Description

Technical Field

[0001] The utility model relates to the technical field of fingerprint password locks, in particular to a flip cover driving mechanism of a fingerprint password lock. Background Art

[0002] With the continuous acceleration of my country's urbanization process, users have put forward higher requirements for commonly used door locks. Whether it is a home door lock or a door lock in a public place, it is required to have beautiful appearance, high security, and easy use. New door locks with password instruction technology or fingerprint recognition technology are the most popular and have huge market potential in the current lock industry. Locks using fingerprint collection and recognition technology have developed rapidly in the home furnishing industry in recent years. At present, some high-end home security doors have applied fingerprint locks, which brings higher security and convenience to people's daily life and use.

[0003] Application No. CN202222719719.3 discloses a flip cover structure of an intelligent fingerprint password lock. When the fingerprint collection screen is needed, the electric telescopic rod is extended by controlling the control button, and the electric telescopic rod drives the gear rod to extend. The gear rod engages with the gear and then drives the rotating shaft to rotate. The rotating shaft drives one end of the storage rod to rotate, and the other end of the storage rod drives the storage rod to adaptively change the angle, thereby driving the flip plate to flip outward around the bottom hinge, so that the fingerprint collection screen appears, that is, the fingerprint can be collected. When it needs to be stored after use, the electric telescopic rod is shortened by controlling the control button, and the electric telescopic rod drives the gear rod to move back. During the movement, it engages with the gear to drive the rotating shaft to rotate in the opposite direction, which can drive the flip plate to rotate in the opposite direction, so that the flip plate drives the fingerprint collection screen to flip into the hidden groove, thereby improving the visual aesthetics and preventing dust from falling on the fingerprint collection screen and causing errors in fingerprint collection.

[0004] The combination lock controls the extension of the electric telescopic rod through a control button, and the electric telescopic rod drives the gear rod to extend, and the gear rod meshes with the gear to drive the rotating shaft to rotate, and the rotating shaft drives one end of the storage rod one to rotate, and the other end of the storage rod one drives the storage rod two to adaptively change its angle, thereby driving the flip plate to flip outward around the bottom hinge, so that the fingerprint collection screen appears to collect fingerprints. Although the password button and the fingerprint collection device are protected, the flip cover needs to share a battery energy with the fingerprint, resulting in a larger power demand of the combination lock. Therefore, a flip cover drive mechanism of the fingerprint combination lock is required. Utility Model Content
