Triangular warning indicator

Abstract

The embodiment of the invention provides a triangular warning indicator for a vehicle. The indicator comprises a holding mechanism mounted at the tail of the vehicle, and a warning ball held by the holding mechanism, the holding mechanism is controlled to release the warning ball to enable the warning ball to be separated from the tail of the vehicle to the ground, the warning ball moves on the ground in a remote control or autonomous mode, and a floating triangular warning image is displayed to a rear coming vehicle in a projection mode after the warning ball reaches a designated place. By the adoption of the warning signal device, rear coming vehicles can be prompted more conveniently and remarkably, a special warning plate is not needed, the size is small, the warning signal device is safe to the rear coming vehicles, and the warning distance is controllable and adjustable.

Description

technical field [0001] The invention belongs to the field of general vehicle signals, in particular to a triangular warning device for vehicles. Background technique [0002] When the vehicle breaks down or has an accident, the driver of the vehicle needs to place a tripod behind the vehicle to warn other vehicles. However, the driver is prone to danger when placing the tripod. This danger generally comes from the impact of unconscious vehicles in the rear (because the rear vehicle cannot know in advance that the vehicle in front has an accident, so it cannot be avoided in time), resulting in road accidents. secondary accident. [0003] In order to solve this problem, there have been some designs in the prior art that place warning triangles on remote-controlled mobile cars, such as Beijing Institute of Technology's intelligent warning triangles for vehicles based on mobile terminal interaction (see patent document CN106218500A), The triangle warning device of Daimler AG (...

AI Technical Summary

Problems solved by technology

[0004] The above designs can avoid the potential safety hazards caused by the artificial placement of the tripod, but the mobile car-mounted warning triangle is large in size. If the car coming from behind does not evade or slow down in time, it will even increase the collision damage of the car coming from behind. ; and the launch type warning triangle has a limited range, which is far less than the distance stipulated by traffic regulations. If a larger launch speed is used in order to increase the range, the launch itself is dangerous, and the fired warning triangle needs to be It is designed as a structure that can be retracted / deployed, and it is difficult to ensure accurate deployment and stability when landing, which affects the warning effect
