[0008] The backend server is used to send mode configuration to the device to realize the switching of the taillight between mode 1 and mode 2;

[0009] The mode button is used to directly switch the taillight between mode 1 and mode 2;

[0010] The control module has a Bluetooth key function, and the user can open and close the Bluetooth key through the APP; when the Bluetooth key function is turned on, when the Bluetooth connection between the APP and the device is disconnected, the device switches from mode one to mode two, and when the APP is connected to the device's Bluetooth and the Bluetooth signal strength is greater than a certain value, the device switches from mode two to mode one; when the APP is connected to the device's Bluetooth and the Bluetooth signal strength is lower than a certain value, the device switches from mode one to mode two.

[0015] The expression button is connected to the control module and is used to set the display expression or content of the bicycle taillight.

[0016] As a further improvement of the present invention, when the mode button is short pressed, it is displayed that the current working mode of the taillight is mode 1 or mode 2, and when it is long pressed, it is switched between mode 1 and mode 2.

[0017] As a further improvement of the present invention,

[0022] Establish a connection between the APP and the backend server, and select the working mode of the taillight through the APP application interface, where the working mode is mode 1 or mode 2; send the selected working mode to the control mode of the device, and then control the taillight to switch between mode 1 and mode 2;

[0023] 2) Switch the bicycle taillight mode based on the background:

[0024] If the APP is not currently connected to the device via Bluetooth, the APP will send the configuration information to the backend, which will then send the mode configuration to the device, and control the taillights based on the configured mode to switch between mode 1 and mode 2;

[0025] 3) Switching bicycle taillight modes based on mode button:

[0029] As a further improvement of the present invention, the switching of bicycle taillight modes based on a Bluetooth key specifically includes:

[0030] 1) When the taillight is in Mode 1:

[0031] Determine whether the Bluetooth key function is turned on;

[0032] If the Bluetooth key function is not turned on, the taillight works in Mode 1 and does not switch;

[0033] If the Bluetooth key function is turned on, determine whether the Bluetooth connection between the APP and the device is disconnected;

[0034] If the Bluetooth connection is disconnected, the taillight switches from Mode 1 to Mode 2;

[0035] If the Bluetooth connection is not disconnected, it is determined that the Bluetooth signal strength is lower than a certain value (minimum threshold);

[0036] If the Bluetooth signal strength is lower than a certain value, the taillight switches from mode 1 to mode 2;

[0037] If the Bluetooth signal strength is not lower than a certain value, the taillight works in mode 1 without switching;

[0038] 2) When the taillight is in Mode 2:

[0039] Determine whether the Bluetooth key function is turned on;

[0040] If the Bluetooth key function is not turned on, the taillight works in Mode 2 and does not switch;

[0041] If the Bluetooth key function is turned on, determine whether the APP is connected to the device through Bluetooth;

[0042] If Bluetooth is connected and the Bluetooth signal strength is greater than a certain value (maximum threshold), the taillight switches from mode 2 to mode 1;

[0043] If the Bluetooth is not connected, or if the Bluetooth is connected but the Bluetooth signal strength is not greater than a certain value, the taillight works in mode 2 without switching;

[0044] Among them, the mode switching of the above-mentioned taillight is operated by the APP, that is, the APP determines whether the Bluetooth is connected and compares the signal strength with the set value.

[0045] As a further improvement of the present invention, it is characterized in that

[0046] Mode 1 is normal mode, the taillight is on, and the dynamic reporting cycle is T1;

[0047] Mode 2 is sentinel mode, the taillights are turned off, and the dynamic reporting period is T2, which is less than T1.

[0077] The present invention also discloses a bicycle taillight mode switching method based on the bicycle taillight system, comprising:

[0078] 1) Switching bicycle taillight modes based on APP:

[0079] Establish a connection between the APP and the backend server, and select the working mode of the taillight through the APP application interface, where the working mode is mode 1 or mode 2; send the selected working mode to the control mode of the device, and then control the taillight to switch between mode 1 and mode 2; here, when the APP directly controls the device to switch modes, the APP does not need to establish a connection with the backend;

[0080] 2) Switch the bicycle taillight mode based on the background:

When the Bluetooth connection between the APP and the device is disconnected, the device switches from mode 1 to mode 2; when the APP is connected to the device's Bluetooth and the Bluetooth signal strength is greater than a certain value, the device switches from mode 2 to mode 1; when the APP is connected to the device's Bluetooth and the Bluetooth signal strength is lower than a certain value, the device switches from mode 1 to mode 2.

[0086] Among them, the bicycle taillight mode switching is realized based on the Bluetooth key, specifically including:

[0087] like Figure 4 As shown in the figure, when the working mode of the current taillight is normal mode:

[0088] Determine whether the Bluetooth key function is turned on;

[0089] If the Bluetooth key function is not turned on, the taillights will work in normal mode without switching;

[0090] If the Bluetooth key function is turned on, determine whether the Bluetooth connection between the APP and the device is disconnected;

[0091] If the Bluetooth connection is disconnected, the taillight switches from normal mode to sentry mode;

[0092] If the Bluetooth connection is not disconnected, it is determined that the Bluetooth signal strength is lower than a certain value;

[0093] If the Bluetooth signal strength is lower than a certain value, the taillight switches from mode 1 to mode 2;

[0094] If the Bluetooth signal strength is not lower than a certain value, the taillight works in mode 1 without switching.

[0095] like Figure 5 As shown in the figure, when the working mode of the front tail light is sentry mode:

[0096] Determine whether the Bluetooth key function is turned on;

[0097] If the Bluetooth key function is not turned on, the taillight works in sentinel mode and does not switch;

[0098] If the Bluetooth key function is turned on, determine whether the APP is connected to the device through Bluetooth;

[0099] If Bluetooth is connected and the Bluetooth signal strength is greater than a certain value, the taillight switches from sentinel mode to normal mode;

[0100] If the Bluetooth is not connected, or if the Bluetooth is connected but the Bluetooth signal strength is not greater than a certain value, the taillight works in the sentinel mode and does not switch.

[0103] After the Bluetooth key function is turned on, if the user actively disconnects the Bluetooth or the user is a certain distance away from the vehicle so that the Bluetooth signal strength is lower than a certain value, the present invention automatically switches from the normal mode to the sentinel mode to achieve automatic control of the taillights, that is, the taillights are automatically turned off after the user leaves the vehicle.

[0104] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
