Abstract
The invention discloses an automotive body center post with a strengthening structure, which comprises a side wall outer plate, a center post strengthening plate and a center post inner plate that are sequentially welded, wherein a safety belt fixing and strengthening plate and a safety belt nut plate are sequentially welded on the center post strengthening plate and are formed into a cavity section after welded through rolled edge laps at two sides; the safety belt fixing and strengthening plate is welded in a groove at the upper half part of the center post strengthening plate, the safety belt nut plate is welded and covered from the middle to the upper part of the safety belt fixing and strengthening plate, and a safety belt installing screw hole is arranged on the safety belt nut plate. The invention greatly strengthens the strength and the rigidity of the upper half part of the automotive body center post; the middle upper part of the center post is not easy to deform in collision at sides and enables the impact force to transmit to other energy absorbing parts of an automotive body, thereby ensuring that the impact force is dispersed and reduced and effectively protecting the head and the shoulder of the passenger at the front row.
Description
Technical field
The present invention relates to the body structure of automobile, specifically, relate to a kind of auto body center pillar that has additional strengthening.
Background technology
The vehicle body of general car has three columns, be followed successively by front pillar (A post), center pillar (B post), rear pillar (C post) from front to back, column is except playing a supportive role, also play the effect of doorframe, center pillar is the supported cart top cover not only, also will bear the supporting power of forward and backward car door, thereby center pillar will have certain intensity and rigidity, simultaneously on center pillar, also to install some add-on partss additional, such as front-seat safety strap.Existing center pillar generally comprises integrally welded successively side-wall outer-plate, middle column reinforcement plate and center pillar inner panel, is welded with the safety strap nutplate at middle column reinforcement plate near on the side plate face of center pillar inner panel.Be welded with nut 3a on the safety strap nutplate 3, form the belt installation screw, the length and the width dimensions of safety strap nutplate 3 are close, and are used to install safety strap.When the side of automobile suffers strong collision, because bearing surface less buffer area in side is little, the center pillar easy deformation of existing structure, thus impact, press and bump against the passenger, particularly be easy to hurt the head and the shoulder of front-row occupant.
Summary of the invention
Technical matters to be solved by this invention is: a kind of auto body center pillar with additional strengthening is provided, and it has sufficiently high strength and stiffness, and the middle and upper part of center pillar is not yielding when making side collision, can effectively protect the head and the shoulder of front-row occupant.
Technical scheme of the present invention is as follows: a kind of auto body center pillar with additional strengthening, comprise the side-wall outer-plate of welding successively, middle column reinforcement plate and center pillar inner panel, described side-wall outer-plate and center pillar inner panel are encircled into die cavity, column reinforcement plate is positioned at this die cavity in described, column reinforcement plate is provided with the longitudinal fluting to side-wall outer-plate direction depression in this, its key is, in described, also be welded with safety strap fixedly brace panel and safety strap nutplate on the column reinforcement plate successively, described safety strap fixedly brace panel overlaps postwelding mutually with the flange that the safety strap nutplate is passed through both sides, is formed with the die cavity section; Described safety strap fixedly brace panel be welded on described in the groove of column reinforcement plate first half position, described safety strap nutplate welding covers safety strap and fixedly the middle part of brace panel is provided with the belt installation screw to top on this safety strap nutplate.
The present invention adds fixedly brace panel of safety strap of weldering in the middle and upper part of middle column reinforcement plate; the middle and upper part of center pillar is strengthened; fixedly reinforced by the safety strap nutplate of lengthening again the middle and upper part of brace panel at safety strap; also include the die cavity section after two reinforcement welding; when automobile side is subjected to suffering strong collision; owing to strengthened by the die cavity section of two brace panels and formation thereof in the middle and upper part of center pillar; first position of center pillar is difficult for distortion; simultaneously impact is delivered to other energy-absorbing parts on the vehicle body; make impact obtain disperseing; reduce; and second position of center pillar also can absorb by distortion; the attenuate shock energy, thus the head and the shoulder of front-row occupant effectively protected.
In order to strengthen two brace panels, the described safety strap fixedly thickness of slab of brace panel and safety strap nutplate is 2.5～3.5mm.Sheet material is crossed thin insufficient strength, and sheet material is blocked up, and then easy-formation and unrelieved stress are not big.
For further optimizing structure, form intensity, rigidity brace panel preferably, it also is the shape of column reinforcement plate in adapting to, the described safety strap fixedly cross-sectional plane of brace panel is concave structure, the side that comprises bottom surface and both sides, bottom surface, two sides are from top to bottom widened gradually, are provided with flange at the middle part, two sides to the edge, top, the plate face overlap joint of the groove notch both sides of two flange and described middle column reinforcement plate.
For ease of welding, fixedly brace panel and middle column reinforcement plate can firm welding to make safety strap, in such scheme, the top of described bottom surface and middle part are respectively equipped with outstanding upward welding boss and the middle welding boss of column reinforcement plate in described, are provided with to the outstanding following welding boss of described groove in the bottom of two described sides.Each pressure-formed welding boss also can make safety strap fixedly brace panel be further strengthened.
Further, described safety strap fixedly the bottom surface lower press of brace panel the flute profile reinforced rib is arranged.
For ease of with the fixing suitable mutually and overlap joint of brace panel shape of safety strap, the both sides of described safety strap nutplate are provided with flange, this flange and safety strap be the suitable applying of two side flangings of brace panel fixedly.
For safety strap can be installed, the safety strap nutplate is strengthened by the punching press distortion, the middle part of described safety strap nutplate is provided with rectangular boss with holes, is welded with the nut coaxial with described hole at the lower surface of this boss.
As further reinforcement design, the upper and lower of described safety strap nutplate is suppressed with strip groove respectively.
The invention has the beneficial effects as follows: the strength and stiffness of having strengthened first position of auto body center pillar greatly; the middle and upper part of center pillar is not yielding during side collision; impact can be delivered to other energy-absorbing parts on the vehicle body; make impact obtain disperseing, reducing, thereby effectively protect the head and the shoulder of front-row occupant.
