The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

Disclosed is a hinge for an inner flexible screen mobile terminal, the hinge comprising a left support structure, a right support structure and a middle support structure, a pair of left connecting arms and a pair of right connecting arms, and a left rotatable support member and a right rotatable support member, wherein the left connecting arms and the right connecting arms are respectively rotatably connected on the left side and the right side of the middle support structure; and the left rotatable support member and the right rotatable support member are rotated downwards to a lower position to leave a space for accommodating a bent portion of the flexible screen when the hinge is folded, and when the hinge is rotated to a state corresponding to the spreading of the flexible screen, the left rotatable support member and the right rotatable support member are rotated to a higher position, and the left support structure and the right support structure are respectively provided with a rotation guide structure for the left rotatable support member and the right rotatable support member. The hinge of the present invention has a simple and reliable structure, and when applied to a mobile terminal such as a mobile phone, an e-book or a computer, the hinge can be used as both a hinge and flexible screen support structure therein.

The description relates to hinged devices, such as hinged computing devices. One example can include a first portion that is secured to a hinge assembly by a first primary hinge shaft and a first secondary hinge shaft that is not co-extensive with the first primary hinge shaft. The example can also include a second portion that is secured to the hinge assembly by a second primary hinge shaft and a second secondary hinge shaft that is not co-extensive with the second primary hinge shaft.

A hinge includes a base frame unit and two rotatable axle units. The base frame unit includes a base seat and a protective cover. The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

A hinge is mountable on a flexible display unit including a housing shell unit and a display unit. The hinge includes a base seat, a torsion module disposed above the base seat and secured to the display unit, and a bracket module disposed below the base seat. The torsion module includes two outer supporting units and an inner supporting unit at two ends and a middle of the base seat. The bracket module has two brackets securely connected to two support plates of the display unit and rotatable relative to the base seat. The hinge is rotatable between an unfolded position where the brackets are in an unfolded state, and an outfolding position where the brackets are close to and face each other. The outer and inner supporting units cooperatively define a semicircular-shaped supporting surface in the outfolding position for supporting the display unit.

Movement system for a closure structure with folding movement, comprising a transmission hinge which connects a first panel to a second panel of the closure structure. The transmission hinge has a first wing fixed to the first panel, a movement lever hinged to the first wing around a first axis, and a second wing which is hinged to the movement lever around a second axis and is fixed to the second panel. The movement system comprises a transmission mechanism which, following the rotation of the first panel, drives the movement lever to rotate around the first axis. The transmission hinge comprises a gear connecting the first wing to the second wing so that, following the rotation of the movement lever, the second wing is actuated by such gear to rotate around the second axis in order to make the second panel rotate with respect to the first panel.

A portable information handling system pivots a hinge rotational axis as the hinge rotates housing portions between open and closed positions to manage a gap between the housing portions. For example, the hinge couples a base at a perimeter of one housing portion, the base having a many body that slides on sliding members of the base and that supports a bracket extending inward to couple to another housing portion. A bracket gear engages with a pinion gear included in the main body to translate bracket rotation through the pinion gear to a rack integrated in the base, thereby sliding the main body relative to the base as the housing portions rotate so that the distance between the housing portions adjusts with rotational orientation.

A hinge structure includes a first rotary bracket that rotates about a first virtual axis and a second rotary bracket that rotates about a second virtual axis The hinge structure also includes a fixed bracket that includes the first rotary bracket and the second rotary bracket fixed thereto. The hinge further structure includes a first rotary member, a second rotary member, a first arm and a second arm. Additionally, the hinge structure includes a cam part that includes bumpy structures. A first elastic body is mounted on the first rotary member and supports at least one side of the cam part and second elastic body is mounted on the second rotary member and supports at least an opposite side of the cam part. The hinge structure also includes a support bracket that supports the first elastic body and the second elastic body.

A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.
