Frame 8 is respectively arranged at the both sides of back seat buttress brace 6.Spare tire installment support 8 can also be arranged at it
His position, introduces the most one by one at this.
Further, the rear floor structure that the embodiment of the present invention provides also includes that being arranged at two spare tyres installs
Longitudinally reinforced beam 9 between support 8, further enhancing the intensity of rear floor structure.
Wherein, rear floor 1 is provided with waling 16 with the corresponding region of longitudinally reinforced beam 9.
As shown in figures 1 and 3, in order to improve the intensity of spare tyre housing region 17, in the present embodiment after
Floor panel structure also includes being arranged on spare tyre housing region 17 and reinforcing plate 10.Wherein, spare tyre accommodates district
The bottom-right location in territory 17 is provided with reinforcing plate installing zone 110, is provided with reinforcing plate 10；And reinforcement
Including multiple spare tyre walings 18 and multiple spare tyre cross reinforcing 19, it is distributed in standby with certain rule
On tire housing region 17.
In the present embodiment, crossbeam 2 and floor sill 3 are installed before three rows of seats and set by spot welding is fixing
It is placed on rear floor 1, uses three layers of spot welding mode to weld, same, longeron 4 and afterwards on rear floor
Under plate, longeron 5 is fixedly installed on rear floor 1 by spot welding, uses three layers of spot welding mode to weld.
In this specification, each embodiment uses the mode gone forward one by one to describe, and each embodiment stresses
Being the difference with other embodiments, between each embodiment, identical similar portion sees mutually.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this
