Portable computer rotary shaft cavity and manufacturing method thereof

Abstract

The invention discloses a portable computer rotary shaft cavity and a manufacturing method thereof. The rotary shaft cavity comprises a cylindrical cavity body and a baffle arranged in the cylindricalcavity body, wherein a containing space is formed in the cylindrical cavity body, the baffle and the inner wall of the cylindrical cavity body are in spot-welding connection, the baffle is perpendicular to the inner wall of the cylindrical cavity body, and the baffle is welded to the inner wall of the cylindrical cavity body by the adoption of laser spot welding. The rotary shaft cavity is simplein structure, attractive in appearance, convenient to machine and form and high in matching degree with a rotary shaft of a portable computer; after installation of the rotary shaft cavity, the rotary shaft cannot get loose, fitness is high, rotation is stable, and the service life of a product is long; and the baffle and the cylindrical cavity body are connected through laser spot welding without residues, the joint is perfect, and the cavity is suitable for a high-end portable computer.

Description

technical field [0001] The invention belongs to the technical field of a laptop computer shaft, and in particular relates to a laptop computer shaft cavity and a manufacturing method thereof. Background technique [0002] With the development of science and technology, various electronic products continue to appear, which bring great changes to people's lives, especially the use of computers has changed people's lifestyles and accelerated their pace of life. In the past two decades, with the development of material science and the emergence of smaller integrated chips, computers have evolved into a portable computer that is small in size, thin in thickness, light in weight and easy to carry around. Most of the existing portables are flip-top type. In order to meet the design considerations of thinness, small size and light weight, they are generally designed to be composed of two parts: the base composed of the host body and the keyboard, and the upper cover composed of the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the rotating shaft part used to connect the laptop display and keyboard body is a zinc alloy integral die-casting part. Because it is the connecting key of the laptop display and keyboard and is exposed, the appearance requirements are high and the colors are diverse. However, die-casting molding is very difficult. It is difficult to meet the appearance requirements: there are parting lines on the surface, and bubbles will be generated during electroplating treatment; the product cavity is deep, die-casting, and the core draft angle is large, it is difficult to meet the vertical aesthetic requirements, and the surface treatment is currently only Can be electroplated, but cannot meet diverse needs

[0004] In addition, the Chinese patent "Laptop wiring structure in the shaft compartment", application number 201310057297.0, application publication number CN 103149988 A, only discloses "including the notebook shaft compartment, and a pair of inwardly opened clamping wires are symmetrically arranged inside the shaft compartment." The door, the wire clamping door or the wire clamping door and the inner wall of the shaft compartment are used to set the wiring position", which focuses on the wiring structure of the shaft compartment, and does not solve the above problems
