Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automobile door sill additional strengthening.
Background technology
Life is fine, and people's life for once, so " safety " just becomes human eternally immutable theme.Along with the development of society, the popularizing of automobile, traffic accident is threatening people's safety constantly; Can trouble-saving generation be naturally; But generally, accident has often just taken place inadvertently, and formed threat also becomes very important so the reduction accident is to people's life.And it is still very poor for the ability of prior art automobile door sill opposing side impact.
The anti-side impact capability improving of automobile door sill space is still very big; People have carried out long term studies to this; And obtained certain achievement; A kind of automobile side crash additional strengthening of the disclosed patent of Chinese patent document [Granted publication number: CN2813409Y] for example, it is that threshold inner panel and inboard, the formed space of side-wall inner-plate assembly add two sheet spare brace panels, forms an approximate box body.Two strengthen plates two welding flange separately and threshold two faces weld, other flange shape and side-wall inner-plate shape face near.Further, on brace panel, done reinforced rib, reinforced rib is along the bodywork height direction.
Above-mentioned patent threshold intensity also has very big room for promotion, and particularly the stiffening effect at center pillar position is relatively poor during side impact, and is yielding during side impact, safety that can not actv. protection passenger.
Summary of the invention
The purpose of the utility model is the problems referred to above that exist to existing technology, and a kind of automobile door sill additional strengthening is provided, and the utility model technical matters to be solved is to improve the intensity of threshold additional strengthening.
The purpose of the utility model can realize through following technical proposal: a kind of automobile door sill additional strengthening, and threshold comprises side-wall outer-plate spare; This additional strengthening comprises the main brace panel that is positioned at the inboard strip of side-wall outer-plate spare, and the cross-sectional plane of described main brace panel is " U " shape; It is characterized in that, the opening part at described main brace panel position under the car body center pillar secondary brace panel that is connected, described secondary brace panel rising wood and the welding of car body center pillar are connected.
Main brace panel matching pair brace panel can increase substantially the intensity of threshold; Particularly secondary brace panel welding is connected on the car body center pillar; Strengthened threshold and be connected, the car body center pillar is further strengthened the intensity of threshold, like this when automobile generation side impact with the integral body of car body center pillar; Threshold just is difficult for producing distortion, passenger's safety when greatly having improved side impact.
In above-mentioned a kind of automobile door sill additional strengthening, described secondary brace panel is strip, has several on the described secondary brace panel along its vertical distribution and through stamping forming bending resistance groove.Groove can be strengthened the bend resistance ability of secondary brace panel effectively.
In above-mentioned a kind of automobile door sill additional strengthening, the two ends of described secondary brace panel all have flank, and described flank embeds in the cavity of main brace panel; Described secondary brace panel and main brace panel enclose and are configured to a bending resistance cavity.Cavity improves whole locomotive body center pillar bottom rigidity, energy delivered when absorbing side collision preferably, thereby raising passenger's safety.
In above-mentioned a kind of automobile door sill additional strengthening, described flank is connected on the inwall of main brace panel through welding.
In above-mentioned a kind of automobile door sill additional strengthening, the shape of described flank is corresponding with the cavity cross section shape of main brace panel; All have several weld nuggets between the inwall of described flank and each main brace panel.
In above-mentioned a kind of automobile door sill additional strengthening, described secondary brace panel lower edge and the welding of main brace panel.
The rising wood of secondary brace panel and center pillar welding are connected; Two flanks and lower edge are connected with main brace panel welding again; So just formed a firm cavity; The shape of flank is corresponding with cavity again and the weld nugget distribution is wide, makes the steadiness of cavity further strengthen, and lets cavity that the energy absorbing of automobile side impact is reached optimum regime.
In above-mentioned a kind of automobile door sill additional strengthening, described bending resistance cavity place is provided with stay bearing plate; Three the edge portions of described stay bearing plate and the inwall of main brace panel are fixedly connected by welding, and an edge portion and secondary brace panel are fixedly connected by welding.Stay bearing plate supports secondary brace panel and main brace panel in cavity, makes main brace panel and the more difficult distortion of secondary brace panel, and the intensity of threshold is also just higher naturally like this, and anti-collision ability is also stronger, and occupant's safety is further strengthened.
In above-mentioned a kind of automobile door sill additional strengthening, described car body center pillar comprises middle column reinforcement plate, and the lower edge of described middle column reinforcement plate is positioned at the inboard of secondary brace panel, and the lower edge and the welding of secondary brace panel rising wood of column reinforcement plate is connected in described.Let secondary brace panel and center pillar also form an integral body like this, and when automobile generation side impact, the secondary brace panel that is arranged in the outside can be resisted against on the column reinforcement plate, the weld is not easy fracture, and globality is better, and anti-collision ability is stronger.
Compared with prior art; The utility model forms an integral body to secondary brace panel and the welding of car body center pillar; Form a firm cavity that energy-absorbing effect is good again between secondary brace panel and the main brace panel; Make the intensity of whole threshold additional strengthening show very intrepidly, make the anti-side impact ability of threshold outstanding, occupant's safety has also had good guarantee during the vehicle side impact.
