Description

The utility model relates to mechanical anti-theft devices of automobiles and is intended to prevent their unauthorized use (theft).

There are various mechanical anti-theft devices that block access to car controls, the engine, or that prevent you from starting movement (RF patents for inventions No. 224643, 2416535, utility model patents No. 20645, 7643, 24431, 81928, 104123, etc.). These are devices that block the gearbox, hood lock, steering wheel, pedal assembly, starter, wheels, and consist of a protective housing of various designs (protective shell) and fasteners, which are often used as shear bolts or shear nuts. All of these safety devices are key locked. However, car thieves easily learned to crack these devices without using rude tools. In addition, some of them, in particular, the hood lock, must be serviced (lubricated, adjusted).

A known method of preventing theft of a vehicle and a device for its implementation (patent IL No. 182360 dated 01.04.2007, 118 No. 12162805 dated July 31, 2008), including packaging at least one vital component of the vehicle, namely the electronic control unit of the car located under the hood into the anti-theft device of the vehicle, which is a casing designed in such a way that the unauthorized removal of the specified casing causes an increase in anti-theft Sobienie of said protective device. This is achieved due to the fact that the casing is made in the form of an airtight aluminum alloy box closed on all sides, the casing elements are fastened together by shear bolts with right and left threads made of steel with increased strength. The computer is inserted into the box and then its parts are interconnected by stall bolts. When breaking under the influence of thermal and chemical treatments, the steel becomes harder, which makes it impossible to drill bolts with a drill. The combination of left and right threads creates additional difficulties for car thieves. The stall bolts are recessed into the casing of the safe, which also makes it difficult to remove them. The disadvantages of the device is that the ECU is not connected either with the casing or with the car body, which facilitates its dismantling, its high cost, as well as the absence of ventilation holes in the structure, which leads to heating of the electronic unit.

In a modern car, there are several control units: an electronic engine control unit located under the hood of the car and an engine switching unit or an engine system interface unit (BSM unit), which is located in the car interior. From the BSM block, all the control of the car's electrical circuits diverges. It provides protection and distribution of power to various nodes, a plate through a relay, conventional fuses and fuses designed for maximum current.

The BSM block is very convenient for installing an additional alarm or an additional immobilizer, that is, any anti-theft device, it has all the necessary outputs for this. Having completed all the connections at the BSM unit, the installer hides the electronic alarm unit or immobilizer on the length of the wire and antenna.

Car thieves know where all the connections and locks of anti-theft electronic systems are located. They jam the signals by various devices, then open the car with various master keys, keys, scanners, find electronic anti-theft devices (alarm blocks and additional immobilizers) and blocking relay circuits, turn them off and start the car. Knowing all the connection schemes, attackers easily steal a car.

It is necessary to create a mechanical obstacle to the access of the BSM unit and its connectors. The developed mechanical anti-theft system protects the BSM unit itself, the alarm unit or immobilizer connected to it, as well as their connectors from unauthorized breaking. Thus, hijackers do not have the opportunity to bypass the lock and throw the supply wires to the blocked systems.

The inventive utility model, as well as known, consists of a protective housing and fasteners.

The objective of the utility model is to expand the range of mechanical anti-theft devices designed to protect the vehicle control unit (BSM unit) from unauthorized entry.

The technical result consists in providing reliable protection of the vehicle’s BSM unit, an alarm unit or an immobilizer connected to it, as well as their connectors against unauthorized entry, simplifying the manufacture and installation of an anti-theft device and, accordingly, reducing its cost, as well as preventing overheating of the BSM unit .

The technical result is achieved by the fact that the body is made of at least two parts rigidly connected to each other, each of which has holes for fasteners, blocks access to the engine switching block (BSM block) of the car and its connectors, includes a shelf (strap or protrusion) to accommodate an electronic anti-theft system, has cutouts for wire connectors and openings for ventilation of the engine switching unit, made of cold-rolled or structural steel sheet, upper wall of the housing and made stepped.

Parts of the housing can be interconnected by shear nuts or shear bolts. The housing can be rigidly connected to the car body with the help of shear nuts. Holes for ventilation can be made in the upper wall and in the shelf.

Implementation of a utility model.

The design of the claimed anti-theft device depends on the make and model of the car, namely, on the specific design of the BSM and on its location in the car. Therefore, the protective housing is made of various specific designs.

The inventive utility model is illustrated using the drawings. In FIG. 1 shows one part of an anti-theft device made for a car of the Chevrolet Cruze and Opel Astra J models, FIG. 2 - the second part of this device.

The anti-theft device is a protective case made of two, rigidly connected to each other, parts 1 (Fig. 1) and 2 (Fig. 2). Each of parts 1 and 2 has openings 3 for fasteners (not shown in the drawing). Part 1 of the housing includes a shelf 4 (bar or tab) for accommodating any selected electronic anti-theft system (not shown in the drawing), has cutouts 5 for connectors. In the upper wall 6 of part 1 of the housing, holes 7 are made for ventilation of the engine switching unit. Holes 7 for ventilation are also made in the shelf 4. The upper wall 6 of part 1 of the housing is made stepwise. Parts 1 and 2 of the housing can be interconnected by shear nuts or shear bolts (not shown). The housing can be rigidly connected to the car body with the help of shear nuts. The case is made of cold rolled sheet steel or structural steel. The thickness of structural steel is at least 2.5 mm. The thickness of cold rolled steel is also 2.5 mm.

The execution of the housing from two, rigidly connected to each other, parts 1 and 2, each of which has openings 3 for fasteners and the connection of parts 1 and 2 of the housing together by detachable nuts or detachable bolts provides reliable protection of the BSM unit and the alarm unit or immobilizer, connected to it, as well as their connectors and simplifying the manufacture and installation of an anti-theft device.

The presence of the shelf 4 and the implementation of the upper wall 6 of the part 1 of the step housing provides the convenience of placing any electronic anti-theft system.

The presence of cutouts 5 for connectors allows all necessary connections to the BSM unit.

The presence of holes 7 for ventilation in the upper wall 6 of part 1 of the housing and in the shelf 4 ensures the prevention of overheating of the BSM unit and the alarm.

The rigid connection of the protective housing with the car body with the help of shear nuts contributes to the reliable protection of the BSM unit and its fixation.

Using the utility model is as follows.

After completing all the connections, insert the BSM block into most of the protective casing 1, place a block of any selected electronic alarm or other anti-theft device on a special shelf 4, and use the stall nuts or bolts to attach the second, made in the form of a bracket, part 2 of the casing. Then the anti-theft device is fixed with the help of stall nuts or bolts to the car body at the previous location of the BSM block.

This mechanical anti-theft device is easy to manufacture and install, inexpensive, provides reliable protection for the vehicle’s BSM unit, its connectors and electronic anti-theft system from unauthorized entry and prevents the unit from overheating. 5
