Synchronous rotation mechanism and foldable electronic device

A foldable electronic device, comprising:

• a first housing;
• a second housing;
• and
• a foldable screen, arranged on the first housing and the second housing;
• wherein the first housing is connected to the second housing by a synchronous rotation mechanism, and the synchronous rotation mechanism comprises a sliding member, a first torque swing arm, and a second torque swing arm;
• wherein a first helical slot and a second helical slot are respectively provided on two sides of the sliding member;
• wherein the first torque swing arm and the second torque swing arm are respectively located at the two sides of the sliding member, and the first torque swing arm and the second torque swing arm are rotatably connected to the sliding member separately;
• wherein the first torque swing arm is provided with a first slider, and the first slider is accommodated in the first helical slot, so that the first slider slides along the first helical slot when the first torque swing arm rotates, to synchronously drive the sliding member to slide in a direction perpendicular to rotation of the first torque swing arm;
• and
• wherein the second torque swing arm is provided with a second slider, and the second slider is accommodated in the second helical slot, so that the second slider slides along the second helical slot when the second torque swing arm rotates, to synchronously drive the sliding member to slide in a direction perpendicular to rotation of the second torque swing arm.
