Laptop

Abstract

The invention discloses a laptop. The laptop comprises a base, a display screen, connecting columns and rotating shaft mechanisms used for connecting the base with the connecting columns. The connecting columns are fixedly connected with the display screen through fixed plates located at the ends of the connecting columns; each rotating mechanism further comprises a rotating support, a check block, a shaft core rod, a plurality of loosening fin rings and a plurality of fastening fin rings; polished rod parts are arranged on one sides of the shaft core rods, and unpolished rod parts are arranged on the other sides of the shaft core rods; the polished rod parts of the shaft core rods are embedded into first shaft sleeves and second shaft sleeves of supporting parts, and the unpolished rod parts of the shaft core rods are embedded into third through holes of the connecting columns; the fastening fin rings are in matched connection with the polished rod parts; and the loosening fin rings and the fastening fin rings are arranged alternately. The laptop is good in torque and friction stability and uniformity, and after 20000 times of turnover, the floating range of torque and friction is controlled with 7%, so that torque damping is reduced, the surface of the base is contacted, fixing strength and stability are higher.

Description

technical field [0001] The invention relates to a notebook computer, in particular to a notebook computer with a computer positioning rotating shaft. 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 the keyboard, and the upper cover composed of the display screen and the cover. . When t...

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.
