Description

Door lock device using fingerprint

The present invention relates to a door lock device using a fingerprint, and in particular, a fingerprint detection sensor is mounted on a general door lock system, and a drive for releasing the door lock device according to a drive signal of a controller and a controller for analyzing a fingerprint detected through the fingerprint detection sensor. The present invention relates to a door lock device using a fingerprint having an effect of solving an inconvenience of having to carry a vehicle key at all times by configuring the motor unit.

In general, the door of the vehicle is applied to the vehicle key and the radio control key for starting at the same time is mainly used as the door lock and release device.

Referring to the drawings with reference to Figure 1, the battery 10 for supplying power to the system; A wired adjustment key 20 mounted inside the handle and controlling the door lock by wire; A wireless adjustment key 30 connected to the vehicle key and controlling the door lock by wireless adjustment by microwave waves; A switching switch (21) for designating lock and unlock states by switching the switch according to the operation of the wired adjustment key (20); Analog digital conversion unit 41 for digitally switching the input of the radio control key 30, and relays 42-1 and 42 for connecting the power of the main circuit with a weak signal flow through the digital conversion unit 41. -2), a door lock operation switch 43-1 for switching the door according to the operation of the relay 42-1 to lock the door by forward rotation of the motor, and switching according to the operation of the relay 42-2. A microprocessor 40 including a door unlock operation switch 43-2 for rotating the motor to reverse the motor; The door lock actuator 50 provides a rotational force of forward rotation or reverse rotation according to the contact point of the switch embedded in the microprocessor 40.

In the door lock system using a general key system configured as described above, if the door lock is controlled through a wire after the vehicle is turned on in the vehicle, the changeover switch 21 for switching the door to the locked and unlocked state contacts the contact as the driver intends. It is possible by turning on and off the direction of the actuator 50.

On the other hand, when the mode of the radio control key 30 is operated to control the door lock state by radio, this signal is input to the microprocessor 40 in the form of a microwave wave in a constant frequency form. Then, when the microprocessor 40 has designated the door lock after digital conversion, the relay 42-1 is operated to connect the main power supply 10 to the actuator 50 to rotate the motor forward to lock the door. When the unlock is specified, the door may be unlocked by operating the relay 42-2 corresponding thereto to connect the main power supply 10 to the actuator 50 to reverse the motor.

Therefore, the driver can maintain the door in a desired state by using the wired adjustment key and the wireless adjustment key.

However, when using a door lock system using such a key, since the key is basically carried in the state of carrying a key, there is a problem in that the vehicle door itself cannot be opened if the key is left in the car or the key is lost. In addition, because the key can be duplicated, there is a risk that other people may lose the car.

Accordingly, the present invention has been made to solve the above problem by providing a door lock device using a fingerprint which is a kind of means for independently recognizing a person.

2 is a block diagram of a door lock device using the present invention fingerprint.

Explanation of symbols for the main parts of the drawings

10: Battery 20: Wired Control Key

30: radio control key 40: microprocessor

60: fingerprint sensor 70: controller

80: actuator

As a means for achieving the above object,

The present invention comprises a controller equipped with a fingerprint sensor in a general door lock system, a controller for analyzing a fingerprint detected through the fingerprint sensor, and a drive motor unit for releasing the door lock device according to a drive signal of the controller.

Hereinafter, described in detail with reference to the drawings.

2 is a block diagram of the door lock device using the fingerprint of the present invention, which is installed in the door handle part and scans a beam to detect a fingerprint and a fingerprint sensor 60, and receives the information from the fingerprint sensor 60 in advance And a controller 70 for comparing and analyzing the set fingerprint data, and an actuator 80 having a connection connector and an operation mode to lock or unlock the door according to the output control signal of the controller.

According to the present invention configured as described above, when a hand is put on the door handle part to open the door, the thumb is brought to the position of the fingerprint sensor 60. Therefore, when the fingerprint sensor 60 scans a beam and outputs the scanned information to the controller 70, the controller 70 compares and compares the previously input data with each other. The actuator 80 is driven to open the door.

At this time, if another person grabs the door handle for theft of the vehicle, the controller 70 does not open the door because the data transmitted from the fingerprint sensor 60 does not match the previously input information. In addition, if more than three times wrong, it can be determined that the attempt to theft and generate an alarm sound.

Thus, the driver can safely manage the vehicle and have a non-mechanical electronic device to extend the life of the mechanisms that constitute the door.

As described above, the present invention has the effect of solving the inconvenience of having to carry the vehicle key at all times according to the conventional mechanical configuration by stealing the vehicle door lock control system by fingerprint recognition.

The present invention has been made to solve the inconvenience of locking and releasing the door with a vehicle key, and an object of the present invention is to allow the door to be opened and closed only when the fingerprint is matched with a set fingerprint.
