Vehicle-mounted emergency guide board

Abstract

The invention relates to the technical field of vehicle safety accessories, and particularly relates to a vehicle-mounted emergency guide board. A front surface of an LED lamp board is provided with adynamic guide sign, and the emergency guide board is placed at the top of a vehicle during use to achieve a warning effect. The dynamic guide sign comprises an arrow sign and / or a red fork sign and / or a running water sign, and signal lamp pieces are evenly distributed on the inner surface of the dynamic guide sign. The LED lamp board is provided with a USB charging wire and an interface of the USB charging wire can be configured to three power connection modes: 1, the interface is connected with a vehicle power supply interface; 2, the interface is connected with a mobile power supply; and 3the interface is connected with a dry cell box. Potential safety hazards are reduced through a good warning effect, a driver only needs to open a guide warning board around a vehicle and connect a power source, the warning board does not need to be placed remotely, and safety accidents are reduced; the emergency guide board is suitable for various power supply modes, is particularly matched with apower supply interface of the vehicle, and can be prevented from being turned off due to power failure; and the guide board has high stability, and is prevented from being blown down by wind or beingvibrated down by passing vehicles.

Description

technical field [0001] The invention relates to the technical field of vehicle safety accessories, in particular to a vehicle emergency guide plate. Background technique [0002] The existing triangular emergency warning signs are mostly made of ordinary plastics. Although they have a certain reflective warning function, the warning effect is very limited. The vehicles behind cannot be recognized in the distance and in rainy and foggy days. In this case, a longer braking distance is required, and the existing triangular warning sign has a weaker warning effect, so the driver has to manually take it to a place far from the faulty vehicle for placement. First, it has a high potential safety hazard. Once the speed of the vehicle behind is too fast or the buffer distance placed by the driver is not enough, or the warning triangle cannot play a warning role after being blown down, it is very easy to have a safety accident, or even a car crash; the second is the triangle warning s...

[0002] The existing triangular emergency warning signs are mostly made of ordinary plastics. Although they have a certain reflective warning function, the warning effect is very limited. The vehicles behind cannot be recognized in the distance and in rainy and foggy days. In this case, a longer braking distance is required, and the existing triangular warning sign has a weaker warning effect, so the driver has to manually take it to a place far from the faulty vehicle for placement. First, it has a high potential safety hazard. Once the speed of the vehicle behind is too fast or the buffer distance placed by the driver is not enough, or the warning triangle cannot play a warning role after being blown down, it is very easy to have a safety accident, or even a car crash; the second is the triangle warning sign In order to have a sufficient safety distance when placing it, it needs to be placed far away from the faulty vehicle, and this buffer distance is therefore occupied, and the traffic is likely to cause congestion, and it is easy to cause a series of traffic accidents
