Abstract

The invention relates to a preparation method of a shell assembly, the shell assembly and a mobile terminal. The preparation method of the shell assembly comprises the following steps: obtaining a shell blank; carrying out laser processing on the outer surface of the shell blank in an oxygen-free environment or an inert gas atmosphere so as to process convex-concave lines on the outer surface of the shell blank, wherein the depth of the convex-concave lines ranges from 0.02 mm to 0.20 mm, and the grain spacing of the convex-concave grains ranges from 0.02 mm to 0.30 mm. According to the manufacturing method of the shell assembly, the shell assembly and the mobile terminal, the anti-skid performance of the shell assembly is improved through the convex-concave lines machined on the outer surface of the shell blank through laser, and therefore the mobile terminal is prevented from falling off and being damaged easily.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a method for preparing a shell assembly, a shell assembly, and a mobile terminal. Background technique [0002] Ceramics have properties such as high strength, high gloss, high fracture toughness, excellent heat insulation performance, and high temperature resistance. As structural parts of mobile terminals such as mobile phones and tablet computers, ceramics are widely used in shell component structures such as back covers and middle frames. , has been welcomed by consumers. [0003] In order to keep the camera from protruding, a built-in camera is currently used, and a sapphire or camera lens is inlaid on the surface of the back cover. In order to prevent the camera lens or sapphire from being scratched and affect the image effect, an anti-friction protrusion protruding from the surface of the back cover is usually provided on the surface of the back cover c...
