Description
Technical field
The present invention relates to foam plastics product and automotive field, more particularly, to a kind of three-dimensional foam plastic part and the automotive component and the motor vehicles that comprise this product.
Background technology
Foam plastics, is the family macromolecule material formed in solid plastic by a large amount of gas micropore dispersions.Due to foam plastics there is light weight, the advantage such as heat conductivity is low, hygroscopicity is little, good springiness, specific strength are high, sound insulation is adiabatic, therefore it is widely used and does that noise reduction is heat insulation, anti-freezing and heat-insulating, buffering are shockproof and lightweight structural material, be also used widely in transportation, building construction, packaging, articles for daily use and national defense and military industry.At automotive field, for reducing the overall weight of vehicle, saving the purposes such as oil consumption, foam plastics is also increasingly favored.For example, it is possible to the numerous parts with " sandwich " structure made together with fibre reinforced plastics with foam plastics on vehicle, such as vehicle floor, center tunnel, covering for roofs, energy-absorption box, side door, hood, back door, baggage-compartment partition etc..
In a lot of application (such as, automotive field), it is necessary to foam plastics is made 3D shape.A kind of known method is that the standard foam unit of plastic purchased or plastic foamboard are machined into desired three dimensional shape.But, general plastic foam mechanical processing characteristics is not good, is difficult to even cannot process the 3D shape of complexity.And, the 3D shape that can process is additionally subjected to the restriction of the size of standard foam unit of plastic or the plastic foamboard purchased.
Accordingly, it would be desirable to a kind of new technique, utilize this technique can be easily manufactured by three-dimensional foam plastic part, especially there is the foam plastics product of complex three-dimensional forms.
Summary of the invention
It is an object of the invention to provide a kind of easily fabricated and shape by the three-dimensional foam plastic part of raw material size limitation.
For this, the present invention relates to a kind of three-dimensional foam plastic part, it is characterised in that it is assembled by multiple elements cut out from plastic foamboard, adjacent elements be connected to each other and between very close to each other, the overall profile that the plurality of element is constituted is the profile of described three-dimensional foam plastic part.Owing to described element is the two-dimensional components of plane, it is absent from the change of cross sectional shape in a thickness direction, therefore process compared with an overall three-dimensional foam plastic part with direct mechanical, cut out chip component from standard foam plastic plate to be obviously more prone to, the appreciable impact of the bad machining property of foam plastics will not be subject to.Therefore, easily fabricated according to the three-dimensional foam plastic part of the present invention, the requirement of process equipment is relatively low, advantageously reduce the production cost of enterprise.It addition, it is without the restriction being subject to raw material size, it is possible to have extremely complex 3D shape.
It is one or more that three-dimensional foam plastic part according to the present invention can also include in following characteristics:
By the plurality of element, combination by bonding, laser welding, by means of the plug-in unit or these modes that run through them assembles described three-dimensional foam plastic part.In one embodiment, described plug-in unit is solid beam.In another embodiment, described plug-in unit is hollow pipe.
Preferably, described plug-in unit is also made up of foam plastics.In such manner, it is possible to reduce the gross weight of described three-dimensional foam plastic part.
In one embodiment, the plurality of element cuts out from identical plastic foamboard.In another embodiment, the plurality of element cuts out from different plastic foamboards.As such, it is possible to produce the three dimensional articles with multiple density different pieces according to concrete application demand.
The set that the material of described plastic foamboard is constituted selected from polyamide, polypropylene, polrvinyl chloride, polystyrene, polyurethane, Lauxite, it is preferable that its density is lower than 0.2g/cm3, this is energy-conservation for loss of weight in automotive field is very favorable.
