Abstract

Embodiments in the invention provide a ceramic shell structure member, comprising a ceramic shell and a frame equipped with a recessed part, wherein the ceramic shell comprises a ceramic flat plate and a ceramic protruding member outwardly protruding from the side surface of the ceramic flat plate, the ceramic protruding member is arranged in the recessed part of the frame so as to allow the ceramic shell to be compactly jointed with the frame, the upper surface of the joint of the frame and the ceramic protruding member is aligned with the upper surface of the ceramic flat plate along the thickness direction of the ceramic flat plate, and the frame covers the side surfaces of the ceramic shell or the side and bottom surfaces of the ceramic shell and is made of an alloy, a metal-based composite or plastic. According to the invention, the frame can protect the edges of the ceramic shell from direct collision with other objects, the ceramic protruding member can increase the bonding force between the ceramic shell and the frame, so the integral anti-breaking capability of the ceramic shell structure member is improved and the application scope of the ceramic shell structure member is broadened. The embodiments in the invention further provide a preparation method for the ceramic shell structure member and a mobile phone. The mobile phone comprises the ceramic shell structure member.

Description

technical field [0001] The invention relates to a ceramic product structure, in particular to a ceramic housing structure, a preparation method thereof and a mobile phone. Background technique [0002] Ceramics are a common class of structural materials. With the rapid development of digital products such as smart phones, major companies are actively developing unique structural materials for digital products to seize commercial selling points, such as developing ceramic materials as mobile phone casings. Understandably, the shell material needs to have a certain anti-drop performance, and at the same time, it should be low-cost and easy to prepare. However, ceramic materials are easily damaged when they collide with other objects because of their brittleness. This shortcoming restricts Application of ceramic materials as housings. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a ceramic shell structural part to solve ...
