Description
Technical field
This utility model belongs to automobile body-in-white technical field, and in particular to a kind of body in white threshold.
Background technology
Body in white doorsill structure, as shown in figure 1, mainly being added by threshold internal plate 3a, threshold that are welded on side-wall outer-plate 1a
Strong plate 2a compositions, in prior art, side-wall outer-plate 1a extends to threshold lower edge (threshold reinforcing plate 2a lower end), forms full bag
There is following defect in the body in white threshold of formula structure, this kind of form：1) materials and tare of side-wall outer-plate 1a, be increased；
2) side-wall outer-plate 1a mould punching strokes, are increased, causes production efficiency relatively low；3), the threshold section structure easily forms narrow
Narrow slot, causes electrophoresis bad, increases the risk of threshold position corrosion.
Utility model content
The purpose of this utility model is to provide a kind of body in white threshold, can reduce the materials of side-wall outer-plate, realizes white car
The light-weight design of body.
For achieving the above object, the technical scheme adopted by this utility model is：A kind of body in white threshold, including door
Sill inner panel, threshold reinforcing plate and side-wall outer-plate, the top and bottom of threshold reinforcing plate are vertical section, and respectively with threshold internal plate
Weld to form hollow internal layer threshold in top and bottom；The threshold reinforcing plate lower end is by being inclined upwardly and away from threshold
The seam turn section that inner panel direction extends is connected with vertical seam section in parallel；The side-wall outer-plate is with threshold reinforcing plate
Upper end is beginning mouth, is welded in the threshold reinforcing plate as seam with seam section and forms hollow outer layer threshold.
Preferably, the threshold reinforcing plate upper end by towards side-wall outer-plate direction carry out successively at least 3 times turnover and to
The ladder section of lower extension is connected with the seam section.
Preferably, the threshold internal plate lower end passes through the lower end for being inclined upwardly and extending away from threshold reinforcing plate direction
Turn section is connected with and upwardly extends and the curved section with some fluctuatings, and the curved section is by being inclined upwardly and adding towards threshold
The upper end turn section that strong plate direction extends is connected with the threshold reinforcing plate upper end.
This utility model has the advantages that：In prior art, the seam of side-wall outer-plate is in threshold reinforcing plate lower end,
So that side-wall outer-plate material quantity in Z-direction size is larger.This utility model is by the seam above threshold reinforcing plate lower end
Section carries out welding seam to side-wall outer-plate so that the seam position of side-wall outer-plate in the Z-direction on move, so as to greatly reduce gusset
Materials of the outside plate in Z-direction, alleviate the weight of body in white.Correspondence position in threshold reinforcing plate in prior art and threshold internal plate
Become ladder section and curved section at the straightway put, the cross-sectional area of internal layer threshold can be increased, so as to strengthen the strong of threshold
Degree, and as the X of threshold reinforcing plate and the vehicle body of threshold internal plate is less than side-wall outer-plate to size (longitudinal length), even if increasing
The cross-sectional area of big internal layer threshold increased its materials, also can guarantee that the overall weight of body in white threshold is reduced.
Description of the drawings
Fig. 1 is the sectional drawing of body in white threshold in prior art；
Fig. 2 is the structural representation of body in white threshold in specific embodiment；
Fig. 3 is the A-A sectional drawings of body in white threshold in Fig. 2.
Specific embodiment
As shown in Figure 2 to Figure 3, a kind of body in white threshold, including threshold internal plate 3, threshold reinforcing plate 2 and side-wall outer-plate 1,
The top and bottom of threshold reinforcing plate 2 are vertical section, and weld with the top and bottom of threshold internal plate 3 respectively and form hollow
Internal layer threshold；Transferred by the seam being inclined upwardly and extend away from 3 direction of threshold internal plate 2 lower end of threshold reinforcing plate
Section 21 is connected with vertical seam section 22 in parallel；The side-wall outer-plate 1 with 2 upper end of threshold reinforcing plate as beginning mouth, with only
Mouth section 22 is welded in the threshold reinforcing plate 2 for seam and forms hollow outer layer threshold.
Internal layer threshold is the main stressed member of body in white threshold, the position easily trampled by turnover in-car, therefore required
Ensure internal layer threshold intensity, it is preferred that 2 upper end of threshold reinforcing plate by towards 1 direction of side-wall outer-plate carry out successively to
The ladder section 23 transferred and extend downwardly for few 3 times is connected with the seam section 22.3 lower end of the threshold internal plate is by being inclined upwardly
And the lower end turn section 31 extended away from 2 direction of threshold reinforcing plate is connected with and upwardly extends and the curve with some fluctuatings
Section 33, the curved section 33 pass through the upper end turn section 32 for being inclined upwardly and extending towards 2 direction of threshold reinforcing plate and the door
2 upper end of sill reinforcing plate connects.The curved section 33 of the ladder section 23 and threshold internal plate 3 of threshold reinforcing plate 2 all causes internal layer threshold whole
Body is expanded outwardly, so that its cross-sectional area increases, improves intensity.
Preferably, 1 lower end of the side-wall outer-plate extends to seam section 22 and carries out seam with the junction of seam turn section 21.
Be conducive to extending the seam length of outer layer threshold, improve welding fastness.
This utility model is only welded by the 22 pairs of side-wall outer-plates 1 of seam section above 2 lower end of threshold reinforcing plate
Mouthful so that the seam position of side-wall outer-plate 1 in the Z-direction on move, so as to greatly reduce materials of the side-wall outer-plate 1 in Z-direction, subtract
The light weight of body in white.As shown in figure 1, in prior art in threshold reinforcing plate 2a and threshold internal plate 3a correspondence position straight line
Become 33 sections of ladder section 23 as shown in Figure 3 and curve at section, the cross-sectional area of internal layer threshold can be increased, so as to strengthen door
The intensity of sill, and as threshold reinforcing plate 2 and threshold internal plate 3 are less than outside gusset to size (longitudinal length) in the X of vehicle body
Plate 1, even if the cross-sectional area of increase internal layer threshold increased its materials, also can guarantee that the overall weight drop of body in white threshold
It is low.
