Folding apparatus and electronic device

An electronic device, comprising:

• a flexible display and a folding apparatus, and the flexible display is fixed to the folding apparatus;
• wherein the folding apparatus comprises a first housing, a first support plate, and a middle housing that are configured to support a flexible display and that are sequentially arranged in an extension direction of the flexible display, and the folding apparatus further comprises a first mounting bracket, a first transmission arm, and a first rotating arm;
• the first mounting bracket is fixed to the first housing, the first transmission arm is rotatably connected to the middle housing, a rotation center is a first axis, the first transmission arm is slidably connected to the first mounting bracket, and the first transmission arm is slidably connected to the first support plate;
• the first rotating arm is rotatably connected to the middle housing, a rotation center is a second axis, the first rotating arm is rotatably connected to the first mounting bracket, and the second axis and the first axis are not collinear;
• and
• the first support plate is rotatably connected to the first mounting bracket, and the first support plate can be driven by the first transmission arm, through sliding of the first transmission arm relative to the first mounting bracket, to rotate relative to the middle housing, so that the first housing and the first support plate switch between a flattened state and a folded state.
