Implementation of 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 body (14), a clutch mechanism and a lock opening mechanism. The body (14) of the lock contains a front sleeve (3) and a fixed inner sleeve (1), in which a rotating sleeve (7) of the lock is located, containing the input (2) and end parts (11), and in the input 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, designed to transfer force to compress the trigger spring (5) of the pin (8) when the tail of the electronic key is inserted into the hole of the stationary inner sleeve (1), and fix the trigger spring (5) of the pin (8) by means of a locking mechanism (6).

A lock opening mechanism containing an electronic control board (15) configured to identify the electronic code of the electronic key and transmit a signal to the electromagnet (13), which is configured to transfer force to the locking mechanism through the leash (12) by transferring 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 transfer of force to the end part (11) of the rotating sleeve (7) of the lock associated with leash (12), carried out by moving the pin (8) into the hole of 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 pin (8 ), while the slider (4) and the pin (8) are made with the possibility of returning to their original position due to the accumulated energy of the return spring when the tail of the electron is removed key from the hole 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 hole of the fixed inner sleeve (1), while the protrusions of the tail part of the electronic key are located in the input part (2) of the rotating sleeve (7) of the lock, while the body of the electronic key consists of a body close in size to a typical car key with a special tail. After inserting the electronic key into the specified well, the negative and positive contacts in the tail section of the electronic key are closed with positive (16) and negative power contacts through the metal of the input part (2) of the rotating sleeve (7) of the lock for power transmission and data exchange 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 liner protrusions engage with the slider (4), as a result of which the slider (4) with the return spring moves, which in turn compresses the trigger spring (5) transmitting force to the pin (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 closing the opposite polarity contacts of the key 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 reliability of the command and, in case of a match of the code sewn in the electronic board of the key, transmits the control a pulse signal to the electromagnet (13), which acts on the locking mechanism (6) to release the pin (8) from being held. Then, using the energy of the compressed trigger spring (5), the pin moves and enters the hole in the end part (11) to transfer the force from the rotation of the sleeve (7) of the lock to the end part (11). The end part (11) of the rotating sleeve (7) of the lock is connected to a leash (12), with the help of which it transmits the force from the rotation of the electronic key to the locking mechanism. To optimize the turn-on time of the electromagnet (13), to 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 the balls (9) installed in it, which, when they fall into specially made recesses in the end part (11), are fixed its desired position relative to the rotating sleeve (7) of the lock.

Due to the grooves in the well, the fixed inner sleeve (1) of the lock and the location of the protrusions of the tail part of the electronic key in the input part (2) of the rotating sleeve (7) of the lock, the electronic key, due to the presence of the locking mechanism (6), can be pulled out only in one position of the rotating sleeve (7) of the lock, which ensures synchronization of the location of the hole in the end part (11) of the rotating sleeve (7) of the lock opposite the pin (8).

When the tail part of the electronic key is removed from the input part (2) of the rotating sleeve (7) of the lock, after turning the electronic key to a position where it can be pulled out of the hole of the fixed inner sleeve (1) of the lock, the slider (4) is moved to its original position by the return spring. position, which in turn returns the pin (8) to its original position due to the limiting pin (17) of the pin (8), which engages with the groove of the slider (4) with its protrusions, while the hook of the locking mechanism (6) under the action of the spring the electromagnet (13) enters the groove of the pin (8), which ensures that the pin (8) is fixed in its original position. Fixation of the pin (8) in the initial position ensures the return of the locking mechanism to its original state.

The reduction in 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 consumed 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 the operation of the blocking mechanism. Approximately about 140 mW for 4-10 milliseconds.

After the locking mechanism has been activated, the lock can be in the unlocked state for any length of time without consuming the energy of the electronic key battery.

The locking mechanism returns to its original position due to the accumulated energy of the return spring when the electronic key is removed from the hole of the fixed inner sleeve (1) of the lock, while the protrusions of the tail part of the electronic key come out of the input 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 lock mechanism is made in such a way that there is no direct impact of the tail of the electronic key on the lock mechanism. The locking mechanism works only from the electromechanical automatics of the trigger mechanism.

The invention has been described above with reference to a specific embodiment. For specialists, other embodiments of the invention may be obvious, without changing its essence, as it is disclosed in the present description. Accordingly, the invention is to be considered limited in scope by the following claims only.
