Compound rear protective plate of truck

Abstract

The invention relates to a compound rear protective plate of a truck. The rear protective plate is composed of a collision bumper and at least two steel plates, wherein the outermost layer of the steel plate consists of a gel coat layer, a structural layer, a gluing layer, a base coat layer and a steel plate layer; the steel plates are parallel to each other and gaps are arranged among the steel plates, and the gaps are larger than 2cm and smaller than 8cm; the gel coat layer is of neopentyl glycol-o-phthalate resin, the structural layer is composed a plurality of epoxy furan resin layers and fibrages, and both the gluing layer and the base coat layer take the epoxy furan resins as the major material; and the collision bumper is a hydraulic buffer. The rear protective plate has favorable gloss, colorableness and favorable properties such as water proofing, chemical resistance, corrosion resistance, wear resistance, impact resistance and the like, is light in weight and favorable in collision rebound resilience, can effectively prevent small impact and buffer huge impact and vibration, and simultaneously protects the collision bumper. To sum up, the compound rear proactive plate of the truck has the advantages of safety, high efficiency, light weight, corrosion resistance and beautiful appearance.

Description

technical field [0001] The invention relates to a device installed at the rear of a freight car, which can effectively reduce casualties and vehicle damage when a car collides with a freight car. Belongs to automotive safety protection components. Background technique [0002] At present, automobile traffic accidents occur frequently, including a large number of automobile rear-end accidents, especially rear-end collisions with trucks. The consequences of accidents are extremely serious. The cab of the accident-causing car is deformed, endangering the driver's life. The consequences of such accidents are related to the structure of the rear of the truck. The center of gravity of the truck is high, and the space at the bottom of the box is large. The space at the bottom of the box is the root of the serious consequences of rear-end collisions. Improving the structure of the rear of the truck can play a positive role in reducing the consequences of rear-end collisions. [000...

AI Technical Summary

Problems solved by technology

[0003] Throughout the freight vehicles of various brands, various tonnages, and various manufacturers, there is no external safety protection device. For safety reasons, most of them install well-shaped or strip-shaped protective bars at the rear of the vehicle by themselves, because most of them are made and installed by themselves. , not only the appearance is not elegant, the use is inconvenient, but also the safety protection function is low. When the car rear-end collides, because there are strip metal parts when the two cars collide, it often increases the casualties of personnel and the damage of the vehicle. At present, there is no protection Products with good functions and used as safety protection devices for the exterior of freight cars to prevent rear-end collisions of cars
