Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to its implementation.
As shown in figure 1, the invention provides a kind of automobile B-column structure, including B posts outside plate 1 and B posts inner panel 2, B posts outside plate 1
It is that metal level by being connected to each other and carbon fibre composite layer are formed with B posts inner panel 2.This B-pillar structure by metal material with
Carbon fibre composite is combined, the characteristics of making full use of high intensity, the high-modulus of carbon fibre composite, ensure that metal
On the premise of B post mechanical properties, structure is simplified, compared to traditional B posts, local reinforcing plate can be cancelled, but also can drop
The steel plate thickness of low B posts outside plate 1 and B posts inner panel 2, instead carbon fibre composite local enhancement B posts outside plate 1, B posts inner panel 2,
So as to which construction weight is greatly lowered, lightweight is realized.
Specifically, as shown in figure 1, B posts outside plate 1 includes outside plate metal level 11 and is arranged on the surface of outside plate metal level 11
Carbon fibre composite layer 12.B posts inner panel 2 includes inner panel metal level 21 and the carbon being arranged on the surface of inner panel metal level 21 is fine
Composite layer 22 is tieed up, inner panel metal level 21 is simultaneously connected with outside plate metal level 11.Outside plate metal level 11 and inner panel metal level 21 are
It is stamping forming using Metal plate, respectively as B posts outside plate 1 and the substrate of B posts inner panel 2.
Inner panel metal level 21 is to be welded to connect with outside plate metal level 11, carbon fibre composite layer 12 and outside plate metal level 11
For bonding connection, carbon fibre composite layer 22 and inner panel metal level 21 are bonding connection.In the present embodiment, as shown in figure 1,
B posts outside plate 1 forms the B-pillar structure of inner hollow after being connected with B posts inner panel 2, it is inner chamber body 3 that it is internal, carbon fibre composite
Layer 12 is arranged at outside plate metal level 11 towards on the medial surface of inner panel metal level 21, and carbon fibre composite layer 22 is arranged at inner panel
