Abstract: A rear approaching vehicle detecting and warning device comprises a detecting device installed at an appropriate position behind a motorbike body, a signal processing module, and a riding safety component capable of being assembled on handlebars of the motorbike. The detecting device is provided with a sensing module, a control circuit, and a signal transmitting module. The sensing module senses a vehicle approaching around to generate a detection signal. The signal transmitting module receives the detection signal through the control circuit and then transmits the detection signal. The signal processing module is used for receiving and processing the detection signal transmitted by the signal transmitting module to generate a warning signal. The riding safety component is provided with a light module and electrically connected to the signal processing module. The riding safety component is used for receiving the warning signal to display on the light module.

Abstract: A blind spot detecting and warning device suitable for two-wheeled mobile device comprises a detecting device installed at a first position behind a user and a warning device installed at a second position that is in front of the user and can be seen by the user. The detecting device is provided with a sensing module, a control circuit and a signal transmitting module. When the sensing module senses a vehicle is approaching around, the sensing module generates a detection signal. The signal transmitting module receives the detection signal through the control circuit and then transmits the detection signal. The warning device is provided with a signal processing module and a warning module, wherein the signal processing module is used for receiving the detection signal transmitted by the signal transmitting module, and the detection signal drives the warning module to generate a warning.
