Title:
DUAL-AXIS TORQUE HINGE
Document Type and Number:
WIPO Patent Application WO/2023/033093
Kind Code:
A1
Abstract:
Provided is a dual-axis torque hinge capable of moving a first shaft and a second shaft one at a time in order. This dual-axis torque hinge is equipped with a plurality of stacked first friction elements (6) which engage a first shaft (4), and a plurality of stacked second friction elements (7) which engage a second shaft (5). The first friction elements (6) have an arm (6a) wound around the first shaft (4), and are configured in a manner such that the tightening torque when the first shaft (4) rotates relative to the first friction elements (6) in a tightening direction is greater than the loosening torque when said shaft rotates relative to said elements in a loosening direction. The second friction elements (7) have an arm (7a), and are configured in a manner such that the tightening torque when the second shaft (5) rotates relative to the second friction elements (7) in a tightening direction is greater than the loosening torque when said shaft rotates relative to said elements in a loosening direction. When a second main body (2) rotates in a first direction relative to a first main body (1), tightening torque acts on one shaft among the first shaft (4) and the second shaft (5), and loosening torque acts on the other of said shafts.
