[0037] like Figure 1-8As shown, an embodiment of this utility model provides a lock cylinder cover structure, which can be applied to smart door locks. The lock cylinder cover structure includes an upper cover 1, a circuit board 2, a waterproof ring 3, and a bottom cover 4. The upper cover 1 forms a receiving cavity 5 and is provided with a mounting hole 6 that connects to the receiving cavity 5. A thin film 7 is attached to the upper surface of the upper cover 1, and the thin film 7 seals the mounting hole 6. The circuit board 2 is installed in the receiving cavity 5 and is equipped with a conductive ribbon cable 8. A trigger module 9 is integrated on the circuit board 2. The trigger module 9 extends into the mounting hole 6 and abuts against the thin film 7. The trigger module 9 can be triggered by touching the thin film 7. The waterproof ring 3 is tightly fitted to the lower end of the upper cover 1. A through groove 10 is provided on the bottom cover 4, and the conductive ribbon cable 8 passes through the through groove 10. The bottom cover 4 is fastened to the lower end of the upper cover 1 and seals the receiving cavity 5. When the trigger module 9 is the doorbell module 24, the lock cylinder cover also functions as a doorbell; when the trigger module 9 is the fingerprint module, the lock cylinder cover also functions as a fingerprint unlocking module, thus increasing the functionality of the lock cylinder cover and making it more than just a cover. At the same time, the lock cylinder cover structure is sealed and waterproofed by a waterproof ring 3 to prevent moisture from entering the lock cylinder and damaging the lock body.

[0038] Specifically, in this embodiment, reference is made to... Figure 1-4 The upper cover 1 is a shell structure, and its lower end forms a receiving cavity 5, which is mainly used to house the circuit board 2. A mounting hole 6 is provided on the bottom surface of the receiving cavity 5, connecting to the cavity and used to mount the trigger module 9 on the circuit board 2. The film 7 is preferably a PET film. The upper cover 1 and the film 7 can be directly integrally molded using in-mold injection molding. The film 7 is attached to the upper surface of the upper cover 1 and seals the mounting hole 6, preventing moisture from entering the receiving cavity 5 through the mounting hole 6, and also making the product more aesthetically pleasing. The circuit board 2 is installed inside the receiving cavity 5. The trigger module 9 integrated in the circuit board 2 extends towards the mounting hole 6 and contacts the film 7. The trigger module 9 can be triggered by touching or pressing the film 7. The trigger module 9 can add functionality to the lock cylinder cover. For example, when the trigger module 9 is a doorbell module 24, triggering the trigger module 9 will ring the smart lock, thus integrating the doorbell function into the lock cylinder cover, making the lock cylinder cover no longer simply a cover.

[0039] Furthermore, in this embodiment, reference is made to... Figure 1 and Figure 3 The circuit board 2 integrates an LED light 11, and the thin film 7 is provided with a light-transmitting ring 12. When the lock cylinder cover structure is installed in the lock cylinder hole 14, when the thin film 7 is touched to trigger the trigger module 9, a light ring is formed on the light-transmitting ring 12, which can serve as a reminder to the user that the door lock is working, and can also improve the quality of the door lock.

[0040] Furthermore, in this embodiment, reference is made to... Figure 1 and Figure 5 The waterproof ring 3 is a circular structure made of silicone material, which effectively improves its service life and waterproof performance. The waterproof ring 3 is tightly fitted onto the lower end of the upper cover 1. The lower end of the waterproof ring 3 forms a guide cone surface 13. When the lock cylinder cover structure is installed into the lock cylinder hole 14, the guide cone surface 13 guides the lock cylinder cover into the lock cylinder hole 14. The waterproof ring 3 is press-fitted with the inner wall of the lock cylinder hole 14, forming a waterproof seal and effectively preventing moisture from entering the lock body through the lock cylinder hole 14. In this embodiment, the circuit board 2 is equipped with a flexible conductive cable 8 for conductive connection, which is connected to the control circuit board 2 of the smart lock. The bottom cover 4 is a cover structure, securely installed at the lower end of the upper cover 1 and sealing the receiving cavity 5. The bottom cover 4 and the upper cover 1 also clamp the waterproof ring 3 together. A through groove 10 is provided on the bottom cover 4 for the conductive cable 8 to pass through. Specifically, when the smart lock requires a mechanical key to unlock, the conductive cable 8 can also hold the lock cylinder cover in place, preventing it from detaching from the lock.

[0041] Furthermore, in this embodiment, the lock cylinder cover structure also includes a waterproof pad 15. The waterproof pad 15 is disposed on the bottom surface of the circuit board 2, and the bottom cover 4 and the top cover 1 clamp the edge of the waterproof pad 15, thus sealing the receiving cavity 5. Specifically, the waterproof pad 15 is waterproof foam, which can be adhesively attached to the back of the circuit board 2. Several clearance grooves are provided on the waterproof foam to allow screws or conductive cables 8 to pass through. The waterproof foam has good waterproof performance and low cost. Its installation in the receiving cavity 5 not only provides a certain barrier against moisture but also protects the circuit board 2 from damage by the bottom cover 4.

[0042] Further, in this embodiment, the upper cover 1 is provided with mounting posts 16, the bottom cover 4 is provided with mounting holes 17, and the circuit board 2 is provided with through holes 18. The circuit board 2 is fitted onto the mounting posts 16 through the through holes 18, and screws pass through the mounting holes 17 to securely connect with the mounting posts 16. The bottom cover 4 is provided with threaded holes 19, and the circuit board 2 is secured to the threaded holes 19 by screws, pressing the waterproof gasket 15. Specifically, three mounting posts 16 extend downward from the bottom of the receiving cavity 5. The end face of the mounting posts 16 can be provided with threaded blind holes. The bottom cover 4 is provided with three corresponding mounting holes 17, and the circuit board 2 is also provided with three corresponding through holes 18. The mounting posts 16 pass through the through holes 18, the circuit board 2 is fitted onto the mounting posts 16, and screws pass through the bottom surface of the bottom cover 4 to securely connect with the mounting posts 16, thereby encapsulating the circuit board 2 in the receiving cavity 5. The bottom cover 4 is provided with two threaded through holes for securing the circuit board 2 with screws, and the circuit board 2 presses the waterproof gasket 15. During installation, waterproof foam is first attached to the back of circuit board 2. Then, circuit board 2 is secured to the top of the bottom cover 4 using screws and threaded holes 19, with mounting holes 17 aligned with through holes 18. Next, circuit board 2 is inserted into mounting post 16, with the end face of mounting post 16 aligned with mounting holes 17. Finally, screws are passed through mounting holes 17 and secured to mounting post 16. The lock cylinder cover structure is easy and quick to install, and has low production costs.

[0043] Furthermore, in this embodiment, a stepped groove 20 is provided on the end face of the receiving cavity 5, and a boss 21 is formed on one side of the bottom cover 4. The boss 21 is embedded in the stepped groove 20 for closed installation. Specifically, in order to reduce the thickness of the lock cylinder cover and make the lock cylinder cover smaller, a stepped groove 20 is provided on the end face of the receiving cavity 5, and a boss 21 is formed on the upper side of the bottom cover 4. The outer diameter of the boss 21 is adapted to the inner diameter of the stepped groove 20 so that the boss 21 can be embedded in the stepped groove 20 for installation, thereby enabling the bottom cover 4 to enclose the receiving cavity 5.

[0044] Furthermore, in this embodiment, the outer surface of the receiving cavity 5 is uniformly provided with a plurality of grooves 22, and the inner surface of the waterproof ring 3 is uniformly provided with a plurality of protrusions 23, which are embedded in the grooves 22 for stable installation. Specifically, in order to stably assemble the waterproof ring 3, the inner surface of the waterproof ring 3 is uniformly provided with a plurality of protrusions 23, while the outer surface of the receiving cavity 5 is correspondingly provided with a plurality of grooves 22. When the waterproof ring 3 is installed, the protrusions 23 can be embedded in the grooves 22 for installation, making the installation of the waterproof ring 3 more stable and preventing rotation, thus ensuring the sealing effect of the waterproof ring 3.

[0045] Furthermore, in this embodiment, the trigger module 9 is a doorbell module 24, which integrates a tactile button 25. A button body 26 is installed in the mounting hole 6, and the button body 26 abuts against the tactile button 25. The button body 26 is a silicone button, and a trigger portion 27 is formed on the inner side of the button body 26, which abuts against the tactile button 25. For details, please refer to... Figure 1-6 The trigger module 9 is configured as a doorbell module 24. The doorbell module 24 integrates a tactile button 25, which is mounted facing the mounting hole 6. A button body 26 is disposed within the mounting hole 6. The inner side of the button body 26 forms a trigger portion 27, which abuts against the tactile button 25. The upper surface of the button body 26 contacts the diaphragm 7. Touching or pressing the diaphragm 7 triggers the doorbell module 24, causing it to ring. Preferably, the button body 26 is made of silicone material, which provides elasticity, allowing the diaphragm 7 to bounce back and return to its original position after being pressed.

[0046] Furthermore, in some embodiments, the trigger module 9 is a fingerprint module (not shown), which integrates a fingerprint sensor. Contact with the thin film 7 triggers the fingerprint sensor. Specifically, the fingerprint sensor extends into the mounting hole 6 and is installed therein. Contact with the thin film 7 triggers the fingerprint sensor, which collects a fingerprint to unlock the device. Compared to the doorbell module 24, only the button body 26 needs to be replaced with a fingerprint sensor.

[0047] Furthermore, in some embodiments, the trigger module 9 is a communication module (not shown), which integrates a microphone. Contact with the diaphragm 7 triggers the microphone. Specifically, the microphone, also called a microphone head, extends into the mounting hole 6 for installation. The microphone contacts the diaphragm 7; touching or pressing the diaphragm 7 triggers the microphone, enabling intercom communication. Compared to the doorbell module 24, only the button body 26 needs to be replaced with a microphone.

[0048] In addition, embodiments of this utility model also provide a smart door lock that utilizes the aforementioned lock cylinder cover structure, see reference. Figure 7 and Figure 8The smart door lock includes a door lock assembly 28 and a lock cylinder cover assembly 29. The lock cylinder cover assembly 29 is installed in the lock cylinder hole 14 of the door lock assembly 28. The lock cylinder cover assembly 29 includes an upper cover 1, a circuit board 2, a waterproof ring 3, and a bottom cover 4. The upper cover 1 forms a receiving cavity 5 and has a mounting hole 6 that connects to the receiving cavity 5. A thin film 7 is attached to the upper surface of the upper cover 1, and the thin film 7 seals the mounting hole 6. The circuit board 2 is installed in the receiving cavity 5 and is equipped with a conductive cable 8. A trigger module 9 is integrated on the circuit board 2. The trigger module 9 extends into the mounting hole 6 and abuts against the thin film 7. The trigger module 9 can be triggered by touching the thin film 7. The waterproof ring 3 is tightly fitted to the lower end of the upper cover 1, and the waterproof ring 3 is interference-fitted with the inner wall of the lock cylinder hole 14 to form a tight waterproof seal. The bottom cover 4 has a through groove 10, through which the conductive cable 8 passes and is electrically connected to the door lock assembly 28. The bottom cover 4 is fastened to the lower end of the upper cover 1 and seals the receiving cavity 5. The trigger module 9 can be configured as a doorbell module 24, a fingerprint module, or a communication module, etc., as needed. When the trigger module 9 is a doorbell module 24, the lock cylinder cover also has a doorbell function; when the trigger module 9 is a fingerprint module, the lock cylinder cover also has a fingerprint unlocking function, thus increasing the functionality of the lock cylinder cover and making it more than just a cover. At the same time, the lock cylinder cover structure is sealed and waterproofed by a waterproof ring 3 to prevent moisture from entering the lock cylinder and damaging the lock body.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
