The principle of the utility model: the anti-theft lock is arranged on the front axle of the electric vehicle, the anti-theft lock is connected to the micro-controller through the wire, the micro-controller is connected to the alarm circuit module, the alarm circuit module is connected to the wireless signal transmitting module, and the wireless signal transmitting module is connected to the car owner through the signal station The terminal, the microcontroller and the alarm circuit module are arranged at the bottom of the vehicle seat, the lithium battery supplies power to the microcontroller and the keyboard, the information input by the keyboard is displayed on the LED display, and the keyboard and the LED display are arranged on the handlebar. the

As shown in Figure 2, the microcontroller 2 of the utility model embodiment also includes: electronic coded lock module 2-1, detection circuit module 2-2, alarm self-locking module 2-3, timing unlocking circuit module 2-4, Manual unlocking circuit module 2-5, oscillation circuit module 2-6, alarm 2-7;

The electronic combination lock module 2-1 is connected, the detection circuit module 2-2, the detection circuit module 2-2 is connected to the alarm self-locking module 2-3, and the alarm self-locking module 2-3 is connected to the timing unlocking circuit module 2-4, the oscillation circuit module 2-6 and the manual unlocking circuit module 2-5, the oscillation circuit module 2-6 is connected to the alarm 2-7;

The alarm circuit module adopts a buzzer. When the password is entered incorrectly three times or abnormal unlocking is detected, the buzzer starts to sound an alarm. the

The wireless signal transmitting module adopts a ready-made radio transceiver module with simple functional components and low cost. When the detection circuit finds that the password has been entered incorrectly for three times or the lock is opened abnormally, the loudspeaker will sound an alarm and send a signal to the owner through the radio transceiver module. the

The keyboard of the utility model adopts a matrix keyboard, which are respectively 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, *, #, DEL, CLR, ENTER, MODIFY; the initial password is "123456789"; When entering the password, the LED display will display "*", when the password is entered and press the ENTER key, compare the input password with the set password, if the password is correct, the LED display will display "PASS" to prompt the lock to open; If the password is incorrect, the LED display will display a prompt "ERROR", if the input is incorrect for 3 consecutive times, an alarm will sound and the keyboard will be locked at the same time;

After entering the correct password, when the modify key is pressed, the LED display circuit will display "old" and prompt "input the old password". At this time, if the correct old password is entered, the display circuit will prompt to enter the new password. After entering the new password, The display circuit will prompt again "Enter the new password again." If the two input passwords are inconsistent, the password modification will fail, and if they are consistent, the password modification will succeed. In the process of modifying the password, if the old password input at the beginning is wrong, the display circuit will display a prompt, and the system will return to the beginning at the same time. the

If the new password entered at the time of "re-enter the new password" is inconsistent with the previous one, it will return to the beginning of the system. After changing the password, the system will automatically clear and lock. To unlock again, you need to enter the correct password. In the system, the DEL key is used to backspace, and the CLR key is used to clear the screen. Press CLR to delete the password just entered, and then enter it again. In order to prevent malicious attempts, the system will send out an alarm sound if the wrong password is entered 3 times in a row, and lock the keyboard, which can improve the safety factor of the system and also protect the normal use of legitimate users. And there is also a notification to the owner through the sending and receiving of radio signals to achieve a better anti-theft effect. the

The lockset of the utility model is placed on the support frame of the front wheel of the electric vehicle, and there are two wires connected with the rest of the parts, one of which is connected with the 4×4 matrix keyboard made by the microcontroller placed in front of the handlebar. It is used to receive the input of the password, and display the input status of the password and the feedback of the information on the LED display circuit; the other one is connected to the external power supply under the seat cushion of the electric vehicle, so as to charge the storage battery of the lock while charging the electric vehicle. The adequacy of the power of the intelligent anti-theft system is guaranteed. the

When someone enters the password correctly, the lock will open normally; when someone enters the password incorrectly three times (may be a thief), the speaker of the alarm will sound an alarm, oscillate the circuit and emit a radio signal to notify the owner. When the detection circuit finds that the lock is not normally opened (for example: a thief picks the lock, etc.), the speaker of the alarm will sound an alarm, and the oscillator circuit will emit a radio signal to notify the owner. In order to prevent the alarm sound from affecting others, the alarm sound will be automatically canceled after 3 minutes; within these 3 minutes, the owner can also manually cancel the alarm sound through the keyboard. the
