  • Bicycle safety system
    Patent number: 12291299
    Abstract: A safety system for bicycles includes a radar, a controller, and a warning apparatus, which includes a tube, a vibrating motor, and an impact sounder. The vibrating motor includes a rotary shaft and an eccentric block. The impact sounder includes an elastic member and an impact block. The elastic member includes a first end fixed to the inner wall of the tube and a second end connected to the impact block. When the controller decides to issue a warning based on a radar signal, it outputs a control signal to drive the rotary shaft to rotate. The rotation of the rotary shaft drives the eccentric block to rotate and vibrate, and the eccentric block strikes the impact sounder to make the impact block hit the inner wall and thus generate an impact force and emit a sound. The warning apparatus simultaneously provides the bicycle rider with vibrating, impacting, and audible warning.
