Rotating shaft

Abstract

The embodiment of the invention discloses a rotating shaft which comprises a plurality of first connecting assemblies, a plurality of second connecting assemblies and a fixing shaft, the first connection assemblies and the second connection assemblies are the same with each other in size, the first connecting assembly is of a sheet structure, sawtooth structures are arranged at the front end and the rear end of the first connecting assembly respectively, protruding shafts and runway-shaped through holes are formed in the left side and the right side of the front end and the rear end of the first connecting assembly, and two semicircular notches are formed in the upper end or the lower end of the first connecting assembly. The second connecting assembly is similar to the first connecting assembly, and only one side of the second connecting assembly is provided with a protruding shaft; during assembly, the second assemblies are arranged at the left end and the right end, the first assemblies are arranged between the second assemblies in a staggered mode, the shafts of the first assemblies are aligned with the runway-shaped through holes of the left-right adjacent second assemblies, and the shafts of the second assemblies are aligned with the runway-shaped through holes of the adjacent first assemblies or second assemblies. And the fixed shaft is arranged in each semicircular notch and is fixed on the second connecting assemblies at the left end and the right end. During rotation, the rotating shaft rotates along the fixed shaft, and the problem of arc length compression in the rotation process of one side of the fixing shaft is avoided.

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 ...
