[0033] In some embodiments, the smart door lock may include a lock body and a status detection device. The lock body may include a collection of components capable of performing basic door lock functions (such as the extension and retraction of the lock tongue), such as a bolt assembly, lock cylinder, handle, and power supply. The status detection device is used to detect the open / closed state of the door lock. Generally, the open / closed state of the door lock is determined by the extension and retraction state of the lock tongue. For example, the extended state of the lock tongue can be defined as the closed state, and the retracted state can be defined as the open state. The status detection device detects the open / closed state by installing a magnet 3 and a light-shielding plate 11 on the component driving the extension and retraction of the lock tongue, and fixing two magnetic sensors 1 and two photoelectric sensors 2. It utilizes the characteristic that the positions of the magnet 3 and the light-shielding plate 11 change when the component driving the extension and retraction of the lock tongue is activated. The status detection device may include a magnetic sensor 1, a photoelectric sensor 2, a magnet 3, a toggle block 4, a follower 5, and a control unit. The magnetic sensor 1 may be a Hall sensor. The aforementioned magnetic sensor 1 can be used to sense changes in the strength of the surrounding magnetic field. The aforementioned magnet 3 can be located on the aforementioned lever 4, and the aforementioned driven member 5 can be provided with a light-shielding plate 11. The aforementioned magnet 3 can be a cylindrical magnet, without specific limitation. The aforementioned light-shielding plate 11 can be a wall-like structure protruding from the surface of the aforementioned driven member 5. The aforementioned lever 4 can be a combination of a frustum and a cylinder, with the cylinder connected to the smaller circular surface of the frustum. The aforementioned cylinder and the aforementioned frustum can be an integral structure. The aforementioned driven member 5 is similar to a gear structure, hollow inside with serrated outer edges, and the aforementioned light-shielding plate 11 is disposed on the side of the aforementioned driven member 5, as can be seen here. Figure 1The driven member 5 can establish a transmission relationship with the drive motor inside the door lock. For example, a gear can be installed on the motor, and the gear can mesh with the sawtooth on the outer edge of the driven member 5. The toggle block 4 can be installed in the hollow part of the driven member 5, and the driven member 5 can establish a transmission relationship with the toggle block 4. For example, protruding structures can be provided on the toggle block 4 and the driven member 5 respectively, so that when the driven member 5 rotates, the toggle block 4 and the protruding structures on the driven member 5 will contact each other, thereby allowing the driven member 5 to drive the toggle block 4 to rotate. The toggle block 4 can serve as a structure that establishes a transmission relationship with the bolt. For example, it can be set so that when the toggle block 4 does not rotate, the smart door lock is in the locked state (i.e., the bolt is extended), and when the toggle block 4 rotates 90°, the smart door lock is in the unlocked state (i.e., the bolt is retracted). The driven member 5 can drive the toggle block 4 to rotate back and forth through the protruding structures. Simultaneously, it can be configured that when the smart lock is in the locked state, one of the two magnetic sensors 1 can detect the magnet 3, while the two photoelectric sensors 2 cannot detect the light-shielding plate 11. Furthermore, the other of the two magnetic sensors 1 can be set to a designated position, where the position is such that the magnet 3 can be detected when the smart lock is in the unlocked state, i.e., when the toggle block 4 is rotated 90°. The toggle block 4 can rotate 90° from its initial position either clockwise or counterclockwise. Different rotation directions correspond to different application scenarios of the smart lock. For example, when the smart lock is used in a right-opening scenario, rotating the toggle block 4 90° counterclockwise from its initial position (i.e., when the smart lock is in the locked state) switches the smart lock to the unlocked state. It should be noted that the right-opening scenario refers to the lock being installed on the user's right-hand side when the user is facing the door from the outside; the opposite is the left-opening scenario. The aforementioned left-opening door scenario means that when the user is facing the door from the outside, the door lock is installed on the user's left. Since the smart door lock needs to frequently switch between unlocked and locked states, the aforementioned toggle 4 needs to rotate reciprocally, and this requires the aforementioned driven member 5 to drive it. Therefore, the smart door lock motor can be configured to have forward and reverse rotation capabilities, thus indirectly driving the toggle 4 to rotate forward and reverse via the aforementioned driven member 5. The aforementioned control unit can control the aforementioned motor to rotate forward and reverse. Both the aforementioned magnetic sensor 1 and the aforementioned photoelectric sensor 2 can communicate with the aforementioned control unit. The aforementioned magnetic sensor 1 can sense changes in the magnetic field strength of the aforementioned magnet 3, and can then send a signal to the aforementioned control unit based on these changes. The aforementioned control unit can be a microcontroller or other logic controller, without specific limitations. It should be noted that the aforementioned control unit is not shown in the accompanying drawings.Compared to relying solely on photoelectric sensors for smart lock status detection, the advantage of using a combination of the aforementioned magnetic sensor 1 and photoelectric sensor 2 lies in the fact that the magnetic sensor 1 can be a Hall sensor, which is typically smaller than a photoelectric sensor. This reduces the space occupied within the smart lock, thereby improving its internal space utilization. Specifically, on the smart lock's circuit board, which highly integrates various electronic components, the space saved by using the Hall sensor allows for the integration of even more electronic components.

[0034] In some embodiments, the magnet 3 may be located on the toggle block 4. The light-shielding plate 11 may be located on the driven member 5. Since the control unit can determine the positions of the magnet 3 and the light-shielding plate 11 based on the signals transmitted by the magnetic sensor 1 and the photoelectric sensor 2 respectively, when the magnet 3 is located on the toggle block 4 and the light-shielding plate 11 is located on the driven member 5, the control unit can determine the positions of the toggle block 4 and the driven member 5 based on the signals transmitted by the magnetic sensor 1 and the photoelectric sensor 2 respectively, and thus determine the open / closed state of the smart door lock.

[0035] Optionally, such as Figure 1 As shown, the aforementioned state detection device may further include a circuit board 10. The circuit board 10 can be used to carry the aforementioned magnetic sensor 1 and the aforementioned photoelectric sensor 2. The two magnetic sensors 1 can be arranged along the same circumference on the circuit board 10. The two magnetic sensors 1 can be distributed at 90° intervals along the same circumference. The reason for arranging the two magnetic sensors 1 at 90° intervals along the same circumference is that the toggle block 4 reciprocates within a 90° range, and the magnet 3 on it also reciprocates accordingly. This arrangement is equivalent to placing the two magnetic sensors 1 at the starting and ending points of the reciprocating rotation of the magnet 3, respectively. That is, the two magnetic sensors 1 are used to sense the initial state of the toggle block 4 and its state after rotating 90°, respectively. The two magnets 3 can be arranged at 180° intervals along the same circumference. The purpose of this arrangement is that in the aforementioned right-opening door scene and the aforementioned left-opening door scene, only one magnet 3 is needed for a single scene. The two photoelectric sensors 2 can be arranged along the same circumference on the circuit board 10. The two photoelectric sensors 2 mentioned above can be distributed at 90° intervals along the same circumference. Both the magnetic sensor 1 and the photoelectric sensor 2 are distributed circumferentially because the magnet 3 and the light-shielding plate 11 move in a circular motion during use. This arrangement ensures that both the magnetic sensor 1 and the photoelectric sensor 2 can accurately sense the magnet 3 and the light-shielding plate 11.

[0036] Optionally, such as Figure 2As shown, the aforementioned lever 4 can be coaxially assembled with the aforementioned driven member 5. This is because the driven member 5 can be a hollow structure. The hollow portion of the driven member 5 can be used to accommodate the aforementioned lever 4.

[0037] Optionally, such as Figure 1 As shown, the aforementioned lever 4 may be equipped with a drive shaft 6 and a lever head 8. The lever head 8 may be a frustum-shaped structure. The drive shaft 6 may be a cylindrical structure. The drive shaft 6 may be vertically positioned on the smaller circular area side of the lever head 8. The drive shaft 6 may be used to directly link with the latch of the smart door lock to ensure that the lever 4 can accurately indicate the extension and retraction state of the latch by rotating the angle. The other side of the lever head 8 (i.e., the larger circular surface of the frustum-shaped structure) may be equipped with a mounting groove 9. The aforementioned magnet 3 may be installed in the mounting groove 9. The aforementioned magnet 3 may be installed in the mounting groove 9 by an interference fit, or by using clips, glue, or other installation methods. No specific limitation is made here, as long as the aforementioned magnet 3 can be installed in the mounting groove 9.

[0038] Optionally, such as Figure 1 As shown, the aforementioned dial head 8 may be provided with a paddle 7. The paddle 7 may be located on the side of the dial head 8 with a larger circular area. The paddle 7 may be a fan-shaped structure protruding from the side of the dial head 8 with a larger circular area. The paddle 7 and the dial head 8 may be an integral structure to ensure the strength of the connection between the dial head 8 and the paddle 7. The paddle 7 may serve as a transmission structure between the aforementioned lever block 4 and the aforementioned driven member 5. The transmission structure may involve a protruding structure (not shown in the figures) inside the driven member 5. When the driven member 5 rotates, the protruding structure contacts the paddle 7, thereby driving the lever block 4 to rotate.

[0039] Optionally, the light-shielding plate 11 can be pre-positioned vertically on one side of the driven member 5. This side can be the side facing the circuit board 10. It is positioned facing the circuit board 10 because the photoelectric sensor 2 is mounted on the circuit board 10. Pre-positioning the light-shielding plate 11 on this side allows the photoelectric sensor 2 to detect it.

[0040] Optionally, such as Figure 3As shown, there may be a gap between each of the aforementioned light-shielding plates 11. The two light-shielding plates 11 may be arranged at a 180° interval along the same circumference. The two light-shielding plates 11 may be of equal size, and their length may be set to the arc length between the two photoelectric sensors 2. This is because the two photoelectric sensors 2 may be arranged at a 90° interval along the same circumference. The purpose of arranging the two light-shielding plates 11 in this manner is that when one of the light-shielding plates 11 completely passes through the sensing range of one of the photoelectric sensors 2, the driven member 5 rotates exactly 90°. Furthermore, regardless of whether the light-shielding plate 11 rotates 90° counterclockwise or clockwise, one of the light-shielding plates 11 is always adjacent to the photoelectric sensor 2.

[0041] When the state of a smart lock changes, the positional relationship between mechanical structures usually changes. For example, during the locking process, the extension of the bolt is involved from the overall structure of the smart lock. Currently, a transmission relationship is generally established between the state detection device and the bolt, with the drive motor of the state detection device simultaneously driving the extension and retraction of the bolt. This method can ensure that the movements of the state detection device and the bolt are synchronized as much as possible, thereby improving the detection accuracy of the state detection device. However, the extension and retraction of the bolt is limited; when it reaches a predetermined state, a limiting structure constrains its movement. Under normal circumstances, when the bolt is fully extended, the sensor on the state detection device detects the corresponding sensing source and sends a signal to the control unit, which then sends a stop signal to the motor. However, because the sensor's sensitivity may be affected by external interference, causing untimely signal transmission, the control unit of the state detection device may not send a stop signal to the motor in time when the bolt is fully extended, causing the motor to continue outputting torque without rotating. This could potentially damage the motor. To address this problem, this disclosure proposes the following transmission structure.

[0042] Optionally, such as Figure 4As shown, the aforementioned state detection device may further include a transmission structure. This transmission structure transmits the driving force of the motor 12 to the state detection device. The transmission structure may include a drive shaft 13, a drive wheel 14, a belt, and a driven wheel 15. The drive shaft 13 connects the motor 12 of the state detection device and the drive wheel 14. One end of the drive shaft 13 may be provided with an anti-slip ridge 17. The anti-slip ridge 17 is a strip-shaped protrusion arranged along the axial direction of the drive shaft 13. There may be two anti-slip ridges 17. The anti-slip ridges 17 ensure an anti-slip effect when the drive shaft 13 and the drive wheel 14 are connected, preventing relative slippage between the drive shaft 13 and the drive wheel 14 during rotation. It should be noted that a greater number of anti-slip ridges 17 results in a better anti-slip effect, but increases the difficulty of the manufacturing process. Therefore, providing two ridges satisfies the anti-slip effect without excessively increasing the manufacturing difficulty. A connecting hole matching the end of the drive shaft 13 where the anti-slip ridge 17 is located may be provided in the center of the drive wheel 14. The aforementioned connecting hole may be provided with an anti-slip groove that matches the aforementioned anti-slip rib 17. The surface of the aforementioned anti-slip rib 17 may be in close contact with the surface of the aforementioned anti-slip groove. The aforementioned drive shaft 13 may be securely connected to the aforementioned drive wheel 14 through the aforementioned connecting hole. The outer side of the aforementioned drive wheel 14 may be provided with a first belt groove 18. The aforementioned driven wheel 15 may be located on the aforementioned driven member 5 and may be integrally formed with the aforementioned driven member 5. The outer side of the aforementioned driven wheel 15 may be provided with a second belt groove 16. The aforementioned belt may connect the aforementioned drive wheel 14 and the aforementioned driven wheel 15 through the aforementioned first belt groove 18 and the aforementioned second belt groove 16. The aforementioned drive wheel 14 and the aforementioned driven wheel 15 may be arranged in the same plane so that the aforementioned belt is not easily slipped out of the aforementioned first belt groove 18 and the aforementioned second belt groove 16. The aforementioned belt is constructed to be in close contact with the aforementioned first belt groove 18 and the aforementioned second belt groove 16 simultaneously. The aforementioned belt may be made of a soft rubber material and has a certain degree of elasticity. The purpose of connecting the drive wheel 14 and the driven wheel 15 with the belt is that when the drive wheel 14 rotates, the driven wheel 15 will also rotate at the same linear velocity. When the rotation of the driven wheel 15 is restricted and cannot continue to rotate, the motor 12 can utilize the characteristics of belt drive to cause the belt and the drive wheel 14 to slip, thus maintaining rotation and reducing the possibility of damage to the motor 12. Both the first belt groove 18 and the second belt groove 16 can have a U-shaped cross-section to prevent the belt from slipping out. It should be noted that the belt is not shown in the accompanying drawings.

[0043] The above-mentioned optional embodiments can serve as the inventive point of this disclosure, solving the "technical problem of easy damage to the motor of the state detection device". The specific reason for the easy damage to the motor of the state detection device is that when the state of the smart lock changes, the positional relationship between the mechanical structures usually changes. For example, during the locking process of a smart lock, from the perspective of the overall structure of the smart lock, the extension of the bolt is involved. Currently, a transmission relationship is generally established between the state detection device and the bolt, with the drive motor of the state detection device simultaneously driving the extension and retraction of the bolt. This method can ensure that the movements of the state detection device and the bolt are synchronized as much as possible, thereby improving the detection accuracy of the state detection device. Furthermore, the extension and retraction of the bolt is limited; when it extends to a predetermined state, a limiting structure constrains the movement of the bolt. Under normal circumstances, when the bolt is fully extended, the sensor on the state detection device detects the corresponding sensing source and sends a signal to the control unit, which then sends a stop signal to the motor. However, because the sensor's sensitivity may be affected by external interference, causing untimely signal transmission, the control unit of the status detection device may not send a stop signal to the motor in time when the latch is extended to the correct position. As a result, the motor may continue to output torque but cannot rotate, potentially causing damage. Avoiding this situation, where the motor continuously outputs torque but cannot rotate, reduces the likelihood of motor damage. To achieve this, this disclosure provides another transmission structure. Using this transmission structure, when the driven wheel's rotation is restricted and cannot continue, the belt drive's characteristics cause the belt and the drive wheel to slip, maintaining rotation and thus reducing the possibility of motor damage.

[0044] Optionally, the smart lock housing may be equipped with a reset button. This reset button can communicate with the control unit. The reset button can transmit signals to the control unit, causing the control unit to instruct the smart lock's motor to rotate in both directions. In use, the user presses and holds the reset button, and the motor module begins to rotate. Once the smart lock's status detection and drive device has completed a full cycle of the smart lock's unlocking and locking states, the control unit can determine whether the smart lock body is installed in the right-opening scenario or the left-opening scenario.

[0045] The embodiments disclosed above have the following beneficial effects: the utilization rate of the internal space of the smart lock is improved through some embodiments of the present disclosure. Specifically, the reason for the low utilization rate of the internal space of the smart lock is that the status detection device contains a large number of photoelectric sensors, and the photoelectric sensors are generally large in size. Based on this, some embodiments of the present disclosure provide a smart lock, which includes a lock body and a status detection device, wherein the status detection device includes a magnetic sensor, a photoelectric sensor, a magnet, a follower, a toggle block, and a control unit, wherein the magnet is located on the toggle block, and the follower is provided with a light-shielding plate; the number of the magnetic sensor and the number of the photoelectric sensor are both at least two; the magnetic sensor is configured to sense the magnet, the photoelectric sensor is configured to sense the light-shielding plate, and both the magnetic sensor and the photoelectric sensor are communicatively connected to the control unit. The volume of the magnetic sensor is smaller than that of the photoelectric sensor, thereby improving the utilization rate of the internal space of the smart lock.

[0046] Figure 5 This is a schematic diagram of the structure of a gate according to some embodiments of this disclosure. Figure 5 Includes the door body 19 and the smart door lock 20.

[0047] In some embodiments, the door includes a door body 19 and, as shown in the figure, a door with a door body 19 and ... Figure 1-3 The corresponding embodiments describe the smart door lock 20. The smart door lock 20 is mounted on the door body 19.

[0048] The above embodiments of this disclosure have the following beneficial effects: the door provided by the embodiments of this disclosure improves the applicability of smart door locks. The reason for the low applicability of smart door locks is that some users may choose to purchase smart door locks online to pursue cost-effectiveness. However, some online platform merchants may not offer on-site installation services. This requires users to install it themselves or find a nearby professional to install it. Some users may consider that finding a nearby professional to install it will increase installation costs, which undoubtedly contradicts the initial intention of pursuing cost-effectiveness. Self-installation may not achieve the desired installation effect, and it is also necessary to consider whether the holes on the door being used match the smart door lock. This may cause some users to abandon the idea of ​​using smart door locks due to installation problems, thus leading to the problem of low applicability of smart door locks. Some embodiments of this disclosure provide a door, the door including a door body and such as... Figure 1-3 The smart lock described in the corresponding embodiments is installed on the door body. The smart lock is already installed on the door. Users do not need to purchase a separate smart lock and hire professionals for installation, thus avoiding problems such as mismatched holes that may occur during smart lock installation. This improves the applicability of the smart lock.
