Background

With the rapid development of social economy and the improvement of the living standard of people, the automobile industry develops vigorously. With the increasing popularity of automobiles, automobiles have become an integral part of many people's daily lives.

However, as the number of cars traveling on a road increases, various traffic accidents frequently occur. Especially, people often pay attention to traffic safety during driving, but often loose vigilance when parking and getting off the vehicle. People can not clearly see whether objects are close to the roadside parking equipment or not due to neglect of surrounding road conditions or angle limitation when the roadside parking equipment is ready to get off the vehicle, or when the objects in an emergency approach the vehicle, collision accidents are easy to happen.

The warning board is the conventional emergency equipment on the car, and current car warning board outward appearance generally is the triangle-shaped state, has reflective material on the triangle-shaped warning board, utilizes reflective property, reminds other vehicles to notice to dodge to avoid taking place the accident. However, the warning board is small in size and not obvious when placed on the ground, particularly in a road turning part, a low triangular warning board placed on the ground is easily shielded by obstacles such as grass, stones and the like on the roadside, and a driver can not find the triangular warning board in time due to the fact that a vision blind area is generated by shielding of a vehicle head when passing by, so that the warning board cannot effectively play a role; the warning board is light in weight and easy to blow down by wind, so that the passing vehicles cannot be found in time to cause traffic accidents.
