DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Figures 1 to 3 Shown is an embodiment of the utility model.

[0019] Embodiment 1:

When the user brakes, the signal acquisition module 1 collects the brake light on and sends an instruction to the signal receiving module 3. After receiving the instruction, the signal receiving module 3 controls the driving light signal transmitting module 2 to project the visible light signal 18 toward the back of the user, so that the brake signal light can be displayed with the help of the user's broad back, so that the vehicles behind the user can clearly see the brake signal light, which is convenient for the following vehicles to make corresponding reactions and avoid some accidents. The driving light signal transmitting module 2 only emits visible light toward the back of the user, and will not cause light pollution to the opposite vehicles and adjacent vehicles, affecting the driving of these vehicles. The utility model does not modify the original light of the motorcycle 17, and is easy to use.

[0021] The signal acquisition module 1 includes an electrically connected acquisition unit 4 and an infrared transmitter 5, the signal receiving module 3 is an infrared receiver, the infrared transmitter 5 is aimed at the infrared receiver, and the acquisition unit 4 is used to collect the taillight on / off signal. The acquisition unit 4 can be incorporated into the power line of the taillight of the locomotive 17. When braking, the power line of the taillight of the locomotive 17 is energized, so that the acquisition unit 4 can be directly energized to energize the infrared transmitter 5, so that the infrared transmitter 5 will emit an infrared signal 19 toward the infrared receiver. The acquisition unit 4 can also use a photoresistor, which is installed on the local taillight of the locomotive 17 through a patch, and the change in the light intensity of the taillight of the locomotive 17 is used to control the infrared transmitter 5 to emit an infrared signal 19. A photoresistor is a resistor made by using the photoelectric effect of a semiconductor, and its resistance value changes with the intensity of the incident light; when the incident light is strong, the resistance decreases, and when the incident light is weak, the resistance increases. Photoresistors are generally used for light measurement, light control, and photoelectric conversion (converting light changes into electrical changes). Usually, photoresistors are made into thin-sheet structures to absorb more light energy. When it is irradiated by light, electron-hole pairs are excited in the semiconductor sheet (photosensitive layer) to participate in the conduction, thereby enhancing the current in the circuit. In addition to using the infrared transmitter 5 and the infrared receiver for communication, multiple communication methods such as Bluetooth communication or wired communication can also be used.
