Abstract: Example mobile terminals are disclosed. One example terminal includes a rotating member, a flexible screen, a bending support part, and a temperature equalization plate. The flexible screen includes two unfolded regions and a bent region that is disposed opposite to the rotating member. The bending support part is located between the flexible screen and the rotating member. The temperature equalization plate is configured to balance temperatures in the two unfolded regions and includes two temperature equalization parts opposite to the two unfolded regions in a one-to-one correspondence and a flexible connection part that connects the two temperature equalization parts. The flexible connection part is located on a side of the bending support part and away from the flexible screen.

Abstract: In an electronic device, a circuit board connects different systems or structures such that heat of a system with a relatively large amount of heat can be transferred to a position or a heat dissipation structure with a relatively small amount of heat, thereby mitigating local high temperatures in the electronic device and distributing heat more evenly throughout the electronic device.

Abstract: A camera assembly is provided. The camera assembly includes an auxiliary mount, a rotatable camera module and a flexible heat conducting assembly, the rotatable camera module includes a rotatable mount and a camera function group disposed on the rotatable mount, the rotatable mount is rotatably connected to the auxiliary mount, the flexible heat conducting assembly is fixedly connected to one end of the camera function group, and the flexible heat conducting assembly is further configured to be connected to a non-rotatable camera module component, so that heat generated by the camera function group is transferred to the non-rotatable camera module component. A flexible heat conducting assembly performs a cross-region transfer of heat generated by the rotatable camera module, to help reduce an ambient temperature of the rotatable camera module, so as to improve photography quality of the camera module, and prolong a photography time period of the rotatable camera module.

Abstract: This application provides a foldable screen device. The foldable screen device in this application includes two frames that are jointly articulated with a rotating shaft assembly. The two frames may rotate around rotating shafts of the rotating shaft assembly to be closed or opened. The rotating shaft assembly includes a connection structure and hinges. The connection structure has a channel that passes through two opposite sides of the rotating shaft assembly, and an electrical connection line of the foldable screen device penetrates into the channel. Two ends of the electrical connection line are respectively connected to the two frames, and the hinges and the channel are located at different positions of the rotating shaft assembly in an axial direction. In this way, bending deformation generated by the electrical connection line when the foldable screen device is folded is relatively small, and connection reliability is high.
