[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0058] In the related technology, the lock body is the main part of the smart lock, including the lock tongue, lock tongue driving mechanism, lock core mounting hole and other structures; the main function of the lock body is to accept the drive of the key or motor, and drive the movement of the lock tongue through the internal transmission mechanism, thereby realizing the locking and unlocking of the door.

[0059] However, after the lock tongue is extended to lock the door, when the motor is stuck or has no power and cannot rotate, since the motor usually uses a worm gear for transmission, its transmission method is irreversible, the handle on the inside of the door will also be stuck and the door cannot be opened.

[0060] In order to solve the above technical problems, the present application provides a lock body, a smart lock and a door, which can enable the smart lock to be unlocked by a handle when the motor cannot run.

[0061] Combine the following Figures 1 to 12 , describing an embodiment of the present application.

[0062] According to an embodiment of the present application, on the one hand, 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 member 6, and the specific scheme is as follows.

[0063] The lock housing 1 is specifically a metal housing, and usually has two slots butted together and connected by rivets or bolts.

[0064] like Figure 5 As shown, the rotating assembly 2 is arranged in the lock housing 1 to reciprocate around the first axis X. Specifically, the first axis X is as shown in FIG. 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 member or a connection, and the first end of the rotating component 2 is provided with a first clamping portion 21.

[0065] like Figure 5 As shown, the paddle assembly 3 is arranged in the lock housing 1 to reciprocate around the first axis X. Specifically, the reciprocating rotation trajectory of the paddle assembly 3 is an arc line. The paddle assembly 3 is provided with a second clamping portion 31 and a driving gear portion 32 .

[0066] The lock tongue assembly 4 is slidably disposed in the lock housing 1 and is transmission-connected to the paddle assembly 3 ; specifically, the lock tongue assembly 4 includes a main lock tongue component 41 , an oblique lock tongue component, and the like.

[0067] It should be noted that the above “the lock tongue assembly 4 is slidably disposed in the lock housing 1 and is drivingly connected to the paddle assembly 3” means that the lock tongue component can be directly drivingly connected to the paddle assembly 3, or can be transmission-connected via other driving intermediate components.

[0068] As shown in 5 , the handle paddle 5 is rotatably disposed in the lock housing 1 , and is suitable for being transmission-connected with the handle through a spline or an axial hole with an irregular cross-section. The handle paddle 5 is transmission-connected with the driving gear portion 32 .

[0069] like Figure 5As shown, the elastic member 6 is specifically a spring or a rubber body with a certain elastic expansion and contraction amount; under the action of the elastic member 6 , the first clamping portion 21 of the rotating assembly 2 is clamped with the second clamping portion 31 .

[0070] When the unlocking force applied by the handle paddle 5 to the driving gear portion 32 is greater than a preset value, the first clamping portion 21 is disengaged from the second clamping portion 31 , so that at least the first end of the rotating assembly 2 moves 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 member 6 to the rotating assembly 2 can keep the first clamping portion 21 and the second clamping portion 31 in a clamped state, that is, the rotating assembly 2 and the paddle assembly 3 rotate synchronously.

[0072] In the specific use process, such as Figures 5 to 6 As shown, after the lock tongue assembly 4 of the lock body extends out of the lock body to lock, if the motor of the lock body is stuck due to a power failure or other reasons, the person inside the door can apply a greater unlocking force to the handle so that the unlocking force applied by the handle paddle 5 to the paddle assembly 3 is greater than a preset value, such as Figure 6 and Figure 8 As shown, the elastic member 6 is deformed, the first clamping portion 21 is disengaged from the second clamping portion 31, at least the first end of the rotating assembly 2 is radially moved, and the first clamping portion 21 is disconnected from the second clamping portion 31 to prevent the motor from locking the paddle assembly 3, so that the person inside the door can directly unlock the door through the handle.

[0073] In this embodiment, if Figures 1 to 10 As shown, by arranging a reciprocating rotation arrangement of a rotating assembly 2 and a paddle assembly 3 in the lock shell 1, under the action of the elastic member 6, the first clamping portion 21 located at the first end of the rotating assembly 2 is clamped with the second clamping portion 31 located on the paddle assembly 3; thereby, when the lock body is locked and the motor in the lock body is stuck, a person inside the door applies a greater unlocking force to the handle, so that the unlocking force applied by the handle paddle 5 to the paddle assembly 3 is greater than a preset value, the elastic member 6 is deformed, the first clamping portion 21 is disengaged from the second clamping portion 31, at least the first end of the rotating assembly 2 is radially moved, and the first clamping portion 21 is disconnected from the second clamping portion 31, so as to prevent the motor from locking the paddle assembly 3. At the same time, since the lock tongue assembly 4 is in transmission connection with the paddle assembly 3, the person inside the door can directly perform an unlocking action through the handle, so that the lock tongue assembly 4 is retracted into the lock shell 1, thereby realizing the unlocking inside the door.

[0074] In one embodiment, Figure 4As shown, a first slide groove 11 and a second slide groove 12 are provided in the lock housing 1. 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 side surfaces of the lock housing 1; the first slide groove 11 and the second slide groove 12 are both 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 specific 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 Fig.10 As shown, a slider 22 is provided at the second end of the rotating component 2, and the slider 22 is slidably connected to the first slide groove 11, and 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 respectively 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 Fig. 9 As shown, an arc block 33 is provided on the paddle assembly 3 to prevent the paddle assembly 3 from rotating on its own. The arc block 33 is adapted to be slidably connected with the second slide groove 12. Specifically, the radius of the arc block 33 is the same as the radius of the second slide groove 12, and the two ends of the arc block 33 are respectively slidably connected with the two second slide grooves 12 on the lock housing 1.

[0077] In the specific use process, after the lock tongue assembly 4 of the lock body extends out of the lock body to lock, if the motor of the lock body is stuck due to power failure or other reasons, the person inside the door can apply a greater unlocking force to the handle to make the unlocking force applied by the handle paddle 5 to the paddle assembly 3 greater than the preset value, and the elastic member 6 is deformed, such as Figure 6 and Figure 8 As shown, the first clamping portion 21 is disengaged from the second clamping portion 31, the rotating assembly 2 rotates around the axis of its slider 22, and the paddle assembly 3 can rotate relative to the rotating assembly 2 in the second slide groove 12 to achieve transmission cutoff between the rotating assembly 2 and the paddle assembly 3; this is convenient for people inside the door to unlock the door through the handle; when the unlocking is completed, the handle is reset, thereby resetting the second clamping portion 31 and re-engaging with the first clamping portion 21 under the action of the elastic member 6.

[0078] In some embodiments not shown, a first slide groove 11 and a second slide groove 12 are provided in the lock housing 1. 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 side surfaces of the lock housing 1; the first slide groove 11 and the second slide groove 12 are both arc-shaped grooves, and the central axis of the first slide groove 11 and the central axis of the second slide groove 12 both 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] A slider 22 is provided at the second end of the rotating component 2. The slider 22 is arc-shaped, but the radial thickness of the slider 22 along the rotating trajectory of the rotating component 2 is smaller than the radial width of the first slide groove 11, so that the rotating component 2 can reciprocate along the radial direction of the first slide groove 11 under the action of the elastic member 6.

[0080] Specifically, the elastic member 6 is fixed on the rotating component 2, and an arc-shaped limit plate is arranged in the lock body, the central axis of the arc-shaped limit plate coincides with the first axis X, and a roller or a ball is arranged at the end of the elastic member 6 that contacts the arc-shaped limit plate to reduce the sliding friction between the elastic member 6 and the arc-shaped limit plate; more specifically, the number of elastic members 6 can be multiple, evenly distributed between the rotating component 2 and the arc-shaped limit 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 limit plate is arranged 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 limit plate is located on the side of the rotating component 2 away from the first axis X.

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

[0083] In this embodiment, the radial thickness of the slider 22 along the rotation trajectory of the rotating component 2 is smaller than the radial width of the first slide groove 11, so that the rotating component 2 can reciprocate radially along the first slide groove 11 under the action of the elastic member 6, so that when the unlocking force applied by the handle paddle 5 to the paddle assembly 3 is greater than the preset value, the elastic member 6 is deformed, the first clamping portion 21 is disengaged from the second clamping portion 31, and the transmission between the rotating component 2 and the paddle assembly 3 is cut off.

[0084] In one embodiment, Figure 7 , Figure 8 and Fig.10As shown, an arcuate waist groove 23 is provided on the rotating component 2, and a notch 231 is provided on any arcuate edge of the arcuate waist groove 23, and a guide surface 232 is provided on the notch 231, and the notch 231 is the first clamping portion 21; specifically, the guide surface 232 is a guiding inclined surface, or a guiding arcuate surface, and of course, it is preferably a guiding inclined surface; more specifically, the radial angle between the guiding inclined surface and the position of the notch 231 is 20°~60°, specifically any one of 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° and 60, and of course, it can also be other angles according to actual needs.

[0085] like Figure 7 , Figure 8 and Fig. 9 As shown, a clamping block 34 is provided on the paddle assembly 3, and the clamping block 34 is the second clamping portion 31; the clamping block 34 is located in the arc-shaped waisted round groove 23, and is adapted to be clamped with the notch 231; that is, a profile adapted to fit the guide surface 232 is provided on the clamping block 34.

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

[0087] In the specific use process, 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 a preset value, the existence of the guide surface 232 can facilitate the first clamping portion 21 and the second clamping portion 31 to fall off, causing the elastic member 6 to deform, thereby realizing the transmission cut-off between the rotating assembly 2 and the paddle assembly 3; at the same time, the rotating assembly 2 can be stably moved and reset under the guidance of the arc-shaped waist groove 23.

[0088] In this embodiment, if Figures 7 to 10 As shown, an arcuate waist groove 23 is provided on the rotating component 2, and a notch 231 is provided on any arcuate side of the arcuate waist groove 23, and a guide surface 232 is provided on the notch 231, which can facilitate the detachment of the first clamping part 21 and the second clamping part; at the same time, the setting of the arcuate waist groove 23 can ensure the stability of movement after the transmission between the rotating component 2 and the paddle component 3 is cut off, and avoid the poor reciprocating movement stability and reset difficulty caused by the detachment of the rotating component 2 and the lock shell 1.

[0089] In one embodiment, Figures 7 to 10 As shown, the notch 231 is located on the arc edge away from the first axis X; the elastic member 6 makes the rotating assembly 2 have a tendency to approach the first axis X.

[0090] Specifically, the elastic member 6 is a torsion spring, which is sleeved on the slider 22 of the rotating component 2, one end of the torsion spring is in sliding and limiting contact with a part in the lock housing 1, and the other end of the torsion spring is in limiting contact with the rotating component 2; preferably, the rotating component 2 includes a rotating component and a slider 22, the rotating component is provided with a through hole, the slider 22 passes through the through hole and is rotatably connected with the rotating component; at this time, the torsion spring is sleeved on the slider 22, one end of the torsion spring is in limiting contact with the slider 22, and the other end of the torsion spring is in limiting contact with the rotating component.

[0091] In this embodiment, the notch 231 is located on the arc edge away from the first axis X; the elastic member 6 makes the rotating assembly 2 have a tendency to approach the first axis X, which can facilitate the arrangement of the elastic member 6.

[0092] In an embodiment not shown, the notch 231 is located on the arc edge close to the first axis X; the elastic member 6 makes the rotating assembly 2 tend to move away from the first axis X. In this structure, the elastic member 6 has a tight space for arrangement, is inconvenient to arrange, and is inconvenient to maintain with the lock body.

[0093] In one embodiment, Figures 1 to 6 As shown, the lock body also includes a driving shaft 7, which is rotatable around the first axis X and is arranged in the lock shell 1. A driving hole 71 and a driving part 72 are provided on the driving shaft 7, and the driving hole 71 is suitable for being sleeved with the output shaft of the motor; specifically, the driving part 72 is a shift block, and the driving part 72 can make driving contact with the two end parts of the rotating component 2 along the rotation direction of the rotating component 2 to drive the rotating component 2 to reciprocate and realize the locking action or the unlocking action.

[0094] In this embodiment, the driving part 72 can make driving contact with the two end parts of the rotating component 2 along the rotation direction of the rotating component 2 to drive the rotating component 2 to rotate back and forth, 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, Figures 1 to 3 As shown, the bolt assembly 4 includes a main bolt component 41, which is slidably disposed in the lock housing 1. A driving groove 411 is disposed on the main bolt component 41. Specifically, the driving groove 411 is a rectangular groove with one side open; Fig.11 and Fig.12 As shown, the two edges of the opening of the driving groove 411 are beveled to form an anti-shrinkage portion 4111 and an anti-extension portion 4112 respectively; a paddle head 35 is provided on the paddle assembly 3, and the paddle head 35 is located in the driving groove 411 to drive the main lock tongue component 41 to slide back and forth.

[0096] Among them, when the main lock tongue component 41 is retracted into the lock shell 1, the dial head 35 is rotated out of the driving groove 411 and abuts against the anti-extension portion 4112 to prevent the main lock tongue component 41 from sliding out of the lock shell 1; when the main lock tongue component 41 is extended out of the lock shell 1, the dial head 35 is rotated out of the driving groove 411 and abuts against the anti-retraction portion 4111 to prevent the main lock tongue component 41 from retracting into the lock shell 1.

[0097] In this embodiment, if Fig.11 and Fig.12 As shown, by beveling the two edges of the opening of the driving groove 411 of the main lock tongue, an anti-extension portion 4112 and an anti-retraction portion 4111 are formed respectively, so as to limit the main lock tongue component 41 when the main lock tongue component 41 is fully retracted into the lock housing 1 and when the main lock tongue component 41 is fully extended from the lock housing 1, thereby maintaining the stability of the main lock tongue position.

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

[0099] In one embodiment, Fig.11 and Fig.12 As shown, the lock body further includes a force-bearing push plate 8, which is located in the lock housing 1, and a first end of the force-bearing push plate 8 is rotationally connected to the lock housing 1 via a rotating shaft.

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

[0101] It should be noted that, when the main lock tongue component 41 extends out of the lock shell 1 and the second end of the force-bearing push plate 8 moves to the limit groove 413 in the guide groove 412, a driving method of the force-bearing push plate 8 can be to use a rotary transmission component to drive the force-bearing push plate 8 to rotate around its first end and enter the limit groove 413 to prevent the main lock tongue component 41 from retracting. The rotary transmission component can be connected to the paddle component 3 in transmission, and when the second end of the force-bearing push plate 8 has not reached the limit groove 413, the force-bearing push plate 8 is not driven.

[0102] In this embodiment, a connecting guide groove 412 and a limiting groove 413 are provided on the main lock tongue component 41, and a force-bearing push plate 8 is provided in the lock shell 1. The first end of the force-bearing push plate 8 is rotatably connected to the lock shell 1, and the second end of the force-bearing push plate 8 slides in the guide groove 412. When the main lock tongue component 41 is fully extended out of the lock shell 1, the second end of the force-bearing push plate 8 can enter the limiting groove 413 to limit the main lock tongue component 41, so that the main lock tongue component 41 can be locked in position under the simultaneous limitation of the force-bearing push plate 8 and the dial head 35, which can avoid deformation of the dial head 35 and cause failure of the lock body.

[0103] In a specific embodiment, Figure 5 and Figure 6 As shown, the lock body also includes a limiting gear 9, which is rotatably arranged in the lock shell 1 and is transmission-connected to the paddle assembly 3. A limiting portion 91 is arranged on the limiting gear 9, and the lower portion of the limiting groove 413 is connected to the guide groove 412. The limiting portion 91 can push the second end of the force-bearing push plate 8 into and limit it in the limiting groove 413 during the extension process of the main lock tongue component 41.

[0104] Specifically, the paddle assembly 3 is transmission-connected to the handle assembly via the limit gear 9 .

[0105] In this embodiment, a limiting gear 9 is provided which is transmission-connected to the paddle assembly 3, and a limiting portion 91 is provided on the limiting gear 9 and on the limiting wheel, so that 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 the present application, on the other hand, a smart lock is provided, comprising: a lock body in any one embodiment of the first aspect.

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

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

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

[0110] In this embodiment, because the door includes a lock body or a smart lock, it has the same effect as the lock body or the smart lock and is not repeated here.

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