Abstract

The invention provides a battery cover, a preparation method of the battery cover, and a mobile terminal. The preparation method of the battery cover comprises the following steps: providing a ceramicsubstrate, wherein the ceramic substrate comprises an inner surface and an outer surface which are oppositely arranged; forming a reinforcing layer covering the ceramic substrate on the inner surfaceof the ceramic substrate; processing the outer surface, so that the thickness of the ceramic substrate is reduced to a first preset thickness; and processing the reinforcing layer, so that the thickness of the reinforcing layer is reduced to a second preset thickness. The thickness of the ceramic substrate in the battery cover can be reduced to an expected value under the condition that the ceramic substrate is not broken, and the prepared battery cover has sufficient structural strength on the premise that the weight of the prepared battery cover is close to a glass front cover.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a battery cover, a preparation method thereof, and a mobile terminal. Background technique [0002] In related technologies, mobile terminals such as smartphones and tablet computers use ceramic back covers and glass front covers. The ceramic back cover has a relatively large weight due to its thickness, which makes the weight difference between the ceramic back cover and the glass front cover large, which is serious. It affects the overall weight of the mobile terminal. In order to balance the weight of the ceramic back cover and the glass front cover, the weight difference between the two should be reduced. In the related art, the thickness of the ceramic back cover is thinned so as to reduce the weight of the ceramic back cover. However, during the process of reducing the thickness of the ceramic back cover, the ceramic back cover is likely to be broken, an...
