Description

Vehicle floor skeleton additional strengthening
Technical field
The utility model relates to a kind of vehicle floor skeleton additional strengthening.
Background technology
Vehicle floor skeleton additional strengthening widespread is in car, and as the additional strengthening of longitudinal floor beam and back floor crossmember, this structure is the pipeline of head-on crash impulsive force behind the vehicle body.The additional strengthening of this position in the past; a kind of vehicle floor skeleton additional strengthening as shown in Figure 1; it adopts hollow stirrup 10; and one of stirrup is adopted the structure of flattening; and attachment point is flattening part 20; the stirrup other end is fixed on the stirrup adapter plate 30 by carbon-dioxide arc welding; such additional strengthening weight is heavier; complex structure; and because employing is that hollow stirrup is strengthened; the moment of flexure that hollow stirrup itself can bear is big inadequately, causes the single-piece stiffening effect not good.
The utility model content
Problem to be solved in the utility model is at the not good problem of additional strengthening stiffening effect of longitudinal floor beam in the prior art and back floor crossmember, and a kind of simple in structure, vehicle floor skeleton additional strengthening that stiffening effect is good is provided.
The utility model is achieved through the following technical solutions: a kind of vehicle floor skeleton additional strengthening, comprise first longeron and back floor crossmember, one end and first longeron of described back floor crossmember are affixed, also comprise first brace panel, the outside of described first brace panel has turnup structure, one end of described first brace panel is fixed on the floor crossmember of back, and the other end is fixed on first longeron.
According to floor frame additional strengthening of the present utility model, be provided with turnup structure in the outside of first brace panel, thereby can increase the moment of flexure that first brace panel self is born well, thereby improve the intensity of whole vehicle floor skeleton additional strengthening.
Description of drawings
Fig. 1 is the scheme drawing of the floor frame additional strengthening of prior art;
Fig. 2 is the scheme drawing of an embodiment floor frame of the utility model additional strengthening;
Fig. 3 is the structural representation of embodiment first brace panel of the utility model.
The specific embodiment
Below, in conjunction with the accompanying drawings, the utility model is described in detail.
As shown in Figure 2 to Figure 3, comprise first longeron 1 and back floor crossmember 2 according to vehicle floor skeleton additional strengthening of the present utility model, one end and first longeron 1 of described back floor crossmember 2 are affixed, also comprise first brace panel 3, the outside of described first brace panel 3 has turnup structure 31, one end of described first brace panel 3 is fixed on the floor crossmember 2 of back, and the other end is fixed on first longeron 1.One end and first longeron 1 of described back floor crossmember 2 are fixedly connected by welding.In the present embodiment, have four mounting holes 32 on described first brace panel 3, be provided with two bolts hole with described four mounting holes 32 two last cooresponding positions wherein on first longeron 1, also be provided with two bolts hole with two other mounting hole 32 cooresponding positions on the back floor crossmember 2, four bolts 4 pass these four mounting holes 32 and described four bolts hole with an end of described first brace panel 3 be fixed on first longeron 1, the other end is fixed on first longeron 1.Turnup structure 31 on first brace panel 3 can increase the moment of flexure that first brace panel self is born well, thereby improves the intensity of whole vehicle floor skeleton additional strengthening.Compared to existing technology, of the present utility model simple in structure, and in light weight, cost is low, and processing technology is simple, is easy to loading and unloading.
In the present embodiment, as shown in Figure 3, the described first brace panel forming V-shape, and have two ends, turnup structure is formed on the corner location at two ends, that end that described first brace panel links to each other with first longeron has a mounting hole, described corner location place also has a mounting hole, two other mounting hole is arranged on that end that described first brace panel links to each other with the back floor crossmember, stress when mounting hole layout like this can guarantee the installation of first brace panel disperses, the corner location of described first brace panel is higher than the other parts (by the structures shape of first longeron) of first brace panel, make the lower surface of described first brace panel and the upper surface relevant position of first longeron and back floor crossmember fit, to prevent first brace panel, cause the fracture of first brace panel because self the distortion power that unsettled setting causes is excessive.
As preferentially, present embodiment also comprises second longeron and second brace panel, and described second brace panel is identical with first brace panel, 3 structures, and described second brace panel, one end is fixed on the floor crossmember 2 of back, and the other end is fixed on second longeron.
In the present embodiment, the described second brace panel forming V-shape, and have two ends, turnup structure is formed on the corner location at two ends, that end that described second brace panel links to each other with second longeron has a mounting hole, described corner location place also has a mounting hole, two other mounting hole is arranged on that end that described second brace panel links to each other with the back floor crossmember, stress when mounting hole layout like this can guarantee the installation of second brace panel disperses, the corner location height of described second brace panel is higher than the height (by the structures shape of second longeron) of the other parts of second brace panel, make the lower surface of described second brace panel and the upper surface relevant position of second longeron and back floor crossmember fit, can prevent second brace panel because self the distortion power that unsettled setting causes is excessive, cause the fracture of second brace panel.
In the present embodiment, described first longeron 1 comprises integrally formed straight beam 11 and bending beam 12, described straight beam 11 is along the longitudinal extension of vehicle body, described bending beam 12 is from an end of the straight beam outer lateral buckling to vehicle body, one end of described back floor crossmember 2 is connected the joint position of described bending beam 12 and described straight beam 11, and extend along the direction of bending beam 11 and back floor crossmember 2 respectively at the two ends of described first brace panel 1.
Described second longeron is symmetrical arranged along the vehicle body center line and first longeron, the other end of described back floor crossmember is connected the bending beam of described second longeron and the joint position of straight beam, extend along the direction of bending beam and back floor crossmember respectively at the two ends of described second brace panel, plays booster action better.
In the vehicle floor skeleton, the first above-mentioned longeron can be left longeron or right vertical beam, and second longeron can be left longeron or right vertical beam also, that is to say when first longeron is left longeron, and second longeron is a right vertical beam; When first longeron was right vertical beam, second longeron was left longeron.The first above-mentioned longeron and second longeron are the beams along the symmetrically arranged same structure of center line of vehicle body, the two ends of back floor crossmember are connected to the straight beam of left longeron and right vertical beam and the position that the bending beam joins, first brace panel is identical with the second brace panel structure, and second brace panel in fact also is that first brace panel is symmetrically arranged along the vehicle body center line.Fig. 2 is the connection diagram of first longeron, first brace panel, back floor crossmember, because second longeron, second brace panel, back floor crossmember is along vehicle body center line and symmetrically arranged, no longer do the connection diagram of second longeron, second brace panel, back floor crossmember.Above-mentioned floor frame additional strengthening can play good booster action to the rear portion of vehicle body, when rear portion central collision or side impact take place vehicle, can protect vehicle that serious deformation does not take place well.
