Hinge module for folding units

Abstract

The invention relates to a hinge module of a folding device, which is connected with two housing bases, so that the matching flexible display can be turned into a folded or non-folding shape with relative flipping, and each housing base includes two housings that can slide relatively Body, the shaft module includes a base and two sliding mechanisms, one end of the two transmission parts of each sliding mechanism is pivotally connected to the two pivoting parts at each end of the base, and then through the opposite end of a respective linking part and each The sliding parts are respectively connected to one housing, and the guiding structure is set on the side and end sides between the two housings, through the transmission effect of each intermediate transmission part between each linkage part and each sliding part, and each housing The mutual guidance between them enables each shell base to expand and contract stably, and uses the displacement path to compensate for the length change of the flexible display after bending, so that the bending part has a small curvature.

Description

technical field [0001] The invention relates to a hinge, in particular to a hinge module of a foldable electronic device. Background technique [0002] The applicant once applied for an invention patent application entitled "Rotating Shaft Module of a Folding Device" (application number is Taiwan, China TW107113396 / CN201810371007.2, hereinafter referred to as the previous case 1), and one embodiment includes the first support piece, a pair of split shafts, a second support, a multi-axis shaft, and a third support for use with a flexible display, so that after the whole is folded into an S-shape, the second split shaft connected The first supporting member and the second supporting member can be closed, and will form an accommodating space inside the split rotating shaft to accommodate the curved area of ​​the flexible display, but in terms of the multi-axis rotating shaft, it is limited It is limited to keep a sufficient distance between the four shafts for the installation...

[0002] The applicant once applied for an invention patent application entitled "Rotating Shaft Module of a Folding Device" (application number is Taiwan, China TW107113396 / CN201810371007.2, hereinafter referred to as the previous case 1), and one embodiment includes the first support piece, a pair of split shafts, a second support, a multi-axis shaft, and a third support for use with a flexible display, so that after the whole is folded into an S-shape, the second split shaft connected The first supporting member and the second supporting member can be closed, and will form an accommodating space inside the split rotating shaft to accommodate the curved area of ​​the flexible display, but in terms of the multi-axis rotating shaft, it is limited It is limited to keep a sufficient distance between the four shafts for the installation of other components (such as linkages, friction plates, linkage plates and stoppers, etc.), so after the overall folding, the multi-axis shaft There will be a gap between the connected second support and the third support. When the flexible display needs to be arranged on the same side of the three supports, the split shaft and the multi-axis shaft, the aforementioned spacing will affect the overall thickness
