Description
Technical field
It the utility model is related to field of automobile, and in particular to a kind of automobile shank beam.
Background technology
With the development of automotive engineering and the raising of people's awareness of safety, the protection of automobile is no longer limited to protection in-car
Passenger, but be expanded to the pedestrian with car collision, when automobile and pedestrian collision, be generally all vehicle body directly with
Pedestrian shank portion is in contact, so as to directly contribute injury to pedestrian shank portion.When automobile is with pedestrian collision, pedestrian's is small
Leg will be come to harm at first, and the degree of injury of pedestrian shank will be also further had influence on because shank injury can not stand or fall
Afterwards to the further injury of pedestrian.Automobile shank beam is arranged on the part of automotive front, can be in low speed impact, to row
People is effectively protected, and prevents pedestrian by serious personal injury, and play one to the important spare part in automobile front chamber
Fixed protective effect.
But current automobile shank beam is mostly steel design, crossbeam is that steel extrudes crossbeam, and section form is mainly rectangle, is inhaled
Energy box material is (high intensity) steel, and cylindrical cavities, the independent punching press of mounting seat, punching are welded into again using the punching press of upper and lower two-piece type elder generation
Hole forming, most connection is respectively welded in energy-absorption box and crossbeam, mounting seat at last.Automobile shank beam manufacturing procedure is more complicated, crossbeam
Process includes extrusion, and stretch bending, energy-absorption box process includes punching press, welds, and base process includes punching press, punching；Shank beam assembly work
Sequence includes the welding of crossbeam and left and right energy-absorption box, the welding of left and right energy-absorption box and base, makes shank beam processing cost higher, and
Because material is all to use high strength steel, the heavier-weight of final finished, it is impossible to effectively buffering is formed, meanwhile, to high intensity
Steel rely on for a long time.
Utility model content
The purpose of this utility model is exactly to provide a kind of automobile shank beam to solve the above problems, and is meeting anticollision guarantor
On the premise of protecting system function, its weight, cost are effectively optimized.
The purpose of this utility model is achieved through the following technical solutions：
A kind of automobile shank beam, installed in the preceding lower end of automobile, including crossbeam and it is connected to crossbeam both ends and left and right is right
The energy-absorption box of title, described energy-absorption box are made up of preceding energy-absorption box and rear energy-absorption box, alveolate texture are provided with inside energy-absorption box, to carry
The intensity of high shank beam and good energy-absorbing effect, energy-absorption box material use PP-30TD%.
Described alveolate texture includes multiple hexagonal holes, and hexagon opposite side is 9-11mm apart from size.
Then described preceding energy-absorption box and rear energy-absorption box are rubbed respectively by plastics integrated injection molding using hot plate welding or vibrations
Wipe weldering connection.
Described preceding energy-absorption box and rear energy-absorption box profile are square.
The top of described preceding energy-absorption box is provided with the through hole with riveting transverse beam.
Described rear energy-absorption box bottom is provided with base, and base is provided with the through hole being bolted with car body.
Described crossbeam is the circular arc crossbeam of aluminium punching press, including intermediate transverse girder section and the side bar section at both ends, to meet C
NCAP-5 star crash requirements, collision prevention girders aluminum alloy material use the mainly 7 series high strength aluminium alloys based on zinc, such as 7075-6T.
Compared with prior art, crossbeam of the present utility model uses aluminium punching press, and energy-absorption box uses injection molding, respectively
By riveting or bolt connection between part, manufacturing procedure is few, and finished weight is light, reduces Product processing cost, improves processing
Production efficiency.Be provided with alveolate texture inside energy-absorption box, while reduction energy-absorption box weight, energy-absorbing when can improve collision with
And shock-absorbing capacity, reduce and high strength steel is depended on unduly, reduce that manufacturing process is complicated and caused fraction defective improves, avoid
The failure that the corrosion of steel of shank beam is brought, make vehicle lightweight, reduce the environmental pollution that carbon emission is brought, production effect can be improved
Rate and saving car sheet, effectively reduce the injury to pedestrian, protect front deck important spare part to exempt from damage jointly with front anti-collision beam, from
And bring more effective protection.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of automobile shank beam, as Figure 1-4, including energy-absorption box 2 and the two parts of crossbeam 1, the agent structure of energy-absorption box 2
Section form is alveolate texture, and for each peak nest into regular hexagonal, hexagon opposite side is 10mm apart from size, energy-absorption box 2 by
Front and rear two parts composition, the preceding inside of energy-absorption box 3 is alveolate texture, and outer shape is rectangle, is provided with the top of preceding energy-absorption box 3
4 through holes for passing through the riveting of rivet 5 with crossbeam；The inside of energy-absorption box 4 is alveolate texture afterwards, and outline is rectangle, rear energy-absorbing
Box 4 is provided with base, and 4 through holes are provided with base, for being connected with car body by bolt 6.The crossbeam 1 be aluminium punching press and
Larger to obtain enough stiffnesses into, intermediate surface curvature, both sides curvature is smaller and has 4 installations and is used for through hole
Connected with left and right energy-absorption box.The material of energy-absorption box 2 uses injection molding, and manufacturing procedure is few, and finished weight is light, reduces product and adds
Work cost, processing efficiency is improved, alveolate texture is provided with inside energy-absorption box, while reducing energy-absorption box weight, can be improved
Energy-absorbing and shock-absorbing capacity during collision, so as to bring more effective protection.
