Truck energy absorbing anti-collision beam

Abstract

The invention relates to an anti-collision beam, more specifically to a truck energy absorbing anti-collision beam. The truck energy absorbing anti-collision beam comprises a fixing connecting frame,an anti-collision seat, an anti-collision beam, side anti-collision pieces and a linkage device. According to the truck energy absorbing anti-collision beam, the width of the anti-collision beam in anormal state is adaptive to that of a truck; when a low vehicle collides with the anti-collision beam, the anti-collision beam can absorb energy; and moreover, when the anti-collision beam suffers collision, the two side anti-collision pieces can stretch to widen the anti-collision beam so as to improve the protecting effect of the anti-collision beam. According to the truck energy absorbing anti-collision beam, the anti-collision beam can be lifted to avoid a situation that an excavator is not prone to approaching during loading goods due to too small ground clearance of the anti-collision beam. The anti-collision seat can vertically slide on the fixing connecting frame; the anti-collision beam can slide on the anti-collision seat from front to back; and the two side anti-collision piecesare slidingly connected to the left and right ends of the anti-collision seat.

Description

technical field [0001] The invention relates to an anti-collision beam, in particular to an energy-absorbing anti-collision beam for a truck. Background technique [0002] The application number is CN201810951415.5, which discloses an automobile rear anti-collision beam and an automobile. The invention discloses an automobile rear anti-collision beam and an automobile, wherein the automobile rear anti-collision beam includes an anti-collision beam main body, and the anti-collision beam main body Made of plastic through injection molding. The automobile rear anti-collision beam has the advantages of simple structure, light weight, low cost, good impact resistance and cushioning energy absorption characteristics, and can reduce the risk of secondary injury when the automobile collides. However, the anti-collision beam is fixed in shape and cannot be wide. When the car hits the anti-collision beam and skids, it will easily slide to the two ends of the anti-collision beam and s...

AI Technical Summary

Problems solved by technology

However, the anti-collision beam is fixed in shape and cannot be wide. When a car hits the anti-collision beam and slips sideways, it is easy to slide to both ends of the anti-collision beam and slide into the bottom of the truck to cause danger.
