Fig. 2 is the decomposition texture schematic diagram of Fig. 1;
Fig. 3 is that in Fig. 2, honeycomb structure is fixed on the package assembly schematic diagram on header board.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Please refer to Fig. 1, the invention provides a kind of automobile, this automobile comprises vehicle body (not shown).Vehicle body comprises vehicle frame (not shown) and is fixedly mounted on the front end of vehicle frame or the collision prevention girders 1 of rear end.Preferably, in the present embodiment, vehicle body also comprises crash box 3, and collision prevention girders 1 is fixed on vehicle frame by crash box 3.
Incorporated by reference to reference Fig. 2, collision prevention girders 1 comprises header board 11, is fixed on the honeycomb structure 13 of header board 11 and is fixed on the rear plate 15 on header board 11.Honeycomb structure 13 is contained in rear plate 15.Crash box 3 is fixed on rear plate 15.
Particularly, in the present embodiment, header board 11 is in platysome, and its upper and lower ora terminalis place contiguous is provided with some fixed orifices 111 respectively.
Honeycomb structure 13 is fixed on the first surface of header board 11, and preferably, in the present embodiment, honeycomb structure 13 is welded on the first surface of header board 11.It is orthohexagonal hollow pillar 131 that honeycomb structure 13 comprises some cross sections.These hollow pillars 131 are arrangement in matrix, and wherein, the rib of often adjacent two hollow pillars 131 that direction is arranged side by side aligns splicing mutually, the splicing and the corresponding sides of two often adjacent hollow pillars 131 of column direction setting are alignd mutually.
The size of each hollow pillar 131 needs the requirement of strength of bearing to determine according to honeycomb structure 13, when honeycomb structure 13 needs the intensity of bearing large, the length of side of the regular hexagonal section of hollow pillar 131 is just little, like this, in identical surface elemant, the number of hollow pillar 131 is just many, thus the intensity that can bear is just large; Otherwise when honeycomb structure 13 needs the intensity hour of bearing, the length of side of the regular hexagonal section of hollow pillar 131 is just large.Namely: the intensity that the length of side of the regular hexagonal section of hollow pillar 131 and honeycomb structure 13 bear is inversely proportional to.
When honeycomb structure 13 needs the rigidity of bearing large, each hollow pillar 131 is just made up of sheet steel; When honeycomb structure 13 needs the rigidity hour of bearing, each hollow pillar 131 is just made up of thin aluminum sheet (being namely aluminium foil).
It is pointed out that the making material of hollow pillar is not limited to described sheet steel, thin aluminum sheet.
Honeycomb structure 13 and high strength steel plate have good mechanical stability when same weight, and honeycomb structure 13 is obtained by folding forming, and do not need large-scale die apparatus and very high energy consumption, therefore cost can reduce.
Rear plate 15 comprises the accommodating box 151 taken the shape of the letter U and two fixed edges 153 extended by the ora terminalis of the two opposite sides plate of accommodating box 151 respectively.Rear plate 15 is fixed on header board 11 by fixed edge 153, and honeycomb structure 13 is contained in accommodating box 151.Particularly, accommodating box 151 stay bearing plate 154 that comprises side plate 152 and extended to the homonymy of side plate 152 by the ora terminalis up and down of side plate 152; Two fixed edges 153 to be extended dorsad away from one end of side plate 152 by each stay bearing plate 154 respectively and form.
Crash box 3 is fixed on side plate 152 away from a side of fixed edge 153.More preferably, in the present embodiment, also comprise some hold-down bolts 6, each fixed edge 153 is provided with some through holes 156, and the place of aliging with each through hole 156 of each fixed edge 153 is welded with a project-welding nut 157; Each hold-down bolt 6 successively through being fixed in corresponding project-welding nut 157 after the fixed orifice 111 of header board 11, through hole 156, so that rear plate 15 is fixed on header board 11.
Described from above-mentioned: collision prevention girders of the present invention and automobile utilize the mechanical property of honeycomb structure 13 to reach required strength and stiffness, and honeycomb structure 13 is obtained by folding forming, do not need large-scale die apparatus and very high energy consumption, reduce cost.
Above-described is only an embodiment of the invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
