Problems solved by technology

Its disadvantages are: the structure of the mobile phone with sliding cover cannot meet the requirement of ultra-thin; and because the mobile phone shell uses metal plates, in order to solve the problem of bonding between the metal plate and the carbon fiber plate on the surface, the surface treatment of the metal plate must be carried out. Complicated, the mobile phone structure cannot be ultra-thin

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0021] Please refer to the accompanying drawings, the ultra-thin battery cover made of curved carbon fiber material is composed of an injection molded frame 1 for the battery cover of a mobile phone, and a curved carbon fiber composite plate 2 set in the injection molded frame 1 and injected in the mold. The curved carbon fiber composite board 2 is provided with a speaker hole 22 and an outline of a camera avoidance hole 21 . The mobile phone battery cover is applied to the mobile phone whose battery cover cannot be plugged and unplugged.

[0022] The manufacturing process of the ultra-thin battery cover made of the curved carbon fiber material includes the following steps:

[0023] (1) Preparation of raw materials: Weave carbon fiber sheets into square carbon fiber silk made by a textile machine; then soak them in epoxy resin solution, heat them to a semi-cured ...

Abstract

The invention relates to an ultrathin battery cover made of a curved-surface carbon fiber material and a manufacturing process of the ultrathin battery cover. The battery cover consists of an injection molding frame of the battery cover and a curved-surface carbon fiber composite plate which is sleeved in the injection molding frame and is subjected to injection molding in a die. The manufacturing process of the battery cover comprises the following steps of: stacking a plurality of semi-solidified carbon fiber epoxy resin between a male die and a female die of a carbon fiber molding die, and enabling the semi-solidified carbon fiber epoxy resin to be completely solidified under the heating condition of 220-230DEG C / 3-5H to form the curved-surface carbon fiber composite plate; engraving outlines of a loudspeaker hole and a camera clearance hole on the formed curved-surface carbon fiber composite plate; forming an assembly of the curved-surface carbon fiber composite plate and the injection molding frame by injection molding; and spraying the assembly of the curved-surface carbon fiber composite plate and the injection molding frame.

Description

technical field [0001] The invention relates to an ultra-thin battery cover made of curved carbon fiber material and a manufacturing process thereof. Background technique [0002] CN 200820214022.8 announced "a sliding mobile phone skateboard and its mobile phone", and its purpose is to provide a sliding mobile phone skateboard with good hand feeling and light weight. The technical scheme is: the slide mobile phone slide plate, the slide mobile phone includes a mobile phone main body and a sliding mechanism, the sliding mechanism includes a slide plate and a sliding assembly, the slide plate is connected to the mobile phone main body and the sliding assembly, and the slide plate includes successively laminated carbon fiber layers, adhesive laminated and sheet metal. The sliding mobile phone skateboard replaces part of the thickness of the metal plate with a carbon fiber layer, which can reduce the weight of the skateboard to a certain extent. Its disadvantages are: the str...
