Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Embodiment one:
A kind of power distribution cabinet of the present utility model comprises main framing structure, transitional bone shelf structure, and auxiliary skeleton structure, uses rivet between main framing structure, transitional bone shelf structure and the auxiliary skeleton structure.
As shown in Figure 1, the main framing structure plays the body supports effect, comprises the prebone frame-saw 2 that is positioned at the power distribution cabinet front side, is positioned at the back skeleton frame 1 of power distribution cabinet rear side, and prebone frame-saw 2 is the degree of lip-rounding, and back skeleton frame 1 also is the degree of lip-rounding.Prebone frame-saw 2, back skeleton frame 1 are spliced by four frames, make assembling more simple and convenient, and can improve the versatility of this power distribution cabinet general frame structure.
The transitional bone shelf structure plays connection function, formed by two upper transition skeletons 4 and two lower transition skeletons 3, as shown in Figure 2, upper transition skeleton 4 and lower transition skeleton 3 two ends are equipped with corner structure 6, corner structure 6 at right angles arranges, the main body of upper transition skeleton 4 and lower transition skeleton 3 and corner structure 6 integrally casting moulding are to improve the bulk strength of transitional bone shelf structure.Two upper transition skeletons 4 and two lower transition skeletons 3 are stitched together with rivet 8 riveted joints by four frames of corner structure 6 with prebone frame-saw 2 and back skeleton frame 1, and then surround prebone frame-saw 2 and the back skeleton frame 1 that is the degree of lip-rounding.
For strengthening the structural strength of power distribution cabinet, fixedly mount each equipment, provide routing path for equipment simultaneously, can be according to concrete needs, the auxiliary skeleton 5 of polylith is set between the main framing structure, with rivet 8 riveted joints, also use rivet 8 riveted joints between auxiliary skeleton 5 and upper transition skeleton 4 and the lower transition skeleton 3 between auxiliary skeleton 5 and prebone frame-saw 2 and the back skeleton frame 1.
As shown in Figure 7, power distribution cabinet adopts behind that fixed form is fixedly connected with car body, is provided with fixing hole 7 at back skeleton frame 1, as required, by fixing hole 7 power distribution cabinet is fixed on the car body.Also can adopt up and down fixed form, at upper transition skeleton 4, on the lower transition skeleton 3 fixing hole 7 is set, by fixing hole 7 power distribution cabinet is fixed on the car body.
As shown in Figure 5, main framing structure and transitional bone shelf structure are weight reduction, adopt aluminium alloy extrusions.Main framing structure and transitional bone shelf structure are for improving the strength and stiffness of structure, and for auxiliary skeleton provides the transition installed surface, its cross section is simultaneously
