Rotating shaft module of folding device

Abstract

The invention relates to a rotating shaft module of a folding device, wherein one end surface is respectively connected to first and second housings, and the other end surface of the rotating shaft module is connected to a flexible display, so that when the first and second housings reverse relatively, the flexible display is relatively bent. The rotating shaft module includes a base and a first sliding mechanism, wherein the base is located between the first and second housings, and the first sliding mechanism includes a first sliding cover, a support member, a left four-bar linkage mechanismand a swinging member. The first sliding cover is connected to the first housing, and one end of a first linkage member and a second linking member of the left four-bar linkage mechanism are respectively pivotally connected to the base, so that the first sliding cover is linked when the left four-bar linkage mechanism and the swinging member are actuated by relative overturn of the first and second housings, and a supporting portion of the support member is offset by an angle to accommodate a curved portion of the flexible display.

Description

technical field [0001] The present invention relates to a rotating shaft, in particular to a rotating shaft module of a foldable electronic device. Background technique [0002] Traditional foldable electronic devices, such as foldable displays, are mainly connected to the sides of the support members of each display unit through a split hinge or a multi-axis hinge to form a pivot, so that the flexible display or each display unit can be relative to each other. Flip to lift or close. However, since the current electronic devices are mainly designed to be thin and easy to carry, the space between the two bodies that can be left to accommodate the rotating shaft is getting narrower and narrower, and the size requirement of the rotating shaft in terms of thickness is bound to be subsequently reduced. [0003] Therefore, as shown in the patent application for "Foldable Display" with the Patent Publication No. CN105788452 A, a folding structure of a rotating shaft is shown, whi...

Problems solved by technology

[0006] An object of the present invention is to provide a hinge module, through the four-bar linkage mechanism, the gear set and the lever to push the sliding cover and the housing to generate displacement during the overall folding process, so as to generate compensation for the travel path and length Conversion, to compensate the difference between the radius of curvature formed by the bending part of the flexible display and the radius of curvature between the two housings, and at the same time drive the support part to shift to accommodate the structure of the bending part of the flexible display, which can solve the problem of the existing shaft The large overall volume of the folding structure is not conducive to the overall design, but it can effectively reduce the distance between the two bodies when they are closed, so as to reduce the overall volume and facilitate the design, and meet the market demand for thinner overall volume, and in the overall In the structure with reduced thickness, a stable transmission effect can be formed
