Description

  The present invention relates to a vehicle anti-theft device, which identifies biometric features to a person sitting in a driver's seat and provides a handle lock function when an intruder enters the interior of the vehicle. It collects, issues an immediate alarm, and notifies the vehicle owner or security agency by wireless communication.

  The most basic anti-theft design of a general vehicle is to prevent the door from entering inside the vehicle by locking the door of the vehicle. However, most door lock structures are easily opened by intruders. In some cases, the window is broken and the vehicle is invaded, so another anti-theft device is necessary to prevent the vehicle door lock from being broken and stealing the vehicle.

  There is another type that locks to the handle of the car. However, since the structure of the known handle lock device only prevents the handle from turning, if the lock device is broken, the car can be easily stolen.

    The problem to be solved is that if the door lock or the handle lock device is broken, the car can be easily stolen.

  In the present invention, a lock part for holding the steering wheel and an image taking part are installed on the airframe. Besides, an IC chip matched by a control circuit is recorded inside the airframe to record the biological characteristics of the original driver. Compare the biometric features of the images of people sitting in the driver's seat. When it matches, the lock part opens immediately, and when it doesn't match, the handle is not released. Furthermore, the main feature is that the image record of the person sitting in the driver's seat is stored, the alarm is activated, and the relevant location is notified.

  The vehicle anti-theft device according to the present invention has an advantage that, in addition to having a handle locking function, an image of an intruder is collected, an immediate alarm is issued, and the vehicle owner or a security organization is notified by wireless communication.

  As shown in FIGS. 1 and 2A, the basic structure of the vehicle antitheft device of the present invention is a lock part 20 for stopping a handle 70 on an airframe 10, an image taking part 30 (CCD, CMOS sensor part, digital image taking part or similar parts). Image acquisition parts) are installed. In addition, a power supply circuit 41, a microprocessor 42, an IC chip 43, an image recording unit 44. A digital image processing circuit 45, a lock component drive circuit 46, an alarm drive circuit 47, and a control circuit 40 for the wireless communication module 48 are installed. The control circuit 40 is connected to a vehicle alarm (not shown).

  Both sides of the machine body 10 are mutually aligned with the control circuit 40 by a motor 50 controlled by a lock part drive circuit 46, and the lock part 20 is a sandwiching body that converts an angle by the rotation of the motor 50 (see FIG. 3). When the antitheft device is used, the body 10 is fixed near the handle 70 portion of the vehicle instrument base 60, and the lock component 20 does not form an angle for pressing the handle 70 when the vehicle antitheft device is not started.

  When the vehicle antitheft device is used, the control circuit 40 is interconnected with the door lock of the vehicle, and when there is a person who opens the door, as shown in the operation flowchart FIG. Take a picture of the seat direction. After the image of the person sitting in the driver's seat has been collected, it is compared with the biological characteristics of the original driver recorded by the IC chip 43. When the biological characteristics match the comparison, the motor 50 moves and the lock component 20 is moved. Remove from handle 70 to get ready for driving. On the other hand, if it does not match the biometric feature, the lock component 20 holds the handle 70 and immediately stores the image recording file on the driver's seat from the flash memory, the copier, and the hardware. Stored in unit 44 and alarm is activated to provide relevant notifications.

  A connector 11 for inserting an IC chip 43 ′ is installed on the machine body 10, and an electrical circuit of the connector 11 is connected to the control circuit 40, and the IC chip 43 ′, the internal IC chip 43 and the control circuit 40 are connected. It is constituted by the connection matching. The IC chip 43 ′ mainly records biometric features such as a fingerprint and an eyeball as an example of a driver and a car owner. When the vehicle anti-theft device is activated, the motor 50 drives the lock component 20 to an angle at which the handle 70 is clamped (see FIG. 4). Further, the control circuit 40 is connected to the door lock of the vehicle, and when the door is opened, the user inserts the IC chip 43 ′ into the connector 11 as shown in the operation flowchart of FIG. 2B. Then, the image collection component 30 is immediately activated, and an image in the driver's seat direction is collected. After the driver image is collected, it is compared with the ecological characteristics of the original driver recorded on the internal IC chip 43.

  When it matches the compared biometric feature, the motor 50 is activated, and the lock part 20 is removed from the handle 70 so that the vehicle can be operated normally. On the other hand, when not compared with the biometric feature compared, the lock part 20 keeps the state where the handle 70 is sandwiched and the image record of the person sitting in the driver's seat is composed of a flash memory, a copy machine, and a hardware machine. It is stored in the recording unit 44 and the alarm is activated to make a relevant notification.

  Furthermore, the vehicle anti-theft device can record the image of the intruder, and also transmits the image taken by the image collecting component 30 to a receiving facility such as a mobile phone of the car owner or a security organization by a wireless communication method. The car owner or security agency can immediately receive the image of the intruder and the actual state of the door being opened, and can respond immediately.

  The vehicle anti-theft device of the present invention can be instructed to the driver to insert an IC chip or approach an image capturing component in each process by being combined with a voice function. Furthermore, if the independent power source supplied by the rechargeable battery is used as the supply source, the problem that the circuit of the car is broken and the apparatus does not operate is solved.
