Description

An electronic lock cylinder device

Technical field

The invention relates to a lock, in particular to an electronic lock core device.

Background technique

At present, with the development of social life and technology, smart home-related hardware has mushroomed.

Come. Since there is no need to carry a key, electronic locks are easy to use and solve the pain points of many people in daily life, so they have gained popularity.

Rapidly spread. At present, most electronic locks are produced and sold in the form of complete locks, which are not only costly but also inconsistent with existing locks.

The shapes and sizes are quite different and the installation is difficult. Just the need for professionals to install it greatly increases the threshold for using electronic locks. Compared with electronic locks in the form of complete locks, electronic lock cylinders have low cost and are installed similarly to mechanical lock cylinders, so they have gained widespread attention.

However, the internal mechanical structure of the electronic lock cylinder is very tight, and the internal space is difficult to accommodate both the mechanical and electronic unlocking structural components. Therefore, existing products are basically single-function electronic lock cylinders, in which the mechanical unlocking function is omitted, and the electronic lock cylinder part is mainly driven by electronics.

Chinese patent application CN201510760277.9 discloses a method for realizing an electronic lock cylinder. The electronic lock cylinder disclosed in this application includes a front handle and a rear handle. The front handle includes a fingerprint and password authentication system, and the rear handle includes related authentication electronic circuits. The interiors of the front handle and the rear handle are integrated and can rotate freely together. The rear handle shell and the dial are integrated, and the rotation of the rear handle will cause the dial to rotate to open and lock the door. Without correct identity authentication, the inner parts of the front handle and rear handle are free to idle and cannot drive the dial to rotate, so the door cannot be opened or locked. The clutch is housed in the rear handlebar. When there is correct identity authentication (for example, by fingerprint or password), the interior of the rear handle is connected to the outer shell of the rear handle through the movement of the clutch in the rear handle. At this time, rotating the front handle drives the internal rotation of the rear handle, and the internal rotation of the rear handle drives the rear handle shell to rotate, thereby driving the dial to rotate, thereby achieving the purpose of opening or locking the door.

Chinese patent application CN201520877874.5 discloses an electronic lock cylinder. There is a handle on the outside of the electronic lock cylinder (relative to the outside where the door is installed). The handle is equipped with fingerprint recognition, Bluetooth and other related electronic components, and a clutch is installed. When the user passes the fingerprint identification, the clutch inside the handle is driven to combine with the lock cylinder body, and then the lock tongue can be opened by turning the outer handle to drive the dial wheel inside the lock cylinder. This electronic lock core cannot be opened mechanically with a key and is a single-function electronic lock.

The electronic lock cylinder device of claim 1, wherein: the driving assembly comprises an output shaft which rotates with the motor and a clutch block which can reciprocate on the output shaft, a torsion spring sleeved on the output shaft is arranged in the clutch block, the torsion spring is fixedly arranged in the clutch block, a driving pin is arranged on the output shaft, and the driving pin is positioned in the clutch block and is movably arranged along the distance of the torsion spring when the output shaft rotates so as to drive the clutch block to axially move relative to the output shaft.

4. The electronic lock cylinder device of claim 1, wherein: a first compression spring is arranged between the clutch assembly and the front main shaft and used for driving the clutch assembly to return.

5. The electronic lock cylinder device according to claim 1 or 4, characterized in that: the clutch assembly comprises a movable sleeve and a bolt body, wherein the movable sleeve is partially sleeved on the bolt body, and a second compression spring is arranged between the movable sleeve and the bolt body.

6. The electronic lock cylinder device of claim 5, wherein: the through holes are formed in pairs on two sides of the front main shaft, clutch parts are respectively arranged in the two through holes, a cone structure with the cross section gradually reduced in the moving direction of the backward handle assembly is arranged on the plug pin body, and the cone structure drives the clutch parts to move along the through holes to the notch when the plug pin body moves in the backward handle assembly direction.

7. The electronic lock cylinder device of claim 1, wherein: the clutch part is a ball with the size matched with the section of the through hole.
