Notebook computer rotation shaft

Abstract

The invention discloses a notebook computer rotation shaft, belonging to the technical field of rotation shaft devices. The notebook computer rotation shaft comprises a shaft lever and a pivot, wherein a surface plate is arranged at one end of the shaft lever, and more than two lever holes connected with a computer in a locked mode are arranged on the surface plate; the other end of the shaft lever is provided with a hollow shaft barrel made of elastic materials; a surface plate is arranged at one end of the pivot, and more than two lever holes connected with a computer in a locked mode are arranged on the surface plate; the other end of the pivot is provided with a shaft post whose shape fits that of the shaft barrel and whose size is slightly bigger than that of the shaft barrel; the barrel post is made of elastic materials, and a plurality of grid holes are evenly arranged on the surface wall of a part of the shaft barrel, into which the shaft post is inserted; a gasket is fixed onthe other part of the shaft post, and notches with a proper angle is formed at the upper edge of the gasket; a lug which extends outward is arranged at the upper edge of the tail end of the shaft barrel, and the lug is arranged among the notches. The notebook computer rotation shaft has the advantages of simple structure, low cost and favorable positioning effect, and can effectively reduce friction.

Description

technical field [0001] The invention relates to a rotating shaft device, in particular to a rotating shaft device used in a 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 the keyboard, and the upper cover composed of the display screen and the cover. .

Problems solved by technology

[0005] 2. The rotating shaft of the notebook computer in the prior art needs to be locked after the rotating shaft is rotated, so that the upper cover and the base are at a corresponding angle without loosening. The locking structure of this part is often very complicated in design, high in cost and long in production time , but the resulting locking effect is not very suitable. Some are too tight and the rotation friction is too large to easily damage the shaft, and some are too loose and cannot achieve a good locking effect.

[0006] 3. In the prior art notebook computer, when in use, the rotation angle is sometimes too large, which causes the angle between the upper cover and the base to be relatively large, which may cause damage to the rotating shaft during rotation, and it is not very convenient to use at the same time
