The invention designs a manufacturing method of a top cover cross beam, the top cover cross beam, a body in white and a vehicle, the manufacturing method comprises the steps that a corresponding supplementary plate blank is stacked on each substrate weak area of a substrate blank, and the substrate blank and the supplementary plate blank are both of a plate body structure; the base plate blank is connected with the stacked supplementary plate blank to obtain an integrated target blank; and forming the target blank according to a preset shape to obtain the top cover cross beam. According to the top cover cross beam, the base plate blank can be locally reinforced, the local rigidity of the base plate blank is improved, the vibration noise of the top cover cross beam is reduced, the number of parts is reduced, the assembling difficulty is lowered, the occupied space is small, and related parts can be conveniently arranged on the top of a vehicle.
本申请设计一种顶盖横梁的制造方法、顶盖横梁、白车身及车辆,制造方法包括:在基板胚料的每个基板薄弱区域上叠设对应的补板胚料,所述基板胚料与所述补板胚料均为板体结构;将所述基板胚料与叠设的所述补板胚料相连得到一体化的目标胚料;对所述目标胚料按预设造型成型得到顶盖横梁。可以对基板胚料进行局部补强,提高基板胚料的局部刚度,降低顶盖横梁的振动噪音,且减少了零件数量,降低了装配的难度,且在空间上占用较少,便于相关零件在车辆顶部的布置。
