Abstract: A foldable apparatus and an electronic device, wherein foldable apparatus includes a mounting bracket and a rotating bracket assembly. The rotating bracket assembly includes a first rotating bracket and a second rotating bracket arranged on two sides of the mounting bracket along a width direction of the mounting bracket. The first rotating bracket is rotatably connected to the mounting bracket by using a first rotating shaft. The second rotating bracket is rotatably connected to the mounting bracket by using a second rotating shaft. When the first rotating bracket and the second rotating bracket rotate toward each other, the first rotating shaft and the second rotating shaft move in a direction away from the mounting bracket along the width direction of the mounting bracket.

Abstract: A rotating shaft mechanism (10) is provided, including a main bracket (1) and at least one rotating assembly (2). Each rotating assembly can rotate relative to the main bracket. The rotating assembly includes a rotating member (21), a middle frame (22), and a sliding member (23). The rotating member can be rotatably connected to the main bracket about the first rotation center, and the other end of the rotating member can be rotatably connected to the middle frame about the third rotation center. One end of the sliding member is hinged to the main bracket, and the sliding member can rotate relative to the main bracket about the second rotation center. The other end of the sliding member slidably coordinates with the middle frame, so that the middle frame is away from or close to the second rotation center along an extension direction of the sliding member.

Abstract: A rotating shaft apparatus is provided, where the rotating shaft apparatus includes an adapter member, a spindle, and a crank-slider mechanism. The adapter member is fixedly connected to a load. The spindle is fixedly connected to the adapter member. The crank-slider mechanism acts on the spindle to provide a torque. The torque partially or completely counteracts a gravitational torque of the load. A compression spring is disposed in the crank-slider mechanism. A spring force of the compression spring acts on the spindle, so that the spring force changes with rotation of the spindle.
