Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the EPP automobile bumper structure of the present invention comprises a crossbeam 1, a buffer plate 2 and a base plate 3, the crossbeam 1 is “U” shaped and adapted to the vehicle body, the crossbeam 1 and the base plate 3 are fixedly connected to form a bar body, and the base plate 3 passes through four A connection hole 9 is connected and fixed on the car body, and the buffer plate 2 is arranged in the bar body. The buffer plate 2 is connected to the beam 1 through two guide rods 5 , one end of the guide rod 5 is movably inserted into the beam 1 , and the other end is fixedly connected with the buffer plate 2 . Each guide rod 5 is covered with a buffer spring 6, one end of the buffer spring 6 is fixedly connected to the beam 1, the other end is fixedly connected to the buffer plate 2, and the buffer spring 6 is covered wit...

Abstract

The invention discloses an EPP vehicle bumper, and belongs to the field of vehicle manufacturing. The EPP vehicle bumper comprises a transverse beam matched with a vehicle body, a buffer plate, a base plate and at least two guide rods; the transverse beam is fixedly connected with the base plate to form a bar body, and the buffer plate is located in the bar body; one end of each guide rod is movably inserted into the transverse beam, and the other end of each guide rod is fixedly connected with the buffer plate; each guide rod is sleeved with a buffer spring, one end of each buffer spring is fixedly connected with the transverse beam, and the other end of each buffer spring is fixedly connected with the buffer plate; and a gap between the transverse beam and the buffer plate is filled with EPP energy absorption blocks, and a gap between the buffer plate and the base plate is filled with EPP energy absorption belts. Through the EPP energy absorption blocks between the transverse beam and the buffer plate and the EPP energy absorption belts between the buffer plate and the base plate, impact force generated at the moment when vehicle collision occurs can be rapidly and effectively absorbed, harms to drivers and damage to a vehicle are effectively avoided or reduced, and the EPP vehicle bumper is simple in structure, convenient to install and low in manufacturing cost.

Description

technical field [0001] The invention relates to an automobile bumper, in particular to an EPP automobile bumper, which belongs to the field of automobile manufacturing. Background technique [0002] Automobile bumpers are an important part of automobiles, which can effectively avoid or slow down the damage caused by the huge impact force of automobile collisions to people and vehicles, and play an important role in preventing traffic accidents and reducing economic losses in modern society. However, the prior art automobile bumper cannot effectively absorb the impact force generated instantaneously when the automobile collides, resulting in poor protection performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an EPP automobile bumper that can effectively absorb impact force and has good protection performance. [0004] In order to solve the above technical problem...
