Description
ROTATING SHAFT MECHANISM FOR LAPTOP
TECHNICAL FIELD [0001] The present disclosure relates to the technical field of notebook computer, for example, to a rotating shaft mechanism for a notebook computer.
BACKGROUND [0002] With the development of science and technology, different electronic products have increasingly emerged, bringing huge changes to people's lives. In particular, the use of computers has changed people's lifestyles. With the development of materials science and the emergence of smaller integrated chips, computers have evolved into notebook computers that are small, thin, lightweight and easy to carry. Notebook computers are mostly of a flip-type. In order to meet the design requirements of being thin, small and lightweight, they are generally designed to be composed of a base and an upper lid. The base includes a host body and a keyboard, and the upper lid includes a display screen and a lid body. When the notebook computer is not in use, the upper lid is usually closed onto the base. When the notebook computer is in use, the upper lid has to be opened upward to an appropriate angle so that the notebook computer can be operated and used.
[0003] In a rotating shaft of a notebook computer, typically, a pivot of the rotating shaft is directly provided with an annular oil-guiding groove. At the same time, a zinc alloy is used as the material of the rotating shaft. Such a design has the following disadvantages: the rotating shaft of notebook computer having this structure has a low heat-dissipation speed and heating phenomenon in localized parts, and causes lubricating oil in an oil tank to be easily melted. This requires a higher melting point of the lubricating oil in the oil tank. The annular oil-guiding groove disposed on the pivot is not advantageous for the storage of the lubricating oil. Under
2020100008 03 Jan 2020 this arrangement, when the upper lid of the notebook computer is lifted or closed, it may cause oil leakage; at the same time, the annular oil-guiding groove disposed on the pivot is also not advantageous for the formation of a uniform oil film.
