Embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in Fig. 2 the utility model includes the automobile that rear girder assembly 1, rear cross beam by vehicle right and left both sides are constituted
Vehicle frame, rear floor assembly 3, the rear automobile frame junction of floor assembly 3 are provided with lug boss, and the automobile frame is built in institute
State in lug boss.This example increases crew module empty by making the floor of rear floor assembly 3 decline 46mm built in automobile frame
Between；The utility model realizes that crew module's spatial optimization is designed while controlling vehicle height in certain overall height.
As shown in Figure 3 and Figure 4, girder assembly 1 includes rear crossbeam 11 and rear crossbeam inner panel 12, the rear crossbeam after this example
11 and rear crossbeam inner panel 12 constitute hollow cavity, rear crossbeam inner panel 12 welds the top of crossbeam 11 in the rear.This practicality is new
Type is divided into rear crossbeam inner panel 12 and rear crossbeam two parts about 11 by by built in rear girder assembly 1, constitutes in closing
Cavity body；Whole bearing capability is improved, bigger active force can be born when being collided.
As shown in Figure 5-Figure 8, rear crossbeam inner panel 12 is divided into the preceding inner panel 121 of rear crossbeam and rear crossbeam reinforcing plate 122 by this example
Two parts, the rear crossbeam reinforcing plate 122 is set close to the tailstock.Afterwards crossbeam 11 be divided into rear crossbeam leading portion 111 and with rear crossbeam
Rear big 112 two parts of beam connection that leading portion 111 is fixedly connected, the rear big beam connection 112 and rear crossbeam reinforcing plate 122
It is fixedly connected.Make rear crossbeam inner panel 12 and the type face of rear crossbeam 11 relatively easy, it is easy to be molded, be closed cavity after welding, be difficult
Resilience；Lowered molding difficulty again by part piecemeal, beneficial to mould development.Wherein, this example is due to rear big beam connection 112
For sect of insensitiveness, using 1.4mm thin plates（The crossbeam part of other automobile frames is 1.6mm）, and it is designed with vertical muscle.It is big after reduction
The thickness of beam connection 112, loss of weight 0.15kg, while by touching requirement after increasing the vertical muscle of energy-absorbing, satisfaction.
As shown in Figure 9 and Figure 10, floor assembly 3 is divided into back seat lower plate 31 and spare tyre cabin structure 32 two zero after this example
Part, using multi-step structure, the back seat lower plate 31 be fixedly connected at spare tyre cabin structure 32 in the rear crossbeam.This
Outside, rear floor crossmember connector 2 is provided with above this example rear cross beam, the rear floor crossmember connector 2 is arranged on the back seat
Lower plate 31 and the top of the junction of spare tyre cabin structure 32, are fixedly connected with rear cross beam, and form a cavity with rear cross beam.So as to
The bearing capacity of crossbeam is improved, raising strength and stiffness are finally reached, the purpose of vehicle torsional rigidity is lifted.The He of back seat lower plate 31
The size of spare tyre cabin structure 32 is only the half of rear floor assembly 3, and part easy-formation, mould maintenance cost is low, and rigidity is better than flat
Whole rear floor, part is unlikely to deform, efficiently solve floor poor rigidity after prior art, it is yielding the problem of.
The middle row seat chair mount point 311 of this example is arranged in back seat lower plate 31, and shown back seat mount point 4 is set respectively
Put on rear floor crossmember connector 2 and rear girder assembly 1, this example middle row seat chair base surface and back seat base surface are provided with
Floor crossmember connector 2 after mount point increase before 100mm differences in height, back seat, further increases installation strength, and make institute
State middle row seat chair and back seat to set in scalariform, be the Z-direction leg room that the 3rd row passenger adds 100mm.
This example back seat lower plate 31 is provided with the boss 312 for avoiding fuel tank, the first heavy platform 313 for avoiding seat and avoids day
The heavy platform 314 of the second of line, this example spare tyre cabin structure 32 is provided with spare tyre cabin 321, and the inclined automobile side in spare tyre cabin 321 is set, institute
Spare tyre cabin structure 32 is stated in the exhaust pipe assembly corresponding position of automobile opposite side provided with the platform 322 for avoiding blast pipe.
The multi-step structure of this example back seat lower plate 31 and spare tyre cabin structure 32, makes crew module add 50mm Z-direction phase
To space.This example back seat lower plate 31 reduces floor, while protect again by the alternate structure of the heavy platform 313 of boss 312 and first
The installation of fuel tank and seat is demonstrate,proved；Inclined design second sinks platform, meets the installation of low-frequency antenna, and low-frequency antenna install after height
It is highly consistent with rib, carpet is tiled, improve perceived quality, while nor affect on the 3rd row passenger to put pin empty
Between.The side to the right of this example spare tyre cabin 321 is arranged, avoids the row that disappears.The depth 220mm of this example spare tyre cabin 321, with floor after spare tyre installation
With high, the mounting design of spare tyre, when ensureing that bodywork height is constant, the installation of three rows of seats is met, meanwhile, after increasing
Standby case space.
Set by of the present utility model, make the relatively existing MPV reductions overall height 150-200mm of vehicle height, effectively lifting
Tire grabs ground ability, can greatly reduce windage, reduce oil consumption, meanwhile, control vehicle height in certain overall height while,
Realize that crew module's spatial optimization is designed.
Embodiment described above is better embodiment of the present utility model, and it is new not to limit this practicality with this
The specific implementation scope of type, scope of the present utility model includes being not limited to present embodiment, all according to the utility model
The equivalence changes made are in protection domain of the present utility model.
