[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: an intelligent door lock structure that can prevent violent dismantling, including an installation shell 1, a control component 2 and a lock body 3.

[0024] A control component 2 and a lock body 3 are installed inside the installation shell 1, a lock tongue body 301 is arranged on one side of the lock body 3, a keyboard 201 and a camera 202 are installed on one side of the installation shell 1, handles 101 are symmetrically installed on both sides of the installation shell 1, a knob 102 is installed on one side of the installation shell 1, a self-locking mechanism 4 is arranged inside the installation shell 1, and the self-locking mechanism 4 consists of a vibration sensor 401, a mounting slot 402, a bidirectional drive motor 403, an adjusting screw 404, a plug-in column 405, a plug-in slot 406, an abutment block 406a and a reset spring 406b, and a vibration sensor 401 is installed at the bottom of the installation shell 1.

[0025] A mounting groove 402 is provided on one side of the lock body 3, and a bidirectional drive motor 403 is installed inside the mounting groove 402. Adjustment screws 404 are connected to both ends of the bidirectional drive motor 403 through couplings. The outer side of the adjustment screw 404 is threadedly connected to the threaded hole inside the plug-in column 405. A plug-in groove 406 is provided on one side of the two lock tongue bodies 301 close to the bidirectional drive motor 403. The plug-in groove 406 is elastically connected to the abutment block 406a through a return spring 406b.

[0026] In the specific implementation, in order to prevent the bolt body 301 from loosening and rebounding due to strong vibration, when the installation shell 1 is subjected to continuous violent impact, the vibration sensor 401 inside the installation shell 1 will sense the vibration signal and transmit the vibration signal to the control component 2 for processing. At this time, the control component 2 will control the start of the two-way drive motor 403, and the two-way drive motor 403 drives the adjustment screw 404 to rotate through the couplings at both ends, and the threaded action of the threaded hole inside the plug-in column 405 pushes the plug-in column 405 to both sides until the plug-in column 405 is plugged into the plug-in slot 406 on the adjacent side. At this time, the smart door lock can self-lock the bolt body 301 to prevent the bolt body 301 from loosening and rebounding;

[0027] The plug-in slot 406 inside the lock tongue body 301 is equipped with an abutment block 406a through a reset spring 406b. When the plug-in slot 406 is not plugged into the plug-in column 405, the reset spring 406b will drive the abutment block 406a to move and block the plug-in slot 406, so as to prevent impurities from entering the plug-in slot 406 and affecting the use. At the same time, it can assist in pushing the plug-in column 405 to reset. The intelligent door lock structure that can prevent violent dismantling is provided with a self-locking mechanism 4, which can self-lock the lock tongue body 301 of the door lock, effectively preventing the internal components of the lock body 3 from being damaged and causing the lock tongue body 301 to automatically rebound, thereby improving the safety of the door lock.

[0028] See also Figure 4 and Figure 5 It can be seen that a protective mechanism 5 is provided on one side of the installation shell 1, and the protective mechanism 5 is composed of a plug-in frame 501, an installation frame 502, an elastic membrane 502c, a protective layer 502d, a sealing sleeve 502e, a limit groove 502f, a limit block 503, a push block 504, a connecting spring 505 and a mounting frame 506. The plug-in frame 501 is connected to the side of the installation shell 1 close to the keyboard 201, and the plug-in frame 501 is plugged with the installation frame 502 inside, and the installation frame 502 is installed with an elastic membrane 502c inside. A protective layer 502d and a sealing sleeve 502e are installed on the upper side of the installation frame 502, and the protective layer 502d is made of transparent plastic. A limiting groove 502f is provided on the upper side of the installation frame 502, and the inner side of the limiting groove 502f is plugged into the limiting block 503. Push blocks 504 are symmetrically installed on both sides of the limiting block 503. A connecting spring 505 is installed inside the limiting block 503. The inside of the limiting block 503 is plugged into the installation frame 506, and the bottom of the installation frame 506 is connected to the plug-in frame 501.

[0029] During specific implementation, the keyboard 201 will be worn to varying degrees due to long-term use and friction, which will shorten the service life of the keyboard 201. After the door lock is installed, the limit block 503 is pushed to both sides by the push block 504, and the installation frame 502 is plugged in from the bottom of the plug-in frame 501 until the installation frame 502 and the plug-in frame 501 are abutted and stopped, and the push block 504 is released. At this time, the limit block 503 moves relatively under the action of the internal connection spring 505 and the installation frame 506 until it is plugged and limited with the limit groove 502f at the bottom of the protective layer 502d. The user can press the keyboard 201 through the elastic membrane 502c to enter the password, which effectively reduces the wear of the keyboard 201.

[0030] At the same time, a sealing sleeve 502e with good sealing effect is provided at the joint between the upper side of the installation frame 502 and the slot of the plug-in frame 501, which has a good waterproof effect while preventing the keyboard 201 from being worn. The installation frame 502 is easy to install and can be removed in time for cleaning and repeated use. The protective layer 502d on the upper side of the installation frame 502 is used to protect the camera 202 to prevent the camera 202 lens from being worn. The intelligent door lock structure that can prevent violent dismantling is provided with a protective mechanism 5, which can effectively protect the keyboard 201 and extend the service life of the keyboard 201.

[0031] To sum up, when using the intelligent door lock structure that prevents violent dismantling, after the user enters a specific password through the keyboard 201, the control component 2 installed inside the shell 1 controls the decoding. After the decoding is completed, the control component 2 sends an instruction to the control circuit inside the lock body 3. The control circuit inside the lock body 3 controls the corresponding components to retract the lock tongue body 301. The user can open the door by pulling the handle 101. The camera 202 on the upper side of the shell 1 is used to assist the user to observe the environment outside the door, and the knob 102 is used to assist in locking the door.
