Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] The embodiment of the present invention discloses an intelligent door lock. The inventor has found through research on the structure of the American fingerprint recognition double tongue door lock in the prior art that although the existing American fingerprint recognition double tongue door lock can carry out fingerprint recognition and realize Functions such as opening and locking the door, but its structure is relatively complicated. After fingerprint veri...

Abstract

An embodiment of the invention discloses a door lock. When fingerprints of a user are verified by a fingerprint verifying system 12, a control circuit in the fingerprint verifying system 12 sends out electric signals to a single motor 10 in the door lock so as to push a slide rail piece 11 and control positions of a pin 9 of a gear device to realize gear shift, and a handle 3 can be mechanically pressed to rotate in place, so that a locking spring bolt 1 can retract into the door lock, and the door lock is unlocked, and further, the door lock can be locked when the handle 3 is lifted outside a door. The door lock can be unlocked mechanically under driving of the single motor, so that electric energy is saved, the structure of the door lock is simpler as compared with a fingerprint verification double-bolt American door lock in the prior art, and probability of failure is decreased by the aid of the single motor. Besides, the door lock utilizes the model integrating gear parts in the prior art with a door opening shaft, brings great convenience for quick switching of leftwards opening and rightwards opening, and accordingly, is simple and convenient in operation and humanized in design.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to an American-style door lock with a fingerprint recognition function. Background technique [0002] A door lock is a device that locks the door to prevent others from opening the door. It is a barrier for people's homes and offices to prevent theft and only allow specific people to enter. Due to the needs of safety, convenience and stability, people have higher and higher requirements for door locks. American door locks are popular with people for their smooth appearance and relatively high safety performance. [0003] Among the existing American door locks, there is a type that can be used for fingerprint recognition, which can realize fingerprint opening and key opening with the same lock. There are two motors in this type of door lock to control the opening of the locking bolt and the oblique bolt respectively. The expansion and contraction of the tongue depends entirely o...
