Description

Vehicle anti-theft system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-theft system provided in a vehicle. In particular, a pin is operated at a predetermined portion of a door by a driving force of a motor, and includes a non-pillar and a pillar. The pin is inserted into one side of the predetermined part to lock the door of the vehicle. When the key of the vehicle is not inserted into the door key cylinder, the pin is inserted into the hole by the reverse rotation of the motor to lock the door. The present invention relates to a vehicle anti-theft system for releasing the locking of the door by rotating the motor forward and removing the pin from the hole when the door key cylinder detects that the vehicle key is inserted.

In general, in order to prevent theft of a vehicle, an automatic alarm device is installed to generate an alarm sound when someone illegally occupies the vehicle from the outside, and at the same time, flashes the emergency light of the vehicle to alert the driver or people around the vehicle. Many automatic alarm devices are used to report theft of a vehicle.

However, the conventional automatic alarm device not only has a problem of causing noise pollution to people around it because it uses an alarm and an emergency light, and it is possible to open the door of the vehicle despite the operation of the alarm and emergency light, thus illegally making the vehicle illegal. If the occupant is to cut off the vehicle by temporarily stopping the operation of the automatic alarm device of the vehicle there was a problem that can not prevent.

Accordingly, the present invention has been made in order to solve the above problems, and provided with a pin (pin) to be operated by the driving force of the motor on one side of the door, non-pillar (B pillar) and sea pillar (C pillar) The pin is inserted into a predetermined part of the side to lock the door of the vehicle. When the key of the vehicle is not inserted into the door key cylinder, the pin is inserted into the hole by the reverse rotation of the motor to lock the door. When the vehicle key is inserted into the door key cylinder through an optical sensor, an object of the present invention is to provide a vehicle anti-theft system for releasing the locking of the door by rotating the motor forward and removing the pin from the hole.

It is characterized by consisting of a lock relay.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, a predetermined portion of one side of the vehicle door 1 includes a door switch 10 for detecting the opening or closing of the door, and a door key cylinder 2 for locking or opening the door 1. It is.

In addition, the predetermined position inside the door key cylinder 2 is provided with an optical sensor 20 that is integrally formed with the light emitting portion 21 and the light receiving portion 22 as shown in Figure 2, the light emitting portion Light transmitted from 21 may be received by the light receiving portion 22 to detect whether a key (not shown) is inserted into the door key cylinder 2.

When it is detected that the door 1 of the vehicle is closed by the door switch 10 provided at one side of the vehicle door 1, when the driver inserts a key into the door key cylinder 2, the optical sensor ( Since the light transmitted from the light emitting unit 21 of the 20 is blocked by the key to receive the light from the light receiving unit 22, the optical sensor 20 outputs an electrical signal, and the light sensor 20 The electrical signal is input to comparator 1 (31). The comparator 1 (31) generates a high signal when the electrical signal of the optical sensor 20 is greater than the reference voltage to prevent malfunction of the circuit. The transistor 1 32 is driven by the electrical signal of the comparator 1 31, and the relay switch 1 36 is operated by the switching action of the transistor 1 32. The relay switch 1 36 supplies power to the circuit to operate the timer ground switch 37, and the timer ground switch 37 supplies power to the motor 40 for a predetermined time.

As shown in FIG. 3, the motor 40 is provided at a predetermined portion of the inside of the door 1 and rotates forward while power is supplied by the timer ground switch 37 to generate driving force. A pin 41 coupled to one side of the motor 40 moves backward. A predetermined portion of one side of the B pillar 3 and the C pillar 4 of the vehicle is provided with a hole 42 into which the pin 41 can be inserted, and the pin moving backward. 41 is released from the hole 42 to unlock the vehicle.

In addition, when the ignition switch 33 for operating the starting device of the vehicle is operated, the relay switch 1 36 is directly connected through the comparator 2 34 and the transistor 2 35 regardless of the operation of the light sensor 20. The motor 40 is driven to operate, and the locking device of the vehicle is released by the operation of the motor 40.

In addition, when a key is not inserted into the door key cylinder 2 while the vehicle is detected that the ignition is turned off, the light transmitted from the light emitting unit 21 of the optical sensor 20 is received by the light receiving unit 22. Since the optical sensor 20 does not generate an electrical signal, the inverter 51 outputs a high signal, and the transistor 3 52 is driven by the high signal of the inverter 51. The switching action of 52 causes the relay switch 2 53 to operate. Power is supplied to the timer delay switch 54 by the operation of the relay switch 2 53, and the timer delay switch 54 supplies power to the motor 40 for a predetermined time. In the motor 40, when the power is introduced from the timer delay switch 54, the motor rotates in reverse to generate a driving force, and the pin 41 moves forward by the reverse rotation of the motor 40 so that the non-pillar 3 ) And the locking device of the vehicle is inserted into the hole 42 provided at one side of the seed pillar 4.

In addition, the vehicle is provided with a door central locking device relay 11, when the lock of the driver's side door is operated, the other three doors are also interlocked, and when the lock of the driver's side door is released, The three doors are also locked to unlock.

As described above, the vehicle anti-theft system according to the present invention includes a pin 41 that is operated by the driving force of the motor 40 at one side of the door, and includes a non-pillar 3 and a seed. The key 41 of the vehicle is inserted into the door key cylinder 2 having a hole 42 through which the pin 41 is inserted at one side of the pillar 4 to lock the door 1 of the vehicle. If not, the light sensor detects that the door 41 is locked by inserting the pin 41 into the hole 42 by reverse rotation of the motor 40, and that the vehicle key is inserted into the door key cylinder 2. If detected through 20, the motor 40 is rotated forward to release the pin 41 from the hole 42 to unlock the door so that the door of the vehicle is inserted into the door key cylinder 2 only. It is possible to open the car has the effect of preventing theft of the vehicle.
