Abstract: A mobile terminal includes a circuit board, a heat emitting element disposed on the circuit board, a shielding can, and a middle frame, where the shielding can is connected to the circuit board, and forms a shielding space together with the circuit board; the heat emitting element is accommodated in the shielding space; the circuit board is disposed on one side of the middle frame; the middle frame is provided with an accommodating space; and the shielding can includes a top and a bottom that are disposed opposite to each other, where the bottom is configured to be connected to the circuit board, and the top is located above the heat emitting element and extends to the accommodating space. The present disclosure further provides a heat dissipation and shielding structure. The present disclosure helps make a mobile terminal and a heat dissipation and shielding structure lighter and thinner.

Abstract: A touchpad assembly includes a baseplate, a support, and a balance bar. The baseplate includes a first plate body and a second plate body. The first plate body is higher than the second plate body in a thickness direction of the touchpad assembly, and the first plate body is configured to accommodate a battery of the electronic device. The support is disposed on a side of the baseplate, the balance bar is supported between the support and the baseplate, and is capable of rotating around a set fulcrum of the baseplate. The balance bar includes a main body portion and supporting portions. At least part of each of the supporting portions is located on the first plate body. An end of each of the supporting portions that extends away from the main body portion does not extend past a bottom surface of the first plate body in the thickness direction.
