Expressway vehicle driving distance early warning device

Abstract

The invention discloses an expressway vehicle driving distance early warning device which comprises a protection box, an early warning plate, a camera shooting frame and a weather plate, wherein the protection box is embedded in the inner wall of embedding plates, two sets of mounting frames are mounted on the inner wall of the protection box, the early warning plate is mounted in the mounting frames, and a bottom plate is mounted at the bottom of the protection box. A first monitoring window and a second monitoring window are mounted in the bottom plate through groove plates, shaft rods are mounted on the inner walls of the first monitoring window and the second monitoring window correspondingly, the surfaces of the shaft rods are sleeved with camera frames, and embedding grooves are formed in the front face and the back face of the embedding plate correspondingly. An auxiliary connecting plate is slidably mounted in the embedding groove, a mounting box is fixed to the front face of the auxiliary connecting plate, and a weather plate is mounted in the mounting box.By arranging the early warning plate, targeted interval warning information can be provided for vehicles running on the same-direction lane on the expressway, and the warning effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of machine distance early warning, in particular to a vehicle distance early warning device on expressways. Background technique [0002] When the vehicle is driving on the expressway, a certain distance needs to be maintained between the front and rear vehicles, so that when the vehicle in front has a situation, the vehicle behind has a certain braking distance and reaction time to take braking measures to avoid rear-end collisions. When the vehicle is driving on the expressway, it needs a distance warning device to provide appropriate distance warning information to remind passing vehicle drivers to maintain a suitable distance, thereby reducing the occurrence of safety accidents. [0003] The defective that existing distance warning device exists is: [0004] 1. The comparative document CN210895816U discloses a highway early warning device based on vehicle-to-vehicle communication, "including a protectiv...
