accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 1.
In figure: 1 crossbeam, 2 longerons, 3 L shaped connecting panels, 4,5 connect flat board, 6 all side beams, 7 rear curb girders, 8 brace panels, 9 angle block of right angle.
The specific embodiment
As shown in Figure 1 to Figure 3, power battery box of electric vehicle bracket comprises underframe and lays respectively at top, both sides, underframe front and back all side beam 6 and rear curb girder 7.Underframe comprises two longerons 2 and 1, two girder space setting of two crossbeams and between two longerons, connects two longerons.All side beam is all identical with the lateral length of underframe with the equal horizontally set of rear curb girder and their length, all side beam both ends and rear curb girder both ends are all by L shaped connecting panel 3 corresponding being supported on the front and back end of two longerons respectively, the riser lower end of each L shaped connecting panel and the welding of corresponding longeron end, the flat board of each L shaped connecting panel is connected with corresponding all side beam end or rear side beam end by bolt.All side beam right-hand member is provided with the connection flat board 5 for being connected with chassis side rail with rear curb girder right-hand member.
Longeron, crossbeam, all side beam and rear curb girder all adopt channel-section steel, and all down, all side beam is relative with rear curb girder opening for longitudinal and cross beam opening.Adopt channel-section steel structure, increased greatly the structural strength of crossbeam and longeron, reduced at electric automobile during traveling process medium power battery box bracket and be hit and produce the possibility of distortion.The main bearing beam Cross section Design of underframe is reasonable, has greatly increased the vertical stiffness of underframe, has larger horizontal rigidity simultaneously.In the situation that not increasing underframe own wt, improved rigidity and the intensity of structure, be conducive to underframe and when forced vibration, reduce amplitude, thereby actv. is avoided the impact of the vibration of vehicle frame in driving process on battery pack.
Between all side beam two legs, by brace panel 8, support, weld with all side beam two legs respectively on the upper and lower both sides of brace panel; Between rear curb girder two legs, by brace panel, support, weld with rear curb girder two legs respectively on the upper and lower both sides of brace panel.
The right and left of each L shaped connecting panel is all welded with triangle brace panel.
Connecting flat board connects by two angle block of right angle 9 and all side beam Huo Hou curb girder reinforced company.
All interval has lightening hole on all side beam waist and on rear curb girder waist.
Bolt adopts closely-pitched hexagonal flange toothed bolt, the flat board that is each L shaped connecting panel is connected with corresponding all side beam end or rear side beam end by closely-pitched hexagonal flange toothed bolt, compare with welding connection structure, avoided the stress of weld metal zone to concentrate and the possible problems such as weld defect, bolt connects insensitive to manufacturing errors, convenient for assembly, closely-pitched hexagonal flange toothed bolt has higher anti-loosening property, has improved the reliability connecting.
Major part of the present invention is selected section bar, manufactures selection conveniently, without punching press, bending equipment, less demanding to production technology, and convenient production, manufacture, reduced cost.
