Description

Electronic Door Lock

The present invention relates to an electronic door lock, and in more detail, by installing a shutter device that operates up and down or left and right at the entrance of a hole into which a key is inserted into a key cylinder, it is not possible to fundamentally prevent sidelocking, It relates to a door lock.

With the development of electronic technology, electronic door locks have been developed to perform the opening and locking of doors. Such electronic door locks are driven by the rotation of electronic door locks and key cylinders that drive lock devices with electric motors operated by pure electronic control. It is divided into an electronic door lock that combines the mechanical mechanism of the lock device.

The pure electronic door lock has a door lock that opens and locks by entering a pre-registered password using the number buttons 0-9, and stores the password or unique ID in an electronic key with non-volatile memory Various types of door locks have been developed and installed, such as door locks that open and lock by applying to lock devices, and door locks that are remotely controlled using an RF transmitter with a built-in password or unique ID.

However, when using the numeric buttons, there is a problem that the password is exposed to a third party, and there is a problem that it is not only inconvenient to use the password frequently, but also relatively weak in security. In addition, there is a problem that causes a malfunction depending on the surrounding environment has recently been developed and used electronic door lock having a mechanical mechanism configuration.

The present invention relates to an electronic door lock having a mechanical mechanism configuration. The electronic door lock as described above generally includes an electronic control part and a mechanical device part. The mechanical device part is a lock operated by rotation of a key cylinder and a key cylinder. Consists of a device.

More specifically, as shown in FIG. 1, an electronic control unit 3 including a number button is installed at an upper portion, a key cylinder 4 is installed at a lower side thereof, and an outdoor handle 5 is installed outside. An outer body 2; A locking device 6 installed inside the door 11; The door lock main body 1 is provided with an inner motor 10 installed with an electric motor which is operated by an electrical signal of the electronic controller 3 and operates the stopper 8 of the handle shaft 7 and an indoor handle 9 is installed outside. ) Consists of.

Here, the description of the key cylinder (3) is not limited to the key cylinder (3) installed in the electronic door lock, and also applies to the key cylinder (3) of the pure mechanical mechanical door lock, and also because the key cylinder is a general configuration Detailed drawings are omitted.

The key cylinder 4 is composed of an inner cylinder and an outer cylinder, and a plurality of key pins are installed therebetween, and the outer cylinder is fixed to be integrally formed with the door or the outer body, and the inner cylinder is integrally inserted with the outer cylinder by the key pin. As the key pins are aligned, the inner cylinder is rotated so that the lock device 6 can be operated.

Here, the key pin consists of a lower key pin located in the inner cylinder and an upper key pin located in the outer cylinder. The upper key pin is spring-tipped so that a portion of the upper key pin is located in the inner cylinder, thereby making the inner cylinder fixed.

That is, when the key is inserted into the key cylinder 4 for operating the lock device 6 of the door lock body 1, a plurality of key pins installed between the inner cylinder and the outer cylinder have a constant height (the height coinciding with the surface where the inner cylinder and the outer cylinder contact). The inner cylinder is rotated so as to operate the lock device 6 so that the door 11 can be opened or closed.

However, the key cylinder 4 installed in the conventional electronic door lock (including the mechanical door lock) has the problem that the locking device 6 operates only by understanding the basic structure of the key cylinder 4 and aligning the installed key pins. There was this.

In more detail, the inner cylinder of the key cylinder 4 rotates in a constant direction when a moderate force (for example, a clockwise direction) is applied to the inner cylinder of the key cylinder 4 by applying a "b" shaped clasp to the hand. You will be empowered to do so.

At this time, if you push the key pins one by one while pushing the other pusher bent with the other hand, the moment the key pin is momentarily coincided with the boundary line between the outer and inner cylinders, the inner cylinder rotates finely. The hand holding the shackle can be felt by the senses, and by using these hand senses to align the other key pins, the inner cylinder for operating the lock device 6 is rotated.

These hand feelings vary slightly from person to person, but the inner cylinder is moved to the extent that most people can feel, thus understanding the basic structure of the key cylinder (4), and anyone using the "a" shaped clasp and pusher The problem that the inner cylinder of the key cylinder 4 can be rotated is raised.

Recently, in order to improve such a problem, a key cylinder is installed and used in two or three directions instead of being installed only in one direction, but this also has a "b" shaped clasp and an electric clasp (a small part of the electric driver). The key pins were simply aligned by a power tool installed by attaching an chuck to the chuck and attaching an eccentric plate to the shaft so as to vibrate from side to side or up and down. As a result, the locking device did not function properly.

In particular, such a power clasp is a tool that can be easily obtained by anyone at a general key point or a tool store (electric tool handling shop), and thus theft crime using such a tool is increasing.

The present invention is designed to improve the problems of the electronic door lock with the conventional lock device as described above, by installing a shutter device that operates up and down or left and right at the inlet of the hole in which the key is inserted into the key cylinder, which can be used as a source of stabbing. It is an object of the present invention to provide an electronic door lock with improved security.

In order to achieve the above object, the present invention provides an outer body having an electronic control unit including an inner cylinder and an outer cylinder and an alarm device, a lock device installed in the interior of the door or installed in the inner body, and a rotating shaft of the handle. In an electronic door lock comprising an inner body having a stopper device for controlling and a power supply (battery), the key cylinder forms a supporting surface at a cylindrical outer diameter, and is provided by a fixing plate having a through hole having the same shape as the outer diameter of the key cylinder. The cylinder is integrally formed with the outer body, and a shutter device is installed on the outer body for installing the key cylinder, and the shutter device is composed of a spring-tight upper and lower shutters and a settled portion, wherein the upper and lower shutters are on one side. The spring settled groove is formed, and the other end portion forms an inclined surface, and one end of the lower shutter is extended to press the pressing portion. By forming an opening in one side with the guide groove in the settled part, even if you try to shackle by the upper and lower shutters, you can not feel the minute sense transmitted to the side by the restoring force of the spring which is hard on the upper and lower shutters. Security can be secured.
