The invention discloses a front top cross beam modal reinforcing structure, a front top structure and a vehicle, the front top cross beam modal reinforcing structure comprises a front top cross beam reinforcing plate and a front top cross beam inner plate, the middle of the front top cross beam reinforcing plate is provided with a convex surface, the middle of the front top cross beam inner plate is provided with a groove surface, and the convex surface is provided with a concave surface; the front top cross beam reinforcing plate comprises a front top cross beam inner plate and a front top cross beam reinforcing plate, the front top cross beam inner plate is provided with a groove face, the two sides of the groove face form sunken table faces, the protruding face of the front top cross beam reinforcing plate and the groove face of the front top cross beam inner plate are connected in a welded mode, and the front top cross beam reinforcing plate and the front top cross beam inner plate form two cavities which are the first cavity and the second cavity. According to the front top cross beam structure, the strength and rigidity of the whole front top cross beam structure are improved, the first cavity and the second cavity are each of a through structure, and therefore additional structures such as reinforcing rib plates and reinforcing beams do not need to be arranged on the front top cross beam reinforcing plate and the front top cross beam inner plate, the whole structure of the front top cross beam is simplified, and the purpose of light weight is achieved.

    本发明公开了一种前顶横梁模态增强结构、前顶结构及车辆,所述前顶横梁模态增强结构,包括前顶横梁加强板和前顶横梁内板,所述前顶横梁加强板的中间设置凸起面,所述前顶横梁内板的中间设置有凹槽面,所述凹槽面的两侧形成沉台面,所述前顶横梁加强板的凸起面和所述前顶横梁内板的凹槽面通过焊接的方式进行连接,前顶横梁加强板和前顶横梁内板在一起形成两个腔体,为第一腔体和第二腔体;本发明提高了整体前顶横梁结构的强度和刚度,第一腔体和第二腔体均为贯通式结构,进而无需在前顶横梁加强板和前顶横梁内板上设置额外的加强肋板、加强梁等结构,简化了前顶横梁的整体结构,并且实现了轻量化的目的。
