The invention discloses a reinforcing device for improving the rigidity modal performance of an automobile body and an automobile. The device comprises a B-pillar lower inner plate, one side of the B-pillar lower inner plate is connected with an integrated door ring reinforcing plate through a reinforcing assembly, and the other side of the B-pillar lower inner plate is connected with an inner doorsill body; the reinforcing assembly comprises a fixing piece and a supporting piece, the fixing piece and the supporting piece are of an integrated structure, and the fixing piece is connected with the integrated door ring reinforcing plate. The end, away from the fixing piece, of the supporting piece abuts against the inner side of the B-column lower inner plate to support the B-column lower inner plate, so that a box type structure is formed among the inner doorsill body, the B-column lower inner plate, the integrated door ring reinforcing plate and the fixing piece. By adopting the structure to reinforce the lower doorsill of the column B, the rigidity and the connecting strength of an automobile body are effectively improved, the problems of abnormal sound, resonance and cracking of the automobile body in the driving process are solved, the riding safety of customers is improved, and compared with a traditional mode of increasing the material thickness, the structure has the advantages that the effect of improving the rigidity modal performance of the automobile body is remarkable; and the lightweight effect of the vehicle body structure is obvious.

    本发明公开了一种提升车身刚度模态性能的加强装置及汽车,装置包括B柱下内板,其一侧通过加强组件连接有一体门环加强板,另一侧连接有内门槛本体;加强组件包括固定件和支撑件,固定件和支撑件为一体结构,固定件与一体门环加强板连接;其中,支撑件远离固定件的一端抵在B柱下内板内侧,对B柱下内板支撑,以使内门槛本体、B柱下内板、一体门环加强版和固定件之间构成箱式结构。采用该结构对B柱下门槛进行加强,有效提升了车身的刚度及连接强度,减弱汽车车身在行驶过程中异响、共振和开裂的问题,提高了顾客的乘坐的安全性,与传统增加料厚的方式相比,该结构对车身刚度模态性能提升效果显著,且车身结构轻量化效果明显。
