Foldable display terminal and middle frame

A foldable display terminal, comprising:

• a first middle frame and a second middle frame;
• and
• a hinge structure, wherein the first middle frame and the second middle frame are disposed on two sides of the hinge structure, and the first middle frame and the second middle frame rotate toward each other through the hinge structure, so that the foldable display terminal is capable of performing switching between a flattened state and a folded state, wherein when the foldable display terminal is in the flattened state, the first middle frame and the second middle frame are in a flattened disposition;
• an edge of the first middle frame comprises a first top surface, an edge of the second middle frame comprises a second top surface, the first top surface comprises a first protrusion part, and the second top surface comprises a second protrusion part;
• and
• when the foldable display terminal is in the folded state, the first top surface faces the second top surface, a gap exists between the first top surface and the second top surface, the first protrusion part faces the second protrusion part, and a gap exists between the first protrusion part and the second protrusion part.
