[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Referring to the above figures, the present invention provides a lock panel including a front panel 1 and a rear panel 2. The front panel 1 includes a first outer shell and a first base plate 3 detachably connected by multiple screws. The front of the first outer shell is provided with a fingerprint sensor 60. The rear panel 2 includes a second outer shell 4 and a second base plate 5 detachably connected by multiple screws. The first outer shell is composed of a stationary shell 6 and a movable shell 7. The movable shell 7 can slide relative to the stationary shell 6, and the movable shell 7 and the stationary shell 6 are positioned by a positioning structure. The front of the stationary shell 6 is provided with a digital touch button 8 and a keyhole 9. The front panel 1 also has an anti-pry alarm structure.

[0029] In this embodiment, the lock can be unlocked by fingerprint, password, or key, offering diverse unlocking methods to meet the unlocking needs of different scenarios. The moving housing 7 can slide relative to the stationary housing 6. Under normal circumstances, the moving housing 7 slides down to cover the front of the stationary housing 6 (digital touch button 8 and keyhole 9), allowing unlocking with only fingerprint. This also prevents dust and debris from entering the keyhole 9. When a password or key is required for unlocking, the housing 7 can be slid up. When the battery is dead, the lock can be unlocked with a key, preventing situations where unlocking is impossible due to power failure. The positioning structure can position the moving housing 7 in the position after sliding up or down, facilitating unlocking operations for the user. When the moving housing 7 slides up and does not slide down after a set time, for example, if a criminal slides the housing 7 up and pries the lock cylinder through the keyhole 9, the anti-pry alarm structure will sense it and sound an alarm, enhancing security. The anti-pry alarm structure also serves to remind the user to slide the housing 7 down to hide the digital touch button 8 and keyhole 9.

[0030] Reference Figure 2-5 As shown, the upper front of the stationary housing 6 is fixed with a sliding plate 10 by multiple screws, and the back of the moving housing 7 is fixed with a base plate 11 by multiple screws. Slide rails 12 are provided on both the left and right sides of the base plate 11. The left and right sides of the sliding plate 10 are inserted into the slide rails 12 to achieve a sliding connection. A baffle 13, bent inwards and capable of blocking the upper end of the sliding plate 10, is provided on the upper part of the base plate 11. The stationary housing 6 and the first base plate 3 are detachably connected by multiple screws. A first main plate 14 is provided inside the stationary housing 6. A first through hole 15 and a second through hole 16 are provided on the upper part of the stationary housing 6. A cover 17, which blocks the first through hole 15 and the second through hole 16, is fixed to the stationary housing 6 by multiple screws. The positioning structure includes a positioning ball 18 disposed in the first through hole 15, and the positioning ball 18 and the cover 17... A first spring 19 is provided between the covers 17. The upper and lower parts of the back of the movable housing 7 are provided with positioning grooves 20 for the positioning ball 18 to be inserted. The digital touch button 8 is connected to the first main board 14. The anti-pry alarm structure includes a first magnet 21 located in the second through hole 16. The movable housing 7 is provided with a second main board 22. The second main board 22 is connected to the first main board 14 through a ribbon cable 23. The second main board 22 is provided with a first Hall sensor 24 that can be aligned with the first magnet 21. After the movable housing 7 is opened upwards, the first Hall sensor 24 is aligned with the first magnet 21. The first Hall sensor 24 is set to activate after a delay after sensing the first magnet 21. The fingerprint sensor 60 is located on the front of the movable housing 7 and is connected to the second main board 22 through a wire.

[0031] In this embodiment, the moving housing 7 and the stationary housing 6 are slidably connected by the slider 10, the base plate 11, and the slide rail 12, resulting in a stable and robust structure. The baffle 13 provides a limiting effect on the moving housing 7, preventing it from sliding excessively upwards. The positioning structure is housed within the first through hole 15 via the cover 17. The positioning ball 18 is pushed outwards by the force of the first spring 19. When the moving housing 7 slides upwards to open or downwards to close, the positioning ball 18 is respectively pushed into the positioning groove 20 on the upper or lower part of the back of the moving housing 7, completing the positioning of the moving housing 7 and facilitating user unlocking and other operations. The lower movable housing 7 covers the digital touch buttons 8 and the keyhole 9. When a password or key is required to unlock, the upper movable housing 7 moves upward. At this time, the first Hall sensor 24 aligns with and senses the first magnet 21. The alarm time for the first Hall sensor 24 to sense the magnet is preset. For example, if the movable housing 7 is not closed after 10 seconds, an alarm will sound. This serves two purposes: firstly, it reminds the user that the movable housing 7 has not been closed; secondly, it has an anti-pry function. If criminals need to open the movable housing 7 to pry the lock cylinder, the alarm will sound if the movable housing 7 is not closed within a certain time, thus achieving the purpose of anti-pry lock and increasing security.

[0032] Reference Figure 6-9The second housing 4 contains a third main board 25, which is connected to the first main board 14 via wires. Multiple battery springs 26 are soldered to the upper left and right sides of the third main board 25, and batteries are connected between the springs 26.

The lower end of the switch knob 29 has a sleeve 30, on which a rotating plate 31 located above the third circuit board is mounted. The upper and lower ends of the rotating plate 31 are equipped with features that can align with the second Hall sensor. The device 27 or the third Hall sensor 28 has a lug 32, which has a third through hole 33. A second magnet 34 is installed in the third through hole 33. The second Hall sensor 27 is located on the upper side of the sleeve 30, and the third Hall sensor 28 is located on the right side of the sleeve 30. The transmission structure includes a housing 35 that is detachably connected to the second outer shell 4 by multiple screws. The housing 35 is detachably connected to a top cover 36 by multiple screws. The housing 35 has a first rotating shaft 37, a second rotating shaft 38, a third rotating shaft 39, and a fourth rotating shaft 40. A motor 41 is fixed to one side of the housing 35 by multiple screws. The motor 41 is connected to the third main board 25 and is powered by a battery. The rotating shaft of the motor 41 is inserted into the housing 35, and a first tooth is fitted on the rotating shaft of the motor 41. Wheel 42; a second gear 43 is fitted on the first rotating shaft 37, the lower end of the second gear 43 having a crown tooth 44 that meshes with the first gear 42; a first double-layer gear 45 is fitted on the second rotating shaft 38, the upper gear of the first double-layer gear 45 meshing with the second gear 43; a second double-layer gear 46 is fitted on the third rotating shaft 39, the upper gear of the second double-layer gear 46 meshing with the lower gear of the first double-layer gear 45; a third double-layer gear 47 is fitted on the fourth rotating shaft 40, the lower gear of the third double-layer gear 47 meshing with the lower gear of the second double-layer gear 46; a sleeve 30 passes through the housing 35 and the upper cover 36, and a third tooth that meshes with the upper gear of the third double-layer gear 47 is fitted on the sleeve 30 located inside the housing 35. The wheel 48 has a photosensitive switch 49 on the third circuit board. The housing 35 has a fourth through hole for aligning with the photosensitive switch 49. The lower end of the third double-layer gear 47 has a reflector 50 that can be aligned with the fourth through hole and the photosensitive switch 49. When the second magnet 34 at the upper end of the rotating plate 31 is aligned with the second Hall sensor 27, the reflector 50 is aligned with the photosensitive switch 49. The diameter of the third gear 48 is larger than the diameter of the lower gear of the third double-layer gear 47. The diameter of the lower gear of the third double-layer gear 47 is larger than the diameter of the upper gear of the second double-layer gear 46. The diameter of the upper gear of the second double-layer gear 46 is larger than the diameter of the upper gear of the first double-layer gear 45. The diameter of the upper gear of the first double-layer gear 45 is larger than the diameter of the crown tooth 44 of the second gear 43.

[0033] In this embodiment, the battery spring 26 is welded to the third main board 25 for easy assembly. Two lugs 32 (second magnets 34) arranged at 180°, a second Hall sensor 27 and a third Hall sensor 28 arranged at 90°, and a transmission structure enable automatic identification of left-opening and right-opening doors. Initially, the lugs 32 and second magnets 34 on the upper end of the rotating plate 31 are positioned above the second Hall sensor 27, and the reflector 50 is aligned with the photosensitive switch 49, indicating a locked state. When this invention is installed on a door for the first use of a left-opening door, the switch knob 29 rotates counterclockwise by 90°, driving the sleeve 30, rotating plate 31, and the lugs 32 (second magnets 34) to move. The lug 32 and the second magnet 34 rotate together to unlock the door. At this time, the lug 32 and the second magnet 34 on the upper end of the rotating plate 31 move away from the top of the second Hall sensor 27. Simultaneously, the lug 32 and the second magnet 34 on the lower end of the rotating plate 31 rotate to the top of the third Hall sensor 28. When the sleeve 30 rotates counterclockwise, it drives the third gear 48 to rotate counterclockwise. The third gear 48 drives the third double-layer gear 47 and the reflector 50 to rotate, causing the reflector 50 to move away from the top of the photosensitive switch 49. That is, when the third Hall sensor 28 senses the second magnet 34 at the lower end of the rotating plate 31 and the photosensitive switch 49 does not detect reflection, it is identified as a left-opening door. When first used on a door for right-opening doors, the switch knob 29 is rotated 90° clockwise, causing the sleeve 30, rotating plate 31, lug 32, and second magnet 34 to rotate together to unlock the door. At this time, the lug 32 and second magnet 34 on the upper end of the rotating plate 31 move away from the second Hall sensor 27 and rotate to the upper end of the third Hall sensor 28. When the sleeve 30 rotates counterclockwise, it drives the third gear 48 to rotate counterclockwise. The third gear 48 drives the third double-layer gear 47 and reflector 50 to rotate, causing the reflector 50 to move away from the upper end of the photosensitive switch 49. That is, the third Hall sensor 28 senses the second magnet 34 on the upper end of the rotating plate 31, and the photosensitive switch is activated. When no reflection is detected at 49, it is identified as a right-opening door. The identification of left-opening and right-opening doors can be achieved through the first operation. Since the diameter of the third gear 48 is larger than the diameter of the lower gear of the third double-layer gear 47, the diameter of the lower gear of the third double-layer gear 47 is larger than the diameter of the upper gear of the second double-layer gear 46, the diameter of the upper gear of the second double-layer gear 46 is larger than the diameter of the upper gear of the first double-layer gear 45, and the diameter of the upper gear of the first double-layer gear 45 is larger than the diameter of the crown tooth 44 of the second gear 43, the diameter of each gear gradually decreases, making the rotation of the switch knob 29 and the sleeve 30 easier. Conversely, the diameter of each gear gradually increases, which is driven by the motor 41.

[0034] See attached document Figure 1-3As shown in Figures 6-7, the first main board 14 and the third main board 25 are respectively connected to speakers 51. The static housing 6 and the second outer housing 4 are respectively provided with a plurality of fifth through holes 52 aligned with the speakers 51. The second main board 22 is connected to an unlock button 53, a lock button 54 and a doorbell button 55 that pass through the moving housing 7. The second main board 22 is provided with an NFC sensor. The moving housing 7 is provided with an NFC logo 56 aligned with the NFC sensor. The third main board 25 is connected to an unlock button 57 and a lock button 58 that pass through the second outer housing 4. The second outer housing 4 is provided with a battery cover 59 that covers the area of ​​the battery spring 26 by means of a snap fastener.

[0035] In this embodiment, if the movable housing 7 is not closed after a predetermined time, an alarm will be sounded through the speaker 51. This serves to remind the user that the movable housing 7 has not been closed, and also to alert the user inside the door, while deterring unscrupulous individuals from picking the lock. The NFC sensor allows the device to be unlocked by swiping an NFC card or using an electronic device with NFC functionality. The user inside the door can also perform related operations using the unlock button 57 and the lock button 58, providing diverse locking and unlocking options to meet the different needs of different users.
