Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5According to an embodiment of this utility model, a smart door lock with an anti-drilling mechanism includes a door lock body 2. The door lock body 2 is equipped with a face recognition device 5 (camera) and a button 6 (which can be used to input a password) for a smart unlocking component. The door lock body 2 is also equipped with a handle 7, which is equipped with a fingerprint recognition area 8 (which can be unlocked by fingerprint). The door lock body 2 is equipped with a keyhole 12 (which can be unlocked by a key). The door lock body 2 is also equipped with a battery, lock body, lock cylinder, circuit board, communication module, etc., which can be used to unlock as needed. In order to improve the anti-theft performance, the lock cylinder can be a Class C lock cylinder to improve security. It can also be equipped with anti-drilling plates and other measures to improve the anti-drilling performance. The door body 1 (partial illustration in the figure) is provided with an installation groove 20 to facilitate the assembly of the door lock body 2. This is a relatively mature technology and will not be described in detail here.

[0025] Please see Figures 1-5To improve the drill resistance and security of the door lock body 2, a base plate 4 is welded to the bottom of the door lock body 2. A drill resistance cover 3 is installed on the door lock body 2 via a lifting mechanism. The drill resistance cover 3 and the base plate 4 can be made of hardened steel or manganese steel to increase hardness and ensure drill resistance. To ensure that unlocking is not affected, the lifting mechanism includes two sets of motors 17 installed inside the door lock body 2 (with a reserved cavity for placing the motors 17, not shown in the figure). The output ends of the motors 17 are fixedly mounted with screws via couplings. The door lock body 2 has a slot 21 that matches the screw 15. A fixing block 14 (connectable via a bearing) is rotatably mounted on the top of the screw 15. The fixing block 14 is welded to the door lock body 2. A moving block 16 is threaded onto the screw 15 and can move up and down within the slot 21. The moving block 16 is welded to the inner wall of the anti-drilling cover 3. To ensure stability and avoid affecting the up-and-down movement, guide blocks 11 are symmetrically welded onto the door lock body 2. The side wall of the anti-drilling cover 3 has a sliding mechanism for easy up-and-down movement. The guide groove 13 is combined with the anti-drill cover 3. The bottom end of the anti-drill cover 3 is welded with a positioning post 18 of the positioning component.

The voice broadcaster 22, the temperature sensor 23 and the motor 1 are also connected. 7 is also electrically connected to the PLC controller. Multiple temperature sensors 23 can be provided and distributed inside the anti-drill cover 3. When the anti-drill cover 3 is broken open, the temperature sensor 23 detects the temperature rise and transmits the signal to the PLC controller. The voice broadcaster 22 then issues an alarm. When unlocking, the motor 17 can be controlled by a preset voice (a relatively mature technology, which will not be described in detail here), which can open the anti-drill cover 3 for easy unlocking, improving security and convenience.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, when unlocking, the voice recognition sensor 10 recognizes the user's preset voice, and then the PLC controller controls the motor 17 to rotate clockwise, which in turn rotates the screw 15. This, in conjunction with the guide block 11 and the guide groove 13, moves the moving block 16 and the anti-drilling cover 3 upward, opening the anti-drilling cover 3. Then, the unlocking operation can be performed through the fingerprint recognition area 8, button 6, face recognition device 5, or keyhole 12 on the door lock body 2. After completion, the motor 17 rotates counterclockwise, which in turn rotates the screw 15. This moves the anti-drilling cover 3 downward to reset, and the positioning pin 18 is inserted into the positioning hole 9. With the help of the rubber sleeve 19, the anti-drilling cover 3 contacts the base plate 4, which can protect the door lock body 2. On the one hand, it can prevent dust and other substances from entering the interior, and on the other hand, it can improve security, prevent damage, and improve service life and safety.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
