Description

The field of technology to which the useful model belongs

The present invention relates to an electronic lock and, in particular, to an electronic lock having an electronic circuit that interacts with the antenna of the cylinder lock to set the lock in the open or closed position by actuating the locking pin of the actuator.

Prerequisites of the invention

Standard locks use pins of different lengths to prevent the lock from being opened without the appropriate key. Deadbolts are most commonly used in cylinder locks, but can also be found in tubular locks with a deadbolt mechanism. Also, instead of a key, there is a plastic card with a magnetic stripe on the back. When the card is swiped inside the lock, the electronic circuit of the reader decodes the information on the strip and checks the correspondence with the code stored inside it. If the key matches, the circuit activates a strong electromagnet that pulls the bolt aside, allowing the door to open.

Conventional mechanical locks can be at risk from keystrokes, but the locks and associated deadbolts are inherently mechanical and cannot be changed. There are several types of electronic locks on the market that have a complex mechanism that will always be expensive. The key of electronic locks is very important because it can be easily damaged by water or wet environment. In addition, the power supply battery of the key can be damaged or discharged, in which case finding a new power supply battery to replace it may not be easy.

Many electronic locks have complex parts, which makes them expensive compared to standard locks. The key of electronic locks mainly contains a power supply battery, which can be difficult to replace if necessary. It is also desirable that such a system is fully electronic, i.e. independent of a mechanical barb or key when opening the lock cylinder.

Document 056442985 (B1) discloses a lock with an electromagnetic locking device that can be locked or unlocked with an electronic key or a mechanical key. The electromagnetic locking device is located in the upper part of the housing and functions as an executive mechanism of the cylinder lock for the key to be inserted into

From the engagement of the locking rod with the groove of the lock, provided in the clutch, or the release from the engagement from it, with locking or unlocking of the rotation of the clutch, respectively.

Document 052003084691 (AT) discloses the section of the lock, which is mechanically operated by a key provided with identification information to perform a locking or unlocking operation. The receiving device receives identification information from the key.

The verification device determines whether the identification information received by the receiving device matches the previously stored registration information of the key.

The limiter restricts the key unlock operation when the verification device determines that the identification information does not match the registration information.

In document UR 562 173354A, the lock is opened to prevent any malicious unlocking due to the selection of keys. The lock includes a lighting element on the handle in order to emit an optical signal from it directed to an optical receiving device, a power battery installed inside or on the handle to actuate the lighting element; and switching means for providing start/stop control of electrical actuation of the lighting element in accordance with the angular position of the rotary part thereof.

Document 052002189307 (A1) discloses door locks with numerical electronic or electromechanical keys suitable for one or a group of locks. The lock cylinders in the document may or may not contain deadbolts or other mechanical combination to match the mechanical lock. When the access criteria are met, the locking device of the electrically operated lock unlocks, allowing the key to be turned. The cylinder lock disclosed in the document uses an electrically actuated locking device, usually a small electromagnet or actuator that is released or pivoted to allow the key to be turned.

Objectives of the invention

The main purpose of this invention is to provide an electronic lock made with the possibility of electronic transmission of information from the key to the cylinder for setting the lock in the open or closed position.

Another object of the present invention is to provide an electronic lock having an antenna on the first half of the cylinder, so that said lock can be used with a socket that allows the use of locks in steel doors.

Another object of the present invention is to provide an electronic key lock that does not contain a power supply battery to ensure a long service life.

Another object of the present invention is to provide an electronic lock that is suitable for any type of door, even steel doors.

It is also an object of this invention to provide an electronic lock that is resistant to attempts to unlock with a key.

The essence of the invention

The present invention provides an electronic lock comprising: a cylinder body having a first cylinder half and a second cylinder half; the core, which has a groove for inserting the key, made with the possibility of turning inside the specified cylinder body; an executive mechanism with electromagnetic control inside the cylinder body having a locking pin, while the executive mechanism with electromagnetic control drives the indicated locking pin downward or upward according to the longitudinal axis of the electronic lock; an antenna that receives data from an electronic circuit; and an electronic card that compares the data read from the antenna with the data stored in its memory to determine the acceptability of the data received from the antenna, the electronic card providing an activation signal to the electromagnetically controlled actuator to move the locking pin. Said antenna is located on the axis of the key, so that a radio frequency signal or an optical band frequency signal can be used in the event of the exclusion of the use of a battery power supply in it, when the key is fully inserted into the slot, thus the indicated locking pin selectively engages with the core to prevent its rotation and disengages from the core in response to an activation signal to permit its rotation.

With reference to the figures described above, a preferred embodiment of the present invention comprises a cylinder body (1) having a first cylinder half (14a) and a second cylinder half (145), a handle (7) located on the second cylinder half with a rod (b) for the handle, the actuator (2) for activating the locking pin (3) for locking the core (8) of the cylinder body, the antenna (4) for receiving the signal coming from the electronic circuit (9) of the key (11), electronic card (12).

With reference to fig. 1, said electronic lock (15) comprises a cylinder body (1) into one end of which a key (11) can be inserted to activate the stopper (10), and the other end of the cylinder body is equipped with a handle (7) for locking or unlocking the door by the user

According to fig. 2, which shows the section A-A in fig. 1, the actuator (2) is placed on the first half (14a) of the cylinder with the locking pin (3), when the user inserts the key (11) inside the cylinder body (1), the antenna (4) detects the electronic circuit (9) of the key (11) , which is placed on the tip of the key, and the actuator (2) drives the locking pin (3) up or down according to the longitudinal axis (X) of the electronic lock. The indicated first half of the cylinder (14a) has a catch socket (20) in the form of a trough, engages with the locking pin (3) when the actuator is activated.

The specified electronic circuit (9) of the key (11) interacts with the antenna (4), which is interconnected with the electronic card (12) using connecting cables (5). Verification and identification of the data received from the antenna (4) is processed on the electronic card (12), if the electronic card (12) confirms the insertion of a certain key (11) into the cylinder housing (1), then a signal is received on the actuator (2). The user can define more than one key (11) for the electronic lock (15) with the electronic card (12). The electronic card (12) compares the data read from the antenna (4) with the data stored in its memory to determine the acceptability of the data received from the antenna (4), while the electronic card (12) issues an activation signal to the executive mechanism (2) with electromagnetic control for moving the locking pin (3).

The main idea of this invention is the electromechanical interaction between the key and the lock cylinder. The electronic locking system according to the present invention provides a locking system that is characterized by effective and universal characteristics, i.e.

With access control functions. In fig. 4a shows a perspective view of the electronic lock (15), when the end part (16) of the key (11) is fully inserted into the groove.

The specified locking pin (3) can preferably be monolithic and prevents movement of the cylinder body (1). When the pin (3) is in the extended position, as seen in fig. 3, the actuator releases the pin (3) and allows rotation of the core (8). Before inserting the key (11) into the groove, the locking pin (3) is held in a vertical position, as shown in fig.

Q. After the electronic part of the key makes the decision to "allow access" after fully inserting the authorized key (fig. b), the actuator is activated by pulling out the locking pin (3).

In a second embodiment of the invention, the antenna (4) can be selectively connected to a detector configured to respond to a radio frequency signal, or to a detector configured to respond to an optical frequency signal, and interacts with the electronic card (12). The executive mechanism (2) accommodates a locking pin (3) with electromagnetic control, which is located perpendicular to the longitudinal axis of the electronic lock. The locking pin (3) adjoins a groove-shaped area that prevents rotation of the core (8) in certain positions of the executive mechanism. When the electronic lock (15) recognizes that the corresponding key is inserted, the actuator (2) is actuated, the locking pin (3) retracts into the grooved seat of the actuator (2). Thus, the core (8) is unlocked and can turn. After removing the key from the groove, the locking pin (3) returns to its fully lowered position and blocks the core (8).

A spring (22) can be used and, in turn, can push the locking pin (3) into the locked position.

The corresponding design of the key 11, shown in fig. 5, quite similar to the design of a conventional mechanical key. The axis of the key (11) and especially the end part (16) of the key (11) accommodates an electronic circuit (9) which is suitable for interaction with the antenna (4). The specified place for placing the electronic circuit has a cross-section in the shape of a rectangle. Due to its characteristics, the indicated key does not contain a power supply battery for the electronic circuit (9), thus it provides a long service life and durability. Due to the fact that the electronic circuit (9) of the key is located on the tip of the key axis, there is no need to use strong electronic materials. Advantageously, there is no need for a battery 60 to power the key, especially for the electronic circuit, and a long service life is also achieved. In an alternative embodiment of the invention, said antenna (4) can be selectively connected to a detector configured to respond to a radio frequency signal or to a detector configured to respond to an optical frequency signal and interacts with an electronic card (12) so that the use of a battery the power supply in the key is turned off.

After inserting the appropriate key, the antenna detects the electronic circuit and sends a signal to the electronic card. The data is processed by an electronic card to actuate the actuator (2) with electromagnetic control, withdrawing the locking pin and allowing free rotation of the core (8). Thus, the actuator is actuated only when the locking pin has been moved down to its open position, which activates the actuator.

In the second embodiment of the invention, when the locking pin (3) is in its locking position, in order to return the pin, it is necessary to provide a current through the coil to create a field with a polarity that is opposite to the polarity of the electromagnetic means, with a sufficient current strength. When a current of the opposite polarity is applied, the locking pin (3) will move down. As long as the key is not present, the locking pin remains in the locked position.

In fig. 6 shows a sectional view of the executive mechanism of the electronic lock according to the present invention. The specified executive mechanism (2) mainly contains an electromagnet (24) having coil windings (23) and a spring (22) that presses the locking pin (3). When the electronic card (12) actuates the windings (23) of the coil, the coil is also actuated with the stop pin extending, so the core can move.
