Warning device for avoiding secondary traffic accident at night

Abstract

The invention provides a warning device for avoiding a secondary traffic accident at night. The warning device is composed of a laser module, a power adjusting module, a rotary knob and a bracket. The power adjusting module is fixed to the bracket. The rotary knob is installed on the power adjusting module, and the laser module is further installed on the power adjusting module. The warning device has the benefits that warning of the secondary traffic accident at night is achieved through the laser module, the power adjusting module, the rotary knob and the bracket, and occurring of the secondary traffic accident can be effectively reduced; an annular metal ring and an annular metal groove of the laser module are concentrically matched, and the irradiation position of a laser head can be adjusted; and the laser head of the laser module is obliquely installed, the oblique angle is 10-30 degrees, and thus an obstacle caused by a laser beam to a rear vehicle is also avoided meanwhile the rear vehicle is reminded.

Description

technical field [0001] The invention relates to a warning device, in particular to a warning device for avoiding secondary traffic accidents at night, and belongs to the technical field of road safety devices. Background technique [0002] Secondary traffic accidents refer to accidents caused by natural force majeure, the negligence of the rescue party, or the wrong operation of the parties on the basis of the original traffic accidents and other accidents. The secondary traffic accident is the second excitation of the risk factors of an accident, resulting in the expansion and spread of the accident. With the increase of vehicle ownership, the number of cars on the road is increasing day by day. However, this also provides a risk factor for the increase of night traffic. Night traffic accidents are often caused by secondary traffic accidents. Compared with the first accident, the injury is often greater, resulting in more serious personal and property losses, which will gr...

Problems solved by technology

With the increase of vehicle ownership, the number of cars on the road is increasing day by day. However, this also provides a risk factor for the increase of night traffic. Night traffic accidents are often caused by secondary traffic accidents. Compared with the first accident, the injury is often greater, causing more serious personal and property losses, which will greatly increase the difficulty of further rescue work

[0003] At present, a triangular reflective warning sign or a triangular luminous warning sign is generally used to place 50m behind the accident vehicle to remind the vehicles coming from behind. , the role of the warning sign is basically useless
