Description

Technical Field

[0001] This invention relates to the field of smart lock technology, and more specifically, to a smart lock body. Background Technology

[0002] The security, convenience, and anti-theft features of smart locks meet the needs of the general public and are being recognized by most users, making them a product of the smart home era.

[0003] Most existing smart locks use motor unlocking and lock cylinder unlocking, while the 6068 standard lock body mostly uses square shaft unlocking and lock cylinder unlocking. This results in an inconsistency in their structural layout, which means that the original door needs to be cut and drilled during installation. For some door frames that are integrated with the door body, the door frame needs to be cut and replaced with a special door strike plate, which affects the integrity and aesthetics of the original door and increases the difficulty of installation.

[0004] In conclusion, how to solve the problems of poor compatibility and difficult installation of smart locks has become an urgent issue for those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a smart lock body to solve the problems of poor compatibility and difficult installation of smart locks for smart door locks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smart lock body includes a lock shell, within which are disposed a main bolt assembly, a flip-lock bolt assembly, and a drive assembly for driving the main bolt assembly and the flip-lock bolt assembly to perform unlocking. The drive assembly includes:

[0008] A drive block is rotatably disposed within the lock housing and includes a first drive end for driving the main bolt assembly to lock and a second drive end for driving the main bolt assembly to unlock. When the drive block moves to the first drive position, the first drive end drives the main bolt assembly to perform a locking action; when the drive block moves to the second drive position, the second drive end drives the main bolt assembly to perform an unlocking action.

[0009] The unlocking block is rotatably disposed within the lock housing to perform locking and unlocking actions on the flip-out latch assembly when it is in a locked state.

[0010] The unlocking paddle is rotatably disposed within the lock housing and includes a first actuating part for cooperating with the second driving end and a second actuating part for cooperating with the unlocking block. When the driving block moves to the second driving position, the second driving end actuates the first actuating part so that the second actuating part actuates the unlocking block to perform an unlocking action.

[0011] Both the motor module and the transmission shaft module are connected to the drive block via a drive transmission component, so that the drive block can be rotated to drive the main locking tongue assembly and the flipping oblique tongue assembly to perform the upper unlocking action;

[0012] The lock cylinder assembly is connected to the unlocking paddle and is used to drive the unlocking paddle to rotate, thereby driving the main bolt assembly and the flipping bolt assembly to perform the unlocking action.

[0013] Optionally, the drive transmission component and the transmission shaft module, as well as the drive transmission component and the motor module, are connected by gear transmission.

[0014] Optionally, the unlocking block is provided with a first engaging portion, and the flipping tongue assembly is provided with a second engaging portion. When the unlocking block is rotated to a first preset position, the first engaging portion engages with the second engaging portion; when the unlocking block is rotated to a second preset position, the first engaging portion disengages from the second engaging portion.

[0015] Optionally, the first latching part is a slot, and the second latching part is a protrusion adapted to the slot; or, the first latching part is a protrusion, and the second latching part is a slot adapted to the protrusion.

[0016] Optionally, the drive assembly further includes a reset mechanism, which includes a reset detection switch and a reset transmission component. The reset detection switch is used to detect whether the drive transmission component is in the initial position. When the drive transmission component is in the initial position, both the main locking tongue assembly and the flipping tongue assembly are in a locked state. The motor module is connected to the drive transmission component through the reset transmission component, so that the motor module can drive the drive transmission component to move to the initial position.

[0017] Optionally, a first elastic reset member is provided on the swing shaft of the unlocking block, the first elastic reset member having a tendency to keep the unlocking block locked to the flipping tongue assembly.

[0018] Optionally, the system also includes a switch paddle assembly, which includes a switch paddle (20), a position switch, and a second elastic reset member. The switch paddle is rotatably mounted on the inner frame of the lock housing. One end of the second elastic reset member is fixed to the lock housing, and the other end is fixed to the switch paddle, for resetting the switch paddle. The position switch is used to detect whether the main bolt assembly is extended to the correct position. When the main bolt assembly is extended to the correct position, the main bolt assembly forces the cam at one end of the switch paddle to rotate and causes the position switch to change state. When the main bolt assembly is retracted, the switch paddle is reset to its initial state by the action of the second elastic reset member.

[0019] Optionally, the flipping tongue assembly includes:

[0020] The latch module includes a latch root located inside the lock housing and a latch body connected to the latch root and protruding from the lock housing under normal conditions.

[0021] A slanted latch guide rod is disposed inside the lock housing and slides in cooperation with the inner skeleton of the lock housing along the axial direction of the slanted latch guide rod. The proximal end of the slanted latch guide rod is connected to the root of the latch. Pulling the slanted latch body can drive the slanted latch guide rod to slide towards the outside of the side strip. When the entire slanted latch module moves to the outside of the side strip, the slanted latch module can rotate at least 180° around the axis where the slanted latch guide rod is located.

[0022] The third elastic reset component is disposed on the inner frame and has an elastic reset end. The elastic reset end can contact the oblique tongue guide rod and has a tendency to keep the oblique tongue guide rod in a preset working position.

[0023] Optionally, the flip-up latch assembly further includes a reversing locking member disposed within the lock housing and a driving part located outside the lock housing. The inner frame includes a guide fixing plate arranged near the distal end of the latch guide rod. The latch guide rod passes through the guide fixing plate. A limit stop is provided at the distal end of the latch guide rod. A first opening groove adapted to the limit stop is provided on the guide fixing plate. The reversing locking member is disposed between the limit stop and the guide fixing plate. The driving part can drive the reversing locking member to switch between a locking position and a reversing position.

[0024] When the reversing locking member is in the locked position, the reversing locking member blocks the limiting stop from passing through the first opening slot; when the reversing locking member is in the reversing position, the reversing locking member avoids the limiting stop from passing through the first opening slot.

[0025] Optionally, the inner frame further includes a tongue limiting plate arranged near the side strip. The tongue limiting plate includes a guide support plate arranged opposite to the guide fixing plate and a limiting guard plate for cooperating with two opposite sides of the tongue root. The tongue guide rod passes through the guide support plate.

[0026] Optionally, the third elastic reset member is a compression spring sleeved on the oblique tongue guide rod. The compression spring is located between the guide fixing plate and the guide support plate and has a first compression end and a second compression end. A radial protrusion is provided on the rod body near the oblique tongue guide rod, and a second opening groove adapted to the radial protrusion is provided on the guide support plate.

[0027] Under normal conditions, the guide fixing plate abuts against the first compression end, and the guide support plate abuts against the second compression end;

[0028] When the limiting stop passes through the first opening groove, the limiting stop abuts against the first compression end; when the oblique tongue retracts towards the inside of the side strip, the axial end of the radial protrusion passes through the second opening groove and contacts and abuts against the second compression end.

[0029] Optionally, both the front and back of the lock housing are sealed plates, and the mounting holes and grooves on the sealed plates are tightly connected to the corresponding mating parts.

[0030] Optionally, the dimensions and layout of the smart lock body are the same as those of the 6068 standard lock body.

[0031] Compared to the background technology description, the aforementioned smart lock body includes a lock shell, within which are arranged a main bolt assembly, a flip-lock bolt assembly, and a drive assembly for driving the main bolt assembly and the flip-lock bolt assembly to perform locking and unlocking actions. The drive assembly includes a drive block, an unlocking block, an unlocking paddle, a motor module, a transmission shaft module, and a lock cylinder assembly. The drive block is rotatably disposed within the lock shell and includes a first drive end for locking the main bolt assembly and a second drive end for unlocking the main bolt assembly. When the drive block moves to the first drive position, the first drive end drives the main bolt assembly to perform a locking action; when the drive block moves to the second drive position, the second drive end drives the main bolt assembly to perform an unlocking action; the unlocking block is rotatably disposed within the lock shell. The locking mechanism is housed within the lock housing to perform locking and unlocking actions on the flip-lock bolt assembly, which is in a locked state. The unlocking paddle is rotatably mounted within the lock housing and includes a first actuating part for engaging with the second drive end and a second actuating part for engaging with the unlocking block. When the drive block moves to the second drive position, the second drive end actuates the first actuating part, causing the second actuating part to move the unlocking block to perform the unlocking action. The motor module and drive shaft module are both connected to the drive block via drive transmission components, so that by driving the drive block to rotate, they drive the main lock bolt assembly and the flip-lock bolt assembly to perform the upper unlocking action. The lock cylinder assembly is connected to the unlocking paddle to drive the unlocking paddle to rotate, thereby driving the main lock bolt assembly and the flip-lock bolt assembly to perform the unlocking action. In practical applications, the smart lock body utilizes a motor module that drives a drive block to rotate via a drive transmission component. When the drive block reaches the first drive position, the first drive end drives the main bolt assembly to perform a locking action. When the drive block reaches the second drive position, the second drive end drives the main bolt assembly to perform an unlocking action, and also drives the unlocking lever to move the unlocking block to perform an unlocking action, thereby realizing the unlocking operation of the motor module. The transmission shaft module, through a drive transmission component, drives the drive block to rotate, which can also realize the locking operation of the main bolt assembly and the unlocking operation of the main bolt assembly and the flip-lock bolt assembly. The transmission process is the same as that of the motor module in performing the unlocking operation. The lock cylinder assembly, through the rotation of the key, drives the unlocking lever to rotate. Since the unlocking lever includes a first actuating part for cooperating with the second drive end and a second actuating part for cooperating with the unlocking block, the rotation of the unlocking lever can drive the main bolt assembly and the flip-lock bolt assembly to perform an unlocking action. This smart lock body, through the above-mentioned arrangement, can achieve independent unlocking of the motor module, drive shaft module, and lock cylinder assembly. It includes the unlocking method of the 6068 standard lock body, so it can be adapted to the door body corresponding to the 6068 standard lock body. During the installation process, there is no need to cut or drill the door panel, which greatly improves the compatibility of the smart lock and greatly reduces the installation difficulty.

Detailed Implementation

[0040] The core of this invention lies in providing an intelligent lock body to solve the problems of poor compatibility and difficult installation of intelligent locks for smart door locks.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Reference Figure 1 and Figure 2 This invention provides a smart lock body, including a lock shell 31. The lock shell 31 houses a main bolt assembly 1, a flip-lock bolt assembly, and a drive assembly for driving the main bolt assembly 1 and the flip-lock bolt assembly to perform locking and unlocking actions. The drive assembly includes a drive block 17, an unlocking block 13, an unlocking paddle 24, a motor module 14, a transmission shaft module 15, and a lock cylinder assembly 23. The drive block 17 is rotatably disposed within the lock shell 31 and includes a first drive end 171 for locking the main bolt assembly 1 and a second drive end 172 for unlocking the main bolt assembly 1. When the drive block 17 moves to the first drive position, the first drive end 171 drives the main bolt assembly 1 to perform a locking action; when the drive block 17 moves to the second drive position, the second drive end 172 drives the main bolt assembly 1 to perform an unlocking action. The unlocking block 13 is rotatably disposed within the lock shell 31. The lock housing 31 is configured to perform locking and unlocking actions on the flip-lock bolt assembly in the locked state. The unlocking lever 24 is rotatably disposed in the lock housing 31 and includes a first actuating part 241 for cooperating with the second drive end 172 and a second actuating part 242 for cooperating with the unlocking block 13. When the drive block 17 moves to the second drive position, the second drive end 172 actuates the first actuating part 241, so that the second actuating part 242 actuates the unlocking block to perform the unlocking action. The motor module 14 and the transmission shaft module 15 are both connected to the drive block 17 via the drive transmission component 16, so as to drive the main lock bolt assembly 1 and the flip-lock bolt assembly to perform the upper unlocking action by driving the drive block 17 to rotate. The lock cylinder assembly 23 is connected to the unlocking lever 24 to drive the unlocking lever 24 to rotate, so as to drive the main lock bolt assembly 1 and the flip-lock bolt assembly to perform the unlocking action.

[0043] In practical applications, the smart lock body utilizes a motor module that drives a drive block to rotate via a drive transmission component. When the drive block reaches the first drive position, the first drive end drives the main bolt assembly to perform a locking action. When the drive block reaches the second drive position, the second drive end drives the main bolt assembly to perform an unlocking action, and also drives the unlocking lever to move the unlocking block to perform an unlocking action, thereby realizing the unlocking operation of the motor module. The transmission shaft module, through a drive transmission component, drives the drive block to rotate, which can also realize the locking operation of the main bolt assembly and the unlocking operation of the main bolt assembly and the flip-lock bolt assembly. The transmission process is the same as that of the motor module in performing the unlocking operation. The lock cylinder assembly, through the rotation of the key, drives the unlocking lever to rotate. Since the unlocking lever includes a first actuating part for cooperating with the second drive end and a second actuating part for cooperating with the unlocking block, the rotation of the unlocking lever can drive the main bolt assembly and the flip-lock bolt assembly to perform an unlocking action. This smart lock body, through the above-mentioned arrangement, can achieve independent unlocking of the motor module, drive shaft module, and lock cylinder assembly. It includes the unlocking method of the 6068 standard lock body, so it can be adapted to the door body corresponding to the 6068 standard lock body. During the installation process, there is no need to cut or drill the door panel, which greatly improves the compatibility of the smart lock and greatly reduces the installation difficulty.

[0044] In some specific implementations, the drive transmission component 16 and the drive shaft module 15, as well as the drive transmission component 16 and the motor module 14, can be connected via gear transmission. Specifically, the drive transmission component 16 can be designed as a gear structure, and the output end of the motor module 14 can be equipped with a transmission gear that meshes with this gear structure. Similarly, the drive shaft module 15 can be a square shaft, with a transmission gear coaxially arranged on the square shaft that meshes with the aforementioned gear structure. By designing it as a gear transmission, the transmission becomes more stable, precise, and reliable. Of course, it is understood that in practical applications, other transmission methods commonly used by those skilled in the art can also be used, such as the structure of a transmission belt or transmission chain, which are not further limited here.

[0045] In some specific implementations, the unlocking block 13 may be provided with a first engaging portion, and the flip-hinged tongue assembly may be provided with a second engaging portion. When the unlocking block 13 rotates to a first preset position, the first engaging portion engages with the second engaging portion; when the unlocking block 13 rotates to a second preset position, the first engaging portion disengages from the second engaging portion. By using the engagement of the first and second engaging portions to control the locking and unlocking of the flip-hinged tongue assembly in a locked state, the structure is simpler and easier to implement.

[0046] In a further implementation, the first snap-fit ​​portion can be specifically designed as a slot, and the second snap-fit ​​portion can be specifically designed as a protrusion that matches the slot; of course, it is understood that in actual application, the first snap-fit ​​portion can also be designed as a protrusion, and the second snap-fit ​​portion can be designed as a slot that matches the protrusion.

[0047] In some more specific embodiments, a first elastic reset member 11 may also be provided on the swing shaft of the unlocking block 13. The first elastic reset member 11 has a tendency to keep the unlocking block 13 locked to the flip-up tongue assembly. The first elastic reset member 11 makes the unlocking block 13 have a tendency to remain in the locked position. Specifically, the first elastic reset member 11 may be an elastic torsion spring sleeved on the swing shaft, or other elastic reset structures commonly used by those skilled in the art, without further specific limitations.

[0048] In some other specific implementations, the aforementioned drive assembly further includes a reset mechanism. This reset mechanism may specifically include a reset detection switch 19 and a reset transmission component 18. The reset detection switch 19 detects whether the drive transmission component 16 is in its initial position. When the drive transmission component 16 is in its initial position, both the main latch assembly 1 and the flip latch assembly are in a locked state. The motor module 14 is connected to the drive transmission component 16 via the reset transmission component 18, enabling the motor module 14 to drive the drive transmission component 16 to its initial position. Through this reset mechanism, the motor module 14 can automatically reset to the locked state via internal control logic after each unlocking operation, ensuring the security of the smart lock body.

[0049] In some other specific implementations, the aforementioned smart lock body may further include a switch paddle assembly. The switch paddle assembly includes a switch paddle 20, a position switch 21, and a second elastic reset member 22. The switch paddle 20 is rotatably mounted on the inner frame of the lock housing 31 and can rotate around its axis. One end of the second elastic reset member 22 is fixed to the lock housing 31, and the other end is fixed to the switch paddle 20, used for resetting the switch paddle 20. The position switch 21 is used to detect whether the main bolt assembly 1 has extended to its full position. When the main bolt assembly 1 extends to its full position, it forces the cam at one end of the switch paddle 20 to rotate, causing the position switch 21 to change state. When the main bolt assembly 1 retracts, the switch paddle 20 is reset to its initial state by the action of the second elastic reset member 22. This switch paddle assembly allows for more accurate knowledge of the current state of the main bolt assembly 1, thereby making the entire smart lock more secure.

[0050] In some more specific implementation plans, refer to Figure 1 Combination Figures 3-5The aforementioned flip-up latch assembly may specifically include a latch module 2, a latch guide rod 5, and a third elastic reset member 6. The latch module 2 includes a latch root 2a located inside the lock housing 31 and a latch body 2b connected to the latch root 2a and protruding from the side strip 30 of the lock housing 31 in normal operation. The latch guide rod 5 is disposed inside the lock housing 1 and slides in cooperation with the inner frame 32 of the lock housing 31 along the axial direction of the latch guide rod 5. The proximal end of the latch guide rod 5 is connected to the latch root 2a. Pulling the latch body 2b can drive the latch guide rod 5 to slide towards the outside of the side strip 30. When the latch module 2 is fully moved to the outside of the side strip 30, the latch module 2 can rotate at least 180° around the axis where the latch guide rod 5 is located. The third elastic reset member 6 is disposed in the inner frame 32 and has an elastic reset end. The elastic reset end can contact the latch guide rod 5 and has a tendency to keep the latch guide rod 5 in a preset working position.

[0051] In practical applications, by designing the flip-up latch assembly into the above-mentioned structural form, when the latch module 2 needs to be reversed, only the latch body 2b needs to be pulled, which in turn drives the latch guide rod 5 to slide towards the outside of the side strip 30. When the latch module 2 has moved completely to the outside of the side strip 30, the latch module 2 can rotate 180° around the axis where the latch guide rod 5 is located. Then, the latch body 2b is released, and under the action of the third elastic reset member 6, the latch guide rod 5 is pulled back to the preset working position. At this time, the latch module 2 completes the reversing operation. The operation is very simple and convenient. It can not only adapt to the left-opening and right-opening door arrangement, but also avoids the problem of cumbersome latch reversing operation of the lock body.

[0052] It should be noted that the aforementioned tongue-and-slip module 2 can rotate around the axis of the tongue-and-slip guide rod 5. This can be achieved by the tongue-and-slip module 2 and the tongue-and-slip guide rod 5 rotating as a whole around the axis of the tongue-and-slip guide rod 5; alternatively, the root of the tongue-and-slip module 2 can be rotatably connected to the proximal end of the tongue-and-slip guide rod 5, allowing the tongue-and-slip module 2 to rotate without the tongue-and-slip guide rod 5 needing to rotate. This latter method requires an additional rotating connection structure. In practical applications, the design can be chosen based on actual needs, and no further specific limitations are made here. Additionally, it should be noted that the proximal end of the tongue-and-slip guide rod 5 refers to the end of the tongue-and-slip guide rod 5 facing the side strip 30, and the distal end of the tongue-and-slip guide rod 5 refers to the end of the tongue-and-slip guide rod 5 away from the side strip 30.

[0053] In a further embodiment, the aforementioned flip-up latch assembly may further include a reversing locking member 9 disposed within the lock housing 31 and a driving part 33 located outside the lock housing 31. The inner frame 32 includes a guide fixing plate 10 arranged near the distal end of the latch guide rod 5. The latch guide rod 5 passes through the guide fixing plate 10, and a limit stop 8 is provided at the distal end of the latch guide rod 5. A first opening groove 101 adapted to the limit stop 8 is provided on the guide fixing plate 10. The reversing locking member 9 is disposed between the limit stop 8 and the guide fixing plate 10. The driving part can drive the reversing locking member 9 to switch between a locked position and a reversing position. When the reversing locking member 9 is in the locked position, the reversing locking member 9 blocks the limit stop 8 from passing through the first opening groove 101. When the reversing locking member 9 is in the reversing position, the reversing locking member 9 avoids the limit stop 8 passing through the first opening groove 101. By setting the reversing locking member 9 and the driving part 33, the flipping tongue assembly is controllable when performing reversing. The reversing operation can only be performed when the reversing locking member 9 is driven to the reversing position, thus avoiding user misoperation.

[0054] In a further embodiment, the aforementioned inner frame 32 may also include a tongue limiting plate 321 arranged near the side strip 30. The tongue limiting plate 321 includes a guide support plate 3211 arranged opposite to the guide fixing plate 10 and a limiting guard plate 3212 for engaging with two opposite sides of the tongue root 2a. The tongue guide rod 5 passes through the guide support plate 3211. By designing the tongue limiting plate 321, the sliding guidance of the tongue guide rod 5 can be enhanced on the one hand, and the tongue root of the tongue module 2 in the working state can be limited to avoid unnecessary shaking. In addition, the tongue limiting plate 321 also has the function of blocking the passage of the limiting stop 8, thereby preventing the tongue guide rod 5 from being completely pulled out.

[0055] In some more specific embodiments, the aforementioned third elastic reset member 6 is a compression spring sleeved on the oblique tongue guide rod 5. The compression spring is located between the guide fixing plate 10 and the guide support plate 3211 and has a first compression end and a second compression end. A radial protrusion 51 is provided on the rod body near the end of the oblique tongue guide rod 5, and a second opening groove 32111 adapted to the radial protrusion 51 is provided on the guide support plate 3211. Under normal conditions, the guide fixing plate 10 abuts against the first compression end, and the guide support plate 3211 abuts against the second compression end. When the oblique tongue assembly is flipped to perform a reversing operation, the reversing lock member 9 is opened to the reversing position, and then the oblique tongue is pulled. As the tongue 2b moves outward toward the side strip 30, the limiting stop 8 passes through the first opening groove 101. After passing through the first opening groove 101, the limiting stop 8 abuts against the first compression end and continues to compress the first compression end. When the tongue module 2 is completely pulled away from the side strip 30 and completes a 180-degree rotation, after releasing the tongue 2b, the tongue guide rod 5 can be pulled back under the reset action of the first compression end against the limiting stop 8. At this time, the limiting stop 8 is located in the first opening groove 101. The tongue 2b is manually pushed inward toward the side strip 30, and at the same time, the reversing locking member 9 is driven to the locking position by the driving part 33 to complete the installation after reversing. Furthermore, under normal conditions (i.e., during normal operation), when the tongue module 2b is subjected to external pressure and retracts towards the inside of the side strip 30, the axial end of the radial protrusion 51 passes through the second opening groove 32111 and contacts and abuts against the second compression end. As the tongue module 2b retracts, it compresses the second compression end, which then has an elastic tendency to restore the tongue module 2b to its extended working state. In the above structure, only one compression spring is needed to achieve the pull-back force when the tongue module 2 is pulled out and the outward elastic effect after the tongue module 2b retracts, making the structure simpler. It is understood that the above structural form is merely an example of an embodiment of the present invention. In actual applications, other elastic reset member structures can be designed, such as a spring sheet or multiple elastic members working together; no further specific limitations are made here.

[0056] In some specific implementation schemes, for ease of installation, the lock housing 31 can be formed by splicing two opposing shell walls together, and after splicing, it can be locked and fixed by fasteners.

[0057] In some other specific implementations, the front and back of the lock housing 31 can both be designed as sealed plates, with the mounting holes and grooves on the sealed plates tightly connected to the corresponding mating parts. By designing the lock body structure as described above, since the front and back of the lock housing 31 are both sealed plates, and the mounting holes and grooves on the sealed plates are tightly connected to the corresponding mating parts, the lock housing 31 has no exposed parts. After the entire machine is assembled, the internal structural components of the lock body are isolated from the outside, and internal sound can only escape through the mating gaps, greatly reducing the noise of the lock body.

[0058] In a further embodiment, the mounting holes and grooves on the sealing plate housing may specifically include plate housing positioning holes, and the mating component corresponding to the plate housing positioning holes is specifically a positioning post module 7. The positioning post module 7 and the plate housing positioning holes can be sealed together by a sealing kit. By designing a sealing kit, the tightness of the fit between the positioning post module 7 and the plate housing positioning holes can be further ensured, which helps to improve the noise reduction effect.

[0059] In a further embodiment, a sound-absorbing pad can be provided on the tongue surface of the aforementioned tongue module 2. By designing a sound-absorbing pad, noise generated by direct collision between the metal tongue and the metal door frame can be avoided, thereby helping to improve the noise reduction effect.

[0060] It should be noted that the sound-absorbing pad can be made of wear-resistant plastic or other sound-absorbing materials commonly used by those skilled in the art; no further specific limitations are made here.

[0061] In some specific implementations, the edges of the main latch assembly 1 and the main latch frame of the side strip 30 of the lock housing 31 can all be designed with a clearance fit. At least one of the sliding contact surfaces of the main latch assembly 1 and the inner frame is made of a sound-absorbing material. By designing this structure, since the edges of the main latch assembly 1 and the main latch frame of the side strip 30 of the lock housing 31 are with a clearance fit, the internal fit prevents the latch body of the main latch assembly 1 from directly scraping against the side strip 30, thus avoiding noise. Simultaneously, since at least one of the sliding contact surfaces of the main latch assembly 1 and the inner frame is made of a sound-absorbing material, direct metal-to-metal contact between the main latch assembly 1 and the inner frame is avoided, further reducing noise.

[0062] In a further embodiment, the sliding engagement between the main bolt assembly 1 and the inner frame 32 of the lock housing 31 is achieved by the main bolt assembly 1 having a guide structure. Specifically, this structure may include a first guide sleeve rivet 25 supported on the lower side of the main bolt assembly 1 and a first guide sleeve 26 fitted onto the first guide sleeve rivet 25; and a second guide sleeve rivet 29 supported in the middle groove of the main bolt assembly 1 and a second guide sleeve 28 fitted onto the second guide sleeve rivet 29. Both the first guide sleeve 26 and the second guide sleeve 28 are made of sound-absorbing material. This arrangement reduces noise and changes the sliding motion to rolling motion, reducing frictional resistance and making the sliding smoother.

[0063] It should be noted that the first guide sleeve 26 and the second guide sleeve 28 can be plastic rollers or other sound-absorbing materials known to those skilled in the art, without further specific limitations.

[0064] In some more specific implementations, the dimensions and layout of the aforementioned smart lock body are preferably designed to be the same as those of the 6068 standard lock body. This allows the smart lock body to be used on doors where a 6068 standard lock body has been installed.
