The invention discloses an under-vehicle protection plate assembly and a railway vehicle. The under-vehicle protection plate assembly comprises a plurality of protection plates arranged in a protection area below a vehicle body chassis, and the protection area comprises a first protection area and a second protection area which are located on the outer side of a sleeper beam and distributed left and right, and a third protection area and a fourth protection area which are located on the inner side of the sleeper beam and distributed left and right. At least two protection plates are arranged in each of the first protection area and the second protection area. At least three protection plates are arranged in each of the third protection area and the fourth protection area. Connecting holesare formed in the positions, close to the edge, of the periphery of each protection plate, and reinforcing rib protrusions are arranged on the edge of each protection plate. According to the under-vehicle protection plate assembly, the structure of the protection plates is simplified, the types of the protection plates are reduced, modular design can be conducted, the applicability of the protection plates is improved, the self weight of the protection plates is reduced on the premise that the rigidity requirement is met, and the production efficiency can be remarkably improved by improving and unifying the installation mode.

    本发明公开了一种车下防护板组件及轨道车辆,所述车下防护板组件包括设于车体底架下方防护区域内的多块防护板,所述防护区域包括位于枕梁外侧且左右分布的第一防护区域和第二防护区域,以及位于枕梁内侧且左右分布的第三防护区域和第四防护区域;所述第一防护区域和第二防护区域内分别设有至少两块防护板,所述第三防护区域和第四防护区域内分别设有至少三块防护板;各所述防护板的四周在接近边缘的位置设有连接孔,并在边缘设置有加强筋凸起。该车下防护板组件简化了防护板结构,减少了防护板种类,可进行模块化设计,从而提高防护板的适用性,在满足刚度要求的前提下,减轻了防护板自重,通过改进和统一安装方式,可显著提高生产效率。
