Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment, is easy to be well understood to
The utility model, but they do not constitute restriction to the utility model.
As shown in figure 1, power battery box 1 is arranged on floor and rear floor lower section in vehicle body, power battery box 1 is first fixed to
On battery case framework beam 2 below battery case, it is being fixed on vehicle body by battery case framework beam 2.
As shown in Fig. 2 the planform of battery case framework beam 2, be by left side longeron 3, the right longeron 4, front beam 5,
Two crossbeams 6, the 3rd crossbeam 7, the 4th crossbeam 8 and rear cross beam 9 are constituted.The pallet 10 for carrying battery pack block is arranged on the He of front beam 5
Between second cross beam 6, be fixed to side longeron and crossbeam on weld bolt 11 on.Between the 3rd crossbeam 7 and the 4th crossbeam 8,
The pallet for carrying battery can be equally placed between 4th crossbeam 8 and rear cross beam 9.
As shown in figure 3, for the sectional drawing of left side longeron 3, by beam 31 of the top section in several fonts and lower section section in falling
The laminating of beam 32 of several fonts is formed by welding, and the right longeron 4 and remaining crossbeam section are same, is all double a few font butt welding structures
Into closed cross-section.For in the prismatic beam of several fonts, rolling techniques being adopted on its moulding process, can reduce mould into
This.
As shown in figure 4, front beam 5 is welded together by upper square beam 51 and the laminating of lower square beam 52, the up end of beam 51
Step 511 is provided with, is met and the thick height of the material of side longeron junction.
As shown in figure 5, the right longeron 4 is welded together by upper square beam 41 and the laminating of lower square beam 42, in the company with front beam 5
Place is met, on the right square beam 42 is provided with breach 421 under longeron, for avoiding four layers of weldering.
