Summary of the invention
In view of this, be necessary to provide collision prevention girders and the automobile that a kind of intensity is high and cost is low.
In order to address the above problem, according to an aspect of the present invention, provide a kind of collision prevention girders, it comprises header board, is fixed on honeycomb structure and rear plate on described header board; Described honeycomb structure is contained in described rear plate, and described rear plate is fixed on described header board.
Preferably, described honeycomb structure comprises that some cross sections are orthohexagonal hollow pillar, and described hollow pillar is matrix and arranges.
Preferably, described hollow pillar is in the splicing of mutually aliging of the rib of every adjacent two hollow pillars of direction side by side, described hollow pillar and the splicing of mutually aliging of the corresponding sides of every adjacent two hollow pillars of column direction.
Preferably, the length of side in the cross section of described hollow pillar and the described honeycomb structure intensity of bearing is inversely proportional to.
Preferably, each described hollow pillar is made by sheet steel or thin aluminum sheet folding forming.
Preferably, described rear plate comprises the accommodating box that takes the shape of the letter U and two fixed edges that extended by the ora terminalis of the two opposite sides plate of described accommodating box respectively, and described honeycomb structure is contained in described accommodating box, and described fixed edge is fixed in described header board.
Preferably, described collision prevention girders also comprises some hold-down bolts, described header board is provided with some fixed orifices, each described fixed edge is provided with through hole, and the place of aliging with each through hole of each fixed edge is welded with a project-welding nut, and each hold-down bolt is fixed in corresponding project-welding nut after passing successively described fixed orifice, described through hole.
On the other hand, the present invention also provides a kind of automobile, and it comprises vehicle body, and described vehicle body comprises vehicle frame and above-mentioned collision prevention girders, and described collision prevention girders is fixed in front end or the rear end of described vehicle frame.
Preferably, also be fixed with the collision box on described rear plate, described collision box is fixed in described vehicle frame.
Collision prevention girders of the present invention and automobile utilize the mechanical property of honeycomb structure to reach required strength and stiffness, and honeycomb structure is to make by folding forming, do not need large-scale die apparatus and very high energy consumption, have reduced cost.
Description of drawings
Fig. 1 is the package assembly schematic diagram of collision prevention girders of the present invention, and collision prevention girders comprises header board and is fixed on honeycomb structure on header board;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1;
Fig. 3 is that in Fig. 2, honeycomb structure is fixed on package assembly schematic diagram on header board.
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Please refer to Fig. 1, the invention provides a kind of automobile, this automobile comprises the vehicle body (not shown).Vehicle body comprises the 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 collision box 3, and collision prevention girders 1 is fixed on vehicle frame by collision box 3.
Please in conjunction with reference Fig. 2, collision prevention girders 1 comprises header board 11, be fixed in the honeycomb structure 13 of header board 11 and be fixed on rear plate 15 on header board 11.Honeycomb structure 13 is contained in rear plate 15.Collision box 3 is fixed on rear plate 15.
Particularly, in the present embodiment, header board 11 is platysome, and contiguous its ora terminalis place, up and down is provided with respectively some fixed orifices 111.
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.Honeycomb structure 13 comprises that some cross sections are orthohexagonal hollow pillar 131.These hollow pillars 131 are matrix to be arranged, wherein, and the rib of every adjacent two hollow pillars 131 of the direction setting splicing of mutually aliging side by side, and the splicing of mutually aliging of the corresponding sides of two every adjacent hollow pillars 131 of column direction setting.
It is fixed that the requirement of strength that the size of each hollow pillar 131 is born according to honeycomb structure 13 needs is come, when the intensity that need to bear when honeycomb structure 13 is 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, thereby the intensity that can bear is just large; Otherwise, the intensity that need to bear when honeycomb structure 13 hour, the length of side of the regular hexagonal section of hollow pillar 131 is just large.Be 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 the rigidity that need to bear when honeycomb structure 13 was large, each hollow pillar 131 was just made by sheet steel; The rigidity that need to bear when honeycomb structure 13 hour, each hollow pillar 131 is just made by thin aluminum sheet (being namely aluminium foil).
The making material that it is pointed out that hollow pillar is not limited to described sheet steel, thin aluminum sheet.
Honeycomb structure 13 and high strength steel plate be in the situation that same weight has good mechanical stability, and honeycomb structure 13 is to make by folding forming, do not need large-scale die apparatus and very high energy consumption, so cost can reduce.
By above-mentioned narration as can be known: 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 to make by folding forming, do not need large-scale die apparatus and very high energy consumption, reduced cost.
Above-described is only an embodiment of the invention.For the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
