its dimensional constraints, replacing external components, adjusting as needed, and reducing costs. The resulting "core-based prevention and coordinated treatment" strategy highlights the crucial role of the lock cylinder components and the key value of its comprehensive capabilities.

[0088] The lock cylinder devices disclosed in this application can be used, but are not limited to, for adapting to lock cylinder devices and lock bodies, lock cylinder devices and smart lock bodies, lock cylinder devices and smart lock bodies, lock cylinder devices and bags, and lock bodies and door frames. It should be noted that, as shown in the figures, the specific structures of the bolt assembly and lock body in the embodiments are existing structures and will not be detailed here; in smart locks, the bolt assembly is typically driven by a motor. The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may include at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

The cover plate 21 is provided with several transmission pin chambers 312a (multi-row, multi-column, asymmetrically distributed). The quality of code interval storage is more important than the quantity of code points stored. The diagram shows the state when key 5 is inserted into the key interface slot 522 on the end panel 222 of the lock cylinder seat 22, indicating that key 5 pushes the bolt 4 on the core plate 23 to extend.

Figure 5 For when Figure 1 The right view shows the deformation of the lock cylinder device 20 after assembly and adjustment at the pressure block 11a, with the clamping band 11 configured. The lock cylinder device 20, with the clamping band 11, is deformed into a tightened state by applying external force to the space beside the pressure block 11a. The lock cylinder device 20 uses the clamping component 1 to adjust the accuracy value stably, providing self-constraint and emphasizing control.

Figure 8 The plug pin targeting contact 311b of the middle ball assembly 31 is located at the center, and the contact point between the transmission pin 312 and the plug pin 311 is a plane, which is consistent with the shear interface of the outer flat interface of the core plate 23 and the cover plate 21. Further extending the application scenarios, it is also applicable to situations where the plug pin 313 targeting contact 313b in the same regular polygonal ball assembly is off-center, and the angle can be adjusted to distribute multiple points as needed.

The core plate 23 and the cover plate 21 are assembled with an outer interface stacked structure, and the cover plate 21 and the core plate 23 are in contact with a flat interface. The lock cylinder device 20 is a stacked structure such that when the interface between the cover plate 21 and the core plate 23 is in the stacked position, the cover plate 21 and the core plate 23 form a shear interface 24 within the stacked position area of ​​the interface between the cover plate 21 and the core plate 23.

The core plate 23 is movably connected to the cover plate 21, which is suitable for the key 5 to move the bolt assembly on the core plate 23, thereby switching the open and closed states of the core plate 23 by the key 5. The cover plate 21, the lock cylinder seat 22, and the edge 221 of the lock cylinder seat are bound by a clamp 12. The clamp 12 uses screws 12a and nuts 12b to adjust the tightness between the cover plate 21 and the core plate 23 as needed. The other end of the lock cylinder seat 22 is provided with a connecting part 223, which has a connecting hole 20c for connecting and fixing the lock body 100 at the corresponding position.

[0096] Figure 16 For along Figure 15A half-sectional view of the cross-section at point BB of the lock cylinder device shows a pivot 25 fixedly positioned between the cover plate 21 and the core plate 23, neither penetrating the core plate 23 nor making contact within the operating range of the key plate 5. The key interface groove 522 on the end panel 222 of the lock cylinder seat 22 corresponds to the key groove 231 of the core plate 23. When the key 5 is inserted into the lock cylinder device 20, during the key 5's decryption and encoding process, the (fixed-point) pivoting method operates the core plate 23's paddle 41, driving the rack 42 to move. The (fixed-point) pivoting method is a special case of the (displacement) moving lock cylinder, providing the key 5 with diverse operating paths for the lock cylinder device 20. The choice between moving and pivoting the key interface groove 522 increases the difficulty of unauthorized technical opening by circumventing tools. When the shear interface 24 deviates beyond the allowable value during use, the screws 12a and nuts 12b of the clamp 12 will be used for appropriate compensation adjustment to reduce damage, preventing the lock cylinder component 20 from failing due to wear of a few micrometers and being discarded. This improves the service life of the lock cylinder component, makes the most of the repaired parts, and maintains the precision of manufacturing and assembly. The lock cylinder component's assembly and adjustment accuracy is certain, and the shear interface 24 between the core plate 23 and the cover plate 21 is tightly connected. A 0.05mm feeler gauge cannot be inserted, ensuring the normal function of the lock cylinder component during use. GB21556-2008 standard stipulates that the durability of fixed locks Class A is ≥100,000 cycles. After the lock cylinder has undergone 100,000 cycles of testing, the components must meet the mechanical requirements. However, it lacks the qualification to determine that the lock cylinder is functioning normally. After the test, the inspection items for the fit clearance value and requirements between the lock cylinder and the lock cylinder shell are not included. The on-demand compensation mechanism of the lock cylinder component 20 of this invention is also applicable to N times the 100,000 cycles of testing, still meeting the qualification assessment that the fit clearance value and requirements between the core plate 23 and the cover plate 21 are functioning normally.

[0097] Figure 17 for Figure 15 The top view of the removed lock cylinder seat shows that the lock cylinder device 20 is used to receive the pin assemblies 31 arranged and / or positioned on both sides of a pivot 25 between the cover plate 21 and the core plate 23 in the associated plug pin chamber 311a. The core plate 23 is movably connected to the cover plate 21. The key groove 231 of the core plate 23 is provided with the plug pin chamber 311a section and the corresponding cover plate 21 interface overlapping position area. During the key 5 decryption encoding process, the lock cylinder device 20 performs a shifting or swinging operation on the bolt assembly teeth 41 and rack 42 on the core plate 23. The core plate 23 has teeth 41 at its end, and the side edge 221 of the lock cylinder seat 22 has a through hole for the rack 42.

[0098] Figure 18 for Figure 17 The cover plate is arranged in a schematic diagram of the left and right intervals of the ball. The double intervals on the left and right sides of the cover plate 21 and pivot 25 are arranged in the associated transmission pin chamber 312a, which is consistent with the single interval arrangement of the core plate 23 in the plug pin chamber 311a. The cover plate 21 is a pivot chamber 25a.

[0099] Figure 19 for Figure 11 A schematic diagram of a key cut target provided in an embodiment of the movable lock cylinder device according to the present invention. Figure 11 The movable lock cylinder device 20 is shown with a pin tumbler assembly 31 and a blade assembly. Figure 19 The key ruler plate 5 has external milling groove cut targets 53 on both sides of the first interval, and round pin cut targets 52 and regular polygonal pin cut targets 51 on the plane of the key ruler plate 5. If the key ruler plate 5 has a reserved bolt displacement length, and the lengths of the first and second intervals of the key ruler plate 5 are related to the distribution of the braking elements, then the total length of the key ruler plate 5 is equivalent to the sum of the reserved bolt displacement length, the length of the first interval, and the length of the second interval. Another movable lock cylinder device 20 is equipped with a pin assembly 31, such as... Figure 1 If the key plate 5 has a second section with a pin tumbler cut target 52, then the total length of the key plate 5 is equal to the sum of the key's reserved bolt displacement length and the length of the core plate 23. Therefore, the length of the lock cylinder seat 22 is at least the sum of the reserved bolt displacement length, the length of the first section, and the length of the second section. The length of the core plate 23 is equal to the length of the lock cylinder seat 22 minus the reserved bolt displacement length.

[0100] Figure 20 for Figure 14 The diagram depicts four possible orientations of the contact 313b (offset from the center of the chamber) on a square plug pin 313 of the lock cylinder device 20, which is configured with a tumbler. With the tumbler at the same coordinate position, the key cut target 51 on the key scale plate 5 selects one orientation of the contact 313b on a square plug pin as the sub-key. Alternatively, the key cut target 51 on the key scale plate 5 may use all four orientations of the contact on a square plug pin as the master key. Similarly, without illustrating each case individually, another type of lock cylinder device 20 may be configured with a regular polygon of the pin assembly 31. This regular polygon includes, but is not limited to, a regular triangle, allowing the lock cylinder device 20 to configure the pins using three possible orientations of the contact on a regular triangular plug pin; it may also be a regular pentagon, allowing the lock cylinder device 20 to configure the pins using five possible orientations of the contact on a regular pentagonal plug pin; or it may be a regular hexagon, allowing the lock cylinder device 20 to configure the pins using six possible orientations of the contact on a regular hexagonal plug pin. It is also conceivable that... Figure 11 The key ruler plate 5 has a second section with a key cutting target 51. The key ruler plate 5 advances the moving lock cylinder device 20 to decode, preventing the risk of the key breaking due to twisting during operation. This invention is not limited to what is shown in the figures. Figure 19The polygonal cutout target 51 of the key scale shown is encoded as a sub-key. A sub-key will only have one of these subset (master) key cutout target possibilities. Therefore, one sub-key combination will not operate another sub-key combination, but the master key will operate all sub-key combinations. If it is recognized that the security of a sub-key in use will change or be accidentally lost, and the movable lock cylinder requiring protection does not want to be replaced, all possible predetermined positions of the key cutout target contact 313b can be swapped (one of them). The previously used sub-key is discarded, and reactivating another sub-key (one of the key scale groups) is simple, easy, and economical. The user can also use the subset (master) key group to address the problem promptly. The number of key scale groups can be supplied according to the user's actual needs.

[0101] Figure 21 for Figure 17 This is a schematic diagram of the key cut target 52 of the actuating lock cylinder device 20 according to some embodiments of the present invention. The coordinates 52 of the key cut target on the surface of the key scale plate 5 are randomly distributed, with unequal spacing in the longitudinal direction and different distances in the lateral direction. The number of pin combinations depends on different user needs, and the number of combinations in the illustration is not limited. The pin coordinates in the actuating lock cylinder device 20 are distributed in relative spatial positions above and below, and left and right within the fixed point range of the pivot 25, and are not limited to specific positions. The center line of the key groove 231 set at the fixed point of the pivot 25 on the core plate 23 has a left and right side deviation angle α of 0 to 25° with the center line of the cover plate 21. The length of the key scale plate 5 and the actuation angle value depend on the displacement distance of the locking bolt assembly actuated by the lock cylinder device 20, and can be determined according to the actual needs of the scenario. Generally, national and industry regulations stipulate that the bolt extension of the lock body in home doors should not be less than 25 mm. The key scale plate 5 actuates the locking cylinder device 20 from the side to avoid the risk of the key 5 being broken due to twisting during operation.

[0102] Figure 22 This is a schematic diagram of a lock body 100 device in the locked position according to some embodiments of a door leaf of the present disclosure. Figure 22The diagram shows the door leaf 61 (in an active state) and door frame 62 (in a stationary state) of the door frame 60. The door leaf 61 is equipped with two lock cylinder components 20 of the main lock component 101. The main lock component 101 contains the lock cylinder components 20 (for moving or actuating the lock cylinder components). The mounting holes of the main lock component 101 are fixedly connected to the inner interface of the door leaf 61 via bolts or screws. An inner handle 611 is located on the inner interface of the door leaf 61 in a vertical position, and an outer handle 611 is located on the outer interface of the door leaf 61 in a horizontal position. The pushing and pulling operations of the inner and outer handles 611 do not control the movement of the bolt 104, preventing unauthorized unlocking of the bolt 104 through the outer handle 611. A strike plate 105 is located on the inner interface of the door frame 62, and the fixing plate 105a of the strike plate 105 is fixedly connected to the door frame 62. Push the safety button 103 by hand to engage the locking bolt 104, which will remain in the positioning hole in the main lock component 101 (as shown by the arrow in the figure). Figure 22 The main lock component 101 has a latch 104 locked in the strike plate 105 on the door frame 62. The safety button 103 on the main lock component 101 is in the active state, thus preventing the door from being opened even with a compliant key 5. If the safety button 103 is in the unsecured state, the door can be opened with a compliant key 5.

[0103] Figure 23 for Figure 22 A partial view of the outer side of the door leaf with the door handle. Figure 23 The door frame 62 of the door frame 60 is shown, the outer handle 611 is fixedly connected to the door leaf 61 and restricts the rotation movement, and the key interface slot 522 of the lock cylinder device 20 is shown. Figure 23 The lock cylinder device 20 shown is adapted to the wood or metal panel material of the door leaf 61. The outer interface of the door leaf 61 exposes the near end face of the lock cylinder device 20 and the key interface slot 522. The key interface slot 522 is located close to the position of the outer handle 611, which does not affect the normal unlocking with the key 5, and generally also prevents tools from tending to unlock.

[0104] Figure 24 To provide with Figure 23 Partial views of the outer side of the door leaf 61 with different door handles show that one difference is that the outer handle 611 is a quarter-circular shell (ear handle), which is aesthetically pleasing and blends harmoniously with the installed door leaf 61 or door frame 62, changing... Figure 23The handle 611 has an incongruous design. Secondly, the lock cylinder device 20 is adapted to the metal panel material of the door leaf 61. The door leaf 61 is provided with a door leaf key insertion slot 122, and the key interface slot 522 of the lock cylinder device 20 is aligned with the key insertion slot 122 of the door leaf 61. The key 5 is inserted into the insertion slot 122 in the rectangle of the door leaf 61. The key insertion slot 122 of the door leaf 61 is located near the position range of the outer handle 611, which does not affect the normal unlocking with the key 5 and generally hinders the tool from unlocking. The insertion slot 122 of the key 5 in the rectangle of the inner interface lock main component 101 of the door leaf 61 is a narrow inlet slot, which is concealed. It makes it difficult for others to figure out the "core" (who moved and who changed it). In addition, the mechanical lock body 100 device of the present invention can omit the existing door lock panel and the damaged door leaf body panel with a wide slot for installing the lock body, which is simple, beautiful and cost-effective.

[0105] Figure 25 This is a schematic diagram of a lock body 100 device in the locked position according to some embodiments of a door frame of the present disclosure. Firstly, Figure 25The diagram shows the door leaf 61 (in an active state) and door frame 62 (in a stationary state) of the door frame 60. The door frame 62 is equipped with a main lock component 101, which is fixedly connected to the inner interface of the door frame 62 and the interior interface of the door frame 62. The main lock component 101 is equipped with a movable lock cylinder device 20. A strike plate 105 is installed on the interior interface of the door leaf 61, and its fixing plate is fixedly connected to the door leaf 61. The movable lock cylinder device 20 can be manually operated by pushing the key 5 to actuate the bolt 104, disengaging it from the strike plate 105 (as shown by the arrow in the diagram), leaving the main lock component 101 on the door frame 62 unlocked. Alternatively, the lock cylinder device 20 can be manually operated by moving the key 5 to actuate the bolt 104, disengaging it from the strike plate 105, leaving the main lock component 101 on the door frame 62 unlocked. Secondly, the main lock component 101 can be equipped with an active wiring port 106. The main lock component 101 contains an intelligent module for its electrical components, which electronically identifies and processes human biometric information, electronic information, and network communication information, and controls the opening and closing operation of the mechanical mechanism (not shown). The electrical components are supplied with power or control information via the active wiring port 106. Furthermore, a keyway on the bolt 104 matches the intelligent module's control mechanism. The electrical mechanism actuates the bolt 104 to disengage from the strike plate 105, leaving the main lock component 101 unlocked on the door frame 62. This allows the door leaf 61 to be pushed inwards and opened (as shown by the arrow in the figure). The invention discloses a technical solution where the lock cylinder device 20 is installed on the door frame 62. The main lock component 101 is equipped with the lock cylinder device 20 on the door frame 62. The high strength of the door frame 62 material helps the main lock component 101 resist impacts, reduce vibration, resist disassembly, and prevent deformation. When the door leaf 61 is in an unstable state of opening and closing, the main lock component 101 loses stability and the lock cylinder device 20 may become unstable, which may cause potential problems. When the door frame 62 is in a static state, it supports the main lock component 101 and maintains stability of the lock cylinder device 20.

[0106] Figure 26 for Figure 25A partial schematic diagram of the key insertion slot on the outer side of the door frame is shown. Further, the door leaf 61 or door frame 62 is provided with an insertion slot 122, which may be of card recognition type, RF (radio frequency) type, or infrared type. Furthermore, the key interface slot 522 of the lock cylinder device 20 corresponds to the key insertion slot 122 on the door leaf 61 or door frame 62, which may be of card recognition type, RF type, or infrared type. The main lock component 101 and the intelligent control device are distributed, which is beneficial to the intelligent control device's resistance to vibration and loosening, as well as its anti-disassembly capability, extending the service life of electrical components and improving the reliability of the intelligent module. The main lock component 101 is provided with an active wiring port 106 to ensure the power supply of electrical components and the connection of IoT control information sources, alleviating consumers' anxiety about the lock's (battery) battery life, saving on the production cost of smart locks. The new smart lock is an application terminal that upgrades the IoT function of smart locks with "IoT+", thereby improving the basic security performance requirements of smart locks and meeting users' convenience needs. Additionally, the intelligent lock body 100 device of the present invention can omit the existing door lock panel and the installation of the damaged door leaf body panel, which is simple, beautiful, safe and reliable, and cost-effective. The lock tongue assembly has a driven mechanical part and a strike box 105 for receiving the lock tongue 104. The main lock component 101 has a mounting hole for screw fixing to the inner interface of the door frame 60. The main lock component 101 is assembled with the door frame 60 at the corresponding door handle height position of the door leaf 61 or the door frame 62. The key insertion slot 122 of the main lock component 101 is characterized by a narrow slot in the shape of a horizontal rectangle or a vertical rectangle on the outer interface of the door frame. The key 5 moves to operate the bolt assembly of the lock cylinder device 20. The rack 42 of the bolt assembly drives the lock tongue assembly. And, the door frame 62 near A key insertion slot 122 is provided on the end face. A lock cylinder device 20, concealed within the door frame, has a key interface slot 522. This slot 522 corresponds to the key plate receiving the key in the key slot 231 of the core plate 23. The key 5 is further inserted into the lock cylinder device 20. During the key 5's decryption process, the lock cylinder device 20 is operated smoothly by moving or turning the lock cylinder, causing the bolt 104 to move. This provides the key 5 with multiple ways to operate the lock cylinder device 20, ensuring anti-pry, anti-disassembly, and damage prevention, and preventing unauthorized opening by tools, thus increasing the difficulty of entry. The uncertainty of the predetermined movement or turning method of the key 5 through the same key insertion slot 122 on the door frame 60 makes it difficult for others to predict (which movement or turning), delaying the decryption time and hindering unauthorized opening attempts, rendering them futile. Keeping pace with the times, the main lock component 101 is located in the door frame 62 (in a static state), which is an important part of the lock body 100 installation position and cannot be absent. The smart lock body is equipped with a power cord interface 106 to prevent users from being embarrassed by insufficient battery power or no power, thus alleviating their worries.

[0107] In the accompanying drawings, for clarity, the sectional views of the door leaf and door frame are simplified, and the dimensions and relative dimensions of the layers and sections may be exaggerated. In the embodiments, the lock body and strike plate are applicable to both room door leaves and door frames, as well as cabinet door leaves and cabinet door frames. The same reference numerals in the drawings indicate the same or similar elements. The lock body device described herein is adapted to both inward-opening and inward-opening right-opening doors, and also to outward-opening left-opening and outward-opening right-opening doors. Deeply cultivated market application scenarios include, but are not limited to, lock body assembly in door frames, vehicles, drawers, safes, boxes, and padlocks. Lock body security performance is a systematic project, comprehensively considering the layout and key density of braking components, the precision of lock cylinder assembly, the maintenance and stability control mechanism, and the static state of the main lock components installed in the same frame, pursuing a stable and innovative advancement in the installation of the main lock components in the same frame. The core lock cylinder component storing the password range is a key technical component product. The lock body is a durable good; these three major technical elements are integrated into one, complementing each other for comprehensive and coordinated management, avoiding the failure of working alone.

[0108] Furthermore, the term "and / or" as used in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. The above description includes examples of the invention. Of course, it is impossible to describe every conceivable combination of components or methods for the purpose of describing the invention, but those skilled in the art will recognize that many other combinations and substitutions of the invention are possible. Therefore, the invention is intended to cover all such changes, modifications, and variations falling within the spirit and scope of the appended claims.
