a parking sign

Abstract

The invention relates to a parking warning sign, comprising: an installation substrate, on which a warning pattern area (1), a power supply module (2) and a control module (3), the warning pattern area (1), the area is provided with At least one warning pattern, and several LEDs are arranged along the outline of the warning pattern, the power supply module (2) supplies power to each LED in the warning pattern area (1), and the control module (3) controls the warning pattern area (1) The lighting and extinguishing of each LED in the power supply module (2) provides charging management. The parking warning sign of the present invention has a simple structure, is convenient to use, takes into account volume and weight, has good wind and rain resistance, has multiple warning modes, and has a visible distance of more than 200 meters at night, and has good reliability.

Description

technical field [0001] The invention relates to a parking warning device, in particular to a parking warning sign. Background technique [0002] When the vehicle encounters a sudden breakdown and stops for maintenance, or when the vehicle has an accident, it is necessary to place a parking warning device at a certain distance behind the vehicle, so as to remind other normal vehicles to avoid traffic accidents in time. [0003] Most of the existing parking warning devices are automobile warning triangles, which are passive reflective bodies made of plastic reflective materials. Utilizing the retroreflective performance of the automobile warning triangles, other vehicles can be reminded to avoid secondary accidents. [0004] According to the "Road Traffic Safety Law of the People's Republic of China", on regular roads, when a breakdown occurs or a traffic accident occurs, a warning triangle should be placed 50 meters to 100 meters behind the vehicle; Set up warning signs 150 ...

AI Technical Summary

Problems solved by technology

[0007] 1. The reflective effect is not good in daytime or foggy days, and the warning effect is relatively poor;

[0008] 2. The small size makes it difficult to be detected. Once the distance from the vehicle is not far enough, it is difficult to play a warning role;

[0009] 3. Light weight leads to poor wind resistance
