The invention relates to the technical field of car body-in-white hallstands, in particular to a supporting rod structure capable of improving torsional rigidity of a car body, which comprises a V-shaped main body and two inclined struts symmetrically arranged on two sides of the V-shaped main body, the inclined struts face downwards, and the V-shaped main body and the two inclined struts are integrally formed. According to the supporting rod structure, efficient utilization of materials is achieved through the topological optimization technology, the torsional rigidity of the whole vehicle is improved by more than 11%, and meanwhile the manufacturing process is simplified. According to the structure, the innovative layout of the V-shaped main body and the inclined struts is adopted, a plurality of triangular and inverted W-shaped structures are formed, and the stability and the bearing capacity are enhanced. Due to the collinear arrangement of the inclined struts and the V-shaped main body and the design of the trapezoidal bottom, the contact area with an automobile cross beam is increased, and the firmness of connection is ensured. In addition, according to the design, the attractiveness and functionality are balanced, the performance of the vehicle is improved, and wide applicability and market application potential are achieved.

    本发明涉及轿车白车身衣帽架技术领域,尤其涉及一种能够提升车身扭转刚度的支撑杆结构,包括V型主体以及在该V型主体两侧对称设置的两个斜撑,所述斜撑方向向下,且所述V型主体与两个所述斜撑一体成型。支撑杆结构通过拓扑优化技术实现了材料的高效利用,提升了整车扭转刚度超过11%,同时简化了制造工艺。该结构采用V型主体与斜撑的创新布局,形成了多个三角形和倒置"W"型结构,增强了稳定性和承载能力。斜撑与V型主体的共线设置和梯形底部设计增加了与汽车横梁的接触面积,确保了连接的牢固性。此外,该设计在美观性与功能性之间取得了平衡,不仅提升了车辆的性能,还具有广泛的适用性和市场应用潜力。
