[0003] A smart door lock with an anti-tamper alarm, disclosed in Chinese patent CN217400586U, reveals, through research of existing technology and the aforementioned patent, that criminals can illegally unlock it by forcibly dismantling it, seriously threatening the safety of customers' lives and property. Therefore, this utility model proposes a smart door lock with an anti-tamper alarm. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a smart door lock with anti-tamper alarm.

[0006] The purpose of this utility model is achieved through the following technical solution: a smart door lock with anti-tamper alarm, comprising a base plate, a main body fixedly connected to the top of the base plate, a groove formed at the center of the bottom of the main body, a vibration sensor disposed on the side of the main body away from the groove, a speaker fixedly connected to one side of the bottom of the main body, a controller fixedly connected to the bottom of the main body near the speaker, a power supply disposed on the side of the main body near the controller, a pressure sensor fixedly connected to the inside of the base plate near the groove, a padding layer adhered to the top side of the base plate near the groove, and the pressure sensor electrically connected to the controller.

[0007] Preferably, a plug is fixedly connected to the side of the base plate near the top, and a connecting wire is fixedly connected to the side of the base plate near the plug.

[0008] By adopting the above technical solution, the insertion rod is connected to the lock cylinder, and the connecting wire is connected to the door lock on the other side of the door panel.

[0009] Preferably, a face recognition camera is provided on the side of the main body near the top, a touch screen is provided on the side of the main body near the bottom of the face recognition camera, and a fingerprint recognition device is provided at the center of the main body.

[0010] Preferably, the vibration sensor is electrically connected to the controller, the vibration sensor is located inside the center of the main body, and the vibration sensor is fixedly connected to the main body by screws.

[0011] By adopting the above technical solution, after an external object collides with the main body, the vibration sensor can transmit the vibration signal to the controller, and the controller can control the speaker to issue an alarm.

[0012] Preferably, the speaker is electrically connected to the controller, the power source is a lithium battery, and the power source is located at the bottom of the main body.

[0013] By adopting the above technical solution, the power supply located at the bottom of the main body can be easily disassembled and replaced.

[0014] Preferably, the size of the pad is adapted to the size of the groove, the pad is made of soft rubber, and the depth of the groove is three centimeters.

[0015] By adopting the above technical solution, the padding layer can protect the fingers that are inserted into the groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This tamper-proof smart door lock uses a pressure sensor. The sensor is fixedly connected to the inside of the base plate near the groove, and a padding layer is adhered to the top side of the base plate near the groove. When an intruder uses a pry bar to break the lock, the pry bar presses against the padding layer as it enters the groove. The pressure sensor at the bottom of the padding layer is compressed and sends a signal to the controller. The controller then activates a speaker to sound an alarm. Similarly, if an intruder directly attacks the lock from the outside, a vibration sensor sends a signal to the controller, which in turn activates a speaker to sound an alarm, thus achieving the purpose of alarm activation.
