Module shell, battery pack and automobile

The utility model relates to the technical field of batteries, and provides a module shell, a battery pack and an automobile, the module shell is formed by assembling a plurality of matched structuralmembers, each structural member comprises a metal structural member and a plastic structural member, and the metal structural member and the plastic structural member are overlapped to form the module shell. According to the module shell provided by the utility model, each structural member comprises the metal structural member and the plastic structural member, and the overall weight reduction of the module shell is realized by utilizing the characteristic of light weight of the plastic structural member. Meanwhile, the characteristic that the metal structural part is good in heat dissipation is utilized, the normal heat dissipation process of the membrane module shell is guaranteed, and therefore the module shell is lighter in overall weight on the basis of having the good heat dissipation function. 本实用新型涉及电池技术
