Description

A vehicle warning triangle stability performance test device

Technical Field

The invention relates to the technical field of automobile parts detection, and in particular to a stability performance test device for a vehicle warning triangle.

Background Art

The warning triangle, also known as the warning triangle, is a passive reflector made of plastic reflective material. It mainly serves as a reminder and warning. When the owner encounters a sudden failure or accident on the road, the owner can use the reflective performance of the warning triangle to remind other vehicles to avoid it to avoid a secondary accident. On conventional roads, when a failure or traffic accident occurs, the warning triangle should be set 50 to 100 meters behind the car; on highways, warning signs should be set 150 meters behind the car. If it encounters rainy and foggy weather, the distance must be increased to 200 meters. However, the warning triangle placed on the road is easily blown down by the wind, especially on highways. The warning triangle is easily blown down by the wind generated by a fast-moving car on one side, causing the warning triangle to fall and fail to play its due warning role. There is a great safety risk. Therefore, it is necessary to test the stability of the warning triangle. At present, there is still no test device that can comprehensively test the stability of the warning triangle.
