Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , the tail beam 8 with slideways connects the hinged support 11 with the vehicle frame 10 of the commercial vehicle through a hinge, and the four fixed installation holes 14 left on the upper end make it bolted to the vehicle frame 1, so that Such as figure 2The tail beam 8 is fixed with the vehicle frame 1, and forms an integral body with the vehicle frame. The tail crossbeam 8 can make two small pulleys 21 slide freely in its slideway 13, two electrically controlled springs 22 one ends are connected with the hinged support 12 in the slideway, and one end is respectively hinged a small pulley 21. Another spring 6 is fixed on the spring fixed support 23 of crossbeam.

[0034] see figure 2 , The left camera 3 is installed on the outside of the anti-collision beam, the middle camera 15, the right camera 16...

Abstract

The invention relates to a commercial vehicle tail anti-collision device, and discloses a commercial vehicle active control anti-collision mechanism for protecting passengers and vehicles on multiple angles. The mechanism has multiple anti-collision functions, and can actively control the mechanism parameter to reduce the collision harm to vehicles and passengers. The impact energy of the vehicle in rear-end collision is absorbed by mating reaction of a spring and a damper, the collisions at different positions are actively controlled, thereby reducing the damage of vehicles and passengers by the vehicle rear-end collision accident; meanwhile, a camera and a radar mounted on the mechanism can actively control the spring damper through an electric control mechanism, and lighten the harm caused by collision greatly through actively adjusting the parameters of the spring and the damper; moreover, multiple driving modes can be used for realizing the mated work of the radar and the camera, thereby protecting passengers, in particular to children, buildings, and vehicles, and realizing the safe driving.

Description

[0001] Technical field: [0002] The invention relates to the active safety of a commercial vehicle, which is an anti-collision mechanism used for protecting pedestrians and vehicles during the running of the commercial vehicle. [0003] technical background: [0004] Worldwide, more than 500,000 people die in traffic accidents every year, and 10 million people are injured in traffic accidents. On average, at least one person dies in traffic accidents every minute. With the continuous development of my country's economy and society, the output of commercial vehicles The number of roads and vehicles keeps increasing, while the development of roads and traffic management are relatively backward, leading to an increase in the incidence of traffic accidents year by year, of which rear-end accidents of commercial vehicles account for a large proportion; commercial vehicles, especially trucks, have a high body height and a long body length. Longer, and the body height of passenger cars...
