Description

The invention relates to the field of engineering, in particular to a technique for preventing theft of vehicles. To achieve high protection against theft, it is recommended to install alarm devices and mechanical anti-theft devices on the car. Modern car alarm systems are controlled from a key fob, have high security from code selection and block the electrical circuit from starting the engine. However, such protection is not enough, and to increase the protection against theft on the car, mechanical anti-theft devices are installed, which are of three types: a lock on the hood, a lock on the steering wheel, a lock on the gearbox.

Known anti-theft device of the vehicle (RF patent No. 2041087, IPC (6) B60R 25/00), comprising a housing with a locking mechanism for locking the parking brake lever and a grip for locking the gear lever mounted on the housing. A disadvantage of the known technical solution is that it is bulky, violates the interior of the car, it is difficult to install and inconvenient to use due to the fact that when locking and unlocking you must use the key lock device.

A device is known for preventing unauthorized use of a vehicle and a lock for a gear lever (RF patent No. 2052360, IPC (6) B60R 25/06, B60R 25/00). In the known device, inside the lock case there is an auxiliary anti-theft unit installed with the possibility of switching when locking and unlocking the lock. Its activation is carried out by introducing a locking handle into the lock case, and deactivation by its removal, the lock for the gear lever is made with a key hole and placed on a mounting plate attached to the vehicle chassis. The disadvantages of the device include design complexity, unreliability and inconvenience in operation, because the lock has a key hole. In addition, the lock is placed on the mounting plate attached to the chassis of the vehicle, which changes the interior of the car.

The closest technical solution is the automatic anti-theft system CTL # 57-D HL-LOCK, designed to lock the gearshift mechanism of the car (see the appendix - “CTL # 57-D HL-LOCK. User's manual”). The system contains: a remote unit for transmitting command code information interacting via a communication channel with a receiving electronic control unit, an actuator located on a plate under the console in the immediate vicinity of the gearbox, and a reader located separately in any place convenient for the driver of the car. The actuator includes a receiving electronic control unit, an electric motor with a gearbox that moves the locking pin located in the mechanical lock housing, an electronic circuit for tracking the extreme positions of the locking pin, an audible signaling mechanism.

The disadvantages of the system are:

- the complexity of the design of the castle and its management, involving the use of a special electronic circuit;

- low reliability of the device;

- inconvenience in operation associated with the use of a mechanical key;

- the complexity of installing the system, due to the need for bending and fitting the plate on which the lock is installed;

- the complexity of installing the system, caused by the need to cut holes for the lock cylinder, which, in addition, violates the interior of the car;

- high price.

The technical task of the invention is the creation of a simple, reliable, cheap and convenient to install and operate an anti-theft system.

The technical result is to increase the protection of vehicles from theft.

The claimed technical result is achieved in that the anti-theft complex includes a command code information transmission unit interacting via a communication channel with a receiving electronic control unit, for example, a central car alarm unit, and an actuator.

The actuator comprises an electromechanical lock, a signal mechanism, for example an indicator lamp, which allows you to monitor the state of the lock in the "open" - "locked" position, connected to the signal mechanism sensor located in the housing of the electromechanical lock. An electromechanical lock is placed in the immediate vicinity of the gearbox under the console.

The electromechanical lock includes a housing with a cover in which two electromagnets are located, a signaling mechanism sensor, for example, a limit switch, a locking pin and a lock. The locking pin, made in the form of a spring-loaded core of the electromagnet, is mounted with the possibility of reciprocating motion and consists of two parts - a tip made of steel with no magnetic properties, and a shank made of steel with magnetic properties. A washer is located under the coil of the electromagnet. Holes with a diameter corresponding to the diameter of the pin and guiding its movements are made in the washer and cover of the lock case.

The locking of the locking pin of the electromechanical lock in the locked position is provided by a spring-loaded lock made in the form of a plate mounted with the possibility of reciprocating movement in the direction perpendicular to the movement of the locking pin and connected to the core of the second electromagnet. The position of the lock is controlled by a sensor of the signal mechanism, made, for example, in the form of an end push-button switch, the location of the latter inside the lock case is fixed by a lock ring.

Due to the design features of the electromechanical lock of the claimed anti-theft complex, the lock is brought into the “open” or “locked” position using commands issued from the command code information transmission unit, for example, from a car alarm key fob. Therefore, the claimed complex does not provide for the presence of a larva of the castle and, therefore, manipulations with the key.

The case of the electromechanical lock is made of carbon steel, the receiving electronic unit is placed in a case of similar steel. This makes it impossible to use an electric drill or the like. means for their destruction or unlocking.

The electromechanical lock is placed on a special bracket, developed individually for each model of the car, and is mounted with the help of stall bolts under the car console in the immediate vicinity of the gearbox.

Figure 1 shows the wiring diagram of the anti-theft system, figure 2 shows the electromechanical lock in the "open" position, figure 3 - the electromechanical lock in the "locked" position, figure 4 is a circuit diagram of the anti-theft system.

The anti-theft system includes a command code information transmission unit (not shown), a receiving electronic unit containing a central unit 1, a locking relay 2, a digital unlocking relay 3, an actuator including an electromechanical lock 4, a signal mechanism 5. The electromechanical lock 4 consists of a housing 6 with a cover 7, in which an electromagnet 8 is placed, a locking pin 9, consisting of a tip 10 and a shank 11 with a spring 12, a washer 13, a limiter 14, a second electromagnet 15, a core 16 with a spring 17 to which is connected n lock 18, washer 19, limit switch 20, consisting of a base 21, a button 22, a spring 23, a terminal 24, a lock ring 25. An electromechanical lock 4 and a digital unlocking relay 3 are exchanged on an arm 26, which is mounted under the bolts 27 under car console.

The anti-theft system works as follows.

From a remote unit for transmitting command code information - from a car alarm key fob, for example Pharaon VI8 (Korea), the signal is sent to central unit 1 - the car is armed. From block 1, through a locking relay 2, a voltage of 12 volts hits an electromagnet 8 (pulse duration - 1 s). In this case, the locking pin 9 due to the shank 11, made of steel with magnetic properties, is drawn into the coil of the electromagnet 8. The tip 10, made of steel, not having magnetic properties, extends through the hole in the cover 7 of the housing 6 of the electromechanical lock 4, blocking the movement of the handle gear shift 28, while the spring 12 is compressed, the limiter 14 moves to the washer 13 located under the coil of the electromagnet 8. The lock 18 under the action of the spring 17 moves under the locking pin 9 and fixes the electric romehanichesky lock 4 in the "locked" position. In this case, the spring 23 shifts the button 22 and the terminal 24 closes the circuit, the indicator lamp 5 lights up. The anti-theft system is in the locked position, the gear shift knob 28 is locked.

To unlock the gearshift knob 28 and disarm the car, a signal from the car alarm key is sent to the central unit 1. Then, the third button of the car alarm is pressed, this signal is also sent to the central unit 1, which supplies an encoded signal to a digital relay unlocking 3, supply voltage of 12 volts (pulse duration 1 s) to the electromagnet 15. The core 16 is drawn into the coil of the electromagnet 15 and pulls the blocker 18. Under the action of the spring 12, the locking pin 9 returns to the starting position "open". Moving in the coil of the electromagnet 15, the core 16 presses the button 22, of the limit switch 20, which, overcoming the resistance of the spring 23, breaks the terminal 24 from the housing of the limit switch 20, the circuit breaks, the indicator lamp 5 goes out. The electromechanical lock 4 and the whole anti-theft system as a whole are in the “open” position. Shift knob 28 unlocked.

Currently, there is a constant improvement of electronic devices and a decrease in the size of car alarms.

To control the electromechanical lock, which is part of the declared anti-theft system, you can use almost any car alarm by placing its central unit in an armored case, instead of a digital relay.

The mechanical anti-theft device will be controlled by the relay of electric drives of door locks available in any car alarm.

The inventive anti-theft system is reliable in operation, because includes a car alarm system and an actuator containing an electromechanical lock with the ability to lock in the locked position, providing a high degree of locking the shift knob.

The inventive complex is convenient in operation, because pressing a button on a car alarm key fob combines arming and locking of the complex, and subsequently pressing the car alarm key fob disarms the car and pressing the key fob again brings the claimed system to the “open” position.

The lock has small dimensions, it can be easily inserted into the plastic case of the gearbox mechanism under the console without changing the interior of the car. The design of the lock is such that it does not require key manipulation and the presence of a lock cylinder, the insert of which into the console cover spoils the interior of the cabin.

The inventive anti-theft complex is protected from harmful external influences, because located in the passenger compartment.

The simplicity, reliability and ease of use of the inventive anti-theft system allow you to use it not only as an anti-theft system, but also to prevent unauthorized access to any object, for example, to lock gates, doors, safes, etc.

Studies on patent and scientific and technical sources of information have shown that the proposed complex is unknown in mechanical engineering and meets the criteria of “novelty” and “inventive step”.

The inventive anti-theft complex can be used to lock all types of gearboxes on cars, both passenger and freight, therefore, it is industrially applicable.

The claimed technical result - increasing the protection of vehicles from theft - is fully ensured by the use of the claimed anti-theft system.
