Abstract
The utility model provides an aluminum rear anti-collision beam assembly which comprises an aluminum rear anti-collision beam, two aluminum energy absorbing boxes and two aluminum installing supports, wherein the aluminum rear anti-collision beam is in the shape of a long strip; the two aluminum energy absorbing boxes are respectively welded at the inner sides of two ends of the rear anti-collision beam, and are respectively to be a hollow cylindrical body which is formed in an extruding way at an equal cross section; and the two aluminum installing supports are respectively welded at one ends, which are far away from the rear anti-collision beam, of the two energy absorbing boxes, and the installing supports are flat plate bodies which are formed in the extruding way at the equal cross section. Each part in the aluminum rear anti-collision beam assembly provided by the utility model is made from the aluminum material, so that the weight of a vehicle can be effectively reduced, and the oil consumption and the exhaust gas emission of the vehicle can be reduced.
Description
Technical field
The utility model relates to automobile technical field, relates in particular to a kind of aluminum back buffer beam assembly.
Background technology
Automobile in the process of moving, if by other objects during from rear impact, the acceleration change that automobile is instantaneous and momentum are very large, if the structure design of vehicle body is undesirable, body tail can not be very to the energy that produces of absorption collision, vehicle body then can by badly damaged, cause casualties.In order to absorb the impact energy of collision, guarantee occupant's survival space, the structure design of vehicle body is not more firm better, vehicle body front and rear part structure has suitable flexibility, the absorbed energy so that when bumping, smashed distortion, alleviate crash acceleration, reduce the impact to the crew module, guarantee occupant's survival space.
For addressing the above problem, be provided with aluminum back buffer beam assembly at body tail, aluminum back buffer beam assembly has energy-absorption box, the absorbed energy to be smashed distortion when bumping.The back buffer beam of traditional aluminum back buffer beam assembly and energy-absorption box are steel and make; adopt steel stamping part or machine for rolling parts; link together by spot welding or gas shield electrode holder back buffer beam and energy-absorption box, weight is heavier, so that automobile fuel consumption and exhaust emissions are higher.Studies show that about 75% oil consumption is relevant with complete vehicle quality, reduce car mass and just can effectively reduce oil consumption and discharging, the every decline 10% of car mass, oil consumption descends 8%, and discharging descends 4%.
The utility model content
The utility model purpose is to provide a kind of minimizing vehicle weight, reduces the oil consumption of automobile and the aluminum back buffer beam assembly of exhaust emissions, and it is heavier so that the problem that the oil consumption of automobile and exhaust emissions are higher to be used for solving existing aluminum back buffer beam assembly weight.
For solving the problems of the technologies described above, the utility model provides a kind of aluminum back buffer beam assembly, is installed on the afterbody of the floor side member of automobile, and described aluminum back buffer beam assembly comprises:
The back buffer beam of aluminum, described back buffer beam are strip;
The energy-absorption box of two aluminums, the two ends that are welded in respectively back buffer beam are inboard, and described energy-absorption box is the hollow tube-shape body of uniform cross section extrusion molding; And
Two mounting brackets are welded in respectively the end away from back buffer beam of two energy-absorption boxes, and described mounting bracket is the platysome of uniform cross section extrusion molding.
Preferably, described back buffer beam adopts the aluminium sheet punch forming.
Preferably, the cross sectional shape of described energy-absorption box is " worker " font.
Preferably, described mounting bracket is shaped as cuboid.
The utility model also provides a kind of automobile, comprises above-mentioned aluminum back buffer beam assembly.
The utlity model has following beneficial effect:
Each parts in the aluminum back buffer beam assembly of the present utility model are aluminum and make, and have effectively reduced vehicle weight, have reduced oil consumption and the exhaust emissions of automobile.
Description of drawings
Fig. 1 is the schematic perspective view of aluminum back buffer beam assembly of the present utility model;
Fig. 2 is the exploded perspective view of aluminum back buffer beam assembly of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, the utility model embodiment provides a kind of aluminum back buffer beam assembly 100, be installed on the afterbody of the floor side member (not shown) of automobile, be used for when bumping, being smashed distortion and absorbed energy, alleviate crash acceleration, minimizing guarantees occupant's survival space to crew module's impact.
Please also refer to Fig. 2, aluminum back buffer beam assembly 100 comprises back buffer beam 110, two energy-absorption boxes 120 and two mounting brackets 130.
Wherein, back buffer beam 110 is strip, and its material is aluminium, and it adopts the aluminium sheet punch forming.
Two energy-absorption boxes 120 are welded in respectively the inboard, two ends of described back buffer beam 110.Energy-absorption box 120 is the hollow tube-shape body of aluminum, and it adopts the uniform cross section extrusion molding, and its cross section is " worker " font.
Aluminum back buffer beam assembly of the present utility model 100 adopts aluminiums to make, and weight only has 1/3 of the energy-absorbing cylinder that adopts steel plate, and weight loss effect is obvious.Studies show that about 75% oil consumption is relevant with complete vehicle quality, reduce car mass and just can effectively reduce oil consumption and discharging, the every decline 10% of car mass, oil consumption descends 8%, and discharging descends 4%.Therefore adopt the aluminum back buffer beam assembly 100 of aluminum so that all reductions of oil consumption and discharging.
The forming process of all parts of aluminum back buffer beam assembly 100 of the present utility model is as follows:
Energy-absorption box 120 is made through production processes such as blanking and cuttings.
Each parts in the aluminum back buffer beam assembly of the present utility model are aluminum and make, and have effectively reduced vehicle weight, have reduced oil consumption and the exhaust emissions of automobile.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
