Abstract: The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state.

Abstract: A rotation mechanism, includes a middle housing (1), a first support (2) and a second support (3), a first end of the first support is rotatably connected to the middle housing, and a second end of the first support is fixedly connected to a first housing; a first end of the second support is rotatably connected to the middle housing, and a second end of the second support is fixedly connected to a second housing.

Abstract: A rotating mechanism includes a main shaft assembly, a first fixed bracket, a second fixed bracket, a first transmission arm, a first rotating arm, a second transmission arm, and a second rotating arm. One end of the first transmission arm is slidably connected to the second fixed bracket, and the other end of the first transmission arm is a rotating end and is rotatably connected to the main shaft assembly. Two ends of the first rotating arm are rotatably connected to the first transmission arm and the first fixed bracket respectively. One end of the second transmission arm is slidably connected to the first fixed bracket, and the other end of the second transmission arm is rotatably connected to the main shaft assembly. Two ends of the second rotating arm are rotatably connected to the second transmission arm and the second fixed bracket respectively.
