Description

Portable vehicle-mounted triangular warning board capable of being unfolded through one key

Technical Field

The utility model discloses portable on-vehicle triangle warning sign that a key expandes relates to the warning sign field of vehicle roadside berth back guarantee safety.

Background

The vehicle-mounted triangular warning board is a passive reflector for warning other drivers after a vehicle stops at a roadside due to a fault, and is formed by splicing plastic sheets stuck with a reflective material. When the vehicle is in a sudden failure in the driving process and needs to be parked and overhauled at the roadside, in order to prevent a secondary traffic accident caused by the fact that the vehicle is not timely avoided when the vehicle is driven from the rear, the warning board needs to be placed 50 meters to 150 meters behind the vehicle as soon as possible. For the driving environment with low visibility, such as night and heavy fog weather, the self-reflecting warning effect of the warning board is poor. It is difficult to ensure that the rear vehicle can realize emergency braking under the conditions of high speed and short distance. Data verification shows that an automobile with the speed of 100 kilometers per hour can be safely parked only by a braking distance of at least 350 meters. Therefore, the vehicle-mounted triangular warning board is required to have a remote warning function, and sufficient reaction time is provided for a driver.

The current general on-vehicle triangle warning sign is mostly concatenation formula and console mode. When the triangular warning board is used, all parts of the triangular warning board need to be unfolded and fastened, and a complex assembly process takes precious rush repair time. The visual field of the driver is narrowed during high-speed running, so that the floor type triangular warning board is difficult to be found by the driver in time, and the optimal braking time is missed. The height and the unfolding speed of the triangular warning board are improved, the possibility of secondary accidents is reduced to a great extent, and the life and property safety of people is guaranteed to a great extent.
