Description
Technical Field
The invention belongs to the field of general vehicle signals, and particularly relates to a triangular warning indicator for a vehicle.
Background
When a vehicle breaks down or has an accident, a driver of the vehicle needs to put a tripod behind the vehicle to warn other vehicles. However, when the tripod is placed, a driver is prone to danger, which generally comes from the collision of an unconscious vehicle behind the vehicle (since the vehicle behind cannot know in advance that an accident occurs in the vehicle in front, so that timely avoidance cannot be performed), thereby causing a secondary accident on the road.
To solve this problem, some designs have appeared in the prior art, such as intelligent triangle warning board for vehicles based on mobile terminal interaction (see patent document CN106218500A) of beijing university of science and technology, and triangle warning device of thomlike corporation (see patent document CN 110435537A). There are also some designs of rear launch/throw triangular warning signs such as those disclosed in CN110329145A and CN 106740454A.
The design can avoid potential safety hazards caused by manually placing the tripod, but the triangular warning board arranged on the moving vehicle has larger volume, and collision damage of a vehicle coming from the rear can be increased even if the vehicle coming from the rear is not avoided or decelerated in time; the emission type triangular warning board has limited range and can not reach the distance specified by traffic regulations, if a larger emission speed is used for increasing the range, the emission is dangerous, and the emitted triangular warning board needs to be designed into a structure capable of being contracted/expanded, so that the emitted triangular warning board is difficult to ensure to be accurately expanded and stable when falling to the ground, and the warning effect is influenced.
