Description

An intelligent mechanical lock

technical field

The utility model relates to a mechanical lock with high safety, in particular to an intelligent mechanical lock.

Background technique

Locks were born almost at the same time as private ownership. A must-have for protecting intimate items from ancient times to the present. Nowadays, some manufacturers of locks have not made any progress in the anti-theft performance of their own locks. Not as good as the oldest, simple padlock. From the development history of locks, in order to prevent the opening of the master key, the manufacturing process of the lock will be particularly complicated, and the manufacturing cost will increase by more than ten times. At the same time, its anti-violent performance will also be greatly reduced. The industry has been plagued by this problem for a long time. And no matter the key that the current lock needs to match is on the problem of anti-lost or anti-theft, it also threatens the safety of the valuables protected.

Contents of the invention

The purpose of this utility model is to provide an intelligent mechanical lock. The intelligent mechanical lock does not need to wear a key, and only needs a smart phone equipped with an application program to realize the function of opening and closing the lock.

The utility model is achieved in this way, an intelligent mechanical lock, which mainly includes a stepping motor, a screw, an integrated circuit module, a bluetooth module, a slider, a lock bolt and a lock body; it is characterized in that the bluetooth module is fixed on the lock Inside the body, the integrated circuit module is connected with the serial data line, the integrated circuit module is connected with the stepping motor through the stepping motor drive line, the stepping motor is fixed on the lock bolt, and the slider is connected with the screw rod.

The appearance of the mechanical lock described in the utility model can be rectangular or square.

The integrated circuit module of the utility model has a built-in single-chip microcomputer.

The working principle of the utility model is: when the bluetooth module inside the lock receives the correct instruction, the information will pass through the serial data line, the integrated circuit module, the stepper motor drive line in turn, and finally to the stepper motor, and the stepper motor will receive the correct instructions. After the command, if the unlocking command is accepted, the stepping motor will reverse, and since it acts as a slider to fix the lock body, the lock bolt will move in parallel under the action of the screw to extend the lock body; if the lock command is accepted, the stepping motor will The motor rotates forward, and since it acts as a slider to fix the lock body, the lock bolt moves in parallel under the action of the screw rod, retracts inward, and enters the lock body.

The electronic lock of the utility model can have the function of setting a password by itself, and the password is stored in the EEPROM inside the single-chip microcomputer, so that the password will not be lost when the power is turned off. And the lock will not open even if the power is off. To open this electronic lock, you need to know the Bluetooth address of the electronic lock, the Bluetooth pairing password, and the password to open the door (the password is case-sensitive, and you can use punctuation marks, numbers, and special characters), all of which make it almost impossible to unlock the lock .

The effect of the utility model is: the structure of the mechanical lock is relatively simple, and the degree of security is high; the electronic lock can have the function of setting a password by itself, and there is no need to wear a key, and only one smart phone is needed to unlock the lock.

Detailed ways

The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. All similar structures and similar changes of the utility model should be included in the protection of the utility model. scope.

As shown in Figure 1, the utility model works and implements like this, a kind of intelligent mechanical lock, it mainly comprises stepper motor 1, screw mandrel 2, integrated circuit module 3, bluetooth module 4, slide block 5, lock bolt 8 and the lock body 9; it is characterized in that: the bluetooth module 4 is fixed in the lock body 9, and is connected to the integrated circuit module 4 through the serial data line 7, and the integrated circuit module 4 is connected to the stepper motor 1 through the stepper motor drive line 6, and the step The feeding motor 1 is fixed on the lock bolt 8, and is connected with the slider 5 through the screw mandrel 2.

The installation and use of the intelligent mechanical lock:

Step 1: Install the electronic lock inside the door, and plug the power adapter of the electronic lock into the socket;

Step 2: Take out the mobile phone and download the "Bluetooth serial port" software, open the software and it will automatically turn on Bluetooth, click "Connect" and the phone will search for Bluetooth ("HC-05" Bluetooth name change, please see "Bluetooth name modification"), and then Enter the pairing password "1234" (this password can be modified, please refer to "Modification of the pairing password.") After connecting, you can see "Please input your password:" (the password to open the Bluetooth electronic lock can be modified by the user, refer to Bluetooth for details. Open the electronic lock and modify the password) At this time, the user can enter the password. If the password is correct, the mobile phone will display "Wellcome home" and open the electronic lock; if the password is incorrect, the mobile phone will display "Your password was wrong".

Step 3: If the door has been opened, the mobile phone will display: "Please input command:" At this time, the user can enter the "Close" command, and the Bluetooth electronic lock will be locked.

The bluetooth name modification: Connect the USB to TTL data cable to the serial data cable (7) in the attached drawing of the instruction manual, open the USB debugging assistant on the computer, and input "AT+NAME<name>" to modify it to what the user wants The name "name".

The Bluetooth pairing password modification: Connect the USB to TTL data cable to the serial data cable (7) in the attached drawing of the instruction manual, open the USB debugging assistant on the computer, and enter "AT+PIN<password>" to modify it to the user's desired password. The name "password". the

The Bluetooth electronic lock opening password modification: only when the lock is open, the mobile phone will display: "Please input command:" At this time, the user can enter: "Change", and then the mobile phone will display: "Please input your new password:" This Then the user can freely enter the password he wants. If the change is successful, the phone will display: "Your password was Change", if not, the phone will display "Please try again".
