Electronic equipment, rotating shaft, layered composite material and manufacturing method of layered composite material

Abstract

The embodiment of the invention provides electronic equipment, a rotating shaft, a layered composite material and a manufacturing method thereof, the layered composite material comprises at least two material layers which are stacked, the at least two material layers comprise a first material layer and a second material layer which are adjacent, the first material layer is made of a first metal material, and the second material layer is made of a second metal material. The yield strength of the first metal material is larger than 200 Mpa, and the elongation of the first metal material is larger than 6%; the second material layer is made of the first composite material, and the first composite material comprises the second metal material and the diamond particles, so that the fracture resistance and the wear resistance of the rotating shaft are ensured, the heat conduction and heat dissipation performance of the rotating shaft is improved, and the experience feeling of a user is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of terminals, and in particular to an electronic device, a rotating shaft, a layered composite material and a manufacturing method thereof. Background technique [0002] Mobile phones, computers and other electronic devices have been inseparable from our lives, can be seen everywhere in our lives, and have greatly improved people's living standards. With the rapid development of communication equipment technology, the functions of electronic products such as notebook computers, folding screen mobile phones, and tablet computers have gradually increased, and energy consumption has also increased. Consumers have also put forward higher and higher requirements for the performance of electronic products. Among them, the heat dissipation problem is a key factor related to the performance of electronic products. Therefore, the heat dissipation problem of electronic products is becoming ...

Problems solved by technology

[0004] However, when the rotating part rotates around the fixed part, friction and heat will be generated when the two contact each other, the anti-drop performance, wear resistance and thermal conductivity of the above-mentioned rotating shaft are relatively poor, and the poor anti-drop performance and wear resistance of the notebook computer lead to The whole machine is prone to wear, looseness or even breakage during the rotation process. The poor thermal conductivity leads to poor overall cooling effect of the notebook computer, which greatly affects the experience effect of the notebook computer.
