Abstract
The invention discloses an automobile body in white. The automobile body in white comprises a longitudinally-closed frame structure, the frame structure is arranged in the middle of a body in white passenger cab, and the parts of the frame structure are mutually connected into a closed hoop. The frame structure comprises a roof beam, a side wall B column, a threshold, a floor beam, a middle passage and the like, wherein the roof beam is horizontally arranged on the top of the body in white. The automobile body in white can form a closed structure by adjusting the position of the beam and combining with the side wall B column, thereby effectively improving the torsional rigidity of the automobile body.
Description
Technical field
The invention belongs to auto body manufacturing technology field, specifically, relate to a kind of automobile body in white.
Background technology
At present, in auto body manufacturing technology field, more and more higher for the requirement of automobile body-in-white integral rigidity.Rigidity is the key factor that affects vehicle body NVH performance, and the quality of body structure is one of key factor affecting body stiffness.Along with user vehicle is more and more paid close attention to the NVH performance of automobile, the integral structure rigidity that how to improve body in white has become a major issue of the required consideration of automotive development stage engineer.For body in white rigidity, roof panel cross member and floor beam are key factors that affects its size.
In prior art, a lot of auto vendors are in the time carrying out body in white design, and the location comparison of automobile body-in-white roof panel cross member and floor beam is random, has active technique problem:
1,, in prior art, carrying out body in white when design, on automobile body-in-white top cover, because crossbeam is more, and the power of each crossbeam, size are all indefinite, can not well bring into play the effect that crossbeam should play.
2, in prior art, because crossbeam is more, and arrange unreasonablely, in the situation that substantially not changing original intensity, cause manufacturing cost greatly to promote.
Summary of the invention
Technical matters to be solved by this invention is, in prior art, in the time carrying out body in white design, on automobile body-in-white top cover, because crossbeam is more, and the power of each crossbeam, size are all indefinite, can not well bring into play the effect that crossbeam should play; Because crossbeam is more, and arrange unreasonablely, in the situation that substantially not changing original intensity, cause the technical matterss such as manufacturing cost promotes greatly, and a kind of automobile body in white is provided.
Technical scheme provided by the present invention is, a kind of automobile body in white, and described body in white comprises the framed structure of longitudinal sealing, described framed structure is arranged in the middle part of described body in white passenger compartment, between the each parts of described framed structure, interconnects, and forms closed loop.
Described framed structure comprises roof panel cross member, gusset B post, threshold, floor beam and middle passage etc., and described roof panel cross member lateral arrangement is at described body in white top.
Described roof panel cross member two ends connect respectively gusset B post, and described gusset B post connects described threshold.
Described floor beam connects described middle passage, and described middle passage is arranged in described floor beam two ends and middle part.
Described threshold connects described middle passage.
Described roof panel cross member, gusset B post, threshold, floor beam and middle passage form the framework of a sealing by welding, increase integral rigidity.
Described roof panel cross member, gusset B post, threshold, floor beam and middle passage in described framed structure at the center line of Y-direction in one plane.Described Y-direction is the vertical direction perpendicular to described all parts self arranged direction, and if roof panel cross member is that basic horizontal is arranged, its Y-direction is perpendicular to vertical direction of horizontal direction etc.
Adopt technical scheme provided by the present invention, can effectively solve in prior art, in the time carrying out body in white design, on automobile body-in-white top cover, because crossbeam is more, and the power of each crossbeam, size are all indefinite, can not well bring into play the effect that crossbeam should play; Because crossbeam is more, and arrange unreasonable, in the situation that substantially not changing original intensity, cause the technical matterss such as manufacturing cost promotes greatly, the present invention can, by adjusting the position of crossbeam, form the structure of a sealing in conjunction with body side wall B post, energy actv. improves the torsional stiffness of vehicle body.
Accompanying drawing explanation
By reference to the accompanying drawings, the present invention is further illustrated:
Fig. 1 is structural representation of the present invention;
Wherein, 1 is roof panel cross member; 2 is gusset B post; 3 is middle passage; 4 is threshold; 5 is floor beam.
The specific embodiment
As shown in Figure 1, a kind of automobile body in white of the present invention, described body in white comprises the framed structure of longitudinal sealing, described framed structure is arranged in the middle part of described body in white passenger compartment, between the each parts of described framed structure, interconnects, and forms closed loop.Described framed structure comprises roof panel cross member 1, gusset B post 2, threshold 4, floor beam 5 and middle passage 3 etc., and described roof panel cross member 1 lateral arrangement is at described body in white top.Described roof panel cross member 1 two ends connect respectively gusset B post 2, and described gusset B post 2 connects described threshold 4.Described floor beam 5 connects described middle passage 3, and described middle passage 3 is arranged in described floor beam 5 two ends and middle part.Described threshold 4 connects described middle passage 3.Described roof panel cross member 1, gusset B post 2, threshold 4, floor beam 5 and middle passage 3 form the framework of a sealing by welding, increase integral rigidity.Described roof panel cross member 1, gusset B post 2, threshold 4, floor beam 5 and middle passage 3 in described framed structure at the center line of Y-direction in one plane.Described Y-direction is the vertical direction perpendicular to described all parts self arranged direction, and if roof panel cross member 1 is that basic horizontal is arranged, its Y-direction is perpendicular to vertical direction of horizontal direction etc.
The present invention relates to a kind of body structure, roof panel cross member 1, gusset B post 2, threshold 4, floor beam 5 and middle passage 3 are coupled together and make it form the framed structure of a sealing, make the center line of its Y-direction in one plane.For multiple crossbeams on top cover, it is as far as possible large and strong that the beam structure between gusset B post 2 should design.By analysis verification, if lack crossbeam on the top cover between left and right gusset B post 2 and floor, can increase body torsional rigdity 10% left and right after increasing this crossbeam; If top cover and floor entablatrance Y-direction center line and B post Y-direction center line are not in one plane, can improve body torsional rigdity 4% left and right by optimizing and revising after making its center line in one plane.And this kind of structure can improve automobile side crash ability, reduce the displacement after the side impact of B post.
