Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in further details.
As shown in Fig. 2 the present invention include to be made up of the rear girder assembly 1, rear cross beam of vehicle right and left both sides automobile frame,
Floor assembly 3 afterwards, 3 automobile frame junction of the rear floor assembly is provided with lobe, and the automobile frame is built in described convex
In the portion of rising.This example declines 46mm by the built-in floor for making rear floor assembly 3 of automobile frame, increases crew module space；This
Invention realizes the design of crew module's spatial optimization while controlling car load height in certain overall height.
As shown in Figure 3 and Figure 4, after this example, girder assembly 1 includes rear crossbeam 11 and rear crossbeam inner panel 12, the rear crossbeam
11 and rear crossbeam inner panel 12 constitute hollow cavity, rear crossbeam inner panel 12 welds the top of crossbeam 11 in the rear.The present invention is led to
Crossing will be built-in for rear girder assembly 1, and is divided into rear crossbeam inner panel 12 and rear crossbeam two parts about 11, constitutes the middle cavity of closing
Body；Whole bearing capability is improved, and 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 front inner panel 121 of rear crossbeam and rear crossbeam reinforcing plate 122 by this example
Two parts, the rear crossbeam reinforcing plate 122 is arranged near the tailstock.Afterwards crossbeam 11 be divided into rear crossbeam leading portion 111 and with rear crossbeam
112 two parts of the rear big 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 11 type face of rear crossbeam relatively easy, it is easy to molding, be closed cavity after welding, be difficult
Resilience；Lowered molding difficulty by part piecemeal again, beneficial to mould development.Wherein, this example is due to rear big beam connection 112
For sect of insensitiveness, using 1.4mm thin plate（The crossbeam part of other automobile frames is 1.6mm）, and it is designed with vertical muscle.Big after reduction
The thickness of beam connection 112, loss of weight 0.15kg, while indulging muscle by increasing energy-absorbing, touches requirement after satisfaction.
As shown in Figure 9 and Figure 10, after this example, floor assembly 3 is divided into back seat lower plate 31 and spare tyre cabin structure 32 two zero
Part, all using multiple stage stage structure, the back seat lower plate 31 be fixedly connected at spare tyre cabin structure 32 in the rear crossbeam.This
Outward, rear floor crossmember connector 2 is provided with above this example rear cross beam, and the rear floor crossmember connector 2 is arranged on the back seat
Lower plate 31 and the top of 32 junction of spare tyre cabin structure, 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, lift the purpose of car load torsional rigidity.31 He of back seat lower plate
The half of the size of spare tyre cabin structure 32 only rear floor assembly 3, part easy-formation, mould maintenance cost is low, and rigidity is better than flat
Whole rear floor, part is unlikely to deform, and efficiently solves floor poor rigidity, yielding problem after prior art.
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
100mm difference in height, floor crossmember connector 2 after mount point increases before back seat, increase installation strength further, and make institute
Middle row seat chair and back seat are stated in scalariform setting, be the Z-direction leg room that the 3rd row passenger increased 100mm.
This example back seat lower plate 31 is provided with and avoids the boss 312 of fuel tank, avoids the first heavy platform 313 of seat and avoid 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 the spare tyre cabin 321 is arranged, institute
Stating spare tyre cabin structure 32, the platform 322 for avoiding exhaustor is provided with the aerofluxuss pipe assembly corresponding position of automobile opposite side.
This example back seat lower plate 31 and the multiple stage stage structure of spare tyre cabin structure 32, make crew module increased the Z-direction phase of 50mm
To space.This example back seat lower plate 31 reduces floor, while protect again by the alternate structure of boss 312 and the first heavy platform 313
The installation of fuel tank and seat is demonstrate,proved；Inclined design second sinks platform, meets the installation of low-frequency antenna, and height after low-frequency antenna is installed
Highly consistent with rib, so that carpet is tiled, improve perceived quality, while nor affect on the 3rd row passenger put foot sky
Between.The side arrangement to the right of this example spare tyre cabin 321, avoids the row that disappears.321 depth 220mm of this example spare tyre cabin, 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.
By the setting of the present invention, make car load height existing MPV relatively reduce overall height 150-200mm, effectively improve wheel
Tire grab ground ability, can greatly reduce windage, reduce oil consumption, meanwhile, while controlling car load height in certain overall height, realize
Crew module's spatial optimization is designed.
The specific embodiment of the above is the better embodiment of the present invention, not limits the concrete of the present invention with this
Practical range, the scope of the present invention includes to be not limited to this specific embodiment, and all equivalence changes that is made according to the present invention are equal
Within the scope of the present invention.
