Abstract

The embodiment of the invention discloses a method for preparing a casing composite structure and a casing composite structure. The preparation method of the combined shell structure includes: preparing a shell, preparing a plastic bracket, fixing the plastic bracket on the shell, obtaining a first product of the combined shell structure, and presetting the first product of the combined shell structure The structure is processed to obtain the combined structure of the shell. Since the shell and the plastic bracket contain a reserved amount to be processed by the preset structure, the preset structure processing of the shell composite structure is carried out after the plastic bracket is fixed on the shell, so the shell and the plastic bracket in the prepared shell composite structure The accuracy of assembly dimensions is high, which meets the accuracy requirements of the shell assembly structure for assembly dimensions, improves the assembly yield of the shell assembly structure and the complete machine, and reduces the production cost of the shell assembly structure and the entire machine.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for preparing a shell assembly structure and a shell assembly structure. Background technique [0002] Because of their strong plasticity and low price, ceramics and glass have been widely used in the preparation of terminal casings, such as mobile phone casings and wearable device casings. The terminal generally includes a terminal housing and a plastic bracket, and the plastic bracket is fixed on the terminal housing to form a combined shell structure. [0003] At present, when the terminal includes a ceramic shell or a glass shell, the ceramic shell or the glass shell is molded separately, and the plastic bracket of the terminal is also molded separately. The way of glue is fixed to the ceramic shell or glass shell, and the assembly of the terminal shell and the plastic bracket is completed. Formed ceramic housings or glass housings are constructed as figure 1 As shown...
