The invention provides a battery pack protection structure and an automobile. The battery pack protection structure comprises an upper shell, a lower shell, a mounting plate and a frame, the upper shell and the lower shell are matched to form an accommodating cavity for accommodating a battery pack; the frame is arranged on the periphery of the accommodating cavity; the mounting plates are arranged on the two sides of the frame in the collision direction, and at least two mounting plates arranged on the same side of the frame at intervals are matched to form a first collision energy absorption structure. Through integration of the upper shell and the vehicle body and CTC design, the same set of vehicle body can be shared conveniently; the outer envelope of the whole pack is not changed, and the battery packs of different manufacturers and configurations can be conveniently compatible only through reasonable arrangement, rigidity matching design and internal optimization; z-direction space is reserved through CTC design, Y-direction space is reserved through CTP design, only one cross beam is reserved in the interior, the size of the battery cell is increased to the maximum extent, and the energy density of the battery pack is improved.
本发明提供了一种电池包防护结构及汽车,包括包括上壳体、下壳体、挂载板和边框;所述上壳体和所述下壳体配合,形成用于容置电池包的容置腔体;所述边框设置在所述容置腔体的外围;所述挂载板沿碰撞方向设置在所述边框的两侧,间隔设置在所述边框同一侧的至少两个所述挂载板,配合形成第一碰撞吸能结构。通过上壳体和车体集成、CTC设计,方便共用同一套车体;整包外包络不变,仅通过合理的布置、刚度匹配设计,对内部优化,方便兼容不同厂商、配置的电池包;通过CTC设计让出Z向空间、CTP设计让出Y向空间,内部仅保留中间一根横梁,最大限度增加电芯体积,提高电池包能量密度。
