Shell mounting structure and robot

The utility model relates to a shell mounting structure and a robot. The shell mounting structure comprises an upper shell; the buckle connecting piece is preassembled and fixed on the inner side wall of the upper shell, a clamping groove is formed in the buckle connecting piece, and the notch of the clamping groove is arranged downwards; and the side shell is arranged below the upper shell, and the upper edge of the side shell is inserted into the clamping groove to be fixed. As the side shell is arranged below the upper shell, when the side shell and the upper shell are assembled, only the upper edge of the side shell needs to be aligned with the notch of the clamping groove, then the upper shell is pressed downwards, the upper edge of the side shell can be automatically clamped into the clamping groove, and therefore the upper shell and the side shell are assembled and connected. According to the plug-in mounting mode, the structure is simple, operation is convenient and labor-saving, the buckle connecting
