Problems solved by technology

At this time, if the "triangular warning sign" equipped with the vehicle is lost or damaged, it will have an impact on warning other vehicles to avoid
When the weather conditions are bad, there is strong wind, heavy rain or heavy fog, even if the "triangular warning sign" is placed, the warning effect will be greatly reduced due to the reduction of visibility. greater potential danger

Embodiment Construction

[0018] like figure 1 , in the rear bumper of the car, a holographic projection lamp with long-range projection function is installed;

[0019] The "start" control terminal of the holographic projection lamp is connected with the vehicle control circuit and / or the special switch of the emergency warning sign lamp.

[0020] When the special switch of the emergency warning sign light sends out the command of "activating the emergency warning sign light", the emergency warning sign light is "energized" to light up, and a dynamic three-dimensional light beam visible to the naked eye is output from the rear of the vehicle;

[0021] The light beam is at least 50 meters behind the car, and a three-dimensional red triangle cursor visible to the naked eye is formed in a space 1.5 meters above the ground, suspended in the air, and rotates slowly at a constant speed on the central axis of the triangle; through manual or automatic adjustment The projection angle of the cursor is used to c...

Abstract

The invention discloses a method for projecting a dynamic warning cursor behind a vehicle. The method comprises the steps that a holographic image projection lamp with a long-range projection functionis adopted, a macroscopic three-dimensional light beam is output on the tail portion of the vehicle, the three-dimensional warning cursor is formed in the height space at the specified distance behind the vehicle, and formation of an emergency warning mark behind the vehicle is triggered through an emergency warning mark lamp switch. In this way, the process that when parking the vehicle due to afault, a driver needs to place a triangle warning board behind the vehicle is omitted, and therefore, the potential danger coefficient is reduced. Besides, the emergency warning mark can be generatedfor the first time so as to remind other drivers of paying attention to avoid the vehicle as soon as possible, and the potential danger coefficient is further reduced.

Description

technical field [0001] The invention belongs to the field of automobile signal display devices, and in particular relates to a method for displaying a three-dimensional warning signal in the space behind the automobile. Background technique [0002] According to Article 52 of the "Road Traffic Safety Law of the People's Republic of China", when a motor vehicle breaks down on the road and needs to be stopped to remove the fault, the driver should immediately turn on the flashing lights of the danger alarm and move the motor vehicle to a place that does not hinder the traffic. If it is difficult to move, the danger alarm flashing lights should be continuously turned on, and warning signs should be set up in the direction of the approaching vehicle to expand the warning distance; the position of placing the "triangular warning sign" should be 150 meters away from the approaching direction of the accident vehicle , to warn other vehicles. According to traffic regulations, any m...
