Curved glass and production method thereof, shell and electronic equipment

Abstract

The present invention provides a curved glass and a production method thereof, a shell and electronic equipment. The production method of the curved glass comprises: providing a first glass plate anda second glass plate, wherein the second glass plate has a hollow structure; fusing the second glass plate to the surface of the first glass plate to form a fusing glass receiving space; carrying outfirst removing on the partial surfaces, away from the receiving space, of the first glass plate and the second glass plate to form a first curved surface; and carrying out second removing on the partial surface, close to the receiving space, of the second glass plate to form a second curved surface, wherein the bending angle of the obtained curved glass is not less than 70 DEG. According to the present invention, with the production method, the curved glass can be directly produced by combining the fusion method, the CNC and other processing methods, and the molding method can be independent of the mold, such that the limitation of the current hot bending method on the glass shape is overcome so as to process the curve glass with the bending angle of not less than 70 DEG, wherein the outercurved surface and the inner curved surface are sequentially processed so as to reduce the stress concentration.

Description

technical field [0001] The present application relates to the technical field of glass forming and processing, and in particular, the present application relates to curved glass, a manufacturing method thereof, a casing and electronic equipment. Background technique [0002] At present, the bending angle of glass achieved by hot bending method can only be less than 90°, and the larger the bending angle is, the more difficult it is for the hot pressing mold to close the mold. Therefore, the current large-angle bending cannot be achieved through thermal Formed by bending method. Contents of the invention [0003] An object of the embodiments of the present application is to provide a method for manufacturing curved glass, the curved glass formed by the method, a casing using the curved glass, and an electronic device using the casing. [0004] In the first aspect of the embodiments of the present application, a method for manufacturing curved glass is proposed. [0005] Ac...
