In one in the first height and second of channel assembly channel assembly the second height can root need unrestricted choice, i.e., channel in first
Assembly along the first height of first direction Z and second channel assembly between the second height of first direction Z there are difference in height,
Preferably, in second channel assembly along first direction Z the second height with first in channel assembly along the first high of first direction
The difference of degree is 60~160mm.The replacement of vehicle not of the same race is realized by the middle channel assembly 130 of disassembling, assembling and replacing different height,
Such as when new automobile is mounted to two drive automobiles, select that there is channel assembly in the first of the first height to be installed, it can shape
The automobile lower body for driving automobile at two selects that there is channel assembly in the second of the second height to be installed, can form 4 wheel driven vapour
The automobile lower body of vehicle, that is to say, that for same money vehicle, the automobile lower body of two drive automobiles and 4 wheel driven automobile is able to achieve platform
The universal design of change.
As shown in figure 3, rear floor assembly 140 is connected to preceding floor assembly 120 and middle channel assembly 130 is total far from front panel
At 112 one end.Floor assembly 140 includes back seat crossbeam 141 and rear floor 148 afterwards.The removable company of back seat crossbeam 141
It is connected to rear floor 148, the length direction of back seat crossbeam 141 is parallel to third direction Y.For channel assembly 130 in cooperating
Replacement, back seat crossbeam 141 can be selected from one of the first back seat crossbeam and the second back seat crossbeam, and the first back seat is horizontal
Channel assembly cooperates in beam and first, assembly cooperation in channel in the second back seat crossbeam and second, and the second back seat crossbeam edge
The third height of first direction Z is greater than fourth height of the first back seat crossbeam along first direction Z.First back seat crossbeam and
Two back seat beam structures are roughly the same, and wherein each includes rear floor upper beam 1411 and is connected to rear floor upper beam
1411 rear floor lower beam 1412.Floor upper beam 1411 includes third interconnecting piece 142, the 4th interconnecting piece 144 and connects afterwards
It is connected to the back seat upper beam portion 146 between third interconnecting piece 142 and the 4th interconnecting piece 144.First back seat crossbeam or second
The third interconnecting piece 142 of back seat crossbeam is removable to be connected to the first preceding floor 125, the second preceding floor 126 and middle passageway housings
The one end of body portion 136 far from enging cabin assembly 110, the 4th interconnecting piece 144 is removable to be connected to rear floor 148.Back seat
Crossbeam 141 along third direction Y both ends respectively it is removable be connected to before floor assembly 120 122 He of the first threshold side bar
Second threshold side bar 124, and the first threshold side bar 122 of preceding floor assembly 120 and the second threshold side bar 124 are along second direction
X extension is connected to rear floor 148, and is integrally formed with rear floor 146.In the present embodiment, the first back seat crossbeam and second
Channel assembly corresponds cooperation in channel assembly and second in back seat crossbeam and first, specifically, corresponding with money vehicle
Two drive automobile lower body, and channel assembly in the first back seat crossbeam and first is selected to be coupled, the corresponding 4 wheel driven with money vehicle
Automobile lower body then selects channel assembly in the second back seat crossbeam and second to be coupled, to realize that two drive automobile and 4 wheel driven
Hardware and software platform universal design between automobile.
Automobile lower body 100 proposed by the present invention includes enging cabin assembly 110, preceding floor assembly 120, middle channel assembly
130 and rear floor assembly 140, and by the back seat crossbeam 141 and middle channel assembly 130 of floor assembly 140 after switching, it can
Realize that two drive the conversion between automobile and 4 wheel driven automobile, the hardware and software platform for realizing that two drive the lower body between automobile and 4 wheel driven automobile leads to
With design.Therefore, the automobile lower body of two drive automobiles is converted into the automobile lower body of 4 wheel driven automobile or by 4 wheel driven automobile
When automobile lower body is converted into the automobile lower body of two drive automobiles, new automobile lower body is made without re-molding, is only needed more
The back seat crossbeam 141 and middle channel assembly 130 for changing rear floor assembly 140 can facilitate realization to convert, so as to shorten automobile
The period of exploitation reduces development cost and reduces development risk.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Detail in mode can carry out technical solution of the present invention a variety of simple within the scope of the technical concept of the present invention
Modification, these simple variants all belong to the scope of protection of the present invention.It is as described in the above specific embodiments each specific
Technical characteristic can be combined in any appropriate way in the case of no contradiction.In order to avoid unnecessary heavy
Multiple, the invention will not be further described in various possible combinations.
