car parking warning sign

Abstract

The invention discloses an automobile parking warning board. The 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, a fixing block is connected with the lower part of the supporting rod, and a supporting frame is arranged on the fixing block; the supporting rod is rotationally connected with the supporting frame; a weight is arranged at the lower end of the supporting rod, and the mass of the weight is larger than that of the warning board above the connecting position of the supporting rod and the supporting frame. With the adoption of the structure, the triangular warning board has a better warning effect; and the board bodies constituting the triangular warning board can rotate when the triangular warning board with the structure is blown by wind, the stressed area of the triangular warning board is reduced through rotation, accordingly, stress suffered by the triangular warning board due to wind blowing is reduced, and the possibility that the triangular warning board is blown to be broken is reduced.

Description

technical field [0001] The invention relates to a warning device, in particular to a car parking warning sign, which is used to place a warning sign behind the vehicle when the vehicle breaks down. 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 ref...

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
