The invention relates to the field of automobile body stabilizing structures, in particular to a CCB modal lifting annular structure of a non-bearing type automobile body structure, which is characterized in that a front top cross beam welding assembly, a front floor sub assembly, a left inner door ring assembly and a right inner door ring assembly respectively form the upper, lower, left and right frame edges of a first frame body annular structure; the instrument cross beam support divides the first frame annular structure into a second frame annular structure and a third frame annular structure, and the gutter channel body assembly, the instrument cross beam support, the left front wheel cover upper reinforcing beam assembly and the right front wheel cover form a fourth frame annular structure. According to the CCB modal lifting annular structure, the multi-annular structures are formed in the front portion and the middle portion of the non-bearing vehicle body, so that the rigidity of the vehicle body structure is improved, the inherent frequency of a CBB can be improved, resonance and steering wheel shaking are prevented, the NVH and safety performance of the whole vehicle are remarkably improved, and meanwhile the manufacturing cost of the whole vehicle is reduced.
本发明涉及汽车车身稳定结构领域,具体公开了一种非承载式车身结构的CCB模态提升环状结构,前顶横梁焊接总成、前地板分总成、左内门环总成和右内门环总成分别构成第一框体环状结构上下左右的框边,仪表横梁支架将第一框体环状结构分成第二框体环状结构和第三框体环状结构,流水槽本体总成与仪表横梁支架、左前轮罩上加强梁总成和右前轮罩形成第四框体环状结构。该CCB模态提升环状结构通过在非承载车身的前部、中部形成多环状结构,来提升车身结构的刚度,能提升CBB固有频率,防止共振和方向盘抖动,对整车NVH以及安全性能提升显著,同时降低整车制造成本。
