Notebook computer and rotating shaft device

Abstract

The invention provides a notebook computer and a rotating shaft device. The notebook computer comprises a liquid crystal display, a host and a rotating shaft device for connecting the host and the liquid crystal display. The rotating shaft device comprises a rotating shaft body, a limit part and a rotating part, wherein the rotating shaft body comprises a first mandrel, a second mandrel and connecting rods for connecting the first mandrel and the second mandrel; the limit part is arranged on the rotating shaft body and comprises a first lug boss and a second lug boss; the rotating part comprises a first shaft sleeve and the second shaft sleeve, wherein the first shaft sleeve is internally provided with a first damping material; a third lug boss is arranged on the edge at one end of the first shaft sleeve; the first shaft sleeve is sleeved on the first mandrel; at least one point of the third lug boss contacts with at least one point of the first lug boss; the second shaft sleeve is internally provided with a second damping material; and a fourth lug boss is arranged on the edge at one end of the second shaft sleeve. By the invention, two rotating shafts are respectively pivoted with an LCD part and a host part of the notebook computer and can smoothly and reliably rotate at 0 to 360 degrees.

Description

technical field [0001] The invention relates to the shaft technology of a notebook computer, in particular to a notebook computer and a shaft device capable of synchronously rotating 360 degrees. Background technique [0002] For traditional notebook computers, due to the design limitation of the hinge, the LCD screen can only be opened and closed from 0° to 180°. Although there is already a hinge that can be freely opened and closed from 0° to 360°, it has not been successfully applied to a notebook computer so far due to a series of congenital defects. [0003] In the process of realizing the technical solution of the present invention, it is found that the existing 360° rotating shaft has the following disadvantages that cannot be overcome: [0004] 1) The 360° rotating shaft of the gear scheme, the rotating shaft with gears is difficult to implement on the product, its rotation track is controlled by the contour of the gear, because the torque of the four mandrels is di...
