[0019] In the second invention of the present invention, a method for unlocking a smart electric vehicle lock capable of Bluetooth unlocking and password unlocking is provided, comprising the following steps: S1.

[0020] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use; The instructions for using the smart electric vehicle lock that can be unlocked by Bluetooth and password are as follows: In factory mode, the vehicle is in ownerless state, and the MCU module outputs signals to make both dual-color lamp beads red and breathing. When the user turns the knob switch from the first position to the second position, the second position is the open position, the electric door lock is energized, and the entire vehicle can be started.
[0021] Bluetooth binding operation: When you turn the knob switch five times in succession, it enters the user binding state. Within 10 seconds, use the mobile phone to achieve wireless connection with the vehicle Bluetooth, which means the Bluetooth binding is successful and a record is generated inside the MCU module. Multiple users can be bound at a time. In addition, pressing the knob switch for more than 10 seconds can restore to the factory mode.
[0022] There are two unlocking methods after binding the user: Bluetooth unlocking and password unlocking.
[0023] When in Bluetooth connection state, the central control instrument transmits the signal to the MCU module, and the MCU module outputs a signal to make the two dual-color lamp beads blue together with a breathing effect to inform the customer that Bluetooth is connected. At this time, turn the knob switch, the MCU module receives the signal sent by the first detection module, and the electronic switch module is turned on. The electric door lock is powered on, and the whole vehicle can be started. After power is on, the MCU module makes the two dual-color lamp beads blue together and keep them on.
[0024] This is to prevent the owner from walking within the Bluetooth sensing range with no intention of using the vehicle, but the two-color lamp beads continue to be in a breathing state.
[0025] Then set the following program: If one of the following situations occurs: "When the Bluetooth signal is connected, the first detection module does not recognize the rotation of the knob switch within 30 seconds" or "When the Bluetooth signal is repeatedly disconnected for more than 3 times", the Bluetooth recognition function will become invalid and both dual-color lamp beads will go out. The Bluetooth signal recognition function can only be restored after the micro switch is triggered.
[0026] When the Bluetooth recognition function is disabled, turn the knob switch, and the dual-color lamp turns red. After the knob switch is reset to the first position, the dual-color lamp turns off.
[0027] Comes with factory-set password, the default value is 11; The password setting method is: when there is a Bluetooth input signal, turn the knob switch more than 5 times in 5 seconds, and finally stay in the on position (second position) and maintain the Bluetooth connection state; enter the password setting state.
[0028] The rotation of the knob switch serves as the input for digital change, and the trigger signal of the micro switch serves as confirmation.
[0029] The following is the setting process for setting the password to 86: When there is a Bluetooth input signal, turn the knob switch more than 5 times in 5 seconds, and finally stay in the on position and maintain the Bluetooth connection state; enter the password setting state, at this time the two-color lamp bead on the left goes out, and the two-color lamp bead on the right flashes red, and at the same time, it is transmitted through the one-line protocol. The digital password column on the central control instrument will display the currently entered value. At this time, the unit digit display of the digital password column of the central control instrument is flashing, and the tens digit is displayed as "-", indicating that the unit digit input state has been entered. Turn the knob switch 6 times, and the unit digit display on the central control instrument increases from 0 to 6. Press the knob switch to trigger the micro switch to confirm the unit digit. At this time, the two-color lamp bead on the right stops flashing and turns blue, and the two-color lamp bead on the left flashes red, indicating that the unit digit has been entered and the tens digit has begun to be entered; at the same time, the 6 displayed in the unit digit of the digital password column stops flashing, and the "-" displayed in the tens digit changes to 0 and continues to flash, entering the tens digit input state. Turn the knob switch 8 times, the tens digit display increases from 0 to 8, press the knob switch to trigger the micro switch, confirm the tens digit, then the left two-color lamp stops flashing and turns blue. Both two-color lamps are blue, indicating that the password is entered successfully.
[0030] After the first successful setting, turn on the knob switch within 5 seconds to unlock the electric door lock.
[0031] When Bluetooth is not connected, turn the knob switch for more than 5 times to enter the password input state. At this time, the two-color lamp bead on the left goes out, and the two-color lamp bead on the right flashes red. At the same time, the digital password column on the central control instrument will display the currently entered value through the one-line protocol. At this time, the ones digit display in the digital password column of the central control instrument flashes, and the tens digit displays "-", indicating that the input state of the ones digit has begun. Turn the knob switch 6 times, and the ones digit display of the digital password column increases from 0 to 6. Press the knob switch to trigger the micro switch to confirm the ones digit. At this time, the two-color lamp bead on the right stops flashing and turns to blue, and the two-color lamp bead on the left flashes red, indicating that the ones digit has been entered and the tens digit has begun to be entered; at the same time, the 6 displayed in the ones digit of the digital password column stops flashing, and the "-" displayed in the tens digit changes to 0 and continues to flash, entering the input state of the second digit. Turn the knob switch 8 times, the tens digit display increases from 0 to 8, press the knob switch to trigger the micro switch, confirm the tens digit, and the left two-color lamp stops flashing and turns blue. Both two-color lamps are blue, indicating that the password is entered successfully. Open the knob within 5 seconds after entering the correct password to unlock the electric door.
[0032] If the password input state stays for more than 10 seconds, the password input state will be automatically exited. If the password is entered incorrectly, the two dual-color lamp beads will flash red twice at the same time, and then automatically go out, and (- -) will be displayed on the central control instrument to indicate that the input is wrong. A total of 3 wrong inputs can be made. If the input is wrong three times in a row, the password function will be invalid until the next Bluetooth signal is connected, and the password function will be restored.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
