A top cover front cross beam assembly and a vehicle are disclosed. The assembly comprises a front cross beam body, the front cross beam body is provided with a groove extending in the length direction of the front cross beam body, and an opening of the groove extends outwards to form first turnups; a plurality of reinforcing pieces are arranged in the length direction of the front cross beam body at intervals, the edges of the reinforcing pieces are provided with second turnups in lap joint with the first turnups correspondingly, and the middles of the reinforcing pieces are sunken downwards to form bosses fixedly connected with the bottoms of the grooves. The top cover front cross beam assembly is simple in structure, the rigidity and the structural mode of the top cover front cross beam assembly can be improved, and the NVH performance is improved.
本发明公开了一种顶盖前横梁总成及车辆,包括前横梁本体,所述前横梁本体具有沿前横梁本体长度方向延伸的凹槽,所述凹槽的开口处向外延伸形成第一翻边;沿前横梁本体长度方向间隔设置多个加强件,所述加强件边沿设有与第一翻边对应搭接的第二翻边,加强件中部向下凹陷形成与凹槽槽底固定连接的凸台。其结构简单,能够提升顶盖前横梁总成的刚度和结构模态,提升NVH性能。
