Rotating shaft mechanism for notebook computer

Abstract

The invention discloses a rotating shaft mechanism for a notebook computer. The rotating shaft mechanism comprises a rotating bracket, a stop block, a shaft core rod, a plurality of loose fin rings and a plurality of tight fin rings; the rotating bracket further comprises a supporting part, a first shaft sleeve and a second shaft sleeve; the first shaft sleeve is located at one end of the lower end face of the rotating bracket; the second shaft sleeve is located at the middle part of the lower end face of the rotating bracket; a turtledove-shaped groove is formed in a region, located between the other end of the lower end face and the second shaft sleeve, on the lower end face of the rotating bracket; one side of the shaft core rod is a polish rod part, and the other side of the shaft corerod is a non-polish rod part; the polish rod part of the shaft core rod is embedded into the first shaft sleeve and the second shaft sleeve of the supporting part; the loose fin rings and the tight fin rings are provided with outwards protruding parts; the outwards protruding parts are embedded into the turtledove-shaped groove of the rotating bracket. The rotating shaft mechanism for the notebook computer is high in stability and uniformity of torsion and friction force; after the rotating shaft mechanism turns over for 20,000 times, the varying range of the torsion and the friction force iscontrolled within 7 percent, and the lubricating property is also improved.

Description

technical field [0001] The invention relates to a rotating shaft mechanism for a notebook computer, in particular to a computer positioning rotating shaft used between a liquid crystal screen board and a mainboard of the notebook computer. 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 notebook computer that is small in size, thin in thickness, light in weight and easy to carry around. Most of the existing notebooks are of flip-top type. In order to meet the design considerations of thinness, smallness and light weight, they are generally designed to be composed of two parts: the base composed of the host body and ...

Problems solved by technology

[0003] In the prior art, the rotating shaft of a notebook computer is generally provided with an annular oil guide groove directly on the pivot of the rotating shaft, and the rotating shaft is made of zinc alloy. This design has the following disadvantages: the rotating shaft of a notebook computer with this structure has slow heat dissipation, There will be local heating, and the lubricating oil in the oil tank will be easily melted. This requires a higher melting point of the lubricating oil in the oil tank. There is an annular oil guide groove on the pivot, which is not conducive to the storage of lubricating oil. When the top cover of the laptop is closed, it may cause oil leakage. At the same time, there is an annular oil guide groove on the pivot, and it is not easy to form a uniform oil film.
