This type of combination lock usually has a single-tongue structure, that is, there is only one moving lock tongue, which is used to lock or unlock the door lock. Single-tongue lock combination locks are usually used in homes, offices, commercial places, etc., providing a convenient and safe access control method.

[0003] Traditional single-tongue lock body password locks only have one fingerprint (or Bluetooth) to unlock. The single unlocking method limits the functional expansion of the door lock. For example, it is impossible to realize a combination of multiple unlocking methods, such as fingerprint + password or fingerprint + Bluetooth, and it is also impossible to connect to other smart home systems to realize more functions. The functionality is not strong, and the fingerprint recognition sensor of the password lock in the prior art is directly exposed to the outside, which may be easy to damage, security risks, privacy leakage and affect the appearance.

The split fingerprint lock that integrates the four unlocking methods of fingerprint, password, card swiping and Bluetooth can provide a more diversified, safe and convenient access control method, meet the different needs of users and improve the use experience, and the split structure, once a component has a problem, it can be replaced in time, prolonging the service life of the overall system and reducing the environmental pressure caused by waste;

[0024] A pressure hole 51 is provided through the center of the surface of the password keyboard 5, and a limit rod 52 is fixedly connected inside the password keyboard 5. The outer surface of the limit rod 52 is slidably connected with a first slide plate 53 and a second slide plate 54. The opposite surfaces of the first slide plate 53 and the second slide plate 54 are fixedly connected with a sealing plate, and the first slide plate 53 and the second slide plate 54 are sealed and connected through the sealing plate. A limit block 55 is fixedly connected inside the password keyboard 5, a protrusion 56 is fixedly connected on the surface of the first slide plate 53, and a first tooth plate 57 is fixedly connected on the side of the first slide plate 53. A gear 58 is rotatably connected inside the password keyboard 5, and a second tooth plate 59 is fixedly connected on the side of the second slide plate 54. The surface of the gear 58 is meshedly connected to the surfaces of the first tooth plate 57 and the second tooth plate 59. The outer surfaces of the first tooth plate 57 and the second tooth plate 59 are both slidably connected inside the password keyboard 5, and a first spring 510 is fixedly connected to the surface of the first slide plate 53 away from the second slide plate 54. A sealing cavity 511 is provided inside the password keyboard 5, and a sealing block 512 is slidably connected to the inside of the sealing cavity 511. The surface of 512 is fixedly connected with a rope 514, and one end of the rope 514 away from the sealing block 512 is fixedly connected to the surface of the first tooth plate 57. A second spring 513 is movably installed inside the sealing cavity 511. The surface of the password keyboard 5 is provided with an air outlet groove 515 connected to the inside of the sealing cavity 511. The sealing cavity 511 is connected to the outside of the password keyboard 5 through the air outlet groove 515. A one-way valve 516 is fixedly installed inside the air outlet groove 515. The output end of the one-way valve 516 is away from the inside of the sealing cavity 511. The password keyboard 5 is provided with an air inlet groove 517, the diameter of which is smaller than that of the air outlet groove 515, and the inner bottom end of the sealed cavity 511 is connected with the outside of the password keypad 5 through the air inlet groove 517. By arranging the first slide plate 53 and the second slide plate 54 which can slide automatically, the fingerprint sensor 7 can be protected when the fingerprint unlocking is not used, and the fingerprint recognition module can be effectively protected from the influence of the external environment, such as dust, water vapor, etc., which helps to ensure the accuracy and reliability of fingerprint recognition and improve the security of the access control system.

[0025] When the fingerprint sensor 7 is used to unlock, the first slide plate 53 is driven by the protrusion 56 to slide in a direction away from the second slide plate 54. Through the meshing of the first tooth plate 57, the second tooth plate 59 and the gear 58, the first slide plate 53 and the second slide plate 54 slide in opposite directions. Through the elasticity of the second spring 513, the sealing block 512 slides inside the sealing cavity 511, and the rope 514 is pulled into the sealing cavity 511. The air inside the sealing cavity 511 is discharged from the air outlet groove 515 through the one-way valve 516. When the fingerprint sensor 7 is fully exposed, the finger can be pressed on the surface of the fingerprint sensor 7 to unlock. After the unlocking is completed, since the external air can only slowly enter the sealing cavity 511 through the air inlet groove 517, the first slide plate 53 and the second slide plate 54 slowly slide and close the pressure hole 51 through the elasticity of the first spring 510, so that the fingerprint sensor 7 can be protected, and the fingerprint recognition module can be effectively protected from the influence of the external environment, such as dust, water vapor, etc., which helps to ensure the accuracy and reliability of fingerprint recognition and improve the security of the access control system.
