The electronic padlock 1 (Fig. 1, 2, 7) is installed on the object using the eyes 2. The electronic padlock 1 (Fig. 3, 4) contains the power unit 3 and the locking means 4. The power unit 3 is designed for mechanical coupling of the power elements lock in the housing 5. The locking tool 4 is designed to install the elements of the power node in the position: locked or unlocked by the forces applied to it by the user. The power node 3 consists of two parts 6, 7 of the housing 5, the “U” -shaped handle 8. The handle 8 has locking means 4: two slide parts 9, two ends 10 of the handle 8 are chamfered 11. Case 5 (Fig. 1, 3 , 4) and the handle 8 is made of antimagnetic solid brass grade LS-59-1. The housing 5 (Fig. 6a, 6b, 6c) is equipped with a device for simultaneously locking the lock and two parts 6, 7 of the housing. To connect with each other, the first 6 and second 7 parts of the housing 5 are equipped with four pins 12 (Fig. 6a, 6b, 6c, 5) and four sockets 13, while in the assembled form the pins 12 of the first part 6 (Fig. 6a, 6b, 6c ) the housing is located in the sockets 13 of the second part of the housing 7, and the pins 12 of the second part of the housing 7 are located in the sockets 13 of the first part of the housing 6, each pin 12 in turn is provided with an opening 14 (Fig. 6a, 6b, 6c, 5), the diameter of which corresponds to the diameter of the slider part 9 (Fig. 6a, 6b, 6c) of the “U” -shaped arm 8, while the axis 15 of the hole 14 pins 12 of the two parts 6, 7 of the housing They are on the same axis with the axes 16 of the sliders of the “U” -shaped handle 8, in the assembled position, the slider part 9 of the handle 8 is located in the holes 14 of the pins 12 of the first 6, and the second 7 of the housing blocking the first 6 and second 7 of the housing, the lock of the lock 1 and the lock of the two parts 6, 7 of the case occurs simultaneously.

When unlocking, so that the first 6 and second parts 7 of the case do not separate, two technical solutions are used. The first technical solution is that in the first part 6 of the housing, the pin 12 is additionally provided with a groove 17, where the ball 18 with the spring 19 and the screw plug 20 are located, the ball 18 partially protruding from the groove 17 under the action of the spring 19, in the mating female part 13 the second part 7 of the housing in the socket 13 has a recess 21 under the ball 18, the assembled ball 18 is in the recess 21 and fixes the first 6 and second 7 parts of the housing. The second technical solution for fixing two parts 6, 7 of the housing is that the pin 12 is inserted into the socket 13 with an interference fit, to disconnect the first 6 and second 7 of the housing requires a certain user effort.

The locking means 4 (Fig. 1, 3, 4) of the specified power unit 3 is designed to set the elements of the power unit in the position: locked or unlocked by the forces exerted by the user by installing the "U" -shaped arm 8 in the inlet openings 22 of the housing 5 to the stop in the piezoelectric generator 23 with the butt-end 10 of the handle, as well as the removal of the handle 8 from the inlet 22 of the housing 5 of the lock 1 when unlocked.

Locking and unlocking is carried out using the means 24 (Fig. 1, 3, 4, 5), which controls the movement of the elements of the locking means, for example a piezoelectric actuator 24, by commands from the electronic control means 25 (Fig. 1, 3, 4) of the lock 1. The main advantage of the piezoelectric actuators 24 is the accuracy of positioning - hundredths and even thousandths of a nanometer. In addition, they are reliable, durable, have excellent speed, develop high acceleration and combine a large developed effort with compactness. It is very important that the piezo actuators 24 do not have rotating and sliding parts, do not require lubrication and maintenance, are able to work at low temperatures. According to commands from the electronic control means 25, the signal processing and computing boards 26 (Fig. 3, 4), the output means 27 (Figs. 1, 3, 4 of the piezoelectric actuator 24 have coupling / disengagement with the grooves 28 (locking means 4) located in the end slider part 9 of the "U" -shaped bow 8, the end 10 (Fig. 3, 4) which is equipped with a chamfer 11 (Fig. 1, 3, 4). The output means 27 is a "U" -shaped pusher 29, the first shoulder 30 of the pusher 29 is connected with the piezoelectric actuator 24, and the second shoulder 31 is provided with a locking element 32 in the form of a protrusion 32 from the side of the bow groove 28. In this case, the protrusion 32 from the inlet opening 22 of the housing 5 has a curved surface 33 with the formation of a circular arc. From the rear, the protrusion 32 enters the groove 34 (Fig. 1) in the housing and abuts against the fixing spring 35, located in the groove 34. Two piezoelectric actuators 24 (Fig. 1, 3, 4, 5) are located in the pocket 36 (Fig. 1) of the housing 5. The electronic padlock 1 (Fig. 1, 3, 4, 5) contains an electronic sensor position 37, and the electronic position sensor 37 has one triaxial microelectromechanical accelerometer 38 (MEMS sensor) and one three-axis microelectromechanical angular velocity sensor 39 (MEMS sensor, DOS) located in the lower part 40 on the sensor board 41 under each other so that the sensitivity axis 42 (FIG. 1, 3, 5) along the X axis of the accelerometer 38 and the CRS 39 are directed in different directions, the sensitivity axes 42 (Fig. 1, 5) coincide along the Y axis, and the sensitivity axes 42 are directed in different directions along the Z axis (Fig. 4). The accelerometer 38 and the CRS 39 (Fig. 3, 4) are electrically connected to the electronic control means 25, where it gives a signal about the position of the lower part 40 of the lock 1 to the signal processing and computing board 26, then the electronic means 25 of the control of the lock 1, according to a predetermined the sequence and duration of movements along the trajectory 43 (Fig. 7) with rotations in space and / or spatial positions 44 of the lower part 40 of the electronic padlock 1. The electronic control means 25 is provided with a power source-drive 45 (Fig. 1, 5), for example, ion 45 torr, four supercapacitor 45 arranged in pockets 46 of the body 5, is installed near the rectifier board 47 (FIGS. 1, 3, 4). Electronic control means 25 (Figs. 3, 4) and a signal and calculation processing board 26 are installed in a niche of the housing 1 and secured with screws 48. In this case, the first 6 and second 7 parts of the housing can be provided with covers (not shown).

The choice of MEMS sensors 38, 39 is due to the fact that they do not have moving parts. This determines their high reliability and ability to provide stable readings in fairly harsh environmental conditions (temperature drops, shock, humidity, vibration, electromagnetic and high-frequency interference). The electronic lock 1 can optionally be equipped with waterproof silicone gaskets (not shown). The presence of an accelerometer 38 (for example, an accelerometer of the type ADXL 202, which reacts if the tilt of the lock changes faster than 0.5 degrees per minute) in the design of lock 1 allows you to install a transmitting device (not shown) on your mobile phone, if castle 1 has been visited several times in the wrong position, the transmitter calls the user, security or the police.

You can use the MEIS sensor ADIS 16488. The inertial measuring module MEMS ADIS16488 iSensor® is a fully-functional inertial measuring subsystem that includes a three-axis gyroscope, three-axis accelerometer, three-axis magnetometer and pressure sensor.

Electronic padlock 1 operates as follows.

The principle of operation of the device for simultaneous locking of two parts 6, 7 (Fig. 6a, 6b, 6c) of the housing. For fixing the first 6 and second 7 parts of the housing 5 between themselves, two technical solutions were used. The work of the first technical solution. In the first part 6 of the case, the pins 12 (Fig. 6a, 6b, 6c, 5) are aligned with the sockets 13 in the second part 7 (Fig. 6a, 6b, 6c) of the case and cover both parts 6, 7 of the case. In this case, four pins 12 in the first part 6 of the case enter four sockets 13 in the second part 7 of the case, and four pins 12 of the second part 7 of the case go into four sockets 13 in the first part 6 of the case. The protruding part of the ball 18 in the pin 12 first enters the groove 17 of the pin 12, then, falling into the recess 21 under the action of the spring 19, the ball 18 enters the recess 21 and fixes both parts 6, 7 of the housing. In the second technical solution for fixing the two parts 6, 7 of the housing, the pin 12 is tightened into the socket 13 and under the action of the friction force both parts 6, 7 of the housing are fixed.

For locking, the user has in front of him a body 5 (Fig. 1, 3, 4) and an “U” -shaped handle 8. At the beginning, the user enters an “U” -shaped handle 8 into the eye 2 (Fig. 1, 2, 7), then two slide parts 9 (Figs. 1, 3, 4) of the bow 8 installs in the inlet openings 22 of the housing 5 and squeezes it to the stop, applying a certain force, i.e. the piezo generator 23 compresses the end face of the bow 8. The piezoelectric generator 23 generates electricity from squeezing, then the electricity is supplied to the rectifier 47, and then to the storage device 45 (Fig. 1, 3, 5), for example, the ionistor 45. The lock 1 is equipped with a device for simultaneous locking of the bow 8 (Fig. 6a, 6b, 6c), two parts 6, 7 of the housing. The device starts to block as the slider part 9 of the darling 8 passes through the inlet 22 of the housing 5 and completely blocks upon contact with the piezoelectric generator 23 (Figs. 1, 3, 4) of the butt 10 of the bow 8 as follows: as soon as the slider part 9 (Fig. 6a, 6b, 6c) of the bow 8 will pass through the holes 14 in the pin 12 of both parts 6, 7 of the body — the housing 5 is blocked as soon as the chamfer 11 (Figs. 1, 3, 4) of the end 10 of the bow 8 reaches the curved surface 33 of the protrusion 32 of the fixing element 32, curved surface 33 creeps through chamfer 11 onto slider portion 9 the bow 8 overcoming the action of the spring 19, as soon as the protrusion 32 is opposite the groove 28 of the end slide part of the bow 8, the protrusion 32 enters the groove 28 under the action of the spring 35 and locks the bow 8, locking the lock 1, two parts 6, 7 were blocked (Fig. 6a 6b, 6c) of the housing and lock 1 (Figs. 1, 3, 4).

Opening the castle 1 (Fig. 2). The lock 1 is programmed so that in the hanging position, i.e. in the position of the pendulum 44, the electronic position sensor 37 gives a signal about the position of the lock 1 of the circuit board 26 (Fig. 3, 4) of the signal processing and computing, then the electronic control means 25 of the control, which gives a signal to turn off the piezoelectric actuator 24, i.e. in this position the lock is always closed. To open the lock 1 (Fig. 2), many possible positions 44, 44.1, 44.2, 44.3, 44.4 or movements along a certain path 43 (Fig. 7) of the lower part 40 (Fig. 1, 3, 4) of the lock 1 ( Fig. 7), the user can program these variants of the position and movement algorithms before fixing the two parts 6, 7 (Fig. 3, 4) of the housing.

The first example. Sequential position in the form of a cross, you can lay the time interval of positions without the time parameter, it depends on the user. In the initial position of the lock 1 (Fig. 2), the lower part 40 of the castle 1 is facing down, the position of the pendulum 44. The lower part 40 of the castle 1 will be raised to the position 44.1 horizontally, the lower part of the castle 1 is facing the user and hold, for example, 3 seconds, then the lock 1 turn left, the lock position 44.2 is horizontal, the lower part 40 is facing the user to the left, hold in this position for 2 seconds, then to the right, the lock position 44.3 is horizontal, the bottom part 40 is facing the user to the right and hold 1 second, then up vertically, position 44.4 of the vertical lock, the bottom portion 40 facing up and hold for 5 seconds. In this case, the electronic position sensor 37 (Fig. 3, 4) gives a signal about the positions of the lock 1 to the signal processing and computing board 26, then the electronic control means 25, which gives a signal to turn on two piezoelectric actuators 24 (Fig. 1, 3, 4 ) The piezoelectric actuator 24 through the pusher 29 displays the locking element, i.e. the protrusion 32 from the groove 28 of the bow 8, overcoming the action of the spring 35, unlocks the bow 8, the user removes the bow 8, (Fig. 1, 2, 7) from the eyes 2 of the object.

An example of the second. In the initial position 44 (Fig. 7) of the lock 1, the lower part 40 of the castle is facing down, the position of the pendulum 44. The lower part 40 of the castle 1 is moved along a certain volumetric path 43, for example, a path in the form of the letter "S" 43. The user, moving along the path in in the form of the letter "S" 43, will reach the end point of the trajectory, in this case the position of the castle is vertical 44.4, the lower part is facing up. In this case, the electronic position sensor 37 (Fig. 3, 4) gives a signal about the positions of the lock 1 along the path 43 (Fig. 7) at a certain interval to the signal processing and calculation board 26 (Fig. 3, 4), then the electronic control means 25 , which gives a signal to turn on two piezoelectric actuators 24. The piezoelectric actuator 24 (Figs. 1, 3, 4) through the pusher 29 displays a locking element, i.e. the protrusion 32 from the groove 28 of the bow 8, overcoming the action of the spring 35, unlocks the bow 8, the user removes the bow 8 (Fig. 1, 2, 7) from the eyes 2 of the object, the lock 1 will open.

It is possible to charge the storage device 45 (Figs. 1, 3, 5) before opening the lock 1, squeezing the bow 8 or the housing 5, electricity is supplied from the piezoelectric generator 23 to the rectifier 47, and then to the ionistor 45.

In this case, the user has many algorithms for the positions or movements of the lower part 40 (Fig. 2, 7) of the lock 1 known only to him.

If the lock 1 is in an unauthorized position, thanks to the position sensor 37 (Fig. 1, 3, 4, 5) (accelerometer 38, DUS 39) and a transmitter (not shown), the user will instantly receive a notification, for example, to a mobile phone.

In contrast to the prototype, where the electronic position sensor gives the position of the moving element in the lock structure relative to the components of the lock, in the proposed technical solution, the electronic position sensor, consisting of one three-axis accelerometer and one three-axis angular velocity sensor (DLS) located in the lower part of the castle, where it gives a signal about the position of the lower part of the lock to the electronic control device of the lock, equipped with a signal processing and calculation board in a predetermined sequence and lzhitelnosti movements along a path with bends in space and / or the spatial position of the electronic padlock which provides opening and closing of the lock without using a key or other objects for opening and closing the electronic padlock.

In contrast to the prototype, where part of the housing fastening elements, functional elements for opening and closing the lock are located on the outer part of the castle body, in the proposed technical solution the castle body is equipped with a device for simultaneous locking / unlocking of the castle and two parts of the case, which is carried out inside the castle by two sliders parts of the handle placed in the holes of the pins of both parts of the case, from the outer part of the lock case there are no external functional elements, which increases the reliability of the design.

This technical solution allows you to not use keys and other items to lock and open the lock, the case is locked from the inside with a slide part, i.e. Outwardly, there are no functional elements, everything is “pure”, any design decisions are possible.

From the above it follows that this device is industrially applicable and solves the technical problem: creating a reliable design of an electronic padlock without using a key and other items to open and close an electronic padlock, locking / unlocking the lock and two parts of the case at the same time.
