Reasonable employment plastics can be effectively realized automotive light weight technology.Manufacturing field at orthodox car, there is keen competition in metal and plastics
Relation.And in metal-plastic mixed structure technical field, metal can be combined with plastics for manufacturing parts.Metal-
The key feature of plastic mixed structure is, has played metal strength height and the lightweight advantage of plastics simultaneously, mutually auxiliary at bi-material
The structural behaviour of parts is greatly improved under the effect coordinated.At present, metal-plastic mixed structure is in front-end module, instrument
Dish and front bumper have obtained some application.Automobile B column is to support car door, top cover and the critical piece of threshold, logical
Often being carried out punch forming by high-strength steel sheet to form, its weight is relatively big, is badly in need of lightweight.Meanwhile, automobile B column is resistant to again
The vitals of side impact, its intrusion volume, intrusion speed and deformation pattern decide the life security of occupant, are therefore realizing vapour
Its crash-worthiness is ensured during car B column lightweight.Metal-plastic mixed structure is applied to automobile B column design, both can alleviate B
The weight of column, can improve again the Side-impact safety of B column, it is also possible to simplifying the manufacturing process of B column, prospect is the widest
Wealthy.
Summary of the invention
1, goal of the invention:
It is an object of the invention to provide a kind of automobile B column being made up of high strength steel and plastics, be based primarily upon metal and plastics
Integrated injection molding technology, is aided with the plastics reinforcement that geometry is complicated while reducing B column high strength steel plate thickness,
Both meet the demand of automotive light weight technology, improve again B post impact strength.
2, technical scheme:
Based on lightweight, crashworthiness and integrated design concept, the present invention provides a kind of lightweight and crashworthiness good
Automobile B column, to solve the problem of B column heavier-weight during current auto industry produces, use metal and plastics integration
A kind of automobile B column being made up of high strength steel and plastics that injection molding process is made, is shown in accompanying drawing, and this structure includes the first steel
Plate and the second plastics reinforcement, the position annexation between them is: the first steel plate and the second plastics reinforcement pass through thermoplasticity
Injection molding process adheres to be fixed together.
Described first steel plate is self-made components, uses the yield strength high strength steel more than 600MPa, and its thickness is 1.0～1.2mm,
Making through heat stamping and shaping technique, interior surface uses ball blast technique to improve the roughness of inner surface, improves the note with plastics
Moulding adhesion, its function is as the main supporting body of automobile B column, is absorbed collision energy by the certain deformation of self and is protected
Protect occupant safety.
Described second plastics reinforcement is self-made components, by thermoplastic, and particularly polyamide 66 (PA66) or polyphenylene sulfide (PPS)
Plastics, by forming in the first inner surface of steel plate injection mo(u)lding, the thickness of reinforcement is 0.8～1.2mm, and its function is to improve vapour
The strength and stiffness of car B column, absorb energy when collision by self-deformation and destruction.
3, the present invention " a kind of automobile B column being made up of high strength steel and plastics ", its advantage is as follows:
(1). lightweight.The high strength steel plate thickness used due to the present invention is less than the steel plate thickness in traditional all-metal B column, therefore
The weight of B post is significantly reduced.
(2). intensity is high.The present invention arranges plastics reinforcement at B post key reasonable stress, compared to traditional all-metal B post,
Impact strength effectively improves.
(3). simplify the geometry of B column punch-out, owing to arranging plastics reinforcement in inside, so need not again to
Steel plate stamping is pressed into the convex-concave profile of complexity, and diel is simplified.
In a word, the present invention both can meet lightweight demand to automobile now, can improve again automobile side crash-worthiness, simultaneously and vapour
Car existing production technology compatibility is good, has the most wide application prospect.
Accompanying drawing explanation
In conjunction with accompanying drawing, by the description to following indefiniteness preferred embodiment, the present invention be may be better understood；
The structural representation of the automobile B column that the high strength steel of Fig. 1 present invention and plastics are constituted；
In figure, symbol description is as follows: 1-the first steel plate, 2-the second plastics reinforcement.
Detailed description of the invention
Below in conjunction with the accompanying drawings the embodiment of the present invention is described in further detail:
As shown in drawings, a kind of automobile B column being made up of high strength steel and plastics of the present invention, including with lower component: the first steel
Plate the 1, second plastics reinforcement 2.Position annexation between them is: the first steel plate and the second plastics reinforcement pass through thermoplastic
Property integrated through injection molding moulding process adhere to be fixed together.
Owing to the second plastics reinforcement 2 is connected with the upper portion of the first steel plate 1 in the present embodiment, enhance automobile B column
