Description

Technical Field

[0001] This application relates to the field of lock body structure technology, specifically to lock bodies, smart locks, and doors. Background Technology

[0002] Smart locks are locks that are more intelligent in terms of user identification, security, and management, unlike traditional mechanical locks. They are usually equipped with components such as sensors and chips, and have functions such as password recognition, fingerprint recognition, and remote control via mobile phone software.

[0003] In related technologies, the lock body is the main part of a smart lock, including the bolt, bolt drive mechanism, lock cylinder mounting hole, and other structures. The main function of the lock body is to receive the drive of the key or motor and drive the bolt to move through the internal transmission mechanism, thereby realizing the locking and unlocking of the door.

[0004] However, after the latch extends and the door is locked, if the motor jams or loses power and cannot rotate, the handle on the inside of the door will also be jammed because the motor usually uses a worm gear transmission method, which is irreversible. This prevents the door from being opened. Summary of the Invention

[0005] This application provides a lock body, a smart lock, and a door, enabling the smart lock to be unlocked via a handle even when the motor is not running.

[0006] On the one hand, this application provides a lock body, including a lock shell, a rotating assembly, a paddle assembly, a bolt assembly, a handle paddle, and an elastic element, the specific solution of which is as follows.

[0007] A rotating assembly is reciprocated within the lock housing about a first axis and is suitable for connection with a motor drive. The first end of the rotating assembly is provided with a first snap-fit ​​part.

[0008] A paddle assembly is reciprocatingly disposed within the lock housing around the first axis, and the paddle assembly is provided with a second locking part and a drive gear part;

[0009] The latch assembly is slidably disposed within the lock housing and is connected to the paddle assembly in a driving manner;

[0010] A handle paddle, which is rotatably disposed within the lock housing and adapted to be connected to the handle via a drive mechanism, and is connected to the drive gear unit via a drive mechanism;

[0011] The elastic element, under the force of the elastic element, causes the first locking part to engage with the second locking part of the rotating assembly;

[0012] When the unlocking force applied by the handle paddle to the drive gear is greater than a preset value, the first locking part disengages from the second locking part, causing at least the first end of the rotating assembly to move radially.

[0013] Beneficial effects: By setting a reciprocating rotating assembly and a lever assembly inside the lock housing, under the force of the elastic element, the first locking part at the first end of the rotating assembly engages with the second locking part on the lever assembly. Thus, when the lock body is locked and the motor inside the lock body is jammed, a person inside the door can apply a large unlocking force to the handle, causing the unlocking force applied by the lever to the lever assembly to exceed a preset value. This deforms the elastic element, causing the first and second locking parts to disengage, at least causing the first end of the rotating assembly to move radially. The first and second locking parts are disconnected from the transmission connection, preventing the motor from locking the lever assembly. At the same time, since the bolt assembly and the lever assembly are connected, a person inside the door can directly unlock the door by using the handle, causing the bolt assembly to retract into the lock housing, thus achieving unlocking from the inside.

[0014] In one optional embodiment, the lock housing is provided with a first slide groove and a second slide groove, both of which are arc-shaped grooves, and the central axis of the first slide groove and the central axis of the second slide groove coincide with the first axis.

[0015] The second end of the rotating component is provided with a slider, which is slidably connected to the first slide groove, and the rotating component can rotate around the slider;

[0016] The paddle assembly is provided with an arc-shaped block, which is adapted to slide and connect with the second slide groove.

[0017] In one optional embodiment, the rotating component is provided with an arc-shaped oval groove, and a notch is provided on any arc-shaped side of the arc-shaped oval groove. A guide surface is provided on the notch, and the notch is the first snap-fit ​​part.

[0018] The paddle assembly is provided with a locking block, which is the second locking part; the locking block is located in the arc-shaped oval groove and is adapted to lock into the notch;

[0019] When the unlocking force applied by the handle paddle to the drive gear is greater than a preset value, the rotating assembly can move radially relative to the paddle assembly under the guidance of the guide surface.

[0020] In one alternative implementation, the notch is located on the arcuate edge away from the first axis; the elastic element causes the rotating assembly to tend toward the first axis.

[0021] In an optional embodiment, a drive shaft is further included. The drive shaft is rotatably disposed within the lock housing about the first axis. The drive shaft is provided with a drive hole and a drive part. The drive hole is adapted to be sleeved with the output shaft of the motor. The drive part is capable of driving contact with both ends of the rotating assembly along the rotation direction of the rotating assembly to drive the rotating assembly to reciprocate.

[0022] In one optional embodiment, the latch assembly includes a main latch component, which is slidably disposed within the lock housing. The main latch component is provided with a drive groove, and the two edges of the opening of the drive groove are beveled to form an anti-retraction part and an anti-extension part, respectively.

[0023] The paddle assembly is provided with a paddle head, which is located in the drive groove to drive the main locking tongue component to reciprocate and slide.

[0024] When the main bolt component is retracted into the lock housing, the dial rotates out from the drive groove and abuts against the anti-extension part to prevent the main bolt component from sliding out of the lock housing;

[0025] With the main bolt component extended outside the lock housing, the dial rotates out of the drive groove and abuts against the anti-retraction part to prevent the main bolt component from retracting into the lock housing.

[0026] In one optional embodiment, a force-receiving push plate is further included, the force-receiving push plate being located inside the lock housing, and a first end of the force-receiving push plate being rotatably connected to the lock housing;

[0027] The main bolt component is provided with a connecting guide groove and a limiting groove. The second end of the force-bearing push plate is slidably disposed in the guide groove and can enter the limiting groove after the main bolt component extends out of the lock body, so as to prevent the main bolt component from moving into the lock shell.

[0028] In one optional embodiment, a limiting gear is further included. The limiting gear is rotatably disposed within the lock housing and is connected to the paddle assembly. The limiting gear is provided with a limiting part. The lower part of the limiting groove communicates with the guide groove. The limiting part can push the second end of the force-bearing push plate into and confine it within the limiting groove during the extension of the main lock tongue component.

[0029] Secondly, this application also provides a smart lock, including: a lock body as described in any of the embodiments of the first aspect.

[0030] Beneficial effects: Since smart locks include a lock body, they have the same effects as lock bodies, which will not be elaborated here.

[0031] Thirdly, this application also provides a door, including: a lock body as described in any of the embodiments of the first aspect, or a smart lock as described in the second aspect.

[0032] Beneficial effects: Since the door includes a lock body or smart lock, it has the same effect as the lock body or smart lock, which will not be elaborated here. Attached Figure Description

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] In related technologies, the lock body is the main part of a smart lock, including the bolt, bolt drive mechanism, lock cylinder mounting hole, and other structures. The main function of the lock body is to receive the drive of the key or motor and drive the bolt to move through the internal transmission mechanism, thereby realizing the locking and unlocking of the door.

[0059] However, after the latch extends and the door is locked, if the motor jams or loses power and cannot rotate, the handle on the inside of the door will also be jammed because the motor usually uses a worm gear transmission method, which is irreversible. This prevents the door from being opened.

[0060] To address the aforementioned technical problems, this application provides a lock body, a smart lock, and a door, enabling the smart lock to be unlocked via a handle even when the motor is not functioning.

[0061] The following combination Figures 1 to 12 This describes an embodiment of the present application.

[0062] According to embodiments of this application, in one aspect, a lock body is provided, such as... Figures 1 to 10 As shown, it includes a lock housing 1, a rotating assembly 2, a paddle assembly 3, a handle paddle 5, and an elastic element 6, with the specific design as follows.

[0063] Lock case 1 is a metal shell, which usually consists of two slots that are connected by rivets or bolts.

[0064] like Figure 5 As shown, the rotating assembly 2 is disposed within the lock housing 1, reciprocating around the first axis X. Specifically, the first axis X is as follows: Figure 5 As shown; the rotation trajectory of the rotating component 2 is an arc; the rotating component 2 is suitable for transmission connection with the motor through an intermediate transmission component or a connection, and the first end of the rotating component 2 is provided with a first snap-fit ​​part 21.

[0065] like Figure 5 As shown, the paddle assembly 3 is reciprocating around the first axis X inside the lock housing 1. Specifically, the reciprocating rotation trajectory of the paddle assembly 3 is an arc. The paddle assembly 3 is provided with a second locking part 31 and a drive gear part 32.

[0066] The latch assembly 4 is slidably disposed within the lock housing 1 and is connected to the paddle assembly 3 in a transmission manner; specifically, the latch assembly 4 includes a main latch component 41, a slanted latch component, etc.

[0067] It should be noted that the above-mentioned "lock tongue assembly 4 is slidably disposed in the lock housing 1 and is drivenly connected to the paddle assembly 3" means that the lock tongue assembly can be directly driven to the paddle assembly 3, or it can be driven through other driving intermediate components.

[0068] As shown in Figure 5, the handle paddle 5 is rotatably disposed inside the lock housing 1, and is suitable for transmission connection with the handle through a spline or irregular cross-section shaft hole. The handle paddle 5 is also transmission connected to the drive gear part 32.

[0069] like Figure 5As shown, the elastic element 6 is specifically a spring or a rubber body with a certain elastic expansion and contraction; under the action of the elastic element 6, the first locking part 21 and the second locking part 31 of the rotating assembly 2 are engaged.

[0070] When the unlocking force applied by the handle paddle 5 to the drive gear 32 is greater than a preset value, the first locking part 21 disengages from the second locking part 31, causing at least the first end of the rotating assembly 2 to move radially.

[0071] It should be noted that during the normal unlocking and locking process of the lock body, the elastic force applied by the elastic element 6 to the rotating assembly 2 can keep the first locking part 21 and the second locking part 31 in a locked state, that is, the rotating assembly 2 and the paddle assembly 3 rotate synchronously.

[0072] In specific usage, such as Figures 5 to 6 As shown, after the bolt assembly 4 of the lock body extends out of the lock body to perform the locking action, if the motor of the lock body jams due to reasons such as power failure, a person located on the inside of the door can apply a greater unlocking force to the handle, causing the handle lever 5 to apply an unlocking force greater than the preset value to the lever assembly 3. Figure 6 and Figure 8 As shown, the elastic element 6 deforms, the first locking part 21 and the second locking part 31 disengage, at least causing the first end of the rotating component 2 to move radially, the first locking part 21 and the second locking part 31 to disconnect the transmission connection, preventing the motor from locking the paddle assembly 3, and allowing the person inside the door to directly unlock the door through the handle.

[0073] In this embodiment, such as Figures 1 to 10 As shown, by setting a reciprocating rotating assembly 2 and a lever assembly 3 inside the lock housing 1, under the force of the elastic member 6, the first locking part 21 at the first end of the rotating assembly 2 engages with the second locking part 31 on the lever assembly 3. Thus, when the lock body is locked and the motor inside the lock body is jammed, a person inside the door can apply a large unlocking force to the handle, causing the unlocking force applied by the lever 5 to the lever assembly 3 to be greater than a preset value. The elastic member 6 deforms, and the first locking part 21 and the second locking part 31 disengage, at least causing the first end of the rotating assembly 2 to move radially. The first locking part 21 and the second locking part 31 are disconnected from the transmission connection, preventing the motor from locking the lever assembly 3. At the same time, since the bolt assembly 4 is connected to the lever assembly 3, a person inside the door can directly perform the unlocking action through the handle, causing the bolt assembly 4 to retract into the lock housing 1, thereby realizing unlocking from the inside of the door.

[0074] In one embodiment, such as Figure 4As shown, the lock housing 1 is provided with a first slide groove 11 and a second slide groove 12. Specifically, the first slide groove 11 is provided in pairs on two opposite surfaces of the lock housing 1, and the second slide groove 12 is provided in pairs on two opposite sides of the lock housing 1. Both the first slide groove 11 and the second slide groove 12 are arc-shaped grooves, and the central axis of the first slide groove 11 and the central axis of the second slide groove 12 coincide with the first axis X. The radius of the first slide groove 11 and the radius of the second slide groove 12 can be set according to actual needs.

[0075] like Figure 7 , Figure 8 and Figure 10 As shown, the second end of the rotating component 2 is provided with a slider 22, which is slidably connected to the first slide groove 11. The rotating component 2 can rotate around the slider 22. Specifically, the slider 22 can be cylindrical, and the two ends of the slider 22 are slidably connected to the two first slide grooves 11 on the lock housing 1, and the rotating component 2 can rotate around the axis of the slider 22.

[0076] like Figure 7 , Figure 8 and Figure 9 As shown, the paddle assembly 3 is provided with an arc-shaped block 33 to prevent the paddle assembly 3 from rotating. The arc-shaped block 33 is adapted to slide and connect with the second slide groove 12. Specifically, the radius of the arc-shaped block 33 is the same as the radius of the second slide groove 12, and the two ends of the arc-shaped block 33 are respectively slidably connected to the two second slide grooves 12 on the lock housing 1.

[0077] In actual use, after the bolt assembly 4 of the lock body extends out of the lock body to perform the locking action, if the motor of the lock body jams due to reasons such as power failure, a person located on the inside of the door can apply a large unlocking force to the handle, causing the handle lever 5 to apply an unlocking force greater than the preset value to the lever assembly 3, thus deforming the elastic element 6. Figure 6 and Figure 8 As shown, the first locking part 21 disengages from the second locking part 31, the rotating component 2 rotates around the axis of its slider 22, and the paddle assembly 3 can rotate relative to the rotating component 2 in the second slide groove 12 to realize the transmission cut-off between the rotating component 2 and the paddle assembly 3; this facilitates the person inside the door to unlock the door through the handle; after unlocking, the handle is reset, thereby the second locking part 31 is reset and re-engages with the first locking part 21 under the action of the elastic member 6.

[0078] In some embodiments not shown, the lock housing 1 is provided with a first slide groove 11 and a second slide groove 12. Specifically, the first slide groove 11 is provided in pairs on two opposite surfaces of the lock housing 1, and the second slide groove 12 is provided in pairs on two opposite sides of the lock housing 1. Both the first slide groove 11 and the second slide groove 12 are arc-shaped grooves, and the central axis of the first slide groove 11 and the central axis of the second slide groove 12 coincide with the first axis X. Specifically, the radius of the first slide groove 11 and the radius of the second slide groove 12 can be set according to actual needs.

[0079] The second end of the rotating component 2 is provided with a slider 22. The slider 22 is arc-shaped, but the thickness of the slider 22 along the radial direction of the rotation trajectory of the rotating component 2 is less than the width of the first groove 11 along its radial direction. Thus, the rotating component 2 can reciprocate along the radial direction of the first groove 11 under the action of the elastic member 6.

[0080] Specifically, the elastic element 6 is fixed on the rotating assembly 2, and an arc-shaped limiting plate is provided in the lock body. The central axis of the arc-shaped limiting plate coincides with the first axis X. Rollers or balls are provided at the end of the elastic element 6 that contacts the arc-shaped limiting plate to reduce the sliding friction between the elastic element 6 and the arc-shaped limiting plate. More specifically, there can be multiple elastic elements 6, which are evenly distributed between the rotating assembly 2 and the arc-shaped limiting plate.

[0081] It is worth noting that the radius of the arc plate can be smaller than the radius of the first slide groove 11, so that the arc-shaped limiting plate is set between the first axis X and the rotating component 2; of course, the radius of the arc plate can be larger than the radius of the first slide groove 11, so that the arc-shaped limiting plate is located on the side of the rotating component 2 away from the first axis X.

[0082] The paddle assembly 3 is provided with an arc-shaped block 33 to prevent the paddle assembly 3 from rotating. The arc-shaped block 33 is adapted to slide and connect with the second slide groove 12. Specifically, the radius of the arc-shaped block 33 is the same as the radius of the second slide groove 12, and the two ends of the arc-shaped block 33 are respectively slidably connected to the two second slide grooves 12 on the lock housing 1.

[0083] In this embodiment, the thickness of the slider 22 along the radial path of the rotating assembly 2 is less than the width of the first groove 11 along its radial path, so that the rotating assembly 2 can reciprocate along the radial path of the first groove 11 under the action of the elastic member 6. This allows the elastic member 6 to deform when the unlocking force applied by the handle paddle 5 to the paddle assembly 3 is greater than a preset value, and the first locking part 21 and the second locking part 31 disengage, thereby cutting off the transmission between the rotating assembly 2 and the paddle assembly 3.

[0084] In one embodiment, such as Figure 7 , Figure 8 and Figure 10As shown, the rotating component 2 is provided with an arc-shaped waisted groove 23, and a notch 231 is provided on any arc-shaped side of the arc-shaped waisted groove 23. A guide surface 232 is provided on the notch 231, and the notch 231 is the first snap-fit ​​part 21. Specifically, the guide surface 232 is a guide slope or a guide arc surface, and of course, it is preferred to be a guide slope. More specifically, the radial angle between the guide slope and the notch 231 is 20° to 60°, specifically any one of 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° and 60°. Of course, it can also be other angles according to actual needs.

[0085] like Figure 7 , Figure 8 and Figure 9 As shown, the paddle assembly 3 is provided with a locking block 34, which is the second locking part 31; the locking block 34 is located in the arc-shaped waist groove 23 and is adapted to lock into the notch 231; that is, the locking block 34 is provided with a profile that is adapted to fit the guide surface 232.

[0086] When the unlocking force applied by the handle paddle 5 to the drive gear 32 is greater than a preset value, the rotating component 2 can move radially relative to the paddle component 3 under the guidance of the guide surface 232.

[0087] In specific usage, such as Figures 7 to 10 As shown, when the unlocking force applied by the handle paddle 5 to the paddle assembly 3 is greater than the preset value, due to the presence of the guide surface 232, the first locking part 21 and the second locking part 31 can be easily disengaged, causing the elastic element 6 to deform and realize the transmission cut-off between the rotating assembly 2 and the paddle assembly 3; at the same time, under the guidance of the arc-shaped waist groove 23, the rotating assembly 2 can move stably and reset.

[0088] In this embodiment, such as Figures 7 to 10 As shown, an arc-shaped waisted groove 23 is provided on the rotating component 2, and a notch 231 is provided on any arc-shaped edge of the arc-shaped waisted groove 23. A guide surface 232 is provided on the notch 231, which can facilitate the disengagement of the first locking part 21 and the second locking part. At the same time, the arc-shaped waisted groove 23 can ensure the stability of the movement after the rotating component 2 and the paddle component 3 are cut off, and avoid poor reciprocating movement stability and difficulty in resetting due to the rotating component 2 and the lock housing 1 falling off.

[0089] In one embodiment, such as Figures 7 to 10 As shown, the notch 231 is located on the arc-shaped edge away from the first axis X; the elastic element 6 causes the rotating assembly 2 to tend to move closer to the first axis X.

[0090] Specifically, the elastic element 6 is a torsion spring, which is sleeved on the slider 22 of the rotating assembly 2. One end of the torsion spring is in sliding contact with a part inside the lock housing 1, and the other end of the torsion spring is in contact with the rotating assembly 2. Preferably, the rotating assembly 2 includes a rotating component and a slider 22. The rotating component is provided with a through hole, and the slider 22 passes through the through hole and is rotatably connected to the rotating component. At this time, the torsion spring is sleeved on the slider 22, one end of the torsion spring is in contact with the slider 22, and the other end of the torsion spring is in contact with the rotating component.

[0091] In this embodiment, the notch 231 is located on the arc-shaped side away from the first axis X; the elastic member 6 makes the rotating assembly 2 tend to move closer to the first axis X, which facilitates the arrangement of the elastic member 6.

[0092] In an embodiment not shown, the notch 231 is located on the arcuate edge near the first axis X; the elastic element 6 causes the rotating assembly 2 to tend to move away from the first axis X. In this structure, the space for arranging the elastic element 6 is limited, making its arrangement inconvenient and hindering maintenance of the lock body.

[0093] In one embodiment, such as Figures 1 to 6 As shown, the lock body also includes a drive shaft 7, which is rotatably disposed inside the lock housing 1 around the first axis X. The drive shaft 7 is provided with a drive hole 71 and a drive part 72. The drive hole 71 is adapted to be sleeved with the output shaft of the motor. Specifically, the drive part 72 is a lever, which can make drive contact with the two ends of the rotating assembly 2 along the rotation direction of the rotating assembly 2 to drive the rotating assembly 2 to reciprocate so as to realize the locking or unlocking action.

[0094] In this embodiment, the drive unit 72 can make drive contact with both ends of the rotating component 2 along the rotation direction of the rotating component 2 to drive the rotating component 2 to reciprocate, which can increase the number of rotations of the motor's unlocking or locking action and avoid directly driving the stationary rotating component 2 when the motor is stationary.

[0095] In one embodiment, such as Figures 1 to 3 As shown, the latch assembly 4 includes a main latch component 41, which is slidably disposed within the lock housing 1. The main latch component 41 has a drive groove 411, specifically, the drive groove 411 is a rectangular groove open on one side; as shown... Figure 11 and Figure 12 As shown, the two edges of the opening of the drive groove 411 are beveled to form an anti-shrinkage part 4111 and an anti-extension part 4112, respectively; the paddle assembly 3 is provided with a paddle head 35, which is located in the drive groove 411 to drive the main locking tongue component 41 to reciprocate.

[0096] When the main bolt component 41 is retracted into the lock housing 1, the dial 35 rotates out from the drive groove 411 and abuts against the anti-extension part 4112 to prevent the main bolt component 41 from sliding out of the lock housing 1; when the main bolt component 41 is extended out of the lock housing 1, the dial 35 rotates out from the drive groove 411 and abuts against the anti-retraction part 4111 to prevent the main bolt component 41 from retracting into the lock housing 1.

[0097] In this embodiment, such as Figure 11 and Figure 12 As shown, by beveling the two edges of the drive groove 411 opening of the main bolt, an anti-extension part 4112 and an anti-retraction part 4111 are formed respectively, which limit the main bolt part 41 when it is fully retracted into the lock housing 1 and when it is fully extended out of the lock housing 1, thereby maintaining the stability of the main bolt position.

[0098] In some embodiments, such as Figures 1 to 3 As shown, the latch assembly 4 also includes a slanted latch component 42, a top and bottom hook component 43, an upper latch component 44, and a lower latch component 45, etc. The slanted latch component 42, the top and bottom hook component 43, the upper latch component 44, and the lower latch component 45 are all directly or indirectly connected to the paddle assembly 3 for transmission.

[0099] In one embodiment, such as Figure 11 and Figure 12 As shown, the lock body also includes a force-bearing push plate 8, which is located inside the lock housing 1. The first end of the force-bearing push plate 8 is rotatably connected to the lock housing 1 via a rotating shaft.

[0100] The main bolt component 41 is provided with a connecting guide groove 412 and a limiting groove 413. The second end of the force-bearing push plate 8 is slidably disposed in the guide groove 412 and can enter the limiting groove 413 after the main bolt component 41 extends out of the lock body to prevent the main bolt component 41 from moving into the lock shell 1.

[0101] It should be noted that when the main bolt component 41 extends out of the lock housing 1 and the second end of the force-receiving push plate 8 moves from the guide groove 412 to the limiting groove 413, one way to drive the force-receiving push plate 8 is to use a rotary transmission assembly to drive the force-receiving push plate 8 to rotate around its first end and enter the limiting groove 413 to prevent the main bolt component 41 from retracting and to limit its movement. The rotary transmission assembly can be connected to the paddle assembly 3 for transmission, and the force-receiving push plate 8 will not be driven when the second end of the force-receiving push plate 8 has not reached the limiting groove 413.

[0102] In this embodiment, by providing a connecting guide groove 412 and a limiting groove 413 on the main bolt component 41, and providing a force-bearing push plate 8 inside the lock housing 1, the first end of the force-bearing push plate 8 is rotatably connected to the lock housing 1, and the second end of the force-bearing push plate 8 slides in the guide groove 412. When the main bolt component 41 is fully extended outside the lock housing 1, the second end of the force-bearing push plate 8 can enter the limiting groove 413 to limit the main bolt component 41. Thus, the main bolt component 41 can be locked in position under the simultaneous limiting of the force-bearing push plate 8 and the dial 35, which can prevent the dial 35 from deforming and causing the lock body to fail.

[0103] In a specific embodiment, Figure 5 and Figure 6 As shown, the lock body also includes a limiting gear 9, which is rotatably disposed inside the lock housing 1 and is connected to the paddle assembly 3 in a transmission manner. The limiting gear 9 is provided with a limiting part 91, and the lower part of the limiting groove 413 is connected to the guide groove 412. The limiting part 91 can push the second end of the force-bearing push plate 8 into and restrict it in the limiting groove 413 during the extension of the main lock tongue component 41.

[0104] Specifically, the paddle assembly 3 is connected to the handle assembly via a limiting gear 9.

[0105] In this embodiment, by setting a limiting gear 9 that is connected to the paddle assembly 3 for transmission, and setting a limiting part 91 on the limiting gear 9 and the limiting wheel, the second end of the force-bearing push plate 8 is pushed into and limited in the limiting groove 413. The driving method is simple and the structure is compact.

[0106] According to an embodiment of this application, in another aspect, a smart lock is provided, comprising: a lock body as described in any one of the embodiments of the first aspect.

[0107] In this embodiment, since the smart lock includes a lock body and has the same effect as the lock body, it will not be described in detail here.

[0108] According to an embodiment of this application, in a third aspect, a door is provided, comprising: a lock body as described in any one of the embodiments of the first aspect, or a smart lock as described in the second aspect.

[0109] Specifically, a door can be the entrance door of a home or company, or the entrance door of a warehouse, etc.

[0110] In this embodiment, since the door includes a lock body or a smart lock, it has the same effect as a lock body or a smart lock, and will not be described in detail here.

[0111] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
