Abstract

FIELD: automotive industry.

SUBSTANCE: invention is designed for use in vehicles to prevent unauthorized use or theft. It can be used in electrical systems of vehicles to switch on different units and mechanisms which are connected with antitheft device. Proposed ignition lock with antitheft device has housing with removable clamp enclosing fixed base member of vehicle which accommodates movable locable part, clamp fastening members made in form of fastening rod fitted in hole of housing and mated with holes in clamp, spring-loaded cross bar of antitheft device. Cross slots made on cylindrical surface of fastening rod and on cross bar are designed for relative interlocking to prevent demounting of fastening rod and clamp when cross bar is in operating position. Novelty is that fastening rod is made with member providing its turning by wrench, with two different-diameter seat necks made coaxially relative to each other and eccentrically relative to fastening rod for mating with holes in clamp. Hole in housing is blind, with stepped reduction of diameter in depth. Blind slots made in housing are designed for fitting ends of clamp, and cross slot on fastening member is made circular, enclosing cylindrical surface of fastening rod.

EFFECT: improved rigidity of construction and reliability in operation.

Description

The invention relates to the equipment of vehicles to prevent unauthorized use or theft and can be used in electrical systems of automobiles to turn on various components and mechanisms associated with an anti-theft device.

Known locking devices consisting of locking elements of its moving parts in conjunction with mating parts, fixed relative to them with the possibility of feeding the fixing elements of the above parts using a rotary key, for example, according to application No. 95110994/28 and RF patents No. 2200101, No. 2176200, cl . B 60 R 25/02.

Known ignition switch with anti-theft device according to the patent of the Russian Federation No. 2174078, class. B 60 R 25/02, comprising a housing with a removable clamp covering the stationary body element of the vehicle in which the movable lockable part is placed, the clamp fastening elements are made in the form of a mounting rod located in the housing opening and mating with the holes in the clamp, and a spring-loaded bolt anti-theft mechanism, a recess is made on the cylindrical surface of the mounting rod, in which the crossbar is placed in the working position - part of its outer surface, and the cross groove is made on the crossbar along EAUTC fastening arrangement in the retracted position of the rod pins so that the fixing rod can be removed only in the retracted bolt position.

This device is the closest in design to the claimed technical solution and we have taken for the closest analogue.

The disadvantages of the closest analogue include:

- insufficiently rigid design at the junction of the clamp with the body and the body element of the vehicle due to the presence of guaranteed clearance in the pair;

- low resistance of the housing and the clamp to destructive effects.

The objective of the technical solution is to increase the rigidity of the structure and reliability in operation.

To solve this problem, in the ignition switch with an anti-theft device, comprising a housing with a removable clamp covering the stationary body element of the vehicle, in which the movable lockable part is located, clamp fastening elements made in the form of a mounting rod placed in the housing opening and mating with holes in clamp, spring-loaded deadbolt of the anti-theft mechanism, transverse grooves are made on the cylindrical surface of the mounting rod and on the bolt for interlocking from the possibility of dismantling the fixing rod and the clamp in the working position of the bolt, the fixing rod is made with a turnkey element that allows it to be rotated, with two landing necks of different diameters, made coaxially with respect to each other and eccentric with respect to the fixing rod, for interfacing with clamp holes, the hole in the housing is blind and stepwise with a decrease in diameter in depth, blind grooves are made in the housing to accommodate the ends of the clamp, and the transverse groove on the fastener e is made annular, covering the cylindrical surface of the mounting rod.

Figure 1 shows the proposed ignition switch with anti-theft device, axial section.

In Fig.2 is a section aa in Fig.1.

The ignition switch contains a housing 1 and a removable clamp 2, covering the stationary body element 3 of the vehicle, in which a movable lockable part 4 is placed, a locking device 5 with a key 6, and a bolt 7 designed to interact with the locked part 4 in the anti-theft mode, spring-loaded using a spring 8. At the ends 9 and 10 of the clamp 2, holes 11 and 12 of different diameters are made, grooves 13 and 14 are made in the housing 1 to accommodate the ends 9 and 10 of the clamp 2 in them, as well as a blind step hole 15 with a decrease in diameter Loubinoux, in which a fastening rod 16 is formed with two landing necks 17 and 18 of different diameters. The necks 17 and 18 are made eccentric with respect to the mounting rod 16 and coaxially with each other. The end 19 of the fixing rod 16 is provided with an element 20 that allows the fixing rod to be rotated using a standard wrench or a screwdriver, for example a turnkey head. An annular groove 21 is made on the fastening rod 16, in which the crossbar 7 is placed in the working position with a part of its outer surface 22. A lateral groove 23 is made on the crossbar 7 at the location of the fastening bar 16, so that the fastening bar 16 can only be removed in the retracted position of the crossbar 7 (not shown in the devil).

Device operation

The device is mounted on the vehicle at the location of the locked part 4.

By rotating the fastening rod 16 due to the eccentricity of the necks 17 and 18 relative to the fastening rod 16, all gaps are selected and a certain interference is created in the mates of the fastening element with the housing 1 and the clamp 2, as well as the clamp 2 with the stationary hull of the vehicle 3, thereby achieving total rigidity designs. In the position of the crossbar 7 shown in FIG. 1, it blocks the part 4, while the groove 21 prevents disassembly of the mounting rod 16.

To unlock the part 4 by turning the key 6 of the locking device 5, the bolt 7 is retracted from the part 3. In this case, the transverse groove 23 on the bolt 7 is shifted towards the opening of the groove 21 on the mounting rod 16.

To dismantle the lock with the anti-theft device in the unlocked position of the bolt 7 by rotating the fixing rod 16 with a wrench (not shown in the drawings), the tension is released, after which the fixing rod 16 can be removed, and then the whole device is disassembled.
