Embodiment
Fig. 7 below in conjunction with the accompanying drawings to Figure 11 makees into one to a kind of reinforced rear big beam assembly of the present invention
Step describes in detail.
The present invention it is a kind of it is reinforced after big beam assembly, refer to Fig. 7-11, including integral type it is rear greatly
Beam reinforcing plate 2 and dividing plate 5, the rear crossbeam reinforcing plate 2 is set up on rear crossbeam body 1, after described
Crossbeam reinforcing plate 2 is fixedly connected with the rear top of crossbeam body 1, the rear front end of crossbeam reinforcing plate 2
Outside is provided with least first rib 3, it is described after the leading inside of crossbeam body 1 be provided with least one piece the
Two ribs 4, first rib 3 and second rib 4 respectively spirogyrate and concave shaped, it is described
First rib 3 is extended in the rear crossbeam body cavity body with second rib 4,5, the dividing plate
After described in the cavity of crossbeam reinforcing plate 2, described 5 liang of sides of dividing plate respectively with it is described after crossbeam reinforcing plate
2 inwalls are fixedly connected.So, first rib 3 is set in the rear front end outer side of crossbeam reinforcing plate 2, in institute
State the rear leading inside of crossbeam body 1 and second rib 4 is set, the first rib 3 and the second rib 4 extend to
Afterwards in the cavity of crossbeam body 1, by the first rib 3 and a small cavity of the second rib 4 formation, apply
Fill after liquid is flowed into by the cavity in the cavity of crossbeam body 1, so as to strengthen flowing of the coating liquid in vehicle body weight
