Background technology

Continuous progress along with technology, crash survivability requirement to automobile is more and more higher, and in the collision process of automobile, body structure must have good energy-absorbing effect, simultaneously guarantee that again the occupant has enough living spaces, wherein the energy-absorbing function of automobile side structure is even more important; Under the prerequisite that guarantees collision safety, automotive light weight technology also more and more receives people's concern.

Existing automobile B-pillar reinforcement plate, usually adopt following two kinds of forms: the one, the integral structure that is formed by the steel plate punched of same even thickness, this structure fabrication is simple, can guarantee preferably overall leveling and the dimensional accuracy of part, but steel plate thickness is by the required maximum thickness design of intensity, therefore is unfavorable for the lightweight of vehicle body; The 2nd, B column reinforcement plate upper-lower section adopts the fraction block structure of steel plate by being made of welded connection of different-thickness, this structure makes moderate progress aspect body lightening, but increased quantity and the processing capacity of part, and the planeness of piece surface can't guarantee, parts size precision also can reduce.

The utility model content

The technical problems to be solved in the utility model provides a kind of automobile B-pillar reinforcement plate structure and vehicle, can promote the weight of automotive side face collision safety and reduction vehicle body, reaches the purpose of body lightening.

For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of automobile B-pillar reinforcement plate structure, comprising: the B post is strengthened outside plate, comprises epimere part and hypomere part, and the thickness of described epimere part is greater than the thickness of described hypomere part.

Wherein, described B post is strengthened the epimere part inboard of outside plate, is provided with the B post that partly is connected with the described epimere of described B post reinforcement outside plate and strengthens inner panel.

Wherein, the described epimere part of described B post reinforcement outside plate is connected with described B post reinforcement inner plate welding.

Wherein, described B post reinforcement inner panel is comprised of interconnective two high-strength plates.

Wherein, described two high-strength plates are welded to connect.

Wherein, described B post is strengthened outside plate and is adopted laser assembly solder plate to make, and has laser assembly solder seam between described epimere part and the hypomere part.

Wherein, described laser assembly solder seam is positioned at below the H point of automotive seat.

Wherein, the described epimere part of described B post reinforcement outside plate is provided with energy-absorbing muscle and the groove of projection.

Wherein, described B post is strengthened the energy-absorbing muscle that inner panel is provided with projection.

Embodiment of the present utility model provides a kind of vehicle, comprising: body structure, and aforesaid automobile B-pillar reinforcement plate structure, described automobile B-pillar reinforcement plate structure is fixed on the described body structure.

The beneficial effect of technique scheme of the present utility model is as follows:

In the such scheme, B column reinforcement plate outside plate is to be stamped to form by the laser assembly solder slab integral, laser assembly solder plate is comprised of two sections, its epimere material is thick, the hypomere material is thick thinner, mainly is that impact is born on top when collision, needs larger intensity, this design has reduced again whole weight under the requirement of satisfying intensity.B column reinforcement plate inner panel is to be welded by two high-strength plates, its position is main near near the upper hinge, connect together by welding with B column reinforcement plate outside plate, this structure can make epimere Reducing distortion when collision, to reduce B post trim panel etc. to the intrusion amount of interior of body, actv. has guaranteed occupant's living space, thereby improves the safety of car load collision.

Description of drawings
