[0025] Combination Figures 1 to 7 As shown, an intelligent security door includes a door frame 1, a door body 2, and a lock cylinder 3.

[0026] A limiting hole 11 is provided on one inner side of the door frame 1; the door body 2 is rotatably connected to the door frame 1, and an installation cavity 21 is provided on the door body 2; the lock cylinder 3 is located in the installation cavity 21 and extends through the door body 2 into the limiting hole 11; the lock cylinder 3 includes: a locking assembly 31, an intelligent control panel 32, and an inner panel 33. The intelligent control panel 32 is located on one side of the locking assembly 31, outside the door body 2, and is electrically connected to the locking assembly 31. The intelligent control panel 32 is used to automatically drive the locking assembly 31 to be slidably embedded in the limiting hole 11; the inner panel 33 is located on the other side of the locking assembly 31, inside the door body 2, and is drively connected to the locking assembly 31. The inner panel 33 is used to manually drive the locking assembly 31 to be slidably embedded in the limiting hole 11.

[0027] The design incorporates a lock cylinder 3 within the mounting cavity 21 of the door body 2, extending into the limiting hole 11 of the door frame 1. This lock cylinder 3 ensures a more stable and reliable connection between the door body 2 and the door frame 1, effectively preventing displacement or loosening of the door body 2 due to external forces. Furthermore, a locking assembly 31 is fixedly installed within the mounting cavity 21 of the door body 2, and an intelligent control panel 32 is positioned on one side of the locking assembly 31 outside the door body 2. This intelligent control panel 32 is electrically connected to the locking assembly 31, allowing users to automate the process. This design not only simplifies the locking and unlocking process but also supports remote control and timed locking / unlocking. The intelligent control panel 32, along with other intelligent functions, greatly enhances the convenience and flexibility of use. It can automatically drive the locking component 31 to slide and embed itself in the limiting hole 11, providing an efficient security protection mechanism. Compared with the traditional mechanical lock cylinder, this design adds an electronic protection layer, further enhancing the security factor of the anti-theft door and effectively preventing illegal intrusion. By setting an inner panel 33 on the other side of the locking component 31 inside the door body 2, the inner panel 33 is connected to the locking component 31 under the action of the inner panel 33. The user can manually operate the inner panel 33 to drive the locking component 31 to slide and embed itself in the limiting hole 11, so as to facilitate the opening of the anti-theft door from the inside.

[0028] To further explain, the intelligent control panel 32 is equipped with a fingerprint area, a control panel area, and a control chip inside.

[0029] The fingerprint area is a key component of modern smart locks. It verifies user identity by reading the user's fingerprint and comparing it to a pre-stored fingerprint template. This not only enhances security but also greatly simplifies daily use, as users no longer need to carry keys or remember passwords.

[0030] Control Panel Area: This area typically includes a numeric keypad or touchscreen for entering passwords or executing other commands. For example, it can be used to set temporary access passwords or view recent unlocking records. The control panel provides users with an intuitive interface, making it easier to manage and configure smart locks.

[0031] Internal control chip: This is the core component of the smart lock, responsible for processing all electronic signals and data. The control chip manages functions such as fingerprint recognition, password verification, and communication with external devices (such as smartphone applications). It is also the foundation for realizing advanced functions such as remote control and timed locking. Furthermore, the control chip needs to have a certain level of protection to prevent unauthorized cracking or tampering.

[0032] Combination Figure 2 As shown, the intelligent control panel 32 has a groove 321. The groove 321 can serve as a physical auxiliary design to facilitate the user to push and close the door 2, thereby separating the door frame 1 and the door 2 and placing the door 2 in an open or closed state.

[0033] Combination Figure 4 As shown, the control chip is electrically connected to the locking assembly 31, which includes: a mounting plate 311, a limit bar 313, a rack 314, a drive motor 315, a first gear 316, a linkage assembly 317, and an electric push rod 318. A sliding groove 312 is horizontally formed in the mounting plate 311; a limiting strip 313 is slidably disposed in the sliding groove 312, and one end of the limiting strip 313 is slidably embedded in the limiting hole 11; a rack 314 is disposed on the upper and lower sides of the limiting strip 313; a drive motor 315 is disposed above the limiting strip 313, and the drive motor 315 is electrically connected to the control chip in the intelligent control panel 32; a first gear 316 is sleeved on the output end of the drive motor 315, and the first gear 316 and the rack 314 are meshed through a linkage component 317, which is rotatably disposed in the sliding groove 312; an electric push rod 318 is disposed above the linkage component 317, and the electric push rod 318 is electrically connected to the control chip in the intelligent control panel 32. The linkage component 317 includes: a rotating plate 3171, a second gear 3172, and a third gear 3173. The rotating plate 3171 is rotatably disposed in the slide groove 312, and a second gear 3172 and a third gear 3173 are respectively rotatably disposed on both sides of the rotating plate 3171, with the second gear 3172 and the third gear 3173 meshing with each other; the output end of the electric push rod 318 is in contact with the rotating plate 3171.

[0034] Initially, the rotating plate 3171 is horizontal. The user inputs the correct fingerprint or password via the smart control panel 32 or sends a command via a mobile application. Upon receiving the signal, the control chip simultaneously activates the drive motor 315 and the electric push rod 318. This continues until the electric push rod 318 contacts the rotating plate 3171, causing the rotating plate 3171 to rotate relative to the mounting plate 311. The rotating plate 3171 then drives the second gear 3172 and the third gear 3173 to rotate at a certain angle until the second gear 3172 engages with the drive motor... The first gear 316 on 315 meshes with the third gear 3173 and the rack 314 on the limiting strip 313. Only in this way can the drive motor 315 drive the first gear 316 to rotate, and the first gear 316 sequentially drives the first gear 316 and the third gear 3173 to rotate, thereby indirectly driving the rack 314. The rack 314 pushes the limiting strip 313 to slide backward along the slide groove 312, so that it exits from the limiting hole 11, completing the unlocking action. And with the help of the pull groove 321, a gap is created between the door frame 1 and the door body 2, thus completing the open state of the door body 2.

[0035] Combination Figure 5 As shown, a limit plate 3174 is provided on one side of the rotating plate 3171, and a first spring 3175 is provided between the limit plate 3174 and the rotating plate 3171 to ensure that the rotating plate 3171 can be reset to the initial state when no external force is applied, thus ensuring the stability and reliability of the entire system.

[0036] To further explain, the limiting strip 313, embedded in the limiting hole 11, has an arc-shaped chamfer 3131 at one end. During insertion, the arc-shaped chamfer disperses the pressure at the contact point, preventing sharp edges from scratching or wearing the inner wall of the limiting hole. This not only extends the service life of the limiting strip and the limiting hole but also ensures long-term stability.

[0037] Combination Figure 4 As shown, a second spring 319 is provided between the other end of the limiting strip 313 and one side wall of the slide groove 312. The second spring 319 is in a compressed or stretched state in its natural state. When the drive motor 315 and the electric push rod 318 stop working, the elastic force of the spring will drive the limiting strip 313 to slide in the opposite direction along the slide groove 312 until one end of the limiting strip is re-embedded into the limiting hole 11.

[0038] Combination Figure 3 As shown, an inner door handle 331 is rotatably mounted on the inner panel 33. A rotating shaft 332 is mounted on the inner door handle 331. One end of the rotating shaft 332 passes through the mounting plate 311 and extends to the slide groove 312, where a fourth gear 333 is fitted. The fourth gear 333 meshes with the rack 314.

[0039] When the user rotates the inner door handle 331, the rotating shaft 332 rotates accordingly, driving the fourth gear 333 to rotate. Since the fourth gear 333 meshes with the rack 314, the rotation of the gear will push the rack 314 to move along the slide groove 312, causing the limit bar 313 to disengage from the limit hole 11, thus completing the unlocking action.

[0040] The working principle of this utility model is as follows: External fingerprint unlocking: The user places their finger in the fingerprint area of ​​the smart control panel 32 for fingerprint recognition. The smart control panel 32 reads the user's fingerprint information and compares it with a pre-stored fingerprint template. If the fingerprint matches successfully, the control chip in the smart control panel 32 receives an unlock signal. The control chip then activates the drive motor 315 and the electric push rod 318. The electric push rod 318 pushes the rotating plate 3171, causing it to rotate relative to the mounting plate 311. The rotating plate 3171 drives the second gear 3172 and the third gear 3173 to rotate together, until the second gear 317... 2 meshes with the first gear 316, and the third gear 3173 meshes with the rack 314. The drive motor 315 drives the first gear 316 to rotate, which in turn drives the second gear 3172 and the third gear 3173 to rotate, thereby indirectly driving the rack 314. The rack 314 pushes the limiting strip 313 to slide backward along the slide groove 312, so that it exits from the limiting hole 11, completing the unlocking action. After unlocking, the user can push open the door 2 with the pull groove 321 on the intelligent control panel 32, so that a gap is created between the door 2 and the door frame 1, realizing the open state of the door 2.

[0041] Unlock via internal handle: The user stands inside the door, grasps the inner door handle 331, and prepares to rotate it. The user rotates the inner door handle 331, causing the rotating shaft 332 to rotate accordingly. One end of the rotating shaft 332 passes through the mounting plate 311 and extends into the slide groove 312, where a fourth gear 333 is fitted. The fourth gear 333 rotates with the rotation of the rotating shaft 332 and meshes with the rack 314. The rotation of the gear pushes the rack 314 to move along the slide groove 312. The rack 314 pushes the limiting strip 313 to slide backward along the slide groove 312, causing it to exit from the limiting hole 11, thus completing the unlocking action. After unlocking, the user can push or pull the door 2 through the inner door handle 331 to create a gap between the door 2 and the door frame 1, thus opening the door 2.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
