The invention belongs to the technical field of power battery installation, and discloses a power battery frame for a commercial vehicle and the commercial vehicle. The power battery frame for the commercial vehicle comprises vertical beams, a bottom-layer frame, a mounting layer and a top-layer frame, the bottom-layer frame is composed of tubular beams with first wall thickness, and the vertical beams are supported on the bottom-layer frame; the mounting layer is supported on the bottom layer frame or the first longitudinal beams and is formed by tubular beams with second wall thickness; the top-layer frame is supported at the top ends of the vertical beams, and the top-layer frame is formed by tubular beams with third wall thickness; the first wall thickness > the second wall thickness > the third wall thickness. According to the invention, the tubular beams with different wall thicknesses are optimally designed, so that the lightweight design is realized on the premise of meeting the structural strength of the power battery, and the overall weight can be reduced by more than 15%.

    本发明属于动力电池安装技术领域,公开了一种商用车用动力电池框架和商用车。商用车用动力电池框架包括竖梁、底层框架、安装层和顶层框架,底层框架采用具有第一壁厚的管梁构成,竖梁支撑于底层框架上;安装层支撑于底层框架或第一纵梁上,安装层采用具有第二壁厚的管梁构成;顶层框架支撑于竖梁的顶端,顶层框架采用具有第三壁厚的管梁构成;第一壁厚>第二壁厚>第三壁厚。本发明通过优化设计不同壁厚的管梁,使其在满足安装动力电池的结构强度的前提下,实现了轻量化设计,能够实现整体降重超过15%。
