Pivot device, supporting device and electronic equipment

Abstract

The invention discloses a pivot device, a supporting device and electronic equipment. The pivot device comprises a first gear set, a second gear set and connecting parts, wherein the first gear set comprises a first gear and a second gear which are meshed with each other, and the diameter of the second gear is less than that of the first gear; the second gear set comprises a third gear and a fourth gear which are meshed with each other, and the third gear and the second gear rotate synchronously; the ends, away from each other, of a gear shaft of the first gear and a gear shaft of the fourth gear extend outwards to form a first axis and a second axis respectively; each connecting part is provided with a sleeving part and a mounting part which are connected with each other, the first axis and / or the second axis are / is sleeved with the sleeving parts, and the first axis and / or the second axis can rotate in shaft holes of the sleeving parts; and the first axis rotates to sequentially drive the first gear, the second gear, the third gear, the fourth gear and the second axis to rotate, and the rotating speed of the first axis is less than that of the second axis. The pivot device can prevent electronic equipment from falling backwards.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a hinge, a supporting device and an electronic equipment. Background technique [0002] At present, mobile terminals, ie, mobile phones and tablet computers, generally have larger display touch screens, which allow users to directly touch and control without using external devices such as a mouse. However, when using a mobile terminal for office work or playing games, a keyboard is still needed to improve the convenience of use. to a certain angle. However, since the keyboard is the base in this case, and the mobile terminal integrating the host and the screen is the rotating part, the weight of the rotating part exceeds the weight of the base. When the rotating part rotates to a large angle relative to the base, the base will not be able to independently After the effective support of the rotating parts is completed, the whole device will fall backwards, which wil...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to solve the existing rotating part and base connected to the hinge. If the weight of the rotating part exceeds the weight of the base, the rotating part will fall backward when the rotating part rotates to a large angle relative to the base. , problems affecting users
