Abstract
The utility model discloses an energy absorption box of a bumper. The energy absorption box comprises two different-size hollow prism structures with the cross sections being regular hexagons, wherein the hollow prism structures are embedded together, the cross sections of the hollow prism structures are parallel to each other and have the same center line, the adjacent hollow prism structures are connected through a reinforcing plate, and two edges on the same side of the two parallel faces of the outer layer hollow prism structure are respectively provided with a guiding hole. According to the energy absorption box, the collapsing portion can be effectively determined, the collapsing direction can be guided, the energy absorption box is easy to form in production, and no crack exists; the energy absorption box is simple in structure, reasonable in yield strength and particularly suitable for being installed on an automobile for use.
Description
Technical field
The utility model relates to auto parts and components, more particularly, relates in particular to a kind of bumper energy absorption box.
Background technology
In driving process, for reducing the injury that cause of collision to body structure and occupant, require body structure must possess the ability of energy-absorbing and resistance to deformation, while being collision happens, its collision energy must be absorbed by the privileged site of body construction, reduces as much as possible the acceleration/accel of Vehicular impact.In daily life of today, the bumper/spoiler with energy-absorption box has been one of indispensable auto parts and components.
Existing the most conventional bumper energy absorption box structure is divided into following several: the one, there is no guiding groove, and in the time that energy-absorption box produces crumple, crumple position and direction are uncertain, easily make two subsidiary risks; The 2nd, adopt the guiding groove of pcketing formula, because product stretch ratio is low, not easy-formation and easily cracking.In addition, most energy-absorption box structures are too complicated, cause yield strength too high, reduced on the contrary the protective effect that occupant is played.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can determine crumple location guide crumple direction and the rational bumper energy absorption box of yield strength without guiding groove.
The technical solution of the utility model is achieved in that a kind of bumper energy absorption box, comprise that two cross-sectional planes are regular hexagon and the hollow prism structure that varies in size, described hollow prism structure nests together, the transverse cross-section parallel of described hollow prism structure and its cross-sectional plane be line of centers altogether, between described adjacent hollow prism structure, connect by brace panel, on two ribs of two parallel faces homonymies of described outer hollow prism structure, be equipped with a bullport.
As to further improvement of the utility model, the center of circle of described bullport is all located at 1/6th rib strong points apart from end.
As to further improvement of the utility model, the angle α that the regular hexagonal cross section of described two hollow prism bodies differs is 30 °.
As to further improvement of the utility model, described brace panel quantity is three, and one side of described brace panel is all connected with three seamed edges of the third-class cyclotomy of internal layer hollow prism structure, and another side is all perpendicular to the nearest face of outer hollow prism structure.
The utility model adopt said structure, apart from 1/6th rib strong points of end, bullport is set at skin, can effectively determine crumple part guidance crumple direction, when possessing traditional guiding groove function, its more easy-formation, do not crack; Adopt brace panel to connect two-layer hollow prism structure and make this energy-absorption box yield strength more reasonable, more easily produce; The utility model is simple in structure to be made good use of, and is particularly suitable for installing and using on automobile.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
In figure: the outer hollow prism structure of 1-; 2-internal layer hollow prism structure; 3-brace panel; 4-bullport.
The specific embodiment
Consult shown in Fig. 1, a kind of bumper energy absorption box of the present utility model, comprise that two cross-sectional planes are regular hexagon and the hollow prism structure that varies in size, described hollow prism structure nests together, the transverse cross-section parallel of described hollow prism structure and its cross-sectional plane be line of centers altogether, between described adjacent hollow prism structure, connect by brace panel 3, on two ribs of two parallel faces homonymies of described outer hollow prism structure 1, be equipped with a bullport 4.
In the utility model, the center of circle of described bullport 4 is all located at 1/6th rib strong points apart from end.
In the utility model, the angle α that the regular hexagonal cross section of described two hollow prism bodies differs is 30 °.
In the utility model, described brace panel 3 quantity are three, and one side of described brace panel 3 is all connected with three seamed edges of the third-class cyclotomy of internal layer hollow prism structure 2, and another side is all perpendicular to the nearest face of outer hollow prism structure 1.
When the utility model is implemented, first outer hollow prism structure 1 is welded by brace panel 3 as stated above with internal layer hollow prism structure 2, then utilize nonstandard milling boring apparatus, / 6th rib strong points to it apart from end are processed as stated above, obtain required bullport 4.
