[0052] Combine the following Figures 1 to 11 , describing the smart door lock, front panel replacement method and smart door of the embodiments of the present invention.

[0053] According to an embodiment of the present invention, on the one hand, a smart door lock is provided. Figure 1 As shown, the smart door lock is suitable for being installed on a door panel 1. Specifically, the smart door lock includes a rear panel 2, a front panel 3, and a lock body. Specifically, as Figure 1As shown, the rear panel 2 is arranged on the inner side 101 of the door panel 1, and the rear panel 2 is provided with a control module 201 and a motor 202. The motor 202 is electrically connected to the control module 201, and the motor 202 is used to drive the lock body to open or close.

[0054] like Figure 1 As shown, the front panel 3 is disposed on the outer side 102 of the door panel 1, and as shown in Figure 2 As shown, the front panel 3 is connected to the door panel 1 through a quick-release structure 4. The front panel 3 is provided with a biometric identification device and an intelligent detection device, and the control module 201 provided on the rear panel 2 is electrically connected to the biometric identification device. Specifically, the front panel 3 is also provided with a front panel mainboard 301, and the front panel mainboard 301 is electrically connected to the biometric identification device. Fig.10 As shown, the front panel mainboard 301 is electrically connected to the control module 201 through the connecting line 8, so that the front panel mainboard 301 acts as a signal transfer station to realize the information interaction between the front panel 3 and the rear panel 2. Among them, the connecting line 8 adopts a quick-connect connector, which cooperates with the corresponding docking socket, so as to facilitate quick connection and disconnection, and facilitate the disassembly and assembly of the front panel 3 and the rear panel 2. The docking interface on the control module 201 is a universal interface, compatible with all mainboard interfaces, so as to adapt to the new front panel 3. Optionally, the control module 201 located on the rear panel 2 is electrically connected to the intelligent detection device, specifically, the intelligent detection device is electrically connected to the front panel mainboard 301, and the front panel mainboard 301 is electrically connected to the control module 201 through the connecting line 8. It should be noted that the iterative update of the biometric recognition device and the intelligent detection device is relatively fast. If new technology updates are required, users only need to replace the front panel 3 alone to experience new technologies and new products.

[0055] The lock body (not shown in the figure) is arranged in the door panel 1, and the lock body is arranged between the rear panel 2 and the front panel 3. The lock body can be opened and locked under the drive of the motor 202. This part is conventional technology and will not be described here. In addition, as an embodiment, Figure 1 As shown, the rear panel 2 may also be provided with a handle 206, and the lock body may be opened and locked by turning the handle 206. In addition, the rear panel 2 is also provided with a battery 203, a display screen 204 and a physical button 205, which are convenient for users to use and operate. Among them, the battery 203 adopts a detachable lithium battery. It should be noted that the control module 201, the motor 202, the battery 203, the display screen 204, the physical button 205 and the handle 206 are all common components of door locks, and the technology is relatively mature, so the rear panel 2 does not need to be updated.

[0056] With such a configuration, the front panel 3 integrates components that are updated quickly, such as biometric devices and intelligent detection devices, and the rear panel 2 integrates common components, such as the control module 201 and the motor 202. If the new technology of the smart door lock is updated, the front panel 3 can be quickly disassembled and assembled through the quick-release structure 4, so that it is easy to replace the front panel 3 of different styles and functions, and realize the functional upgrade and style update of the door lock. Compared with replacing the entire door lock, there is no need to replace the rear panel 2 and the lock body, which is easy to operate, greatly reducing the replacement cost, reducing the user's burden, and improving the user experience. There is no need for installation personnel to come to the door, and users can replace it by themselves. In addition, it can also improve the competitiveness of the product, and the door lock manufacturer can also sell the front panel 3 to the user separately, and provide the recycling service of the original front panel 3, providing more convenience for the users of the smart door lock and promoting the development of the smart door lock industry.

[0057] In some embodiments of the present invention, the quick-release structure 4 includes a snap-on component 401 and a slot 402. Specifically, the snap-on component 401 is connected to the rear panel 2 or the door panel 1, and the snap-on component 401 extends out of the outer side surface 102 of the door panel 1. The slot 402 is provided on the side of the front panel 3 facing the door panel 1, and the snap-on component 401 is snapped into the slot 402. With such a configuration, the snap-on component 401 and the slot 402 cooperate with each other, so that the installation process of the front panel 3 becomes simple and quick. The user only needs to align the snap-on component 401 with the slot 402 and push it in to complete the connection. When removing, the snap-on component 401 is pulled out of the slot 402 without the use of complicated tools or cumbersome operations. The design of the quick-release structure 4 greatly shortens the installation time and improves the assembly efficiency. In addition, if Figure 2 As shown, the number of the clamping member 401 and the clamping slot 402 is at least two, thereby improving the reliability and stability of the connection. Of course, in other embodiments, the quick-release structure 4 includes but is not limited to the clamping method, and can also adopt a magnetic suction method, a slider and a slide groove matching method, etc., and make adaptive adjustments to achieve quick disassembly and assembly of the front panel 3.

[0058] Further, in some embodiments of the present invention, Figure 4 As shown, the card slot 402 includes a first slot body 4021 and a second slot body 4022 that are connected. The size of the first slot body 4021 along the first direction is W1, and the size of the second slot body 4022 along the first direction is W2, wherein W2<W1, thereby forming a special-shaped slot structure.

[0059] like Figure 5 As shown, the clamping member 401 includes a clamping portion 4011 and a stopper 4012 connected to each other, the size of the clamping portion 4011 along the first direction is W3, and the size of the stopper 4012 along the first direction is W4, wherein W3≤W2, and W2≤W4≤W1. Specifically, the clamping member 401 uses a special-shaped screw, the diameter of the clamping portion 4011 is W3, and the diameter of the stopper 4012 is W4.

[0060] When installing a new panel, Figure 6 As shown, align the second groove 4022 on the front panel 3 with the stopper 4012 of the clamping member 401 and push it in, then push the front panel 3 downward until the clamping member 4011 slides into the first groove 4021, and finally completes the clamping and fixing of the front panel 3. When removing the front panel 3, the reverse operation is sufficient. In this way, the front panel 3 can be fixed by using the special-shaped groove and the special-shaped clamping member to cooperate with each other, and the stopper 4012 is used to further improve the connection reliability between the front panel 3 and the door panel 1.

[0061] In some embodiments of the present invention, Figure 2 As shown, the smart door lock also includes a connector 6 and a connecting sleeve 7. The connector 6 is connected to the rear panel 2, and the connector 6 is inserted into the door panel 1. The connecting sleeve 7 is arranged in the door panel 1, and one end of the connecting sleeve 7 is sleeved on the connector 6, and the other end is sleeved on the clamping member 401. Specifically, the connecting sleeve 7 adopts a threaded tube, and the connector 6 and the clamping member 401 are respectively provided with matching external threads to thread the connecting sleeve 7 with the connector 6 and the clamping member 401, respectively. With such a configuration, the clamping member 401 can be easily installed by cooperating with the connector 6 and the connecting sleeve 7, and the operation is simple. In addition, as Figure 2 As shown, an adapter plate 9 is also provided on the outer side of the door panel 1 so as to be connected with the front panel 3 .

[0062] Further, in some embodiments of the present invention, Figure 1 As shown, the smart door lock also includes a locking structure 5, which is used to lock or release the front panel 3 and the door panel 1, thereby preventing the detachable front panel 3 from being removed outdoors at will, thereby ensuring the reliability of the smart door lock.

[0063] Specifically, the locking structure 5 includes a threaded hole 501 and a locking member 502. Figure 4 As shown, the threaded hole 501 is arranged on the side of the front panel 3 facing the door panel 1. Figure 2As shown, the locking member 502 is screwed into the threaded hole 501, and the locking member 502 is inserted into the door panel 1 and extends out of the inner side 101 of the door panel 1. Specifically, the locking member 502 is a screw. When installing a new panel, after the front panel 3 is fixed to the door panel 1 through the quick-release structure 4, the screw is passed through the door panel 1 from the inner side of the door panel 1 and screwed into the threaded hole 501 to lock the front panel 3 and the door panel 1, so that the front panel 3 cannot be removed from the outside. When removing the front panel 3, the screw needs to be unscrewed from the inner side of the door panel 1, the front panel 3 and the door panel 1 are loosened, and then the front panel 3 is removed. In addition, the mirror nail 503 can also be installed at the end of the screw to more reliably lock the front panel 3. Such a setting is simple to operate and easy to disassemble. Of course, in other embodiments, the locking structure 5 includes but is not limited to the threaded hole 501 and the locking member 502, and can also adopt a pin shaft and a pin hole and other methods, and make adaptive adjustments to achieve the locking of the front panel 3.

[0064] In some embodiments of the present invention, the biometric identification device includes at least one of a face recognition module 303, a palm vein module 304, a finger vein module 305, a fingerprint module 306, and a numeric keypad touch panel 308. The intelligent detection device includes at least one of a non-contact detection sensor and a cat's eye module 302, wherein the non-contact detection sensor includes but is not limited to a radar 307, a passive infrared detector (Passive Infrared Detector, PIR), etc. In this way, the user can select each module of the front panel 3 according to the needs, realize a variety of unlocking methods, optimize the user's experience, and improve the safety and reliability of the smart door lock.

[0065] In summary, the embodiment of the present invention provides a smart door lock, wherein the lock body is installed in the door panel 1, the rear panel 2 is installed on the inner side of the door panel 1, and the front panel 3 is installed on the outer side of the door panel 1. The front panel 3 is conveniently disassembled and assembled quickly by the quick-release structure 4, and the front panel 3 is locked with the door panel 1 by the locking structure 5. Specifically, Fig.10As shown, the rear panel 2 integrates the common components of the door lock, and the rear panel 2 includes a control module 201, a motor 202, a battery 203, a display screen 204, a physical button 205 and a handle 206. Among them, the motor 202, the battery 203, the display screen 204 and the physical button 205 are all connected to the control module 201 for communication to achieve information interaction. The front panel 3 integrates the door lock components that are updated faster, and the front panel 3 includes a front panel mainboard 301, a cat's eye module 302, a face recognition module 303, a palm vein module 304, a finger vein module 305, a fingerprint module 306, a radar 307 and a numeric keypad touch panel 308. Among them, the cat's eye module 302, the face recognition module 303, the palm vein module 304, the finger vein module 305, the fingerprint module 306, the radar 307 and the numeric keypad touch panel 308 are all connected to the front panel mainboard 301 for communication to achieve information interaction. The front panel mainboard 301 is electrically connected to the control module 201 via a connecting wire 8 to realize information exchange between the front and rear panels. The connecting wire 8 is electrically connected to a corresponding socket using a quick-plug connector.

[0066] In this way, the smart door lock can be disassembled and replaced by the front panel 3 alone, and the rear panel 2 and the lock body do not need to be replaced, which is convenient for upgrading the style and function of the front panel 3. Figure 2 As shown, when removing the front panel 3, you only need to unscrew the locking piece 502 from the inside of the door panel 1, then push the front panel 3 upwards, pull the card connector 401 out of the card slot 402, and then remove the front panel 3, and then pull out the connecting wire 8 from the docking socket to complete the disassembly. When installing a new front panel 3, you need to first insert the connecting wire 8 into the corresponding docking socket, then align the special-shaped slot opening on the front panel 3 with the position of the card connector 401 and push it in, push the front panel 3 downwards to fix the front panel 3, and then screw on the locking piece 502 from the inside of the door panel 1 to complete the installation of the new panel. Its operation is relatively simple, and users can quickly replace it by themselves.

[0067] According to an embodiment of the present invention, on the other hand, a method for replacing a front panel is provided for controlling the smart door lock in the above-mentioned embodiments. Figure 7 As shown in the figure, the method for replacing the front panel includes:

[0068] Establishing a communication connection with at least the biometric identification device of the replaced front panel 3;

[0069] After the communication connection is completed, the biometric identification device is controlled to perform self-test and send out the self-test result.

[0070] In this way, when a new front panel 3 is replaced, the control module 201 on the rear panel 2 will establish a communication connection with the biometric device on the replaced front panel 3. After the signal connection is completed, the entire lock will automatically perform a full-function self-test, that is, each functional module of the replaced front panel 3 will be automatically run once, for example, the face recognition module 303 will be turned on, and it will be determined whether the face recognition module 303 is working properly. After the full-function self-test is completed, the self-test results can be sent to the user. Specifically, the user can download the APP (Application) client on a terminal such as a mobile phone to receive the self-test results.

[0071] In addition, as an implementation mode, when a new front panel 3 is replaced, the control module 201 on the rear panel 2 will establish a communication connection with the intelligent detection device on the replaced front panel 3. After the signal connection is completed, each module in the intelligent detection device of the replaced front panel 3 will be automatically operated once, for example, the cat's eye module 302 will be turned on, a picture will be taken once, and it will be determined whether the cat's eye module 302 is working normally. After all self-tests are completed, the self-test results will be sent to the user.

[0072] Further, in some embodiments of the present invention, Figure 8 As shown, the method for replacing the front panel 3 also includes:

[0073] When the self-test result is abnormal, an abnormal prompt message and / or abnormal adjustment message is issued.

[0074] Specifically, if the self-test results are all normal, the user can start using the new smart door lock. If the self-test results are abnormal, abnormal prompt information and abnormal adjustment information can be sent to the user. For example, the abnormal prompt information includes the name of the abnormal module, and the abnormal adjustment information includes optional problem solutions, so that the user can easily know which module has a problem and how to troubleshoot and solve the problem. Then the user can solve the problem by himself according to the prompt, or choose to report a repair. In addition, the smart door lock can connect to WiFi (Wireless Fidelity). After successfully connecting to WiFi, the APP client will obtain the latest firmware information of each functional module of the front panel 3 from the server. If there is a firmware update, it will be pushed to the user through the APP client. The user can choose whether to update the firmware of each functional module of the front panel 3 according to the latest firmware information.

[0075] Optionally, in some embodiments of the present invention, Fig. 9 As shown, step: establishing a communication connection with the biometric identification device of the replaced front panel 3 includes:

[0076] Obtaining identification information of the replaced biometric device;

[0077] Based on the identification information, a communication connection is established with the replaced biometric device.

[0078] Specifically, the identification information includes hardware coding and firmware version number, and for each module, its hardware coding and firmware version number are corresponding. The connecting line 8 adopts UART (Universal Asynchronous Receiver / Transmitter) serial communication line. The control module 201 is connected to the front panel mainboard 301 through the UART serial communication line. The front panel mainboard 301 integrates the communication lines of each module on the front panel 3, so that the control module 201 can interact with each module on the front panel 3 to obtain the firmware version number of the corresponding module. Since the firmware version number corresponds to the corresponding hardware coding, after interaction, the hardware coding and firmware version number of each module can be updated to the APP client on the user's mobile phone. Each module of the front panel 3 has its own main control chip, which can communicate with the control module 201 through the serial port, wherein the front panel mainboard 301 is responsible for transferring the communication lines of each module, thereby completing the signal connection and control of the control module 201 and each module on the front panel 3.

[0079] In addition, as an implementation mode, when a new front panel 3 is replaced, the control module 201 on the rear panel 2 will establish a communication connection with the intelligent detection device on the replaced front panel 3. Specifically, the control module 201 located on the rear panel 2 obtains the identification information of each module in the replaced intelligent detection device, including but not limited to the hardware code and the firmware version number. Based on the above identification information, the control module 201 establishes a communication connection with the intelligent detection device on the replaced front panel 3.

[0080] In summary, when the smart door lock is replaced with a new front panel 3, Fig.11As shown, the user needs to clear and reset the entire lock. After the reset operation, the control module 201 on the rear panel 2 automatically obtains the hardware code and firmware version number of each module on the front panel 3, and completes the signal connection and control. The specific method is that the control module 201 communicates with the front panel mainboard 301 through the UART serial communication line. The front panel mainboard 301 integrates the communication lines of each module on the front panel 3, so that the control module 201 can interact with each module on the front panel 3 to obtain the firmware version number of each module and the corresponding hardware code. After completing the signal connection, the entire lock will automatically perform a full-function self-test, that is, each functional module of the replaced front panel 3 will be automatically run once, for example, the cat's eye module 302 is turned on, a picture is taken, and it is determined whether the cat's eye module 302 is working normally. After the full-function self-test is completed, the self-test results can be sent to the user. If the self-test results are all normal, the user can start using the new smart door lock. If the self-test result is abnormal, the user will be sent abnormal prompt information and abnormal adjustment information to inform the user which module has a problem and how to troubleshoot and solve the problem, so that the user can solve the problem by themselves according to the prompts, or report the abnormality. After the abnormal problem is resolved, the user can start using the new smart door lock. The smart door lock can connect to WiFi. After successfully connecting to WiFi, the APP client will obtain the latest firmware information of each functional module of the front panel 3 from the server. If there is a firmware update, it will be pushed to the user through the APP client. The user can choose the firmware update of each functional module according to the latest firmware information.

[0081] According to an embodiment of the present invention, on the other hand, a smart door is provided, including a door panel 1 and a smart door lock installed on the door panel 1, wherein the smart door lock is configured as the smart door lock in each of the above embodiments. In this configuration, the front panel 3 integrates components that are updated quickly, such as a biometric device and an intelligent detection device, and the rear panel 2 integrates common components, such as a control module 201 and a motor 202. If the new technology of the smart door lock is updated, the front panel 3 can be quickly disassembled and assembled through the quick-release structure 4, so as to facilitate the replacement of the front panel 3 of different styles and functions, and realize the functional upgrade and style update of the door lock. Compared with replacing the entire door lock, there is no need to replace the rear panel 2 and the lock body, which is easy to operate, greatly reducing the replacement cost, reducing the burden on users, and improving the user experience. Moreover, there is no need for installation personnel to come to the door, and users can replace it by themselves. At the same time, it can also improve the competitiveness of the product. The manufacturer can also sell the front panel 3 to the user separately, and provide the recycling service of the original front panel 3, to provide more convenience for the users of the smart door lock and promote the development of the smart door lock industry. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effects of the above-mentioned smart door lock, so it will not be repeated here.

[0082] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
