[0002] With the rapid development of smart home technology, smart door locks, as an important part of home security, are increasingly valued for their safety, convenience and reliability. Most smart door locks on the market currently integrate multiple electronic unlocking methods such as password input, fingerprint recognition, and RFID card reading, which greatly enriches the user experience. However, while these smart door locks provide convenience, they also have some shortcomings.

[0003] In the prior art, some glass door locks often have a large gap between the main lock body and the secondary lock body in the closed state when locked. This results in that when the glass door is pushed by external force, the gap between the door is large enough for fingers to easily penetrate and contact the mechanical structure inside the lock, which may be unlocked by improper operation, posing a potential safety risk. In addition, some glass door locks completely drive the door lock structure through electronic components, and there is a risk of being unable to open the door after power failure. Although other glass door locks are equipped with a mechanical unlocking structure, it is often mechanically connected to the lock tongue, and there is still a risk of being pried open.

[0004] Therefore, it is imperative to redesign a smart glass door lock. Utility Model Content

[0038] The driving assembly 31 includes a driving motor 311, a driving gear 312, a toggle gear 313 and a tooth ruler 314. The driving gear 312 is connected to the output end of the driving motor 311. The toggle gear 313 is meshed with one side of the driving gear 312. A toggle member 3131 is provided on the toggle gear 313. The tooth ruler 314 is provided on one side of the toggle member 3131. A driving groove 3141 matching with the tooth ruler 314 is provided on the side of the toggle member 3131. The toggle gear 313 drives the tooth ruler 314 to move along the sliding assembly provided inside the frame 12 in the main lock body door through the cooperation between the toggle member 3131 and the driving groove 3141.

[0039] The lock tongue 32 is a semicircular structure, and one end of the lock tongue is located at the center of the semicircular structure. A lock tongue gear 321 is integrally formed at the end. The lock tongue gear 321 is arranged on a gear seat inside the main lock body door inner frame 12 and meshes with the tooth ruler 314. When locking the door, the other end of the lock tongue 32 passes through the lock tongue passing part of the main lock body door inner frame 12, passes through and cooperates with the lock buckle 42, and then passes through the lock tongue buckling part of the main lock body door inner frame 12 to complete the locking.

[0040] Each of the lock slot plates 41 is provided with a long adjustment slot 411 , and at least one threaded hole 421 is provided on both sides of the lock buckle 42 . The positions of the threaded holes 421 match the long adjustment slot 411 and are fixed by screw connection.

[0041] The multifunctional control module includes a video intercom component 5, a fingerprint sensing component 6, a touch doorbell component 7 and an emergency unlocking component 8. A single-chip microcomputer master control unit 121 is also provided in the frame 12 inside the main lock body door. The video intercom component 5, the fingerprint sensing component 6, the touch doorbell component 7 and the emergency unlocking component 8 are all electrically connected to the single-chip microcomputer master control unit 121; specifically, the video intercom component 5 is composed of an audio and video acquisition component, an audio and video processing component, and a communication component. The audio and video acquisition component includes a camera and a microphone. The camera is used to capture real-time video of visitors outside the door, and the microphone is used to collect the voice of the visitors. The audio and video processing component includes an audio and video encoder for compressing and encoding the collected audio and video signals to ensure stability and fluency in network transmission; the communication component includes communication methods such as WiFi or 4G, which is used to realize wireless connection between the smart door lock and the user's smart device.

[0042] The emergency unlocking component 8 is provided with a lock core 81, a trigger rod 82 and a power switch button 83. The lower end of the main lock body door outer frame 11 is provided with a lock hole. The lock core 81 is matched with the lock hole. The trigger rod 82 is arranged in the lock core 81. The power switch button 83 is arranged on one side of the inner end of the lock core 81. During emergency unlocking, the key rotates the lock core 81 to drive the trigger rod 82 to move upward and contact the power switch button 83. The power switch button 83 is connected to the single-chip microcomputer master control unit 121 and the drive motor 311 respectively through electrical signals.

[0043] The main lock body inner door frame 12 is provided with a door opening knob 122 and an inner door handle 123 on the outside. The door opening knob 122 is connected to the toggle gear 313, and the inner door handle 123 is used to open the indoor door.

[0044] The secondary lock body 2 is also provided with a secondary lock body door outer frame 21 to facilitate the user to open the glass door from the outside.

[0045] When the visitor presses the doorbell, the camera and microphone start working to collect the visitor's real-time audio and video signals. The visitor then selects a suitable unlocking method through the multi-functional control module, for example, obtaining authorization through fingerprint recognition. After successful verification, the single-chip microcomputer main control unit 121 sends an unlocking signal to the lock tongue drive module 3. First, the driving motor 311 in the lock tongue drive module 3 is started, driving the driving gear 312 to rotate, and the driving gear 312 engages to drive the toggle gear 313 to rotate. The toggle member 3131 on the toggle gear 313 is adapted to the driving slot 3141 and pushes the tooth ruler 314 along the slide The moving component moves, and at the same time, the tooth ruler 314 engages to drive the lock tongue gear 321 to rotate, so that the lock tongue 32 rotates, so that it withdraws from the sliding lock fastener 42, and the unlocking is completed; when the visitor uses the video intercom component 5, first, the collected audio and video signals are compressed and encoded by the audio and video processing component, and then transmitted to the platform through the communication component, and the platform is forwarded to the user's smart device. The user receives and displays the visitor's real-time video through the application on the smart device, and communicates with the visitor through the microphone of the smart device, so as to confirm the visitor and unlock the door through the wireless signal.

[0046] When fingerprint recognition and other methods cannot open the glass door lock, the user needs to use a special key to insert the lock cylinder 81 and rotate it, drive the trigger rod 82 to move upward, and finally contact and press the power switch button 83. The electrical signal emitted by the power switch button 83 is directly transmitted to the single-chip microcomputer main control unit 121, so that it directly controls the drive motor 311 to complete the quick unlocking. When the single-chip microcomputer main control unit 121 also fails to work, the electrical signal emitted by the power switch button 83 will be directly connected to the drive motor 311 along another circuit, directly driving it to unlock. It should be noted that the electrical signal directly emitted to the drive motor 311 will cause it to continuously drive the drive gear to rotate, which may cause it to be damaged faster. The key needs to be pulled out and the power needs to be cut off as soon as possible.

[0047] It should be particularly noted that the glass door lock is equipped with a three-axis sensor. Once an abnormal situation is detected, such as prying, external force damage, etc., which causes the door lock to be abnormal, it will automatically trigger an alarm prompt, thereby improving safety.

[0048] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or substitutions made to the present invention by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
