Utility model content
The problems referred to above that exist for automobile body side wall structure in prior art, the utility model provides a kind of automobile body side wall B column structure.
The technical solution of the utility model is:
A kind of automobile body side wall B column structure, it is characterized in that: comprise brace panel, side body top apodema in side-wall outer-plate, side-wall inner-plate, gusset B column reinforcement plate, threshold brace panel, gusset top side, described gusset B column reinforcement plate is arranged between side-wall outer-plate and side-wall inner-plate, in described threshold brace panel and gusset top side, brace panel is arranged at respectively the two ends of gusset B column reinforcement plate, and described side body top apodema is arranged at one end corresponding with brace panel in gusset top side on side-wall inner-plate.
As further improvement of the utility model, the structure of described gusset B column reinforcement plate is to have integrated the aluminium alloy compression casting structure that under Qianmen snap close installation, gusset B post, hinge is installed and front chair safety strap is installed.
As further improvement of the utility model, described gusset B column reinforcement plate is fixedly connected with the mode of brace panel in threshold brace panel, gusset top side by welding, side-wall inner-plate is fixedly connected with the mode of side body top apodema by welding, and described side-wall inner-plate is fixedly connected with the mode of side-wall outer-plate by welding with brace panel in gusset top side with threshold brace panel with side body top apodema, described gusset B column reinforcement plate.
The beneficial effects of the utility model are:
1, gusset B column reinforcement plate of the present utility model is die casting aluminium framing member, die casting structure Design freedom is high, so it has integrated hinge installation and the installation of front chair safety strap etc. under Qianmen snap close installation, gusset B post, number of parts and welding level reduce, simple in structure;
2, the utility model adopts aluminum alloy, and lightweight is obvious.According to CAE simulation analysis result, show, after adopting automobile body side wall B column structure of the present utility model, vehicle body side collision can meet safety performance requirement.
