Description
Technical field
This utility model relates to the body structure of automobile, more particularly, to a kind of front floor of automobile body being applicable to automobile.
Background technology
Along with auto industry and scientific and technological developing rapidly, people are more and more higher to the requirement of Automobile Design, particularly vapour
The security performance of car and the influence factor of this conflict of lightweight, increasingly paid attention to.Front floor of automobile body is composition vehicle body
One of bottom important component, is mainly used in carrying front-row seats and bearing the weight of occupant；Car body, in moving process, bears vapour
Load that car produces, vibrate, impact and moment of torsion；And car body is when being collided, conduct and discharge its impact force being subject to.Vehicle body
Front floor should meet crashworthiness requirement, i.e. front floor of automobile body should keep enough rigidity and intensity, and major way is for passing through
The material selecting high intensity makes or increases the thickness of the selection of material, to increase the load-carrying ability that front floor of automobile body bears.But,
The front floor of automobile body that aforesaid way makes cannot meet light-weighted requirement.
Fig. 1 is the schematic diagram on the front floor of existing body of a motor car.Fig. 2 is the fractionation on the front floor of the body of a motor car shown in Fig. 1
Schematic diagram.Fig. 3 is the A-A sectional view on the front floor of the body of a motor car shown in Fig. 1.As shown in Figure 1,2 and 3, the front floor of body of a motor car
For about axis symmetrical structure.Before two pieces slab 1 connected by middle passage symmetry, middle passage by middle Channel front end 6, in
