The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model consists of outside plate, inner panel and compound type brace panel for traditional sedan B-post of prior art, and the many and higher problem of productive costs of number of parts, provides a kind of center body pillar structure.
As shown in Figures 2 and 3, a kind of center body pillar structure that the utility model embodiment provides, comprise side-wall outer-plate 1 and the B post body 12 of being located at side-wall outer-plate 1 inner side, described B post body 12 is one-body molded by hydraulic pressure technique, the medial surface of described B post body 12 is provided with hinge mounting hole 13 and wire harness passing-hole 14, in described hinge mounting hole 13, have two, described wire harness passing-hole 14 is located between two described hinge mounting hole 13.
As shown in Figure 4 and Figure 5, the both sides of described B post body 12 are respectively equipped with flange 17, and described flange 17 adopts spot-welding technology welding fabrication with door opening 16 edges of both sides.The bottom position of described B post body 12 is also provided with welding process hole 15 in order to weld mutually with side-wall outer-plate 1 inner side.
