[0036] To address the problem of poor compatibility of existing locks with door frames of different structures, this invention provides a lock and a door, wherein the door includes the lock described below.

[0037] like Figures 1 to 12 The lock shown includes a magnetic suction assembly 10 and a snap box assembly 20 mounted on a door frame 50. The snap box assembly 20 has mounting holes 21 on multiple sides for mounting the magnetic suction assembly 10. The magnetic suction assembly 10 is detachably disposed in the mounting holes 21 and can switch the mounting position between the mounting holes 21 on different sides.

[0038] In this embodiment, mounting holes 21 are provided on different sides of the snap box assembly 20. This allows the magnetic suction assembly 10 to be installed by correspondingly engaging with the mounting holes 21 on the different sides of the snap box assembly 20 when the snap box assembly 20 is used to adapt to the structure of the door frame 50. In this way, only one magnetic suction assembly 10 is needed to ensure the compatibility of the lock with door frames 50 of different structures, and at the same time, it ensures that the magnetic suction assembly 10 is installed in a position that can engage with other structures of the lock. This improves the compatibility and adaptability of the lock with door frames 50 of different structures. At the same time, the detachable and switchable nature of the magnetic suction assembly 10 reduces the need for additional magnetic suction assemblies 10 due to changes in the installation position of the snap box assembly 20, thus saving costs.

[0039] It should be noted that the lock in this embodiment also includes a lock body assembly 30 mounted on the door panel. The lock body assembly 30 and the strike box assembly 20 are arranged opposite to each other. The cooperation between the lock body assembly 30 and the strike box assembly 20 enables the locking and unlocking of the lock. The lock body assembly 30 has a Hall element 382, ​​which can sense the magnetic component 10 and provide feedback on the door opening and closing information. When the lock is locked, the Hall element 382 and the magnetic component 10 must be close to each other to ensure that the Hall element 382 senses the magnetic component 10 and triggers it, thereby providing the user with real-time feedback on the door opening and closing status. Therefore, the magnetic component 10 should be installed on the side of the strike box assembly 20 that is opposite to the lock body assembly 30. The mounting holes 21 on multiple sides of the strike box assembly 20 in this embodiment ensure that when different sides of the strike box assembly 20 are opposite to the lock body assembly 30, the magnetic component 10 can be installed into the mounting holes 21 on the corresponding side.

[0040] In some embodiments, the magnetic attraction assembly 10 includes a magnetic element 11 and a flexible sleeve 12, with the flexible sleeve 12 fitted onto the magnetic element 11 to reliably fix the magnetic element 11 and the flexible sleeve 12. Specifically, as... Figure 5 As shown, the magnetic component 11 can be a cylindrical, prismatic, or other shaped magnet, and the flexible sleeve 12 can be a silicone rubber component with an opening on one side. The flexible sleeve 12 is generally cylindrical, with one bottom surface of the cylindrical structure serving as the opening side. The interior of the flexible sleeve 12 is hollow to accommodate the magnetic component 11, which is inserted from the opening side of the flexible sleeve 12. Preferably, the opening side of the flexible sleeve 12 is not completely open; instead, an annular limiting structure is provided at the edge of the opening side, connecting to the outer peripheral surface of the flexible sleeve 12. That is, the size of the opening of the flexible sleeve 12 is smaller than the size of the cross-section of the magnetic component 11 parallel to the opening side, thereby ensuring that the magnetic component 11 can reliably reside inside the flexible sleeve 12 and preventing the magnetic component 11 from detaching.

[0041] In some embodiments, the magnetic component 11 is engaged with the mounting hole 21 by a flexible sleeve 12, thereby ensuring reliable installation of the magnetic absorbing assembly 10 and the snap-fit ​​assembly 20. Specifically, the outer periphery of the flexible sleeve 12 has a snap-fit ​​structure 121, which engages with the sidewall of the mounting hole 21. The mounting hole 21 is countersunk, comprising a countersunk section and a straight section connected in sequence. The countersunk section has a larger diameter and a shorter length than the straight section. The magnetic absorbing assembly 10 is installed into the mounting hole 21 from the countersunk section, which facilitates the smooth installation of the magnetic absorbing assembly 10. The snap-fit ​​structure 121 can be configured as an annular protrusion around the outer periphery of the flexible sleeve 12, or multiple protrusions can be spaced apart along the outer periphery of the flexible sleeve 12. The annular protrusion or the protrusions abut against the sidewall of the straight section, thereby utilizing the high coefficient of friction and anti-vibration characteristics of the flexible sleeve 12 to reliably fix the magnetic component 11 in the mounting hole 21, thereby improving the adaptability and stability of the magnetic component 11 in different installation environments, and better ensuring the performance of the magnetic component 11. The snap-fit ​​structure 121 may also include a protruding structure at the end of the flexible sleeve 12. The protruding structure and the annular limiting structure on the opening side are located at opposite ends of the flexible sleeve 12. The protruding structure runs around the outer periphery of the flexible sleeve 12, protruding beyond other parts of the outer periphery of the flexible sleeve 12, and is flush with the end of the flexible sleeve 12. This allows the protruding structure to abut against the side wall of the countersunk section, thereby reliably fixing the magnetic suction assembly 10 in the mounting hole 21 and preventing the magnetic suction assembly 10 from loosening. Of course, the shape of the magnetic component 11 and the material and shape of the flexible sleeve 12 can be adjusted according to actual needs to ensure the magnetic attraction characteristics of the magnetic suction assembly 10 and reliable installation with the snap-fit ​​assembly 20.

[0042] In some embodiments, the lock further includes a lock body assembly 30, which has a retractable bolt 31. The strike box assembly 20 has multiple mounting slots 22 for accommodating the bolt 31. Multiple sides of the strike box assembly 20 are provided with mounting slots 22. When the bolt 31 is extended, at least a portion of the bolt 31 can be switched within one of the mounting slots 22, allowing at least a portion of the bolt 31 to be positioned within a specific mounting slot 22 during use. This enables the bolt 31 to be switched to different mounting slots 22 as needed. Thus, when the strike box assembly 20 is installed on door frames 50 with different structures, the bolt 31 can always cooperate with the mounting slot 22, thereby improving the flexibility and adaptability of the lock. Specifically, the mounting slot 22 can be a rectangular slot to adapt to the shape of the bolt 31, which has a rectangular cross-section. Of course, the shape of the mounting slot 22 can be adjusted accordingly based on different shapes of the bolt 31. The lock in this embodiment also includes a housing assembly 40. The housing assembly 40 has an installation space for mounting the lock body assembly 30. The bolt 31 is telescopically configured relative to the housing assembly 40. The installation space has a side opening for the bolt 31 to enter and exit. At least a portion of the bolt 31 can extend or retract into the installation space through the side opening. The side opening is opposite to the mounting groove 22. That is, the bolt 31 is telescopically configured relative to the snap box assembly 20. At least a portion of the bolt 31 can extend into or retract from the mounting groove 22. Since multiple sides of the snap box assembly 20 are provided with mounting grooves 22, when the snap box assembly 20 is used with door frames 50 of different structures, it can ensure that the side opposite to the side opening has a mounting groove 22 to accommodate the bolt 31. In this way, it can be ensured that one of the multiple mounting grooves 22 can always be used to accommodate the bolt 31 in different installation environments, thereby ensuring the compatibility of the lock with door frames 50 of different structures. Of course, in other embodiments not shown in the figure, the connection method between the latch 31 and the snap box assembly 20 and the design of the mounting groove 22 may also be different, for example, the position of the latch 31 may be adjusted by a rotation or sliding mechanism.

[0043] Considering that both the magnetic component 10 and the mounting groove 22 are used in conjunction with the lock body assembly 30, preferably, the sides with mounting holes 21 are all provided with mounting grooves 22. This ensures that the magnetic component 10 and the bolt 31 can mate with the same side of the latch assembly 20, thereby guaranteeing a reliable fit with the lock body assembly 30 and avoiding functional loss of the lock due to positional deviation between the magnetic component and the bolt 31. Specifically, the latch assembly 20 in this embodiment has a prismatic outline, specifically... Figures 1 to 4The cuboid structure shown includes a snap-fit ​​assembly 20, which comprises a cuboid snap-fit ​​box. Mounting grooves 22 and mounting holes 21 are located on different sides of the snap-fit ​​box. The snap-fit ​​assembly 20 also includes screws 25 for fixing the snap-fit ​​assembly 20 to the door frame 50 and a snap-fit ​​cover 26 for engaging with one side of the snap-fit ​​box. Figure 4 As shown, mounting grooves 22 and mounting holes 21 are provided on two adjacent sides of the latch box. When one side is used in conjunction with the latch 31 and the magnetic assembly 10, the latch box cover 26 is used to cover the other side, thereby ensuring the integrity of the appearance of the latch box assembly 20 and ensuring the security of the latch box assembly 20 when locked with the lock assembly. Preferably, the mounting grooves 22 and mounting holes 21 are located on the larger side of the cuboid latch box, and the mounting grooves 22 and mounting holes 21 can be arranged along the length of the cuboid.

[0044] In some embodiments, the side of the snap box assembly 20 includes a first side surface 23 and a second side surface 24. The first side surface 23 and the second side surface 24 are arranged adjacent to each other along the circumference of the snap box assembly 20. Both the first side surface 23 and the second side surface 24 are provided with mounting holes 21 and mounting grooves 22, thereby providing multiple directional options for the installation of the snap box assembly 20, allowing the lock to flexibly adapt to different door types and installation environments. Specifically, the first side surface 23 and the second side surface 24 are both sides of a cuboid snap box. Their adjacent arrangement means that the first side surface 23 and the second side surface 24 face different directions, thus allowing different sides to be selected as mating surfaces with the lock body assembly 30 for different door frame structures 50, such as... Figure 2 The door frame 50 shown can have its second side 24 selected as the mating surface for the lock body assembly 30, such as... Figure 3 As shown, the first side surface 23 can be selected as the mating surface for cooperating with the lock body assembly 30, thereby improving the adaptability of the snap box assembly 20. Preferably, the mounting holes 21 and mounting grooves 22 on the first side surface 23 are arranged in the opposite direction to those on the second side surface 24. That is, the mounting holes 21 can be located in the middle of the side surface, and the mounting holes 21 on the first side surface 23 and the second side surface 24 are located at the two ends of the snap box, respectively. This ensures that there is sufficient space inside the snap box for setting the mounting holes 21, avoiding the two mounting holes 21 from intersecting and causing partial loss of the sidewall of the mounting hole 21, which would affect the stability of the magnetic assembly 10 installation. Of course, in addition to the embodiments described above, in other embodiments not shown, additional mounting holes 21 or improved positioning structures can also be considered to further enhance the convenience of installation and the stability of the lock body structure.

[0045] In some embodiments, the lock body assembly 30 includes a bolt 31, a first transmission member 32, and a switch assembly 33. The bolt 31 is an integral structure; the first transmission member 32 is operatively connected to the bolt 31; the switch assembly 33 is connected to the first transmission member 32 and can drive the bolt 31 to extend into or retract from the strike box assembly 20 via the first transmission member 32, thereby locking and unlocking the lock body assembly 30 and the strike box assembly 20. Specifically, when the bolt 31 extends from the side opening of the housing assembly 40, it can extend into the mounting groove 22 of the strike box assembly 20, thereby locking the lock body assembly 30 and the strike box assembly 20 to close the door. When the bolt 31 retracts from the mounting groove 22, it unlocks the lock body assembly 30 and the strike box assembly 20 to open the door. The lock body assembly 30 can be configured as a plate-like structure with a certain thickness, or as a hollow three-dimensional structure, which facilitates the installation of other auxiliary closing components inside the bolt 31. The latch 31 in this embodiment comprises two parts. One part is plate-shaped with irregularly shaped notches on its edges, which are used to engage with the first transmission member 32. The other part is a hollow cuboid structure used to extend into or out of the mounting groove 22 to engage with the latch assembly 20. Although the latch 31 is functionally divided into two parts, this embodiment adopts an integrated structure to ensure the strength of the latch 31. The latch 31 can be integrally die-cast from stainless steel or injection molded from metal powder, thereby giving the latch 31 higher dimensional accuracy and tensile strength. The first transmission member 32 can be configured as a dial wheel. The first transmission member 32 has an internally hollow annular segment and a transmission arm extending radially along the annular segment. The annular segment is used to engage with the switch assembly 33, and the extension arm is used to engage with the notch of the latch 31. Thus, when the switch assembly 33 drives the annular segment to rotate, the extension arm drives the latch 31 to extend and retract through the notch, thereby converting the rotation of the first transmission member 32 into the linear motion of the latch 31, thus realizing the opening and closing of the door.

[0046] like Figure 11As shown, in some embodiments, the lock body assembly 30 further includes a latch 34 and a rivet 35. The latch 31 has a mounting cavity for mounting the latch 34. When the latch 31 is located inside the snap box assembly 20, at least a portion of the latch 34 is located outside the mounting cavity and engages with the snap box assembly 20. The latch 34 is rotatably connected to the latch 31 via the rivet 35, thereby further ensuring the reliability of the lock body assembly 30 when locked to the snap box assembly 20, and ensuring the structural stability of the lock body assembly 30. Specifically, the rivet 35 can be a rivet, and there can be two latches 34, which are symmetrically arranged in the mounting cavity along the center line of the latch 31. The mounting cavity has openings on opposite sides, and the two openings are symmetrically arranged along the center line of the latch 31. The two rivets penetrate the entire mounting cavity, thereby reliably fixing the two latches 34 in the mounting cavity and enabling them to rotate relative to the latch 31. When the latch 34 rotates, at least a portion of the latch 34 can extend out of or retract into the mounting cavity from the opening. Thus, when at least a portion of the latch 31 is located within the snap box assembly 20, that is, when at least a portion of the latch 31 is located within the mounting groove 22, and the snap box assembly 20 and the lock body assembly 30 are locked, at least a portion of the hook tongue 34 can extend from the mounting cavity and engage with the side wall of the mounting groove 22, thereby preventing the latch 31 from easily dislodging from the mounting groove 22, thus improving the security and reliability of the lock. In this embodiment, the latch 31 and the hook tongue 34 are riveted together by the riveting member 35, which can strengthen the overall tensile strength of the hook tongue 34 and effectively control the assembly clearance between the two hook tongues 34, thereby increasing the service life of the latch 31 and improving the overall quality of the lock body assembly 30. It should be noted that the centerline of the latch 31 refers to the axis of symmetry of the latch 31 along the extension and retraction direction of the latch 31.

[0047] In some embodiments, the latch 31 has a position detection unit 311, and the lock body assembly 30 further includes a sensor 36. The sensor 36 is used to sense the position detection unit 311 to detect the position of the latch 31, thereby enabling accurate detection and feedback of position changes of the latch 31. This avoids the wear problems caused by traditional mechanical micro-motion contact switches, thus ensuring the stability of the lock during long-term use. Specifically, the position detection unit 311 and the latch 31 can be integrally formed using metal powder injection molding technology to ensure their stability. The position detection of the latch 31 can adopt an optocoupler reflection scheme, that is, the sensor 36 is set as an optocoupler. When the latch 31 extends or retracts, the position detection unit 311 moves synchronously, thereby triggering the optocoupler to provide signal feedback, thereby achieving accurate detection of the position of the latch 31. Moreover, each position detection of the latch 31 does not cause actual physical wear to other components such as the circuit board 381, which helps to improve the service life of the lock body assembly 30.

[0048] In some embodiments, the lock body assembly 30 further includes a second transmission member 37 and a drive assembly 38. The second transmission member 37 is driveably connected to the first transmission member 32, and the drive assembly 38 is driveably connected to the second transmission member 37. The second transmission member 37 and the first transmission member 32 drive the bolt 31 to move. The switch assembly 33 can control the action of the drive assembly 38, thereby providing a second driving method for the bolt 31 and forming a linkage with the first driving method, i.e., the method that is only driven by the first transmission member 32. This allows the two driving methods to coexist, thereby improving the flexibility of the lock. Specifically, the second transmission member 37 can be configured as a gear, with a gear pressure plate 371. The gear and the annular segment of the dial are coaxially arranged and sleeved on the outer side of the annular segment. The drive assembly 38 drives the gear to rotate, the gear drives the dial to rotate, and the dial in turn drives the bolt 31 to extend and retract, thereby realizing the opening and closing operation of the lock. Preferably, the activation of the drive assembly 38 can be controlled by the switch assembly 33, allowing the user to select a driving method through the switch assembly 33 to open and close the door.

[0049] like Figure 9 , Figure 10 As shown, in some embodiments, the switch assembly 33 includes a rotating member 331 and a pressing member 332. The first transmission member 32 is located inside the rotating member 331, and the rotating member 331 is connected to the first transmission member 32 and can drive the first transmission member 32 to rotate synchronously. The pressing member 332 is inserted inside the first transmission member 32 and is axially movable relative to the rotating member 331 and the first transmission member 32. The pressing member 332 is used to control the action of the drive assembly 38. In this way, the switch assembly 33 integrates the two main parts of the rotating member 331 and the pressing member 332. The first transmission member 32 is located inside the rotating member 331 and connected to it, so that the rotation of the rotating member 331 can directly drive the first transmission member 32 to rotate synchronously, thereby realizing the opening and closing operation of the mechanically driven latch 31 assembly. The pressing member 332 is inserted inside the first transmission member 32, thereby allowing the user to control the drive assembly 38 through the pressing action, thereby driving the gear and causing the latch 31 assembly to perform linear back-and-forth extension and retraction motion to complete the electronically driven opening and closing operation of the latch 31. This integrated design not only optimizes the user experience and simplifies operation steps, but also enables more precise and stable control of the latch 31. During operation, the separate control mechanism of the rotating component 331 and the pressing component 332 ensures that users can choose the appropriate unlocking method according to their actual needs. Whether it is mechanical or electronic drive, it can be executed smoothly and accurately, which can improve the practicality and reliability of the lock body structure.

[0050] Specifically, the side of the switch assembly 33 furthest from the latch 31 is exposed in the housing assembly 40 for easy operation. The housing assembly 40 includes a base plate 43 and a cover 41, with the cover 41 covering the base plate 43 to form an installation space for mounting the lock body assembly 30. The housing assembly 40 also includes a bracket 42, which is disposed within the installation space and has a through hole for mounting the switch assembly 33. This allows part of the switch assembly 33 to be located within the installation space and cooperate with the first transmission member 32, the second transmission member 37, and the drive assembly 38, while the other part is located outside the installation space for easy user operation.

[0051] In some embodiments, the switch assembly 33 further includes a limiting plate, which is plate-shaped and located on the side where both the rotating member 331 and the pressing member 332 are away from the housing assembly 40. This limiting plate confines the pressing member 332 within the rotating member 331 along the axial direction of the switch assembly 33, preventing the pressing member 332 from disengaging. The rotating member 331 is a hollow cylindrical structure, and its side near the housing assembly 40 abuts against the bracket 42 axially. It is rotatable relative to the bracket 42, allowing the rotating member 331 to rotate and extend / retract the locking tongue 31. The pressing member 332 is also cylindrical, comprising a large-diameter section, a small-diameter section, and a medium-diameter section with an outer diameter between the large and small diameter sections. The large-diameter section, medium-diameter section, and small-diameter section are sequentially connected axially. The large-diameter section abuts against the limiting plate, allowing the pressing member 332 to move axially when the limiting plate is pressed. The annular segment of the first transmission member 32 is sleeved on the outer periphery of the middle diameter segment and the small diameter segment. The first transmission member 32 includes a first segment and a second segment that are smoothly connected along the axial direction. The inner diameter of the first segment is larger than the inner diameter of the second segment, thereby forming a stepped surface at the connection between the first segment and the second segment. Part of the first segment is sleeved on the outside of the middle diameter segment and part of the first segment is sleeved on the outside of the small diameter segment. The second segment is entirely sleeved on the outside of the small diameter segment, so that there is a certain gap along the axial direction between the middle diameter segment close to the small diameter segment and the stepped surface. This ensures that when the pressing member 332 is pressed, the middle diameter segment of the pressing member 332 will not affect the axial position of the first transmission member 32 and the rotating member 331, thereby realizing the independent action of the pressing member 332 from the rotating member 331.

[0052] In some embodiments, the drive assembly 38 includes a drive member 383, a circuit board 381, and a tactile switch 385. The drive member 383 may be a motor and is provided with a motor pressure plate 384. The tactile switch 385 is located on the circuit board 381 and is electrically connected to the drive member 383. The position of the tactile switch 385 on the circuit board 381 should be aligned with the axial direction of the pressing member 332, so that the tactile switch 385 can abut against the small diameter section of the pressing member 332. Therefore, when the pressing member 332 is pressed, the small diameter section abuts against the tactile switch 385, thereby activating the drive member 383 through the tactile switch 385, and subsequently driving the locking tongue 31 to move via the second transmission member 37 and the first transmission member 32. Preferably, a flexible part 333 for noise reduction can be provided between the small diameter section and the tactile switch 385 to optimize the user experience. The flexible part 333 can be a silicone button, etc. Figure 6 As shown, the Hall element 382 is mounted on the circuit board 381, and the Hall element 382 is located on the edge of the circuit board 381 near the mounting hole 21, so that when the door is closed, the Hall element 382 can approach the magnetic suction assembly 10 and detect the magnetic suction assembly 10, thereby correctly feeding back the door opening and closing status.

[0053] In some embodiments, the lock body assembly 30 further includes a first limiting member 391 for preventing axial movement of the rotating member 331 and the first transmission member 32, and a second limiting member 392 for preventing the pressing member 332 from dislodging from the rotating member 331. The first limiting member 391 and the second limiting member 392 are located at both ends of the first transmission member 32 and respectively limit and cooperate with the rotating member 331 and the pressing member 332, thereby ensuring the stability of the overall structure of the switch assembly 33 and preventing the rotating member 331 and the pressing member 332 from falling off or failing. Specifically, a first groove for installing the first limiting member 391 is provided at the end of the first segment of the annular segment away from the second segment. When the first limiting member 391 is located in the first groove, it can prevent the rotating member 331 from moving away from the housing assembly 40 relative to the annular segment, thereby limiting the rotating member 331 between the first limiting member 391 and the bracket 42. The outer periphery of the first segment of the annular section of the first transmission member 32 is further provided with an annular recess for limiting its position against the bracket 42, thereby restricting the relative axial movement of the first transmission member 32 and the rotating member 331. A second groove for mounting the second limiting member 392 is provided on the smaller diameter segment of the pressing member 332, away from the middle diameter segment. The second groove is positioned relative to the end of the smaller diameter segment of the first transmission member 32 that is further away from the middle diameter segment. When the second limiting member 392 is located within the second groove, it limits the first transmission member 32 to the outer periphery of the pressing member 332, preventing the first transmission member 32 from moving away from the limiting plate relative to the pressing member 332. Thus, through the limiting of the first limiting member 391 and the second limiting member 392, as well as the limiting between the switch assembly 33 and the first transmission member 32 and the bracket 42, an integrated structure of the switch assembly 33 is achieved, enabling the coexistence and independent operation of the rotating member 331 and the pressing member 332. Optionally, both the first and second grooves can be configured as annular grooves, and the first limiting member 391 and the second limiting member 392 can be configured as retaining rings. Compared with the traditional bolt fixing method, the retaining ring fixing method is more reliable and less prone to loosening. Of course, in alternative embodiments not shown, the structure and installation position of the first limiting member 391 and the second limiting member 392 can also be adjusted according to actual needs to adapt to more diverse application scenarios and functional requirements.

[0054] The locking bolt 31 of the lock in this embodiment is driven by both mechanical and electronic means. The mechanical means is achieved by rotating the rotating part 331 to drive the dial wheel, while the electronic means is achieved by pressing the pressing part 332 to start the motor and drive the gear to drive the dial wheel.

[0055] It should be noted that "multiple" in the above embodiments refers to at least two.

[0056] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0057] 1. This solves the problem of poor compatibility of existing locks with door frames of different structures;

[0058] 2. By providing mounting holes on different sides of the snap-fit ​​assembly, the magnetic component can be installed by correspondingly matching the mounting holes on different sides of the snap-fit ​​assembly to fit the door frame structure. In this way, only one magnetic component is needed to ensure the lock's compatibility with door frames of different structures, and at the same time, ensure that the magnetic component can be installed in a position that can fit with other parts of the lock structure. This improves the lock's compatibility and adaptability to door frames of different structures. At the same time, the detachable and switchable nature of the magnetic component can reduce the need for additional magnetic components due to changes in the installation position of the snap-fit ​​assembly, thus saving costs.

[0059] 3. The hook tongue is rotatably connected to the lock tongue through a riveting component, thereby further ensuring the reliability of the lock body assembly and the lock box assembly when locked, while also ensuring the structural stability of the lock body assembly.
