Carrying out the invention

Electromechanical locking device contains an electronic key and a lock. The electronic key contains a tail section with protrusions, negative and positive contacts, and a housing in which a power source and an electronic board for storing the electronic code are located.

The lock contains a housing (14), a clutch mechanism and a lock opening mechanism. The lock body (14) contains a front bushing (3) and a fixed inner bushing (1), in which a rotating lock bushing (7) is located, containing an inlet (2) and an end part (11), and in the inlet part (2) there are negative and positive (16) contacts of the lock, and the end part (11) is connected to the locking mechanism of the lock through a leash (12).

The clutch mechanism contains a slider (4) with a return spring, configured to transmit force to compress the trigger spring (5) of the finger (8) when inserting the tail part of the electronic key into the well of the fixed inner sleeve (1), and fixing the trigger spring (5) of the finger (8) using the locking mechanism (6).

A lock opening mechanism containing an electronic control board (15) configured to identify the electronic code of an electronic key and transmit a signal to an electromagnet (13), which is configured to transmit force to the locking mechanism through the driver (12) by transmitting force to the end part (11) of the rotating sleeve (7) of the lock when turning the electronic key in the input part (2) of the rotating sleeve (7) of the lock after identifying the electronic code of the electronic key, and the force is transmitted to the end part (11) of the rotating sleeve (7) of the lock associated with leash (12), carried out by moving the finger (8) into the hole in the end part (11) of the rotating sleeve (7) of the lock after the action of the electromagnet (13) on the locking mechanism (6), leading to the release of the trigger spring (5) of the finger (8 ), while the slider (4) and pin (8) are designed to return to their original position due to the accumulated energy of the return spring when removing the tail part of the electronic key from the well of the fixed inner sleeve (1).

The claimed electromechanical locking device operates as follows.

The tail part of the electronic key is inserted into the well of the stationary inner sleeve (1), while the protrusions of the tail part of the electronic key are located in the inlet part (2) of the rotating sleeve (7) of the lock, while the body of the electronic key consists of a body with dimensions close to a typical car key with a special tail part. After inserting the electronic key into the specified well, the negative and positive contacts in the tail part of the electronic key are closed with the positive (16) and negative power contacts through the metal of the input part (2) of the rotating sleeve (7) of the lock for transmitting power and exchanging data between the electronic control board (15) and an electronic key board containing an electronic code.

When the electronic key is inserted into the specified well, the protrusions of the shank engage with the slider (4), resulting in the movement of the slider (4) with a return spring, which, in turn, compresses the release spring (5), transmitting force to the finger (8 ). The trigger spring (5) of the pin (8) is held by the locking mechanism (6), thereby cocking the locking mechanism (6) from the force of inserting the electronic key.

After the opposite-polarity contacts of the key are closed with the opposite-polarity contacts of the lock, the electronic key supplies electrical energy to the electronic board (15) of the lock control to open the lock, the electronic board (15) of the lock control determines the validity of the command and, in case of a match,

Claims (1)

The code written into the electronic board of the key transmits a control pulse signal to the electromagnet (13), which acts on the locking mechanism (6) to release the finger (8). Then, using the energy of the compressed trigger spring (5), the finger moves and enters the hole in the end part (11) to transmit the force from the rotation of the lock sleeve (7) to the end part (11). The end part (11) of the rotating sleeve (7) of the lock is connected to a driver (12), with the help of which it transmits the force from the rotation of the electronic key to the locking mechanism. To optimize the activation time of the electromagnet (13) and control the operation of the locking mechanism (6), position sensors of the locking mechanism (6) can be installed. Synchronization of the location of the end part (11) and the rotating sleeve (7) of the lock opposite the pin (8) is carried out due to the operation of the separator (10) with balls (9) installed in it, which, when they fall into specially made recesses in the end part (11), fix it in the desired position relative to the rotating sleeve (7) of the lock. Due to the grooves in the well, the stationary inner sleeve (1) of the lock and the location of the protrusions of the tail part of the electronic key in the inlet part (2) of the rotating sleeve (7) of the lock, the electronic key, due to the presence of a locking mechanism (6), can be pulled out only in one rotating position bushing (7) of the lock, which ensures synchronization of the location of the hole in the end part (11) of the rotating bushing (7) of the lock opposite the pin (8). When removing the tail part of the electronic key from the input part (2) of the rotating sleeve (7) of the lock, after turning the electronic key to a position in which it can be pulled out from the well of the fixed inner sleeve (1) of the lock, the slider (4) is moved by the return spring to its original position position, which, in turn, returns the finger (8) to its original position due to the limiting pin (17) of the finger (8), which with its protrusions engages with the groove of the slider (4), while the hook of the locking mechanism (6) is under by the action of the electromagnet spring (13) it enters the groove of the pin (8), which ensures the fixation of the pin (8) in its original position. Fixing the pin (8) in its original position ensures that the locking mechanism returns to its original state. Reducing energy costs when opening and closing the lock is achieved due to the fact that the energy from the power source (battery) of the electronic key is spent to transfer force from a miniature low-power electromagnet controlled by an electronic board only to the locking mechanism to decompress the trigger spring. Little energy is spent on operating the locking mechanism. Approximately about 140 mW for 4-10 milliseconds. After the locking mechanism has been activated, the lock can remain in the unlocked state for any length of time without consuming energy from the electronic key battery. The locking mechanism returns to its original position due to the accumulated energy of the return spring when removing the electronic key from the well of the stationary inner sleeve (1) of the lock, while the protrusions of the tail part of the electronic key come out of the inlet part (2) of the rotating sleeve (7) of the lock. Battery power is not consumed to return the locking mechanism to its original position. The lever locking mechanism is made in such a way that there is no direct impact of the tail part of the electronic key on the locking mechanism. The locking mechanism is activated only by the electromechanical automatic trigger mechanism. The invention has been described above with reference to a specific embodiment thereof. Other embodiments of the invention may be obvious to those skilled in the art but do not change its essence as disclosed in the present description. Accordingly, the invention should be considered limited in scope only by the following claims.
