The invention provides a battery pack box body, a battery pack and a vehicle, the battery pack box body comprises a box body, a plurality of mounting beams and a plurality of lining structures, the box body comprises a bottom plate and side plates connected to the circumferential direction of the bottom plate, the bottom plate and the side plates define a containing space, the bottom plate is provided with a plurality of protruding parts, and the protruding parts protrude towards the side of the containing space; the mounting beams are located in the containing space, the two ends of each mounting beam are connected with the side plates respectively, and a plurality of mounting holes are formed in the mounting beams and are opposite to the protruding parts; each lining structure comprises a lining body, the lining bodies are connected with the mounting beams and the protruding parts, the lining bodies are partially located in the mounting holes, each lining body is provided with a first end face, and the first end faces are glued to the surfaces of the protruding parts so that the mounting beams can be spaced from the bottom plate by a certain distance. The technical problems that the mounting beam in a suspended area is poor in structural strength and prone to flapping abnormal sound due to the fact that the mounting beam in the battery box and the bottom of the battery box are suspended are solved.

    本发明提供一种电池包箱体、电池包和车辆,电池包箱体包括箱本体、多个安装梁和多个衬套结构,箱本体包括底板和连接于底板周向的侧板,底板与侧板围成容纳空间,底板设有多个凸起部,凸起部向容纳空间侧隆起;多个安装梁位于容纳空间内,安装梁的两端分别与侧板连接,安装梁上开设有多个安装孔,安装孔与凸起部相对;每个衬套结构包括衬套本体,衬套本体连接安装梁和凸起部,衬套本体部分位于安装孔内,衬套本体具有第一端面,第一端面与凸起部的表面胶粘,以使得安装梁与底板间隔一定距离。改善因电池箱体内的安装梁与电池箱体底部悬空,导致悬空区域的安装梁结构强度差和易出现拍打异响的技术问题。
