The control front plate 6 and the control rear plate 3 are connected by wires. The transmission rod 4 is sleeved on the outside of the wire.

[0037] In this embodiment, the mounting shell 1 is a single metal or plastic panel without additional functions, and can also be attached with separate or integrated motor clutch transmission structure, battery box and other accessories. In this way, the size and shape of the mounting shell 1 can be adjusted accordingly according to the parameters of the door and the lock body, such as a vertical rectangular appearance of 75*360mm or a circular appearance of 65mm in diameter, etc., so as to improve the adaptability of the smart lock to different usage scenarios.

[0038] When the utility model is in use, if biometric information is used, such as fingerprint unlocking, the fingerprint side of the finger is attached to the surface of the fingerprint receiving sensor 62, and the fingerprint receiving sensor 62 will transmit the biometric signal in the form of an electrical signal to the PCB front plate 63 for identification. The PCB front plate 63 will compare the electrical signal with the stored electrical signal. After the comparison is completed, the PCB front plate 63 releases the state in which the flip rod 5 cannot be flipped. After unlocking, the housing 7 is held and rotated downward. At this time, the flip rod 5 will be driven to rotate, and the flip rod 5 rotates the transmission rod 4 to rotate, and the transmission rod 4 drives the card block in the lock core to move. After the card block moves, the connection between the door and the door frame is released, and the door can be opened. The design of the control back plate 3 is to serve as a relay for input power, control the input power to the PCB front plate 63, and prevent the entire lock from being burned out by excessive current.

[0039] In a specific embodiment, Figure 3 The control front panel 6 includes an interface 61, a fingerprint receiving sensor 62, a PCB front panel 63, a speaker 64, a clutch socket 65, a front connecting wire holder 66 and a three-color lamp 67. The PCB front panel 63 is installed in the placement space, one end of the fingerprint receiving sensor 62 is installed at the front end of the PCB front panel 63, and the other end of the fingerprint receiving sensor 62 passes through the surface of the placement shell 7. The three-color lamp 67 is installed behind the PCB front panel 63. A small hole is opened in the PCB front panel 63, the interface 61 is installed behind the PCB front panel 63, the interface 61 is set on the right side of the three-color lamp 67, and a speaker 64 is set on the left side of the three-color lamp 67. The speaker 64 is installed behind the PCB front panel 63, the clutch socket 65 is installed behind the PCB front panel 63, the clutch socket 65 is set above the speaker 64, and a front connecting wire holder 66 is set below the speaker 64, and the front connecting wire holder 66 is installed behind the PCB front panel 63. Interface 61 is a type-c interface that can be used for external devices, speaker 64 can be used to remind the user when unlocking, clutch socket 65 is used to release the limitation of flip rod 5, and after driving clutch socket 65, flip rod 5 can rotate normally. The three-color light 67 has the same effect as speaker 64, and also reminds whether to unlock. The small hole is designed to allow the three-color light 67 to transmit light.

[0040] In a specific embodiment, a Bluetooth unit, a password unit, an IC identification unit and a fingerprint identification unit are provided on the PCB front plate 63. The Bluetooth unit can be connected to the mobile phone Bluetooth, and the mobile phone is used to control the door lock to open, making unlocking more convenient. The input of the password is through detecting the user's pressing operation on the fingerprint receiving sensor 62; according to the number of times corresponding to the pressing operation, the first password is obtained by parsing, and three sets of passwords are obtained by analogy. After the three sets of passwords are input, the password sequence stored in the PCB front plate 63 is compared to realize the unlocking operation. This password function can reduce the physical touch buttons, and retaining the password function can also save 3 / 5 of the area of ​​the PCB front plate 63. The card reading coil on the IC identification unit senses and reads the IC card, and compares it with the reserved IC card information on the PCB front plate 63 for identification.
