KR20020091550A - Burglarproof device for a car - Google Patents

Abstract

PURPOSE: An anti-burglar apparatus for a vehicle is provided to effectively prevent the vehicle from being stolen by allowing the vehicle to be maintained in a non-ignition state even if a burglar enters into the vehicle and tries to ignite the vehicle. CONSTITUTION: An anti-burglar apparatus includes a remote controller(1), which operates a solenoid actuator(3) installed in a vehicle in such a manner that a key cylinder(5) is rotatably switched. A locking hole(7) is formed in a circumferential surface of the key cylinder(5). The solenoid actuator(3) includes a locking plunger(9), which is inserted/withdrawn into/from the locking hole(7) so as to switch the rotational state of the key cylinder(5). The rotation of the key cylinder(5) is determined depending on the operation of the solenoid actuator(3). The solenoid actuator(3) is fixed in a key box supporting the key cylinder(5) so as to limit the rotation of the key cylinder(5).

Description

Vehicle antitheft device {BURGLARPROOF DEVICE FOR A CAR}

The present invention relates to an anti-theft device for a vehicle, and more particularly, to an apparatus for preventing theft of a vehicle by preventing the vehicle from starting even when the vehicle is broken into the vehicle.

Automobiles are subject to frequent theft accidents due to their high material value and easy transportability. Recently, the anti-theft device is almost indispensable in many medium and large vehicles. Various efforts have been made to minimize the risk of theft of vehicles.

Recently, among the anti-theft devices, a method of alarming a siren or a horn when theft is detected using an electronic time & alarm control system (ETACS) as shown in FIG. 1 is mainly used. For example, an apparatus for adopting an IMMOBILIZER system to determine whether a vehicle starts by encrypting an encryption code transmitted from a vehicle key with an ECU is used.

However, the above-described ETACS device alone does not have a sufficient countermeasure for professional theft. Even if the alarm sound is disabled, the starter of the vehicle inserts a key as shown in FIG. If it is possible to start the engine by rotating it, there is a possibility of deodorizing the vehicle relatively easily with imitation key or universal key.In the case of the immobilizer system, a separate coded transceiver is required. There is a problem that is a rising factor.

Accordingly, the present invention has been made to solve the above problems, and by using the ETACS device adopting the existing transmission and reception mechanism, even if invading the interior of the vehicle at a relatively low cost to prevent the start of the vehicle more secure The purpose is to provide a vehicle antitheft device that can perform the antitheft function.

The vehicle anti-theft device of the present invention for achieving the above object is a locking hole formed in the circumferential surface of the key cylinder, and a locking plunger for switching the rotatable state of the key cylinder by being inserted into and removed from the lock hole. And a solenoid actuator provided, and a control means for applying an operation signal to the solenoid actuator.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a block diagram showing a vehicle anti-theft device according to the present invention, the solenoid actuator (3) mounted in the interior of the vehicle receives a signal from the transmitter (1) for transmitting the operation signal operated by the vehicle owner A system is shown to operate the switch to cause the rotatable state of the key cylinder 5 to be switched.

That is, the locking plunger 9 is formed in the circumferential surface of the key cylinder 5 so as to switch the rotatable state of the key cylinder 5 by being inserted into and detached from the locking hole 7. By providing a solenoid actuator (3) having a), whether or not the rotation of the key cylinder (5) is determined according to the operating state of the solenoid actuator (3).

Of course, the solenoid actuator 3 is fixed to a key box (not shown) supporting the key cylinder 5 so as to suppress the rotation of the key cylinder 5 can suppress the rotation of the key cylinder (5). It is installed in a state, and a separate control means for the operation control is required, which allows the ETACS 11 mounted on a general vehicle and the ETACS 11 to remotely transmit a vehicle owner's operation signal to the ETACS 11. Composed of a transmitter 1 and a receiver 13, the transmitter 1 allows the vehicle owner to always carry it and generate an operation signal.

Referring to Figure 4 the operation of the present invention configured as described above are as follows.

Since the vehicle owner always carries the transmitter 1, when leaving the vehicle, the lock switch of the transmitter 1 is operated to prevent theft of the vehicle. When the driver operates the lock switch of the transmitter 1, The operation signal is transmitted from the transmitter 1 and received by the receiver 13, which is in turn transmitted to the ETACS 11 to cause the ETACS 11 to operate the solenoid actuator 3.

At this time, the solenoid actuator 3 is operated while the lock plunger 9 is inserted into the lock hole 7. Thus, in the state where the lock plunger 9 is inserted into the lock hole 7, Even when attempting to rotate the key cylinder 5 with a key or a universal key, the key cylinder 5 is in a state that cannot be rotated, thereby preventing the vehicle from starting.

As a result, it is possible to perform an excellent anti-theft function that effectively prevents theft of the vehicle even by a professional intruder who incapacitates the occurrence of an alarm sound of the ETACS-equipped vehicle and enters the vehicle.

Next, in order to operate the vehicle, it is necessary to release the lock state of the key cylinder 5 as described above by operating the transmitter 1, which means that the vehicle owner operates the opening switch of the transmitter 1 so that the key cylinder 5 ), And when the receiver 13 receives the open operation signal transmitted from the transmitter 1 and provides it to the ETACS 11, the ETACS 11 provides the solenoid actuator 3. It works.

In other words, the lock plunger 9 of the solenoid actuator 3 is released from the lock hole 7 of the key cylinder 5 so that the key cylinder 5 is rotated by a key operation of a person to be operated. By starting the vehicle will be able to operate the normal vehicle.

As described above, the vehicle antitheft device according to the present invention is disabled even when a vehicle having a vehicle antitheft function of a level that generates various alarm sounds and is infiltrated into the vehicle by infiltrating the inside of the vehicle by a pseudo key or a universal key. By preventing the system from starting up, the system can perform a more complete system anti-theft function.
