Triangular warning board

Abstract

The invention discloses a triangular warning board. The triangular warning board comprises three board bodies which are mutually connected to form a triangle, wherein light reflection layers are arranged on the board bodies; connecting blocks are arranged in the connecting positions of the board bodies; rotational structures are arranged between two ends of each board body and the connecting blocks, and the rotational structures at two ends of the same board body are coaxial; the connecting blocks are connected with a supporting rod, and a fixing block is connected with the lower part of the supporting rod; a plurality of first LED lamps are arranged on the board bodies, and a plurality of second LED lamps are arranged on the side walls of the board bodies; and control switches are arranged on the rotational structures. The triangular warning board can be prevented from being blown away by wind, the possibility that the triangular warning board is blown to be broken is reduced, and a better warning effect can be realized.

Description

technical field [0001] The invention relates to a warning device, in particular to a triangular warning board, which is used for placing a warning board behind the vehicle when the vehicle fails. Background technique [0002] The car warning triangle is a passive reflective body made of plastic reflective material. When the driver encounters a sudden breakdown on the road and stops for maintenance or accidents, he can use the reflective performance of the warning triangle to remind other vehicles to avoid , to avoid secondary accidents. Generally speaking, when a driver finds a triangle warning sign ahead, he needs to go through a process of discovering, clearly seeing the warning signal ahead, taking measures to brake, slow down, and avoid. Taking a car traveling at a speed of 100 kilometers per hour as an example, generally speaking, it needs at least 10.8 seconds of reaction time or a distance of at least 350 meters. This requires the warning triangle to be highly refle...

AI Technical Summary

Problems solved by technology

The reflection of the warning triangle is more conspicuous at night, but inconspicuous during the day, so the warning effect is relatively poor

[0003] The general warning triangle is made of plastic and is relatively light in weight, so it is easy to be blown away in windy weather

After the warning triangle is blown away, the rear vehicle can easily hit the vehicle parked on the roadside for maintenance and cause a secondary accident. Therefore, people will set up a weighted block under the warning triangle to prevent the warning triangle from being blown away. However, the warning triangle supported by plastic The strength of the card is very low, so it can be easily broken by the wind
