Biometric fingerprint safe

A biometric fingerprint safe comprising a housing with a chamber, a lid hinged with the housing and upwardly liftable to expose at least a part of the chamber, a supporting mechanism provided between the housing and the lid for applying an upward force against the lid,

• wherein a bolt is fixed on the lid and the bolt has one end connected to and movable with the lid by the supporting mechanism and an opposite end matched with a latching mechanism installed in the housing;
• wherein the housing includes a fingerprint module having a fingerprint window that is exposed on the housing for collecting fingerprints, a fingerprint detecting unit electrically connected to the fingerprint window, and an MCU controller;
• wherein the latching mechanism has a motor electrically connected to the fingerprint module, a driving locking plate driven by an eccentric rod connected with the motor, and a driven locking plate which is arranged side by side and coplanar with the driving locking plate, wherein the driven locking plate is selectively drivable by the driving locking plate to rotate, so that the driven locking plate is selectively set in a first condition of engaging with the bolt for locking the lid and a second condition of disengaging from the bolt for releasing the lid;
• and
• wherein the driven locking plate comprises a sheet-shaped body, a first protrusion extending from the sheet-shaped body of the driven locking plate in a direction toward the driving locking plate, and a second protrusion formed on the sheet-shaped body of the driven locking plate;
• and the driving locking plate comprises a sheet-shaped body coplanar with the sheet-shaped body of the driven locking plate, a third protrusion extending from the sheet-shaped body of the driving locking plate in a direction toward the driven locking plate, and a fourth protrusion formed on the sheet-shaped body of the driving locking plate and adjacent to the third protrusion, wherein a first recess is defined between the third protrusion and the fourth protrusion and the first protrusion of the driven locking plate is received in the first recess and co-planarly located between the third protrusion and the fourth protrusion of the driving locking plate, and the eccentric rod, such that the driven locking plate is set in the second condition, the first protrusion of the driven locking plate being selectively drivable by the third protrusion of the driving locking plate to rotate in a first direction for setting the driven locking plate in the second condition and drivable by the fourth protrusion of the driving locking plate to rotate in a second direction opposite to the first direction for setting the driven locking plate in the first condition.
