Passenger vehicle front bumper

Abstract

The invention provides a passenger vehicle front bumper. The bumper has a telescopic folding function, when impacted, the bumper can absorb a considerable part of impact force, and safety of personnelin a passenger vehicle is guaranteed. The passenger vehicle front bumper mainly comprises an anti-collision crossbeam arranged in front of a passenger vehicle head, the anti-collision crossbeam is fixedly connected to longitudinal beams symmetrically arranged on the two sides of the anti-collision crossbeam, and a stretching mechanism is arranged in the direction perpendicular to the anti-collision crossbeam; the passenger vehicle front bumper further comprises a lower air cylinder and an upper air cylinder used for driving the stretching mechanism and the longitudinal beams to stretch and retract; and piston rods of the lower air cylinder and the upper air cylinder are connected to a rear tappet of the stretching mechanism and the longitudinal beams. Cylinder bodies of the lower air cylinder and the upper air cylinder are fixedly installed on a vehicle frame at the bottom of the passenger vehicle. The stretching mechanism mainly comprises an upper tappet, the lower tappet, a left folding arm, a right folding arm and a control center, all the components of the stretching mechanism are connected through hinge structures, and the stretching mechanism is connected with the longitudinal beams through hinge structures similarly.

Description

technical field [0001] The invention relates to the field of passenger cars, in particular to a front bumper of a passenger car. Background technique [0002] With the development of society, people's living standards are getting higher and higher, and the number of times they go out is increasing.

[0003] Due to the very special transport nature of passenger cars, the safety requirements for passenger cars are also very high; most of the bumpers used in passenger cars are made of metal, which are only connected to the passenger car and have no buffering and impact absorption functions. . [0004] The design of this bumper can only protect the front of the bus from damage caused by some slight scratches. When encountering some sudden collision accidents, the entire bumper cannot provide a buffer for the vehicle, and the i...
