Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The schematic diagram of four-way soldering part in the B post connecting assembly that Fig. 1 provides for the utility model.The structural representation of the B post connecting assembly that Fig. 2 provides for the utility model.The schematic diagram of the welding manner of four-way soldering part and middle head piece, B post and roof rail in the B post connecting assembly that Fig. 3 provides for the utility model.The B post connecting assembly that the utility model provides can be used for the automobile of Multiple Type.
The B post connecting assembly that the utility model embodiment provides, its structural representation as shown in Figure 2, comprises middle head piece 1, B post 4, roof rail and four-way soldering part 2;
The structure of four-way soldering part 2 as shown in Figure 1, comprise the first groove 21 and the second groove 22, described first groove 21 and the second groove 22 mutually intersect and are formed through cross groove structure, and the sidewall upper limb of described first groove 21 and the second groove 22 has the kink 23 to its outer lateral buckling, an end of wherein said first groove 21 bends to its internal direction;
Wherein B post 4 and middle head piece 1 weld with the both ends of described first groove 21 respectively, and described roof rail comprises roof rail anterior 5 and roof rail rear portion 3, and described roof rail anterior 5 and roof rail rear portion 3 are welded with the both ends of described second groove 22 respectively.
In above-mentioned B post connecting assembly, head piece 1, B post 4 and roof rail (comprising roof rail anterior 5 and roof rail rear portion 3) in using four-way soldering part 2 to connect, both the generation of four layers of welding had been avoided, eliminate again the processing step offering breach, avoid the reduction of head piece 1 in causing due to the setting of breach, B post 4 and roof rail junction intensity simultaneously.Above-mentioned four-way soldering part 2 is by Sheet Metal Forming Technology manufacture, and because its structure is simple, therefore the process costs of stamped is cheap, and operation is simple.
Under normal circumstances, in four-way soldering part 2, each end shape of the first groove 21 and the second groove 22 can with to be connected in the end of head piece 1, B post 4 or roof rail match, so that weld.
Simultaneously, due in body structure, the plane that B post 4, roof rail anterior 5 and roof rail rear portion 3 are connected to form and middle head piece 1 are arranged in an angle, as shown in Figure 2, therefore as in the four-way soldering part 2 of attaching parts, one end of the first groove 21 bends to its internal direction, effectively connects B post 4 and middle head piece 1 to enable the both ends of the first groove 21.
