Description
Technical field
The present invention relates to body of a motor car field, more particularly to a kind of B posts top connection structure.
Background technology
As shown in Figures 1 to 6, B posts top connection is that the important bridging arrangement of vehicle body, usually inner panel and outside plate constitute structure chamber
Body, skeleton enhancing structure rigidity and intensity are used as by reinforcing plate, and the quality of joint stiffness/intensity directly affects biasing and touches peace
Full performance, vehicle torsional rigidity and doorframe opening rigidity, this structure generally include side-wall outer-plate, A posts upper reinforcing plate, B posts and strengthen
Plate, roof side rail inner panel and B post inner panels；
A posts upper reinforcing plate and B post upper reinforcing plates lap-joint's welding edge make sawtooth knot symmetrical above and below in order to avoid four layers of weldering
, so can there is certain stress concentration in structure, and lap width is increased, and increases blank size in indentation, there；
Due to that cannot weld, cavity is used as segmented version, and rigidity is discontinuous for A/B column reinforcement plates lap-joint.
The content of the invention
In order to solve the problems of the prior art, the invention provides a kind of B posts top connection structure.
The invention provides a kind of B posts top connection structure, including side-wall outer-plate, A posts upper reinforcing plate, B column reinforcement plates and on
Side bar inner panel, the A posts upper reinforcing plate and the B column reinforcement plates are located between the side-wall outer-plate and the roof side rail inner panel,
Described A posts upper reinforcing plate one end overlaps with described B column reinforcement plates one end and the A posts upper reinforcing plate bottom of lap-joint is provided with
First breach, the B column reinforcement plates top of lap-joint are provided with the second breach, the side-wall outer-plate top, A posts upper reinforcing plate and
Roof side rail inner panel top overlaps, and the side-wall outer-plate bottom, B column reinforcement plates and roof side rail inner panel lower are overlapped on one
Rise.
As a further improvement on the present invention, the B column reinforcement plates are identical with the type face of the A posts upper reinforcing plate and take
The place of connecing is additionally provided with glue-line.
As a further improvement on the present invention, the B post top connections structure also include B post inner panels, the B posts inner panel top with
The roof side rail inner panel lower overlap joint, the B posts inner panel is provided with fillet clinch and the fillet clinch is provided with two layers of solder joint
And three layers of solder joint.
The beneficial effects of the invention are as follows：Set in the first breach of A post upper reinforcing plates bottom setting, on B column reinforcement plates top
Second breach, so can not only avoid four layers of weldering but also its overlap joint breach is asymmetric setting, reduce the number of overlap joint breach
Amount, reduces the stress concentration of indentation, there, also, B column reinforcement plates are identical with the type face of A post upper reinforcing plates and lap-joint also sets
There is glue-line, its B column reinforcement plate is bonded together with A post upper reinforcing plates, increased its rigidity continuity.

Specific embodiment
1- side-wall outer-plate 2-A post upper reinforcing plate 3-B column reinforcement plate 4- roof side rail inner panel 5-B post inner panels 21- first lacks
Mouth 31- the second breach 7- glue-lines bis- layers of 8-, tri- layers of solder joint 9- solder joints.
As shown in Fig. 7 to Figure 11, strengthen the invention discloses a kind of B posts top connection structure, including on side-wall outer-plate 1, A posts
Plate 2, B column reinforcement plates 3 and roof side rail inner panel 4, the A posts upper reinforcing plate 2 and the B column reinforcement plates 3 are located at the side-wall outer-plate 1
Between the roof side rail inner panel 4, described one end of A posts upper reinforcing plate 2 overlaps with described one end of B column reinforcement plates 3 and lap-joint
The top of B column reinforcement plates 3 that the bottom of A posts upper reinforcing plate 2 is provided with the first breach 21, lap-joint is provided with the second breach 31,
The top of the side-wall outer-plate 1, A posts upper reinforcing plate 2 and the top of roof side rail inner panel 4 overlap, the bottom of the side-wall outer-plate 1, B
Column reinforcement plate 3 and the bottom of roof side rail inner panel 4 overlap, by the bottom gap of A posts upper reinforcing plate 2, the top of B column reinforcement plates 3
Gap carries out overlap joint and avoids four layers of weldering, makes overlap joint breach for asymmetric setting, and effectively reduces overlap joint breach quantity, so may be used
To reduce the stress concentration of indentation, there, the problem of Cracking that B post top connection stress concentrations are caused is solved, but also A can be shortened
The lap width of post upper reinforcing plate 2 and B column reinforcement plates 3, reduces blank size, saves material cost.
The B column reinforcement plates 3 are identical with the type face of the A posts upper reinforcing plate 2 and lap-joint is additionally provided with glue-line 7, and B posts add
Strong plate 3 is fitted with the type face of A posts upper reinforcing plate 2, is attached with structure glue, increased rigidity continuity, improves B post top connections
Rigidity, so as to improve vehicle body integral rigidity.
The B post top connections structure also includes B posts inner panel 5, and the top of B posts inner panel 5 is taken with the bottom of roof side rail inner panel 4
Connect, the B posts inner panel 5 is provided with fillet clinch and the fillet clinch is provided with two layers of solder joint and three layers of solder joint, it is to avoid circle
Four layers of solder joint at angle, so not only reduce the risk of sealing-off, but also the setting of beam inner panel 4 need not be taken with fillet on top
The protrusion overlap edge of socket part adaptation, saves material, and the structure also shortens the width of B posts inner panel 5, reduces blank size drop
Low cost.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should be all considered as belonging to of the invention
Protection domain.
