Embodiment
It should be noted that in the case where not conflicting, the embodiment in the present invention and the feature in embodiment
It can be mutually combined.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Embodiment one
The present embodiment is related to Floor frame structure after a kind of vehicle, and it is applied on the shorter vehicle of rear overhang, with
The Integral modes on floor after vehicle can be lifted, it is ensured that reliability of structure at rear floor.As shown in fig. 1,
Floor frame structure is included along extended a pair of the longerons 1 of the length direction of vehicle, in both sides after the vehicle
Longeron 1 between be connected with the transverse beam assembly extended in the vehicle width direction.The transverse beam assembly specifically includes company
It is connected between the longeron 1 of both sides, and close to the afterbody of vehicle, namely using the direction shown in Fig. 1 as base
Standard, is connected to the first crossbeam 2 between the top of longeron 1 of both sides.
In the present embodiment, transverse beam assembly is still further comprised relative to first crossbeam 2 close to vehicle head
The second cross beam 3 being connected between the longeron 1 of both sides of side arrangement, and leaned on relative to second cross beam 3
It is bordering on the 3rd crossbeam 4 being connected between two side girders 1 of vehicle head side arrangement.Second cross beam 3 with
Spacing is set between first crossbeam 1, meanwhile, also spacing is set between the 3rd crossbeam 4 and second cross beam 3.
The present embodiment middle cross beam component also includes extending along the length direction of vehicle, by second cross beam 3 and the
First longeron group of three crossbeams 4 connection, and is connected on the 3rd crossbeam 4, and from the 3rd crossbeam 4 to car
Second longeron group of cephalad direction extension.As shown in fig. 1, the first longeron group specifically includes two connections
Be arranged side by side first point of longeron 5 between the crossbeam 4 of second cross beam 3 and the 3rd, the second longeron group then has
Body includes second point of longeron 6 that two companies being connected on the 3rd crossbeam 4 are arranged side by side.
Each first point of longeron 5 and each second point of longeron in the present embodiment in the first longeron group and the second longeron group
6 correspond and are located along the same line, and thus can ensure that the impact force after vehicle in Floor frame structure is passed
One inertia of power passage, and ensure the reliability of impact force transmission.As shown in fig. 1, in the present embodiment,
Because the region between first crossbeam 2 and second cross beam 3 is not the main load-bearing position on vehicle, thus except two
Outside the longeron 1 of side, other beam bodies are not connected between first crossbeam 2 and second cross beam 3, thus can be had
Beneficial to the lightweight of vehicle structure.The first longeron group is also by the distance between two side girders 1 etc. in the present embodiment
Separating distance, namely two first point of longerons 5 are equal apart from the distance between the longeron 1 of respective side, by
This may be such that the arrangement of the first longeron group and the second longeron group between two side girders 1 is more regular, to be lifted
The stability of structure.
The length of first point of longeron 5 and second point of longeron 6 is also equal in the present embodiment, and makes in foregoing
On the basis of one longeron group is equal with the distance between the longeron 1 of both sides, the first longeron group in the present embodiment
The region homalographic that the longeron 1 of both sides and the crossbeam 4 of second cross beam 3 and the 3rd enclose composition is separated, namely
Composition is enclosed between two first point of longerons 5 and the longeron 1 of both sides, and between two first point of longerons 5
Area it is equal, thus can further improve the systematicness that the first longeron group is arranged in frame structure, and
Improve the overall stability of frame structure.
On the basis of frame structure structural strength is ensured, to lift it and impact force being delayed in vehicle collision
The tie point of second point of crossbeam 4 of longeron 6 and the 3rd in assimilation effect, the present embodiment is rushed, with first point of longeron
5 and the 3rd crossbeam 4 tie point, be also staggered on the 3rd crossbeam 4.This is staggered namely first
The tie point of point crossbeam 4 of longeron 5 and the 3rd, and second point of crossbeam 4 of longeron 6 and the 3rd tie point edge
Vehicle-height direction is arranged at intervals, without on the same straight line arranged along vehicle lengthwise direction.Pass through
Being staggered between two connections, can be by two tie points at the 3rd crossbeam 4 in vehicle collision
Relative motion and crumple energy-absorbing, to improve the snubber to impact force.
In the present embodiment as shown in fig. 1, the longeron 1 of both sides because of the connection with second cross beam 3 including splitting
First longeron 11 and second longeron 12 in the both sides of second cross beam 3, the 3rd crossbeam 4 are connected to two
Between second longeron 12 of side, and the 3rd crossbeam 4 is also connected to the middle part of second longeron 12 of both sides,
Thus can make that the crossbeam 4 of second cross beam 3 and the 3rd arranges in vehicle lengthwise direction is more uniform, so as to
So that overall uniform force at the crossbeam 4 of second cross beam 3 and the 3rd, to avoid the localized mode for influenceing frame structure
State.
In the present embodiment for improve frame structure structural strength, longeron 1, first crossbeam 2, second cross beam 3,
3rd crossbeam 4, and one or more of first point of longeron 5 and second point of longeron 6 are also transversal mask
There is the hollow structure of cavity, ensure that the structure of each girder construction itself is strong the characteristics of with using hollow structure beam body
Degree, and then ensure the overall structural strength of frame structure.
Floor frame structure between each crossbeam and the longeron of longeron group and both sides 1 by connecting networking after this vehicle
Shape structure, it is ensured that the structural strength and reliability of frame structure at rear floor, it is horizontal in second by longeron group
Connection between the crossbeam 4 of beam 3 and the 3rd, can lift the rigidity of the crossbeam 4 of second cross beam 3 and the 3rd, to carry
Its high flexing resistance, and correspond and be located along the same line by making first point of longeron 5 and second point of longeron 6,
Also an inertia of the body force transferring passage in collision is ensure that, the reliability of power transmission is effectively ensured, so as to
Lift the Integral modes on floor after vehicle.
Embodiment two
The present embodiment is related to a kind of vehicle body, and floor after the vehicle as described in embodiment one is equiped with the vehicle body
Frame structure.Meanwhile, the present embodiment is directed to a kind of vehicle, and the vehicle has vehicle body as described above.This
The vehicle body and vehicle of embodiment, can be true by using Floor frame structure after the vehicle as described in embodiment one
Protect the structural strength at floor after vehicle, it is ensured that the power transmission reliability after during vehicle collision at floor, and energy
Integral modes enough after lifting vehicle at floor.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in this hair
Within bright spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in this hair
Within bright protection domain.
