Abstract
The utility model discloses a beam of an MDC rear bumper. The beam comprises a beam main body and an energy-absorbing box. The beam main body is of an arc-shaped structure and made of GMT materials, two ends of the beam main body respectively fix the energy-absorbing box, and the energy-absorbing box is made of elastic materials and is of a structure in a shape like a Chinese character 'gong'. The beam of the MDC rear bumper has the advantages of being good in buffer performance and improving the service life.
Description
Technical field
The utility model relates to a kind of Federal bumper technical field, specifically is a kind of MDC post-bumper beam.
Background technology
Traditional Federal bumper is to be made by metal material mostly, and directly is fixed on the car body.After automobile collision occurs during at low speed driving, because of there not being buffering, it is damaged, can only change or keep in repair, reduced the life-span of bumper/spoiler; And when low speed driving is met the pedestrian, also can cause bigger injury to the pedestrian.
The utility model content
The purpose of the utility model provides a kind of MDC post-bumper beam, has overcome the above-mentioned deficiency of prior art, has cushion characteristic preferably, improves service life.
In order to reach above-mentioned design goal, the technical scheme that the utility model adopts is following:
A kind of MDC post-bumper beam comprises main body of cross-beam, energy-absorbing box, the arcuate structure that said main body of cross-beam is processed for the GMT material, and the main body of cross-beam two ends are fixing energy-absorbing box respectively, and said energy-absorbing box is " bow " font structure of elastic material.
Said main body of cross-beam two ends are through the bolt energy-absorbing box that locks respectively.
The beneficial effect of the described MDC post-bumper beam of the utility model is: the metal energy-absorbing box between car body and bumper/spoiler can absorb a large amount of impact forces, forms certain buffering, helps protecting car body and pedestrains safety.
The bumper beam main body of GMT material has cushion characteristic preferably, can bear slight impact and does not have a damage, improves service life.
Description of drawings
Fig. 1 is the scheme drawing of the utility model.
Fig. 2 is the exploded drawings of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
Shown in Fig. 1-2, the described MDC post-bumper beam of the utility model embodiment comprises main body of cross-beam 1, energy-absorbing box 2, bolt 3; The arcuate structure that said main body of cross-beam 1 is processed for the GMT material, main body of cross-beam 1 two ends be fixing energy-absorbing box 2 respectively, and said energy-absorbing box 2 is fixed in the car body; During use, bumper beam main body 1 combines with energy-absorbing box 2, can be in collision bumper beam main body 1 and energy-absorbing box 2 common absorbing impact energy; When low speed collision, can not damage vehicle body; The bumper beam main body 1 of GMT material has the characteristic of recovering shape, and this characteristic will reduce the service expenditure in the daily middle Minor Accident, improves the practical life of main body of cross-beam 1.
Said main body of cross-beam 1 two ends are convenient to dismounting, are changed through the bolt 3 energy-absorbing box 2 that locks respectively.
" bow " font structure that said energy-absorbing box 2 is an elastic material.
The preferred embodiment of this specific embodiment the utility model can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
