The invention relates to a front windshield lower cross beam assembly of a non-bearing type vehicle body, and belongs to the technical field of non-bearing type vehicle bodies, and the front windshield lower cross beam assembly comprises a front windshield lower cross beam which comprises a front windshield lower cross beam water flowing groove body with an upward opening and an n-shaped cross section, a front windshield attaching cross beam which is positioned in the front windshield lower cross beam gutter channel body, is provided with a downward opening and has an n-shaped cross section; the front flanging of the front windshield attaching cross beam is fixedly connected with the groove bottom of the front windshield lower cross beam water flowing groove body, the rear flanging of the front windshield attaching cross beam is fixedly connected with the rear flanging of the front windshield lower cross beam water flowing groove body, and the front windshield attaching cross beam and the front windshield lower cross beam water flowing groove body form a closed hollow structure. According to the front windshield lower cross beam, the transverse structural rigidity of the upper portion of the vehicle body front wall is improved, the torsional rigidity of the vehicle body is improved, and the NVH performance of the upper portion of the vehicle body front wall is enhanced. The structure is simple, the improvement performance is obvious, and the pedestrian protection performance of the large SUV model is not reduced.
本申请涉及一种非承载式车身的前风窗下横梁总成,属于非承载式车身技术领域,包括:前风窗下横梁,其包括开口朝上且横截面呈“几”字形结构的前风窗下横梁流水槽体,以及位于前风窗下横梁流水槽体内且开口朝下横截面呈“几”字形结构的前风窗贴合横梁;前风窗贴合横梁的前翻边与前风窗下横梁流水槽体的槽底固定连接,前风窗贴合横梁的后翻边与前风窗下横梁流水槽体的后翻边固定连接,前风窗贴合横梁与前风窗下横梁流水槽体形成闭合的空心结构。本申请的前风窗下横梁以增加车身前围上部的横向结构刚度,进而提升车身扭转刚度和增强车身前围上部NVH性能。该结构简单,提升性能显著,也不降低大型SUV车型的行人保护性能。
