Abstract: The present disclosure relates to a riveted metal middle frame comprising a middle plate and a border frame riveted to the middle plate. The middle plate is made of aluminum alloy, and the periphery of the middle plate is convexly provided with convex edge. The border frame comprises a plurality of members connected end to end in sequence. The members are made of metal material with hardness not less than aluminum alloy, and the members are riveted to the periphery of the middle plate, and the inner sides of the members are respectively provided with slot for connecting the convex edge. A riveting between the convex edge and the slot may be achieved by press-fitting the border frame. At the same time, an electronic device comprising the above-described riveted metal middle frame is also provided. The beneficial effects of the invention are that the middle plate and the border frame are riveted together by press-fitting deformation, thereby improving production efficiency and reducing manufacturing cost.
