Abstract
This utility model discloses a smart padlock, relating to the field of padlock technology. It includes a front shell and a rear shell. A silicone button is placed inside a hole in the front shell, and the edge of the silicone button is pressed firmly onto the front shell by a pressure plate. A USB plug and a keyhole plug are installed at the bottom of the front shell. A dome switch is located on the side of the pressure plate away from the silicone button, and the dome switch is attached to the button PCB. The button PCB is fixed to the pressure plate with screws. The main board is located inside the front shell and fixed with screws. A raised plate is provided on one side of the main board, and a semiconductor fingerprint module is soldered to one side of the raised plate. This utility model proposes a large padlock that simultaneously possesses fingerprint and physical button unlocking functions, giving users more usage options and making it more user-friendly. Because the silicone button, USB plug, and keyhole plug are all waterproof, it is suitable for damp and rainy environments, so users don't have to worry about the lock breaking and being unable to open the door in the rain. The internal structure of the lock has anti-knock characteristics, thus greatly improving user security.
