The invention provides a mounting structure for a battery shell of an electric vehicle. The mounting structure comprises a battery pack shell and a battery pack reinforcing and fixing frame, the battery pack shell comprises an upper shell and a lower shell, and the upper shell and the lower shell are detachably connected and enclose to form a battery cavity for placing a battery; an upper sealing edge is formed around the periphery of the upper shell, and a lower sealing edge is formed around the periphery of the lower shell; the outer side part of the lower surface of the upper sealing edge is a first sealing surface, and the inner side part is a second sealing surface; the first sealing face and the lower sealing edge are tightly connected in an attached mode, a gap is formed between the second sealing face and the lower sealing edge, and the gap is filled with foaming cotton. The battery pack reinforcing and fixing frame is fixed to a vehicle body, a battery pack shell containing space is formed in the middle of the battery pack reinforcing and fixing frame, and the battery pack shell is detachably connected to the battery pack reinforcing and fixing frame. According to the battery shell mounting structure, the light weight requirement of the battery pack can be met, the energy density of the battery pack is improved, and the higher-standard whole vehicle requirement can be met.
本发明提供一种电动汽车电池壳体安装结构,包括电池包壳体和电池包加强固定框。电池包壳体包括上壳体和下壳体,上壳体和下壳体之间可拆卸地连接并包围形成用于放置电池的电池腔;上壳体环绕周边形成有上密封边,下壳体环绕周边形成有下密封边;上密封边的下表面靠外侧部分为第一密封面,靠内侧部分为第二密封面;第一密封面与下密封边之间紧密贴合连接,第二密封面与下密封边之间具有间隙,该间隙内填充有发泡棉。电池包加强固定框固定在车身上,中部形成有电池包壳体容置空间,电池包壳体可拆卸地连接于电池包加强固定框上。本电池壳体安装结构既能保证电池包本身的轻量化要求,提高电池包能量密度,又能满足更高标准的整车要求。
