[0036] In order to facilitate the understanding of the embodiments of the present invention, the embodiments of the present invention will be described more comprehensively with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the embodiments of the present invention herein are only for the purpose of describing specific implementations and are not intended to limit the present invention.

[0038] The inventor of the present invention has found that the smart locks on the market usually have two unlocking methods: mechanical unlocking and electric unlocking, that is, not only can the unlocking be achieved by rotating the handle or knob, but also by intelligent methods including but not limited to fingerprint recognition, password input, electronic card, face recognition or app software (application, mobile phone application software) control. In order to have these two unlocking functions, the internal structure of the smart lock usually includes many parts such as knob shaft, motor and transmission parts. The assembly method of multiple parts of the smart locks on the market will increase the space occupied by the parts, resulting in the size of the smart locks on the market being generally larger, which is not conducive to the transportation and assembly of the smart locks, and the smart locks on the market cannot be adapted to traditional mechanical locks.

[0039] In order to improve at least some of the above problems, the present invention provides a smart lock, which can drive the motor transmission assembly to rotate through a driving mechanism, and the motor transmission assembly then drives the lock tongue toggle to rotate through a knob shaft, thereby driving the lock tongue assembly to extend or retract relative to the lock shell to achieve electric locking or unlocking of the smart lock; it can also drive the lock tongue toggle to rotate by manually rotating the knob shaft to achieve mechanical locking or unlocking of the smart lock; because the knob shaft is inserted through the lock tongue toggle and the motor transmission assembly, the lock tongue toggle and the motor transmission assembly are arranged along the axial direction of the knob shaft, which reduces the space occupied by the lock tongue toggle and the motor transmission assembly, realizes the miniaturization of the smart lock, and improves the convenience of transportation and assembly of the smart lock. The smart lock provided by the present invention is described in detail below in conjunction with the specific implementation methods and the drawings in the specification.

[0040] See also Figures 1 to 5The present invention provides a smart lock 1, comprising a first base 10, a lock body 30, a transmission mechanism 40 and a driving mechanism 50. The lock body 30 comprises a lock shell 31 and a bolt assembly 33. The lock shell 31 is connected to the first base 10. The bolt assembly 33 is movably arranged on the lock shell 31 and can be extended or retracted relative to the lock shell 31. The transmission mechanism 40 comprises a bolt toggle 42, a motor transmission assembly 44 and a knob shaft 46. The bolt toggle 42 is rotatably arranged on the lock shell 31 and is transmission-connected with the bolt assembly 33. The motor transmission assembly 44 is rotatably arranged on the first base 10. The knob shaft 46 penetrates the bolt toggle 42 and the motor transmission assembly 44. The driving mechanism 50 is transmission-connected with the motor transmission assembly 44 to drive the motor transmission assembly 44 to rotate. The motor transmission assembly 44 drives the bolt toggle 42 to rotate through the knob shaft 46.

[0041] Based on this, the motor transmission assembly 44 can be driven to rotate by the driving mechanism 50, and the motor transmission assembly 44 can then drive the lock tongue toggle member 42 to rotate through the knob shaft 46, thereby driving the lock tongue assembly 33 to extend or retract relative to the lock shell 31, thereby realizing the electric locking or unlocking of the smart lock 1; the lock tongue toggle member 42 can also be driven to rotate by manually rotating the knob shaft 46, thereby realizing the mechanical locking or unlocking of the smart lock 1, wherein the smart lock 1 can be applied to left-door or right-door opening scenarios to meet different door opening requirements; since the knob shaft 46 passes through the lock tongue toggle member 42 and the motor transmission assembly 44, the lock tongue toggle member 42 and the motor transmission assembly 44 are arranged along the axial direction of the knob shaft 46, thereby reducing the space occupied by the lock tongue toggle member 42 and the motor transmission assembly 44, realizing the miniaturization of the smart lock 1, and improving the convenience of transportation and assembly of the smart lock 1.

[0042] Specifically, the first base 10 can be used to install the driving mechanism 50 and part of the transmission mechanism 40. In this embodiment, the first base 10 is roughly a hollow cylindrical structure. In other embodiments, the first base 10 can also be a hollow rectangular parallelepiped or other shapes, which can be set according to actual conditions.

[0043] See also Figures 6 to 11 The smart lock 1 further includes a first cover plate 20, which is covered on the first base 10 to enclose the drive mechanism 50 and part of the transmission mechanism 40. The first cover plate 20 can be fixed to the first base 10 by screws, or by bonding, clamping, etc. The shape of the first cover plate 20 is adapted to the shape of the first base 10. Therefore, in this embodiment, the first cover plate 20 is roughly a circular plate-shaped structure. In other embodiments, when the first base 10 is a rectangular parallelepiped, the first cover plate 20 can also be a rectangular plate-shaped structure.

[0044] The lock body 30 includes a lock shell 31 and a lock tongue assembly 33. The lock shell 31 is connected to the first base 10. The lock shell 31 can be used to install the lock tongue assembly 33 and the lock tongue toggle 42. The lock shell 31 is roughly arranged in the middle position of the first base 10, which can improve the appearance consistency of the smart lock 1. The lock tongue assembly 33 is movably arranged in the lock shell 31, and can be extended or retracted relative to the lock shell 31. When the lock tongue assembly 33 is extended relative to the lock shell 31, the smart lock 1 can be locked; when the lock tongue assembly 33 is retracted relative to the lock shell 31, the smart lock 1 can be unlocked. The lock tongue assembly 33 has a maximum extension position and a maximum retraction position, wherein the maximum extension position refers to the limit position of the lock tongue assembly 33 when the lock tongue assembly 33 extends the maximum length relative to the lock shell 31, and the maximum retraction position refers to the limit position of the lock tongue assembly 33 when the lock tongue assembly 33 is retracted to the minimum length relative to the lock shell 31.

[0045] The lock housing 31 includes a bottom plate 312 and a panel 314. The panel 314 is covered on the bottom plate 312. The panel 314 and the bottom plate 312 can be connected to form an integral structure by plugging. In this embodiment, the panel 314 is a substantially rectangular plate-like structure and is arranged opposite to the first cover plate 20. The bottom plate 312 is a substantially "L"-shaped plate-like structure. The bottom plate 312 is located on a side of the lock housing 31 away from the first cover plate 20. In other embodiments, the bottom plate 312 can be opposite to the first cover plate 20, and the panel 314 can be located on a side of the lock housing 31 away from the first cover plate 20. The panel 314 has a length direction D1 and a width direction D2 perpendicular to the length direction D1.

[0046] The lock housing 31 also includes a lining plate 316, an outer sleeve 318 and an inner sleeve 319. The outer sleeve 318 is a roughly cylindrical structure and is sleeved on the inner sleeve 319. The outer sleeve 318 and the inner sleeve 319 are arranged on one side of the panel 314 along the length direction D1 of the panel 314; the lining plate 316 is connected to the outer sleeve 318 and the inner sleeve 319 on the side away from the panel 314, and the lining plate 316 is used to connect with the door frame to realize the installation of the smart lock 1 on the door frame; the lock tongue assembly 33 is passed through the inner sleeve 319 and the lining plate 316, and can be extended or retracted relative to the lining plate 316.

[0047] The lock tongue assembly 33 includes a lock tongue body 332 and a lock tongue connector 334 . The lock tongue connector 334 can move along the length direction D1 of the panel 314 driven by the lock tongue toggle member 42 . The lock tongue body 332 is connected to one end of the lock tongue connector 334 and can extend or retract relative to the lining plate 316 .

[0048] In this embodiment, the lock tongue body 332 is a roughly cylindrical structure. The lock tongue body 332 includes a mounting hole 3321 and a pin hole 3323, wherein the mounting hole 3321 is a blind hole, arranged along the axial direction of the lock tongue body 332, and the mounting hole 3321 is used for the installation of the lock tongue connector 334; the pin hole 3323 is a through hole, which is arranged along the radial direction of the lock tongue body 332 and is connected to the mounting hole 3321. In this embodiment, the pin hole 3323 is arranged at one end of the lock tongue body 332 close to the lock tongue connector 334. The pin hole 3323 can be used for the pin to pass through, so that the pin can pass through the pin hole 3323 and be fixedly connected to the lock tongue connector 334, thereby realizing the fixed connection between the lock tongue connector 334 and the lock tongue body 332.

[0049] The bolt connector 334 includes a connecting section 3341 and a transmission section 3343 connected to each other, wherein the connecting section 3341 is substantially cylindrical, and the transmission section 3343 is substantially an "L"-shaped plate-like structure. The connecting section 3341 is provided with a first groove 3341a and a second groove 3341b sequentially arranged along the length direction D1 of the panel 314, wherein the second groove 3341b is away from the bolt connector 334 relative to the first groove 3341a, and one of the first groove 3341a and the second groove 3341b can correspond to the pin hole 3323, so that the pin can pass through the pin hole 3323 and selectively abut against the bottom of one of the first groove 3341a and the second groove 3341b, so as to fix the bolt connector 334 to the bolt body 332. Since the first groove 3341a and the second groove 3341b are sequentially arranged along the length direction D1 of the panel 314, the extension length of the lock tongue body 332 relative to the lining plate 316 is adjustable. Specifically, when the gap (door gap) between the door panel and the door frame on which the smart lock 1 is installed is too large, the pin hole 3323 can be made to correspond to the second groove 3341b to increase the extension length of the lock tongue body 332 relative to the lining plate 316, so that the lock tongue body 332 can be matched with the lock tongue groove on the door frame; when the door gap is too small, the pin hole 3323 can be made to correspond to the first groove 3341a to reduce the extension length of the lock tongue body 332 relative to the lining plate 316, so that the lock tongue body 332 can be matched with the lock tongue groove on the door frame. In other words, by providing the first groove 3341a and the second groove 3341b, the smart lock 1 can adapt to different door gap sizes, thereby expanding the scope of application of the smart lock 1.

[0050] The connecting section 3341 is also provided with a connecting groove 3341c, which is connected with both the first groove 3341a and the second groove 3341b, that is, the first groove 3341a can be connected with the second groove 3341b via the connecting groove 3341c, so that the pin can be moved from the position corresponding to the first groove 3341a to the position corresponding to the second groove 3341b via the connecting groove 3341c, and there is no need to first disengage the pin from the first groove 3341a and then cooperate with the second groove 3341b. The protruding length of the lock tongue body 332 relative to the lining plate 316 can be adjusted by rotating the lock tongue body 332 at a certain angle and then moving the lock tongue body 332 along the axial direction of the lock tongue connecting piece 334, thereby improving the efficiency of adjusting the protruding length of the lock tongue body 332.

[0051] The transmission section 3343 is provided with a notch 3343a, and the notch 3343a can cooperate with the bolt toggle member 42, so that the rotation of the bolt toggle member 42 can drive the transmission section 3343 to move, thereby driving the bolt body 332 to extend or retract relative to the lining plate 316. The notch 3343a runs through both ends of the transmission section 3343 along the width direction D2, and along the width direction D2 of the bolt connector 334, one end of the notch 3343a has a large opening, and the other end has a small opening, so that the notch 3343a is roughly trumpet-shaped to accommodate the rotation of the bolt toggle member 42.

[0052] A protrusion 3343b is also provided on the side of the transmission section 3343 facing away from the panel 314, and the bottom plate 312 is provided with a guide groove 3121 extending along the length direction D1 of the panel 314. The protrusion 3343b is passed through the guide groove 3121 to limit the moving direction of the lock tongue connector 334, so that the lock tongue connector 334 can only move along the length direction D1 of the panel 314.

[0053] The bolt actuator 42 is rotatably disposed on the lock housing 31 and is transmission-connected to the bolt assembly 33 . Specifically, the bolt actuator 42 can extend into the notch 3343 a , so that the rotation of the bolt actuator 42 can drive the bolt connector 334 to move.

[0054] Please combine Fig.12 The bolt moving member 42 includes a main body 421 and a bolt lever 423. The main body 421 is rotatably disposed on the bottom plate 312. The bolt lever 423 extends outward from the main body 421. The bolt lever 423 is disposed through the bolt assembly 33. In this embodiment, the bolt lever 423 is integrally disposed with the main body 421. In other embodiments, the bolt lever 423 can also be fixedly connected with the main body 421 by welding or other methods.

[0055] The main body 421 includes a first side surface 4212, a second side surface 4214, and a third side surface 4216 which are sequentially connected along the circumference of the main body 421, and the bolt lever 423 is convexly disposed on the third side surface 4216, wherein the first side surface 4212 and the second side surface 4214 are both planes, and the third side surface 4216 is an arc surface. In this embodiment, the first side surface 4212 and the second side surface 4214 are perpendicular to each other. In other embodiments, the first side surface 4212 and the second side surface 4214 may also be at an acute angle or an obtuse angle, which may be set according to actual conditions.

[0056] The main body 421 further includes a first shaft hole 4217, which penetrates the main body 421 along the axial direction of the main body 421. The first shaft hole 4217 can be used for the knob shaft 46 to pass through and is adapted to the knob shaft 46. In this embodiment, the first shaft hole 4217 is a rectangular hole. In other embodiments, the first shaft hole 4217 can also be a square hole, a hexagonal hole, or an elliptical hole, as long as it can be adapted to the knob shaft 46.

[0057] The lock tongue lever 423 is a roughly long bar-shaped structure. In the present embodiment, the lock tongue lever 423 is a roughly square bar-shaped structure. In other embodiments, the lock tongue lever 423 may also be a round bar-shaped structure. Abutment slope 4231 is provided on the side of the lock tongue lever 423 away from the main body 421, and the abutment slope 4231 abuts against the edge of the notch 3343a, so that the lock tongue lever 423 can stop the movement of the lock tongue assembly 33, so that after the lock tongue assembly 33 is extended to the maximum position relative to the lining plate 316, the lock tongue assembly 33 can be self-locked, and the lock tongue assembly 33 is prevented from retracting under the action of external force, thereby improving the safety performance of the smart lock 1.

[0058] The lock body 30 further includes an elastic sheet 35, which is disposed in the lock shell 31 and can selectively abut against the first side surface 4212 or the second side surface 4214. One end of the elastic sheet 35 is fixed to the bottom plate 312, and the other end abuts against the bottom plate 312, and the main body 421 of the elastic sheet 35 corresponds to the hollow part of the lock shell 31, so that the elastic sheet 35 can protrude relative to the lock shell 31 under the abutment of the main body 421. In this embodiment, when the lock tongue body 332 extends relative to the lining plate 316, the elastic sheet 35 abuts against the first side surface 4212; when the lock tongue body 332 retracts relative to the lining plate 316, the elastic sheet 35 abuts against the second side surface 4214. The abutment of the elastic member on the lock tongue toggle 42 can enhance the user's hand feel when operating the lock tongue toggle 42 to rotate, thereby enhancing the user experience. In this embodiment, the elastic sheet 35 can be made of metal. In other embodiments, the elastic sheet 35 can also be made of alloy.

[0059] The motor transmission assembly 44 is rotatably disposed on the first base 10. The motor transmission assembly 44 can rotate relative to the first base 10 under the action of the driving mechanism 50 to drive the lock tongue actuator 42 to rotate through the knob shaft 46, and finally drive the lock tongue body 332 to extend or retract relative to the lining plate 316.

[0060] The motor transmission assembly 44 includes a rotating seat 441 and a transmission member 443, wherein the rotating seat 441 is rotatably arranged on the first base 10 and is coaxially arranged with the lock tongue toggle member 42, and the rotating seat 441 can drive the knob shaft 46 to rotate; the transmission member 443 can be connected to the driving mechanism 50 in a transmission manner, so that the driving mechanism 50 can drive the transmission member 443 to rotate, and the transmission member 443 then drives the rotating seat 441 to rotate. The transmission member 443 is roughly a circular gear structure. The transmission member 443 is sleeved on the rotating seat 441, which improves the integration of the motor transmission assembly 44, further reduces the occupied space of the motor transmission assembly 44, realizes the miniaturization of the smart lock 1, and improves the convenience of transportation and assembly of the smart lock 1.

[0061] The rotating seat 441 includes a rotating body 4412 and a boss 4414, both of which are roughly cylindrical structures, wherein the rotating body 4412 can be rotatably set on the first base 10, the boss 4414 is farther away from the first base 10 than the rotating body 4412, and the diameter of the boss 4414 is smaller than the diameter of the rotating body 4412.

[0062] The rotating seat 441 is provided with a second shaft hole 4416, and the second shaft hole 4416 penetrates the rotating body 4412 and the boss 4414 along the axial direction of the rotating seat 441, and the second shaft hole 4416 can be used for the knob shaft 46 to pass through, and is adapted to the knob shaft 46. The first shaft hole 4217 and the second shaft hole 4416 are coaxially arranged, so that the knob shaft 46 can pass through the first shaft hole 4217 and the second shaft hole 4416 at the same time, so that the rotating seat 441 can drive the lock tongue toggle member 42 to rotate through the knob shaft 46. In this embodiment, the second shaft hole 4416 is a rectangular hole. In other embodiments, the second shaft hole 4416 can also be a square hole, a hexagonal hole or an elliptical hole, as long as it can meet the purpose of being adapted to the knob shaft 46.

[0063] The outer circumference of the rotating seat 441 is convexly provided with a boss 4414a, for example, the boss 4414a is convexly provided on the outer circumference of the boss 4414, and the boss 4414a is generally a long strip. The inner circumference of the transmission member 443 is concavely provided with an arc groove 4432, and the boss 4414a is at least partially disposed in the arc groove 4432, and the width of the boss 4414a is smaller than the length of the arc groove 4432, so that the transmission member 443 can drive the rotating seat 441 to rotate after rotating a certain angle. The arc groove 4432 includes a first abutting surface 4432a and a second abutting surface 4432b along the arc extension direction. For example, the boss 4414a abuts against the first abutting surface 4432a. When the driving mechanism 50 drives the transmission member 443 to rotate in the clockwise direction, the transmission member 443 drives the rotating seat 441 to rotate in the clockwise direction. When the driving mechanism 50 drives the transmission member 443 to rotate in the counterclockwise direction, the boss 4414a is away from the first abutting surface 4432a, and the transmission member 443 will not drive the rotating seat 441 to rotate until the boss 4414a abuts against the second abutting surface 4432b. The transmission member 443 will drive the rotating seat 441 to rotate. In this way, when the knob shaft 46 drives the rotating seat 441 to rotate, the rotating seat 441 will not drive the transmission member 443 to rotate, that is, the driving mechanism 50 cannot be driven to move when the mechanical locking or unlocking is performed, thereby reducing the damage to the driving mechanism 50.

[0064] In this embodiment, the number of the bosses 4414 a and the number of the arc-shaped grooves 4432 are both two. The bosses 4414 a are disposed at two radial ends of the convex column 4414 , and the arc-shaped grooves 4432 are disposed at two radial ends of the transmission member 443 .

[0065] The motor transmission assembly 44 also includes a transmission paddle 445, which is sleeved on the rotating seat 441, further improving the integration of the motor transmission assembly 44, thereby further reducing the occupied space of the motor transmission assembly 44. The transmission paddle 445 is provided with a transmission groove 4451 adapted to the boss 4414a, so that the rotation of the rotating seat 441 can drive the transmission paddle 445 to rotate. In this embodiment, the transmission groove 4451 is roughly a U-shaped groove to adapt to the long strip of boss 4414a. In one embodiment, when the boss 4414a is semi-cylindrical, the transmission groove 4451 can also be a semi-circular arc groove. In other embodiments, the transmission groove 4451 can also be other shapes to meet the purpose of being able to adapt to the boss 4414a.

[0066] The knob shaft 46 is provided through the bolt toggle member 42 and the motor transmission assembly 44. For example, the knob shaft 46 is provided through the first shaft hole 4217 of the bolt toggle member 42 and the second shaft hole 4416 of the rotating seat 441 in sequence, so that the rotation of the knob shaft 46 can drive the bolt toggle member 42 and the rotating seat 441 to rotate. In this embodiment, the knob shaft 46 is generally a sheet-like structure, and the cross-section of the knob shaft 46 is generally rectangular. One end of the knob shaft 46 can be fixedly connected to an operating knob disposed inside the door, so that the user can achieve mechanical locking or mechanical unlocking of the smart lock 1 when rotating the operating knob inside the door. Since the rotation of the knob shaft 46 can drive the lock tongue toggle 42 and the rotating seat 441 to rotate, when the knob shaft 46 cooperates with the lock tongue toggle of the traditional mechanical lock, it can drive the lock tongue of the traditional mechanical lock to extend or retract, that is, the overall structure formed by the first base 10, the motor transmission assembly 44 and the drive mechanism 50 provided by the present invention can be adapted to most mechanical locks on the market, expanding the scope of application of the smart lock 1. In other words, when the lock body 30 provided by the present invention is replaced with a traditional mechanical lock, the mechanical lock can be quickly replaced with an electric lock, meeting the market demand for rapid replacement of mechanical locks with electric locks, and ensuring the convenience of later maintenance and maintenance of the electric lock.

[0067] See also Figure 6 , the driving mechanism 50 is connected to the motor transmission assembly 44 to drive the motor transmission assembly 44 to rotate, and the motor transmission assembly 44 then drives the bolt toggle 42 to rotate through the knob shaft 46. In this way, the motor transmission assembly 44 can be driven to rotate by the driving mechanism 50, and the motor transmission assembly 44 then drives the bolt toggle 42 to rotate through the knob shaft 46, thereby driving the bolt assembly 33 to extend or retract relative to the lock shell 31, thereby realizing the electric locking or unlocking of the smart lock 1; the bolt toggle 42 can also be driven to rotate by manually rotating the knob shaft 46, thereby realizing the mechanical locking or unlocking of the smart lock 1; because the knob shaft 46 is penetrated by the bolt toggle 42 and the motor transmission assembly 44, the bolt toggle 42 and the motor transmission assembly 44 are arranged along the axial direction of the knob shaft 46, thereby reducing the occupied space of the bolt toggle 42 and the motor transmission assembly 44, realizing the miniaturization of the smart lock 1, and improving the convenience of transportation and assembly of the smart lock 1.

[0068] The driving mechanism 50 includes a driving motor 51 and a reduction box 53. The driving motor 51 outputs torque. The driving motor is connected to the reduction box 53 in a transmission manner. The reduction box 53 is connected to the transmission member 443 of the motor transmission assembly 44 in a transmission manner. The reduction box 53 can increase the output torque of the driving mechanism 50. In other embodiments, the driving mechanism 50 may also include only the driving motor 51.

[0069] The driving mechanism 50 is in transmission connection with the transmission member 443 , so that the transmission member 443 drives the rotating seat 441 to rotate. Specifically, the output gear of the driving mechanism 50 can mesh with the transmission member 443 .

[0070] Please continue reading Figure 4 and Figure 5 In this embodiment, the smart lock 1 further includes a controller 60 and a first switch 70. The first switch 70 is arranged on the rotation path of the motor transmission assembly 44 and is electrically connected to the controller 60 and the driving mechanism 50 so as to send a first stop signal when the motor transmission assembly 44 drives the bolt assembly 33 to extend to the maximum position. The controller 60 controls the driving mechanism 50 to stop running according to the first stop signal. Among them, the first switch 70 can indicate the maximum position of the bolt assembly 33. The first switch 70 is arranged on the rotation path of the transmission paddle 445 so that the rotation of the transmission paddle 445 can offset the first switch 70, thereby stopping the driving mechanism 50 from running, avoiding the damage of the driving motor 51 caused by the inability of the driving mechanism 50 to drive the bolt assembly 33 to extend, and extending the service life of the driving mechanism 50. In this embodiment, the first switch 70 is a contact switch. In other embodiments, the first switch 70 can also be an induction switch.

[0071] In this embodiment, the smart lock 1 also includes a second switch 80, the first switch 70 and the second switch 80 are spaced apart in the circumferential direction of the motor transmission assembly 44, and the second switch 80 is electrically connected to the controller 60 and the drive mechanism 50, so as to send a second stop signal when the motor transmission assembly 44 drives the bolt assembly 33 to retract to the maximum position, and the controller 60 controls the drive mechanism 50 to stop running according to the second stop signal. The second switch 80 can indicate the maximum position of the bolt assembly 33 retracted, and the second switch 80 is arranged on the rotation path of the transmission paddle 445, so that the rotation of the transmission paddle 445 can offset the second switch 80, so that the drive mechanism 50 stops running, avoiding the damage of the drive motor 51 caused by the inability of the operation of the drive mechanism 50 to drive the bolt assembly 33 to retract, and extending the service life of the drive mechanism 50. In this embodiment, the second switch 80 is a contact switch. In other embodiments, the second switch can also be an induction switch.

[0072] See also Fig.13In this embodiment, the smart lock 1 further includes a second base 90, the first base 10 and the second base 90 are disposed on opposite sides of the lock body 30, and the first base 10 and the second base 90 are symmetrically disposed about the central axis of the lock body 30, wherein the central axis of the lock body 30 refers to the central axis of the lock body 30 along the length direction D1 of the panel 314, and is also the axis of the inner sleeve 319 and the outer sleeve 318. The first base 10 and the second base 90 are symmetrically disposed about the central axis of the lock body 30, so that the overall structure of the smart lock 1 is symmetrical and concise, and the appearance consistency of the smart lock 1 is improved. The smart lock 1 may also include a second cover plate (not shown), which can be covered on the second base 90, further improving the appearance consistency of the smart lock 1.

[0073] Please continue reading Figures 4 to 6 , the smart lock 1 also includes a detection switch (not shown), which is electrically connected to the drive motor 51 of the drive mechanism 50 to detect the current in the drive motor 51, and judge whether the drive motor is blocked by the current, so as to confirm whether the smart lock 1 is suitable for left-opening doors or right-opening doors, and whether the smart lock 1 is installed correctly. Specifically, after installation, when used for the first time, the drive motor 51 starts to work, and the detection switch detects the current in the drive motor. When the current is detected to be significantly increased, it means that the drive motor 51 is blocked, and the smart lock 1 is installed incorrectly. For example, if the door leaf on which the smart lock 1 is installed is a left-opening door, the smart lock 1 is suitable for right-opening doors. When the current is detected to be relatively stable, it means that the drive motor 51 is not blocked, and the smart lock 1 is installed correctly. For example, if the door leaf on which the smart lock 1 is installed is a left-opening door, the smart lock 1 is suitable for left-opening doors.

[0074] In summary, the smart lock 1 provided by the present invention includes a first base 10, a lock body 30, a transmission mechanism 40 and a driving mechanism 50. The lock body 30 includes a lock shell 31 and a lock tongue assembly 33. The lock shell 31 is connected to the first base 10. The lock tongue assembly 33 is movably arranged on the lock shell 31 and can be extended or retracted relative to the lock shell 31; the transmission mechanism 40 includes a lock tongue toggle member 42, a motor transmission assembly 44 and a knob shaft 46. The lock tongue toggle member 42 is rotatably arranged on the lock shell 31 and is transmission-connected to the lock tongue assembly 33. The motor transmission assembly 44 is rotatably arranged on the first base 10, and the knob shaft 46 is penetrated by the lock tongue toggle member 42 and the motor transmission assembly 44; the driving mechanism 50 is transmission-connected to the motor transmission assembly 44 to drive the motor transmission assembly 44 to rotate, and the motor transmission assembly 44 drives the lock tongue toggle member 42 to rotate through the knob shaft 46. In this way, the motor transmission assembly 44 can be driven to rotate by the driving mechanism 50, and the motor transmission assembly 44 can then drive the lock tongue toggle member 42 to rotate through the knob shaft 46, thereby driving the lock tongue assembly 33 to extend or retract relative to the lock shell 31, thereby realizing the electric locking or unlocking of the smart lock 1; the lock tongue toggle member 42 can also be driven to rotate by manually rotating the knob shaft 46, thereby realizing the mechanical locking or unlocking of the smart lock 1, wherein the smart lock 1 can be applied to left-door or right-door opening scenarios to meet different door opening requirements; since the knob shaft 46 passes through the lock tongue toggle member 42 and the motor transmission assembly 44, the lock tongue toggle member 42 and the motor transmission assembly 44 are arranged along the axial direction of the knob shaft 46, thereby reducing the space occupied by the lock tongue toggle member 42 and the motor transmission assembly 44, realizing the miniaturization of the smart lock 1, and improving the convenience of transportation and assembly of the smart lock 1.
