Description
Technical field
The utility model relates to automotive field, particularly relates to a kind of back buffer beam for automobile.
Background technology
The vehicle frame afterbody of China's major part vehicle uses the crashproof girder steel of foam or plasthetics making, its Performance comparision is soft and fragile, easily cracked or badly damaged under relative force collision, lack impact resistance and buffer capacity, actv. protective action is not possessed when rear-end collision, automobile tail can be made once collide seriously impaired, its service expenditure is strengthened, and arranges the life security of passenger after endangering when certain seriously knocks into the back.
Utility model content
The purpose of this utility model is, for above-mentioned defect, to provide a kind of back buffer beam for automobile.
The utility model solves the technical scheme that its technical matters adopts:
A kind of back buffer beam for automobile, five metals material is adopted to be processed into back buffer beam for automobile, its intensity ratio foam or plasthetics intensity large, safety factor of travel is improved, comprise base, energy-absorbing buffering box, girder, described girder two ends are fixedly welded with energy-absorbing buffering box, the top of energy-absorbing buffering box is connected with girder, the bottom of energy-absorption box is connected with base, base is connected with car body crossbeam, the profile of described energy-absorbing buffering box is quadrangular, and four stupefied limits of quadrangular are equipped with at least two groove nodes caved inward; The cross section of described girder is surrounded by upper beam, underbeam, curb girder, and described upper beam is short compared with underbeam, and two described curb girders are symmetrical links together described upper beam and underbeam, and described curb girder presents " W " crimp shape; End limit place on described base is provided with mounting hole, and the geometric centre position on described base is provided with breather hole.
Described girder inside is hollow, is provided with the sheet material of oblique arrangement in the position of described girder boring, and described sheet material is rhabodoid structure on the cross section of described girder; On the cross section of described girder, connect described upper beam, underbeam between described upper beam, underbeam by least two pack supports, each is organized described support and forms " V " font structure by two rhabodoids.
The material of described girder is metal material.

Detailed description of the invention
Shown in composition graphs 1, Fig. 2, Fig. 3, Fig. 4, a kind of back buffer beam for automobile, comprise base 1, energy-absorbing buffering box 2, girder 3, described girder two ends are fixedly welded with energy-absorbing buffering box, the top of energy-absorbing buffering box is connected with girder, and the bottom of energy-absorption box is connected with base, and base is connected with car body crossbeam, the profile of described energy-absorbing buffering box is quadrangular, and four stupefied limits of quadrangular are equipped with at least two groove nodes 4 caved inward; The cross section of described girder is surrounded by upper beam 5, underbeam 6, curb girder 7, and described upper beam is short compared with underbeam, and two described curb girders are symmetrical links together described upper beam and underbeam, and described curb girder presents " W " crimp shape; End limit place on described base is provided with mounting hole 8, and the geometric centre position on described base is provided with breather hole 9.
Described girder inside is hollow, is provided with the sheet material of oblique arrangement in the position of described girder boring, and described sheet material is rhabodoid structure 10 on the cross section of described girder; On the cross section of described girder, connect described upper beam, underbeam between described upper beam, underbeam by least two pack supports, each is organized described support and forms " V " font structure by two rhabodoids.
The material of described girder is metal material.
Described base passes through described mounting hole with car body crossbeam by screw and is connected.
Described girder section adopts two " W " type pleated structure, and this structure has good crumple effect, and beam body can guide impact force crumple deformation step by step stressed time, is alleviated the impact force of automobile by the crumple of self.
Energy-absorption box adopts groove design of node, the upright structure of this structure structural rate possesses good crumple effect, and energy-absorption box is stressed, and crumple deformation layer by layer more easily occurs, and is alleviated the impact force of automobile by the crumple deformation of self.
Base plate center have employed air gate design, when welding, can produce a large amount of smog, causes welding lines uneven, the smog produced time air gate design can discharge welding, makes welding evenly attractive in appearance.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
