Description

Technical Field

[0001] This invention relates to the field of smart door lock technology, and more specifically, to an emergency unlocking structure and a smart door lock having the same. Background Technology

[0002] Currently, with the rapid development of the smart home industry, smart door locks, as an important part of home security, are undergoing a transformation from simple functions to diversified and user-friendly services. In order to improve the user experience, the unlocking method on the inside of some smart door locks has been changed to one-button unlocking. That is, users can unlock the door by touching the display screen on the inside of the door, without having to hold and turn the handle as in traditional unlocking methods. In addition to the above unlocking method, the inside of smart door locks usually also has a separate emergency unlocking structure for emergency unlocking in case of power failure or damage. The emergency unlocking structure usually includes a knob and a corresponding linkage. The linkage is inserted into the unlocking end of the door lock structure. Users can turn the knob to drive the linkage to rotate and achieve emergency unlocking.

[0003] In the existing technology, the linkage between the knob and the door lock structure is usually also connected to the unlocking motor of the conventional unlocking method. That is, in the conventional unlocking method, the linkage is driven to rotate by the motor to unlock the lock structure. However, the above-mentioned emergency unlocking methods for smart door locks have the following two main problems: Question 1: There is a drive connection between the linkage and the motor. When the user turns the knob to rotate the linkage for emergency unlocking, the linkage will cause the motor shaft to reverse, which can easily damage the motor, especially when the motor is in the locked state. Question 2: In actual operation, due to the special structure of the lock, the knob needs to be rotated multiple times to unlock. Summary of the Invention

[0004] The main objective of this invention is to provide an emergency unlocking structure and a smart lock having the same, so as to solve the problem that the emergency unlocking method of existing smart locks is inconvenient and can damage the unlocking motor.

[0005] To achieve the above objectives, according to one aspect of the present invention, an emergency unlocking structure is provided, comprising: a panel assembly having a mounting cavity and a mounting portion and a through portion communicating with the mounting cavity; an operating assembly movably mounted at the mounting portion, at least a portion of the operating assembly extending into the mounting cavity; an unlocking member movably disposed at the through portion, one end of the unlocking member extending into the mounting cavity, and the other end of the unlocking member inserted into a lock hole of a lock cylinder structure, wherein at least a portion of the outer peripheral surface of the unlocking member is anti-rotationally engaged with the inner wall of the lock hole; and a transmission assembly disposed within the mounting cavity, the transmission assembly comprising at least two meshing gears, and gears being provided on both the operating assembly and the unlocking member, so that when the operating assembly is rotated, the unlocking member is driven to rotate via the transmission assembly.

[0006] Furthermore, the mounting part is a recess, and a through hole is provided on the bottom wall of the recess. The emergency unlocking structure also includes: a knob structure, at least part of which is located inside the mounting part; and a connecting rod, which is disposed on the knob structure. One end of the connecting rod extends into the mounting cavity through the through hole to connect with the gear drive.

[0007] Furthermore, the knob structure is rotatably configured, and multiple gears include a drive wheel that is driven and connected to the connecting rod. The drive wheel is provided with a connecting structure, the connecting structure having a first mating part, and the connecting rod having a second mating part. One of the first and second mating parts is a mating protrusion, and the other of the first and second mating parts is a mating recess. The mating protrusion extends into the mating recess and engages with the mating recess to prevent rotation, so that when the knob structure drives the connecting rod to rotate, the drive wheel is driven to rotate through the connecting rod.

[0008] Furthermore, the emergency unlocking structure also includes a reset component, which is disposed within the mounting section. The reset component is driven to connect with the operating component, and the reset component drives the operating component to rotate, thereby resetting the operating component.

[0009] Furthermore, a cylindrical mounting part is provided at the through hole, the inner hole of the cylindrical mounting part is connected to the through hole, and the reset element is a torsion spring and is sleeved on the cylindrical mounting part. The two ends of the torsion spring are respectively connected to the knob structure and the bottom wall of the mounting part.

[0010] Furthermore, the knob structure is rotatably and vertically mounted within the mounting section. The emergency unlocking structure also includes an elastic element, which is mounted within the mounting section and connected to the knob structure. The knob structure has a concealed position and a working position. When the knob structure is in the concealed position, it is located within the mounting section. When the knob structure is in the working position, at least a portion of it extends outside the mounting section. The elastic element applies an elastic force to the knob structure, causing it to move toward the bottom wall away from the mounting section, to switch the knob structure to the working position.

[0011] Furthermore, a limiting protrusion is provided on the outer peripheral surface of the knob structure, and a limiting recess is provided on the inner wall of the mounting part. The limiting recess has a first annular recess, a second annular recess, and a clearance recess. The first annular recess and the second annular recess are spaced apart along the height direction of the mounting part. The first annular recess is located closer to the bottom wall of the mounting part than the second annular recess. The clearance recess connects the first annular recess and the second annular recess. When the limiting protrusion is located in the first annular recess, the knob structure is limited to a hidden position by the limiting stop between the limiting protrusion and the first annular recess. When the knob structure rotates and drives the limiting protrusion to move to the clearance recess, the knob structure, under the action of the elastic element, drives the limiting protrusion to move along the clearance recess to the second annular recess, so as to switch the knob structure to the working position.

[0012] Furthermore, the multiple gears include a drive wheel that is driven and connected to the connecting rod. The drive wheel is provided with a connecting structure, which has a clearance fit protrusion. The connecting rod has a clearance fit recess. The clearance fit protrusion is plate-shaped and inserted into the clearance fit recess. Along the direction from the central axis of the connecting rod to the outer peripheral surface of the connecting rod, the width of the clearance fit recess gradually increases, so that the clearance fit recess has two fan-shaped recesses. After the clearance fit protrusion rotates by a preset clearance angle, at least a portion of the outer peripheral surface of the clearance fit protrusion is stopped by the inner wall of the clearance fit recess, thereby driving the drive wheel to rotate.

[0013] Furthermore, when the knob structure is in the hidden position, the portion of the allowance fitting protrusion extending into the allowance fitting recess has a length L1, and the knob structure has a movement distance L2 between the hidden position and the working position, with the length L1 being greater than the movement distance L2.

[0014] According to another aspect of the present invention, a smart lock is provided, comprising a lock cylinder structure and an emergency unlocking structure. The emergency unlocking structure is the one described above.

[0015] According to the technical solution of the present invention, the panel assembly of the emergency unlocking structure has a mounting cavity and a mounting part and a through part communicating with the mounting cavity. The operating component is movably mounted at the mounting part, and at least a portion of the operating component extends into the mounting cavity. The unlocking member is movably inserted through the through part, with one end of the unlocking member extending into the mounting cavity and the other end of the unlocking member inserted into the lock hole of the lock cylinder structure. At least a portion of the outer peripheral surface of the unlocking member is anti-rotationally fitted with the inner wall of the lock hole. The transmission component is disposed in the mounting cavity and includes at least two meshing gears. Gears are provided on both the operating component and the unlocking member so that when the operating component is rotated, the unlocking member is driven to rotate through the transmission component. Thus, the emergency unlocking structure in this application, while eliminating the interlock with the unlocking device of the smart lock, achieves a drive connection between the operating component and the unlocking component through the setting of gears. This allows the operator to adjust the transmission ratio between the gears according to the actual structure of the lock cylinder, thereby ensuring that the user only needs to rotate a small angle to unlock the lock cylinder. It is evident that this application not only avoids the motor damage problem caused by the motor interlock between the emergency unlocking structure and the unlocking device, but also reduces the operating difficulty for the operator. This solves the problem of inconvenient emergency unlocking methods in existing smart locks that can damage the unlocking motor, thus improving the user experience. Attached Figure Description

[0021] To address the inconvenience and potential damage to the unlocking motor caused by the emergency unlocking method in existing smart door locks, this application provides an emergency unlocking structure and a smart door lock incorporating it.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, the emergency unlocking structure includes a panel assembly 10, an operating assembly 20, an unlocking member 30, and a transmission assembly 40. The panel assembly 10 has a mounting cavity 11 and a mounting portion 12 and a through portion 13 communicating with the mounting cavity 11. The operating assembly 20 is movably mounted at the mounting portion 12, with at least a portion of the operating assembly 20 extending into the mounting cavity 11. The unlocking member 30 is movably disposed at the through portion 13, with one end of the unlocking member 30 extending into the mounting cavity 11 and the other end inserted into the lock hole of the lock cylinder structure 1. At least a portion of the outer peripheral surface of the unlocking member 30 has a non-rotational fit with the inner wall of the lock hole. The transmission assembly 40 is disposed within the mounting cavity 11 and includes at least two meshing gears 41. Gears 41 are provided on both the operating assembly 20 and the unlocking member 30 so that when the operating assembly 20 is rotated, the unlocking member 30 is driven to rotate via the transmission assembly 40.

[0024] Applying the technical solution of this embodiment, the panel assembly 10 of the emergency unlocking structure has a mounting cavity 11 and a mounting portion 12 and a through portion 13 communicating with the mounting cavity 11. The operating component 20 is movably mounted at the mounting portion 12, and at least a portion of the operating component 20 extends into the mounting cavity 11. The unlocking member 30 is movably passed through the through portion 13, with one end of the unlocking member 30 extending into the mounting cavity 11 and the other end of the unlocking member 30 inserted into the lock hole of the lock cylinder structure 1. At least a portion of the outer peripheral surface of the unlocking member 30 is anti-rotationally engaged with the inner wall of the lock hole. The transmission component 40 is disposed in the mounting cavity 11 and includes at least two meshing gears 41. Gears 41 are provided on both the operating component 20 and the unlocking member 30 so that when the operating component 20 is rotated, the unlocking member 30 is driven to rotate through the transmission component 40. Thus, in this embodiment, the emergency unlocking structure eliminates the interlock with the unlocking device 2 of the smart door lock, while setting gear 41 to achieve the drive connection between the operating component 20 and the unlocking component 30. This allows the operator to adjust the transmission ratio between gears 41 according to the actual structure of the lock cylinder structure 1, thereby ensuring that the user only needs to rotate a small angle to unlock the lock cylinder structure 1. It can be seen that this embodiment not only avoids the motor damage problem caused by the motor interlock between the emergency unlocking structure and the unlocking device 2, but also reduces the operating difficulty for the operator, thereby solving the problem that the emergency unlocking method of the smart door lock in the prior art is inconvenient and will cause damage to the unlocking motor, and improving the user experience.

[0025] In this embodiment, the lock cylinder structure 1 actually has two lock holes, namely the first lock hole 101 and the second lock hole 102. The unlocking device 2 of the smart door lock is also set in the mounting cavity 11. That is, the unlocking component 30 of the emergency unlocking structure in this embodiment is inserted into the first lock hole 101 to realize the unlocking operation, while the unlocking structure of the unlocking device 2 is inserted into the second lock hole 102 to realize the unlocking operation.

[0026] It should be noted that the specific structure of lock cylinder structure 1 is relatively conventional and will not be described in detail here.

[0027] Specifically, the unlocking component 30 is actually a square shaft with a square cross-section, and the structure of the first lock hole 101 is adapted to the structure of the unlocking component 30 so that the first lock hole 101 can be rotated by the unlocking component 30, thereby realizing the unlocking operation.

[0028] In this embodiment, the transmission assembly 40 includes three gears 41. One gear 41 is disposed on the operating assembly 20, and another gear 41 is disposed on the unlocking member 30. There is also a gear 41 disposed between the two gears 41. The three gears mesh with each other to realize the transmission of action.

[0029] It should be noted that the number of gears 41 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, four, five, six, or more gears 41.

[0030] like Figure 1 and Figure 2 As shown, the mounting portion 12 is a recess, and a through hole 121 is provided on the bottom wall of the recess. The emergency unlocking structure also includes: a knob structure 21, at least part of which is located within the mounting portion 12; and a connecting rod 22, which is disposed on the knob structure 21. One end of the connecting rod 22 extends into the mounting cavity 11 through the through hole 121 to drive the gear 41. In this way, while the knob structure 21 facilitates the user's turning operation, the connecting rod 22 enables the drive connection between the knob structure 21 and the gear 41. At the same time, the recess also helps to hide the knob structure 21, preventing it from protruding too much and thus improving the aesthetic appearance of the smart lock.

[0031] like Figure 1 and Figure 2As shown, the knob structure 21 is rotatably configured. Multiple gears 41 include a drive wheel 42 driven by the connecting rod 22. The drive wheel 42 has a connecting structure 43, which has a first mating portion 431. The connecting rod 22 has a second mating portion 221. One of the first and second mating portions 431 is a mating protrusion, and the other is a mating recess. The mating protrusion extends into the mating recess and engages with it to prevent rotation. When the knob structure 21 drives the connecting rod 22 to rotate, the connecting rod 22 drives the drive wheel 42 to rotate. This configuration ensures that the connecting rod 22 can drive the connecting structure 43 to rotate, thereby driving the drive wheel 42 to rotate, while also allowing for a certain vertical movement allowance between the connecting structure 43 and the connecting rod 22. This reduces the impact of machining errors on their assembly and lowers the assembly difficulty for workers. At the same time, the above-mentioned configuration also makes the structure of the first mating part 431 and the second mating part 221 more flexible and diverse, so as to adapt to different working conditions and usage requirements, and also improve the processing flexibility of the workers.

[0032] In this embodiment, the first mating part 431 is a mating protrusion, and the second mating part 221 is a mating recess. The mating protrusion is actually a columnar structure with a cross-section in the shape of a cross, while the connecting rod 22 is actually a tubular structure with its inner hole forming the mating recess. The cross-sectional structure of the mating recess matches the structure of the mating protrusion, thereby achieving an anti-rotation fit between the two. Furthermore, after the mating protrusion extends into the mating recess, it can slide along the extending direction of the mating recess, thus providing a certain allowance for assembly between the two.

[0033] In other embodiments shown in the accompanying drawings, the first mating part is a mating recess, and the second mating part is a mating protrusion.

[0034] like Figure 1 and Figure 2 As shown, the emergency unlocking structure also includes a reset component 50, which is disposed within the mounting portion 12. The reset component 50 is driven to the operating component 20, and the reset component 50 drives the operating component 20 to rotate, thereby resetting the operating component 20. Thus, after the user rotates the knob structure 21 to perform the unlocking operation, the reset component 50 can drive the knob structure 21 to reverse, achieving automatic reset of the knob structure 21 and further enhancing the user experience.

[0035] like Figure 1 and Figure 2As shown, a cylindrical mounting portion 122 is provided at the through hole 121. The inner hole of the cylindrical mounting portion 122 communicates with the through hole 121. The reset member 50 is a torsion spring and is sleeved on the cylindrical mounting portion 122. The two ends of the torsion spring are connected to the knob structure 21 and the bottom wall of the mounting portion 12, respectively. In this way, the cylindrical mounting portion 122 provides a mounting base for the torsion spring while also guiding and supporting it to prevent the torsion spring from deflecting, thereby improving the reset reliability of the reset member 50. At the same time, the above configuration also makes the structure of the reset member 50 simpler and easier to process and implement, thereby reducing the processing difficulty for workers and the processing cost of the reset member 50.

[0036] In this embodiment, the panel assembly 10 includes a front panel 14, a middle frame 15, and a rear panel 16 arranged sequentially. The three together form a mounting cavity 11. The mounting part 12 is disposed on the front panel 14 and the middle frame 15. That is, the front panel 14 is provided with a corresponding hole-shaped part, and the middle frame 15 is provided with a corresponding annular protrusion. The two together form the mounting part 12. The through part 13 is disposed on the rear panel 16.

[0037] It should be noted that the structure of the panel assembly 10 is not limited to this and can be adjusted according to the actual working conditions and usage requirements, as long as the corresponding mounting cavity 11, mounting part 12 and through part 13 are provided.

[0038] Example 2

[0039] The difference between the emergency unlocking structure in Embodiment 2 and Embodiment 1 is that the driving method of the knob structure 21 is different.

[0040] like Figures 3 to 8 As shown, the knob structure 21 is rotatably and vertically mounted within the mounting portion 12. The emergency unlocking structure also includes an elastic element 60, which is disposed within the mounting portion 12 and connected to the knob structure 21. The knob structure 21 has a hidden position and a working position. When the knob structure 21 is in the hidden position, it is located within the mounting portion 12; when it is in the working position, at least a portion of it extends outside the mounting portion 12. The elastic element 60 applies an elastic force to the knob structure 21, moving it toward the bottom wall away from the mounting portion 12, to switch it to the working position. Thus, while the user operates the knob structure 21 to rotate the connecting rod 22 and unlock the door, they can also hide the knob structure 21 by pressing it. This not only makes the surface of the smart lock smoother and more aesthetically pleasing but also prevents children from accidentally turning the knob structure 21 and opening the door.

[0041] Optionally, a cover structure (such as a sealing cap, elastic plug, etc.) can be provided on the panel assembly 10. After the user presses the knob structure 21 to the hidden position, the cover structure sealing installation part 12 can be operated to completely hide the knob structure 21, thereby eliminating the possibility of children accidentally operating the knob structure 21 to open the door.

[0042] like Figure 3 , Figure 4 and Figure 6 As shown, a limiting protrusion 211 is provided on the outer peripheral surface of the knob structure 21, and a limiting recess 123 is provided on the inner wall of the mounting part 12. The limiting recess 123 has a first annular recess 1231, a second annular recess 1232 and a clearance recess 1233. The first annular recess 1231 and the second annular recess 1232 are spaced apart along the height direction of the mounting part 12. The first annular recess 1231 is located closer to the bottom wall of the mounting part 12 than the second annular recess 1232. The clearance recess 1233 connects the first annular recess 1231 and the second annular recess 1232. Specifically, when the limiting protrusion 211 is located within the first annular recess 1231, the limiting stop between the limiting protrusion 211 and the first annular recess 1231 limits the knob structure 21 to the hidden position. When the knob structure 21 rotates and drives the limiting protrusion 211 to the avoidance recess 1233, the knob structure 21, under the action of the elastic member 60, drives the limiting protrusion 211 along the avoidance recess 1233 to the second annular recess 1232, thereby switching the knob structure 21 to the working position. In this way, the above-mentioned arrangement of the limiting recess 123 realizes the fixing of the knob structure 21 in the hidden position and the turning action in the working position.

[0043] like Figure 4 As shown, when the user rotates the knob structure 21 until the limit protrusion 211 aligns with the avoidance recess 1233, the user can press the knob structure 21 down to the hidden position, or the knob structure 21 can move to the working position under the action of the elastic member 60.

[0044] like Figure 6 As shown, after the user presses the knob structure 21 down to the hidden position, the knob structure can be rotated by a preset angle so that the knob structure 21 drives the limiting protrusion 211 to move into the first annular recess 1231. At this time, the upper surface of the limiting protrusion 211 and the inner wall of the first annular recess 1231 limit and stop, and the knob structure 21 is limited to the hidden position.

[0045] like Figure 7As shown, when the knob structure 21 moves to the second annular recess 1232 under the action of the elastic member 60, the operator can operate the knob structure 21 to rotate and unlock. At the same time, the second annular recess 1232 can also stop the knob structure 211 to prevent it from popping out of the mounting part 12.

[0046] like Figure 5 and Figure 8 As shown, the multiple gears 41 include a drive wheel 42 driven by a connecting rod 22. The drive wheel 42 is provided with a connecting structure 43, which has a clearance fit protrusion 432. The connecting rod 22 has a clearance fit recess 222. The clearance fit protrusion 432 is plate-shaped and inserted into the clearance fit recess 222. Along the direction from the central axis of the connecting rod 22 to its outer circumferential surface, the width of the clearance fit recess 222 gradually increases, so that the clearance fit recess 222 has two fan-shaped recesses 2221. When the clearance fit protrusion 432 rotates by a preset clearance angle, at least a portion of the outer circumferential surface of the clearance fit protrusion 432 is stopped by the inner wall of the clearance fit recess 222, thereby driving the drive wheel 42 to rotate. In this way, the above-mentioned settings can prevent the user from driving the unlocking component 30 through the transmission component 40 when the operation knob structure 21 is turned into or out of the avoidance recess 1233, thereby causing the lock cylinder structure 1 to be mistakenly locked.

[0047] In this embodiment, the allowance fitting recess 222 has a symmetrical structure.

[0048] like Figure 5 As shown, when the limiting protrusion 211 moves to align with the clearance recess 1233, the clearance fitting protrusion 432 is exactly in the middle position of the clearance fitting recess 222. That is, the plate surface of the clearance fitting protrusion 432 only makes line contact with the inner wall of the clearance fitting recess 222 at the narrowest position of the clearance fitting recess 222, while there is a certain preset gap between it and the inner wall of the fan-shaped recess 2221 of the clearance fitting recess 222. During the process of the user operating the knob structure 21 to rotate, thereby driving the connecting rod 22 to rotate, only when rotated to the position shown... Figure 8 Only after the position shown can the connecting rod 22 drive the connecting structure 43 to rotate, which in turn drives the drive wheel 42 to rotate, so as to realize the subsequent unlocking operation.

[0049] In this embodiment, the preset margin angle is 15°.

[0050] In this embodiment, when the knob structure 21 is in the hidden position, the portion of the allowance engagement protrusion 432 extending into the allowance engagement recess 222 has a length L1, and the knob structure 21 has a movement distance L2 between the hidden position and the working position, with the length L1 being greater than the movement distance L2. This arrangement ensures that when the knob structure 21 switches between the hidden position and the working position, the allowance engagement protrusion 432 and the allowance engagement recess 222 can always engage with each other, preventing the allowance engagement protrusion 432 from dislodging from the allowance engagement recess 222, thereby improving the operational stability of the emergency unlocking structure.

[0051] This embodiment also provides a smart door lock (not shown), which includes a lock cylinder structure 1 and an emergency unlocking structure. The emergency unlocking structure is the one described above.

[0052] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: The panel assembly of the emergency unlocking structure has a mounting cavity and a mounting part and a through part communicating with the mounting cavity. The operating component is movably mounted at the mounting part, with at least a portion of the operating component extending into the mounting cavity. The unlocking component is movably inserted through the through part, with one end of the unlocking component extending into the mounting cavity and the other end inserted into the lock hole of the lock cylinder structure. At least a portion of the outer peripheral surface of the unlocking component is anti-rotationally fitted with the inner wall of the lock hole. The transmission component is disposed in the mounting cavity and includes at least two meshing gears. Gears are provided on both the operating component and the unlocking component so that when the operating component is rotated, the unlocking component is driven to rotate through the transmission component. Thus, the emergency unlocking structure in this application, while eliminating the interlock with the unlocking device of the smart lock, achieves a drive connection between the operating component and the unlocking component through the setting of gears. This allows the operator to adjust the transmission ratio between the gears according to the actual structure of the lock cylinder, thereby ensuring that the user only needs to rotate a small angle to unlock the lock cylinder. It is evident that this application not only avoids the motor damage problem caused by the motor interlock between the emergency unlocking structure and the unlocking device, but also reduces the operating difficulty for the operator. This solves the problem of inconvenient emergency unlocking methods in existing smart locks that can damage the unlocking motor, thus improving the user experience.
