The embodiment of the invention provides a shell, a battery pack and a device. The shell comprises an upper box body and a lower box body, wherein the lower box body is used for being connected with the upper box body, the lower box body comprises a frame and a cross beam, the cross beam is located in the frame, the cross beam and the frame are used for defining two or more accommodating spaces for accommodating battery modules, and the cross beam protrudes out of the frame in the direction from the lower box body to the upper box body. According to the embodiment of the invention, the cross beam of the shell protrudes out of the frame, i.e., the cross beam is high, so that the structural rigidity of the shell in the height direction can be improved due to the high cross beam, the bendingdeformation of the cross beam is inhibited, and the shell is prevented from deforming.
本发明实施例提供一种壳体、电池组及装置,壳体包括:上箱体;下箱体,用于与上箱体连接,下箱体包括边框和横梁,横梁位于边框内部,横梁和边框用于围合形成两个以上容纳电池模块的容纳空间,在下箱体至上箱体的方向上,横梁凸出于边框。本发明实施例中壳体的横梁凸出于边框设置,即横梁较高,横梁较高能够增加壳体在高度方向上的结构刚度,抑制横梁发生挠曲变形,防止壳体发生变形。
