Rotating shaft

Abstract

The embodiment of the invention discloses a rotating shaft. The rotating shaft comprises a plurality of connecting assemblies, a connecting shaft and a fixing shaft. The connecting assembly is of a sheet structure, sawtooth structures are arranged at the front end and the rear end of the connecting assembly respectively, a circular through hole and a runway-shaped through hole are formed in the positions close to the front end and the rear end respectively, and two semicircular notches are formed in the upper end or the lower end of the corresponding positions of the circular through hole andthe runway-shaped through hole. During assembly, the connecting parts are parallel to each other and are arranged in a staggered manner, and the circular through holes of the connecting assemblies arealigned with the runway-shaped through holes of the left and right adjacent connecting assemblies. The connecting shafts are inserted into the circular through holes of the connecting assemblies andfixed into the circular through holes, and the fixing shafts are arranged in the semicircular notches of the connecting pieces and fixed to the two connecting assemblies on the outermost sides of theleft side and the right side. When the rotating shaft rotates, the connecting assemblies rotate on one side of the fixing shaft along the fixing shaft, and the problem that arc length compression occurs on one side of the fixing shaft in the rotating process is solved.

Description

technical field [0001] The invention relates to the field of rotating shaft connection, and more specifically, relates to a rotating shaft. Background technique [0002] The current smartphone market tends to be saturated, and the full-screen technology has reached the bottleneck. Users' aesthetics of mobile phones have begun to weaken, and their desire to purchase phones has been greatly reduced. In order to increase users' desire to purchase phones, various terminal manufacturers began to seek a higher screen-to-body ratio to improve user experience and increase immersion during use, thereby arousing users' desire to change phones. [0003] The current solutions to increase the screen-to-body ratio include a lifting camera solution, a front and back dual-screen solution, and a water drop screen solution. However, these solutions have not fundamentally changed the shape and structure of smartphones, and cannot solve the problem of aesthetic fatigue of consumers. In order ...
