Rotary shaft device and electronic equipment

Abstract

The invention provides a rotary shaft device and electronic equipment. The rotary shaft device comprises a rotary shaft, a first platy connecting part rotationally connected with the rotary shaft, a torsion mechanism for providing first torsion of the rotary shaft relative to the first platy connecting part, and a torsional spring for providing second torsion of the rotary shaft relative to the first platy connecting part, wherein the torsional spring is arranged on the rotary shaft in a sleeving mode; one end of the torsional spring is fixed to the rotary shaft, and the other end of the torsional spring is fixed to the plate face of the first platy connecting part; when the opening angle of a first body and a second body which are connected with the rotary shaft device is 90 degrees, thetorsion of the torsional spring is zero; and the torsion of the torsional spring is always increased gradually when the opening angle of the first body and the second body is decreased or increased from 90 degrees. When the opening angle of the first body is small or big, the first body is supported by the first torsion provided by the torsion mechanism and the second torsion provided by the torsional spring and prevented from rotating automatically due to gravity, and the stability of the opening degree of the first body relative to the second body is improved.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, relates to a rotating shaft device, and also relates to an electronic equipment. Background technique [0002] In the prior art notebook computer, the hinge device connecting the display and the base only provides the supporting force of the display through a constant torsion force. In this way, when the display is less than 30 degrees or greater than 150 degrees, it is easier to automatically fall down, and the display is stable. Sex is poor. Contents of the invention [0003] In view of this, the object of the present invention is to provide a rotating shaft device to improve the stability of the opening angle of the connected first body relative to the second body. [0004] Another object of the present invention is to provide an electronic device having the above-mentioned rotating shaft device, so as to improve the stability of the opening angle...
