Description

The invention relates to the field of hardware and relates to a device for the automatic unlocking of key locks of lever type and can be used both for unlocking locks and to determine the parameters of their code combinations.

A device for unlocking locks (patent for invention No. 2361050, IPC EV 05/19, 2009), consisting of a housing, a lever, fixedly mounted in it, and a cylindrical probe with rectangular protrusions at the end. Similar features of this device with the claimed technical solution are a lever that creates an interference fit on the deadbolt, as well as a probe installed in the housing with the possibility of axial movement and rotation. A disadvantage of the known device is that the unlocking and determination of the code combination is entirely dependent on the operator.

The closest analogue, selected as a prototype for the maximum number of matching features, is a device for unlocking locks (patent for utility model No. 101070, IPC E05B 19/20, 2010).

The device contains a housing, a pusher and a probe. The housing has the shape of a cylinder, a pusher in the form of a round rod, having a flat protrusion at the end, a probe representing a round stepped tubular-shaped rod with a flat protrusion. The pusher is equipped with a rotation drive, and the probe with a rotation drive and a linear displacement drive, while the probe is made of several mutually movable parts and is equipped with sensitive elements. All drives for the rotation of the pusher, the rotation of the probe, the linear movement of the probe are equipped with position sensors. The design of this device provides automated unlocking and determination of code combinations of lock devices of a lever type of a certain design.

Common features of the claimed invention with a prototype are: a housing, a pusher, a probe with moving parts and sensitive elements, angular and linear displacement drives, position sensors.

The disadvantage of the prototype is that when changing the power and control parameters of the electric motor (even short-term), which creates a constant load on the bolt of the lock or its failure, a temporary change in its value occurs, which leads to a loss of the achieved result on the position of the levers and information about the code combinations, as in this case the levers occupy their original position under the action of their springs.

The tasks to which the proposed technical solution is directed are the possibility of creating a constant load on the bolt of the lock, independent of changes in the power and control parameters of the electric motor, as well as eliminating backlashes, which allows to obtain a stable result when unlocking and determining the code combination of the lock device.

The technical result obtained by applying the claimed invention consists in the possibility of creating a constant load on the bolt of the lock.

To achieve the specified technical result, a lock unlocking device comprising a housing, a composite probe with sensitive elements, coaxially mounted on the pusher with the possibility of axial movement and rotation, a pusher rotation drive, a probe rotation drive, a probe linear motion drive, a pusher compensation compensation mechanism is introduced, located between the pusher and its drive. The compensation mechanism can be made in the form of two flanges interconnected through a bearing and a spring installed between them.

A distinctive feature of the proposed device for unlocking the locks from the above known, closest to it, is the introduction of a compensation mechanism that sent the bolt and its placement between the bolt pusher and the electric motor.

Due to the presence of these features, the claimed technical result is achieved, the achievement of which is impossible in known similar devices and, in particular, in the prototype.

The proposed device for unlocking the locks is illustrated by the drawings shown in figures 1-4.

Figure 1 presents a General view of a device for unlocking locks; figure 2 is a General view of the device in section; in FIG. 3 - a general view of the probe in the context; figure 4 - compensation mechanism has sent the deadbolt in the context.

The device for unlocking locks comprises a housing 1 having the form of a stepped cylinder. On one side, a probe 2 protrudes from the housing 1, through which the pusher 3 passes. The pusher 3 is a cylindrical rod with a flat shank 4. On the opposite side, motors 5, 6, and 7 are installed. To register the angular positions of the probe 2 and the pusher 3 in the housing 1 there are position sensors 8, 9 and 10. The probe 2 consists of two parts interconnected via a bearing 11, between these parts a force sensor 12 is installed to record the threshold force values, a spring 13 to provide a given clearance and a screw 14 for adjusting wki clearance. On the axis of the probe 2, a through hole is made through which the pusher 3 passes. On the opposite side, the probe 2 has two T-shaped protrusions that are connected to the gear wheel 15, to which torque is transmitted from the electric motor 5 through the pinion shaft 16. On the axis a position sensor 8 is mounted on the pinion shaft 16. A nut 18 is installed on the gear wheel 15 through the bearing 17 and includes a screw 19 for linear movement of the stylus 2. The bearing 17 allows the gear wheel 15 to rotate independently of the nut 18. The screw 19 transfers I rotation from the electric motor 6 through gears 20 and 21. A position sensor 10 is installed on the axis of the screw 19. In the housing 1, a pusher 3 is mounted coaxially with rotation on the bearing 22, which is rigidly connected to the gear wheel 23. The torque from the electric motor 6 to the gear the wheel 23 is transmitted from the pinion shaft 24 through a compensation mechanism that is installed between the electric motor 6 and the pinion shaft 24. The compensation mechanism consists of two flanges 25 and 26 connected to each other through a bearing 27 and installed between the flange pins ncev 25 and 26 of the spring 28. An angle sensor 9 is mounted on the axis of the gear 24.

The operation of the device for unlocking the locks is as follows. The probe 2 is inserted into the key well until the stop. Turning on the electric motor 7, the flange 26 is turned. Due to the created torque by the electric motor 7, they act on the spring 28, which is compressed and transmits constant torque to the flange 25, thereby ensuring the stable operation of the device. From the flange 25, rigidly connected to the gear shaft 24, the torque is transmitted to the gear 23 and the pusher 3, turning it until the shank 4 contacts the lock bolt. The angular position of the pusher 3 is determined using the sensor 9. Having created an interference fit on the bolt, they begin to act on the levers with the help of the probe 2, which is driven by the electric motor 5, through the gear wheel 15 and the pinion shaft 16.

Given the errors in manufacturing parts of the lock, as well as the fact that even the same dimensions of the code levers differ during manufacture within the specified tolerances, the determination of the presence of a clearance and tightness of the levers is provided. In the presence of interference, the suvald moves with tangible difficulty. The value of the force exerted on the gauge by the probe 2 is registered by the force sensor 12, as soon as the force value is significantly reduced, the force sensor 12 detects this drop, and the electric motor 5 stops. The position of the probe 2 is currently determined using the sensor 8, this position corresponds to the known standard size of the code level. The probe 2 is returned to its original position and is axially moved to the next level with the help of an electric motor 6, through the screw 19 and nut 18, this position is determined using the sensor 10. Using the probe 2 on each level, determine the greatest interference and affect it to a significant reduction of effort, and so on until the castle is opened. The determination of the position of the probe 2 using the sensor 8, at the time of opening the lock, makes it possible to determine the parameters of the code combination. The information obtained in the process of unlocking the lock on its code combination allows you to make a duplicate of the original key.

Introduction to the device for unlocking the locks of the compensation mechanism of the push rod 3 allows you to create a constant load on the bolt of the lock and get a stable result when unlocking and determining the code combination of the locking device, regardless of changes in the power and control parameters of the electric motor or its failure. Also, the compensation mechanism eliminates the dependence of backlash in the device on the unlocking process and determining the code combination.
