Embodiment
Embodiment of the present utility model is described below in detail, wherein from beginning to end same or similar label represent it is identical or
Similar element or the element with same or like function.The embodiments described below with reference to the accompanying drawings are exemplary,
It is intended to be used to explain the utility model, and it is not intended that to limitation of the present utility model.
The novel lightening enhanced type automobile crossbeam according to the utility model embodiment described with reference to the accompanying drawings.Fig. 1 is
The structural representation of the novel lightening enhanced type automobile crossbeam of the utility model embodiment.It includes upper flange 1, lower wing plate 2, stood
Plate 3 and flange punching 4.
Upper and lower wing plate 1,2 forms I-shaped structure with riser 3.
Flange punching 7 includes the annular flange 5 protruded to the side of riser 3, and the annular inner edge of flange 5 is circumferentially connected with annular
Stand along 6, annular is vertical to form punching 7 along 6 middle part.Punching 7 is irregular hole, and relative to circular hole, irregular Kong Gengneng is further
Stress concentration around eliminating.Irregular hole is preferably in arc notch shape from narrow to wide.Annular flange 5 is vertical along 6 with annular
Shape is consistent, and annular is vertical consistent along 6 ring width.Ring width is consistent in its circumferential direction so that annular is vertical along 6 weeks
It is consistent to the active force of annular flange 5 upwards, in the absence of weak link, it is possible to increase the intensity of crossbeam.
Set to be staggered up and down in riser 3 and be provided with multiple flange punchings 4, so as to can either further mitigate crossbeam certainly
Weight, and can increase crossbeam overall intensity and resistance to torsion.Riser 3 includes the main part at rear portion and anterior gooseneck portion, gooseneck portion
Protuberance upwards, main part and goose neck junction use variable-diameter structure.Advantageously, riser 3 divides for three-dimensional portion and gooseneck portion.Wherein
In the middle part of the main part and left and right sides is equipped with some flange punchings 7, and flange is not set in the middle part of gooseneck portion and close to the side of main part
Punching 4, side of the gooseneck portion away from main part are provided with flange punching 4.Because the height of riser 3 is smaller at gooseneck portion, riser 3 is not allowed
It is yielding, and multiple flange punchings 4 are set in goose neck end one end, it is therefore intended that make the intensity of enhancing goose neck end and resist
The property turned round, the power that goose neck end is subject to are delivered to the main part of reducing and the junction in gooseneck portion, and power is broken off, and further increase
The bulk strength and resistance to torsion of powerful beam.
As shown in figure 3, the present embodiment has made further improvement to the connected mode of flange, vertical edge, i.e.,：Outside riser 3
It is First Transition circular arc 8 between side and the outside of annular flange 5, is second between the inner side of riser 3 and the inner side of annular flange 5
Transition arc 9, the radian of the second transition arc 9 are more than the radian of First Transition circular arc 8.Stood with annular in the outside of annular flange 5
Along being the 3rd transition arc 10 between 6 outside, the inner side of annular flange 5 and annular are vertical along being the 4th transition between 6 inner side
Circular arc 11, the radian of the 4th transition arc 11 are more than the radian of the 3rd transition arc 10.It is local that stress concentration refers to stress in object
The phenomenon increased, appears in body form place jumpy, especially breach, hole, groove and has at rigid constraint, because
This, the radian inside and outside junction is different, and suffered stress is just different, so as to avoid certain of flange punching 4 from stress mistake occur
Situation about deforming upon greatly, so as to further enhance the intensity of this crossbeam riser and resistance to torsion.
While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that：
These embodiments can be carried out with a variety of changes, modification in the case where not departing from principle and objective of the present utility model, replaced
And modification, the scope of the utility model are limited by claim and its equivalent.
