Description

Technical Field

[0001] The present invention relates to the technical field of smart door locks, and in particular to an emergency unlocking structure and a smart door lock having the same. Background Art

[0002] At present, with the rapid development of the smart home field, smart door locks, as an important part of home security, are undergoing a transformation from simple functions to diversified and humanized 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, the user can open the door by touching the display screen on the inside of the door, without having to hold and turn the handle as in the traditional unlocking method. In addition to the above unlocking method, a separate emergency unlocking structure is usually provided on the inside of the smart door lock to perform emergency unlocking when the smart door lock is powered off or damaged. The emergency unlocking structure usually includes a knob and a corresponding connecting rod. The connecting rod is inserted into the unlocking end of the door lock structure. The user can drive the connecting rod to rotate by turning the knob to achieve emergency unlocking operation.

[0003] In the prior art, the connecting rod between the knob and the door lock structure is usually also connected to the unlocking motor of the conventional unlocking, that is, in the conventional unlocking mode, the motor drives the connecting rod to rotate to realize the unlocking of the lock structure;

[0004] However, the above emergency unlocking method of the smart door lock has the following two main problems:

[0005] Problem 1: There is a driving connection between the connecting rod and the motor. When the user turns the knob to drive the connecting rod to rotate for emergency unlocking, the connecting rod will drive the motor shaft to reverse, which can easily damage the motor, especially when the motor is in the locked state.

[0006] Question 2: During actual operation, the knob may need to be rotated multiple times before it can be unlocked due to the special structure of the lock. Summary of the invention

[0007] The main purpose of the present invention is to provide an emergency unlocking structure and a smart door lock having the same, so as to solve the problem that the emergency unlocking method of the smart door lock in the prior art is inconvenient and may cause damage to the unlocking motor.

[0039] In order to solve the problem that the emergency unlocking method of the smart door lock in the prior art is inconvenient and may cause damage to the unlocking motor, the present application provides an emergency unlocking structure and a smart door lock having the same.

[0040] Embodiment 1

[0041] 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 an installation cavity 11 and a mounting portion 12 and a penetration portion 13 connected to the installation cavity 11. The operating assembly 20 can be movably installed at the installation portion 12, and at least part of the operating assembly 20 extends into the installation cavity 11. The unlocking member 30 can be movably penetrated at the penetration portion 13, one end of the unlocking member 30 extends into the installation cavity 11, and the other end of the unlocking member 30 is inserted into the lock hole of the lock core structure 1, and at least part of the outer peripheral surface of the unlocking member 30 is locked with the inner wall of the lock hole. The transmission assembly 40 is arranged in the installation cavity 11, and the transmission assembly 40 includes two mutually meshing gears 41. The gears 41 are arranged on 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 through the transmission assembly 40.

[0042] Applying the technical solution of this embodiment, the panel assembly 10 of the emergency unlocking structure has an installation cavity 11 and a mounting portion 12 and a penetration portion 13 connected to the installation cavity 11, the operating assembly 20 can be movably installed at the installation portion 12, at least part of the operating assembly 20 extends into the installation cavity 11, the unlocking member 30 can be movably penetrated at the penetration portion 13, one end of the unlocking member 30 extends into the installation cavity 11, and the other end of the unlocking member 30 is inserted into the lock hole of the lock core structure 1, at least part of the outer circumferential surface of the unlocking member 30 is locked with the inner wall of the lock hole, the transmission assembly 40 is arranged in the installation cavity 11, the transmission assembly 40 includes two gears 41 meshing with each other, and the gears 41 are arranged on 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 through the transmission assembly 40. In this way, the emergency unlocking structure in this embodiment not only cancels the interlocking with the unlocking device 2 of the smart door lock, but also realizes the driving connection between the operating component 20 and the unlocking member 30 by setting the gear 41, so that the staff can adjust the transmission ratio between the gears 41 according to the actual structure of the lock core structure 1, thereby ensuring that the user only needs to turn a small angle to achieve the unlocking operation of the lock core structure 1. It can be seen that this embodiment can not only avoid the motor damage problem caused by the motor interlocking between the emergency unlocking structure and the unlocking device 2, but also reduce the operation difficulty of the staff, 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, thereby improving the user experience.

[0043] In this embodiment, the lock core structure 1 actually has two lock holes, namely a first lock hole 101 and a second lock hole 102, and the unlocking device 2 of the smart door lock is also arranged in the installation cavity 11, that is, the unlocking member 30 of the emergency unlocking structure in this embodiment is inserted in the first lock hole 101 to realize the unlocking operation, and the unlocking structure of the unlocking device 2 is inserted in the second lock hole 102 to realize the unlocking operation.

[0044] It should be noted that the specific structure of the lock core structure 1 is relatively conventional and will not be described in detail here.

[0045] Specifically, the unlocking member 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 member 30 so that the first lock hole 101 can be driven to rotate by the unlocking member 30 to achieve the unlocking operation.

[0046] In this embodiment, the transmission assembly 40 includes three gears 41, one gear 41 is arranged on the operating assembly 20, another gear 41 is arranged on the unlocking member 30, and another gear 41 is arranged between the two gears 41. The three gears are meshed with each other to realize motion transmission.

[0047] It should be noted that the number of gears 41 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of gears 41 is two, four, five, six, or more.

[0048] like Figure 1 and Figure 2 As shown, the mounting portion 12 is a recessed portion, and a through hole 121 is provided on the bottom wall of the recessed portion. The emergency unlocking structure further includes: a knob structure 21, at least part of which is located in the mounting portion 12; a connecting rod 22, which is provided on the knob structure 21, and one end of the connecting rod 22 extends into the mounting cavity 11 through the through hole 121 to be drivingly connected with the gear 41. In this way, while the knob structure 21 facilitates the user to perform the screwing operation, the connecting rod 22 can realize the driving connection between the knob structure 21 and the gear 41. At the same time, the setting of the recessed portion also helps to hide the knob structure 21, so as to avoid the knob structure 21 from protruding too large, thereby improving the appearance of the smart door lock.

[0049] like Figure 1 and Figure 2 As shown, the knob structure 21 is rotatably arranged, and the plurality of gears 41 include a driving wheel 42 drivingly connected to the connecting rod 22, and a connecting structure 43 is arranged on the driving wheel 42, and the connecting structure 43 has a first matching portion 431, and the connecting rod 22 has a second matching portion 221, and one of the first matching portion 431 and the second matching portion 221 is a matching protrusion, and the other of the first matching portion 431 and the second matching portion 221 is a matching recess, and the matching protrusion extends into the matching recess and is locked with the matching recess, so that when the knob structure 21 drives the connecting rod 22 to rotate, the driving wheel 42 is driven to rotate through the connecting rod 22. In this way, the above arrangement ensures that the connecting rod 22 can drive the connecting structure 43 to rotate, and then drive the driving wheel 42 to rotate, while ensuring that there is a certain vertical activity margin between the connecting structure 43 and the connecting rod 22, thereby reducing the influence of the processing error on the assembly between the two, and reducing the assembly difficulty of the staff. At the same time, the above arrangement also makes the structures of the first matching portion 431 and the second matching portion 221 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0050] In this embodiment, the first matching portion 431 is a matching protrusion, and the second matching portion 221 is a matching recess. The matching protrusion is actually a columnar structure with a "cross" cross section, and the connecting rod 22 is actually a tubular structure, whose inner hole forms a matching recess, and the cross-sectional structure of the matching recess matches the structure of the matching protrusion, thereby achieving a non-rotating fit between the two. At the same time, after the matching protrusion penetrates into the matching recess, it can also slide along the extension direction of the matching recess, thereby providing a certain margin for the assembly between the two.

[0051] In other embodiments shown in the accompanying drawings, the first matching portion is a matching recess, and the second matching portion is a matching protrusion.

[0052] like Figure 1 and Figure 2 As shown, the emergency unlocking structure further includes a reset member 50, which is disposed in the mounting portion 12 and is drivingly connected to the operating assembly 20. The reset member 50 drives the operating assembly 20 to rotate so as to reset the operating assembly 20. In this way, after the user operates the knob structure 21 to rotate and thereby realizes the unlocking operation, the reset member 50 can drive the knob structure 21 to reverse so as to realize the automatic reset of the knob structure 21, further improving the user experience.

[0053] like Figure 1 and Figure 2 As shown, a cylindrical mounting portion 122 is provided at the through hole 121, and the inner hole of the cylindrical mounting portion 122 is connected to 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 respectively connected to the knob structure 21 and the bottom wall of the mounting portion 12. In this way, the cylindrical mounting portion 122 can guide and support the torsion spring while providing a mounting base for the torsion spring to prevent the torsion spring from being skewed, thereby improving the reset reliability of the reset member 50. At the same time, the above-mentioned arrangement also makes the structure of the reset member 50 simpler, easier to process and realize, thereby reducing the processing difficulty of the staff and the processing cost of the reset member 50.

[0054] In this embodiment, the panel assembly 10 includes a front panel 14, a middle frame 15 and a rear panel 16 which are arranged in sequence, and the three together surround a mounting cavity 11. The mounting portion 12 is arranged on the front panel 14 and the middle frame 15, that is, the front panel 14 is provided with a corresponding hole-shaped portion, and the middle frame 15 is provided with a corresponding annular protrusion, and the two together surround to form the mounting portion 12, and the penetration portion 13 is arranged on the rear panel 16.

[0055] It should be noted that the structure of the panel assembly 10 is not limited thereto, and can be adjusted according to actual working conditions and usage requirements, and it is only necessary to ensure that the corresponding installation cavity 11, the installation portion 12 and the penetration portion 13 are provided.

[0056] Embodiment 2

[0057] The difference between the emergency unlocking structure in the second embodiment and that in the first embodiment is that the driving mode of the knob structure 21 is different.

[0058] like Figures 3 to 8As shown, the knob structure 21 is rotatably and liftably arranged in the mounting portion 12, and the emergency unlocking structure also includes: an elastic member 60, which is arranged in the mounting portion 12 and connected to the knob structure 21, and the knob structure 21 has a hidden position and a working position. When the knob structure 21 is in the hidden position, the knob structure 21 is located in the mounting portion 12; when the knob structure 21 is in the working position, at least part of the knob structure 21 extends out of the mounting portion 12. Among them, the elastic member 60 is used to apply an elastic force to the knob structure 21 to move toward the side of the bottom wall away from the mounting portion 12, so as to switch the knob structure 21 to the working position. In this way, when the user operates the knob structure 21 to rotate to drive the connecting rod 22 to rotate, thereby realizing the unlocking operation, the knob structure 21 can also be hidden by pressing the knob structure 21, which not only makes the surface of the smart door lock smoother and more beautiful, but also can prevent children from accidentally operating the knob structure 21 to rotate and cause the door to open.

[0059] Optionally, a cover structure (such as a sealing cover, an 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 can be operated to seal the mounting portion 12 to achieve complete hiding of the knob structure 21, thereby eliminating the possibility of children accidentally operating the knob structure 21 to open the door.

[0060] 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 portion 12. The limiting recess 123 has a first annular recess 1231, a second annular recess 1232 and an avoidance recess 1233. The first annular recess 1231 and the second annular recess 1232 are spaced apart along the height direction of the mounting portion 12. The first annular recess 1231 is provided close to the bottom wall of the mounting portion 12 relative to the second annular recess 1232, and the avoidance recess 1233 connects the first annular recess 1231 and the second annular recess 1232. When the limiting protrusion 211 is located in the first annular recess 1231, the knob structure 21 is limited in the hidden position by the limiting stop between the limiting protrusion 211 and the first annular recess 1231; when the knob structure 21 rotates and drives the limiting protrusion 211 to move to the avoidance recess 1233, the knob structure 21 drives the limiting protrusion 211 along the avoidance recess 1233 to move into the second annular recess 1232 under the action of the elastic member 60, so as to switch the knob structure 21 to the working position. In this way, the above-mentioned setting of the limiting recess 123 realizes the fixing of the knob structure 21 in the hidden position and the twisting action in the working position.

[0061] like Figure 4As shown, when the user rotates the knob structure 21 until the limiting protrusion 211 is aligned with the avoidance recess 1233 , the user can press the knob structure 21 down to the hidden position, or the knob structure 21 moves to the working position under the action of the elastic member 60 .

[0062] like Figure 6 As shown, after the user presses the knob structure 21 down to the hidden position, the knob structure can be operated to rotate 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 are limited and stopped, and the knob structure 21 is limited in the hidden position.

[0063] like Figure 7 As shown, when the knob structure 21 moves to the second annular recess 1232 under the action of the elastic member 60, the staff can operate the knob structure 21 to rotate to achieve the unlocking operation. At the same time, the second annular recess 1232 can also be limited and stopped by the limiting protrusion 211 to prevent the knob structure 21 from popping out of the mounting portion 12.

[0064] like Figure 5 and Figure 8 As shown, the plurality of gears 41 include a driving wheel 42 drivingly connected to the connecting rod 22, a connecting structure 43 is provided on the driving wheel 42, the connecting structure 43 has a margin matching protrusion 432, the connecting rod 22 has a margin matching recess 222, the margin matching protrusion 432 is plate-shaped and inserted into the margin matching recess 222, and the width of the margin matching recess 222 gradually increases in the direction from the central axis of the connecting rod 22 to the outer peripheral surface of the connecting rod 22, so that the margin matching recess 222 has two fan-shaped recesses 2221. Among them, after the margin matching protrusion 432 rotates by a preset margin angle, at least part of the outer peripheral surface of the margin matching protrusion 432 and the inner wall of the margin matching recess 222 are limited and stopped to drive the driving wheel 42 to rotate. In this way, the above arrangement can prevent the unlocking member 30 from being driven to move by the transmission assembly 40 when the user operates the knob structure 21 to rotate into or out of the avoidance recess 1233, thereby preventing the lock core structure 1 from being mistakenly locked.

[0065] In this embodiment, the residual matching recess 222 is a symmetrical structure.

[0066] like Figure 5As shown in FIG. 2 , when the limiting protrusion 211 moves to align with the avoidance recess 1233, the margin matching protrusion 432 is exactly in the middle position of the margin matching recess 222, that is, the plate surface of the margin matching protrusion 432 is in line contact with the inner wall of the margin matching recess 222 only at the narrowest position of the margin matching recess 222, and there is a certain preset gap between the inner side wall of the fan-shaped recess 2221 of the margin matching recess 222. When the user operates the knob structure 21 to rotate to drive the connecting rod 22 to rotate, the knob structure 21 can be rotated to the middle position of the connecting rod 22. Figure 8 After the connecting rod 22 reaches the position shown in the figure, it can drive the connecting structure 43 to rotate, and then drive the driving wheel 42 to rotate, so as to realize the subsequent unlocking operation.

[0067] In this embodiment, the preset margin angle is 15°.

[0068] In this embodiment, when the knob structure 21 is in the hidden position, the portion of the margin matching protrusion 432 extending into the margin matching recess 222 has a length L1, and the knob structure 21 has a movement distance L2 between the hidden position and the working position, and the length L1 is greater than the movement distance L2. In this way, the above arrangement ensures that when the knob structure 21 switches between the hidden position and the working position, the margin matching protrusion 432 and the margin matching recess 222 can always match each other to prevent the margin matching protrusion 432 from falling out of the margin matching recess 222, thereby improving the operational stability of the emergency unlocking structure.

[0069] This embodiment also provides a smart door lock (not shown), which includes a lock core structure 1 and an emergency unlocking structure. The emergency unlocking structure is the above-mentioned emergency unlocking structure.

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] The panel assembly of the emergency unlocking structure has an installation cavity and an installation portion and a penetration portion connected to the installation cavity. The operating assembly can be movably installed at the installation portion, and at least part of the operating assembly extends into the installation cavity. The unlocking piece can be movably penetrated at the penetration portion, one end of the unlocking piece extends into the installation cavity, and the other end of the unlocking piece is inserted into the lock hole of the lock core structure. At least part of the outer circumferential surface of the unlocking piece is locked with the inner wall of the lock hole. The transmission assembly is arranged in the installation cavity, and the transmission assembly includes two gears meshing with each other. Gears are arranged on the operating assembly and the unlocking piece, so that when the operating assembly is rotated, the unlocking piece is driven to rotate through the transmission assembly. In this way, the emergency unlocking structure in the present application not only cancels the interlocking with the unlocking device of the smart door lock, but also realizes the driving connection between the operating component and the unlocking component by setting gears, so that the staff can adjust the transmission ratio between the gears according to the actual structure of the lock core structure, thereby ensuring that the user only needs to turn a small angle to achieve the unlocking operation of the lock core structure. It can be seen that the present application can not only avoid the motor damage problem caused by the motor interlocking between the emergency unlocking structure and the unlocking device, but also reduce the operation difficulty of the staff, 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, thereby improving the user experience.
