A screw rod 12 is provided at the output end of the motor 13, and the screw rod 12 is threadedly connected to the center hole of the pin shaft 11. The upper end of the pin shaft 11 is inserted into the pin hole below the lock core 4. A fingerprint verification 2 is also provided on one side below the lock body 1, and the fingerprint verification 2 is electrically connected to the control circuit 14, and the control circuit 14 is electrically connected to the motor 13.

[0024] The passive key 3 is provided with a plurality of electrical contacts 301 , and the electrical contacts 301 are electrically connected to the control circuit 14 via an electrical connection device inside the lock core 4 .

[0025] A pressing seat 7 is also provided on one side of the lock body 1 . The pressing seat 7 covers the lock body 1 . A first screw 8 passes through the pressing seat 7 and is threadedly connected to the lock body 1 .

[0026] The passive key 3 is inserted into the lock core 4, and the fingerprint data and current inside the passive key 3 are transmitted to the control circuit 14. The hand of the person who unlocks the door presses the fingerprint verification 2 position. The fingerprint verification 2 is powered on and the fingerprint data is verified. After the fingerprint data matches the fingerprint number inside the passive key 3, the motor 13 drives the pin shaft 11 to drop from the inside of the lock core 4. The passive key 3 can rotate the lock core 4 to unlock the door. The lock body 1 is designed with an embedded installation method. After the lock body 1 is installed, the clamping seat 7 on the back is used to fix the lock body 1. The installation structure is simple and practical.

[0027] The body 1 is a main frame, and adopts a cavity structure design, which accommodates various key components inside, and at the same time maintains a sealed isolation from the external environment to enhance dust and water resistance. A lock core protection cover 5 is provided at its upper end to protect the internal lock core 4 from external environmental interference and malicious damage.

[0028] The lock core 4 is a core mechanical component, which is rotatably connected to the lock core protective cover 5, and one end of which is connected to the lock bolt 6 through a transmission mechanism to achieve the locking and unlocking functions. The lock core 4 is integrated with a power connection device, which is used to contact the power connection contact 301 of the passive key 3 to transmit current and fingerprint data.

[0029] The pin shaft 11 is arranged inside the lock body 1, and its lower end is threadedly connected with the screw 12 at the output end of the motor 13 to form an electric drive mechanism. The upper end of the pin shaft 11 is inserted into the pin hole below the lock core 4, and the lifting and lowering of the pin shaft 11 is controlled by the rotation of the motor 13, thereby affecting the rotational freedom of the lock core 4.

[0030] The fingerprint verification 2 is located at one side below the lock body 1 and is responsible for collecting and verifying the user's fingerprint information. It is electrically connected to the control circuit 14 to realize the processing and comparison of fingerprint data.

[0031] The control circuit 14, as the "brain" of the smart lock, receives and processes the current and fingerprint data from the passive key 3, as well as the verification result of the fingerprint verification 2. According to the preset logic, the control circuit 14 issues instructions to control the motor 13 to move, thereby determining whether the lock is opened or not.

[0032] The passive key 3 carries the user's fingerprint data and contacts the power connection device inside the lock body through the power connection contact 301 when inserted into the lock cylinder 4, and transmits current and fingerprint data to the control circuit 14. The lock can only be opened when the fingerprint data in the key matches the user's fingerprint collected through fingerprint verification 2.

[0033] The installation and fixing method is as follows: the clamping seat 7 is installed on one side of the lock body 1 and is threadedly connected to the lock body 1 through the first screw 8 to form a stable support and protection for the lock body. The design of the clamping seat simplifies the installation process of the lock, so that the lock body can be easily fixed on the cabinet door or other carrier in an embedded manner without complicated modification or customization.

[0034] In the preferred embodiment, the outer wall of the lock core 4 is provided with a plurality of conductive rings 401, the inner wall of the lock core protective cover 5 is provided with a plurality of annular grooves matching the conductive rings 401, the conductive rings 401 are arranged inside the annular grooves, and the conductive rings 401 are electrically connected to the control circuit 14 through wires.

[0035] In the preferred embodiment, the structure of the power connection device is as follows: a plurality of blind holes are provided on both sides of the keyhole of the lock core 4, a shock column 402 is provided inside the blind hole, a spring 404 is provided between the bottom of the shock column 402 and the bottom of the blind hole, and a power connection post 403 is also provided at the bottom of the blind hole, the power connection post 403 is connected to the shock column 402 through a wire, and the power connection post 403 rests on the conductive ring 401. The end of the shock column 402 rests on the power connection contact 301 of the passive key 3, and the power connection post 403 is connected to the shock column 402 through a wire, and outputs the current and data of the passive key 3 to the control circuit 14.

[0036] When the passive key 3 is inserted into the lock cylinder 4, its electrical contact 301 will accurately contact the conductive ring 401 to form an electrical connection. In this way, the current and fingerprint data stored in the passive key can be transmitted to the inside of the lock cylinder protective cover 5 through the conductive ring 401. To ensure that these electrical signals can be further transmitted to the control circuit 14, each conductive ring 401 is directly electrically connected to the control circuit through a wire. This design ensures the reliable transmission of current and data between the key, lock cylinder, lock cylinder protective cover and control circuit, and provides the necessary hardware support for the smooth dual authentication of fingerprints and passive keys.
