Description
Technical field
The utility model patent is related to automobile safety protective technical field, is a kind of automobile with quincunx endergonic structure
Collision energy absorbing box.
Background technique
As various automobiles enter huge numbers of families as transport and walking-replacing tool, automobile in use,
Be frequently encountered some urgent perhaps burst accidents such as by other Vehicular impact or encounter bad weather cause with trees,
Electric pole etc. is hit.When being hit, vehicle will receive very big momentum, generate biggish hinder so that vehicle is by high speed wink
Between be down to it is static, originally biggish kinetic energy almost all be converted to vehicle it is interior can, make vehicle by serious destruction and deformation,
Lead to the injures and deaths of personnel in cockpit, therefore in vehicle safety design, is typically employed in vehicle front and rear part installation one and absorbs this
The energy-absorption box of a little energy, for vehicle when colliding, energy-absorption box absorbs collision energy by the conquassation deformation of itself, to extenuate
The safety of personnel in vehicle and cockpit is protected in impact to vehicle frame.
Buccal glyph shaped structure is used in most vehicle energy absorption box design now, which can absorb one in collision process
Fixed collision energy, but due to using the hollow buccal glyph shaped structure of simple four panel body, overall structure is almost simultaneously when collision
Plastic period is carried out, leads to absorb that energy is relatively low and energy absorption ability waste is serious.Additionally due to collapse energy-absorption process is in
Simple linear variation, it is obviously insufficient for the protective capacities of the collision process such as complicated collision, secondary collision.
For this problem, the invention proposes one kind to have plum-shaped structure energy-absorption box.The main collision cross-section of the energy-absorption box
In plum-shaped structure, this aspect can enter the process of plastic deformation by the variation control energy-absorption box of cross sectional shape, effectively
Energy absorption ability is promoted, while being promoted and just brushing up against the material integral stiffness in side impact direction, complicated collision and secondary can be significantly improved
The protective capacities of collision has great importance and is worth for promotion automotive safety.
Summary of the invention
In order to overcome the problems, such as that existing energy-absorption box absorbs little energy, to the protection deficiency of complicated and secondary collision etc., originally
Utility model patent proposes a kind of energy-absorption box with plum-shaped structure.The main collision cross-section of the energy-absorption box is in plum-shaped structure,
Energy absorption performance is effectively promoted, while significantly improving the protective capacities for complicated collision and secondary collision, by collision energy-absorbing
The raising of ability realizes that driver and passenger drive the promotion of safety.
The technical solution adopted by the utility model to solve its technical problems is that: choose the suction that plate thickness is 1.0mm-6.0mm
It can box metal material.With energy-absorption box perimeter and height for parameter blanking, it is energy-absorption box perimeter that metal material, which is cut into length,
Height is the plate of energy-absorption box design height.Plate folding is square by bullodozer, is hollow by electric arc welding
Cell type.Again with 1/5 energy-absorption box perimeter and height for parameter blanking, it is 1/5 energy-absorption box week that metal material, which is cut into 4 block lengths,
Length, the highly plate for energy-absorption box design height.By bullodozer respectively by 4 pieces of plate bending semicirculars in shape, pass through arc welding
It is in quincunx that it is integrally welded, which to be carried out edge-to-edge, along short transverse for 4 pieces of semicircle plates.Finally quincunx weldment is put into
It is integrally welded in hollow cell type part, ultimately form quincunx energy-absorbing box structure.
Specific manufacturing process mainly includes the techniques such as the cutting preparation, bending process, assembly welding of metal material.
One: metal material cutting.In conjunction with Service Environment, the energy-absorption box metal that plate thickness is respectively 1.0mm-6.0mm is chosen
Material.According to energy-absorption box geometric dimension and design requirement, it is energy-absorption box perimeter that sheet metal is cut into length respectively with plate shearing machine,
Height is that one piece of plate of energy-absorption box design height is used as plate 1 and length for 1/5 energy-absorption box perimeter, is highly energy-absorption box
Four pieces of plate of design height are used as plate 2.
Two: bending process.Plate 1 is subjected to the quartering as unit of equal length, it will with bending machine at each Along ent
Plate 90 ° of bending at same direction, are made the identical rectangular box of side length, and be structure as a whole by electric arc welding.By plate 2 with
Equal length is that unit is halved, with bending machine by plate bending semicircular in shape at Along ent, by arc welding by four pieces
It is in quincunx that it is integrally welded, which to carry out edge-to-edge, along short transverse for semicircle plate.
Three: assembly welding.Quincunx weldment is put into hollow cell type part, the side of plum blossom weldment and hollow cell type are made
The box face of part is tangent, and is welded along direction tangential, and the processing of quincunx energy-absorption box is finally completed.
The advantages of the utility model patent is: structure is simple, easy to make, and stability is good, significantly improves energy-absorption box
Energy-absorbing is horizontal and complexity is collided and the energy absorption ability of secondary collision.
