Wherein, as shown in Figure 4, the edge of the lower surface both sides of described roof is fillet R.Wherein, the junction of described diapire and flange forms fillet R.Wherein, the angular radius of this fillet R is 0.5-10mm.Wherein, the thickness d of described roof, diapire, flange is equal, and described thickness d is 1-15mm.Wherein, the distance b between the upper surface of described roof and the lower surface of described diapire is 30-80mm.Wherein, the width a of described roof is 40-150mm.Wherein, the width c of described diapire is 10-50mm.
It is pointed out that the above-mentioned all sizes provided are all that example illustrates, and the restriction not to the utility model protection domain.
As shown in Figure 5, Figure 6 be existing aluminium alloy element riveted joint shown in Fig. 1 time structural representation.The aluminum alloy side wall pillar of the shown battery-driven car for the utility model embodiment and roof panel cross member are arranged on the structural representation during side wall frame of vehicle.As shown in Figure 5, Figure 6, existing aluminium alloy element 1 is fixed in aluminum corner brace 3 by rivet 4 and lining 5.
The structural representation during riveted joint of the aluminium alloy element for the utility model embodiment shown in Fig. 2, Fig. 3, Fig. 4 as shown in Figure 7, Figure 8.The aluminum alloy side wall pillar of the shown battery-driven car for the utility model embodiment and roof panel cross member are arranged on the structural representation during side wall frame of vehicle.As shown in Figure 7, Figure 8, the aluminium alloy element 2 of the utility model embodiment is fixed in aluminum corner brace 3 by rivet 4.
The aluminum alloy side wall pillar of the battery-driven car of the utility model embodiment and the material of roof panel cross member are 6082T5 or 6082T6 or 7A04 or 7003 or 7005 aluminum alloys, use it as the primary member of bus body skeleton, the rigidity needs of car load can be ensured, significantly can reduce tare again, and be not easily corroded, the skeleton life-span itself reaches 25 years.Car load scrap after these parts also recoverable.
Fig. 9 is that the aluminium alloy element of the utility model embodiment is as connection structure schematic diagram when side wall pillar and roof panel cross member.Structure when Fig. 9 can illustrate that roof skeleton is connected with side wall frame, the roof panel cross member 201 of this roof skeleton is fixed on one end of attaching parts 204 by rivet, and the other end of attaching parts 204 is fixed on strength beam 203 by rivet.And the column 202 of side wall frame is fixed on the diapire outside face of strength beam 203.The aluminium alloy element of the utility model embodiment that roof panel cross member 201 wherein and column 202 all adopt.
Figure 10 be the aluminium alloy element of the utility model embodiment as side wall pillar time, structural representation when it is connected with longeron under side window.As shown in Figure 10, under side window, longeron 102 is fixed on side wall pillar 101 by rivet and attaching parts 103.The wherein aluminium alloy element of the utility model embodiment of side wall pillar 101 employing.
The skeleton major part of current passenger vehicle is concrete filled rectangular steel tube members, if directly changing rectangular steel pipe into rectangle aluminum pipe carrys out loss of weight, then intensity out of reach requirement, because the tensile strength of Q235 steel is 375-460Mpa, and the tensile strength of 6082 aluminum alloys is 310Mpa, in order to overcome this shortcoming, be I shape by these parts Cross section Design, thickness suitably thickeies, then when aluminium alloy extrusions stretching resistance can be made identical with steel pipe, weight saving 1/3, thus the object reaching loss of weight.
Now calculate and be compared as follows:
Suppose that steel frame column is 40 × 50 × 1.75 rectangular steel pipes, then the weight of its 1 meter long is 2.378kg, it is F=Rm × S to stretching resistance during yield limit, wherein Rm is tensile strength, and unit is MPa, S is rectangular steel pipe sectional area, unit is sq m, the tensile strength Rm of rectangular steel pipe Q235 is 415MPa, calculates and knows rectangular steel pipe sectional area S=0.0003 sq m, can obtain stretching resistance F=Rm × S=124500 (ox).
And the sectional area S=0.00055 sq m of the aluminium alloy element of the utility model embodiment, the tensile strength Rm=310MPa of aluminum alloy 6082T6, can obtain stretching resistance F=Rm × S, F=133300 (ox), and the weight of its 1 meter long is G=2.7g/cm
3× 550cm
3=1.48kg.It can thus be appreciated that the stretching resistance of the aluminium alloy element of the utility model embodiment when arriving yield limit is a little more than rectangular steel pipe column, and weight is only 2/3rds of rectangular steel pipe window pillar.
Stressed and existing the stressed of rectangular steel pipe of the aluminium alloy element of the utility model embodiment compares.Rectangular steel pipe (material is Q235) one end simulation by 1 meter long 40 × 50 × 1.75 applies the power of 1000N; The simulation of the Aluminum alloy column of 1 meter long (material is 6082T6) one end is applied the power of 1000N.As can be seen from Finite element analysis results, stressed one end maximum deformation quantity of existing rectangular steel pipe is 18.975mm, and stressed one end maximum deformation quantity of the Aluminum alloy column of the utility model embodiment is 18.975mm, can find out that the utility model embodiment is better than existing rectangular steel pipe.
The utility model embodiment also provides a kind of car body of aluminum alloy skeleton of battery-driven car, comprises aluminum alloy side wall pillar and the roof panel cross member of above-mentioned battery-driven car.
The utility model embodiment also provides a kind of battery-driven car, comprises the car body of aluminum alloy skeleton of above-mentioned battery-driven car.
Such scheme, the aluminum alloy side wall pillar of the new battery-driven car of proposition and roof panel cross member, its structure is more reasonable, can strengthen the structural strength of vehicle frame.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; some improvements and modifications can also be made; these improvements and modifications are exhibition results before the certainty in our utility model, also should be considered as protection domain of the present utility model.
